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

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

699 * (pic16_storeForReturn): optimized return of 0,
700 * (genCmp): experimental code for new genCmp which uses PIC18's
701 special compare&skip instructions. Initial tests fail some times
702 with variables grater than 1 byte in size, so new code is disabled,
703 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
705 * (genCast): began a fix to optimize the casting of a bit to another
706 bit, now assigning a bitfield to another bitfield will fail, sorry,

3729 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3731 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3732 loaded with the linker search paths (-L arguments) and the libraries
3733 to be linked with the current source (-l arguments). Changes
3734 currently will affect only the pic16 port.
3735 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3736 include path the port specific paths and port specific libraries,
3737 * gplink command now contains the $3 argument,
3738 * src/pic16/device.h,
3739 * src/pic16/device.c,: structure PIC_device is made public and

3755 Documenting changes from previous commits.
3756 * configure.in (version 1.56),
3757 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3758 when generating output files to configure the pic16 library,
3759 but now I've commented it out, since gputils aren't installed in the
3760 SF compile farm, so library won't compile
3762 * device/lib/Makefile.in (version 1.56): initially I've added in
3763 target 'all' the prerequestive 'model-pic16' so it compiled the
3764 pic16 library, but now I've commented it out for the same reasons
3766 * added targets 'model-pic16' and 'objects-pic16' to compile the
3768 * added target 'port-specific-objects-pic16' to handle the
3769 generated libraries and copy them into the build/ directory
3770 * added target 'clean-intermediate-pic16' to clean intermediate
3771 files into pic16 directory
3772 * in target 'installdirs' added line to create directory pic16 in

3776 added lines to copy all header files to installation path,
3777 * in target 'installdirs' added line create directory for pic16
3778 headers in the installation path

4065 PIC16 port related changes:
4066 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4067 added variable stackPos,
4069 * gen.c: genCall, assignResultValue: added support for
4070 pushing/retrieving function parameters to/from stack,
4071 genFunction,genEndFunction: setup stack frame for the
4073 genAddrOf: will be changed according to bug 863624
4075 * added files genutils.c and genutils.h which contain gen*
4076 debugged and optimised functions extracted from gen.c
4078 * glue.c: added variable 'externs' which holds extern symbols,
4079 pic16emitRegularMap: is modified to properly handle relocatable
4080 symbols under the new scheme,
4081 pic16createInterruptVect: is modified
4082 pic16printPublics: is modified to emit 'global' assembler directives,
4083 added pic16_printExterns to print extern symbols,
4084 pic16glue: initializes stack/frame pointer in the beginning of
4085 the assembly output. Temporary hack, will be corrected later,
4086 because gplink yet does not support stack and SDCC does not
4087 yet support a type of crt0.o object to create the final binary.
4089 * Removed many lines that contain 8051 legacy code.
4090 * The code is finally placed under a 'code' directive.
4091 * Added port specific options.
4093 * _process_pragma: simplified since now we do not need *special*
4094 include file to define SFR registers. But a separate header
4095 will be needed. This will be developed later.
4096 * _pic16_parseOptions: added, parses port specific options:
4097 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4098 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4099 --preplace-udata-with=
4101 * _pic16_setDefaultOptions: modified to initialize section names,
4102 but hack is temporarly out of order since it needs improvement.
4103 * _pic16_genAssemblerPreamble: configuration words are emitted by
4104 their address instead of their name. This part is incomplete and
4105 supports only the 18Fxx2 devices. Other devices will emit an error
4106 during assembly since they do not contain the same set of config
4108 * _pic16_genIVT: is modified,
4110 * pcode.c: added definitions for some hardware registers that are needed
4112 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4113 All PCI entries are updated. Now LFSR is supported.
4114 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4115 * added pic16_newpCodeOpLit2 to support instructions with
4116 two literal arguments
4117 * pic16_pCode2str: corrected code that emits assembler instructions
4118 with two literal operands and those that have an access bit modifier
4119 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4120 this fixes a bug which caused some labels to be lost, when an
4121 assembler directive was added, i.e. banksel,
4122 * pic16_FixRegisterBanking: improved logic that causes the insertion
4124 * InlineFunction: functions that are called once, are not any more
4125 inlined. This can be a port option in the future,
4127 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4129 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4130 hold the corresponding uninitialized symbols,
4131 * pic16_allocProcessorRegister: registers have explicit marked the
4133 * pic16_allocInternalRegister: registers are explicit marked as
4135 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4136 processing list, so bit registers were lost,
4139 * ralloc.h: added field 'accessBank' and original symbol operand
4140 in register definition,
4141 * removed the field isMapped from register definition,
4143 ** Several functions have been removed from various sources:
4144 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4145 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4146 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4147 pic16_assignRelocatableRegisters
4149 ** others have been introduced:
4150 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4151 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4153 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4155 * support/scripts/inc2h.pl: changed definition of BIT_AT
4156 to emit 'sbit at' instead of 'bit at'. This was a request.
4158 PIC16 port related preliminary changes:
4159 * gen.c: prefixed function popRegFromString with
4160 pic16_ and all references to it corrected
4161 * pcode.c: all pic16_pc_* hardware registers prefixed
4162 with underscore (_),
4163 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4164 * ralloc.c: newReg(): when register is REG_SFR then
4165 set address to rIdx,
4166 pic16_allocProcessorRegister(): marks register wasUsed=0
4167 pic16_writeUsedRegs(): added a call to assign processor
4168 registers via pic16_assignFixedRegisters
4170 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4172 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4173 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4174 variables in unused register banks. Also the SSEG is placed
4175 wherever there is enough space for it, and IDATA can be anywhere
4176 in internal RAM. For now compile using -Wl-Y[stack_size].
4177 The mem file is different for this option as well, since it
4178 makes no sense of talking about DSEG lenght.
4180 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4182 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4183 in certain cases, e.g. when ROM assignment, patch provided
4184 from Albert den Haan.
4186 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4427 * src/SDCCast.c (decorateType): disabled a transformation I added in
4428 revision 1.188 (access to fields of a structure at an absolute address);
4429 it breaks with bitfields, extern declarations, and gcse analysis.
4430 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4431 could be assigned through a pointer, so don't complain.
4432 * src/SDCCast.c (astErrors),

