205 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
207 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
208 * src/z80/main.c (_keywords[]),
209 * src/SDCCglobal.h (struct options),

294 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
296 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
298 * device/lib/printf_large.c: removed inline assembly for portability and
299 readability. Use printf_fast if speed or size are more important.
300 * src/pic16/gen.c: removed conditions around use of DEBUGpc
301 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
303 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
305 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
306 prevent compiler warning
308 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
310 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
311 moved to level 0 and declared as static. Also they are explicit
312 placed in access bank. This was necessery because some times they
313 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
314 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
315 optimizations. Currently only compare to unsigned char is implemented,
316 * src/pic16/gen.c: added fReturnIdx array,
317 * (struct resolvedIfx) is moved to gen.h and made public,
318 * (struct _G): added sregsAlloc and sregsAllocSet fields,
319 * (aopForSym): added an optimization to directly store in stack of
320 the operand of a SEND iCode,
321 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
322 but as registers instead (AOP_REG) using the fReturnIdx array,
323 * (pic16_freeAsmop): remove the freed register from the
325 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
327 * (pic16_popGetTempRegCond): changed function prototype, now
328 function takes also a bitVector argument v which holds the current
329 set of registers that are allocated for stack access by aopForSym,
330 registers allocated in aopForSym for accessing stack symbols are not
331 any more part of the functions usedRegs field,
332 * (genCall): some times aopOp is called for a stack variable to be
333 send, aopForSym might perform the push, if this is true make sure
334 that genCall doesn't push the variable twice by testing _G.resDirect,
335 * (genFunction): changed testing for unspecified interrupt number
336 from 256 to INTNO_UNSPEC,
337 * modified selection scheme of frame pointer generation. Previously
338 if function did use local registers a frame pointer was generated,
339 now a frame pointer is generated only if function has arguments
340 (that need PLUSW2 register access), or has stack arguments, or the
341 compiler is not instructed to omit the frame pointer,
342 * (genEndFunction): before restoring local registers that were saved
343 in the function preamble, also restore the registers that *might*
344 have been allocated for stack access,
345 * (genRet): removed some old comments,
346 * (genCmp, the active (RN's) version): added a call to the
347 pic16_genCmp_special function to perform the compare with a more
348 robust and optimized way,
349 * (genInline): a feature has been added in inline code generation,
350 which allows a wildcard variable substitution when writing inline
351 assembly. Code is incomplete and experimental therefore undocumented,
352 * (genCast): changed order of aopOp for result and right to allow
353 aopForSym to directly load the result if possible,
354 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
355 perform an optimized compare on some selected special occasions,
356 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
357 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
358 generate an IVT any more,
359 * src/pic16/main.c (pic16_optionsTable): added command line option
361 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
362 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
364 * src/pic16/NOTES: Raphael Neider added in list of active developers
365 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
366 jumptable_end to prevent bug #,
367 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
368 inCond and outCond fields,
369 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
370 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
371 turn off register spilling,
372 * (packRegsForOneUse): synced with other ports' versions although it
373 is not used currently,
374 * (pic16_packRegisters): added an optimization while reading
375 structure bitfields, some registers may be saved (malloc code is
376 decreased by 80 bytes)
378 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
380 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
381 left is a bitfield, if yes, then don't optimize assignment. Perhaps
382 this can be optimized more?
384 2005-03-10 Raphael Neider <rneider AT web.de>
386 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
387 genNearPointerGet): (hopefully) fixed access to bitfields via
388 pointers (p->bitN = x; and x = p->bitN; failed)
390 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
392 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
394 2005-03-09 Raphael Neider <rneider AT web.de>

431 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
433 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
434 to keep the correct label reference count when adding/removing references
435 to labels. A peephole file using this is appended to patch #1144962.

1022 Adding support for replacing ljmps with sjmps in jumptables
1023 generated for switch statements. For now you need to set the
1024 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1025 Now 4 algorithms for mcs51 jumptable generation are used:
1026 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1027 addresses loaded pc-relative for up to 112 cases and stack-pushing
1028 target addresses loaded with offset from dptr for up to 256 cases.

