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

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

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

574 bits with offset (case PO_GPR_BIT),
575 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
577 * (isBankInstruction): modified to return 0 for no banking instruction,
578 and 1 for banking instruction,
579 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
580 caused stop processing pCodes after a inline assembly block,
581 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
582 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
583 registers when it shouldn't,
584 * src/pic16/ralloc.c (allocReg): add preliminary support for
585 supporting a limited set of temporary registers,

3592 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3594 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3595 loaded with the linker search paths (-L arguments) and the libraries
3596 to be linked with the current source (-l arguments). Changes
3597 currently will affect only the pic16 port.
3598 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3599 include path the port specific paths and port specific libraries,
3600 * gplink command now contains the $3 argument,
3601 * src/pic16/device.h,
3602 * src/pic16/device.c,: structure PIC_device is made public and
3603 renamed to PIC16_device, the same for variable Pics which is renamed
3604 to Pics16. Updated all references to them.
3605 * src/pic16/glue.c (pic16glue): corrected bug with code
3606 initialization which bypassed the variable initializations block.
3608 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3609 COMPILE_FLAGS and added the --nostdinc option
3611 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3613 * device/include/mc68hc908jb8.h: Register defs for another member

3616 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3618 Documenting changes from previous commits.
3619 * configure.in (version 1.56),
3620 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3621 when generating output files to configure the pic16 library,
3622 but now I've commented it out, since gputils aren't installed in the
3623 SF compile farm, so library won't compile
3625 * device/lib/Makefile.in (version 1.56): initially I've added in
3626 target 'all' the prerequestive 'model-pic16' so it compiled the
3627 pic16 library, but now I've commented it out for the same reasons
3629 * added targets 'model-pic16' and 'objects-pic16' to compile the
3631 * added target 'port-specific-objects-pic16' to handle the
3632 generated libraries and copy them into the build/ directory
3633 * added target 'clean-intermediate-pic16' to clean intermediate
3634 files into pic16 directory
3635 * in target 'installdirs' added line to create directory pic16 in
3636 the installation path
3638 * device/include/Makefile.in (version 1.11): in target 'install'
3639 added lines to copy all header files to installation path,
3640 * in target 'installdirs' added line create directory for pic16
3641 headers in the installation path
3643 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3656 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3657 option so that it actually works. Made it specific to the z80, since
3658 the gbz80 doesn't have these kinds of I/O ports.
3660 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3662 * device/include/z180.h,

3671 portmode; added deprecation warning for bank= and protmode= forms.
3672 Also, guard against buffer overflow.
3673 * src/z80/gen.c (aopGet): generate better code for sfr banked read
3675 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3677 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3678 changed interrupt vector table generation to only emit declared vectors.
3679 * device/include/Makefile.in: added missing backslash
3680 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
3682 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3684 Mainly changes to support compilation of the device libraries
3685 * src/pic16/device.c: stack is allocated via symbol and not
3686 via literal number. The symbol is placed in the corresponding
3687 position of the data ram
3688 * (pic16_dump_section): relocatable and absolute uninitialized
3689 data are now emitted in sorted order to reduce section naming,
3690 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3691 weren't marked as being in the access bank,
3693 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3695 Added portion of GNU PIC Library under the directory
3696 device/include/pic16 and device/lib/pic16. These files
3697 contain the declarations of SFRs for the PIC18Fxx2 devices.
3698 The directory is initialized via configure from toplevel.
3700 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3702 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3703 the spilllocations to be compared correctly
3705 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3707 * src/SDCCast.c (decorateType): fixed bug introduced today
3709 2004-01-12 Borut Razem <borut.razem AT siol.net>
3711 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3714 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3716 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3717 in simpler and even better code
3719 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3721 * src/SDCCicode.c (operandOperation): fixed bug #874819

3725 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3727 * doc/sdccman.lyx: Moved and added some sections, small changes
3728 all over. Telling LaTeX to be less strict with word spacing
3729 to better keep the right margin. Changed some notes about
3730 maintainance of the ports in section 3.2.1 - is it OK like this?
3732 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3734 SDCC source changes:
3735 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3768 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
3769 UPPER for immediate operands,
3770 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3772 * src/pic16/peeph.def: all peepholes with movff are commented out,
3773 because there is a problem in the pcode peep optimizer,
3774 * src/pic16/ralloc.c: the register allocator can now reuse local
3775 function symbols for another function. This saves register usage.
3776 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3778 Added file src/pic16/NOTES with information about program writing on
3779 the current port version.

