3851 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3853 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3854 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3856 One basic decision: e.g. src/clean.mk includes further files. In order
3857 to make this work there are two solutions:
3858 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3859 run configure on them. This way they can use
3860 'include $(srcdir)/port-clean.mk'
3861 - always include clean.mk by the Makefile at the same level. To avoid
3862 that `make clean` tries to include and build Makefile.dep the
3863 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3864 implemented, because now even `make uninstall` doesn't create
3865 Makefile.in. clean.mk could be eliminated by pasting it in
3868 * debugger/mcs51/Makefile.in: build own objects from library sources
3869 (SLIB, SDCC) in current directory
3871 * configure, configure.in: renamed --disable-device-lib-build in
3872 --disable-device-lib; added --enable-doc, the required tools are
3873 searched by configure; added result message; the toolchain for the
3874 belonging ports are now only built, if the port is enabled.
3876 * support/regression/*: all output is written in directory gen, because
3877 the fwk and ports directories don't livet in the build tree using vpath
3879 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3880 --disable-device-lib, added --enable-doc, added section VPATH
3882 * sim/ucsim/configure.in,
3883 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3884 z80 are enabled by default
3886 2006-04-24 Raphael Neider <rneider AT web.de>
3888 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3889 to config word, "pic14_"-prefixed some extern functions
3890 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3891 config word has been found
3892 * src/pic/device.h: added prototypes
3893 * src/pic/pcode.c: added "pic14_"-prefix where needed
3894 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3896 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3898 (pic14emitRegularMap): ignore config words,
3899 (pic14createInterruptVect): moved generating __config directives away
3900 (picglue): have __config directives emitted
3902 2006-04-24 Borut Razem <borut.razem AT siol.net>
3904 * doc/Makefile: sync with nightly build makefile
3906 2006-04-24 Raphael Neider <rneider AT web.de>
3908 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3909 registers that have not been assigned proper liveranges,
3910 fixes #1469504 and #1474602,
3911 (pCodeRegOptimizeRegUsage): fixed typo in comment
3913 2006-04-24 Borut Razem <borut.razem AT siol.net>
3915 * device/examples/main8051.c: deleted - it was removed from CVS
3916 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3917 after the transition to Subversion
3918 * src/SDCCalloc.h: deleted - it was removed from CVS
3919 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3920 after the transition to Subversion
3921 * sim/ucsim/cpu.gif, sim/ucsim/interrupt.gif, sim/ucsim/new.gif,

4157 implemented patch 1120823 Thanks to Willy De la Court (normal
4158 interrupts need an interrupt number now if they are made critical),
4159 and enabled nesting of critical functions though not for gbz80
4160 (genCritical, genEndCritical): added functions
4161 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
4162 * src/z80/mappings.i: added "ei" to all mappings

4174 the left operand is shorter than the result (c* = lit-c* + int),
4176 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
4179 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4181 * src/.version: increased version number to 2.5.5
4182 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
4183 linking is done manually in pic16 port's _linkEdit,
4184 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
4185 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
4186 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
4187 allocate asmop as AOP_ACC,
4188 (aopForRemat): added parameter 'bool result' in function declaration,
4189 (pic16_aopGet): return AOP_ACC when accessing WREG,
4190 (pic16_popGetTempReg): minor modification,

4201 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
4202 call to allocReg, not by manually allocating a new one,
4203 (pic16_assignRegisters): now before going through the register
4204 allocating functions mark all registers as free. This eliminates some
4205 side effects resulting from peephole parser done earlier in the backbone
4207 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

4257 2006-03-06 Borut Razem <borut.razem AT siol.net>
4259 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
4260 made the linker quiet
4262 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

4265 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
4266 which dumps before the function entry point a data byte which represents
4267 the number of the local variables used by the specified function, added
4268 'xinst' for initial support for Extended Instruction Support,
4269 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
4270 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
4271 port->fun_prefix anymore (may change later),
4272 (genFunction, genEndFunction): do not store/restore local registers for
4273 _main (this should take care the --main-return command line option in
4275 (genOr): removed some legacy pic-port instructions,
4276 * src/pic16/genarith.c (genAddLit): re-enabled old code because
4277 performing operations with SFR's causes data to be written more than
4278 once to each SFR. Perhaps SFRs should be handled in special cases...
4279 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
4281 * src/pic16/main.c (_process_pragma): stack bound checking did not take
4282 into account for stack starting position,

