2903 loaded with the linker search paths (-L arguments) and the libraries
2904 to be linked with the current source (-l arguments). Changes
2905 currently will affect only the pic16 port.
2906 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2907 include path the port specific paths and port specific libraries,
2908 * gplink command now contains the $3 argument,
2909 * src/pic16/device.h,

2926 Documenting changes from previous commits.
2927 * configure.in (version 1.56),
2928 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2929 when generating output files to configure the pic16 library,
2930 but now I've commented it out, since gputils aren't installed in the
2931 SF compile farm, so library won't compile
2933 * device/lib/Makefile.in (version 1.56): initially I've added in
2934 target 'all' the prerequestive 'model-pic16' so it compiled the
2935 pic16 library, but now I've commented it out for the same reasons
2937 * added targets 'model-pic16' and 'objects-pic16' to compile the
2939 * added target 'port-specific-objects-pic16' to handle the
2940 generated libraries and copy them into the build/ directory
2941 * added target 'clean-intermediate-pic16' to clean intermediate
2942 files into pic16 directory
2943 * in target 'installdirs' added line to create directory pic16 in

3208 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3209 * src/SDCCsymt.c (newEnumType),
3211 * support/Util/SDCCerr.c,
3212 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3214 * support/regression/tests/enum.c: added test for enum values that
3215 require at least 2 bytes of storage.
3217 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3219 * src/common.h: added ifndef/define/endif macros
3220 around the header file.
3221 Bug reported from Jesus Calvino-Fraga
3223 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3225 * sdcc.spec: updated
3226 * device/include/Makefile.in: don't install CVS directories
3227 * device/lib/Makefile.in: added removal of CVS directories after install
3228 * doc/Makefile: fixed install, added local_icons
3229 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3230 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3231 * src/ds390/gen.c (genRightShift): fixed bug #870788
3232 * src/SDCCast.c (decorateType): fixed bug #870781
3234 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3236 PIC16 port related changes:
3237 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3238 added variable stackPos,
3240 * gen.c: genCall, assignResultValue: added support for
3241 pushing/retrieving function parameters to/from stack,
3242 genFunction,genEndFunction: setup stack frame for the
3244 genAddrOf: will be changed according to bug 863624
3246 * added files genutils.c and genutils.h which contain gen*
3247 debugged and optimised functions extracted from gen.c
3249 * glue.c: added variable 'externs' which holds extern symbols,
3250 pic16emitRegularMap: is modified to properly handle relocatable
3251 symbols under the new scheme,
3252 pic16createInterruptVect: is modified
3253 pic16printPublics: is modified to emit 'global' assembler directives,
3254 added pic16_printExterns to print extern symbols,
3255 pic16glue: initializes stack/frame pointer in the beginning of
3256 the assembly output. Temporary hack, will be corrected later,
3257 because gplink yet does not support stack and SDCC does not
3258 yet support a type of crt0.o object to create the final binary.
3260 * Removed many lines that contain 8051 legacy code.
3261 * The code is finally placed under a 'code' directive.
3262 * Added port specific options.
3264 * _process_pragma: simplified since now we do not need *special*
3265 include file to define SFR registers. But a separate header
3266 will be needed. This will be developed later.
3267 * _pic16_parseOptions: added, parses port specific options:
3268 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3269 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3270 --preplace-udata-with=
3272 * _pic16_setDefaultOptions: modified to initialize section names,
3273 but hack is temporarly out of order since it needs improvement.
3274 * _pic16_genAssemblerPreamble: configuration words are emitted by
3275 their address instead of their name. This part is incomplete and
3276 supports only the 18Fxx2 devices. Other devices will emit an error
3277 during assembly since they do not contain the same set of config
3279 * _pic16_genIVT: is modified,
3281 * pcode.c: added definitions for some hardware registers that are needed
3283 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3284 All PCI entries are updated. Now LFSR is supported.
3285 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3286 * added pic16_newpCodeOpLit2 to support instructions with
3287 two literal arguments
3288 * pic16_pCode2str: corrected code that emits assembler instructions
3289 with two literal operands and those that have an access bit modifier
3290 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3291 this fixes a bug which caused some labels to be lost, when an
3292 assembler directive was added, i.e. banksel,
3293 * pic16_FixRegisterBanking: improved logic that causes the insertion
3295 * InlineFunction: functions that are called once, are not any more
3296 inlined. This can be a port option in the future,
3298 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3300 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3301 hold the corresponding uninitialized symbols,
3302 * pic16_allocProcessorRegister: registers have explicit marked the
3304 * pic16_allocInternalRegister: registers are explicit marked as
3306 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3307 processing list, so bit registers were lost,
3310 * ralloc.h: added field 'accessBank' and original symbol operand
3311 in register definition,
3312 * removed the field isMapped from register definition,
3314 ** Several functions have been removed from various sources:
3315 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3316 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3317 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3318 pic16_assignRelocatableRegisters
3320 ** others have been introduced:
3321 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3322 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3324 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3326 * support/scripts/inc2h.pl: changed definition of BIT_AT
3327 to emit 'sbit at' instead of 'bit at'. This was a request.
3329 PIC16 port related preliminary changes:
3330 * gen.c: prefixed function popRegFromString with
3331 pic16_ and all references to it corrected
3332 * pcode.c: all pic16_pc_* hardware registers prefixed
3333 with underscore (_),
3334 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3335 * ralloc.c: newReg(): when register is REG_SFR then
3336 set address to rIdx,
3337 pic16_allocProcessorRegister(): marks register wasUsed=0
3338 pic16_writeUsedRegs(): added a call to assign processor
3339 registers via pic16_assignFixedRegisters
3341 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3343 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3344 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3345 variables in unused register banks. Also the SSEG is placed
3346 wherever there is enough space for it, and IDATA can be anywhere
3347 in internal RAM. For now compile using -Wl-Y[stack_size].
3348 The mem file is different for this option as well, since it
3349 makes no sense of talking about DSEG lenght.
3351 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3353 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3354 in certain cases, e.g. when ROM assignment, patch provided
3355 from Albert den Haan.

