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

74 by anonymous in RFE #1067986, thanks
76 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

3055 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3057 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3058 loaded with the linker search paths (-L arguments) and the libraries
3059 to be linked with the current source (-l arguments). Changes
3060 currently will affect only the pic16 port.
3061 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3062 include path the port specific paths and port specific libraries,
3063 * gplink command now contains the $3 argument,
3064 * src/pic16/device.h,
3065 * src/pic16/device.c,: structure PIC_device is made public and
3066 renamed to PIC16_device, the same for variable Pics which is renamed

3081 Documenting changes from previous commits.
3082 * configure.in (version 1.56),
3083 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3084 when generating output files to configure the pic16 library,
3085 but now I've commented it out, since gputils aren't installed in the
3086 SF compile farm, so library won't compile
3088 * device/lib/Makefile.in (version 1.56): initially I've added in
3089 target 'all' the prerequestive 'model-pic16' so it compiled the
3090 pic16 library, but now I've commented it out for the same reasons
3092 * added targets 'model-pic16' and 'objects-pic16' to compile the
3094 * added target 'port-specific-objects-pic16' to handle the
3095 generated libraries and copy them into the build/ directory
3096 * added target 'clean-intermediate-pic16' to clean intermediate
3097 files into pic16 directory
3098 * in target 'installdirs' added line to create directory pic16 in
3099 the installation path

3102 added lines to copy all header files to installation path,
3103 * in target 'installdirs' added line create directory for pic16
3104 headers in the installation path

3120 option so that it actually works. Made it specific to the z80, since
3121 the gbz80 doesn't have these kinds of I/O ports.
3123 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3125 * device/include/z180.h,

3149 via literal number. The symbol is placed in the corresponding
3150 position of the data ram
3151 * (pic16_dump_section): relocatable and absolute uninitialized
3152 data are now emitted in sorted order to reduce section naming,
3153 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3154 weren't marked as being in the access bank,

3158 Added portion of GNU PIC Library under the directory
3159 device/include/pic16 and device/lib/pic16. These files
3160 contain the declarations of SFRs for the PIC18Fxx2 devices.
3161 The directory is initialized via configure from toplevel.

3235 * src/pic16/peeph.def: all peepholes with movff are commented out,
3236 because there is a problem in the pcode peep optimizer,
3237 * src/pic16/ralloc.c: the register allocator can now reuse local

3347 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3349 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3350 (default behaviour).
3352 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3354 A python script to validate compiler diagnostic messages. It can be
3355 used to verify that sdcc complains about bad c source code and
3356 gives a good location of the error.
3357 * support/valdiag/Makefile,
3358 * support/valdiag/valdiag.py,
3359 * support/valdiag/tests/*

