949 on rIfx (genCmp was broken)
951 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
953 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
954 * src/z80/main.c (_keywords[]),
955 * src/SDCCglobal.h (struct options),
957 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
958 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
959 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
960 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
961 always available in leading double underscore form. The C99 support is
962 mostly missing, but it's a start.
963 * support/regression/tests/bug-227710.c: fixed nonconforming use of
964 reserved identifier "__data".
966 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1012 2005-03-20 Borut Razem <borut.razem AT siol.net>
1014 * support/scripts/inc2h.pl: WIN32 port

1042 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1044 * device/lib/printf_large.c: removed inline assembly for portability and
1045 readability. Use printf_fast if speed or size are more important.
1046 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1047 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1049 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1051 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1052 prevent compiler warning
1054 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1056 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1057 moved to level 0 and declared as static. Also they are explicit
1058 placed in access bank. This was necessery because some times they
1059 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1060 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1061 optimizations. Currently only compare to unsigned char is implemented,
1062 * src/pic16/gen.c: added fReturnIdx array,
1063 * (struct resolvedIfx) is moved to gen.h and made public,
1064 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1065 * (aopForSym): added an optimization to directly store in stack of
1066 the operand of a SEND iCode,
1067 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1068 but as registers instead (AOP_REG) using the fReturnIdx array,
1069 * (pic16_freeAsmop): remove the freed register from the
1070 _G.sregsAlloc field,
1071 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1072 a compare of 'WREG',
1073 * (pic16_popGetTempRegCond): changed function prototype, now
1074 function takes also a bitVector argument v which holds the current
1075 set of registers that are allocated for stack access by aopForSym,
1076 registers allocated in aopForSym for accessing stack symbols are not
1077 any more part of the functions usedRegs field,
1078 * (genCall): some times aopOp is called for a stack variable to be
1079 send, aopForSym might perform the push, if this is true make sure
1080 that genCall doesn't push the variable twice by testing _G.resDirect,
1081 * (genFunction): changed testing for unspecified interrupt number
1082 from 256 to INTNO_UNSPEC,
1083 * modified selection scheme of frame pointer generation. Previously
1084 if function did use local registers a frame pointer was generated,
1085 now a frame pointer is generated only if function has arguments
1086 (that need PLUSW2 register access), or has stack arguments, or the
1087 compiler is not instructed to omit the frame pointer,
1088 * (genEndFunction): before restoring local registers that were saved
1089 in the function preamble, also restore the registers that *might*
1090 have been allocated for stack access,
1091 * (genRet): removed some old comments,
1092 * (genCmp, the active (RN's) version): added a call to the
1093 pic16_genCmp_special function to perform the compare with a more
1094 robust and optimized way,
1095 * (genInline): a feature has been added in inline code generation,
1096 which allows a wildcard variable substitution when writing inline
1097 assembly. Code is incomplete and experimental therefore undocumented,
1098 * (genCast): changed order of aopOp for result and right to allow
1099 aopForSym to directly load the result if possible,
1100 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1101 perform an optimized compare on some selected special occasions,
1102 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1103 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1104 generate an IVT any more,
1105 * src/pic16/main.c (pic16_optionsTable): added command line option
1107 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1108 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1110 * src/pic16/NOTES: Raphael Neider added in list of active developers
1111 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1112 jumptable_end to prevent bug #,
1113 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1114 inCond and outCond fields,
1115 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1116 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1117 turn off register spilling,
1118 * (packRegsForOneUse): synced with other ports' versions although it
1119 is not used currently,
1120 * (pic16_packRegisters): added an optimization while reading
1121 structure bitfields, some registers may be saved (malloc code is
1122 decreased by 80 bytes)
1124 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1126 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1127 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1128 this can be optimized more?
1130 2005-03-10 Raphael Neider <rneider AT web.de>
1132 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1133 genNearPointerGet): (hopefully) fixed access to bitfields via
1134 pointers (p->bitN = x; and x = p->bitN; failed)
1136 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1313 * src/pic16/main.c (_process_pragma): fixed another malloc bug
1314 (sizeof(sectNames) changed to sizeof(sectName))

1322 of (byte sized) temporaries (assign them to WREG for now)
1323 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
1324 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1325 this might fix SIGSEGVs on MinGW...
1326 * src/SDCCopt.c (killDeadCode): restored original behaviour
1327 (volatile operands might get thrown away though)
1329 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
1331 * src/pic16/gen.c: fixed bug #1106975,

