554 Adding support for replacing ljmps with sjmps in jumptables
555 generated for switch statements. For now you need to set the
556 environment variable SDCC_SJMP_JUMPTABLE to enable this.
557 Now 4 algorithms for mcs51 jumptable generation are used:
558 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
559 addresses loaded pc-relative for up to 112 cases and stack-pushing
560 target addresses loaded with offset from dptr for up to 256 cases.

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

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

3571 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3573 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
3575 * src/pic/pcode.c (PCodeID): commented out left over debug code
3577 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
3579 * support/valdiag/tests/overflow.c: added shift tests
3587 * src/pic/pcodepeep.c,
3588 * src/pic/pcoderegs.c,
3590 * src/pic/ralloc.h: applied patch from Slade Rich;
3591 added support for multiple code pages and multiple RAM banks on the
3592 PIC 14 port. The ASM files now no longer simply assume all the
3593 code / RAM are in the same page / bank. This means the linker can
3594 safely allocate code/RAM of separate ASM files to different pages/banks.
3595 * doc/sdccman.lyx: added Slade's tips
3596 * src/mcs51/peeph.def: fixed bug #880768

3605 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3608 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3609 strtof is not part of C89 and isn't included with Mac OS X.
3611 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3613 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3622 2004-01-19 Bernhard Held <bernhard AT bernhardheld.de>
3624 * src/SDCCicode.c (geniCodeArray): applied patch from Stas Sergeev
3625 proposed in FR #877103
3627 2004-01-18 Bernhard Held <bernhard AT bernhardheld.de>
3629 * src/SDCCval.c (cheapestVal): added missing checks
3630 * src/SDCCicode.c (usualBinaryConversions): fixed condition
3631 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
3633 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>

3638 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3640 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3641 loaded with the linker search paths (-L arguments) and the libraries
3642 to be linked with the current source (-l arguments). Changes
3643 currently will affect only the pic16 port.
3644 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3645 include path the port specific paths and port specific libraries,
3646 * gplink command now contains the $3 argument,
3647 * src/pic16/device.h,
3648 * src/pic16/device.c,: structure PIC_device is made public and
3649 renamed to PIC16_device, the same for variable Pics which is renamed
3650 to Pics16. Updated all references to them.
3651 * src/pic16/glue.c (pic16glue): corrected bug with code
3652 initialization which bypassed the variable initializations block.
3654 * device/lib/pic16/Makefile.rules: removed --penable-stack from
3655 COMPILE_FLAGS and added the --nostdinc option
3657 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3659 * device/include/mc68hc908jb8.h: Register defs for another member

3662 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3664 Documenting changes from previous commits.
3665 * configure.in (version 1.56),
3666 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3667 when generating output files to configure the pic16 library,
3668 but now I've commented it out, since gputils aren't installed in the
3669 SF compile farm, so library won't compile
3671 * device/lib/Makefile.in (version 1.56): initially I've added in
3672 target 'all' the prerequestive 'model-pic16' so it compiled the
3673 pic16 library, but now I've commented it out for the same reasons
3675 * added targets 'model-pic16' and 'objects-pic16' to compile the
3677 * added target 'port-specific-objects-pic16' to handle the
3678 generated libraries and copy them into the build/ directory
3679 * added target 'clean-intermediate-pic16' to clean intermediate
3680 files into pic16 directory
3681 * in target 'installdirs' added line to create directory pic16 in
3682 the installation path
3684 * device/include/Makefile.in (version 1.11): in target 'install'
3685 added lines to copy all header files to installation path,
3686 * in target 'installdirs' added line create directory for pic16
3687 headers in the installation path

3702 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3703 option so that it actually works. Made it specific to the z80, since
3704 the gbz80 doesn't have these kinds of I/O ports.
3706 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3708 * device/include/z180.h,

3730 Mainly changes to support compilation of the device libraries
3731 * src/pic16/device.c: stack is allocated via symbol and not
3732 via literal number. The symbol is placed in the corresponding
3733 position of the data ram
3734 * (pic16_dump_section): relocatable and absolute uninitialized
3735 data are now emitted in sorted order to reduce section naming,
3736 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3737 weren't marked as being in the access bank,
3739 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3741 Added portion of GNU PIC Library under the directory
3742 device/include/pic16 and device/lib/pic16. These files
3743 contain the declarations of SFRs for the PIC18Fxx2 devices.
3744 The directory is initialized via configure from toplevel.
3746 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3748 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3774 all over. Telling LaTeX to be less strict with word spacing
3775 to better keep the right margin. Changed some notes about
3776 maintainance of the ports in section 3.2.1 - is it OK like this?
3778 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3816 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3818 * src/pic16/peeph.def: all peepholes with movff are commented out,
3819 because there is a problem in the pcode peep optimizer,
3820 * src/pic16/ralloc.c: the register allocator can now reuse local

