450 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
452 * device/include/stdint.h: added
453 * device/lib/abs.c: added
454 * device/lib/labs.c: added
455 * device/include/stdlib.h: added abs() and labs() prototypes
456 * device/lib/libsdcc.lib: added abs and labs
457 * device/include/float.h,
458 * device/lib/_fsmul.c,
459 * device/lib/printf_fast.c,
460 * device/lib/printf_tiny.c: updated comments
462 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
464 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
467 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
469 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
470 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
472 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
474 * device/lib/printf_large.c: removed inline assembly for portability and
475 readability. Use printf_fast if speed or size are more important.
476 * src/pic16/gen.c: removed conditions around use of DEBUGpc
477 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
479 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
481 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
482 prevent compiler warning
484 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
486 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
487 moved to level 0 and declared as static. Also they are explicit
488 placed in access bank. This was necessery because some times they
489 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
490 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
491 optimizations. Currently only compare to unsigned char is implemented,
492 * src/pic16/gen.c: added fReturnIdx array,
493 * (struct resolvedIfx) is moved to gen.h and made public,
494 * (struct _G): added sregsAlloc and sregsAllocSet fields,
495 * (aopForSym): added an optimization to directly store in stack of
496 the operand of a SEND iCode,
497 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
498 but as registers instead (AOP_REG) using the fReturnIdx array,
499 * (pic16_freeAsmop): remove the freed register from the
501 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
503 * (pic16_popGetTempRegCond): changed function prototype, now
504 function takes also a bitVector argument v which holds the current
505 set of registers that are allocated for stack access by aopForSym,
506 registers allocated in aopForSym for accessing stack symbols are not
507 any more part of the functions usedRegs field,
508 * (genCall): some times aopOp is called for a stack variable to be
509 send, aopForSym might perform the push, if this is true make sure
510 that genCall doesn't push the variable twice by testing _G.resDirect,
511 * (genFunction): changed testing for unspecified interrupt number
512 from 256 to INTNO_UNSPEC,
513 * modified selection scheme of frame pointer generation. Previously
514 if function did use local registers a frame pointer was generated,
515 now a frame pointer is generated only if function has arguments
516 (that need PLUSW2 register access), or has stack arguments, or the
517 compiler is not instructed to omit the frame pointer,
518 * (genEndFunction): before restoring local registers that were saved
519 in the function preamble, also restore the registers that *might*
520 have been allocated for stack access,
521 * (genRet): removed some old comments,
522 * (genCmp, the active (RN's) version): added a call to the
523 pic16_genCmp_special function to perform the compare with a more
524 robust and optimized way,
525 * (genInline): a feature has been added in inline code generation,
526 which allows a wildcard variable substitution when writing inline
527 assembly. Code is incomplete and experimental therefore undocumented,
528 * (genCast): changed order of aopOp for result and right to allow
529 aopForSym to directly load the result if possible,
530 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
531 perform an optimized compare on some selected special occasions,
532 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
533 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
534 generate an IVT any more,
535 * src/pic16/main.c (pic16_optionsTable): added command line option
537 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
538 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
540 * src/pic16/NOTES: Raphael Neider added in list of active developers
541 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
542 jumptable_end to prevent bug #,
543 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
544 inCond and outCond fields,
545 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
546 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
547 turn off register spilling,
548 * (packRegsForOneUse): synced with other ports' versions although it
549 is not used currently,
550 * (pic16_packRegisters): added an optimization while reading
551 structure bitfields, some registers may be saved (malloc code is
552 decreased by 80 bytes)
554 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
556 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
557 left is a bitfield, if yes, then don't optimize assignment. Perhaps
558 this can be optimized more?
560 2005-03-10 Raphael Neider <rneider AT web.de>
562 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
563 genNearPointerGet): (hopefully) fixed access to bitfields via
564 pointers (p->bitN = x; and x = p->bitN; failed)

1236 * added libc directory. The current version of LibC contains string
1237 functions, ctype functions and macros and some functions of the
1238 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1239 be extensively tested in the future. Standard disclaimer here.

