184 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
186 * device/lib/printf_large.c: removed inline assembly for portability and
187 readability. Use printf_fast if speed or size are more important.
188 * src/pic16/gen.c: removed conditions around use of DEBUGpc
189 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
191 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
193 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
194 prevent compiler warning
196 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
198 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
199 moved to level 0 and declared as static. Also they are explicit
200 placed in access bank. This was necessery because some times they
201 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
202 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
203 optimizations. Currently only compare to unsigned char is implemented,
204 * src/pic16/gen.c: added fReturnIdx array,
205 * (struct resolvedIfx) is moved to gen.h and made public,
206 * (struct _G): added sregsAlloc and sregsAllocSet fields,
207 * (aopForSym): added an optimization to directly store in stack of
208 the operand of a SEND iCode,
209 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
210 but as registers instead (AOP_REG) using the fReturnIdx array,
211 * (pic16_freeAsmop): remove the freed register from the
213 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
215 * (pic16_popGetTempRegCond): changed function prototype, now
216 function takes also a bitVector argument v which holds the current
217 set of registers that are allocated for stack access by aopForSym,
218 registers allocated in aopForSym for accessing stack symbols are not
219 any more part of the functions usedRegs field,
220 * (genCall): some times aopOp is called for a stack variable to be
221 send, aopForSym might perform the push, if this is true make sure
222 that genCall doesn't push the variable twice by testing _G.resDirect,
223 * (genFunction): changed testing for unspecified interrupt number
224 from 256 to INTNO_UNSPEC,
225 * modified selection scheme of frame pointer generation. Previously
226 if function did use local registers a frame pointer was generated,
227 now a frame pointer is generated only if function has arguments
228 (that need PLUSW2 register access), or has stack arguments, or the
229 compiler is not instructed to omit the frame pointer,
230 * (genEndFunction): before restoring local registers that were saved
231 in the function preamble, also restore the registers that *might*
232 have been allocated for stack access,
233 * (genRet): removed some old comments,
234 * (genCmp, the active (RN's) version): added a call to the
235 pic16_genCmp_special function to perform the compare with a more
236 robust and optimized way,
237 * (genInline): a feature has been added in inline code generation,
238 which allows a wildcard variable substitution when writing inline
239 assembly. Code is incomplete and experimental therefore undocumented,
240 * (genCast): changed order of aopOp for result and right to allow
241 aopForSym to directly load the result if possible,
242 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
243 perform an optimized compare on some selected special occasions,
244 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
245 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
246 generate an IVT any more,
247 * src/pic16/main.c (pic16_optionsTable): added command line option
249 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
250 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
252 * src/pic16/NOTES: Raphael Neider added in list of active developers
253 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
254 jumptable_end to prevent bug #,
255 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
256 inCond and outCond fields,
257 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
258 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
259 turn off register spilling,
260 * (packRegsForOneUse): synced with other ports' versions although it
261 is not used currently,
262 * (pic16_packRegisters): added an optimization while reading
263 structure bitfields, some registers may be saved (malloc code is
264 decreased by 80 bytes)
266 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
268 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
269 left is a bitfield, if yes, then don't optimize assignment. Perhaps
270 this can be optimized more?
272 2005-03-10 Raphael Neider <rneider AT web.de>
274 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
275 genNearPointerGet): (hopefully) fixed access to bitfields via
276 pointers (p->bitN = x; and x = p->bitN; failed)
278 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
280 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

465 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
466 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
467 this might fix SIGSEGVs on MinGW...
468 * src/SDCCopt.c (killDeadCode): restored original behaviour
469 (volatile operands might get thrown away though)
471 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
473 * src/pic16/gen.c: fixed bug #1106975,
474 * src/pic16/gen.c: fixed possible bug #1102572, now during TOS
475 pointer update, INTCON is saved, global interrupts are disabled and
476 restored after updateing TOS.

