862 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
864 Enabled VPATH feature: changed nearly all Makefiles (149 files).
865 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
867 One basic decision: e.g. src/clean.mk includes further files. In order
868 to make this work there are two solutions:
869 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
870 run configure on them. This way they can use
871 'include $(srcdir)/port-clean.mk'
872 - always include clean.mk by the Makefile at the same level. To avoid
873 that `make clean` tries to include and build Makefile.dep the
874 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
875 implemented, because now even `make uninstall` doesn't create
876 Makefile.in. clean.mk could be eliminated by pasting it in
879 * debugger/mcs51/Makefile.in: build own objects from library sources
880 (SLIB, SDCC) in current directory
882 * configure, configure.in: renamed --disable-device-lib-build in
883 --disable-device-lib; added --enable-doc, the required tools are
884 searched by configure; added result message; the toolchain for the
885 belonging ports are now only built, if the port is enabled.
887 * support/regression/*: all output is written in directory gen, because
888 the fwk and ports directories don't livet in the build tree using vpath
890 * doc/sdccman.lyx: renamed --disable-device-lib-build to
891 --disable-device-lib, added --enable-doc, added section VPATH
893 * sim/ucsim/configure.in,
894 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
895 z80 are enabled by default
897 2006-04-24 Raphael Neider <rneider AT web.de>
899 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
900 to config word, "pic14_"-prefixed some extern functions
901 (pic14_emitConfigWord): emit __config directive(s) if assignment to
902 config word has been found
903 * src/pic/device.h: added prototypes
904 * src/pic/pcode.c: added "pic14_"-prefix where needed
905 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
907 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
909 (pic14emitRegularMap): ignore config words,
910 (pic14createInterruptVect): moved generating __config directives away
911 (picglue): have __config directives emitted
913 2006-04-24 Borut Razem <borut.razem AT siol.net>
915 * doc/Makefile: sync with nightly build makefile

921 fixes #1469504 and #1474602,
922 (pCodeRegOptimizeRegUsage): fixed typo in comment
924 2006-04-24 Borut Razem <borut.razem AT siol.net>
926 * device/examples/main8051.c: deleted - it was removed from CVS
927 24.mar.2000 and after that modified 18.feb.2001, so it reappered
928 after the transition to Subversion
929 * src/SDCCalloc.h: deleted - it was removed from CVS
930 3.feb.2001 and after that modified 18.feb.2001, so it reappered
931 after the transition to Subversion

1169 interrupts need an interrupt number now if they are made critical),
1170 and enabled nesting of critical functions though not for gbz80
1171 (genCritical, genEndCritical): added functions
1172 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1173 * src/z80/mappings.i: added "ei" to all mappings

1185 the left operand is shorter than the result (c* = lit-c* + int),
1187 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1190 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1192 * src/.version: increased version number to 2.5.5
1193 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1194 linking is done manually in pic16 port's _linkEdit,
1195 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1196 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1197 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1198 allocate asmop as AOP_ACC,
1199 (aopForRemat): added parameter 'bool result' in function declaration,
1200 (pic16_aopGet): return AOP_ACC when accessing WREG,
1201 (pic16_popGetTempReg): minor modification,

1212 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1213 call to allocReg, not by manually allocating a new one,
1214 (pic16_assignRegisters): now before going through the register
1215 allocating functions mark all registers as free. This eliminates some
1216 side effects resulting from peephole parser done earlier in the backbone
1218 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1276 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1277 which dumps before the function entry point a data byte which represents
1278 the number of the local variables used by the specified function, added
1279 'xinst' for initial support for Extended Instruction Support,
1280 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1281 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1282 port->fun_prefix anymore (may change later),
1283 (genFunction, genEndFunction): do not store/restore local registers for
1284 _main (this should take care the --main-return command line option in
1286 (genOr): removed some legacy pic-port instructions,
1287 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1288 performing operations with SFR's causes data to be written more than
1289 once to each SFR. Perhaps SFRs should be handled in special cases...
1290 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1292 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1293 into account for stack starting position,

1295 --extended or -y for Extended Instruction Support,
1296 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1297 (deassignLRs): *** perhaps the most important change, old 'for' code
1298 (commented out for reference), didn't account for some registers which
1299 were left marked 'not free' after a pointer operation. The change
1300 reduces register usage a lot in some cases
1302 2006-03-04 Borut Razem <borut.razem AT siol.net>

