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

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

3716 loaded with the linker search paths (-L arguments) and the libraries
3717 to be linked with the current source (-l arguments). Changes
3718 currently will affect only the pic16 port.
3719 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3720 include path the port specific paths and port specific libraries,
3721 * gplink command now contains the $3 argument,
3722 * src/pic16/device.h,

3739 Documenting changes from previous commits.
3740 * configure.in (version 1.56),
3741 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3742 when generating output files to configure the pic16 library,
3743 but now I've commented it out, since gputils aren't installed in the
3744 SF compile farm, so library won't compile
3746 * device/lib/Makefile.in (version 1.56): initially I've added in
3747 target 'all' the prerequestive 'model-pic16' so it compiled the
3748 pic16 library, but now I've commented it out for the same reasons
3750 * added targets 'model-pic16' and 'objects-pic16' to compile the
3752 * added target 'port-specific-objects-pic16' to handle the
3753 generated libraries and copy them into the build/ directory
3754 * added target 'clean-intermediate-pic16' to clean intermediate
3755 files into pic16 directory
3756 * in target 'installdirs' added line to create directory pic16 in

4065 pic16createInterruptVect: is modified
4066 pic16printPublics: is modified to emit 'global' assembler directives,
4067 added pic16_printExterns to print extern symbols,
4068 pic16glue: initializes stack/frame pointer in the beginning of
4069 the assembly output. Temporary hack, will be corrected later,
4070 because gplink yet does not support stack and SDCC does not
4071 yet support a type of crt0.o object to create the final binary.
4073 * Removed many lines that contain 8051 legacy code.
4074 * The code is finally placed under a 'code' directive.
4075 * Added port specific options.
4077 * _process_pragma: simplified since now we do not need *special*
4078 include file to define SFR registers. But a separate header
4079 will be needed. This will be developed later.
4080 * _pic16_parseOptions: added, parses port specific options:
4081 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4082 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4083 --preplace-udata-with=
4085 * _pic16_setDefaultOptions: modified to initialize section names,
4086 but hack is temporarly out of order since it needs improvement.
4087 * _pic16_genAssemblerPreamble: configuration words are emitted by
4088 their address instead of their name. This part is incomplete and
4089 supports only the 18Fxx2 devices. Other devices will emit an error
4090 during assembly since they do not contain the same set of config
4092 * _pic16_genIVT: is modified,
4094 * pcode.c: added definitions for some hardware registers that are needed
4096 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4097 All PCI entries are updated. Now LFSR is supported.
4098 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4099 * added pic16_newpCodeOpLit2 to support instructions with
4100 two literal arguments
4101 * pic16_pCode2str: corrected code that emits assembler instructions
4102 with two literal operands and those that have an access bit modifier
4103 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4104 this fixes a bug which caused some labels to be lost, when an
4105 assembler directive was added, i.e. banksel,
4106 * pic16_FixRegisterBanking: improved logic that causes the insertion
4108 * InlineFunction: functions that are called once, are not any more
4109 inlined. This can be a port option in the future,
4111 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4113 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4114 hold the corresponding uninitialized symbols,
4115 * pic16_allocProcessorRegister: registers have explicit marked the
4117 * pic16_allocInternalRegister: registers are explicit marked as
4119 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4120 processing list, so bit registers were lost,
4123 * ralloc.h: added field 'accessBank' and original symbol operand
4124 in register definition,
4125 * removed the field isMapped from register definition,
4127 ** Several functions have been removed from various sources:
4128 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4129 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4130 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4131 pic16_assignRelocatableRegisters
4133 ** others have been introduced:
4134 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4135 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4137 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4139 * support/scripts/inc2h.pl: changed definition of BIT_AT
4140 to emit 'sbit at' instead of 'bit at'. This was a request.
4142 PIC16 port related preliminary changes:
4143 * gen.c: prefixed function popRegFromString with
4144 pic16_ and all references to it corrected
4145 * pcode.c: all pic16_pc_* hardware registers prefixed
4146 with underscore (_),
4147 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4148 * ralloc.c: newReg(): when register is REG_SFR then
4149 set address to rIdx,
4150 pic16_allocProcessorRegister(): marks register wasUsed=0
4151 pic16_writeUsedRegs(): added a call to assign processor
4152 registers via pic16_assignFixedRegisters
4154 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4156 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4157 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4158 variables in unused register banks. Also the SSEG is placed
4159 wherever there is enough space for it, and IDATA can be anywhere
4160 in internal RAM. For now compile using -Wl-Y[stack_size].
4161 The mem file is different for this option as well, since it
4162 makes no sense of talking about DSEG lenght.
4164 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4166 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4167 in certain cases, e.g. when ROM assignment, patch provided
4168 from Albert den Haan.

