11 * src/pic16/pcode.c: applied patches #1068154 and #1070213
13 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
15 Large cummulative patch for pic16 port.
16 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
17 to call when a stack overflow occurs,
18 * (malloc.h): added CVS Id tag,
19 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
21 * added libc directory. The current version of LibC contains string
22 functions, ctype functions and macros and some functions of the
23 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
24 be extensively tested in the future. Standard disclaimer here.
25 Library is not automatically build yet. But one can build it by
26 invoking 'make' inside the libc directory.
27 * added ADC library under libio. Preliminary version yet.
29 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
30 * src/pic16/gen.c (aopForRemat): asmop size is filled by
31 aopForRemat() now and not by pic16_aopOp(),
32 * (pic16_popGetTempReg): removed warning messgae when allocating
33 temporary registers, its a buggy feature and will be removed,
34 * (pic16_popGet): set register instance field in AOP_CRY,
35 * (pic16_outBitC): fixed for results in size greater than 1,
36 * (genUminusFloat): fixed for pic16, ported code from mcs51,
37 * (pic16_storeForReturn): optimized return of 0,
38 * (genCmp): experimental code for new genCmp which uses PIC18's
39 special compare&skip instructions. Initial tests fail some times
40 with variables grater than 1 byte in size, so new code is disabled,
41 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
43 * (genCast): began a fix to optimize the casting of a bit to another
44 bit, now assigning a bitfield to another bitfield will fail, sorry,
45 * src/pic16/main.c: disabled the use of lr-support feature,
46 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
47 * added some function prototypes, added function _debugf prototype,
48 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
49 bits with offset (case PO_GPR_BIT),
50 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
52 * (isBankInstruction): modified to return 0 for no banking instruction,
53 and 1 for banking instruction,
54 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
55 caused stop processing pCodes after a inline assembly block,
56 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
57 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
58 registers when it shouldn't,
59 * src/pic16/ralloc.c (allocReg): add preliminary support for
60 supporting a limited set of temporary registers,
62 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
64 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
65 genDataPointerSet): ensure assignments always copy in MSB to LSB
67 (loadRegFromAop): recognize CLRH optimization,
68 (genFunction): optimize RECEIVE iCodes in reentrant functions
70 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
72 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
73 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
75 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
76 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
79 2004-11-19 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
81 * device/lib/_gptrget.c (_gptrget),
82 * device/lib/_gptrgetc.c (_gptrgetc),
83 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
84 instead of sjmp to ret

2721 promotion behaviour; env. var. SDCC_NEWONEBYTEOPS selects the new,
2722 SDCC_OLDONEBYTEOPS selects the old behaviour

3067 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3069 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3070 loaded with the linker search paths (-L arguments) and the libraries
3071 to be linked with the current source (-l arguments). Changes
3072 currently will affect only the pic16 port.
3073 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3074 include path the port specific paths and port specific libraries,
3075 * gplink command now contains the $3 argument,
3076 * src/pic16/device.h,
3077 * src/pic16/device.c,: structure PIC_device is made public and
3078 renamed to PIC16_device, the same for variable Pics which is renamed

3093 Documenting changes from previous commits.
3094 * configure.in (version 1.56),
3095 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3096 when generating output files to configure the pic16 library,
3097 but now I've commented it out, since gputils aren't installed in the
3098 SF compile farm, so library won't compile
3100 * device/lib/Makefile.in (version 1.56): initially I've added in
3101 target 'all' the prerequestive 'model-pic16' so it compiled the
3102 pic16 library, but now I've commented it out for the same reasons
3104 * added targets 'model-pic16' and 'objects-pic16' to compile the
3106 * added target 'port-specific-objects-pic16' to handle the
3107 generated libraries and copy them into the build/ directory
3108 * added target 'clean-intermediate-pic16' to clean intermediate
3109 files into pic16 directory
3110 * in target 'installdirs' added line to create directory pic16 in
3111 the installation path
3113 * device/include/Makefile.in (version 1.11): in target 'install'
3114 added lines to copy all header files to installation path,
3115 * in target 'installdirs' added line create directory for pic16
3116 headers in the installation path

