967 genRightShift): fixed bug with non-constant bit shift stored to
968 a volatile result (SF Open Discussion forum thread #1616749).
969 Single byte case is not yet optimized.

2872 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2874 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2875 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2877 One basic decision: e.g. src/clean.mk includes further files. In order
2878 to make this work there are two solutions:
2879 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2880 run configure on them. This way they can use
2881 'include $(srcdir)/port-clean.mk'
2882 - always include clean.mk by the Makefile at the same level. To avoid
2883 that `make clean` tries to include and build Makefile.dep the
2884 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2885 implemented, because now even `make uninstall` doesn't create
2886 Makefile.in. clean.mk could be eliminated by pasting it in
2889 * debugger/mcs51/Makefile.in: build own objects from library sources
2890 (SLIB, SDCC) in current directory
2892 * configure, configure.in: renamed --disable-device-lib-build in
2893 --disable-device-lib; added --enable-doc, the required tools are
2894 searched by configure; added result message; the toolchain for the
2895 belonging ports are now only built, if the port is enabled.
2897 * support/regression/*: all output is written in directory gen, because
2898 the fwk and ports directories don't livet in the build tree using vpath
2900 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2901 --disable-device-lib, added --enable-doc, added section VPATH
2903 * sim/ucsim/configure.in,
2904 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2905 z80 are enabled by default
2907 2006-04-24 Raphael Neider <rneider AT web.de>
2909 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2910 to config word, "pic14_"-prefixed some extern functions
2911 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2912 config word has been found
2913 * src/pic/device.h: added prototypes
2914 * src/pic/pcode.c: added "pic14_"-prefix where needed
2915 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2917 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2919 (pic14emitRegularMap): ignore config words,
2920 (pic14createInterruptVect): moved generating __config directives away
2921 (picglue): have __config directives emitted
2923 2006-04-24 Borut Razem <borut.razem AT siol.net>

2930 registers that have not been assigned proper liveranges,
2931 fixes #1469504 and #1474602,
2932 (pCodeRegOptimizeRegUsage): fixed typo in comment

3178 implemented patch 1120823 Thanks to Willy De la Court (normal
3179 interrupts need an interrupt number now if they are made critical),
3180 and enabled nesting of critical functions though not for gbz80
3181 (genCritical, genEndCritical): added functions
3182 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3183 * src/z80/mappings.i: added "ei" to all mappings

3192 2006-03-16 Raphael Neider <rneider AT web.de>
3194 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3195 the left operand is shorter than the result (c* = lit-c* + int),
3197 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3200 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3202 * src/.version: increased version number to 2.5.5
3203 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3204 linking is done manually in pic16 port's _linkEdit,
3205 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3206 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3207 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3208 allocate asmop as AOP_ACC,
3209 (aopForRemat): added parameter 'bool result' in function declaration,
3210 (pic16_aopGet): return AOP_ACC when accessing WREG,
3211 (pic16_popGetTempReg): minor modification,
3212 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3213 'pic16_allocWithIdx',

3215 calling function in absolute addresses,
3216 (genAssign): take into account AOP_ACC asmop,

3220 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3222 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3223 call to allocReg, not by manually allocating a new one,
3224 (pic16_assignRegisters): now before going through the register
3225 allocating functions mark all registers as free. This eliminates some
3226 side effects resulting from peephole parser done earlier in the backbone
3228 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3230 * src/SDCCicode.c (geniCodeLogic),

3250 (aopForSym, aopOp): increment asmop.allocated if reused,
3251 (freeAsmop): decrement asmop.allocated and check for zero instead of
3253 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3254 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3255 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3278 2006-03-06 Borut Razem <borut.razem AT siol.net>
3280 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3281 made the linker quiet
3283 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