5072 support for standard C idiom of memory mapped variables; for
5073 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5074 to xdata int at 0x1234 tempvar = 1.
5075 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5076 provided by Akiya ISHIDA

5092 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5094 Fixed bug #621531 (const & volatile confusion in the type chain).
5095 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5188 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5189 fetching of the pointer
5190 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5191 copied from genNearPointerSet()
5192 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5193 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5209 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5210 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5211 type for bits was changed. It resulted in bit variables becoming
5212 global, which is not permitted in PIC 14 assembly output.
5214 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5216 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5229 A few small changes that speed up the peephole optimizer.
5233 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5235 Try to make the peephole optimizer smarter by maintaining
5236 an association between the assembly source code and the
5237 iCodes that originated them. Put this information to use
5238 with a new peephole rule condition "notVolatile" so that
5239 the rules can be aggressive yet still safe.
5244 * src/mcs51/peeph.def
5246 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5250 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5251 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5252 if the left or right operand symbols have the accuse flag set.
5254 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5256 Changed the type of the result of the ! (NOT) operator to char;
5257 previously it returned the same type as the source. This allows
5258 us to eliminate all the genFloatNot functions (all of its target
5259 implementations were very buggy) since !float can use the same
5262 * src/SDCCicode.c (ast2iCode): ! returns char

5271 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5272 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5273 during interrupts. Ensure WSAVE is located at a shared bank address.
5274 2. Fixed page selection in some places
5275 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5276 the registers name strings.
5277 4. Fixed "signed / unsigned compare" compiler warnings.
5278 5. The PIC port manages its own allocation of the general purpose
5279 registers, but makes no attempt to reuse them. As a result when
5280 compiling it soon runs out of general purpose registers. Some
5281 additional code was added to the files pcode.c and device.c to walk
5282 through the function call tree and rename the registers so that they
5292 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5293 genPlus() & genMinus() when the result is the same as left or right

5299 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5301 Made bitfield a distinct type from bit so that bitfields
5302 convert as per ANSI C and bits retain their traditional
5303 boolean style behaviour. Implemented bitfield support in
5311 * src/ds390/gen.c: bit v bitfield split
5312 * src/z80/gen.c: New support for bitfields
5313 * support/regression/tests/bitfields.c: reenabled z80,
5316 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5318 Rules 246.x, 247.x relate to bitfields, the others speed up
5319 access to xdata mapped I/O devices.
5321 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5323 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5325 Cleaned up genPackBits and genUnpackBits and added two helper
5326 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5327 for literal assignments in genPackBits (thanks to Frieder for
5333 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5335 Fixed bug #748310 (pointer to function type mishandled when the
5336 function name is omitted). Also fixed a SIGSEGV when a function
5337 attribute (reentrant, etc) is used on a non-function or on a
5338 function but misplaced before the parameter list.
5340 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5342 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5343 * support/Util/SDCCerr.h,
5344 * support/Util/SDCCerr.c: Added func attr misuse error msg
5346 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5348 Fixed bug #787649 by anonymous
5349 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

