447 immedDom() returning wrong block; probably fixes bug #1160833)
449 2005-03-20 Borut Razem <borut.razem AT siol.net>
451 * support/scripts/inc2h.pl: WIN32 port
453 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

457 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
459 * device/include/stdint.h: added
460 * device/lib/abs.c: added
461 * device/lib/labs.c: added
462 * device/include/stdlib.h: added abs() and labs() prototypes
463 * device/lib/libsdcc.lib: added abs and labs
464 * device/include/float.h,
465 * device/lib/_fsmul.c,
466 * device/lib/printf_fast.c,
467 * device/lib/printf_tiny.c: updated comments
469 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
471 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
474 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
476 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
477 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
479 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
481 * device/lib/printf_large.c: removed inline assembly for portability and
482 readability. Use printf_fast if speed or size are more important.
483 * src/pic16/gen.c: removed conditions around use of DEBUGpc
484 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
486 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
488 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
489 prevent compiler warning
491 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
493 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
494 moved to level 0 and declared as static. Also they are explicit
495 placed in access bank. This was necessery because some times they
496 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
497 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
498 optimizations. Currently only compare to unsigned char is implemented,
499 * src/pic16/gen.c: added fReturnIdx array,
500 * (struct resolvedIfx) is moved to gen.h and made public,
501 * (struct _G): added sregsAlloc and sregsAllocSet fields,
502 * (aopForSym): added an optimization to directly store in stack of
503 the operand of a SEND iCode,
504 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
505 but as registers instead (AOP_REG) using the fReturnIdx array,
506 * (pic16_freeAsmop): remove the freed register from the
508 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
510 * (pic16_popGetTempRegCond): changed function prototype, now
511 function takes also a bitVector argument v which holds the current
512 set of registers that are allocated for stack access by aopForSym,
513 registers allocated in aopForSym for accessing stack symbols are not
514 any more part of the functions usedRegs field,
515 * (genCall): some times aopOp is called for a stack variable to be
516 send, aopForSym might perform the push, if this is true make sure
517 that genCall doesn't push the variable twice by testing _G.resDirect,
518 * (genFunction): changed testing for unspecified interrupt number
519 from 256 to INTNO_UNSPEC,
520 * modified selection scheme of frame pointer generation. Previously
521 if function did use local registers a frame pointer was generated,
522 now a frame pointer is generated only if function has arguments
523 (that need PLUSW2 register access), or has stack arguments, or the
524 compiler is not instructed to omit the frame pointer,
525 * (genEndFunction): before restoring local registers that were saved
526 in the function preamble, also restore the registers that *might*
527 have been allocated for stack access,
528 * (genRet): removed some old comments,
529 * (genCmp, the active (RN's) version): added a call to the
530 pic16_genCmp_special function to perform the compare with a more
531 robust and optimized way,
532 * (genInline): a feature has been added in inline code generation,
533 which allows a wildcard variable substitution when writing inline
534 assembly. Code is incomplete and experimental therefore undocumented,
535 * (genCast): changed order of aopOp for result and right to allow
536 aopForSym to directly load the result if possible,
537 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
538 perform an optimized compare on some selected special occasions,
539 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
540 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
541 generate an IVT any more,
542 * src/pic16/main.c (pic16_optionsTable): added command line option
544 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
545 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
547 * src/pic16/NOTES: Raphael Neider added in list of active developers
548 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
549 jumptable_end to prevent bug #,
550 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
551 inCond and outCond fields,
552 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
553 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
554 turn off register spilling,
555 * (packRegsForOneUse): synced with other ports' versions although it
556 is not used currently,
557 * (pic16_packRegisters): added an optimization while reading
558 structure bitfields, some registers may be saved (malloc code is
559 decreased by 80 bytes)
561 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
563 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
564 left is a bitfield, if yes, then don't optimize assignment. Perhaps
565 this can be optimized more?
567 2005-03-10 Raphael Neider <rneider AT web.de>
569 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
570 genNearPointerGet): (hopefully) fixed access to bitfields via
571 pointers (p->bitN = x; and x = p->bitN; failed)

1206 generated for switch statements. For now you need to set the
1207 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1208 Now 4 algorithms for mcs51 jumptable generation are used:
1209 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1243 * added libc directory. The current version of LibC contains string
1244 functions, ctype functions and macros and some functions of the
1245 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1246 be extensively tested in the future. Standard disclaimer here.
1247 Library is not automatically build yet. But one can build it by