3286 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3287 which dumps before the function entry point a data byte which represents
3288 the number of the local variables used by the specified function, added
3289 'xinst' for initial support for Extended Instruction Support,
3290 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3291 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3292 port->fun_prefix anymore (may change later),
3293 (genFunction, genEndFunction): do not store/restore local registers for
3294 _main (this should take care the --main-return command line option in
3296 (genOr): removed some legacy pic-port instructions,
3297 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3298 performing operations with SFR's causes data to be written more than
3299 once to each SFR. Perhaps SFRs should be handled in special cases...
3300 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3302 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3303 into account for stack starting position,
3304 (struct OPTIONS pic16_optionsTable): added command line argument
3305 --extended or -y for Extended Instruction Support,
3306 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3307 (deassignLRs): *** perhaps the most important change, old 'for' code
3308 (commented out for reference), didn't account for some registers which
3309 were left marked 'not free' after a pointer operation. The change
3310 reduces register usage a lot in some cases
3312 2006-03-04 Borut Razem <borut.razem AT siol.net>
3314 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5577 on rIfx (genCmp was broken)
5579 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5581 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
5582 * src/z80/main.c (_keywords[]),
5583 * src/SDCCglobal.h (struct options),
5585 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5586 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5587 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5588 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5589 always available in leading double underscore form. The C99 support is
5590 mostly missing, but it's a start.
5591 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5592 reserved identifier "__data".
5594 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
5596 * src/mcs51/peeph.def: fixed bug 1170013

5607 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5609 * src/port.h (struct PORT),

5638 immedDom() returning wrong block; probably fixes bug #1160833)
5640 2005-03-20 Borut Razem <borut.razem AT siol.net>
5642 * support/scripts/inc2h.pl: WIN32 port

5646 * device/lib/makefile.in: added abs.c and labs.c
5648 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5650 * device/include/stdint.h: added
5651 * device/lib/abs.c: added

5670 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5672 * device/lib/printf_large.c: removed inline assembly for portability and
5673 readability. Use printf_fast if speed or size are more important.
5674 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5675 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5677 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5679 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5680 prevent compiler warning
5682 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5684 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5685 moved to level 0 and declared as static. Also they are explicit
5686 placed in access bank. This was necessery because some times they
5687 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5688 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5689 optimizations. Currently only compare to unsigned char is implemented,
5690 * src/pic16/gen.c: added fReturnIdx array,
5691 * (struct resolvedIfx) is moved to gen.h and made public,
5692 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5693 * (aopForSym): added an optimization to directly store in stack of
5694 the operand of a SEND iCode,
5695 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5696 but as registers instead (AOP_REG) using the fReturnIdx array,
5697 * (pic16_freeAsmop): remove the freed register from the
5698 _G.sregsAlloc field,
5699 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5700 a compare of 'WREG',
5701 * (pic16_popGetTempRegCond): changed function prototype, now
5702 function takes also a bitVector argument v which holds the current
5703 set of registers that are allocated for stack access by aopForSym,
5704 registers allocated in aopForSym for accessing stack symbols are not
5705 any more part of the functions usedRegs field,
5706 * (genCall): some times aopOp is called for a stack variable to be
5707 send, aopForSym might perform the push, if this is true make sure
5708 that genCall doesn't push the variable twice by testing _G.resDirect,
5709 * (genFunction): changed testing for unspecified interrupt number
5710 from 256 to INTNO_UNSPEC,
5711 * modified selection scheme of frame pointer generation. Previously
5712 if function did use local registers a frame pointer was generated,
5713 now a frame pointer is generated only if function has arguments
5714 (that need PLUSW2 register access), or has stack arguments, or the
5715 compiler is not instructed to omit the frame pointer,
5716 * (genEndFunction): before restoring local registers that were saved
5717 in the function preamble, also restore the registers that *might*
5718 have been allocated for stack access,
5719 * (genRet): removed some old comments,
5720 * (genCmp, the active (RN's) version): added a call to the
5721 pic16_genCmp_special function to perform the compare with a more
5722 robust and optimized way,
5723 * (genInline): a feature has been added in inline code generation,
5724 which allows a wildcard variable substitution when writing inline
5725 assembly. Code is incomplete and experimental therefore undocumented,
5726 * (genCast): changed order of aopOp for result and right to allow
5727 aopForSym to directly load the result if possible,
5728 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5729 perform an optimized compare on some selected special occasions,
5730 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5731 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5732 generate an IVT any more,
5733 * src/pic16/main.c (pic16_optionsTable): added command line option
5735 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5736 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5738 * src/pic16/NOTES: Raphael Neider added in list of active developers
5739 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5740 jumptable_end to prevent bug #,
5741 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5742 inCond and outCond fields,
5743 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5744 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5745 turn off register spilling,
5746 * (packRegsForOneUse): synced with other ports' versions although it
5747 is not used currently,
5748 * (pic16_packRegisters): added an optimization while reading
5749 structure bitfields, some registers may be saved (malloc code is
5750 decreased by 80 bytes)
5752 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5754 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5755 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5756 this can be optimized more?
5758 2005-03-10 Raphael Neider <rneider AT web.de>
5760 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5761 genNearPointerGet): (hopefully) fixed access to bitfields via
5762 pointers (p->bitN = x; and x = p->bitN; failed)
5764 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5950 of (byte sized) temporaries (assign them to WREG for now)
5951 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5952 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5953 this might fix SIGSEGVs on MinGW...
5954 * src/SDCCopt.c (killDeadCode): restored original behaviour
5955 (volatile operands might get thrown away though)
5957 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5959 * src/pic16/gen.c: fixed bug #1106975,

