3 * device/include/pic/pic16f877.h : added an include file for the PIC16F877 device.
5 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7 Adding support for replacing ljmps with sjmps in jumptables
8 generated for switch statements. For now you need to set the
9 environment variable SDCC_SJMP_JUMPTABLE to enable this.
10 Now 4 algorithms for mcs51 jumptable generation are used:
11 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
12 addresses loaded pc-relative for up to 112 cases and stack-pushing
13 target addresses loaded with offset from dptr for up to 256 cases.
15 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
16 * src/mcs51/main.c: adapted constants for switch table generation
17 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

39 Large cummulative patch for pic16 port.
40 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
41 to call when a stack overflow occurs,
42 * (malloc.h): added CVS Id tag,
43 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
45 * added libc directory. The current version of LibC contains string
46 functions, ctype functions and macros and some functions of the
47 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
48 be extensively tested in the future. Standard disclaimer here.
49 Library is not automatically build yet. But one can build it by
50 invoking 'make' inside the libc directory.
51 * added ADC library under libio. Preliminary version yet.
53 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

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

92 (genFunction): optimize RECEIVE iCodes in reentrant functions
94 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3091 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3093 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3094 loaded with the linker search paths (-L arguments) and the libraries
3095 to be linked with the current source (-l arguments). Changes
3096 currently will affect only the pic16 port.
3097 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3098 include path the port specific paths and port specific libraries,
3099 * gplink command now contains the $3 argument,
3100 * src/pic16/device.h,
3101 * src/pic16/device.c,: structure PIC_device is made public and
3102 renamed to PIC16_device, the same for variable Pics which is renamed

3117 Documenting changes from previous commits.
3118 * configure.in (version 1.56),
3119 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3120 when generating output files to configure the pic16 library,
3121 but now I've commented it out, since gputils aren't installed in the
3122 SF compile farm, so library won't compile
3124 * device/lib/Makefile.in (version 1.56): initially I've added in
3125 target 'all' the prerequestive 'model-pic16' so it compiled the
3126 pic16 library, but now I've commented it out for the same reasons
3128 * added targets 'model-pic16' and 'objects-pic16' to compile the
3130 * added target 'port-specific-objects-pic16' to handle the
3131 generated libraries and copy them into the build/ directory
3132 * added target 'clean-intermediate-pic16' to clean intermediate
3133 files into pic16 directory
3134 * in target 'installdirs' added line to create directory pic16 in
3135 the installation path
3137 * device/include/Makefile.in (version 1.11): in target 'install'
3138 added lines to copy all header files to installation path,
3139 * in target 'installdirs' added line create directory for pic16
3140 headers in the installation path

3155 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3156 option so that it actually works. Made it specific to the z80, since
3157 the gbz80 doesn't have these kinds of I/O ports.
3159 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3227 all over. Telling LaTeX to be less strict with word spacing
3228 to better keep the right margin. Changed some notes about
3229 maintainance of the ports in section 3.2.1 - is it OK like this?
3231 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3271 * src/pic16/peeph.def: all peepholes with movff are commented out,
3272 because there is a problem in the pcode peep optimizer,
3273 * src/pic16/ralloc.c: the register allocator can now reuse local

3366 include information about variables allocated to the overlay
3369 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3371 * as/mcs51/lkmain.c: Help about -Y option