1252 * (pic16_storeForReturn): optimized return of 0,
1253 * (genCmp): experimental code for new genCmp which uses PIC18's
1254 special compare&skip instructions. Initial tests fail some times
1255 with variables grater than 1 byte in size, so new code is disabled,
1256 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1258 * (genCast): began a fix to optimize the casting of a bit to another
1259 bit, now assigning a bitfield to another bitfield will fail, sorry,

1273 registers when it shouldn't,
1274 * src/pic16/ralloc.c (allocReg): add preliminary support for
1275 supporting a limited set of temporary registers,
1277 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1283 (genFunction): optimize RECEIVE iCodes in reentrant functions
1285 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4284 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4285 loaded with the linker search paths (-L arguments) and the libraries
4286 to be linked with the current source (-l arguments). Changes
4287 currently will affect only the pic16 port.
4288 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4289 include path the port specific paths and port specific libraries,
4290 * gplink command now contains the $3 argument,
4291 * src/pic16/device.h,
4292 * src/pic16/device.c,: structure PIC_device is made public and

4308 Documenting changes from previous commits.
4309 * configure.in (version 1.56),
4310 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4311 when generating output files to configure the pic16 library,
4312 but now I've commented it out, since gputils aren't installed in the
4313 SF compile farm, so library won't compile
4315 * device/lib/Makefile.in (version 1.56): initially I've added in
4316 target 'all' the prerequestive 'model-pic16' so it compiled the
4317 pic16 library, but now I've commented it out for the same reasons
4319 * added targets 'model-pic16' and 'objects-pic16' to compile the
4321 * added target 'port-specific-objects-pic16' to handle the
4322 generated libraries and copy them into the build/ directory
4323 * added target 'clean-intermediate-pic16' to clean intermediate
4324 files into pic16 directory
4325 * in target 'installdirs' added line to create directory pic16 in

4347 option so that it actually works. Made it specific to the z80, since
4348 the gbz80 doesn't have these kinds of I/O ports.
4350 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4376 via literal number. The symbol is placed in the corresponding
4377 position of the data ram
4378 * (pic16_dump_section): relocatable and absolute uninitialized
4379 data are now emitted in sorted order to reduce section naming,
4380 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4381 weren't marked as being in the access bank,

4385 Added portion of GNU PIC Library under the directory
4386 device/include/pic16 and device/lib/pic16. These files
4387 contain the declarations of SFRs for the PIC18Fxx2 devices.
4388 The directory is initialized via configure from toplevel.

4458 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4459 UPPER for immediate operands,
4460 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4462 * src/pic16/peeph.def: all peepholes with movff are commented out,
4463 because there is a problem in the pcode peep optimizer,
4464 * src/pic16/ralloc.c: the register allocator can now reuse local
4465 function symbols for another function. This saves register usage.
4466 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4468 Added file src/pic16/NOTES with information about program writing on
4469 the current port version.

4501 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4504 * src/z80/main.c: added missed needLinkerScript flags (more than
4505 one port structure defined in these file)
4506 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4557 include information about variables allocated to the overlay
4560 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4562 * as/mcs51/lkmain.c: Help about -Y option

