812 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
814 Enabled VPATH feature: changed nearly all Makefiles (149 files).
815 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
817 One basic decision: e.g. src/clean.mk includes further files. In order
818 to make this work there are two solutions:
819 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
820 run configure on them. This way they can use
821 'include $(srcdir)/port-clean.mk'
822 - always include clean.mk by the Makefile at the same level. To avoid
823 that `make clean` tries to include and build Makefile.dep the
824 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
825 implemented, because now even `make uninstall` doesn't create
826 Makefile.in. clean.mk could be eliminated by pasting it in
829 * debugger/mcs51/Makefile.in: build own objects from library sources
830 (SLIB, SDCC) in current directory
832 * configure, configure.in: renamed --disable-device-lib-build in
833 --disable-device-lib; added --enable-doc, the required tools are
834 searched by configure; added result message; the toolchain for the
835 belonging ports are now only built, if the port is enabled.
837 * support/regression/*: all output is written in directory gen, because
838 the fwk and ports directories don't livet in the build tree using vpath
840 * doc/sdccman.lyx: renamed --disable-device-lib-build to
841 --disable-device-lib, added --enable-doc, added section VPATH
843 * sim/ucsim/configure.in,
844 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
845 z80 are enabled by default
847 2006-04-24 Raphael Neider <rneider AT web.de>
849 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
850 to config word, "pic14_"-prefixed some extern functions
851 (pic14_emitConfigWord): emit __config directive(s) if assignment to
852 config word has been found
853 * src/pic/device.h: added prototypes
854 * src/pic/pcode.c: added "pic14_"-prefix where needed

860 (pic14createInterruptVect): moved generating __config directives away

871 fixes #1469504 and #1474602,
872 (pCodeRegOptimizeRegUsage): fixed typo in comment
874 2006-04-24 Borut Razem <borut.razem AT siol.net>
876 * device/examples/main8051.c: deleted - it was removed from CVS
877 24.mar.2000 and after that modified 18.feb.2001, so it reappered

879 * src/SDCCalloc.h: deleted - it was removed from CVS

1118 implemented patch 1120823 Thanks to Willy De la Court (normal
1119 interrupts need an interrupt number now if they are made critical),
1120 and enabled nesting of critical functions though not for gbz80
1121 (genCritical, genEndCritical): added functions
1122 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1123 * src/z80/mappings.i: added "ei" to all mappings

1135 the left operand is shorter than the result (c* = lit-c* + int),
1137 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1140 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1142 * src/.version: increased version number to 2.5.5
1143 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1144 linking is done manually in pic16 port's _linkEdit,
1145 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1146 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1147 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1148 allocate asmop as AOP_ACC,
1149 (aopForRemat): added parameter 'bool result' in function declaration,
1150 (pic16_aopGet): return AOP_ACC when accessing WREG,
1151 (pic16_popGetTempReg): minor modification,

1162 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1163 call to allocReg, not by manually allocating a new one,
1164 (pic16_assignRegisters): now before going through the register
1165 allocating functions mark all registers as free. This eliminates some
1166 side effects resulting from peephole parser done earlier in the backbone
1168 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1226 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1227 which dumps before the function entry point a data byte which represents
1228 the number of the local variables used by the specified function, added
1229 'xinst' for initial support for Extended Instruction Support,
1230 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1231 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1232 port->fun_prefix anymore (may change later),
1233 (genFunction, genEndFunction): do not store/restore local registers for
1234 _main (this should take care the --main-return command line option in
1236 (genOr): removed some legacy pic-port instructions,
1237 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1238 performing operations with SFR's causes data to be written more than
1239 once to each SFR. Perhaps SFRs should be handled in special cases...
1240 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1242 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1243 into account for stack starting position,

1245 --extended or -y for Extended Instruction Support,
1246 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1247 (deassignLRs): *** perhaps the most important change, old 'for' code
1248 (commented out for reference), didn't account for some registers which
1249 were left marked 'not free' after a pointer operation. The change
1250 reduces register usage a lot in some cases
1252 2006-03-04 Borut Razem <borut.razem AT siol.net>

3525 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3526 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3527 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3528 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3529 always available in leading double underscore form. The C99 support is
3530 mostly missing, but it's a start.
3531 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3532 reserved identifier "__data".

