930 on rIfx (genCmp was broken)
932 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
934 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
935 * src/z80/main.c (_keywords[]),
936 * src/SDCCglobal.h (struct options),
938 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
939 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
940 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
941 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
942 always available in leading double underscore form. The C99 support is
943 mostly missing, but it's a start.
944 * support/regression/tests/bug-227710.c: fixed nonconforming use of
945 reserved identifier "__data".
947 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

993 2005-03-20 Borut Razem <borut.razem AT siol.net>
995 * support/scripts/inc2h.pl: WIN32 port

1023 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1025 * device/lib/printf_large.c: removed inline assembly for portability and
1026 readability. Use printf_fast if speed or size are more important.
1027 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1028 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1030 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1032 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1033 prevent compiler warning
1035 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1037 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1038 moved to level 0 and declared as static. Also they are explicit
1039 placed in access bank. This was necessery because some times they
1040 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1041 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1042 optimizations. Currently only compare to unsigned char is implemented,
1043 * src/pic16/gen.c: added fReturnIdx array,
1044 * (struct resolvedIfx) is moved to gen.h and made public,
1045 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1046 * (aopForSym): added an optimization to directly store in stack of
1047 the operand of a SEND iCode,
1048 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1049 but as registers instead (AOP_REG) using the fReturnIdx array,
1050 * (pic16_freeAsmop): remove the freed register from the
1051 _G.sregsAlloc field,
1052 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1053 a compare of 'WREG',
1054 * (pic16_popGetTempRegCond): changed function prototype, now
1055 function takes also a bitVector argument v which holds the current
1056 set of registers that are allocated for stack access by aopForSym,
1057 registers allocated in aopForSym for accessing stack symbols are not
1058 any more part of the functions usedRegs field,
1059 * (genCall): some times aopOp is called for a stack variable to be
1060 send, aopForSym might perform the push, if this is true make sure
1061 that genCall doesn't push the variable twice by testing _G.resDirect,
1062 * (genFunction): changed testing for unspecified interrupt number
1063 from 256 to INTNO_UNSPEC,
1064 * modified selection scheme of frame pointer generation. Previously
1065 if function did use local registers a frame pointer was generated,
1066 now a frame pointer is generated only if function has arguments
1067 (that need PLUSW2 register access), or has stack arguments, or the
1068 compiler is not instructed to omit the frame pointer,
1069 * (genEndFunction): before restoring local registers that were saved
1070 in the function preamble, also restore the registers that *might*
1071 have been allocated for stack access,
1072 * (genRet): removed some old comments,
1073 * (genCmp, the active (RN's) version): added a call to the
1074 pic16_genCmp_special function to perform the compare with a more
1075 robust and optimized way,
1076 * (genInline): a feature has been added in inline code generation,
1077 which allows a wildcard variable substitution when writing inline
1078 assembly. Code is incomplete and experimental therefore undocumented,
1079 * (genCast): changed order of aopOp for result and right to allow
1080 aopForSym to directly load the result if possible,
1081 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1082 perform an optimized compare on some selected special occasions,
1083 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1084 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1085 generate an IVT any more,
1086 * src/pic16/main.c (pic16_optionsTable): added command line option
1088 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1089 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1091 * src/pic16/NOTES: Raphael Neider added in list of active developers
1092 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1093 jumptable_end to prevent bug #,
1094 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1095 inCond and outCond fields,
1096 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1097 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1098 turn off register spilling,
1099 * (packRegsForOneUse): synced with other ports' versions although it
1100 is not used currently,
1101 * (pic16_packRegisters): added an optimization while reading
1102 structure bitfields, some registers may be saved (malloc code is
1103 decreased by 80 bytes)
1105 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1107 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1108 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1109 this can be optimized more?
1111 2005-03-10 Raphael Neider <rneider AT web.de>
1113 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1114 genNearPointerGet): (hopefully) fixed access to bitfields via
1115 pointers (p->bitN = x; and x = p->bitN; failed)
1117 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1294 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1295 (sizeof(sectNames) changed to sizeof(sectName))
1296 Both patches fix segfaults under MinGW.

