1058 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1060 * device/lib/printf_large.c: removed inline assembly for portability and
1061 readability. Use printf_fast if speed or size are more important.
1062 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1063 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1065 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1067 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1068 prevent compiler warning
1070 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1072 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1073 moved to level 0 and declared as static. Also they are explicit
1074 placed in access bank. This was necessery because some times they
1075 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1076 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1077 optimizations. Currently only compare to unsigned char is implemented,
1078 * src/pic16/gen.c: added fReturnIdx array,
1079 * (struct resolvedIfx) is moved to gen.h and made public,
1080 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1081 * (aopForSym): added an optimization to directly store in stack of
1082 the operand of a SEND iCode,
1083 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1084 but as registers instead (AOP_REG) using the fReturnIdx array,
1085 * (pic16_freeAsmop): remove the freed register from the
1086 _G.sregsAlloc field,
1087 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1088 a compare of 'WREG',
1089 * (pic16_popGetTempRegCond): changed function prototype, now
1090 function takes also a bitVector argument v which holds the current
1091 set of registers that are allocated for stack access by aopForSym,
1092 registers allocated in aopForSym for accessing stack symbols are not
1093 any more part of the functions usedRegs field,
1094 * (genCall): some times aopOp is called for a stack variable to be
1095 send, aopForSym might perform the push, if this is true make sure
1096 that genCall doesn't push the variable twice by testing _G.resDirect,
1097 * (genFunction): changed testing for unspecified interrupt number
1098 from 256 to INTNO_UNSPEC,
1099 * modified selection scheme of frame pointer generation. Previously
1100 if function did use local registers a frame pointer was generated,
1101 now a frame pointer is generated only if function has arguments
1102 (that need PLUSW2 register access), or has stack arguments, or the
1103 compiler is not instructed to omit the frame pointer,
1104 * (genEndFunction): before restoring local registers that were saved
1105 in the function preamble, also restore the registers that *might*
1106 have been allocated for stack access,
1107 * (genRet): removed some old comments,
1108 * (genCmp, the active (RN's) version): added a call to the
1109 pic16_genCmp_special function to perform the compare with a more
1110 robust and optimized way,
1111 * (genInline): a feature has been added in inline code generation,
1112 which allows a wildcard variable substitution when writing inline
1113 assembly. Code is incomplete and experimental therefore undocumented,
1114 * (genCast): changed order of aopOp for result and right to allow
1115 aopForSym to directly load the result if possible,
1116 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1117 perform an optimized compare on some selected special occasions,
1118 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1119 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1120 generate an IVT any more,
1121 * src/pic16/main.c (pic16_optionsTable): added command line option
1123 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1124 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1126 * src/pic16/NOTES: Raphael Neider added in list of active developers
1127 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1128 jumptable_end to prevent bug #,
1129 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1130 inCond and outCond fields,
1131 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1132 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1133 turn off register spilling,
1134 * (packRegsForOneUse): synced with other ports' versions although it
1135 is not used currently,
1136 * (pic16_packRegisters): added an optimization while reading
1137 structure bitfields, some registers may be saved (malloc code is
1138 decreased by 80 bytes)
1140 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1142 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1143 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1144 this can be optimized more?
1146 2005-03-10 Raphael Neider <rneider AT web.de>
1148 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1149 genNearPointerGet): (hopefully) fixed access to bitfields via
1150 pointers (p->bitN = x; and x = p->bitN; failed)

