31 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
33 Adding support for replacing ljmps with sjmps in jumptables
34 generated for switch statements. For now you need to set the
35 environment variable SDCC_SJMP_JUMPTABLE to enable this.
36 Now 4 algorithms for mcs51 jumptable generation are used:
37 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
38 addresses loaded pc-relative for up to 112 cases and stack-pushing
39 target addresses loaded with offset from dptr for up to 256 cases.

67 to call when a stack overflow occurs,
68 * (malloc.h): added CVS Id tag,
69 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
71 * added libc directory. The current version of LibC contains string
72 functions, ctype functions and macros and some functions of the
73 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
74 be extensively tested in the future. Standard disclaimer here.
75 Library is not automatically build yet. But one can build it by
76 invoking 'make' inside the libc directory.
77 * added ADC library under libio. Preliminary version yet.

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

102 * (isBankInstruction): modified to return 0 for no banking instruction,
103 and 1 for banking instruction,
104 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
105 caused stop processing pCodes after a inline assembly block,
106 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
107 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
108 registers when it shouldn't,
109 * src/pic16/ralloc.c (allocReg): add preliminary support for
110 supporting a limited set of temporary registers,

114 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
115 genDataPointerSet): ensure assignments always copy in MSB to LSB
117 (loadRegFromAop): recognize CLRH optimization,
118 (genFunction): optimize RECEIVE iCodes in reentrant functions
120 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
122 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
123 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
125 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3117 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3119 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3120 loaded with the linker search paths (-L arguments) and the libraries
3121 to be linked with the current source (-l arguments). Changes
3122 currently will affect only the pic16 port.
3123 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3124 include path the port specific paths and port specific libraries,
3125 * gplink command now contains the $3 argument,
3126 * src/pic16/device.h,
3127 * src/pic16/device.c,: structure PIC_device is made public and
3128 renamed to PIC16_device, the same for variable Pics which is renamed

3143 Documenting changes from previous commits.
3144 * configure.in (version 1.56),
3145 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3146 when generating output files to configure the pic16 library,
3147 but now I've commented it out, since gputils aren't installed in the
3148 SF compile farm, so library won't compile
3150 * device/lib/Makefile.in (version 1.56): initially I've added in
3151 target 'all' the prerequestive 'model-pic16' so it compiled the
3152 pic16 library, but now I've commented it out for the same reasons
3154 * added targets 'model-pic16' and 'objects-pic16' to compile the
3156 * added target 'port-specific-objects-pic16' to handle the
3157 generated libraries and copy them into the build/ directory
3158 * added target 'clean-intermediate-pic16' to clean intermediate
3159 files into pic16 directory

3211 via literal number. The symbol is placed in the corresponding
3212 position of the data ram
3213 * (pic16_dump_section): relocatable and absolute uninitialized
3214 data are now emitted in sorted order to reduce section naming,
3215 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3216 weren't marked as being in the access bank,
3218 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3220 Added portion of GNU PIC Library under the directory
3221 device/include/pic16 and device/lib/pic16. These files
3222 contain the declarations of SFRs for the PIC18Fxx2 devices.
3223 The directory is initialized via configure from toplevel.
3225 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3227 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3253 all over. Telling LaTeX to be less strict with word spacing
3254 to better keep the right margin. Changed some notes about
3255 maintainance of the ports in section 3.2.1 - is it OK like this?
3257 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3297 * src/pic16/peeph.def: all peepholes with movff are commented out,
3298 because there is a problem in the pcode peep optimizer,
3299 * src/pic16/ralloc.c: the register allocator can now reuse local

3336 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3339 * src/z80/main.c: added missed needLinkerScript flags (more than
3340 one port structure defined in these file)
3341 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3376 2004-01-07 Borut Razem <borut.razem AT siol.net>
3378 * support/scripts/sdcc.nsi: update PATH
3379 * support/scripts/sdcc.ico: craeted

3392 include information about variables allocated to the overlay
3395 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3397 * as/mcs51/lkmain.c: Help about -Y option

