102 Adding support for replacing ljmps with sjmps in jumptables
103 generated for switch statements. For now you need to set the
104 environment variable SDCC_SJMP_JUMPTABLE to enable this.
105 Now 4 algorithms for mcs51 jumptable generation are used:
106 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

137 * (malloc.h): added CVS Id tag,
138 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
140 * added libc directory. The current version of LibC contains string
141 functions, ctype functions and macros and some functions of the
142 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
143 be extensively tested in the future. Standard disclaimer here.
144 Library is not automatically build yet. But one can build it by
145 invoking 'make' inside the libc directory.

156 * (pic16_storeForReturn): optimized return of 0,
157 * (genCmp): experimental code for new genCmp which uses PIC18's
158 special compare&skip instructions. Initial tests fail some times
159 with variables grater than 1 byte in size, so new code is disabled,
160 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
162 * (genCast): began a fix to optimize the casting of a bit to another
163 bit, now assigning a bitfield to another bitfield will fail, sorry,

3153 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3156 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3157 strtof is not part of C89 and isn't included with Mac OS X.
3159 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3186 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3188 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3189 loaded with the linker search paths (-L arguments) and the libraries
3190 to be linked with the current source (-l arguments). Changes
3191 currently will affect only the pic16 port.
3192 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3193 include path the port specific paths and port specific libraries,
3194 * gplink command now contains the $3 argument,
3195 * src/pic16/device.h,
3196 * src/pic16/device.c,: structure PIC_device is made public and
3197 renamed to PIC16_device, the same for variable Pics which is renamed
3198 to Pics16. Updated all references to them.
3199 * src/pic16/glue.c (pic16glue): corrected bug with code
3200 initialization which bypassed the variable initializations block.

3210 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3212 Documenting changes from previous commits.
3213 * configure.in (version 1.56),
3214 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3215 when generating output files to configure the pic16 library,
3216 but now I've commented it out, since gputils aren't installed in the
3217 SF compile farm, so library won't compile
3219 * device/lib/Makefile.in (version 1.56): initially I've added in
3220 target 'all' the prerequestive 'model-pic16' so it compiled the
3221 pic16 library, but now I've commented it out for the same reasons
3223 * added targets 'model-pic16' and 'objects-pic16' to compile the
3225 * added target 'port-specific-objects-pic16' to handle the
3226 generated libraries and copy them into the build/ directory
3227 * added target 'clean-intermediate-pic16' to clean intermediate
3228 files into pic16 directory
3229 * in target 'installdirs' added line to create directory pic16 in
3230 the installation path
3232 * device/include/Makefile.in (version 1.11): in target 'install'
3233 added lines to copy all header files to installation path,
3234 * in target 'installdirs' added line create directory for pic16
3235 headers in the installation path
3237 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3250 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3251 option so that it actually works. Made it specific to the z80, since
3252 the gbz80 doesn't have these kinds of I/O ports.
3254 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3256 * device/include/z180.h,

3269 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3271 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3272 changed interrupt vector table generation to only emit declared vectors.
3273 * device/include/Makefile.in: added missing backslash
3274 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
3276 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3278 Mainly changes to support compilation of the device libraries
3279 * src/pic16/device.c: stack is allocated via symbol and not
3280 via literal number. The symbol is placed in the corresponding
3281 position of the data ram
3282 * (pic16_dump_section): relocatable and absolute uninitialized
3283 data are now emitted in sorted order to reduce section naming,
3284 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3285 weren't marked as being in the access bank,
3287 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3289 Added portion of GNU PIC Library under the directory
3290 device/include/pic16 and device/lib/pic16. These files
3291 contain the declarations of SFRs for the PIC18Fxx2 devices.
3292 The directory is initialized via configure from toplevel.
3294 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3296 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3297 the spilllocations to be compared correctly
3299 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3301 * src/SDCCast.c (decorateType): fixed bug introduced today
3303 2004-01-12 Borut Razem <borut.razem AT siol.net>
3305 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3308 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3310 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3311 in simpler and even better code
3313 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3315 * src/SDCCicode.c (operandOperation): fixed bug #874819

3319 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3321 * doc/sdccman.lyx: Moved and added some sections, small changes
3322 all over. Telling LaTeX to be less strict with word spacing
3323 to better keep the right margin. Changed some notes about
3324 maintainance of the ports in section 3.2.1 - is it OK like this?
3326 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3328 SDCC source changes:
3329 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3362 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
3363 UPPER for immediate operands,
3364 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3366 * src/pic16/peeph.def: all peepholes with movff are commented out,
3367 because there is a problem in the pcode peep optimizer,
3368 * src/pic16/ralloc.c: the register allocator can now reuse local
3369 function symbols for another function. This saves register usage.
3370 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3372 Added file src/pic16/NOTES with information about program writing on
3373 the current port version.