1762 2004-12-02 Slade Rich <slade_rich AT users.sourceforge.net>
1764 * device/include/pic/pic16f877.h : added an include file for the PIC16F877 device.
1766 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1768 Adding support for replacing ljmps with sjmps in jumptables
1769 generated for switch statements. For now you need to set the
1770 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1771 Now 4 algorithms for mcs51 jumptable generation are used:
1772 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1773 addresses loaded pc-relative for up to 112 cases and stack-pushing
1774 target addresses loaded with offset from dptr for up to 256 cases.
1776 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1777 * src/mcs51/main.c: adapted constants for switch table generation
1778 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1798 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1800 Large cummulative patch for pic16 port.
1801 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1802 to call when a stack overflow occurs,
1803 * (malloc.h): added CVS Id tag,
1804 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1806 * added libc directory. The current version of LibC contains string
1807 functions, ctype functions and macros and some functions of the
1808 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1809 be extensively tested in the future. Standard disclaimer here.
1810 Library is not automatically build yet. But one can build it by
1811 invoking 'make' inside the libc directory.
1812 * added ADC library under libio. Preliminary version yet.
1814 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1815 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1816 aopForRemat() now and not by pic16_aopOp(),
1817 * (pic16_popGetTempReg): removed warning messgae when allocating
1818 temporary registers, its a buggy feature and will be removed,
1819 * (pic16_popGet): set register instance field in AOP_CRY,
1820 * (pic16_outBitC): fixed for results in size greater than 1,
1821 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1822 * (pic16_storeForReturn): optimized return of 0,
1823 * (genCmp): experimental code for new genCmp which uses PIC18's
1824 special compare&skip instructions. Initial tests fail some times
1825 with variables grater than 1 byte in size, so new code is disabled,
1826 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1828 * (genCast): began a fix to optimize the casting of a bit to another
1829 bit, now assigning a bitfield to another bitfield will fail, sorry,
1830 * src/pic16/main.c: disabled the use of lr-support feature,
1831 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1832 * added some function prototypes, added function _debugf prototype,
1833 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1834 bits with offset (case PO_GPR_BIT),
1835 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1837 * (isBankInstruction): modified to return 0 for no banking instruction,
1838 and 1 for banking instruction,
1839 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1840 caused stop processing pCodes after a inline assembly block,
1841 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1842 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1843 registers when it shouldn't,
1844 * src/pic16/ralloc.c (allocReg): add preliminary support for
1845 supporting a limited set of temporary registers,
1847 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1849 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1850 genDataPointerSet): ensure assignments always copy in MSB to LSB
1852 (loadRegFromAop): recognize CLRH optimization,
1853 (genFunction): optimize RECEIVE iCodes in reentrant functions
1855 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1857 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1858 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1860 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1866 * device/lib/_gptrget.c (_gptrget),
1867 * device/lib/_gptrgetc.c (_gptrgetc),
1868 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1869 instead of sjmp to ret
1870 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1871 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1873 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4855 loaded with the linker search paths (-L arguments) and the libraries
4856 to be linked with the current source (-l arguments). Changes
4857 currently will affect only the pic16 port.
4858 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4859 include path the port specific paths and port specific libraries,
4860 * gplink command now contains the $3 argument,
4861 * src/pic16/device.h,
4862 * src/pic16/device.c,: structure PIC_device is made public and
4863 renamed to PIC16_device, the same for variable Pics which is renamed
4864 to Pics16. Updated all references to them.
4865 * src/pic16/glue.c (pic16glue): corrected bug with code
4866 initialization which bypassed the variable initializations block.
4868 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4869 COMPILE_FLAGS and added the --nostdinc option
4871 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4873 * device/include/mc68hc908jb8.h: Register defs for another member
4874 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4876 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4878 Documenting changes from previous commits.
4879 * configure.in (version 1.56),
4880 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4881 when generating output files to configure the pic16 library,
4882 but now I've commented it out, since gputils aren't installed in the
4883 SF compile farm, so library won't compile
4885 * device/lib/Makefile.in (version 1.56): initially I've added in
4886 target 'all' the prerequestive 'model-pic16' so it compiled the
4887 pic16 library, but now I've commented it out for the same reasons
4889 * added targets 'model-pic16' and 'objects-pic16' to compile the
4891 * added target 'port-specific-objects-pic16' to handle the
4892 generated libraries and copy them into the build/ directory
4893 * added target 'clean-intermediate-pic16' to clean intermediate
4894 files into pic16 directory
4895 * in target 'installdirs' added line to create directory pic16 in
4896 the installation path
4898 * device/include/Makefile.in (version 1.11): in target 'install'
4899 added lines to copy all header files to installation path,
4900 * in target 'installdirs' added line create directory for pic16
4901 headers in the installation path