4284 --extended or -y for Extended Instruction Support,
4285 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
4286 (deassignLRs): *** perhaps the most important change, old 'for' code
4287 (commented out for reference), didn't account for some registers which
4288 were left marked 'not free' after a pointer operation. The change
4289 reduces register usage a lot in some cases
4291 2006-03-04 Borut Razem <borut.razem AT siol.net>

6564 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6565 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6566 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6567 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6568 always available in leading double underscore form. The C99 support is
6569 mostly missing, but it's a start.
6570 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6571 reserved identifier "__data".
6573 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

6649 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6651 * device/lib/printf_large.c: removed inline assembly for portability and
6652 readability. Use printf_fast if speed or size are more important.
6653 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6654 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6656 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6658 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6659 prevent compiler warning
6661 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6663 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6664 moved to level 0 and declared as static. Also they are explicit
6665 placed in access bank. This was necessery because some times they
6666 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6667 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6668 optimizations. Currently only compare to unsigned char is implemented,
6669 * src/pic16/gen.c: added fReturnIdx array,
6670 * (struct resolvedIfx) is moved to gen.h and made public,
6671 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6672 * (aopForSym): added an optimization to directly store in stack of
6673 the operand of a SEND iCode,
6674 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6675 but as registers instead (AOP_REG) using the fReturnIdx array,
6676 * (pic16_freeAsmop): remove the freed register from the
6677 _G.sregsAlloc field,
6678 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6679 a compare of 'WREG',
6680 * (pic16_popGetTempRegCond): changed function prototype, now
6681 function takes also a bitVector argument v which holds the current
6682 set of registers that are allocated for stack access by aopForSym,
6683 registers allocated in aopForSym for accessing stack symbols are not
6684 any more part of the functions usedRegs field,
6685 * (genCall): some times aopOp is called for a stack variable to be
6686 send, aopForSym might perform the push, if this is true make sure
6687 that genCall doesn't push the variable twice by testing _G.resDirect,
6688 * (genFunction): changed testing for unspecified interrupt number
6689 from 256 to INTNO_UNSPEC,
6690 * modified selection scheme of frame pointer generation. Previously
6691 if function did use local registers a frame pointer was generated,
6692 now a frame pointer is generated only if function has arguments
6693 (that need PLUSW2 register access), or has stack arguments, or the
6694 compiler is not instructed to omit the frame pointer,
6695 * (genEndFunction): before restoring local registers that were saved
6696 in the function preamble, also restore the registers that *might*
6697 have been allocated for stack access,
6698 * (genRet): removed some old comments,
6699 * (genCmp, the active (RN's) version): added a call to the
6700 pic16_genCmp_special function to perform the compare with a more
6701 robust and optimized way,
6702 * (genInline): a feature has been added in inline code generation,
6703 which allows a wildcard variable substitution when writing inline
6704 assembly. Code is incomplete and experimental therefore undocumented,
6705 * (genCast): changed order of aopOp for result and right to allow
6706 aopForSym to directly load the result if possible,
6707 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6708 perform an optimized compare on some selected special occasions,
6709 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6710 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6711 generate an IVT any more,
6712 * src/pic16/main.c (pic16_optionsTable): added command line option
6714 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6715 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6717 * src/pic16/NOTES: Raphael Neider added in list of active developers
6718 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6719 jumptable_end to prevent bug #,
6720 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6721 inCond and outCond fields,
6722 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6723 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6724 turn off register spilling,
6725 * (packRegsForOneUse): synced with other ports' versions although it
6726 is not used currently,
6727 * (pic16_packRegisters): added an optimization while reading
6728 structure bitfields, some registers may be saved (malloc code is
6729 decreased by 80 bytes)
6731 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6733 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6734 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6735 this can be optimized more?
6737 2005-03-10 Raphael Neider <rneider AT web.de>
6739 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6740 genNearPointerGet): (hopefully) fixed access to bitfields via
6741 pointers (p->bitN = x; and x = p->bitN; failed)
6743 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

7375 Adding support for replacing ljmps with sjmps in jumptables
7376 generated for switch statements. For now you need to set the
7377 environment variable SDCC_SJMP_JUMPTABLE to enable this.
7378 Now 4 algorithms for mcs51 jumptable generation are used:
7379 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
7380 addresses loaded pc-relative for up to 112 cases and stack-pushing
7381 target addresses loaded with offset from dptr for up to 256 cases.

