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

537 to call when a stack overflow occurs,
538 * (malloc.h): added CVS Id tag,
539 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
541 * added libc directory. The current version of LibC contains string
542 functions, ctype functions and macros and some functions of the
543 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
544 be extensively tested in the future. Standard disclaimer here.
545 Library is not automatically build yet. But one can build it by
546 invoking 'make' inside the libc directory.
547 * added ADC library under libio. Preliminary version yet.
549 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

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

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

585 genDataPointerSet): ensure assignments always copy in MSB to LSB
587 (loadRegFromAop): recognize CLRH optimization,
588 (genFunction): optimize RECEIVE iCodes in reentrant functions
590 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3580 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
3582 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
3584 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
3587 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3589 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3590 loaded with the linker search paths (-L arguments) and the libraries
3591 to be linked with the current source (-l arguments). Changes
3592 currently will affect only the pic16 port.
3593 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3594 include path the port specific paths and port specific libraries,
3595 * gplink command now contains the $3 argument,
3596 * src/pic16/device.h,
3597 * src/pic16/device.c,: structure PIC_device is made public and
3598 renamed to PIC16_device, the same for variable Pics which is renamed
3599 to Pics16. Updated all references to them.
3600 * src/pic16/glue.c (pic16glue): corrected bug with code
3601 initialization which bypassed the variable initializations block.
3603 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3604 COMPILE_FLAGS and added the --nostdinc option
3606 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3608 * device/include/mc68hc908jb8.h: Register defs for another member
3609 of the hc08 family. Contributed by Bjorn Bringert - thanks!
3611 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3613 Documenting changes from previous commits.
3614 * configure.in (version 1.56),
3615 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3616 when generating output files to configure the pic16 library,
3617 but now I've commented it out, since gputils aren't installed in the
3618 SF compile farm, so library won't compile
3620 * device/lib/Makefile.in (version 1.56): initially I've added in
3621 target 'all' the prerequestive 'model-pic16' so it compiled the
3622 pic16 library, but now I've commented it out for the same reasons
3624 * added targets 'model-pic16' and 'objects-pic16' to compile the
3626 * added target 'port-specific-objects-pic16' to handle the
3627 generated libraries and copy them into the build/ directory
3628 * added target 'clean-intermediate-pic16' to clean intermediate
3629 files into pic16 directory
3630 * in target 'installdirs' added line to create directory pic16 in
3631 the installation path
3633 * device/include/Makefile.in (version 1.11): in target 'install'
3634 added lines to copy all header files to installation path,
3635 * in target 'installdirs' added line create directory for pic16
3636 headers in the installation path
3638 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

3651 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3652 option so that it actually works. Made it specific to the z80, since
3653 the gbz80 doesn't have these kinds of I/O ports.
3655 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3657 * device/include/z180.h,

3670 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3672 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3673 changed interrupt vector table generation to only emit declared vectors.
3674 * device/include/Makefile.in: added missing backslash
3675 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
3677 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3679 Mainly changes to support compilation of the device libraries
3680 * src/pic16/device.c: stack is allocated via symbol and not
3681 via literal number. The symbol is placed in the corresponding
3682 position of the data ram
3683 * (pic16_dump_section): relocatable and absolute uninitialized
3684 data are now emitted in sorted order to reduce section naming,
3685 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3686 weren't marked as being in the access bank,
3688 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3690 Added portion of GNU PIC Library under the directory
3691 device/include/pic16 and device/lib/pic16. These files
3692 contain the declarations of SFRs for the PIC18Fxx2 devices.
3693 The directory is initialized via configure from toplevel.
3695 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3697 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3698 the spilllocations to be compared correctly
3700 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3702 * src/SDCCast.c (decorateType): fixed bug introduced today
3704 2004-01-12 Borut Razem <borut.razem AT siol.net>
3706 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3709 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3711 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3712 in simpler and even better code
3714 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3716 * src/SDCCicode.c (operandOperation): fixed bug #874819

3720 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3722 * doc/sdccman.lyx: Moved and added some sections, small changes
3723 all over. Telling LaTeX to be less strict with word spacing
3724 to better keep the right margin. Changed some notes about
3725 maintainance of the ports in section 3.2.1 - is it OK like this?
3727 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3764 UPPER for immediate operands,
3765 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3767 * src/pic16/peeph.def: all peepholes with movff are commented out,
3768 because there is a problem in the pcode peep optimizer,
3769 * src/pic16/ralloc.c: the register allocator can now reuse local

3771 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3773 Added file src/pic16/NOTES with information about program writing on
3774 the current port version.

