1131 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1133 * device/lib/printf_large.c: removed inline assembly for portability and
1134 readability. Use printf_fast if speed or size are more important.
1135 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1136 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1138 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1140 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1141 prevent compiler warning
1143 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1145 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1146 moved to level 0 and declared as static. Also they are explicit
1147 placed in access bank. This was necessery because some times they
1148 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1149 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1150 optimizations. Currently only compare to unsigned char is implemented,
1151 * src/pic16/gen.c: added fReturnIdx array,
1152 * (struct resolvedIfx) is moved to gen.h and made public,
1153 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1154 * (aopForSym): added an optimization to directly store in stack of
1155 the operand of a SEND iCode,
1156 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1157 but as registers instead (AOP_REG) using the fReturnIdx array,
1158 * (pic16_freeAsmop): remove the freed register from the
1159 _G.sregsAlloc field,
1160 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1161 a compare of 'WREG',
1162 * (pic16_popGetTempRegCond): changed function prototype, now
1163 function takes also a bitVector argument v which holds the current
1164 set of registers that are allocated for stack access by aopForSym,
1165 registers allocated in aopForSym for accessing stack symbols are not
1166 any more part of the functions usedRegs field,
1167 * (genCall): some times aopOp is called for a stack variable to be
1168 send, aopForSym might perform the push, if this is true make sure
1169 that genCall doesn't push the variable twice by testing _G.resDirect,
1170 * (genFunction): changed testing for unspecified interrupt number
1171 from 256 to INTNO_UNSPEC,
1172 * modified selection scheme of frame pointer generation. Previously
1173 if function did use local registers a frame pointer was generated,
1174 now a frame pointer is generated only if function has arguments
1175 (that need PLUSW2 register access), or has stack arguments, or the
1176 compiler is not instructed to omit the frame pointer,
1177 * (genEndFunction): before restoring local registers that were saved
1178 in the function preamble, also restore the registers that *might*
1179 have been allocated for stack access,
1180 * (genRet): removed some old comments,
1181 * (genCmp, the active (RN's) version): added a call to the
1182 pic16_genCmp_special function to perform the compare with a more
1183 robust and optimized way,
1184 * (genInline): a feature has been added in inline code generation,
1185 which allows a wildcard variable substitution when writing inline
1186 assembly. Code is incomplete and experimental therefore undocumented,
1187 * (genCast): changed order of aopOp for result and right to allow
1188 aopForSym to directly load the result if possible,
1189 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1190 perform an optimized compare on some selected special occasions,
1191 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1192 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1193 generate an IVT any more,
1194 * src/pic16/main.c (pic16_optionsTable): added command line option
1196 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1197 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1199 * src/pic16/NOTES: Raphael Neider added in list of active developers
1200 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1201 jumptable_end to prevent bug #,
1202 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1203 inCond and outCond fields,
1204 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1205 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1206 turn off register spilling,
1207 * (packRegsForOneUse): synced with other ports' versions although it
1208 is not used currently,
1209 * (pic16_packRegisters): added an optimization while reading
1210 structure bitfields, some registers may be saved (malloc code is
1211 decreased by 80 bytes)
1213 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1215 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1216 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1217 this can be optimized more?
1219 2005-03-10 Raphael Neider <rneider AT web.de>
1221 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1222 genNearPointerGet): (hopefully) fixed access to bitfields via
1223 pointers (p->bitN = x; and x = p->bitN; failed)

1857 Adding support for replacing ljmps with sjmps in jumptables
1858 generated for switch statements. For now you need to set the
1859 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1860 Now 4 algorithms for mcs51 jumptable generation are used:
1861 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1862 addresses loaded pc-relative for up to 112 cases and stack-pushing

1893 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1895 * added libc directory. The current version of LibC contains string
1896 functions, ctype functions and macros and some functions of the
1897 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1898 be extensively tested in the future. Standard disclaimer here.
1899 Library is not automatically build yet. But one can build it by
1900 invoking 'make' inside the libc directory.
1901 * added ADC library under libio. Preliminary version yet.