1303 of (byte sized) temporaries (assign them to WREG for now)
1304 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1305 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1306 this might fix SIGSEGVs on MinGW...
1307 * src/SDCCopt.c (killDeadCode): restored original behaviour
1308 (volatile operands might get thrown away though)
1310 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1312 * src/pic16/gen.c: fixed bug #1106975,

1749 Adding support for replacing ljmps with sjmps in jumptables
1750 generated for switch statements. For now you need to set the
1751 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1752 Now 4 algorithms for mcs51 jumptable generation are used:
1753 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1781 Large cummulative patch for pic16 port.
1782 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1783 to call when a stack overflow occurs,
1784 * (malloc.h): added CVS Id tag,
1785 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1787 * added libc directory. The current version of LibC contains string
1788 functions, ctype functions and macros and some functions of the
1789 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1790 be extensively tested in the future. Standard disclaimer here.
1791 Library is not automatically build yet. But one can build it by
1792 invoking 'make' inside the libc directory.
1793 * added ADC library under libio. Preliminary version yet.
1795 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1796 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1797 aopForRemat() now and not by pic16_aopOp(),

1803 * (pic16_storeForReturn): optimized return of 0,
1804 * (genCmp): experimental code for new genCmp which uses PIC18's
1805 special compare&skip instructions. Initial tests fail some times
1806 with variables grater than 1 byte in size, so new code is disabled,
1807 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1809 * (genCast): began a fix to optimize the casting of a bit to another
1810 bit, now assigning a bitfield to another bitfield will fail, sorry,
1811 * src/pic16/main.c: disabled the use of lr-support feature,
1812 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1813 * added some function prototypes, added function _debugf prototype,
1814 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1815 bits with offset (case PO_GPR_BIT),
1816 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1818 * (isBankInstruction): modified to return 0 for no banking instruction,
1819 and 1 for banking instruction,
1820 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1821 caused stop processing pCodes after a inline assembly block,
1822 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1823 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1824 registers when it shouldn't,
1825 * src/pic16/ralloc.c (allocReg): add preliminary support for
1826 supporting a limited set of temporary registers,
1828 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1830 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1831 genDataPointerSet): ensure assignments always copy in MSB to LSB
1833 (loadRegFromAop): recognize CLRH optimization,
1834 (genFunction): optimize RECEIVE iCodes in reentrant functions
1836 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1838 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1839 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4836 loaded with the linker search paths (-L arguments) and the libraries
4837 to be linked with the current source (-l arguments). Changes
4838 currently will affect only the pic16 port.
4839 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4840 include path the port specific paths and port specific libraries,
4841 * gplink command now contains the $3 argument,
4842 * src/pic16/device.h,

4859 Documenting changes from previous commits.
4860 * configure.in (version 1.56),
4861 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4862 when generating output files to configure the pic16 library,
4863 but now I've commented it out, since gputils aren't installed in the
4864 SF compile farm, so library won't compile
4866 * device/lib/Makefile.in (version 1.56): initially I've added in
4867 target 'all' the prerequestive 'model-pic16' so it compiled the
4868 pic16 library, but now I've commented it out for the same reasons
4870 * added targets 'model-pic16' and 'objects-pic16' to compile the
4872 * added target 'port-specific-objects-pic16' to handle the
4873 generated libraries and copy them into the build/ directory
4874 * added target 'clean-intermediate-pic16' to clean intermediate
4875 files into pic16 directory
4876 * in target 'installdirs' added line to create directory pic16 in
4877 the installation path
4879 * device/include/Makefile.in (version 1.11): in target 'install'
4880 added lines to copy all header files to installation path,
4881 * in target 'installdirs' added line create directory for pic16
4882 headers in the installation path
4884 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4897 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4898 option so that it actually works. Made it specific to the z80, since
4899 the gbz80 doesn't have these kinds of I/O ports.
4901 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4903 * device/include/z180.h,

4916 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4918 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4919 changed interrupt vector table generation to only emit declared vectors.

