530 Adding support for replacing ljmps with sjmps in jumptables
531 generated for switch statements. For now you need to set the
532 environment variable SDCC_SJMP_JUMPTABLE to enable this.
533 Now 4 algorithms for mcs51 jumptable generation are used:
534 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
535 addresses loaded pc-relative for up to 112 cases and stack-pushing
536 target addresses loaded with offset from dptr for up to 256 cases.

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

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

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

3581 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3584 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3585 strtof is not part of C89 and isn't included with Mac OS X.
3587 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3614 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3616 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3617 loaded with the linker search paths (-L arguments) and the libraries
3618 to be linked with the current source (-l arguments). Changes
3619 currently will affect only the pic16 port.
3620 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3621 include path the port specific paths and port specific libraries,
3622 * gplink command now contains the $3 argument,
3623 * src/pic16/device.h,
3624 * src/pic16/device.c,: structure PIC_device is made public and
3625 renamed to PIC16_device, the same for variable Pics which is renamed
3626 to Pics16. Updated all references to them.
3627 * src/pic16/glue.c (pic16glue): corrected bug with code
3628 initialization which bypassed the variable initializations block.

3638 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3640 Documenting changes from previous commits.
3641 * configure.in (version 1.56),
3642 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3643 when generating output files to configure the pic16 library,
3644 but now I've commented it out, since gputils aren't installed in the
3645 SF compile farm, so library won't compile
3647 * device/lib/Makefile.in (version 1.56): initially I've added in
3648 target 'all' the prerequestive 'model-pic16' so it compiled the
3649 pic16 library, but now I've commented it out for the same reasons
3651 * added targets 'model-pic16' and 'objects-pic16' to compile the
3653 * added target 'port-specific-objects-pic16' to handle the
3654 generated libraries and copy them into the build/ directory
3655 * added target 'clean-intermediate-pic16' to clean intermediate
3656 files into pic16 directory
3657 * in target 'installdirs' added line to create directory pic16 in
3658 the installation path
3660 * device/include/Makefile.in (version 1.11): in target 'install'
3661 added lines to copy all header files to installation path,
3662 * in target 'installdirs' added line create directory for pic16
3663 headers in the installation path

3678 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3679 option so that it actually works. Made it specific to the z80, since
3680 the gbz80 doesn't have these kinds of I/O ports.
3682 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3684 * device/include/z180.h,

3697 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3699 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3700 changed interrupt vector table generation to only emit declared vectors.
3701 * device/include/Makefile.in: added missing backslash
3702 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

3706 Mainly changes to support compilation of the device libraries
3707 * src/pic16/device.c: stack is allocated via symbol and not
3708 via literal number. The symbol is placed in the corresponding
3709 position of the data ram
3710 * (pic16_dump_section): relocatable and absolute uninitialized
3711 data are now emitted in sorted order to reduce section naming,
3712 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3713 weren't marked as being in the access bank,
3715 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3717 Added portion of GNU PIC Library under the directory
3718 device/include/pic16 and device/lib/pic16. These files
3719 contain the declarations of SFRs for the PIC18Fxx2 devices.
3720 The directory is initialized via configure from toplevel.
3722 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3724 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3725 the spilllocations to be compared correctly
3727 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3729 * src/SDCCast.c (decorateType): fixed bug introduced today
3731 2004-01-12 Borut Razem <borut.razem AT siol.net>
3733 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3736 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3738 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3739 in simpler and even better code
3741 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3743 * src/SDCCicode.c (operandOperation): fixed bug #874819

3747 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3749 * doc/sdccman.lyx: Moved and added some sections, small changes
3750 all over. Telling LaTeX to be less strict with word spacing
3751 to better keep the right margin. Changed some notes about
3752 maintainance of the ports in section 3.2.1 - is it OK like this?
3754 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
3756 SDCC source changes:
3757 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

3791 UPPER for immediate operands,
3792 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3794 * src/pic16/peeph.def: all peepholes with movff are commented out,
3795 because there is a problem in the pcode peep optimizer,
3796 * src/pic16/ralloc.c: the register allocator can now reuse local
3797 function symbols for another function. This saves register usage.
3798 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3800 Added file src/pic16/NOTES with information about program writing on
3801 the current port version.