4409 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4411 * src/SDCCast.c (decorateType): disabled a transformation I added in
4412 revision 1.188 (access to fields of a structure at an absolute address);
4413 it breaks with bitfields, extern declarations, and gcse analysis.
4414 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4415 could be assigned through a pointer, so don't complain.
4416 * src/SDCCast.c (astErrors),
4418 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4520 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4521 uninitialized variables) for the mcs51. Set environment variable
4522 SDCC_GENRAMCLEAR to test.
4523 xdata initialization slightly shorter
4525 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5172 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5173 fetching of the pointer
5174 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5175 copied from genNearPointerSet()
5176 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5177 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5193 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5194 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5195 type for bits was changed. It resulted in bit variables becoming
5196 global, which is not permitted in PIC 14 assembly output.
5198 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5200 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5213 A few small changes that speed up the peephole optimizer.
5217 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5219 Try to make the peephole optimizer smarter by maintaining
5220 an association between the assembly source code and the
5221 iCodes that originated them. Put this information to use
5222 with a new peephole rule condition "notVolatile" so that
5223 the rules can be aggressive yet still safe.
5228 * src/mcs51/peeph.def
5230 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5234 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5235 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5236 if the left or right operand symbols have the accuse flag set.
5238 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5240 Changed the type of the result of the ! (NOT) operator to char;
5241 previously it returned the same type as the source. This allows
5242 us to eliminate all the genFloatNot functions (all of its target
5243 implementations were very buggy) since !float can use the same
5246 * src/SDCCicode.c (ast2iCode): ! returns char

5255 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5256 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5257 during interrupts. Ensure WSAVE is located at a shared bank address.
5258 2. Fixed page selection in some places
5259 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5260 the registers name strings.
5261 4. Fixed "signed / unsigned compare" compiler warnings.
5262 5. The PIC port manages its own allocation of the general purpose
5263 registers, but makes no attempt to reuse them. As a result when
5264 compiling it soon runs out of general purpose registers. Some
5265 additional code was added to the files pcode.c and device.c to walk
5266 through the function call tree and rename the registers so that they
5276 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5277 genPlus() & genMinus() when the result is the same as left or right

5283 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5285 Made bitfield a distinct type from bit so that bitfields
5286 convert as per ANSI C and bits retain their traditional
5287 boolean style behaviour. Implemented bitfield support in
5295 * src/ds390/gen.c: bit v bitfield split
5296 * src/z80/gen.c: New support for bitfields
5297 * support/regression/tests/bitfields.c: reenabled z80,
5300 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5302 Rules 246.x, 247.x relate to bitfields, the others speed up
5303 access to xdata mapped I/O devices.
5305 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5307 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5309 Cleaned up genPackBits and genUnpackBits and added two helper
5310 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5311 for literal assignments in genPackBits (thanks to Frieder for
5317 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5319 Fixed bug #748310 (pointer to function type mishandled when the
5320 function name is omitted). Also fixed a SIGSEGV when a function
5321 attribute (reentrant, etc) is used on a non-function or on a
5322 function but misplaced before the parameter list.
5324 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5326 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5327 * support/Util/SDCCerr.h,
5328 * support/Util/SDCCerr.c: Added func attr misuse error msg
5330 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5332 Fixed bug #787649 by anonymous
5333 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

5349 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5351 Made the constant following the "interrupt" keyword optional. If
5352 omitted, the function will not automatically be given an entry
5353 in the interrupt vector table (similar to #pragma NOIV, but
5354 less syntacticly kludgy). The interrupt number is also now
5355 range checked. Also fixed a bug in the high order bit example

