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

552 to call when a stack overflow occurs,
553 * (malloc.h): added CVS Id tag,
554 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
556 * added libc directory. The current version of LibC contains string
557 functions, ctype functions and macros and some functions of the
558 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
559 be extensively tested in the future. Standard disclaimer here.
560 Library is not automatically build yet. But one can build it by
561 invoking 'make' inside the libc directory.
562 * added ADC library under libio. Preliminary version yet.

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

587 * (isBankInstruction): modified to return 0 for no banking instruction,
588 and 1 for banking instruction,
589 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
590 caused stop processing pCodes after a inline assembly block,
591 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3602 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3604 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3605 loaded with the linker search paths (-L arguments) and the libraries
3606 to be linked with the current source (-l arguments). Changes
3607 currently will affect only the pic16 port.
3608 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3609 include path the port specific paths and port specific libraries,
3610 * gplink command now contains the $3 argument,
3611 * src/pic16/device.h,
3612 * src/pic16/device.c,: structure PIC_device is made public and
3613 renamed to PIC16_device, the same for variable Pics which is renamed
3614 to Pics16. Updated all references to them.
3615 * src/pic16/glue.c (pic16glue): corrected bug with code
3616 initialization which bypassed the variable initializations block.

3626 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3628 Documenting changes from previous commits.
3629 * configure.in (version 1.56),
3630 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3631 when generating output files to configure the pic16 library,
3632 but now I've commented it out, since gputils aren't installed in the
3633 SF compile farm, so library won't compile
3635 * device/lib/Makefile.in (version 1.56): initially I've added in
3636 target 'all' the prerequestive 'model-pic16' so it compiled the
3637 pic16 library, but now I've commented it out for the same reasons
3639 * added targets 'model-pic16' and 'objects-pic16' to compile the
3641 * added target 'port-specific-objects-pic16' to handle the
3642 generated libraries and copy them into the build/ directory
3643 * added target 'clean-intermediate-pic16' to clean intermediate
3644 files into pic16 directory
3645 * in target 'installdirs' added line to create directory pic16 in
3646 the installation path
3648 * device/include/Makefile.in (version 1.11): in target 'install'
3649 added lines to copy all header files to installation path,
3650 * in target 'installdirs' added line create directory for pic16
3651 headers in the installation path

3666 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3667 option so that it actually works. Made it specific to the z80, since
3668 the gbz80 doesn't have these kinds of I/O ports.
3670 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3672 * device/include/z180.h,

3685 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3687 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3688 changed interrupt vector table generation to only emit declared vectors.
3689 * device/include/Makefile.in: added missing backslash
3690 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

3694 Mainly changes to support compilation of the device libraries
3695 * src/pic16/device.c: stack is allocated via symbol and not
3696 via literal number. The symbol is placed in the corresponding
3697 position of the data ram
3698 * (pic16_dump_section): relocatable and absolute uninitialized
3699 data are now emitted in sorted order to reduce section naming,
3700 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3701 weren't marked as being in the access bank,
3703 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3705 Added portion of GNU PIC Library under the directory
3706 device/include/pic16 and device/lib/pic16. These files
3707 contain the declarations of SFRs for the PIC18Fxx2 devices.
3708 The directory is initialized via configure from toplevel.
3710 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3712 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3713 the spilllocations to be compared correctly
3715 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3717 * src/SDCCast.c (decorateType): fixed bug introduced today
3719 2004-01-12 Borut Razem <borut.razem AT siol.net>
3721 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3737 * doc/sdccman.lyx: Moved and added some sections, small changes
3738 all over. Telling LaTeX to be less strict with word spacing
3739 to better keep the right margin. Changed some notes about
3740 maintainance of the ports in section 3.2.1 - is it OK like this?
3742 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3744 SDCC source changes:
3745 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3778 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
3779 UPPER for immediate operands,
3780 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3782 * src/pic16/peeph.def: all peepholes with movff are commented out,
3783 because there is a problem in the pcode peep optimizer,
3784 * src/pic16/ralloc.c: the register allocator can now reuse local
3785 function symbols for another function. This saves register usage.
3786 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3788 Added file src/pic16/NOTES with information about program writing on
3789 the current port version.

