1064 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1066 * device/lib/printf_large.c: removed inline assembly for portability and
1067 readability. Use printf_fast if speed or size are more important.
1068 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1069 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1071 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1073 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1074 prevent compiler warning
1076 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1078 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1079 moved to level 0 and declared as static. Also they are explicit
1080 placed in access bank. This was necessery because some times they
1081 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1082 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1083 optimizations. Currently only compare to unsigned char is implemented,
1084 * src/pic16/gen.c: added fReturnIdx array,
1085 * (struct resolvedIfx) is moved to gen.h and made public,
1086 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1087 * (aopForSym): added an optimization to directly store in stack of
1088 the operand of a SEND iCode,
1089 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1090 but as registers instead (AOP_REG) using the fReturnIdx array,
1091 * (pic16_freeAsmop): remove the freed register from the
1092 _G.sregsAlloc field,
1093 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1094 a compare of 'WREG',
1095 * (pic16_popGetTempRegCond): changed function prototype, now
1096 function takes also a bitVector argument v which holds the current
1097 set of registers that are allocated for stack access by aopForSym,
1098 registers allocated in aopForSym for accessing stack symbols are not
1099 any more part of the functions usedRegs field,
1100 * (genCall): some times aopOp is called for a stack variable to be
1101 send, aopForSym might perform the push, if this is true make sure
1102 that genCall doesn't push the variable twice by testing _G.resDirect,
1103 * (genFunction): changed testing for unspecified interrupt number
1104 from 256 to INTNO_UNSPEC,
1105 * modified selection scheme of frame pointer generation. Previously
1106 if function did use local registers a frame pointer was generated,
1107 now a frame pointer is generated only if function has arguments
1108 (that need PLUSW2 register access), or has stack arguments, or the
1109 compiler is not instructed to omit the frame pointer,
1110 * (genEndFunction): before restoring local registers that were saved
1111 in the function preamble, also restore the registers that *might*
1112 have been allocated for stack access,
1113 * (genRet): removed some old comments,
1114 * (genCmp, the active (RN's) version): added a call to the
1115 pic16_genCmp_special function to perform the compare with a more
1116 robust and optimized way,
1117 * (genInline): a feature has been added in inline code generation,
1118 which allows a wildcard variable substitution when writing inline
1119 assembly. Code is incomplete and experimental therefore undocumented,
1120 * (genCast): changed order of aopOp for result and right to allow
1121 aopForSym to directly load the result if possible,
1122 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1123 perform an optimized compare on some selected special occasions,
1124 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1125 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1126 generate an IVT any more,
1127 * src/pic16/main.c (pic16_optionsTable): added command line option
1129 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1130 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1132 * src/pic16/NOTES: Raphael Neider added in list of active developers
1133 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1134 jumptable_end to prevent bug #,
1135 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1136 inCond and outCond fields,
1137 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1138 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1139 turn off register spilling,
1140 * (packRegsForOneUse): synced with other ports' versions although it
1141 is not used currently,
1142 * (pic16_packRegisters): added an optimization while reading
1143 structure bitfields, some registers may be saved (malloc code is
1144 decreased by 80 bytes)
1146 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1148 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1149 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1150 this can be optimized more?
1152 2005-03-10 Raphael Neider <rneider AT web.de>
1154 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1155 genNearPointerGet): (hopefully) fixed access to bitfields via
1156 pointers (p->bitN = x; and x = p->bitN; failed)

1771 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
1773 (setFromConditionArgs): friendly operand parser for peephole rules,
1774 (operandBaseName, operandsNotRelated): new peephole condition
1775 "operandsNotRelated" -- similar to "operandsNotSame", but takes
1776 architecture specific register naming into account, handles n-way
1777 comparisons, and supports quoted literals
1778 * src/mcs51/peeph.def: restored rule 177.d with an extra condition

