113 Adding support for replacing ljmps with sjmps in jumptables
114 generated for switch statements. For now you need to set the
115 environment variable SDCC_SJMP_JUMPTABLE to enable this.
116 Now 4 algorithms for mcs51 jumptable generation are used:
117 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

148 * (malloc.h): added CVS Id tag,
149 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
151 * added libc directory. The current version of LibC contains string
152 functions, ctype functions and macros and some functions of the
153 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
154 be extensively tested in the future. Standard disclaimer here.
155 Library is not automatically build yet. But one can build it by
156 invoking 'make' inside the libc directory.

169 special compare&skip instructions. Initial tests fail some times
170 with variables grater than 1 byte in size, so new code is disabled,
171 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
173 * (genCast): began a fix to optimize the casting of a bit to another
174 bit, now assigning a bitfield to another bitfield will fail, sorry,

3149 * src/pic/ralloc.h: applied patch from Slade Rich;
3150 added support for multiple code pages and multiple RAM banks on the
3151 PIC 14 port. The ASM files now no longer simply assume all the
3152 code / RAM are in the same page / bank. This means the linker can
3153 safely allocate code/RAM of separate ASM files to different pages/banks.
3154 * doc/sdccman.lyx: added Slade's tips
3155 * src/mcs51/peeph.def: fixed bug #880768

3164 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3167 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3168 strtof is not part of C89 and isn't included with Mac OS X.
3170 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3172 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
3173 shiftL2Left2Result): fixed bug #879326
3174 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

3197 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3199 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3200 loaded with the linker search paths (-L arguments) and the libraries
3201 to be linked with the current source (-l arguments). Changes
3202 currently will affect only the pic16 port.
3203 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3204 include path the port specific paths and port specific libraries,
3205 * gplink command now contains the $3 argument,
3206 * src/pic16/device.h,
3207 * src/pic16/device.c,: structure PIC_device is made public and
3208 renamed to PIC16_device, the same for variable Pics which is renamed
3209 to Pics16. Updated all references to them.
3210 * src/pic16/glue.c (pic16glue): corrected bug with code
3211 initialization which bypassed the variable initializations block.

3221 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3223 Documenting changes from previous commits.
3224 * configure.in (version 1.56),
3225 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3226 when generating output files to configure the pic16 library,
3227 but now I've commented it out, since gputils aren't installed in the
3228 SF compile farm, so library won't compile
3230 * device/lib/Makefile.in (version 1.56): initially I've added in
3231 target 'all' the prerequestive 'model-pic16' so it compiled the
3232 pic16 library, but now I've commented it out for the same reasons
3234 * added targets 'model-pic16' and 'objects-pic16' to compile the
3236 * added target 'port-specific-objects-pic16' to handle the
3237 generated libraries and copy them into the build/ directory
3238 * added target 'clean-intermediate-pic16' to clean intermediate
3239 files into pic16 directory
3240 * in target 'installdirs' added line to create directory pic16 in
3241 the installation path
3243 * device/include/Makefile.in (version 1.11): in target 'install'
3244 added lines to copy all header files to installation path,
3245 * in target 'installdirs' added line create directory for pic16
3246 headers in the installation path

3261 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3262 option so that it actually works. Made it specific to the z80, since
3263 the gbz80 doesn't have these kinds of I/O ports.
3265 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3267 * device/include/z180.h,

3289 Mainly changes to support compilation of the device libraries
3290 * src/pic16/device.c: stack is allocated via symbol and not
3291 via literal number. The symbol is placed in the corresponding
3292 position of the data ram
3293 * (pic16_dump_section): relocatable and absolute uninitialized
3294 data are now emitted in sorted order to reduce section naming,
3295 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3296 weren't marked as being in the access bank,
3298 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3300 Added portion of GNU PIC Library under the directory
3301 device/include/pic16 and device/lib/pic16. These files
3302 contain the declarations of SFRs for the PIC18Fxx2 devices.
3303 The directory is initialized via configure from toplevel.
3305 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3307 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3308 the spilllocations to be compared correctly