3610 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3612 * device/lib/printf_large.c: removed inline assembly for portability and
3613 readability. Use printf_fast if speed or size are more important.
3614 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3615 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3617 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3619 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3620 prevent compiler warning
3622 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3624 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3625 moved to level 0 and declared as static. Also they are explicit
3626 placed in access bank. This was necessery because some times they
3627 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3628 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3629 optimizations. Currently only compare to unsigned char is implemented,
3630 * src/pic16/gen.c: added fReturnIdx array,
3631 * (struct resolvedIfx) is moved to gen.h and made public,
3632 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3633 * (aopForSym): added an optimization to directly store in stack of
3634 the operand of a SEND iCode,
3635 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3636 but as registers instead (AOP_REG) using the fReturnIdx array,
3637 * (pic16_freeAsmop): remove the freed register from the
3638 _G.sregsAlloc field,
3639 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3640 a compare of 'WREG',
3641 * (pic16_popGetTempRegCond): changed function prototype, now
3642 function takes also a bitVector argument v which holds the current
3643 set of registers that are allocated for stack access by aopForSym,
3644 registers allocated in aopForSym for accessing stack symbols are not
3645 any more part of the functions usedRegs field,
3646 * (genCall): some times aopOp is called for a stack variable to be
3647 send, aopForSym might perform the push, if this is true make sure
3648 that genCall doesn't push the variable twice by testing _G.resDirect,
3649 * (genFunction): changed testing for unspecified interrupt number
3650 from 256 to INTNO_UNSPEC,
3651 * modified selection scheme of frame pointer generation. Previously
3652 if function did use local registers a frame pointer was generated,
3653 now a frame pointer is generated only if function has arguments
3654 (that need PLUSW2 register access), or has stack arguments, or the
3655 compiler is not instructed to omit the frame pointer,
3656 * (genEndFunction): before restoring local registers that were saved
3657 in the function preamble, also restore the registers that *might*
3658 have been allocated for stack access,
3659 * (genRet): removed some old comments,
3660 * (genCmp, the active (RN's) version): added a call to the
3661 pic16_genCmp_special function to perform the compare with a more
3662 robust and optimized way,
3663 * (genInline): a feature has been added in inline code generation,
3664 which allows a wildcard variable substitution when writing inline
3665 assembly. Code is incomplete and experimental therefore undocumented,
3666 * (genCast): changed order of aopOp for result and right to allow
3667 aopForSym to directly load the result if possible,
3668 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3669 perform an optimized compare on some selected special occasions,
3670 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3671 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3672 generate an IVT any more,
3673 * src/pic16/main.c (pic16_optionsTable): added command line option
3675 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3676 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3678 * src/pic16/NOTES: Raphael Neider added in list of active developers
3679 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3680 jumptable_end to prevent bug #,
3681 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3682 inCond and outCond fields,
3683 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3684 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3685 turn off register spilling,
3686 * (packRegsForOneUse): synced with other ports' versions although it
3687 is not used currently,
3688 * (pic16_packRegisters): added an optimization while reading
3689 structure bitfields, some registers may be saved (malloc code is
3690 decreased by 80 bytes)
3692 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3694 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3695 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3696 this can be optimized more?
3698 2005-03-10 Raphael Neider <rneider AT web.de>
3700 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3701 genNearPointerGet): (hopefully) fixed access to bitfields via
3702 pointers (p->bitN = x; and x = p->bitN; failed)
3704 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3745 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3747 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3748 to keep the correct label reference count when adding/removing references
3749 to labels. A peephole file using this is appended to patch #1144962.

3881 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3882 (sizeof(sectNames) changed to sizeof(sectName))
3883 Both patches fix segfaults under MinGW.
3885 2005-01-23 Raphael Neider <rneider AT web.de>
3887 * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
3888 Safe_[mc]?alloc()'ed variables
3889 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3890 of (byte sized) temporaries (assign them to WREG for now)
3891 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3892 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3893 this might fix SIGSEGVs on MinGW...
3894 * src/SDCCopt.c (killDeadCode): restored original behaviour
3895 (volatile operands might get thrown away though)
3897 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3899 * src/pic16/gen.c: fixed bug #1106975,

3904 * added function attribute 'shadowregs' to take advantage of shadow
3906 * added function attribute 'wparam' as an alternative to the wparam

