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

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

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

3618 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3620 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3621 loaded with the linker search paths (-L arguments) and the libraries
3622 to be linked with the current source (-l arguments). Changes
3623 currently will affect only the pic16 port.
3624 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3625 include path the port specific paths and port specific libraries,
3626 * gplink command now contains the $3 argument,
3627 * src/pic16/device.h,
3628 * src/pic16/device.c,: structure PIC_device is made public and
3629 renamed to PIC16_device, the same for variable Pics which is renamed
3630 to Pics16. Updated all references to them.
3631 * src/pic16/glue.c (pic16glue): corrected bug with code

3642 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3644 Documenting changes from previous commits.
3645 * configure.in (version 1.56),
3646 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3647 when generating output files to configure the pic16 library,
3648 but now I've commented it out, since gputils aren't installed in the
3649 SF compile farm, so library won't compile
3651 * device/lib/Makefile.in (version 1.56): initially I've added in
3652 target 'all' the prerequestive 'model-pic16' so it compiled the
3653 pic16 library, but now I've commented it out for the same reasons
3655 * added targets 'model-pic16' and 'objects-pic16' to compile the
3657 * added target 'port-specific-objects-pic16' to handle the
3658 generated libraries and copy them into the build/ directory
3659 * added target 'clean-intermediate-pic16' to clean intermediate
3660 files into pic16 directory
3661 * in target 'installdirs' added line to create directory pic16 in
3662 the installation path
3664 * device/include/Makefile.in (version 1.11): in target 'install'
3665 added lines to copy all header files to installation path,
3666 * in target 'installdirs' added line create directory for pic16
3667 headers in the installation path

3682 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3683 option so that it actually works. Made it specific to the z80, since
3684 the gbz80 doesn't have these kinds of I/O ports.
3686 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3688 * device/include/z180.h,

3701 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3703 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
3704 changed interrupt vector table generation to only emit declared vectors.
3705 * device/include/Makefile.in: added missing backslash
3706 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
3708 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3710 Mainly changes to support compilation of the device libraries
3711 * src/pic16/device.c: stack is allocated via symbol and not
3712 via literal number. The symbol is placed in the corresponding
3713 position of the data ram
3714 * (pic16_dump_section): relocatable and absolute uninitialized
3715 data are now emitted in sorted order to reduce section naming,
3716 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3717 weren't marked as being in the access bank,
3719 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3721 Added portion of GNU PIC Library under the directory
3722 device/include/pic16 and device/lib/pic16. These files
3723 contain the declarations of SFRs for the PIC18Fxx2 devices.
3724 The directory is initialized via configure from toplevel.
3726 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3728 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
3729 the spilllocations to be compared correctly
3731 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3733 * src/SDCCast.c (decorateType): fixed bug introduced today
3735 2004-01-12 Borut Razem <borut.razem AT siol.net>
3737 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

3740 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
3742 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
3743 in simpler and even better code
3745 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
3747 * src/SDCCicode.c (operandOperation): fixed bug #874819

3753 * doc/sdccman.lyx: Moved and added some sections, small changes
3754 all over. Telling LaTeX to be less strict with word spacing
3755 to better keep the right margin. Changed some notes about
3756 maintainance of the ports in section 3.2.1 - is it OK like this?
3758 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3795 UPPER for immediate operands,
3796 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3798 * src/pic16/peeph.def: all peepholes with movff are commented out,
3799 because there is a problem in the pcode peep optimizer,
3800 * src/pic16/ralloc.c: the register allocator can now reuse local
3801 function symbols for another function. This saves register usage.
3802 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3804 Added file src/pic16/NOTES with information about program writing on
3805 the current port version.