3788 * src/SDCCmain.c : fixed #872250: -l command line defined library
3789 files are scanned before standard library files
3791 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3808 gen51Code): more efficient parameter receive for --model-large
3811 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3814 * src/z80/main.c: added missed needLinkerScript flags (more than
3815 one port structure defined in these file)
3816 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
3819 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

3832 needLinkerScript flag
3834 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3835 * src/pic/glue.c: added variable udata_section_name to
3836 override default uninitialized data segment definition for
3837 devices only with SHAREBANK memory (reported from Erik Epetrich)
3838 * (pic14emitOverlay): modified to emit a commented overlay segment
3839 directive when no overlay data exist
3840 * (picglue): modified to emit uninitialized data segment
3841 according to udata_section_name

3846 arguments via -W option
3847 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3848 object file from '.rel' to '.o' in port->linker structure,
3849 changed size of fptr from 2 to 3 in port structure
3851 2004-01-07 Borut Razem <borut.razem AT siol.net>
3853 * support/scripts/sdcc.nsi: update PATH
3854 * support/scripts/sdcc.ico: craeted
3856 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3859 * doc/Makefile: fix install
3861 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3863 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3865 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3866 how the function variable allocation summary is displayed; also
3867 include information about variables allocated to the overlay
3870 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3872 * as/mcs51/lkmain.c: Help about -Y option

3884 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3886 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3887 (default behaviour).
3889 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3891 A python script to validate compiler diagnostic messages. It can be
3892 used to verify that sdcc complains about bad c source code and
3893 gives a good location of the error.
3894 * support/valdiag/Makefile,
3895 * support/valdiag/valdiag.py,
3896 * support/valdiag/tests/*
3898 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3900 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3901 * src/SDCCsymt.c (newEnumType),

