201 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
203 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
204 * src/z80/main.c (_keywords[]),
205 * src/SDCCglobal.h (struct options),

292 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
294 * device/lib/printf_large.c: removed inline assembly for portability and
295 readability. Use printf_fast if speed or size are more important.
296 * src/pic16/gen.c: removed conditions around use of DEBUGpc
297 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
299 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
301 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
302 prevent compiler warning
304 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
306 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
307 moved to level 0 and declared as static. Also they are explicit
308 placed in access bank. This was necessery because some times they
309 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
310 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
311 optimizations. Currently only compare to unsigned char is implemented,
312 * src/pic16/gen.c: added fReturnIdx array,
313 * (struct resolvedIfx) is moved to gen.h and made public,
314 * (struct _G): added sregsAlloc and sregsAllocSet fields,
315 * (aopForSym): added an optimization to directly store in stack of
316 the operand of a SEND iCode,
317 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
318 but as registers instead (AOP_REG) using the fReturnIdx array,
319 * (pic16_freeAsmop): remove the freed register from the
321 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
323 * (pic16_popGetTempRegCond): changed function prototype, now
324 function takes also a bitVector argument v which holds the current
325 set of registers that are allocated for stack access by aopForSym,
326 registers allocated in aopForSym for accessing stack symbols are not
327 any more part of the functions usedRegs field,
328 * (genCall): some times aopOp is called for a stack variable to be
329 send, aopForSym might perform the push, if this is true make sure
330 that genCall doesn't push the variable twice by testing _G.resDirect,
331 * (genFunction): changed testing for unspecified interrupt number
332 from 256 to INTNO_UNSPEC,
333 * modified selection scheme of frame pointer generation. Previously
334 if function did use local registers a frame pointer was generated,
335 now a frame pointer is generated only if function has arguments
336 (that need PLUSW2 register access), or has stack arguments, or the
337 compiler is not instructed to omit the frame pointer,
338 * (genEndFunction): before restoring local registers that were saved
339 in the function preamble, also restore the registers that *might*
340 have been allocated for stack access,
341 * (genRet): removed some old comments,
342 * (genCmp, the active (RN's) version): added a call to the
343 pic16_genCmp_special function to perform the compare with a more
344 robust and optimized way,
345 * (genInline): a feature has been added in inline code generation,
346 which allows a wildcard variable substitution when writing inline
347 assembly. Code is incomplete and experimental therefore undocumented,
348 * (genCast): changed order of aopOp for result and right to allow
349 aopForSym to directly load the result if possible,
350 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
351 perform an optimized compare on some selected special occasions,
352 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
353 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
354 generate an IVT any more,
355 * src/pic16/main.c (pic16_optionsTable): added command line option
357 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
358 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
360 * src/pic16/NOTES: Raphael Neider added in list of active developers
361 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
362 jumptable_end to prevent bug #,
363 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
364 inCond and outCond fields,
365 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
366 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
367 turn off register spilling,
368 * (packRegsForOneUse): synced with other ports' versions although it
369 is not used currently,
370 * (pic16_packRegisters): added an optimization while reading
371 structure bitfields, some registers may be saved (malloc code is
372 decreased by 80 bytes)
374 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
376 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
377 left is a bitfield, if yes, then don't optimize assignment. Perhaps
378 this can be optimized more?
380 2005-03-10 Raphael Neider <rneider AT web.de>
382 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
383 genNearPointerGet): (hopefully) fixed access to bitfields via
384 pointers (p->bitN = x; and x = p->bitN; failed)
386 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
388 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
390 2005-03-09 Raphael Neider <rneider AT web.de>

427 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
429 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
430 to keep the correct label reference count when adding/removing references
431 to labels. A peephole file using this is appended to patch #1144962.
433 2005-02-14 Raphael Neider <rneider AT web.de>

1018 Adding support for replacing ljmps with sjmps in jumptables
1019 generated for switch statements. For now you need to set the
1020 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1021 Now 4 algorithms for mcs51 jumptable generation are used:
1022 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1023 addresses loaded pc-relative for up to 112 cases and stack-pushing
1024 target addresses loaded with offset from dptr for up to 256 cases.