3132 option so that it actually works. Made it specific to the z80, since
3133 the gbz80 doesn't have these kinds of I/O ports.
3135 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3137 * device/include/z180.h,

3161 via literal number. The symbol is placed in the corresponding
3162 position of the data ram
3163 * (pic16_dump_section): relocatable and absolute uninitialized
3164 data are now emitted in sorted order to reduce section naming,

3166 weren't marked as being in the access bank,
3168 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3170 Added portion of GNU PIC Library under the directory
3171 device/include/pic16 and device/lib/pic16. These files
3172 contain the declarations of SFRs for the PIC18Fxx2 devices.
3173 The directory is initialized via configure from toplevel.
3175 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3203 all over. Telling LaTeX to be less strict with word spacing
3204 to better keep the right margin. Changed some notes about
3205 maintainance of the ports in section 3.2.1 - is it OK like this?
3207 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3245 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3247 * src/pic16/peeph.def: all peepholes with movff are commented out,
3248 because there is a problem in the pcode peep optimizer,
3249 * src/pic16/ralloc.c: the register allocator can now reuse local

3326 2004-01-07 Borut Razem <borut.razem AT siol.net>
3328 * support/scripts/sdcc.nsi: update PATH
3329 * support/scripts/sdcc.ico: craeted

3342 include information about variables allocated to the overlay
3345 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3347 * as/mcs51/lkmain.c: Help about -Y option