4572 LEFT_OP (left shift)
4574 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4576 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4577 (default behaviour).
4579 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4581 A python script to validate compiler diagnostic messages. It can be
4582 used to verify that sdcc complains about bad c source code and
4583 gives a good location of the error.
4584 * support/valdiag/Makefile,
4585 * support/valdiag/valdiag.py,
4586 * support/valdiag/tests/*
4588 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4601 * src/common.h: added ifndef/define/endif macros
4602 around the header file.
4603 Bug reported from Jesus Calvino-Fraga
4605 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4607 * sdcc.spec: updated
4608 * device/include/Makefile.in: don't install CVS directories
4609 * device/lib/Makefile.in: added removal of CVS directories after install
4610 * doc/Makefile: fixed install, added local_icons
4611 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4612 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4613 * src/ds390/gen.c (genRightShift): fixed bug #870788
4614 * src/SDCCast.c (decorateType): fixed bug #870781
4616 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4618 PIC16 port related changes:
4619 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4620 added variable stackPos,
4622 * gen.c: genCall, assignResultValue: added support for
4623 pushing/retrieving function parameters to/from stack,
4624 genFunction,genEndFunction: setup stack frame for the
4626 genAddrOf: will be changed according to bug 863624
4628 * added files genutils.c and genutils.h which contain gen*
4629 debugged and optimised functions extracted from gen.c
4631 * glue.c: added variable 'externs' which holds extern symbols,
4632 pic16emitRegularMap: is modified to properly handle relocatable
4633 symbols under the new scheme,
4634 pic16createInterruptVect: is modified
4635 pic16printPublics: is modified to emit 'global' assembler directives,
4636 added pic16_printExterns to print extern symbols,
4637 pic16glue: initializes stack/frame pointer in the beginning of
4638 the assembly output. Temporary hack, will be corrected later,
4639 because gplink yet does not support stack and SDCC does not
4640 yet support a type of crt0.o object to create the final binary.
4642 * Removed many lines that contain 8051 legacy code.
4643 * The code is finally placed under a 'code' directive.
4644 * Added port specific options.
4646 * _process_pragma: simplified since now we do not need *special*
4647 include file to define SFR registers. But a separate header
4648 will be needed. This will be developed later.
4649 * _pic16_parseOptions: added, parses port specific options:
4650 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4651 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4652 --preplace-udata-with=
4654 * _pic16_setDefaultOptions: modified to initialize section names,
4655 but hack is temporarly out of order since it needs improvement.
4656 * _pic16_genAssemblerPreamble: configuration words are emitted by
4657 their address instead of their name. This part is incomplete and
4658 supports only the 18Fxx2 devices. Other devices will emit an error
4659 during assembly since they do not contain the same set of config
4661 * _pic16_genIVT: is modified,
4663 * pcode.c: added definitions for some hardware registers that are needed
4665 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4666 All PCI entries are updated. Now LFSR is supported.
4667 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4668 * added pic16_newpCodeOpLit2 to support instructions with
4669 two literal arguments
4670 * pic16_pCode2str: corrected code that emits assembler instructions
4671 with two literal operands and those that have an access bit modifier
4672 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4673 this fixes a bug which caused some labels to be lost, when an
4674 assembler directive was added, i.e. banksel,
4675 * pic16_FixRegisterBanking: improved logic that causes the insertion
4677 * InlineFunction: functions that are called once, are not any more
4678 inlined. This can be a port option in the future,
4680 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4682 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4683 hold the corresponding uninitialized symbols,
4684 * pic16_allocProcessorRegister: registers have explicit marked the
4686 * pic16_allocInternalRegister: registers are explicit marked as
4688 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4689 processing list, so bit registers were lost,
4692 * ralloc.h: added field 'accessBank' and original symbol operand
4693 in register definition,
4694 * removed the field isMapped from register definition,
4696 ** Several functions have been removed from various sources:
4697 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4698 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4699 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4700 pic16_assignRelocatableRegisters
4702 ** others have been introduced:
4703 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4704 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4706 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4708 * support/scripts/inc2h.pl: changed definition of BIT_AT
4709 to emit 'sbit at' instead of 'bit at'. This was a request.
4711 PIC16 port related preliminary changes:
4712 * gen.c: prefixed function popRegFromString with
4713 pic16_ and all references to it corrected
4714 * pcode.c: all pic16_pc_* hardware registers prefixed
4715 with underscore (_),
4716 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4717 * ralloc.c: newReg(): when register is REG_SFR then
4718 set address to rIdx,
4719 pic16_allocProcessorRegister(): marks register wasUsed=0
4720 pic16_writeUsedRegs(): added a call to assign processor
4721 registers via pic16_assignFixedRegisters
4723 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4725 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4726 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4727 variables in unused register banks. Also the SSEG is placed
4728 wherever there is enough space for it, and IDATA can be anywhere
4729 in internal RAM. For now compile using -Wl-Y[stack_size].
4730 The mem file is different for this option as well, since it
4731 makes no sense of talking about DSEG lenght.
4733 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4735 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4736 in certain cases, e.g. when ROM assignment, patch provided
4737 from Albert den Haan.
4739 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5624 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5625 support for standard C idiom of memory mapped variables; for
5626 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5627 to xdata int at 0x1234 tempvar = 1.
5628 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5629 provided by Akiya ISHIDA

5645 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5647 Fixed bug #621531 (const & volatile confusion in the type chain).
5648 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5740 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5741 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5742 fetching of the pointer
5743 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5744 copied from genNearPointerSet()
5745 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5746 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5747 If they pop r0/r1 they must be called in the opposite order than aopOp().
5748 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5749 (resp. --stack-auto), prepared for --xstack

