9 (setFromConditionArgs): friendly operand parser for peephole rules,
10 (operandBaseName, operandsNotRelated): new peephole condition
11 "operandsNotRelated" -- similar to "operandsNotSame", but takes
12 architecture specific register naming into account, handles n-way
13 comparisons, and supports quoted literals

24 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
26 Adding support for replacing ljmps with sjmps in jumptables
27 generated for switch statements. For now you need to set the
28 environment variable SDCC_SJMP_JUMPTABLE to enable this.
29 Now 4 algorithms for mcs51 jumptable generation are used:
30 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
31 addresses loaded pc-relative for up to 112 cases and stack-pushing
32 target addresses loaded with offset from dptr for up to 256 cases.
34 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
35 * src/mcs51/main.c: adapted constants for switch table generation
36 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

58 Large cummulative patch for pic16 port.
59 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
60 to call when a stack overflow occurs,
61 * (malloc.h): added CVS Id tag,
62 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
64 * added libc directory. The current version of LibC contains string
65 functions, ctype functions and macros and some functions of the
66 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
67 be extensively tested in the future. Standard disclaimer here.
68 Library is not automatically build yet. But one can build it by
69 invoking 'make' inside the libc directory.
70 * added ADC library under libio. Preliminary version yet.
72 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

80 * (pic16_storeForReturn): optimized return of 0,
81 * (genCmp): experimental code for new genCmp which uses PIC18's
82 special compare&skip instructions. Initial tests fail some times
83 with variables grater than 1 byte in size, so new code is disabled,
84 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
86 * (genCast): began a fix to optimize the casting of a bit to another
87 bit, now assigning a bitfield to another bitfield will fail, sorry,
88 * src/pic16/main.c: disabled the use of lr-support feature,
89 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
90 * added some function prototypes, added function _debugf prototype,
91 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
92 bits with offset (case PO_GPR_BIT),
93 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
95 * (isBankInstruction): modified to return 0 for no banking instruction,
96 and 1 for banking instruction,
97 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
98 caused stop processing pCodes after a inline assembly block,
99 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
100 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
101 registers when it shouldn't,
102 * src/pic16/ralloc.c (allocReg): add preliminary support for
103 supporting a limited set of temporary registers,
105 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
107 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
108 genDataPointerSet): ensure assignments always copy in MSB to LSB
110 (loadRegFromAop): recognize CLRH optimization,
111 (genFunction): optimize RECEIVE iCodes in reentrant functions
113 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
115 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
116 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
118 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3110 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3112 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3113 loaded with the linker search paths (-L arguments) and the libraries
3114 to be linked with the current source (-l arguments). Changes
3115 currently will affect only the pic16 port.
3116 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3117 include path the port specific paths and port specific libraries,
3118 * gplink command now contains the $3 argument,
3119 * src/pic16/device.h,
3120 * src/pic16/device.c,: structure PIC_device is made public and

3136 Documenting changes from previous commits.
3137 * configure.in (version 1.56),
3138 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3139 when generating output files to configure the pic16 library,
3140 but now I've commented it out, since gputils aren't installed in the
3141 SF compile farm, so library won't compile
3143 * device/lib/Makefile.in (version 1.56): initially I've added in
3144 target 'all' the prerequestive 'model-pic16' so it compiled the
3145 pic16 library, but now I've commented it out for the same reasons
3147 * added targets 'model-pic16' and 'objects-pic16' to compile the
3149 * added target 'port-specific-objects-pic16' to handle the
3150 generated libraries and copy them into the build/ directory
3151 * added target 'clean-intermediate-pic16' to clean intermediate
3152 files into pic16 directory
3153 * in target 'installdirs' added line to create directory pic16 in
3154 the installation path
3156 * device/include/Makefile.in (version 1.11): in target 'install'
3157 added lines to copy all header files to installation path,

3204 via literal number. The symbol is placed in the corresponding
3205 position of the data ram
3206 * (pic16_dump_section): relocatable and absolute uninitialized
3207 data are now emitted in sorted order to reduce section naming,
3208 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3209 weren't marked as being in the access bank,
3211 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3213 Added portion of GNU PIC Library under the directory
3214 device/include/pic16 and device/lib/pic16. These files
3215 contain the declarations of SFRs for the PIC18Fxx2 devices.