3834 gen51Code): more efficient parameter receive for --model-large
3837 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3840 * src/z80/main.c: added missed needLinkerScript flags (more than
3841 one port structure defined in these file)
3842 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

3858 needLinkerScript flag
3860 * src/pic16/gen.c (genAddrOf): fixed bug #863624
3861 * src/pic/glue.c: added variable udata_section_name to
3862 override default uninitialized data segment definition for
3863 devices only with SHAREBANK memory (reported from Erik Epetrich)
3864 * (pic14emitOverlay): modified to emit a commented overlay segment
3865 directive when no overlay data exist
3866 * (picglue): modified to emit uninitialized data segment
3867 according to udata_section_name

3873 * src/pic16/main.c: added $l in _asmCmd, changed extension for
3874 object file from '.rel' to '.o' in port->linker structure,
3875 changed size of fptr from 2 to 3 in port structure
3877 2004-01-07 Borut Razem <borut.razem AT siol.net>
3879 * support/scripts/sdcc.nsi: update PATH
3880 * support/scripts/sdcc.ico: craeted
3882 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

3893 include information about variables allocated to the overlay
3896 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3898 * as/mcs51/lkmain.c: Help about -Y option

3910 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3912 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3913 (default behaviour).
3915 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3917 A python script to validate compiler diagnostic messages. It can be
3918 used to verify that sdcc complains about bad c source code and
3919 gives a good location of the error.
3920 * support/valdiag/Makefile,
3921 * support/valdiag/valdiag.py,
3922 * support/valdiag/tests/*
3924 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3926 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

3935 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3937 * src/common.h: added ifndef/define/endif macros
3938 around the header file.
3939 Bug reported from Jesus Calvino-Fraga
3941 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3943 * sdcc.spec: updated
3944 * device/include/Makefile.in: don't install CVS directories
3945 * device/lib/Makefile.in: added removal of CVS directories after install
3946 * doc/Makefile: fixed install, added local_icons
3947 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3948 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3949 * src/ds390/gen.c (genRightShift): fixed bug #870788
3950 * src/SDCCast.c (decorateType): fixed bug #870781
3952 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3954 PIC16 port related changes:
3955 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3956 added variable stackPos,
3958 * gen.c: genCall, assignResultValue: added support for
3959 pushing/retrieving function parameters to/from stack,
3960 genFunction,genEndFunction: setup stack frame for the
3962 genAddrOf: will be changed according to bug 863624
3964 * added files genutils.c and genutils.h which contain gen*
3965 debugged and optimised functions extracted from gen.c
3967 * glue.c: added variable 'externs' which holds extern symbols,
3968 pic16emitRegularMap: is modified to properly handle relocatable
3969 symbols under the new scheme,
3970 pic16createInterruptVect: is modified
3971 pic16printPublics: is modified to emit 'global' assembler directives,
3972 added pic16_printExterns to print extern symbols,
3973 pic16glue: initializes stack/frame pointer in the beginning of
3974 the assembly output. Temporary hack, will be corrected later,
3975 because gplink yet does not support stack and SDCC does not
3976 yet support a type of crt0.o object to create the final binary.
3978 * Removed many lines that contain 8051 legacy code.
3979 * The code is finally placed under a 'code' directive.
3980 * Added port specific options.
3982 * _process_pragma: simplified since now we do not need *special*
3983 include file to define SFR registers. But a separate header
3984 will be needed. This will be developed later.
3985 * _pic16_parseOptions: added, parses port specific options:
3986 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3987 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3988 --preplace-udata-with=
3990 * _pic16_setDefaultOptions: modified to initialize section names,
3991 but hack is temporarly out of order since it needs improvement.
3992 * _pic16_genAssemblerPreamble: configuration words are emitted by
3993 their address instead of their name. This part is incomplete and
3994 supports only the 18Fxx2 devices. Other devices will emit an error
3995 during assembly since they do not contain the same set of config
3997 * _pic16_genIVT: is modified,
3999 * pcode.c: added definitions for some hardware registers that are needed
4001 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4002 All PCI entries are updated. Now LFSR is supported.
4003 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4004 * added pic16_newpCodeOpLit2 to support instructions with
4005 two literal arguments
4006 * pic16_pCode2str: corrected code that emits assembler instructions
4007 with two literal operands and those that have an access bit modifier
4008 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4009 this fixes a bug which caused some labels to be lost, when an
4010 assembler directive was added, i.e. banksel,
4011 * pic16_FixRegisterBanking: improved logic that causes the insertion
4013 * InlineFunction: functions that are called once, are not any more
4014 inlined. This can be a port option in the future,
4016 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4018 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4019 hold the corresponding uninitialized symbols,
4020 * pic16_allocProcessorRegister: registers have explicit marked the
4022 * pic16_allocInternalRegister: registers are explicit marked as
4024 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4025 processing list, so bit registers were lost,
4028 * ralloc.h: added field 'accessBank' and original symbol operand
4029 in register definition,
4030 * removed the field isMapped from register definition,
4032 ** Several functions have been removed from various sources:
4033 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4034 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4035 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4036 pic16_assignRelocatableRegisters
4038 ** others have been introduced:
4039 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4040 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4042 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4044 * support/scripts/inc2h.pl: changed definition of BIT_AT
4045 to emit 'sbit at' instead of 'bit at'. This was a request.
4047 PIC16 port related preliminary changes:
4048 * gen.c: prefixed function popRegFromString with
4049 pic16_ and all references to it corrected
4050 * pcode.c: all pic16_pc_* hardware registers prefixed
4051 with underscore (_),
4052 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4053 * ralloc.c: newReg(): when register is REG_SFR then
4054 set address to rIdx,
4055 pic16_allocProcessorRegister(): marks register wasUsed=0
4056 pic16_writeUsedRegs(): added a call to assign processor
4057 registers via pic16_assignFixedRegisters
4059 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4061 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4062 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4063 variables in unused register banks. Also the SSEG is placed
4064 wherever there is enough space for it, and IDATA can be anywhere
4065 in internal RAM. For now compile using -Wl-Y[stack_size].
4066 The mem file is different for this option as well, since it
4067 makes no sense of talking about DSEG lenght.

