514 Adding support for replacing ljmps with sjmps in jumptables
515 generated for switch statements. For now you need to set the
516 environment variable SDCC_SJMP_JUMPTABLE to enable this.
517 Now 4 algorithms for mcs51 jumptable generation are used:
518 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
519 addresses loaded pc-relative for up to 112 cases and stack-pushing
520 target addresses loaded with offset from dptr for up to 256 cases.

547 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
548 to call when a stack overflow occurs,
549 * (malloc.h): added CVS Id tag,
550 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
552 * added libc directory. The current version of LibC contains string
553 functions, ctype functions and macros and some functions of the
554 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
555 be extensively tested in the future. Standard disclaimer here.
556 Library is not automatically build yet. But one can build it by
557 invoking 'make' inside the libc directory.
558 * added ADC library under libio. Preliminary version yet.
560 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

568 * (pic16_storeForReturn): optimized return of 0,
569 * (genCmp): experimental code for new genCmp which uses PIC18's
570 special compare&skip instructions. Initial tests fail some times
571 with variables grater than 1 byte in size, so new code is disabled,
572 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
574 * (genCast): began a fix to optimize the casting of a bit to another
575 bit, now assigning a bitfield to another bitfield will fail, sorry,
576 * src/pic16/main.c: disabled the use of lr-support feature,
577 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

580 bits with offset (case PO_GPR_BIT),
581 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
583 * (isBankInstruction): modified to return 0 for no banking instruction,
584 and 1 for banking instruction,
585 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
586 caused stop processing pCodes after a inline assembly block,
587 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
588 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
589 registers when it shouldn't,
590 * src/pic16/ralloc.c (allocReg): add preliminary support for
591 supporting a limited set of temporary registers,
593 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
595 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
596 genDataPointerSet): ensure assignments always copy in MSB to LSB
598 (loadRegFromAop): recognize CLRH optimization,
599 (genFunction): optimize RECEIVE iCodes in reentrant functions
601 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
603 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
604 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

3598 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3600 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3601 loaded with the linker search paths (-L arguments) and the libraries
3602 to be linked with the current source (-l arguments). Changes
3603 currently will affect only the pic16 port.
3604 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3605 include path the port specific paths and port specific libraries,
3606 * gplink command now contains the $3 argument,
3607 * src/pic16/device.h,
3608 * src/pic16/device.c,: structure PIC_device is made public and
3609 renamed to PIC16_device, the same for variable Pics which is renamed
3610 to Pics16. Updated all references to them.
3611 * src/pic16/glue.c (pic16glue): corrected bug with code
3612 initialization which bypassed the variable initializations block.

3622 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3624 Documenting changes from previous commits.
3625 * configure.in (version 1.56),
3626 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3627 when generating output files to configure the pic16 library,
3628 but now I've commented it out, since gputils aren't installed in the
3629 SF compile farm, so library won't compile
3631 * device/lib/Makefile.in (version 1.56): initially I've added in
3632 target 'all' the prerequestive 'model-pic16' so it compiled the
3633 pic16 library, but now I've commented it out for the same reasons
3635 * added targets 'model-pic16' and 'objects-pic16' to compile the
3637 * added target 'port-specific-objects-pic16' to handle the
3638 generated libraries and copy them into the build/ directory
3639 * added target 'clean-intermediate-pic16' to clean intermediate
3640 files into pic16 directory
3641 * in target 'installdirs' added line to create directory pic16 in
3642 the installation path
3644 * device/include/Makefile.in (version 1.11): in target 'install'
3645 added lines to copy all header files to installation path,
3646 * in target 'installdirs' added line create directory for pic16
3647 headers in the installation path

3662 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3663 option so that it actually works. Made it specific to the z80, since
3664 the gbz80 doesn't have these kinds of I/O ports.
3666 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3668 * device/include/z180.h,

3681 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3683 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3684 changed interrupt vector table generation to only emit declared vectors.
3685 * device/include/Makefile.in: added missing backslash
3686 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

3690 Mainly changes to support compilation of the device libraries
3691 * src/pic16/device.c: stack is allocated via symbol and not
3692 via literal number. The symbol is placed in the corresponding
3693 position of the data ram
3694 * (pic16_dump_section): relocatable and absolute uninitialized
3695 data are now emitted in sorted order to reduce section naming,
3696 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3697 weren't marked as being in the access bank,
3699 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3701 Added portion of GNU PIC Library under the directory
3702 device/include/pic16 and device/lib/pic16. These files
3703 contain the declarations of SFRs for the PIC18Fxx2 devices.
3704 The directory is initialized via configure from toplevel.
3706 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3708 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3709 the spilllocations to be compared correctly
3711 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3713 * src/SDCCast.c (decorateType): fixed bug introduced today
3715 2004-01-12 Borut Razem <borut.razem AT siol.net>
3717 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3720 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3722 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3723 in simpler and even better code
3725 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3727 * src/SDCCicode.c (operandOperation): fixed bug #874819

