228 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
230 * device/lib/printf_large.c: removed inline assembly for portability and
231 readability. Use printf_fast if speed or size are more important.
232 * src/pic16/gen.c: removed conditions around use of DEBUGpc
233 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
235 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
237 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
238 prevent compiler warning
240 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
242 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
243 moved to level 0 and declared as static. Also they are explicit
244 placed in access bank. This was necessery because some times they
245 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
246 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
247 optimizations. Currently only compare to unsigned char is implemented,
248 * src/pic16/gen.c: added fReturnIdx array,
249 * (struct resolvedIfx) is moved to gen.h and made public,
250 * (struct _G): added sregsAlloc and sregsAllocSet fields,
251 * (aopForSym): added an optimization to directly store in stack of
252 the operand of a SEND iCode,
253 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
254 but as registers instead (AOP_REG) using the fReturnIdx array,
255 * (pic16_freeAsmop): remove the freed register from the
257 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
259 * (pic16_popGetTempRegCond): changed function prototype, now
260 function takes also a bitVector argument v which holds the current
261 set of registers that are allocated for stack access by aopForSym,
262 registers allocated in aopForSym for accessing stack symbols are not
263 any more part of the functions usedRegs field,
264 * (genCall): some times aopOp is called for a stack variable to be
265 send, aopForSym might perform the push, if this is true make sure
266 that genCall doesn't push the variable twice by testing _G.resDirect,
267 * (genFunction): changed testing for unspecified interrupt number
268 from 256 to INTNO_UNSPEC,
269 * modified selection scheme of frame pointer generation. Previously
270 if function did use local registers a frame pointer was generated,
271 now a frame pointer is generated only if function has arguments
272 (that need PLUSW2 register access), or has stack arguments, or the
273 compiler is not instructed to omit the frame pointer,
274 * (genEndFunction): before restoring local registers that were saved
275 in the function preamble, also restore the registers that *might*
276 have been allocated for stack access,
277 * (genRet): removed some old comments,
278 * (genCmp, the active (RN's) version): added a call to the
279 pic16_genCmp_special function to perform the compare with a more
280 robust and optimized way,
281 * (genInline): a feature has been added in inline code generation,
282 which allows a wildcard variable substitution when writing inline
283 assembly. Code is incomplete and experimental therefore undocumented,
284 * (genCast): changed order of aopOp for result and right to allow
285 aopForSym to directly load the result if possible,
286 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
287 perform an optimized compare on some selected special occasions,
288 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
289 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
290 generate an IVT any more,
291 * src/pic16/main.c (pic16_optionsTable): added command line option
293 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
294 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
296 * src/pic16/NOTES: Raphael Neider added in list of active developers
297 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
298 jumptable_end to prevent bug #,
299 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
300 inCond and outCond fields,
301 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
302 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
303 turn off register spilling,
304 * (packRegsForOneUse): synced with other ports' versions although it
305 is not used currently,
306 * (pic16_packRegisters): added an optimization while reading
307 structure bitfields, some registers may be saved (malloc code is
308 decreased by 80 bytes)
310 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
312 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
313 left is a bitfield, if yes, then don't optimize assignment. Perhaps
314 this can be optimized more?
316 2005-03-10 Raphael Neider <rneider AT web.de>
318 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
319 genNearPointerGet): (hopefully) fixed access to bitfields via
320 pointers (p->bitN = x; and x = p->bitN; failed)
322 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
324 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

366 to keep the correct label reference count when adding/removing references
367 to labels. A peephole file using this is appended to patch #1144962.

954 Adding support for replacing ljmps with sjmps in jumptables
955 generated for switch statements. For now you need to set the
956 environment variable SDCC_SJMP_JUMPTABLE to enable this.
957 Now 4 algorithms for mcs51 jumptable generation are used:
958 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
959 addresses loaded pc-relative for up to 112 cases and stack-pushing
960 target addresses loaded with offset from dptr for up to 256 cases.