3810 * src/SDCCmain.c : fixed #872250: -l command line defined library
3811 files are scanned before standard library files
3813 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3830 gen51Code): more efficient parameter receive for --model-large
3833 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3836 * src/z80/main.c: added missed needLinkerScript flags (more than
3837 one port structure defined in these file)
3838 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3854 needLinkerScript flag
3856 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3857 * src/pic/glue.c: added variable udata_section_name to
3858 override default uninitialized data segment definition for
3859 devices only with SHAREBANK memory (reported from Erik Epetrich)
3860 * (pic14emitOverlay): modified to emit a commented overlay segment
3861 directive when no overlay data exist
3862 * (picglue): modified to emit uninitialized data segment
3863 according to udata_section_name

3869 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3870 object file from '.rel' to '.o' in port->linker structure,
3871 changed size of fptr from 2 to 3 in port structure
3873 2004-01-07 Borut Razem <borut.razem AT siol.net>
3875 * support/scripts/sdcc.nsi: update PATH
3876 * support/scripts/sdcc.ico: craeted
3878 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3881 * doc/Makefile: fix install
3883 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3885 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
3887 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

3889 include information about variables allocated to the overlay
3892 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3894 * as/mcs51/lkmain.c: Help about -Y option

3906 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3908 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3909 (default behaviour).
3911 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3913 A python script to validate compiler diagnostic messages. It can be
3914 used to verify that sdcc complains about bad c source code and
3915 gives a good location of the error.
3916 * support/valdiag/Makefile,
3917 * support/valdiag/valdiag.py,
3918 * support/valdiag/tests/*
3920 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3922 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3923 * src/SDCCsymt.c (newEnumType),

