230 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
232 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
234 * device/lib/printf_large.c: removed inline assembly for portability and
235 readability. Use printf_fast if speed or size are more important.
236 * src/pic16/gen.c: removed conditions around use of DEBUGpc
237 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
239 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
241 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
242 prevent compiler warning
244 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
246 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
247 moved to level 0 and declared as static. Also they are explicit
248 placed in access bank. This was necessery because some times they
249 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
250 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
251 optimizations. Currently only compare to unsigned char is implemented,
252 * src/pic16/gen.c: added fReturnIdx array,
253 * (struct resolvedIfx) is moved to gen.h and made public,
254 * (struct _G): added sregsAlloc and sregsAllocSet fields,
255 * (aopForSym): added an optimization to directly store in stack of
256 the operand of a SEND iCode,
257 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
258 but as registers instead (AOP_REG) using the fReturnIdx array,
259 * (pic16_freeAsmop): remove the freed register from the
261 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
263 * (pic16_popGetTempRegCond): changed function prototype, now
264 function takes also a bitVector argument v which holds the current
265 set of registers that are allocated for stack access by aopForSym,
266 registers allocated in aopForSym for accessing stack symbols are not
267 any more part of the functions usedRegs field,
268 * (genCall): some times aopOp is called for a stack variable to be
269 send, aopForSym might perform the push, if this is true make sure
270 that genCall doesn't push the variable twice by testing _G.resDirect,
271 * (genFunction): changed testing for unspecified interrupt number
272 from 256 to INTNO_UNSPEC,
273 * modified selection scheme of frame pointer generation. Previously
274 if function did use local registers a frame pointer was generated,
275 now a frame pointer is generated only if function has arguments
276 (that need PLUSW2 register access), or has stack arguments, or the
277 compiler is not instructed to omit the frame pointer,
278 * (genEndFunction): before restoring local registers that were saved
279 in the function preamble, also restore the registers that *might*
280 have been allocated for stack access,
281 * (genRet): removed some old comments,
282 * (genCmp, the active (RN's) version): added a call to the
283 pic16_genCmp_special function to perform the compare with a more
284 robust and optimized way,
285 * (genInline): a feature has been added in inline code generation,
286 which allows a wildcard variable substitution when writing inline
287 assembly. Code is incomplete and experimental therefore undocumented,
288 * (genCast): changed order of aopOp for result and right to allow
289 aopForSym to directly load the result if possible,
290 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
291 perform an optimized compare on some selected special occasions,
292 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
293 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
294 generate an IVT any more,
295 * src/pic16/main.c (pic16_optionsTable): added command line option
297 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
298 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
300 * src/pic16/NOTES: Raphael Neider added in list of active developers
301 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
302 jumptable_end to prevent bug #,
303 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
304 inCond and outCond fields,
305 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
306 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
307 turn off register spilling,
308 * (packRegsForOneUse): synced with other ports' versions although it
309 is not used currently,
310 * (pic16_packRegisters): added an optimization while reading
311 structure bitfields, some registers may be saved (malloc code is
312 decreased by 80 bytes)
314 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
316 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
317 left is a bitfield, if yes, then don't optimize assignment. Perhaps
318 this can be optimized more?
320 2005-03-10 Raphael Neider <rneider AT web.de>
322 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
323 genNearPointerGet): (hopefully) fixed access to bitfields via
324 pointers (p->bitN = x; and x = p->bitN; failed)
326 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
328 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

992 to call when a stack overflow occurs,
993 * (malloc.h): added CVS Id tag,
994 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
996 * added libc directory. The current version of LibC contains string
997 functions, ctype functions and macros and some functions of the
998 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
999 be extensively tested in the future. Standard disclaimer here.
1000 Library is not automatically build yet. But one can build it by
1001 invoking 'make' inside the libc directory.
1002 * added ADC library under libio. Preliminary version yet.

