247 on rIfx (genCmp was broken)
249 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
251 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
252 * src/z80/main.c (_keywords[]),
253 * src/SDCCglobal.h (struct options),

338 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
340 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
342 * device/lib/printf_large.c: removed inline assembly for portability and
343 readability. Use printf_fast if speed or size are more important.
344 * src/pic16/gen.c: removed conditions around use of DEBUGpc
345 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
347 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
349 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
350 prevent compiler warning
352 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
354 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
355 moved to level 0 and declared as static. Also they are explicit
356 placed in access bank. This was necessery because some times they
357 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
358 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
359 optimizations. Currently only compare to unsigned char is implemented,
360 * src/pic16/gen.c: added fReturnIdx array,
361 * (struct resolvedIfx) is moved to gen.h and made public,
362 * (struct _G): added sregsAlloc and sregsAllocSet fields,
363 * (aopForSym): added an optimization to directly store in stack of
364 the operand of a SEND iCode,
365 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
366 but as registers instead (AOP_REG) using the fReturnIdx array,
367 * (pic16_freeAsmop): remove the freed register from the
369 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
371 * (pic16_popGetTempRegCond): changed function prototype, now
372 function takes also a bitVector argument v which holds the current
373 set of registers that are allocated for stack access by aopForSym,
374 registers allocated in aopForSym for accessing stack symbols are not
375 any more part of the functions usedRegs field,
376 * (genCall): some times aopOp is called for a stack variable to be
377 send, aopForSym might perform the push, if this is true make sure
378 that genCall doesn't push the variable twice by testing _G.resDirect,
379 * (genFunction): changed testing for unspecified interrupt number
380 from 256 to INTNO_UNSPEC,
381 * modified selection scheme of frame pointer generation. Previously
382 if function did use local registers a frame pointer was generated,
383 now a frame pointer is generated only if function has arguments
384 (that need PLUSW2 register access), or has stack arguments, or the
385 compiler is not instructed to omit the frame pointer,
386 * (genEndFunction): before restoring local registers that were saved
387 in the function preamble, also restore the registers that *might*
388 have been allocated for stack access,
389 * (genRet): removed some old comments,
390 * (genCmp, the active (RN's) version): added a call to the
391 pic16_genCmp_special function to perform the compare with a more
392 robust and optimized way,
393 * (genInline): a feature has been added in inline code generation,
394 which allows a wildcard variable substitution when writing inline
395 assembly. Code is incomplete and experimental therefore undocumented,
396 * (genCast): changed order of aopOp for result and right to allow
397 aopForSym to directly load the result if possible,
398 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
399 perform an optimized compare on some selected special occasions,
400 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
401 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
402 generate an IVT any more,
403 * src/pic16/main.c (pic16_optionsTable): added command line option
405 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
406 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
408 * src/pic16/NOTES: Raphael Neider added in list of active developers
409 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
410 jumptable_end to prevent bug #,
411 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
412 inCond and outCond fields,
413 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
414 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
415 turn off register spilling,
416 * (packRegsForOneUse): synced with other ports' versions although it
417 is not used currently,
418 * (pic16_packRegisters): added an optimization while reading
419 structure bitfields, some registers may be saved (malloc code is
420 decreased by 80 bytes)
422 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
424 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
425 left is a bitfield, if yes, then don't optimize assignment. Perhaps
426 this can be optimized more?
428 2005-03-10 Raphael Neider <rneider AT web.de>
430 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
431 genNearPointerGet): (hopefully) fixed access to bitfields via
432 pointers (p->bitN = x; and x = p->bitN; failed)
434 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
436 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
438 2005-03-09 Raphael Neider <rneider AT web.de>
440 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
442 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
444 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
445 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,

1066 Adding support for replacing ljmps with sjmps in jumptables
1067 generated for switch statements. For now you need to set the
1068 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1069 Now 4 algorithms for mcs51 jumptable generation are used:
1070 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1071 addresses loaded pc-relative for up to 112 cases and stack-pushing
1072 target addresses loaded with offset from dptr for up to 256 cases.

1102 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1104 * added libc directory. The current version of LibC contains string
1105 functions, ctype functions and macros and some functions of the
1106 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1107 be extensively tested in the future. Standard disclaimer here.
1108 Library is not automatically build yet. But one can build it by
1109 invoking 'make' inside the libc directory.

