599 * (malloc.h): added CVS Id tag,
600 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
602 * added libc directory. The current version of LibC contains string
603 functions, ctype functions and macros and some functions of the
604 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
605 be extensively tested in the future. Standard disclaimer here.
606 Library is not automatically build yet. But one can build it by
607 invoking 'make' inside the libc directory.

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

3573 (valBitwise): fixed bug #882876
3574 (valMinus): added promotion
3575 (valLogicAndOr): result is unsigned
3576 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3577 * src/SDCCsymt.c (computeType),
3578 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3579 must not cause an unsigned operation
3580 * src/pic/glue (pic14emitRegularMap),
3581 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3583 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
3585 * src/pic/pcode.c (PCodeID): commented out left over debug code
3587 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
3589 * support/valdiag/tests/overflow.c: added shift tests
3597 * src/pic/pcodepeep.c,
3598 * src/pic/pcoderegs.c,
3600 * src/pic/ralloc.h: applied patch from Slade Rich;
3601 added support for multiple code pages and multiple RAM banks on the
3602 PIC 14 port. The ASM files now no longer simply assume all the
3603 code / RAM are in the same page / bank. This means the linker can
3604 safely allocate code/RAM of separate ASM files to different pages/banks.
3605 * doc/sdccman.lyx: added Slade's tips
3606 * src/mcs51/peeph.def: fixed bug #880768

3615 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3618 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3619 strtof is not part of C89 and isn't included with Mac OS X.
3621 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3648 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3650 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3651 loaded with the linker search paths (-L arguments) and the libraries
3652 to be linked with the current source (-l arguments). Changes
3653 currently will affect only the pic16 port.
3654 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3655 include path the port specific paths and port specific libraries,
3656 * gplink command now contains the $3 argument,
3657 * src/pic16/device.h,
3658 * src/pic16/device.c,: structure PIC_device is made public and
3659 renamed to PIC16_device, the same for variable Pics which is renamed

3672 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
3674 Documenting changes from previous commits.
3675 * configure.in (version 1.56),
3676 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3677 when generating output files to configure the pic16 library,
3678 but now I've commented it out, since gputils aren't installed in the
3679 SF compile farm, so library won't compile
3681 * device/lib/Makefile.in (version 1.56): initially I've added in
3682 target 'all' the prerequestive 'model-pic16' so it compiled the
3683 pic16 library, but now I've commented it out for the same reasons
3685 * added targets 'model-pic16' and 'objects-pic16' to compile the
3687 * added target 'port-specific-objects-pic16' to handle the
3688 generated libraries and copy them into the build/ directory
3689 * added target 'clean-intermediate-pic16' to clean intermediate
3690 files into pic16 directory
3691 * in target 'installdirs' added line to create directory pic16 in
3692 the installation path
3694 * device/include/Makefile.in (version 1.11): in target 'install'
3695 added lines to copy all header files to installation path,
3696 * in target 'installdirs' added line create directory for pic16
3697 headers in the installation path

3712 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3713 option so that it actually works. Made it specific to the z80, since
3714 the gbz80 doesn't have these kinds of I/O ports.
3716 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3718 * device/include/z180.h,

3740 Mainly changes to support compilation of the device libraries
3741 * src/pic16/device.c: stack is allocated via symbol and not
3742 via literal number. The symbol is placed in the corresponding
3743 position of the data ram
3744 * (pic16_dump_section): relocatable and absolute uninitialized
3745 data are now emitted in sorted order to reduce section naming,
3746 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3747 weren't marked as being in the access bank,
3749 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3751 Added portion of GNU PIC Library under the directory
3752 device/include/pic16 and device/lib/pic16. These files
3753 contain the declarations of SFRs for the PIC18Fxx2 devices.
3754 The directory is initialized via configure from toplevel.
3756 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3758 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3784 all over. Telling LaTeX to be less strict with word spacing
3785 to better keep the right margin. Changed some notes about
3786 maintainance of the ports in section 3.2.1 - is it OK like this?
3788 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3826 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3828 * src/pic16/peeph.def: all peepholes with movff are commented out,
3829 because there is a problem in the pcode peep optimizer,
3830 * src/pic16/ralloc.c: the register allocator can now reuse local