940 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
942 Large cummulative patch for pic16 port.
943 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
944 to call when a stack overflow occurs,
945 * (malloc.h): added CVS Id tag,
946 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
948 * added libc directory. The current version of LibC contains string
949 functions, ctype functions and macros and some functions of the
950 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
951 be extensively tested in the future. Standard disclaimer here.
952 Library is not automatically build yet. But one can build it by
953 invoking 'make' inside the libc directory.
954 * added ADC library under libio. Preliminary version yet.
956 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
957 * src/pic16/gen.c (aopForRemat): asmop size is filled by
958 aopForRemat() now and not by pic16_aopOp(),
959 * (pic16_popGetTempReg): removed warning messgae when allocating
960 temporary registers, its a buggy feature and will be removed,
961 * (pic16_popGet): set register instance field in AOP_CRY,
962 * (pic16_outBitC): fixed for results in size greater than 1,
963 * (genUminusFloat): fixed for pic16, ported code from mcs51,
964 * (pic16_storeForReturn): optimized return of 0,
965 * (genCmp): experimental code for new genCmp which uses PIC18's
966 special compare&skip instructions. Initial tests fail some times
967 with variables grater than 1 byte in size, so new code is disabled,
968 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
970 * (genCast): began a fix to optimize the casting of a bit to another
971 bit, now assigning a bitfield to another bitfield will fail, sorry,
972 * src/pic16/main.c: disabled the use of lr-support feature,
973 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
974 * added some function prototypes, added function _debugf prototype,
975 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
976 bits with offset (case PO_GPR_BIT),
977 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
979 * (isBankInstruction): modified to return 0 for no banking instruction,
980 and 1 for banking instruction,
981 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
982 caused stop processing pCodes after a inline assembly block,
983 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
984 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
985 registers when it shouldn't,
986 * src/pic16/ralloc.c (allocReg): add preliminary support for
987 supporting a limited set of temporary registers,
989 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
991 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
992 genDataPointerSet): ensure assignments always copy in MSB to LSB
994 (loadRegFromAop): recognize CLRH optimization,
995 (genFunction): optimize RECEIVE iCodes in reentrant functions
997 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
999 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1000 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1002 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3994 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3996 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3997 loaded with the linker search paths (-L arguments) and the libraries
3998 to be linked with the current source (-l arguments). Changes
3999 currently will affect only the pic16 port.
4000 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4001 include path the port specific paths and port specific libraries,
4002 * gplink command now contains the $3 argument,
4003 * src/pic16/device.h,
4004 * src/pic16/device.c,: structure PIC_device is made public and
4005 renamed to PIC16_device, the same for variable Pics which is renamed

4020 Documenting changes from previous commits.
4021 * configure.in (version 1.56),
4022 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4023 when generating output files to configure the pic16 library,
4024 but now I've commented it out, since gputils aren't installed in the
4025 SF compile farm, so library won't compile
4027 * device/lib/Makefile.in (version 1.56): initially I've added in
4028 target 'all' the prerequestive 'model-pic16' so it compiled the
4029 pic16 library, but now I've commented it out for the same reasons
4031 * added targets 'model-pic16' and 'objects-pic16' to compile the
4033 * added target 'port-specific-objects-pic16' to handle the
4034 generated libraries and copy them into the build/ directory
4035 * added target 'clean-intermediate-pic16' to clean intermediate
4036 files into pic16 directory
4037 * in target 'installdirs' added line to create directory pic16 in
4038 the installation path

4041 added lines to copy all header files to installation path,
4042 * in target 'installdirs' added line create directory for pic16
4043 headers in the installation path

4058 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4059 option so that it actually works. Made it specific to the z80, since
4060 the gbz80 doesn't have these kinds of I/O ports.
4062 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4064 * device/include/z180.h,

4088 via literal number. The symbol is placed in the corresponding
4089 position of the data ram
4090 * (pic16_dump_section): relocatable and absolute uninitialized
4091 data are now emitted in sorted order to reduce section naming,
4092 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4093 weren't marked as being in the access bank,
4095 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4097 Added portion of GNU PIC Library under the directory
4098 device/include/pic16 and device/lib/pic16. These files
4099 contain the declarations of SFRs for the PIC18Fxx2 devices.
4100 The directory is initialized via configure from toplevel.
4102 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4104 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4130 all over. Telling LaTeX to be less strict with word spacing
4131 to better keep the right margin. Changed some notes about
4132 maintainance of the ports in section 3.2.1 - is it OK like this?
4134 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4172 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4174 * src/pic16/peeph.def: all peepholes with movff are commented out,
4175 because there is a problem in the pcode peep optimizer,
4176 * src/pic16/ralloc.c: the register allocator can now reuse local

4178 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4180 Added file src/pic16/NOTES with information about program writing on
4181 the current port version.