3783 * src/SDCCmain.c : fixed #872250: -l command line defined library
3784 files are scanned before standard library files
3786 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3803 gen51Code): more efficient parameter receive for --model-large
3806 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3809 * src/z80/main.c: added missed needLinkerScript flags (more than
3810 one port structure defined in these file)
3811 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3827 needLinkerScript flag
3829 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3830 * src/pic/glue.c: added variable udata_section_name to
3831 override default uninitialized data segment definition for
3832 devices only with SHAREBANK memory (reported from Erik Epetrich)
3833 * (pic14emitOverlay): modified to emit a commented overlay segment
3834 directive when no overlay data exist
3835 * (picglue): modified to emit uninitialized data segment
3836 according to udata_section_name

3842 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3843 object file from '.rel' to '.o' in port->linker structure,
3844 changed size of fptr from 2 to 3 in port structure
3846 2004-01-07 Borut Razem <borut.razem AT siol.net>
3848 * support/scripts/sdcc.nsi: update PATH
3849 * support/scripts/sdcc.ico: craeted
3851 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
3853 * device/include/Makefile.in: fix install
3854 * doc/Makefile: fix install
3856 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3858 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3860 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

3862 include information about variables allocated to the overlay
3865 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3867 * as/mcs51/lkmain.c: Help about -Y option

3879 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3881 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3882 (default behaviour).
3884 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3886 A python script to validate compiler diagnostic messages. It can be
3887 used to verify that sdcc complains about bad c source code and
3888 gives a good location of the error.
3889 * support/valdiag/Makefile,
3890 * support/valdiag/valdiag.py,
3891 * support/valdiag/tests/*
3893 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3895 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3896 * src/SDCCsymt.c (newEnumType),