5758 these ports have their own __sdcc_external_start()
5760 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5762 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5763 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5764 type for bits was changed. It resulted in bit variables becoming
5765 global, which is not permitted in PIC 14 assembly output.
5767 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5769 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5782 A few small changes that speed up the peephole optimizer.
5786 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5788 Try to make the peephole optimizer smarter by maintaining
5789 an association between the assembly source code and the
5790 iCodes that originated them. Put this information to use
5791 with a new peephole rule condition "notVolatile" so that
5792 the rules can be aggressive yet still safe.
5797 * src/mcs51/peeph.def
5799 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5803 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5804 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5805 if the left or right operand symbols have the accuse flag set.
5807 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5809 Changed the type of the result of the ! (NOT) operator to char;
5810 previously it returned the same type as the source. This allows
5811 us to eliminate all the genFloatNot functions (all of its target
5812 implementations were very buggy) since !float can use the same
5815 * src/SDCCicode.c (ast2iCode): ! returns char

5824 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5825 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5826 during interrupts. Ensure WSAVE is located at a shared bank address.
5827 2. Fixed page selection in some places
5828 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5829 the registers name strings.
5830 4. Fixed "signed / unsigned compare" compiler warnings.
5831 5. The PIC port manages its own allocation of the general purpose
5832 registers, but makes no attempt to reuse them. As a result when
5833 compiling it soon runs out of general purpose registers. Some
5834 additional code was added to the files pcode.c and device.c to walk
5835 through the function call tree and rename the registers so that they
5845 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5846 genPlus() & genMinus() when the result is the same as left or right

5852 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5854 Made bitfield a distinct type from bit so that bitfields
5855 convert as per ANSI C and bits retain their traditional
5856 boolean style behaviour. Implemented bitfield support in
5864 * src/ds390/gen.c: bit v bitfield split
5865 * src/z80/gen.c: New support for bitfields
5866 * support/regression/tests/bitfields.c: reenabled z80,
5869 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5871 Rules 246.x, 247.x relate to bitfields, the others speed up
5872 access to xdata mapped I/O devices.
5874 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5876 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5878 Cleaned up genPackBits and genUnpackBits and added two helper
5879 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5880 for literal assignments in genPackBits (thanks to Frieder for
5886 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5888 Fixed bug #748310 (pointer to function type mishandled when the
5889 function name is omitted). Also fixed a SIGSEGV when a function
5890 attribute (reentrant, etc) is used on a non-function or on a
5891 function but misplaced before the parameter list.
5893 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5895 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5896 * support/Util/SDCCerr.h,
5897 * support/Util/SDCCerr.c: Added func attr misuse error msg

5918 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5920 Made the constant following the "interrupt" keyword optional. If
5921 omitted, the function will not automatically be given an entry
5922 in the interrupt vector table (similar to #pragma NOIV, but
5923 less syntacticly kludgy). The interrupt number is also now
5924 range checked. Also fixed a bug in the high order bit example

5938 * src/SDCCicode.c (operandOperation): rewritten some ops
5939 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5940 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5942 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5943 be re-activated by defining REDUCE_LITERALS)
5944 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5945 unsigned, but are signed by default
5946 * src/SDCCval.c (constVal): rearranged
5947 * src/SDCCval.c (valMod): preliminary fix
5948 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6454 added if/endif conditional macros to remove options help
6455 messages from optionsTable when a port is not configured, added
6456 support for the PIc16 port in the ports table, when executing
6457 the compiler with no port specified on command line, a default
6458 port is selected with the new macro DEFAULT_PORT which is
6459 defined in port.h, in setDefaultOptions() linkOptions is removed
6460 from initialization assignment, since now it is a set,
6461 parseCmdLine uses setParseWithComma for linkOptions, in
6462 linkEdit() linkOptions are accessed with new function indexSet()
6463 which returns the i'th item of a set variable. See SDCCset.c, in
6464 linkEdit() when calling buildCmdLine(), added linkOptions as
6465 last argument. Now users can pass arguments to gplink via the
6466 -Wl option, main() uses pic16glue() to glue up pic16 programs

6480 gpasm complaining and test the linkage with gplink, _linkCmd and
6481 _asmCmd changed to be more gplink and gpasm friendly
6482 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6483 produced an error when parsed, peep rule 12 is added to utilize
6484 movff, but it is commented out since the pCode does not support
6485 yet a command with 2 address arguments
6487 2003-05-18 <johan AT balder>
6489 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6512 2003-05-12 Borut Razem <borut.razem AT siol.net>
6514 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6516 2003-05-11 Borut Razem <borut.razem AT siol.net>
6518 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6519 the path of bin directory, so that PATH is the only env. variable, which has to be set
6520 in case of standard installation.