988 to call when a stack overflow occurs,
989 * (malloc.h): added CVS Id tag,
990 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
992 * added libc directory. The current version of LibC contains string
993 functions, ctype functions and macros and some functions of the
994 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
995 be extensively tested in the future. Standard disclaimer here.
996 Library is not automatically build yet. But one can build it by
997 invoking 'make' inside the libc directory.
998 * added ADC library under libio. Preliminary version yet.
1000 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1008 * (pic16_storeForReturn): optimized return of 0,
1009 * (genCmp): experimental code for new genCmp which uses PIC18's
1010 special compare&skip instructions. Initial tests fail some times
1011 with variables grater than 1 byte in size, so new code is disabled,
1012 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1014 * (genCast): began a fix to optimize the casting of a bit to another
1015 bit, now assigning a bitfield to another bitfield will fail, sorry,
1016 * src/pic16/main.c: disabled the use of lr-support feature,
1017 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1020 bits with offset (case PO_GPR_BIT),
1021 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1023 * (isBankInstruction): modified to return 0 for no banking instruction,
1024 and 1 for banking instruction,
1025 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1026 caused stop processing pCodes after a inline assembly block,
1027 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1028 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1029 registers when it shouldn't,
1030 * src/pic16/ralloc.c (allocReg): add preliminary support for
1031 supporting a limited set of temporary registers,
1033 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1035 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1036 genDataPointerSet): ensure assignments always copy in MSB to LSB
1038 (loadRegFromAop): recognize CLRH optimization,
1039 (genFunction): optimize RECEIVE iCodes in reentrant functions
1041 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1043 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1044 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4038 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4040 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4041 loaded with the linker search paths (-L arguments) and the libraries
4042 to be linked with the current source (-l arguments). Changes
4043 currently will affect only the pic16 port.
4044 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4045 include path the port specific paths and port specific libraries,
4046 * gplink command now contains the $3 argument,
4047 * src/pic16/device.h,
4048 * src/pic16/device.c,: structure PIC_device is made public and
4049 renamed to PIC16_device, the same for variable Pics which is renamed
4050 to Pics16. Updated all references to them.
4051 * src/pic16/glue.c (pic16glue): corrected bug with code
4052 initialization which bypassed the variable initializations block.

4062 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4064 Documenting changes from previous commits.
4065 * configure.in (version 1.56),
4066 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4067 when generating output files to configure the pic16 library,
4068 but now I've commented it out, since gputils aren't installed in the
4069 SF compile farm, so library won't compile
4071 * device/lib/Makefile.in (version 1.56): initially I've added in
4072 target 'all' the prerequestive 'model-pic16' so it compiled the
4073 pic16 library, but now I've commented it out for the same reasons
4075 * added targets 'model-pic16' and 'objects-pic16' to compile the
4077 * added target 'port-specific-objects-pic16' to handle the
4078 generated libraries and copy them into the build/ directory
4079 * added target 'clean-intermediate-pic16' to clean intermediate
4080 files into pic16 directory
4081 * in target 'installdirs' added line to create directory pic16 in
4082 the installation path
4084 * device/include/Makefile.in (version 1.11): in target 'install'
4085 added lines to copy all header files to installation path,
4086 * in target 'installdirs' added line create directory for pic16
4087 headers in the installation path
4089 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4102 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4103 option so that it actually works. Made it specific to the z80, since
4104 the gbz80 doesn't have these kinds of I/O ports.
4106 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4108 * device/include/z180.h,

4115 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
4116 * src/z80/main.c (_process_pragma): add support for pragmas bank and
4117 portmode; added deprecation warning for bank= and protmode= forms.
4118 Also, guard against buffer overflow.
4119 * src/z80/gen.c (aopGet): generate better code for sfr banked read
4121 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4123 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4124 changed interrupt vector table generation to only emit declared vectors.
4125 * device/include/Makefile.in: added missing backslash
4126 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
4128 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4130 Mainly changes to support compilation of the device libraries
4131 * src/pic16/device.c: stack is allocated via symbol and not
4132 via literal number. The symbol is placed in the corresponding
4133 position of the data ram
4134 * (pic16_dump_section): relocatable and absolute uninitialized
4135 data are now emitted in sorted order to reduce section naming,
4136 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4137 weren't marked as being in the access bank,
4139 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4141 Added portion of GNU PIC Library under the directory
4142 device/include/pic16 and device/lib/pic16. These files
4143 contain the declarations of SFRs for the PIC18Fxx2 devices.
4144 The directory is initialized via configure from toplevel.
4146 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4148 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4149 the spilllocations to be compared correctly
4151 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4153 * src/SDCCast.c (decorateType): fixed bug introduced today
4155 2004-01-12 Borut Razem <borut.razem AT siol.net>
4157 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4160 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4162 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4163 in simpler and even better code
4165 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4167 * src/SDCCicode.c (operandOperation): fixed bug #874819

4171 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4173 * doc/sdccman.lyx: Moved and added some sections, small changes
4174 all over. Telling LaTeX to be less strict with word spacing
4175 to better keep the right margin. Changed some notes about
4176 maintainance of the ports in section 3.2.1 - is it OK like this?
4178 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4180 SDCC source changes:
4181 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4214 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4215 UPPER for immediate operands,
4216 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4218 * src/pic16/peeph.def: all peepholes with movff are commented out,
4219 because there is a problem in the pcode peep optimizer,
4220 * src/pic16/ralloc.c: the register allocator can now reuse local
4221 function symbols for another function. This saves register usage.
4222 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4224 Added file src/pic16/NOTES with information about program writing on
4225 the current port version.