3931 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3933 * src/common.h: added ifndef/define/endif macros
3934 around the header file.
3935 Bug reported from Jesus Calvino-Fraga
3937 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3939 * sdcc.spec: updated
3940 * device/include/Makefile.in: don't install CVS directories
3941 * device/lib/Makefile.in: added removal of CVS directories after install
3942 * doc/Makefile: fixed install, added local_icons
3943 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3944 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3945 * src/ds390/gen.c (genRightShift): fixed bug #870788
3946 * src/SDCCast.c (decorateType): fixed bug #870781
3948 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3950 PIC16 port related changes:
3951 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3952 added variable stackPos,
3954 * gen.c: genCall, assignResultValue: added support for
3955 pushing/retrieving function parameters to/from stack,
3956 genFunction,genEndFunction: setup stack frame for the
3958 genAddrOf: will be changed according to bug 863624
3960 * added files genutils.c and genutils.h which contain gen*
3961 debugged and optimised functions extracted from gen.c
3963 * glue.c: added variable 'externs' which holds extern symbols,
3964 pic16emitRegularMap: is modified to properly handle relocatable
3965 symbols under the new scheme,
3966 pic16createInterruptVect: is modified
3967 pic16printPublics: is modified to emit 'global' assembler directives,
3968 added pic16_printExterns to print extern symbols,
3969 pic16glue: initializes stack/frame pointer in the beginning of
3970 the assembly output. Temporary hack, will be corrected later,
3971 because gplink yet does not support stack and SDCC does not
3972 yet support a type of crt0.o object to create the final binary.
3974 * Removed many lines that contain 8051 legacy code.
3975 * The code is finally placed under a 'code' directive.
3976 * Added port specific options.
3978 * _process_pragma: simplified since now we do not need *special*
3979 include file to define SFR registers. But a separate header
3980 will be needed. This will be developed later.
3981 * _pic16_parseOptions: added, parses port specific options:
3982 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3983 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3984 --preplace-udata-with=
3986 * _pic16_setDefaultOptions: modified to initialize section names,
3987 but hack is temporarly out of order since it needs improvement.
3988 * _pic16_genAssemblerPreamble: configuration words are emitted by
3989 their address instead of their name. This part is incomplete and
3990 supports only the 18Fxx2 devices. Other devices will emit an error
3991 during assembly since they do not contain the same set of config
3993 * _pic16_genIVT: is modified,
3995 * pcode.c: added definitions for some hardware registers that are needed
3997 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3998 All PCI entries are updated. Now LFSR is supported.
3999 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4000 * added pic16_newpCodeOpLit2 to support instructions with
4001 two literal arguments
4002 * pic16_pCode2str: corrected code that emits assembler instructions
4003 with two literal operands and those that have an access bit modifier
4004 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4005 this fixes a bug which caused some labels to be lost, when an
4006 assembler directive was added, i.e. banksel,
4007 * pic16_FixRegisterBanking: improved logic that causes the insertion
4009 * InlineFunction: functions that are called once, are not any more
4010 inlined. This can be a port option in the future,
4012 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4014 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4015 hold the corresponding uninitialized symbols,
4016 * pic16_allocProcessorRegister: registers have explicit marked the
4018 * pic16_allocInternalRegister: registers are explicit marked as
4020 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4021 processing list, so bit registers were lost,
4024 * ralloc.h: added field 'accessBank' and original symbol operand
4025 in register definition,
4026 * removed the field isMapped from register definition,
4028 ** Several functions have been removed from various sources:
4029 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4030 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4031 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4032 pic16_assignRelocatableRegisters
4034 ** others have been introduced:
4035 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4036 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4038 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4040 * support/scripts/inc2h.pl: changed definition of BIT_AT
4041 to emit 'sbit at' instead of 'bit at'. This was a request.
4043 PIC16 port related preliminary changes:
4044 * gen.c: prefixed function popRegFromString with
4045 pic16_ and all references to it corrected
4046 * pcode.c: all pic16_pc_* hardware registers prefixed
4047 with underscore (_),
4048 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4049 * ralloc.c: newReg(): when register is REG_SFR then
4050 set address to rIdx,
4051 pic16_allocProcessorRegister(): marks register wasUsed=0
4052 pic16_writeUsedRegs(): added a call to assign processor
4053 registers via pic16_assignFixedRegisters
4055 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4057 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4058 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4059 variables in unused register banks. Also the SSEG is placed
4060 wherever there is enough space for it, and IDATA can be anywhere
4061 in internal RAM. For now compile using -Wl-Y[stack_size].
4062 The mem file is different for this option as well, since it
4063 makes no sense of talking about DSEG lenght.
4065 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4067 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5067 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5068 before instructions that use the _STATUS register
5070 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5072 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5073 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5074 fetching of the pointer
5075 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5076 copied from genNearPointerSet()
5077 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5078 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5079 If they pop r0/r1 they must be called in the opposite order than aopOp().
5080 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5081 (resp. --stack-auto), prepared for --xstack

5092 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5094 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5095 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5096 type for bits was changed. It resulted in bit variables becoming
5097 global, which is not permitted in PIC 14 assembly output.
5099 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5101 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5103 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5105 Z80 and MCS51 linkers complaint if a public symbol is defined

5114 A few small changes that speed up the peephole optimizer.
5118 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5120 Try to make the peephole optimizer smarter by maintaining
5121 an association between the assembly source code and the
5122 iCodes that originated them. Put this information to use
5123 with a new peephole rule condition "notVolatile" so that
5124 the rules can be aggressive yet still safe.
5129 * src/mcs51/peeph.def
5131 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5135 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5136 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5137 if the left or right operand symbols have the accuse flag set.
5139 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5141 Changed the type of the result of the ! (NOT) operator to char;
5142 previously it returned the same type as the source. This allows
5143 us to eliminate all the genFloatNot functions (all of its target
5144 implementations were very buggy) since !float can use the same
5147 * src/SDCCicode.c (ast2iCode): ! returns char