3733 * doc/sdccman.lyx: Moved and added some sections, small changes
3734 all over. Telling LaTeX to be less strict with word spacing
3735 to better keep the right margin. Changed some notes about
3736 maintainance of the ports in section 3.2.1 - is it OK like this?
3738 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3740 SDCC source changes:
3741 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3774 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
3775 UPPER for immediate operands,
3776 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3778 * src/pic16/peeph.def: all peepholes with movff are commented out,
3779 because there is a problem in the pcode peep optimizer,
3780 * src/pic16/ralloc.c: the register allocator can now reuse local
3781 function symbols for another function. This saves register usage.
3782 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3784 Added file src/pic16/NOTES with information about program writing on
3785 the current port version.

3794 * src/SDCCmain.c : fixed #872250: -l command line defined library
3795 files are scanned before standard library files
3797 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3814 gen51Code): more efficient parameter receive for --model-large
3817 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3820 * src/z80/main.c: added missed needLinkerScript flags (more than
3821 one port structure defined in these file)
3822 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3838 needLinkerScript flag
3840 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3841 * src/pic/glue.c: added variable udata_section_name to
3842 override default uninitialized data segment definition for
3843 devices only with SHAREBANK memory (reported from Erik Epetrich)
3844 * (pic14emitOverlay): modified to emit a commented overlay segment
3845 directive when no overlay data exist
3846 * (picglue): modified to emit uninitialized data segment
3847 according to udata_section_name

3853 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3854 object file from '.rel' to '.o' in port->linker structure,
3855 changed size of fptr from 2 to 3 in port structure
3857 2004-01-07 Borut Razem <borut.razem AT siol.net>
3859 * support/scripts/sdcc.nsi: update PATH
3860 * support/scripts/sdcc.ico: craeted
3862 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3865 * doc/Makefile: fix install
3867 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3869 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3871 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

3873 include information about variables allocated to the overlay
3876 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3878 * as/mcs51/lkmain.c: Help about -Y option

3890 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3892 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3893 (default behaviour).
3895 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3897 A python script to validate compiler diagnostic messages. It can be
3898 used to verify that sdcc complains about bad c source code and
3899 gives a good location of the error.
3900 * support/valdiag/Makefile,
3901 * support/valdiag/valdiag.py,
3902 * support/valdiag/tests/*
3904 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3906 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3907 * src/SDCCsymt.c (newEnumType),