5363 * support/Util/SDCCerr.h
5366 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5368 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5369 * src/SDCCicode.c (operandOperation): rewritten some ops
5370 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5371 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5373 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5374 be re-activated by defining REDUCE_LITERALS)
5375 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5376 unsigned, but are signed by default
5377 * src/SDCCval.c (constVal): rearranged
5378 * src/SDCCval.c (valMod): preliminary fix
5379 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5421 constants are unsigned; added recognition of "u" flag for unsigned
5422 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5423 * src/SDCCval.c (valDiv, valMod): fixed signdness
5424 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5425 signedness of modulo, left and right shift

5885 added if/endif conditional macros to remove options help
5886 messages from optionsTable when a port is not configured, added
5887 support for the PIc16 port in the ports table, when executing
5888 the compiler with no port specified on command line, a default
5889 port is selected with the new macro DEFAULT_PORT which is
5890 defined in port.h, in setDefaultOptions() linkOptions is removed
5891 from initialization assignment, since now it is a set,
5892 parseCmdLine uses setParseWithComma for linkOptions, in
5893 linkEdit() linkOptions are accessed with new function indexSet()
5894 which returns the i'th item of a set variable. See SDCCset.c, in
5895 linkEdit() when calling buildCmdLine(), added linkOptions as
5896 last argument. Now users can pass arguments to gplink via the
5897 -Wl option, main() uses pic16glue() to glue up pic16 programs

5911 gpasm complaining and test the linkage with gplink, _linkCmd and
5912 _asmCmd changed to be more gplink and gpasm friendly
5913 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5914 produced an error when parsed, peep rule 12 is added to utilize
5915 movff, but it is commented out since the pCode does not support
5916 yet a command with 2 address arguments
5918 2003-05-18 <johan AT balder>
5920 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5947 2003-05-11 Borut Razem <borut.razem AT siol.net>
5949 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5950 the path of bin directory, so that PATH is the only env. variable, which has to be set
5951 in case of standard installation.

6984 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6985 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6986 following files to include the previous two files: aslink.dsp,
6987 Makefile.aslink, Makefile.bcc, and Makefile.in.
6989 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6990 .adb instead of .cdb
6992 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6994 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6995 value from option --iram-size.
6997 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6999 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7002 2002-09-18 <wiml AT hhhh.org>
7004 * SDCClrange.h: exposed setFromRange() and setToRange()
7005 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7006 packRegsForAccUse() (bug 542397)
7007 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7008 multiple times and emitting the fetch operations more than once
7009 added aopGetUsesAcc() function to allow binary operators to
7010 fetch their operands in the correct order; made genMinus() emit
7011 compact code for X = LITERAL - Y
7013 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7014 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7015 sprintf() in line 1267.
7017 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7018 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7021 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7022 Changes to aslink (All the changes are marked with 'JCF'):
7024 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7027 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7028 area BSEG. Also moves, if possible, the DATA area down into the internal
7029 ram so more space is available.
7031 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7034 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7035 not bytes. Function summary() which creates a memory usage summary
7036 file with extension .mem. Reports of overlaping stack and small stack
7037 size. If the space for the stack is less than 16 bytes aslink trows a
7040 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7041 the 8051. Option 'y' for memory summary output file.
7043 Changes to sdcc (All the changes are marked with 'JCF'):
7045 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7047 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7048 overlaying area for it (uses RegBankUsed[4]).
7050 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7051 bank zero as used by default. By default aslink locates the stack
7052 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7053 the creation of the .mem file. Delegates the allocation of data area
7054 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7055 the begining of the stack area to aslink.
7057 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7058 glue() in SDCCglue.c creates an area for it.
7060 2002-09-03 Borut Razem <borut.razem AT siol.net>
7061 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7062 sdcc/src/pic/glue.c:
7063 introduced atexit() handler for teporay files removal in case of
7064 errors, assertions, ...
7066 2002-08-29 Borut Razem <borut.razem AT siol.net>
7067 * sdcc/support/cpp2/auto-host_vc_in.h:
7068 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7069 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7070 Maybe there is a similar problem with BORLANDC? It should be checked!
7072 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7073 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7074 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7075 was not executed, and the compiler (cl) launched a warning:
7076 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7078 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7079 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7081 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7082 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7084 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7085 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7086 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7087 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7088 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7089 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7090 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7091 - added Release configuration in VS projects
7092 - review of compiler an linker options
7093 - VC .exe files are generated in bin_vc directory, not to interfere
7094 with binaries generated from other projects (cygwin, mingw, bcc ...)
7096 * sdcc/src/yacc.dsp: added
7098 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7099 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7100 and insert the version number definitions from .version
7102 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7104 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7105 added - genarate auto-host.h using auto-host_vc_in.h as template
7108 removed from CVS, generated automatically
7110 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7111 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7113 2002-08-11 Borut Razem <borut.razem AT siol.net>
7114 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7116 2002-08-10 Borut Razem <borut.razem AT siol.net>
7117 * src/SDCCmain.c (main):
7118 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7119 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7120 The consequence was that some temporary files were not removed.
7123 unification of code in functions tempfilename() and tempfile():
7124 function tempnam() is defined in Visual Studio 6.0 and .NET
7126 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7128 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7129 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7130 - removed compiler command line option /WX: Treats all warnings as errors
7131 - update a list of source files, included into the project
7133 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7134 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7135 changed project type to Generic Project so that can be correcly converted to VS.NET project
7137 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7139 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7141 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7143 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7144 added return 0 statements after assert() to make compiler happy
7146 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7147 added newline in the def file to keep MSC compiler satisfied
7149 * sdcc/src/z80/gen.c:
7150 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7151 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7152 - solved MSC error in function aopDump()
7154 * sdcc_vc.h: define PREFIX as "\\sdcc"
7156 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7157 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7159 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7160 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7161 - Rewrote the register banking algorithm.
7162 - Added pCode live-range analysis to registers (for now, only non-used and
7163 singly-used registers optimized away)
7165 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7167 * 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.