7408 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
7409 to call when a stack overflow occurs,
7410 * (malloc.h): added CVS Id tag,
7411 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7413 * added libc directory. The current version of LibC contains string
7414 functions, ctype functions and macros and some functions of the
7415 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7416 be extensively tested in the future. Standard disclaimer here.
7417 Library is not automatically build yet. But one can build it by
7418 invoking 'make' inside the libc directory.
7419 * added ADC library under libio. Preliminary version yet.
7421 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

7428 * (genUminusFloat): fixed for pic16, ported code from mcs51,
7429 * (pic16_storeForReturn): optimized return of 0,
7430 * (genCmp): experimental code for new genCmp which uses PIC18's
7431 special compare&skip instructions. Initial tests fail some times
7432 with variables grater than 1 byte in size, so new code is disabled,
7433 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7435 * (genCast): began a fix to optimize the casting of a bit to another
7436 bit, now assigning a bitfield to another bitfield will fail, sorry,
7437 * src/pic16/main.c: disabled the use of lr-support feature,
7438 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

7441 bits with offset (case PO_GPR_BIT),
7442 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
7444 * (isBankInstruction): modified to return 0 for no banking instruction,
7445 and 1 for banking instruction,
7446 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7447 caused stop processing pCodes after a inline assembly block,
7448 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
7449 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
7450 registers when it shouldn't,
7451 * src/pic16/ralloc.c (allocReg): add preliminary support for
7452 supporting a limited set of temporary registers,
7454 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7456 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
7457 genDataPointerSet): ensure assignments always copy in MSB to LSB
7459 (loadRegFromAop): recognize CLRH optimization,
7460 (genFunction): optimize RECEIVE iCodes in reentrant functions
7462 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7464 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7478 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
7480 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

10389 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
10390 must not cause an unsigned operation
10391 * src/pic/glue (pic14emitRegularMap),
10392 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
10394 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
10396 * src/pic/pcode.c (PCodeID): commented out left over debug code
10398 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
10400 * support/valdiag/tests/overflow.c: added shift tests
10401 * src/pic/device.c,
10408 * src/pic/pcodepeep.c,
10409 * src/pic/pcoderegs.c,
10410 * src/pic/ralloc.c,
10411 * src/pic/ralloc.h: applied patch from Slade Rich;
10412 added support for multiple code pages and multiple RAM banks on the
10413 PIC 14 port. The ASM files now no longer simply assume all the
10414 code / RAM are in the same page / bank. This means the linker can
10415 safely allocate code/RAM of separate ASM files to different pages/banks.
10416 * doc/sdccman.lyx: added Slade's tips
10417 * src/mcs51/peeph.def: fixed bug #880768

10426 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
10429 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
10430 strtof is not part of C89 and isn't included with Mac OS X.
10432 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10434 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

10459 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10461 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10462 loaded with the linker search paths (-L arguments) and the libraries
10463 to be linked with the current source (-l arguments). Changes
10464 currently will affect only the pic16 port.
10465 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10466 include path the port specific paths and port specific libraries,
10467 * gplink command now contains the $3 argument,
10468 * src/pic16/device.h,
10469 * src/pic16/device.c,: structure PIC_device is made public and
10470 renamed to PIC16_device, the same for variable Pics which is renamed
10471 to Pics16. Updated all references to them.
10472 * src/pic16/glue.c (pic16glue): corrected bug with code
10473 initialization which bypassed the variable initializations block.
10475 * device/lib/pic16/Makefile.rules: removed --penable-stack from
10476 COMPILE_FLAGS and added the --nostdinc option

10480 * device/include/mc68hc908jb8.h: Register defs for another member
10481 of the hc08 family. Contributed by Bjorn Bringert - thanks!
10483 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10485 Documenting changes from previous commits.
10486 * configure.in (version 1.56),
10487 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10488 when generating output files to configure the pic16 library,
10489 but now I've commented it out, since gputils aren't installed in the
10490 SF compile farm, so library won't compile
10492 * device/lib/Makefile.in (version 1.56): initially I've added in
10493 target 'all' the prerequestive 'model-pic16' so it compiled the
10494 pic16 library, but now I've commented it out for the same reasons
10496 * added targets 'model-pic16' and 'objects-pic16' to compile the
10498 * added target 'port-specific-objects-pic16' to handle the
10499 generated libraries and copy them into the build/ directory
10500 * added target 'clean-intermediate-pic16' to clean intermediate
10501 files into pic16 directory
10502 * in target 'installdirs' added line to create directory pic16 in
10503 the installation path
10505 * device/include/Makefile.in (version 1.11): in target 'install'
10506 added lines to copy all header files to installation path,
10507 * in target 'installdirs' added line create directory for pic16
10508 headers in the installation path
10510 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

