586 Adding support for replacing ljmps with sjmps in jumptables
587 generated for switch statements. For now you need to set the
588 environment variable SDCC_SJMP_JUMPTABLE to enable this.
589 Now 4 algorithms for mcs51 jumptable generation are used:
590 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

624 * added libc directory. The current version of LibC contains string
625 functions, ctype functions and macros and some functions of the
626 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
627 be extensively tested in the future. Standard disclaimer here.
628 Library is not automatically build yet. But one can build it by
629 invoking 'make' inside the libc directory.

644 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
646 * (genCast): began a fix to optimize the casting of a bit to another
647 bit, now assigning a bitfield to another bitfield will fail, sorry,

3573 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
3576 * support/regression/generate-cases.py (main): Changed from inline
3579 * doc/Makefile (install): Changed to depth first to get rid of
3580 missing directory install warning.
3582 * as/Makefile (install-doc): Made work on Mac.
3584 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3586 * src/SDCCast.c: added an additional type flow in decorateType() of
3587 opposite direction, see feature request #860006; it's enabled at runtime
3588 by setting the environment variable SDCC_NEWTYPEFLOW
3589 * src/SDCCast.h: changed prototype of decorateType()
3590 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3591 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3592 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3593 see feature request #877103
3594 * src/SDCCval.c: updated call of decorateType()
3595 (valBitwise): fixed bug #882876
3596 (valMinus): added promotion
3597 (valLogicAndOr): result is unsigned
3598 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3599 * src/SDCCsymt.c (computeType),
3600 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3601 must not cause an unsigned operation
3602 * src/pic/glue (pic14emitRegularMap),
3603 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3605 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

3622 * src/pic/ralloc.h: applied patch from Slade Rich;
3623 added support for multiple code pages and multiple RAM banks on the
3624 PIC 14 port. The ASM files now no longer simply assume all the
3625 code / RAM are in the same page / bank. This means the linker can
3626 safely allocate code/RAM of separate ASM files to different pages/banks.
3627 * doc/sdccman.lyx: added Slade's tips
3628 * src/mcs51/peeph.def: fixed bug #880768

3640 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3641 strtof is not part of C89 and isn't included with Mac OS X.
3643 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3645 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3670 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3672 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3673 loaded with the linker search paths (-L arguments) and the libraries
3674 to be linked with the current source (-l arguments). Changes
3675 currently will affect only the pic16 port.
3676 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3677 include path the port specific paths and port specific libraries,
3678 * gplink command now contains the $3 argument,
3679 * src/pic16/device.h,
3680 * src/pic16/device.c,: structure PIC_device is made public and
3681 renamed to PIC16_device, the same for variable Pics which is renamed

3696 Documenting changes from previous commits.
3697 * configure.in (version 1.56),
3698 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3699 when generating output files to configure the pic16 library,
3700 but now I've commented it out, since gputils aren't installed in the
3701 SF compile farm, so library won't compile
3703 * device/lib/Makefile.in (version 1.56): initially I've added in
3704 target 'all' the prerequestive 'model-pic16' so it compiled the
3705 pic16 library, but now I've commented it out for the same reasons
3707 * added targets 'model-pic16' and 'objects-pic16' to compile the
3709 * added target 'port-specific-objects-pic16' to handle the
3710 generated libraries and copy them into the build/ directory
3711 * added target 'clean-intermediate-pic16' to clean intermediate
3712 files into pic16 directory
3713 * in target 'installdirs' added line to create directory pic16 in
3714 the installation path
3716 * device/include/Makefile.in (version 1.11): in target 'install'
3717 added lines to copy all header files to installation path,
3718 * in target 'installdirs' added line create directory for pic16
3719 headers in the installation path

3734 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3735 option so that it actually works. Made it specific to the z80, since
3736 the gbz80 doesn't have these kinds of I/O ports.
3738 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3740 * device/include/z180.h,

3762 Mainly changes to support compilation of the device libraries
3763 * src/pic16/device.c: stack is allocated via symbol and not
3764 via literal number. The symbol is placed in the corresponding
3765 position of the data ram
3766 * (pic16_dump_section): relocatable and absolute uninitialized
3767 data are now emitted in sorted order to reduce section naming,
3768 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3769 weren't marked as being in the access bank,
3771 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3773 Added portion of GNU PIC Library under the directory
3774 device/include/pic16 and device/lib/pic16. These files
3775 contain the declarations of SFRs for the PIC18Fxx2 devices.
3776 The directory is initialized via configure from toplevel.
3778 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

3806 all over. Telling LaTeX to be less strict with word spacing
3807 to better keep the right margin. Changed some notes about
3808 maintainance of the ports in section 3.2.1 - is it OK like this?
3810 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3848 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3850 * src/pic16/peeph.def: all peepholes with movff are commented out,
3851 because there is a problem in the pcode peep optimizer,
3852 * src/pic16/ralloc.c: the register allocator can now reuse local

