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

671 * added libc directory. The current version of LibC contains string
672 functions, ctype functions and macros and some functions of the
673 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
674 be extensively tested in the future. Standard disclaimer here.

688 * (genCmp): experimental code for new genCmp which uses PIC18's
689 special compare&skip instructions. Initial tests fail some times
690 with variables grater than 1 byte in size, so new code is disabled,
691 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
693 * (genCast): began a fix to optimize the casting of a bit to another
694 bit, now assigning a bitfield to another bitfield will fail, sorry,

3717 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3719 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3720 loaded with the linker search paths (-L arguments) and the libraries
3721 to be linked with the current source (-l arguments). Changes
3722 currently will affect only the pic16 port.
3723 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3724 include path the port specific paths and port specific libraries,
3725 * gplink command now contains the $3 argument,
3726 * src/pic16/device.h,
3727 * src/pic16/device.c,: structure PIC_device is made public and
3728 renamed to PIC16_device, the same for variable Pics which is renamed

3743 Documenting changes from previous commits.
3744 * configure.in (version 1.56),
3745 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3746 when generating output files to configure the pic16 library,
3747 but now I've commented it out, since gputils aren't installed in the
3748 SF compile farm, so library won't compile
3750 * device/lib/Makefile.in (version 1.56): initially I've added in
3751 target 'all' the prerequestive 'model-pic16' so it compiled the
3752 pic16 library, but now I've commented it out for the same reasons
3754 * added targets 'model-pic16' and 'objects-pic16' to compile the
3756 * added target 'port-specific-objects-pic16' to handle the
3757 generated libraries and copy them into the build/ directory
3758 * added target 'clean-intermediate-pic16' to clean intermediate
3759 files into pic16 directory
3760 * in target 'installdirs' added line to create directory pic16 in

4066 * glue.c: added variable 'externs' which holds extern symbols,
4067 pic16emitRegularMap: is modified to properly handle relocatable
4068 symbols under the new scheme,
4069 pic16createInterruptVect: is modified
4070 pic16printPublics: is modified to emit 'global' assembler directives,
4071 added pic16_printExterns to print extern symbols,
4072 pic16glue: initializes stack/frame pointer in the beginning of
4073 the assembly output. Temporary hack, will be corrected later,
4074 because gplink yet does not support stack and SDCC does not
4075 yet support a type of crt0.o object to create the final binary.
4077 * Removed many lines that contain 8051 legacy code.
4078 * The code is finally placed under a 'code' directive.
4079 * Added port specific options.
4081 * _process_pragma: simplified since now we do not need *special*
4082 include file to define SFR registers. But a separate header
4083 will be needed. This will be developed later.
4084 * _pic16_parseOptions: added, parses port specific options:
4085 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4086 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4087 --preplace-udata-with=
4089 * _pic16_setDefaultOptions: modified to initialize section names,
4090 but hack is temporarly out of order since it needs improvement.
4091 * _pic16_genAssemblerPreamble: configuration words are emitted by
4092 their address instead of their name. This part is incomplete and
4093 supports only the 18Fxx2 devices. Other devices will emit an error
4094 during assembly since they do not contain the same set of config
4096 * _pic16_genIVT: is modified,
4098 * pcode.c: added definitions for some hardware registers that are needed
4100 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4101 All PCI entries are updated. Now LFSR is supported.
4102 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4103 * added pic16_newpCodeOpLit2 to support instructions with
4104 two literal arguments
4105 * pic16_pCode2str: corrected code that emits assembler instructions
4106 with two literal operands and those that have an access bit modifier
4107 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4108 this fixes a bug which caused some labels to be lost, when an
4109 assembler directive was added, i.e. banksel,
4110 * pic16_FixRegisterBanking: improved logic that causes the insertion
4112 * InlineFunction: functions that are called once, are not any more
4113 inlined. This can be a port option in the future,
4115 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4117 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4118 hold the corresponding uninitialized symbols,
4119 * pic16_allocProcessorRegister: registers have explicit marked the
4121 * pic16_allocInternalRegister: registers are explicit marked as
4123 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4124 processing list, so bit registers were lost,
4127 * ralloc.h: added field 'accessBank' and original symbol operand
4128 in register definition,
4129 * removed the field isMapped from register definition,
4131 ** Several functions have been removed from various sources:
4132 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4133 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4134 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4135 pic16_assignRelocatableRegisters
4137 ** others have been introduced:
4138 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4139 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4141 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4143 * support/scripts/inc2h.pl: changed definition of BIT_AT
4144 to emit 'sbit at' instead of 'bit at'. This was a request.
4146 PIC16 port related preliminary changes:
4147 * gen.c: prefixed function popRegFromString with
4148 pic16_ and all references to it corrected
4149 * pcode.c: all pic16_pc_* hardware registers prefixed
4150 with underscore (_),
4151 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4152 * ralloc.c: newReg(): when register is REG_SFR then
4153 set address to rIdx,
4154 pic16_allocProcessorRegister(): marks register wasUsed=0
4155 pic16_writeUsedRegs(): added a call to assign processor
4156 registers via pic16_assignFixedRegisters
4158 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4160 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4161 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4162 variables in unused register banks. Also the SSEG is placed
4163 wherever there is enough space for it, and IDATA can be anywhere
4164 in internal RAM. For now compile using -Wl-Y[stack_size].
4165 The mem file is different for this option as well, since it
4166 makes no sense of talking about DSEG lenght.
4168 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4170 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4171 in certain cases, e.g. when ROM assignment, patch provided
4172 from Albert den Haan.