1058 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1060 * added libc directory. The current version of LibC contains string
1061 functions, ctype functions and macros and some functions of the
1062 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1063 be extensively tested in the future. Standard disclaimer here.
1064 Library is not automatically build yet. But one can build it by
1065 invoking 'make' inside the libc directory.

1076 * (pic16_storeForReturn): optimized return of 0,
1077 * (genCmp): experimental code for new genCmp which uses PIC18's
1078 special compare&skip instructions. Initial tests fail some times
1079 with variables grater than 1 byte in size, so new code is disabled,
1080 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1082 * (genCast): began a fix to optimize the casting of a bit to another
1083 bit, now assigning a bitfield to another bitfield will fail, sorry,

1094 caused stop processing pCodes after a inline assembly block,
1095 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1097 registers when it shouldn't,
1098 * src/pic16/ralloc.c (allocReg): add preliminary support for
1099 supporting a limited set of temporary registers,
1101 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1103 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1104 genDataPointerSet): ensure assignments always copy in MSB to LSB
1106 (loadRegFromAop): recognize CLRH optimization,
1107 (genFunction): optimize RECEIVE iCodes in reentrant functions
1109 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3989 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3991 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
3992 virus/worm forged address usage.
3994 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
3996 Fixed promotion, it should be done on AST level:
3997 * src/SDCCast.c (addCast): added promotion to int
3998 (decorateType): updated call to upCast()
3999 * src/SDCCicode.c (geniCodeLeftShift): removed call to
4000 usualUnaryConversions()
4002 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
4004 * support/regression/tests/literalop.c (mulWrapper): Added a
4005 wrapper to remove integer overflow warnings.

4009 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
4012 * support/regression/generate-cases.py (main): Changed from inline
4015 * doc/Makefile (install): Changed to depth first to get rid of
4016 missing directory install warning.
4018 * as/Makefile (install-doc): Made work on Mac.
4020 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4022 * src/SDCCast.c: added an additional type flow in decorateType() of
4023 opposite direction, see feature request #860006; it's enabled at runtime
4024 by setting the environment variable SDCC_NEWTYPEFLOW
4025 * src/SDCCast.h: changed prototype of decorateType()
4026 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4027 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4028 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4029 see feature request #877103
4030 * src/SDCCval.c: updated call of decorateType()
4031 (valBitwise): fixed bug #882876
4032 (valMinus): added promotion
4033 (valLogicAndOr): result is unsigned
4034 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4035 * src/SDCCsymt.c (computeType),
4036 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4037 must not cause an unsigned operation

4058 * src/pic/ralloc.h: applied patch from Slade Rich;
4059 added support for multiple code pages and multiple RAM banks on the
4060 PIC 14 port. The ASM files now no longer simply assume all the
4061 code / RAM are in the same page / bank. This means the linker can
4062 safely allocate code/RAM of separate ASM files to different pages/banks.
4063 * doc/sdccman.lyx: added Slade's tips
4064 * src/mcs51/peeph.def: fixed bug #880768

4076 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4077 strtof is not part of C89 and isn't included with Mac OS X.
4079 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4081 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4106 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4108 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4109 loaded with the linker search paths (-L arguments) and the libraries
4110 to be linked with the current source (-l arguments). Changes
4111 currently will affect only the pic16 port.
4112 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4113 include path the port specific paths and port specific libraries,
4114 * gplink command now contains the $3 argument,
4115 * src/pic16/device.h,
4116 * src/pic16/device.c,: structure PIC_device is made public and
4117 renamed to PIC16_device, the same for variable Pics which is renamed