1911 * (pic16_storeForReturn): optimized return of 0,
1912 * (genCmp): experimental code for new genCmp which uses PIC18's
1913 special compare&skip instructions. Initial tests fail some times
1914 with variables grater than 1 byte in size, so new code is disabled,
1915 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1917 * (genCast): began a fix to optimize the casting of a bit to another
1918 bit, now assigning a bitfield to another bitfield will fail, sorry,
1919 * src/pic16/main.c: disabled the use of lr-support feature,
1920 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1923 bits with offset (case PO_GPR_BIT),
1924 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1926 * (isBankInstruction): modified to return 0 for no banking instruction,
1927 and 1 for banking instruction,
1928 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1929 caused stop processing pCodes after a inline assembly block,
1930 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1932 registers when it shouldn't,
1933 * src/pic16/ralloc.c (allocReg): add preliminary support for
1934 supporting a limited set of temporary registers,
1936 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1942 (genFunction): optimize RECEIVE iCodes in reentrant functions
1944 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4844 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
4847 * support/regression/generate-cases.py (main): Changed from inline
4850 * doc/Makefile (install): Changed to depth first to get rid of
4851 missing directory install warning.
4853 * as/Makefile (install-doc): Made work on Mac.
4855 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4857 * src/SDCCast.c: added an additional type flow in decorateType() of
4858 opposite direction, see feature request #860006; it's enabled at runtime
4859 by setting the environment variable SDCC_NEWTYPEFLOW
4860 * src/SDCCast.h: changed prototype of decorateType()
4861 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4862 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4863 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4864 see feature request #877103
4865 * src/SDCCval.c: updated call of decorateType()
4866 (valBitwise): fixed bug #882876
4867 (valMinus): added promotion
4868 (valLogicAndOr): result is unsigned
4869 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4870 * src/SDCCsymt.c (computeType),
4871 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4872 must not cause an unsigned operation
4873 * src/pic/glue (pic14emitRegularMap),
4874 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
4876 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

4893 * src/pic/ralloc.h: applied patch from Slade Rich;
4894 added support for multiple code pages and multiple RAM banks on the
4895 PIC 14 port. The ASM files now no longer simply assume all the
4896 code / RAM are in the same page / bank. This means the linker can
4897 safely allocate code/RAM of separate ASM files to different pages/banks.
4898 * doc/sdccman.lyx: added Slade's tips
4899 * src/mcs51/peeph.def: fixed bug #880768

4911 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4912 strtof is not part of C89 and isn't included with Mac OS X.
4914 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4916 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4941 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4943 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4944 loaded with the linker search paths (-L arguments) and the libraries
4945 to be linked with the current source (-l arguments). Changes
4946 currently will affect only the pic16 port.
4947 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4948 include path the port specific paths and port specific libraries,
4949 * gplink command now contains the $3 argument,
4950 * src/pic16/device.h,
4951 * src/pic16/device.c,: structure PIC_device is made public and
4952 renamed to PIC16_device, the same for variable Pics which is renamed

4967 Documenting changes from previous commits.
4968 * configure.in (version 1.56),
4969 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4970 when generating output files to configure the pic16 library,
4971 but now I've commented it out, since gputils aren't installed in the
4972 SF compile farm, so library won't compile
4974 * device/lib/Makefile.in (version 1.56): initially I've added in
4975 target 'all' the prerequestive 'model-pic16' so it compiled the
4976 pic16 library, but now I've commented it out for the same reasons
4978 * added targets 'model-pic16' and 'objects-pic16' to compile the
4980 * added target 'port-specific-objects-pic16' to handle the
4981 generated libraries and copy them into the build/ directory
4982 * added target 'clean-intermediate-pic16' to clean intermediate
4983 files into pic16 directory
4984 * in target 'installdirs' added line to create directory pic16 in
4985 the installation path
4987 * device/include/Makefile.in (version 1.11): in target 'install'
4988 added lines to copy all header files to installation path,
4989 * in target 'installdirs' added line create directory for pic16
4990 headers in the installation path