4336 Adding support for replacing ljmps with sjmps in jumptables
4337 generated for switch statements. For now you need to set the
4338 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4339 Now 4 algorithms for mcs51 jumptable generation are used:
4340 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4341 addresses loaded pc-relative for up to 112 cases and stack-pushing
4342 target addresses loaded with offset from dptr for up to 256 cases.
4344 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4345 * src/mcs51/main.c: adapted constants for switch table generation
4346 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

4360 * src/pic16/device.h,
4361 * src/pic16/genarith.c,
4364 * src/pic16/pcode.c: applied patches #1068154 and #1070213
4366 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4368 Large cummulative patch for pic16 port.
4369 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4370 to call when a stack overflow occurs,
4371 * (malloc.h): added CVS Id tag,
4372 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4374 * added libc directory. The current version of LibC contains string
4375 functions, ctype functions and macros and some functions of the
4376 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4377 be extensively tested in the future. Standard disclaimer here.
4378 Library is not automatically build yet. But one can build it by
4379 invoking 'make' inside the libc directory.
4380 * added ADC library under libio. Preliminary version yet.
4382 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4383 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4384 aopForRemat() now and not by pic16_aopOp(),

4386 temporary registers, its a buggy feature and will be removed,
4387 * (pic16_popGet): set register instance field in AOP_CRY,
4388 * (pic16_outBitC): fixed for results in size greater than 1,
4389 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4390 * (pic16_storeForReturn): optimized return of 0,
4391 * (genCmp): experimental code for new genCmp which uses PIC18's
4392 special compare&skip instructions. Initial tests fail some times
4393 with variables grater than 1 byte in size, so new code is disabled,
4394 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4396 * (genCast): began a fix to optimize the casting of a bit to another
4397 bit, now assigning a bitfield to another bitfield will fail, sorry,
4398 * src/pic16/main.c: disabled the use of lr-support feature,
4399 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4400 * added some function prototypes, added function _debugf prototype,
4401 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4402 bits with offset (case PO_GPR_BIT),
4403 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4405 * (isBankInstruction): modified to return 0 for no banking instruction,
4406 and 1 for banking instruction,
4407 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4408 caused stop processing pCodes after a inline assembly block,
4409 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4410 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4411 registers when it shouldn't,
4412 * src/pic16/ralloc.c (allocReg): add preliminary support for
4413 supporting a limited set of temporary registers,
4415 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4417 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4418 genDataPointerSet): ensure assignments always copy in MSB to LSB
4420 (loadRegFromAop): recognize CLRH optimization,
4421 (genFunction): optimize RECEIVE iCodes in reentrant functions
4423 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4425 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4426 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4428 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4437 instead of sjmp to ret
4438 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4439 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4441 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7423 loaded with the linker search paths (-L arguments) and the libraries
7424 to be linked with the current source (-l arguments). Changes
7425 currently will affect only the pic16 port.
7426 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7427 include path the port specific paths and port specific libraries,

7434 initialization which bypassed the variable initializations block.
7436 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7437 COMPILE_FLAGS and added the --nostdinc option
7439 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7444 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7446 Documenting changes from previous commits.
7447 * configure.in (version 1.56),
7448 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7449 when generating output files to configure the pic16 library,
7450 but now I've commented it out, since gputils aren't installed in the
7451 SF compile farm, so library won't compile
7453 * device/lib/Makefile.in (version 1.56): initially I've added in
7454 target 'all' the prerequestive 'model-pic16' so it compiled the
7455 pic16 library, but now I've commented it out for the same reasons
7457 * added targets 'model-pic16' and 'objects-pic16' to compile the
7459 * added target 'port-specific-objects-pic16' to handle the
7460 generated libraries and copy them into the build/ directory
7461 * added target 'clean-intermediate-pic16' to clean intermediate
7462 files into pic16 directory
7463 * in target 'installdirs' added line to create directory pic16 in
7464 the installation path
7466 * device/include/Makefile.in (version 1.11): in target 'install'
7467 added lines to copy all header files to installation path,
7468 * in target 'installdirs' added line create directory for pic16
7469 headers in the installation path
7471 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7484 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7485 option so that it actually works. Made it specific to the z80, since
7486 the gbz80 doesn't have these kinds of I/O ports.
7488 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7490 * device/include/z180.h,