1788 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1790 Adding support for replacing ljmps with sjmps in jumptables
1791 generated for switch statements. For now you need to set the
1792 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1793 Now 4 algorithms for mcs51 jumptable generation are used:
1794 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1795 addresses loaded pc-relative for up to 112 cases and stack-pushing
1796 target addresses loaded with offset from dptr for up to 256 cases.
1798 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1799 * src/mcs51/main.c: adapted constants for switch table generation
1800 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1823 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1824 to call when a stack overflow occurs,
1825 * (malloc.h): added CVS Id tag,
1826 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1828 * added libc directory. The current version of LibC contains string
1829 functions, ctype functions and macros and some functions of the
1830 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1831 be extensively tested in the future. Standard disclaimer here.
1832 Library is not automatically build yet. But one can build it by
1833 invoking 'make' inside the libc directory.
1834 * added ADC library under libio. Preliminary version yet.
1836 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1843 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1844 * (pic16_storeForReturn): optimized return of 0,
1845 * (genCmp): experimental code for new genCmp which uses PIC18's
1846 special compare&skip instructions. Initial tests fail some times
1847 with variables grater than 1 byte in size, so new code is disabled,
1848 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1850 * (genCast): began a fix to optimize the casting of a bit to another
1851 bit, now assigning a bitfield to another bitfield will fail, sorry,
1852 * src/pic16/main.c: disabled the use of lr-support feature,
1853 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1854 * added some function prototypes, added function _debugf prototype,

1856 bits with offset (case PO_GPR_BIT),
1857 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1859 * (isBankInstruction): modified to return 0 for no banking instruction,
1860 and 1 for banking instruction,
1861 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1862 caused stop processing pCodes after a inline assembly block,
1863 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1864 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1865 registers when it shouldn't,
1866 * src/pic16/ralloc.c (allocReg): add preliminary support for
1867 supporting a limited set of temporary registers,
1869 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1871 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1872 genDataPointerSet): ensure assignments always copy in MSB to LSB
1874 (loadRegFromAop): recognize CLRH optimization,
1875 (genFunction): optimize RECEIVE iCodes in reentrant functions
1877 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1879 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1880 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1882 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
1883 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
1884 contiguous with data

1891 instead of sjmp to ret
1892 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1893 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1895 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4874 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4876 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4877 loaded with the linker search paths (-L arguments) and the libraries
4878 to be linked with the current source (-l arguments). Changes
4879 currently will affect only the pic16 port.
4880 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4881 include path the port specific paths and port specific libraries,
4882 * gplink command now contains the $3 argument,
4883 * src/pic16/device.h,
4884 * src/pic16/device.c,: structure PIC_device is made public and
4885 renamed to PIC16_device, the same for variable Pics which is renamed
4886 to Pics16. Updated all references to them.
4887 * src/pic16/glue.c (pic16glue): corrected bug with code
4888 initialization which bypassed the variable initializations block.
4890 * device/lib/pic16/Makefile.rules: removed --penable-stack from

4898 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4900 Documenting changes from previous commits.
4901 * configure.in (version 1.56),
4902 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4903 when generating output files to configure the pic16 library,
4904 but now I've commented it out, since gputils aren't installed in the
4905 SF compile farm, so library won't compile
4907 * device/lib/Makefile.in (version 1.56): initially I've added in
4908 target 'all' the prerequestive 'model-pic16' so it compiled the
4909 pic16 library, but now I've commented it out for the same reasons
4911 * added targets 'model-pic16' and 'objects-pic16' to compile the
4913 * added target 'port-specific-objects-pic16' to handle the
4914 generated libraries and copy them into the build/ directory
4915 * added target 'clean-intermediate-pic16' to clean intermediate
4916 files into pic16 directory
4917 * in target 'installdirs' added line to create directory pic16 in
4918 the installation path
4920 * device/include/Makefile.in (version 1.11): in target 'install'
4921 added lines to copy all header files to installation path,
4922 * in target 'installdirs' added line create directory for pic16
4923 headers in the installation path
4925 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4936 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4938 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4939 option so that it actually works. Made it specific to the z80, since
4940 the gbz80 doesn't have these kinds of I/O ports.
4942 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4944 * device/include/z180.h,