3577 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3578 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3579 always available in leading double underscore form. The C99 support is
3580 mostly missing, but it's a start.
3581 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3662 * device/lib/printf_large.c: removed inline assembly for portability and
3663 readability. Use printf_fast if speed or size are more important.
3664 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3665 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3667 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3669 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3670 prevent compiler warning
3672 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3674 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3675 moved to level 0 and declared as static. Also they are explicit
3676 placed in access bank. This was necessery because some times they
3677 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3678 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3679 optimizations. Currently only compare to unsigned char is implemented,
3680 * src/pic16/gen.c: added fReturnIdx array,
3681 * (struct resolvedIfx) is moved to gen.h and made public,
3682 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3683 * (aopForSym): added an optimization to directly store in stack of
3684 the operand of a SEND iCode,
3685 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3686 but as registers instead (AOP_REG) using the fReturnIdx array,
3687 * (pic16_freeAsmop): remove the freed register from the
3688 _G.sregsAlloc field,
3689 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3690 a compare of 'WREG',
3691 * (pic16_popGetTempRegCond): changed function prototype, now
3692 function takes also a bitVector argument v which holds the current
3693 set of registers that are allocated for stack access by aopForSym,
3694 registers allocated in aopForSym for accessing stack symbols are not
3695 any more part of the functions usedRegs field,
3696 * (genCall): some times aopOp is called for a stack variable to be
3697 send, aopForSym might perform the push, if this is true make sure
3698 that genCall doesn't push the variable twice by testing _G.resDirect,
3699 * (genFunction): changed testing for unspecified interrupt number
3700 from 256 to INTNO_UNSPEC,
3701 * modified selection scheme of frame pointer generation. Previously
3702 if function did use local registers a frame pointer was generated,
3703 now a frame pointer is generated only if function has arguments
3704 (that need PLUSW2 register access), or has stack arguments, or the
3705 compiler is not instructed to omit the frame pointer,
3706 * (genEndFunction): before restoring local registers that were saved
3707 in the function preamble, also restore the registers that *might*
3708 have been allocated for stack access,
3709 * (genRet): removed some old comments,
3710 * (genCmp, the active (RN's) version): added a call to the
3711 pic16_genCmp_special function to perform the compare with a more
3712 robust and optimized way,
3713 * (genInline): a feature has been added in inline code generation,
3714 which allows a wildcard variable substitution when writing inline
3715 assembly. Code is incomplete and experimental therefore undocumented,
3716 * (genCast): changed order of aopOp for result and right to allow
3717 aopForSym to directly load the result if possible,
3718 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3719 perform an optimized compare on some selected special occasions,
3720 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3721 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3722 generate an IVT any more,
3723 * src/pic16/main.c (pic16_optionsTable): added command line option
3725 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3726 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3728 * src/pic16/NOTES: Raphael Neider added in list of active developers
3729 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3730 jumptable_end to prevent bug #,
3731 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3732 inCond and outCond fields,
3733 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3734 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3735 turn off register spilling,
3736 * (packRegsForOneUse): synced with other ports' versions although it
3737 is not used currently,
3738 * (pic16_packRegisters): added an optimization while reading
3739 structure bitfields, some registers may be saved (malloc code is
3740 decreased by 80 bytes)
3742 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3744 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3745 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3746 this can be optimized more?
3748 2005-03-10 Raphael Neider <rneider AT web.de>
3750 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3751 genNearPointerGet): (hopefully) fixed access to bitfields via
3752 pointers (p->bitN = x; and x = p->bitN; failed)

4386 Adding support for replacing ljmps with sjmps in jumptables
4387 generated for switch statements. For now you need to set the
4388 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4389 Now 4 algorithms for mcs51 jumptable generation are used:
4390 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4391 addresses loaded pc-relative for up to 112 cases and stack-pushing
4392 target addresses loaded with offset from dptr for up to 256 cases.

