602 Adding support for replacing ljmps with sjmps in jumptables
603 generated for switch statements. For now you need to set the
604 environment variable SDCC_SJMP_JUMPTABLE to enable this.
605 Now 4 algorithms for mcs51 jumptable generation are used:
606 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
607 addresses loaded pc-relative for up to 112 cases and stack-pushing
608 target addresses loaded with offset from dptr for up to 256 cases.

640 * added libc directory. The current version of LibC contains string
641 functions, ctype functions and macros and some functions of the
642 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
643 be extensively tested in the future. Standard disclaimer here.
644 Library is not automatically build yet. But one can build it by

658 special compare&skip instructions. Initial tests fail some times
659 with variables grater than 1 byte in size, so new code is disabled,
660 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
662 * (genCast): began a fix to optimize the casting of a bit to another
663 bit, now assigning a bitfield to another bitfield will fail, sorry,

3569 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3571 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
3572 virus/worm forged address usage.
3574 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
3576 Fixed promotion, it should be done on AST level:
3577 * src/SDCCast.c (addCast): added promotion to int
3578 (decorateType): updated call to upCast()
3579 * src/SDCCicode.c (geniCodeLeftShift): removed call to
3580 usualUnaryConversions()
3582 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
3584 * support/regression/tests/literalop.c (mulWrapper): Added a
3585 wrapper to remove integer overflow warnings.
3587 * support/regression/tests/float_trans.c: Made work on host.
3589 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
3592 * support/regression/generate-cases.py (main): Changed from inline
3595 * doc/Makefile (install): Changed to depth first to get rid of
3596 missing directory install warning.
3598 * as/Makefile (install-doc): Made work on Mac.
3600 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3602 * src/SDCCast.c: added an additional type flow in decorateType() of
3603 opposite direction, see feature request #860006; it's enabled at runtime
3604 by setting the environment variable SDCC_NEWTYPEFLOW
3605 * src/SDCCast.h: changed prototype of decorateType()
3606 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3607 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3608 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3609 see feature request #877103
3610 * src/SDCCval.c: updated call of decorateType()
3611 (valBitwise): fixed bug #882876
3612 (valMinus): added promotion
3613 (valLogicAndOr): result is unsigned
3614 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3615 * src/SDCCsymt.c (computeType),
3616 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3617 must not cause an unsigned operation

3638 * src/pic/ralloc.h: applied patch from Slade Rich;
3639 added support for multiple code pages and multiple RAM banks on the
3640 PIC 14 port. The ASM files now no longer simply assume all the
3641 code / RAM are in the same page / bank. This means the linker can
3642 safely allocate code/RAM of separate ASM files to different pages/banks.
3643 * doc/sdccman.lyx: added Slade's tips
3644 * src/mcs51/peeph.def: fixed bug #880768

3656 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3657 strtof is not part of C89 and isn't included with Mac OS X.
3659 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3661 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3686 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3688 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3689 loaded with the linker search paths (-L arguments) and the libraries
3690 to be linked with the current source (-l arguments). Changes
3691 currently will affect only the pic16 port.
3692 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3693 include path the port specific paths and port specific libraries,
3694 * gplink command now contains the $3 argument,
3695 * src/pic16/device.h,
3696 * src/pic16/device.c,: structure PIC_device is made public and
3697 renamed to PIC16_device, the same for variable Pics which is renamed

3712 Documenting changes from previous commits.
3713 * configure.in (version 1.56),
3714 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3715 when generating output files to configure the pic16 library,
3716 but now I've commented it out, since gputils aren't installed in the
3717 SF compile farm, so library won't compile
3719 * device/lib/Makefile.in (version 1.56): initially I've added in
3720 target 'all' the prerequestive 'model-pic16' so it compiled the
3721 pic16 library, but now I've commented it out for the same reasons
3723 * added targets 'model-pic16' and 'objects-pic16' to compile the
3725 * added target 'port-specific-objects-pic16' to handle the
3726 generated libraries and copy them into the build/ directory
3727 * added target 'clean-intermediate-pic16' to clean intermediate
3728 files into pic16 directory
3729 * in target 'installdirs' added line to create directory pic16 in
3730 the installation path
3732 * device/include/Makefile.in (version 1.11): in target 'install'
3733 added lines to copy all header files to installation path,
3734 * in target 'installdirs' added line create directory for pic16
3735 headers in the installation path