4317 * src/mcs51/peephole.def,
4318 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4330 multiply defined with mismatching "at" address.
4332 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4413 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4415 * src/SDCCast.c (decorateType): disabled a transformation I added in
4416 revision 1.188 (access to fields of a structure at an absolute address);
4417 it breaks with bitfields, extern declarations, and gcse analysis.
4418 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4419 could be assigned through a pointer, so don't complain.
4420 * src/SDCCast.c (astErrors),
4422 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4524 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4525 uninitialized variables) for the mcs51. Set environment variable
4526 SDCC_GENRAMCLEAR to test.

5176 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5177 fetching of the pointer
5178 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5179 copied from genNearPointerSet()
5180 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5181 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5197 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5198 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5199 type for bits was changed. It resulted in bit variables becoming
5200 global, which is not permitted in PIC 14 assembly output.
5202 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5204 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5217 A few small changes that speed up the peephole optimizer.
5221 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5223 Try to make the peephole optimizer smarter by maintaining
5224 an association between the assembly source code and the
5225 iCodes that originated them. Put this information to use
5226 with a new peephole rule condition "notVolatile" so that
5227 the rules can be aggressive yet still safe.
5232 * src/mcs51/peeph.def
5234 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5238 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5239 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5240 if the left or right operand symbols have the accuse flag set.
5242 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5244 Changed the type of the result of the ! (NOT) operator to char;
5245 previously it returned the same type as the source. This allows
5246 us to eliminate all the genFloatNot functions (all of its target
5247 implementations were very buggy) since !float can use the same

5259 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5260 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5261 during interrupts. Ensure WSAVE is located at a shared bank address.
5262 2. Fixed page selection in some places
5263 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5264 the registers name strings.
5265 4. Fixed "signed / unsigned compare" compiler warnings.
5266 5. The PIC port manages its own allocation of the general purpose
5267 registers, but makes no attempt to reuse them. As a result when
5268 compiling it soon runs out of general purpose registers. Some
5269 additional code was added to the files pcode.c and device.c to walk
5270 through the function call tree and rename the registers so that they
5280 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5287 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5289 Made bitfield a distinct type from bit so that bitfields
5290 convert as per ANSI C and bits retain their traditional
5291 boolean style behaviour. Implemented bitfield support in
5299 * src/ds390/gen.c: bit v bitfield split
5300 * src/z80/gen.c: New support for bitfields
5301 * support/regression/tests/bitfields.c: reenabled z80,
5304 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5306 Rules 246.x, 247.x relate to bitfields, the others speed up
5307 access to xdata mapped I/O devices.
5309 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5311 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5313 Cleaned up genPackBits and genUnpackBits and added two helper
5314 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5315 for literal assignments in genPackBits (thanks to Frieder for
5321 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5323 Fixed bug #748310 (pointer to function type mishandled when the
5324 function name is omitted). Also fixed a SIGSEGV when a function
5325 attribute (reentrant, etc) is used on a non-function or on a
5326 function but misplaced before the parameter list.
5328 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5330 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5331 * support/Util/SDCCerr.h,
5332 * support/Util/SDCCerr.c: Added func attr misuse error msg