3798 * src/SDCCmain.c : fixed #872250: -l command line defined library
3799 files are scanned before standard library files
3801 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3818 gen51Code): more efficient parameter receive for --model-large
3821 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3824 * src/z80/main.c: added missed needLinkerScript flags (more than
3825 one port structure defined in these file)
3826 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
3829 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

3842 needLinkerScript flag
3844 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3845 * src/pic/glue.c: added variable udata_section_name to
3846 override default uninitialized data segment definition for
3847 devices only with SHAREBANK memory (reported from Erik Epetrich)
3848 * (pic14emitOverlay): modified to emit a commented overlay segment
3849 directive when no overlay data exist
3850 * (picglue): modified to emit uninitialized data segment
3851 according to udata_section_name

3857 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3858 object file from '.rel' to '.o' in port->linker structure,
3859 changed size of fptr from 2 to 3 in port structure
3861 2004-01-07 Borut Razem <borut.razem AT siol.net>
3863 * support/scripts/sdcc.nsi: update PATH
3864 * support/scripts/sdcc.ico: craeted
3866 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3869 * doc/Makefile: fix install
3871 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3873 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3875 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3876 how the function variable allocation summary is displayed; also
3877 include information about variables allocated to the overlay
3880 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3882 * as/mcs51/lkmain.c: Help about -Y option

3894 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3896 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3897 (default behaviour).
3899 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3901 A python script to validate compiler diagnostic messages. It can be
3902 used to verify that sdcc complains about bad c source code and
3903 gives a good location of the error.
3904 * support/valdiag/Makefile,
3905 * support/valdiag/valdiag.py,
3906 * support/valdiag/tests/*
3908 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3910 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3911 * src/SDCCsymt.c (newEnumType),