6429 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6430 to call when a stack overflow occurs,
6431 * (malloc.h): added CVS Id tag,
6432 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6434 * added libc directory. The current version of LibC contains string
6435 functions, ctype functions and macros and some functions of the
6436 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6437 be extensively tested in the future. Standard disclaimer here.
6438 Library is not automatically build yet. But one can build it by
6439 invoking 'make' inside the libc directory.
6440 * added ADC library under libio. Preliminary version yet.
6442 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6443 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6444 aopForRemat() now and not by pic16_aopOp(),
6445 * (pic16_popGetTempReg): removed warning messgae when allocating
6446 temporary registers, its a buggy feature and will be removed,
6447 * (pic16_popGet): set register instance field in AOP_CRY,
6448 * (pic16_outBitC): fixed for results in size greater than 1,
6449 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6450 * (pic16_storeForReturn): optimized return of 0,
6451 * (genCmp): experimental code for new genCmp which uses PIC18's
6452 special compare&skip instructions. Initial tests fail some times
6453 with variables grater than 1 byte in size, so new code is disabled,
6454 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6456 * (genCast): began a fix to optimize the casting of a bit to another
6457 bit, now assigning a bitfield to another bitfield will fail, sorry,
6458 * src/pic16/main.c: disabled the use of lr-support feature,
6459 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6460 * added some function prototypes, added function _debugf prototype,
6461 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6462 bits with offset (case PO_GPR_BIT),
6463 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6465 * (isBankInstruction): modified to return 0 for no banking instruction,
6466 and 1 for banking instruction,
6467 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6468 caused stop processing pCodes after a inline assembly block,
6469 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6470 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6471 registers when it shouldn't,
6472 * src/pic16/ralloc.c (allocReg): add preliminary support for
6473 supporting a limited set of temporary registers,
6475 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6477 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6478 genDataPointerSet): ensure assignments always copy in MSB to LSB
6480 (loadRegFromAop): recognize CLRH optimization,
6481 (genFunction): optimize RECEIVE iCodes in reentrant functions
6483 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6485 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6486 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
6488 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
6489 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
6490 contiguous with data
6492 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6494 * device/lib/_gptrget.c (_gptrget),
6495 * device/lib/_gptrgetc.c (_gptrgetc),
6496 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6497 instead of sjmp to ret
6498 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6499 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6501 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9480 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9482 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9483 loaded with the linker search paths (-L arguments) and the libraries
9484 to be linked with the current source (-l arguments). Changes
9485 currently will affect only the pic16 port.
9486 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9487 include path the port specific paths and port specific libraries,
9488 * gplink command now contains the $3 argument,
9489 * src/pic16/device.h,
9490 * src/pic16/device.c,: structure PIC_device is made public and
9491 renamed to PIC16_device, the same for variable Pics which is renamed

9506 Documenting changes from previous commits.
9507 * configure.in (version 1.56),
9508 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9509 when generating output files to configure the pic16 library,
9510 but now I've commented it out, since gputils aren't installed in the
9511 SF compile farm, so library won't compile
9513 * device/lib/Makefile.in (version 1.56): initially I've added in
9514 target 'all' the prerequestive 'model-pic16' so it compiled the
9515 pic16 library, but now I've commented it out for the same reasons
9517 * added targets 'model-pic16' and 'objects-pic16' to compile the
9519 * added target 'port-specific-objects-pic16' to handle the
9520 generated libraries and copy them into the build/ directory
9521 * added target 'clean-intermediate-pic16' to clean intermediate
9522 files into pic16 directory
9523 * in target 'installdirs' added line to create directory pic16 in
9524 the installation path