1763 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1765 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
1767 (setFromConditionArgs): friendly operand parser for peephole rules,
1768 (operandBaseName, operandsNotRelated): new peephole condition
1769 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1770 architecture specific register naming into account, handles n-way
1771 comparisons, and supports quoted literals
1772 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
1774 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1782 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1784 Adding support for replacing ljmps with sjmps in jumptables
1785 generated for switch statements. For now you need to set the
1786 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1787 Now 4 algorithms for mcs51 jumptable generation are used:
1788 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1789 addresses loaded pc-relative for up to 112 cases and stack-pushing
1790 target addresses loaded with offset from dptr for up to 256 cases.
1792 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1793 * src/mcs51/main.c: adapted constants for switch table generation
1794 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1817 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1818 to call when a stack overflow occurs,
1819 * (malloc.h): added CVS Id tag,
1820 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1822 * added libc directory. The current version of LibC contains string
1823 functions, ctype functions and macros and some functions of the
1824 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1825 be extensively tested in the future. Standard disclaimer here.
1826 Library is not automatically build yet. But one can build it by
1827 invoking 'make' inside the libc directory.
1828 * added ADC library under libio. Preliminary version yet.
1830 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1837 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1838 * (pic16_storeForReturn): optimized return of 0,
1839 * (genCmp): experimental code for new genCmp which uses PIC18's
1840 special compare&skip instructions. Initial tests fail some times
1841 with variables grater than 1 byte in size, so new code is disabled,
1842 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1844 * (genCast): began a fix to optimize the casting of a bit to another
1845 bit, now assigning a bitfield to another bitfield will fail, sorry,
1846 * src/pic16/main.c: disabled the use of lr-support feature,
1847 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1848 * added some function prototypes, added function _debugf prototype,

1850 bits with offset (case PO_GPR_BIT),
1851 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1853 * (isBankInstruction): modified to return 0 for no banking instruction,
1854 and 1 for banking instruction,
1855 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1856 caused stop processing pCodes after a inline assembly block,
1857 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1858 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1859 registers when it shouldn't,
1860 * src/pic16/ralloc.c (allocReg): add preliminary support for
1861 supporting a limited set of temporary registers,
1863 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1865 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1866 genDataPointerSet): ensure assignments always copy in MSB to LSB
1868 (loadRegFromAop): recognize CLRH optimization,
1869 (genFunction): optimize RECEIVE iCodes in reentrant functions
1871 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1873 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1874 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1876 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
1877 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
1878 contiguous with data
1880 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1882 * device/lib/_gptrget.c (_gptrget),
1883 * device/lib/_gptrgetc.c (_gptrgetc),
1884 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1885 instead of sjmp to ret
1886 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1887 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1889 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4861 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
4863 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
4865 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
4868 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4870 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4871 loaded with the linker search paths (-L arguments) and the libraries
4872 to be linked with the current source (-l arguments). Changes
4873 currently will affect only the pic16 port.
4874 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4875 include path the port specific paths and port specific libraries,
4876 * gplink command now contains the $3 argument,
4877 * src/pic16/device.h,
4878 * src/pic16/device.c,: structure PIC_device is made public and
4879 renamed to PIC16_device, the same for variable Pics which is renamed
4880 to Pics16. Updated all references to them.
4881 * src/pic16/glue.c (pic16glue): corrected bug with code
4882 initialization which bypassed the variable initializations block.
4884 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4885 COMPILE_FLAGS and added the --nostdinc option
4887 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4889 * device/include/mc68hc908jb8.h: Register defs for another member
4890 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4892 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4894 Documenting changes from previous commits.
4895 * configure.in (version 1.56),
4896 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4897 when generating output files to configure the pic16 library,
4898 but now I've commented it out, since gputils aren't installed in the
4899 SF compile farm, so library won't compile
4901 * device/lib/Makefile.in (version 1.56): initially I've added in
4902 target 'all' the prerequestive 'model-pic16' so it compiled the
4903 pic16 library, but now I've commented it out for the same reasons
4905 * added targets 'model-pic16' and 'objects-pic16' to compile the
4907 * added target 'port-specific-objects-pic16' to handle the
4908 generated libraries and copy them into the build/ directory
4909 * added target 'clean-intermediate-pic16' to clean intermediate
4910 files into pic16 directory
4911 * in target 'installdirs' added line to create directory pic16 in
4912 the installation path
4914 * device/include/Makefile.in (version 1.11): in target 'install'
4915 added lines to copy all header files to installation path,
4916 * in target 'installdirs' added line create directory for pic16
4917 headers in the installation path
4919 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4932 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4933 option so that it actually works. Made it specific to the z80, since
4934 the gbz80 doesn't have these kinds of I/O ports.
4936 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4938 * device/include/z180.h,