1259 * (pic16_storeForReturn): optimized return of 0,
1260 * (genCmp): experimental code for new genCmp which uses PIC18's
1261 special compare&skip instructions. Initial tests fail some times
1262 with variables grater than 1 byte in size, so new code is disabled,
1263 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1265 * (genCast): began a fix to optimize the casting of a bit to another
1266 bit, now assigning a bitfield to another bitfield will fail, sorry,

1281 * src/pic16/ralloc.c (allocReg): add preliminary support for
1282 supporting a limited set of temporary registers,
1284 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1290 (genFunction): optimize RECEIVE iCodes in reentrant functions
1292 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4289 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4291 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4292 loaded with the linker search paths (-L arguments) and the libraries
4293 to be linked with the current source (-l arguments). Changes
4294 currently will affect only the pic16 port.
4295 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4296 include path the port specific paths and port specific libraries,
4297 * gplink command now contains the $3 argument,
4298 * src/pic16/device.h,
4299 * src/pic16/device.c,: structure PIC_device is made public and

4315 Documenting changes from previous commits.
4316 * configure.in (version 1.56),
4317 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4318 when generating output files to configure the pic16 library,
4319 but now I've commented it out, since gputils aren't installed in the
4320 SF compile farm, so library won't compile
4322 * device/lib/Makefile.in (version 1.56): initially I've added in
4323 target 'all' the prerequestive 'model-pic16' so it compiled the
4324 pic16 library, but now I've commented it out for the same reasons
4326 * added targets 'model-pic16' and 'objects-pic16' to compile the
4328 * added target 'port-specific-objects-pic16' to handle the
4329 generated libraries and copy them into the build/ directory
4330 * added target 'clean-intermediate-pic16' to clean intermediate
4331 files into pic16 directory
4332 * in target 'installdirs' added line to create directory pic16 in

4336 added lines to copy all header files to installation path,
4337 * in target 'installdirs' added line create directory for pic16
4338 headers in the installation path

4354 option so that it actually works. Made it specific to the z80, since
4355 the gbz80 doesn't have these kinds of I/O ports.
4357 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4359 * device/include/z180.h,

4383 via literal number. The symbol is placed in the corresponding
4384 position of the data ram
4385 * (pic16_dump_section): relocatable and absolute uninitialized
4386 data are now emitted in sorted order to reduce section naming,
4387 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4388 weren't marked as being in the access bank,

4465 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4466 UPPER for immediate operands,
4467 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4469 * src/pic16/peeph.def: all peepholes with movff are commented out,
4470 because there is a problem in the pcode peep optimizer,
4471 * src/pic16/ralloc.c: the register allocator can now reuse local
4472 function symbols for another function. This saves register usage.
4473 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4475 Added file src/pic16/NOTES with information about program writing on
4476 the current port version.

4564 include information about variables allocated to the overlay
4567 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4569 * as/mcs51/lkmain.c: Help about -Y option

