678 functions, ctype functions and macros and some functions of the
679 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
680 be extensively tested in the future. Standard disclaimer here.

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

3725 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3726 loaded with the linker search paths (-L arguments) and the libraries
3727 to be linked with the current source (-l arguments). Changes
3728 currently will affect only the pic16 port.
3729 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3730 include path the port specific paths and port specific libraries,
3731 * gplink command now contains the $3 argument,
3732 * src/pic16/device.h,

3749 Documenting changes from previous commits.
3750 * configure.in (version 1.56),
3751 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3752 when generating output files to configure the pic16 library,
3753 but now I've commented it out, since gputils aren't installed in the
3754 SF compile farm, so library won't compile
3756 * device/lib/Makefile.in (version 1.56): initially I've added in
3757 target 'all' the prerequestive 'model-pic16' so it compiled the
3758 pic16 library, but now I've commented it out for the same reasons
3760 * added targets 'model-pic16' and 'objects-pic16' to compile the
3762 * added target 'port-specific-objects-pic16' to handle the
3763 generated libraries and copy them into the build/ directory
3764 * added target 'clean-intermediate-pic16' to clean intermediate
3765 files into pic16 directory
3766 * in target 'installdirs' added line to create directory pic16 in

4063 * gen.c: genCall, assignResultValue: added support for
4064 pushing/retrieving function parameters to/from stack,
4065 genFunction,genEndFunction: setup stack frame for the
4067 genAddrOf: will be changed according to bug 863624
4069 * added files genutils.c and genutils.h which contain gen*
4070 debugged and optimised functions extracted from gen.c
4072 * glue.c: added variable 'externs' which holds extern symbols,
4073 pic16emitRegularMap: is modified to properly handle relocatable
4074 symbols under the new scheme,
4075 pic16createInterruptVect: is modified
4076 pic16printPublics: is modified to emit 'global' assembler directives,
4077 added pic16_printExterns to print extern symbols,
4078 pic16glue: initializes stack/frame pointer in the beginning of
4079 the assembly output. Temporary hack, will be corrected later,
4080 because gplink yet does not support stack and SDCC does not
4081 yet support a type of crt0.o object to create the final binary.
4083 * Removed many lines that contain 8051 legacy code.
4084 * The code is finally placed under a 'code' directive.
4085 * Added port specific options.
4087 * _process_pragma: simplified since now we do not need *special*
4088 include file to define SFR registers. But a separate header
4089 will be needed. This will be developed later.
4090 * _pic16_parseOptions: added, parses port specific options:
4091 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4092 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4093 --preplace-udata-with=
4095 * _pic16_setDefaultOptions: modified to initialize section names,
4096 but hack is temporarly out of order since it needs improvement.
4097 * _pic16_genAssemblerPreamble: configuration words are emitted by
4098 their address instead of their name. This part is incomplete and
4099 supports only the 18Fxx2 devices. Other devices will emit an error
4100 during assembly since they do not contain the same set of config
4102 * _pic16_genIVT: is modified,
4104 * pcode.c: added definitions for some hardware registers that are needed
4106 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4107 All PCI entries are updated. Now LFSR is supported.
4108 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4109 * added pic16_newpCodeOpLit2 to support instructions with
4110 two literal arguments
4111 * pic16_pCode2str: corrected code that emits assembler instructions
4112 with two literal operands and those that have an access bit modifier
4113 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4114 this fixes a bug which caused some labels to be lost, when an
4115 assembler directive was added, i.e. banksel,
4116 * pic16_FixRegisterBanking: improved logic that causes the insertion
4118 * InlineFunction: functions that are called once, are not any more
4119 inlined. This can be a port option in the future,
4121 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4123 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4124 hold the corresponding uninitialized symbols,
4125 * pic16_allocProcessorRegister: registers have explicit marked the
4127 * pic16_allocInternalRegister: registers are explicit marked as
4129 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4130 processing list, so bit registers were lost,
4133 * ralloc.h: added field 'accessBank' and original symbol operand
4134 in register definition,
4135 * removed the field isMapped from register definition,
4137 ** Several functions have been removed from various sources:
4138 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4139 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4140 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4141 pic16_assignRelocatableRegisters
4143 ** others have been introduced:
4144 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4145 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4147 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4149 * support/scripts/inc2h.pl: changed definition of BIT_AT
4150 to emit 'sbit at' instead of 'bit at'. This was a request.
4152 PIC16 port related preliminary changes:
4153 * gen.c: prefixed function popRegFromString with
4154 pic16_ and all references to it corrected
4155 * pcode.c: all pic16_pc_* hardware registers prefixed
4156 with underscore (_),
4157 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4158 * ralloc.c: newReg(): when register is REG_SFR then
4159 set address to rIdx,
4160 pic16_allocProcessorRegister(): marks register wasUsed=0
4161 pic16_writeUsedRegs(): added a call to assign processor
4162 registers via pic16_assignFixedRegisters
4164 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4166 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4167 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4168 variables in unused register banks. Also the SSEG is placed
4169 wherever there is enough space for it, and IDATA can be anywhere
4170 in internal RAM. For now compile using -Wl-Y[stack_size].
4171 The mem file is different for this option as well, since it
4172 makes no sense of talking about DSEG lenght.
4174 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4176 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4177 in certain cases, e.g. when ROM assignment, patch provided
4178 from Albert den Haan.