3383 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3385 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3386 (default behaviour).
3388 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3390 A python script to validate compiler diagnostic messages. It can be
3391 used to verify that sdcc complains about bad c source code and
3392 gives a good location of the error.
3393 * support/valdiag/Makefile,
3394 * support/valdiag/valdiag.py,
3395 * support/valdiag/tests/*
3397 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3411 around the header file.
3412 Bug reported from Jesus Calvino-Fraga
3414 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3416 * sdcc.spec: updated
3417 * device/include/Makefile.in: don't install CVS directories
3418 * device/lib/Makefile.in: added removal of CVS directories after install
3419 * doc/Makefile: fixed install, added local_icons
3420 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3421 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3422 * src/ds390/gen.c (genRightShift): fixed bug #870788
3423 * src/SDCCast.c (decorateType): fixed bug #870781
3425 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3427 PIC16 port related changes:
3428 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3429 added variable stackPos,
3431 * gen.c: genCall, assignResultValue: added support for
3432 pushing/retrieving function parameters to/from stack,
3433 genFunction,genEndFunction: setup stack frame for the
3435 genAddrOf: will be changed according to bug 863624
3437 * added files genutils.c and genutils.h which contain gen*
3438 debugged and optimised functions extracted from gen.c
3440 * glue.c: added variable 'externs' which holds extern symbols,
3441 pic16emitRegularMap: is modified to properly handle relocatable
3442 symbols under the new scheme,
3443 pic16createInterruptVect: is modified
3444 pic16printPublics: is modified to emit 'global' assembler directives,
3445 added pic16_printExterns to print extern symbols,
3446 pic16glue: initializes stack/frame pointer in the beginning of
3447 the assembly output. Temporary hack, will be corrected later,
3448 because gplink yet does not support stack and SDCC does not
3449 yet support a type of crt0.o object to create the final binary.
3451 * Removed many lines that contain 8051 legacy code.
3452 * The code is finally placed under a 'code' directive.
3453 * Added port specific options.
3455 * _process_pragma: simplified since now we do not need *special*
3456 include file to define SFR registers. But a separate header
3457 will be needed. This will be developed later.
3458 * _pic16_parseOptions: added, parses port specific options:
3459 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3460 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3461 --preplace-udata-with=
3463 * _pic16_setDefaultOptions: modified to initialize section names,
3464 but hack is temporarly out of order since it needs improvement.
3465 * _pic16_genAssemblerPreamble: configuration words are emitted by
3466 their address instead of their name. This part is incomplete and
3467 supports only the 18Fxx2 devices. Other devices will emit an error
3468 during assembly since they do not contain the same set of config
3470 * _pic16_genIVT: is modified,
3472 * pcode.c: added definitions for some hardware registers that are needed
3474 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3475 All PCI entries are updated. Now LFSR is supported.
3476 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3477 * added pic16_newpCodeOpLit2 to support instructions with
3478 two literal arguments
3479 * pic16_pCode2str: corrected code that emits assembler instructions
3480 with two literal operands and those that have an access bit modifier
3481 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3482 this fixes a bug which caused some labels to be lost, when an
3483 assembler directive was added, i.e. banksel,
3484 * pic16_FixRegisterBanking: improved logic that causes the insertion
3486 * InlineFunction: functions that are called once, are not any more
3487 inlined. This can be a port option in the future,
3489 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3491 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3492 hold the corresponding uninitialized symbols,
3493 * pic16_allocProcessorRegister: registers have explicit marked the
3495 * pic16_allocInternalRegister: registers are explicit marked as
3497 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3498 processing list, so bit registers were lost,
3501 * ralloc.h: added field 'accessBank' and original symbol operand
3502 in register definition,
3503 * removed the field isMapped from register definition,
3505 ** Several functions have been removed from various sources:
3506 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3507 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3508 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3509 pic16_assignRelocatableRegisters
3511 ** others have been introduced:
3512 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3513 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3515 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3517 * support/scripts/inc2h.pl: changed definition of BIT_AT
3518 to emit 'sbit at' instead of 'bit at'. This was a request.
3520 PIC16 port related preliminary changes:
3521 * gen.c: prefixed function popRegFromString with
3522 pic16_ and all references to it corrected
3523 * pcode.c: all pic16_pc_* hardware registers prefixed
3524 with underscore (_),
3525 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3526 * ralloc.c: newReg(): when register is REG_SFR then
3527 set address to rIdx,
3528 pic16_allocProcessorRegister(): marks register wasUsed=0
3529 pic16_writeUsedRegs(): added a call to assign processor
3530 registers via pic16_assignFixedRegisters
3532 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3534 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3535 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3536 variables in unused register banks. Also the SSEG is placed
3537 wherever there is enough space for it, and IDATA can be anywhere
3538 in internal RAM. For now compile using -Wl-Y[stack_size].
3539 The mem file is different for this option as well, since it
3540 makes no sense of talking about DSEG lenght.
3542 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3544 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3545 in certain cases, e.g. when ROM assignment, patch provided
3546 from Albert den Haan.
3548 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3718 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3720 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

3791 it breaks with bitfields, extern declarations, and gcse analysis.
3792 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3793 could be assigned through a pointer, so don't complain.