4579 LEFT_OP (left shift)
4581 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4583 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4584 (default behaviour).
4586 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4588 A python script to validate compiler diagnostic messages. It can be
4589 used to verify that sdcc complains about bad c source code and
4590 gives a good location of the error.
4591 * support/valdiag/Makefile,
4592 * support/valdiag/valdiag.py,
4593 * support/valdiag/tests/*
4595 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4608 * src/common.h: added ifndef/define/endif macros
4609 around the header file.
4610 Bug reported from Jesus Calvino-Fraga
4612 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4614 * sdcc.spec: updated
4615 * device/include/Makefile.in: don't install CVS directories
4616 * device/lib/Makefile.in: added removal of CVS directories after install
4617 * doc/Makefile: fixed install, added local_icons
4618 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4619 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4620 * src/ds390/gen.c (genRightShift): fixed bug #870788
4621 * src/SDCCast.c (decorateType): fixed bug #870781
4623 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4625 PIC16 port related changes:
4626 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4627 added variable stackPos,
4629 * gen.c: genCall, assignResultValue: added support for
4630 pushing/retrieving function parameters to/from stack,
4631 genFunction,genEndFunction: setup stack frame for the
4633 genAddrOf: will be changed according to bug 863624
4635 * added files genutils.c and genutils.h which contain gen*
4636 debugged and optimised functions extracted from gen.c
4638 * glue.c: added variable 'externs' which holds extern symbols,
4639 pic16emitRegularMap: is modified to properly handle relocatable
4640 symbols under the new scheme,
4641 pic16createInterruptVect: is modified
4642 pic16printPublics: is modified to emit 'global' assembler directives,
4643 added pic16_printExterns to print extern symbols,
4644 pic16glue: initializes stack/frame pointer in the beginning of
4645 the assembly output. Temporary hack, will be corrected later,
4646 because gplink yet does not support stack and SDCC does not
4647 yet support a type of crt0.o object to create the final binary.
4649 * Removed many lines that contain 8051 legacy code.
4650 * The code is finally placed under a 'code' directive.
4651 * Added port specific options.
4653 * _process_pragma: simplified since now we do not need *special*
4654 include file to define SFR registers. But a separate header
4655 will be needed. This will be developed later.
4656 * _pic16_parseOptions: added, parses port specific options:
4657 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4658 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4659 --preplace-udata-with=
4661 * _pic16_setDefaultOptions: modified to initialize section names,
4662 but hack is temporarly out of order since it needs improvement.
4663 * _pic16_genAssemblerPreamble: configuration words are emitted by
4664 their address instead of their name. This part is incomplete and
4665 supports only the 18Fxx2 devices. Other devices will emit an error
4666 during assembly since they do not contain the same set of config
4668 * _pic16_genIVT: is modified,
4670 * pcode.c: added definitions for some hardware registers that are needed
4672 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4673 All PCI entries are updated. Now LFSR is supported.
4674 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4675 * added pic16_newpCodeOpLit2 to support instructions with
4676 two literal arguments
4677 * pic16_pCode2str: corrected code that emits assembler instructions
4678 with two literal operands and those that have an access bit modifier
4679 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4680 this fixes a bug which caused some labels to be lost, when an
4681 assembler directive was added, i.e. banksel,
4682 * pic16_FixRegisterBanking: improved logic that causes the insertion
4684 * InlineFunction: functions that are called once, are not any more
4685 inlined. This can be a port option in the future,
4687 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4689 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4690 hold the corresponding uninitialized symbols,
4691 * pic16_allocProcessorRegister: registers have explicit marked the
4693 * pic16_allocInternalRegister: registers are explicit marked as
4695 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4696 processing list, so bit registers were lost,
4699 * ralloc.h: added field 'accessBank' and original symbol operand
4700 in register definition,
4701 * removed the field isMapped from register definition,
4703 ** Several functions have been removed from various sources:
4704 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4705 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4706 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4707 pic16_assignRelocatableRegisters
4709 ** others have been introduced:
4710 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4711 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4713 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4715 * support/scripts/inc2h.pl: changed definition of BIT_AT
4716 to emit 'sbit at' instead of 'bit at'. This was a request.
4718 PIC16 port related preliminary changes:
4719 * gen.c: prefixed function popRegFromString with
4720 pic16_ and all references to it corrected
4721 * pcode.c: all pic16_pc_* hardware registers prefixed
4722 with underscore (_),
4723 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4724 * ralloc.c: newReg(): when register is REG_SFR then
4725 set address to rIdx,
4726 pic16_allocProcessorRegister(): marks register wasUsed=0
4727 pic16_writeUsedRegs(): added a call to assign processor
4728 registers via pic16_assignFixedRegisters
4730 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4732 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4733 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4734 variables in unused register banks. Also the SSEG is placed
4735 wherever there is enough space for it, and IDATA can be anywhere
4736 in internal RAM. For now compile using -Wl-Y[stack_size].
4737 The mem file is different for this option as well, since it
4738 makes no sense of talking about DSEG lenght.
4740 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4742 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4743 in certain cases, e.g. when ROM assignment, patch provided
4744 from Albert den Haan.
4746 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5632 support for standard C idiom of memory mapped variables; for
5633 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5634 to xdata int at 0x1234 tempvar = 1.
5635 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

5748 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5749 fetching of the pointer
5750 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5751 copied from genNearPointerSet()
5752 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5753 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5767 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5769 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5770 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5771 type for bits was changed. It resulted in bit variables becoming
5772 global, which is not permitted in PIC 14 assembly output.
5774 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5789 A few small changes that speed up the peephole optimizer.
5793 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5795 Try to make the peephole optimizer smarter by maintaining
5796 an association between the assembly source code and the
5797 iCodes that originated them. Put this information to use
5798 with a new peephole rule condition "notVolatile" so that
5799 the rules can be aggressive yet still safe.
5804 * src/mcs51/peeph.def
5806 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5810 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5811 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5812 if the left or right operand symbols have the accuse flag set.
5814 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5816 Changed the type of the result of the ! (NOT) operator to char;
5817 previously it returned the same type as the source. This allows
5818 us to eliminate all the genFloatNot functions (all of its target
5819 implementations were very buggy) since !float can use the same
5822 * src/SDCCicode.c (ast2iCode): ! returns char

