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

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

3579 * src/SDCCast.c: added an additional type flow in decorateType() of
3580 opposite direction, see feature request #860006; it's enabled at runtime
3581 by setting the environment variable SDCC_NEWTYPEFLOW
3582 * src/SDCCast.h: changed prototype of decorateType()
3583 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3584 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3585 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3586 see feature request #877103
3587 * src/SDCCval.c: updated call of decorateType()
3588 (valBitwise): fixed bug #882876
3589 (valMinus): added promotion
3590 (valLogicAndOr): result is unsigned
3591 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3592 * src/SDCCsymt.c (computeType),
3593 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3594 must not cause an unsigned operation
3595 * src/pic/glue (pic14emitRegularMap),
3596 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
3598 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
3600 * src/pic/pcode.c (PCodeID): commented out left over debug code
3602 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
3604 * support/valdiag/tests/overflow.c: added shift tests

3613 * src/pic/pcoderegs.c,
3615 * src/pic/ralloc.h: applied patch from Slade Rich;
3616 added support for multiple code pages and multiple RAM banks on the
3617 PIC 14 port. The ASM files now no longer simply assume all the
3618 code / RAM are in the same page / bank. This means the linker can
3619 safely allocate code/RAM of separate ASM files to different pages/banks.
3620 * doc/sdccman.lyx: added Slade's tips
3621 * src/mcs51/peeph.def: fixed bug #880768

3630 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
3633 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3634 strtof is not part of C89 and isn't included with Mac OS X.
3636 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3638 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3660 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
3663 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3665 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3666 loaded with the linker search paths (-L arguments) and the libraries
3667 to be linked with the current source (-l arguments). Changes
3668 currently will affect only the pic16 port.
3669 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3670 include path the port specific paths and port specific libraries,
3671 * gplink command now contains the $3 argument,
3672 * src/pic16/device.h,
3673 * src/pic16/device.c,: structure PIC_device is made public and
3674 renamed to PIC16_device, the same for variable Pics which is renamed
3675 to Pics16. Updated all references to them.
3676 * src/pic16/glue.c (pic16glue): corrected bug with code
3677 initialization which bypassed the variable initializations block.

3689 Documenting changes from previous commits.
3690 * configure.in (version 1.56),
3691 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3692 when generating output files to configure the pic16 library,
3693 but now I've commented it out, since gputils aren't installed in the
3694 SF compile farm, so library won't compile
3696 * device/lib/Makefile.in (version 1.56): initially I've added in
3697 target 'all' the prerequestive 'model-pic16' so it compiled the
3698 pic16 library, but now I've commented it out for the same reasons
3700 * added targets 'model-pic16' and 'objects-pic16' to compile the
3702 * added target 'port-specific-objects-pic16' to handle the
3703 generated libraries and copy them into the build/ directory
3704 * added target 'clean-intermediate-pic16' to clean intermediate
3705 files into pic16 directory
3706 * in target 'installdirs' added line to create directory pic16 in
3707 the installation path
3709 * device/include/Makefile.in (version 1.11): in target 'install'
3710 added lines to copy all header files to installation path,
3711 * in target 'installdirs' added line create directory for pic16
3712 headers in the installation path

3727 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3728 option so that it actually works. Made it specific to the z80, since
3729 the gbz80 doesn't have these kinds of I/O ports.
3731 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3733 * device/include/z180.h,

3755 Mainly changes to support compilation of the device libraries
3756 * src/pic16/device.c: stack is allocated via symbol and not
3757 via literal number. The symbol is placed in the corresponding
3758 position of the data ram
3759 * (pic16_dump_section): relocatable and absolute uninitialized
3760 data are now emitted in sorted order to reduce section naming,
3761 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3762 weren't marked as being in the access bank,
3764 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3766 Added portion of GNU PIC Library under the directory
3767 device/include/pic16 and device/lib/pic16. These files
3768 contain the declarations of SFRs for the PIC18Fxx2 devices.
3769 The directory is initialized via configure from toplevel.
3771 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
3773 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

3799 all over. Telling LaTeX to be less strict with word spacing
3800 to better keep the right margin. Changed some notes about
3801 maintainance of the ports in section 3.2.1 - is it OK like this?
3803 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3841 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
3843 * src/pic16/peeph.def: all peepholes with movff are commented out,
3844 because there is a problem in the pcode peep optimizer,
3845 * src/pic16/ralloc.c: the register allocator can now reuse local