3919 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3921 * src/common.h: added ifndef/define/endif macros
3922 around the header file.
3923 Bug reported from Jesus Calvino-Fraga
3925 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3927 * sdcc.spec: updated
3928 * device/include/Makefile.in: don't install CVS directories
3929 * device/lib/Makefile.in: added removal of CVS directories after install
3930 * doc/Makefile: fixed install, added local_icons
3931 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3932 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3933 * src/ds390/gen.c (genRightShift): fixed bug #870788
3934 * src/SDCCast.c (decorateType): fixed bug #870781
3936 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3938 PIC16 port related changes:
3939 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3940 added variable stackPos,
3942 * gen.c: genCall, assignResultValue: added support for
3943 pushing/retrieving function parameters to/from stack,
3944 genFunction,genEndFunction: setup stack frame for the
3946 genAddrOf: will be changed according to bug 863624
3948 * added files genutils.c and genutils.h which contain gen*
3949 debugged and optimised functions extracted from gen.c
3951 * glue.c: added variable 'externs' which holds extern symbols,
3952 pic16emitRegularMap: is modified to properly handle relocatable
3953 symbols under the new scheme,
3954 pic16createInterruptVect: is modified
3955 pic16printPublics: is modified to emit 'global' assembler directives,
3956 added pic16_printExterns to print extern symbols,
3957 pic16glue: initializes stack/frame pointer in the beginning of
3958 the assembly output. Temporary hack, will be corrected later,
3959 because gplink yet does not support stack and SDCC does not
3960 yet support a type of crt0.o object to create the final binary.
3962 * Removed many lines that contain 8051 legacy code.
3963 * The code is finally placed under a 'code' directive.
3964 * Added port specific options.
3966 * _process_pragma: simplified since now we do not need *special*
3967 include file to define SFR registers. But a separate header
3968 will be needed. This will be developed later.
3969 * _pic16_parseOptions: added, parses port specific options:
3970 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3971 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3972 --preplace-udata-with=
3974 * _pic16_setDefaultOptions: modified to initialize section names,
3975 but hack is temporarly out of order since it needs improvement.
3976 * _pic16_genAssemblerPreamble: configuration words are emitted by
3977 their address instead of their name. This part is incomplete and
3978 supports only the 18Fxx2 devices. Other devices will emit an error
3979 during assembly since they do not contain the same set of config
3981 * _pic16_genIVT: is modified,
3983 * pcode.c: added definitions for some hardware registers that are needed
3985 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3986 All PCI entries are updated. Now LFSR is supported.
3987 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3988 * added pic16_newpCodeOpLit2 to support instructions with
3989 two literal arguments
3990 * pic16_pCode2str: corrected code that emits assembler instructions
3991 with two literal operands and those that have an access bit modifier
3992 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3993 this fixes a bug which caused some labels to be lost, when an
3994 assembler directive was added, i.e. banksel,
3995 * pic16_FixRegisterBanking: improved logic that causes the insertion
3997 * InlineFunction: functions that are called once, are not any more
3998 inlined. This can be a port option in the future,
4000 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4002 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4003 hold the corresponding uninitialized symbols,
4004 * pic16_allocProcessorRegister: registers have explicit marked the
4006 * pic16_allocInternalRegister: registers are explicit marked as
4008 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4009 processing list, so bit registers were lost,
4012 * ralloc.h: added field 'accessBank' and original symbol operand
4013 in register definition,
4014 * removed the field isMapped from register definition,
4016 ** Several functions have been removed from various sources:
4017 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4018 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4019 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4020 pic16_assignRelocatableRegisters
4022 ** others have been introduced:
4023 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4024 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4026 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4028 * support/scripts/inc2h.pl: changed definition of BIT_AT
4029 to emit 'sbit at' instead of 'bit at'. This was a request.
4031 PIC16 port related preliminary changes:
4032 * gen.c: prefixed function popRegFromString with
4033 pic16_ and all references to it corrected
4034 * pcode.c: all pic16_pc_* hardware registers prefixed
4035 with underscore (_),
4036 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4037 * ralloc.c: newReg(): when register is REG_SFR then
4038 set address to rIdx,
4039 pic16_allocProcessorRegister(): marks register wasUsed=0
4040 pic16_writeUsedRegs(): added a call to assign processor
4041 registers via pic16_assignFixedRegisters
4043 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4045 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4046 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4047 variables in unused register banks. Also the SSEG is placed
4048 wherever there is enough space for it, and IDATA can be anywhere
4049 in internal RAM. For now compile using -Wl-Y[stack_size].
4050 The mem file is different for this option as well, since it
4051 makes no sense of talking about DSEG lenght.
4053 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4055 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4056 in certain cases, e.g. when ROM assignment, patch provided
4057 from Albert den Haan.
4059 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
4061 Many signedness and type propagation fixes:
4062 * src/SDCCicode.c: made geniCodeCast() static
4063 replaced SPEC_ by IS_ (cosmetic)
4064 (operandOperation): fixed div and mod operation
4065 (usualBinaryConversions): added support for promotion of char
4066 (geniCodeMultiply): replaced (unsigned long) by (TYPE_UDWORD)

5062 fetching of the pointer
5063 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5064 copied from genNearPointerSet()
5065 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5066 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5067 If they pop r0/r1 they must be called in the opposite order than aopOp().
5068 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5069 (resp. --stack-auto), prepared for --xstack

5080 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5082 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5083 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5084 type for bits was changed. It resulted in bit variables becoming
5085 global, which is not permitted in PIC 14 assembly output.
5087 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5089 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5091 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5093 Z80 and MCS51 linkers complaint if a public symbol is defined

5102 A few small changes that speed up the peephole optimizer.
5106 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5108 Try to make the peephole optimizer smarter by maintaining
5109 an association between the assembly source code and the
5110 iCodes that originated them. Put this information to use
5111 with a new peephole rule condition "notVolatile" so that
5112 the rules can be aggressive yet still safe.
5117 * src/mcs51/peeph.def
5119 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5123 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5124 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5125 if the left or right operand symbols have the accuse flag set.
5127 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5129 Changed the type of the result of the ! (NOT) operator to char;
5130 previously it returned the same type as the source. This allows
5131 us to eliminate all the genFloatNot functions (all of its target
5132 implementations were very buggy) since !float can use the same
5135 * src/SDCCicode.c (ast2iCode): ! returns char
5136 * src/mcs51/gen.c (genNot, genNotFloat),
5137 * src/ds390/gen.c (genNot, genNotFloat),
5138 * src/z80/gen.c (genNot, genNotFloat),
5139 * src/pic/gen.c (genNot, genNotFloat),
5140 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