10521 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10523 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10524 option so that it actually works. Made it specific to the z80, since
10525 the gbz80 doesn't have these kinds of I/O ports.
10527 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10529 * device/include/z180.h,

10551 Mainly changes to support compilation of the device libraries
10552 * src/pic16/device.c: stack is allocated via symbol and not
10553 via literal number. The symbol is placed in the corresponding
10554 position of the data ram
10555 * (pic16_dump_section): relocatable and absolute uninitialized
10556 data are now emitted in sorted order to reduce section naming,
10557 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10558 weren't marked as being in the access bank,
10560 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10562 Added portion of GNU PIC Library under the directory
10563 device/include/pic16 and device/lib/pic16. These files
10564 contain the declarations of SFRs for the PIC18Fxx2 devices.
10565 The directory is initialized via configure from toplevel.
10567 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10569 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
10570 the spilllocations to be compared correctly
10572 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
10574 * src/SDCCast.c (decorateType): fixed bug introduced today
10576 2004-01-12 Borut Razem <borut.razem AT siol.net>
10578 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

10594 * doc/sdccman.lyx: Moved and added some sections, small changes
10595 all over. Telling LaTeX to be less strict with word spacing
10596 to better keep the right margin. Changed some notes about
10597 maintainance of the ports in section 3.2.1 - is it OK like this?
10599 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
10601 SDCC source changes:
10602 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

10636 UPPER for immediate operands,
10637 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
10639 * src/pic16/peeph.def: all peepholes with movff are commented out,
10640 because there is a problem in the pcode peep optimizer,
10641 * src/pic16/ralloc.c: the register allocator can now reuse local
10642 function symbols for another function. This saves register usage.
10643 * src/pic16/ralloc.h: added flag isLocal in structure regs,
10645 Added file src/pic16/NOTES with information about program writing on
10646 the current port version.

10650 * src/mcs51/peephole.def: added peepholes 177.c,d (redundant moves)
10651 and peephole 252 (array access)
10653 2004-01-09 Borut Razem <borut.razem AT siol.net>
10655 * src/SDCCmain.c : fixed #872250: -l command line defined library

10675 gen51Code): more efficient parameter receive for --model-large
10678 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10680 * src/ds390/main.c,
10681 * src/z80/main.c: added missed needLinkerScript flags (more than
10682 one port structure defined in these file)
10683 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
10686 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>
10688 * src/SDCCmain.c: removed various references to DEFAULT_PORT
10689 * src/port.h: added flag needLinkerScript in port->linker

10703 override default uninitialized data segment definition for
10704 devices only with SHAREBANK memory (reported from Erik Epetrich)
10705 * (pic14emitOverlay): modified to emit a commented overlay segment
10706 directive when no overlay data exist
10707 * (picglue): modified to emit uninitialized data segment
10708 according to udata_section_name

10716 changed size of fptr from 2 to 3 in port structure
10718 2004-01-07 Borut Razem <borut.razem AT siol.net>
10720 * support/scripts/sdcc.nsi: update PATH
10721 * support/scripts/sdcc.ico: craeted

