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

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

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

595 * (isBankInstruction): modified to return 0 for no banking instruction,
596 and 1 for banking instruction,

598 caused stop processing pCodes after a inline assembly block,
599 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3577 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3580 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3581 strtof is not part of C89 and isn't included with Mac OS X.
3583 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3607 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
3610 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3612 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3613 loaded with the linker search paths (-L arguments) and the libraries
3614 to be linked with the current source (-l arguments). Changes
3615 currently will affect only the pic16 port.
3616 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3617 include path the port specific paths and port specific libraries,
3618 * gplink command now contains the $3 argument,
3619 * src/pic16/device.h,
3620 * src/pic16/device.c,: structure PIC_device is made public and
3621 renamed to PIC16_device, the same for variable Pics which is renamed
3622 to Pics16. Updated all references to them.
3623 * src/pic16/glue.c (pic16glue): corrected bug with code
3624 initialization which bypassed the variable initializations block.
3626 * device/lib/pic16/Makefile.rules: removed --penable-stack from

3634 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3636 Documenting changes from previous commits.
3637 * configure.in (version 1.56),
3638 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3639 when generating output files to configure the pic16 library,
3640 but now I've commented it out, since gputils aren't installed in the
3641 SF compile farm, so library won't compile
3643 * device/lib/Makefile.in (version 1.56): initially I've added in
3644 target 'all' the prerequestive 'model-pic16' so it compiled the
3645 pic16 library, but now I've commented it out for the same reasons
3647 * added targets 'model-pic16' and 'objects-pic16' to compile the
3649 * added target 'port-specific-objects-pic16' to handle the
3650 generated libraries and copy them into the build/ directory
3651 * added target 'clean-intermediate-pic16' to clean intermediate
3652 files into pic16 directory
3653 * in target 'installdirs' added line to create directory pic16 in
3654 the installation path
3656 * device/include/Makefile.in (version 1.11): in target 'install'
3657 added lines to copy all header files to installation path,
3658 * in target 'installdirs' added line create directory for pic16
3659 headers in the installation path

3674 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3675 option so that it actually works. Made it specific to the z80, since
3676 the gbz80 doesn't have these kinds of I/O ports.
3678 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3680 * device/include/z180.h,

3693 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3695 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3696 changed interrupt vector table generation to only emit declared vectors.
3697 * device/include/Makefile.in: added missing backslash
3698 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
3700 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3702 Mainly changes to support compilation of the device libraries
3703 * src/pic16/device.c: stack is allocated via symbol and not
3704 via literal number. The symbol is placed in the corresponding
3705 position of the data ram
3706 * (pic16_dump_section): relocatable and absolute uninitialized
3707 data are now emitted in sorted order to reduce section naming,
3708 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3709 weren't marked as being in the access bank,
3711 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3713 Added portion of GNU PIC Library under the directory
3714 device/include/pic16 and device/lib/pic16. These files
3715 contain the declarations of SFRs for the PIC18Fxx2 devices.
3716 The directory is initialized via configure from toplevel.
3718 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3720 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3721 the spilllocations to be compared correctly
3723 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3725 * src/SDCCast.c (decorateType): fixed bug introduced today
3727 2004-01-12 Borut Razem <borut.razem AT siol.net>
3729 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3732 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3734 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3735 in simpler and even better code
3737 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3739 * src/SDCCicode.c (operandOperation): fixed bug #874819

3743 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3745 * doc/sdccman.lyx: Moved and added some sections, small changes
3746 all over. Telling LaTeX to be less strict with word spacing
3747 to better keep the right margin. Changed some notes about
3748 maintainance of the ports in section 3.2.1 - is it OK like this?
3750 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3752 SDCC source changes:
3753 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3786 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
3787 UPPER for immediate operands,
3788 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3790 * src/pic16/peeph.def: all peepholes with movff are commented out,
3791 because there is a problem in the pcode peep optimizer,
3792 * src/pic16/ralloc.c: the register allocator can now reuse local
3793 function symbols for another function. This saves register usage.
3794 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3796 Added file src/pic16/NOTES with information about program writing on
3797 the current port version.