4234 * src/SDCCmain.c : fixed #872250: -l command line defined library
4235 files are scanned before standard library files
4237 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4254 gen51Code): more efficient parameter receive for --model-large
4257 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4260 * src/z80/main.c: added missed needLinkerScript flags (more than
4261 one port structure defined in these file)
4262 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
4265 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

4278 needLinkerScript flag
4280 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4281 * src/pic/glue.c: added variable udata_section_name to
4282 override default uninitialized data segment definition for
4283 devices only with SHAREBANK memory (reported from Erik Epetrich)
4284 * (pic14emitOverlay): modified to emit a commented overlay segment
4285 directive when no overlay data exist
4286 * (picglue): modified to emit uninitialized data segment
4287 according to udata_section_name
4288 * src/pic/main.c (_pic14_parseOptions): added command line

4292 arguments via -W option
4293 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4294 object file from '.rel' to '.o' in port->linker structure,
4295 changed size of fptr from 2 to 3 in port structure
4297 2004-01-07 Borut Razem <borut.razem AT siol.net>
4299 * support/scripts/sdcc.nsi: update PATH
4300 * support/scripts/sdcc.ico: craeted
4302 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4304 * device/include/Makefile.in: fix install
4305 * doc/Makefile: fix install
4307 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4309 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4311 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4312 how the function variable allocation summary is displayed; also
4313 include information about variables allocated to the overlay
4316 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4318 * as/mcs51/lkmain.c: Help about -Y option

4328 LEFT_OP (left shift)
4330 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4332 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4333 (default behaviour).
4335 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4337 A python script to validate compiler diagnostic messages. It can be
4338 used to verify that sdcc complains about bad c source code and
4339 gives a good location of the error.
4340 * support/valdiag/Makefile,
4341 * support/valdiag/valdiag.py,
4342 * support/valdiag/tests/*
4344 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4346 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4347 * src/SDCCsymt.c (newEnumType),