4323 * src/mcs51/peephole.def,
4324 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

4419 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4421 * src/SDCCast.c (decorateType): disabled a transformation I added in
4422 revision 1.188 (access to fields of a structure at an absolute address);
4423 it breaks with bitfields, extern declarations, and gcse analysis.
4424 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4425 could be assigned through a pointer, so don't complain.
4426 * src/SDCCast.c (astErrors),
4428 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5066 support for standard C idiom of memory mapped variables; for
5067 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5068 to xdata int at 0x1234 tempvar = 1.
5069 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

5086 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5088 Fixed bug #621531 (const & volatile confusion in the type chain).
5089 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
5090 refer to the const or volatile state of the pointer itself.

5181 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5182 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5183 fetching of the pointer
5184 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5185 copied from genNearPointerSet()
5186 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5187 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5188 If they pop r0/r1 they must be called in the opposite order than aopOp().

5201 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5203 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5204 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5205 type for bits was changed. It resulted in bit variables becoming
5206 global, which is not permitted in PIC 14 assembly output.
5208 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5210 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5223 A few small changes that speed up the peephole optimizer.
5227 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5229 Try to make the peephole optimizer smarter by maintaining
5230 an association between the assembly source code and the
5231 iCodes that originated them. Put this information to use
5232 with a new peephole rule condition "notVolatile" so that
5233 the rules can be aggressive yet still safe.
5238 * src/mcs51/peeph.def
5240 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5244 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5245 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5246 if the left or right operand symbols have the accuse flag set.
5248 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5250 Changed the type of the result of the ! (NOT) operator to char;
5251 previously it returned the same type as the source. This allows
5252 us to eliminate all the genFloatNot functions (all of its target
5253 implementations were very buggy) since !float can use the same

5265 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5266 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5267 during interrupts. Ensure WSAVE is located at a shared bank address.
5268 2. Fixed page selection in some places
5269 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5270 the registers name strings.
5271 4. Fixed "signed / unsigned compare" compiler warnings.
5272 5. The PIC port manages its own allocation of the general purpose
5273 registers, but makes no attempt to reuse them. As a result when
5274 compiling it soon runs out of general purpose registers. Some
5275 additional code was added to the files pcode.c and device.c to walk
5276 through the function call tree and rename the registers so that they
5286 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5287 genPlus() & genMinus() when the result is the same as left or right

5293 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5295 Made bitfield a distinct type from bit so that bitfields
5296 convert as per ANSI C and bits retain their traditional
5297 boolean style behaviour. Implemented bitfield support in
5305 * src/ds390/gen.c: bit v bitfield split
5306 * src/z80/gen.c: New support for bitfields
5307 * support/regression/tests/bitfields.c: reenabled z80,
5310 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5312 Rules 246.x, 247.x relate to bitfields, the others speed up
5313 access to xdata mapped I/O devices.
5315 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5317 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5319 Cleaned up genPackBits and genUnpackBits and added two helper
5320 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5321 for literal assignments in genPackBits (thanks to Frieder for
5327 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5329 Fixed bug #748310 (pointer to function type mishandled when the
5330 function name is omitted). Also fixed a SIGSEGV when a function
5331 attribute (reentrant, etc) is used on a non-function or on a
5332 function but misplaced before the parameter list.
5334 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5336 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5337 * support/Util/SDCCerr.h,
5338 * support/Util/SDCCerr.c: Added func attr misuse error msg