1012 * (pic16_storeForReturn): optimized return of 0,
1013 * (genCmp): experimental code for new genCmp which uses PIC18's
1014 special compare&skip instructions. Initial tests fail some times
1015 with variables grater than 1 byte in size, so new code is disabled,
1016 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1018 * (genCast): began a fix to optimize the casting of a bit to another
1019 bit, now assigning a bitfield to another bitfield will fail, sorry,

1024 bits with offset (case PO_GPR_BIT),
1025 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1027 * (isBankInstruction): modified to return 0 for no banking instruction,
1028 and 1 for banking instruction,
1029 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1030 caused stop processing pCodes after a inline assembly block,
1031 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1032 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1033 registers when it shouldn't,
1034 * src/pic16/ralloc.c (allocReg): add preliminary support for
1035 supporting a limited set of temporary registers,
1037 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1039 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1040 genDataPointerSet): ensure assignments always copy in MSB to LSB
1042 (loadRegFromAop): recognize CLRH optimization,
1043 (genFunction): optimize RECEIVE iCodes in reentrant functions
1045 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4042 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4044 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4045 loaded with the linker search paths (-L arguments) and the libraries
4046 to be linked with the current source (-l arguments). Changes
4047 currently will affect only the pic16 port.
4048 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4049 include path the port specific paths and port specific libraries,
4050 * gplink command now contains the $3 argument,
4051 * src/pic16/device.h,
4052 * src/pic16/device.c,: structure PIC_device is made public and
4053 renamed to PIC16_device, the same for variable Pics which is renamed
4054 to Pics16. Updated all references to them.
4055 * src/pic16/glue.c (pic16glue): corrected bug with code
4056 initialization which bypassed the variable initializations block.

4066 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4068 Documenting changes from previous commits.
4069 * configure.in (version 1.56),
4070 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4071 when generating output files to configure the pic16 library,
4072 but now I've commented it out, since gputils aren't installed in the
4073 SF compile farm, so library won't compile
4075 * device/lib/Makefile.in (version 1.56): initially I've added in
4076 target 'all' the prerequestive 'model-pic16' so it compiled the
4077 pic16 library, but now I've commented it out for the same reasons
4079 * added targets 'model-pic16' and 'objects-pic16' to compile the
4081 * added target 'port-specific-objects-pic16' to handle the
4082 generated libraries and copy them into the build/ directory
4083 * added target 'clean-intermediate-pic16' to clean intermediate
4084 files into pic16 directory
4085 * in target 'installdirs' added line to create directory pic16 in
4086 the installation path
4088 * device/include/Makefile.in (version 1.11): in target 'install'
4089 added lines to copy all header files to installation path,
4090 * in target 'installdirs' added line create directory for pic16
4091 headers in the installation path
4093 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

4106 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4107 option so that it actually works. Made it specific to the z80, since
4108 the gbz80 doesn't have these kinds of I/O ports.
4110 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4112 * device/include/z180.h,

4125 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4127 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4128 changed interrupt vector table generation to only emit declared vectors.
4129 * device/include/Makefile.in: added missing backslash
4130 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

4134 Mainly changes to support compilation of the device libraries
4135 * src/pic16/device.c: stack is allocated via symbol and not
4136 via literal number. The symbol is placed in the corresponding
4137 position of the data ram
4138 * (pic16_dump_section): relocatable and absolute uninitialized
4139 data are now emitted in sorted order to reduce section naming,
4140 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4141 weren't marked as being in the access bank,
4143 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4145 Added portion of GNU PIC Library under the directory
4146 device/include/pic16 and device/lib/pic16. These files
4147 contain the declarations of SFRs for the PIC18Fxx2 devices.
4148 The directory is initialized via configure from toplevel.
4150 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4152 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4153 the spilllocations to be compared correctly
4155 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4157 * src/SDCCast.c (decorateType): fixed bug introduced today
4159 2004-01-12 Borut Razem <borut.razem AT siol.net>
4161 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

4164 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4166 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4167 in simpler and even better code
4169 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
4171 * src/SDCCicode.c (operandOperation): fixed bug #874819

4175 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4177 * doc/sdccman.lyx: Moved and added some sections, small changes
4178 all over. Telling LaTeX to be less strict with word spacing
4179 to better keep the right margin. Changed some notes about
4180 maintainance of the ports in section 3.2.1 - is it OK like this?
4182 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4184 SDCC source changes:
4185 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4218 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4219 UPPER for immediate operands,
4220 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4222 * src/pic16/peeph.def: all peepholes with movff are commented out,
4223 because there is a problem in the pcode peep optimizer,
4224 * src/pic16/ralloc.c: the register allocator can now reuse local
4225 function symbols for another function. This saves register usage.
4226 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4228 Added file src/pic16/NOTES with information about program writing on
4229 the current port version.