3376 Bug reported from Jesus Calvino-Fraga
3378 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3380 * sdcc.spec: updated
3381 * device/include/Makefile.in: don't install CVS directories
3382 * device/lib/Makefile.in: added removal of CVS directories after install
3383 * doc/Makefile: fixed install, added local_icons
3384 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3385 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3386 * src/ds390/gen.c (genRightShift): fixed bug #870788
3387 * src/SDCCast.c (decorateType): fixed bug #870781
3389 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3391 PIC16 port related changes:
3392 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3393 added variable stackPos,
3395 * gen.c: genCall, assignResultValue: added support for
3396 pushing/retrieving function parameters to/from stack,
3397 genFunction,genEndFunction: setup stack frame for the
3399 genAddrOf: will be changed according to bug 863624
3401 * added files genutils.c and genutils.h which contain gen*
3402 debugged and optimised functions extracted from gen.c
3404 * glue.c: added variable 'externs' which holds extern symbols,
3405 pic16emitRegularMap: is modified to properly handle relocatable
3406 symbols under the new scheme,
3407 pic16createInterruptVect: is modified
3408 pic16printPublics: is modified to emit 'global' assembler directives,
3409 added pic16_printExterns to print extern symbols,
3410 pic16glue: initializes stack/frame pointer in the beginning of
3411 the assembly output. Temporary hack, will be corrected later,
3412 because gplink yet does not support stack and SDCC does not
3413 yet support a type of crt0.o object to create the final binary.
3415 * Removed many lines that contain 8051 legacy code.
3416 * The code is finally placed under a 'code' directive.
3417 * Added port specific options.
3419 * _process_pragma: simplified since now we do not need *special*
3420 include file to define SFR registers. But a separate header
3421 will be needed. This will be developed later.
3422 * _pic16_parseOptions: added, parses port specific options:
3423 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3424 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3425 --preplace-udata-with=
3427 * _pic16_setDefaultOptions: modified to initialize section names,
3428 but hack is temporarly out of order since it needs improvement.
3429 * _pic16_genAssemblerPreamble: configuration words are emitted by
3430 their address instead of their name. This part is incomplete and
3431 supports only the 18Fxx2 devices. Other devices will emit an error
3432 during assembly since they do not contain the same set of config
3434 * _pic16_genIVT: is modified,
3436 * pcode.c: added definitions for some hardware registers that are needed
3438 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3439 All PCI entries are updated. Now LFSR is supported.
3440 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3441 * added pic16_newpCodeOpLit2 to support instructions with
3442 two literal arguments
3443 * pic16_pCode2str: corrected code that emits assembler instructions
3444 with two literal operands and those that have an access bit modifier
3445 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3446 this fixes a bug which caused some labels to be lost, when an
3447 assembler directive was added, i.e. banksel,
3448 * pic16_FixRegisterBanking: improved logic that causes the insertion
3450 * InlineFunction: functions that are called once, are not any more
3451 inlined. This can be a port option in the future,
3453 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3455 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3456 hold the corresponding uninitialized symbols,
3457 * pic16_allocProcessorRegister: registers have explicit marked the
3459 * pic16_allocInternalRegister: registers are explicit marked as
3461 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3462 processing list, so bit registers were lost,
3465 * ralloc.h: added field 'accessBank' and original symbol operand
3466 in register definition,
3467 * removed the field isMapped from register definition,
3469 ** Several functions have been removed from various sources:
3470 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3471 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3472 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3473 pic16_assignRelocatableRegisters
3475 ** others have been introduced:
3476 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3477 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3479 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3481 * support/scripts/inc2h.pl: changed definition of BIT_AT
3482 to emit 'sbit at' instead of 'bit at'. This was a request.
3484 PIC16 port related preliminary changes:
3485 * gen.c: prefixed function popRegFromString with
3486 pic16_ and all references to it corrected
3487 * pcode.c: all pic16_pc_* hardware registers prefixed
3488 with underscore (_),
3489 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3490 * ralloc.c: newReg(): when register is REG_SFR then
3491 set address to rIdx,
3492 pic16_allocProcessorRegister(): marks register wasUsed=0
3493 pic16_writeUsedRegs(): added a call to assign processor
3494 registers via pic16_assignFixedRegisters
3496 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3498 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3499 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3500 variables in unused register banks. Also the SSEG is placed
3501 wherever there is enough space for it, and IDATA can be anywhere
3502 in internal RAM. For now compile using -Wl-Y[stack_size].
3503 The mem file is different for this option as well, since it
3504 makes no sense of talking about DSEG lenght.
3506 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3508 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3509 in certain cases, e.g. when ROM assignment, patch provided
3510 from Albert den Haan.
3512 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3656 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
3657 (allows non-interrupt and interrupt code to safely compete for a resource
3658 without the non-interrupt code having to disable interrupts)
3660 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3662 * src/SDCCicode.c (geniCodeAdd),

3755 it breaks with bitfields, extern declarations, and gcse analysis.
3756 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3757 could be assigned through a pointer, so don't complain.