5831 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5832 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5833 during interrupts. Ensure WSAVE is located at a shared bank address.
5834 2. Fixed page selection in some places
5835 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5836 the registers name strings.
5837 4. Fixed "signed / unsigned compare" compiler warnings.
5838 5. The PIC port manages its own allocation of the general purpose
5839 registers, but makes no attempt to reuse them. As a result when
5840 compiling it soon runs out of general purpose registers. Some
5841 additional code was added to the files pcode.c and device.c to walk
5842 through the function call tree and rename the registers so that they
5852 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5853 genPlus() & genMinus() when the result is the same as left or right

5859 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5861 Made bitfield a distinct type from bit so that bitfields
5862 convert as per ANSI C and bits retain their traditional
5863 boolean style behaviour. Implemented bitfield support in
5871 * src/ds390/gen.c: bit v bitfield split
5872 * src/z80/gen.c: New support for bitfields
5873 * support/regression/tests/bitfields.c: reenabled z80,
5876 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5878 Rules 246.x, 247.x relate to bitfields, the others speed up
5879 access to xdata mapped I/O devices.
5881 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5883 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5885 Cleaned up genPackBits and genUnpackBits and added two helper
5886 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5887 for literal assignments in genPackBits (thanks to Frieder for
5893 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5895 Fixed bug #748310 (pointer to function type mishandled when the
5896 function name is omitted). Also fixed a SIGSEGV when a function
5897 attribute (reentrant, etc) is used on a non-function or on a
5898 function but misplaced before the parameter list.
5900 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5902 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5903 * support/Util/SDCCerr.h,

5925 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5927 Made the constant following the "interrupt" keyword optional. If
5928 omitted, the function will not automatically be given an entry
5929 in the interrupt vector table (similar to #pragma NOIV, but
5930 less syntacticly kludgy). The interrupt number is also now
5931 range checked. Also fixed a bug in the high order bit example

5947 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5949 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can

6461 added if/endif conditional macros to remove options help
6462 messages from optionsTable when a port is not configured, added
6463 support for the PIc16 port in the ports table, when executing
6464 the compiler with no port specified on command line, a default
6465 port is selected with the new macro DEFAULT_PORT which is
6466 defined in port.h, in setDefaultOptions() linkOptions is removed
6467 from initialization assignment, since now it is a set,
6468 parseCmdLine uses setParseWithComma for linkOptions, in
6469 linkEdit() linkOptions are accessed with new function indexSet()
6470 which returns the i'th item of a set variable. See SDCCset.c, in
6471 linkEdit() when calling buildCmdLine(), added linkOptions as
6472 last argument. Now users can pass arguments to gplink via the
6473 -Wl option, main() uses pic16glue() to glue up pic16 programs