4419 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4420 to call when a stack overflow occurs,
4421 * (malloc.h): added CVS Id tag,
4422 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4424 * added libc directory. The current version of LibC contains string
4425 functions, ctype functions and macros and some functions of the
4426 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4427 be extensively tested in the future. Standard disclaimer here.
4428 Library is not automatically build yet. But one can build it by
4429 invoking 'make' inside the libc directory.
4430 * added ADC library under libio. Preliminary version yet.
4432 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4439 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4440 * (pic16_storeForReturn): optimized return of 0,
4441 * (genCmp): experimental code for new genCmp which uses PIC18's
4442 special compare&skip instructions. Initial tests fail some times
4443 with variables grater than 1 byte in size, so new code is disabled,
4444 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4446 * (genCast): began a fix to optimize the casting of a bit to another
4447 bit, now assigning a bitfield to another bitfield will fail, sorry,
4448 * src/pic16/main.c: disabled the use of lr-support feature,
4449 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4452 bits with offset (case PO_GPR_BIT),
4453 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4455 * (isBankInstruction): modified to return 0 for no banking instruction,
4456 and 1 for banking instruction,
4457 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4458 caused stop processing pCodes after a inline assembly block,
4459 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4460 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4461 registers when it shouldn't,
4462 * src/pic16/ralloc.c (allocReg): add preliminary support for
4463 supporting a limited set of temporary registers,
4465 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4467 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4468 genDataPointerSet): ensure assignments always copy in MSB to LSB
4470 (loadRegFromAop): recognize CLRH optimization,
4471 (genFunction): optimize RECEIVE iCodes in reentrant functions
4473 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4475 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4489 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4491 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7437 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7440 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7441 strtof is not part of C89 and isn't included with Mac OS X.
7443 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7447 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY
7448 (genMultOneByte): fixed bug in signed vs unsigned multiplication
7449 * sim/ucsim/hc08.src/inst.cc (inst_clr): added missing effective
7450 address fetch for clr instruction

7467 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
7470 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7472 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7473 loaded with the linker search paths (-L arguments) and the libraries
7474 to be linked with the current source (-l arguments). Changes
7475 currently will affect only the pic16 port.
7476 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7477 include path the port specific paths and port specific libraries,
7478 * gplink command now contains the $3 argument,
7479 * src/pic16/device.h,
7480 * src/pic16/device.c,: structure PIC_device is made public and
7481 renamed to PIC16_device, the same for variable Pics which is renamed
7482 to Pics16. Updated all references to them.
7483 * src/pic16/glue.c (pic16glue): corrected bug with code
7484 initialization which bypassed the variable initializations block.
7486 * device/lib/pic16/Makefile.rules: removed --penable-stack from

7494 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7496 Documenting changes from previous commits.
7497 * configure.in (version 1.56),
7498 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7499 when generating output files to configure the pic16 library,
7500 but now I've commented it out, since gputils aren't installed in the
7501 SF compile farm, so library won't compile
7503 * device/lib/Makefile.in (version 1.56): initially I've added in
7504 target 'all' the prerequestive 'model-pic16' so it compiled the
7505 pic16 library, but now I've commented it out for the same reasons
7507 * added targets 'model-pic16' and 'objects-pic16' to compile the
7509 * added target 'port-specific-objects-pic16' to handle the
7510 generated libraries and copy them into the build/ directory
7511 * added target 'clean-intermediate-pic16' to clean intermediate
7512 files into pic16 directory
7513 * in target 'installdirs' added line to create directory pic16 in
7514 the installation path
7516 * device/include/Makefile.in (version 1.11): in target 'install'
7517 added lines to copy all header files to installation path,
7518 * in target 'installdirs' added line create directory for pic16
7519 headers in the installation path
7521 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7534 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7535 option so that it actually works. Made it specific to the z80, since
7536 the gbz80 doesn't have these kinds of I/O ports.
7538 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7540 * device/include/z180.h,