4535 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4536 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4537 type for bits was changed. It resulted in bit variables becoming

4555 A few small changes that speed up the peephole optimizer.
4559 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4561 Try to make the peephole optimizer smarter by maintaining
4562 an association between the assembly source code and the
4563 iCodes that originated them. Put this information to use
4564 with a new peephole rule condition "notVolatile" so that
4565 the rules can be aggressive yet still safe.
4570 * src/mcs51/peeph.def
4572 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4576 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4577 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4578 if the left or right operand symbols have the accuse flag set.
4580 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4582 Changed the type of the result of the ! (NOT) operator to char;
4583 previously it returned the same type as the source. This allows
4584 us to eliminate all the genFloatNot functions (all of its target
4585 implementations were very buggy) since !float can use the same
4588 * src/SDCCicode.c (ast2iCode): ! returns char

4597 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4598 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4599 during interrupts. Ensure WSAVE is located at a shared bank address.
4600 2. Fixed page selection in some places
4601 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4602 the registers name strings.
4603 4. Fixed "signed / unsigned compare" compiler warnings.
4604 5. The PIC port manages its own allocation of the general purpose
4605 registers, but makes no attempt to reuse them. As a result when
4606 compiling it soon runs out of general purpose registers. Some
4607 additional code was added to the files pcode.c and device.c to walk
4608 through the function call tree and rename the registers so that they
4618 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4619 genPlus() & genMinus() when the result is the same as left or right

4625 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4627 Made bitfield a distinct type from bit so that bitfields
4628 convert as per ANSI C and bits retain their traditional
4629 boolean style behaviour. Implemented bitfield support in
4637 * src/ds390/gen.c: bit v bitfield split
4638 * src/z80/gen.c: New support for bitfields
4639 * support/regression/tests/bitfields.c: reenabled z80,
4642 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4644 Rules 246.x, 247.x relate to bitfields, the others speed up
4645 access to xdata mapped I/O devices.
4647 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4649 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4651 Cleaned up genPackBits and genUnpackBits and added two helper
4652 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4653 for literal assignments in genPackBits (thanks to Frieder for
4659 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4661 Fixed bug #748310 (pointer to function type mishandled when the
4662 function name is omitted). Also fixed a SIGSEGV when a function
4663 attribute (reentrant, etc) is used on a non-function or on a
4664 function but misplaced before the parameter list.
4666 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4668 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

4693 Made the constant following the "interrupt" keyword optional. If
4694 omitted, the function will not automatically be given an entry
4695 in the interrupt vector table (similar to #pragma NOIV, but
4696 less syntacticly kludgy). The interrupt number is also now
4697 range checked. Also fixed a bug in the high order bit example
4704 * support/Util/SDCCerr.c

5229 support for the PIc16 port in the ports table, when executing
5230 the compiler with no port specified on command line, a default
5231 port is selected with the new macro DEFAULT_PORT which is
5232 defined in port.h, in setDefaultOptions() linkOptions is removed
5233 from initialization assignment, since now it is a set,
5234 parseCmdLine uses setParseWithComma for linkOptions, in
5235 linkEdit() linkOptions are accessed with new function indexSet()