3904 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3906 * src/common.h: added ifndef/define/endif macros
3907 around the header file.
3908 Bug reported from Jesus Calvino-Fraga
3910 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3912 * sdcc.spec: updated
3913 * device/include/Makefile.in: don't install CVS directories
3914 * device/lib/Makefile.in: added removal of CVS directories after install
3915 * doc/Makefile: fixed install, added local_icons
3916 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3917 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3918 * src/ds390/gen.c (genRightShift): fixed bug #870788
3919 * src/SDCCast.c (decorateType): fixed bug #870781
3921 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3923 PIC16 port related changes:
3924 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3925 added variable stackPos,
3927 * gen.c: genCall, assignResultValue: added support for
3928 pushing/retrieving function parameters to/from stack,
3929 genFunction,genEndFunction: setup stack frame for the
3931 genAddrOf: will be changed according to bug 863624
3933 * added files genutils.c and genutils.h which contain gen*
3934 debugged and optimised functions extracted from gen.c
3936 * glue.c: added variable 'externs' which holds extern symbols,
3937 pic16emitRegularMap: is modified to properly handle relocatable
3938 symbols under the new scheme,
3939 pic16createInterruptVect: is modified
3940 pic16printPublics: is modified to emit 'global' assembler directives,
3941 added pic16_printExterns to print extern symbols,
3942 pic16glue: initializes stack/frame pointer in the beginning of
3943 the assembly output. Temporary hack, will be corrected later,
3944 because gplink yet does not support stack and SDCC does not
3945 yet support a type of crt0.o object to create the final binary.
3947 * Removed many lines that contain 8051 legacy code.
3948 * The code is finally placed under a 'code' directive.
3949 * Added port specific options.
3951 * _process_pragma: simplified since now we do not need *special*
3952 include file to define SFR registers. But a separate header
3953 will be needed. This will be developed later.
3954 * _pic16_parseOptions: added, parses port specific options:
3955 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3956 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3957 --preplace-udata-with=
3959 * _pic16_setDefaultOptions: modified to initialize section names,
3960 but hack is temporarly out of order since it needs improvement.
3961 * _pic16_genAssemblerPreamble: configuration words are emitted by
3962 their address instead of their name. This part is incomplete and
3963 supports only the 18Fxx2 devices. Other devices will emit an error
3964 during assembly since they do not contain the same set of config
3966 * _pic16_genIVT: is modified,
3968 * pcode.c: added definitions for some hardware registers that are needed
3970 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3971 All PCI entries are updated. Now LFSR is supported.
3972 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3973 * added pic16_newpCodeOpLit2 to support instructions with
3974 two literal arguments
3975 * pic16_pCode2str: corrected code that emits assembler instructions
3976 with two literal operands and those that have an access bit modifier
3977 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3978 this fixes a bug which caused some labels to be lost, when an
3979 assembler directive was added, i.e. banksel,
3980 * pic16_FixRegisterBanking: improved logic that causes the insertion
3982 * InlineFunction: functions that are called once, are not any more
3983 inlined. This can be a port option in the future,
3985 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3987 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3988 hold the corresponding uninitialized symbols,
3989 * pic16_allocProcessorRegister: registers have explicit marked the
3991 * pic16_allocInternalRegister: registers are explicit marked as
3993 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3994 processing list, so bit registers were lost,
3997 * ralloc.h: added field 'accessBank' and original symbol operand
3998 in register definition,
3999 * removed the field isMapped from register definition,
4001 ** Several functions have been removed from various sources:
4002 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4003 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4004 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4005 pic16_assignRelocatableRegisters
4007 ** others have been introduced:
4008 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4009 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4011 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4013 * support/scripts/inc2h.pl: changed definition of BIT_AT
4014 to emit 'sbit at' instead of 'bit at'. This was a request.
4016 PIC16 port related preliminary changes:
4017 * gen.c: prefixed function popRegFromString with
4018 pic16_ and all references to it corrected
4019 * pcode.c: all pic16_pc_* hardware registers prefixed
4020 with underscore (_),
4021 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4022 * ralloc.c: newReg(): when register is REG_SFR then
4023 set address to rIdx,
4024 pic16_allocProcessorRegister(): marks register wasUsed=0
4025 pic16_writeUsedRegs(): added a call to assign processor
4026 registers via pic16_assignFixedRegisters
4028 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4030 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4031 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4032 variables in unused register banks. Also the SSEG is placed
4033 wherever there is enough space for it, and IDATA can be anywhere
4034 in internal RAM. For now compile using -Wl-Y[stack_size].
4035 The mem file is different for this option as well, since it
4036 makes no sense of talking about DSEG lenght.
4038 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4040 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4041 in certain cases, e.g. when ROM assignment, patch provided
4042 from Albert den Haan.
4044 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5063 these ports have their own __sdcc_external_start()
5065 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5067 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5068 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5069 type for bits was changed. It resulted in bit variables becoming
5070 global, which is not permitted in PIC 14 assembly output.
5072 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5074 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5087 A few small changes that speed up the peephole optimizer.
5091 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5093 Try to make the peephole optimizer smarter by maintaining
5094 an association between the assembly source code and the
5095 iCodes that originated them. Put this information to use
5096 with a new peephole rule condition "notVolatile" so that
5097 the rules can be aggressive yet still safe.
5102 * src/mcs51/peeph.def
5104 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5108 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5109 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5110 if the left or right operand symbols have the accuse flag set.
5112 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5114 Changed the type of the result of the ! (NOT) operator to char;
5115 previously it returned the same type as the source. This allows
5116 us to eliminate all the genFloatNot functions (all of its target
5117 implementations were very buggy) since !float can use the same
5120 * src/SDCCicode.c (ast2iCode): ! returns char