4210 gen51Code): more efficient parameter receive for --model-large
4213 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4216 * src/z80/main.c: added missed needLinkerScript flags (more than
4217 one port structure defined in these file)
4218 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4240 * (pic14emitOverlay): modified to emit a commented overlay segment
4241 directive when no overlay data exist
4242 * (picglue): modified to emit uninitialized data segment
4243 according to udata_section_name

4253 2004-01-07 Borut Razem <borut.razem AT siol.net>
4255 * support/scripts/sdcc.nsi: update PATH
4256 * support/scripts/sdcc.ico: craeted

4263 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4265 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4267 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4269 include information about variables allocated to the overlay
4272 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4274 * as/mcs51/lkmain.c: Help about -Y option

4286 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4288 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4289 (default behaviour).
4291 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4293 A python script to validate compiler diagnostic messages. It can be
4294 used to verify that sdcc complains about bad c source code and
4295 gives a good location of the error.
4296 * support/valdiag/Makefile,
4297 * support/valdiag/valdiag.py,
4298 * support/valdiag/tests/*
4300 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4302 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4313 * src/common.h: added ifndef/define/endif macros
4314 around the header file.
4315 Bug reported from Jesus Calvino-Fraga
4317 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4319 * sdcc.spec: updated
4320 * device/include/Makefile.in: don't install CVS directories
4321 * device/lib/Makefile.in: added removal of CVS directories after install
4322 * doc/Makefile: fixed install, added local_icons
4323 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4324 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4325 * src/ds390/gen.c (genRightShift): fixed bug #870788
4326 * src/SDCCast.c (decorateType): fixed bug #870781
4328 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4330 PIC16 port related changes:
4331 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4332 added variable stackPos,
4334 * gen.c: genCall, assignResultValue: added support for
4335 pushing/retrieving function parameters to/from stack,
4336 genFunction,genEndFunction: setup stack frame for the
4338 genAddrOf: will be changed according to bug 863624
4340 * added files genutils.c and genutils.h which contain gen*
4341 debugged and optimised functions extracted from gen.c
4343 * glue.c: added variable 'externs' which holds extern symbols,
4344 pic16emitRegularMap: is modified to properly handle relocatable
4345 symbols under the new scheme,
4346 pic16createInterruptVect: is modified
4347 pic16printPublics: is modified to emit 'global' assembler directives,
4348 added pic16_printExterns to print extern symbols,
4349 pic16glue: initializes stack/frame pointer in the beginning of
4350 the assembly output. Temporary hack, will be corrected later,
4351 because gplink yet does not support stack and SDCC does not
4352 yet support a type of crt0.o object to create the final binary.
4354 * Removed many lines that contain 8051 legacy code.
4355 * The code is finally placed under a 'code' directive.
4356 * Added port specific options.
4358 * _process_pragma: simplified since now we do not need *special*
4359 include file to define SFR registers. But a separate header
4360 will be needed. This will be developed later.
4361 * _pic16_parseOptions: added, parses port specific options:
4362 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4363 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4364 --preplace-udata-with=
4366 * _pic16_setDefaultOptions: modified to initialize section names,
4367 but hack is temporarly out of order since it needs improvement.
4368 * _pic16_genAssemblerPreamble: configuration words are emitted by
4369 their address instead of their name. This part is incomplete and
4370 supports only the 18Fxx2 devices. Other devices will emit an error
4371 during assembly since they do not contain the same set of config
4373 * _pic16_genIVT: is modified,
4375 * pcode.c: added definitions for some hardware registers that are needed
4377 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4378 All PCI entries are updated. Now LFSR is supported.
4379 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4380 * added pic16_newpCodeOpLit2 to support instructions with
4381 two literal arguments
4382 * pic16_pCode2str: corrected code that emits assembler instructions
4383 with two literal operands and those that have an access bit modifier
4384 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4385 this fixes a bug which caused some labels to be lost, when an
4386 assembler directive was added, i.e. banksel,
4387 * pic16_FixRegisterBanking: improved logic that causes the insertion
4389 * InlineFunction: functions that are called once, are not any more
4390 inlined. This can be a port option in the future,
4392 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4394 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4395 hold the corresponding uninitialized symbols,
4396 * pic16_allocProcessorRegister: registers have explicit marked the
4398 * pic16_allocInternalRegister: registers are explicit marked as
4400 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4401 processing list, so bit registers were lost,
4404 * ralloc.h: added field 'accessBank' and original symbol operand
4405 in register definition,
4406 * removed the field isMapped from register definition,
4408 ** Several functions have been removed from various sources:
4409 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4410 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4411 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4412 pic16_assignRelocatableRegisters
4414 ** others have been introduced:
4415 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4416 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4418 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4420 * support/scripts/inc2h.pl: changed definition of BIT_AT
4421 to emit 'sbit at' instead of 'bit at'. This was a request.
4423 PIC16 port related preliminary changes:
4424 * gen.c: prefixed function popRegFromString with
4425 pic16_ and all references to it corrected
4426 * pcode.c: all pic16_pc_* hardware registers prefixed
4427 with underscore (_),
4428 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4429 * ralloc.c: newReg(): when register is REG_SFR then
4430 set address to rIdx,
4431 pic16_allocProcessorRegister(): marks register wasUsed=0
4432 pic16_writeUsedRegs(): added a call to assign processor
4433 registers via pic16_assignFixedRegisters
4435 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4437 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4438 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4439 variables in unused register banks. Also the SSEG is placed
4440 wherever there is enough space for it, and IDATA can be anywhere
4441 in internal RAM. For now compile using -Wl-Y[stack_size].
4442 The mem file is different for this option as well, since it
4443 makes no sense of talking about DSEG lenght.
4445 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4447 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4448 in certain cases, e.g. when ROM assignment, patch provided
4449 from Albert den Haan.
4451 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5004 not occur if the control variable is involved with a
5005 relational operator.