9574 via literal number. The symbol is placed in the corresponding
9575 position of the data ram
9576 * (pic16_dump_section): relocatable and absolute uninitialized
9577 data are now emitted in sorted order to reduce section naming,
9578 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9579 weren't marked as being in the access bank,
9581 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9583 Added portion of GNU PIC Library under the directory
9584 device/include/pic16 and device/lib/pic16. These files
9585 contain the declarations of SFRs for the PIC18Fxx2 devices.
9586 The directory is initialized via configure from toplevel.
9588 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9590 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

9616 all over. Telling LaTeX to be less strict with word spacing
9617 to better keep the right margin. Changed some notes about
9618 maintainance of the ports in section 3.2.1 - is it OK like this?
9620 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9658 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9660 * src/pic16/peeph.def: all peepholes with movff are commented out,
9661 because there is a problem in the pcode peep optimizer,
9662 * src/pic16/ralloc.c: the register allocator can now reuse local

9699 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9702 * src/z80/main.c: added missed needLinkerScript flags (more than
9703 one port structure defined in these file)
9704 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9720 needLinkerScript flag
9722 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9723 * src/pic/glue.c: added variable udata_section_name to
9724 override default uninitialized data segment definition for
9725 devices only with SHAREBANK memory (reported from Erik Epetrich)
9726 * (pic14emitOverlay): modified to emit a commented overlay segment
9727 directive when no overlay data exist
9728 * (picglue): modified to emit uninitialized data segment
9729 according to udata_section_name

9739 2004-01-07 Borut Razem <borut.razem AT siol.net>
9741 * support/scripts/sdcc.nsi: update PATH
9742 * support/scripts/sdcc.ico: craeted

9755 include information about variables allocated to the overlay
9758 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9760 * as/mcs51/lkmain.c: Help about -Y option