5365 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5367 Made the constant following the "interrupt" keyword optional. If
5368 omitted, the function will not automatically be given an entry
5369 in the interrupt vector table (similar to #pragma NOIV, but
5370 less syntacticly kludgy). The interrupt number is also now
5371 range checked. Also fixed a bug in the high order bit example

5385 * src/SDCCicode.c (operandOperation): rewritten some ops
5386 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5387 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5389 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5390 be re-activated by defining REDUCE_LITERALS)
5391 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5392 unsigned, but are signed by default
5393 * src/SDCCval.c (constVal): rearranged
5394 * src/SDCCval.c (valMod): preliminary fix
5395 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5437 constants are unsigned; added recognition of "u" flag for unsigned
5438 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5439 * src/SDCCval.c (valDiv, valMod): fixed signdness
5440 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5441 signedness of modulo, left and right shift

5901 added if/endif conditional macros to remove options help
5902 messages from optionsTable when a port is not configured, added
5903 support for the PIc16 port in the ports table, when executing
5904 the compiler with no port specified on command line, a default
5905 port is selected with the new macro DEFAULT_PORT which is
5906 defined in port.h, in setDefaultOptions() linkOptions is removed
5907 from initialization assignment, since now it is a set,
5908 parseCmdLine uses setParseWithComma for linkOptions, in
5909 linkEdit() linkOptions are accessed with new function indexSet()
5910 which returns the i'th item of a set variable. See SDCCset.c, in
5911 linkEdit() when calling buildCmdLine(), added linkOptions as
5912 last argument. Now users can pass arguments to gplink via the
5913 -Wl option, main() uses pic16glue() to glue up pic16 programs

5927 gpasm complaining and test the linkage with gplink, _linkCmd and
5928 _asmCmd changed to be more gplink and gpasm friendly
5929 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5930 produced an error when parsed, peep rule 12 is added to utilize
5931 movff, but it is commented out since the pCode does not support
5932 yet a command with 2 address arguments
5934 2003-05-18 <johan AT balder>
5936 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5963 2003-05-11 Borut Razem <borut.razem AT siol.net>
5965 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5966 the path of bin directory, so that PATH is the only env. variable, which has to be set