3333 all over. Telling LaTeX to be less strict with word spacing
3334 to better keep the right margin. Changed some notes about
3335 maintainance of the ports in section 3.2.1 - is it OK like this?
3337 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3375 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3377 * src/pic16/peeph.def: all peepholes with movff are commented out,
3378 because there is a problem in the pcode peep optimizer,
3379 * src/pic16/ralloc.c: the register allocator can now reuse local

3499 * support/valdiag/Makefile,
3500 * support/valdiag/valdiag.py,
3501 * support/valdiag/tests/*

3531 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3533 PIC16 port related changes:
3534 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3535 added variable stackPos,
3537 * gen.c: genCall, assignResultValue: added support for
3538 pushing/retrieving function parameters to/from stack,
3539 genFunction,genEndFunction: setup stack frame for the
3541 genAddrOf: will be changed according to bug 863624
3543 * added files genutils.c and genutils.h which contain gen*
3544 debugged and optimised functions extracted from gen.c
3546 * glue.c: added variable 'externs' which holds extern symbols,
3547 pic16emitRegularMap: is modified to properly handle relocatable
3548 symbols under the new scheme,
3549 pic16createInterruptVect: is modified
3550 pic16printPublics: is modified to emit 'global' assembler directives,
3551 added pic16_printExterns to print extern symbols,
3552 pic16glue: initializes stack/frame pointer in the beginning of
3553 the assembly output. Temporary hack, will be corrected later,
3554 because gplink yet does not support stack and SDCC does not
3555 yet support a type of crt0.o object to create the final binary.
3557 * Removed many lines that contain 8051 legacy code.
3558 * The code is finally placed under a 'code' directive.
3559 * Added port specific options.
3561 * _process_pragma: simplified since now we do not need *special*
3562 include file to define SFR registers. But a separate header
3563 will be needed. This will be developed later.
3564 * _pic16_parseOptions: added, parses port specific options:
3565 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3566 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3567 --preplace-udata-with=
3569 * _pic16_setDefaultOptions: modified to initialize section names,
3570 but hack is temporarly out of order since it needs improvement.
3571 * _pic16_genAssemblerPreamble: configuration words are emitted by
3572 their address instead of their name. This part is incomplete and
3573 supports only the 18Fxx2 devices. Other devices will emit an error
3574 during assembly since they do not contain the same set of config
3576 * _pic16_genIVT: is modified,
3578 * pcode.c: added definitions for some hardware registers that are needed
3580 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3581 All PCI entries are updated. Now LFSR is supported.
3582 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3583 * added pic16_newpCodeOpLit2 to support instructions with
3584 two literal arguments
3585 * pic16_pCode2str: corrected code that emits assembler instructions
3586 with two literal operands and those that have an access bit modifier
3587 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3588 this fixes a bug which caused some labels to be lost, when an
3589 assembler directive was added, i.e. banksel,
3590 * pic16_FixRegisterBanking: improved logic that causes the insertion
3592 * InlineFunction: functions that are called once, are not any more
3593 inlined. This can be a port option in the future,
3595 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3597 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3598 hold the corresponding uninitialized symbols,
3599 * pic16_allocProcessorRegister: registers have explicit marked the
3601 * pic16_allocInternalRegister: registers are explicit marked as
3603 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3604 processing list, so bit registers were lost,
3607 * ralloc.h: added field 'accessBank' and original symbol operand
3608 in register definition,
3609 * removed the field isMapped from register definition,
3611 ** Several functions have been removed from various sources:
3612 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3613 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3614 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3615 pic16_assignRelocatableRegisters
3617 ** others have been introduced:
3618 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3619 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3621 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3623 * support/scripts/inc2h.pl: changed definition of BIT_AT
3624 to emit 'sbit at' instead of 'bit at'. This was a request.
3626 PIC16 port related preliminary changes:
3627 * gen.c: prefixed function popRegFromString with
3628 pic16_ and all references to it corrected
3629 * pcode.c: all pic16_pc_* hardware registers prefixed
3630 with underscore (_),
3631 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3632 * ralloc.c: newReg(): when register is REG_SFR then
3633 set address to rIdx,
3634 pic16_allocProcessorRegister(): marks register wasUsed=0
3635 pic16_writeUsedRegs(): added a call to assign processor
3636 registers via pic16_assignFixedRegisters
3638 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3640 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3641 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3642 variables in unused register banks. Also the SSEG is placed
3643 wherever there is enough space for it, and IDATA can be anywhere
3644 in internal RAM. For now compile using -Wl-Y[stack_size].
3645 The mem file is different for this option as well, since it
3646 makes no sense of talking about DSEG lenght.
3648 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3650 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4641 and JUMPTABLE iCodes properly now (worked by accident before)
4642 * src/mcs51/gen.c (leftRightUseAcc),
4643 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
4644 iCode properly now. Use getSize instead of nRegs since a & b
4645 aren't part of the nRegs tally.
4647 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4649 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

4655 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4656 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4657 fetching of the pointer
4658 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4659 copied from genNearPointerSet()
4660 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4661 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4662 If they pop r0/r1 they must be called in the opposite order than aopOp().
4663 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4664 (resp. --stack-auto), prepared for --xstack

4675 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4677 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4678 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4679 type for bits was changed. It resulted in bit variables becoming
4680 global, which is not permitted in PIC 14 assembly output.
4682 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4684 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4697 A few small changes that speed up the peephole optimizer.
4701 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4703 Try to make the peephole optimizer smarter by maintaining
4704 an association between the assembly source code and the
4705 iCodes that originated them. Put this information to use
4706 with a new peephole rule condition "notVolatile" so that
4707 the rules can be aggressive yet still safe.
4712 * src/mcs51/peeph.def
4714 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4718 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4719 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4720 if the left or right operand symbols have the accuse flag set.
4722 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4724 Changed the type of the result of the ! (NOT) operator to char;
4725 previously it returned the same type as the source. This allows
4726 us to eliminate all the genFloatNot functions (all of its target
4727 implementations were very buggy) since !float can use the same
4730 * src/SDCCicode.c (ast2iCode): ! returns char

4732 * src/ds390/gen.c (genNot, genNotFloat),
4733 * src/z80/gen.c (genNot, genNotFloat),
4734 * src/pic/gen.c (genNot, genNotFloat),

4739 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4740 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4741 during interrupts. Ensure WSAVE is located at a shared bank address.
4742 2. Fixed page selection in some places
4743 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4744 the registers name strings.
4745 4. Fixed "signed / unsigned compare" compiler warnings.
4746 5. The PIC port manages its own allocation of the general purpose
4747 registers, but makes no attempt to reuse them. As a result when
4748 compiling it soon runs out of general purpose registers. Some
4749 additional code was added to the files pcode.c and device.c to walk
4750 through the function call tree and rename the registers so that they
4760 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4767 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4769 Made bitfield a distinct type from bit so that bitfields
4770 convert as per ANSI C and bits retain their traditional
4771 boolean style behaviour. Implemented bitfield support in
4779 * src/ds390/gen.c: bit v bitfield split
4780 * src/z80/gen.c: New support for bitfields
4781 * support/regression/tests/bitfields.c: reenabled z80,
4784 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4786 Rules 246.x, 247.x relate to bitfields, the others speed up
4787 access to xdata mapped I/O devices.
4789 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4791 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4793 Cleaned up genPackBits and genUnpackBits and added two helper
4794 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4795 for literal assignments in genPackBits (thanks to Frieder for
4801 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4803 Fixed bug #748310 (pointer to function type mishandled when the
4804 function name is omitted). Also fixed a SIGSEGV when a function
4805 attribute (reentrant, etc) is used on a non-function or on a
4806 function but misplaced before the parameter list.
4808 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4810 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4811 * support/Util/SDCCerr.h,