6297 * src/SDCCicode.c: fixed array add
6299 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6300 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6301 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6303 2003-01-04 <johan AT balder>
6305 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6307 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6308 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6310 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6311 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6318 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6320 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6321 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6323 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6325 * in \sdcc\as\mcs51\ changed these files in order to create an
6326 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6327 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6328 following files to include the previous two files: aslink.dsp,
6329 Makefile.aslink, Makefile.bcc, and Makefile.in.
6331 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6332 .adb instead of .cdb
6334 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6336 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6337 value from option --iram-size.
6339 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6341 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6344 2002-09-18 <wiml AT hhhh.org>
6346 * SDCClrange.h: exposed setFromRange() and setToRange()
6347 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6348 packRegsForAccUse() (bug 542397)
6349 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6350 multiple times and emitting the fetch operations more than once
6351 added aopGetUsesAcc() function to allow binary operators to
6352 fetch their operands in the correct order; made genMinus() emit
6353 compact code for X = LITERAL - Y
6355 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6356 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6357 sprintf() in line 1267.
6359 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6360 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6363 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6364 Changes to aslink (All the changes are marked with 'JCF'):
6366 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6369 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6370 area BSEG. Also moves, if possible, the DATA area down into the internal
6371 ram so more space is available.
6373 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6376 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6377 not bytes. Function summary() which creates a memory usage summary
6378 file with extension .mem. Reports of overlaping stack and small stack
6379 size. If the space for the stack is less than 16 bytes aslink trows a
6382 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6383 the 8051. Option 'y' for memory summary output file.
6385 Changes to sdcc (All the changes are marked with 'JCF'):
6387 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6389 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6390 overlaying area for it (uses RegBankUsed[4]).
6392 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6393 bank zero as used by default. By default aslink locates the stack
6394 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6395 the creation of the .mem file. Delegates the allocation of data area
6396 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6397 the begining of the stack area to aslink.
6399 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6400 glue() in SDCCglue.c creates an area for it.
6402 2002-09-03 Borut Razem <borut.razem AT siol.net>
6403 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6404 sdcc/src/pic/glue.c:
6405 introduced atexit() handler for teporay files removal in case of
6406 errors, assertions, ...
6408 2002-08-29 Borut Razem <borut.razem AT siol.net>
6409 * sdcc/support/cpp2/auto-host_vc_in.h:
6410 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6411 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6412 Maybe there is a similar problem with BORLANDC? It should be checked!
6414 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6415 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6416 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6417 was not executed, and the compiler (cl) launched a warning:
6418 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6420 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6421 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6423 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6424 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6426 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6427 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6428 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6429 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6430 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6431 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6432 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6433 - added Release configuration in VS projects
6434 - review of compiler an linker options
6435 - VC .exe files are generated in bin_vc directory, not to interfere
6436 with binaries generated from other projects (cygwin, mingw, bcc ...)
6438 * sdcc/src/yacc.dsp: added
6440 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6441 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6442 and insert the version number definitions from .version
6444 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6446 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6447 added - genarate auto-host.h using auto-host_vc_in.h as template
6450 removed from CVS, generated automatically
6452 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6453 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6455 2002-08-11 Borut Razem <borut.razem AT siol.net>
6456 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6458 2002-08-10 Borut Razem <borut.razem AT siol.net>
6459 * src/SDCCmain.c (main):
6460 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6461 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6462 The consequence was that some temporary files were not removed.
6465 unification of code in functions tempfilename() and tempfile():
6466 function tempnam() is defined in Visual Studio 6.0 and .NET
6468 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6470 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6471 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6472 - removed compiler command line option /WX: Treats all warnings as errors
6473 - update a list of source files, included into the project
6475 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6476 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6477 changed project type to Generic Project so that can be correcly converted to VS.NET project
6479 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6481 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6483 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6485 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6486 added return 0 statements after assert() to make compiler happy
6488 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6489 added newline in the def file to keep MSC compiler satisfied
6491 * sdcc/src/z80/gen.c:
6492 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6493 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6494 - solved MSC error in function aopDump()
6496 * sdcc_vc.h: define PREFIX as "\\sdcc"
6498 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6499 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6501 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6502 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6503 - Rewrote the register banking algorithm.
6504 - Added pCode live-range analysis to registers (for now, only non-used and
6505 singly-used registers optimized away)
6507 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6509 * 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.
6511 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6512 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6514 2002-04-22 Michael Hope <michaelh AT vroom>

6530 * src/z80/peeph.def: Added transpose redundent load rule.
6532 * src/z80/main.c: Added force callee saves for jaune.
6534 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6536 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6538 2002-03-28 Johan Knol <johan AT balder>
6540 * src/SDCCval.c: fixed bug #532436
6542 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6544 Added "char *Processor" field to the port structure.
6547 Added -p option. Allows port dependent processor to be specified.
6550 Initialized the new field char *Processor field to NULL in all ports
6553 Compiler generated registers for interrupt context saving
6554 were not getting allocated.
6556 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6559 Fixed left shift. Will promote the left side of a left shift
6560 if a) left shifting more than size of operand or b) when assigned