6988 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6989 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6991 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6992 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6994 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6995 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6997 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6999 * in \sdcc\as\mcs51\ changed these files in order to create an
7000 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7001 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7002 following files to include the previous two files: aslink.dsp,
7003 Makefile.aslink, Makefile.bcc, and Makefile.in.
7005 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7006 .adb instead of .cdb
7008 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7010 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7011 value from option --iram-size.
7013 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7015 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7018 2002-09-18 <wiml AT hhhh.org>
7020 * SDCClrange.h: exposed setFromRange() and setToRange()
7021 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7022 packRegsForAccUse() (bug 542397)
7023 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7024 multiple times and emitting the fetch operations more than once
7025 added aopGetUsesAcc() function to allow binary operators to
7026 fetch their operands in the correct order; made genMinus() emit
7027 compact code for X = LITERAL - Y
7029 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7030 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7031 sprintf() in line 1267.
7033 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7034 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7037 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7038 Changes to aslink (All the changes are marked with 'JCF'):
7040 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7043 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7044 area BSEG. Also moves, if possible, the DATA area down into the internal
7045 ram so more space is available.
7047 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7050 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7051 not bytes. Function summary() which creates a memory usage summary
7052 file with extension .mem. Reports of overlaping stack and small stack
7053 size. If the space for the stack is less than 16 bytes aslink trows a
7056 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7057 the 8051. Option 'y' for memory summary output file.
7059 Changes to sdcc (All the changes are marked with 'JCF'):
7061 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7063 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7064 overlaying area for it (uses RegBankUsed[4]).
7066 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7067 bank zero as used by default. By default aslink locates the stack
7068 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7069 the creation of the .mem file. Delegates the allocation of data area
7070 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7071 the begining of the stack area to aslink.
7073 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7074 glue() in SDCCglue.c creates an area for it.
7076 2002-09-03 Borut Razem <borut.razem AT siol.net>
7077 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7078 sdcc/src/pic/glue.c:
7079 introduced atexit() handler for teporay files removal in case of
7080 errors, assertions, ...
7082 2002-08-29 Borut Razem <borut.razem AT siol.net>
7083 * sdcc/support/cpp2/auto-host_vc_in.h:
7084 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7085 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7086 Maybe there is a similar problem with BORLANDC? It should be checked!
7088 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7089 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7090 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7091 was not executed, and the compiler (cl) launched a warning:
7092 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7094 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7095 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7097 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7098 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7100 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7101 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7102 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7103 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7104 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7105 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7106 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7107 - added Release configuration in VS projects
7108 - review of compiler an linker options
7109 - VC .exe files are generated in bin_vc directory, not to interfere
7110 with binaries generated from other projects (cygwin, mingw, bcc ...)
7112 * sdcc/src/yacc.dsp: added
7114 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7115 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7116 and insert the version number definitions from .version
7118 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7120 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7121 added - genarate auto-host.h using auto-host_vc_in.h as template
7124 removed from CVS, generated automatically
7126 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7127 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7129 2002-08-11 Borut Razem <borut.razem AT siol.net>
7130 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7132 2002-08-10 Borut Razem <borut.razem AT siol.net>
7133 * src/SDCCmain.c (main):
7134 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7135 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7136 The consequence was that some temporary files were not removed.
7139 unification of code in functions tempfilename() and tempfile():
7140 function tempnam() is defined in Visual Studio 6.0 and .NET
7142 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7144 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7145 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7146 - removed compiler command line option /WX: Treats all warnings as errors
7147 - update a list of source files, included into the project
7149 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7150 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7151 changed project type to Generic Project so that can be correcly converted to VS.NET project
7153 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7155 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7157 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7159 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7160 added return 0 statements after assert() to make compiler happy
7162 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7163 added newline in the def file to keep MSC compiler satisfied
7165 * sdcc/src/z80/gen.c:
7166 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7167 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7168 - solved MSC error in function aopDump()
7170 * sdcc_vc.h: define PREFIX as "\\sdcc"
7172 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7173 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7176 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7177 - Rewrote the register banking algorithm.
7178 - Added pCode live-range analysis to registers (for now, only non-used and
7179 singly-used registers optimized away)
7181 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7183 * 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.

7212 2002-03-28 Johan Knol <johan AT balder>
7214 * src/SDCCval.c: fixed bug #532436
7216 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7218 Added "char *Processor" field to the port structure.
7221 Added -p option. Allows port dependent processor to be specified.
7224 Initialized the new field char *Processor field to NULL in all ports
7227 Compiler generated registers for interrupt context saving
7228 were not getting allocated.
7230 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7233 Fixed left shift. Will promote the left side of a left shift
7234 if a) left shifting more than size of operand or b) when assigned
7235 to something size > size of left side
7237 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7239 tons of changes. Register allocation has been
7240 rewritten. Added customization for the various PICs. Flow
7241 analysis is restructured. ...
7247 Added. device.c is a PIC port hack to accomodate variations
7250 2002-03-13 Michael Hope <michaelh AT vroom>
7252 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7345 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7347 * sdcc/src/SDCCloop.c:
7348 Previous fix was not good. basic blocks that have "break" or "return" are
7349 not really partof a loop , but live ranges used in these blocks should
7350 be live thru the entire loop, so set partOfLoop but don't add them to
7353 2002-02-21 <johan AT FRIJA>
7355 * src/SDCCcse.c: fixed bug #514308
7357 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7360 Fixed BUG #519583. If a conditional block ended in a return/break
7361 statement inside a loop, it was not being considered part of the loop.
7363 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7365 2002-02-10 Karl Bongers <karl AT turbobit.com>
7368 Fixed up SDCDB debugger somewhat. Updated debugger/README
7369 with lots of comments and notes.
7371 * device/examples/test2.c:
7372 Fix bug, "red" variable not being initialized(compiler complained).
7374 * device/examples/Makefile, examples/test3.c:
7375 Add Makefile in device/examples folder, compiles test3.c
7376 for use as a multiple module SDCDB test case.
7378 * sim/ucsim/cmd.src/cmdset.cc:
7379 Took out debug printfs in ucsim "next" command.
7382 Karl and Johan start ucsim XA support. Most dissassembly working,
7383 about 75% emulation done(plenty of work remaining).
7385 * sim/ucsim/z80.src:
7386 Add Z80 support to ucsim, add test-ucz80 regression test,
7387 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

7423 set preprocessor defines (depending on options)
7425 * src/SDCCicode.c, src/SDCCicode.h:
7426 changes made to handle multiple sends & receives
7429 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