9770 LEFT_OP (left shift)
9772 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9774 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9775 (default behaviour).
9777 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9779 A python script to validate compiler diagnostic messages. It can be
9780 used to verify that sdcc complains about bad c source code and
9781 gives a good location of the error.
9782 * support/valdiag/Makefile,
9783 * support/valdiag/valdiag.py,
9784 * support/valdiag/tests/*
9786 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9788 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9799 * src/common.h: added ifndef/define/endif macros
9800 around the header file.
9801 Bug reported from Jesus Calvino-Fraga
9803 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9805 * sdcc.spec: updated
9806 * device/include/Makefile.in: don't install CVS directories
9807 * device/lib/Makefile.in: added removal of CVS directories after install
9808 * doc/Makefile: fixed install, added local_icons
9809 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9810 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9811 * src/ds390/gen.c (genRightShift): fixed bug #870788
9812 * src/SDCCast.c (decorateType): fixed bug #870781
9814 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9816 PIC16 port related changes:
9817 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9818 added variable stackPos,
9820 * gen.c: genCall, assignResultValue: added support for
9821 pushing/retrieving function parameters to/from stack,
9822 genFunction,genEndFunction: setup stack frame for the
9824 genAddrOf: will be changed according to bug 863624
9826 * added files genutils.c and genutils.h which contain gen*
9827 debugged and optimised functions extracted from gen.c
9829 * glue.c: added variable 'externs' which holds extern symbols,
9830 pic16emitRegularMap: is modified to properly handle relocatable
9831 symbols under the new scheme,
9832 pic16createInterruptVect: is modified
9833 pic16printPublics: is modified to emit 'global' assembler directives,
9834 added pic16_printExterns to print extern symbols,
9835 pic16glue: initializes stack/frame pointer in the beginning of
9836 the assembly output. Temporary hack, will be corrected later,
9837 because gplink yet does not support stack and SDCC does not
9838 yet support a type of crt0.o object to create the final binary.
9840 * Removed many lines that contain 8051 legacy code.
9841 * The code is finally placed under a 'code' directive.
9842 * Added port specific options.
9844 * _process_pragma: simplified since now we do not need *special*
9845 include file to define SFR registers. But a separate header
9846 will be needed. This will be developed later.
9847 * _pic16_parseOptions: added, parses port specific options:
9848 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9849 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9850 --preplace-udata-with=
9852 * _pic16_setDefaultOptions: modified to initialize section names,
9853 but hack is temporarly out of order since it needs improvement.
9854 * _pic16_genAssemblerPreamble: configuration words are emitted by
9855 their address instead of their name. This part is incomplete and
9856 supports only the 18Fxx2 devices. Other devices will emit an error
9857 during assembly since they do not contain the same set of config
9859 * _pic16_genIVT: is modified,
9861 * pcode.c: added definitions for some hardware registers that are needed
9863 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9864 All PCI entries are updated. Now LFSR is supported.
9865 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9866 * added pic16_newpCodeOpLit2 to support instructions with
9867 two literal arguments
9868 * pic16_pCode2str: corrected code that emits assembler instructions
9869 with two literal operands and those that have an access bit modifier
9870 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9871 this fixes a bug which caused some labels to be lost, when an
9872 assembler directive was added, i.e. banksel,
9873 * pic16_FixRegisterBanking: improved logic that causes the insertion
9875 * InlineFunction: functions that are called once, are not any more
9876 inlined. This can be a port option in the future,
9878 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9880 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9881 hold the corresponding uninitialized symbols,
9882 * pic16_allocProcessorRegister: registers have explicit marked the
9884 * pic16_allocInternalRegister: registers are explicit marked as
9886 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9887 processing list, so bit registers were lost,
9890 * ralloc.h: added field 'accessBank' and original symbol operand
9891 in register definition,
9892 * removed the field isMapped from register definition,
9894 ** Several functions have been removed from various sources:
9895 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9896 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9897 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9898 pic16_assignRelocatableRegisters
9900 ** others have been introduced:
9901 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9902 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9904 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9906 * support/scripts/inc2h.pl: changed definition of BIT_AT
9907 to emit 'sbit at' instead of 'bit at'. This was a request.
9909 PIC16 port related preliminary changes:
9910 * gen.c: prefixed function popRegFromString with
9911 pic16_ and all references to it corrected
9912 * pcode.c: all pic16_pc_* hardware registers prefixed
9913 with underscore (_),
9914 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9915 * ralloc.c: newReg(): when register is REG_SFR then
9916 set address to rIdx,
9917 pic16_allocProcessorRegister(): marks register wasUsed=0
9918 pic16_writeUsedRegs(): added a call to assign processor
9919 registers via pic16_assignFixedRegisters
9921 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9923 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9924 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9925 variables in unused register banks. Also the SSEG is placed
9926 wherever there is enough space for it, and IDATA can be anywhere
9927 in internal RAM. For now compile using -Wl-Y[stack_size].
9928 The mem file is different for this option as well, since it
9929 makes no sense of talking about DSEG lenght.
9931 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9933 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9934 in certain cases, e.g. when ROM assignment, patch provided
9935 from Albert den Haan.
9937 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10180 it breaks with bitfields, extern declarations, and gcse analysis.
10181 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10182 could be assigned through a pointer, so don't complain.

10490 not occur if the control variable is involved with a
10491 relational operator.

10961 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10962 type for bits was changed. It resulted in bit variables becoming
10963 global, which is not permitted in PIC 14 assembly output.
10965 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10967 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10969 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10971 Z80 and MCS51 linkers complaint if a public symbol is defined
10972 in more than one library module:
10976 * as/mcs51/Makefile.in
10978 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10980 A few small changes that speed up the peephole optimizer.
10984 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10986 Try to make the peephole optimizer smarter by maintaining
10987 an association between the assembly source code and the
10988 iCodes that originated them. Put this information to use
10989 with a new peephole rule condition "notVolatile" so that
10990 the rules can be aggressive yet still safe.
10995 * src/mcs51/peeph.def
10997 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11001 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11002 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11003 if the left or right operand symbols have the accuse flag set.
11005 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11007 Changed the type of the result of the ! (NOT) operator to char;
11008 previously it returned the same type as the source. This allows
11009 us to eliminate all the genFloatNot functions (all of its target
11010 implementations were very buggy) since !float can use the same
11013 * src/SDCCicode.c (ast2iCode): ! returns char
11014 * src/mcs51/gen.c (genNot, genNotFloat),
11015 * src/ds390/gen.c (genNot, genNotFloat),
11016 * src/z80/gen.c (genNot, genNotFloat),
11017 * src/pic/gen.c (genNot, genNotFloat),
11018 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11022 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11023 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11024 during interrupts. Ensure WSAVE is located at a shared bank address.
11025 2. Fixed page selection in some places
11026 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11027 the registers name strings.
11028 4. Fixed "signed / unsigned compare" compiler warnings.
11029 5. The PIC port manages its own allocation of the general purpose
11030 registers, but makes no attempt to reuse them. As a result when
11031 compiling it soon runs out of general purpose registers. Some
11032 additional code was added to the files pcode.c and device.c to walk
11033 through the function call tree and rename the registers so that they
11043 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11044 genPlus() & genMinus() when the result is the same as left or right
11046 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11048 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11050 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11052 Made bitfield a distinct type from bit so that bitfields
11053 convert as per ANSI C and bits retain their traditional
11054 boolean style behaviour. Implemented bitfield support in
11062 * src/ds390/gen.c: bit v bitfield split
11063 * src/z80/gen.c: New support for bitfields
11064 * support/regression/tests/bitfields.c: reenabled z80,
11067 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11069 Rules 246.x, 247.x relate to bitfields, the others speed up
11070 access to xdata mapped I/O devices.
11072 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11074 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11076 Cleaned up genPackBits and genUnpackBits and added two helper
11077 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11078 for literal assignments in genPackBits (thanks to Frieder for
11084 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11086 Fixed bug #748310 (pointer to function type mishandled when the
11087 function name is omitted). Also fixed a SIGSEGV when a function
11088 attribute (reentrant, etc) is used on a non-function or on a
11089 function but misplaced before the parameter list.
11091 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11093 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11094 * support/Util/SDCCerr.h,
11095 * support/Util/SDCCerr.c: Added func attr misuse error msg
11097 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11099 Fixed bug #787649 by anonymous
11100 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11101 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11103 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11105 Fixed numerous bitfield problems.
11107 * src/SDCC.y: More bitfield related error checking
11109 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
11110 * support/Util/SDCCerr.h,
11111 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
11112 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs

11114 * support/regression/tests/bitfields.c: tests added
11116 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11118 Made the constant following the "interrupt" keyword optional. If
11119 omitted, the function will not automatically be given an entry
11120 in the interrupt vector table (similar to #pragma NOIV, but
11121 less syntacticly kludgy). The interrupt number is also now
11122 range checked. Also fixed a bug in the high order bit example
11129 * support/Util/SDCCerr.c
11130 * support/Util/SDCCerr.h
11133 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11136 * src/SDCCicode.c (operandOperation): rewritten some ops
11137 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11138 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11140 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11141 be re-activated by defining REDUCE_LITERALS)
11142 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11143 unsigned, but are signed by default
11144 * src/SDCCval.c (constVal): rearranged
11145 * src/SDCCval.c (valMod): preliminary fix
11146 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11186 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11187 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11188 constants are unsigned; added recognition of "u" flag for unsigned
11189 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11190 * src/SDCCval.c (valDiv, valMod): fixed signdness

11598 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11599 the regression tests I'm not brave enough to enable 245.b, 245.c
11600 * doc/sdccman.lyx: added latex preamble for hyperref package.
11601 Using pdflatex this will give you a hyperlinked pdf file with
11602 bookmarks. (prepend '%' before /usepackage if this breaks something)

11652 added if/endif conditional macros to remove options help
11653 messages from optionsTable when a port is not configured, added
11654 support for the PIc16 port in the ports table, when executing
11655 the compiler with no port specified on command line, a default
11656 port is selected with the new macro DEFAULT_PORT which is
11657 defined in port.h, in setDefaultOptions() linkOptions is removed
11658 from initialization assignment, since now it is a set,
11659 parseCmdLine uses setParseWithComma for linkOptions, in
11660 linkEdit() linkOptions are accessed with new function indexSet()
11661 which returns the i'th item of a set variable. See SDCCset.c, in
11662 linkEdit() when calling buildCmdLine(), added linkOptions as
11663 last argument. Now users can pass arguments to gplink via the
11664 -Wl option, main() uses pic16glue() to glue up pic16 programs