3750 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3751 option so that it actually works. Made it specific to the z80, since
3752 the gbz80 doesn't have these kinds of I/O ports.
3754 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3756 * device/include/z180.h,

3778 Mainly changes to support compilation of the device libraries
3779 * src/pic16/device.c: stack is allocated via symbol and not
3780 via literal number. The symbol is placed in the corresponding
3781 position of the data ram
3782 * (pic16_dump_section): relocatable and absolute uninitialized
3783 data are now emitted in sorted order to reduce section naming,
3784 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3785 weren't marked as being in the access bank,
3787 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3789 Added portion of GNU PIC Library under the directory
3790 device/include/pic16 and device/lib/pic16. These files
3791 contain the declarations of SFRs for the PIC18Fxx2 devices.
3792 The directory is initialized via configure from toplevel.
3794 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3796 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3822 all over. Telling LaTeX to be less strict with word spacing
3823 to better keep the right margin. Changed some notes about
3824 maintainance of the ports in section 3.2.1 - is it OK like this?
3826 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3864 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3866 * src/pic16/peeph.def: all peepholes with movff are commented out,
3867 because there is a problem in the pcode peep optimizer,
3868 * src/pic16/ralloc.c: the register allocator can now reuse local

3870 * src/pic16/ralloc.h: added flag isLocal in structure regs,
3872 Added file src/pic16/NOTES with information about program writing on
3873 the current port version.

3933 directive when no overlay data exist
3934 * (picglue): modified to emit uninitialized data segment
3935 according to udata_section_name

4007 Bug reported from Jesus Calvino-Fraga
4009 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4011 * sdcc.spec: updated
4012 * device/include/Makefile.in: don't install CVS directories

4020 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4022 PIC16 port related changes:
4023 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4024 added variable stackPos,
4026 * gen.c: genCall, assignResultValue: added support for
4027 pushing/retrieving function parameters to/from stack,
4028 genFunction,genEndFunction: setup stack frame for the
4030 genAddrOf: will be changed according to bug 863624
4032 * added files genutils.c and genutils.h which contain gen*
4033 debugged and optimised functions extracted from gen.c
4035 * glue.c: added variable 'externs' which holds extern symbols,
4036 pic16emitRegularMap: is modified to properly handle relocatable
4037 symbols under the new scheme,
4038 pic16createInterruptVect: is modified
4039 pic16printPublics: is modified to emit 'global' assembler directives,
4040 added pic16_printExterns to print extern symbols,
4041 pic16glue: initializes stack/frame pointer in the beginning of
4042 the assembly output. Temporary hack, will be corrected later,
4043 because gplink yet does not support stack and SDCC does not
4044 yet support a type of crt0.o object to create the final binary.
4046 * Removed many lines that contain 8051 legacy code.
4047 * The code is finally placed under a 'code' directive.
4048 * Added port specific options.
4050 * _process_pragma: simplified since now we do not need *special*
4051 include file to define SFR registers. But a separate header
4052 will be needed. This will be developed later.
4053 * _pic16_parseOptions: added, parses port specific options:
4054 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4055 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4056 --preplace-udata-with=
4058 * _pic16_setDefaultOptions: modified to initialize section names,
4059 but hack is temporarly out of order since it needs improvement.
4060 * _pic16_genAssemblerPreamble: configuration words are emitted by
4061 their address instead of their name. This part is incomplete and
4062 supports only the 18Fxx2 devices. Other devices will emit an error
4063 during assembly since they do not contain the same set of config
4065 * _pic16_genIVT: is modified,
4067 * pcode.c: added definitions for some hardware registers that are needed
4069 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4070 All PCI entries are updated. Now LFSR is supported.
4071 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4072 * added pic16_newpCodeOpLit2 to support instructions with
4073 two literal arguments
4074 * pic16_pCode2str: corrected code that emits assembler instructions
4075 with two literal operands and those that have an access bit modifier
4076 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4077 this fixes a bug which caused some labels to be lost, when an
4078 assembler directive was added, i.e. banksel,
4079 * pic16_FixRegisterBanking: improved logic that causes the insertion
4081 * InlineFunction: functions that are called once, are not any more
4082 inlined. This can be a port option in the future,
4084 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4086 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4087 hold the corresponding uninitialized symbols,
4088 * pic16_allocProcessorRegister: registers have explicit marked the
4090 * pic16_allocInternalRegister: registers are explicit marked as
4092 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4093 processing list, so bit registers were lost,
4096 * ralloc.h: added field 'accessBank' and original symbol operand
4097 in register definition,
4098 * removed the field isMapped from register definition,
4100 ** Several functions have been removed from various sources:
4101 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4102 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4103 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4104 pic16_assignRelocatableRegisters
4106 ** others have been introduced:
4107 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4108 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4110 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4112 * support/scripts/inc2h.pl: changed definition of BIT_AT
4113 to emit 'sbit at' instead of 'bit at'. This was a request.
4115 PIC16 port related preliminary changes:
4116 * gen.c: prefixed function popRegFromString with
4117 pic16_ and all references to it corrected
4118 * pcode.c: all pic16_pc_* hardware registers prefixed
4119 with underscore (_),
4120 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4121 * ralloc.c: newReg(): when register is REG_SFR then
4122 set address to rIdx,
4123 pic16_allocProcessorRegister(): marks register wasUsed=0
4124 pic16_writeUsedRegs(): added a call to assign processor
4125 registers via pic16_assignFixedRegisters
4127 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4129 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4130 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4131 variables in unused register banks. Also the SSEG is placed
4132 wherever there is enough space for it, and IDATA can be anywhere
4133 in internal RAM. For now compile using -Wl-Y[stack_size].
4134 The mem file is different for this option as well, since it
4135 makes no sense of talking about DSEG lenght.
4137 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4139 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4140 in certain cases, e.g. when ROM assignment, patch provided
4141 from Albert den Haan.