7553 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7555 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7556 changed interrupt vector table generation to only emit declared vectors.
7557 * device/include/Makefile.in: added missing backslash
7558 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7560 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7562 Mainly changes to support compilation of the device libraries
7563 * src/pic16/device.c: stack is allocated via symbol and not
7564 via literal number. The symbol is placed in the corresponding
7565 position of the data ram
7566 * (pic16_dump_section): relocatable and absolute uninitialized
7567 data are now emitted in sorted order to reduce section naming,
7568 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7569 weren't marked as being in the access bank,
7571 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7573 Added portion of GNU PIC Library under the directory
7574 device/include/pic16 and device/lib/pic16. These files
7575 contain the declarations of SFRs for the PIC18Fxx2 devices.
7576 The directory is initialized via configure from toplevel.
7578 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7580 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7581 the spilllocations to be compared correctly
7583 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7585 * src/SDCCast.c (decorateType): fixed bug introduced today
7587 2004-01-12 Borut Razem <borut.razem AT siol.net>
7589 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7592 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7594 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7595 in simpler and even better code
7597 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7599 * src/SDCCicode.c (operandOperation): fixed bug #874819

7603 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7605 * doc/sdccman.lyx: Moved and added some sections, small changes
7606 all over. Telling LaTeX to be less strict with word spacing
7607 to better keep the right margin. Changed some notes about
7608 maintainance of the ports in section 3.2.1 - is it OK like this?
7610 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7612 SDCC source changes:
7613 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7646 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7647 UPPER for immediate operands,
7648 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7650 * src/pic16/peeph.def: all peepholes with movff are commented out,
7651 because there is a problem in the pcode peep optimizer,
7652 * src/pic16/ralloc.c: the register allocator can now reuse local
7653 function symbols for another function. This saves register usage.
7654 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7656 Added file src/pic16/NOTES with information about program writing on
7657 the current port version.

7666 * src/SDCCmain.c : fixed #872250: -l command line defined library
7667 files are scanned before standard library files
7669 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7683 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7685 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
7686 gen51Code): more efficient parameter receive for --model-large
7689 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7692 * src/z80/main.c: added missed needLinkerScript flags (more than
7693 one port structure defined in these file)
7694 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
7697 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

7710 needLinkerScript flag
7712 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7713 * src/pic/glue.c: added variable udata_section_name to
7714 override default uninitialized data segment definition for
7715 devices only with SHAREBANK memory (reported from Erik Epetrich)
7716 * (pic14emitOverlay): modified to emit a commented overlay segment
7717 directive when no overlay data exist
7718 * (picglue): modified to emit uninitialized data segment
7719 according to udata_section_name

7724 arguments via -W option
7725 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7726 object file from '.rel' to '.o' in port->linker structure,
7727 changed size of fptr from 2 to 3 in port structure
7729 2004-01-07 Borut Razem <borut.razem AT siol.net>
7731 * support/scripts/sdcc.nsi: update PATH
7732 * support/scripts/sdcc.ico: craeted
7734 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
7736 * device/include/Makefile.in: fix install
7737 * doc/Makefile: fix install
7739 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7741 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7743 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
7744 how the function variable allocation summary is displayed; also
7745 include information about variables allocated to the overlay
7748 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7750 * as/mcs51/lkmain.c: Help about -Y option

7760 LEFT_OP (left shift)
7762 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7764 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7765 (default behaviour).
7767 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7769 A python script to validate compiler diagnostic messages. It can be
7770 used to verify that sdcc complains about bad c source code and
7771 gives a good location of the error.
7772 * support/valdiag/Makefile,
7773 * support/valdiag/valdiag.py,
7774 * support/valdiag/tests/*
7776 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7778 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7779 * src/SDCCsymt.c (newEnumType),