3382 * src/SDCCmain.c : fixed #872250: -l command line defined library
3383 files are scanned before standard library files
3385 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3402 gen51Code): more efficient parameter receive for --model-large
3405 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3408 * src/z80/main.c: added missed needLinkerScript flags (more than
3409 one port structure defined in these file)
3410 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
3413 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

3426 needLinkerScript flag
3428 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3429 * src/pic/glue.c: added variable udata_section_name to
3430 override default uninitialized data segment definition for
3431 devices only with SHAREBANK memory (reported from Erik Epetrich)
3432 * (pic14emitOverlay): modified to emit a commented overlay segment
3433 directive when no overlay data exist
3434 * (picglue): modified to emit uninitialized data segment
3435 according to udata_section_name

3440 arguments via -W option
3441 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3442 object file from '.rel' to '.o' in port->linker structure,
3443 changed size of fptr from 2 to 3 in port structure
3445 2004-01-07 Borut Razem <borut.razem AT siol.net>
3447 * support/scripts/sdcc.nsi: update PATH
3448 * support/scripts/sdcc.ico: craeted
3450 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
3452 * device/include/Makefile.in: fix install
3453 * doc/Makefile: fix install
3455 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3457 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3459 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3460 how the function variable allocation summary is displayed; also
3461 include information about variables allocated to the overlay
3464 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3466 * as/mcs51/lkmain.c: Help about -Y option

3478 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3480 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3481 (default behaviour).
3483 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3485 A python script to validate compiler diagnostic messages. It can be
3486 used to verify that sdcc complains about bad c source code and
3487 gives a good location of the error.
3488 * support/valdiag/Makefile,
3489 * support/valdiag/valdiag.py,
3490 * support/valdiag/tests/*
3492 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3494 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3495 * src/SDCCsymt.c (newEnumType),