4921 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4923 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4925 Mainly changes to support compilation of the device libraries
4926 * src/pic16/device.c: stack is allocated via symbol and not
4927 via literal number. The symbol is placed in the corresponding
4928 position of the data ram
4929 * (pic16_dump_section): relocatable and absolute uninitialized
4930 data are now emitted in sorted order to reduce section naming,
4931 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4932 weren't marked as being in the access bank,
4934 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4936 Added portion of GNU PIC Library under the directory
4937 device/include/pic16 and device/lib/pic16. These files
4938 contain the declarations of SFRs for the PIC18Fxx2 devices.
4939 The directory is initialized via configure from toplevel.
4941 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4943 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4944 the spilllocations to be compared correctly
4946 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

4968 * doc/sdccman.lyx: Moved and added some sections, small changes
4969 all over. Telling LaTeX to be less strict with word spacing
4970 to better keep the right margin. Changed some notes about
4971 maintainance of the ports in section 3.2.1 - is it OK like this?
4973 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5010 UPPER for immediate operands,
5011 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5013 * src/pic16/peeph.def: all peepholes with movff are commented out,
5014 because there is a problem in the pcode peep optimizer,
5015 * src/pic16/ralloc.c: the register allocator can now reuse local
5016 function symbols for another function. This saves register usage.
5017 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5019 Added file src/pic16/NOTES with information about program writing on
5020 the current port version.

5052 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5055 * src/z80/main.c: added missed needLinkerScript flags (more than
5056 one port structure defined in these file)
5057 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5073 needLinkerScript flag
5075 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5076 * src/pic/glue.c: added variable udata_section_name to
5077 override default uninitialized data segment definition for
5078 devices only with SHAREBANK memory (reported from Erik Epetrich)
5079 * (pic14emitOverlay): modified to emit a commented overlay segment
5080 directive when no overlay data exist
5081 * (picglue): modified to emit uninitialized data segment
5082 according to udata_section_name

5092 2004-01-07 Borut Razem <borut.razem AT siol.net>
5094 * support/scripts/sdcc.nsi: update PATH
5095 * support/scripts/sdcc.ico: craeted

5108 include information about variables allocated to the overlay
5111 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5113 * as/mcs51/lkmain.c: Help about -Y option

5125 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5127 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5128 (default behaviour).
5130 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5132 A python script to validate compiler diagnostic messages. It can be
5133 used to verify that sdcc complains about bad c source code and
5134 gives a good location of the error.
5135 * support/valdiag/Makefile,
5136 * support/valdiag/valdiag.py,
5137 * support/valdiag/tests/*