5494 A few small changes that speed up the peephole optimizer.
5498 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5500 Try to make the peephole optimizer smarter by maintaining
5501 an association between the assembly source code and the
5502 iCodes that originated them. Put this information to use
5503 with a new peephole rule condition "notVolatile" so that
5504 the rules can be aggressive yet still safe.

5521 Changed the type of the result of the ! (NOT) operator to char;
5522 previously it returned the same type as the source. This allows
5523 us to eliminate all the genFloatNot functions (all of its target
5524 implementations were very buggy) since !float can use the same

5536 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5537 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5538 during interrupts. Ensure WSAVE is located at a shared bank address.
5539 2. Fixed page selection in some places
5540 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5541 the registers name strings.
5542 4. Fixed "signed / unsigned compare" compiler warnings.
5543 5. The PIC port manages its own allocation of the general purpose
5544 registers, but makes no attempt to reuse them. As a result when
5545 compiling it soon runs out of general purpose registers. Some
5546 additional code was added to the files pcode.c and device.c to walk
5547 through the function call tree and rename the registers so that they
5557 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5564 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5566 Made bitfield a distinct type from bit so that bitfields
5567 convert as per ANSI C and bits retain their traditional
5568 boolean style behaviour. Implemented bitfield support in
5576 * src/ds390/gen.c: bit v bitfield split
5577 * src/z80/gen.c: New support for bitfields
5578 * support/regression/tests/bitfields.c: reenabled z80,
5581 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5583 Rules 246.x, 247.x relate to bitfields, the others speed up
5584 access to xdata mapped I/O devices.
5586 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5588 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5590 Cleaned up genPackBits and genUnpackBits and added two helper
5591 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5592 for literal assignments in genPackBits (thanks to Frieder for
5598 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5600 Fixed bug #748310 (pointer to function type mishandled when the
5601 function name is omitted). Also fixed a SIGSEGV when a function
5602 attribute (reentrant, etc) is used on a non-function or on a
5603 function but misplaced before the parameter list.

5630 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5632 Made the constant following the "interrupt" keyword optional. If
5633 omitted, the function will not automatically be given an entry
5634 in the interrupt vector table (similar to #pragma NOIV, but
5635 less syntacticly kludgy). The interrupt number is also now
5636 range checked. Also fixed a bug in the high order bit example

6112 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6113 the regression tests I'm not brave enough to enable 245.b, 245.c
6114 * doc/sdccman.lyx: added latex preamble for hyperref package.
6115 Using pdflatex this will give you a hyperlinked pdf file with

6139 * src/pic16/pcode.c: Cleaned warnings
6140 * src/pic16/pcodeflow.c: Cleaned warnings
6141 * src/pic16/pcoderegs.c: Cleaned warnings

6157 it can be defined with CFLAGS when running configure
6158 * src/SDCCmain.c: fixed compiling + linking with object files
6160 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6162 * configure.in: configure for pic16 port,
6163 added --disable-pic16-port
6164 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6165 * src/SDCCmain.c: linkOptions is changed to set *,
6166 added if/endif conditional macros to remove options help
6167 messages from optionsTable when a port is not configured, added
6168 support for the PIc16 port in the ports table, when executing
6169 the compiler with no port specified on command line, a default
6170 port is selected with the new macro DEFAULT_PORT which is
6171 defined in port.h, in setDefaultOptions() linkOptions is removed
6172 from initialization assignment, since now it is a set,
6173 parseCmdLine uses setParseWithComma for linkOptions, in
6174 linkEdit() linkOptions are accessed with new function indexSet()
6175 which returns the i'th item of a set variable. See SDCCset.c, in
6176 linkEdit() when calling buildCmdLine(), added linkOptions as
6177 last argument. Now users can pass arguments to gplink via the
6178 -Wl option, main() uses pic16glue() to glue up pic16 programs
6179 * src/SDCCpeeph.c: various changes to support pic16