4355 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4357 * src/common.h: added ifndef/define/endif macros
4358 around the header file.
4359 Bug reported from Jesus Calvino-Fraga
4361 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4363 * sdcc.spec: updated
4364 * device/include/Makefile.in: don't install CVS directories
4365 * device/lib/Makefile.in: added removal of CVS directories after install
4366 * doc/Makefile: fixed install, added local_icons
4367 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4368 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4369 * src/ds390/gen.c (genRightShift): fixed bug #870788
4370 * src/SDCCast.c (decorateType): fixed bug #870781
4372 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4374 PIC16 port related changes:
4375 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4376 added variable stackPos,
4378 * gen.c: genCall, assignResultValue: added support for
4379 pushing/retrieving function parameters to/from stack,
4380 genFunction,genEndFunction: setup stack frame for the
4382 genAddrOf: will be changed according to bug 863624
4384 * added files genutils.c and genutils.h which contain gen*
4385 debugged and optimised functions extracted from gen.c
4387 * glue.c: added variable 'externs' which holds extern symbols,
4388 pic16emitRegularMap: is modified to properly handle relocatable
4389 symbols under the new scheme,
4390 pic16createInterruptVect: is modified
4391 pic16printPublics: is modified to emit 'global' assembler directives,
4392 added pic16_printExterns to print extern symbols,
4393 pic16glue: initializes stack/frame pointer in the beginning of
4394 the assembly output. Temporary hack, will be corrected later,
4395 because gplink yet does not support stack and SDCC does not
4396 yet support a type of crt0.o object to create the final binary.
4398 * Removed many lines that contain 8051 legacy code.
4399 * The code is finally placed under a 'code' directive.
4400 * Added port specific options.
4402 * _process_pragma: simplified since now we do not need *special*
4403 include file to define SFR registers. But a separate header
4404 will be needed. This will be developed later.
4405 * _pic16_parseOptions: added, parses port specific options:
4406 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4407 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4408 --preplace-udata-with=
4410 * _pic16_setDefaultOptions: modified to initialize section names,
4411 but hack is temporarly out of order since it needs improvement.
4412 * _pic16_genAssemblerPreamble: configuration words are emitted by
4413 their address instead of their name. This part is incomplete and
4414 supports only the 18Fxx2 devices. Other devices will emit an error
4415 during assembly since they do not contain the same set of config
4417 * _pic16_genIVT: is modified,
4419 * pcode.c: added definitions for some hardware registers that are needed
4421 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4422 All PCI entries are updated. Now LFSR is supported.
4423 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4424 * added pic16_newpCodeOpLit2 to support instructions with
4425 two literal arguments
4426 * pic16_pCode2str: corrected code that emits assembler instructions
4427 with two literal operands and those that have an access bit modifier
4428 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4429 this fixes a bug which caused some labels to be lost, when an
4430 assembler directive was added, i.e. banksel,
4431 * pic16_FixRegisterBanking: improved logic that causes the insertion
4433 * InlineFunction: functions that are called once, are not any more
4434 inlined. This can be a port option in the future,
4436 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4438 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4439 hold the corresponding uninitialized symbols,
4440 * pic16_allocProcessorRegister: registers have explicit marked the
4442 * pic16_allocInternalRegister: registers are explicit marked as
4444 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4445 processing list, so bit registers were lost,
4448 * ralloc.h: added field 'accessBank' and original symbol operand
4449 in register definition,
4450 * removed the field isMapped from register definition,
4452 ** Several functions have been removed from various sources:
4453 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4454 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4455 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4456 pic16_assignRelocatableRegisters
4458 ** others have been introduced:
4459 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4460 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4462 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4464 * support/scripts/inc2h.pl: changed definition of BIT_AT
4465 to emit 'sbit at' instead of 'bit at'. This was a request.
4467 PIC16 port related preliminary changes:
4468 * gen.c: prefixed function popRegFromString with
4469 pic16_ and all references to it corrected
4470 * pcode.c: all pic16_pc_* hardware registers prefixed
4471 with underscore (_),
4472 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4473 * ralloc.c: newReg(): when register is REG_SFR then
4474 set address to rIdx,
4475 pic16_allocProcessorRegister(): marks register wasUsed=0
4476 pic16_writeUsedRegs(): added a call to assign processor
4477 registers via pic16_assignFixedRegisters
4479 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4481 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4482 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4483 variables in unused register banks. Also the SSEG is placed
4484 wherever there is enough space for it, and IDATA can be anywhere
4485 in internal RAM. For now compile using -Wl-Y[stack_size].
4486 The mem file is different for this option as well, since it
4487 makes no sense of talking about DSEG lenght.
4489 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4491 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4492 in certain cases, e.g. when ROM assignment, patch provided
4493 from Albert den Haan.
4495 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4501 (usualBinaryConversions): added support for promotion of char
4502 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
4503 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)

4506 (geniCodeArray): ditto
4507 * src/SDCCicode.h: made geniCodeCast() static: removed prototype
4508 * src/SDCCsymt.c (computeType): added more support for char;
4509 promotion of char is selectable by promoteCharToInt, fixed signedness

5502 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5503 If they pop r0/r1 they must be called in the opposite order than aopOp().
5504 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5505 (resp. --stack-auto), prepared for --xstack

5514 these ports have their own __sdcc_external_start()
5516 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5518 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5519 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5520 type for bits was changed. It resulted in bit variables becoming
5521 global, which is not permitted in PIC 14 assembly output.
5523 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5525 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5538 A few small changes that speed up the peephole optimizer.
5542 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5544 Try to make the peephole optimizer smarter by maintaining
5545 an association between the assembly source code and the
5546 iCodes that originated them. Put this information to use
5547 with a new peephole rule condition "notVolatile" so that
5548 the rules can be aggressive yet still safe.
5553 * src/mcs51/peeph.def
5555 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5559 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5560 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5561 if the left or right operand symbols have the accuse flag set.
5563 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5565 Changed the type of the result of the ! (NOT) operator to char;
5566 previously it returned the same type as the source. This allows
5567 us to eliminate all the genFloatNot functions (all of its target
5568 implementations were very buggy) since !float can use the same
5571 * src/SDCCicode.c (ast2iCode): ! returns char