4384 * src/SDCCast.c (decorateType): disabled a transformation I added in
4385 revision 1.188 (access to fields of a structure at an absolute address);
4386 it breaks with bitfields, extern declarations, and gcse analysis.
4387 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4388 could be assigned through a pointer, so don't complain.

4496 xdata initialization slightly shorter
4498 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5145 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5146 fetching of the pointer
5147 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5148 copied from genNearPointerSet()
5149 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5150 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5166 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5167 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5168 type for bits was changed. It resulted in bit variables becoming
5169 global, which is not permitted in PIC 14 assembly output.
5171 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5173 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5186 A few small changes that speed up the peephole optimizer.
5190 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5192 Try to make the peephole optimizer smarter by maintaining
5193 an association between the assembly source code and the
5194 iCodes that originated them. Put this information to use
5195 with a new peephole rule condition "notVolatile" so that
5196 the rules can be aggressive yet still safe.
5201 * src/mcs51/peeph.def
5203 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5207 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5208 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5209 if the left or right operand symbols have the accuse flag set.
5211 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5213 Changed the type of the result of the ! (NOT) operator to char;
5214 previously it returned the same type as the source. This allows
5215 us to eliminate all the genFloatNot functions (all of its target
5216 implementations were very buggy) since !float can use the same
5219 * src/SDCCicode.c (ast2iCode): ! returns char

5228 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5229 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5230 during interrupts. Ensure WSAVE is located at a shared bank address.
5231 2. Fixed page selection in some places
5232 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5233 the registers name strings.
5234 4. Fixed "signed / unsigned compare" compiler warnings.
5235 5. The PIC port manages its own allocation of the general purpose
5236 registers, but makes no attempt to reuse them. As a result when
5237 compiling it soon runs out of general purpose registers. Some
5238 additional code was added to the files pcode.c and device.c to walk
5239 through the function call tree and rename the registers so that they
5249 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5250 genPlus() & genMinus() when the result is the same as left or right