3915 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3917 * src/common.h: added ifndef/define/endif macros
3918 around the header file.
3919 Bug reported from Jesus Calvino-Fraga
3921 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3923 * sdcc.spec: updated
3924 * device/include/Makefile.in: don't install CVS directories
3925 * device/lib/Makefile.in: added removal of CVS directories after install
3926 * doc/Makefile: fixed install, added local_icons
3927 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3928 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3929 * src/ds390/gen.c (genRightShift): fixed bug #870788
3930 * src/SDCCast.c (decorateType): fixed bug #870781
3932 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3934 PIC16 port related changes:
3935 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3936 added variable stackPos,
3938 * gen.c: genCall, assignResultValue: added support for
3939 pushing/retrieving function parameters to/from stack,
3940 genFunction,genEndFunction: setup stack frame for the
3942 genAddrOf: will be changed according to bug 863624
3944 * added files genutils.c and genutils.h which contain gen*
3945 debugged and optimised functions extracted from gen.c
3947 * glue.c: added variable 'externs' which holds extern symbols,
3948 pic16emitRegularMap: is modified to properly handle relocatable
3949 symbols under the new scheme,
3950 pic16createInterruptVect: is modified
3951 pic16printPublics: is modified to emit 'global' assembler directives,
3952 added pic16_printExterns to print extern symbols,
3953 pic16glue: initializes stack/frame pointer in the beginning of
3954 the assembly output. Temporary hack, will be corrected later,
3955 because gplink yet does not support stack and SDCC does not
3956 yet support a type of crt0.o object to create the final binary.
3958 * Removed many lines that contain 8051 legacy code.
3959 * The code is finally placed under a 'code' directive.
3960 * Added port specific options.
3962 * _process_pragma: simplified since now we do not need *special*
3963 include file to define SFR registers. But a separate header
3964 will be needed. This will be developed later.
3965 * _pic16_parseOptions: added, parses port specific options:
3966 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3967 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3968 --preplace-udata-with=
3970 * _pic16_setDefaultOptions: modified to initialize section names,
3971 but hack is temporarly out of order since it needs improvement.
3972 * _pic16_genAssemblerPreamble: configuration words are emitted by
3973 their address instead of their name. This part is incomplete and
3974 supports only the 18Fxx2 devices. Other devices will emit an error
3975 during assembly since they do not contain the same set of config
3977 * _pic16_genIVT: is modified,
3979 * pcode.c: added definitions for some hardware registers that are needed
3981 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3982 All PCI entries are updated. Now LFSR is supported.
3983 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3984 * added pic16_newpCodeOpLit2 to support instructions with
3985 two literal arguments
3986 * pic16_pCode2str: corrected code that emits assembler instructions
3987 with two literal operands and those that have an access bit modifier
3988 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3989 this fixes a bug which caused some labels to be lost, when an
3990 assembler directive was added, i.e. banksel,
3991 * pic16_FixRegisterBanking: improved logic that causes the insertion
3993 * InlineFunction: functions that are called once, are not any more
3994 inlined. This can be a port option in the future,
3996 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3998 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3999 hold the corresponding uninitialized symbols,
4000 * pic16_allocProcessorRegister: registers have explicit marked the
4002 * pic16_allocInternalRegister: registers are explicit marked as
4004 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4005 processing list, so bit registers were lost,
4008 * ralloc.h: added field 'accessBank' and original symbol operand
4009 in register definition,
4010 * removed the field isMapped from register definition,
4012 ** Several functions have been removed from various sources:
4013 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4014 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4015 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4016 pic16_assignRelocatableRegisters
4018 ** others have been introduced:
4019 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4020 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4022 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4024 * support/scripts/inc2h.pl: changed definition of BIT_AT
4025 to emit 'sbit at' instead of 'bit at'. This was a request.
4027 PIC16 port related preliminary changes:
4028 * gen.c: prefixed function popRegFromString with
4029 pic16_ and all references to it corrected
4030 * pcode.c: all pic16_pc_* hardware registers prefixed
4031 with underscore (_),
4032 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4033 * ralloc.c: newReg(): when register is REG_SFR then
4034 set address to rIdx,
4035 pic16_allocProcessorRegister(): marks register wasUsed=0
4036 pic16_writeUsedRegs(): added a call to assign processor
4037 registers via pic16_assignFixedRegisters
4039 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4041 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4042 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4043 variables in unused register banks. Also the SSEG is placed
4044 wherever there is enough space for it, and IDATA can be anywhere
4045 in internal RAM. For now compile using -Wl-Y[stack_size].
4046 The mem file is different for this option as well, since it
4047 makes no sense of talking about DSEG lenght.
4049 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4051 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4052 in certain cases, e.g. when ROM assignment, patch provided
4053 from Albert den Haan.
4055 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4061 (usualBinaryConversions): added support for promotion of char
4062 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)
4063 (geniCodeDivision): replaced (unsigned long) by (TYPE_UDWORD)

4066 (geniCodeArray): ditto
4067 * src/SDCCicode.h: made geniCodeCast() static: removed prototype
4068 * src/SDCCsymt.c (computeType): added more support for char;

5062 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5063 If they pop r0/r1 they must be called in the opposite order than aopOp().
5064 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5065 (resp. --stack-auto), prepared for --xstack

5074 these ports have their own __sdcc_external_start()
5076 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5078 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5079 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5080 type for bits was changed. It resulted in bit variables becoming
5081 global, which is not permitted in PIC 14 assembly output.
5083 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5085 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5087 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5089 Z80 and MCS51 linkers complaint if a public symbol is defined

5098 A few small changes that speed up the peephole optimizer.
5102 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5104 Try to make the peephole optimizer smarter by maintaining
5105 an association between the assembly source code and the
5106 iCodes that originated them. Put this information to use
5107 with a new peephole rule condition "notVolatile" so that
5108 the rules can be aggressive yet still safe.
5113 * src/mcs51/peeph.def
5115 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5119 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5120 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5121 if the left or right operand symbols have the accuse flag set.
5123 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5125 Changed the type of the result of the ! (NOT) operator to char;
5126 previously it returned the same type as the source. This allows
5127 us to eliminate all the genFloatNot functions (all of its target
5128 implementations were very buggy) since !float can use the same
5131 * src/SDCCicode.c (ast2iCode): ! returns char