3246 all over. Telling LaTeX to be less strict with word spacing
3247 to better keep the right margin. Changed some notes about
3248 maintainance of the ports in section 3.2.1 - is it OK like this?
3250 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3290 * src/pic16/peeph.def: all peepholes with movff are commented out,
3291 because there is a problem in the pcode peep optimizer,
3292 * src/pic16/ralloc.c: the register allocator can now reuse local

3329 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3332 * src/z80/main.c: added missed needLinkerScript flags (more than
3333 one port structure defined in these file)
3334 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3385 include information about variables allocated to the overlay
3388 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3390 * as/mcs51/lkmain.c: Help about -Y option

3400 LEFT_OP (left shift)
3402 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3404 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3405 (default behaviour).
3407 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3409 A python script to validate compiler diagnostic messages. It can be
3410 used to verify that sdcc complains about bad c source code and
3411 gives a good location of the error.
3412 * support/valdiag/Makefile,
3413 * support/valdiag/valdiag.py,
3414 * support/valdiag/tests/*
3416 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3429 * src/common.h: added ifndef/define/endif macros
3430 around the header file.
3431 Bug reported from Jesus Calvino-Fraga
3433 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3435 * sdcc.spec: updated
3436 * device/include/Makefile.in: don't install CVS directories
3437 * device/lib/Makefile.in: added removal of CVS directories after install
3438 * doc/Makefile: fixed install, added local_icons
3439 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3440 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3441 * src/ds390/gen.c (genRightShift): fixed bug #870788
3442 * src/SDCCast.c (decorateType): fixed bug #870781
3444 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3446 PIC16 port related changes:
3447 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3448 added variable stackPos,
3450 * gen.c: genCall, assignResultValue: added support for
3451 pushing/retrieving function parameters to/from stack,
3452 genFunction,genEndFunction: setup stack frame for the
3454 genAddrOf: will be changed according to bug 863624
3456 * added files genutils.c and genutils.h which contain gen*
3457 debugged and optimised functions extracted from gen.c
3459 * glue.c: added variable 'externs' which holds extern symbols,
3460 pic16emitRegularMap: is modified to properly handle relocatable
3461 symbols under the new scheme,
3462 pic16createInterruptVect: is modified
3463 pic16printPublics: is modified to emit 'global' assembler directives,
3464 added pic16_printExterns to print extern symbols,
3465 pic16glue: initializes stack/frame pointer in the beginning of
3466 the assembly output. Temporary hack, will be corrected later,
3467 because gplink yet does not support stack and SDCC does not
3468 yet support a type of crt0.o object to create the final binary.
3470 * Removed many lines that contain 8051 legacy code.
3471 * The code is finally placed under a 'code' directive.
3472 * Added port specific options.
3474 * _process_pragma: simplified since now we do not need *special*
3475 include file to define SFR registers. But a separate header
3476 will be needed. This will be developed later.
3477 * _pic16_parseOptions: added, parses port specific options:
3478 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3479 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3480 --preplace-udata-with=
3482 * _pic16_setDefaultOptions: modified to initialize section names,
3483 but hack is temporarly out of order since it needs improvement.
3484 * _pic16_genAssemblerPreamble: configuration words are emitted by
3485 their address instead of their name. This part is incomplete and
3486 supports only the 18Fxx2 devices. Other devices will emit an error
3487 during assembly since they do not contain the same set of config
3489 * _pic16_genIVT: is modified,
3491 * pcode.c: added definitions for some hardware registers that are needed
3493 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3494 All PCI entries are updated. Now LFSR is supported.
3495 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3496 * added pic16_newpCodeOpLit2 to support instructions with
3497 two literal arguments
3498 * pic16_pCode2str: corrected code that emits assembler instructions
3499 with two literal operands and those that have an access bit modifier
3500 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3501 this fixes a bug which caused some labels to be lost, when an
3502 assembler directive was added, i.e. banksel,
3503 * pic16_FixRegisterBanking: improved logic that causes the insertion
3505 * InlineFunction: functions that are called once, are not any more
3506 inlined. This can be a port option in the future,
3508 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3510 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3511 hold the corresponding uninitialized symbols,
3512 * pic16_allocProcessorRegister: registers have explicit marked the
3514 * pic16_allocInternalRegister: registers are explicit marked as
3516 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3517 processing list, so bit registers were lost,
3520 * ralloc.h: added field 'accessBank' and original symbol operand
3521 in register definition,
3522 * removed the field isMapped from register definition,
3524 ** Several functions have been removed from various sources:
3525 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3526 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3527 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3528 pic16_assignRelocatableRegisters
3530 ** others have been introduced:
3531 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3532 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3534 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3536 * support/scripts/inc2h.pl: changed definition of BIT_AT
3537 to emit 'sbit at' instead of 'bit at'. This was a request.
3539 PIC16 port related preliminary changes:
3540 * gen.c: prefixed function popRegFromString with
3541 pic16_ and all references to it corrected
3542 * pcode.c: all pic16_pc_* hardware registers prefixed
3543 with underscore (_),
3544 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3545 * ralloc.c: newReg(): when register is REG_SFR then
3546 set address to rIdx,
3547 pic16_allocProcessorRegister(): marks register wasUsed=0
3548 pic16_writeUsedRegs(): added a call to assign processor
3549 registers via pic16_assignFixedRegisters
3551 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3553 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3554 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3555 variables in unused register banks. Also the SSEG is placed
3556 wherever there is enough space for it, and IDATA can be anywhere
3557 in internal RAM. For now compile using -Wl-Y[stack_size].
3558 The mem file is different for this option as well, since it
3559 makes no sense of talking about DSEG lenght.
3561 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3563 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3564 in certain cases, e.g. when ROM assignment, patch provided
3565 from Albert den Haan.
3567 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4590 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4591 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4610 A few small changes that speed up the peephole optimizer.
4614 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4616 Try to make the peephole optimizer smarter by maintaining
4617 an association between the assembly source code and the
4618 iCodes that originated them. Put this information to use
4619 with a new peephole rule condition "notVolatile" so that
4620 the rules can be aggressive yet still safe.
4625 * src/mcs51/peeph.def
4627 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4631 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