3909 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3911 * src/common.h: added ifndef/define/endif macros
3912 around the header file.
3913 Bug reported from Jesus Calvino-Fraga
3915 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3917 * sdcc.spec: updated
3918 * device/include/Makefile.in: don't install CVS directories
3919 * device/lib/Makefile.in: added removal of CVS directories after install
3920 * doc/Makefile: fixed install, added local_icons
3921 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3922 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3923 * src/ds390/gen.c (genRightShift): fixed bug #870788
3924 * src/SDCCast.c (decorateType): fixed bug #870781
3926 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3928 PIC16 port related changes:
3929 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3930 added variable stackPos,
3932 * gen.c: genCall, assignResultValue: added support for
3933 pushing/retrieving function parameters to/from stack,
3934 genFunction,genEndFunction: setup stack frame for the
3936 genAddrOf: will be changed according to bug 863624
3938 * added files genutils.c and genutils.h which contain gen*
3939 debugged and optimised functions extracted from gen.c
3941 * glue.c: added variable 'externs' which holds extern symbols,
3942 pic16emitRegularMap: is modified to properly handle relocatable
3943 symbols under the new scheme,
3944 pic16createInterruptVect: is modified
3945 pic16printPublics: is modified to emit 'global' assembler directives,
3946 added pic16_printExterns to print extern symbols,
3947 pic16glue: initializes stack/frame pointer in the beginning of
3948 the assembly output. Temporary hack, will be corrected later,
3949 because gplink yet does not support stack and SDCC does not
3950 yet support a type of crt0.o object to create the final binary.
3952 * Removed many lines that contain 8051 legacy code.
3953 * The code is finally placed under a 'code' directive.
3954 * Added port specific options.
3956 * _process_pragma: simplified since now we do not need *special*
3957 include file to define SFR registers. But a separate header
3958 will be needed. This will be developed later.
3959 * _pic16_parseOptions: added, parses port specific options:
3960 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3961 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3962 --preplace-udata-with=
3964 * _pic16_setDefaultOptions: modified to initialize section names,
3965 but hack is temporarly out of order since it needs improvement.
3966 * _pic16_genAssemblerPreamble: configuration words are emitted by
3967 their address instead of their name. This part is incomplete and
3968 supports only the 18Fxx2 devices. Other devices will emit an error
3969 during assembly since they do not contain the same set of config
3971 * _pic16_genIVT: is modified,
3973 * pcode.c: added definitions for some hardware registers that are needed
3975 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3976 All PCI entries are updated. Now LFSR is supported.
3977 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3978 * added pic16_newpCodeOpLit2 to support instructions with
3979 two literal arguments
3980 * pic16_pCode2str: corrected code that emits assembler instructions
3981 with two literal operands and those that have an access bit modifier
3982 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3983 this fixes a bug which caused some labels to be lost, when an
3984 assembler directive was added, i.e. banksel,
3985 * pic16_FixRegisterBanking: improved logic that causes the insertion
3987 * InlineFunction: functions that are called once, are not any more
3988 inlined. This can be a port option in the future,
3990 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3992 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3993 hold the corresponding uninitialized symbols,
3994 * pic16_allocProcessorRegister: registers have explicit marked the
3996 * pic16_allocInternalRegister: registers are explicit marked as
3998 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3999 processing list, so bit registers were lost,
4002 * ralloc.h: added field 'accessBank' and original symbol operand
4003 in register definition,
4004 * removed the field isMapped from register definition,
4006 ** Several functions have been removed from various sources:
4007 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4008 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4009 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4010 pic16_assignRelocatableRegisters
4012 ** others have been introduced:
4013 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4014 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4016 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4018 * support/scripts/inc2h.pl: changed definition of BIT_AT
4019 to emit 'sbit at' instead of 'bit at'. This was a request.
4021 PIC16 port related preliminary changes:
4022 * gen.c: prefixed function popRegFromString with
4023 pic16_ and all references to it corrected
4024 * pcode.c: all pic16_pc_* hardware registers prefixed
4025 with underscore (_),
4026 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4027 * ralloc.c: newReg(): when register is REG_SFR then
4028 set address to rIdx,
4029 pic16_allocProcessorRegister(): marks register wasUsed=0
4030 pic16_writeUsedRegs(): added a call to assign processor
4031 registers via pic16_assignFixedRegisters
4033 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4035 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4036 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4037 variables in unused register banks. Also the SSEG is placed
4038 wherever there is enough space for it, and IDATA can be anywhere
4039 in internal RAM. For now compile using -Wl-Y[stack_size].
4040 The mem file is different for this option as well, since it
4041 makes no sense of talking about DSEG lenght.
4043 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4045 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4046 in certain cases, e.g. when ROM assignment, patch provided
4047 from Albert den Haan.
4049 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5057 If they pop r0/r1 they must be called in the opposite order than aopOp().
5058 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5059 (resp. --stack-auto), prepared for --xstack

5068 these ports have their own __sdcc_external_start()
5070 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5072 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5073 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5074 type for bits was changed. It resulted in bit variables becoming
5075 global, which is not permitted in PIC 14 assembly output.
5077 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5079 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5081 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5083 Z80 and MCS51 linkers complaint if a public symbol is defined

5092 A few small changes that speed up the peephole optimizer.
5096 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5098 Try to make the peephole optimizer smarter by maintaining
5099 an association between the assembly source code and the
5100 iCodes that originated them. Put this information to use
5101 with a new peephole rule condition "notVolatile" so that
5102 the rules can be aggressive yet still safe.
5107 * src/mcs51/peeph.def
5109 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5113 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5114 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5115 if the left or right operand symbols have the accuse flag set.
5117 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5119 Changed the type of the result of the ! (NOT) operator to char;
5120 previously it returned the same type as the source. This allows
5121 us to eliminate all the genFloatNot functions (all of its target
5122 implementations were very buggy) since !float can use the same
5125 * src/SDCCicode.c (ast2iCode): ! returns char