5149 * src/ds390/gen.c (genNot, genNotFloat),
5150 * src/z80/gen.c (genNot, genNotFloat),
5151 * src/pic/gen.c (genNot, genNotFloat),

5156 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5157 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5158 during interrupts. Ensure WSAVE is located at a shared bank address.
5159 2. Fixed page selection in some places
5160 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5161 the registers name strings.
5162 4. Fixed "signed / unsigned compare" compiler warnings.
5163 5. The PIC port manages its own allocation of the general purpose
5164 registers, but makes no attempt to reuse them. As a result when
5165 compiling it soon runs out of general purpose registers. Some
5166 additional code was added to the files pcode.c and device.c to walk
5167 through the function call tree and rename the registers so that they
5177 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5178 genPlus() & genMinus() when the result is the same as left or right

5184 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5186 Made bitfield a distinct type from bit so that bitfields
5187 convert as per ANSI C and bits retain their traditional
5188 boolean style behaviour. Implemented bitfield support in
5196 * src/ds390/gen.c: bit v bitfield split
5197 * src/z80/gen.c: New support for bitfields
5198 * support/regression/tests/bitfields.c: reenabled z80,
5201 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5203 Rules 246.x, 247.x relate to bitfields, the others speed up
5204 access to xdata mapped I/O devices.
5206 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5208 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5210 Cleaned up genPackBits and genUnpackBits and added two helper
5211 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5212 for literal assignments in genPackBits (thanks to Frieder for
5218 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5220 Fixed bug #748310 (pointer to function type mishandled when the
5221 function name is omitted). Also fixed a SIGSEGV when a function
5222 attribute (reentrant, etc) is used on a non-function or on a
5223 function but misplaced before the parameter list.
5225 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5227 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5250 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5252 Made the constant following the "interrupt" keyword optional. If
5253 omitted, the function will not automatically be given an entry
5254 in the interrupt vector table (similar to #pragma NOIV, but
5255 less syntacticly kludgy). The interrupt number is also now
5256 range checked. Also fixed a bug in the high order bit example

5270 * src/SDCCicode.c (operandOperation): rewritten some ops
5271 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5272 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5274 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5275 be re-activated by defining REDUCE_LITERALS)
5276 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5277 unsigned, but are signed by default
5278 * src/SDCCval.c (constVal): rearranged
5279 * src/SDCCval.c (valMod): preliminary fix
5280 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5785 * src/SDCCmain.c: linkOptions is changed to set *,
5786 added if/endif conditional macros to remove options help
5787 messages from optionsTable when a port is not configured, added
5788 support for the PIc16 port in the ports table, when executing
5789 the compiler with no port specified on command line, a default
5790 port is selected with the new macro DEFAULT_PORT which is
5791 defined in port.h, in setDefaultOptions() linkOptions is removed
5792 from initialization assignment, since now it is a set,
5793 parseCmdLine uses setParseWithComma for linkOptions, in
5794 linkEdit() linkOptions are accessed with new function indexSet()
5795 which returns the i'th item of a set variable. See SDCCset.c, in
5796 linkEdit() when calling buildCmdLine(), added linkOptions as
5797 last argument. Now users can pass arguments to gplink via the
5798 -Wl option, main() uses pic16glue() to glue up pic16 programs

5810 * src/pic16/glue.c: commented out some error producing lines
5811 * src/pic16/main.c: __config directives are commented out to stop
5812 gpasm complaining and test the linkage with gplink, _linkCmd and
5813 _asmCmd changed to be more gplink and gpasm friendly
5814 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5815 produced an error when parsed, peep rule 12 is added to utilize
5816 movff, but it is commented out since the pCode does not support
5817 yet a command with 2 address arguments
5819 2003-05-18 <johan AT balder>
5821 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5848 2003-05-11 Borut Razem <borut.razem AT siol.net>
5850 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5851 the path of bin directory, so that PATH is the only env. variable, which has to be set
5852 in case of standard installation.