5005 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5006 option so that it actually works. Made it specific to the z80, since
5007 the gbz80 doesn't have these kinds of I/O ports.
5009 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5011 * device/include/z180.h,

5033 Mainly changes to support compilation of the device libraries
5034 * src/pic16/device.c: stack is allocated via symbol and not
5035 via literal number. The symbol is placed in the corresponding
5036 position of the data ram
5037 * (pic16_dump_section): relocatable and absolute uninitialized
5038 data are now emitted in sorted order to reduce section naming,
5039 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5040 weren't marked as being in the access bank,
5042 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5044 Added portion of GNU PIC Library under the directory
5045 device/include/pic16 and device/lib/pic16. These files
5046 contain the declarations of SFRs for the PIC18Fxx2 devices.
5047 The directory is initialized via configure from toplevel.
5049 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5051 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5077 all over. Telling LaTeX to be less strict with word spacing
5078 to better keep the right margin. Changed some notes about
5079 maintainance of the ports in section 3.2.1 - is it OK like this?
5081 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5119 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5121 * src/pic16/peeph.def: all peepholes with movff are commented out,
5122 because there is a problem in the pcode peep optimizer,
5123 * src/pic16/ralloc.c: the register allocator can now reuse local

5262 Bug reported from Jesus Calvino-Fraga
5264 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5266 * sdcc.spec: updated
5267 * device/include/Makefile.in: don't install CVS directories
5268 * device/lib/Makefile.in: added removal of CVS directories after install
5269 * doc/Makefile: fixed install, added local_icons
5270 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5271 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5272 * src/ds390/gen.c (genRightShift): fixed bug #870788
5273 * src/SDCCast.c (decorateType): fixed bug #870781
5275 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5277 PIC16 port related changes:
5278 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5279 added variable stackPos,
5281 * gen.c: genCall, assignResultValue: added support for
5282 pushing/retrieving function parameters to/from stack,
5283 genFunction,genEndFunction: setup stack frame for the
5285 genAddrOf: will be changed according to bug 863624
5287 * added files genutils.c and genutils.h which contain gen*
5288 debugged and optimised functions extracted from gen.c
5290 * glue.c: added variable 'externs' which holds extern symbols,
5291 pic16emitRegularMap: is modified to properly handle relocatable
5292 symbols under the new scheme,
5293 pic16createInterruptVect: is modified
5294 pic16printPublics: is modified to emit 'global' assembler directives,
5295 added pic16_printExterns to print extern symbols,
5296 pic16glue: initializes stack/frame pointer in the beginning of
5297 the assembly output. Temporary hack, will be corrected later,
5298 because gplink yet does not support stack and SDCC does not
5299 yet support a type of crt0.o object to create the final binary.
5301 * Removed many lines that contain 8051 legacy code.
5302 * The code is finally placed under a 'code' directive.
5303 * Added port specific options.
5305 * _process_pragma: simplified since now we do not need *special*
5306 include file to define SFR registers. But a separate header
5307 will be needed. This will be developed later.
5308 * _pic16_parseOptions: added, parses port specific options:
5309 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5310 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5311 --preplace-udata-with=
5313 * _pic16_setDefaultOptions: modified to initialize section names,
5314 but hack is temporarly out of order since it needs improvement.
5315 * _pic16_genAssemblerPreamble: configuration words are emitted by
5316 their address instead of their name. This part is incomplete and
5317 supports only the 18Fxx2 devices. Other devices will emit an error
5318 during assembly since they do not contain the same set of config
5320 * _pic16_genIVT: is modified,
5322 * pcode.c: added definitions for some hardware registers that are needed
5324 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5325 All PCI entries are updated. Now LFSR is supported.
5326 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5327 * added pic16_newpCodeOpLit2 to support instructions with
5328 two literal arguments
5329 * pic16_pCode2str: corrected code that emits assembler instructions
5330 with two literal operands and those that have an access bit modifier
5331 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5332 this fixes a bug which caused some labels to be lost, when an
5333 assembler directive was added, i.e. banksel,
5334 * pic16_FixRegisterBanking: improved logic that causes the insertion
5336 * InlineFunction: functions that are called once, are not any more
5337 inlined. This can be a port option in the future,
5339 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5341 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5342 hold the corresponding uninitialized symbols,
5343 * pic16_allocProcessorRegister: registers have explicit marked the
5345 * pic16_allocInternalRegister: registers are explicit marked as
5347 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5348 processing list, so bit registers were lost,
5351 * ralloc.h: added field 'accessBank' and original symbol operand
5352 in register definition,
5353 * removed the field isMapped from register definition,
5355 ** Several functions have been removed from various sources:
5356 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5357 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5358 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5359 pic16_assignRelocatableRegisters
5361 ** others have been introduced:
5362 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5363 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5365 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5367 * support/scripts/inc2h.pl: changed definition of BIT_AT
5368 to emit 'sbit at' instead of 'bit at'. This was a request.
5370 PIC16 port related preliminary changes:
5371 * gen.c: prefixed function popRegFromString with
5372 pic16_ and all references to it corrected
5373 * pcode.c: all pic16_pc_* hardware registers prefixed
5374 with underscore (_),
5375 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5376 * ralloc.c: newReg(): when register is REG_SFR then
5377 set address to rIdx,
5378 pic16_allocProcessorRegister(): marks register wasUsed=0
5379 pic16_writeUsedRegs(): added a call to assign processor
5380 registers via pic16_assignFixedRegisters
5382 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5384 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5385 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5386 variables in unused register banks. Also the SSEG is placed
5387 wherever there is enough space for it, and IDATA can be anywhere
5388 in internal RAM. For now compile using -Wl-Y[stack_size].
5389 The mem file is different for this option as well, since it
5390 makes no sense of talking about DSEG lenght.
5392 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5394 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5639 * src/SDCCast.c (decorateType): disabled a transformation I added in
5640 revision 1.188 (access to fields of a structure at an absolute address);
5641 it breaks with bitfields, extern declarations, and gcse analysis.
5642 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5643 could be assigned through a pointer, so don't complain.