5134 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5135 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5136 during interrupts. Ensure WSAVE is located at a shared bank address.
5137 2. Fixed page selection in some places
5138 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5139 the registers name strings.
5140 4. Fixed "signed / unsigned compare" compiler warnings.
5141 5. The PIC port manages its own allocation of the general purpose
5142 registers, but makes no attempt to reuse them. As a result when
5143 compiling it soon runs out of general purpose registers. Some
5144 additional code was added to the files pcode.c and device.c to walk
5145 through the function call tree and rename the registers so that they
5155 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5162 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5164 Made bitfield a distinct type from bit so that bitfields
5165 convert as per ANSI C and bits retain their traditional
5166 boolean style behaviour. Implemented bitfield support in
5174 * src/ds390/gen.c: bit v bitfield split
5175 * src/z80/gen.c: New support for bitfields
5176 * support/regression/tests/bitfields.c: reenabled z80,
5179 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5181 Rules 246.x, 247.x relate to bitfields, the others speed up
5182 access to xdata mapped I/O devices.
5184 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5186 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5188 Cleaned up genPackBits and genUnpackBits and added two helper
5189 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5190 for literal assignments in genPackBits (thanks to Frieder for
5196 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5198 Fixed bug #748310 (pointer to function type mishandled when the
5199 function name is omitted). Also fixed a SIGSEGV when a function
5200 attribute (reentrant, etc) is used on a non-function or on a
5201 function but misplaced before the parameter list.
5203 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5205 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5228 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5230 Made the constant following the "interrupt" keyword optional. If
5231 omitted, the function will not automatically be given an entry
5232 in the interrupt vector table (similar to #pragma NOIV, but
5233 less syntacticly kludgy). The interrupt number is also now
5234 range checked. Also fixed a bug in the high order bit example

5248 * src/SDCCicode.c (operandOperation): rewritten some ops
5249 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5250 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5252 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5253 be re-activated by defining REDUCE_LITERALS)
5254 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5255 unsigned, but are signed by default
5256 * src/SDCCval.c (constVal): rearranged
5257 * src/SDCCval.c (valMod): preliminary fix
5258 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5710 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5711 the regression tests I'm not brave enough to enable 245.b, 245.c
5712 * doc/sdccman.lyx: added latex preamble for hyperref package.
5713 Using pdflatex this will give you a hyperlinked pdf file with
5714 bookmarks. (prepend '%' before /usepackage if this breaks something)

5755 it can be defined with CFLAGS when running configure
5756 * src/SDCCmain.c: fixed compiling + linking with object files
5758 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5761 added --disable-pic16-port
5762 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5763 * src/SDCCmain.c: linkOptions is changed to set *,
5764 added if/endif conditional macros to remove options help
5765 messages from optionsTable when a port is not configured, added
5766 support for the PIc16 port in the ports table, when executing
5767 the compiler with no port specified on command line, a default
5768 port is selected with the new macro DEFAULT_PORT which is
5769 defined in port.h, in setDefaultOptions() linkOptions is removed
5770 from initialization assignment, since now it is a set,
5771 parseCmdLine uses setParseWithComma for linkOptions, in
5772 linkEdit() linkOptions are accessed with new function indexSet()
5773 which returns the i'th item of a set variable. See SDCCset.c, in
5774 linkEdit() when calling buildCmdLine(), added linkOptions as
5775 last argument. Now users can pass arguments to gplink via the
5776 -Wl option, main() uses pic16glue() to glue up pic16 programs
5777 * src/SDCCpeeph.c: various changes to support pic16