3598 * src/SDCCast.c (decorateType): disabled a transformation I added in
3599 revision 1.188 (access to fields of a structure at an absolute address);
3600 it breaks with bitfields, extern declarations, and gcse analysis.
3601 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3602 could be assigned through a pointer, so don't complain.
3603 * src/SDCCast.c (astErrors),
3605 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4244 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4245 to xdata int at 0x1234 tempvar = 1.
4246 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4247 provided by Akiya ISHIDA

4263 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4265 Fixed bug #621531 (const & volatile confusion in the type chain).
4266 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4359 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4360 fetching of the pointer
4361 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4362 copied from genNearPointerSet()
4363 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4364 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

4378 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4380 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4381 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4382 type for bits was changed. It resulted in bit variables becoming
4383 global, which is not permitted in PIC 14 assembly output.
4385 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4387 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4400 A few small changes that speed up the peephole optimizer.
4404 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4406 Try to make the peephole optimizer smarter by maintaining
4407 an association between the assembly source code and the
4408 iCodes that originated them. Put this information to use
4409 with a new peephole rule condition "notVolatile" so that
4410 the rules can be aggressive yet still safe.
4415 * src/mcs51/peeph.def
4417 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4421 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4422 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4423 if the left or right operand symbols have the accuse flag set.
4425 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4427 Changed the type of the result of the ! (NOT) operator to char;
4428 previously it returned the same type as the source. This allows
4429 us to eliminate all the genFloatNot functions (all of its target
4430 implementations were very buggy) since !float can use the same
4433 * src/SDCCicode.c (ast2iCode): ! returns char

4442 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4443 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4444 during interrupts. Ensure WSAVE is located at a shared bank address.
4445 2. Fixed page selection in some places
4446 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4447 the registers name strings.
4448 4. Fixed "signed / unsigned compare" compiler warnings.
4449 5. The PIC port manages its own allocation of the general purpose
4450 registers, but makes no attempt to reuse them. As a result when
4451 compiling it soon runs out of general purpose registers. Some
4452 additional code was added to the files pcode.c and device.c to walk
4453 through the function call tree and rename the registers so that they
4463 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4464 genPlus() & genMinus() when the result is the same as left or right

4470 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4472 Made bitfield a distinct type from bit so that bitfields
4473 convert as per ANSI C and bits retain their traditional
4474 boolean style behaviour. Implemented bitfield support in
4482 * src/ds390/gen.c: bit v bitfield split
4483 * src/z80/gen.c: New support for bitfields
4484 * support/regression/tests/bitfields.c: reenabled z80,
4487 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4489 Rules 246.x, 247.x relate to bitfields, the others speed up
4490 access to xdata mapped I/O devices.
4492 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4494 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4496 Cleaned up genPackBits and genUnpackBits and added two helper
4497 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4498 for literal assignments in genPackBits (thanks to Frieder for
4504 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4506 Fixed bug #748310 (pointer to function type mishandled when the
4507 function name is omitted). Also fixed a SIGSEGV when a function
4508 attribute (reentrant, etc) is used on a non-function or on a
4509 function but misplaced before the parameter list.
4511 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4513 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4514 * support/Util/SDCCerr.h,
4515 * support/Util/SDCCerr.c: Added func attr misuse error msg