3882 override default uninitialized data segment definition for
3883 devices only with SHAREBANK memory (reported from Erik Epetrich)
3884 * (pic14emitOverlay): modified to emit a commented overlay segment
3885 directive when no overlay data exist
3886 * (picglue): modified to emit uninitialized data segment
3887 according to udata_section_name

3940 * support/valdiag/Makefile,
3941 * support/valdiag/valdiag.py,
3942 * support/valdiag/tests/*

3959 Bug reported from Jesus Calvino-Fraga
3961 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3963 * sdcc.spec: updated
3964 * device/include/Makefile.in: don't install CVS directories

3972 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3974 PIC16 port related changes:
3975 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3976 added variable stackPos,
3978 * gen.c: genCall, assignResultValue: added support for
3979 pushing/retrieving function parameters to/from stack,
3980 genFunction,genEndFunction: setup stack frame for the
3982 genAddrOf: will be changed according to bug 863624
3984 * added files genutils.c and genutils.h which contain gen*
3985 debugged and optimised functions extracted from gen.c
3987 * glue.c: added variable 'externs' which holds extern symbols,
3988 pic16emitRegularMap: is modified to properly handle relocatable
3989 symbols under the new scheme,
3990 pic16createInterruptVect: is modified
3991 pic16printPublics: is modified to emit 'global' assembler directives,
3992 added pic16_printExterns to print extern symbols,
3993 pic16glue: initializes stack/frame pointer in the beginning of
3994 the assembly output. Temporary hack, will be corrected later,
3995 because gplink yet does not support stack and SDCC does not
3996 yet support a type of crt0.o object to create the final binary.
3998 * Removed many lines that contain 8051 legacy code.
3999 * The code is finally placed under a 'code' directive.
4000 * Added port specific options.
4002 * _process_pragma: simplified since now we do not need *special*
4003 include file to define SFR registers. But a separate header
4004 will be needed. This will be developed later.
4005 * _pic16_parseOptions: added, parses port specific options:
4006 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4007 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4008 --preplace-udata-with=
4010 * _pic16_setDefaultOptions: modified to initialize section names,
4011 but hack is temporarly out of order since it needs improvement.
4012 * _pic16_genAssemblerPreamble: configuration words are emitted by
4013 their address instead of their name. This part is incomplete and
4014 supports only the 18Fxx2 devices. Other devices will emit an error
4015 during assembly since they do not contain the same set of config
4017 * _pic16_genIVT: is modified,
4019 * pcode.c: added definitions for some hardware registers that are needed
4021 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4022 All PCI entries are updated. Now LFSR is supported.
4023 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4024 * added pic16_newpCodeOpLit2 to support instructions with
4025 two literal arguments
4026 * pic16_pCode2str: corrected code that emits assembler instructions
4027 with two literal operands and those that have an access bit modifier
4028 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4029 this fixes a bug which caused some labels to be lost, when an
4030 assembler directive was added, i.e. banksel,
4031 * pic16_FixRegisterBanking: improved logic that causes the insertion
4033 * InlineFunction: functions that are called once, are not any more
4034 inlined. This can be a port option in the future,
4036 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4038 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4039 hold the corresponding uninitialized symbols,
4040 * pic16_allocProcessorRegister: registers have explicit marked the
4042 * pic16_allocInternalRegister: registers are explicit marked as
4044 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4045 processing list, so bit registers were lost,
4048 * ralloc.h: added field 'accessBank' and original symbol operand
4049 in register definition,
4050 * removed the field isMapped from register definition,
4052 ** Several functions have been removed from various sources:
4053 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4054 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4055 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4056 pic16_assignRelocatableRegisters
4058 ** others have been introduced:
4059 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4060 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4062 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4064 * support/scripts/inc2h.pl: changed definition of BIT_AT
4065 to emit 'sbit at' instead of 'bit at'. This was a request.
4067 PIC16 port related preliminary changes:
4068 * gen.c: prefixed function popRegFromString with
4069 pic16_ and all references to it corrected
4070 * pcode.c: all pic16_pc_* hardware registers prefixed
4071 with underscore (_),
4072 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4073 * ralloc.c: newReg(): when register is REG_SFR then
4074 set address to rIdx,
4075 pic16_allocProcessorRegister(): marks register wasUsed=0
4076 pic16_writeUsedRegs(): added a call to assign processor
4077 registers via pic16_assignFixedRegisters
4079 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4081 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4082 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4083 variables in unused register banks. Also the SSEG is placed
4084 wherever there is enough space for it, and IDATA can be anywhere
4085 in internal RAM. For now compile using -Wl-Y[stack_size].
4086 The mem file is different for this option as well, since it
4087 makes no sense of talking about DSEG lenght.
4089 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4091 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4336 * src/SDCCast.c (decorateType): disabled a transformation I added in
4337 revision 1.188 (access to fields of a structure at an absolute address);
4338 it breaks with bitfields, extern declarations, and gcse analysis.
4339 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4340 could be assigned through a pointer, so don't complain.