7503 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7505 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7506 changed interrupt vector table generation to only emit declared vectors.
7507 * device/include/Makefile.in: added missing backslash
7508 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7512 Mainly changes to support compilation of the device libraries
7513 * src/pic16/device.c: stack is allocated via symbol and not
7514 via literal number. The symbol is placed in the corresponding
7515 position of the data ram
7516 * (pic16_dump_section): relocatable and absolute uninitialized
7517 data are now emitted in sorted order to reduce section naming,
7518 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7519 weren't marked as being in the access bank,
7521 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7523 Added portion of GNU PIC Library under the directory
7524 device/include/pic16 and device/lib/pic16. These files
7525 contain the declarations of SFRs for the PIC18Fxx2 devices.
7526 The directory is initialized via configure from toplevel.
7528 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7530 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7531 the spilllocations to be compared correctly
7533 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7535 * src/SDCCast.c (decorateType): fixed bug introduced today
7537 2004-01-12 Borut Razem <borut.razem AT siol.net>

7555 * doc/sdccman.lyx: Moved and added some sections, small changes
7556 all over. Telling LaTeX to be less strict with word spacing
7557 to better keep the right margin. Changed some notes about
7558 maintainance of the ports in section 3.2.1 - is it OK like this?
7560 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7562 SDCC source changes:
7563 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7597 UPPER for immediate operands,
7598 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7600 * src/pic16/peeph.def: all peepholes with movff are commented out,
7601 because there is a problem in the pcode peep optimizer,
7602 * src/pic16/ralloc.c: the register allocator can now reuse local
7603 function symbols for another function. This saves register usage.
7604 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7606 Added file src/pic16/NOTES with information about program writing on
7607 the current port version.

7639 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7642 * src/z80/main.c: added missed needLinkerScript flags (more than
7643 one port structure defined in these file)
7644 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7660 needLinkerScript flag
7662 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7663 * src/pic/glue.c: added variable udata_section_name to
7664 override default uninitialized data segment definition for

7666 * (pic14emitOverlay): modified to emit a commented overlay segment
7667 directive when no overlay data exist
7668 * (picglue): modified to emit uninitialized data segment
7669 according to udata_section_name

7679 2004-01-07 Borut Razem <borut.razem AT siol.net>
7681 * support/scripts/sdcc.nsi: update PATH
7682 * support/scripts/sdcc.ico: craeted

7695 include information about variables allocated to the overlay
7698 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7700 * as/mcs51/lkmain.c: Help about -Y option