7194 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7196 2002-03-28 Johan Knol <johan AT balder>
7198 * src/SDCCval.c: fixed bug #532436
7200 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7202 Added "char *Processor" field to the port structure.
7205 Added -p option. Allows port dependent processor to be specified.
7208 Initialized the new field char *Processor field to NULL in all ports
7211 Compiler generated registers for interrupt context saving
7212 were not getting allocated.
7214 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7217 Fixed left shift. Will promote the left side of a left shift
7218 if a) left shifting more than size of operand or b) when assigned
7219 to something size > size of left side
7221 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7223 tons of changes. Register allocation has been
7224 rewritten. Added customization for the various PICs. Flow
7225 analysis is restructured. ...
7231 Added. device.c is a PIC port hack to accomodate variations
7234 2002-03-13 Michael Hope <michaelh AT vroom>
7236 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7329 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7331 * sdcc/src/SDCCloop.c:
7332 Previous fix was not good. basic blocks that have "break" or "return" are
7333 not really partof a loop , but live ranges used in these blocks should
7334 be live thru the entire loop, so set partOfLoop but don't add them to
7337 2002-02-21 <johan AT FRIJA>
7339 * src/SDCCcse.c: fixed bug #514308
7341 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7344 Fixed BUG #519583. If a conditional block ended in a return/break
7345 statement inside a loop, it was not being considered part of the loop.
7347 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7349 2002-02-10 Karl Bongers <karl AT turbobit.com>
7352 Fixed up SDCDB debugger somewhat. Updated debugger/README
7353 with lots of comments and notes.
7355 * device/examples/test2.c:
7356 Fix bug, "red" variable not being initialized(compiler complained).

7362 * sim/ucsim/cmd.src/cmdset.cc:
7363 Took out debug printfs in ucsim "next" command.
7366 Karl and Johan start ucsim XA support. Most dissassembly working,
7367 about 75% emulation done(plenty of work remaining).
7369 * sim/ucsim/z80.src:
7370 Add Z80 support to ucsim, add test-ucz80 regression test,
7371 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

7407 set preprocessor defines (depending on options)
7409 * src/SDCCicode.c, src/SDCCicode.h:
7410 changes made to handle multiple sends & receives
7413 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