5144 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5145 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5146 during interrupts. Ensure WSAVE is located at a shared bank address.
5147 2. Fixed page selection in some places
5148 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5149 the registers name strings.
5150 4. Fixed "signed / unsigned compare" compiler warnings.
5151 5. The PIC port manages its own allocation of the general purpose
5152 registers, but makes no attempt to reuse them. As a result when
5153 compiling it soon runs out of general purpose registers. Some
5154 additional code was added to the files pcode.c and device.c to walk
5155 through the function call tree and rename the registers so that they
5165 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5166 genPlus() & genMinus() when the result is the same as left or right

5172 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5174 Made bitfield a distinct type from bit so that bitfields
5175 convert as per ANSI C and bits retain their traditional
5176 boolean style behaviour. Implemented bitfield support in
5184 * src/ds390/gen.c: bit v bitfield split
5185 * src/z80/gen.c: New support for bitfields
5186 * support/regression/tests/bitfields.c: reenabled z80,
5189 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5191 Rules 246.x, 247.x relate to bitfields, the others speed up
5192 access to xdata mapped I/O devices.
5194 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5196 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5198 Cleaned up genPackBits and genUnpackBits and added two helper
5199 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5200 for literal assignments in genPackBits (thanks to Frieder for
5206 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5208 Fixed bug #748310 (pointer to function type mishandled when the
5209 function name is omitted). Also fixed a SIGSEGV when a function
5210 attribute (reentrant, etc) is used on a non-function or on a
5211 function but misplaced before the parameter list.
5213 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5215 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5238 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5240 Made the constant following the "interrupt" keyword optional. If
5241 omitted, the function will not automatically be given an entry
5242 in the interrupt vector table (similar to #pragma NOIV, but
5243 less syntacticly kludgy). The interrupt number is also now
5244 range checked. Also fixed a bug in the high order bit example

5258 * src/SDCCicode.c (operandOperation): rewritten some ops
5259 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5260 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5262 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5263 be re-activated by defining REDUCE_LITERALS)
5264 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5265 unsigned, but are signed by default
5266 * src/SDCCval.c (constVal): rearranged
5267 * src/SDCCval.c (valMod): preliminary fix
5268 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5720 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5721 the regression tests I'm not brave enough to enable 245.b, 245.c
5722 * doc/sdccman.lyx: added latex preamble for hyperref package.
5723 Using pdflatex this will give you a hyperlinked pdf file with
5724 bookmarks. (prepend '%' before /usepackage if this breaks something)

5762 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5764 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5765 it can be defined with CFLAGS when running configure
5766 * src/SDCCmain.c: fixed compiling + linking with object files
5768 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5771 added --disable-pic16-port
5772 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5773 * src/SDCCmain.c: linkOptions is changed to set *,
5774 added if/endif conditional macros to remove options help
5775 messages from optionsTable when a port is not configured, added
5776 support for the PIc16 port in the ports table, when executing
5777 the compiler with no port specified on command line, a default
5778 port is selected with the new macro DEFAULT_PORT which is
5779 defined in port.h, in setDefaultOptions() linkOptions is removed
5780 from initialization assignment, since now it is a set,
5781 parseCmdLine uses setParseWithComma for linkOptions, in
5782 linkEdit() linkOptions are accessed with new function indexSet()
5783 which returns the i'th item of a set variable. See SDCCset.c, in
5784 linkEdit() when calling buildCmdLine(), added linkOptions as
5785 last argument. Now users can pass arguments to gplink via the
5786 -Wl option, main() uses pic16glue() to glue up pic16 programs

5798 * src/pic16/glue.c: commented out some error producing lines
5799 * src/pic16/main.c: __config directives are commented out to stop
5800 gpasm complaining and test the linkage with gplink, _linkCmd and
5801 _asmCmd changed to be more gplink and gpasm friendly
5802 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5803 produced an error when parsed, peep rule 12 is added to utilize
5804 movff, but it is commented out since the pCode does not support
5805 yet a command with 2 address arguments
5807 2003-05-18 <johan AT balder>
5809 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5810 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5834 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5836 2003-05-11 Borut Razem <borut.razem AT siol.net>
5838 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5839 the path of bin directory, so that PATH is the only env. variable, which has to be set
5840 in case of standard installation.
5841 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6870 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6872 * in \sdcc\as\mcs51\ changed these files in order to create an
6873 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6874 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6875 following files to include the previous two files: aslink.dsp,
6876 Makefile.aslink, Makefile.bcc, and Makefile.in.
6878 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6879 .adb instead of .cdb
6881 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6883 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6884 value from option --iram-size.
6886 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6888 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6891 2002-09-18 <wiml AT hhhh.org>
6893 * SDCClrange.h: exposed setFromRange() and setToRange()
6894 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6895 packRegsForAccUse() (bug 542397)
6896 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6897 multiple times and emitting the fetch operations more than once
6898 added aopGetUsesAcc() function to allow binary operators to
6899 fetch their operands in the correct order; made genMinus() emit
6900 compact code for X = LITERAL - Y
6902 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6903 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6904 sprintf() in line 1267.
6906 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6907 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6910 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6911 Changes to aslink (All the changes are marked with 'JCF'):
6913 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6916 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6917 area BSEG. Also moves, if possible, the DATA area down into the internal
6918 ram so more space is available.
6920 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6923 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6924 not bytes. Function summary() which creates a memory usage summary
6925 file with extension .mem. Reports of overlaping stack and small stack
6926 size. If the space for the stack is less than 16 bytes aslink trows a
6929 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6930 the 8051. Option 'y' for memory summary output file.
6932 Changes to sdcc (All the changes are marked with 'JCF'):
6934 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6936 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6937 overlaying area for it (uses RegBankUsed[4]).
6939 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6940 bank zero as used by default. By default aslink locates the stack
6941 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6942 the creation of the .mem file. Delegates the allocation of data area
6943 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6944 the begining of the stack area to aslink.
6946 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6947 glue() in SDCCglue.c creates an area for it.
6949 2002-09-03 Borut Razem <borut.razem AT siol.net>
6950 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6951 sdcc/src/pic/glue.c:
6952 introduced atexit() handler for teporay files removal in case of
6953 errors, assertions, ...
6955 2002-08-29 Borut Razem <borut.razem AT siol.net>
6956 * sdcc/support/cpp2/auto-host_vc_in.h:
6957 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6958 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6959 Maybe there is a similar problem with BORLANDC? It should be checked!
6961 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6962 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6963 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6964 was not executed, and the compiler (cl) launched a warning:
6965 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6967 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6968 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6970 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

6977 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6978 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6979 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6980 - added Release configuration in VS projects
6981 - review of compiler an linker options
6982 - VC .exe files are generated in bin_vc directory, not to interfere
6983 with binaries generated from other projects (cygwin, mingw, bcc ...)
6985 * sdcc/src/yacc.dsp: added
6987 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6988 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6989 and insert the version number definitions from .version
6991 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6993 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

6999 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7000 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7002 2002-08-11 Borut Razem <borut.razem AT siol.net>
7003 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7005 2002-08-10 Borut Razem <borut.razem AT siol.net>
7006 * src/SDCCmain.c (main):
7007 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7008 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7009 The consequence was that some temporary files were not removed.
7012 unification of code in functions tempfilename() and tempfile():
7013 function tempnam() is defined in Visual Studio 6.0 and .NET
7015 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7017 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7018 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7019 - removed compiler command line option /WX: Treats all warnings as errors
7020 - update a list of source files, included into the project
7022 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7023 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7024 changed project type to Generic Project so that can be correcly converted to VS.NET project
7026 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7028 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7032 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7033 added return 0 statements after assert() to make compiler happy
7035 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7036 added newline in the def file to keep MSC compiler satisfied
7038 * sdcc/src/z80/gen.c:
7039 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7040 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7041 - solved MSC error in function aopDump()
7043 * sdcc_vc.h: define PREFIX as "\\sdcc"
7045 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7101 were not getting allocated.
7103 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7106 Fixed left shift. Will promote the left side of a left shift
7107 if a) left shifting more than size of operand or b) when assigned
7108 to something size > size of left side
7110 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7220 * sdcc/src/SDCCloop.c:
7221 Previous fix was not good. basic blocks that have "break" or "return" are
7222 not really partof a loop , but live ranges used in these blocks should
7223 be live thru the entire loop, so set partOfLoop but don't add them to
7226 2002-02-21 <johan AT FRIJA>