5353 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5355 Made the constant following the "interrupt" keyword optional. If
5356 omitted, the function will not automatically be given an entry
5357 in the interrupt vector table (similar to #pragma NOIV, but
5358 less syntacticly kludgy). The interrupt number is also now
5359 range checked. Also fixed a bug in the high order bit example

5373 * src/SDCCicode.c (operandOperation): rewritten some ops
5374 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5375 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5377 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5378 be re-activated by defining REDUCE_LITERALS)
5379 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5380 unsigned, but are signed by default
5381 * src/SDCCval.c (constVal): rearranged
5382 * src/SDCCval.c (valMod): preliminary fix
5383 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5425 constants are unsigned; added recognition of "u" flag for unsigned
5426 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5427 * src/SDCCval.c (valDiv, valMod): fixed signdness
5428 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5429 signedness of modulo, left and right shift

5888 * src/SDCCmain.c: linkOptions is changed to set *,
5889 added if/endif conditional macros to remove options help
5890 messages from optionsTable when a port is not configured, added
5891 support for the PIc16 port in the ports table, when executing
5892 the compiler with no port specified on command line, a default
5893 port is selected with the new macro DEFAULT_PORT which is
5894 defined in port.h, in setDefaultOptions() linkOptions is removed
5895 from initialization assignment, since now it is a set,
5896 parseCmdLine uses setParseWithComma for linkOptions, in
5897 linkEdit() linkOptions are accessed with new function indexSet()
5898 which returns the i'th item of a set variable. See SDCCset.c, in
5899 linkEdit() when calling buildCmdLine(), added linkOptions as
5900 last argument. Now users can pass arguments to gplink via the
5901 -Wl option, main() uses pic16glue() to glue up pic16 programs

5915 gpasm complaining and test the linkage with gplink, _linkCmd and
5916 _asmCmd changed to be more gplink and gpasm friendly
5917 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5918 produced an error when parsed, peep rule 12 is added to utilize
5919 movff, but it is commented out since the pCode does not support
5920 yet a command with 2 address arguments
5922 2003-05-18 <johan AT balder>
5924 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5951 2003-05-11 Borut Razem <borut.razem AT siol.net>
5953 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5954 the path of bin directory, so that PATH is the only env. variable, which has to be set
5955 in case of standard installation.

6983 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6985 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6987 * in \sdcc\as\mcs51\ changed these files in order to create an
6988 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6989 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6990 following files to include the previous two files: aslink.dsp,
6991 Makefile.aslink, Makefile.bcc, and Makefile.in.
6993 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6994 .adb instead of .cdb
6996 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6998 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6999 value from option --iram-size.
7001 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7003 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7006 2002-09-18 <wiml AT hhhh.org>
7008 * SDCClrange.h: exposed setFromRange() and setToRange()
7009 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7010 packRegsForAccUse() (bug 542397)
7011 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7012 multiple times and emitting the fetch operations more than once
7013 added aopGetUsesAcc() function to allow binary operators to
7014 fetch their operands in the correct order; made genMinus() emit
7015 compact code for X = LITERAL - Y
7017 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7018 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7019 sprintf() in line 1267.
7021 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7022 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7025 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7026 Changes to aslink (All the changes are marked with 'JCF'):
7028 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7031 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7032 area BSEG. Also moves, if possible, the DATA area down into the internal
7033 ram so more space is available.
7035 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7038 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7039 not bytes. Function summary() which creates a memory usage summary
7040 file with extension .mem. Reports of overlaping stack and small stack
7041 size. If the space for the stack is less than 16 bytes aslink trows a
7044 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7045 the 8051. Option 'y' for memory summary output file.
7047 Changes to sdcc (All the changes are marked with 'JCF'):
7049 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7051 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7052 overlaying area for it (uses RegBankUsed[4]).
7054 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7055 bank zero as used by default. By default aslink locates the stack
7056 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7057 the creation of the .mem file. Delegates the allocation of data area
7058 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7059 the begining of the stack area to aslink.
7061 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7062 glue() in SDCCglue.c creates an area for it.
7064 2002-09-03 Borut Razem <borut.razem AT siol.net>
7065 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7066 sdcc/src/pic/glue.c:
7067 introduced atexit() handler for teporay files removal in case of
7068 errors, assertions, ...
7070 2002-08-29 Borut Razem <borut.razem AT siol.net>
7071 * sdcc/support/cpp2/auto-host_vc_in.h:
7072 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7073 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7074 Maybe there is a similar problem with BORLANDC? It should be checked!
7076 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7077 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7078 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7079 was not executed, and the compiler (cl) launched a warning:
7080 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7082 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7083 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7085 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7086 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7088 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7089 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7090 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7091 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7092 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7093 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7094 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7095 - added Release configuration in VS projects
7096 - review of compiler an linker options
7097 - VC .exe files are generated in bin_vc directory, not to interfere
7098 with binaries generated from other projects (cygwin, mingw, bcc ...)
7100 * sdcc/src/yacc.dsp: added
7102 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7103 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7104 and insert the version number definitions from .version
7106 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7108 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7109 added - genarate auto-host.h using auto-host_vc_in.h as template
7112 removed from CVS, generated automatically
7114 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7115 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7117 2002-08-11 Borut Razem <borut.razem AT siol.net>
7118 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7120 2002-08-10 Borut Razem <borut.razem AT siol.net>
7121 * src/SDCCmain.c (main):
7122 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7123 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7124 The consequence was that some temporary files were not removed.
7127 unification of code in functions tempfilename() and tempfile():
7128 function tempnam() is defined in Visual Studio 6.0 and .NET
7130 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7132 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7133 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7134 - removed compiler command line option /WX: Treats all warnings as errors
7135 - update a list of source files, included into the project
7137 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7138 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7139 changed project type to Generic Project so that can be correcly converted to VS.NET project
7141 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7143 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7145 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7147 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7148 added return 0 statements after assert() to make compiler happy
7150 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7151 added newline in the def file to keep MSC compiler satisfied
7153 * sdcc/src/z80/gen.c:
7154 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7155 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7156 - solved MSC error in function aopDump()
7158 * sdcc_vc.h: define PREFIX as "\\sdcc"
7160 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7161 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7163 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7164 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7165 - Rewrote the register banking algorithm.
7166 - Added pCode live-range analysis to registers (for now, only non-used and
7167 singly-used registers optimized away)
7169 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7171 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
7173 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7174 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7176 2002-04-22 Michael Hope <michaelh AT vroom>