4916 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4917 option so that it actually works. Made it specific to the z80, since
4918 the gbz80 doesn't have these kinds of I/O ports.
4920 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4922 * device/include/z180.h,

4935 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4937 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4938 changed interrupt vector table generation to only emit declared vectors.
4939 * device/include/Makefile.in: added missing backslash
4940 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

4944 Mainly changes to support compilation of the device libraries
4945 * src/pic16/device.c: stack is allocated via symbol and not
4946 via literal number. The symbol is placed in the corresponding
4947 position of the data ram
4948 * (pic16_dump_section): relocatable and absolute uninitialized
4949 data are now emitted in sorted order to reduce section naming,
4950 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4951 weren't marked as being in the access bank,
4953 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4955 Added portion of GNU PIC Library under the directory
4956 device/include/pic16 and device/lib/pic16. These files
4957 contain the declarations of SFRs for the PIC18Fxx2 devices.
4958 The directory is initialized via configure from toplevel.
4960 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4962 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4963 the spilllocations to be compared correctly
4965 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4967 * src/SDCCast.c (decorateType): fixed bug introduced today
4969 2004-01-12 Borut Razem <borut.razem AT siol.net>

4987 * doc/sdccman.lyx: Moved and added some sections, small changes
4988 all over. Telling LaTeX to be less strict with word spacing
4989 to better keep the right margin. Changed some notes about
4990 maintainance of the ports in section 3.2.1 - is it OK like this?
4992 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5029 UPPER for immediate operands,
5030 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5032 * src/pic16/peeph.def: all peepholes with movff are commented out,
5033 because there is a problem in the pcode peep optimizer,
5034 * src/pic16/ralloc.c: the register allocator can now reuse local
5035 function symbols for another function. This saves register usage.
5036 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5038 Added file src/pic16/NOTES with information about program writing on
5039 the current port version.

5071 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5074 * src/z80/main.c: added missed needLinkerScript flags (more than
5075 one port structure defined in these file)
5076 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5092 needLinkerScript flag
5094 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5095 * src/pic/glue.c: added variable udata_section_name to
5096 override default uninitialized data segment definition for
5097 devices only with SHAREBANK memory (reported from Erik Epetrich)
5098 * (pic14emitOverlay): modified to emit a commented overlay segment
5099 directive when no overlay data exist
5100 * (picglue): modified to emit uninitialized data segment
5101 according to udata_section_name

5111 2004-01-07 Borut Razem <borut.razem AT siol.net>
5113 * support/scripts/sdcc.nsi: update PATH
5114 * support/scripts/sdcc.ico: craeted
5116 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5127 include information about variables allocated to the overlay
5130 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5132 * as/mcs51/lkmain.c: Help about -Y option