4951 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4953 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4954 changed interrupt vector table generation to only emit declared vectors.
4955 * device/include/Makefile.in: added missing backslash
4956 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4958 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4960 Mainly changes to support compilation of the device libraries
4961 * src/pic16/device.c: stack is allocated via symbol and not
4962 via literal number. The symbol is placed in the corresponding
4963 position of the data ram
4964 * (pic16_dump_section): relocatable and absolute uninitialized
4965 data are now emitted in sorted order to reduce section naming,
4966 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4967 weren't marked as being in the access bank,
4969 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4971 Added portion of GNU PIC Library under the directory
4972 device/include/pic16 and device/lib/pic16. These files
4973 contain the declarations of SFRs for the PIC18Fxx2 devices.
4974 The directory is initialized via configure from toplevel.
4976 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4978 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4979 the spilllocations to be compared correctly
4981 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4983 * src/SDCCast.c (decorateType): fixed bug introduced today
4985 2004-01-12 Borut Razem <borut.razem AT siol.net>
4987 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4990 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4992 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4993 in simpler and even better code
4995 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4997 * src/SDCCicode.c (operandOperation): fixed bug #874819

5001 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5003 * doc/sdccman.lyx: Moved and added some sections, small changes
5004 all over. Telling LaTeX to be less strict with word spacing
5005 to better keep the right margin. Changed some notes about
5006 maintainance of the ports in section 3.2.1 - is it OK like this?
5008 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5010 SDCC source changes:
5011 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5044 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5045 UPPER for immediate operands,
5046 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5048 * src/pic16/peeph.def: all peepholes with movff are commented out,
5049 because there is a problem in the pcode peep optimizer,
5050 * src/pic16/ralloc.c: the register allocator can now reuse local
5051 function symbols for another function. This saves register usage.
5052 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5054 Added file src/pic16/NOTES with information about program writing on
5055 the current port version.

5064 * src/SDCCmain.c : fixed #872250: -l command line defined library
5065 files are scanned before standard library files
5067 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5084 gen51Code): more efficient parameter receive for --model-large
5087 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5090 * src/z80/main.c: added missed needLinkerScript flags (more than
5091 one port structure defined in these file)
5092 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5107 * src/z80/main.c: changed appropriately to configure
5108 needLinkerScript flag
5110 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5111 * src/pic/glue.c: added variable udata_section_name to
5112 override default uninitialized data segment definition for
5113 devices only with SHAREBANK memory (reported from Erik Epetrich)
5114 * (pic14emitOverlay): modified to emit a commented overlay segment
5115 directive when no overlay data exist
5116 * (picglue): modified to emit uninitialized data segment
5117 according to udata_section_name

5122 arguments via -W option
5123 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5124 object file from '.rel' to '.o' in port->linker structure,
5125 changed size of fptr from 2 to 3 in port structure
5127 2004-01-07 Borut Razem <borut.razem AT siol.net>
5129 * support/scripts/sdcc.nsi: update PATH
5130 * support/scripts/sdcc.ico: craeted
5132 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
5134 * device/include/Makefile.in: fix install
5135 * doc/Makefile: fix install
5137 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5139 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5141 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
5142 how the function variable allocation summary is displayed; also
5143 include information about variables allocated to the overlay
5146 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5148 * as/mcs51/lkmain.c: Help about -Y option