5256 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5258 Made bitfield a distinct type from bit so that bitfields
5259 convert as per ANSI C and bits retain their traditional
5260 boolean style behaviour. Implemented bitfield support in
5268 * src/ds390/gen.c: bit v bitfield split
5269 * src/z80/gen.c: New support for bitfields
5270 * support/regression/tests/bitfields.c: reenabled z80,
5273 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5275 Rules 246.x, 247.x relate to bitfields, the others speed up
5276 access to xdata mapped I/O devices.
5278 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5280 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5282 Cleaned up genPackBits and genUnpackBits and added two helper
5283 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5284 for literal assignments in genPackBits (thanks to Frieder for
5290 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5292 Fixed bug #748310 (pointer to function type mishandled when the
5293 function name is omitted). Also fixed a SIGSEGV when a function
5294 attribute (reentrant, etc) is used on a non-function or on a
5295 function but misplaced before the parameter list.
5297 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5299 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5300 * support/Util/SDCCerr.h,

5322 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5324 Made the constant following the "interrupt" keyword optional. If
5325 omitted, the function will not automatically be given an entry
5326 in the interrupt vector table (similar to #pragma NOIV, but
5327 less syntacticly kludgy). The interrupt number is also now
5328 range checked. Also fixed a bug in the high order bit example

5336 * support/Util/SDCCerr.h
5339 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5342 * src/SDCCicode.c (operandOperation): rewritten some ops
5343 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5344 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5346 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5347 be re-activated by defining REDUCE_LITERALS)
5348 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5349 unsigned, but are signed by default
5350 * src/SDCCval.c (constVal): rearranged
5351 * src/SDCCval.c (valMod): preliminary fix
5352 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5394 constants are unsigned; added recognition of "u" flag for unsigned
5395 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5396 * src/SDCCval.c (valDiv, valMod): fixed signdness
5397 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5398 signedness of modulo, left and right shift

5857 * src/SDCCmain.c: linkOptions is changed to set *,
5858 added if/endif conditional macros to remove options help
5859 messages from optionsTable when a port is not configured, added
5860 support for the PIc16 port in the ports table, when executing
5861 the compiler with no port specified on command line, a default
5862 port is selected with the new macro DEFAULT_PORT which is
5863 defined in port.h, in setDefaultOptions() linkOptions is removed
5864 from initialization assignment, since now it is a set,
5865 parseCmdLine uses setParseWithComma for linkOptions, in
5866 linkEdit() linkOptions are accessed with new function indexSet()
5867 which returns the i'th item of a set variable. See SDCCset.c, in
5868 linkEdit() when calling buildCmdLine(), added linkOptions as
5869 last argument. Now users can pass arguments to gplink via the
5870 -Wl option, main() uses pic16glue() to glue up pic16 programs

5882 * src/pic16/glue.c: commented out some error producing lines
5883 * src/pic16/main.c: __config directives are commented out to stop
5884 gpasm complaining and test the linkage with gplink, _linkCmd and
5885 _asmCmd changed to be more gplink and gpasm friendly
5886 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5887 produced an error when parsed, peep rule 12 is added to utilize
5888 movff, but it is commented out since the pCode does not support
5889 yet a command with 2 address arguments
5891 2003-05-18 <johan AT balder>
5893 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
5894 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5920 2003-05-11 Borut Razem <borut.razem AT siol.net>
5922 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5923 the path of bin directory, so that PATH is the only env. variable, which has to be set
5924 in case of standard installation.
5925 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