1054 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1056 * added libc directory. The current version of LibC contains string
1057 functions, ctype functions and macros and some functions of the
1058 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1059 be extensively tested in the future. Standard disclaimer here.
1060 Library is not automatically build yet. But one can build it by
1061 invoking 'make' inside the libc directory.
1062 * added ADC library under libio. Preliminary version yet.

1072 * (pic16_storeForReturn): optimized return of 0,
1073 * (genCmp): experimental code for new genCmp which uses PIC18's
1074 special compare&skip instructions. Initial tests fail some times
1075 with variables grater than 1 byte in size, so new code is disabled,
1076 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1078 * (genCast): began a fix to optimize the casting of a bit to another
1079 bit, now assigning a bitfield to another bitfield will fail, sorry,

1088 and 1 for banking instruction,
1089 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1090 caused stop processing pCodes after a inline assembly block,
1091 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1093 registers when it shouldn't,
1094 * src/pic16/ralloc.c (allocReg): add preliminary support for
1095 supporting a limited set of temporary registers,
1097 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1099 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

1103 (genFunction): optimize RECEIVE iCodes in reentrant functions
1105 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3990 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
3992 Fixed promotion, it should be done on AST level:
3993 * src/SDCCast.c (addCast): added promotion to int
3994 (decorateType): updated call to upCast()
3995 * src/SDCCicode.c (geniCodeLeftShift): removed call to
3996 usualUnaryConversions()
3998 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
4000 * support/regression/tests/literalop.c (mulWrapper): Added a
4001 wrapper to remove integer overflow warnings.

4005 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
4008 * support/regression/generate-cases.py (main): Changed from inline
4011 * doc/Makefile (install): Changed to depth first to get rid of
4012 missing directory install warning.
4014 * as/Makefile (install-doc): Made work on Mac.
4016 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4018 * src/SDCCast.c: added an additional type flow in decorateType() of
4019 opposite direction, see feature request #860006; it's enabled at runtime
4020 by setting the environment variable SDCC_NEWTYPEFLOW
4021 * src/SDCCast.h: changed prototype of decorateType()
4022 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4023 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4024 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4025 see feature request #877103
4026 * src/SDCCval.c: updated call of decorateType()
4027 (valBitwise): fixed bug #882876
4028 (valMinus): added promotion
4029 (valLogicAndOr): result is unsigned
4030 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4031 * src/SDCCsymt.c (computeType),
4032 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4033 must not cause an unsigned operation

4054 * src/pic/ralloc.h: applied patch from Slade Rich;
4055 added support for multiple code pages and multiple RAM banks on the
4056 PIC 14 port. The ASM files now no longer simply assume all the
4057 code / RAM are in the same page / bank. This means the linker can
4058 safely allocate code/RAM of separate ASM files to different pages/banks.
4059 * doc/sdccman.lyx: added Slade's tips
4060 * src/mcs51/peeph.def: fixed bug #880768

4072 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4073 strtof is not part of C89 and isn't included with Mac OS X.
4075 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4077 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4102 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4104 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4105 loaded with the linker search paths (-L arguments) and the libraries
4106 to be linked with the current source (-l arguments). Changes
4107 currently will affect only the pic16 port.
4108 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4109 include path the port specific paths and port specific libraries,
4110 * gplink command now contains the $3 argument,
4111 * src/pic16/device.h,
4112 * src/pic16/device.c,: structure PIC_device is made public and
4113 renamed to PIC16_device, the same for variable Pics which is renamed