3503 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3505 * src/common.h: added ifndef/define/endif macros
3506 around the header file.
3507 Bug reported from Jesus Calvino-Fraga
3509 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3511 * sdcc.spec: updated
3512 * device/include/Makefile.in: don't install CVS directories
3513 * device/lib/Makefile.in: added removal of CVS directories after install
3514 * doc/Makefile: fixed install, added local_icons
3515 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3516 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3517 * src/ds390/gen.c (genRightShift): fixed bug #870788
3518 * src/SDCCast.c (decorateType): fixed bug #870781
3520 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3522 PIC16 port related changes:
3523 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3524 added variable stackPos,
3526 * gen.c: genCall, assignResultValue: added support for
3527 pushing/retrieving function parameters to/from stack,
3528 genFunction,genEndFunction: setup stack frame for the
3530 genAddrOf: will be changed according to bug 863624
3532 * added files genutils.c and genutils.h which contain gen*
3533 debugged and optimised functions extracted from gen.c
3535 * glue.c: added variable 'externs' which holds extern symbols,
3536 pic16emitRegularMap: is modified to properly handle relocatable
3537 symbols under the new scheme,
3538 pic16createInterruptVect: is modified
3539 pic16printPublics: is modified to emit 'global' assembler directives,
3540 added pic16_printExterns to print extern symbols,
3541 pic16glue: initializes stack/frame pointer in the beginning of
3542 the assembly output. Temporary hack, will be corrected later,
3543 because gplink yet does not support stack and SDCC does not
3544 yet support a type of crt0.o object to create the final binary.
3546 * Removed many lines that contain 8051 legacy code.
3547 * The code is finally placed under a 'code' directive.
3548 * Added port specific options.
3550 * _process_pragma: simplified since now we do not need *special*
3551 include file to define SFR registers. But a separate header
3552 will be needed. This will be developed later.
3553 * _pic16_parseOptions: added, parses port specific options:
3554 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3555 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3556 --preplace-udata-with=
3558 * _pic16_setDefaultOptions: modified to initialize section names,
3559 but hack is temporarly out of order since it needs improvement.
3560 * _pic16_genAssemblerPreamble: configuration words are emitted by
3561 their address instead of their name. This part is incomplete and
3562 supports only the 18Fxx2 devices. Other devices will emit an error
3563 during assembly since they do not contain the same set of config
3565 * _pic16_genIVT: is modified,
3567 * pcode.c: added definitions for some hardware registers that are needed
3569 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3570 All PCI entries are updated. Now LFSR is supported.
3571 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3572 * added pic16_newpCodeOpLit2 to support instructions with
3573 two literal arguments
3574 * pic16_pCode2str: corrected code that emits assembler instructions
3575 with two literal operands and those that have an access bit modifier
3576 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3577 this fixes a bug which caused some labels to be lost, when an
3578 assembler directive was added, i.e. banksel,
3579 * pic16_FixRegisterBanking: improved logic that causes the insertion
3581 * InlineFunction: functions that are called once, are not any more
3582 inlined. This can be a port option in the future,
3584 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3586 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3587 hold the corresponding uninitialized symbols,
3588 * pic16_allocProcessorRegister: registers have explicit marked the
3590 * pic16_allocInternalRegister: registers are explicit marked as
3592 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3593 processing list, so bit registers were lost,
3596 * ralloc.h: added field 'accessBank' and original symbol operand
3597 in register definition,
3598 * removed the field isMapped from register definition,
3600 ** Several functions have been removed from various sources:
3601 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3602 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3603 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3604 pic16_assignRelocatableRegisters
3606 ** others have been introduced:
3607 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3608 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3610 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3612 * support/scripts/inc2h.pl: changed definition of BIT_AT
3613 to emit 'sbit at' instead of 'bit at'. This was a request.
3615 PIC16 port related preliminary changes:
3616 * gen.c: prefixed function popRegFromString with
3617 pic16_ and all references to it corrected
3618 * pcode.c: all pic16_pc_* hardware registers prefixed
3619 with underscore (_),
3620 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3621 * ralloc.c: newReg(): when register is REG_SFR then
3622 set address to rIdx,
3623 pic16_allocProcessorRegister(): marks register wasUsed=0
3624 pic16_writeUsedRegs(): added a call to assign processor
3625 registers via pic16_assignFixedRegisters
3627 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3629 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3630 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3631 variables in unused register banks. Also the SSEG is placed
3632 wherever there is enough space for it, and IDATA can be anywhere
3633 in internal RAM. For now compile using -Wl-Y[stack_size].
3634 The mem file is different for this option as well, since it
3635 makes no sense of talking about DSEG lenght.

4633 iCode properly now. Use getSize instead of nRegs since a & b
4634 aren't part of the nRegs tally.
4636 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
4638 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
4639 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
4640 before instructions that use the _STATUS register
4642 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
4644 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4645 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4646 fetching of the pointer
4647 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4648 copied from genNearPointerSet()
4649 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4650 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4651 If they pop r0/r1 they must be called in the opposite order than aopOp().
4652 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4653 (resp. --stack-auto), prepared for --xstack

4662 these ports have their own __sdcc_external_start()
4664 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4666 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4667 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4668 type for bits was changed. It resulted in bit variables becoming
4669 global, which is not permitted in PIC 14 assembly output.
4671 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4673 * doc/sdccman.lyx: various additions and updates. Rearranged sections
4675 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4677 Z80 and MCS51 linkers complaint if a public symbol is defined

4686 A few small changes that speed up the peephole optimizer.
4690 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4692 Try to make the peephole optimizer smarter by maintaining
4693 an association between the assembly source code and the
4694 iCodes that originated them. Put this information to use
4695 with a new peephole rule condition "notVolatile" so that
4696 the rules can be aggressive yet still safe.
4701 * src/mcs51/peeph.def
4703 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4707 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4708 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4709 if the left or right operand symbols have the accuse flag set.
4711 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4713 Changed the type of the result of the ! (NOT) operator to char;
4714 previously it returned the same type as the source. This allows
4715 us to eliminate all the genFloatNot functions (all of its target
4716 implementations were very buggy) since !float can use the same
4719 * src/SDCCicode.c (ast2iCode): ! returns char

