3 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
5 (setFromConditionArgs): friendly operand parser for peephole rules,
6 (operandBaseName, operandsNotRelated): new peephole condition
7 "operandsNotRelated" -- similar to "operandsNotSame", but takes
8 architecture specific register naming into account, handles n-way
9 comparisons, and supports quoted literals
10 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
12 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

20 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
22 Adding support for replacing ljmps with sjmps in jumptables
23 generated for switch statements. For now you need to set the
24 environment variable SDCC_SJMP_JUMPTABLE to enable this.
25 Now 4 algorithms for mcs51 jumptable generation are used:
26 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
27 addresses loaded pc-relative for up to 112 cases and stack-pushing
28 target addresses loaded with offset from dptr for up to 256 cases.
30 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
31 * src/mcs51/main.c: adapted constants for switch table generation
32 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

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

76 * (pic16_storeForReturn): optimized return of 0,
77 * (genCmp): experimental code for new genCmp which uses PIC18's
78 special compare&skip instructions. Initial tests fail some times
79 with variables grater than 1 byte in size, so new code is disabled,
80 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
82 * (genCast): began a fix to optimize the casting of a bit to another
83 bit, now assigning a bitfield to another bitfield will fail, sorry,
84 * src/pic16/main.c: disabled the use of lr-support feature,
85 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
86 * added some function prototypes, added function _debugf prototype,
87 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
88 bits with offset (case PO_GPR_BIT),
89 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
91 * (isBankInstruction): modified to return 0 for no banking instruction,
92 and 1 for banking instruction,
93 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
94 caused stop processing pCodes after a inline assembly block,
95 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
96 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
97 registers when it shouldn't,
98 * src/pic16/ralloc.c (allocReg): add preliminary support for
99 supporting a limited set of temporary registers,
101 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

106 (loadRegFromAop): recognize CLRH optimization,
107 (genFunction): optimize RECEIVE iCodes in reentrant functions
109 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
111 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
112 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
114 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3106 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3108 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3109 loaded with the linker search paths (-L arguments) and the libraries
3110 to be linked with the current source (-l arguments). Changes
3111 currently will affect only the pic16 port.
3112 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3113 include path the port specific paths and port specific libraries,
3114 * gplink command now contains the $3 argument,
3115 * src/pic16/device.h,
3116 * src/pic16/device.c,: structure PIC_device is made public and
3117 renamed to PIC16_device, the same for variable Pics which is renamed

3132 Documenting changes from previous commits.
3133 * configure.in (version 1.56),
3134 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3135 when generating output files to configure the pic16 library,
3136 but now I've commented it out, since gputils aren't installed in the
3137 SF compile farm, so library won't compile
3139 * device/lib/Makefile.in (version 1.56): initially I've added in
3140 target 'all' the prerequestive 'model-pic16' so it compiled the
3141 pic16 library, but now I've commented it out for the same reasons
3143 * added targets 'model-pic16' and 'objects-pic16' to compile the
3145 * added target 'port-specific-objects-pic16' to handle the
3146 generated libraries and copy them into the build/ directory
3147 * added target 'clean-intermediate-pic16' to clean intermediate
3148 files into pic16 directory
3149 * in target 'installdirs' added line to create directory pic16 in
3150 the installation path
3152 * device/include/Makefile.in (version 1.11): in target 'install'
3153 added lines to copy all header files to installation path,
3154 * in target 'installdirs' added line create directory for pic16
3155 headers in the installation path

3200 via literal number. The symbol is placed in the corresponding
3201 position of the data ram
3202 * (pic16_dump_section): relocatable and absolute uninitialized
3203 data are now emitted in sorted order to reduce section naming,
3204 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3205 weren't marked as being in the access bank,
3207 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3209 Added portion of GNU PIC Library under the directory
3210 device/include/pic16 and device/lib/pic16. These files
3211 contain the declarations of SFRs for the PIC18Fxx2 devices.