1120 * (pic16_storeForReturn): optimized return of 0,
1121 * (genCmp): experimental code for new genCmp which uses PIC18's
1122 special compare&skip instructions. Initial tests fail some times
1123 with variables grater than 1 byte in size, so new code is disabled,
1124 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1126 * (genCast): began a fix to optimize the casting of a bit to another
1127 bit, now assigning a bitfield to another bitfield will fail, sorry,

1136 and 1 for banking instruction,
1137 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1138 caused stop processing pCodes after a inline assembly block,
1139 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1140 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1141 registers when it shouldn't,
1142 * src/pic16/ralloc.c (allocReg): add preliminary support for
1143 supporting a limited set of temporary registers,
1145 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1147 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1148 genDataPointerSet): ensure assignments always copy in MSB to LSB
1150 (loadRegFromAop): recognize CLRH optimization,
1151 (genFunction): optimize RECEIVE iCodes in reentrant functions
1153 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1155 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4153 loaded with the linker search paths (-L arguments) and the libraries
4154 to be linked with the current source (-l arguments). Changes
4155 currently will affect only the pic16 port.
4156 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4157 include path the port specific paths and port specific libraries,
4158 * gplink command now contains the $3 argument,

4176 Documenting changes from previous commits.
4177 * configure.in (version 1.56),
4178 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4179 when generating output files to configure the pic16 library,
4180 but now I've commented it out, since gputils aren't installed in the
4181 SF compile farm, so library won't compile
4183 * device/lib/Makefile.in (version 1.56): initially I've added in
4184 target 'all' the prerequestive 'model-pic16' so it compiled the
4185 pic16 library, but now I've commented it out for the same reasons
4187 * added targets 'model-pic16' and 'objects-pic16' to compile the
4189 * added target 'port-specific-objects-pic16' to handle the
4190 generated libraries and copy them into the build/ directory
4191 * added target 'clean-intermediate-pic16' to clean intermediate
4192 files into pic16 directory
4193 * in target 'installdirs' added line to create directory pic16 in

4197 added lines to copy all header files to installation path,
4198 * in target 'installdirs' added line create directory for pic16
4199 headers in the installation path