3982 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3984 PIC16 port related changes:
3985 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3986 added variable stackPos,
3988 * gen.c: genCall, assignResultValue: added support for
3989 pushing/retrieving function parameters to/from stack,
3990 genFunction,genEndFunction: setup stack frame for the
3992 genAddrOf: will be changed according to bug 863624
3994 * added files genutils.c and genutils.h which contain gen*
3995 debugged and optimised functions extracted from gen.c
3997 * glue.c: added variable 'externs' which holds extern symbols,
3998 pic16emitRegularMap: is modified to properly handle relocatable
3999 symbols under the new scheme,
4000 pic16createInterruptVect: is modified
4001 pic16printPublics: is modified to emit 'global' assembler directives,
4002 added pic16_printExterns to print extern symbols,
4003 pic16glue: initializes stack/frame pointer in the beginning of
4004 the assembly output. Temporary hack, will be corrected later,
4005 because gplink yet does not support stack and SDCC does not
4006 yet support a type of crt0.o object to create the final binary.
4008 * Removed many lines that contain 8051 legacy code.
4009 * The code is finally placed under a 'code' directive.
4010 * Added port specific options.
4012 * _process_pragma: simplified since now we do not need *special*
4013 include file to define SFR registers. But a separate header
4014 will be needed. This will be developed later.
4015 * _pic16_parseOptions: added, parses port specific options:
4016 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4017 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4018 --preplace-udata-with=
4020 * _pic16_setDefaultOptions: modified to initialize section names,
4021 but hack is temporarly out of order since it needs improvement.
4022 * _pic16_genAssemblerPreamble: configuration words are emitted by
4023 their address instead of their name. This part is incomplete and
4024 supports only the 18Fxx2 devices. Other devices will emit an error
4025 during assembly since they do not contain the same set of config
4027 * _pic16_genIVT: is modified,
4029 * pcode.c: added definitions for some hardware registers that are needed
4031 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4032 All PCI entries are updated. Now LFSR is supported.
4033 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4034 * added pic16_newpCodeOpLit2 to support instructions with
4035 two literal arguments
4036 * pic16_pCode2str: corrected code that emits assembler instructions
4037 with two literal operands and those that have an access bit modifier
4038 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4039 this fixes a bug which caused some labels to be lost, when an
4040 assembler directive was added, i.e. banksel,
4041 * pic16_FixRegisterBanking: improved logic that causes the insertion
4043 * InlineFunction: functions that are called once, are not any more
4044 inlined. This can be a port option in the future,
4046 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4048 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4049 hold the corresponding uninitialized symbols,
4050 * pic16_allocProcessorRegister: registers have explicit marked the
4052 * pic16_allocInternalRegister: registers are explicit marked as
4054 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4055 processing list, so bit registers were lost,
4058 * ralloc.h: added field 'accessBank' and original symbol operand
4059 in register definition,
4060 * removed the field isMapped from register definition,
4062 ** Several functions have been removed from various sources:
4063 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4064 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4065 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4066 pic16_assignRelocatableRegisters
4068 ** others have been introduced:
4069 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4070 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4072 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4074 * support/scripts/inc2h.pl: changed definition of BIT_AT
4075 to emit 'sbit at' instead of 'bit at'. This was a request.
4077 PIC16 port related preliminary changes:
4078 * gen.c: prefixed function popRegFromString with
4079 pic16_ and all references to it corrected
4080 * pcode.c: all pic16_pc_* hardware registers prefixed
4081 with underscore (_),
4082 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4083 * ralloc.c: newReg(): when register is REG_SFR then
4084 set address to rIdx,
4085 pic16_allocProcessorRegister(): marks register wasUsed=0
4086 pic16_writeUsedRegs(): added a call to assign processor
4087 registers via pic16_assignFixedRegisters
4089 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4091 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4092 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4093 variables in unused register banks. Also the SSEG is placed
4094 wherever there is enough space for it, and IDATA can be anywhere
4095 in internal RAM. For now compile using -Wl-Y[stack_size].
4096 The mem file is different for this option as well, since it
4097 makes no sense of talking about DSEG lenght.
4099 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4101 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4348 it breaks with bitfields, extern declarations, and gcse analysis.
4349 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4350 could be assigned through a pointer, so don't complain.