4132 Documenting changes from previous commits.
4133 * configure.in (version 1.56),
4134 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4135 when generating output files to configure the pic16 library,
4136 but now I've commented it out, since gputils aren't installed in the
4137 SF compile farm, so library won't compile
4139 * device/lib/Makefile.in (version 1.56): initially I've added in
4140 target 'all' the prerequestive 'model-pic16' so it compiled the
4141 pic16 library, but now I've commented it out for the same reasons
4143 * added targets 'model-pic16' and 'objects-pic16' to compile the
4145 * added target 'port-specific-objects-pic16' to handle the
4146 generated libraries and copy them into the build/ directory
4147 * added target 'clean-intermediate-pic16' to clean intermediate
4148 files into pic16 directory
4149 * in target 'installdirs' added line to create directory pic16 in
4150 the installation path
4152 * device/include/Makefile.in (version 1.11): in target 'install'
4153 added lines to copy all header files to installation path,
4154 * in target 'installdirs' added line create directory for pic16
4155 headers in the installation path

4170 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4171 option so that it actually works. Made it specific to the z80, since
4172 the gbz80 doesn't have these kinds of I/O ports.
4174 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4176 * device/include/z180.h,

4198 Mainly changes to support compilation of the device libraries
4199 * src/pic16/device.c: stack is allocated via symbol and not
4200 via literal number. The symbol is placed in the corresponding
4201 position of the data ram
4202 * (pic16_dump_section): relocatable and absolute uninitialized
4203 data are now emitted in sorted order to reduce section naming,
4204 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4205 weren't marked as being in the access bank,
4207 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4209 Added portion of GNU PIC Library under the directory
4210 device/include/pic16 and device/lib/pic16. These files
4211 contain the declarations of SFRs for the PIC18Fxx2 devices.
4212 The directory is initialized via configure from toplevel.
4214 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4216 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4228 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4230 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
4231 in simpler and even better code

4242 all over. Telling LaTeX to be less strict with word spacing
4243 to better keep the right margin. Changed some notes about
4244 maintainance of the ports in section 3.2.1 - is it OK like this?
4246 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4286 * src/pic16/peeph.def: all peepholes with movff are commented out,
4287 because there is a problem in the pcode peep optimizer,
4288 * src/pic16/ralloc.c: the register allocator can now reuse local

4353 directive when no overlay data exist
4354 * (picglue): modified to emit uninitialized data segment
4355 according to udata_section_name

4427 Bug reported from Jesus Calvino-Fraga
4429 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4431 * sdcc.spec: updated
4432 * device/include/Makefile.in: don't install CVS directories