5751 xdata initialization slightly shorter
5753 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6400 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6401 fetching of the pointer
6402 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6403 copied from genNearPointerSet()
6404 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6405 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6419 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6421 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6422 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6423 type for bits was changed. It resulted in bit variables becoming
6424 global, which is not permitted in PIC 14 assembly output.
6426 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6428 * doc/sdccman.lyx: various additions and updates. Rearranged sections
6430 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6432 Z80 and MCS51 linkers complaint if a public symbol is defined
6433 in more than one library module:

6439 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6441 A few small changes that speed up the peephole optimizer.
6445 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6447 Try to make the peephole optimizer smarter by maintaining
6448 an association between the assembly source code and the
6449 iCodes that originated them. Put this information to use
6450 with a new peephole rule condition "notVolatile" so that
6451 the rules can be aggressive yet still safe.
6456 * src/mcs51/peeph.def
6458 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6462 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6463 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6464 if the left or right operand symbols have the accuse flag set.
6466 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6468 Changed the type of the result of the ! (NOT) operator to char;
6469 previously it returned the same type as the source. This allows
6470 us to eliminate all the genFloatNot functions (all of its target
6471 implementations were very buggy) since !float can use the same
6474 * src/SDCCicode.c (ast2iCode): ! returns char
6475 * src/mcs51/gen.c (genNot, genNotFloat),
6476 * src/ds390/gen.c (genNot, genNotFloat),
6477 * src/z80/gen.c (genNot, genNotFloat),
6478 * src/pic/gen.c (genNot, genNotFloat),
6479 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6481 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6483 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6484 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6485 during interrupts. Ensure WSAVE is located at a shared bank address.
6486 2. Fixed page selection in some places
6487 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6488 the registers name strings.
6489 4. Fixed "signed / unsigned compare" compiler warnings.
6490 5. The PIC port manages its own allocation of the general purpose
6491 registers, but makes no attempt to reuse them. As a result when
6492 compiling it soon runs out of general purpose registers. Some
6493 additional code was added to the files pcode.c and device.c to walk
6494 through the function call tree and rename the registers so that they
6504 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6505 genPlus() & genMinus() when the result is the same as left or right