5158 LEFT_OP (left shift)
5160 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5162 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5163 (default behaviour).
5165 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5167 A python script to validate compiler diagnostic messages. It can be
5168 used to verify that sdcc complains about bad c source code and
5169 gives a good location of the error.
5170 * support/valdiag/Makefile,
5171 * support/valdiag/valdiag.py,
5172 * support/valdiag/tests/*
5174 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5176 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
5177 * src/SDCCsymt.c (newEnumType),

5185 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5187 * src/common.h: added ifndef/define/endif macros
5188 around the header file.
5189 Bug reported from Jesus Calvino-Fraga
5191 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5193 * sdcc.spec: updated
5194 * device/include/Makefile.in: don't install CVS directories
5195 * device/lib/Makefile.in: added removal of CVS directories after install
5196 * doc/Makefile: fixed install, added local_icons
5197 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5198 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5199 * src/ds390/gen.c (genRightShift): fixed bug #870788
5200 * src/SDCCast.c (decorateType): fixed bug #870781
5202 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5204 PIC16 port related changes:
5205 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5206 added variable stackPos,
5208 * gen.c: genCall, assignResultValue: added support for
5209 pushing/retrieving function parameters to/from stack,
5210 genFunction,genEndFunction: setup stack frame for the
5212 genAddrOf: will be changed according to bug 863624
5214 * added files genutils.c and genutils.h which contain gen*
5215 debugged and optimised functions extracted from gen.c
5217 * glue.c: added variable 'externs' which holds extern symbols,
5218 pic16emitRegularMap: is modified to properly handle relocatable
5219 symbols under the new scheme,
5220 pic16createInterruptVect: is modified
5221 pic16printPublics: is modified to emit 'global' assembler directives,
5222 added pic16_printExterns to print extern symbols,
5223 pic16glue: initializes stack/frame pointer in the beginning of
5224 the assembly output. Temporary hack, will be corrected later,
5225 because gplink yet does not support stack and SDCC does not
5226 yet support a type of crt0.o object to create the final binary.
5228 * Removed many lines that contain 8051 legacy code.
5229 * The code is finally placed under a 'code' directive.
5230 * Added port specific options.
5232 * _process_pragma: simplified since now we do not need *special*
5233 include file to define SFR registers. But a separate header
5234 will be needed. This will be developed later.
5235 * _pic16_parseOptions: added, parses port specific options:
5236 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5237 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5238 --preplace-udata-with=
5240 * _pic16_setDefaultOptions: modified to initialize section names,
5241 but hack is temporarly out of order since it needs improvement.
5242 * _pic16_genAssemblerPreamble: configuration words are emitted by
5243 their address instead of their name. This part is incomplete and
5244 supports only the 18Fxx2 devices. Other devices will emit an error
5245 during assembly since they do not contain the same set of config
5247 * _pic16_genIVT: is modified,
5249 * pcode.c: added definitions for some hardware registers that are needed
5251 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5252 All PCI entries are updated. Now LFSR is supported.
5253 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5254 * added pic16_newpCodeOpLit2 to support instructions with
5255 two literal arguments
5256 * pic16_pCode2str: corrected code that emits assembler instructions
5257 with two literal operands and those that have an access bit modifier
5258 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5259 this fixes a bug which caused some labels to be lost, when an
5260 assembler directive was added, i.e. banksel,
5261 * pic16_FixRegisterBanking: improved logic that causes the insertion
5263 * InlineFunction: functions that are called once, are not any more
5264 inlined. This can be a port option in the future,
5266 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5268 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5269 hold the corresponding uninitialized symbols,
5270 * pic16_allocProcessorRegister: registers have explicit marked the
5272 * pic16_allocInternalRegister: registers are explicit marked as
5274 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5275 processing list, so bit registers were lost,
5278 * ralloc.h: added field 'accessBank' and original symbol operand
5279 in register definition,
5280 * removed the field isMapped from register definition,
5282 ** Several functions have been removed from various sources:
5283 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5284 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5285 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5286 pic16_assignRelocatableRegisters
5288 ** others have been introduced:
5289 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5290 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5292 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5294 * support/scripts/inc2h.pl: changed definition of BIT_AT
5295 to emit 'sbit at' instead of 'bit at'. This was a request.
5297 PIC16 port related preliminary changes:
5298 * gen.c: prefixed function popRegFromString with
5299 pic16_ and all references to it corrected
5300 * pcode.c: all pic16_pc_* hardware registers prefixed
5301 with underscore (_),
5302 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5303 * ralloc.c: newReg(): when register is REG_SFR then
5304 set address to rIdx,
5305 pic16_allocProcessorRegister(): marks register wasUsed=0
5306 pic16_writeUsedRegs(): added a call to assign processor
5307 registers via pic16_assignFixedRegisters
5309 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5311 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5312 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5313 variables in unused register banks. Also the SSEG is placed
5314 wherever there is enough space for it, and IDATA can be anywhere
5315 in internal RAM. For now compile using -Wl-Y[stack_size].
5316 The mem file is different for this option as well, since it
5317 makes no sense of talking about DSEG lenght.
5319 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5321 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5322 in certain cases, e.g. when ROM assignment, patch provided
5323 from Albert den Haan.
5325 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6343 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6344 these ports have their own __sdcc_external_start()
6346 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6348 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6349 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6350 type for bits was changed. It resulted in bit variables becoming
6351 global, which is not permitted in PIC 14 assembly output.
6353 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6355 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6357 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6359 Z80 and MCS51 linkers complaint if a public symbol is defined
6360 in more than one library module:

6368 A few small changes that speed up the peephole optimizer.
6372 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6374 Try to make the peephole optimizer smarter by maintaining
6375 an association between the assembly source code and the
6376 iCodes that originated them. Put this information to use
6377 with a new peephole rule condition "notVolatile" so that
6378 the rules can be aggressive yet still safe.
6383 * src/mcs51/peeph.def
6385 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6389 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6390 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6391 if the left or right operand symbols have the accuse flag set.
6393 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6395 Changed the type of the result of the ! (NOT) operator to char;
6396 previously it returned the same type as the source. This allows
6397 us to eliminate all the genFloatNot functions (all of its target
6398 implementations were very buggy) since !float can use the same
6401 * src/SDCCicode.c (ast2iCode): ! returns char

6403 * src/ds390/gen.c (genNot, genNotFloat),
6404 * src/z80/gen.c (genNot, genNotFloat),
6405 * src/pic/gen.c (genNot, genNotFloat),

6410 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6411 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6412 during interrupts. Ensure WSAVE is located at a shared bank address.
6413 2. Fixed page selection in some places
6414 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6415 the registers name strings.
6416 4. Fixed "signed / unsigned compare" compiler warnings.
6417 5. The PIC port manages its own allocation of the general purpose
6418 registers, but makes no attempt to reuse them. As a result when
6419 compiling it soon runs out of general purpose registers. Some
6420 additional code was added to the files pcode.c and device.c to walk
6421 through the function call tree and rename the registers so that they
6431 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6432 genPlus() & genMinus() when the result is the same as left or right

6438 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6440 Made bitfield a distinct type from bit so that bitfields
6441 convert as per ANSI C and bits retain their traditional
6442 boolean style behaviour. Implemented bitfield support in
6450 * src/ds390/gen.c: bit v bitfield split
6451 * src/z80/gen.c: New support for bitfields
6452 * support/regression/tests/bitfields.c: reenabled z80,
6455 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6457 Rules 246.x, 247.x relate to bitfields, the others speed up
6458 access to xdata mapped I/O devices.
6460 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6462 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6464 Cleaned up genPackBits and genUnpackBits and added two helper
6465 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6466 for literal assignments in genPackBits (thanks to Frieder for
6472 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6474 Fixed bug #748310 (pointer to function type mishandled when the
6475 function name is omitted). Also fixed a SIGSEGV when a function
6476 attribute (reentrant, etc) is used on a non-function or on a
6477 function but misplaced before the parameter list.
6479 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6481 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6482 * support/Util/SDCCerr.h,
6483 * support/Util/SDCCerr.c: Added func attr misuse error msg