3991 Bug reported from Jesus Calvino-Fraga
3993 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3995 * sdcc.spec: updated
3996 * device/include/Makefile.in: don't install CVS directories

3999 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4000 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4001 * src/ds390/gen.c (genRightShift): fixed bug #870788
4002 * src/SDCCast.c (decorateType): fixed bug #870781
4004 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4006 PIC16 port related changes:
4007 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4008 added variable stackPos,
4010 * gen.c: genCall, assignResultValue: added support for
4011 pushing/retrieving function parameters to/from stack,
4012 genFunction,genEndFunction: setup stack frame for the
4014 genAddrOf: will be changed according to bug 863624
4016 * added files genutils.c and genutils.h which contain gen*
4017 debugged and optimised functions extracted from gen.c
4019 * glue.c: added variable 'externs' which holds extern symbols,
4020 pic16emitRegularMap: is modified to properly handle relocatable
4021 symbols under the new scheme,
4022 pic16createInterruptVect: is modified
4023 pic16printPublics: is modified to emit 'global' assembler directives,
4024 added pic16_printExterns to print extern symbols,
4025 pic16glue: initializes stack/frame pointer in the beginning of
4026 the assembly output. Temporary hack, will be corrected later,
4027 because gplink yet does not support stack and SDCC does not
4028 yet support a type of crt0.o object to create the final binary.
4030 * Removed many lines that contain 8051 legacy code.
4031 * The code is finally placed under a 'code' directive.
4032 * Added port specific options.
4034 * _process_pragma: simplified since now we do not need *special*
4035 include file to define SFR registers. But a separate header
4036 will be needed. This will be developed later.
4037 * _pic16_parseOptions: added, parses port specific options:
4038 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4039 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4040 --preplace-udata-with=
4042 * _pic16_setDefaultOptions: modified to initialize section names,
4043 but hack is temporarly out of order since it needs improvement.
4044 * _pic16_genAssemblerPreamble: configuration words are emitted by
4045 their address instead of their name. This part is incomplete and
4046 supports only the 18Fxx2 devices. Other devices will emit an error
4047 during assembly since they do not contain the same set of config
4049 * _pic16_genIVT: is modified,
4051 * pcode.c: added definitions for some hardware registers that are needed
4053 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4054 All PCI entries are updated. Now LFSR is supported.
4055 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4056 * added pic16_newpCodeOpLit2 to support instructions with
4057 two literal arguments
4058 * pic16_pCode2str: corrected code that emits assembler instructions
4059 with two literal operands and those that have an access bit modifier
4060 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4061 this fixes a bug which caused some labels to be lost, when an
4062 assembler directive was added, i.e. banksel,
4063 * pic16_FixRegisterBanking: improved logic that causes the insertion
4065 * InlineFunction: functions that are called once, are not any more
4066 inlined. This can be a port option in the future,
4068 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4070 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4071 hold the corresponding uninitialized symbols,
4072 * pic16_allocProcessorRegister: registers have explicit marked the
4074 * pic16_allocInternalRegister: registers are explicit marked as
4076 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4077 processing list, so bit registers were lost,
4080 * ralloc.h: added field 'accessBank' and original symbol operand
4081 in register definition,
4082 * removed the field isMapped from register definition,
4084 ** Several functions have been removed from various sources:
4085 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4086 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4087 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4088 pic16_assignRelocatableRegisters
4090 ** others have been introduced:
4091 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4092 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4094 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4096 * support/scripts/inc2h.pl: changed definition of BIT_AT
4097 to emit 'sbit at' instead of 'bit at'. This was a request.
4099 PIC16 port related preliminary changes:
4100 * gen.c: prefixed function popRegFromString with
4101 pic16_ and all references to it corrected
4102 * pcode.c: all pic16_pc_* hardware registers prefixed
4103 with underscore (_),
4104 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4105 * ralloc.c: newReg(): when register is REG_SFR then
4106 set address to rIdx,
4107 pic16_allocProcessorRegister(): marks register wasUsed=0
4108 pic16_writeUsedRegs(): added a call to assign processor
4109 registers via pic16_assignFixedRegisters
4111 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4113 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4114 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4115 variables in unused register banks. Also the SSEG is placed
4116 wherever there is enough space for it, and IDATA can be anywhere
4117 in internal RAM. For now compile using -Wl-Y[stack_size].
4118 The mem file is different for this option as well, since it
4119 makes no sense of talking about DSEG lenght.
4121 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4123 * src/SDCClrange.c: fixed bug 869095 that caused segfault

4368 * src/SDCCast.c (decorateType): disabled a transformation I added in
4369 revision 1.188 (access to fields of a structure at an absolute address);
4370 it breaks with bitfields, extern declarations, and gcse analysis.
4371 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4372 could be assigned through a pointer, so don't complain.