6486 * src/pic16/main.c: __config directives are commented out to stop
6487 gpasm complaining and test the linkage with gplink, _linkCmd and
6488 _asmCmd changed to be more gplink and gpasm friendly
6489 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6490 produced an error when parsed, peep rule 12 is added to utilize
6491 movff, but it is commented out since the pCode does not support
6492 yet a command with 2 address arguments
6494 2003-05-18 <johan AT balder>
6496 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6515 Fixed so you can set breakpoints prior to run, run does not stop
6516 on entry now. Add tbreak. Other enhancements and fixes for use
6519 2003-05-12 Borut Razem <borut.razem AT siol.net>
6521 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6523 2003-05-11 Borut Razem <borut.razem AT siol.net>
6525 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7537 2003-01-04 <johan AT balder>
7539 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7541 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7554 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7555 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7557 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7559 * in \sdcc\as\mcs51\ changed these files in order to create an
7560 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7561 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7562 following files to include the previous two files: aslink.dsp,
7563 Makefile.aslink, Makefile.bcc, and Makefile.in.
7565 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7566 .adb instead of .cdb
7568 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7570 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7571 value from option --iram-size.
7573 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7575 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7578 2002-09-18 <wiml AT hhhh.org>
7580 * SDCClrange.h: exposed setFromRange() and setToRange()
7581 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7582 packRegsForAccUse() (bug 542397)
7583 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7584 multiple times and emitting the fetch operations more than once
7585 added aopGetUsesAcc() function to allow binary operators to
7586 fetch their operands in the correct order; made genMinus() emit
7587 compact code for X = LITERAL - Y
7589 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7590 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7591 sprintf() in line 1267.
7593 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7594 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7597 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7598 Changes to aslink (All the changes are marked with 'JCF'):
7600 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7603 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7604 area BSEG. Also moves, if possible, the DATA area down into the internal
7605 ram so more space is available.
7607 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7610 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7611 not bytes. Function summary() which creates a memory usage summary
7612 file with extension .mem. Reports of overlaping stack and small stack
7613 size. If the space for the stack is less than 16 bytes aslink trows a
7616 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7617 the 8051. Option 'y' for memory summary output file.
7619 Changes to sdcc (All the changes are marked with 'JCF'):
7621 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7623 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7624 overlaying area for it (uses RegBankUsed[4]).
7626 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7627 bank zero as used by default. By default aslink locates the stack
7628 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7629 the creation of the .mem file. Delegates the allocation of data area
7630 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7631 the begining of the stack area to aslink.
7633 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7634 glue() in SDCCglue.c creates an area for it.
7636 2002-09-03 Borut Razem <borut.razem AT siol.net>
7637 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7638 sdcc/src/pic/glue.c:
7639 introduced atexit() handler for teporay files removal in case of
7640 errors, assertions, ...
7642 2002-08-29 Borut Razem <borut.razem AT siol.net>
7643 * sdcc/support/cpp2/auto-host_vc_in.h:
7644 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7645 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7646 Maybe there is a similar problem with BORLANDC? It should be checked!
7648 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7649 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7650 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7651 was not executed, and the compiler (cl) launched a warning:
7652 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7654 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7655 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7657 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7658 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7660 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7661 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7662 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7663 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7664 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7665 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7666 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7667 - added Release configuration in VS projects
7668 - review of compiler an linker options
7669 - VC .exe files are generated in bin_vc directory, not to interfere
7670 with binaries generated from other projects (cygwin, mingw, bcc ...)
7672 * sdcc/src/yacc.dsp: added
7674 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7675 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7676 and insert the version number definitions from .version
7678 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7680 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7681 added - genarate auto-host.h using auto-host_vc_in.h as template
7684 removed from CVS, generated automatically
7686 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7687 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7689 2002-08-11 Borut Razem <borut.razem AT siol.net>
7690 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7692 2002-08-10 Borut Razem <borut.razem AT siol.net>
7693 * src/SDCCmain.c (main):
7694 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7695 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7696 The consequence was that some temporary files were not removed.
7699 unification of code in functions tempfilename() and tempfile():
7700 function tempnam() is defined in Visual Studio 6.0 and .NET
7702 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7704 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7705 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7706 - removed compiler command line option /WX: Treats all warnings as errors
7707 - update a list of source files, included into the project
7709 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7710 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7711 changed project type to Generic Project so that can be correcly converted to VS.NET project
7713 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7715 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7717 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7719 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7720 added return 0 statements after assert() to make compiler happy
7722 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7723 added newline in the def file to keep MSC compiler satisfied
7725 * sdcc/src/z80/gen.c:
7726 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7727 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7728 - solved MSC error in function aopDump()
7730 * sdcc_vc.h: define PREFIX as "\\sdcc"
7732 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7733 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7736 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7737 - Rewrote the register banking algorithm.
7738 - Added pCode live-range analysis to registers (for now, only non-used and
7739 singly-used registers optimized away)
7741 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

7776 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7778 Added "char *Processor" field to the port structure.
7781 Added -p option. Allows port dependent processor to be specified.
7784 Initialized the new field char *Processor field to NULL in all ports
7787 Compiler generated registers for interrupt context saving
7788 were not getting allocated.
7790 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7793 Fixed left shift. Will promote the left side of a left shift
7794 if a) left shifting more than size of operand or b) when assigned
7795 to something size > size of left side
7797 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7799 tons of changes. Register allocation has been
7800 rewritten. Added customization for the various PICs. Flow

7908 Previous fix was not good. basic blocks that have "break" or "return" are
7909 not really partof a loop , but live ranges used in these blocks should
7910 be live thru the entire loop, so set partOfLoop but don't add them to