7712 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7714 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7715 (default behaviour).
7717 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7719 A python script to validate compiler diagnostic messages. It can be
7720 used to verify that sdcc complains about bad c source code and
7721 gives a good location of the error.
7722 * support/valdiag/Makefile,
7723 * support/valdiag/valdiag.py,
7724 * support/valdiag/tests/*
7726 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7741 Bug reported from Jesus Calvino-Fraga
7743 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7745 * sdcc.spec: updated
7746 * device/include/Makefile.in: don't install CVS directories
7747 * device/lib/Makefile.in: added removal of CVS directories after install
7748 * doc/Makefile: fixed install, added local_icons
7749 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7750 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7751 * src/ds390/gen.c (genRightShift): fixed bug #870788
7752 * src/SDCCast.c (decorateType): fixed bug #870781
7754 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7756 PIC16 port related changes:
7757 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7758 added variable stackPos,
7760 * gen.c: genCall, assignResultValue: added support for
7761 pushing/retrieving function parameters to/from stack,
7762 genFunction,genEndFunction: setup stack frame for the
7764 genAddrOf: will be changed according to bug 863624
7766 * added files genutils.c and genutils.h which contain gen*
7767 debugged and optimised functions extracted from gen.c
7769 * glue.c: added variable 'externs' which holds extern symbols,
7770 pic16emitRegularMap: is modified to properly handle relocatable
7771 symbols under the new scheme,
7772 pic16createInterruptVect: is modified
7773 pic16printPublics: is modified to emit 'global' assembler directives,
7774 added pic16_printExterns to print extern symbols,
7775 pic16glue: initializes stack/frame pointer in the beginning of
7776 the assembly output. Temporary hack, will be corrected later,
7777 because gplink yet does not support stack and SDCC does not
7778 yet support a type of crt0.o object to create the final binary.
7780 * Removed many lines that contain 8051 legacy code.
7781 * The code is finally placed under a 'code' directive.
7782 * Added port specific options.
7784 * _process_pragma: simplified since now we do not need *special*
7785 include file to define SFR registers. But a separate header
7786 will be needed. This will be developed later.
7787 * _pic16_parseOptions: added, parses port specific options:
7788 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7789 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7790 --preplace-udata-with=
7792 * _pic16_setDefaultOptions: modified to initialize section names,
7793 but hack is temporarly out of order since it needs improvement.
7794 * _pic16_genAssemblerPreamble: configuration words are emitted by
7795 their address instead of their name. This part is incomplete and
7796 supports only the 18Fxx2 devices. Other devices will emit an error
7797 during assembly since they do not contain the same set of config
7799 * _pic16_genIVT: is modified,
7801 * pcode.c: added definitions for some hardware registers that are needed
7803 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7804 All PCI entries are updated. Now LFSR is supported.
7805 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7806 * added pic16_newpCodeOpLit2 to support instructions with
7807 two literal arguments
7808 * pic16_pCode2str: corrected code that emits assembler instructions
7809 with two literal operands and those that have an access bit modifier
7810 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7811 this fixes a bug which caused some labels to be lost, when an
7812 assembler directive was added, i.e. banksel,
7813 * pic16_FixRegisterBanking: improved logic that causes the insertion
7815 * InlineFunction: functions that are called once, are not any more
7816 inlined. This can be a port option in the future,
7818 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7820 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7821 hold the corresponding uninitialized symbols,
7822 * pic16_allocProcessorRegister: registers have explicit marked the
7824 * pic16_allocInternalRegister: registers are explicit marked as
7826 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7827 processing list, so bit registers were lost,
7830 * ralloc.h: added field 'accessBank' and original symbol operand
7831 in register definition,
7832 * removed the field isMapped from register definition,
7834 ** Several functions have been removed from various sources:
7835 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7836 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7837 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7838 pic16_assignRelocatableRegisters
7840 ** others have been introduced:
7841 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7842 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7844 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7846 * support/scripts/inc2h.pl: changed definition of BIT_AT
7847 to emit 'sbit at' instead of 'bit at'. This was a request.
7849 PIC16 port related preliminary changes:
7850 * gen.c: prefixed function popRegFromString with
7851 pic16_ and all references to it corrected
7852 * pcode.c: all pic16_pc_* hardware registers prefixed
7853 with underscore (_),
7854 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7855 * ralloc.c: newReg(): when register is REG_SFR then
7856 set address to rIdx,
7857 pic16_allocProcessorRegister(): marks register wasUsed=0
7858 pic16_writeUsedRegs(): added a call to assign processor
7859 registers via pic16_assignFixedRegisters
7861 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7863 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7864 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7865 variables in unused register banks. Also the SSEG is placed
7866 wherever there is enough space for it, and IDATA can be anywhere
7867 in internal RAM. For now compile using -Wl-Y[stack_size].
7868 The mem file is different for this option as well, since it
7869 makes no sense of talking about DSEG lenght.
7871 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7873 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7874 in certain cases, e.g. when ROM assignment, patch provided
7875 from Albert den Haan.
7877 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8920 A few small changes that speed up the peephole optimizer.
8924 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8926 Try to make the peephole optimizer smarter by maintaining
8927 an association between the assembly source code and the
8928 iCodes that originated them. Put this information to use
8929 with a new peephole rule condition "notVolatile" so that
8930 the rules can be aggressive yet still safe.
8935 * src/mcs51/peeph.def
8937 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8941 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8942 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8943 if the left or right operand symbols have the accuse flag set.
8945 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8947 Changed the type of the result of the ! (NOT) operator to char;
8948 previously it returned the same type as the source. This allows
8949 us to eliminate all the genFloatNot functions (all of its target
8950 implementations were very buggy) since !float can use the same
8953 * src/SDCCicode.c (ast2iCode): ! returns char
8954 * src/mcs51/gen.c (genNot, genNotFloat),
8955 * src/ds390/gen.c (genNot, genNotFloat),
8956 * src/z80/gen.c (genNot, genNotFloat),
8957 * src/pic/gen.c (genNot, genNotFloat),
8958 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