4238 * src/SDCCmain.c : fixed #872250: -l command line defined library
4239 files are scanned before standard library files
4241 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4257 * src/mcs51/gen.c (genFunction, genEndFunction, genReceive, getTempRegs,
4258 gen51Code): more efficient parameter receive for --model-large
4261 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4264 * src/z80/main.c: added missed needLinkerScript flags (more than
4265 one port structure defined in these file)
4266 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
4269 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

4282 needLinkerScript flag
4284 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4285 * src/pic/glue.c: added variable udata_section_name to
4286 override default uninitialized data segment definition for
4287 devices only with SHAREBANK memory (reported from Erik Epetrich)
4288 * (pic14emitOverlay): modified to emit a commented overlay segment
4289 directive when no overlay data exist
4290 * (picglue): modified to emit uninitialized data segment
4291 according to udata_section_name
4292 * src/pic/main.c (_pic14_parseOptions): added command line

4296 arguments via -W option
4297 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4298 object file from '.rel' to '.o' in port->linker structure,
4299 changed size of fptr from 2 to 3 in port structure
4301 2004-01-07 Borut Razem <borut.razem AT siol.net>
4303 * support/scripts/sdcc.nsi: update PATH
4304 * support/scripts/sdcc.ico: craeted
4306 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
4308 * device/include/Makefile.in: fix install
4309 * doc/Makefile: fix install
4311 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4313 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4315 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
4316 how the function variable allocation summary is displayed; also
4317 include information about variables allocated to the overlay
4320 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4322 * as/mcs51/lkmain.c: Help about -Y option

4332 LEFT_OP (left shift)
4334 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4336 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4337 (default behaviour).
4339 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4341 A python script to validate compiler diagnostic messages. It can be
4342 used to verify that sdcc complains about bad c source code and
4343 gives a good location of the error.
4344 * support/valdiag/Makefile,
4345 * support/valdiag/valdiag.py,
4346 * support/valdiag/tests/*
4348 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4350 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
4351 * src/SDCCsymt.c (newEnumType),