6982 added aopGetUsesAcc() function to allow binary operators to
6983 fetch their operands in the correct order; made genMinus() emit
6984 compact code for X = LITERAL - Y
6986 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6987 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6988 sprintf() in line 1267.
6990 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6991 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6994 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6995 Changes to aslink (All the changes are marked with 'JCF'):
6997 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7000 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7001 area BSEG. Also moves, if possible, the DATA area down into the internal
7002 ram so more space is available.
7004 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7007 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7008 not bytes. Function summary() which creates a memory usage summary
7009 file with extension .mem. Reports of overlaping stack and small stack
7010 size. If the space for the stack is less than 16 bytes aslink trows a
7013 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7014 the 8051. Option 'y' for memory summary output file.
7016 Changes to sdcc (All the changes are marked with 'JCF'):
7018 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7020 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7021 overlaying area for it (uses RegBankUsed[4]).
7023 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7024 bank zero as used by default. By default aslink locates the stack
7025 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7026 the creation of the .mem file. Delegates the allocation of data area
7027 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7028 the begining of the stack area to aslink.
7030 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7031 glue() in SDCCglue.c creates an area for it.
7033 2002-09-03 Borut Razem <borut.razem AT siol.net>
7034 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7035 sdcc/src/pic/glue.c:
7036 introduced atexit() handler for teporay files removal in case of
7037 errors, assertions, ...
7039 2002-08-29 Borut Razem <borut.razem AT siol.net>
7040 * sdcc/support/cpp2/auto-host_vc_in.h:
7041 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7042 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7043 Maybe there is a similar problem with BORLANDC? It should be checked!
7045 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7046 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7047 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7048 was not executed, and the compiler (cl) launched a warning:
7049 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7051 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7052 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7054 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7055 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7057 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7058 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7059 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7060 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7061 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7062 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7063 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7064 - added Release configuration in VS projects
7065 - review of compiler an linker options
7066 - VC .exe files are generated in bin_vc directory, not to interfere
7067 with binaries generated from other projects (cygwin, mingw, bcc ...)
7069 * sdcc/src/yacc.dsp: added
7071 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7072 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7073 and insert the version number definitions from .version
7075 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7077 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7078 added - genarate auto-host.h using auto-host_vc_in.h as template
7081 removed from CVS, generated automatically
7083 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7084 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7086 2002-08-11 Borut Razem <borut.razem AT siol.net>
7087 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7089 2002-08-10 Borut Razem <borut.razem AT siol.net>
7090 * src/SDCCmain.c (main):
7091 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7092 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7093 The consequence was that some temporary files were not removed.
7096 unification of code in functions tempfilename() and tempfile():
7097 function tempnam() is defined in Visual Studio 6.0 and .NET
7099 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7101 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7102 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7103 - removed compiler command line option /WX: Treats all warnings as errors
7104 - update a list of source files, included into the project
7106 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7107 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7108 changed project type to Generic Project so that can be correcly converted to VS.NET project
7110 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7112 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7114 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7116 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7117 added return 0 statements after assert() to make compiler happy
7119 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7120 added newline in the def file to keep MSC compiler satisfied
7122 * sdcc/src/z80/gen.c:
7123 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7124 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7125 - solved MSC error in function aopDump()
7127 * sdcc_vc.h: define PREFIX as "\\sdcc"
7129 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7130 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7169 2002-03-28 Johan Knol <johan AT balder>
7171 * src/SDCCval.c: fixed bug #532436
7173 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7175 Added "char *Processor" field to the port structure.
7178 Added -p option. Allows port dependent processor to be specified.
7181 Initialized the new field char *Processor field to NULL in all ports
7184 Compiler generated registers for interrupt context saving
7185 were not getting allocated.
7187 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7190 Fixed left shift. Will promote the left side of a left shift
7191 if a) left shifting more than size of operand or b) when assigned
7192 to something size > size of left side
7194 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7196 tons of changes. Register allocation has been
7197 rewritten. Added customization for the various PICs. Flow

7302 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7304 * sdcc/src/SDCCloop.c:
7305 Previous fix was not good. basic blocks that have "break" or "return" are
7306 not really partof a loop , but live ranges used in these blocks should
7307 be live thru the entire loop, so set partOfLoop but don't add them to
7310 2002-02-21 <johan AT FRIJA>
7312 * src/SDCCcse.c: fixed bug #514308
7314 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7317 Fixed BUG #519583. If a conditional block ended in a return/break
7318 statement inside a loop, it was not being considered part of the loop.
7320 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7322 2002-02-10 Karl Bongers <karl AT turbobit.com>
7325 Fixed up SDCDB debugger somewhat. Updated debugger/README
7326 with lots of comments and notes.
7328 * device/examples/test2.c:
7329 Fix bug, "red" variable not being initialized(compiler complained).