8962 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8963 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8964 during interrupts. Ensure WSAVE is located at a shared bank address.
8965 2. Fixed page selection in some places
8966 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8967 the registers name strings.
8968 4. Fixed "signed / unsigned compare" compiler warnings.
8969 5. The PIC port manages its own allocation of the general purpose
8970 registers, but makes no attempt to reuse them. As a result when
8971 compiling it soon runs out of general purpose registers. Some
8972 additional code was added to the files pcode.c and device.c to walk
8973 through the function call tree and rename the registers so that they
8983 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8984 genPlus() & genMinus() when the result is the same as left or right

8990 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8992 Made bitfield a distinct type from bit so that bitfields
8993 convert as per ANSI C and bits retain their traditional
8994 boolean style behaviour. Implemented bitfield support in
9002 * src/ds390/gen.c: bit v bitfield split
9003 * src/z80/gen.c: New support for bitfields
9004 * support/regression/tests/bitfields.c: reenabled z80,
9007 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9009 Rules 246.x, 247.x relate to bitfields, the others speed up
9010 access to xdata mapped I/O devices.
9012 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9014 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9016 Cleaned up genPackBits and genUnpackBits and added two helper
9017 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9018 for literal assignments in genPackBits (thanks to Frieder for
9024 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9026 Fixed bug #748310 (pointer to function type mishandled when the
9027 function name is omitted). Also fixed a SIGSEGV when a function
9028 attribute (reentrant, etc) is used on a non-function or on a
9029 function but misplaced before the parameter list.
9031 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9033 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9056 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9058 Made the constant following the "interrupt" keyword optional. If
9059 omitted, the function will not automatically be given an entry
9060 in the interrupt vector table (similar to #pragma NOIV, but
9061 less syntacticly kludgy). The interrupt number is also now
9062 range checked. Also fixed a bug in the high order bit example

9076 * src/SDCCicode.c (operandOperation): rewritten some ops
9077 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9078 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9080 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9081 be re-activated by defining REDUCE_LITERALS)
9082 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9083 unsigned, but are signed by default
9084 * src/SDCCval.c (constVal): rearranged
9085 * src/SDCCval.c (valMod): preliminary fix
9086 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9531 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9532 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9533 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9536 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9538 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9539 the regression tests I'm not brave enough to enable 245.b, 245.c
9540 * doc/sdccman.lyx: added latex preamble for hyperref package.
9541 Using pdflatex this will give you a hyperlinked pdf file with
9542 bookmarks. (prepend '%' before /usepackage if this breaks something)

9554 * src/SDCCglue.c (printIval): fixed bug #739934
9556 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
9558 Applied patch from bug 737905 (renamed yylineo to mylineno):
9565 * src/pic16/pcode.c: Cleaned warnings
9566 * src/pic16/pcodeflow.c: Cleaned warnings
9567 * src/pic16/pcoderegs.c: Cleaned warnings

9580 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9582 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9583 it can be defined with CFLAGS when running configure
9584 * src/SDCCmain.c: fixed compiling + linking with object files
9586 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9588 * configure.in: configure for pic16 port,
9589 added --disable-pic16-port
9590 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9591 * src/SDCCmain.c: linkOptions is changed to set *,
9592 added if/endif conditional macros to remove options help
9593 messages from optionsTable when a port is not configured, added
9594 support for the PIc16 port in the ports table, when executing
9595 the compiler with no port specified on command line, a default
9596 port is selected with the new macro DEFAULT_PORT which is
9597 defined in port.h, in setDefaultOptions() linkOptions is removed
9598 from initialization assignment, since now it is a set,
9599 parseCmdLine uses setParseWithComma for linkOptions, in
9600 linkEdit() linkOptions are accessed with new function indexSet()
9601 which returns the i'th item of a set variable. See SDCCset.c, in
9602 linkEdit() when calling buildCmdLine(), added linkOptions as
9603 last argument. Now users can pass arguments to gplink via the
9604 -Wl option, main() uses pic16glue() to glue up pic16 programs
9605 * src/SDCCpeeph.c: various changes to support pic16
9606 * src/SDCCset.c: added function void *indexSet(set *, int) to