3359 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3361 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3362 (default behaviour).
3364 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3366 A python script to validate compiler diagnostic messages. It can be
3367 used to verify that sdcc complains about bad c source code and
3368 gives a good location of the error.
3369 * support/valdiag/Makefile,
3370 * support/valdiag/valdiag.py,
3371 * support/valdiag/tests/*
3373 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3375 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3386 * src/common.h: added ifndef/define/endif macros
3387 around the header file.
3388 Bug reported from Jesus Calvino-Fraga
3390 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3392 * sdcc.spec: updated
3393 * device/include/Makefile.in: don't install CVS directories
3394 * device/lib/Makefile.in: added removal of CVS directories after install
3395 * doc/Makefile: fixed install, added local_icons
3396 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3397 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3398 * src/ds390/gen.c (genRightShift): fixed bug #870788
3399 * src/SDCCast.c (decorateType): fixed bug #870781
3401 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3403 PIC16 port related changes:
3404 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3405 added variable stackPos,
3407 * gen.c: genCall, assignResultValue: added support for
3408 pushing/retrieving function parameters to/from stack,
3409 genFunction,genEndFunction: setup stack frame for the
3411 genAddrOf: will be changed according to bug 863624
3413 * added files genutils.c and genutils.h which contain gen*
3414 debugged and optimised functions extracted from gen.c
3416 * glue.c: added variable 'externs' which holds extern symbols,
3417 pic16emitRegularMap: is modified to properly handle relocatable
3418 symbols under the new scheme,
3419 pic16createInterruptVect: is modified
3420 pic16printPublics: is modified to emit 'global' assembler directives,
3421 added pic16_printExterns to print extern symbols,
3422 pic16glue: initializes stack/frame pointer in the beginning of
3423 the assembly output. Temporary hack, will be corrected later,
3424 because gplink yet does not support stack and SDCC does not
3425 yet support a type of crt0.o object to create the final binary.
3427 * Removed many lines that contain 8051 legacy code.
3428 * The code is finally placed under a 'code' directive.
3429 * Added port specific options.
3431 * _process_pragma: simplified since now we do not need *special*
3432 include file to define SFR registers. But a separate header
3433 will be needed. This will be developed later.
3434 * _pic16_parseOptions: added, parses port specific options:
3435 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3436 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3437 --preplace-udata-with=
3439 * _pic16_setDefaultOptions: modified to initialize section names,
3440 but hack is temporarly out of order since it needs improvement.
3441 * _pic16_genAssemblerPreamble: configuration words are emitted by
3442 their address instead of their name. This part is incomplete and
3443 supports only the 18Fxx2 devices. Other devices will emit an error
3444 during assembly since they do not contain the same set of config
3446 * _pic16_genIVT: is modified,
3448 * pcode.c: added definitions for some hardware registers that are needed
3450 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3451 All PCI entries are updated. Now LFSR is supported.
3452 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3453 * added pic16_newpCodeOpLit2 to support instructions with
3454 two literal arguments
3455 * pic16_pCode2str: corrected code that emits assembler instructions
3456 with two literal operands and those that have an access bit modifier
3457 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3458 this fixes a bug which caused some labels to be lost, when an
3459 assembler directive was added, i.e. banksel,
3460 * pic16_FixRegisterBanking: improved logic that causes the insertion
3462 * InlineFunction: functions that are called once, are not any more
3463 inlined. This can be a port option in the future,
3465 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3467 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3468 hold the corresponding uninitialized symbols,
3469 * pic16_allocProcessorRegister: registers have explicit marked the
3471 * pic16_allocInternalRegister: registers are explicit marked as
3473 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3474 processing list, so bit registers were lost,
3477 * ralloc.h: added field 'accessBank' and original symbol operand
3478 in register definition,
3479 * removed the field isMapped from register definition,
3481 ** Several functions have been removed from various sources:
3482 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3483 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3484 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3485 pic16_assignRelocatableRegisters
3487 ** others have been introduced:
3488 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3489 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3491 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3493 * support/scripts/inc2h.pl: changed definition of BIT_AT
3494 to emit 'sbit at' instead of 'bit at'. This was a request.
3496 PIC16 port related preliminary changes:
3497 * gen.c: prefixed function popRegFromString with
3498 pic16_ and all references to it corrected
3499 * pcode.c: all pic16_pc_* hardware registers prefixed
3500 with underscore (_),
3501 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3502 * ralloc.c: newReg(): when register is REG_SFR then
3503 set address to rIdx,
3504 pic16_allocProcessorRegister(): marks register wasUsed=0
3505 pic16_writeUsedRegs(): added a call to assign processor
3506 registers via pic16_assignFixedRegisters
3508 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3510 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3511 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3512 variables in unused register banks. Also the SSEG is placed
3513 wherever there is enough space for it, and IDATA can be anywhere
3514 in internal RAM. For now compile using -Wl-Y[stack_size].
3515 The mem file is different for this option as well, since it
3516 makes no sense of talking about DSEG lenght.
3518 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3520 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3521 in certain cases, e.g. when ROM assignment, patch provided
3522 from Albert den Haan.
3524 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3667 * src/mcs51/peephole.def,
3668 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3669 (allows non-interrupt and interrupt code to safely compete for a resource
3670 without the non-interrupt code having to disable interrupts)
3672 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3674 * src/SDCCicode.c (geniCodeAdd),

3694 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3696 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
3698 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3767 it breaks with bitfields, extern declarations, and gcse analysis.
3768 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3769 could be assigned through a pointer, so don't complain.

4547 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4548 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4549 type for bits was changed. It resulted in bit variables becoming
4550 global, which is not permitted in PIC 14 assembly output.

