39 Adding support for replacing ljmps with sjmps in jumptables
40 generated for switch statements. For now you need to set the
41 environment variable SDCC_SJMP_JUMPTABLE to enable this.
42 Now 4 algorithms for mcs51 jumptable generation are used:
43 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
44 addresses loaded pc-relative for up to 112 cases and stack-pushing
45 target addresses loaded with offset from dptr for up to 256 cases.

71 Large cummulative patch for pic16 port.
72 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
73 to call when a stack overflow occurs,
74 * (malloc.h): added CVS Id tag,
75 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
77 * added libc directory. The current version of LibC contains string
78 functions, ctype functions and macros and some functions of the
79 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
80 be extensively tested in the future. Standard disclaimer here.
81 Library is not automatically build yet. But one can build it by
82 invoking 'make' inside the libc directory.
83 * added ADC library under libio. Preliminary version yet.

93 * (pic16_storeForReturn): optimized return of 0,
94 * (genCmp): experimental code for new genCmp which uses PIC18's
95 special compare&skip instructions. Initial tests fail some times
96 with variables grater than 1 byte in size, so new code is disabled,
97 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
99 * (genCast): began a fix to optimize the casting of a bit to another
100 bit, now assigning a bitfield to another bitfield will fail, sorry,
101 * src/pic16/main.c: disabled the use of lr-support feature,
102 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
103 * added some function prototypes, added function _debugf prototype,

105 bits with offset (case PO_GPR_BIT),
106 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
108 * (isBankInstruction): modified to return 0 for no banking instruction,
109 and 1 for banking instruction,
110 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
111 caused stop processing pCodes after a inline assembly block,
112 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
113 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
114 registers when it shouldn't,
115 * src/pic16/ralloc.c (allocReg): add preliminary support for
116 supporting a limited set of temporary registers,
118 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
120 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

123 (loadRegFromAop): recognize CLRH optimization,
124 (genFunction): optimize RECEIVE iCodes in reentrant functions
126 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
128 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3123 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3125 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3126 loaded with the linker search paths (-L arguments) and the libraries
3127 to be linked with the current source (-l arguments). Changes
3128 currently will affect only the pic16 port.
3129 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3130 include path the port specific paths and port specific libraries,
3131 * gplink command now contains the $3 argument,
3132 * src/pic16/device.h,
3133 * src/pic16/device.c,: structure PIC_device is made public and
3134 renamed to PIC16_device, the same for variable Pics which is renamed

3149 Documenting changes from previous commits.
3150 * configure.in (version 1.56),
3151 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3152 when generating output files to configure the pic16 library,
3153 but now I've commented it out, since gputils aren't installed in the
3154 SF compile farm, so library won't compile
3156 * device/lib/Makefile.in (version 1.56): initially I've added in
3157 target 'all' the prerequestive 'model-pic16' so it compiled the
3158 pic16 library, but now I've commented it out for the same reasons
3160 * added targets 'model-pic16' and 'objects-pic16' to compile the
3162 * added target 'port-specific-objects-pic16' to handle the
3163 generated libraries and copy them into the build/ directory
3164 * added target 'clean-intermediate-pic16' to clean intermediate
3165 files into pic16 directory

3187 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3188 option so that it actually works. Made it specific to the z80, since
3189 the gbz80 doesn't have these kinds of I/O ports.

3217 via literal number. The symbol is placed in the corresponding
3218 position of the data ram
3219 * (pic16_dump_section): relocatable and absolute uninitialized
3220 data are now emitted in sorted order to reduce section naming,
3221 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3222 weren't marked as being in the access bank,
3224 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3226 Added portion of GNU PIC Library under the directory
3227 device/include/pic16 and device/lib/pic16. These files
3228 contain the declarations of SFRs for the PIC18Fxx2 devices.
3229 The directory is initialized via configure from toplevel.
3231 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3233 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3259 all over. Telling LaTeX to be less strict with word spacing
3260 to better keep the right margin. Changed some notes about
3261 maintainance of the ports in section 3.2.1 - is it OK like this?
3263 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3301 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3303 * src/pic16/peeph.def: all peepholes with movff are commented out,
3304 because there is a problem in the pcode peep optimizer,
3305 * src/pic16/ralloc.c: the register allocator can now reuse local

3307 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3309 Added file src/pic16/NOTES with information about program writing on
3310 the current port version.