4480 xdata initialization slightly shorter
4482 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5129 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5130 fetching of the pointer
5131 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5132 copied from genNearPointerSet()
5133 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5134 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5148 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5150 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5151 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5152 type for bits was changed. It resulted in bit variables becoming
5153 global, which is not permitted in PIC 14 assembly output.
5155 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5157 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5170 A few small changes that speed up the peephole optimizer.
5174 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5176 Try to make the peephole optimizer smarter by maintaining
5177 an association between the assembly source code and the
5178 iCodes that originated them. Put this information to use
5179 with a new peephole rule condition "notVolatile" so that
5180 the rules can be aggressive yet still safe.
5185 * src/mcs51/peeph.def
5187 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5191 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5192 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5193 if the left or right operand symbols have the accuse flag set.
5195 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5197 Changed the type of the result of the ! (NOT) operator to char;
5198 previously it returned the same type as the source. This allows
5199 us to eliminate all the genFloatNot functions (all of its target
5200 implementations were very buggy) since !float can use the same
5203 * src/SDCCicode.c (ast2iCode): ! returns char
5204 * src/mcs51/gen.c (genNot, genNotFloat),
5205 * src/ds390/gen.c (genNot, genNotFloat),
5206 * src/z80/gen.c (genNot, genNotFloat),
5207 * src/pic/gen.c (genNot, genNotFloat),
5208 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5210 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5212 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5213 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5214 during interrupts. Ensure WSAVE is located at a shared bank address.
5215 2. Fixed page selection in some places
5216 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5217 the registers name strings.
5218 4. Fixed "signed / unsigned compare" compiler warnings.
5219 5. The PIC port manages its own allocation of the general purpose
5220 registers, but makes no attempt to reuse them. As a result when
5221 compiling it soon runs out of general purpose registers. Some
5222 additional code was added to the files pcode.c and device.c to walk
5223 through the function call tree and rename the registers so that they
5233 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5234 genPlus() & genMinus() when the result is the same as left or right

5240 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5242 Made bitfield a distinct type from bit so that bitfields
5243 convert as per ANSI C and bits retain their traditional
5244 boolean style behaviour. Implemented bitfield support in
5252 * src/ds390/gen.c: bit v bitfield split
5253 * src/z80/gen.c: New support for bitfields
5254 * support/regression/tests/bitfields.c: reenabled z80,
5257 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5259 Rules 246.x, 247.x relate to bitfields, the others speed up
5260 access to xdata mapped I/O devices.
5262 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5264 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5266 Cleaned up genPackBits and genUnpackBits and added two helper
5267 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5268 for literal assignments in genPackBits (thanks to Frieder for
5274 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5276 Fixed bug #748310 (pointer to function type mishandled when the
5277 function name is omitted). Also fixed a SIGSEGV when a function
5278 attribute (reentrant, etc) is used on a non-function or on a
5279 function but misplaced before the parameter list.
5281 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5283 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5306 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5308 Made the constant following the "interrupt" keyword optional. If
5309 omitted, the function will not automatically be given an entry
5310 in the interrupt vector table (similar to #pragma NOIV, but
5311 less syntacticly kludgy). The interrupt number is also now
5312 range checked. Also fixed a bug in the high order bit example

5326 * src/SDCCicode.c (operandOperation): rewritten some ops
5327 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5328 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5330 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5331 be re-activated by defining REDUCE_LITERALS)
5332 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5333 unsigned, but are signed by default
5334 * src/SDCCval.c (constVal): rearranged
5335 * src/SDCCval.c (valMod): preliminary fix
5336 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5841 * src/SDCCmain.c: linkOptions is changed to set *,
5842 added if/endif conditional macros to remove options help
5843 messages from optionsTable when a port is not configured, added
5844 support for the PIc16 port in the ports table, when executing
5845 the compiler with no port specified on command line, a default
5846 port is selected with the new macro DEFAULT_PORT which is
5847 defined in port.h, in setDefaultOptions() linkOptions is removed
5848 from initialization assignment, since now it is a set,
5849 parseCmdLine uses setParseWithComma for linkOptions, in
5850 linkEdit() linkOptions are accessed with new function indexSet()
5851 which returns the i'th item of a set variable. See SDCCset.c, in
5852 linkEdit() when calling buildCmdLine(), added linkOptions as
5853 last argument. Now users can pass arguments to gplink via the
5854 -Wl option, main() uses pic16glue() to glue up pic16 programs

5866 * src/pic16/glue.c: commented out some error producing lines
5867 * src/pic16/main.c: __config directives are commented out to stop
5868 gpasm complaining and test the linkage with gplink, _linkCmd and
5869 _asmCmd changed to be more gplink and gpasm friendly
5870 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5871 produced an error when parsed, peep rule 12 is added to utilize
5872 movff, but it is commented out since the pCode does not support
5873 yet a command with 2 address arguments
5875 2003-05-18 <johan AT balder>
5877 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5904 2003-05-11 Borut Razem <borut.razem AT siol.net>
5906 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5907 the path of bin directory, so that PATH is the only env. variable, which has to be set
5908 in case of standard installation.