5154 Bug reported from Jesus Calvino-Fraga
5156 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5158 * sdcc.spec: updated
5159 * device/include/Makefile.in: don't install CVS directories
5160 * device/lib/Makefile.in: added removal of CVS directories after install
5161 * doc/Makefile: fixed install, added local_icons
5162 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5163 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5164 * src/ds390/gen.c (genRightShift): fixed bug #870788
5165 * src/SDCCast.c (decorateType): fixed bug #870781
5167 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5169 PIC16 port related changes:
5170 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5171 added variable stackPos,
5173 * gen.c: genCall, assignResultValue: added support for
5174 pushing/retrieving function parameters to/from stack,
5175 genFunction,genEndFunction: setup stack frame for the
5177 genAddrOf: will be changed according to bug 863624
5179 * added files genutils.c and genutils.h which contain gen*
5180 debugged and optimised functions extracted from gen.c
5182 * glue.c: added variable 'externs' which holds extern symbols,
5183 pic16emitRegularMap: is modified to properly handle relocatable
5184 symbols under the new scheme,
5185 pic16createInterruptVect: is modified
5186 pic16printPublics: is modified to emit 'global' assembler directives,
5187 added pic16_printExterns to print extern symbols,
5188 pic16glue: initializes stack/frame pointer in the beginning of
5189 the assembly output. Temporary hack, will be corrected later,
5190 because gplink yet does not support stack and SDCC does not
5191 yet support a type of crt0.o object to create the final binary.
5193 * Removed many lines that contain 8051 legacy code.
5194 * The code is finally placed under a 'code' directive.
5195 * Added port specific options.
5197 * _process_pragma: simplified since now we do not need *special*
5198 include file to define SFR registers. But a separate header
5199 will be needed. This will be developed later.
5200 * _pic16_parseOptions: added, parses port specific options:
5201 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5202 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5203 --preplace-udata-with=
5205 * _pic16_setDefaultOptions: modified to initialize section names,
5206 but hack is temporarly out of order since it needs improvement.
5207 * _pic16_genAssemblerPreamble: configuration words are emitted by
5208 their address instead of their name. This part is incomplete and
5209 supports only the 18Fxx2 devices. Other devices will emit an error
5210 during assembly since they do not contain the same set of config
5212 * _pic16_genIVT: is modified,
5214 * pcode.c: added definitions for some hardware registers that are needed
5216 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5217 All PCI entries are updated. Now LFSR is supported.
5218 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5219 * added pic16_newpCodeOpLit2 to support instructions with
5220 two literal arguments
5221 * pic16_pCode2str: corrected code that emits assembler instructions
5222 with two literal operands and those that have an access bit modifier
5223 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5224 this fixes a bug which caused some labels to be lost, when an
5225 assembler directive was added, i.e. banksel,
5226 * pic16_FixRegisterBanking: improved logic that causes the insertion
5228 * InlineFunction: functions that are called once, are not any more
5229 inlined. This can be a port option in the future,
5231 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5233 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5234 hold the corresponding uninitialized symbols,
5235 * pic16_allocProcessorRegister: registers have explicit marked the
5237 * pic16_allocInternalRegister: registers are explicit marked as
5239 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5240 processing list, so bit registers were lost,
5243 * ralloc.h: added field 'accessBank' and original symbol operand
5244 in register definition,
5245 * removed the field isMapped from register definition,
5247 ** Several functions have been removed from various sources:
5248 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5249 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5250 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5251 pic16_assignRelocatableRegisters
5253 ** others have been introduced:
5254 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5255 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5257 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5259 * support/scripts/inc2h.pl: changed definition of BIT_AT
5260 to emit 'sbit at' instead of 'bit at'. This was a request.
5262 PIC16 port related preliminary changes:
5263 * gen.c: prefixed function popRegFromString with
5264 pic16_ and all references to it corrected
5265 * pcode.c: all pic16_pc_* hardware registers prefixed
5266 with underscore (_),
5267 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5268 * ralloc.c: newReg(): when register is REG_SFR then
5269 set address to rIdx,
5270 pic16_allocProcessorRegister(): marks register wasUsed=0
5271 pic16_writeUsedRegs(): added a call to assign processor
5272 registers via pic16_assignFixedRegisters
5274 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5276 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5277 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5278 variables in unused register banks. Also the SSEG is placed
5279 wherever there is enough space for it, and IDATA can be anywhere
5280 in internal RAM. For now compile using -Wl-Y[stack_size].
5281 The mem file is different for this option as well, since it
5282 makes no sense of talking about DSEG lenght.
5284 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5286 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5287 in certain cases, e.g. when ROM assignment, patch provided
5288 from Albert den Haan.
5290 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6333 A few small changes that speed up the peephole optimizer.
6337 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6339 Try to make the peephole optimizer smarter by maintaining
6340 an association between the assembly source code and the
6341 iCodes that originated them. Put this information to use
6342 with a new peephole rule condition "notVolatile" so that
6343 the rules can be aggressive yet still safe.
6348 * src/mcs51/peeph.def
6350 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6354 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6355 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6356 if the left or right operand symbols have the accuse flag set.
6358 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6360 Changed the type of the result of the ! (NOT) operator to char;
6361 previously it returned the same type as the source. This allows
6362 us to eliminate all the genFloatNot functions (all of its target
6363 implementations were very buggy) since !float can use the same
6366 * src/SDCCicode.c (ast2iCode): ! returns char