4440 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4442 PIC16 port related changes:
4443 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4444 added variable stackPos,
4446 * gen.c: genCall, assignResultValue: added support for
4447 pushing/retrieving function parameters to/from stack,
4448 genFunction,genEndFunction: setup stack frame for the
4450 genAddrOf: will be changed according to bug 863624
4452 * added files genutils.c and genutils.h which contain gen*
4453 debugged and optimised functions extracted from gen.c
4455 * glue.c: added variable 'externs' which holds extern symbols,
4456 pic16emitRegularMap: is modified to properly handle relocatable
4457 symbols under the new scheme,
4458 pic16createInterruptVect: is modified
4459 pic16printPublics: is modified to emit 'global' assembler directives,
4460 added pic16_printExterns to print extern symbols,
4461 pic16glue: initializes stack/frame pointer in the beginning of
4462 the assembly output. Temporary hack, will be corrected later,
4463 because gplink yet does not support stack and SDCC does not
4464 yet support a type of crt0.o object to create the final binary.
4466 * Removed many lines that contain 8051 legacy code.
4467 * The code is finally placed under a 'code' directive.
4468 * Added port specific options.
4470 * _process_pragma: simplified since now we do not need *special*
4471 include file to define SFR registers. But a separate header
4472 will be needed. This will be developed later.
4473 * _pic16_parseOptions: added, parses port specific options:
4474 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4475 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4476 --preplace-udata-with=
4478 * _pic16_setDefaultOptions: modified to initialize section names,
4479 but hack is temporarly out of order since it needs improvement.
4480 * _pic16_genAssemblerPreamble: configuration words are emitted by
4481 their address instead of their name. This part is incomplete and
4482 supports only the 18Fxx2 devices. Other devices will emit an error
4483 during assembly since they do not contain the same set of config
4485 * _pic16_genIVT: is modified,
4487 * pcode.c: added definitions for some hardware registers that are needed
4489 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4490 All PCI entries are updated. Now LFSR is supported.
4491 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4492 * added pic16_newpCodeOpLit2 to support instructions with
4493 two literal arguments
4494 * pic16_pCode2str: corrected code that emits assembler instructions
4495 with two literal operands and those that have an access bit modifier
4496 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4497 this fixes a bug which caused some labels to be lost, when an
4498 assembler directive was added, i.e. banksel,
4499 * pic16_FixRegisterBanking: improved logic that causes the insertion
4501 * InlineFunction: functions that are called once, are not any more
4502 inlined. This can be a port option in the future,
4504 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4506 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4507 hold the corresponding uninitialized symbols,
4508 * pic16_allocProcessorRegister: registers have explicit marked the
4510 * pic16_allocInternalRegister: registers are explicit marked as
4512 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4513 processing list, so bit registers were lost,
4516 * ralloc.h: added field 'accessBank' and original symbol operand
4517 in register definition,
4518 * removed the field isMapped from register definition,
4520 ** Several functions have been removed from various sources:
4521 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4522 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4523 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4524 pic16_assignRelocatableRegisters
4526 ** others have been introduced:
4527 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4528 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4530 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4532 * support/scripts/inc2h.pl: changed definition of BIT_AT
4533 to emit 'sbit at' instead of 'bit at'. This was a request.
4535 PIC16 port related preliminary changes:
4536 * gen.c: prefixed function popRegFromString with
4537 pic16_ and all references to it corrected
4538 * pcode.c: all pic16_pc_* hardware registers prefixed
4539 with underscore (_),
4540 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4541 * ralloc.c: newReg(): when register is REG_SFR then
4542 set address to rIdx,
4543 pic16_allocProcessorRegister(): marks register wasUsed=0
4544 pic16_writeUsedRegs(): added a call to assign processor
4545 registers via pic16_assignFixedRegisters
4547 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4549 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4550 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4551 variables in unused register banks. Also the SSEG is placed
4552 wherever there is enough space for it, and IDATA can be anywhere
4553 in internal RAM. For now compile using -Wl-Y[stack_size].
4554 The mem file is different for this option as well, since it
4555 makes no sense of talking about DSEG lenght.
4557 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4559 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4804 * src/SDCCast.c (decorateType): disabled a transformation I added in
4805 revision 1.188 (access to fields of a structure at an absolute address);
4806 it breaks with bitfields, extern declarations, and gcse analysis.
4807 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4808 could be assigned through a pointer, so don't complain.

4916 xdata initialization slightly shorter
4918 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5565 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5566 fetching of the pointer
5567 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5568 copied from genNearPointerSet()
5569 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5570 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5586 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5587 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5588 type for bits was changed. It resulted in bit variables becoming
5589 global, which is not permitted in PIC 14 assembly output.
5591 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5593 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5606 A few small changes that speed up the peephole optimizer.
5610 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5612 Try to make the peephole optimizer smarter by maintaining
5613 an association between the assembly source code and the
5614 iCodes that originated them. Put this information to use
5615 with a new peephole rule condition "notVolatile" so that
5616 the rules can be aggressive yet still safe.
5621 * src/mcs51/peeph.def
5623 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5627 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5628 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5629 if the left or right operand symbols have the accuse flag set.
5631 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5633 Changed the type of the result of the ! (NOT) operator to char;
5634 previously it returned the same type as the source. This allows
5635 us to eliminate all the genFloatNot functions (all of its target
5636 implementations were very buggy) since !float can use the same