4833 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4835 Made the constant following the "interrupt" keyword optional. If
4836 omitted, the function will not automatically be given an entry
4837 in the interrupt vector table (similar to #pragma NOIV, but
4838 less syntacticly kludgy). The interrupt number is also now
4839 range checked. Also fixed a bug in the high order bit example

4860 unsigned, but are signed by default
4861 * src/SDCCval.c (constVal): rearranged
4862 * src/SDCCval.c (valMod): preliminary fix
4863 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5315 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5316 the regression tests I'm not brave enough to enable 245.b, 245.c
5317 * doc/sdccman.lyx: added latex preamble for hyperref package.
5318 Using pdflatex this will give you a hyperlinked pdf file with
5319 bookmarks. (prepend '%' before /usepackage if this breaks something)

5357 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5359 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5360 it can be defined with CFLAGS when running configure
5361 * src/SDCCmain.c: fixed compiling + linking with object files
5363 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5366 added --disable-pic16-port
5367 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5368 * src/SDCCmain.c: linkOptions is changed to set *,
5369 added if/endif conditional macros to remove options help
5370 messages from optionsTable when a port is not configured, added
5371 support for the PIc16 port in the ports table, when executing
5372 the compiler with no port specified on command line, a default
5373 port is selected with the new macro DEFAULT_PORT which is
5374 defined in port.h, in setDefaultOptions() linkOptions is removed
5375 from initialization assignment, since now it is a set,
5376 parseCmdLine uses setParseWithComma for linkOptions, in
5377 linkEdit() linkOptions are accessed with new function indexSet()
5378 which returns the i'th item of a set variable. See SDCCset.c, in
5379 linkEdit() when calling buildCmdLine(), added linkOptions as
5380 last argument. Now users can pass arguments to gplink via the
5381 -Wl option, main() uses pic16glue() to glue up pic16 programs
5382 * src/SDCCpeeph.c: various changes to support pic16

5391 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
5393 * src/pic16/glue.c: commented out some error producing lines
5394 * src/pic16/main.c: __config directives are commented out to stop
5395 gpasm complaining and test the linkage with gplink, _linkCmd and
5396 _asmCmd changed to be more gplink and gpasm friendly
5397 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5398 produced an error when parsed, peep rule 12 is added to utilize
5399 movff, but it is commented out since the pCode does not support
5400 yet a command with 2 address arguments
5402 2003-05-18 <johan AT balder>
5404 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5405 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5431 2003-05-11 Borut Razem <borut.razem AT siol.net>
5433 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5434 the path of bin directory, so that PATH is the only env. variable, which has to be set
5435 in case of standard installation.
5436 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6468 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6469 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6470 following files to include the previous two files: aslink.dsp,
6471 Makefile.aslink, Makefile.bcc, and Makefile.in.
6473 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6474 .adb instead of .cdb
6476 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6478 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6479 value from option --iram-size.
6481 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6483 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6486 2002-09-18 <wiml AT hhhh.org>
6488 * SDCClrange.h: exposed setFromRange() and setToRange()
6489 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6490 packRegsForAccUse() (bug 542397)
6491 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6492 multiple times and emitting the fetch operations more than once
6493 added aopGetUsesAcc() function to allow binary operators to
6494 fetch their operands in the correct order; made genMinus() emit
6495 compact code for X = LITERAL - Y
6497 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6498 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6499 sprintf() in line 1267.
6501 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6502 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6505 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6506 Changes to aslink (All the changes are marked with 'JCF'):
6508 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6511 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6512 area BSEG. Also moves, if possible, the DATA area down into the internal
6513 ram so more space is available.
6515 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6518 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6519 not bytes. Function summary() which creates a memory usage summary
6520 file with extension .mem. Reports of overlaping stack and small stack
6521 size. If the space for the stack is less than 16 bytes aslink trows a
6524 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6525 the 8051. Option 'y' for memory summary output file.
6527 Changes to sdcc (All the changes are marked with 'JCF'):
6529 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6531 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6532 overlaying area for it (uses RegBankUsed[4]).
6534 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6535 bank zero as used by default. By default aslink locates the stack
6536 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6537 the creation of the .mem file. Delegates the allocation of data area
6538 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6539 the begining of the stack area to aslink.
6541 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6542 glue() in SDCCglue.c creates an area for it.
6544 2002-09-03 Borut Razem <borut.razem AT siol.net>
6545 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6546 sdcc/src/pic/glue.c:
6547 introduced atexit() handler for teporay files removal in case of
6548 errors, assertions, ...
6550 2002-08-29 Borut Razem <borut.razem AT siol.net>
6551 * sdcc/support/cpp2/auto-host_vc_in.h:
6552 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6553 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6554 Maybe there is a similar problem with BORLANDC? It should be checked!
6556 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6557 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6558 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6559 was not executed, and the compiler (cl) launched a warning:
6560 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6562 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6563 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6565 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6566 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6568 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6569 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6570 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6571 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6572 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6573 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6574 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6575 - added Release configuration in VS projects
6576 - review of compiler an linker options
6577 - VC .exe files are generated in bin_vc directory, not to interfere
6578 with binaries generated from other projects (cygwin, mingw, bcc ...)
6580 * sdcc/src/yacc.dsp: added
6582 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6583 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6584 and insert the version number definitions from .version
6586 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6588 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6589 added - genarate auto-host.h using auto-host_vc_in.h as template
6592 removed from CVS, generated automatically
6594 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>