10756 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10758 A python script to validate compiler diagnostic messages. It can be
10759 used to verify that sdcc complains about bad c source code and
10760 gives a good location of the error.
10761 * support/valdiag/Makefile,
10762 * support/valdiag/valdiag.py,
10763 * support/valdiag/tests/*
10765 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10776 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10778 * src/common.h: added ifndef/define/endif macros
10779 around the header file.
10780 Bug reported from Jesus Calvino-Fraga
10782 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10784 * sdcc.spec: updated
10785 * device/include/Makefile.in: don't install CVS directories
10786 * device/lib/Makefile.in: added removal of CVS directories after install
10787 * doc/Makefile: fixed install, added local_icons
10788 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
10789 * src/mcs51/gen.c (genRightShift): fixed bug #870788
10790 * src/ds390/gen.c (genRightShift): fixed bug #870788
10791 * src/SDCCast.c (decorateType): fixed bug #870781
10793 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10795 PIC16 port related changes:
10796 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10797 added variable stackPos,
10799 * gen.c: genCall, assignResultValue: added support for
10800 pushing/retrieving function parameters to/from stack,
10801 genFunction,genEndFunction: setup stack frame for the
10802 generated function,
10803 genAddrOf: will be changed according to bug 863624
10805 * added files genutils.c and genutils.h which contain gen*
10806 debugged and optimised functions extracted from gen.c
10808 * glue.c: added variable 'externs' which holds extern symbols,
10809 pic16emitRegularMap: is modified to properly handle relocatable
10810 symbols under the new scheme,
10811 pic16createInterruptVect: is modified
10812 pic16printPublics: is modified to emit 'global' assembler directives,
10813 added pic16_printExterns to print extern symbols,
10814 pic16glue: initializes stack/frame pointer in the beginning of
10815 the assembly output. Temporary hack, will be corrected later,
10816 because gplink yet does not support stack and SDCC does not
10817 yet support a type of crt0.o object to create the final binary.
10819 * Removed many lines that contain 8051 legacy code.
10820 * The code is finally placed under a 'code' directive.
10821 * Added port specific options.
10823 * _process_pragma: simplified since now we do not need *special*
10824 include file to define SFR registers. But a separate header
10825 will be needed. This will be developed later.
10826 * _pic16_parseOptions: added, parses port specific options:
10827 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10828 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10829 --preplace-udata-with=
10831 * _pic16_setDefaultOptions: modified to initialize section names,
10832 but hack is temporarly out of order since it needs improvement.
10833 * _pic16_genAssemblerPreamble: configuration words are emitted by
10834 their address instead of their name. This part is incomplete and
10835 supports only the 18Fxx2 devices. Other devices will emit an error
10836 during assembly since they do not contain the same set of config
10838 * _pic16_genIVT: is modified,
10840 * pcode.c: added definitions for some hardware registers that are needed
10842 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10843 All PCI entries are updated. Now LFSR is supported.
10844 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10845 * added pic16_newpCodeOpLit2 to support instructions with
10846 two literal arguments
10847 * pic16_pCode2str: corrected code that emits assembler instructions
10848 with two literal operands and those that have an access bit modifier
10849 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10850 this fixes a bug which caused some labels to be lost, when an
10851 assembler directive was added, i.e. banksel,
10852 * pic16_FixRegisterBanking: improved logic that causes the insertion
10854 * InlineFunction: functions that are called once, are not any more
10855 inlined. This can be a port option in the future,
10857 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10859 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10860 hold the corresponding uninitialized symbols,
10861 * pic16_allocProcessorRegister: registers have explicit marked the
10863 * pic16_allocInternalRegister: registers are explicit marked as
10865 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10866 processing list, so bit registers were lost,
10869 * ralloc.h: added field 'accessBank' and original symbol operand
10870 in register definition,
10871 * removed the field isMapped from register definition,
10873 ** Several functions have been removed from various sources:
10874 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10875 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10876 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10877 pic16_assignRelocatableRegisters
10879 ** others have been introduced:
10880 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10881 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10883 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10885 * support/scripts/inc2h.pl: changed definition of BIT_AT
10886 to emit 'sbit at' instead of 'bit at'. This was a request.
10888 PIC16 port related preliminary changes:
10889 * gen.c: prefixed function popRegFromString with
10890 pic16_ and all references to it corrected
10891 * pcode.c: all pic16_pc_* hardware registers prefixed
10892 with underscore (_),
10893 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10894 * ralloc.c: newReg(): when register is REG_SFR then
10895 set address to rIdx,
10896 pic16_allocProcessorRegister(): marks register wasUsed=0
10897 pic16_writeUsedRegs(): added a call to assign processor
10898 registers via pic16_assignFixedRegisters
10900 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10902 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10903 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10904 variables in unused register banks. Also the SSEG is placed
10905 wherever there is enough space for it, and IDATA can be anywhere
10906 in internal RAM. For now compile using -Wl-Y[stack_size].
10907 The mem file is different for this option as well, since it
10908 makes no sense of talking about DSEG lenght.
10910 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10912 * src/SDCClrange.c: fixed bug 869095 that caused segfault

11159 it breaks with bitfields, extern declarations, and gcse analysis.
11160 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
11161 could be assigned through a pointer, so don't complain.