6511 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6513 Made bitfield a distinct type from bit so that bitfields
6514 convert as per ANSI C and bits retain their traditional
6515 boolean style behaviour. Implemented bitfield support in
6523 * src/ds390/gen.c: bit v bitfield split
6524 * src/z80/gen.c: New support for bitfields
6525 * support/regression/tests/bitfields.c: reenabled z80,
6528 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6530 Rules 246.x, 247.x relate to bitfields, the others speed up
6531 access to xdata mapped I/O devices.
6533 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6535 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6537 Cleaned up genPackBits and genUnpackBits and added two helper
6538 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6539 for literal assignments in genPackBits (thanks to Frieder for
6545 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6547 Fixed bug #748310 (pointer to function type mishandled when the
6548 function name is omitted). Also fixed a SIGSEGV when a function
6549 attribute (reentrant, etc) is used on a non-function or on a
6550 function but misplaced before the parameter list.
6552 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6554 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6577 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6579 Made the constant following the "interrupt" keyword optional. If
6580 omitted, the function will not automatically be given an entry
6581 in the interrupt vector table (similar to #pragma NOIV, but
6582 less syntacticly kludgy). The interrupt number is also now
6583 range checked. Also fixed a bug in the high order bit example
6590 * support/Util/SDCCerr.c
6591 * support/Util/SDCCerr.h
6594 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6597 * src/SDCCicode.c (operandOperation): rewritten some ops
6598 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6599 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6601 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6602 be re-activated by defining REDUCE_LITERALS)
6603 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6604 unsigned, but are signed by default
6605 * src/SDCCval.c (constVal): rearranged
6606 * src/SDCCval.c (valMod): preliminary fix
6607 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6650 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6651 * src/SDCCval.c (valDiv, valMod): fixed signdness
6652 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6653 signedness of modulo, left and right shift

7059 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7060 the regression tests I'm not brave enough to enable 245.b, 245.c
7061 * doc/sdccman.lyx: added latex preamble for hyperref package.
7062 Using pdflatex this will give you a hyperlinked pdf file with
7063 bookmarks. (prepend '%' before /usepackage if this breaks something)

7101 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7103 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7104 it can be defined with CFLAGS when running configure
7105 * src/SDCCmain.c: fixed compiling + linking with object files
7107 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7110 added --disable-pic16-port
7111 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7112 * src/SDCCmain.c: linkOptions is changed to set *,
7113 added if/endif conditional macros to remove options help
7114 messages from optionsTable when a port is not configured, added
7115 support for the PIc16 port in the ports table, when executing
7116 the compiler with no port specified on command line, a default
7117 port is selected with the new macro DEFAULT_PORT which is
7118 defined in port.h, in setDefaultOptions() linkOptions is removed
7119 from initialization assignment, since now it is a set,
7120 parseCmdLine uses setParseWithComma for linkOptions, in
7121 linkEdit() linkOptions are accessed with new function indexSet()
7122 which returns the i'th item of a set variable. See SDCCset.c, in
7123 linkEdit() when calling buildCmdLine(), added linkOptions as
7124 last argument. Now users can pass arguments to gplink via the
7125 -Wl option, main() uses pic16glue() to glue up pic16 programs