6375 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6376 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6377 during interrupts. Ensure WSAVE is located at a shared bank address.
6378 2. Fixed page selection in some places
6379 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6380 the registers name strings.
6381 4. Fixed "signed / unsigned compare" compiler warnings.
6382 5. The PIC port manages its own allocation of the general purpose
6383 registers, but makes no attempt to reuse them. As a result when
6384 compiling it soon runs out of general purpose registers. Some
6385 additional code was added to the files pcode.c and device.c to walk
6386 through the function call tree and rename the registers so that they
6396 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6403 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6405 Made bitfield a distinct type from bit so that bitfields
6406 convert as per ANSI C and bits retain their traditional
6407 boolean style behaviour. Implemented bitfield support in
6415 * src/ds390/gen.c: bit v bitfield split
6416 * src/z80/gen.c: New support for bitfields
6417 * support/regression/tests/bitfields.c: reenabled z80,
6420 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6422 Rules 246.x, 247.x relate to bitfields, the others speed up
6423 access to xdata mapped I/O devices.
6425 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6427 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6429 Cleaned up genPackBits and genUnpackBits and added two helper
6430 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6431 for literal assignments in genPackBits (thanks to Frieder for
6437 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6439 Fixed bug #748310 (pointer to function type mishandled when the
6440 function name is omitted). Also fixed a SIGSEGV when a function
6441 attribute (reentrant, etc) is used on a non-function or on a
6442 function but misplaced before the parameter list.

6469 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6471 Made the constant following the "interrupt" keyword optional. If
6472 omitted, the function will not automatically be given an entry
6473 in the interrupt vector table (similar to #pragma NOIV, but
6474 less syntacticly kludgy). The interrupt number is also now
6475 range checked. Also fixed a bug in the high order bit example

6496 unsigned, but are signed by default
6497 * src/SDCCval.c (constVal): rearranged
6498 * src/SDCCval.c (valMod): preliminary fix
6499 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6951 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6952 the regression tests I'm not brave enough to enable 245.b, 245.c
6953 * doc/sdccman.lyx: added latex preamble for hyperref package.
6954 Using pdflatex this will give you a hyperlinked pdf file with

6997 * src/SDCCmain.c: fixed compiling + linking with object files
6999 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7002 added --disable-pic16-port
7003 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7004 * src/SDCCmain.c: linkOptions is changed to set *,
7005 added if/endif conditional macros to remove options help
7006 messages from optionsTable when a port is not configured, added
7007 support for the PIc16 port in the ports table, when executing
7008 the compiler with no port specified on command line, a default
7009 port is selected with the new macro DEFAULT_PORT which is
7010 defined in port.h, in setDefaultOptions() linkOptions is removed
7011 from initialization assignment, since now it is a set,
7012 parseCmdLine uses setParseWithComma for linkOptions, in
7013 linkEdit() linkOptions are accessed with new function indexSet()
7014 which returns the i'th item of a set variable. See SDCCset.c, in
7015 linkEdit() when calling buildCmdLine(), added linkOptions as
7016 last argument. Now users can pass arguments to gplink via the
7017 -Wl option, main() uses pic16glue() to glue up pic16 programs
7018 * src/SDCCpeeph.c: various changes to support pic16