5144 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5146 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5147 (default behaviour).
5149 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5151 A python script to validate compiler diagnostic messages. It can be
5152 used to verify that sdcc complains about bad c source code and
5153 gives a good location of the error.
5154 * support/valdiag/Makefile,
5155 * support/valdiag/valdiag.py,
5156 * support/valdiag/tests/*
5158 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5171 * src/common.h: added ifndef/define/endif macros
5172 around the header file.
5173 Bug reported from Jesus Calvino-Fraga
5175 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5177 * sdcc.spec: updated
5178 * device/include/Makefile.in: don't install CVS directories
5179 * device/lib/Makefile.in: added removal of CVS directories after install
5180 * doc/Makefile: fixed install, added local_icons
5181 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5182 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5183 * src/ds390/gen.c (genRightShift): fixed bug #870788
5184 * src/SDCCast.c (decorateType): fixed bug #870781
5186 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5188 PIC16 port related changes:
5189 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5190 added variable stackPos,
5192 * gen.c: genCall, assignResultValue: added support for
5193 pushing/retrieving function parameters to/from stack,
5194 genFunction,genEndFunction: setup stack frame for the
5196 genAddrOf: will be changed according to bug 863624
5198 * added files genutils.c and genutils.h which contain gen*
5199 debugged and optimised functions extracted from gen.c
5201 * glue.c: added variable 'externs' which holds extern symbols,
5202 pic16emitRegularMap: is modified to properly handle relocatable
5203 symbols under the new scheme,
5204 pic16createInterruptVect: is modified
5205 pic16printPublics: is modified to emit 'global' assembler directives,
5206 added pic16_printExterns to print extern symbols,
5207 pic16glue: initializes stack/frame pointer in the beginning of
5208 the assembly output. Temporary hack, will be corrected later,
5209 because gplink yet does not support stack and SDCC does not
5210 yet support a type of crt0.o object to create the final binary.
5212 * Removed many lines that contain 8051 legacy code.
5213 * The code is finally placed under a 'code' directive.
5214 * Added port specific options.
5216 * _process_pragma: simplified since now we do not need *special*
5217 include file to define SFR registers. But a separate header
5218 will be needed. This will be developed later.
5219 * _pic16_parseOptions: added, parses port specific options:
5220 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5221 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5222 --preplace-udata-with=
5224 * _pic16_setDefaultOptions: modified to initialize section names,
5225 but hack is temporarly out of order since it needs improvement.
5226 * _pic16_genAssemblerPreamble: configuration words are emitted by
5227 their address instead of their name. This part is incomplete and
5228 supports only the 18Fxx2 devices. Other devices will emit an error
5229 during assembly since they do not contain the same set of config
5231 * _pic16_genIVT: is modified,
5233 * pcode.c: added definitions for some hardware registers that are needed
5235 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5236 All PCI entries are updated. Now LFSR is supported.
5237 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5238 * added pic16_newpCodeOpLit2 to support instructions with
5239 two literal arguments
5240 * pic16_pCode2str: corrected code that emits assembler instructions
5241 with two literal operands and those that have an access bit modifier
5242 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5243 this fixes a bug which caused some labels to be lost, when an
5244 assembler directive was added, i.e. banksel,
5245 * pic16_FixRegisterBanking: improved logic that causes the insertion
5247 * InlineFunction: functions that are called once, are not any more
5248 inlined. This can be a port option in the future,
5250 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5252 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5253 hold the corresponding uninitialized symbols,
5254 * pic16_allocProcessorRegister: registers have explicit marked the
5256 * pic16_allocInternalRegister: registers are explicit marked as
5258 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5259 processing list, so bit registers were lost,
5262 * ralloc.h: added field 'accessBank' and original symbol operand
5263 in register definition,
5264 * removed the field isMapped from register definition,
5266 ** Several functions have been removed from various sources:
5267 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5268 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5269 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5270 pic16_assignRelocatableRegisters
5272 ** others have been introduced:
5273 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5274 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5276 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5278 * support/scripts/inc2h.pl: changed definition of BIT_AT
5279 to emit 'sbit at' instead of 'bit at'. This was a request.
5281 PIC16 port related preliminary changes:
5282 * gen.c: prefixed function popRegFromString with
5283 pic16_ and all references to it corrected
5284 * pcode.c: all pic16_pc_* hardware registers prefixed
5285 with underscore (_),
5286 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5287 * ralloc.c: newReg(): when register is REG_SFR then
5288 set address to rIdx,
5289 pic16_allocProcessorRegister(): marks register wasUsed=0
5290 pic16_writeUsedRegs(): added a call to assign processor
5291 registers via pic16_assignFixedRegisters
5293 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5295 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5296 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5297 variables in unused register banks. Also the SSEG is placed
5298 wherever there is enough space for it, and IDATA can be anywhere
5299 in internal RAM. For now compile using -Wl-Y[stack_size].
5300 The mem file is different for this option as well, since it
5301 makes no sense of talking about DSEG lenght.
5303 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5305 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5306 in certain cases, e.g. when ROM assignment, patch provided
5307 from Albert den Haan.
5309 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6352 A few small changes that speed up the peephole optimizer.
6356 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6358 Try to make the peephole optimizer smarter by maintaining
6359 an association between the assembly source code and the
6360 iCodes that originated them. Put this information to use
6361 with a new peephole rule condition "notVolatile" so that
6362 the rules can be aggressive yet still safe.
6367 * src/mcs51/peeph.def
6369 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6373 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6374 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6375 if the left or right operand symbols have the accuse flag set.
6377 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6379 Changed the type of the result of the ! (NOT) operator to char;
6380 previously it returned the same type as the source. This allows
6381 us to eliminate all the genFloatNot functions (all of its target
6382 implementations were very buggy) since !float can use the same
6385 * src/SDCCicode.c (ast2iCode): ! returns char