3997 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3999 PIC16 port related changes:
4000 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4001 added variable stackPos,
4003 * gen.c: genCall, assignResultValue: added support for
4004 pushing/retrieving function parameters to/from stack,
4005 genFunction,genEndFunction: setup stack frame for the
4007 genAddrOf: will be changed according to bug 863624
4009 * added files genutils.c and genutils.h which contain gen*
4010 debugged and optimised functions extracted from gen.c
4012 * glue.c: added variable 'externs' which holds extern symbols,
4013 pic16emitRegularMap: is modified to properly handle relocatable
4014 symbols under the new scheme,
4015 pic16createInterruptVect: is modified
4016 pic16printPublics: is modified to emit 'global' assembler directives,
4017 added pic16_printExterns to print extern symbols,
4018 pic16glue: initializes stack/frame pointer in the beginning of
4019 the assembly output. Temporary hack, will be corrected later,
4020 because gplink yet does not support stack and SDCC does not
4021 yet support a type of crt0.o object to create the final binary.
4023 * Removed many lines that contain 8051 legacy code.
4024 * The code is finally placed under a 'code' directive.
4025 * Added port specific options.
4027 * _process_pragma: simplified since now we do not need *special*
4028 include file to define SFR registers. But a separate header
4029 will be needed. This will be developed later.
4030 * _pic16_parseOptions: added, parses port specific options:
4031 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4032 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4033 --preplace-udata-with=
4035 * _pic16_setDefaultOptions: modified to initialize section names,
4036 but hack is temporarly out of order since it needs improvement.
4037 * _pic16_genAssemblerPreamble: configuration words are emitted by
4038 their address instead of their name. This part is incomplete and
4039 supports only the 18Fxx2 devices. Other devices will emit an error
4040 during assembly since they do not contain the same set of config
4042 * _pic16_genIVT: is modified,
4044 * pcode.c: added definitions for some hardware registers that are needed
4046 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4047 All PCI entries are updated. Now LFSR is supported.
4048 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4049 * added pic16_newpCodeOpLit2 to support instructions with
4050 two literal arguments
4051 * pic16_pCode2str: corrected code that emits assembler instructions
4052 with two literal operands and those that have an access bit modifier
4053 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4054 this fixes a bug which caused some labels to be lost, when an
4055 assembler directive was added, i.e. banksel,
4056 * pic16_FixRegisterBanking: improved logic that causes the insertion
4058 * InlineFunction: functions that are called once, are not any more
4059 inlined. This can be a port option in the future,
4061 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4063 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4064 hold the corresponding uninitialized symbols,
4065 * pic16_allocProcessorRegister: registers have explicit marked the
4067 * pic16_allocInternalRegister: registers are explicit marked as
4069 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4070 processing list, so bit registers were lost,
4073 * ralloc.h: added field 'accessBank' and original symbol operand
4074 in register definition,
4075 * removed the field isMapped from register definition,
4077 ** Several functions have been removed from various sources:
4078 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4079 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4080 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4081 pic16_assignRelocatableRegisters
4083 ** others have been introduced:
4084 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4085 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4087 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4089 * support/scripts/inc2h.pl: changed definition of BIT_AT
4090 to emit 'sbit at' instead of 'bit at'. This was a request.
4092 PIC16 port related preliminary changes:
4093 * gen.c: prefixed function popRegFromString with
4094 pic16_ and all references to it corrected
4095 * pcode.c: all pic16_pc_* hardware registers prefixed
4096 with underscore (_),
4097 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4098 * ralloc.c: newReg(): when register is REG_SFR then
4099 set address to rIdx,
4100 pic16_allocProcessorRegister(): marks register wasUsed=0
4101 pic16_writeUsedRegs(): added a call to assign processor
4102 registers via pic16_assignFixedRegisters
4104 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4106 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4107 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4108 variables in unused register banks. Also the SSEG is placed
4109 wherever there is enough space for it, and IDATA can be anywhere
4110 in internal RAM. For now compile using -Wl-Y[stack_size].
4111 The mem file is different for this option as well, since it
4112 makes no sense of talking about DSEG lenght.
4114 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4116 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4117 in certain cases, e.g. when ROM assignment, patch provided
4118 from Albert den Haan.

4361 * src/SDCCast.c (decorateType): disabled a transformation I added in
4362 revision 1.188 (access to fields of a structure at an absolute address);
4363 it breaks with bitfields, extern declarations, and gcse analysis.
4364 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4365 could be assigned through a pointer, so don't complain.