7029 * src/pic16/glue.c: commented out some error producing lines
7030 * src/pic16/main.c: __config directives are commented out to stop
7031 gpasm complaining and test the linkage with gplink, _linkCmd and
7032 _asmCmd changed to be more gplink and gpasm friendly
7033 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7034 produced an error when parsed, peep rule 12 is added to utilize
7035 movff, but it is commented out since the pCode does not support
7036 yet a command with 2 address arguments
7038 2003-05-18 <johan AT balder>
7040 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7065 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7067 2003-05-11 Borut Razem <borut.razem AT siol.net>
7069 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7070 the path of bin directory, so that PATH is the only env. variable, which has to be set
7071 in case of standard installation.
7072 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8075 * src/SDCCicode.c: fixed array add
8077 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8078 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8079 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8081 2003-01-04 <johan AT balder>
8083 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8085 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8086 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8098 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8099 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8101 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8103 * in \sdcc\as\mcs51\ changed these files in order to create an
8104 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8105 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8106 following files to include the previous two files: aslink.dsp,
8107 Makefile.aslink, Makefile.bcc, and Makefile.in.
8109 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8110 .adb instead of .cdb
8112 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8114 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8115 value from option --iram-size.
8117 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8119 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8122 2002-09-18 <wiml AT hhhh.org>
8124 * SDCClrange.h: exposed setFromRange() and setToRange()
8125 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8126 packRegsForAccUse() (bug 542397)
8127 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8128 multiple times and emitting the fetch operations more than once
8129 added aopGetUsesAcc() function to allow binary operators to
8130 fetch their operands in the correct order; made genMinus() emit
8131 compact code for X = LITERAL - Y
8133 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8134 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8135 sprintf() in line 1267.
8137 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8138 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8141 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8142 Changes to aslink (All the changes are marked with 'JCF'):
8144 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8147 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8148 area BSEG. Also moves, if possible, the DATA area down into the internal
8149 ram so more space is available.
8151 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8154 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8155 not bytes. Function summary() which creates a memory usage summary
8156 file with extension .mem. Reports of overlaping stack and small stack
8157 size. If the space for the stack is less than 16 bytes aslink trows a
8160 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8161 the 8051. Option 'y' for memory summary output file.
8163 Changes to sdcc (All the changes are marked with 'JCF'):
8165 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8167 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8168 overlaying area for it (uses RegBankUsed[4]).
8170 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8171 bank zero as used by default. By default aslink locates the stack
8172 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8173 the creation of the .mem file. Delegates the allocation of data area
8174 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8175 the begining of the stack area to aslink.
8177 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8178 glue() in SDCCglue.c creates an area for it.
8180 2002-09-03 Borut Razem <borut.razem AT siol.net>
8181 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8182 sdcc/src/pic/glue.c:
8183 introduced atexit() handler for teporay files removal in case of
8184 errors, assertions, ...
8186 2002-08-29 Borut Razem <borut.razem AT siol.net>
8187 * sdcc/support/cpp2/auto-host_vc_in.h:
8188 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8189 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8190 Maybe there is a similar problem with BORLANDC? It should be checked!
8192 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8193 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8194 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8195 was not executed, and the compiler (cl) launched a warning:
8196 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8198 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8199 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8201 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8202 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8204 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8205 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8206 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8207 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8208 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8209 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8210 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8211 - added Release configuration in VS projects
8212 - review of compiler an linker options
8213 - VC .exe files are generated in bin_vc directory, not to interfere
8214 with binaries generated from other projects (cygwin, mingw, bcc ...)
8216 * sdcc/src/yacc.dsp: added
8218 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8219 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8220 and insert the version number definitions from .version
8222 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8224 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8225 added - genarate auto-host.h using auto-host_vc_in.h as template
8228 removed from CVS, generated automatically
8230 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8231 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8233 2002-08-11 Borut Razem <borut.razem AT siol.net>
8234 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8236 2002-08-10 Borut Razem <borut.razem AT siol.net>
8237 * src/SDCCmain.c (main):
8238 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8239 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8240 The consequence was that some temporary files were not removed.
8243 unification of code in functions tempfilename() and tempfile():
8244 function tempnam() is defined in Visual Studio 6.0 and .NET
8246 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8248 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8249 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8250 - removed compiler command line option /WX: Treats all warnings as errors
8251 - update a list of source files, included into the project
8253 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8254 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8255 changed project type to Generic Project so that can be correcly converted to VS.NET project

8267 added newline in the def file to keep MSC compiler satisfied
8269 * sdcc/src/z80/gen.c:
8270 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8271 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8272 - solved MSC error in function aopDump()

8451 * sdcc/src/SDCCloop.c:
8452 Previous fix was not good. basic blocks that have "break" or "return" are
8453 not really partof a loop , but live ranges used in these blocks should
8454 be live thru the entire loop, so set partOfLoop but don't add them to