4481 * src/ds390/gen.c (genRightShift): fixed bug #870788
4482 * src/SDCCast.c (decorateType): fixed bug #870781
4484 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4486 PIC16 port related changes:
4487 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4488 added variable stackPos,
4490 * gen.c: genCall, assignResultValue: added support for
4491 pushing/retrieving function parameters to/from stack,
4492 genFunction,genEndFunction: setup stack frame for the
4494 genAddrOf: will be changed according to bug 863624
4496 * added files genutils.c and genutils.h which contain gen*
4497 debugged and optimised functions extracted from gen.c
4499 * glue.c: added variable 'externs' which holds extern symbols,
4500 pic16emitRegularMap: is modified to properly handle relocatable
4501 symbols under the new scheme,
4502 pic16createInterruptVect: is modified
4503 pic16printPublics: is modified to emit 'global' assembler directives,
4504 added pic16_printExterns to print extern symbols,
4505 pic16glue: initializes stack/frame pointer in the beginning of
4506 the assembly output. Temporary hack, will be corrected later,
4507 because gplink yet does not support stack and SDCC does not
4508 yet support a type of crt0.o object to create the final binary.
4510 * Removed many lines that contain 8051 legacy code.
4511 * The code is finally placed under a 'code' directive.
4512 * Added port specific options.
4514 * _process_pragma: simplified since now we do not need *special*
4515 include file to define SFR registers. But a separate header
4516 will be needed. This will be developed later.
4517 * _pic16_parseOptions: added, parses port specific options:
4518 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4519 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4520 --preplace-udata-with=
4522 * _pic16_setDefaultOptions: modified to initialize section names,
4523 but hack is temporarly out of order since it needs improvement.
4524 * _pic16_genAssemblerPreamble: configuration words are emitted by
4525 their address instead of their name. This part is incomplete and
4526 supports only the 18Fxx2 devices. Other devices will emit an error
4527 during assembly since they do not contain the same set of config
4529 * _pic16_genIVT: is modified,
4531 * pcode.c: added definitions for some hardware registers that are needed
4533 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4534 All PCI entries are updated. Now LFSR is supported.
4535 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4536 * added pic16_newpCodeOpLit2 to support instructions with
4537 two literal arguments
4538 * pic16_pCode2str: corrected code that emits assembler instructions
4539 with two literal operands and those that have an access bit modifier
4540 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4541 this fixes a bug which caused some labels to be lost, when an
4542 assembler directive was added, i.e. banksel,
4543 * pic16_FixRegisterBanking: improved logic that causes the insertion
4545 * InlineFunction: functions that are called once, are not any more
4546 inlined. This can be a port option in the future,
4548 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4550 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4551 hold the corresponding uninitialized symbols,
4552 * pic16_allocProcessorRegister: registers have explicit marked the
4554 * pic16_allocInternalRegister: registers are explicit marked as
4556 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4557 processing list, so bit registers were lost,
4560 * ralloc.h: added field 'accessBank' and original symbol operand
4561 in register definition,
4562 * removed the field isMapped from register definition,
4564 ** Several functions have been removed from various sources:
4565 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4566 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4567 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4568 pic16_assignRelocatableRegisters
4570 ** others have been introduced:
4571 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4572 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4574 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4576 * support/scripts/inc2h.pl: changed definition of BIT_AT
4577 to emit 'sbit at' instead of 'bit at'. This was a request.
4579 PIC16 port related preliminary changes:
4580 * gen.c: prefixed function popRegFromString with
4581 pic16_ and all references to it corrected
4582 * pcode.c: all pic16_pc_* hardware registers prefixed
4583 with underscore (_),
4584 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4585 * ralloc.c: newReg(): when register is REG_SFR then
4586 set address to rIdx,
4587 pic16_allocProcessorRegister(): marks register wasUsed=0
4588 pic16_writeUsedRegs(): added a call to assign processor
4589 registers via pic16_assignFixedRegisters
4591 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4593 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4594 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4595 variables in unused register banks. Also the SSEG is placed
4596 wherever there is enough space for it, and IDATA can be anywhere
4597 in internal RAM. For now compile using -Wl-Y[stack_size].
4598 The mem file is different for this option as well, since it
4599 makes no sense of talking about DSEG lenght.
4601 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4603 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4604 in certain cases, e.g. when ROM assignment, patch provided
4605 from Albert den Haan.
4607 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4846 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4848 * src/SDCCast.c (decorateType): disabled a transformation I added in
4849 revision 1.188 (access to fields of a structure at an absolute address);
4850 it breaks with bitfields, extern declarations, and gcse analysis.
4851 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4852 could be assigned through a pointer, so don't complain.
4853 * src/SDCCast.c (astErrors),
4855 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5513 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5515 Fixed bug #621531 (const & volatile confusion in the type chain).
5516 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5609 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5610 fetching of the pointer
5611 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5612 copied from genNearPointerSet()
5613 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5614 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5630 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5631 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5632 type for bits was changed. It resulted in bit variables becoming
5633 global, which is not permitted in PIC 14 assembly output.
5635 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5637 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5650 A few small changes that speed up the peephole optimizer.
5654 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5656 Try to make the peephole optimizer smarter by maintaining
5657 an association between the assembly source code and the
5658 iCodes that originated them. Put this information to use
5659 with a new peephole rule condition "notVolatile" so that
5660 the rules can be aggressive yet still safe.
5665 * src/mcs51/peeph.def
5667 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5671 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5672 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5673 if the left or right operand symbols have the accuse flag set.
5675 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5677 Changed the type of the result of the ! (NOT) operator to char;
5678 previously it returned the same type as the source. This allows
5679 us to eliminate all the genFloatNot functions (all of its target
5680 implementations were very buggy) since !float can use the same

5692 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5693 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5694 during interrupts. Ensure WSAVE is located at a shared bank address.
5695 2. Fixed page selection in some places
5696 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5697 the registers name strings.
5698 4. Fixed "signed / unsigned compare" compiler warnings.
5699 5. The PIC port manages its own allocation of the general purpose
5700 registers, but makes no attempt to reuse them. As a result when
5701 compiling it soon runs out of general purpose registers. Some
5702 additional code was added to the files pcode.c and device.c to walk
5703 through the function call tree and rename the registers so that they
5713 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5714 genPlus() & genMinus() when the result is the same as left or right