4728 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4729 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4730 during interrupts. Ensure WSAVE is located at a shared bank address.
4731 2. Fixed page selection in some places
4732 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4733 the registers name strings.
4734 4. Fixed "signed / unsigned compare" compiler warnings.
4735 5. The PIC port manages its own allocation of the general purpose
4736 registers, but makes no attempt to reuse them. As a result when
4737 compiling it soon runs out of general purpose registers. Some
4738 additional code was added to the files pcode.c and device.c to walk
4739 through the function call tree and rename the registers so that they
4749 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4750 genPlus() & genMinus() when the result is the same as left or right

4756 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4758 Made bitfield a distinct type from bit so that bitfields
4759 convert as per ANSI C and bits retain their traditional
4760 boolean style behaviour. Implemented bitfield support in
4768 * src/ds390/gen.c: bit v bitfield split
4769 * src/z80/gen.c: New support for bitfields
4770 * support/regression/tests/bitfields.c: reenabled z80,
4773 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4775 Rules 246.x, 247.x relate to bitfields, the others speed up
4776 access to xdata mapped I/O devices.
4778 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4780 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4782 Cleaned up genPackBits and genUnpackBits and added two helper
4783 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4784 for literal assignments in genPackBits (thanks to Frieder for
4790 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4792 Fixed bug #748310 (pointer to function type mishandled when the
4793 function name is omitted). Also fixed a SIGSEGV when a function
4794 attribute (reentrant, etc) is used on a non-function or on a
4795 function but misplaced before the parameter list.
4797 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4799 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4800 * support/Util/SDCCerr.h,

4822 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4824 Made the constant following the "interrupt" keyword optional. If
4825 omitted, the function will not automatically be given an entry
4826 in the interrupt vector table (similar to #pragma NOIV, but
4827 less syntacticly kludgy). The interrupt number is also now
4828 range checked. Also fixed a bug in the high order bit example

4844 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4846 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4847 be re-activated by defining REDUCE_LITERALS)
4848 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4849 unsigned, but are signed by default
4850 * src/SDCCval.c (constVal): rearranged
4851 * src/SDCCval.c (valMod): preliminary fix
4852 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5304 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5305 the regression tests I'm not brave enough to enable 245.b, 245.c
5306 * doc/sdccman.lyx: added latex preamble for hyperref package.
5307 Using pdflatex this will give you a hyperlinked pdf file with
5308 bookmarks. (prepend '%' before /usepackage if this breaks something)

5324 Applied patch from bug 737905 (renamed yylineo to mylineno):
5331 * src/pic16/pcode.c: Cleaned warnings
5332 * src/pic16/pcodeflow.c: Cleaned warnings
5333 * src/pic16/pcoderegs.c: Cleaned warnings

5349 it can be defined with CFLAGS when running configure
5350 * src/SDCCmain.c: fixed compiling + linking with object files
5352 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5355 added --disable-pic16-port
5356 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5357 * src/SDCCmain.c: linkOptions is changed to set *,
5358 added if/endif conditional macros to remove options help
5359 messages from optionsTable when a port is not configured, added
5360 support for the PIc16 port in the ports table, when executing
5361 the compiler with no port specified on command line, a default
5362 port is selected with the new macro DEFAULT_PORT which is
5363 defined in port.h, in setDefaultOptions() linkOptions is removed
5364 from initialization assignment, since now it is a set,
5365 parseCmdLine uses setParseWithComma for linkOptions, in
5366 linkEdit() linkOptions are accessed with new function indexSet()
5367 which returns the i'th item of a set variable. See SDCCset.c, in
5368 linkEdit() when calling buildCmdLine(), added linkOptions as
5369 last argument. Now users can pass arguments to gplink via the
5370 -Wl option, main() uses pic16glue() to glue up pic16 programs