6394 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6395 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6396 during interrupts. Ensure WSAVE is located at a shared bank address.
6397 2. Fixed page selection in some places
6398 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6399 the registers name strings.
6400 4. Fixed "signed / unsigned compare" compiler warnings.
6401 5. The PIC port manages its own allocation of the general purpose
6402 registers, but makes no attempt to reuse them. As a result when
6403 compiling it soon runs out of general purpose registers. Some
6404 additional code was added to the files pcode.c and device.c to walk
6405 through the function call tree and rename the registers so that they
6415 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6416 genPlus() & genMinus() when the result is the same as left or right

6422 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6424 Made bitfield a distinct type from bit so that bitfields
6425 convert as per ANSI C and bits retain their traditional
6426 boolean style behaviour. Implemented bitfield support in
6434 * src/ds390/gen.c: bit v bitfield split
6435 * src/z80/gen.c: New support for bitfields
6436 * support/regression/tests/bitfields.c: reenabled z80,
6439 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6441 Rules 246.x, 247.x relate to bitfields, the others speed up
6442 access to xdata mapped I/O devices.
6444 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6446 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6448 Cleaned up genPackBits and genUnpackBits and added two helper
6449 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6450 for literal assignments in genPackBits (thanks to Frieder for
6456 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6458 Fixed bug #748310 (pointer to function type mishandled when the
6459 function name is omitted). Also fixed a SIGSEGV when a function
6460 attribute (reentrant, etc) is used on a non-function or on a
6461 function but misplaced before the parameter list.
6463 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6465 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6488 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6490 Made the constant following the "interrupt" keyword optional. If
6491 omitted, the function will not automatically be given an entry
6492 in the interrupt vector table (similar to #pragma NOIV, but
6493 less syntacticly kludgy). The interrupt number is also now
6494 range checked. Also fixed a bug in the high order bit example

6935 condition and ignore commands.
6937 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6939 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
6940 is in parts still quite out of date, I did changes as far as I felt makes sense
6941 for a non-native english speaker.
6942 Please feel free to add to the manual or to correct my changes.
6943 * doc/Makefile: undid touching the date of intermediate tex files.
6945 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6960 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6962 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
6963 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
6964 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
6965 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
6968 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6970 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6971 the regression tests I'm not brave enough to enable 245.b, 245.c
6972 * doc/sdccman.lyx: added latex preamble for hyperref package.
6973 Using pdflatex this will give you a hyperlinked pdf file with
6974 bookmarks. (prepend '%' before /usepackage if this breaks something)
6976 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6990 Applied patch from bug 737905 (renamed yylineo to mylineno):
6997 * src/pic16/pcode.c: Cleaned warnings
6998 * src/pic16/pcodeflow.c: Cleaned warnings
6999 * src/pic16/pcoderegs.c: Cleaned warnings

7010 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7012 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7014 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7015 it can be defined with CFLAGS when running configure
7016 * src/SDCCmain.c: fixed compiling + linking with object files
7018 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7020 * configure.in: configure for pic16 port,
7021 added --disable-pic16-port
7022 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7023 * src/SDCCmain.c: linkOptions is changed to set *,
7024 added if/endif conditional macros to remove options help
7025 messages from optionsTable when a port is not configured, added
7026 support for the PIc16 port in the ports table, when executing
7027 the compiler with no port specified on command line, a default
7028 port is selected with the new macro DEFAULT_PORT which is
7029 defined in port.h, in setDefaultOptions() linkOptions is removed
7030 from initialization assignment, since now it is a set,
7031 parseCmdLine uses setParseWithComma for linkOptions, in
7032 linkEdit() linkOptions are accessed with new function indexSet()
7033 which returns the i'th item of a set variable. See SDCCset.c, in
7034 linkEdit() when calling buildCmdLine(), added linkOptions as
7035 last argument. Now users can pass arguments to gplink via the
7036 -Wl option, main() uses pic16glue() to glue up pic16 programs
7037 * src/SDCCpeeph.c: various changes to support pic16
7038 * src/SDCCset.c: added function void *indexSet(set *, int) to