5788 * src/pic16/glue.c: commented out some error producing lines
5789 * src/pic16/main.c: __config directives are commented out to stop
5790 gpasm complaining and test the linkage with gplink, _linkCmd and
5791 _asmCmd changed to be more gplink and gpasm friendly
5792 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5793 produced an error when parsed, peep rule 12 is added to utilize
5794 movff, but it is commented out since the pCode does not support
5795 yet a command with 2 address arguments
5797 2003-05-18 <johan AT balder>
5799 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5800 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5824 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5826 2003-05-11 Borut Razem <borut.razem AT siol.net>
5828 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5829 the path of bin directory, so that PATH is the only env. variable, which has to be set
5830 in case of standard installation.
5831 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6860 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6862 * in \sdcc\as\mcs51\ changed these files in order to create an
6863 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6864 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6865 following files to include the previous two files: aslink.dsp,
6866 Makefile.aslink, Makefile.bcc, and Makefile.in.
6868 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6869 .adb instead of .cdb
6871 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6873 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6874 value from option --iram-size.
6876 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6878 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6881 2002-09-18 <wiml AT hhhh.org>
6883 * SDCClrange.h: exposed setFromRange() and setToRange()
6884 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6885 packRegsForAccUse() (bug 542397)
6886 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6887 multiple times and emitting the fetch operations more than once
6888 added aopGetUsesAcc() function to allow binary operators to
6889 fetch their operands in the correct order; made genMinus() emit
6890 compact code for X = LITERAL - Y
6892 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6893 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6894 sprintf() in line 1267.
6896 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6897 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6900 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6901 Changes to aslink (All the changes are marked with 'JCF'):
6903 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6906 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6907 area BSEG. Also moves, if possible, the DATA area down into the internal
6908 ram so more space is available.
6910 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6913 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6914 not bytes. Function summary() which creates a memory usage summary
6915 file with extension .mem. Reports of overlaping stack and small stack
6916 size. If the space for the stack is less than 16 bytes aslink trows a
6919 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6920 the 8051. Option 'y' for memory summary output file.
6922 Changes to sdcc (All the changes are marked with 'JCF'):
6924 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6926 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6927 overlaying area for it (uses RegBankUsed[4]).
6929 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6930 bank zero as used by default. By default aslink locates the stack
6931 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6932 the creation of the .mem file. Delegates the allocation of data area
6933 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6934 the begining of the stack area to aslink.
6936 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6937 glue() in SDCCglue.c creates an area for it.
6939 2002-09-03 Borut Razem <borut.razem AT siol.net>
6940 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6941 sdcc/src/pic/glue.c:
6942 introduced atexit() handler for teporay files removal in case of
6943 errors, assertions, ...
6945 2002-08-29 Borut Razem <borut.razem AT siol.net>
6946 * sdcc/support/cpp2/auto-host_vc_in.h:
6947 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6948 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6949 Maybe there is a similar problem with BORLANDC? It should be checked!
6951 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6952 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6953 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6954 was not executed, and the compiler (cl) launched a warning:
6955 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6957 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6958 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

6969 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6970 - added Release configuration in VS projects
6971 - review of compiler an linker options
6972 - VC .exe files are generated in bin_vc directory, not to interfere
6973 with binaries generated from other projects (cygwin, mingw, bcc ...)
6975 * sdcc/src/yacc.dsp: added
6977 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6978 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6979 and insert the version number definitions from .version
6981 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6983 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6989 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6990 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6992 2002-08-11 Borut Razem <borut.razem AT siol.net>
6993 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6995 2002-08-10 Borut Razem <borut.razem AT siol.net>
6996 * src/SDCCmain.c (main):
6997 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6998 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6999 The consequence was that some temporary files were not removed.
7002 unification of code in functions tempfilename() and tempfile():
7003 function tempnam() is defined in Visual Studio 6.0 and .NET
7005 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7007 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7008 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7009 - removed compiler command line option /WX: Treats all warnings as errors
7010 - update a list of source files, included into the project
7012 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7013 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7014 changed project type to Generic Project so that can be correcly converted to VS.NET project
7016 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7018 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7023 added return 0 statements after assert() to make compiler happy
7025 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7026 added newline in the def file to keep MSC compiler satisfied
7028 * sdcc/src/z80/gen.c:
7029 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7030 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7031 - solved MSC error in function aopDump()
7033 * sdcc_vc.h: define PREFIX as "\\sdcc"
7035 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7091 were not getting allocated.
7093 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7096 Fixed left shift. Will promote the left side of a left shift
7097 if a) left shifting more than size of operand or b) when assigned
7098 to something size > size of left side
7100 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7210 * sdcc/src/SDCCloop.c:
7211 Previous fix was not good. basic blocks that have "break" or "return" are
7212 not really partof a loop , but live ranges used in these blocks should
7213 be live thru the entire loop, so set partOfLoop but don't add them to
7216 2002-02-21 <johan AT FRIJA>

8089 * 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.
8091 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
8093 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
8095 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
8097 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