6504 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6506 Made the constant following the "interrupt" keyword optional. If
6507 omitted, the function will not automatically be given an entry
6508 in the interrupt vector table (similar to #pragma NOIV, but
6509 less syntacticly kludgy). The interrupt number is also now
6510 range checked. Also fixed a bug in the high order bit example
6517 * support/Util/SDCCerr.c
6518 * support/Util/SDCCerr.h

6524 * src/SDCCicode.c (operandOperation): rewritten some ops
6525 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6526 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6528 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6529 be re-activated by defining REDUCE_LITERALS)
6530 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6531 unsigned, but are signed by default
6532 * src/SDCCval.c (constVal): rearranged
6533 * src/SDCCval.c (valMod): preliminary fix
6534 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6986 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6987 the regression tests I'm not brave enough to enable 245.b, 245.c
6988 * doc/sdccman.lyx: added latex preamble for hyperref package.
6989 Using pdflatex this will give you a hyperlinked pdf file with
6990 bookmarks. (prepend '%' before /usepackage if this breaks something)

7028 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7030 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7031 it can be defined with CFLAGS when running configure
7032 * src/SDCCmain.c: fixed compiling + linking with object files
7034 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7037 added --disable-pic16-port
7038 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7039 * src/SDCCmain.c: linkOptions is changed to set *,
7040 added if/endif conditional macros to remove options help
7041 messages from optionsTable when a port is not configured, added
7042 support for the PIc16 port in the ports table, when executing
7043 the compiler with no port specified on command line, a default
7044 port is selected with the new macro DEFAULT_PORT which is
7045 defined in port.h, in setDefaultOptions() linkOptions is removed
7046 from initialization assignment, since now it is a set,
7047 parseCmdLine uses setParseWithComma for linkOptions, in
7048 linkEdit() linkOptions are accessed with new function indexSet()
7049 which returns the i'th item of a set variable. See SDCCset.c, in
7050 linkEdit() when calling buildCmdLine(), added linkOptions as
7051 last argument. Now users can pass arguments to gplink via the
7052 -Wl option, main() uses pic16glue() to glue up pic16 programs