3806 * src/SDCCmain.c : fixed #872250: -l command line defined library
3807 files are scanned before standard library files
3809 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3826 gen51Code): more efficient parameter receive for --model-large
3829 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3832 * src/z80/main.c: added missed needLinkerScript flags (more than
3833 one port structure defined in these file)
3834 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3850 needLinkerScript flag
3852 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3853 * src/pic/glue.c: added variable udata_section_name to
3854 override default uninitialized data segment definition for
3855 devices only with SHAREBANK memory (reported from Erik Epetrich)
3856 * (pic14emitOverlay): modified to emit a commented overlay segment
3857 directive when no overlay data exist
3858 * (picglue): modified to emit uninitialized data segment
3859 according to udata_section_name

3864 arguments via -W option
3865 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3866 object file from '.rel' to '.o' in port->linker structure,
3867 changed size of fptr from 2 to 3 in port structure
3869 2004-01-07 Borut Razem <borut.razem AT siol.net>
3871 * support/scripts/sdcc.nsi: update PATH
3872 * support/scripts/sdcc.ico: craeted
3874 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
3876 * device/include/Makefile.in: fix install
3877 * doc/Makefile: fix install
3879 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3881 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3883 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
3884 how the function variable allocation summary is displayed; also
3885 include information about variables allocated to the overlay
3888 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3890 * as/mcs51/lkmain.c: Help about -Y option

3900 LEFT_OP (left shift)
3902 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3904 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3905 (default behaviour).
3907 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3909 A python script to validate compiler diagnostic messages. It can be
3910 used to verify that sdcc complains about bad c source code and
3911 gives a good location of the error.
3912 * support/valdiag/Makefile,
3913 * support/valdiag/valdiag.py,
3914 * support/valdiag/tests/*
3916 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3918 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3919 * src/SDCCsymt.c (newEnumType),