7528 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7530 2003-01-04 <johan AT balder>
7532 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7534 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7547 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7548 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7550 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7552 * in \sdcc\as\mcs51\ changed these files in order to create an
7553 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7554 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7555 following files to include the previous two files: aslink.dsp,
7556 Makefile.aslink, Makefile.bcc, and Makefile.in.
7558 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7559 .adb instead of .cdb
7561 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7563 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7564 value from option --iram-size.
7566 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7568 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7571 2002-09-18 <wiml AT hhhh.org>
7573 * SDCClrange.h: exposed setFromRange() and setToRange()
7574 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7575 packRegsForAccUse() (bug 542397)
7576 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7577 multiple times and emitting the fetch operations more than once
7578 added aopGetUsesAcc() function to allow binary operators to
7579 fetch their operands in the correct order; made genMinus() emit
7580 compact code for X = LITERAL - Y
7582 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7583 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7584 sprintf() in line 1267.
7586 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7587 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7590 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7591 Changes to aslink (All the changes are marked with 'JCF'):
7593 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7596 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7597 area BSEG. Also moves, if possible, the DATA area down into the internal
7598 ram so more space is available.
7600 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7603 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7604 not bytes. Function summary() which creates a memory usage summary
7605 file with extension .mem. Reports of overlaping stack and small stack
7606 size. If the space for the stack is less than 16 bytes aslink trows a
7609 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7610 the 8051. Option 'y' for memory summary output file.
7612 Changes to sdcc (All the changes are marked with 'JCF'):
7614 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7616 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7617 overlaying area for it (uses RegBankUsed[4]).
7619 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7620 bank zero as used by default. By default aslink locates the stack
7621 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7622 the creation of the .mem file. Delegates the allocation of data area
7623 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7624 the begining of the stack area to aslink.
7626 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7627 glue() in SDCCglue.c creates an area for it.
7629 2002-09-03 Borut Razem <borut.razem AT siol.net>
7630 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7631 sdcc/src/pic/glue.c:
7632 introduced atexit() handler for teporay files removal in case of
7633 errors, assertions, ...
7635 2002-08-29 Borut Razem <borut.razem AT siol.net>
7636 * sdcc/support/cpp2/auto-host_vc_in.h:
7637 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7638 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7639 Maybe there is a similar problem with BORLANDC? It should be checked!
7641 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7642 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7643 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7644 was not executed, and the compiler (cl) launched a warning:
7645 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7647 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7648 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7650 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7651 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7653 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7654 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7655 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7656 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7657 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7658 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7659 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7660 - added Release configuration in VS projects
7661 - review of compiler an linker options
7662 - VC .exe files are generated in bin_vc directory, not to interfere
7663 with binaries generated from other projects (cygwin, mingw, bcc ...)
7665 * sdcc/src/yacc.dsp: added
7667 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7668 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7669 and insert the version number definitions from .version
7671 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7673 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7674 added - genarate auto-host.h using auto-host_vc_in.h as template
7677 removed from CVS, generated automatically
7679 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7680 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7682 2002-08-11 Borut Razem <borut.razem AT siol.net>
7683 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7685 2002-08-10 Borut Razem <borut.razem AT siol.net>
7686 * src/SDCCmain.c (main):
7687 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7688 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7689 The consequence was that some temporary files were not removed.
7692 unification of code in functions tempfilename() and tempfile():
7693 function tempnam() is defined in Visual Studio 6.0 and .NET
7695 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7697 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7698 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7699 - removed compiler command line option /WX: Treats all warnings as errors
7700 - update a list of source files, included into the project
7702 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7703 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7704 changed project type to Generic Project so that can be correcly converted to VS.NET project
7706 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7708 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7710 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7712 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7713 added return 0 statements after assert() to make compiler happy
7715 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7716 added newline in the def file to keep MSC compiler satisfied
7718 * sdcc/src/z80/gen.c:
7719 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7720 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7721 - solved MSC error in function aopDump()
7723 * sdcc_vc.h: define PREFIX as "\\sdcc"
7725 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7726 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7774 Added -p option. Allows port dependent processor to be specified.
7777 Initialized the new field char *Processor field to NULL in all ports
7780 Compiler generated registers for interrupt context saving
7781 were not getting allocated.
7783 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7786 Fixed left shift. Will promote the left side of a left shift
7787 if a) left shifting more than size of operand or b) when assigned
7788 to something size > size of left side
7790 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7792 tons of changes. Register allocation has been
7793 rewritten. Added customization for the various PICs. Flow