3342 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3345 * src/z80/main.c: added missed needLinkerScript flags (more than
3346 one port structure defined in these file)
3347 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3369 * (pic14emitOverlay): modified to emit a commented overlay segment
3370 directive when no overlay data exist
3371 * (picglue): modified to emit uninitialized data segment
3372 according to udata_section_name

3392 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3394 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3396 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

3398 include information about variables allocated to the overlay
3401 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3403 * as/mcs51/lkmain.c: Help about -Y option

3415 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3417 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3418 (default behaviour).
3420 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3422 A python script to validate compiler diagnostic messages. It can be
3423 used to verify that sdcc complains about bad c source code and
3424 gives a good location of the error.
3425 * support/valdiag/Makefile,
3426 * support/valdiag/valdiag.py,
3427 * support/valdiag/tests/*
3429 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3442 * src/common.h: added ifndef/define/endif macros
3443 around the header file.
3444 Bug reported from Jesus Calvino-Fraga
3446 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3448 * sdcc.spec: updated
3449 * device/include/Makefile.in: don't install CVS directories
3450 * device/lib/Makefile.in: added removal of CVS directories after install
3451 * doc/Makefile: fixed install, added local_icons
3452 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3453 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3454 * src/ds390/gen.c (genRightShift): fixed bug #870788
3455 * src/SDCCast.c (decorateType): fixed bug #870781
3457 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3459 PIC16 port related changes:
3460 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3461 added variable stackPos,
3463 * gen.c: genCall, assignResultValue: added support for
3464 pushing/retrieving function parameters to/from stack,
3465 genFunction,genEndFunction: setup stack frame for the
3467 genAddrOf: will be changed according to bug 863624
3469 * added files genutils.c and genutils.h which contain gen*
3470 debugged and optimised functions extracted from gen.c
3472 * glue.c: added variable 'externs' which holds extern symbols,
3473 pic16emitRegularMap: is modified to properly handle relocatable
3474 symbols under the new scheme,
3475 pic16createInterruptVect: is modified
3476 pic16printPublics: is modified to emit 'global' assembler directives,
3477 added pic16_printExterns to print extern symbols,
3478 pic16glue: initializes stack/frame pointer in the beginning of
3479 the assembly output. Temporary hack, will be corrected later,
3480 because gplink yet does not support stack and SDCC does not
3481 yet support a type of crt0.o object to create the final binary.
3483 * Removed many lines that contain 8051 legacy code.
3484 * The code is finally placed under a 'code' directive.
3485 * Added port specific options.
3487 * _process_pragma: simplified since now we do not need *special*
3488 include file to define SFR registers. But a separate header
3489 will be needed. This will be developed later.
3490 * _pic16_parseOptions: added, parses port specific options:
3491 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3492 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3493 --preplace-udata-with=
3495 * _pic16_setDefaultOptions: modified to initialize section names,
3496 but hack is temporarly out of order since it needs improvement.
3497 * _pic16_genAssemblerPreamble: configuration words are emitted by
3498 their address instead of their name. This part is incomplete and
3499 supports only the 18Fxx2 devices. Other devices will emit an error
3500 during assembly since they do not contain the same set of config
3502 * _pic16_genIVT: is modified,
3504 * pcode.c: added definitions for some hardware registers that are needed
3506 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3507 All PCI entries are updated. Now LFSR is supported.
3508 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3509 * added pic16_newpCodeOpLit2 to support instructions with
3510 two literal arguments
3511 * pic16_pCode2str: corrected code that emits assembler instructions
3512 with two literal operands and those that have an access bit modifier
3513 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3514 this fixes a bug which caused some labels to be lost, when an
3515 assembler directive was added, i.e. banksel,
3516 * pic16_FixRegisterBanking: improved logic that causes the insertion
3518 * InlineFunction: functions that are called once, are not any more
3519 inlined. This can be a port option in the future,
3521 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3523 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3524 hold the corresponding uninitialized symbols,
3525 * pic16_allocProcessorRegister: registers have explicit marked the
3527 * pic16_allocInternalRegister: registers are explicit marked as
3529 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3530 processing list, so bit registers were lost,
3533 * ralloc.h: added field 'accessBank' and original symbol operand
3534 in register definition,
3535 * removed the field isMapped from register definition,
3537 ** Several functions have been removed from various sources:
3538 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3539 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3540 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3541 pic16_assignRelocatableRegisters
3543 ** others have been introduced:
3544 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3545 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3547 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3549 * support/scripts/inc2h.pl: changed definition of BIT_AT
3550 to emit 'sbit at' instead of 'bit at'. This was a request.
3552 PIC16 port related preliminary changes:
3553 * gen.c: prefixed function popRegFromString with
3554 pic16_ and all references to it corrected
3555 * pcode.c: all pic16_pc_* hardware registers prefixed
3556 with underscore (_),
3557 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3558 * ralloc.c: newReg(): when register is REG_SFR then
3559 set address to rIdx,
3560 pic16_allocProcessorRegister(): marks register wasUsed=0
3561 pic16_writeUsedRegs(): added a call to assign processor
3562 registers via pic16_assignFixedRegisters
3564 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3566 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3567 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3568 variables in unused register banks. Also the SSEG is placed
3569 wherever there is enough space for it, and IDATA can be anywhere
3570 in internal RAM. For now compile using -Wl-Y[stack_size].
3571 The mem file is different for this option as well, since it
3572 makes no sense of talking about DSEG lenght.
3574 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3576 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3577 in certain cases, e.g. when ROM assignment, patch provided
3578 from Albert den Haan.
3580 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4125 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4127 Fixed a number of problems revealed by bug #827883.
4128 * src/SDCCloop.c (loopInvariants): Spill location of the
4129 result operand should be recomputed if extracted from
4130 a loop. Also, don't extract assignments of an iTemp
4132 * src/SDCCast.c (isConformingBody): loop reversal should
4133 not occur if the control variable is involved with a
4134 relational operator.