4571 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4572 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4573 type for bits was changed. It resulted in bit variables becoming

4591 A few small changes that speed up the peephole optimizer.
4595 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4597 Try to make the peephole optimizer smarter by maintaining
4598 an association between the assembly source code and the
4599 iCodes that originated them. Put this information to use
4600 with a new peephole rule condition "notVolatile" so that
4601 the rules can be aggressive yet still safe.
4606 * src/mcs51/peeph.def
4608 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4612 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4613 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4614 if the left or right operand symbols have the accuse flag set.
4616 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4618 Changed the type of the result of the ! (NOT) operator to char;
4619 previously it returned the same type as the source. This allows
4620 us to eliminate all the genFloatNot functions (all of its target
4621 implementations were very buggy) since !float can use the same

4633 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4634 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4635 during interrupts. Ensure WSAVE is located at a shared bank address.
4636 2. Fixed page selection in some places
4637 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4638 the registers name strings.
4639 4. Fixed "signed / unsigned compare" compiler warnings.
4640 5. The PIC port manages its own allocation of the general purpose
4641 registers, but makes no attempt to reuse them. As a result when
4642 compiling it soon runs out of general purpose registers. Some
4643 additional code was added to the files pcode.c and device.c to walk
4644 through the function call tree and rename the registers so that they
4654 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4655 genPlus() & genMinus() when the result is the same as left or right

4661 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4663 Made bitfield a distinct type from bit so that bitfields
4664 convert as per ANSI C and bits retain their traditional
4665 boolean style behaviour. Implemented bitfield support in

4681 access to xdata mapped I/O devices.
4683 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4685 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4687 Cleaned up genPackBits and genUnpackBits and added two helper
4688 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4689 for literal assignments in genPackBits (thanks to Frieder for
4695 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4697 Fixed bug #748310 (pointer to function type mishandled when the
4698 function name is omitted). Also fixed a SIGSEGV when a function
4699 attribute (reentrant, etc) is used on a non-function or on a
4700 function but misplaced before the parameter list.

4729 Made the constant following the "interrupt" keyword optional. If
4730 omitted, the function will not automatically be given an entry
4731 in the interrupt vector table (similar to #pragma NOIV, but
4732 less syntacticly kludgy). The interrupt number is also now
4733 range checked. Also fixed a bug in the high order bit example

4754 unsigned, but are signed by default
4755 * src/SDCCval.c (constVal): rearranged
4756 * src/SDCCval.c (valMod): preliminary fix
4757 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5248 * doc/sdccman.lyx: fixed bug 739745
5249 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
5251 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5253 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5254 it can be defined with CFLAGS when running configure
5255 * src/SDCCmain.c: fixed compiling + linking with object files
5257 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
5259 * configure.in: configure for pic16 port,
5260 added --disable-pic16-port
5261 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5262 * src/SDCCmain.c: linkOptions is changed to set *,
5263 added if/endif conditional macros to remove options help
5264 messages from optionsTable when a port is not configured, added
5265 support for the PIc16 port in the ports table, when executing
5266 the compiler with no port specified on command line, a default
5267 port is selected with the new macro DEFAULT_PORT which is
5268 defined in port.h, in setDefaultOptions() linkOptions is removed
5269 from initialization assignment, since now it is a set,
5270 parseCmdLine uses setParseWithComma for linkOptions, in
5271 linkEdit() linkOptions are accessed with new function indexSet()
5272 which returns the i'th item of a set variable. See SDCCset.c, in
5273 linkEdit() when calling buildCmdLine(), added linkOptions as
5274 last argument. Now users can pass arguments to gplink via the
5275 -Wl option, main() uses pic16glue() to glue up pic16 programs
5276 * src/SDCCpeeph.c: various changes to support pic16
5277 * src/SDCCset.c: added function void *indexSet(set *, int) to

5287 * src/pic16/glue.c: commented out some error producing lines
5288 * src/pic16/main.c: __config directives are commented out to stop
5289 gpasm complaining and test the linkage with gplink, _linkCmd and
5290 _asmCmd changed to be more gplink and gpasm friendly
5291 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5292 produced an error when parsed, peep rule 12 is added to utilize
5293 movff, but it is commented out since the pCode does not support
5294 yet a command with 2 address arguments
5296 2003-05-18 <johan AT balder>
5298 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5325 2003-05-11 Borut Razem <borut.razem AT siol.net>
5327 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5328 the path of bin directory, so that PATH is the only env. variable, which has to be set
5329 in case of standard installation.