7198 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7200 2002-03-28 Johan Knol <johan AT balder>
7202 * src/SDCCval.c: fixed bug #532436
7204 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7206 Added "char *Processor" field to the port structure.
7209 Added -p option. Allows port dependent processor to be specified.
7212 Initialized the new field char *Processor field to NULL in all ports
7215 Compiler generated registers for interrupt context saving
7216 were not getting allocated.
7218 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7221 Fixed left shift. Will promote the left side of a left shift
7222 if a) left shifting more than size of operand or b) when assigned
7223 to something size > size of left side
7225 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7227 tons of changes. Register allocation has been
7228 rewritten. Added customization for the various PICs. Flow
7229 analysis is restructured. ...
7235 Added. device.c is a PIC port hack to accomodate variations
7238 2002-03-13 Michael Hope <michaelh AT vroom>
7240 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7333 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7335 * sdcc/src/SDCCloop.c:
7336 Previous fix was not good. basic blocks that have "break" or "return" are
7337 not really partof a loop , but live ranges used in these blocks should
7338 be live thru the entire loop, so set partOfLoop but don't add them to
7341 2002-02-21 <johan AT FRIJA>
7343 * src/SDCCcse.c: fixed bug #514308
7345 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7348 Fixed BUG #519583. If a conditional block ended in a return/break
7349 statement inside a loop, it was not being considered part of the loop.
7351 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7353 2002-02-10 Karl Bongers <karl AT turbobit.com>
7356 Fixed up SDCDB debugger somewhat. Updated debugger/README
7357 with lots of comments and notes.
7359 * device/examples/test2.c:
7360 Fix bug, "red" variable not being initialized(compiler complained).
7362 * device/examples/Makefile, examples/test3.c:
7363 Add Makefile in device/examples folder, compiles test3.c
7364 for use as a multiple module SDCDB test case.
7366 * sim/ucsim/cmd.src/cmdset.cc:
7367 Took out debug printfs in ucsim "next" command.
7370 Karl and Johan start ucsim XA support. Most dissassembly working,
7371 about 75% emulation done(plenty of work remaining).
7373 * sim/ucsim/z80.src:
7374 Add Z80 support to ucsim, add test-ucz80 regression test,
7375 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

7411 set preprocessor defines (depending on options)
7413 * src/SDCCicode.c, src/SDCCicode.h:
7414 changes made to handle multiple sends & receives
7417 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