5129 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5130 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5131 during interrupts. Ensure WSAVE is located at a shared bank address.
5132 2. Fixed page selection in some places
5133 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5134 the registers name strings.
5135 4. Fixed "signed / unsigned compare" compiler warnings.
5136 5. The PIC port manages its own allocation of the general purpose
5137 registers, but makes no attempt to reuse them. As a result when
5138 compiling it soon runs out of general purpose registers. Some
5139 additional code was added to the files pcode.c and device.c to walk
5140 through the function call tree and rename the registers so that they
5150 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5157 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5159 Made bitfield a distinct type from bit so that bitfields
5160 convert as per ANSI C and bits retain their traditional
5161 boolean style behaviour. Implemented bitfield support in
5169 * src/ds390/gen.c: bit v bitfield split
5170 * src/z80/gen.c: New support for bitfields
5171 * support/regression/tests/bitfields.c: reenabled z80,
5174 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5176 Rules 246.x, 247.x relate to bitfields, the others speed up
5177 access to xdata mapped I/O devices.
5179 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5181 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5183 Cleaned up genPackBits and genUnpackBits and added two helper
5184 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5185 for literal assignments in genPackBits (thanks to Frieder for
5191 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5193 Fixed bug #748310 (pointer to function type mishandled when the
5194 function name is omitted). Also fixed a SIGSEGV when a function
5195 attribute (reentrant, etc) is used on a non-function or on a
5196 function but misplaced before the parameter list.
5198 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5200 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5223 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5225 Made the constant following the "interrupt" keyword optional. If
5226 omitted, the function will not automatically be given an entry
5227 in the interrupt vector table (similar to #pragma NOIV, but
5228 less syntacticly kludgy). The interrupt number is also now
5229 range checked. Also fixed a bug in the high order bit example

5250 unsigned, but are signed by default
5251 * src/SDCCval.c (constVal): rearranged
5252 * src/SDCCval.c (valMod): preliminary fix
5253 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5676 for a non-native english speaker.
5677 Please feel free to add to the manual or to correct my changes.

5705 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5706 the regression tests I'm not brave enough to enable 245.b, 245.c
5707 * doc/sdccman.lyx: added latex preamble for hyperref package.
5708 Using pdflatex this will give you a hyperlinked pdf file with
5709 bookmarks. (prepend '%' before /usepackage if this breaks something)

5747 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5749 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5750 it can be defined with CFLAGS when running configure
5751 * src/SDCCmain.c: fixed compiling + linking with object files
5753 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5756 added --disable-pic16-port
5757 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5758 * src/SDCCmain.c: linkOptions is changed to set *,
5759 added if/endif conditional macros to remove options help
5760 messages from optionsTable when a port is not configured, added
5761 support for the PIc16 port in the ports table, when executing
5762 the compiler with no port specified on command line, a default
5763 port is selected with the new macro DEFAULT_PORT which is
5764 defined in port.h, in setDefaultOptions() linkOptions is removed
5765 from initialization assignment, since now it is a set,
5766 parseCmdLine uses setParseWithComma for linkOptions, in
5767 linkEdit() linkOptions are accessed with new function indexSet()
5768 which returns the i'th item of a set variable. See SDCCset.c, in
5769 linkEdit() when calling buildCmdLine(), added linkOptions as
5770 last argument. Now users can pass arguments to gplink via the
5771 -Wl option, main() uses pic16glue() to glue up pic16 programs

5783 * src/pic16/glue.c: commented out some error producing lines
5784 * src/pic16/main.c: __config directives are commented out to stop
5785 gpasm complaining and test the linkage with gplink, _linkCmd and
5786 _asmCmd changed to be more gplink and gpasm friendly
5787 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5788 produced an error when parsed, peep rule 12 is added to utilize
5789 movff, but it is commented out since the pCode does not support
5790 yet a command with 2 address arguments
5792 2003-05-18 <johan AT balder>
5794 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5795 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5819 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5821 2003-05-11 Borut Razem <borut.razem AT siol.net>
5823 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5824 the path of bin directory, so that PATH is the only env. variable, which has to be set
5825 in case of standard installation.
5826 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6855 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6857 * in \sdcc\as\mcs51\ changed these files in order to create an
6858 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6859 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6860 following files to include the previous two files: aslink.dsp,
6861 Makefile.aslink, Makefile.bcc, and Makefile.in.
6863 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6864 .adb instead of .cdb
6866 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6868 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6869 value from option --iram-size.
6871 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6873 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6876 2002-09-18 <wiml AT hhhh.org>
6878 * SDCClrange.h: exposed setFromRange() and setToRange()
6879 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6880 packRegsForAccUse() (bug 542397)
6881 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6882 multiple times and emitting the fetch operations more than once
6883 added aopGetUsesAcc() function to allow binary operators to
6884 fetch their operands in the correct order; made genMinus() emit
6885 compact code for X = LITERAL - Y
6887 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6888 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6889 sprintf() in line 1267.
6891 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6892 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6895 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6896 Changes to aslink (All the changes are marked with 'JCF'):
6898 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6901 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6902 area BSEG. Also moves, if possible, the DATA area down into the internal
6903 ram so more space is available.
6905 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6908 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6909 not bytes. Function summary() which creates a memory usage summary
6910 file with extension .mem. Reports of overlaping stack and small stack
6911 size. If the space for the stack is less than 16 bytes aslink trows a
6914 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6915 the 8051. Option 'y' for memory summary output file.
6917 Changes to sdcc (All the changes are marked with 'JCF'):
6919 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6921 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6922 overlaying area for it (uses RegBankUsed[4]).
6924 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6925 bank zero as used by default. By default aslink locates the stack
6926 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6927 the creation of the .mem file. Delegates the allocation of data area
6928 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6929 the begining of the stack area to aslink.
6931 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6932 glue() in SDCCglue.c creates an area for it.
6934 2002-09-03 Borut Razem <borut.razem AT siol.net>
6935 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6936 sdcc/src/pic/glue.c:
6937 introduced atexit() handler for teporay files removal in case of
6938 errors, assertions, ...
6940 2002-08-29 Borut Razem <borut.razem AT siol.net>
6941 * sdcc/support/cpp2/auto-host_vc_in.h:
6942 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6943 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6944 Maybe there is a similar problem with BORLANDC? It should be checked!
6946 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6947 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6948 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6949 was not executed, and the compiler (cl) launched a warning:
6950 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6952 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6965 - added Release configuration in VS projects
6966 - review of compiler an linker options
6967 - VC .exe files are generated in bin_vc directory, not to interfere
6968 with binaries generated from other projects (cygwin, mingw, bcc ...)
6970 * sdcc/src/yacc.dsp: added
6972 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6973 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6974 and insert the version number definitions from .version

6988 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6990 2002-08-10 Borut Razem <borut.razem AT siol.net>
6991 * src/SDCCmain.c (main):
6992 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6993 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6994 The consequence was that some temporary files were not removed.
6997 unification of code in functions tempfilename() and tempfile():
6998 function tempnam() is defined in Visual Studio 6.0 and .NET
7000 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7002 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7003 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7004 - removed compiler command line option /WX: Treats all warnings as errors
7005 - update a list of source files, included into the project
7007 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

7018 added return 0 statements after assert() to make compiler happy
7020 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7021 added newline in the def file to keep MSC compiler satisfied
7023 * sdcc/src/z80/gen.c:
7024 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7025 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7026 - solved MSC error in function aopDump()
7028 * sdcc_vc.h: define PREFIX as "\\sdcc"
7030 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7205 * sdcc/src/SDCCloop.c:
7206 Previous fix was not good. basic blocks that have "break" or "return" are
7207 not really partof a loop , but live ranges used in these blocks should
7208 be live thru the entire loop, so set partOfLoop but don't add them to
7211 2002-02-21 <johan AT FRIJA>

8055 2001-09-02 Michael Hope <michaelh AT juju.net.nz>
8057 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
8059 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
8061 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
8063 * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs. Had to shift some functions about to do it.
8065 2001-09-01 Michael Hope <michaelh AT juju.net.nz>
8067 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
8068 (genCmp): Fixed up genCmp for the GB with longs.
8070 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
8072 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
8074 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
8076 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

8080 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
8082 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
8084 * 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.
8086 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
8088 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
8090 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
8092 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