4635 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4637 Changed the type of the result of the ! (NOT) operator to char;
4638 previously it returned the same type as the source. This allows
4639 us to eliminate all the genFloatNot functions (all of its target
4640 implementations were very buggy) since !float can use the same
4643 * src/SDCCicode.c (ast2iCode): ! returns char

4655 2. Fixed page selection in some places
4656 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4657 the registers name strings.
4658 4. Fixed "signed / unsigned compare" compiler warnings.
4659 5. The PIC port manages its own allocation of the general purpose
4660 registers, but makes no attempt to reuse them. As a result when
4661 compiling it soon runs out of general purpose registers. Some
4662 additional code was added to the files pcode.c and device.c to walk
4663 through the function call tree and rename the registers so that they
4673 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4680 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4682 Made bitfield a distinct type from bit so that bitfields
4683 convert as per ANSI C and bits retain their traditional
4684 boolean style behaviour. Implemented bitfield support in
4692 * src/ds390/gen.c: bit v bitfield split
4693 * src/z80/gen.c: New support for bitfields
4694 * support/regression/tests/bitfields.c: reenabled z80,
4697 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4699 Rules 246.x, 247.x relate to bitfields, the others speed up
4700 access to xdata mapped I/O devices.
4702 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4704 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4706 Cleaned up genPackBits and genUnpackBits and added two helper
4707 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4708 for literal assignments in genPackBits (thanks to Frieder for
4714 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4716 Fixed bug #748310 (pointer to function type mishandled when the
4717 function name is omitted). Also fixed a SIGSEGV when a function
4718 attribute (reentrant, etc) is used on a non-function or on a
4719 function but misplaced before the parameter list.

4746 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4748 Made the constant following the "interrupt" keyword optional. If
4749 omitted, the function will not automatically be given an entry
4750 in the interrupt vector table (similar to #pragma NOIV, but
4751 less syntacticly kludgy). The interrupt number is also now
4752 range checked. Also fixed a bug in the high order bit example

5255 * src/pic16/pcode.c: Cleaned warnings
5256 * src/pic16/pcodeflow.c: Cleaned warnings
5257 * src/pic16/pcoderegs.c: Cleaned warnings

5270 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5272 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5273 it can be defined with CFLAGS when running configure
5274 * src/SDCCmain.c: fixed compiling + linking with object files
5276 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5278 * configure.in: configure for pic16 port,
5279 added --disable-pic16-port
5280 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5281 * src/SDCCmain.c: linkOptions is changed to set *,
5282 added if/endif conditional macros to remove options help
5283 messages from optionsTable when a port is not configured, added
5284 support for the PIc16 port in the ports table, when executing
5285 the compiler with no port specified on command line, a default
5286 port is selected with the new macro DEFAULT_PORT which is
5287 defined in port.h, in setDefaultOptions() linkOptions is removed
5288 from initialization assignment, since now it is a set,
5289 parseCmdLine uses setParseWithComma for linkOptions, in
5290 linkEdit() linkOptions are accessed with new function indexSet()
5291 which returns the i'th item of a set variable. See SDCCset.c, in
5292 linkEdit() when calling buildCmdLine(), added linkOptions as
5293 last argument. Now users can pass arguments to gplink via the
5294 -Wl option, main() uses pic16glue() to glue up pic16 programs