4567 A few small changes that speed up the peephole optimizer.
4571 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4573 Try to make the peephole optimizer smarter by maintaining
4574 an association between the assembly source code and the
4575 iCodes that originated them. Put this information to use
4576 with a new peephole rule condition "notVolatile" so that
4577 the rules can be aggressive yet still safe.
4582 * src/mcs51/peeph.def
4584 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4588 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4589 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4590 if the left or right operand symbols have the accuse flag set.
4592 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4594 Changed the type of the result of the ! (NOT) operator to char;
4595 previously it returned the same type as the source. This allows
4596 us to eliminate all the genFloatNot functions (all of its target
4597 implementations were very buggy) since !float can use the same
4600 * src/SDCCicode.c (ast2iCode): ! returns char

4609 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4610 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4611 during interrupts. Ensure WSAVE is located at a shared bank address.
4612 2. Fixed page selection in some places
4613 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4614 the registers name strings.
4615 4. Fixed "signed / unsigned compare" compiler warnings.
4616 5. The PIC port manages its own allocation of the general purpose
4617 registers, but makes no attempt to reuse them. As a result when
4618 compiling it soon runs out of general purpose registers. Some
4619 additional code was added to the files pcode.c and device.c to walk
4620 through the function call tree and rename the registers so that they
4630 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4631 genPlus() & genMinus() when the result is the same as left or right

4637 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4639 Made bitfield a distinct type from bit so that bitfields
4640 convert as per ANSI C and bits retain their traditional
4641 boolean style behaviour. Implemented bitfield support in
4649 * src/ds390/gen.c: bit v bitfield split
4650 * src/z80/gen.c: New support for bitfields
4651 * support/regression/tests/bitfields.c: reenabled z80,
4654 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4656 Rules 246.x, 247.x relate to bitfields, the others speed up
4657 access to xdata mapped I/O devices.
4659 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4661 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4663 Cleaned up genPackBits and genUnpackBits and added two helper
4664 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4665 for literal assignments in genPackBits (thanks to Frieder for
4671 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4673 Fixed bug #748310 (pointer to function type mishandled when the
4674 function name is omitted). Also fixed a SIGSEGV when a function
4675 attribute (reentrant, etc) is used on a non-function or on a
4676 function but misplaced before the parameter list.

4706 omitted, the function will not automatically be given an entry
4707 in the interrupt vector table (similar to #pragma NOIV, but

5244 defined in port.h, in setDefaultOptions() linkOptions is removed
5245 from initialization assignment, since now it is a set,
5246 parseCmdLine uses setParseWithComma for linkOptions, in
5247 linkEdit() linkOptions are accessed with new function indexSet()
5248 which returns the i'th item of a set variable. See SDCCset.c, in
5249 linkEdit() when calling buildCmdLine(), added linkOptions as
5250 last argument. Now users can pass arguments to gplink via the
5251 -Wl option, main() uses pic16glue() to glue up pic16 programs

5265 gpasm complaining and test the linkage with gplink, _linkCmd and
5266 _asmCmd changed to be more gplink and gpasm friendly
5267 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5268 produced an error when parsed, peep rule 12 is added to utilize
5269 movff, but it is commented out since the pCode does not support
5270 yet a command with 2 address arguments