5720 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5722 Made bitfield a distinct type from bit so that bitfields
5723 convert as per ANSI C and bits retain their traditional
5724 boolean style behaviour. Implemented bitfield support in
5732 * src/ds390/gen.c: bit v bitfield split
5733 * src/z80/gen.c: New support for bitfields
5734 * support/regression/tests/bitfields.c: reenabled z80,
5737 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5739 Rules 246.x, 247.x relate to bitfields, the others speed up
5740 access to xdata mapped I/O devices.
5742 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5744 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5746 Cleaned up genPackBits and genUnpackBits and added two helper
5747 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5748 for literal assignments in genPackBits (thanks to Frieder for
5754 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5756 Fixed bug #748310 (pointer to function type mishandled when the
5757 function name is omitted). Also fixed a SIGSEGV when a function
5758 attribute (reentrant, etc) is used on a non-function or on a
5759 function but misplaced before the parameter list.
5761 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5763 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5764 * support/Util/SDCCerr.h,

5786 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5788 Made the constant following the "interrupt" keyword optional. If
5789 omitted, the function will not automatically be given an entry
5790 in the interrupt vector table (similar to #pragma NOIV, but
5791 less syntacticly kludgy). The interrupt number is also now
5792 range checked. Also fixed a bug in the high order bit example

5806 * src/SDCCicode.c (operandOperation): rewritten some ops
5807 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5808 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5810 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5811 be re-activated by defining REDUCE_LITERALS)
5812 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5813 unsigned, but are signed by default
5814 * src/SDCCval.c (constVal): rearranged
5815 * src/SDCCval.c (valMod): preliminary fix
5816 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6321 * src/SDCCmain.c: linkOptions is changed to set *,
6322 added if/endif conditional macros to remove options help
6323 messages from optionsTable when a port is not configured, added
6324 support for the PIc16 port in the ports table, when executing
6325 the compiler with no port specified on command line, a default
6326 port is selected with the new macro DEFAULT_PORT which is
6327 defined in port.h, in setDefaultOptions() linkOptions is removed
6328 from initialization assignment, since now it is a set,
6329 parseCmdLine uses setParseWithComma for linkOptions, in
6330 linkEdit() linkOptions are accessed with new function indexSet()
6331 which returns the i'th item of a set variable. See SDCCset.c, in
6332 linkEdit() when calling buildCmdLine(), added linkOptions as
6333 last argument. Now users can pass arguments to gplink via the
6334 -Wl option, main() uses pic16glue() to glue up pic16 programs

6347 * src/pic16/main.c: __config directives are commented out to stop
6348 gpasm complaining and test the linkage with gplink, _linkCmd and
6349 _asmCmd changed to be more gplink and gpasm friendly
6350 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6351 produced an error when parsed, peep rule 12 is added to utilize
6352 movff, but it is commented out since the pCode does not support
6353 yet a command with 2 address arguments
6355 2003-05-18 <johan AT balder>
6357 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6384 2003-05-11 Borut Razem <borut.razem AT siol.net>
6386 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6387 the path of bin directory, so that PATH is the only env. variable, which has to be set