5648 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5649 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5650 during interrupts. Ensure WSAVE is located at a shared bank address.
5651 2. Fixed page selection in some places
5652 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5653 the registers name strings.
5654 4. Fixed "signed / unsigned compare" compiler warnings.
5655 5. The PIC port manages its own allocation of the general purpose
5656 registers, but makes no attempt to reuse them. As a result when
5657 compiling it soon runs out of general purpose registers. Some
5658 additional code was added to the files pcode.c and device.c to walk
5659 through the function call tree and rename the registers so that they
5669 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5676 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5678 Made bitfield a distinct type from bit so that bitfields
5679 convert as per ANSI C and bits retain their traditional
5680 boolean style behaviour. Implemented bitfield support in
5688 * src/ds390/gen.c: bit v bitfield split
5689 * src/z80/gen.c: New support for bitfields
5690 * support/regression/tests/bitfields.c: reenabled z80,
5693 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5695 Rules 246.x, 247.x relate to bitfields, the others speed up
5696 access to xdata mapped I/O devices.
5698 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5700 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5702 Cleaned up genPackBits and genUnpackBits and added two helper
5703 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5704 for literal assignments in genPackBits (thanks to Frieder for
5710 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5712 Fixed bug #748310 (pointer to function type mishandled when the
5713 function name is omitted). Also fixed a SIGSEGV when a function
5714 attribute (reentrant, etc) is used on a non-function or on a
5715 function but misplaced before the parameter list.
5717 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5719 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5742 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5744 Made the constant following the "interrupt" keyword optional. If
5745 omitted, the function will not automatically be given an entry
5746 in the interrupt vector table (similar to #pragma NOIV, but
5747 less syntacticly kludgy). The interrupt number is also now
5748 range checked. Also fixed a bug in the high order bit example

5762 * src/SDCCicode.c (operandOperation): rewritten some ops
5763 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5764 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5766 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5767 be re-activated by defining REDUCE_LITERALS)
5768 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5769 unsigned, but are signed by default
5770 * src/SDCCval.c (constVal): rearranged
5771 * src/SDCCval.c (valMod): preliminary fix
5772 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5815 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5816 * src/SDCCval.c (valDiv, valMod): fixed signdness
5817 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5818 signedness of modulo, left and right shift

6269 it can be defined with CFLAGS when running configure
6270 * src/SDCCmain.c: fixed compiling + linking with object files
6272 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6275 added --disable-pic16-port
6276 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6277 * src/SDCCmain.c: linkOptions is changed to set *,
6278 added if/endif conditional macros to remove options help
6279 messages from optionsTable when a port is not configured, added
6280 support for the PIc16 port in the ports table, when executing
6281 the compiler with no port specified on command line, a default
6282 port is selected with the new macro DEFAULT_PORT which is
6283 defined in port.h, in setDefaultOptions() linkOptions is removed
6284 from initialization assignment, since now it is a set,
6285 parseCmdLine uses setParseWithComma for linkOptions, in
6286 linkEdit() linkOptions are accessed with new function indexSet()
6287 which returns the i'th item of a set variable. See SDCCset.c, in
6288 linkEdit() when calling buildCmdLine(), added linkOptions as
6289 last argument. Now users can pass arguments to gplink via the
6290 -Wl option, main() uses pic16glue() to glue up pic16 programs