5092 and JUMPTABLE iCodes properly now (worked by accident before)
5093 * src/mcs51/gen.c (leftRightUseAcc),
5094 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5095 iCode properly now. Use getSize instead of nRegs since a & b
5096 aren't part of the nRegs tally.
5098 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5100 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

5106 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5107 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5108 fetching of the pointer
5109 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5110 copied from genNearPointerSet()
5111 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5112 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5113 If they pop r0/r1 they must be called in the opposite order than aopOp().
5114 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5115 (resp. --stack-auto), prepared for --xstack

5126 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5128 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5129 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5130 type for bits was changed. It resulted in bit variables becoming
5131 global, which is not permitted in PIC 14 assembly output.
5133 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5135 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5148 A few small changes that speed up the peephole optimizer.
5152 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5154 Try to make the peephole optimizer smarter by maintaining
5155 an association between the assembly source code and the
5156 iCodes that originated them. Put this information to use
5157 with a new peephole rule condition "notVolatile" so that
5158 the rules can be aggressive yet still safe.
5163 * src/mcs51/peeph.def
5165 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5169 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5170 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5171 if the left or right operand symbols have the accuse flag set.
5173 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5175 Changed the type of the result of the ! (NOT) operator to char;
5176 previously it returned the same type as the source. This allows
5177 us to eliminate all the genFloatNot functions (all of its target
5178 implementations were very buggy) since !float can use the same
5181 * src/SDCCicode.c (ast2iCode): ! returns char
5182 * src/mcs51/gen.c (genNot, genNotFloat),
5183 * src/ds390/gen.c (genNot, genNotFloat),
5184 * src/z80/gen.c (genNot, genNotFloat),
5185 * src/pic/gen.c (genNot, genNotFloat),
5186 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5188 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5190 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5191 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5192 during interrupts. Ensure WSAVE is located at a shared bank address.
5193 2. Fixed page selection in some places
5194 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5195 the registers name strings.
5196 4. Fixed "signed / unsigned compare" compiler warnings.
5197 5. The PIC port manages its own allocation of the general purpose
5198 registers, but makes no attempt to reuse them. As a result when
5199 compiling it soon runs out of general purpose registers. Some
5200 additional code was added to the files pcode.c and device.c to walk
5201 through the function call tree and rename the registers so that they
5211 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5212 genPlus() & genMinus() when the result is the same as left or right

5218 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5220 Made bitfield a distinct type from bit so that bitfields
5221 convert as per ANSI C and bits retain their traditional
5222 boolean style behaviour. Implemented bitfield support in
5230 * src/ds390/gen.c: bit v bitfield split
5231 * src/z80/gen.c: New support for bitfields
5232 * support/regression/tests/bitfields.c: reenabled z80,
5235 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5237 Rules 246.x, 247.x relate to bitfields, the others speed up
5238 access to xdata mapped I/O devices.
5240 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5242 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5244 Cleaned up genPackBits and genUnpackBits and added two helper
5245 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5246 for literal assignments in genPackBits (thanks to Frieder for
5252 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5254 Fixed bug #748310 (pointer to function type mishandled when the
5255 function name is omitted). Also fixed a SIGSEGV when a function
5256 attribute (reentrant, etc) is used on a non-function or on a
5257 function but misplaced before the parameter list.
5259 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5261 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5284 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5286 Made the constant following the "interrupt" keyword optional. If
5287 omitted, the function will not automatically be given an entry
5288 in the interrupt vector table (similar to #pragma NOIV, but
5289 less syntacticly kludgy). The interrupt number is also now
5290 range checked. Also fixed a bug in the high order bit example

5306 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5308 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5309 be re-activated by defining REDUCE_LITERALS)
5310 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5311 unsigned, but are signed by default
5312 * src/SDCCval.c (constVal): rearranged
5313 * src/SDCCval.c (valMod): preliminary fix
5314 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5766 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5767 the regression tests I'm not brave enough to enable 245.b, 245.c
5768 * doc/sdccman.lyx: added latex preamble for hyperref package.
5769 Using pdflatex this will give you a hyperlinked pdf file with
5770 bookmarks. (prepend '%' before /usepackage if this breaks something)

5808 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
5810 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
5811 it can be defined with CFLAGS when running configure
5812 * src/SDCCmain.c: fixed compiling + linking with object files
5814 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

5817 added --disable-pic16-port
5818 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
5819 * src/SDCCmain.c: linkOptions is changed to set *,
5820 added if/endif conditional macros to remove options help
5821 messages from optionsTable when a port is not configured, added
5822 support for the PIc16 port in the ports table, when executing
5823 the compiler with no port specified on command line, a default
5824 port is selected with the new macro DEFAULT_PORT which is
5825 defined in port.h, in setDefaultOptions() linkOptions is removed
5826 from initialization assignment, since now it is a set,
5827 parseCmdLine uses setParseWithComma for linkOptions, in
5828 linkEdit() linkOptions are accessed with new function indexSet()
5829 which returns the i'th item of a set variable. See SDCCset.c, in
5830 linkEdit() when calling buildCmdLine(), added linkOptions as
5831 last argument. Now users can pass arguments to gplink via the
5832 -Wl option, main() uses pic16glue() to glue up pic16 programs