6882 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6884 * in \sdcc\as\mcs51\ changed these files in order to create an
6885 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6886 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6887 following files to include the previous two files: aslink.dsp,
6888 Makefile.aslink, Makefile.bcc, and Makefile.in.
6890 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6891 .adb instead of .cdb
6893 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6895 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6896 value from option --iram-size.
6898 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6900 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6903 2002-09-18 <wiml AT hhhh.org>
6905 * SDCClrange.h: exposed setFromRange() and setToRange()
6906 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6907 packRegsForAccUse() (bug 542397)
6908 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6909 multiple times and emitting the fetch operations more than once
6910 added aopGetUsesAcc() function to allow binary operators to
6911 fetch their operands in the correct order; made genMinus() emit
6912 compact code for X = LITERAL - Y
6914 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6915 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6916 sprintf() in line 1267.
6918 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6919 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6922 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6923 Changes to aslink (All the changes are marked with 'JCF'):
6925 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6928 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6929 area BSEG. Also moves, if possible, the DATA area down into the internal
6930 ram so more space is available.
6932 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6935 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6936 not bytes. Function summary() which creates a memory usage summary
6937 file with extension .mem. Reports of overlaping stack and small stack
6938 size. If the space for the stack is less than 16 bytes aslink trows a
6941 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6942 the 8051. Option 'y' for memory summary output file.
6944 Changes to sdcc (All the changes are marked with 'JCF'):
6946 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6948 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6949 overlaying area for it (uses RegBankUsed[4]).
6951 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6952 bank zero as used by default. By default aslink locates the stack
6953 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6954 the creation of the .mem file. Delegates the allocation of data area
6955 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6956 the begining of the stack area to aslink.
6958 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6959 glue() in SDCCglue.c creates an area for it.
6961 2002-09-03 Borut Razem <borut.razem AT siol.net>
6962 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6963 sdcc/src/pic/glue.c:
6964 introduced atexit() handler for teporay files removal in case of
6965 errors, assertions, ...
6967 2002-08-29 Borut Razem <borut.razem AT siol.net>
6968 * sdcc/support/cpp2/auto-host_vc_in.h:
6969 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6970 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6971 Maybe there is a similar problem with BORLANDC? It should be checked!
6973 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6974 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6975 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6976 was not executed, and the compiler (cl) launched a warning:
6977 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6979 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6980 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

6987 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6988 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6989 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6990 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6991 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6992 - added Release configuration in VS projects
6993 - review of compiler an linker options
6994 - VC .exe files are generated in bin_vc directory, not to interfere
6995 with binaries generated from other projects (cygwin, mingw, bcc ...)
6997 * sdcc/src/yacc.dsp: added
6999 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7000 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7001 and insert the version number definitions from .version
7003 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7005 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7015 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7017 2002-08-10 Borut Razem <borut.razem AT siol.net>
7018 * src/SDCCmain.c (main):
7019 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7020 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7021 The consequence was that some temporary files were not removed.
7024 unification of code in functions tempfilename() and tempfile():
7025 function tempnam() is defined in Visual Studio 6.0 and .NET
7027 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7029 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7030 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

7045 added return 0 statements after assert() to make compiler happy
7047 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7048 added newline in the def file to keep MSC compiler satisfied
7050 * sdcc/src/z80/gen.c:
7051 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7052 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7053 - solved MSC error in function aopDump()
7055 * sdcc_vc.h: define PREFIX as "\\sdcc"
7057 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7113 were not getting allocated.
7115 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7118 Fixed left shift. Will promote the left side of a left shift
7119 if a) left shifting more than size of operand or b) when assigned
7120 to something size > size of left side
7122 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7232 * sdcc/src/SDCCloop.c:
7233 Previous fix was not good. basic blocks that have "break" or "return" are
7234 not really partof a loop , but live ranges used in these blocks should
7235 be live thru the entire loop, so set partOfLoop but don't add them to
7238 2002-02-21 <johan AT FRIJA>