3407 LEFT_OP (left shift)
3409 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3411 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3412 (default behaviour).
3414 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3416 A python script to validate compiler diagnostic messages. It can be
3417 used to verify that sdcc complains about bad c source code and
3418 gives a good location of the error.
3419 * support/valdiag/Makefile,
3420 * support/valdiag/valdiag.py,
3421 * support/valdiag/tests/*
3423 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3425 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3436 * src/common.h: added ifndef/define/endif macros
3437 around the header file.
3438 Bug reported from Jesus Calvino-Fraga
3440 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3442 * sdcc.spec: updated
3443 * device/include/Makefile.in: don't install CVS directories
3444 * device/lib/Makefile.in: added removal of CVS directories after install
3445 * doc/Makefile: fixed install, added local_icons
3446 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3447 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3448 * src/ds390/gen.c (genRightShift): fixed bug #870788
3449 * src/SDCCast.c (decorateType): fixed bug #870781
3451 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3453 PIC16 port related changes:
3454 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3455 added variable stackPos,
3457 * gen.c: genCall, assignResultValue: added support for
3458 pushing/retrieving function parameters to/from stack,
3459 genFunction,genEndFunction: setup stack frame for the
3461 genAddrOf: will be changed according to bug 863624
3463 * added files genutils.c and genutils.h which contain gen*
3464 debugged and optimised functions extracted from gen.c
3466 * glue.c: added variable 'externs' which holds extern symbols,
3467 pic16emitRegularMap: is modified to properly handle relocatable
3468 symbols under the new scheme,
3469 pic16createInterruptVect: is modified
3470 pic16printPublics: is modified to emit 'global' assembler directives,
3471 added pic16_printExterns to print extern symbols,
3472 pic16glue: initializes stack/frame pointer in the beginning of
3473 the assembly output. Temporary hack, will be corrected later,
3474 because gplink yet does not support stack and SDCC does not
3475 yet support a type of crt0.o object to create the final binary.
3477 * Removed many lines that contain 8051 legacy code.
3478 * The code is finally placed under a 'code' directive.
3479 * Added port specific options.
3481 * _process_pragma: simplified since now we do not need *special*
3482 include file to define SFR registers. But a separate header
3483 will be needed. This will be developed later.
3484 * _pic16_parseOptions: added, parses port specific options:
3485 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3486 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3487 --preplace-udata-with=
3489 * _pic16_setDefaultOptions: modified to initialize section names,
3490 but hack is temporarly out of order since it needs improvement.
3491 * _pic16_genAssemblerPreamble: configuration words are emitted by
3492 their address instead of their name. This part is incomplete and
3493 supports only the 18Fxx2 devices. Other devices will emit an error
3494 during assembly since they do not contain the same set of config
3496 * _pic16_genIVT: is modified,
3498 * pcode.c: added definitions for some hardware registers that are needed
3500 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3501 All PCI entries are updated. Now LFSR is supported.
3502 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3503 * added pic16_newpCodeOpLit2 to support instructions with
3504 two literal arguments
3505 * pic16_pCode2str: corrected code that emits assembler instructions
3506 with two literal operands and those that have an access bit modifier
3507 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3508 this fixes a bug which caused some labels to be lost, when an
3509 assembler directive was added, i.e. banksel,
3510 * pic16_FixRegisterBanking: improved logic that causes the insertion
3512 * InlineFunction: functions that are called once, are not any more
3513 inlined. This can be a port option in the future,
3515 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3517 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3518 hold the corresponding uninitialized symbols,
3519 * pic16_allocProcessorRegister: registers have explicit marked the
3521 * pic16_allocInternalRegister: registers are explicit marked as
3523 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3524 processing list, so bit registers were lost,
3527 * ralloc.h: added field 'accessBank' and original symbol operand
3528 in register definition,
3529 * removed the field isMapped from register definition,
3531 ** Several functions have been removed from various sources:
3532 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3533 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3534 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3535 pic16_assignRelocatableRegisters
3537 ** others have been introduced:
3538 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3539 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3541 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3543 * support/scripts/inc2h.pl: changed definition of BIT_AT
3544 to emit 'sbit at' instead of 'bit at'. This was a request.
3546 PIC16 port related preliminary changes:
3547 * gen.c: prefixed function popRegFromString with
3548 pic16_ and all references to it corrected
3549 * pcode.c: all pic16_pc_* hardware registers prefixed
3550 with underscore (_),
3551 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3552 * ralloc.c: newReg(): when register is REG_SFR then
3553 set address to rIdx,
3554 pic16_allocProcessorRegister(): marks register wasUsed=0
3555 pic16_writeUsedRegs(): added a call to assign processor
3556 registers via pic16_assignFixedRegisters
3558 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3560 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3561 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3562 variables in unused register banks. Also the SSEG is placed
3563 wherever there is enough space for it, and IDATA can be anywhere
3564 in internal RAM. For now compile using -Wl-Y[stack_size].
3565 The mem file is different for this option as well, since it
3566 makes no sense of talking about DSEG lenght.
3568 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3570 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3571 in certain cases, e.g. when ROM assignment, patch provided
3572 from Albert den Haan.
3574 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4597 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4598 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4617 A few small changes that speed up the peephole optimizer.
4621 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4623 Try to make the peephole optimizer smarter by maintaining
4624 an association between the assembly source code and the
4625 iCodes that originated them. Put this information to use
4626 with a new peephole rule condition "notVolatile" so that
4627 the rules can be aggressive yet still safe.
4632 * src/mcs51/peeph.def
4634 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4638 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