4128 Documenting changes from previous commits.
4129 * configure.in (version 1.56),
4130 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4131 when generating output files to configure the pic16 library,
4132 but now I've commented it out, since gputils aren't installed in the
4133 SF compile farm, so library won't compile
4135 * device/lib/Makefile.in (version 1.56): initially I've added in
4136 target 'all' the prerequestive 'model-pic16' so it compiled the
4137 pic16 library, but now I've commented it out for the same reasons
4139 * added targets 'model-pic16' and 'objects-pic16' to compile the
4141 * added target 'port-specific-objects-pic16' to handle the
4142 generated libraries and copy them into the build/ directory
4143 * added target 'clean-intermediate-pic16' to clean intermediate
4144 files into pic16 directory
4145 * in target 'installdirs' added line to create directory pic16 in
4146 the installation path
4148 * device/include/Makefile.in (version 1.11): in target 'install'
4149 added lines to copy all header files to installation path,
4150 * in target 'installdirs' added line create directory for pic16
4151 headers in the installation path

4166 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4167 option so that it actually works. Made it specific to the z80, since
4168 the gbz80 doesn't have these kinds of I/O ports.
4170 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4172 * device/include/z180.h,

4194 Mainly changes to support compilation of the device libraries
4195 * src/pic16/device.c: stack is allocated via symbol and not
4196 via literal number. The symbol is placed in the corresponding
4197 position of the data ram
4198 * (pic16_dump_section): relocatable and absolute uninitialized
4199 data are now emitted in sorted order to reduce section naming,
4200 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4201 weren't marked as being in the access bank,
4203 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4205 Added portion of GNU PIC Library under the directory
4206 device/include/pic16 and device/lib/pic16. These files
4207 contain the declarations of SFRs for the PIC18Fxx2 devices.
4208 The directory is initialized via configure from toplevel.

4238 all over. Telling LaTeX to be less strict with word spacing
4239 to better keep the right margin. Changed some notes about
4240 maintainance of the ports in section 3.2.1 - is it OK like this?
4242 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4282 * src/pic16/peeph.def: all peepholes with movff are commented out,
4283 because there is a problem in the pcode peep optimizer,
4284 * src/pic16/ralloc.c: the register allocator can now reuse local

4423 Bug reported from Jesus Calvino-Fraga
4425 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4427 * sdcc.spec: updated