9616 * src/pic16/glue.c: commented out some error producing lines
9617 * src/pic16/main.c: __config directives are commented out to stop
9618 gpasm complaining and test the linkage with gplink, _linkCmd and
9619 _asmCmd changed to be more gplink and gpasm friendly
9620 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9621 produced an error when parsed, peep rule 12 is added to utilize
9622 movff, but it is commented out since the pCode does not support
9623 yet a command with 2 address arguments
9625 2003-05-18 <johan AT balder>
9627 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9628 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9629 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9652 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9654 2003-05-11 Borut Razem <borut.razem AT siol.net>
9656 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9657 the path of bin directory, so that PATH is the only env. variable, which has to be set
9658 in case of standard installation.
9659 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10688 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10690 * in \sdcc\as\mcs51\ changed these files in order to create an
10691 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10692 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10693 following files to include the previous two files: aslink.dsp,
10694 Makefile.aslink, Makefile.bcc, and Makefile.in.
10696 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10697 .adb instead of .cdb
10699 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10701 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10702 value from option --iram-size.
10704 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10706 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10709 2002-09-18 <wiml AT hhhh.org>
10711 * SDCClrange.h: exposed setFromRange() and setToRange()
10712 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10713 packRegsForAccUse() (bug 542397)
10714 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10715 multiple times and emitting the fetch operations more than once
10716 added aopGetUsesAcc() function to allow binary operators to
10717 fetch their operands in the correct order; made genMinus() emit
10718 compact code for X = LITERAL - Y
10720 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10721 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10722 sprintf() in line 1267.
10724 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10725 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10728 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10729 Changes to aslink (All the changes are marked with 'JCF'):
10731 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10734 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10735 area BSEG. Also moves, if possible, the DATA area down into the internal
10736 ram so more space is available.
10738 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10741 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10742 not bytes. Function summary() which creates a memory usage summary
10743 file with extension .mem. Reports of overlaping stack and small stack
10744 size. If the space for the stack is less than 16 bytes aslink trows a
10747 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10748 the 8051. Option 'y' for memory summary output file.
10750 Changes to sdcc (All the changes are marked with 'JCF'):
10752 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10754 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10755 overlaying area for it (uses RegBankUsed[4]).
10757 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10758 bank zero as used by default. By default aslink locates the stack
10759 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10760 the creation of the .mem file. Delegates the allocation of data area
10761 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10762 the begining of the stack area to aslink.
10764 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10765 glue() in SDCCglue.c creates an area for it.
10767 2002-09-03 Borut Razem <borut.razem AT siol.net>
10768 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10769 sdcc/src/pic/glue.c:
10770 introduced atexit() handler for teporay files removal in case of
10771 errors, assertions, ...
10773 2002-08-29 Borut Razem <borut.razem AT siol.net>
10774 * sdcc/support/cpp2/auto-host_vc_in.h:
10775 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10776 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10777 Maybe there is a similar problem with BORLANDC? It should be checked!
10779 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10780 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10781 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10782 was not executed, and the compiler (cl) launched a warning:
10783 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10785 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10786 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10788 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10796 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10797 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10798 - added Release configuration in VS projects
10799 - review of compiler an linker options
10800 - VC .exe files are generated in bin_vc directory, not to interfere
10801 with binaries generated from other projects (cygwin, mingw, bcc ...)
10803 * sdcc/src/yacc.dsp: added
10805 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10806 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10807 and insert the version number definitions from .version
10809 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10811 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10818 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10820 2002-08-11 Borut Razem <borut.razem AT siol.net>
10821 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10823 2002-08-10 Borut Razem <borut.razem AT siol.net>
10824 * src/SDCCmain.c (main):
10825 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10826 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10827 The consequence was that some temporary files were not removed.
10830 unification of code in functions tempfilename() and tempfile():
10831 function tempnam() is defined in Visual Studio 6.0 and .NET
10833 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10835 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10836 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10837 - removed compiler command line option /WX: Treats all warnings as errors
10838 - update a list of source files, included into the project
10840 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10841 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10842 changed project type to Generic Project so that can be correcly converted to VS.NET project
10844 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10846 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10850 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10851 added return 0 statements after assert() to make compiler happy
10853 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10854 added newline in the def file to keep MSC compiler satisfied
10856 * sdcc/src/z80/gen.c:
10857 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10858 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10859 - solved MSC error in function aopDump()
10861 * sdcc_vc.h: define PREFIX as "\\sdcc"
10863 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11036 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11038 * sdcc/src/SDCCloop.c:
11039 Previous fix was not good. basic blocks that have "break" or "return" are
11040 not really partof a loop , but live ranges used in these blocks should