3242 all over. Telling LaTeX to be less strict with word spacing
3243 to better keep the right margin. Changed some notes about
3244 maintainance of the ports in section 3.2.1 - is it OK like this?
3246 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3286 * src/pic16/peeph.def: all peepholes with movff are commented out,
3287 because there is a problem in the pcode peep optimizer,
3288 * src/pic16/ralloc.c: the register allocator can now reuse local

3381 include information about variables allocated to the overlay
3384 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3386 * as/mcs51/lkmain.c: Help about -Y option

3398 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3400 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3401 (default behaviour).
3403 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3405 A python script to validate compiler diagnostic messages. It can be
3406 used to verify that sdcc complains about bad c source code and
3407 gives a good location of the error.
3408 * support/valdiag/Makefile,
3409 * support/valdiag/valdiag.py,
3410 * support/valdiag/tests/*
3412 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3425 * src/common.h: added ifndef/define/endif macros
3426 around the header file.
3427 Bug reported from Jesus Calvino-Fraga
3429 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3431 * sdcc.spec: updated
3432 * device/include/Makefile.in: don't install CVS directories
3433 * device/lib/Makefile.in: added removal of CVS directories after install
3434 * doc/Makefile: fixed install, added local_icons
3435 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3436 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3437 * src/ds390/gen.c (genRightShift): fixed bug #870788
3438 * src/SDCCast.c (decorateType): fixed bug #870781
3440 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3442 PIC16 port related changes:
3443 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3444 added variable stackPos,
3446 * gen.c: genCall, assignResultValue: added support for
3447 pushing/retrieving function parameters to/from stack,
3448 genFunction,genEndFunction: setup stack frame for the
3450 genAddrOf: will be changed according to bug 863624
3452 * added files genutils.c and genutils.h which contain gen*
3453 debugged and optimised functions extracted from gen.c
3455 * glue.c: added variable 'externs' which holds extern symbols,
3456 pic16emitRegularMap: is modified to properly handle relocatable
3457 symbols under the new scheme,
3458 pic16createInterruptVect: is modified
3459 pic16printPublics: is modified to emit 'global' assembler directives,
3460 added pic16_printExterns to print extern symbols,
3461 pic16glue: initializes stack/frame pointer in the beginning of
3462 the assembly output. Temporary hack, will be corrected later,
3463 because gplink yet does not support stack and SDCC does not
3464 yet support a type of crt0.o object to create the final binary.
3466 * Removed many lines that contain 8051 legacy code.
3467 * The code is finally placed under a 'code' directive.
3468 * Added port specific options.
3470 * _process_pragma: simplified since now we do not need *special*
3471 include file to define SFR registers. But a separate header
3472 will be needed. This will be developed later.
3473 * _pic16_parseOptions: added, parses port specific options:
3474 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3475 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3476 --preplace-udata-with=
3478 * _pic16_setDefaultOptions: modified to initialize section names,
3479 but hack is temporarly out of order since it needs improvement.
3480 * _pic16_genAssemblerPreamble: configuration words are emitted by
3481 their address instead of their name. This part is incomplete and
3482 supports only the 18Fxx2 devices. Other devices will emit an error
3483 during assembly since they do not contain the same set of config
3485 * _pic16_genIVT: is modified,
3487 * pcode.c: added definitions for some hardware registers that are needed
3489 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3490 All PCI entries are updated. Now LFSR is supported.
3491 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3492 * added pic16_newpCodeOpLit2 to support instructions with
3493 two literal arguments
3494 * pic16_pCode2str: corrected code that emits assembler instructions
3495 with two literal operands and those that have an access bit modifier
3496 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3497 this fixes a bug which caused some labels to be lost, when an
3498 assembler directive was added, i.e. banksel,
3499 * pic16_FixRegisterBanking: improved logic that causes the insertion
3501 * InlineFunction: functions that are called once, are not any more
3502 inlined. This can be a port option in the future,
3504 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3506 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3507 hold the corresponding uninitialized symbols,
3508 * pic16_allocProcessorRegister: registers have explicit marked the
3510 * pic16_allocInternalRegister: registers are explicit marked as
3512 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3513 processing list, so bit registers were lost,
3516 * ralloc.h: added field 'accessBank' and original symbol operand
3517 in register definition,
3518 * removed the field isMapped from register definition,
3520 ** Several functions have been removed from various sources:
3521 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3522 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3523 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3524 pic16_assignRelocatableRegisters
3526 ** others have been introduced:
3527 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3528 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3530 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3532 * support/scripts/inc2h.pl: changed definition of BIT_AT
3533 to emit 'sbit at' instead of 'bit at'. This was a request.
3535 PIC16 port related preliminary changes:
3536 * gen.c: prefixed function popRegFromString with
3537 pic16_ and all references to it corrected
3538 * pcode.c: all pic16_pc_* hardware registers prefixed
3539 with underscore (_),
3540 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3541 * ralloc.c: newReg(): when register is REG_SFR then
3542 set address to rIdx,
3543 pic16_allocProcessorRegister(): marks register wasUsed=0
3544 pic16_writeUsedRegs(): added a call to assign processor
3545 registers via pic16_assignFixedRegisters
3547 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3549 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3550 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3551 variables in unused register banks. Also the SSEG is placed
3552 wherever there is enough space for it, and IDATA can be anywhere
3553 in internal RAM. For now compile using -Wl-Y[stack_size].
3554 The mem file is different for this option as well, since it
3555 makes no sense of talking about DSEG lenght.
3557 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3559 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3560 in certain cases, e.g. when ROM assignment, patch provided
3561 from Albert den Haan.
3563 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4586 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4587 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