6309 * src/SDCCicode.c: fixed array add
6311 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6312 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6313 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6315 2003-01-04 <johan AT balder>
6317 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6319 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6320 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6322 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6323 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6329 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6330 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6332 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6333 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6335 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6337 * in \sdcc\as\mcs51\ changed these files in order to create an
6338 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6339 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6340 following files to include the previous two files: aslink.dsp,
6341 Makefile.aslink, Makefile.bcc, and Makefile.in.
6343 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6344 .adb instead of .cdb
6346 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6348 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6349 value from option --iram-size.
6351 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6353 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6356 2002-09-18 <wiml AT hhhh.org>
6358 * SDCClrange.h: exposed setFromRange() and setToRange()
6359 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6360 packRegsForAccUse() (bug 542397)
6361 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6362 multiple times and emitting the fetch operations more than once
6363 added aopGetUsesAcc() function to allow binary operators to
6364 fetch their operands in the correct order; made genMinus() emit
6365 compact code for X = LITERAL - Y
6367 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6368 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6369 sprintf() in line 1267.
6371 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6372 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6375 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6376 Changes to aslink (All the changes are marked with 'JCF'):
6378 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6381 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6382 area BSEG. Also moves, if possible, the DATA area down into the internal
6383 ram so more space is available.
6385 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6388 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6389 not bytes. Function summary() which creates a memory usage summary
6390 file with extension .mem. Reports of overlaping stack and small stack
6391 size. If the space for the stack is less than 16 bytes aslink trows a
6394 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6395 the 8051. Option 'y' for memory summary output file.
6397 Changes to sdcc (All the changes are marked with 'JCF'):
6399 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6401 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6402 overlaying area for it (uses RegBankUsed[4]).
6404 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6405 bank zero as used by default. By default aslink locates the stack
6406 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6407 the creation of the .mem file. Delegates the allocation of data area
6408 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6409 the begining of the stack area to aslink.
6411 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6412 glue() in SDCCglue.c creates an area for it.
6414 2002-09-03 Borut Razem <borut.razem AT siol.net>
6415 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6416 sdcc/src/pic/glue.c:
6417 introduced atexit() handler for teporay files removal in case of
6418 errors, assertions, ...
6420 2002-08-29 Borut Razem <borut.razem AT siol.net>
6421 * sdcc/support/cpp2/auto-host_vc_in.h:
6422 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6423 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6424 Maybe there is a similar problem with BORLANDC? It should be checked!
6426 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6427 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6428 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6429 was not executed, and the compiler (cl) launched a warning:
6430 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6432 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6433 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6435 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6436 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6438 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6439 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6440 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6441 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6442 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6443 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6444 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6445 - added Release configuration in VS projects
6446 - review of compiler an linker options
6447 - VC .exe files are generated in bin_vc directory, not to interfere
6448 with binaries generated from other projects (cygwin, mingw, bcc ...)
6450 * sdcc/src/yacc.dsp: added
6452 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6453 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6454 and insert the version number definitions from .version
6456 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6458 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6459 added - genarate auto-host.h using auto-host_vc_in.h as template
6462 removed from CVS, generated automatically
6464 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6465 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6467 2002-08-11 Borut Razem <borut.razem AT siol.net>
6468 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6470 2002-08-10 Borut Razem <borut.razem AT siol.net>
6471 * src/SDCCmain.c (main):
6472 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6473 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6474 The consequence was that some temporary files were not removed.
6477 unification of code in functions tempfilename() and tempfile():
6478 function tempnam() is defined in Visual Studio 6.0 and .NET
6480 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6482 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6483 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6484 - removed compiler command line option /WX: Treats all warnings as errors
6485 - update a list of source files, included into the project
6487 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6488 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6489 changed project type to Generic Project so that can be correcly converted to VS.NET project
6491 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6493 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6495 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6497 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6498 added return 0 statements after assert() to make compiler happy
6500 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6501 added newline in the def file to keep MSC compiler satisfied
6503 * sdcc/src/z80/gen.c:
6504 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6505 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6506 - solved MSC error in function aopDump()
6508 * sdcc_vc.h: define PREFIX as "\\sdcc"
6510 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6511 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6513 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6514 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6515 - Rewrote the register banking algorithm.
6516 - Added pCode live-range analysis to registers (for now, only non-used and
6517 singly-used registers optimized away)
6519 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6521 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
6523 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6524 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6526 2002-04-22 Michael Hope <michaelh AT vroom>
6528 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.

6542 * src/z80/peeph.def: Added transpose redundent load rule.
6544 * src/z80/main.c: Added force callee saves for jaune.
6546 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6548 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6550 2002-03-28 Johan Knol <johan AT balder>
6552 * src/SDCCval.c: fixed bug #532436
6554 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6556 Added "char *Processor" field to the port structure.
6559 Added -p option. Allows port dependent processor to be specified.
6562 Initialized the new field char *Processor field to NULL in all ports