5064 reported in bug #800609
5066 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
5068 * Top header beautifications in src/pic16 directory:
5069 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
5070 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
5071 pcoderegs.h, ralloc.c, ralloc.h
5072 * main.c: added top header and GPL license notice
5073 * pcode.c: fixed the if-conditional warning
5075 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
5077 * device/lib/_mullong.c: replaced int by short for gcc
5079 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5081 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
5082 and JUMPTABLE iCodes properly now (worked by accident before)
5083 * src/mcs51/gen.c (leftRightUseAcc),
5084 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5085 iCode properly now. Use getSize instead of nRegs since a & b
5086 aren't part of the nRegs tally.
5088 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5090 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
5091 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
5092 before instructions that use the _STATUS register
5094 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
5096 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5097 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5098 fetching of the pointer
5099 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5100 copied from genNearPointerSet()
5101 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5102 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5103 If they pop r0/r1 they must be called in the opposite order than aopOp().
5104 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5105 (resp. --stack-auto), prepared for --xstack
5107 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5114 these ports have their own __sdcc_external_start()
5116 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5118 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5119 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5120 type for bits was changed. It resulted in bit variables becoming
5121 global, which is not permitted in PIC 14 assembly output.
5123 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5125 * doc/sdccman.lyx: various additions and updates. Rearranged sections
5127 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5129 Z80 and MCS51 linkers complaint if a public symbol is defined
5130 in more than one library module:
5134 * as/mcs51/Makefile.in
5136 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5138 A few small changes that speed up the peephole optimizer.
5142 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5144 Try to make the peephole optimizer smarter by maintaining
5145 an association between the assembly source code and the
5146 iCodes that originated them. Put this information to use
5147 with a new peephole rule condition "notVolatile" so that
5148 the rules can be aggressive yet still safe.
5153 * src/mcs51/peeph.def
5155 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5159 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5160 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5161 if the left or right operand symbols have the accuse flag set.
5163 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5165 Changed the type of the result of the ! (NOT) operator to char;
5166 previously it returned the same type as the source. This allows
5167 us to eliminate all the genFloatNot functions (all of its target
5168 implementations were very buggy) since !float can use the same
5171 * src/SDCCicode.c (ast2iCode): ! returns char
5172 * src/mcs51/gen.c (genNot, genNotFloat),
5173 * src/ds390/gen.c (genNot, genNotFloat),
5174 * src/z80/gen.c (genNot, genNotFloat),
5175 * src/pic/gen.c (genNot, genNotFloat),
5176 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5178 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5180 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5181 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5182 during interrupts. Ensure WSAVE is located at a shared bank address.
5183 2. Fixed page selection in some places
5184 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5185 the registers name strings.
5186 4. Fixed "signed / unsigned compare" compiler warnings.
5187 5. The PIC port manages its own allocation of the general purpose
5188 registers, but makes no attempt to reuse them. As a result when
5189 compiling it soon runs out of general purpose registers. Some
5190 additional code was added to the files pcode.c and device.c to walk
5191 through the function call tree and rename the registers so that they
5201 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5202 genPlus() & genMinus() when the result is the same as left or right