5122 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5123 fetching of the pointer
5124 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5125 copied from genNearPointerSet()
5126 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5127 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5141 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5143 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5144 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5145 type for bits was changed. It resulted in bit variables becoming
5146 global, which is not permitted in PIC 14 assembly output.
5148 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5150 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5163 A few small changes that speed up the peephole optimizer.
5167 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5169 Try to make the peephole optimizer smarter by maintaining
5170 an association between the assembly source code and the
5171 iCodes that originated them. Put this information to use
5172 with a new peephole rule condition "notVolatile" so that
5173 the rules can be aggressive yet still safe.
5178 * src/mcs51/peeph.def
5180 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5184 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5185 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5186 if the left or right operand symbols have the accuse flag set.
5188 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5190 Changed the type of the result of the ! (NOT) operator to char;
5191 previously it returned the same type as the source. This allows
5192 us to eliminate all the genFloatNot functions (all of its target
5193 implementations were very buggy) since !float can use the same
5196 * src/SDCCicode.c (ast2iCode): ! returns char

5198 * src/ds390/gen.c (genNot, genNotFloat),
5199 * src/z80/gen.c (genNot, genNotFloat),
5200 * src/pic/gen.c (genNot, genNotFloat),

5205 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5206 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5207 during interrupts. Ensure WSAVE is located at a shared bank address.
5208 2. Fixed page selection in some places
5209 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5210 the registers name strings.
5211 4. Fixed "signed / unsigned compare" compiler warnings.
5212 5. The PIC port manages its own allocation of the general purpose
5213 registers, but makes no attempt to reuse them. As a result when
5214 compiling it soon runs out of general purpose registers. Some
5215 additional code was added to the files pcode.c and device.c to walk
5216 through the function call tree and rename the registers so that they
5226 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5227 genPlus() & genMinus() when the result is the same as left or right

5233 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5235 Made bitfield a distinct type from bit so that bitfields
5236 convert as per ANSI C and bits retain their traditional
5237 boolean style behaviour. Implemented bitfield support in
5245 * src/ds390/gen.c: bit v bitfield split
5246 * src/z80/gen.c: New support for bitfields
5247 * support/regression/tests/bitfields.c: reenabled z80,
5250 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5252 Rules 246.x, 247.x relate to bitfields, the others speed up
5253 access to xdata mapped I/O devices.
5255 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5257 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5259 Cleaned up genPackBits and genUnpackBits and added two helper
5260 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5261 for literal assignments in genPackBits (thanks to Frieder for
5267 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5269 Fixed bug #748310 (pointer to function type mishandled when the
5270 function name is omitted). Also fixed a SIGSEGV when a function
5271 attribute (reentrant, etc) is used on a non-function or on a
5272 function but misplaced before the parameter list.
5274 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5276 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5299 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5301 Made the constant following the "interrupt" keyword optional. If
5302 omitted, the function will not automatically be given an entry
5303 in the interrupt vector table (similar to #pragma NOIV, but
5304 less syntacticly kludgy). The interrupt number is also now
5305 range checked. Also fixed a bug in the high order bit example
5312 * support/Util/SDCCerr.c
5313 * support/Util/SDCCerr.h
5316 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5321 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5323 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5324 be re-activated by defining REDUCE_LITERALS)
5325 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5326 unsigned, but are signed by default
5327 * src/SDCCval.c (constVal): rearranged
5328 * src/SDCCval.c (valMod): preliminary fix
5329 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5372 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5373 * src/SDCCval.c (valDiv, valMod): fixed signdness
5374 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5375 signedness of modulo, left and right shift

5781 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
5782 the regression tests I'm not brave enough to enable 245.b, 245.c
5783 * doc/sdccman.lyx: added latex preamble for hyperref package.
5784 Using pdflatex this will give you a hyperlinked pdf file with
5785 bookmarks. (prepend '%' before /usepackage if this breaks something)

5834 * src/SDCCmain.c: linkOptions is changed to set *,
5835 added if/endif conditional macros to remove options help
5836 messages from optionsTable when a port is not configured, added
5837 support for the PIc16 port in the ports table, when executing
5838 the compiler with no port specified on command line, a default
5839 port is selected with the new macro DEFAULT_PORT which is
5840 defined in port.h, in setDefaultOptions() linkOptions is removed
5841 from initialization assignment, since now it is a set,
5842 parseCmdLine uses setParseWithComma for linkOptions, in
5843 linkEdit() linkOptions are accessed with new function indexSet()
5844 which returns the i'th item of a set variable. See SDCCset.c, in
5845 linkEdit() when calling buildCmdLine(), added linkOptions as
5846 last argument. Now users can pass arguments to gplink via the
5847 -Wl option, main() uses pic16glue() to glue up pic16 programs

5859 * src/pic16/glue.c: commented out some error producing lines
5860 * src/pic16/main.c: __config directives are commented out to stop
5861 gpasm complaining and test the linkage with gplink, _linkCmd and
5862 _asmCmd changed to be more gplink and gpasm friendly
5863 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5864 produced an error when parsed, peep rule 12 is added to utilize
5865 movff, but it is commented out since the pCode does not support
5866 yet a command with 2 address arguments
5868 2003-05-18 <johan AT balder>
5870 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5897 2003-05-11 Borut Razem <borut.razem AT siol.net>
5899 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5900 the path of bin directory, so that PATH is the only env. variable, which has to be set
5901 in case of standard installation.