5359 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5361 Made the constant following the "interrupt" keyword optional. If
5362 omitted, the function will not automatically be given an entry
5363 in the interrupt vector table (similar to #pragma NOIV, but
5364 less syntacticly kludgy). The interrupt number is also now
5365 range checked. Also fixed a bug in the high order bit example

5379 * src/SDCCicode.c (operandOperation): rewritten some ops
5380 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5381 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5383 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5384 be re-activated by defining REDUCE_LITERALS)
5385 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5386 unsigned, but are signed by default
5387 * src/SDCCval.c (constVal): rearranged
5388 * src/SDCCval.c (valMod): preliminary fix
5389 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5431 constants are unsigned; added recognition of "u" flag for unsigned
5432 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5433 * src/SDCCval.c (valDiv, valMod): fixed signdness
5434 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5435 signedness of modulo, left and right shift

5894 * src/SDCCmain.c: linkOptions is changed to set *,
5895 added if/endif conditional macros to remove options help
5896 messages from optionsTable when a port is not configured, added
5897 support for the PIc16 port in the ports table, when executing
5898 the compiler with no port specified on command line, a default
5899 port is selected with the new macro DEFAULT_PORT which is
5900 defined in port.h, in setDefaultOptions() linkOptions is removed
5901 from initialization assignment, since now it is a set,
5902 parseCmdLine uses setParseWithComma for linkOptions, in
5903 linkEdit() linkOptions are accessed with new function indexSet()
5904 which returns the i'th item of a set variable. See SDCCset.c, in
5905 linkEdit() when calling buildCmdLine(), added linkOptions as
5906 last argument. Now users can pass arguments to gplink via the
5907 -Wl option, main() uses pic16glue() to glue up pic16 programs

5921 gpasm complaining and test the linkage with gplink, _linkCmd and
5922 _asmCmd changed to be more gplink and gpasm friendly
5923 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5924 produced an error when parsed, peep rule 12 is added to utilize
5925 movff, but it is commented out since the pCode does not support
5926 yet a command with 2 address arguments
5928 2003-05-18 <johan AT balder>
5930 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5957 2003-05-11 Borut Razem <borut.razem AT siol.net>
5959 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5960 the path of bin directory, so that PATH is the only env. variable, which has to be set

6986 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6988 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6989 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6991 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6993 * in \sdcc\as\mcs51\ changed these files in order to create an
6994 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6995 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6996 following files to include the previous two files: aslink.dsp,
6997 Makefile.aslink, Makefile.bcc, and Makefile.in.
6999 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7000 .adb instead of .cdb
7002 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7004 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7005 value from option --iram-size.
7007 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7009 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7012 2002-09-18 <wiml AT hhhh.org>
7014 * SDCClrange.h: exposed setFromRange() and setToRange()
7015 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7016 packRegsForAccUse() (bug 542397)
7017 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7018 multiple times and emitting the fetch operations more than once
7019 added aopGetUsesAcc() function to allow binary operators to
7020 fetch their operands in the correct order; made genMinus() emit
7021 compact code for X = LITERAL - Y
7023 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7024 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7025 sprintf() in line 1267.
7027 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7028 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7031 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7032 Changes to aslink (All the changes are marked with 'JCF'):
7034 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7037 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7038 area BSEG. Also moves, if possible, the DATA area down into the internal
7039 ram so more space is available.
7041 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7044 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7045 not bytes. Function summary() which creates a memory usage summary
7046 file with extension .mem. Reports of overlaping stack and small stack
7047 size. If the space for the stack is less than 16 bytes aslink trows a
7050 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7051 the 8051. Option 'y' for memory summary output file.
7053 Changes to sdcc (All the changes are marked with 'JCF'):
7055 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7057 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7058 overlaying area for it (uses RegBankUsed[4]).
7060 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7061 bank zero as used by default. By default aslink locates the stack
7062 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7063 the creation of the .mem file. Delegates the allocation of data area
7064 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7065 the begining of the stack area to aslink.
7067 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7068 glue() in SDCCglue.c creates an area for it.
7070 2002-09-03 Borut Razem <borut.razem AT siol.net>
7071 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7072 sdcc/src/pic/glue.c:
7073 introduced atexit() handler for teporay files removal in case of
7074 errors, assertions, ...
7076 2002-08-29 Borut Razem <borut.razem AT siol.net>
7077 * sdcc/support/cpp2/auto-host_vc_in.h:
7078 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7079 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7080 Maybe there is a similar problem with BORLANDC? It should be checked!
7082 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7083 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7084 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7085 was not executed, and the compiler (cl) launched a warning:
7086 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7088 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7089 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7091 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7092 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7094 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7095 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7096 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7097 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7098 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7099 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7100 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7101 - added Release configuration in VS projects
7102 - review of compiler an linker options
7103 - VC .exe files are generated in bin_vc directory, not to interfere
7104 with binaries generated from other projects (cygwin, mingw, bcc ...)
7106 * sdcc/src/yacc.dsp: added
7108 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7109 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7110 and insert the version number definitions from .version
7112 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7114 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7115 added - genarate auto-host.h using auto-host_vc_in.h as template
7118 removed from CVS, generated automatically
7120 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7121 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7123 2002-08-11 Borut Razem <borut.razem AT siol.net>
7124 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7126 2002-08-10 Borut Razem <borut.razem AT siol.net>
7127 * src/SDCCmain.c (main):
7128 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7129 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7130 The consequence was that some temporary files were not removed.
7133 unification of code in functions tempfilename() and tempfile():
7134 function tempnam() is defined in Visual Studio 6.0 and .NET
7136 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7138 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7139 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7140 - removed compiler command line option /WX: Treats all warnings as errors
7141 - update a list of source files, included into the project
7143 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7144 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7145 changed project type to Generic Project so that can be correcly converted to VS.NET project
7147 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7149 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7151 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7153 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7154 added return 0 statements after assert() to make compiler happy
7156 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7157 added newline in the def file to keep MSC compiler satisfied
7159 * sdcc/src/z80/gen.c:
7160 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7161 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7162 - solved MSC error in function aopDump()
7164 * sdcc_vc.h: define PREFIX as "\\sdcc"
7166 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7167 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7169 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7170 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7171 - Rewrote the register banking algorithm.
7172 - Added pCode live-range analysis to registers (for now, only non-used and
7173 singly-used registers optimized away)
7175 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7177 * 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.
7179 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7180 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