7787 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7789 * src/common.h: added ifndef/define/endif macros
7790 around the header file.
7791 Bug reported from Jesus Calvino-Fraga
7793 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7795 * sdcc.spec: updated
7796 * device/include/Makefile.in: don't install CVS directories
7797 * device/lib/Makefile.in: added removal of CVS directories after install
7798 * doc/Makefile: fixed install, added local_icons
7799 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7800 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7801 * src/ds390/gen.c (genRightShift): fixed bug #870788
7802 * src/SDCCast.c (decorateType): fixed bug #870781
7804 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7806 PIC16 port related changes:
7807 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7808 added variable stackPos,
7810 * gen.c: genCall, assignResultValue: added support for
7811 pushing/retrieving function parameters to/from stack,
7812 genFunction,genEndFunction: setup stack frame for the
7814 genAddrOf: will be changed according to bug 863624
7816 * added files genutils.c and genutils.h which contain gen*
7817 debugged and optimised functions extracted from gen.c
7819 * glue.c: added variable 'externs' which holds extern symbols,
7820 pic16emitRegularMap: is modified to properly handle relocatable
7821 symbols under the new scheme,
7822 pic16createInterruptVect: is modified
7823 pic16printPublics: is modified to emit 'global' assembler directives,
7824 added pic16_printExterns to print extern symbols,
7825 pic16glue: initializes stack/frame pointer in the beginning of
7826 the assembly output. Temporary hack, will be corrected later,
7827 because gplink yet does not support stack and SDCC does not
7828 yet support a type of crt0.o object to create the final binary.
7830 * Removed many lines that contain 8051 legacy code.
7831 * The code is finally placed under a 'code' directive.
7832 * Added port specific options.
7834 * _process_pragma: simplified since now we do not need *special*
7835 include file to define SFR registers. But a separate header
7836 will be needed. This will be developed later.
7837 * _pic16_parseOptions: added, parses port specific options:
7838 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7839 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7840 --preplace-udata-with=
7842 * _pic16_setDefaultOptions: modified to initialize section names,
7843 but hack is temporarly out of order since it needs improvement.
7844 * _pic16_genAssemblerPreamble: configuration words are emitted by
7845 their address instead of their name. This part is incomplete and
7846 supports only the 18Fxx2 devices. Other devices will emit an error
7847 during assembly since they do not contain the same set of config
7849 * _pic16_genIVT: is modified,
7851 * pcode.c: added definitions for some hardware registers that are needed
7853 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7854 All PCI entries are updated. Now LFSR is supported.
7855 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7856 * added pic16_newpCodeOpLit2 to support instructions with
7857 two literal arguments
7858 * pic16_pCode2str: corrected code that emits assembler instructions
7859 with two literal operands and those that have an access bit modifier
7860 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7861 this fixes a bug which caused some labels to be lost, when an
7862 assembler directive was added, i.e. banksel,
7863 * pic16_FixRegisterBanking: improved logic that causes the insertion
7865 * InlineFunction: functions that are called once, are not any more
7866 inlined. This can be a port option in the future,
7868 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7870 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7871 hold the corresponding uninitialized symbols,
7872 * pic16_allocProcessorRegister: registers have explicit marked the
7874 * pic16_allocInternalRegister: registers are explicit marked as
7876 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7877 processing list, so bit registers were lost,
7880 * ralloc.h: added field 'accessBank' and original symbol operand
7881 in register definition,
7882 * removed the field isMapped from register definition,
7884 ** Several functions have been removed from various sources:
7885 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7886 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7887 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7888 pic16_assignRelocatableRegisters
7890 ** others have been introduced:
7891 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7892 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7894 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7896 * support/scripts/inc2h.pl: changed definition of BIT_AT
7897 to emit 'sbit at' instead of 'bit at'. This was a request.
7899 PIC16 port related preliminary changes:
7900 * gen.c: prefixed function popRegFromString with
7901 pic16_ and all references to it corrected
7902 * pcode.c: all pic16_pc_* hardware registers prefixed
7903 with underscore (_),
7904 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7905 * ralloc.c: newReg(): when register is REG_SFR then
7906 set address to rIdx,
7907 pic16_allocProcessorRegister(): marks register wasUsed=0
7908 pic16_writeUsedRegs(): added a call to assign processor
7909 registers via pic16_assignFixedRegisters
7911 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7913 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7914 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7915 variables in unused register banks. Also the SSEG is placed
7916 wherever there is enough space for it, and IDATA can be anywhere
7917 in internal RAM. For now compile using -Wl-Y[stack_size].
7918 The mem file is different for this option as well, since it
7919 makes no sense of talking about DSEG lenght.
7921 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7923 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8923 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8924 before instructions that use the _STATUS register
8926 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8928 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8929 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8930 fetching of the pointer
8931 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8932 copied from genNearPointerSet()
8933 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8934 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8935 If they pop r0/r1 they must be called in the opposite order than aopOp().
8936 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8937 (resp. --stack-auto), prepared for --xstack

8946 these ports have their own __sdcc_external_start()
8948 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8950 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8951 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8952 type for bits was changed. It resulted in bit variables becoming
8953 global, which is not permitted in PIC 14 assembly output.
8955 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8957 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8959 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8961 Z80 and MCS51 linkers complaint if a public symbol is defined