4359 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4361 * src/common.h: added ifndef/define/endif macros
4362 around the header file.
4363 Bug reported from Jesus Calvino-Fraga
4365 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4367 * sdcc.spec: updated
4368 * device/include/Makefile.in: don't install CVS directories
4369 * device/lib/Makefile.in: added removal of CVS directories after install
4370 * doc/Makefile: fixed install, added local_icons
4371 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4372 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4373 * src/ds390/gen.c (genRightShift): fixed bug #870788
4374 * src/SDCCast.c (decorateType): fixed bug #870781
4376 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4378 PIC16 port related changes:
4379 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4380 added variable stackPos,
4382 * gen.c: genCall, assignResultValue: added support for
4383 pushing/retrieving function parameters to/from stack,
4384 genFunction,genEndFunction: setup stack frame for the
4386 genAddrOf: will be changed according to bug 863624
4388 * added files genutils.c and genutils.h which contain gen*
4389 debugged and optimised functions extracted from gen.c
4391 * glue.c: added variable 'externs' which holds extern symbols,
4392 pic16emitRegularMap: is modified to properly handle relocatable
4393 symbols under the new scheme,
4394 pic16createInterruptVect: is modified
4395 pic16printPublics: is modified to emit 'global' assembler directives,
4396 added pic16_printExterns to print extern symbols,
4397 pic16glue: initializes stack/frame pointer in the beginning of
4398 the assembly output. Temporary hack, will be corrected later,
4399 because gplink yet does not support stack and SDCC does not
4400 yet support a type of crt0.o object to create the final binary.
4402 * Removed many lines that contain 8051 legacy code.
4403 * The code is finally placed under a 'code' directive.
4404 * Added port specific options.
4406 * _process_pragma: simplified since now we do not need *special*
4407 include file to define SFR registers. But a separate header
4408 will be needed. This will be developed later.
4409 * _pic16_parseOptions: added, parses port specific options:
4410 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4411 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4412 --preplace-udata-with=
4414 * _pic16_setDefaultOptions: modified to initialize section names,
4415 but hack is temporarly out of order since it needs improvement.
4416 * _pic16_genAssemblerPreamble: configuration words are emitted by
4417 their address instead of their name. This part is incomplete and
4418 supports only the 18Fxx2 devices. Other devices will emit an error
4419 during assembly since they do not contain the same set of config
4421 * _pic16_genIVT: is modified,
4423 * pcode.c: added definitions for some hardware registers that are needed
4425 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4426 All PCI entries are updated. Now LFSR is supported.
4427 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4428 * added pic16_newpCodeOpLit2 to support instructions with
4429 two literal arguments
4430 * pic16_pCode2str: corrected code that emits assembler instructions
4431 with two literal operands and those that have an access bit modifier
4432 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4433 this fixes a bug which caused some labels to be lost, when an
4434 assembler directive was added, i.e. banksel,
4435 * pic16_FixRegisterBanking: improved logic that causes the insertion
4437 * InlineFunction: functions that are called once, are not any more
4438 inlined. This can be a port option in the future,
4440 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4442 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4443 hold the corresponding uninitialized symbols,
4444 * pic16_allocProcessorRegister: registers have explicit marked the
4446 * pic16_allocInternalRegister: registers are explicit marked as
4448 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4449 processing list, so bit registers were lost,
4452 * ralloc.h: added field 'accessBank' and original symbol operand
4453 in register definition,
4454 * removed the field isMapped from register definition,
4456 ** Several functions have been removed from various sources:
4457 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4458 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4459 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4460 pic16_assignRelocatableRegisters
4462 ** others have been introduced:
4463 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4464 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4466 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4468 * support/scripts/inc2h.pl: changed definition of BIT_AT
4469 to emit 'sbit at' instead of 'bit at'. This was a request.
4471 PIC16 port related preliminary changes:
4472 * gen.c: prefixed function popRegFromString with
4473 pic16_ and all references to it corrected
4474 * pcode.c: all pic16_pc_* hardware registers prefixed
4475 with underscore (_),
4476 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4477 * ralloc.c: newReg(): when register is REG_SFR then
4478 set address to rIdx,
4479 pic16_allocProcessorRegister(): marks register wasUsed=0
4480 pic16_writeUsedRegs(): added a call to assign processor
4481 registers via pic16_assignFixedRegisters
4483 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4485 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4486 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4487 variables in unused register banks. Also the SSEG is placed
4488 wherever there is enough space for it, and IDATA can be anywhere
4489 in internal RAM. For now compile using -Wl-Y[stack_size].
4490 The mem file is different for this option as well, since it
4491 makes no sense of talking about DSEG lenght.
4493 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4495 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4496 in certain cases, e.g. when ROM assignment, patch provided
4497 from Albert den Haan.
4499 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
4501 Many signedness and type propagation fixes:
4502 * src/SDCCicode.c: made geniCodeCast() static
4503 replaced SPEC_ by IS_ (cosmetic)
4504 (operandOperation): fixed div and mod operation
4505 (usualBinaryConversions): added support for promotion of char
4506 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
4507 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)
4508 (geniCodeAdd): an array index will stay unsigned, even if promoted

5505 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5506 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5507 If they pop r0/r1 they must be called in the opposite order than aopOp().
5508 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5509 (resp. --stack-auto), prepared for --xstack

5518 these ports have their own __sdcc_external_start()
5520 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5522 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5523 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5524 type for bits was changed. It resulted in bit variables becoming
5525 global, which is not permitted in PIC 14 assembly output.
5527 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5529 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5531 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5533 Z80 and MCS51 linkers complaint if a public symbol is defined

5542 A few small changes that speed up the peephole optimizer.
5546 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5548 Try to make the peephole optimizer smarter by maintaining
5549 an association between the assembly source code and the
5550 iCodes that originated them. Put this information to use
5551 with a new peephole rule condition "notVolatile" so that
5552 the rules can be aggressive yet still safe.
5557 * src/mcs51/peeph.def
5559 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5563 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5564 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5565 if the left or right operand symbols have the accuse flag set.
5567 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5569 Changed the type of the result of the ! (NOT) operator to char;
5570 previously it returned the same type as the source. This allows
5571 us to eliminate all the genFloatNot functions (all of its target
5572 implementations were very buggy) since !float can use the same
5575 * src/SDCCicode.c (ast2iCode): ! returns char

5577 * src/ds390/gen.c (genNot, genNotFloat),
5578 * src/z80/gen.c (genNot, genNotFloat),
5579 * src/pic/gen.c (genNot, genNotFloat),