7403 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7405 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7406 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7407 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7409 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7410 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7412 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7413 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7415 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7416 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7418 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7420 * in \sdcc\as\mcs51\ changed these files in order to create an
7421 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7422 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7423 following files to include the previous two files: aslink.dsp,
7424 Makefile.aslink, Makefile.bcc, and Makefile.in.
7426 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7427 .adb instead of .cdb
7429 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7431 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7432 value from option --iram-size.
7434 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7436 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7439 2002-09-18 <wiml AT hhhh.org>
7441 * SDCClrange.h: exposed setFromRange() and setToRange()
7442 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7443 packRegsForAccUse() (bug 542397)
7444 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7445 multiple times and emitting the fetch operations more than once
7446 added aopGetUsesAcc() function to allow binary operators to
7447 fetch their operands in the correct order; made genMinus() emit
7448 compact code for X = LITERAL - Y
7450 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7451 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7452 sprintf() in line 1267.
7454 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7455 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7458 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7459 Changes to aslink (All the changes are marked with 'JCF'):
7461 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7464 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7465 area BSEG. Also moves, if possible, the DATA area down into the internal
7466 ram so more space is available.
7468 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7471 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7472 not bytes. Function summary() which creates a memory usage summary
7473 file with extension .mem. Reports of overlaping stack and small stack
7474 size. If the space for the stack is less than 16 bytes aslink trows a
7477 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7478 the 8051. Option 'y' for memory summary output file.
7480 Changes to sdcc (All the changes are marked with 'JCF'):
7482 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7484 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7485 overlaying area for it (uses RegBankUsed[4]).
7487 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7488 bank zero as used by default. By default aslink locates the stack
7489 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7490 the creation of the .mem file. Delegates the allocation of data area
7491 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7492 the begining of the stack area to aslink.
7494 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7495 glue() in SDCCglue.c creates an area for it.
7497 2002-09-03 Borut Razem <borut.razem AT siol.net>
7498 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7499 sdcc/src/pic/glue.c:
7500 introduced atexit() handler for teporay files removal in case of
7501 errors, assertions, ...
7503 2002-08-29 Borut Razem <borut.razem AT siol.net>
7504 * sdcc/support/cpp2/auto-host_vc_in.h:
7505 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7506 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7507 Maybe there is a similar problem with BORLANDC? It should be checked!
7509 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7510 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7511 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7512 was not executed, and the compiler (cl) launched a warning:
7513 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7515 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7516 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7518 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7519 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
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 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7524 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7525 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7526 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7527 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7528 - added Release configuration in VS projects
7529 - review of compiler an linker options
7530 - VC .exe files are generated in bin_vc directory, not to interfere
7531 with binaries generated from other projects (cygwin, mingw, bcc ...)
7533 * sdcc/src/yacc.dsp: added
7535 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7536 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7537 and insert the version number definitions from .version
7539 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7541 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7542 added - genarate auto-host.h using auto-host_vc_in.h as template
7545 removed from CVS, generated automatically
7547 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7548 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7550 2002-08-11 Borut Razem <borut.razem AT siol.net>
7551 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7553 2002-08-10 Borut Razem <borut.razem AT siol.net>
7554 * src/SDCCmain.c (main):
7555 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7556 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7557 The consequence was that some temporary files were not removed.
7560 unification of code in functions tempfilename() and tempfile():
7561 function tempnam() is defined in Visual Studio 6.0 and .NET
7563 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7565 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7566 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7567 - removed compiler command line option /WX: Treats all warnings as errors
7568 - update a list of source files, included into the project
7570 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7571 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7572 changed project type to Generic Project so that can be correcly converted to VS.NET project
7574 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7576 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7578 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7580 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7581 added return 0 statements after assert() to make compiler happy
7583 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7584 added newline in the def file to keep MSC compiler satisfied
7586 * sdcc/src/z80/gen.c:
7587 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7588 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7589 - solved MSC error in function aopDump()
7591 * sdcc_vc.h: define PREFIX as "\\sdcc"
7593 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7594 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7642 Added -p option. Allows port dependent processor to be specified.
7645 Initialized the new field char *Processor field to NULL in all ports
7648 Compiler generated registers for interrupt context saving
7649 were not getting allocated.
7651 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7654 Fixed left shift. Will promote the left side of a left shift
7655 if a) left shifting more than size of operand or b) when assigned
7656 to something size > size of left side
7658 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7660 tons of changes. Register allocation has been
7661 rewritten. Added customization for the various PICs. Flow

7766 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7768 * sdcc/src/SDCCloop.c:
7769 Previous fix was not good. basic blocks that have "break" or "return" are
7770 not really partof a loop , but live ranges used in these blocks should
7771 be live thru the entire loop, so set partOfLoop but don't add them to
7774 2002-02-21 <johan AT FRIJA>
7776 * src/SDCCcse.c: fixed bug #514308
7778 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7781 Fixed BUG #519583. If a conditional block ended in a return/break
7782 statement inside a loop, it was not being considered part of the loop.
7784 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7786 2002-02-10 Karl Bongers <karl AT turbobit.com>
7789 Fixed up SDCDB debugger somewhat. Updated debugger/README
7790 with lots of comments and notes.
7792 * device/examples/test2.c:
7793 Fix bug, "red" variable not being initialized(compiler complained).
7795 * device/examples/Makefile, examples/test3.c:

7797 for use as a multiple module SDCDB test case.
7799 * sim/ucsim/cmd.src/cmdset.cc:
7800 Took out debug printfs in ucsim "next" command.
7803 Karl and Johan start ucsim XA support. Most dissassembly working,

7844 set preprocessor defines (depending on options)
7846 * src/SDCCicode.c, src/SDCCicode.h:
7847 changes made to handle multiple sends & receives
7850 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