8970 A few small changes that speed up the peephole optimizer.
8974 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8976 Try to make the peephole optimizer smarter by maintaining
8977 an association between the assembly source code and the
8978 iCodes that originated them. Put this information to use
8979 with a new peephole rule condition "notVolatile" so that
8980 the rules can be aggressive yet still safe.
8985 * src/mcs51/peeph.def
8987 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8991 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8992 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8993 if the left or right operand symbols have the accuse flag set.
8995 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8997 Changed the type of the result of the ! (NOT) operator to char;
8998 previously it returned the same type as the source. This allows
8999 us to eliminate all the genFloatNot functions (all of its target
9000 implementations were very buggy) since !float can use the same
9003 * src/SDCCicode.c (ast2iCode): ! returns char

9012 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9013 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9014 during interrupts. Ensure WSAVE is located at a shared bank address.
9015 2. Fixed page selection in some places
9016 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9017 the registers name strings.
9018 4. Fixed "signed / unsigned compare" compiler warnings.
9019 5. The PIC port manages its own allocation of the general purpose
9020 registers, but makes no attempt to reuse them. As a result when
9021 compiling it soon runs out of general purpose registers. Some
9022 additional code was added to the files pcode.c and device.c to walk
9023 through the function call tree and rename the registers so that they
9033 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9034 genPlus() & genMinus() when the result is the same as left or right

9040 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9042 Made bitfield a distinct type from bit so that bitfields
9043 convert as per ANSI C and bits retain their traditional
9044 boolean style behaviour. Implemented bitfield support in
9052 * src/ds390/gen.c: bit v bitfield split
9053 * src/z80/gen.c: New support for bitfields
9054 * support/regression/tests/bitfields.c: reenabled z80,
9057 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9059 Rules 246.x, 247.x relate to bitfields, the others speed up
9060 access to xdata mapped I/O devices.
9062 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9064 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9066 Cleaned up genPackBits and genUnpackBits and added two helper
9067 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9068 for literal assignments in genPackBits (thanks to Frieder for
9074 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9076 Fixed bug #748310 (pointer to function type mishandled when the
9077 function name is omitted). Also fixed a SIGSEGV when a function
9078 attribute (reentrant, etc) is used on a non-function or on a
9079 function but misplaced before the parameter list.
9081 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9083 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9106 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9108 Made the constant following the "interrupt" keyword optional. If
9109 omitted, the function will not automatically be given an entry
9110 in the interrupt vector table (similar to #pragma NOIV, but
9111 less syntacticly kludgy). The interrupt number is also now
9112 range checked. Also fixed a bug in the high order bit example

9126 * src/SDCCicode.c (operandOperation): rewritten some ops
9127 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9128 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9130 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9131 be re-activated by defining REDUCE_LITERALS)
9132 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9133 unsigned, but are signed by default
9134 * src/SDCCval.c (constVal): rearranged
9135 * src/SDCCval.c (valMod): preliminary fix
9136 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9641 * src/SDCCmain.c: linkOptions is changed to set *,
9642 added if/endif conditional macros to remove options help
9643 messages from optionsTable when a port is not configured, added
9644 support for the PIc16 port in the ports table, when executing
9645 the compiler with no port specified on command line, a default
9646 port is selected with the new macro DEFAULT_PORT which is
9647 defined in port.h, in setDefaultOptions() linkOptions is removed
9648 from initialization assignment, since now it is a set,
9649 parseCmdLine uses setParseWithComma for linkOptions, in
9650 linkEdit() linkOptions are accessed with new function indexSet()
9651 which returns the i'th item of a set variable. See SDCCset.c, in
9652 linkEdit() when calling buildCmdLine(), added linkOptions as
9653 last argument. Now users can pass arguments to gplink via the
9654 -Wl option, main() uses pic16glue() to glue up pic16 programs

9666 * src/pic16/glue.c: commented out some error producing lines
9667 * src/pic16/main.c: __config directives are commented out to stop
9668 gpasm complaining and test the linkage with gplink, _linkCmd and
9669 _asmCmd changed to be more gplink and gpasm friendly
9670 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9671 produced an error when parsed, peep rule 12 is added to utilize
9672 movff, but it is commented out since the pCode does not support
9673 yet a command with 2 address arguments
9675 2003-05-18 <johan AT balder>
9677 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9704 2003-05-11 Borut Razem <borut.razem AT siol.net>
9706 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9707 the path of bin directory, so that PATH is the only env. variable, which has to be set