5584 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5585 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5586 during interrupts. Ensure WSAVE is located at a shared bank address.
5587 2. Fixed page selection in some places
5588 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5589 the registers name strings.
5590 4. Fixed "signed / unsigned compare" compiler warnings.
5591 5. The PIC port manages its own allocation of the general purpose
5592 registers, but makes no attempt to reuse them. As a result when
5593 compiling it soon runs out of general purpose registers. Some
5594 additional code was added to the files pcode.c and device.c to walk
5595 through the function call tree and rename the registers so that they
5605 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5612 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5614 Made bitfield a distinct type from bit so that bitfields
5615 convert as per ANSI C and bits retain their traditional
5616 boolean style behaviour. Implemented bitfield support in
5624 * src/ds390/gen.c: bit v bitfield split
5625 * src/z80/gen.c: New support for bitfields
5626 * support/regression/tests/bitfields.c: reenabled z80,
5629 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5631 Rules 246.x, 247.x relate to bitfields, the others speed up
5632 access to xdata mapped I/O devices.
5634 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5636 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5638 Cleaned up genPackBits and genUnpackBits and added two helper
5639 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5640 for literal assignments in genPackBits (thanks to Frieder for
5646 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5648 Fixed bug #748310 (pointer to function type mishandled when the
5649 function name is omitted). Also fixed a SIGSEGV when a function
5650 attribute (reentrant, etc) is used on a non-function or on a
5651 function but misplaced before the parameter list.
5653 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5655 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5678 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5680 Made the constant following the "interrupt" keyword optional. If
5681 omitted, the function will not automatically be given an entry
5682 in the interrupt vector table (similar to #pragma NOIV, but
5683 less syntacticly kludgy). The interrupt number is also now
5684 range checked. Also fixed a bug in the high order bit example

5700 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5702 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5703 be re-activated by defining REDUCE_LITERALS)
5704 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5705 unsigned, but are signed by default
5706 * src/SDCCval.c (constVal): rearranged
5707 * src/SDCCval.c (valMod): preliminary fix
5708 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6160 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6161 the regression tests I'm not brave enough to enable 245.b, 245.c
6162 * doc/sdccman.lyx: added latex preamble for hyperref package.
6163 Using pdflatex this will give you a hyperlinked pdf file with
6164 bookmarks. (prepend '%' before /usepackage if this breaks something)

6178 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
6180 Applied patch from bug 737905 (renamed yylineo to mylineno):
6187 * src/pic16/pcode.c: Cleaned warnings
6188 * src/pic16/pcodeflow.c: Cleaned warnings
6189 * src/pic16/pcoderegs.c: Cleaned warnings

6202 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6204 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6205 it can be defined with CFLAGS when running configure
6206 * src/SDCCmain.c: fixed compiling + linking with object files
6208 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6210 * configure.in: configure for pic16 port,
6211 added --disable-pic16-port
6212 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6213 * src/SDCCmain.c: linkOptions is changed to set *,
6214 added if/endif conditional macros to remove options help
6215 messages from optionsTable when a port is not configured, added
6216 support for the PIc16 port in the ports table, when executing
6217 the compiler with no port specified on command line, a default
6218 port is selected with the new macro DEFAULT_PORT which is
6219 defined in port.h, in setDefaultOptions() linkOptions is removed
6220 from initialization assignment, since now it is a set,
6221 parseCmdLine uses setParseWithComma for linkOptions, in
6222 linkEdit() linkOptions are accessed with new function indexSet()
6223 which returns the i'th item of a set variable. See SDCCset.c, in
6224 linkEdit() when calling buildCmdLine(), added linkOptions as
6225 last argument. Now users can pass arguments to gplink via the
6226 -Wl option, main() uses pic16glue() to glue up pic16 programs
6227 * src/SDCCpeeph.c: various changes to support pic16

6236 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6238 * src/pic16/glue.c: commented out some error producing lines
6239 * src/pic16/main.c: __config directives are commented out to stop
6240 gpasm complaining and test the linkage with gplink, _linkCmd and
6241 _asmCmd changed to be more gplink and gpasm friendly
6242 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6243 produced an error when parsed, peep rule 12 is added to utilize
6244 movff, but it is commented out since the pCode does not support
6245 yet a command with 2 address arguments
6247 2003-05-18 <johan AT balder>
6249 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6250 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6251 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