6316 2003-01-07 <johan AT balder>
6318 * src/SDCCast.c (decorateType): fixed bug #600035

6333 * src/SDCCicode.c: fixed array add
6335 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6336 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6337 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6339 2003-01-04 <johan AT balder>
6341 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6343 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6344 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6346 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6347 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6356 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6357 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6359 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6361 * in \sdcc\as\mcs51\ changed these files in order to create an
6362 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6363 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6364 following files to include the previous two files: aslink.dsp,
6365 Makefile.aslink, Makefile.bcc, and Makefile.in.
6367 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6368 .adb instead of .cdb
6370 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6372 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6373 value from option --iram-size.
6375 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6377 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6380 2002-09-18 <wiml AT hhhh.org>
6382 * SDCClrange.h: exposed setFromRange() and setToRange()
6383 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6384 packRegsForAccUse() (bug 542397)
6385 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6386 multiple times and emitting the fetch operations more than once
6387 added aopGetUsesAcc() function to allow binary operators to
6388 fetch their operands in the correct order; made genMinus() emit
6389 compact code for X = LITERAL - Y
6391 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6392 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6393 sprintf() in line 1267.
6395 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6396 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6399 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6400 Changes to aslink (All the changes are marked with 'JCF'):
6402 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6405 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6406 area BSEG. Also moves, if possible, the DATA area down into the internal
6407 ram so more space is available.
6409 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6412 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6413 not bytes. Function summary() which creates a memory usage summary
6414 file with extension .mem. Reports of overlaping stack and small stack
6415 size. If the space for the stack is less than 16 bytes aslink trows a
6418 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6419 the 8051. Option 'y' for memory summary output file.
6421 Changes to sdcc (All the changes are marked with 'JCF'):
6423 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6425 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6426 overlaying area for it (uses RegBankUsed[4]).
6428 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6429 bank zero as used by default. By default aslink locates the stack
6430 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6431 the creation of the .mem file. Delegates the allocation of data area
6432 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6433 the begining of the stack area to aslink.
6435 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6436 glue() in SDCCglue.c creates an area for it.
6438 2002-09-03 Borut Razem <borut.razem AT siol.net>
6439 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6440 sdcc/src/pic/glue.c:
6441 introduced atexit() handler for teporay files removal in case of
6442 errors, assertions, ...
6444 2002-08-29 Borut Razem <borut.razem AT siol.net>
6445 * sdcc/support/cpp2/auto-host_vc_in.h:
6446 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6447 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6448 Maybe there is a similar problem with BORLANDC? It should be checked!
6450 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6451 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6452 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6453 was not executed, and the compiler (cl) launched a warning:
6454 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6456 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6457 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6459 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6460 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6462 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6463 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6464 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6465 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6466 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6467 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6468 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6469 - added Release configuration in VS projects
6470 - review of compiler an linker options
6471 - VC .exe files are generated in bin_vc directory, not to interfere
6472 with binaries generated from other projects (cygwin, mingw, bcc ...)
6474 * sdcc/src/yacc.dsp: added
6476 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6477 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6478 and insert the version number definitions from .version
6480 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6482 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6483 added - genarate auto-host.h using auto-host_vc_in.h as template
6486 removed from CVS, generated automatically
6488 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6489 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6491 2002-08-11 Borut Razem <borut.razem AT siol.net>
6492 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6494 2002-08-10 Borut Razem <borut.razem AT siol.net>
6495 * src/SDCCmain.c (main):
6496 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6497 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6498 The consequence was that some temporary files were not removed.
6501 unification of code in functions tempfilename() and tempfile():
6502 function tempnam() is defined in Visual Studio 6.0 and .NET
6504 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6506 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6507 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6508 - removed compiler command line option /WX: Treats all warnings as errors
6509 - update a list of source files, included into the project
6511 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6512 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6513 changed project type to Generic Project so that can be correcly converted to VS.NET project
6515 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6517 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6519 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6521 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6522 added return 0 statements after assert() to make compiler happy
6524 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6525 added newline in the def file to keep MSC compiler satisfied
6527 * sdcc/src/z80/gen.c:
6528 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6529 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6530 - solved MSC error in function aopDump()
6532 * sdcc_vc.h: define PREFIX as "\\sdcc"
6534 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6535 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6537 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6538 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6539 - Rewrote the register banking algorithm.
6540 - Added pCode live-range analysis to registers (for now, only non-used and
6541 singly-used registers optimized away)
6543 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6545 * 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.
6547 2002-05-10 Scott Dattalo <scott AT dattalo.com>
6548 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
6550 2002-04-22 Michael Hope <michaelh AT vroom>
6552 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