5382 * src/pic16/glue.c: commented out some error producing lines
5383 * src/pic16/main.c: __config directives are commented out to stop
5384 gpasm complaining and test the linkage with gplink, _linkCmd and
5385 _asmCmd changed to be more gplink and gpasm friendly
5386 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5387 produced an error when parsed, peep rule 12 is added to utilize
5388 movff, but it is commented out since the pCode does not support
5389 yet a command with 2 address arguments
5391 2003-05-18 <johan AT balder>
5393 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5394 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5418 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5420 2003-05-11 Borut Razem <borut.razem AT siol.net>
5422 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5423 the path of bin directory, so that PATH is the only env. variable, which has to be set
5424 in case of standard installation.
5425 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6454 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6456 * in \sdcc\as\mcs51\ changed these files in order to create an
6457 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6458 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6459 following files to include the previous two files: aslink.dsp,
6460 Makefile.aslink, Makefile.bcc, and Makefile.in.
6462 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6463 .adb instead of .cdb
6465 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6467 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6468 value from option --iram-size.
6470 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6472 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6475 2002-09-18 <wiml AT hhhh.org>
6477 * SDCClrange.h: exposed setFromRange() and setToRange()
6478 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6479 packRegsForAccUse() (bug 542397)
6480 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6481 multiple times and emitting the fetch operations more than once
6482 added aopGetUsesAcc() function to allow binary operators to
6483 fetch their operands in the correct order; made genMinus() emit
6484 compact code for X = LITERAL - Y
6486 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6487 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6488 sprintf() in line 1267.
6490 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6491 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6494 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6495 Changes to aslink (All the changes are marked with 'JCF'):
6497 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6500 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6501 area BSEG. Also moves, if possible, the DATA area down into the internal
6502 ram so more space is available.
6504 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6507 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6508 not bytes. Function summary() which creates a memory usage summary
6509 file with extension .mem. Reports of overlaping stack and small stack
6510 size. If the space for the stack is less than 16 bytes aslink trows a
6513 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6514 the 8051. Option 'y' for memory summary output file.
6516 Changes to sdcc (All the changes are marked with 'JCF'):
6518 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6520 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6521 overlaying area for it (uses RegBankUsed[4]).
6523 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6524 bank zero as used by default. By default aslink locates the stack
6525 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6526 the creation of the .mem file. Delegates the allocation of data area
6527 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6528 the begining of the stack area to aslink.
6530 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6531 glue() in SDCCglue.c creates an area for it.
6533 2002-09-03 Borut Razem <borut.razem AT siol.net>
6534 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6535 sdcc/src/pic/glue.c:
6536 introduced atexit() handler for teporay files removal in case of
6537 errors, assertions, ...
6539 2002-08-29 Borut Razem <borut.razem AT siol.net>
6540 * sdcc/support/cpp2/auto-host_vc_in.h:
6541 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6542 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6543 Maybe there is a similar problem with BORLANDC? It should be checked!
6545 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6546 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6547 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6548 was not executed, and the compiler (cl) launched a warning:
6549 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6551 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6557 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6558 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6559 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6560 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6561 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6562 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6563 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6564 - added Release configuration in VS projects
6565 - review of compiler an linker options
6566 - VC .exe files are generated in bin_vc directory, not to interfere
6567 with binaries generated from other projects (cygwin, mingw, bcc ...)
6569 * sdcc/src/yacc.dsp: added
6571 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6572 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6573 and insert the version number definitions from .version
6575 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6577 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6587 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6589 2002-08-10 Borut Razem <borut.razem AT siol.net>
6590 * src/SDCCmain.c (main):
6591 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6592 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6593 The consequence was that some temporary files were not removed.
6596 unification of code in functions tempfilename() and tempfile():
6597 function tempnam() is defined in Visual Studio 6.0 and .NET
6599 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6601 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6602 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6603 - removed compiler command line option /WX: Treats all warnings as errors
6604 - update a list of source files, included into the project

6616 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6617 added return 0 statements after assert() to make compiler happy
6619 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6620 added newline in the def file to keep MSC compiler satisfied
6622 * sdcc/src/z80/gen.c:
6623 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6624 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6625 - solved MSC error in function aopDump()
6627 * sdcc_vc.h: define PREFIX as "\\sdcc"
6629 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

6681 Initialized the new field char *Processor field to NULL in all ports
6684 Compiler generated registers for interrupt context saving
6685 were not getting allocated.
6687 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6690 Fixed left shift. Will promote the left side of a left shift
6691 if a) left shifting more than size of operand or b) when assigned
6692 to something size > size of left side
6694 2002-03-14 Scott Dattalo <scott AT dattalo.com>

6802 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6804 * sdcc/src/SDCCloop.c:
6805 Previous fix was not good. basic blocks that have "break" or "return" are
6806 not really partof a loop , but live ranges used in these blocks should
6807 be live thru the entire loop, so set partOfLoop but don't add them to
6810 2002-02-21 <johan AT FRIJA>