4951 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
4952 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4953 portmode; added deprecation warning for bank= and protmode= forms.
4954 Also, guard against buffer overflow.
4955 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4957 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4959 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4960 changed interrupt vector table generation to only emit declared vectors.
4961 * device/include/Makefile.in: added missing backslash
4962 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4964 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4966 Mainly changes to support compilation of the device libraries
4967 * src/pic16/device.c: stack is allocated via symbol and not
4968 via literal number. The symbol is placed in the corresponding
4969 position of the data ram
4970 * (pic16_dump_section): relocatable and absolute uninitialized
4971 data are now emitted in sorted order to reduce section naming,
4972 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4973 weren't marked as being in the access bank,
4975 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4977 Added portion of GNU PIC Library under the directory
4978 device/include/pic16 and device/lib/pic16. These files
4979 contain the declarations of SFRs for the PIC18Fxx2 devices.
4980 The directory is initialized via configure from toplevel.
4982 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4984 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4985 the spilllocations to be compared correctly
4987 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4989 * src/SDCCast.c (decorateType): fixed bug introduced today
4991 2004-01-12 Borut Razem <borut.razem AT siol.net>
4993 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4996 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4998 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4999 in simpler and even better code
5001 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5003 * src/SDCCicode.c (operandOperation): fixed bug #874819

5007 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5009 * doc/sdccman.lyx: Moved and added some sections, small changes
5010 all over. Telling LaTeX to be less strict with word spacing
5011 to better keep the right margin. Changed some notes about
5012 maintainance of the ports in section 3.2.1 - is it OK like this?
5014 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5016 SDCC source changes:
5017 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5050 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5051 UPPER for immediate operands,
5052 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5054 * src/pic16/peeph.def: all peepholes with movff are commented out,
5055 because there is a problem in the pcode peep optimizer,
5056 * src/pic16/ralloc.c: the register allocator can now reuse local
5057 function symbols for another function. This saves register usage.
5058 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5060 Added file src/pic16/NOTES with information about program writing on
5061 the current port version.

5070 * src/SDCCmain.c : fixed #872250: -l command line defined library
5071 files are scanned before standard library files
5073 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5093 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5096 * src/z80/main.c: added missed needLinkerScript flags (more than
5097 one port structure defined in these file)
5098 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5114 needLinkerScript flag
5116 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5117 * src/pic/glue.c: added variable udata_section_name to
5118 override default uninitialized data segment definition for
5119 devices only with SHAREBANK memory (reported from Erik Epetrich)
5120 * (pic14emitOverlay): modified to emit a commented overlay segment
5121 directive when no overlay data exist
5122 * (picglue): modified to emit uninitialized data segment
5123 according to udata_section_name

5129 * src/pic16/main.c: added $l in _asmCmd, changed extension for
5130 object file from '.rel' to '.o' in port->linker structure,
5131 changed size of fptr from 2 to 3 in port structure
5133 2004-01-07 Borut Razem <borut.razem AT siol.net>
5135 * support/scripts/sdcc.nsi: update PATH
5136 * support/scripts/sdcc.ico: craeted
5138 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

5141 * doc/Makefile: fix install
5143 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5145 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
5147 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

5149 include information about variables allocated to the overlay
5152 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5154 * as/mcs51/lkmain.c: Help about -Y option