6302 * src/pic16/glue.c: commented out some error producing lines
6303 * src/pic16/main.c: __config directives are commented out to stop
6304 gpasm complaining and test the linkage with gplink, _linkCmd and
6305 _asmCmd changed to be more gplink and gpasm friendly
6306 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6307 produced an error when parsed, peep rule 12 is added to utilize
6308 movff, but it is commented out since the pCode does not support
6309 yet a command with 2 address arguments
6311 2003-05-18 <johan AT balder>
6313 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6314 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6340 2003-05-11 Borut Razem <borut.razem AT siol.net>
6342 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6343 the path of bin directory, so that PATH is the only env. variable, which has to be set
6344 in case of standard installation.
6345 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7402 added aopGetUsesAcc() function to allow binary operators to
7403 fetch their operands in the correct order; made genMinus() emit
7404 compact code for X = LITERAL - Y
7406 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7407 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7408 sprintf() in line 1267.
7410 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7411 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7414 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7415 Changes to aslink (All the changes are marked with 'JCF'):
7417 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7420 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7421 area BSEG. Also moves, if possible, the DATA area down into the internal
7422 ram so more space is available.
7424 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7427 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7428 not bytes. Function summary() which creates a memory usage summary
7429 file with extension .mem. Reports of overlaping stack and small stack
7430 size. If the space for the stack is less than 16 bytes aslink trows a
7433 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7434 the 8051. Option 'y' for memory summary output file.
7436 Changes to sdcc (All the changes are marked with 'JCF'):
7438 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7440 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7441 overlaying area for it (uses RegBankUsed[4]).
7443 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7444 bank zero as used by default. By default aslink locates the stack
7445 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7446 the creation of the .mem file. Delegates the allocation of data area
7447 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7448 the begining of the stack area to aslink.
7450 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7451 glue() in SDCCglue.c creates an area for it.
7453 2002-09-03 Borut Razem <borut.razem AT siol.net>
7454 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7455 sdcc/src/pic/glue.c:
7456 introduced atexit() handler for teporay files removal in case of
7457 errors, assertions, ...
7459 2002-08-29 Borut Razem <borut.razem AT siol.net>
7460 * sdcc/support/cpp2/auto-host_vc_in.h:
7461 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7462 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7463 Maybe there is a similar problem with BORLANDC? It should be checked!
7465 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7466 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7467 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7468 was not executed, and the compiler (cl) launched a warning:
7469 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7471 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7472 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7474 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7475 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7477 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7478 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7479 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7480 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7481 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7482 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7483 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7484 - added Release configuration in VS projects
7485 - review of compiler an linker options
7486 - VC .exe files are generated in bin_vc directory, not to interfere
7487 with binaries generated from other projects (cygwin, mingw, bcc ...)
7489 * sdcc/src/yacc.dsp: added
7491 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7492 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7493 and insert the version number definitions from .version
7495 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7497 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7498 added - genarate auto-host.h using auto-host_vc_in.h as template
7501 removed from CVS, generated automatically
7503 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7504 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7506 2002-08-11 Borut Razem <borut.razem AT siol.net>
7507 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7509 2002-08-10 Borut Razem <borut.razem AT siol.net>
7510 * src/SDCCmain.c (main):
7511 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7512 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7513 The consequence was that some temporary files were not removed.
7516 unification of code in functions tempfilename() and tempfile():
7517 function tempnam() is defined in Visual Studio 6.0 and .NET
7519 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7521 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7522 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7523 - removed compiler command line option /WX: Treats all warnings as errors
7524 - update a list of source files, included into the project
7526 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7527 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7528 changed project type to Generic Project so that can be correcly converted to VS.NET project
7530 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7532 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7534 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7536 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7537 added return 0 statements after assert() to make compiler happy
7539 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7540 added newline in the def file to keep MSC compiler satisfied
7542 * sdcc/src/z80/gen.c:
7543 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7544 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7545 - solved MSC error in function aopDump()
7547 * sdcc_vc.h: define PREFIX as "\\sdcc"
7549 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7550 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7589 2002-03-28 Johan Knol <johan AT balder>
7591 * src/SDCCval.c: fixed bug #532436
7593 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7595 Added "char *Processor" field to the port structure.
7598 Added -p option. Allows port dependent processor to be specified.
7601 Initialized the new field char *Processor field to NULL in all ports
7604 Compiler generated registers for interrupt context saving
7605 were not getting allocated.
7607 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7610 Fixed left shift. Will promote the left side of a left shift
7611 if a) left shifting more than size of operand or b) when assigned
7612 to something size > size of left side
7614 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7616 tons of changes. Register allocation has been
7617 rewritten. Added customization for the various PICs. Flow

7722 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7724 * sdcc/src/SDCCloop.c:
7725 Previous fix was not good. basic blocks that have "break" or "return" are
7726 not really partof a loop , but live ranges used in these blocks should
7727 be live thru the entire loop, so set partOfLoop but don't add them to
7730 2002-02-21 <johan AT FRIJA>
7732 * src/SDCCcse.c: fixed bug #514308
7734 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7737 Fixed BUG #519583. If a conditional block ended in a return/break
7738 statement inside a loop, it was not being considered part of the loop.
7740 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7742 2002-02-10 Karl Bongers <karl AT turbobit.com>
7745 Fixed up SDCDB debugger somewhat. Updated debugger/README
7746 with lots of comments and notes.
7748 * device/examples/test2.c:
7749 Fix bug, "red" variable not being initialized(compiler complained).