5208 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5210 Made bitfield a distinct type from bit so that bitfields
5211 convert as per ANSI C and bits retain their traditional
5212 boolean style behaviour. Implemented bitfield support in
5220 * src/ds390/gen.c: bit v bitfield split
5221 * src/z80/gen.c: New support for bitfields
5222 * support/regression/tests/bitfields.c: reenabled z80,
5225 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5227 Rules 246.x, 247.x relate to bitfields, the others speed up
5228 access to xdata mapped I/O devices.
5230 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5232 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5234 Cleaned up genPackBits and genUnpackBits and added two helper
5235 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5236 for literal assignments in genPackBits (thanks to Frieder for
5242 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5244 Fixed bug #748310 (pointer to function type mishandled when the
5245 function name is omitted). Also fixed a SIGSEGV when a function
5246 attribute (reentrant, etc) is used on a non-function or on a
5247 function but misplaced before the parameter list.
5249 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5251 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5252 * support/Util/SDCCerr.h,
5253 * support/Util/SDCCerr.c: Added func attr misuse error msg
5255 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5257 Fixed bug #787649 by anonymous
5258 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

5274 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5276 Made the constant following the "interrupt" keyword optional. If
5277 omitted, the function will not automatically be given an entry
5278 in the interrupt vector table (similar to #pragma NOIV, but
5279 less syntacticly kludgy). The interrupt number is also now
5280 range checked. Also fixed a bug in the high order bit example
5287 * support/Util/SDCCerr.c
5288 * support/Util/SDCCerr.h
5291 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5294 * src/SDCCicode.c (operandOperation): rewritten some ops
5295 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5296 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5298 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5299 be re-activated by defining REDUCE_LITERALS)
5300 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5301 unsigned, but are signed by default
5302 * src/SDCCval.c (constVal): rearranged
5303 * src/SDCCval.c (valMod): preliminary fix
5304 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5347 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5348 * src/SDCCval.c (valDiv, valMod): fixed signdness
5349 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5350 signedness of modulo, left and right shift

5756 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5757 the regression tests I'm not brave enough to enable 245.b, 245.c
5758 * doc/sdccman.lyx: added latex preamble for hyperref package.
5759 Using pdflatex this will give you a hyperlinked pdf file with
5760 bookmarks. (prepend '%' before /usepackage if this breaks something)

5798 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5800 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5801 it can be defined with CFLAGS when running configure
5802 * src/SDCCmain.c: fixed compiling + linking with object files
5804 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5807 added --disable-pic16-port
5808 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5809 * src/SDCCmain.c: linkOptions is changed to set *,
5810 added if/endif conditional macros to remove options help
5811 messages from optionsTable when a port is not configured, added
5812 support for the PIc16 port in the ports table, when executing
5813 the compiler with no port specified on command line, a default
5814 port is selected with the new macro DEFAULT_PORT which is
5815 defined in port.h, in setDefaultOptions() linkOptions is removed
5816 from initialization assignment, since now it is a set,
5817 parseCmdLine uses setParseWithComma for linkOptions, in
5818 linkEdit() linkOptions are accessed with new function indexSet()
5819 which returns the i'th item of a set variable. See SDCCset.c, in
5820 linkEdit() when calling buildCmdLine(), added linkOptions as
5821 last argument. Now users can pass arguments to gplink via the
5822 -Wl option, main() uses pic16glue() to glue up pic16 programs