5844 * src/pic16/glue.c: commented out some error producing lines
5845 * src/pic16/main.c: __config directives are commented out to stop
5846 gpasm complaining and test the linkage with gplink, _linkCmd and
5847 _asmCmd changed to be more gplink and gpasm friendly
5848 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5849 produced an error when parsed, peep rule 12 is added to utilize
5850 movff, but it is commented out since the pCode does not support
5851 yet a command with 2 address arguments
5853 2003-05-18 <johan AT balder>
5855 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5882 2003-05-11 Borut Razem <borut.razem AT siol.net>
5884 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5885 the path of bin directory, so that PATH is the only env. variable, which has to be set
5886 in case of standard installation.

6983 overlaying area for it (uses RegBankUsed[4]).
6985 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6986 bank zero as used by default. By default aslink locates the stack
6987 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6988 the creation of the .mem file. Delegates the allocation of data area
6989 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6990 the begining of the stack area to aslink.
6992 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6993 glue() in SDCCglue.c creates an area for it.
6995 2002-09-03 Borut Razem <borut.razem AT siol.net>
6996 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6997 sdcc/src/pic/glue.c:
6998 introduced atexit() handler for teporay files removal in case of
6999 errors, assertions, ...
7001 2002-08-29 Borut Razem <borut.razem AT siol.net>
7002 * sdcc/support/cpp2/auto-host_vc_in.h:
7003 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7004 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7005 Maybe there is a similar problem with BORLANDC? It should be checked!
7007 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7008 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7009 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7010 was not executed, and the compiler (cl) launched a warning:
7011 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7013 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7014 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7016 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7017 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7019 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7020 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7021 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7022 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7023 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7024 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7025 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7026 - added Release configuration in VS projects
7027 - review of compiler an linker options
7028 - VC .exe files are generated in bin_vc directory, not to interfere
7029 with binaries generated from other projects (cygwin, mingw, bcc ...)
7031 * sdcc/src/yacc.dsp: added
7033 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7034 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7035 and insert the version number definitions from .version
7037 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7039 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7040 added - genarate auto-host.h using auto-host_vc_in.h as template
7043 removed from CVS, generated automatically
7045 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7046 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7048 2002-08-11 Borut Razem <borut.razem AT siol.net>
7049 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7051 2002-08-10 Borut Razem <borut.razem AT siol.net>
7052 * src/SDCCmain.c (main):
7053 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7054 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7055 The consequence was that some temporary files were not removed.
7058 unification of code in functions tempfilename() and tempfile():
7059 function tempnam() is defined in Visual Studio 6.0 and .NET
7061 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7063 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7064 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7065 - removed compiler command line option /WX: Treats all warnings as errors
7066 - update a list of source files, included into the project
7068 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7069 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7070 changed project type to Generic Project so that can be correcly converted to VS.NET project
7072 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7074 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7076 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7078 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7079 added return 0 statements after assert() to make compiler happy
7081 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7082 added newline in the def file to keep MSC compiler satisfied
7084 * sdcc/src/z80/gen.c:
7085 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7086 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7087 - solved MSC error in function aopDump()
7089 * sdcc_vc.h: define PREFIX as "\\sdcc"
7091 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7092 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7140 Added -p option. Allows port dependent processor to be specified.
7143 Initialized the new field char *Processor field to NULL in all ports
7146 Compiler generated registers for interrupt context saving
7147 were not getting allocated.
7149 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7152 Fixed left shift. Will promote the left side of a left shift
7153 if a) left shifting more than size of operand or b) when assigned
7154 to something size > size of left side
7156 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7264 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7266 * sdcc/src/SDCCloop.c:
7267 Previous fix was not good. basic blocks that have "break" or "return" are
7268 not really partof a loop , but live ranges used in these blocks should
7269 be live thru the entire loop, so set partOfLoop but don't add them to
7272 2002-02-21 <johan AT FRIJA>
7274 * src/SDCCcse.c: fixed bug #514308
7276 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7280 statement inside a loop, it was not being considered part of the loop.
7282 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7284 2002-02-10 Karl Bongers <karl AT turbobit.com>
7287 Fixed up SDCDB debugger somewhat. Updated debugger/README
7288 with lots of comments and notes.
7290 * device/examples/test2.c:
