922 on rIfx (genCmp was broken)
924 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
926 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
927 * src/z80/main.c (_keywords[]),
928 * src/SDCCglobal.h (struct options),
930 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
931 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
932 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
933 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
934 always available in leading double underscore form. The C99 support is
935 mostly missing, but it's a start.
936 * support/regression/tests/bug-227710.c: fixed nonconforming use of
937 reserved identifier "__data".
939 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1015 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1017 * device/lib/printf_large.c: removed inline assembly for portability and
1018 readability. Use printf_fast if speed or size are more important.
1019 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1020 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1022 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1024 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1025 prevent compiler warning
1027 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1029 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1030 moved to level 0 and declared as static. Also they are explicit
1031 placed in access bank. This was necessery because some times they
1032 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1033 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1034 optimizations. Currently only compare to unsigned char is implemented,
1035 * src/pic16/gen.c: added fReturnIdx array,
1036 * (struct resolvedIfx) is moved to gen.h and made public,
1037 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1038 * (aopForSym): added an optimization to directly store in stack of
1039 the operand of a SEND iCode,
1040 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1041 but as registers instead (AOP_REG) using the fReturnIdx array,
1042 * (pic16_freeAsmop): remove the freed register from the
1043 _G.sregsAlloc field,
1044 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1045 a compare of 'WREG',
1046 * (pic16_popGetTempRegCond): changed function prototype, now
1047 function takes also a bitVector argument v which holds the current
1048 set of registers that are allocated for stack access by aopForSym,
1049 registers allocated in aopForSym for accessing stack symbols are not
1050 any more part of the functions usedRegs field,
1051 * (genCall): some times aopOp is called for a stack variable to be
1052 send, aopForSym might perform the push, if this is true make sure
1053 that genCall doesn't push the variable twice by testing _G.resDirect,
1054 * (genFunction): changed testing for unspecified interrupt number
1055 from 256 to INTNO_UNSPEC,
1056 * modified selection scheme of frame pointer generation. Previously
1057 if function did use local registers a frame pointer was generated,
1058 now a frame pointer is generated only if function has arguments
1059 (that need PLUSW2 register access), or has stack arguments, or the
1060 compiler is not instructed to omit the frame pointer,
1061 * (genEndFunction): before restoring local registers that were saved
1062 in the function preamble, also restore the registers that *might*
1063 have been allocated for stack access,
1064 * (genRet): removed some old comments,
1065 * (genCmp, the active (RN's) version): added a call to the
1066 pic16_genCmp_special function to perform the compare with a more
1067 robust and optimized way,
1068 * (genInline): a feature has been added in inline code generation,
1069 which allows a wildcard variable substitution when writing inline
1070 assembly. Code is incomplete and experimental therefore undocumented,
1071 * (genCast): changed order of aopOp for result and right to allow
1072 aopForSym to directly load the result if possible,
1073 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1074 perform an optimized compare on some selected special occasions,
1075 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1076 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1077 generate an IVT any more,
1078 * src/pic16/main.c (pic16_optionsTable): added command line option
1080 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1081 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1083 * src/pic16/NOTES: Raphael Neider added in list of active developers
1084 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1085 jumptable_end to prevent bug #,
1086 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1087 inCond and outCond fields,
1088 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1089 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1090 turn off register spilling,
1091 * (packRegsForOneUse): synced with other ports' versions although it
1092 is not used currently,
1093 * (pic16_packRegisters): added an optimization while reading
1094 structure bitfields, some registers may be saved (malloc code is
1095 decreased by 80 bytes)
1097 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1099 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1100 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1101 this can be optimized more?
1103 2005-03-10 Raphael Neider <rneider AT web.de>
1105 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1106 genNearPointerGet): (hopefully) fixed access to bitfields via
1107 pointers (p->bitN = x; and x = p->bitN; failed)
1109 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1286 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1287 (sizeof(sectNames) changed to sizeof(sectName))

1295 of (byte sized) temporaries (assign them to WREG for now)
1296 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1297 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1298 this might fix SIGSEGVs on MinGW...
1299 * src/SDCCopt.c (killDeadCode): restored original behaviour
1300 (volatile operands might get thrown away though)
1302 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1304 * src/pic16/gen.c: fixed bug #1106975,

1758 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1760 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
1763 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
1765 * src/pic16/device.h,
1766 * src/pic16/genarith.c,
1769 * src/pic16/pcode.c: applied patches #1068154 and #1070213
1771 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1773 Large cummulative patch for pic16 port.
1774 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1775 to call when a stack overflow occurs,
1776 * (malloc.h): added CVS Id tag,
1777 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1779 * added libc directory. The current version of LibC contains string
1780 functions, ctype functions and macros and some functions of the
1781 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1782 be extensively tested in the future. Standard disclaimer here.
1783 Library is not automatically build yet. But one can build it by
1784 invoking 'make' inside the libc directory.
1785 * added ADC library under libio. Preliminary version yet.
1787 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1788 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1789 aopForRemat() now and not by pic16_aopOp(),
1790 * (pic16_popGetTempReg): removed warning messgae when allocating
1791 temporary registers, its a buggy feature and will be removed,
1792 * (pic16_popGet): set register instance field in AOP_CRY,
1793 * (pic16_outBitC): fixed for results in size greater than 1,
1794 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1795 * (pic16_storeForReturn): optimized return of 0,
1796 * (genCmp): experimental code for new genCmp which uses PIC18's
1797 special compare&skip instructions. Initial tests fail some times
1798 with variables grater than 1 byte in size, so new code is disabled,
1799 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1801 * (genCast): began a fix to optimize the casting of a bit to another
1802 bit, now assigning a bitfield to another bitfield will fail, sorry,
1803 * src/pic16/main.c: disabled the use of lr-support feature,
1804 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1805 * added some function prototypes, added function _debugf prototype,
1806 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1807 bits with offset (case PO_GPR_BIT),
1808 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1810 * (isBankInstruction): modified to return 0 for no banking instruction,
1811 and 1 for banking instruction,
1812 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1813 caused stop processing pCodes after a inline assembly block,
1814 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1815 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1816 registers when it shouldn't,
1817 * src/pic16/ralloc.c (allocReg): add preliminary support for
1818 supporting a limited set of temporary registers,
1820 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1822 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1823 genDataPointerSet): ensure assignments always copy in MSB to LSB
1825 (loadRegFromAop): recognize CLRH optimization,
1826 (genFunction): optimize RECEIVE iCodes in reentrant functions
1828 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1830 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1831 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1833 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1844 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

4825 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4827 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4828 loaded with the linker search paths (-L arguments) and the libraries
4829 to be linked with the current source (-l arguments). Changes
4830 currently will affect only the pic16 port.
4831 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4832 include path the port specific paths and port specific libraries,
4833 * gplink command now contains the $3 argument,
4834 * src/pic16/device.h,
4835 * src/pic16/device.c,: structure PIC_device is made public and
4836 renamed to PIC16_device, the same for variable Pics which is renamed

4851 Documenting changes from previous commits.
4852 * configure.in (version 1.56),
4853 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4854 when generating output files to configure the pic16 library,
4855 but now I've commented it out, since gputils aren't installed in the
4856 SF compile farm, so library won't compile
4858 * device/lib/Makefile.in (version 1.56): initially I've added in
4859 target 'all' the prerequestive 'model-pic16' so it compiled the
4860 pic16 library, but now I've commented it out for the same reasons
4862 * added targets 'model-pic16' and 'objects-pic16' to compile the
4864 * added target 'port-specific-objects-pic16' to handle the
4865 generated libraries and copy them into the build/ directory
4866 * added target 'clean-intermediate-pic16' to clean intermediate
4867 files into pic16 directory
4868 * in target 'installdirs' added line to create directory pic16 in

4889 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4890 option so that it actually works. Made it specific to the z80, since
4891 the gbz80 doesn't have these kinds of I/O ports.
4893 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4895 * device/include/z180.h,

4919 via literal number. The symbol is placed in the corresponding
4920 position of the data ram
4921 * (pic16_dump_section): relocatable and absolute uninitialized
4922 data are now emitted in sorted order to reduce section naming,
4923 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4924 weren't marked as being in the access bank,
4926 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4928 Added portion of GNU PIC Library under the directory
4929 device/include/pic16 and device/lib/pic16. These files
4930 contain the declarations of SFRs for the PIC18Fxx2 devices.
4931 The directory is initialized via configure from toplevel.
4933 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4935 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4961 all over. Telling LaTeX to be less strict with word spacing
4962 to better keep the right margin. Changed some notes about
4963 maintainance of the ports in section 3.2.1 - is it OK like this?
4965 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5003 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5005 * src/pic16/peeph.def: all peepholes with movff are commented out,
5006 because there is a problem in the pcode peep optimizer,
5007 * src/pic16/ralloc.c: the register allocator can now reuse local

5044 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5047 * src/z80/main.c: added missed needLinkerScript flags (more than
5048 one port structure defined in these file)
5049 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5100 include information about variables allocated to the overlay
5103 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5105 * as/mcs51/lkmain.c: Help about -Y option

5117 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5119 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5120 (default behaviour).
5122 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5124 A python script to validate compiler diagnostic messages. It can be
5125 used to verify that sdcc complains about bad c source code and
5126 gives a good location of the error.
5127 * support/valdiag/Makefile,
5128 * support/valdiag/valdiag.py,
5129 * support/valdiag/tests/*
5131 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5144 * src/common.h: added ifndef/define/endif macros
5145 around the header file.
5146 Bug reported from Jesus Calvino-Fraga
5148 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5150 * sdcc.spec: updated
5151 * device/include/Makefile.in: don't install CVS directories
5152 * device/lib/Makefile.in: added removal of CVS directories after install
5153 * doc/Makefile: fixed install, added local_icons
5154 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5155 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5156 * src/ds390/gen.c (genRightShift): fixed bug #870788
5157 * src/SDCCast.c (decorateType): fixed bug #870781
5159 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5161 PIC16 port related changes:
5162 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5163 added variable stackPos,
5165 * gen.c: genCall, assignResultValue: added support for
5166 pushing/retrieving function parameters to/from stack,
5167 genFunction,genEndFunction: setup stack frame for the
5169 genAddrOf: will be changed according to bug 863624
5171 * added files genutils.c and genutils.h which contain gen*
5172 debugged and optimised functions extracted from gen.c
5174 * glue.c: added variable 'externs' which holds extern symbols,
5175 pic16emitRegularMap: is modified to properly handle relocatable
5176 symbols under the new scheme,
5177 pic16createInterruptVect: is modified
5178 pic16printPublics: is modified to emit 'global' assembler directives,
5179 added pic16_printExterns to print extern symbols,
5180 pic16glue: initializes stack/frame pointer in the beginning of
5181 the assembly output. Temporary hack, will be corrected later,
5182 because gplink yet does not support stack and SDCC does not
5183 yet support a type of crt0.o object to create the final binary.
5185 * Removed many lines that contain 8051 legacy code.
5186 * The code is finally placed under a 'code' directive.
5187 * Added port specific options.
5189 * _process_pragma: simplified since now we do not need *special*
5190 include file to define SFR registers. But a separate header
5191 will be needed. This will be developed later.
5192 * _pic16_parseOptions: added, parses port specific options:
5193 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5194 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5195 --preplace-udata-with=
5197 * _pic16_setDefaultOptions: modified to initialize section names,
5198 but hack is temporarly out of order since it needs improvement.
5199 * _pic16_genAssemblerPreamble: configuration words are emitted by
5200 their address instead of their name. This part is incomplete and
5201 supports only the 18Fxx2 devices. Other devices will emit an error
5202 during assembly since they do not contain the same set of config
5204 * _pic16_genIVT: is modified,
5206 * pcode.c: added definitions for some hardware registers that are needed
5208 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5209 All PCI entries are updated. Now LFSR is supported.
5210 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5211 * added pic16_newpCodeOpLit2 to support instructions with
5212 two literal arguments
5213 * pic16_pCode2str: corrected code that emits assembler instructions
5214 with two literal operands and those that have an access bit modifier
5215 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5216 this fixes a bug which caused some labels to be lost, when an
5217 assembler directive was added, i.e. banksel,
5218 * pic16_FixRegisterBanking: improved logic that causes the insertion
5220 * InlineFunction: functions that are called once, are not any more
5221 inlined. This can be a port option in the future,
5223 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5225 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5226 hold the corresponding uninitialized symbols,
5227 * pic16_allocProcessorRegister: registers have explicit marked the
5229 * pic16_allocInternalRegister: registers are explicit marked as
5231 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5232 processing list, so bit registers were lost,
5235 * ralloc.h: added field 'accessBank' and original symbol operand
5236 in register definition,
5237 * removed the field isMapped from register definition,
5239 ** Several functions have been removed from various sources:
5240 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5241 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5242 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5243 pic16_assignRelocatableRegisters
5245 ** others have been introduced:
5246 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5247 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5249 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5251 * support/scripts/inc2h.pl: changed definition of BIT_AT
5252 to emit 'sbit at' instead of 'bit at'. This was a request.
5254 PIC16 port related preliminary changes:
5255 * gen.c: prefixed function popRegFromString with
5256 pic16_ and all references to it corrected
5257 * pcode.c: all pic16_pc_* hardware registers prefixed
5258 with underscore (_),
5259 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5260 * ralloc.c: newReg(): when register is REG_SFR then
5261 set address to rIdx,
5262 pic16_allocProcessorRegister(): marks register wasUsed=0
5263 pic16_writeUsedRegs(): added a call to assign processor
5264 registers via pic16_assignFixedRegisters
5266 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5268 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5269 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5270 variables in unused register banks. Also the SSEG is placed
5271 wherever there is enough space for it, and IDATA can be anywhere
5272 in internal RAM. For now compile using -Wl-Y[stack_size].
5273 The mem file is different for this option as well, since it
5274 makes no sense of talking about DSEG lenght.
5276 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5278 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5279 in certain cases, e.g. when ROM assignment, patch provided
5280 from Albert den Haan.
5282 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5827 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5829 Fixed a number of problems revealed by bug #827883.
5830 * src/SDCCloop.c (loopInvariants): Spill location of the
5831 result operand should be recomputed if extracted from
5832 a loop. Also, don't extract assignments of an iTemp

5835 not occur if the control variable is involved with a
5836 relational operator.

6325 A few small changes that speed up the peephole optimizer.
6329 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6331 Try to make the peephole optimizer smarter by maintaining
6332 an association between the assembly source code and the
6333 iCodes that originated them. Put this information to use
6334 with a new peephole rule condition "notVolatile" so that
6335 the rules can be aggressive yet still safe.
6340 * src/mcs51/peeph.def
6342 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6352 Changed the type of the result of the ! (NOT) operator to char;
6353 previously it returned the same type as the source. This allows
6354 us to eliminate all the genFloatNot functions (all of its target
6355 implementations were very buggy) since !float can use the same

6367 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6368 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6369 during interrupts. Ensure WSAVE is located at a shared bank address.
6370 2. Fixed page selection in some places
6371 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6372 the registers name strings.
6373 4. Fixed "signed / unsigned compare" compiler warnings.
6374 5. The PIC port manages its own allocation of the general purpose
6375 registers, but makes no attempt to reuse them. As a result when
6376 compiling it soon runs out of general purpose registers. Some
6377 additional code was added to the files pcode.c and device.c to walk
6378 through the function call tree and rename the registers so that they
6388 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6395 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6397 Made bitfield a distinct type from bit so that bitfields
6398 convert as per ANSI C and bits retain their traditional
6399 boolean style behaviour. Implemented bitfield support in
6407 * src/ds390/gen.c: bit v bitfield split
6408 * src/z80/gen.c: New support for bitfields
6409 * support/regression/tests/bitfields.c: reenabled z80,
6412 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6414 Rules 246.x, 247.x relate to bitfields, the others speed up
6415 access to xdata mapped I/O devices.
6417 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6419 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6421 Cleaned up genPackBits and genUnpackBits and added two helper
6422 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6423 for literal assignments in genPackBits (thanks to Frieder for
6429 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6431 Fixed bug #748310 (pointer to function type mishandled when the
6432 function name is omitted). Also fixed a SIGSEGV when a function
6433 attribute (reentrant, etc) is used on a non-function or on a
6434 function but misplaced before the parameter list.

6461 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6463 Made the constant following the "interrupt" keyword optional. If
6464 omitted, the function will not automatically be given an entry
6465 in the interrupt vector table (similar to #pragma NOIV, but
6466 less syntacticly kludgy). The interrupt number is also now
6467 range checked. Also fixed a bug in the high order bit example

6943 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6944 the regression tests I'm not brave enough to enable 245.b, 245.c
6945 * doc/sdccman.lyx: added latex preamble for hyperref package.
6946 Using pdflatex this will give you a hyperlinked pdf file with

6988 it can be defined with CFLAGS when running configure
6989 * src/SDCCmain.c: fixed compiling + linking with object files
6991 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6994 added --disable-pic16-port
6995 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6996 * src/SDCCmain.c: linkOptions is changed to set *,
6997 added if/endif conditional macros to remove options help
6998 messages from optionsTable when a port is not configured, added
6999 support for the PIc16 port in the ports table, when executing
7000 the compiler with no port specified on command line, a default
7001 port is selected with the new macro DEFAULT_PORT which is
7002 defined in port.h, in setDefaultOptions() linkOptions is removed
7003 from initialization assignment, since now it is a set,
7004 parseCmdLine uses setParseWithComma for linkOptions, in
7005 linkEdit() linkOptions are accessed with new function indexSet()
7006 which returns the i'th item of a set variable. See SDCCset.c, in
7007 linkEdit() when calling buildCmdLine(), added linkOptions as
7008 last argument. Now users can pass arguments to gplink via the
7009 -Wl option, main() uses pic16glue() to glue up pic16 programs
7010 * src/SDCCpeeph.c: various changes to support pic16

7021 * src/pic16/glue.c: commented out some error producing lines
7022 * src/pic16/main.c: __config directives are commented out to stop
7023 gpasm complaining and test the linkage with gplink, _linkCmd and
7024 _asmCmd changed to be more gplink and gpasm friendly
7025 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7026 produced an error when parsed, peep rule 12 is added to utilize
7027 movff, but it is commented out since the pCode does not support
7028 yet a command with 2 address arguments
7030 2003-05-18 <johan AT balder>
7032 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7059 2003-05-11 Borut Razem <borut.razem AT siol.net>
7061 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7062 the path of bin directory, so that PATH is the only env. variable, which has to be set
7063 in case of standard installation.

8067 * src/SDCCicode.c: fixed array add
8069 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8070 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8071 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8073 2003-01-04 <johan AT balder>
8075 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8077 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8078 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8090 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8091 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8093 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8095 * in \sdcc\as\mcs51\ changed these files in order to create an
8096 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8097 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8098 following files to include the previous two files: aslink.dsp,
8099 Makefile.aslink, Makefile.bcc, and Makefile.in.
8101 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8102 .adb instead of .cdb
8104 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8106 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8107 value from option --iram-size.
8109 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8111 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8114 2002-09-18 <wiml AT hhhh.org>
8116 * SDCClrange.h: exposed setFromRange() and setToRange()
8117 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8118 packRegsForAccUse() (bug 542397)
8119 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8120 multiple times and emitting the fetch operations more than once
8121 added aopGetUsesAcc() function to allow binary operators to
8122 fetch their operands in the correct order; made genMinus() emit
8123 compact code for X = LITERAL - Y
8125 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8126 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8127 sprintf() in line 1267.
8129 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8130 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8133 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8134 Changes to aslink (All the changes are marked with 'JCF'):
8136 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8139 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8140 area BSEG. Also moves, if possible, the DATA area down into the internal
8141 ram so more space is available.
8143 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8146 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8147 not bytes. Function summary() which creates a memory usage summary
8148 file with extension .mem. Reports of overlaping stack and small stack
8149 size. If the space for the stack is less than 16 bytes aslink trows a
8152 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8153 the 8051. Option 'y' for memory summary output file.
8155 Changes to sdcc (All the changes are marked with 'JCF'):
8157 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8159 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8160 overlaying area for it (uses RegBankUsed[4]).
8162 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8163 bank zero as used by default. By default aslink locates the stack
8164 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8165 the creation of the .mem file. Delegates the allocation of data area
8166 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8167 the begining of the stack area to aslink.
8169 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8170 glue() in SDCCglue.c creates an area for it.
8172 2002-09-03 Borut Razem <borut.razem AT siol.net>
8173 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8174 sdcc/src/pic/glue.c:
8175 introduced atexit() handler for teporay files removal in case of
8176 errors, assertions, ...
8178 2002-08-29 Borut Razem <borut.razem AT siol.net>
8179 * sdcc/support/cpp2/auto-host_vc_in.h:
8180 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8181 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8182 Maybe there is a similar problem with BORLANDC? It should be checked!
8184 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8185 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8186 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8187 was not executed, and the compiler (cl) launched a warning:
8188 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8190 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8191 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8193 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8194 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8196 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8197 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

8199 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8200 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8201 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8202 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8203 - added Release configuration in VS projects
8204 - review of compiler an linker options
8205 - VC .exe files are generated in bin_vc directory, not to interfere
8206 with binaries generated from other projects (cygwin, mingw, bcc ...)
8208 * sdcc/src/yacc.dsp: added
8210 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8211 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8212 and insert the version number definitions from .version
8214 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8216 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8217 added - genarate auto-host.h using auto-host_vc_in.h as template
8220 removed from CVS, generated automatically
8222 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8223 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8225 2002-08-11 Borut Razem <borut.razem AT siol.net>
8226 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8228 2002-08-10 Borut Razem <borut.razem AT siol.net>
8229 * src/SDCCmain.c (main):
8230 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8231 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8232 The consequence was that some temporary files were not removed.
8235 unification of code in functions tempfilename() and tempfile():
8236 function tempnam() is defined in Visual Studio 6.0 and .NET
8238 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8240 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8241 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8242 - removed compiler command line option /WX: Treats all warnings as errors
8243 - update a list of source files, included into the project
8245 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8246 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