3927 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3929 * src/common.h: added ifndef/define/endif macros
3930 around the header file.
3931 Bug reported from Jesus Calvino-Fraga
3933 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3935 * sdcc.spec: updated
3936 * device/include/Makefile.in: don't install CVS directories
3937 * device/lib/Makefile.in: added removal of CVS directories after install
3938 * doc/Makefile: fixed install, added local_icons
3939 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3940 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3941 * src/ds390/gen.c (genRightShift): fixed bug #870788
3942 * src/SDCCast.c (decorateType): fixed bug #870781
3944 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3946 PIC16 port related changes:
3947 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3948 added variable stackPos,
3950 * gen.c: genCall, assignResultValue: added support for
3951 pushing/retrieving function parameters to/from stack,
3952 genFunction,genEndFunction: setup stack frame for the
3954 genAddrOf: will be changed according to bug 863624
3956 * added files genutils.c and genutils.h which contain gen*
3957 debugged and optimised functions extracted from gen.c
3959 * glue.c: added variable 'externs' which holds extern symbols,
3960 pic16emitRegularMap: is modified to properly handle relocatable
3961 symbols under the new scheme,
3962 pic16createInterruptVect: is modified
3963 pic16printPublics: is modified to emit 'global' assembler directives,
3964 added pic16_printExterns to print extern symbols,
3965 pic16glue: initializes stack/frame pointer in the beginning of
3966 the assembly output. Temporary hack, will be corrected later,
3967 because gplink yet does not support stack and SDCC does not
3968 yet support a type of crt0.o object to create the final binary.
3970 * Removed many lines that contain 8051 legacy code.
3971 * The code is finally placed under a 'code' directive.
3972 * Added port specific options.
3974 * _process_pragma: simplified since now we do not need *special*
3975 include file to define SFR registers. But a separate header
3976 will be needed. This will be developed later.
3977 * _pic16_parseOptions: added, parses port specific options:
3978 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3979 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3980 --preplace-udata-with=
3982 * _pic16_setDefaultOptions: modified to initialize section names,
3983 but hack is temporarly out of order since it needs improvement.
3984 * _pic16_genAssemblerPreamble: configuration words are emitted by
3985 their address instead of their name. This part is incomplete and
3986 supports only the 18Fxx2 devices. Other devices will emit an error
3987 during assembly since they do not contain the same set of config
3989 * _pic16_genIVT: is modified,
3991 * pcode.c: added definitions for some hardware registers that are needed
3993 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3994 All PCI entries are updated. Now LFSR is supported.
3995 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3996 * added pic16_newpCodeOpLit2 to support instructions with
3997 two literal arguments
3998 * pic16_pCode2str: corrected code that emits assembler instructions
3999 with two literal operands and those that have an access bit modifier
4000 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4001 this fixes a bug which caused some labels to be lost, when an
4002 assembler directive was added, i.e. banksel,
4003 * pic16_FixRegisterBanking: improved logic that causes the insertion
4005 * InlineFunction: functions that are called once, are not any more
4006 inlined. This can be a port option in the future,
4008 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4010 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4011 hold the corresponding uninitialized symbols,
4012 * pic16_allocProcessorRegister: registers have explicit marked the
4014 * pic16_allocInternalRegister: registers are explicit marked as
4016 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4017 processing list, so bit registers were lost,
4020 * ralloc.h: added field 'accessBank' and original symbol operand
4021 in register definition,
4022 * removed the field isMapped from register definition,
4024 ** Several functions have been removed from various sources:
4025 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4026 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4027 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4028 pic16_assignRelocatableRegisters
4030 ** others have been introduced:
4031 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4032 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4034 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4036 * support/scripts/inc2h.pl: changed definition of BIT_AT
4037 to emit 'sbit at' instead of 'bit at'. This was a request.
4039 PIC16 port related preliminary changes:
4040 * gen.c: prefixed function popRegFromString with
4041 pic16_ and all references to it corrected
4042 * pcode.c: all pic16_pc_* hardware registers prefixed
4043 with underscore (_),
4044 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4045 * ralloc.c: newReg(): when register is REG_SFR then
4046 set address to rIdx,
4047 pic16_allocProcessorRegister(): marks register wasUsed=0
4048 pic16_writeUsedRegs(): added a call to assign processor
4049 registers via pic16_assignFixedRegisters
4051 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4053 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4054 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4055 variables in unused register banks. Also the SSEG is placed
4056 wherever there is enough space for it, and IDATA can be anywhere
4057 in internal RAM. For now compile using -Wl-Y[stack_size].
4058 The mem file is different for this option as well, since it
4059 makes no sense of talking about DSEG lenght.
4061 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4063 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5063 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5064 before instructions that use the _STATUS register
5066 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5068 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5069 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5070 fetching of the pointer
5071 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5072 copied from genNearPointerSet()
5073 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5074 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5075 If they pop r0/r1 they must be called in the opposite order than aopOp().
5076 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5077 (resp. --stack-auto), prepared for --xstack

5088 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5090 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5091 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5092 type for bits was changed. It resulted in bit variables becoming
5093 global, which is not permitted in PIC 14 assembly output.
5095 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5097 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5099 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5101 Z80 and MCS51 linkers complaint if a public symbol is defined

5110 A few small changes that speed up the peephole optimizer.
5114 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5116 Try to make the peephole optimizer smarter by maintaining
5117 an association between the assembly source code and the
5118 iCodes that originated them. Put this information to use
5119 with a new peephole rule condition "notVolatile" so that
5120 the rules can be aggressive yet still safe.
5125 * src/mcs51/peeph.def
5127 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5131 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5132 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5133 if the left or right operand symbols have the accuse flag set.
5135 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5137 Changed the type of the result of the ! (NOT) operator to char;
5138 previously it returned the same type as the source. This allows
5139 us to eliminate all the genFloatNot functions (all of its target
5140 implementations were very buggy) since !float can use the same
5143 * src/SDCCicode.c (ast2iCode): ! returns char