4606 A few small changes that speed up the peephole optimizer.
4610 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4612 Try to make the peephole optimizer smarter by maintaining
4613 an association between the assembly source code and the
4614 iCodes that originated them. Put this information to use
4615 with a new peephole rule condition "notVolatile" so that
4616 the rules can be aggressive yet still safe.
4621 * src/mcs51/peeph.def
4623 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4627 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

4629 if the left or right operand symbols have the accuse flag set.
4631 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4633 Changed the type of the result of the ! (NOT) operator to char;
4634 previously it returned the same type as the source. This allows
4635 us to eliminate all the genFloatNot functions (all of its target
4636 implementations were very buggy) since !float can use the same
4639 * src/SDCCicode.c (ast2iCode): ! returns char

4648 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4649 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4650 during interrupts. Ensure WSAVE is located at a shared bank address.
4651 2. Fixed page selection in some places
4652 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4653 the registers name strings.
4654 4. Fixed "signed / unsigned compare" compiler warnings.
4655 5. The PIC port manages its own allocation of the general purpose
4656 registers, but makes no attempt to reuse them. As a result when
4657 compiling it soon runs out of general purpose registers. Some
4658 additional code was added to the files pcode.c and device.c to walk
4659 through the function call tree and rename the registers so that they
4669 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

4676 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4678 Made bitfield a distinct type from bit so that bitfields
4679 convert as per ANSI C and bits retain their traditional
4680 boolean style behaviour. Implemented bitfield support in
4688 * src/ds390/gen.c: bit v bitfield split
4689 * src/z80/gen.c: New support for bitfields

4693 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4695 Rules 246.x, 247.x relate to bitfields, the others speed up
4696 access to xdata mapped I/O devices.
4698 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4700 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4702 Cleaned up genPackBits and genUnpackBits and added two helper
4703 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4704 for literal assignments in genPackBits (thanks to Frieder for
4710 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4712 Fixed bug #748310 (pointer to function type mishandled when the
4713 function name is omitted). Also fixed a SIGSEGV when a function
4714 attribute (reentrant, etc) is used on a non-function or on a
4715 function but misplaced before the parameter list.

4742 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4744 Made the constant following the "interrupt" keyword optional. If
4745 omitted, the function will not automatically be given an entry
4746 in the interrupt vector table (similar to #pragma NOIV, but
4747 less syntacticly kludgy). The interrupt number is also now
4748 range checked. Also fixed a bug in the high order bit example

5251 * src/pic16/pcode.c: Cleaned warnings
5252 * src/pic16/pcodeflow.c: Cleaned warnings
5253 * src/pic16/pcoderegs.c: Cleaned warnings
5255 2003-05-19 Scott Dattalo <scott AT dattalo.com>

5268 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5269 it can be defined with CFLAGS when running configure
5270 * src/SDCCmain.c: fixed compiling + linking with object files
5272 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5274 * configure.in: configure for pic16 port,
5275 added --disable-pic16-port
5276 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5277 * src/SDCCmain.c: linkOptions is changed to set *,
5278 added if/endif conditional macros to remove options help
5279 messages from optionsTable when a port is not configured, added
5280 support for the PIc16 port in the ports table, when executing
5281 the compiler with no port specified on command line, a default
5282 port is selected with the new macro DEFAULT_PORT which is
5283 defined in port.h, in setDefaultOptions() linkOptions is removed
5284 from initialization assignment, since now it is a set,
5285 parseCmdLine uses setParseWithComma for linkOptions, in
5286 linkEdit() linkOptions are accessed with new function indexSet()
5287 which returns the i'th item of a set variable. See SDCCset.c, in
5288 linkEdit() when calling buildCmdLine(), added linkOptions as
5289 last argument. Now users can pass arguments to gplink via the
5290 -Wl option, main() uses pic16glue() to glue up pic16 programs