5580 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5581 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5582 during interrupts. Ensure WSAVE is located at a shared bank address.
5583 2. Fixed page selection in some places
5584 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5585 the registers name strings.
5586 4. Fixed "signed / unsigned compare" compiler warnings.
5587 5. The PIC port manages its own allocation of the general purpose
5588 registers, but makes no attempt to reuse them. As a result when
5589 compiling it soon runs out of general purpose registers. Some
5590 additional code was added to the files pcode.c and device.c to walk
5591 through the function call tree and rename the registers so that they
5601 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5608 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5610 Made bitfield a distinct type from bit so that bitfields
5611 convert as per ANSI C and bits retain their traditional
5612 boolean style behaviour. Implemented bitfield support in
5620 * src/ds390/gen.c: bit v bitfield split
5621 * src/z80/gen.c: New support for bitfields
5622 * support/regression/tests/bitfields.c: reenabled z80,
5625 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5627 Rules 246.x, 247.x relate to bitfields, the others speed up
5628 access to xdata mapped I/O devices.
5630 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5632 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5634 Cleaned up genPackBits and genUnpackBits and added two helper
5635 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5636 for literal assignments in genPackBits (thanks to Frieder for
5642 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5644 Fixed bug #748310 (pointer to function type mishandled when the
5645 function name is omitted). Also fixed a SIGSEGV when a function
5646 attribute (reentrant, etc) is used on a non-function or on a
5647 function but misplaced before the parameter list.
5649 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5651 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5674 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5676 Made the constant following the "interrupt" keyword optional. If
5677 omitted, the function will not automatically be given an entry
5678 in the interrupt vector table (similar to #pragma NOIV, but
5679 less syntacticly kludgy). The interrupt number is also now
5680 range checked. Also fixed a bug in the high order bit example

5701 unsigned, but are signed by default
5702 * src/SDCCval.c (constVal): rearranged
5703 * src/SDCCval.c (valMod): preliminary fix
5704 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6156 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6157 the regression tests I'm not brave enough to enable 245.b, 245.c
6158 * doc/sdccman.lyx: added latex preamble for hyperref package.
6159 Using pdflatex this will give you a hyperlinked pdf file with
6160 bookmarks. (prepend '%' before /usepackage if this breaks something)

6176 Applied patch from bug 737905 (renamed yylineo to mylineno):
6183 * src/pic16/pcode.c: Cleaned warnings
6184 * src/pic16/pcodeflow.c: Cleaned warnings
6185 * src/pic16/pcoderegs.c: Cleaned warnings

6198 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6200 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6201 it can be defined with CFLAGS when running configure
6202 * src/SDCCmain.c: fixed compiling + linking with object files
6204 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6207 added --disable-pic16-port
6208 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6209 * src/SDCCmain.c: linkOptions is changed to set *,
6210 added if/endif conditional macros to remove options help
6211 messages from optionsTable when a port is not configured, added
6212 support for the PIc16 port in the ports table, when executing
6213 the compiler with no port specified on command line, a default
6214 port is selected with the new macro DEFAULT_PORT which is
6215 defined in port.h, in setDefaultOptions() linkOptions is removed
6216 from initialization assignment, since now it is a set,
6217 parseCmdLine uses setParseWithComma for linkOptions, in
6218 linkEdit() linkOptions are accessed with new function indexSet()
6219 which returns the i'th item of a set variable. See SDCCset.c, in
6220 linkEdit() when calling buildCmdLine(), added linkOptions as
6221 last argument. Now users can pass arguments to gplink via the
6222 -Wl option, main() uses pic16glue() to glue up pic16 programs
6223 * src/SDCCpeeph.c: various changes to support pic16

6234 * src/pic16/glue.c: commented out some error producing lines
6235 * src/pic16/main.c: __config directives are commented out to stop
6236 gpasm complaining and test the linkage with gplink, _linkCmd and
6237 _asmCmd changed to be more gplink and gpasm friendly
6238 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6239 produced an error when parsed, peep rule 12 is added to utilize
6240 movff, but it is commented out since the pCode does not support
6241 yet a command with 2 address arguments
6243 2003-05-18 <johan AT balder>
6245 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6246 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6247 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