5133 * src/ds390/gen.c (genNot, genNotFloat),
5134 * src/z80/gen.c (genNot, genNotFloat),
5135 * src/pic/gen.c (genNot, genNotFloat),

5140 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5141 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5142 during interrupts. Ensure WSAVE is located at a shared bank address.
5143 2. Fixed page selection in some places
5144 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5145 the registers name strings.
5146 4. Fixed "signed / unsigned compare" compiler warnings.
5147 5. The PIC port manages its own allocation of the general purpose
5148 registers, but makes no attempt to reuse them. As a result when
5149 compiling it soon runs out of general purpose registers. Some
5150 additional code was added to the files pcode.c and device.c to walk
5151 through the function call tree and rename the registers so that they
5161 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5162 genPlus() & genMinus() when the result is the same as left or right

5168 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5170 Made bitfield a distinct type from bit so that bitfields
5171 convert as per ANSI C and bits retain their traditional
5172 boolean style behaviour. Implemented bitfield support in
5180 * src/ds390/gen.c: bit v bitfield split
5181 * src/z80/gen.c: New support for bitfields
5182 * support/regression/tests/bitfields.c: reenabled z80,
5185 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5187 Rules 246.x, 247.x relate to bitfields, the others speed up
5188 access to xdata mapped I/O devices.
5190 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5192 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5194 Cleaned up genPackBits and genUnpackBits and added two helper
5195 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5196 for literal assignments in genPackBits (thanks to Frieder for
5202 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5204 Fixed bug #748310 (pointer to function type mishandled when the
5205 function name is omitted). Also fixed a SIGSEGV when a function
5206 attribute (reentrant, etc) is used on a non-function or on a
5207 function but misplaced before the parameter list.
5209 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5211 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5234 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5236 Made the constant following the "interrupt" keyword optional. If
5237 omitted, the function will not automatically be given an entry
5238 in the interrupt vector table (similar to #pragma NOIV, but
5239 less syntacticly kludgy). The interrupt number is also now
5240 range checked. Also fixed a bug in the high order bit example
5247 * support/Util/SDCCerr.c
5248 * support/Util/SDCCerr.h
5251 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5254 * src/SDCCicode.c (operandOperation): rewritten some ops
5255 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5256 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5258 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5259 be re-activated by defining REDUCE_LITERALS)
5260 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5261 unsigned, but are signed by default
5262 * src/SDCCval.c (constVal): rearranged
5263 * src/SDCCval.c (valMod): preliminary fix
5264 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5716 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5717 the regression tests I'm not brave enough to enable 245.b, 245.c
5718 * doc/sdccman.lyx: added latex preamble for hyperref package.
5719 Using pdflatex this will give you a hyperlinked pdf file with
5720 bookmarks. (prepend '%' before /usepackage if this breaks something)

5761 it can be defined with CFLAGS when running configure
5762 * src/SDCCmain.c: fixed compiling + linking with object files
5764 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5767 added --disable-pic16-port
5768 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5769 * src/SDCCmain.c: linkOptions is changed to set *,
5770 added if/endif conditional macros to remove options help
5771 messages from optionsTable when a port is not configured, added
5772 support for the PIc16 port in the ports table, when executing
5773 the compiler with no port specified on command line, a default
5774 port is selected with the new macro DEFAULT_PORT which is
5775 defined in port.h, in setDefaultOptions() linkOptions is removed
5776 from initialization assignment, since now it is a set,
5777 parseCmdLine uses setParseWithComma for linkOptions, in
5778 linkEdit() linkOptions are accessed with new function indexSet()
5779 which returns the i'th item of a set variable. See SDCCset.c, in
5780 linkEdit() when calling buildCmdLine(), added linkOptions as
5781 last argument. Now users can pass arguments to gplink via the
5782 -Wl option, main() uses pic16glue() to glue up pic16 programs
5783 * src/SDCCpeeph.c: various changes to support pic16