6190 * src/pic16/glue.c: commented out some error producing lines
6191 * src/pic16/main.c: __config directives are commented out to stop
6192 gpasm complaining and test the linkage with gplink, _linkCmd and
6193 _asmCmd changed to be more gplink and gpasm friendly
6194 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6195 produced an error when parsed, peep rule 12 is added to utilize
6196 movff, but it is commented out since the pCode does not support
6197 yet a command with 2 address arguments
6199 2003-05-18 <johan AT balder>
6201 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6226 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6228 2003-05-11 Borut Razem <borut.razem AT siol.net>
6230 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6231 the path of bin directory, so that PATH is the only env. variable, which has to be set
6232 in case of standard installation.
6233 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7236 * src/SDCCicode.c: fixed array add
7238 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7239 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7240 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7242 2003-01-04 <johan AT balder>
7244 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7246 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7247 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7259 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7260 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7262 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7264 * in \sdcc\as\mcs51\ changed these files in order to create an
7265 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7266 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7267 following files to include the previous two files: aslink.dsp,
7268 Makefile.aslink, Makefile.bcc, and Makefile.in.
7270 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7271 .adb instead of .cdb
7273 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7275 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7276 value from option --iram-size.
7278 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7280 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7283 2002-09-18 <wiml AT hhhh.org>
7285 * SDCClrange.h: exposed setFromRange() and setToRange()
7286 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7287 packRegsForAccUse() (bug 542397)
7288 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7289 multiple times and emitting the fetch operations more than once
7290 added aopGetUsesAcc() function to allow binary operators to
7291 fetch their operands in the correct order; made genMinus() emit
7292 compact code for X = LITERAL - Y
7294 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7295 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7296 sprintf() in line 1267.
7298 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7299 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7302 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7303 Changes to aslink (All the changes are marked with 'JCF'):
7305 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7308 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7309 area BSEG. Also moves, if possible, the DATA area down into the internal
7310 ram so more space is available.
7312 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7315 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7316 not bytes. Function summary() which creates a memory usage summary
7317 file with extension .mem. Reports of overlaping stack and small stack
7318 size. If the space for the stack is less than 16 bytes aslink trows a
7321 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7322 the 8051. Option 'y' for memory summary output file.
7324 Changes to sdcc (All the changes are marked with 'JCF'):
7326 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7328 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7329 overlaying area for it (uses RegBankUsed[4]).
7331 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7332 bank zero as used by default. By default aslink locates the stack
7333 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7334 the creation of the .mem file. Delegates the allocation of data area
7335 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7336 the begining of the stack area to aslink.
7338 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7339 glue() in SDCCglue.c creates an area for it.
7341 2002-09-03 Borut Razem <borut.razem AT siol.net>
7342 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7343 sdcc/src/pic/glue.c:
7344 introduced atexit() handler for teporay files removal in case of
7345 errors, assertions, ...
7347 2002-08-29 Borut Razem <borut.razem AT siol.net>
7348 * sdcc/support/cpp2/auto-host_vc_in.h:
7349 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7350 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7351 Maybe there is a similar problem with BORLANDC? It should be checked!
7353 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7354 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7355 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7356 was not executed, and the compiler (cl) launched a warning:
7357 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7359 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7360 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7362 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7363 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7365 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7366 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

7369 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7370 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7371 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7372 - added Release configuration in VS projects
7373 - review of compiler an linker options
7374 - VC .exe files are generated in bin_vc directory, not to interfere
7375 with binaries generated from other projects (cygwin, mingw, bcc ...)
7377 * sdcc/src/yacc.dsp: added
7379 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7380 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7381 and insert the version number definitions from .version
7383 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7385 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7386 added - genarate auto-host.h using auto-host_vc_in.h as template
7389 removed from CVS, generated automatically
7391 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7392 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7394 2002-08-11 Borut Razem <borut.razem AT siol.net>
7395 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7397 2002-08-10 Borut Razem <borut.razem AT siol.net>
7398 * src/SDCCmain.c (main):
7399 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7400 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7401 The consequence was that some temporary files were not removed.
7404 unification of code in functions tempfilename() and tempfile():
7405 function tempnam() is defined in Visual Studio 6.0 and .NET
7407 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7409 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7410 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7411 - removed compiler command line option /WX: Treats all warnings as errors
7412 - update a list of source files, included into the project
7414 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7415 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