6986 file with extension .mem. Reports of overlaping stack and small stack
6987 size. If the space for the stack is less than 16 bytes aslink trows a
6990 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6991 the 8051. Option 'y' for memory summary output file.
6993 Changes to sdcc (All the changes are marked with 'JCF'):
6995 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6997 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6998 overlaying area for it (uses RegBankUsed[4]).
7000 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7001 bank zero as used by default. By default aslink locates the stack
7002 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7003 the creation of the .mem file. Delegates the allocation of data area
7004 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7005 the begining of the stack area to aslink.
7007 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7008 glue() in SDCCglue.c creates an area for it.
7010 2002-09-03 Borut Razem <borut.razem AT siol.net>
7011 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7012 sdcc/src/pic/glue.c:
7013 introduced atexit() handler for teporay files removal in case of
7014 errors, assertions, ...
7016 2002-08-29 Borut Razem <borut.razem AT siol.net>
7017 * sdcc/support/cpp2/auto-host_vc_in.h:
7018 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7019 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7020 Maybe there is a similar problem with BORLANDC? It should be checked!
7022 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7023 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7024 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7025 was not executed, and the compiler (cl) launched a warning:
7026 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7028 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7029 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7031 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7032 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7034 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7035 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7036 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7037 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7038 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7039 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7040 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7041 - added Release configuration in VS projects
7042 - review of compiler an linker options
7043 - VC .exe files are generated in bin_vc directory, not to interfere
7044 with binaries generated from other projects (cygwin, mingw, bcc ...)
7046 * sdcc/src/yacc.dsp: added
7048 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7049 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7050 and insert the version number definitions from .version
7052 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7054 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7055 added - genarate auto-host.h using auto-host_vc_in.h as template
7058 removed from CVS, generated automatically
7060 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7061 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7063 2002-08-11 Borut Razem <borut.razem AT siol.net>
7064 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7066 2002-08-10 Borut Razem <borut.razem AT siol.net>
7067 * src/SDCCmain.c (main):
7068 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7069 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7070 The consequence was that some temporary files were not removed.
7073 unification of code in functions tempfilename() and tempfile():
7074 function tempnam() is defined in Visual Studio 6.0 and .NET
7076 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7078 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7079 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7080 - removed compiler command line option /WX: Treats all warnings as errors
7081 - update a list of source files, included into the project
7083 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7084 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7085 changed project type to Generic Project so that can be correcly converted to VS.NET project
7087 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7089 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7091 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7093 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7094 added return 0 statements after assert() to make compiler happy
7096 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7097 added newline in the def file to keep MSC compiler satisfied
7099 * sdcc/src/z80/gen.c:
7100 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7101 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7102 - solved MSC error in function aopDump()
7104 * sdcc_vc.h: define PREFIX as "\\sdcc"
7106 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7107 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7155 Added -p option. Allows port dependent processor to be specified.
7158 Initialized the new field char *Processor field to NULL in all ports
7161 Compiler generated registers for interrupt context saving
7162 were not getting allocated.
7164 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7167 Fixed left shift. Will promote the left side of a left shift
7168 if a) left shifting more than size of operand or b) when assigned
7169 to something size > size of left side
7171 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7279 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7281 * sdcc/src/SDCCloop.c:
7282 Previous fix was not good. basic blocks that have "break" or "return" are
7283 not really partof a loop , but live ranges used in these blocks should
7284 be live thru the entire loop, so set partOfLoop but don't add them to
7287 2002-02-21 <johan AT FRIJA>
7289 * src/SDCCcse.c: fixed bug #514308
7291 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7297 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7299 2002-02-10 Karl Bongers <karl AT turbobit.com>

7316 Karl and Johan start ucsim XA support. Most dissassembly working,
7317 about 75% emulation done(plenty of work remaining).
7319 * sim/ucsim/z80.src:
7320 Add Z80 support to ucsim, add test-ucz80 regression test,
7321 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