4640 if the left or right operand symbols have the accuse flag set.
4642 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4644 Changed the type of the result of the ! (NOT) operator to char;
4645 previously it returned the same type as the source. This allows
4646 us to eliminate all the genFloatNot functions (all of its target
4647 implementations were very buggy) since !float can use the same
4650 * src/SDCCicode.c (ast2iCode): ! returns char

4652 * src/ds390/gen.c (genNot, genNotFloat),
4653 * src/z80/gen.c (genNot, genNotFloat),
4654 * src/pic/gen.c (genNot, genNotFloat),

4659 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4660 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4661 during interrupts. Ensure WSAVE is located at a shared bank address.
4662 2. Fixed page selection in some places
4663 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4664 the registers name strings.
4665 4. Fixed "signed / unsigned compare" compiler warnings.
4666 5. The PIC port manages its own allocation of the general purpose
4667 registers, but makes no attempt to reuse them. As a result when
4668 compiling it soon runs out of general purpose registers. Some
4669 additional code was added to the files pcode.c and device.c to walk
4670 through the function call tree and rename the registers so that they
4680 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4687 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4689 Made bitfield a distinct type from bit so that bitfields
4690 convert as per ANSI C and bits retain their traditional
4691 boolean style behaviour. Implemented bitfield support in
4699 * src/ds390/gen.c: bit v bitfield split
4700 * src/z80/gen.c: New support for bitfields

4704 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4706 Rules 246.x, 247.x relate to bitfields, the others speed up
4707 access to xdata mapped I/O devices.
4709 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4711 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4713 Cleaned up genPackBits and genUnpackBits and added two helper
4714 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4715 for literal assignments in genPackBits (thanks to Frieder for
4721 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4723 Fixed bug #748310 (pointer to function type mishandled when the
4724 function name is omitted). Also fixed a SIGSEGV when a function
4725 attribute (reentrant, etc) is used on a non-function or on a
4726 function but misplaced before the parameter list.

4753 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4755 Made the constant following the "interrupt" keyword optional. If
4756 omitted, the function will not automatically be given an entry
4757 in the interrupt vector table (similar to #pragma NOIV, but
4758 less syntacticly kludgy). The interrupt number is also now
4759 range checked. Also fixed a bug in the high order bit example

5262 * src/pic16/pcode.c: Cleaned warnings
5263 * src/pic16/pcodeflow.c: Cleaned warnings
5264 * src/pic16/pcoderegs.c: Cleaned warnings

5280 it can be defined with CFLAGS when running configure
5281 * src/SDCCmain.c: fixed compiling + linking with object files
5283 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5285 * configure.in: configure for pic16 port,
5286 added --disable-pic16-port
5287 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5288 * src/SDCCmain.c: linkOptions is changed to set *,
5289 added if/endif conditional macros to remove options help
5290 messages from optionsTable when a port is not configured, added
5291 support for the PIc16 port in the ports table, when executing
5292 the compiler with no port specified on command line, a default
5293 port is selected with the new macro DEFAULT_PORT which is
5294 defined in port.h, in setDefaultOptions() linkOptions is removed
5295 from initialization assignment, since now it is a set,
5296 parseCmdLine uses setParseWithComma for linkOptions, in
5297 linkEdit() linkOptions are accessed with new function indexSet()
5298 which returns the i'th item of a set variable. See SDCCset.c, in
5299 linkEdit() when calling buildCmdLine(), added linkOptions as
5300 last argument. Now users can pass arguments to gplink via the
5301 -Wl option, main() uses pic16glue() to glue up pic16 programs