5166 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5168 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5169 (default behaviour).
5171 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5173 A python script to validate compiler diagnostic messages. It can be
5174 used to verify that sdcc complains about bad c source code and
5175 gives a good location of the error.
5176 * support/valdiag/Makefile,
5177 * support/valdiag/valdiag.py,
5178 * support/valdiag/tests/*
5180 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5182 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5195 Bug reported from Jesus Calvino-Fraga
5197 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5199 * sdcc.spec: updated
5200 * device/include/Makefile.in: don't install CVS directories
5201 * device/lib/Makefile.in: added removal of CVS directories after install
5202 * doc/Makefile: fixed install, added local_icons
5203 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5204 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5205 * src/ds390/gen.c (genRightShift): fixed bug #870788
5206 * src/SDCCast.c (decorateType): fixed bug #870781
5208 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5210 PIC16 port related changes:
5211 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5212 added variable stackPos,
5214 * gen.c: genCall, assignResultValue: added support for
5215 pushing/retrieving function parameters to/from stack,
5216 genFunction,genEndFunction: setup stack frame for the
5218 genAddrOf: will be changed according to bug 863624
5220 * added files genutils.c and genutils.h which contain gen*
5221 debugged and optimised functions extracted from gen.c
5223 * glue.c: added variable 'externs' which holds extern symbols,
5224 pic16emitRegularMap: is modified to properly handle relocatable
5225 symbols under the new scheme,
5226 pic16createInterruptVect: is modified
5227 pic16printPublics: is modified to emit 'global' assembler directives,
5228 added pic16_printExterns to print extern symbols,
5229 pic16glue: initializes stack/frame pointer in the beginning of
5230 the assembly output. Temporary hack, will be corrected later,
5231 because gplink yet does not support stack and SDCC does not
5232 yet support a type of crt0.o object to create the final binary.
5234 * Removed many lines that contain 8051 legacy code.
5235 * The code is finally placed under a 'code' directive.
5236 * Added port specific options.
5238 * _process_pragma: simplified since now we do not need *special*
5239 include file to define SFR registers. But a separate header
5240 will be needed. This will be developed later.
5241 * _pic16_parseOptions: added, parses port specific options:
5242 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5243 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5244 --preplace-udata-with=
5246 * _pic16_setDefaultOptions: modified to initialize section names,
5247 but hack is temporarly out of order since it needs improvement.
5248 * _pic16_genAssemblerPreamble: configuration words are emitted by
5249 their address instead of their name. This part is incomplete and
5250 supports only the 18Fxx2 devices. Other devices will emit an error
5251 during assembly since they do not contain the same set of config
5253 * _pic16_genIVT: is modified,
5255 * pcode.c: added definitions for some hardware registers that are needed
5257 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5258 All PCI entries are updated. Now LFSR is supported.
5259 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5260 * added pic16_newpCodeOpLit2 to support instructions with
5261 two literal arguments
5262 * pic16_pCode2str: corrected code that emits assembler instructions
5263 with two literal operands and those that have an access bit modifier
5264 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5265 this fixes a bug which caused some labels to be lost, when an
5266 assembler directive was added, i.e. banksel,
5267 * pic16_FixRegisterBanking: improved logic that causes the insertion
5269 * InlineFunction: functions that are called once, are not any more
5270 inlined. This can be a port option in the future,
5272 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5274 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5275 hold the corresponding uninitialized symbols,
5276 * pic16_allocProcessorRegister: registers have explicit marked the
5278 * pic16_allocInternalRegister: registers are explicit marked as
5280 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5281 processing list, so bit registers were lost,
5284 * ralloc.h: added field 'accessBank' and original symbol operand
5285 in register definition,
5286 * removed the field isMapped from register definition,
5288 ** Several functions have been removed from various sources:
5289 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5290 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5291 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5292 pic16_assignRelocatableRegisters
5294 ** others have been introduced:
5295 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5296 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5298 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5300 * support/scripts/inc2h.pl: changed definition of BIT_AT
5301 to emit 'sbit at' instead of 'bit at'. This was a request.
5303 PIC16 port related preliminary changes:
5304 * gen.c: prefixed function popRegFromString with
5305 pic16_ and all references to it corrected
5306 * pcode.c: all pic16_pc_* hardware registers prefixed
5307 with underscore (_),
5308 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5309 * ralloc.c: newReg(): when register is REG_SFR then
5310 set address to rIdx,
5311 pic16_allocProcessorRegister(): marks register wasUsed=0
5312 pic16_writeUsedRegs(): added a call to assign processor
5313 registers via pic16_assignFixedRegisters
5315 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5317 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5318 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5319 variables in unused register banks. Also the SSEG is placed
5320 wherever there is enough space for it, and IDATA can be anywhere
5321 in internal RAM. For now compile using -Wl-Y[stack_size].
5322 The mem file is different for this option as well, since it
5323 makes no sense of talking about DSEG lenght.
5325 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5327 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5328 in certain cases, e.g. when ROM assignment, patch provided
5329 from Albert den Haan.
5331 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6339 If they pop r0/r1 they must be called in the opposite order than aopOp().
6340 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6341 (resp. --stack-auto), prepared for --xstack