5834 * src/pic16/glue.c: commented out some error producing lines
5835 * src/pic16/main.c: __config directives are commented out to stop
5836 gpasm complaining and test the linkage with gplink, _linkCmd and
5837 _asmCmd changed to be more gplink and gpasm friendly
5838 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5839 produced an error when parsed, peep rule 12 is added to utilize
5840 movff, but it is commented out since the pCode does not support
5841 yet a command with 2 address arguments
5843 2003-05-18 <johan AT balder>
5845 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5846 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5872 2003-05-11 Borut Razem <borut.razem AT siol.net>
5874 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5875 the path of bin directory, so that PATH is the only env. variable, which has to be set
5876 in case of standard installation.
5877 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6909 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6910 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6911 following files to include the previous two files: aslink.dsp,
6912 Makefile.aslink, Makefile.bcc, and Makefile.in.
6914 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6915 .adb instead of .cdb
6917 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6919 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6920 value from option --iram-size.
6922 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6924 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6927 2002-09-18 <wiml AT hhhh.org>
6929 * SDCClrange.h: exposed setFromRange() and setToRange()
6930 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6931 packRegsForAccUse() (bug 542397)
6932 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6933 multiple times and emitting the fetch operations more than once
6934 added aopGetUsesAcc() function to allow binary operators to
6935 fetch their operands in the correct order; made genMinus() emit
6936 compact code for X = LITERAL - Y
6938 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6939 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6940 sprintf() in line 1267.
6942 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6946 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6947 Changes to aslink (All the changes are marked with 'JCF'):
6949 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6952 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6953 area BSEG. Also moves, if possible, the DATA area down into the internal
6954 ram so more space is available.
6956 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6959 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6960 not bytes. Function summary() which creates a memory usage summary
6961 file with extension .mem. Reports of overlaping stack and small stack
6962 size. If the space for the stack is less than 16 bytes aslink trows a
6965 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6966 the 8051. Option 'y' for memory summary output file.
6968 Changes to sdcc (All the changes are marked with 'JCF'):
6970 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6972 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6973 overlaying area for it (uses RegBankUsed[4]).
6975 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6976 bank zero as used by default. By default aslink locates the stack
6977 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6978 the creation of the .mem file. Delegates the allocation of data area
6979 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6980 the begining of the stack area to aslink.
6982 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6983 glue() in SDCCglue.c creates an area for it.

6986 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6987 sdcc/src/pic/glue.c:
6988 introduced atexit() handler for teporay files removal in case of
6989 errors, assertions, ...
6991 2002-08-29 Borut Razem <borut.razem AT siol.net>
6992 * sdcc/support/cpp2/auto-host_vc_in.h:
6993 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6994 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6995 Maybe there is a similar problem with BORLANDC? It should be checked!
6997 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6998 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6999 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7000 was not executed, and the compiler (cl) launched a warning:
7001 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7003 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7004 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7006 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7007 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7009 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7010 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7011 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7012 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7013 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7014 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7015 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7016 - added Release configuration in VS projects
7017 - review of compiler an linker options
7018 - VC .exe files are generated in bin_vc directory, not to interfere
7019 with binaries generated from other projects (cygwin, mingw, bcc ...)
7021 * sdcc/src/yacc.dsp: added
7023 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7024 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7025 and insert the version number definitions from .version
7027 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7029 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7030 added - genarate auto-host.h using auto-host_vc_in.h as template
7033 removed from CVS, generated automatically
7035 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7036 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7038 2002-08-11 Borut Razem <borut.razem AT siol.net>
7039 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7041 2002-08-10 Borut Razem <borut.razem AT siol.net>
7042 * src/SDCCmain.c (main):
7043 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7044 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7045 The consequence was that some temporary files were not removed.
7048 unification of code in functions tempfilename() and tempfile():
7049 function tempnam() is defined in Visual Studio 6.0 and .NET
7051 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7053 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7054 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7055 - removed compiler command line option /WX: Treats all warnings as errors
7056 - update a list of source files, included into the project
7058 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7059 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7060 changed project type to Generic Project so that can be correcly converted to VS.NET project
7062 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7064 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7066 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7068 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7069 added return 0 statements after assert() to make compiler happy
7071 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7072 added newline in the def file to keep MSC compiler satisfied
7074 * sdcc/src/z80/gen.c:
7075 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7076 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7077 - solved MSC error in function aopDump()
7079 * sdcc_vc.h: define PREFIX as "\\sdcc"
7081 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7082 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7130 Added -p option. Allows port dependent processor to be specified.
7133 Initialized the new field char *Processor field to NULL in all ports
7136 Compiler generated registers for interrupt context saving
7137 were not getting allocated.
7139 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7142 Fixed left shift. Will promote the left side of a left shift
7143 if a) left shifting more than size of operand or b) when assigned
7144 to something size > size of left side
7146 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7256 * sdcc/src/SDCCloop.c:
7257 Previous fix was not good. basic blocks that have "break" or "return" are
7258 not really partof a loop , but live ranges used in these blocks should
7259 be live thru the entire loop, so set partOfLoop but don't add them to
7262 2002-02-21 <johan AT FRIJA>
7264 * src/SDCCcse.c: fixed bug #514308
7266 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