11676 * src/pic16/glue.c: commented out some error producing lines
11677 * src/pic16/main.c: __config directives are commented out to stop
11678 gpasm complaining and test the linkage with gplink, _linkCmd and
11679 _asmCmd changed to be more gplink and gpasm friendly
11680 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11681 produced an error when parsed, peep rule 12 is added to utilize
11682 movff, but it is commented out since the pCode does not support
11683 yet a command with 2 address arguments
11685 2003-05-18 <johan AT balder>
11687 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12794 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12795 area BSEG. Also moves, if possible, the DATA area down into the internal
12796 ram so more space is available.
12798 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12801 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12802 not bytes. Function summary() which creates a memory usage summary
12803 file with extension .mem. Reports of overlaping stack and small stack
12804 size. If the space for the stack is less than 16 bytes aslink trows a
12807 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12808 the 8051. Option 'y' for memory summary output file.
12810 Changes to sdcc (All the changes are marked with 'JCF'):
12812 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12814 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12815 overlaying area for it (uses RegBankUsed[4]).
12817 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12818 bank zero as used by default. By default aslink locates the stack
12819 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12820 the creation of the .mem file. Delegates the allocation of data area
12821 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12822 the begining of the stack area to aslink.
12824 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12825 glue() in SDCCglue.c creates an area for it.
12827 2002-09-03 Borut Razem <borut.razem AT siol.net>
12828 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12829 sdcc/src/pic/glue.c:
12830 introduced atexit() handler for teporay files removal in case of
12831 errors, assertions, ...
12833 2002-08-29 Borut Razem <borut.razem AT siol.net>
12834 * sdcc/support/cpp2/auto-host_vc_in.h:
12835 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12836 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12837 Maybe there is a similar problem with BORLANDC? It should be checked!
12839 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12840 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12841 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12842 was not executed, and the compiler (cl) launched a warning:
12843 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12845 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12846 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

12851 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12852 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12853 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12854 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12855 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12856 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12857 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12858 - added Release configuration in VS projects
12859 - review of compiler an linker options
12860 - VC .exe files are generated in bin_vc directory, not to interfere
12861 with binaries generated from other projects (cygwin, mingw, bcc ...)
12863 * sdcc/src/yacc.dsp: added
12865 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12866 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12867 and insert the version number definitions from .version
12869 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12871 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12872 added - genarate auto-host.h using auto-host_vc_in.h as template
12875 removed from CVS, generated automatically
12877 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12878 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12880 2002-08-11 Borut Razem <borut.razem AT siol.net>
12881 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12883 2002-08-10 Borut Razem <borut.razem AT siol.net>
12884 * src/SDCCmain.c (main):
12885 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12886 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12887 The consequence was that some temporary files were not removed.
12890 unification of code in functions tempfilename() and tempfile():
12891 function tempnam() is defined in Visual Studio 6.0 and .NET
12893 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12895 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12896 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12897 - removed compiler command line option /WX: Treats all warnings as errors
12898 - update a list of source files, included into the project
12900 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12901 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12902 changed project type to Generic Project so that can be correcly converted to VS.NET project
12904 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12906 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12908 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12910 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12911 added return 0 statements after assert() to make compiler happy
12913 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12914 added newline in the def file to keep MSC compiler satisfied
12916 * sdcc/src/z80/gen.c:
12917 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12918 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12919 - solved MSC error in function aopDump()
12921 * sdcc_vc.h: define PREFIX as "\\sdcc"
12923 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12975 Initialized the new field char *Processor field to NULL in all ports
12978 Compiler generated registers for interrupt context saving
12979 were not getting allocated.
12981 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

13096 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13098 * sdcc/src/SDCCloop.c:
13099 Previous fix was not good. basic blocks that have "break" or "return" are
13100 not really partof a loop , but live ranges used in these blocks should
13101 be live thru the entire loop, so set partOfLoop but don't add them to
13104 2002-02-21 <johan AT FRIJA>
13106 * src/SDCCcse.c: fixed bug #514308
13108 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