5794 * src/pic16/glue.c: commented out some error producing lines
5795 * src/pic16/main.c: __config directives are commented out to stop
5796 gpasm complaining and test the linkage with gplink, _linkCmd and
5797 _asmCmd changed to be more gplink and gpasm friendly
5798 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5799 produced an error when parsed, peep rule 12 is added to utilize
5800 movff, but it is commented out since the pCode does not support
5801 yet a command with 2 address arguments
5803 2003-05-18 <johan AT balder>
5805 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5806 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5830 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5832 2003-05-11 Borut Razem <borut.razem AT siol.net>
5834 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5835 the path of bin directory, so that PATH is the only env. variable, which has to be set
5836 in case of standard installation.
5837 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6866 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6868 * in \sdcc\as\mcs51\ changed these files in order to create an
6869 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6870 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6871 following files to include the previous two files: aslink.dsp,
6872 Makefile.aslink, Makefile.bcc, and Makefile.in.
6874 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6875 .adb instead of .cdb
6877 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6879 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6880 value from option --iram-size.
6882 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6884 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6887 2002-09-18 <wiml AT hhhh.org>
6889 * SDCClrange.h: exposed setFromRange() and setToRange()
6890 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6891 packRegsForAccUse() (bug 542397)
6892 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6893 multiple times and emitting the fetch operations more than once
6894 added aopGetUsesAcc() function to allow binary operators to
6895 fetch their operands in the correct order; made genMinus() emit
6896 compact code for X = LITERAL - Y
6898 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6899 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6900 sprintf() in line 1267.
6902 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6903 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6906 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6907 Changes to aslink (All the changes are marked with 'JCF'):
6909 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6912 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6913 area BSEG. Also moves, if possible, the DATA area down into the internal
6914 ram so more space is available.
6916 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6919 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6920 not bytes. Function summary() which creates a memory usage summary
6921 file with extension .mem. Reports of overlaping stack and small stack
6922 size. If the space for the stack is less than 16 bytes aslink trows a
6925 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6926 the 8051. Option 'y' for memory summary output file.
6928 Changes to sdcc (All the changes are marked with 'JCF'):
6930 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6932 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6933 overlaying area for it (uses RegBankUsed[4]).
6935 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6936 bank zero as used by default. By default aslink locates the stack
6937 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6938 the creation of the .mem file. Delegates the allocation of data area
6939 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6940 the begining of the stack area to aslink.
6942 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6943 glue() in SDCCglue.c creates an area for it.
6945 2002-09-03 Borut Razem <borut.razem AT siol.net>
6946 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6947 sdcc/src/pic/glue.c:
6948 introduced atexit() handler for teporay files removal in case of
6949 errors, assertions, ...
6951 2002-08-29 Borut Razem <borut.razem AT siol.net>
6952 * sdcc/support/cpp2/auto-host_vc_in.h:
6953 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6954 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6955 Maybe there is a similar problem with BORLANDC? It should be checked!
6957 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6958 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6959 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6960 was not executed, and the compiler (cl) launched a warning:
6961 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6963 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6964 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6966 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

6975 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6976 - added Release configuration in VS projects
6977 - review of compiler an linker options
6978 - VC .exe files are generated in bin_vc directory, not to interfere
6979 with binaries generated from other projects (cygwin, mingw, bcc ...)
6981 * sdcc/src/yacc.dsp: added
6983 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6984 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6985 and insert the version number definitions from .version
6987 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6989 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6993 removed from CVS, generated automatically
6995 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6996 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6998 2002-08-11 Borut Razem <borut.razem AT siol.net>
6999 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7001 2002-08-10 Borut Razem <borut.razem AT siol.net>
7002 * src/SDCCmain.c (main):
7003 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7004 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7005 The consequence was that some temporary files were not removed.
7008 unification of code in functions tempfilename() and tempfile():
7009 function tempnam() is defined in Visual Studio 6.0 and .NET
7011 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7013 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7014 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7015 - removed compiler command line option /WX: Treats all warnings as errors
7016 - update a list of source files, included into the project
7018 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7019 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7020 changed project type to Generic Project so that can be correcly converted to VS.NET project
7022 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7024 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7026 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7028 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7029 added return 0 statements after assert() to make compiler happy
7031 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7032 added newline in the def file to keep MSC compiler satisfied
7034 * sdcc/src/z80/gen.c:
7035 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7036 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7037 - solved MSC error in function aopDump()
7039 * sdcc_vc.h: define PREFIX as "\\sdcc"
7041 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7093 Initialized the new field char *Processor field to NULL in all ports
7096 Compiler generated registers for interrupt context saving
7097 were not getting allocated.
7099 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7102 Fixed left shift. Will promote the left side of a left shift
7103 if a) left shifting more than size of operand or b) when assigned
7104 to something size > size of left side
7106 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7216 * sdcc/src/SDCCloop.c:
7217 Previous fix was not good. basic blocks that have "break" or "return" are
7218 not really partof a loop , but live ranges used in these blocks should
7219 be live thru the entire loop, so set partOfLoop but don't add them to
7222 2002-02-21 <johan AT FRIJA>
7224 * src/SDCCcse.c: fixed bug #514308
7226 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8095 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
8097 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
8099 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