5145 * src/ds390/gen.c (genNot, genNotFloat),
5146 * src/z80/gen.c (genNot, genNotFloat),
5147 * src/pic/gen.c (genNot, genNotFloat),

5152 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5153 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5154 during interrupts. Ensure WSAVE is located at a shared bank address.
5155 2. Fixed page selection in some places
5156 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5157 the registers name strings.
5158 4. Fixed "signed / unsigned compare" compiler warnings.
5159 5. The PIC port manages its own allocation of the general purpose
5160 registers, but makes no attempt to reuse them. As a result when
5161 compiling it soon runs out of general purpose registers. Some
5162 additional code was added to the files pcode.c and device.c to walk
5163 through the function call tree and rename the registers so that they
5173 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5174 genPlus() & genMinus() when the result is the same as left or right

5180 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5182 Made bitfield a distinct type from bit so that bitfields
5183 convert as per ANSI C and bits retain their traditional
5184 boolean style behaviour. Implemented bitfield support in
5192 * src/ds390/gen.c: bit v bitfield split
5193 * src/z80/gen.c: New support for bitfields
5194 * support/regression/tests/bitfields.c: reenabled z80,
5197 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5199 Rules 246.x, 247.x relate to bitfields, the others speed up
5200 access to xdata mapped I/O devices.
5202 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5204 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5206 Cleaned up genPackBits and genUnpackBits and added two helper
5207 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5208 for literal assignments in genPackBits (thanks to Frieder for
5214 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5216 Fixed bug #748310 (pointer to function type mishandled when the
5217 function name is omitted). Also fixed a SIGSEGV when a function
5218 attribute (reentrant, etc) is used on a non-function or on a
5219 function but misplaced before the parameter list.
5221 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5223 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5224 * support/Util/SDCCerr.h,

5246 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5248 Made the constant following the "interrupt" keyword optional. If
5249 omitted, the function will not automatically be given an entry
5250 in the interrupt vector table (similar to #pragma NOIV, but
5251 less syntacticly kludgy). The interrupt number is also now
5252 range checked. Also fixed a bug in the high order bit example

5266 * src/SDCCicode.c (operandOperation): rewritten some ops
5267 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5268 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5270 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5271 be re-activated by defining REDUCE_LITERALS)
5272 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5273 unsigned, but are signed by default
5274 * src/SDCCval.c (constVal): rearranged
5275 * src/SDCCval.c (valMod): preliminary fix
5276 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5781 * src/SDCCmain.c: linkOptions is changed to set *,
5782 added if/endif conditional macros to remove options help
5783 messages from optionsTable when a port is not configured, added
5784 support for the PIc16 port in the ports table, when executing
5785 the compiler with no port specified on command line, a default
5786 port is selected with the new macro DEFAULT_PORT which is
5787 defined in port.h, in setDefaultOptions() linkOptions is removed
5788 from initialization assignment, since now it is a set,
5789 parseCmdLine uses setParseWithComma for linkOptions, in
5790 linkEdit() linkOptions are accessed with new function indexSet()
5791 which returns the i'th item of a set variable. See SDCCset.c, in
5792 linkEdit() when calling buildCmdLine(), added linkOptions as
5793 last argument. Now users can pass arguments to gplink via the
5794 -Wl option, main() uses pic16glue() to glue up pic16 programs

5806 * src/pic16/glue.c: commented out some error producing lines
5807 * src/pic16/main.c: __config directives are commented out to stop
5808 gpasm complaining and test the linkage with gplink, _linkCmd and
5809 _asmCmd changed to be more gplink and gpasm friendly
5810 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5811 produced an error when parsed, peep rule 12 is added to utilize
5812 movff, but it is commented out since the pCode does not support
5813 yet a command with 2 address arguments
5815 2003-05-18 <johan AT balder>
5817 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5844 2003-05-11 Borut Razem <borut.razem AT siol.net>
5846 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5847 the path of bin directory, so that PATH is the only env. variable, which has to be set
5848 in case of standard installation.