10742 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10743 following files to include the previous two files: aslink.dsp,
10744 Makefile.aslink, Makefile.bcc, and Makefile.in.
10746 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10747 .adb instead of .cdb
10749 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10751 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the

10763 packRegsForAccUse() (bug 542397)
10764 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10765 multiple times and emitting the fetch operations more than once
10766 added aopGetUsesAcc() function to allow binary operators to
10767 fetch their operands in the correct order; made genMinus() emit
10768 compact code for X = LITERAL - Y

10778 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10779 Changes to aslink (All the changes are marked with 'JCF'):
10781 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10784 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10785 area BSEG. Also moves, if possible, the DATA area down into the internal
10786 ram so more space is available.
10788 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10791 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10792 not bytes. Function summary() which creates a memory usage summary
10793 file with extension .mem. Reports of overlaping stack and small stack
10794 size. If the space for the stack is less than 16 bytes aslink trows a
10797 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10798 the 8051. Option 'y' for memory summary output file.
10800 Changes to sdcc (All the changes are marked with 'JCF'):
10802 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10804 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10805 overlaying area for it (uses RegBankUsed[4]).
10807 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10808 bank zero as used by default. By default aslink locates the stack
10809 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10810 the creation of the .mem file. Delegates the allocation of data area
10811 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10812 the begining of the stack area to aslink.
10814 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10815 glue() in SDCCglue.c creates an area for it.
10817 2002-09-03 Borut Razem <borut.razem AT siol.net>
10818 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10819 sdcc/src/pic/glue.c:
10820 introduced atexit() handler for teporay files removal in case of
10821 errors, assertions, ...
10823 2002-08-29 Borut Razem <borut.razem AT siol.net>
10824 * sdcc/support/cpp2/auto-host_vc_in.h:
10825 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10826 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10827 Maybe there is a similar problem with BORLANDC? It should be checked!
10829 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10830 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10831 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10832 was not executed, and the compiler (cl) launched a warning:
10833 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10835 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10836 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10838 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10839 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10841 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10842 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10843 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10844 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10845 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10846 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10847 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10848 - added Release configuration in VS projects
10849 - review of compiler an linker options
10850 - VC .exe files are generated in bin_vc directory, not to interfere
10851 with binaries generated from other projects (cygwin, mingw, bcc ...)
10853 * sdcc/src/yacc.dsp: added
10855 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10856 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10857 and insert the version number definitions from .version
10859 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10861 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10862 added - genarate auto-host.h using auto-host_vc_in.h as template
10865 removed from CVS, generated automatically
10867 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10868 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10870 2002-08-11 Borut Razem <borut.razem AT siol.net>
10871 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10873 2002-08-10 Borut Razem <borut.razem AT siol.net>
10874 * src/SDCCmain.c (main):
10875 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10876 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10877 The consequence was that some temporary files were not removed.
10880 unification of code in functions tempfilename() and tempfile():
10881 function tempnam() is defined in Visual Studio 6.0 and .NET
10883 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10885 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10886 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10887 - removed compiler command line option /WX: Treats all warnings as errors
10888 - update a list of source files, included into the project
10890 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10891 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10892 changed project type to Generic Project so that can be correcly converted to VS.NET project
10894 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10896 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10898 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10900 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10901 added return 0 statements after assert() to make compiler happy
10903 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10904 added newline in the def file to keep MSC compiler satisfied
10906 * sdcc/src/z80/gen.c:
10907 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10908 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10909 - solved MSC error in function aopDump()
10911 * sdcc_vc.h: define PREFIX as "\\sdcc"
10913 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10914 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11086 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11088 * sdcc/src/SDCCloop.c:
11089 Previous fix was not good. basic blocks that have "break" or "return" are
11090 not really partof a loop , but live ranges used in these blocks should
11091 be live thru the entire loop, so set partOfLoop but don't add them to
11094 2002-02-21 <johan AT FRIJA>
11096 * src/SDCCcse.c: fixed bug #514308
11098 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