6991 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6992 not bytes. Function summary() which creates a memory usage summary
6993 file with extension .mem. Reports of overlaping stack and small stack
6994 size. If the space for the stack is less than 16 bytes aslink trows a
6997 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6998 the 8051. Option 'y' for memory summary output file.
7000 Changes to sdcc (All the changes are marked with 'JCF'):
7002 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7004 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7005 overlaying area for it (uses RegBankUsed[4]).
7007 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7008 bank zero as used by default. By default aslink locates the stack
7009 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7010 the creation of the .mem file. Delegates the allocation of data area
7011 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7012 the begining of the stack area to aslink.
7014 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7015 glue() in SDCCglue.c creates an area for it.
7017 2002-09-03 Borut Razem <borut.razem AT siol.net>
7018 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7019 sdcc/src/pic/glue.c:
7020 introduced atexit() handler for teporay files removal in case of
7021 errors, assertions, ...
7023 2002-08-29 Borut Razem <borut.razem AT siol.net>
7024 * sdcc/support/cpp2/auto-host_vc_in.h:
7025 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7026 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7027 Maybe there is a similar problem with BORLANDC? It should be checked!
7029 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7030 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7031 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7032 was not executed, and the compiler (cl) launched a warning:
7033 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7035 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7036 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7038 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7039 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7041 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7042 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7043 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7044 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7045 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7046 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7047 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7048 - added Release configuration in VS projects
7049 - review of compiler an linker options
7050 - VC .exe files are generated in bin_vc directory, not to interfere
7051 with binaries generated from other projects (cygwin, mingw, bcc ...)
7053 * sdcc/src/yacc.dsp: added
7055 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7056 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7057 and insert the version number definitions from .version
7059 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7061 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7062 added - genarate auto-host.h using auto-host_vc_in.h as template
7065 removed from CVS, generated automatically
7067 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7068 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7070 2002-08-11 Borut Razem <borut.razem AT siol.net>
7071 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7073 2002-08-10 Borut Razem <borut.razem AT siol.net>
7074 * src/SDCCmain.c (main):
7075 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7076 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7077 The consequence was that some temporary files were not removed.
7080 unification of code in functions tempfilename() and tempfile():
7081 function tempnam() is defined in Visual Studio 6.0 and .NET
7083 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7085 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7086 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7087 - removed compiler command line option /WX: Treats all warnings as errors
7088 - update a list of source files, included into the project
7090 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7091 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7092 changed project type to Generic Project so that can be correcly converted to VS.NET project
7094 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7096 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7098 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7100 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7101 added return 0 statements after assert() to make compiler happy
7103 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7104 added newline in the def file to keep MSC compiler satisfied
7106 * sdcc/src/z80/gen.c:
7107 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7108 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7109 - solved MSC error in function aopDump()
7111 * sdcc_vc.h: define PREFIX as "\\sdcc"
7113 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7114 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7165 Initialized the new field char *Processor field to NULL in all ports
7168 Compiler generated registers for interrupt context saving
7169 were not getting allocated.
7171 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7174 Fixed left shift. Will promote the left side of a left shift
7175 if a) left shifting more than size of operand or b) when assigned
7176 to something size > size of left side
7178 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7286 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7288 * sdcc/src/SDCCloop.c:
7289 Previous fix was not good. basic blocks that have "break" or "return" are
7290 not really partof a loop , but live ranges used in these blocks should
7291 be live thru the entire loop, so set partOfLoop but don't add them to
7294 2002-02-21 <johan AT FRIJA>
7296 * src/SDCCcse.c: fixed bug #514308
7298 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7302 statement inside a loop, it was not being considered part of the loop.
7304 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7306 2002-02-10 Karl Bongers <karl AT turbobit.com>
7309 Fixed up SDCDB debugger somewhat. Updated debugger/README
7310 with lots of comments and notes.
7312 * device/examples/test2.c:
7313 Fix bug, "red" variable not being initialized(compiler complained).

7317 for use as a multiple module SDCDB test case.
7319 * sim/ucsim/cmd.src/cmdset.cc:
7320 Took out debug printfs in ucsim "next" command.
7323 Karl and Johan start ucsim XA support. Most dissassembly working,
7324 about 75% emulation done(plenty of work remaining).