6878 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6880 * in \sdcc\as\mcs51\ changed these files in order to create an
6881 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6882 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6883 following files to include the previous two files: aslink.dsp,
6884 Makefile.aslink, Makefile.bcc, and Makefile.in.
6886 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6887 .adb instead of .cdb
6889 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6891 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6892 value from option --iram-size.
6894 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6896 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6899 2002-09-18 <wiml AT hhhh.org>
6901 * SDCClrange.h: exposed setFromRange() and setToRange()
6902 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6903 packRegsForAccUse() (bug 542397)
6904 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6905 multiple times and emitting the fetch operations more than once
6906 added aopGetUsesAcc() function to allow binary operators to
6907 fetch their operands in the correct order; made genMinus() emit
6908 compact code for X = LITERAL - Y
6910 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6911 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6912 sprintf() in line 1267.
6914 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6915 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6918 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6919 Changes to aslink (All the changes are marked with 'JCF'):
6921 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6924 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6925 area BSEG. Also moves, if possible, the DATA area down into the internal
6926 ram so more space is available.
6928 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6931 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6932 not bytes. Function summary() which creates a memory usage summary
6933 file with extension .mem. Reports of overlaping stack and small stack
6934 size. If the space for the stack is less than 16 bytes aslink trows a
6937 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6938 the 8051. Option 'y' for memory summary output file.
6940 Changes to sdcc (All the changes are marked with 'JCF'):
6942 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6944 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6945 overlaying area for it (uses RegBankUsed[4]).
6947 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6948 bank zero as used by default. By default aslink locates the stack
6949 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6950 the creation of the .mem file. Delegates the allocation of data area
6951 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6952 the begining of the stack area to aslink.
6954 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6955 glue() in SDCCglue.c creates an area for it.
6957 2002-09-03 Borut Razem <borut.razem AT siol.net>
6958 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6959 sdcc/src/pic/glue.c:
6960 introduced atexit() handler for teporay files removal in case of
6961 errors, assertions, ...
6963 2002-08-29 Borut Razem <borut.razem AT siol.net>
6964 * sdcc/support/cpp2/auto-host_vc_in.h:
6965 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6966 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6967 Maybe there is a similar problem with BORLANDC? It should be checked!
6969 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6970 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6971 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6972 was not executed, and the compiler (cl) launched a warning:
6973 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6975 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6976 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

6982 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6983 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6984 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6985 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6986 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6987 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6988 - added Release configuration in VS projects
6989 - review of compiler an linker options
6990 - VC .exe files are generated in bin_vc directory, not to interfere
6991 with binaries generated from other projects (cygwin, mingw, bcc ...)
6993 * sdcc/src/yacc.dsp: added
6995 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6996 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6997 and insert the version number definitions from .version
6999 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7001 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7011 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7013 2002-08-10 Borut Razem <borut.razem AT siol.net>
7014 * src/SDCCmain.c (main):
7015 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7016 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7017 The consequence was that some temporary files were not removed.
7020 unification of code in functions tempfilename() and tempfile():
7021 function tempnam() is defined in Visual Studio 6.0 and .NET
7023 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7025 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7026 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

7041 added return 0 statements after assert() to make compiler happy
7043 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7044 added newline in the def file to keep MSC compiler satisfied
7046 * sdcc/src/z80/gen.c:
7047 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7048 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7049 - solved MSC error in function aopDump()
7051 * sdcc_vc.h: define PREFIX as "\\sdcc"
7053 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7109 were not getting allocated.
7111 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7114 Fixed left shift. Will promote the left side of a left shift
7115 if a) left shifting more than size of operand or b) when assigned
7116 to something size > size of left side
7118 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7228 * sdcc/src/SDCCloop.c:
7229 Previous fix was not good. basic blocks that have "break" or "return" are
7230 not really partof a loop , but live ranges used in these blocks should
7231 be live thru the entire loop, so set partOfLoop but don't add them to
7234 2002-02-21 <johan AT FRIJA>