4623 A few small changes that speed up the peephole optimizer.
4627 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4629 Try to make the peephole optimizer smarter by maintaining
4630 an association between the assembly source code and the
4631 iCodes that originated them. Put this information to use
4632 with a new peephole rule condition "notVolatile" so that
4633 the rules can be aggressive yet still safe.

4651 previously it returned the same type as the source. This allows
4652 us to eliminate all the genFloatNot functions (all of its target
4653 implementations were very buggy) since !float can use the same

4665 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4666 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4667 during interrupts. Ensure WSAVE is located at a shared bank address.
4668 2. Fixed page selection in some places
4669 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4670 the registers name strings.
4671 4. Fixed "signed / unsigned compare" compiler warnings.
4672 5. The PIC port manages its own allocation of the general purpose
4673 registers, but makes no attempt to reuse them. As a result when
4674 compiling it soon runs out of general purpose registers. Some
4675 additional code was added to the files pcode.c and device.c to walk
4676 through the function call tree and rename the registers so that they
4686 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4693 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4695 Made bitfield a distinct type from bit so that bitfields
4696 convert as per ANSI C and bits retain their traditional
4697 boolean style behaviour. Implemented bitfield support in
4705 * src/ds390/gen.c: bit v bitfield split
4706 * src/z80/gen.c: New support for bitfields

4710 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4712 Rules 246.x, 247.x relate to bitfields, the others speed up
4713 access to xdata mapped I/O devices.
4715 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4717 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4719 Cleaned up genPackBits and genUnpackBits and added two helper
4720 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4721 for literal assignments in genPackBits (thanks to Frieder for
4727 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4729 Fixed bug #748310 (pointer to function type mishandled when the
4730 function name is omitted). Also fixed a SIGSEGV when a function
4731 attribute (reentrant, etc) is used on a non-function or on a
4732 function but misplaced before the parameter list.

4761 Made the constant following the "interrupt" keyword optional. If
4762 omitted, the function will not automatically be given an entry
4763 in the interrupt vector table (similar to #pragma NOIV, but
4764 less syntacticly kludgy). The interrupt number is also now
4765 range checked. Also fixed a bug in the high order bit example

5241 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5242 the regression tests I'm not brave enough to enable 245.b, 245.c
5243 * doc/sdccman.lyx: added latex preamble for hyperref package.
5244 Using pdflatex this will give you a hyperlinked pdf file with

5286 it can be defined with CFLAGS when running configure
5287 * src/SDCCmain.c: fixed compiling + linking with object files
5289 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5292 added --disable-pic16-port
5293 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5294 * src/SDCCmain.c: linkOptions is changed to set *,
5295 added if/endif conditional macros to remove options help
5296 messages from optionsTable when a port is not configured, added
5297 support for the PIc16 port in the ports table, when executing
5298 the compiler with no port specified on command line, a default
5299 port is selected with the new macro DEFAULT_PORT which is
5300 defined in port.h, in setDefaultOptions() linkOptions is removed
5301 from initialization assignment, since now it is a set,
5302 parseCmdLine uses setParseWithComma for linkOptions, in
5303 linkEdit() linkOptions are accessed with new function indexSet()
5304 which returns the i'th item of a set variable. See SDCCset.c, in
5305 linkEdit() when calling buildCmdLine(), added linkOptions as
5306 last argument. Now users can pass arguments to gplink via the
5307 -Wl option, main() uses pic16glue() to glue up pic16 programs
5308 * src/SDCCpeeph.c: various changes to support pic16