4436 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4438 PIC16 port related changes:
4439 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4440 added variable stackPos,
4442 * gen.c: genCall, assignResultValue: added support for
4443 pushing/retrieving function parameters to/from stack,
4444 genFunction,genEndFunction: setup stack frame for the
4446 genAddrOf: will be changed according to bug 863624
4448 * added files genutils.c and genutils.h which contain gen*
4449 debugged and optimised functions extracted from gen.c
4451 * glue.c: added variable 'externs' which holds extern symbols,
4452 pic16emitRegularMap: is modified to properly handle relocatable
4453 symbols under the new scheme,
4454 pic16createInterruptVect: is modified
4455 pic16printPublics: is modified to emit 'global' assembler directives,
4456 added pic16_printExterns to print extern symbols,
4457 pic16glue: initializes stack/frame pointer in the beginning of
4458 the assembly output. Temporary hack, will be corrected later,
4459 because gplink yet does not support stack and SDCC does not
4460 yet support a type of crt0.o object to create the final binary.
4462 * Removed many lines that contain 8051 legacy code.
4463 * The code is finally placed under a 'code' directive.
4464 * Added port specific options.
4466 * _process_pragma: simplified since now we do not need *special*
4467 include file to define SFR registers. But a separate header
4468 will be needed. This will be developed later.
4469 * _pic16_parseOptions: added, parses port specific options:
4470 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4471 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4472 --preplace-udata-with=
4474 * _pic16_setDefaultOptions: modified to initialize section names,
4475 but hack is temporarly out of order since it needs improvement.
4476 * _pic16_genAssemblerPreamble: configuration words are emitted by
4477 their address instead of their name. This part is incomplete and
4478 supports only the 18Fxx2 devices. Other devices will emit an error
4479 during assembly since they do not contain the same set of config
4481 * _pic16_genIVT: is modified,
4483 * pcode.c: added definitions for some hardware registers that are needed
4485 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4486 All PCI entries are updated. Now LFSR is supported.
4487 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4488 * added pic16_newpCodeOpLit2 to support instructions with
4489 two literal arguments
4490 * pic16_pCode2str: corrected code that emits assembler instructions
4491 with two literal operands and those that have an access bit modifier
4492 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4493 this fixes a bug which caused some labels to be lost, when an
4494 assembler directive was added, i.e. banksel,
4495 * pic16_FixRegisterBanking: improved logic that causes the insertion
4497 * InlineFunction: functions that are called once, are not any more
4498 inlined. This can be a port option in the future,
4500 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4502 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4503 hold the corresponding uninitialized symbols,
4504 * pic16_allocProcessorRegister: registers have explicit marked the
4506 * pic16_allocInternalRegister: registers are explicit marked as
4508 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4509 processing list, so bit registers were lost,
4512 * ralloc.h: added field 'accessBank' and original symbol operand
4513 in register definition,
4514 * removed the field isMapped from register definition,
4516 ** Several functions have been removed from various sources:
4517 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4518 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4519 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4520 pic16_assignRelocatableRegisters
4522 ** others have been introduced:
4523 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4524 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4526 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4528 * support/scripts/inc2h.pl: changed definition of BIT_AT
4529 to emit 'sbit at' instead of 'bit at'. This was a request.
4531 PIC16 port related preliminary changes:
4532 * gen.c: prefixed function popRegFromString with
4533 pic16_ and all references to it corrected
4534 * pcode.c: all pic16_pc_* hardware registers prefixed
4535 with underscore (_),
4536 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4537 * ralloc.c: newReg(): when register is REG_SFR then
4538 set address to rIdx,
4539 pic16_allocProcessorRegister(): marks register wasUsed=0
4540 pic16_writeUsedRegs(): added a call to assign processor
4541 registers via pic16_assignFixedRegisters
4543 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4545 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4546 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4547 variables in unused register banks. Also the SSEG is placed
4548 wherever there is enough space for it, and IDATA can be anywhere
4549 in internal RAM. For now compile using -Wl-Y[stack_size].
4550 The mem file is different for this option as well, since it
4551 makes no sense of talking about DSEG lenght.
4553 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4555 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4556 in certain cases, e.g. when ROM assignment, patch provided
4557 from Albert den Haan.

4800 * src/SDCCast.c (decorateType): disabled a transformation I added in
4801 revision 1.188 (access to fields of a structure at an absolute address);
4802 it breaks with bitfields, extern declarations, and gcse analysis.
4803 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4804 could be assigned through a pointer, so don't complain.

4912 xdata initialization slightly shorter
4914 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5563 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5564 copied from genNearPointerSet()
5565 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5566 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5582 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5583 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5584 type for bits was changed. It resulted in bit variables becoming
5585 global, which is not permitted in PIC 14 assembly output.
5587 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5602 A few small changes that speed up the peephole optimizer.
5606 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5608 Try to make the peephole optimizer smarter by maintaining
5609 an association between the assembly source code and the
5610 iCodes that originated them. Put this information to use
5611 with a new peephole rule condition "notVolatile" so that
5612 the rules can be aggressive yet still safe.
5617 * src/mcs51/peeph.def
5619 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5623 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5624 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5625 if the left or right operand symbols have the accuse flag set.
5627 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5629 Changed the type of the result of the ! (NOT) operator to char;
5630 previously it returned the same type as the source. This allows
5631 us to eliminate all the genFloatNot functions (all of its target
5632 implementations were very buggy) since !float can use the same
5635 * src/SDCCicode.c (ast2iCode): ! returns char

5644 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5645 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5646 during interrupts. Ensure WSAVE is located at a shared bank address.
5647 2. Fixed page selection in some places
5648 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5649 the registers name strings.
5650 4. Fixed "signed / unsigned compare" compiler warnings.
5651 5. The PIC port manages its own allocation of the general purpose
5652 registers, but makes no attempt to reuse them. As a result when
5653 compiling it soon runs out of general purpose registers. Some
5654 additional code was added to the files pcode.c and device.c to walk
5655 through the function call tree and rename the registers so that they
5665 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5666 genPlus() & genMinus() when the result is the same as left or right