6347 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6349 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
6350 these ports have their own __sdcc_external_start()
6352 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6354 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6355 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6356 type for bits was changed. It resulted in bit variables becoming
6357 global, which is not permitted in PIC 14 assembly output.
6359 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6361 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6363 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6365 Z80 and MCS51 linkers complaint if a public symbol is defined

6374 A few small changes that speed up the peephole optimizer.
6378 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6380 Try to make the peephole optimizer smarter by maintaining
6381 an association between the assembly source code and the
6382 iCodes that originated them. Put this information to use
6383 with a new peephole rule condition "notVolatile" so that
6384 the rules can be aggressive yet still safe.
6389 * src/mcs51/peeph.def
6391 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6395 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6396 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6397 if the left or right operand symbols have the accuse flag set.
6399 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6401 Changed the type of the result of the ! (NOT) operator to char;
6402 previously it returned the same type as the source. This allows
6403 us to eliminate all the genFloatNot functions (all of its target
6404 implementations were very buggy) since !float can use the same
6407 * src/SDCCicode.c (ast2iCode): ! returns char

6409 * src/ds390/gen.c (genNot, genNotFloat),
6410 * src/z80/gen.c (genNot, genNotFloat),
6411 * src/pic/gen.c (genNot, genNotFloat),

6416 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6417 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6418 during interrupts. Ensure WSAVE is located at a shared bank address.
6419 2. Fixed page selection in some places
6420 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6421 the registers name strings.
6422 4. Fixed "signed / unsigned compare" compiler warnings.
6423 5. The PIC port manages its own allocation of the general purpose
6424 registers, but makes no attempt to reuse them. As a result when
6425 compiling it soon runs out of general purpose registers. Some
6426 additional code was added to the files pcode.c and device.c to walk
6427 through the function call tree and rename the registers so that they
6437 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6438 genPlus() & genMinus() when the result is the same as left or right

6444 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6446 Made bitfield a distinct type from bit so that bitfields
6447 convert as per ANSI C and bits retain their traditional
6448 boolean style behaviour. Implemented bitfield support in
6456 * src/ds390/gen.c: bit v bitfield split
6457 * src/z80/gen.c: New support for bitfields
6458 * support/regression/tests/bitfields.c: reenabled z80,
6461 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6463 Rules 246.x, 247.x relate to bitfields, the others speed up
6464 access to xdata mapped I/O devices.
6466 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6468 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6470 Cleaned up genPackBits and genUnpackBits and added two helper
6471 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6472 for literal assignments in genPackBits (thanks to Frieder for
6478 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6480 Fixed bug #748310 (pointer to function type mishandled when the
6481 function name is omitted). Also fixed a SIGSEGV when a function
6482 attribute (reentrant, etc) is used on a non-function or on a
6483 function but misplaced before the parameter list.
6485 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6487 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6510 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6512 Made the constant following the "interrupt" keyword optional. If
6513 omitted, the function will not automatically be given an entry
6514 in the interrupt vector table (similar to #pragma NOIV, but
6515 less syntacticly kludgy). The interrupt number is also now
6516 range checked. Also fixed a bug in the high order bit example