5319 * src/pic16/glue.c: commented out some error producing lines
5320 * src/pic16/main.c: __config directives are commented out to stop
5321 gpasm complaining and test the linkage with gplink, _linkCmd and
5322 _asmCmd changed to be more gplink and gpasm friendly
5323 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5324 produced an error when parsed, peep rule 12 is added to utilize
5325 movff, but it is commented out since the pCode does not support
5326 yet a command with 2 address arguments
5328 2003-05-18 <johan AT balder>
5330 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5355 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5357 2003-05-11 Borut Razem <borut.razem AT siol.net>
5359 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5360 the path of bin directory, so that PATH is the only env. variable, which has to be set
5361 in case of standard installation.
5362 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6365 * src/SDCCicode.c: fixed array add
6367 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6368 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6369 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6371 2003-01-04 <johan AT balder>
6373 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6375 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6388 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6389 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6391 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6393 * in \sdcc\as\mcs51\ changed these files in order to create an
6394 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6395 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6396 following files to include the previous two files: aslink.dsp,
6397 Makefile.aslink, Makefile.bcc, and Makefile.in.
6399 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6400 .adb instead of .cdb
6402 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6404 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6405 value from option --iram-size.
6407 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6409 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6412 2002-09-18 <wiml AT hhhh.org>
6414 * SDCClrange.h: exposed setFromRange() and setToRange()
6415 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6416 packRegsForAccUse() (bug 542397)
6417 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6418 multiple times and emitting the fetch operations more than once
6419 added aopGetUsesAcc() function to allow binary operators to
6420 fetch their operands in the correct order; made genMinus() emit
6421 compact code for X = LITERAL - Y
6423 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6424 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6425 sprintf() in line 1267.
6427 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6428 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6431 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6432 Changes to aslink (All the changes are marked with 'JCF'):
6434 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6437 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6438 area BSEG. Also moves, if possible, the DATA area down into the internal
6439 ram so more space is available.
6441 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6444 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6445 not bytes. Function summary() which creates a memory usage summary
6446 file with extension .mem. Reports of overlaping stack and small stack
6447 size. If the space for the stack is less than 16 bytes aslink trows a
6450 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6451 the 8051. Option 'y' for memory summary output file.
6453 Changes to sdcc (All the changes are marked with 'JCF'):
6455 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6457 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6458 overlaying area for it (uses RegBankUsed[4]).
6460 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6461 bank zero as used by default. By default aslink locates the stack
6462 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6463 the creation of the .mem file. Delegates the allocation of data area
6464 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6465 the begining of the stack area to aslink.
6467 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6468 glue() in SDCCglue.c creates an area for it.
6470 2002-09-03 Borut Razem <borut.razem AT siol.net>
6471 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6472 sdcc/src/pic/glue.c:
6473 introduced atexit() handler for teporay files removal in case of
6474 errors, assertions, ...
6476 2002-08-29 Borut Razem <borut.razem AT siol.net>
6477 * sdcc/support/cpp2/auto-host_vc_in.h:
6478 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6479 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6480 Maybe there is a similar problem with BORLANDC? It should be checked!
6482 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6483 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6484 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6485 was not executed, and the compiler (cl) launched a warning:
6486 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6488 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6489 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6491 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6492 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6494 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6495 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

6498 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6499 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6500 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6501 - added Release configuration in VS projects
6502 - review of compiler an linker options
6503 - VC .exe files are generated in bin_vc directory, not to interfere
6504 with binaries generated from other projects (cygwin, mingw, bcc ...)
6506 * sdcc/src/yacc.dsp: added
6508 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6509 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6510 and insert the version number definitions from .version
6512 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6514 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6515 added - genarate auto-host.h using auto-host_vc_in.h as template
6518 removed from CVS, generated automatically
6520 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6521 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6523 2002-08-11 Borut Razem <borut.razem AT siol.net>
6524 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6526 2002-08-10 Borut Razem <borut.razem AT siol.net>
6527 * src/SDCCmain.c (main):
6528 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6529 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6530 The consequence was that some temporary files were not removed.
6533 unification of code in functions tempfilename() and tempfile():
6534 function tempnam() is defined in Visual Studio 6.0 and .NET
6536 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6538 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6539 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6540 - removed compiler command line option /WX: Treats all warnings as errors
6541 - update a list of source files, included into the project
6543 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6544 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