5062 and JUMPTABLE iCodes properly now (worked by accident before)
5063 * src/mcs51/gen.c (leftRightUseAcc),
5064 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5065 iCode properly now. Use getSize instead of nRegs since a & b
5066 aren't part of the nRegs tally.
5068 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5070 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
5071 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5072 before instructions that use the _STATUS register
5074 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5076 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5077 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5078 fetching of the pointer
5079 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5080 copied from genNearPointerSet()
5081 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5082 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5083 If they pop r0/r1 they must be called in the opposite order than aopOp().
5084 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5085 (resp. --stack-auto), prepared for --xstack
5087 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5091 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5093 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
5094 these ports have their own __sdcc_external_start()
5096 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5098 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5099 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5100 type for bits was changed. It resulted in bit variables becoming
5101 global, which is not permitted in PIC 14 assembly output.
5103 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5105 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5107 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5109 Z80 and MCS51 linkers complaint if a public symbol is defined
5110 in more than one library module:

5116 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5118 A few small changes that speed up the peephole optimizer.
5122 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5124 Try to make the peephole optimizer smarter by maintaining
5125 an association between the assembly source code and the
5126 iCodes that originated them. Put this information to use
5127 with a new peephole rule condition "notVolatile" so that
5128 the rules can be aggressive yet still safe.
5133 * src/mcs51/peeph.def
5135 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5139 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5140 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5141 if the left or right operand symbols have the accuse flag set.
5143 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5145 Changed the type of the result of the ! (NOT) operator to char;
5146 previously it returned the same type as the source. This allows
5147 us to eliminate all the genFloatNot functions (all of its target
5148 implementations were very buggy) since !float can use the same
5151 * src/SDCCicode.c (ast2iCode): ! returns char
5152 * src/mcs51/gen.c (genNot, genNotFloat),
5153 * src/ds390/gen.c (genNot, genNotFloat),
5154 * src/z80/gen.c (genNot, genNotFloat),
5155 * src/pic/gen.c (genNot, genNotFloat),
5156 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5158 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5160 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5161 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5162 during interrupts. Ensure WSAVE is located at a shared bank address.
5163 2. Fixed page selection in some places
5164 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5165 the registers name strings.
5166 4. Fixed "signed / unsigned compare" compiler warnings.
5167 5. The PIC port manages its own allocation of the general purpose
5168 registers, but makes no attempt to reuse them. As a result when
5169 compiling it soon runs out of general purpose registers. Some
5170 additional code was added to the files pcode.c and device.c to walk
5171 through the function call tree and rename the registers so that they
5181 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5182 genPlus() & genMinus() when the result is the same as left or right