6530 * src/SDCCicode.c (operandOperation): rewritten some ops
6531 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6532 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6534 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6535 be re-activated by defining REDUCE_LITERALS)
6536 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6537 unsigned, but are signed by default
6538 * src/SDCCval.c (constVal): rearranged
6539 * src/SDCCval.c (valMod): preliminary fix
6540 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6992 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6993 the regression tests I'm not brave enough to enable 245.b, 245.c
6994 * doc/sdccman.lyx: added latex preamble for hyperref package.
6995 Using pdflatex this will give you a hyperlinked pdf file with
6996 bookmarks. (prepend '%' before /usepackage if this breaks something)

7012 Applied patch from bug 737905 (renamed yylineo to mylineno):
7019 * src/pic16/pcode.c: Cleaned warnings
7020 * src/pic16/pcodeflow.c: Cleaned warnings
7021 * src/pic16/pcoderegs.c: Cleaned warnings

7037 it can be defined with CFLAGS when running configure
7038 * src/SDCCmain.c: fixed compiling + linking with object files
7040 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7043 added --disable-pic16-port
7044 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7045 * src/SDCCmain.c: linkOptions is changed to set *,
7046 added if/endif conditional macros to remove options help
7047 messages from optionsTable when a port is not configured, added
7048 support for the PIc16 port in the ports table, when executing
7049 the compiler with no port specified on command line, a default
7050 port is selected with the new macro DEFAULT_PORT which is
7051 defined in port.h, in setDefaultOptions() linkOptions is removed
7052 from initialization assignment, since now it is a set,
7053 parseCmdLine uses setParseWithComma for linkOptions, in
7054 linkEdit() linkOptions are accessed with new function indexSet()
7055 which returns the i'th item of a set variable. See SDCCset.c, in
7056 linkEdit() when calling buildCmdLine(), added linkOptions as
7057 last argument. Now users can pass arguments to gplink via the
7058 -Wl option, main() uses pic16glue() to glue up pic16 programs
7059 * src/SDCCpeeph.c: various changes to support pic16

7070 * src/pic16/glue.c: commented out some error producing lines
7071 * src/pic16/main.c: __config directives are commented out to stop
7072 gpasm complaining and test the linkage with gplink, _linkCmd and
7073 _asmCmd changed to be more gplink and gpasm friendly
7074 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7075 produced an error when parsed, peep rule 12 is added to utilize
7076 movff, but it is commented out since the pCode does not support
7077 yet a command with 2 address arguments
7079 2003-05-18 <johan AT balder>
7081 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7082 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7108 2003-05-11 Borut Razem <borut.razem AT siol.net>
7110 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7111 the path of bin directory, so that PATH is the only env. variable, which has to be set
7112 in case of standard installation.