6265 on entry now. Add tbreak. Other enhancements and fixes for use
6268 2003-05-12 Borut Razem <borut.razem AT siol.net>
6270 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6272 2003-05-11 Borut Razem <borut.razem AT siol.net>
6274 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6275 the path of bin directory, so that PATH is the only env. variable, which has to be set
6276 in case of standard installation.
6277 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7306 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7308 * in \sdcc\as\mcs51\ changed these files in order to create an
7309 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7310 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7311 following files to include the previous two files: aslink.dsp,
7312 Makefile.aslink, Makefile.bcc, and Makefile.in.
7314 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7315 .adb instead of .cdb
7317 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7319 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7320 value from option --iram-size.
7322 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7324 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7327 2002-09-18 <wiml AT hhhh.org>
7329 * SDCClrange.h: exposed setFromRange() and setToRange()
7330 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7331 packRegsForAccUse() (bug 542397)
7332 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7333 multiple times and emitting the fetch operations more than once
7334 added aopGetUsesAcc() function to allow binary operators to
7335 fetch their operands in the correct order; made genMinus() emit
7336 compact code for X = LITERAL - Y
7338 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7339 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7340 sprintf() in line 1267.
7342 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7343 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7346 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7347 Changes to aslink (All the changes are marked with 'JCF'):
7349 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7352 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7353 area BSEG. Also moves, if possible, the DATA area down into the internal
7354 ram so more space is available.
7356 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7359 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7360 not bytes. Function summary() which creates a memory usage summary
7361 file with extension .mem. Reports of overlaping stack and small stack
7362 size. If the space for the stack is less than 16 bytes aslink trows a
7365 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7366 the 8051. Option 'y' for memory summary output file.
7368 Changes to sdcc (All the changes are marked with 'JCF'):
7370 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7372 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7373 overlaying area for it (uses RegBankUsed[4]).
7375 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7376 bank zero as used by default. By default aslink locates the stack
7377 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7378 the creation of the .mem file. Delegates the allocation of data area
7379 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7380 the begining of the stack area to aslink.
7382 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7383 glue() in SDCCglue.c creates an area for it.
7385 2002-09-03 Borut Razem <borut.razem AT siol.net>
7386 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7387 sdcc/src/pic/glue.c:
7388 introduced atexit() handler for teporay files removal in case of
7389 errors, assertions, ...
7391 2002-08-29 Borut Razem <borut.razem AT siol.net>
7392 * sdcc/support/cpp2/auto-host_vc_in.h:
7393 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7394 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7395 Maybe there is a similar problem with BORLANDC? It should be checked!
7397 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7398 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7399 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7400 was not executed, and the compiler (cl) launched a warning:
7401 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7403 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7404 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7406 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7415 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7416 - added Release configuration in VS projects
7417 - review of compiler an linker options
7418 - VC .exe files are generated in bin_vc directory, not to interfere
7419 with binaries generated from other projects (cygwin, mingw, bcc ...)
7421 * sdcc/src/yacc.dsp: added
7423 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7424 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7425 and insert the version number definitions from .version
7427 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7429 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7433 removed from CVS, generated automatically
7435 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7436 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7438 2002-08-11 Borut Razem <borut.razem AT siol.net>
7439 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7441 2002-08-10 Borut Razem <borut.razem AT siol.net>
7442 * src/SDCCmain.c (main):
7443 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7444 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7445 The consequence was that some temporary files were not removed.
7448 unification of code in functions tempfilename() and tempfile():
7449 function tempnam() is defined in Visual Studio 6.0 and .NET
7451 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7453 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7454 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7455 - removed compiler command line option /WX: Treats all warnings as errors
7456 - update a list of source files, included into the project
7458 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7459 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7460 changed project type to Generic Project so that can be correcly converted to VS.NET project
7462 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7464 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7468 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7469 added return 0 statements after assert() to make compiler happy
7471 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7472 added newline in the def file to keep MSC compiler satisfied
7474 * sdcc/src/z80/gen.c:
7475 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7476 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7477 - solved MSC error in function aopDump()
7479 * sdcc_vc.h: define PREFIX as "\\sdcc"
7481 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7533 Initialized the new field char *Processor field to NULL in all ports
7536 Compiler generated registers for interrupt context saving
7537 were not getting allocated.
7539 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7542 Fixed left shift. Will promote the left side of a left shift
7543 if a) left shifting more than size of operand or b) when assigned
7544 to something size > size of left side
7546 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7656 * sdcc/src/SDCCloop.c:
7657 Previous fix was not good. basic blocks that have "break" or "return" are
7658 not really partof a loop , but live ranges used in these blocks should
7659 be live thru the entire loop, so set partOfLoop but don't add them to
7662 2002-02-21 <johan AT FRIJA>