11801 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11802 support for standard C idiom of memory mapped variables; for
11803 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11804 to xdata int at 0x1234 tempvar = 1.

11822 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11824 Fixed bug #621531 (const & volatile confusion in the type chain).
11825 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11826 refer to the const or volatile state of the pointer itself.

11903 and JUMPTABLE iCodes properly now (worked by accident before)
11904 * src/mcs51/gen.c (leftRightUseAcc),
11905 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11906 iCode properly now. Use getSize instead of nRegs since a & b
11907 aren't part of the nRegs tally.
11909 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11911 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11921 copied from genNearPointerSet()
11922 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11923 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11924 If they pop r0/r1 they must be called in the opposite order than aopOp().
11925 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11926 (resp. --stack-auto), prepared for --xstack
11928 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11937 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11939 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11940 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11941 type for bits was changed. It resulted in bit variables becoming
11942 global, which is not permitted in PIC 14 assembly output.
11944 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11946 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11948 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11950 Z80 and MCS51 linkers complaint if a public symbol is defined
11951 in more than one library module:

11957 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11959 A few small changes that speed up the peephole optimizer.
11963 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11965 Try to make the peephole optimizer smarter by maintaining
11966 an association between the assembly source code and the
11967 iCodes that originated them. Put this information to use
11968 with a new peephole rule condition "notVolatile" so that
11969 the rules can be aggressive yet still safe.
11974 * src/mcs51/peeph.def
11976 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11980 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11981 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11982 if the left or right operand symbols have the accuse flag set.
11984 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11986 Changed the type of the result of the ! (NOT) operator to char;
11987 previously it returned the same type as the source. This allows
11988 us to eliminate all the genFloatNot functions (all of its target
11989 implementations were very buggy) since !float can use the same
11992 * src/SDCCicode.c (ast2iCode): ! returns char
11993 * src/mcs51/gen.c (genNot, genNotFloat),
11994 * src/ds390/gen.c (genNot, genNotFloat),
11995 * src/z80/gen.c (genNot, genNotFloat),
11996 * src/pic/gen.c (genNot, genNotFloat),

12001 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
12002 1. Interrupt would not compile properly. Ensure PCLATH register is saved
12003 during interrupts. Ensure WSAVE is located at a shared bank address.
12004 2. Fixed page selection in some places
12005 3. Fixed BTFSS/C to where necessary use registers directly and not simply
12006 the registers name strings.
12007 4. Fixed "signed / unsigned compare" compiler warnings.
12008 5. The PIC port manages its own allocation of the general purpose
12009 registers, but makes no attempt to reuse them. As a result when
12010 compiling it soon runs out of general purpose registers. Some
12011 additional code was added to the files pcode.c and device.c to walk
12012 through the function call tree and rename the registers so that they
12022 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
12023 genPlus() & genMinus() when the result is the same as left or right
12025 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

12029 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
12031 Made bitfield a distinct type from bit so that bitfields
12032 convert as per ANSI C and bits retain their traditional
12033 boolean style behaviour. Implemented bitfield support in
12041 * src/ds390/gen.c: bit v bitfield split
12042 * src/z80/gen.c: New support for bitfields
12043 * support/regression/tests/bitfields.c: reenabled z80,
12046 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
12048 Rules 246.x, 247.x relate to bitfields, the others speed up
12049 access to xdata mapped I/O devices.
12051 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
12053 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
12055 Cleaned up genPackBits and genUnpackBits and added two helper
12056 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
12057 for literal assignments in genPackBits (thanks to Frieder for
12063 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
12065 Fixed bug #748310 (pointer to function type mishandled when the
12066 function name is omitted). Also fixed a SIGSEGV when a function
12067 attribute (reentrant, etc) is used on a non-function or on a
12068 function but misplaced before the parameter list.
12070 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
12072 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
12073 * support/Util/SDCCerr.h,
12074 * support/Util/SDCCerr.c: Added func attr misuse error msg
12076 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
12078 Fixed bug #787649 by anonymous
12079 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
12080 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
12082 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
12084 Fixed numerous bitfield problems.
12086 * src/SDCC.y: More bitfield related error checking