5188 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5190 Made bitfield a distinct type from bit so that bitfields
5191 convert as per ANSI C and bits retain their traditional
5192 boolean style behaviour. Implemented bitfield support in
5200 * src/ds390/gen.c: bit v bitfield split
5201 * src/z80/gen.c: New support for bitfields
5202 * support/regression/tests/bitfields.c: reenabled z80,
5205 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5207 Rules 246.x, 247.x relate to bitfields, the others speed up
5208 access to xdata mapped I/O devices.
5210 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5212 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5214 Cleaned up genPackBits and genUnpackBits and added two helper
5215 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5216 for literal assignments in genPackBits (thanks to Frieder for
5222 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5224 Fixed bug #748310 (pointer to function type mishandled when the
5225 function name is omitted). Also fixed a SIGSEGV when a function
5226 attribute (reentrant, etc) is used on a non-function or on a
5227 function but misplaced before the parameter list.
5229 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5231 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5232 * support/Util/SDCCerr.h,
5233 * support/Util/SDCCerr.c: Added func attr misuse error msg

5254 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5256 Made the constant following the "interrupt" keyword optional. If
5257 omitted, the function will not automatically be given an entry
5258 in the interrupt vector table (similar to #pragma NOIV, but
5259 less syntacticly kludgy). The interrupt number is also now
5260 range checked. Also fixed a bug in the high order bit example
5267 * support/Util/SDCCerr.c
5268 * support/Util/SDCCerr.h
5271 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5274 * src/SDCCicode.c (operandOperation): rewritten some ops
5275 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5276 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5278 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5279 be re-activated by defining REDUCE_LITERALS)
5280 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5281 unsigned, but are signed by default
5282 * src/SDCCval.c (constVal): rearranged
5283 * src/SDCCval.c (valMod): preliminary fix
5284 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5327 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5328 * src/SDCCval.c (valDiv, valMod): fixed signdness
5329 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5330 signedness of modulo, left and right shift

5736 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5737 the regression tests I'm not brave enough to enable 245.b, 245.c
5738 * doc/sdccman.lyx: added latex preamble for hyperref package.
5739 Using pdflatex this will give you a hyperlinked pdf file with
5740 bookmarks. (prepend '%' before /usepackage if this breaks something)

5781 it can be defined with CFLAGS when running configure
5782 * src/SDCCmain.c: fixed compiling + linking with object files
5784 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5789 * src/SDCCmain.c: linkOptions is changed to set *,
5790 added if/endif conditional macros to remove options help
5791 messages from optionsTable when a port is not configured, added
5792 support for the PIc16 port in the ports table, when executing
5793 the compiler with no port specified on command line, a default
5794 port is selected with the new macro DEFAULT_PORT which is
5795 defined in port.h, in setDefaultOptions() linkOptions is removed
5796 from initialization assignment, since now it is a set,
5797 parseCmdLine uses setParseWithComma for linkOptions, in
5798 linkEdit() linkOptions are accessed with new function indexSet()
5799 which returns the i'th item of a set variable. See SDCCset.c, in
5800 linkEdit() when calling buildCmdLine(), added linkOptions as
5801 last argument. Now users can pass arguments to gplink via the
5802 -Wl option, main() uses pic16glue() to glue up pic16 programs