7204 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7206 2002-03-28 Johan Knol <johan AT balder>
7208 * src/SDCCval.c: fixed bug #532436
7210 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7212 Added "char *Processor" field to the port structure.
7215 Added -p option. Allows port dependent processor to be specified.
7218 Initialized the new field char *Processor field to NULL in all ports
7221 Compiler generated registers for interrupt context saving
7222 were not getting allocated.
7224 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7227 Fixed left shift. Will promote the left side of a left shift
7228 if a) left shifting more than size of operand or b) when assigned
7229 to something size > size of left side
7231 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7233 tons of changes. Register allocation has been
7234 rewritten. Added customization for the various PICs. Flow
7235 analysis is restructured. ...
7241 Added. device.c is a PIC port hack to accomodate variations
7244 2002-03-13 Michael Hope <michaelh AT vroom>
7246 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7339 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7341 * sdcc/src/SDCCloop.c:
7342 Previous fix was not good. basic blocks that have "break" or "return" are
7343 not really partof a loop , but live ranges used in these blocks should
7344 be live thru the entire loop, so set partOfLoop but don't add them to
7347 2002-02-21 <johan AT FRIJA>
7349 * src/SDCCcse.c: fixed bug #514308
7351 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7354 Fixed BUG #519583. If a conditional block ended in a return/break
7355 statement inside a loop, it was not being considered part of the loop.
7357 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7359 2002-02-10 Karl Bongers <karl AT turbobit.com>
7362 Fixed up SDCDB debugger somewhat. Updated debugger/README
7363 with lots of comments and notes.
7365 * device/examples/test2.c:
7366 Fix bug, "red" variable not being initialized(compiler complained).
7368 * device/examples/Makefile, examples/test3.c:
7369 Add Makefile in device/examples folder, compiles test3.c
7370 for use as a multiple module SDCDB test case.
7372 * sim/ucsim/cmd.src/cmdset.cc:
7373 Took out debug printfs in ucsim "next" command.
7376 Karl and Johan start ucsim XA support. Most dissassembly working,
7377 about 75% emulation done(plenty of work remaining).
7379 * sim/ucsim/z80.src:
7380 Add Z80 support to ucsim, add test-ucz80 regression test,
7381 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

7417 set preprocessor defines (depending on options)
7419 * src/SDCCicode.c, src/SDCCicode.h:
7420 changes made to handle multiple sends & receives
7423 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