7044 added macro DEFAULT_PORT
7045 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
7046 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7048 * src/pic16/glue.c: commented out some error producing lines
7049 * src/pic16/main.c: __config directives are commented out to stop
7050 gpasm complaining and test the linkage with gplink, _linkCmd and
7051 _asmCmd changed to be more gplink and gpasm friendly
7052 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7053 produced an error when parsed, peep rule 12 is added to utilize
7054 movff, but it is commented out since the pCode does not support
7055 yet a command with 2 address arguments
7057 2003-05-18 <johan AT balder>
7059 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7060 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7079 on entry now. Add tbreak. Other enhancements and fixes for use
7082 2003-05-12 Borut Razem <borut.razem AT siol.net>
7084 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7086 2003-05-11 Borut Razem <borut.razem AT siol.net>
7088 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7089 the path of bin directory, so that PATH is the only env. variable, which has to be set
7090 in case of standard installation.
7091 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8120 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8122 * in \sdcc\as\mcs51\ changed these files in order to create an
8123 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8124 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8125 following files to include the previous two files: aslink.dsp,
8126 Makefile.aslink, Makefile.bcc, and Makefile.in.
8128 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8129 .adb instead of .cdb
8131 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8133 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8134 value from option --iram-size.
8136 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8138 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8141 2002-09-18 <wiml AT hhhh.org>
8143 * SDCClrange.h: exposed setFromRange() and setToRange()
8144 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8145 packRegsForAccUse() (bug 542397)
8146 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8147 multiple times and emitting the fetch operations more than once
8148 added aopGetUsesAcc() function to allow binary operators to
8149 fetch their operands in the correct order; made genMinus() emit
8150 compact code for X = LITERAL - Y
8152 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8153 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8154 sprintf() in line 1267.
8156 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8157 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8160 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8161 Changes to aslink (All the changes are marked with 'JCF'):
8163 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8166 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8167 area BSEG. Also moves, if possible, the DATA area down into the internal
8168 ram so more space is available.
8170 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8173 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8174 not bytes. Function summary() which creates a memory usage summary
8175 file with extension .mem. Reports of overlaping stack and small stack
8176 size. If the space for the stack is less than 16 bytes aslink trows a
8179 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8180 the 8051. Option 'y' for memory summary output file.
8182 Changes to sdcc (All the changes are marked with 'JCF'):
8184 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8186 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8187 overlaying area for it (uses RegBankUsed[4]).
8189 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8190 bank zero as used by default. By default aslink locates the stack
8191 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8192 the creation of the .mem file. Delegates the allocation of data area
8193 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8194 the begining of the stack area to aslink.
8196 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8197 glue() in SDCCglue.c creates an area for it.
8199 2002-09-03 Borut Razem <borut.razem AT siol.net>
8200 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8201 sdcc/src/pic/glue.c:
8202 introduced atexit() handler for teporay files removal in case of
8203 errors, assertions, ...
8205 2002-08-29 Borut Razem <borut.razem AT siol.net>
8206 * sdcc/support/cpp2/auto-host_vc_in.h:
8207 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8208 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8209 Maybe there is a similar problem with BORLANDC? It should be checked!
8211 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8212 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8213 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8214 was not executed, and the compiler (cl) launched a warning:
8215 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8217 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8218 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

8235 * sdcc/src/yacc.dsp: added
8237 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8238 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8239 and insert the version number definitions from .version
8241 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8243 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8249 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8250 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8252 2002-08-11 Borut Razem <borut.razem AT siol.net>
8253 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8255 2002-08-10 Borut Razem <borut.razem AT siol.net>
8256 * src/SDCCmain.c (main):
8257 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8258 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8259 The consequence was that some temporary files were not removed.
8262 unification of code in functions tempfilename() and tempfile():
8263 function tempnam() is defined in Visual Studio 6.0 and .NET
8265 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8267 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8268 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8269 - removed compiler command line option /WX: Treats all warnings as errors
8270 - update a list of source files, included into the project
8272 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8273 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8274 changed project type to Generic Project so that can be correcly converted to VS.NET project
8276 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8278 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

8282 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8283 added return 0 statements after assert() to make compiler happy
8285 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8286 added newline in the def file to keep MSC compiler satisfied
8288 * sdcc/src/z80/gen.c:
8289 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8290 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8291 - solved MSC error in function aopDump()
8293 * sdcc_vc.h: define PREFIX as "\\sdcc"
8295 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8351 were not getting allocated.
8353 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8356 Fixed left shift. Will promote the left side of a left shift
8357 if a) left shifting more than size of operand or b) when assigned
8358 to something size > size of left side
8360 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8470 * sdcc/src/SDCCloop.c:
8471 Previous fix was not good. basic blocks that have "break" or "return" are
8472 not really partof a loop , but live ranges used in these blocks should
8473 be live thru the entire loop, so set partOfLoop but don't add them to
8476 2002-02-21 <johan AT FRIJA>