7064 * src/pic16/glue.c: commented out some error producing lines
7065 * src/pic16/main.c: __config directives are commented out to stop
7066 gpasm complaining and test the linkage with gplink, _linkCmd and
7067 _asmCmd changed to be more gplink and gpasm friendly
7068 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7069 produced an error when parsed, peep rule 12 is added to utilize
7070 movff, but it is commented out since the pCode does not support
7071 yet a command with 2 address arguments
7073 2003-05-18 <johan AT balder>
7075 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7076 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7100 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7102 2003-05-11 Borut Razem <borut.razem AT siol.net>
7104 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7105 the path of bin directory, so that PATH is the only env. variable, which has to be set
7106 in case of standard installation.
7107 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8136 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8138 * in \sdcc\as\mcs51\ changed these files in order to create an
8139 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8140 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8141 following files to include the previous two files: aslink.dsp,
8142 Makefile.aslink, Makefile.bcc, and Makefile.in.
8144 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8145 .adb instead of .cdb
8147 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8149 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8150 value from option --iram-size.
8152 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8154 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8157 2002-09-18 <wiml AT hhhh.org>
8159 * SDCClrange.h: exposed setFromRange() and setToRange()
8160 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8161 packRegsForAccUse() (bug 542397)
8162 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8163 multiple times and emitting the fetch operations more than once
8164 added aopGetUsesAcc() function to allow binary operators to
8165 fetch their operands in the correct order; made genMinus() emit
8166 compact code for X = LITERAL - Y
8168 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8169 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8170 sprintf() in line 1267.
8172 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8173 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8176 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8177 Changes to aslink (All the changes are marked with 'JCF'):
8179 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8182 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8183 area BSEG. Also moves, if possible, the DATA area down into the internal
8184 ram so more space is available.
8186 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8189 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8190 not bytes. Function summary() which creates a memory usage summary
8191 file with extension .mem. Reports of overlaping stack and small stack
8192 size. If the space for the stack is less than 16 bytes aslink trows a
8195 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8196 the 8051. Option 'y' for memory summary output file.
8198 Changes to sdcc (All the changes are marked with 'JCF'):
8200 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8202 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8203 overlaying area for it (uses RegBankUsed[4]).
8205 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8206 bank zero as used by default. By default aslink locates the stack
8207 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8208 the creation of the .mem file. Delegates the allocation of data area
8209 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8210 the begining of the stack area to aslink.
8212 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8213 glue() in SDCCglue.c creates an area for it.
8215 2002-09-03 Borut Razem <borut.razem AT siol.net>
8216 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8217 sdcc/src/pic/glue.c:
8218 introduced atexit() handler for teporay files removal in case of
8219 errors, assertions, ...
8221 2002-08-29 Borut Razem <borut.razem AT siol.net>
8222 * sdcc/support/cpp2/auto-host_vc_in.h:
8223 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8224 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8225 Maybe there is a similar problem with BORLANDC? It should be checked!
8227 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8228 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8229 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8230 was not executed, and the compiler (cl) launched a warning:
8231 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8233 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8234 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

8246 - added Release configuration in VS projects
8247 - review of compiler an linker options
8248 - VC .exe files are generated in bin_vc directory, not to interfere
8249 with binaries generated from other projects (cygwin, mingw, bcc ...)
8251 * sdcc/src/yacc.dsp: added
8253 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8254 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8255 and insert the version number definitions from .version

8266 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8268 2002-08-11 Borut Razem <borut.razem AT siol.net>
8269 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8271 2002-08-10 Borut Razem <borut.razem AT siol.net>
8272 * src/SDCCmain.c (main):
8273 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8274 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8275 The consequence was that some temporary files were not removed.
8278 unification of code in functions tempfilename() and tempfile():
8279 function tempnam() is defined in Visual Studio 6.0 and .NET
8281 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8283 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8284 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8285 - removed compiler command line option /WX: Treats all warnings as errors
8286 - update a list of source files, included into the project
8288 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8289 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8290 changed project type to Generic Project so that can be correcly converted to VS.NET project
8292 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8294 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

8298 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8299 added return 0 statements after assert() to make compiler happy
8301 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8302 added newline in the def file to keep MSC compiler satisfied
8304 * sdcc/src/z80/gen.c:
8305 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8306 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8307 - solved MSC error in function aopDump()
8309 * sdcc_vc.h: define PREFIX as "\\sdcc"
8311 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8367 were not getting allocated.
8369 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8372 Fixed left shift. Will promote the left side of a left shift
8373 if a) left shifting more than size of operand or b) when assigned
8374 to something size > size of left side
8376 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8486 * sdcc/src/SDCCloop.c:
8487 Previous fix was not good. basic blocks that have "break" or "return" are
8488 not really partof a loop , but live ranges used in these blocks should
8489 be live thru the entire loop, so set partOfLoop but don't add them to
8492 2002-02-21 <johan AT FRIJA>

9336 2001-09-02 Michael Hope <michaelh AT juju.net.nz>
9338 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
9340 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
9342 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
9344 * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs. Had to shift some functions about to do it.

9348 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
9349 (genCmp): Fixed up genCmp for the GB with longs.
9351 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
9353 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
9355 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
9357 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

9361 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
9363 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
9365 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
9367 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
9369 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
9371 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
9373 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