5814 * src/pic16/glue.c: commented out some error producing lines
5815 * src/pic16/main.c: __config directives are commented out to stop
5816 gpasm complaining and test the linkage with gplink, _linkCmd and
5817 _asmCmd changed to be more gplink and gpasm friendly
5818 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5819 produced an error when parsed, peep rule 12 is added to utilize
5820 movff, but it is commented out since the pCode does not support
5821 yet a command with 2 address arguments
5823 2003-05-18 <johan AT balder>
5825 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5826 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5850 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
5852 2003-05-11 Borut Razem <borut.razem AT siol.net>
5854 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5855 the path of bin directory, so that PATH is the only env. variable, which has to be set
5856 in case of standard installation.
5857 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6886 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6888 * in \sdcc\as\mcs51\ changed these files in order to create an
6889 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6890 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6891 following files to include the previous two files: aslink.dsp,
6892 Makefile.aslink, Makefile.bcc, and Makefile.in.
6894 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6895 .adb instead of .cdb
6897 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6899 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6900 value from option --iram-size.
6902 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6904 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6907 2002-09-18 <wiml AT hhhh.org>
6909 * SDCClrange.h: exposed setFromRange() and setToRange()
6910 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6911 packRegsForAccUse() (bug 542397)
6912 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6913 multiple times and emitting the fetch operations more than once
6914 added aopGetUsesAcc() function to allow binary operators to
6915 fetch their operands in the correct order; made genMinus() emit
6916 compact code for X = LITERAL - Y
6918 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6919 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6920 sprintf() in line 1267.
6922 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6923 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6926 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6927 Changes to aslink (All the changes are marked with 'JCF'):
6929 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6932 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6933 area BSEG. Also moves, if possible, the DATA area down into the internal
6934 ram so more space is available.
6936 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6939 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6940 not bytes. Function summary() which creates a memory usage summary
6941 file with extension .mem. Reports of overlaping stack and small stack
6942 size. If the space for the stack is less than 16 bytes aslink trows a
6945 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6946 the 8051. Option 'y' for memory summary output file.
6948 Changes to sdcc (All the changes are marked with 'JCF'):
6950 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6952 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6953 overlaying area for it (uses RegBankUsed[4]).
6955 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6956 bank zero as used by default. By default aslink locates the stack
6957 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6958 the creation of the .mem file. Delegates the allocation of data area
6959 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6960 the begining of the stack area to aslink.
6962 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6963 glue() in SDCCglue.c creates an area for it.
6965 2002-09-03 Borut Razem <borut.razem AT siol.net>
6966 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6967 sdcc/src/pic/glue.c:
6968 introduced atexit() handler for teporay files removal in case of
6969 errors, assertions, ...
6971 2002-08-29 Borut Razem <borut.razem AT siol.net>
6972 * sdcc/support/cpp2/auto-host_vc_in.h:
6973 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6974 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6975 Maybe there is a similar problem with BORLANDC? It should be checked!
6977 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6978 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6979 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6980 was not executed, and the compiler (cl) launched a warning:
6981 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6983 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

6990 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6991 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6992 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6993 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6994 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6995 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6996 - added Release configuration in VS projects
6997 - review of compiler an linker options
6998 - VC .exe files are generated in bin_vc directory, not to interfere
6999 with binaries generated from other projects (cygwin, mingw, bcc ...)
7001 * sdcc/src/yacc.dsp: added
7003 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7004 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7005 and insert the version number definitions from .version
7007 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7009 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7019 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7021 2002-08-10 Borut Razem <borut.razem AT siol.net>
7022 * src/SDCCmain.c (main):
7023 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7024 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7025 The consequence was that some temporary files were not removed.
7028 unification of code in functions tempfilename() and tempfile():
7029 function tempnam() is defined in Visual Studio 6.0 and .NET
7031 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7033 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7034 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

7048 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7049 added return 0 statements after assert() to make compiler happy
7051 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7052 added newline in the def file to keep MSC compiler satisfied
7054 * sdcc/src/z80/gen.c:
7055 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7056 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7057 - solved MSC error in function aopDump()
7059 * sdcc_vc.h: define PREFIX as "\\sdcc"
7061 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7117 were not getting allocated.
7119 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7122 Fixed left shift. Will promote the left side of a left shift
7123 if a) left shifting more than size of operand or b) when assigned
7124 to something size > size of left side
7126 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7234 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7236 * sdcc/src/SDCCloop.c:
7237 Previous fix was not good. basic blocks that have "break" or "return" are
7238 not really partof a loop , but live ranges used in these blocks should
7239 be live thru the entire loop, so set partOfLoop but don't add them to
7242 2002-02-21 <johan AT FRIJA>
7244 * src/SDCCcse.c: fixed bug #514308
7246 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