8142 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8144 * in \sdcc\as\mcs51\ changed these files in order to create an
8145 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8146 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8147 following files to include the previous two files: aslink.dsp,
8148 Makefile.aslink, Makefile.bcc, and Makefile.in.
8150 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8151 .adb instead of .cdb
8153 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8155 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8156 value from option --iram-size.
8158 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8160 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8163 2002-09-18 <wiml AT hhhh.org>
8165 * SDCClrange.h: exposed setFromRange() and setToRange()
8166 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8167 packRegsForAccUse() (bug 542397)
8168 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8169 multiple times and emitting the fetch operations more than once
8170 added aopGetUsesAcc() function to allow binary operators to
8171 fetch their operands in the correct order; made genMinus() emit
8172 compact code for X = LITERAL - Y
8174 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8175 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8176 sprintf() in line 1267.
8178 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8179 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8182 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8183 Changes to aslink (All the changes are marked with 'JCF'):
8185 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8188 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8189 area BSEG. Also moves, if possible, the DATA area down into the internal
8190 ram so more space is available.
8192 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8195 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8196 not bytes. Function summary() which creates a memory usage summary
8197 file with extension .mem. Reports of overlaping stack and small stack
8198 size. If the space for the stack is less than 16 bytes aslink trows a
8201 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8202 the 8051. Option 'y' for memory summary output file.
8204 Changes to sdcc (All the changes are marked with 'JCF'):
8206 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8208 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8209 overlaying area for it (uses RegBankUsed[4]).
8211 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8212 bank zero as used by default. By default aslink locates the stack
8213 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8214 the creation of the .mem file. Delegates the allocation of data area
8215 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8216 the begining of the stack area to aslink.
8218 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8219 glue() in SDCCglue.c creates an area for it.
8221 2002-09-03 Borut Razem <borut.razem AT siol.net>
8222 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8223 sdcc/src/pic/glue.c:
8224 introduced atexit() handler for teporay files removal in case of
8225 errors, assertions, ...
8227 2002-08-29 Borut Razem <borut.razem AT siol.net>
8228 * sdcc/support/cpp2/auto-host_vc_in.h:
8229 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8230 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8231 Maybe there is a similar problem with BORLANDC? It should be checked!
8233 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8234 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8235 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8236 was not executed, and the compiler (cl) launched a warning:
8237 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8239 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8240 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8242 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

8251 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8252 - added Release configuration in VS projects
8253 - review of compiler an linker options
8254 - VC .exe files are generated in bin_vc directory, not to interfere
8255 with binaries generated from other projects (cygwin, mingw, bcc ...)
8257 * sdcc/src/yacc.dsp: added
8259 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8260 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8261 and insert the version number definitions from .version
8263 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8265 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

8269 removed from CVS, generated automatically
8271 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8272 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8274 2002-08-11 Borut Razem <borut.razem AT siol.net>
8275 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8277 2002-08-10 Borut Razem <borut.razem AT siol.net>
8278 * src/SDCCmain.c (main):
8279 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8280 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8281 The consequence was that some temporary files were not removed.
8284 unification of code in functions tempfilename() and tempfile():
8285 function tempnam() is defined in Visual Studio 6.0 and .NET
8287 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8289 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8290 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8291 - removed compiler command line option /WX: Treats all warnings as errors
8292 - update a list of source files, included into the project
8294 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8295 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8296 changed project type to Generic Project so that can be correcly converted to VS.NET project
8298 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8300 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8302 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8304 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8305 added return 0 statements after assert() to make compiler happy
8307 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8308 added newline in the def file to keep MSC compiler satisfied
8310 * sdcc/src/z80/gen.c:
8311 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8312 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8313 - solved MSC error in function aopDump()
8315 * sdcc_vc.h: define PREFIX as "\\sdcc"
8317 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

8369 Initialized the new field char *Processor field to NULL in all ports
8372 Compiler generated registers for interrupt context saving
8373 were not getting allocated.
8375 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8378 Fixed left shift. Will promote the left side of a left shift
8379 if a) left shifting more than size of operand or b) when assigned
8380 to something size > size of left side
8382 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8490 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8492 * sdcc/src/SDCCloop.c:
8493 Previous fix was not good. basic blocks that have "break" or "return" are
8494 not really partof a loop , but live ranges used in these blocks should
8495 be live thru the entire loop, so set partOfLoop but don't add them to
8498 2002-02-21 <johan AT FRIJA>
8500 * src/SDCCcse.c: fixed bug #514308
8502 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8527 Karl and Johan start ucsim XA support. Most dissassembly working,
8528 about 75% emulation done(plenty of work remaining).
8530 * sim/ucsim/z80.src:
8531 Add Z80 support to ucsim, add test-ucz80 regression test,
8532 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9371 * 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.
9373 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
9375 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