6269 on entry now. Add tbreak. Other enhancements and fixes for use
6272 2003-05-12 Borut Razem <borut.razem AT siol.net>
6274 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6276 2003-05-11 Borut Razem <borut.razem AT siol.net>
6278 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6279 the path of bin directory, so that PATH is the only env. variable, which has to be set
6280 in case of standard installation.
6281 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7310 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7312 * in \sdcc\as\mcs51\ changed these files in order to create an
7313 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7314 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7315 following files to include the previous two files: aslink.dsp,
7316 Makefile.aslink, Makefile.bcc, and Makefile.in.
7318 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7319 .adb instead of .cdb
7321 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7323 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7324 value from option --iram-size.
7326 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7328 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7331 2002-09-18 <wiml AT hhhh.org>
7333 * SDCClrange.h: exposed setFromRange() and setToRange()
7334 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7335 packRegsForAccUse() (bug 542397)
7336 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7337 multiple times and emitting the fetch operations more than once
7338 added aopGetUsesAcc() function to allow binary operators to
7339 fetch their operands in the correct order; made genMinus() emit
7340 compact code for X = LITERAL - Y
7342 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7343 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7344 sprintf() in line 1267.
7346 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7347 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7350 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7351 Changes to aslink (All the changes are marked with 'JCF'):
7353 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7356 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7357 area BSEG. Also moves, if possible, the DATA area down into the internal
7358 ram so more space is available.
7360 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7363 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7364 not bytes. Function summary() which creates a memory usage summary
7365 file with extension .mem. Reports of overlaping stack and small stack
7366 size. If the space for the stack is less than 16 bytes aslink trows a
7369 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7370 the 8051. Option 'y' for memory summary output file.
7372 Changes to sdcc (All the changes are marked with 'JCF'):
7374 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7376 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7377 overlaying area for it (uses RegBankUsed[4]).
7379 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7380 bank zero as used by default. By default aslink locates the stack
7381 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7382 the creation of the .mem file. Delegates the allocation of data area
7383 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7384 the begining of the stack area to aslink.
7386 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7387 glue() in SDCCglue.c creates an area for it.
7389 2002-09-03 Borut Razem <borut.razem AT siol.net>
7390 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7391 sdcc/src/pic/glue.c:
7392 introduced atexit() handler for teporay files removal in case of
7393 errors, assertions, ...
7395 2002-08-29 Borut Razem <borut.razem AT siol.net>
7396 * sdcc/support/cpp2/auto-host_vc_in.h:
7397 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7398 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7399 Maybe there is a similar problem with BORLANDC? It should be checked!
7401 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7402 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7403 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7404 was not executed, and the compiler (cl) launched a warning:
7405 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7407 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7408 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7410 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

7417 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7418 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7419 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7420 - added Release configuration in VS projects
7421 - review of compiler an linker options
7422 - VC .exe files are generated in bin_vc directory, not to interfere
7423 with binaries generated from other projects (cygwin, mingw, bcc ...)
7425 * sdcc/src/yacc.dsp: added
7427 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7428 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7429 and insert the version number definitions from .version
7431 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7433 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7439 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7440 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7442 2002-08-11 Borut Razem <borut.razem AT siol.net>
7443 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7445 2002-08-10 Borut Razem <borut.razem AT siol.net>
7446 * src/SDCCmain.c (main):
7447 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7448 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7449 The consequence was that some temporary files were not removed.
7452 unification of code in functions tempfilename() and tempfile():
7453 function tempnam() is defined in Visual Studio 6.0 and .NET
7455 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7457 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7458 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7459 - removed compiler command line option /WX: Treats all warnings as errors
7460 - update a list of source files, included into the project
7462 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7463 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7464 changed project type to Generic Project so that can be correcly converted to VS.NET project
7466 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7468 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7472 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7473 added return 0 statements after assert() to make compiler happy
7475 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7476 added newline in the def file to keep MSC compiler satisfied
7478 * sdcc/src/z80/gen.c:
7479 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7480 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7481 - solved MSC error in function aopDump()
7483 * sdcc_vc.h: define PREFIX as "\\sdcc"
7485 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7537 Initialized the new field char *Processor field to NULL in all ports
7540 Compiler generated registers for interrupt context saving
7541 were not getting allocated.
7543 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7546 Fixed left shift. Will promote the left side of a left shift
7547 if a) left shifting more than size of operand or b) when assigned
7548 to something size > size of left side
7550 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7660 * sdcc/src/SDCCloop.c:
7661 Previous fix was not good. basic blocks that have "break" or "return" are
7662 not really partof a loop , but live ranges used in these blocks should
7663 be live thru the entire loop, so set partOfLoop but don't add them to
7666 2002-02-21 <johan AT FRIJA>