5672 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5674 Made bitfield a distinct type from bit so that bitfields
5675 convert as per ANSI C and bits retain their traditional
5676 boolean style behaviour. Implemented bitfield support in
5684 * src/ds390/gen.c: bit v bitfield split
5685 * src/z80/gen.c: New support for bitfields
5686 * support/regression/tests/bitfields.c: reenabled z80,
5689 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5691 Rules 246.x, 247.x relate to bitfields, the others speed up
5692 access to xdata mapped I/O devices.
5694 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5696 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5698 Cleaned up genPackBits and genUnpackBits and added two helper
5699 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5700 for literal assignments in genPackBits (thanks to Frieder for
5706 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5708 Fixed bug #748310 (pointer to function type mishandled when the
5709 function name is omitted). Also fixed a SIGSEGV when a function
5710 attribute (reentrant, etc) is used on a non-function or on a
5711 function but misplaced before the parameter list.
5713 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5715 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5716 * support/Util/SDCCerr.h,
5717 * support/Util/SDCCerr.c: Added func attr misuse error msg

5738 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5740 Made the constant following the "interrupt" keyword optional. If
5741 omitted, the function will not automatically be given an entry
5742 in the interrupt vector table (similar to #pragma NOIV, but
5743 less syntacticly kludgy). The interrupt number is also now
5744 range checked. Also fixed a bug in the high order bit example
5751 * support/Util/SDCCerr.c
5752 * support/Util/SDCCerr.h
5755 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5758 * src/SDCCicode.c (operandOperation): rewritten some ops
5759 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5760 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5762 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5763 be re-activated by defining REDUCE_LITERALS)
5764 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5765 unsigned, but are signed by default
5766 * src/SDCCval.c (constVal): rearranged
5767 * src/SDCCval.c (valMod): preliminary fix
5768 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5810 constants are unsigned; added recognition of "u" flag for unsigned
5811 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5812 * src/SDCCval.c (valDiv, valMod): fixed signdness
5813 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5814 signedness of modulo, left and right shift

6220 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6221 the regression tests I'm not brave enough to enable 245.b, 245.c
6222 * doc/sdccman.lyx: added latex preamble for hyperref package.
6223 Using pdflatex this will give you a hyperlinked pdf file with
6224 bookmarks. (prepend '%' before /usepackage if this breaks something)

6271 added --disable-pic16-port
6272 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6273 * src/SDCCmain.c: linkOptions is changed to set *,
6274 added if/endif conditional macros to remove options help
6275 messages from optionsTable when a port is not configured, added
6276 support for the PIc16 port in the ports table, when executing
6277 the compiler with no port specified on command line, a default
6278 port is selected with the new macro DEFAULT_PORT which is
6279 defined in port.h, in setDefaultOptions() linkOptions is removed
6280 from initialization assignment, since now it is a set,
6281 parseCmdLine uses setParseWithComma for linkOptions, in
6282 linkEdit() linkOptions are accessed with new function indexSet()
6283 which returns the i'th item of a set variable. See SDCCset.c, in
6284 linkEdit() when calling buildCmdLine(), added linkOptions as
6285 last argument. Now users can pass arguments to gplink via the
6286 -Wl option, main() uses pic16glue() to glue up pic16 programs