5306 * src/pic16/glue.c: commented out some error producing lines
5307 * src/pic16/main.c: __config directives are commented out to stop
5308 gpasm complaining and test the linkage with gplink, _linkCmd and
5309 _asmCmd changed to be more gplink and gpasm friendly
5310 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5311 produced an error when parsed, peep rule 12 is added to utilize
5312 movff, but it is commented out since the pCode does not support
5313 yet a command with 2 address arguments
5315 2003-05-18 <johan AT balder>
5317 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5344 2003-05-11 Borut Razem <borut.razem AT siol.net>
5346 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5347 the path of bin directory, so that PATH is the only env. variable, which has to be set

6352 * src/SDCCicode.c: fixed array add
6354 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6355 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6356 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6358 2003-01-04 <johan AT balder>
6360 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6362 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6363 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

6375 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6376 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6378 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6380 * in \sdcc\as\mcs51\ changed these files in order to create an
6381 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6382 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6383 following files to include the previous two files: aslink.dsp,
6384 Makefile.aslink, Makefile.bcc, and Makefile.in.
6386 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6387 .adb instead of .cdb
6389 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6391 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6392 value from option --iram-size.
6394 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6396 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6399 2002-09-18 <wiml AT hhhh.org>
6401 * SDCClrange.h: exposed setFromRange() and setToRange()
6402 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6403 packRegsForAccUse() (bug 542397)
6404 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6405 multiple times and emitting the fetch operations more than once
6406 added aopGetUsesAcc() function to allow binary operators to
6407 fetch their operands in the correct order; made genMinus() emit
6408 compact code for X = LITERAL - Y
6410 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6411 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6412 sprintf() in line 1267.
6414 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6415 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6418 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6419 Changes to aslink (All the changes are marked with 'JCF'):
6421 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6424 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6425 area BSEG. Also moves, if possible, the DATA area down into the internal
6426 ram so more space is available.
6428 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6431 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6432 not bytes. Function summary() which creates a memory usage summary
6433 file with extension .mem. Reports of overlaping stack and small stack
6434 size. If the space for the stack is less than 16 bytes aslink trows a
6437 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6438 the 8051. Option 'y' for memory summary output file.
6440 Changes to sdcc (All the changes are marked with 'JCF'):
6442 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6444 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6445 overlaying area for it (uses RegBankUsed[4]).
6447 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6448 bank zero as used by default. By default aslink locates the stack
6449 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6450 the creation of the .mem file. Delegates the allocation of data area
6451 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6452 the begining of the stack area to aslink.
6454 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6455 glue() in SDCCglue.c creates an area for it.
6457 2002-09-03 Borut Razem <borut.razem AT siol.net>
6458 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6459 sdcc/src/pic/glue.c:
6460 introduced atexit() handler for teporay files removal in case of
6461 errors, assertions, ...
6463 2002-08-29 Borut Razem <borut.razem AT siol.net>
6464 * sdcc/support/cpp2/auto-host_vc_in.h:
6465 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6466 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6467 Maybe there is a similar problem with BORLANDC? It should be checked!
6469 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6470 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6471 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6472 was not executed, and the compiler (cl) launched a warning:
6473 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6475 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6476 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6478 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6479 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6481 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6482 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6483 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6484 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6485 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6486 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6487 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6488 - added Release configuration in VS projects
6489 - review of compiler an linker options
6490 - VC .exe files are generated in bin_vc directory, not to interfere
6491 with binaries generated from other projects (cygwin, mingw, bcc ...)
6493 * sdcc/src/yacc.dsp: added
6495 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6496 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6497 and insert the version number definitions from .version
6499 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6501 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6502 added - genarate auto-host.h using auto-host_vc_in.h as template
6505 removed from CVS, generated automatically
6507 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6508 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6510 2002-08-11 Borut Razem <borut.razem AT siol.net>
6511 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6513 2002-08-10 Borut Razem <borut.razem AT siol.net>
6514 * src/SDCCmain.c (main):
6515 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6516 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6517 The consequence was that some temporary files were not removed.
6520 unification of code in functions tempfilename() and tempfile():
6521 function tempnam() is defined in Visual Studio 6.0 and .NET
6523 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6525 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6526 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6527 - removed compiler command line option /WX: Treats all warnings as errors
6528 - update a list of source files, included into the project
6530 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6531 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6532 changed project type to Generic Project so that can be correcly converted to VS.NET project
6534 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6536 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6538 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6540 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6541 added return 0 statements after assert() to make compiler happy
6543 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6544 added newline in the def file to keep MSC compiler satisfied
6546 * sdcc/src/z80/gen.c:
6547 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6548 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