12095 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
12097 Made the constant following the "interrupt" keyword optional. If
12098 omitted, the function will not automatically be given an entry
12099 in the interrupt vector table (similar to #pragma NOIV, but
12100 less syntacticly kludgy). The interrupt number is also now
12101 range checked. Also fixed a bug in the high order bit example
12108 * support/Util/SDCCerr.c
12109 * support/Util/SDCCerr.h
12112 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

12115 * src/SDCCicode.c (operandOperation): rewritten some ops
12116 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
12117 * src/SDCCsymt.c (computeType): literals are handled the same way as any
12119 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
12120 be re-activated by defining REDUCE_LITERALS)
12121 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
12122 unsigned, but are signed by default
12123 * src/SDCCval.c (constVal): rearranged
12124 * src/SDCCval.c (valMod): preliminary fix
12125 * src/SDCCval.c (valCastLiteral): use TYPE_* types

12165 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
12166 * src/SDCCval.c (constVal): changed default to signed; hex and octal
12167 constants are unsigned; added recognition of "u" flag for unsigned
12168 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
12169 * src/SDCCval.c (valDiv, valMod): fixed signdness

12632 messages from optionsTable when a port is not configured, added
12633 support for the PIc16 port in the ports table, when executing
12634 the compiler with no port specified on command line, a default
12635 port is selected with the new macro DEFAULT_PORT which is
12636 defined in port.h, in setDefaultOptions() linkOptions is removed
12637 from initialization assignment, since now it is a set,
12638 parseCmdLine uses setParseWithComma for linkOptions, in
12639 linkEdit() linkOptions are accessed with new function indexSet()
12640 which returns the i'th item of a set variable. See SDCCset.c, in
12641 linkEdit() when calling buildCmdLine(), added linkOptions as
12642 last argument. Now users can pass arguments to gplink via the
12643 -Wl option, main() uses pic16glue() to glue up pic16 programs

12657 gpasm complaining and test the linkage with gplink, _linkCmd and
12658 _asmCmd changed to be more gplink and gpasm friendly
12659 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12660 produced an error when parsed, peep rule 12 is added to utilize
12661 movff, but it is commented out since the pCode does not support
12662 yet a command with 2 address arguments
12664 2003-05-18 <johan AT balder>
12666 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

13688 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
13689 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
13690 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
13691 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

13701 * src/SDCCicode.c: fixed array add
13703 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
13704 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
13705 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
13707 2003-01-04 <johan AT balder>
13709 * src/SDCCval.c (getNelements): fixed the initialized array of structures
13711 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13712 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
13714 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
13715 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