6597 2002-08-11 Borut Razem <borut.razem AT siol.net>
6598 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6600 2002-08-10 Borut Razem <borut.razem AT siol.net>
6601 * src/SDCCmain.c (main):
6602 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6603 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6604 The consequence was that some temporary files were not removed.
6607 unification of code in functions tempfilename() and tempfile():
6608 function tempnam() is defined in Visual Studio 6.0 and .NET
6610 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6612 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6613 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6614 - removed compiler command line option /WX: Treats all warnings as errors
6615 - update a list of source files, included into the project
6617 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6618 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6619 changed project type to Generic Project so that can be correcly converted to VS.NET project
6621 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6623 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6625 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6627 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6628 added return 0 statements after assert() to make compiler happy
6630 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6631 added newline in the def file to keep MSC compiler satisfied
6633 * sdcc/src/z80/gen.c:
6634 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6635 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6636 - solved MSC error in function aopDump()
6638 * sdcc_vc.h: define PREFIX as "\\sdcc"
6640 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6641 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6689 Added -p option. Allows port dependent processor to be specified.
6692 Initialized the new field char *Processor field to NULL in all ports
6695 Compiler generated registers for interrupt context saving
6696 were not getting allocated.
6698 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6701 Fixed left shift. Will promote the left side of a left shift
6702 if a) left shifting more than size of operand or b) when assigned
6703 to something size > size of left side
6705 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6707 tons of changes. Register allocation has been

6813 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6815 * sdcc/src/SDCCloop.c:
6816 Previous fix was not good. basic blocks that have "break" or "return" are
6817 not really partof a loop , but live ranges used in these blocks should
6818 be live thru the entire loop, so set partOfLoop but don't add them to
6821 2002-02-21 <johan AT FRIJA>
6823 * src/SDCCcse.c: fixed bug #514308
6825 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

6831 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6833 2002-02-10 Karl Bongers <karl AT turbobit.com>

6844 for use as a multiple module SDCDB test case.
6846 * sim/ucsim/cmd.src/cmdset.cc:
6847 Took out debug printfs in ucsim "next" command.
6850 Karl and Johan start ucsim XA support. Most dissassembly working,
6851 about 75% emulation done(plenty of work remaining).
6853 * sim/ucsim/z80.src:
6854 Add Z80 support to ucsim, add test-ucz80 regression test,
6855 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