5302 * src/pic16/glue.c: commented out some error producing lines
5303 * src/pic16/main.c: __config directives are commented out to stop
5304 gpasm complaining and test the linkage with gplink, _linkCmd and
5305 _asmCmd changed to be more gplink and gpasm friendly
5306 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5307 produced an error when parsed, peep rule 12 is added to utilize
5308 movff, but it is commented out since the pCode does not support
5309 yet a command with 2 address arguments
5311 2003-05-18 <johan AT balder>
5313 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5340 2003-05-11 Borut Razem <borut.razem AT siol.net>
5342 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6331 2003-01-07 <johan AT balder>
6333 * src/SDCCast.c (decorateType): fixed bug #600035

6348 * src/SDCCicode.c: fixed array add
6350 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6351 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6352 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6354 2003-01-04 <johan AT balder>
6356 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6358 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6359 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6361 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6362 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6371 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6372 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6374 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6376 * in \sdcc\as\mcs51\ changed these files in order to create an
6377 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6378 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6379 following files to include the previous two files: aslink.dsp,
6380 Makefile.aslink, Makefile.bcc, and Makefile.in.
6382 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6383 .adb instead of .cdb
6385 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6387 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6388 value from option --iram-size.
6390 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6392 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6395 2002-09-18 <wiml AT hhhh.org>
6397 * SDCClrange.h: exposed setFromRange() and setToRange()
6398 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6399 packRegsForAccUse() (bug 542397)
6400 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6401 multiple times and emitting the fetch operations more than once
6402 added aopGetUsesAcc() function to allow binary operators to
6403 fetch their operands in the correct order; made genMinus() emit
6404 compact code for X = LITERAL - Y
6406 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6407 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6408 sprintf() in line 1267.
6410 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6411 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6414 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6415 Changes to aslink (All the changes are marked with 'JCF'):
6417 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6420 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6421 area BSEG. Also moves, if possible, the DATA area down into the internal
6422 ram so more space is available.
6424 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6427 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6428 not bytes. Function summary() which creates a memory usage summary
6429 file with extension .mem. Reports of overlaping stack and small stack
6430 size. If the space for the stack is less than 16 bytes aslink trows a
6433 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6434 the 8051. Option 'y' for memory summary output file.
6436 Changes to sdcc (All the changes are marked with 'JCF'):
6438 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6440 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6441 overlaying area for it (uses RegBankUsed[4]).
6443 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6444 bank zero as used by default. By default aslink locates the stack
6445 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6446 the creation of the .mem file. Delegates the allocation of data area
6447 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6448 the begining of the stack area to aslink.
6450 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6451 glue() in SDCCglue.c creates an area for it.
6453 2002-09-03 Borut Razem <borut.razem AT siol.net>
6454 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6455 sdcc/src/pic/glue.c:
6456 introduced atexit() handler for teporay files removal in case of
6457 errors, assertions, ...
6459 2002-08-29 Borut Razem <borut.razem AT siol.net>
6460 * sdcc/support/cpp2/auto-host_vc_in.h:
6461 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6462 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6463 Maybe there is a similar problem with BORLANDC? It should be checked!
6465 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6466 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6467 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6468 was not executed, and the compiler (cl) launched a warning:
6469 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6471 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6472 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6474 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6475 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6477 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6478 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6479 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6480 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6481 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6482 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6483 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6484 - added Release configuration in VS projects
6485 - review of compiler an linker options
6486 - VC .exe files are generated in bin_vc directory, not to interfere
6487 with binaries generated from other projects (cygwin, mingw, bcc ...)
6489 * sdcc/src/yacc.dsp: added
6491 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6492 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6493 and insert the version number definitions from .version
6495 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6497 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6498 added - genarate auto-host.h using auto-host_vc_in.h as template
6501 removed from CVS, generated automatically
6503 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6504 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6506 2002-08-11 Borut Razem <borut.razem AT siol.net>
6507 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6509 2002-08-10 Borut Razem <borut.razem AT siol.net>
6510 * src/SDCCmain.c (main):
6511 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6512 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6513 The consequence was that some temporary files were not removed.
6516 unification of code in functions tempfilename() and tempfile():
6517 function tempnam() is defined in Visual Studio 6.0 and .NET
6519 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6521 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6522 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6523 - removed compiler command line option /WX: Treats all warnings as errors
6524 - update a list of source files, included into the project
6526 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6527 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6528 changed project type to Generic Project so that can be correcly converted to VS.NET project
6530 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6532 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6534 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6536 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6537 added return 0 statements after assert() to make compiler happy
6539 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6540 added newline in the def file to keep MSC compiler satisfied
6542 * sdcc/src/z80/gen.c:
6543 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6544 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6545 - solved MSC error in function aopDump()