7137 * src/pic16/glue.c: commented out some error producing lines
7138 * src/pic16/main.c: __config directives are commented out to stop
7139 gpasm complaining and test the linkage with gplink, _linkCmd and
7140 _asmCmd changed to be more gplink and gpasm friendly
7141 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7142 produced an error when parsed, peep rule 12 is added to utilize
7143 movff, but it is commented out since the pCode does not support
7144 yet a command with 2 address arguments
7146 2003-05-18 <johan AT balder>
7148 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7149 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7173 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7175 2003-05-11 Borut Razem <borut.razem AT siol.net>
7177 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7178 the path of bin directory, so that PATH is the only env. variable, which has to be set
7179 in case of standard installation.
7180 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8262 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8263 not bytes. Function summary() which creates a memory usage summary
8264 file with extension .mem. Reports of overlaping stack and small stack
8265 size. If the space for the stack is less than 16 bytes aslink trows a
8268 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8269 the 8051. Option 'y' for memory summary output file.
8271 Changes to sdcc (All the changes are marked with 'JCF'):
8273 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8275 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8276 overlaying area for it (uses RegBankUsed[4]).
8278 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8279 bank zero as used by default. By default aslink locates the stack
8280 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8281 the creation of the .mem file. Delegates the allocation of data area
8282 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8283 the begining of the stack area to aslink.
8285 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8286 glue() in SDCCglue.c creates an area for it.
8288 2002-09-03 Borut Razem <borut.razem AT siol.net>
8289 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8290 sdcc/src/pic/glue.c:
8291 introduced atexit() handler for teporay files removal in case of
8292 errors, assertions, ...
8294 2002-08-29 Borut Razem <borut.razem AT siol.net>
8295 * sdcc/support/cpp2/auto-host_vc_in.h:
8296 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8297 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8298 Maybe there is a similar problem with BORLANDC? It should be checked!
8300 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8301 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8302 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8303 was not executed, and the compiler (cl) launched a warning:
8304 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8306 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8307 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8309 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8310 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8312 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8313 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8314 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8315 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8316 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8317 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8318 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8319 - added Release configuration in VS projects
8320 - review of compiler an linker options
8321 - VC .exe files are generated in bin_vc directory, not to interfere
8322 with binaries generated from other projects (cygwin, mingw, bcc ...)
8324 * sdcc/src/yacc.dsp: added
8326 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8327 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8328 and insert the version number definitions from .version
8330 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8332 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8333 added - genarate auto-host.h using auto-host_vc_in.h as template
8336 removed from CVS, generated automatically
8338 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8339 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8341 2002-08-11 Borut Razem <borut.razem AT siol.net>
8342 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8344 2002-08-10 Borut Razem <borut.razem AT siol.net>
8345 * src/SDCCmain.c (main):
8346 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8347 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8348 The consequence was that some temporary files were not removed.
8351 unification of code in functions tempfilename() and tempfile():
8352 function tempnam() is defined in Visual Studio 6.0 and .NET
8354 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8356 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8357 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8358 - removed compiler command line option /WX: Treats all warnings as errors
8359 - update a list of source files, included into the project
8361 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8362 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8363 changed project type to Generic Project so that can be correcly converted to VS.NET project
8365 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8367 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8369 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8371 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8372 added return 0 statements after assert() to make compiler happy
8374 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8375 added newline in the def file to keep MSC compiler satisfied
8377 * sdcc/src/z80/gen.c:
8378 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8379 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8380 - solved MSC error in function aopDump()
8382 * sdcc_vc.h: define PREFIX as "\\sdcc"
8384 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8385 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8428 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8430 Added "char *Processor" field to the port structure.
8433 Added -p option. Allows port dependent processor to be specified.
8436 Initialized the new field char *Processor field to NULL in all ports
8439 Compiler generated registers for interrupt context saving
8440 were not getting allocated.
8442 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8445 Fixed left shift. Will promote the left side of a left shift
8446 if a) left shifting more than size of operand or b) when assigned
8447 to something size > size of left side
8449 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8557 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8559 * sdcc/src/SDCCloop.c:
8560 Previous fix was not good. basic blocks that have "break" or "return" are
8561 not really partof a loop , but live ranges used in these blocks should
8562 be live thru the entire loop, so set partOfLoop but don't add them to
8565 2002-02-21 <johan AT FRIJA>
8567 * src/SDCCcse.c: fixed bug #514308
8569 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8573 statement inside a loop, it was not being considered part of the loop.
8575 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8577 2002-02-10 Karl Bongers <karl AT turbobit.com>
8580 Fixed up SDCDB debugger somewhat. Updated debugger/README
8581 with lots of comments and notes.
8583 * device/examples/test2.c:
8584 Fix bug, "red" variable not being initialized(compiler complained).