13721 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
13722 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
13724 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13725 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13727 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13729 * in /sdcc/as/mcs51/ changed these files in order to create an
13730 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13731 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13732 following files to include the previous two files: aslink.dsp,
13733 Makefile.aslink, Makefile.bcc, and Makefile.in.
13735 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13736 .adb instead of .cdb
13738 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13740 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13741 value from option --iram-size.
13743 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13745 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13748 2002-09-18 <wiml AT hhhh.org>
13750 * SDCClrange.h: exposed setFromRange() and setToRange()
13751 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13752 packRegsForAccUse() (bug 542397)
13753 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13754 multiple times and emitting the fetch operations more than once
13755 added aopGetUsesAcc() function to allow binary operators to
13756 fetch their operands in the correct order; made genMinus() emit
13757 compact code for X = LITERAL - Y
13759 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13760 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13761 sprintf() in line 1267.
13763 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13764 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13767 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13768 Changes to aslink (All the changes are marked with 'JCF'):
13770 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13773 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13774 area BSEG. Also moves, if possible, the DATA area down into the internal
13775 ram so more space is available.
13777 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13780 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13781 not bytes. Function summary() which creates a memory usage summary
13782 file with extension .mem. Reports of overlaping stack and small stack
13783 size. If the space for the stack is less than 16 bytes aslink trows a
13786 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13787 the 8051. Option 'y' for memory summary output file.
13789 Changes to sdcc (All the changes are marked with 'JCF'):
13791 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13793 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13794 overlaying area for it (uses RegBankUsed[4]).
13796 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13797 bank zero as used by default. By default aslink locates the stack
13798 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13799 the creation of the .mem file. Delegates the allocation of data area
13800 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13801 the begining of the stack area to aslink.
13803 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13804 glue() in SDCCglue.c creates an area for it.
13806 2002-09-03 Borut Razem <borut.razem AT siol.net>
13807 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13808 sdcc/src/pic/glue.c:
13809 introduced atexit() handler for teporay files removal in case of
13810 errors, assertions, ...
13812 2002-08-29 Borut Razem <borut.razem AT siol.net>
13813 * sdcc/support/cpp2/auto-host_vc_in.h:
13814 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13815 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13816 Maybe there is a similar problem with BORLANDC? It should be checked!
13818 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13819 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13820 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13821 was not executed, and the compiler (cl) launched a warning:
13822 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13824 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13825 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13827 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13828 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13830 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13831 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13832 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13833 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13834 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13835 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13836 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13837 - added Release configuration in VS projects
13838 - review of compiler an linker options
13839 - VC .exe files are generated in bin_vc directory, not to interfere
13840 with binaries generated from other projects (cygwin, mingw, bcc ...)
13842 * sdcc/src/yacc.dsp: added
13844 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13845 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13846 and insert the version number definitions from .version
13848 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13850 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13851 added - genarate auto-host.h using auto-host_vc_in.h as template
13854 removed from CVS, generated automatically
13856 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13857 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13859 2002-08-11 Borut Razem <borut.razem AT siol.net>
13860 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13862 2002-08-10 Borut Razem <borut.razem AT siol.net>
13863 * src/SDCCmain.c (main):
13864 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13865 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13866 The consequence was that some temporary files were not removed.
13869 unification of code in functions tempfilename() and tempfile():
13870 function tempnam() is defined in Visual Studio 6.0 and .NET
13872 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13874 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13875 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13876 - removed compiler command line option /WX: Treats all warnings as errors
13877 - update a list of source files, included into the project
13879 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13880 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13881 changed project type to Generic Project so that can be correcly converted to VS.NET project
13883 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13885 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13887 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13889 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13890 added return 0 statements after assert() to make compiler happy
13892 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13893 added newline in the def file to keep MSC compiler satisfied
13895 * sdcc/src/z80/gen.c:
13896 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13897 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13898 - solved MSC error in function aopDump()
13900 * sdcc_vc.h: define PREFIX as "\\sdcc"
13902 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13903 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13905 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13906 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13907 - Rewrote the register banking algorithm.
13908 - Added pCode live-range analysis to registers (for now, only non-used and
13909 singly-used registers optimized away)
13911 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13913 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

13936 * src/z80/main.c: Added force callee saves for jaune.
13938 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13940 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13942 2002-03-28 Johan Knol <johan AT balder>
13944 * src/SDCCval.c: fixed bug #532436
13946 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13948 Added "char *Processor" field to the port structure.
13951 Added -p option. Allows port dependent processor to be specified.
13954 Initialized the new field char *Processor field to NULL in all ports
13957 Compiler generated registers for interrupt context saving
13958 were not getting allocated.
13960 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13963 Fixed left shift. Will promote the left side of a left shift
13964 if a) left shifting more than size of operand or b) when assigned
13965 to something size > size of left side
13967 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13969 tons of changes. Register allocation has been
13970 rewritten. Added customization for the various PICs. Flow
13971 analysis is restructured. ...
13973 * src/pic/device.h:
13976 * src/pic/device.c:
13977 Added. device.c is a PIC port hack to accomodate variations
13980 2002-03-13 Michael Hope <michaelh AT vroom>
13982 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13984 2002-03-04 johanknol <johanknol AT manik>
13986 * /src/SDCCval.c: fixed
13988 const unsigned char arr[][2] = { { 0, 1 } };
13989 t18.c:1: error: Initializer element is not constant

14075 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
14077 * sdcc/src/SDCCloop.c:
14078 Previous fix was not good. basic blocks that have "break" or "return" are
14079 not really partof a loop , but live ranges used in these blocks should
14080 be live thru the entire loop, so set partOfLoop but don't add them to
14083 2002-02-21 <johan AT FRIJA>
14085 * src/SDCCcse.c: fixed bug #514308
14087 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
14090 Fixed BUG #519583. If a conditional block ended in a return/break
14091 statement inside a loop, it was not being considered part of the loop.
14093 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
14095 2002-02-10 Karl Bongers <karl AT turbobit.com>

14101 * device/examples/test2.c:
14102 Fix bug, "red" variable not being initialized(compiler complained).
14104 * device/examples/Makefile, examples/test3.c:
14105 Add Makefile in device/examples folder, compiles test3.c