5313 * src/pic16/glue.c: commented out some error producing lines
5314 * src/pic16/main.c: __config directives are commented out to stop
5315 gpasm complaining and test the linkage with gplink, _linkCmd and
5316 _asmCmd changed to be more gplink and gpasm friendly
5317 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5318 produced an error when parsed, peep rule 12 is added to utilize
5319 movff, but it is commented out since the pCode does not support
5320 yet a command with 2 address arguments
5322 2003-05-18 <johan AT balder>
5324 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5351 2003-05-11 Borut Razem <borut.razem AT siol.net>
5353 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5354 the path of bin directory, so that PATH is the only env. variable, which has to be set

6359 * src/SDCCicode.c: fixed array add
6361 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6362 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6363 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6365 2003-01-04 <johan AT balder>
6367 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6369 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6370 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6372 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6373 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6382 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6383 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6385 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6387 * in \sdcc\as\mcs51\ changed these files in order to create an
6388 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6389 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6390 following files to include the previous two files: aslink.dsp,
6391 Makefile.aslink, Makefile.bcc, and Makefile.in.
6393 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6394 .adb instead of .cdb
6396 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6398 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6399 value from option --iram-size.
6401 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6403 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6406 2002-09-18 <wiml AT hhhh.org>
6408 * SDCClrange.h: exposed setFromRange() and setToRange()
6409 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6410 packRegsForAccUse() (bug 542397)
6411 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6412 multiple times and emitting the fetch operations more than once
6413 added aopGetUsesAcc() function to allow binary operators to
6414 fetch their operands in the correct order; made genMinus() emit
6415 compact code for X = LITERAL - Y
6417 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6418 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6419 sprintf() in line 1267.
6421 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6422 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6425 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6426 Changes to aslink (All the changes are marked with 'JCF'):
6428 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6431 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6432 area BSEG. Also moves, if possible, the DATA area down into the internal
6433 ram so more space is available.
6435 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6438 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6439 not bytes. Function summary() which creates a memory usage summary
6440 file with extension .mem. Reports of overlaping stack and small stack
6441 size. If the space for the stack is less than 16 bytes aslink trows a
6444 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6445 the 8051. Option 'y' for memory summary output file.
6447 Changes to sdcc (All the changes are marked with 'JCF'):
6449 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6451 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6452 overlaying area for it (uses RegBankUsed[4]).
6454 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6455 bank zero as used by default. By default aslink locates the stack
6456 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6457 the creation of the .mem file. Delegates the allocation of data area
6458 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6459 the begining of the stack area to aslink.
6461 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6462 glue() in SDCCglue.c creates an area for it.
6464 2002-09-03 Borut Razem <borut.razem AT siol.net>
6465 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6466 sdcc/src/pic/glue.c:
6467 introduced atexit() handler for teporay files removal in case of
6468 errors, assertions, ...
6470 2002-08-29 Borut Razem <borut.razem AT siol.net>
6471 * sdcc/support/cpp2/auto-host_vc_in.h:
6472 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6473 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6474 Maybe there is a similar problem with BORLANDC? It should be checked!
6476 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6477 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6478 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6479 was not executed, and the compiler (cl) launched a warning:
6480 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6482 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6483 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6485 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6486 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6488 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6489 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6490 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6491 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6492 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6493 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6494 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6495 - added Release configuration in VS projects
6496 - review of compiler an linker options
6497 - VC .exe files are generated in bin_vc directory, not to interfere
6498 with binaries generated from other projects (cygwin, mingw, bcc ...)
6500 * sdcc/src/yacc.dsp: added
6502 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6503 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6504 and insert the version number definitions from .version
6506 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6508 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6509 added - genarate auto-host.h using auto-host_vc_in.h as template
6512 removed from CVS, generated automatically
6514 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6515 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6517 2002-08-11 Borut Razem <borut.razem AT siol.net>
6518 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6520 2002-08-10 Borut Razem <borut.razem AT siol.net>
6521 * src/SDCCmain.c (main):
6522 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6523 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6524 The consequence was that some temporary files were not removed.
6527 unification of code in functions tempfilename() and tempfile():
6528 function tempnam() is defined in Visual Studio 6.0 and .NET
6530 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6532 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6533 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6534 - removed compiler command line option /WX: Treats all warnings as errors
6535 - update a list of source files, included into the project
6537 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6538 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6539 changed project type to Generic Project so that can be correcly converted to VS.NET project
6541 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6543 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6545 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

6736 Previous fix was not good. basic blocks that have "break" or "return" are
6737 not really partof a loop , but live ranges used in these blocks should
6738 be live thru the entire loop, so set partOfLoop but don't add them to