6298 * src/pic16/glue.c: commented out some error producing lines
6299 * src/pic16/main.c: __config directives are commented out to stop
6300 gpasm complaining and test the linkage with gplink, _linkCmd and
6301 _asmCmd changed to be more gplink and gpasm friendly
6302 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6303 produced an error when parsed, peep rule 12 is added to utilize
6304 movff, but it is commented out since the pCode does not support
6305 yet a command with 2 address arguments
6307 2003-05-18 <johan AT balder>
6309 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6336 2003-05-11 Borut Razem <borut.razem AT siol.net>
6338 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6339 the path of bin directory, so that PATH is the only env. variable, which has to be set
6340 in case of standard installation.
6341 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7407 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7410 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7411 Changes to aslink (All the changes are marked with 'JCF'):
7413 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7416 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7417 area BSEG. Also moves, if possible, the DATA area down into the internal
7418 ram so more space is available.
7420 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7423 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7424 not bytes. Function summary() which creates a memory usage summary
7425 file with extension .mem. Reports of overlaping stack and small stack
7426 size. If the space for the stack is less than 16 bytes aslink trows a
7429 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7430 the 8051. Option 'y' for memory summary output file.
7432 Changes to sdcc (All the changes are marked with 'JCF'):
7434 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7436 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7437 overlaying area for it (uses RegBankUsed[4]).
7439 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7440 bank zero as used by default. By default aslink locates the stack
7441 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7442 the creation of the .mem file. Delegates the allocation of data area
7443 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7444 the begining of the stack area to aslink.
7446 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7447 glue() in SDCCglue.c creates an area for it.
7449 2002-09-03 Borut Razem <borut.razem AT siol.net>
7450 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7451 sdcc/src/pic/glue.c:
7452 introduced atexit() handler for teporay files removal in case of
7453 errors, assertions, ...
7455 2002-08-29 Borut Razem <borut.razem AT siol.net>
7456 * sdcc/support/cpp2/auto-host_vc_in.h:
7457 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7458 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7459 Maybe there is a similar problem with BORLANDC? It should be checked!
7461 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7462 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7463 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7464 was not executed, and the compiler (cl) launched a warning:
7465 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7467 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7468 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7470 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7471 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7473 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7474 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7475 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7476 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7477 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7478 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7479 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7480 - added Release configuration in VS projects
7481 - review of compiler an linker options
7482 - VC .exe files are generated in bin_vc directory, not to interfere
7483 with binaries generated from other projects (cygwin, mingw, bcc ...)
7485 * sdcc/src/yacc.dsp: added
7487 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7488 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7489 and insert the version number definitions from .version
7491 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7493 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7494 added - genarate auto-host.h using auto-host_vc_in.h as template
7497 removed from CVS, generated automatically
7499 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7500 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7502 2002-08-11 Borut Razem <borut.razem AT siol.net>
7503 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7505 2002-08-10 Borut Razem <borut.razem AT siol.net>
7506 * src/SDCCmain.c (main):
7507 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7508 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7509 The consequence was that some temporary files were not removed.
7512 unification of code in functions tempfilename() and tempfile():
7513 function tempnam() is defined in Visual Studio 6.0 and .NET
7515 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7517 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7518 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7519 - removed compiler command line option /WX: Treats all warnings as errors
7520 - update a list of source files, included into the project
7522 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7523 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7524 changed project type to Generic Project so that can be correcly converted to VS.NET project
7526 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7528 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7530 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7532 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7533 added return 0 statements after assert() to make compiler happy
7535 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7536 added newline in the def file to keep MSC compiler satisfied
7538 * sdcc/src/z80/gen.c:
7539 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7540 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7541 - solved MSC error in function aopDump()
7543 * sdcc_vc.h: define PREFIX as "\\sdcc"
7545 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7546 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7594 Added -p option. Allows port dependent processor to be specified.
7597 Initialized the new field char *Processor field to NULL in all ports
7600 Compiler generated registers for interrupt context saving
7601 were not getting allocated.
7603 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7606 Fixed left shift. Will promote the left side of a left shift
7607 if a) left shifting more than size of operand or b) when assigned
7608 to something size > size of left side
7610 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7718 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7720 * sdcc/src/SDCCloop.c:
7721 Previous fix was not good. basic blocks that have "break" or "return" are
7722 not really partof a loop , but live ranges used in these blocks should
7723 be live thru the entire loop, so set partOfLoop but don't add them to
7726 2002-02-21 <johan AT FRIJA>
7728 * src/SDCCcse.c: fixed bug #514308
7730 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7734 statement inside a loop, it was not being considered part of the loop.
7736 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7738 2002-02-10 Karl Bongers <karl AT turbobit.com>
7741 Fixed up SDCDB debugger somewhat. Updated debugger/README
7742 with lots of comments and notes.