4536 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4538 Made the constant following the "interrupt" keyword optional. If
4539 omitted, the function will not automatically be given an entry
4540 in the interrupt vector table (similar to #pragma NOIV, but
4541 less syntacticly kludgy). The interrupt number is also now
4542 range checked. Also fixed a bug in the high order bit example

4556 * src/SDCCicode.c (operandOperation): rewritten some ops
4557 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4558 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4560 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4561 be re-activated by defining REDUCE_LITERALS)
4562 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4563 unsigned, but are signed by default
4564 * src/SDCCval.c (constVal): rearranged
4565 * src/SDCCval.c (valMod): preliminary fix
4566 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5072 added if/endif conditional macros to remove options help
5073 messages from optionsTable when a port is not configured, added
5074 support for the PIc16 port in the ports table, when executing
5075 the compiler with no port specified on command line, a default
5076 port is selected with the new macro DEFAULT_PORT which is
5077 defined in port.h, in setDefaultOptions() linkOptions is removed
5078 from initialization assignment, since now it is a set,
5079 parseCmdLine uses setParseWithComma for linkOptions, in
5080 linkEdit() linkOptions are accessed with new function indexSet()
5081 which returns the i'th item of a set variable. See SDCCset.c, in
5082 linkEdit() when calling buildCmdLine(), added linkOptions as
5083 last argument. Now users can pass arguments to gplink via the
5084 -Wl option, main() uses pic16glue() to glue up pic16 programs

5098 gpasm complaining and test the linkage with gplink, _linkCmd and
5099 _asmCmd changed to be more gplink and gpasm friendly
5100 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5101 produced an error when parsed, peep rule 12 is added to utilize
5102 movff, but it is commented out since the pCode does not support
5103 yet a command with 2 address arguments
5105 2003-05-18 <johan AT balder>
5107 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5134 2003-05-11 Borut Razem <borut.razem AT siol.net>
5136 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6136 2003-01-06 <karl AT turbobit.com>
6137 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
6140 2003-01-06 <johan AT balder>
6142 * src/SDCCicode.c: fixed array add
6144 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6145 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6146 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6148 2003-01-04 <johan AT balder>
6150 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6152 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6153 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6155 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6156 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6157 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6159 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6160 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6162 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6163 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6165 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6166 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6168 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6170 * in \sdcc\as\mcs51\ changed these files in order to create an
6171 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6172 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6173 following files to include the previous two files: aslink.dsp,
6174 Makefile.aslink, Makefile.bcc, and Makefile.in.
6176 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6177 .adb instead of .cdb
6179 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6181 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6182 value from option --iram-size.
6184 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6186 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6189 2002-09-18 <wiml AT hhhh.org>
6191 * SDCClrange.h: exposed setFromRange() and setToRange()
6192 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6193 packRegsForAccUse() (bug 542397)
6194 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6195 multiple times and emitting the fetch operations more than once
6196 added aopGetUsesAcc() function to allow binary operators to
6197 fetch their operands in the correct order; made genMinus() emit
6198 compact code for X = LITERAL - Y
6200 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6201 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6202 sprintf() in line 1267.
6204 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6205 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6208 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6209 Changes to aslink (All the changes are marked with 'JCF'):
6211 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6214 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6215 area BSEG. Also moves, if possible, the DATA area down into the internal
6216 ram so more space is available.
6218 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6221 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6222 not bytes. Function summary() which creates a memory usage summary
6223 file with extension .mem. Reports of overlaping stack and small stack
6224 size. If the space for the stack is less than 16 bytes aslink trows a
6227 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6228 the 8051. Option 'y' for memory summary output file.
6230 Changes to sdcc (All the changes are marked with 'JCF'):
6232 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6234 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6235 overlaying area for it (uses RegBankUsed[4]).
6237 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6238 bank zero as used by default. By default aslink locates the stack
6239 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6240 the creation of the .mem file. Delegates the allocation of data area
6241 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6242 the begining of the stack area to aslink.
6244 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6245 glue() in SDCCglue.c creates an area for it.
6247 2002-09-03 Borut Razem <borut.razem AT siol.net>
6248 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6249 sdcc/src/pic/glue.c:
6250 introduced atexit() handler for teporay files removal in case of
6251 errors, assertions, ...
6253 2002-08-29 Borut Razem <borut.razem AT siol.net>
6254 * sdcc/support/cpp2/auto-host_vc_in.h:
6255 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6256 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6257 Maybe there is a similar problem with BORLANDC? It should be checked!
6259 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6260 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6261 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6262 was not executed, and the compiler (cl) launched a warning:
6263 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6265 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6266 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6268 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6269 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6271 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6272 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6273 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6274 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6275 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6276 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6277 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6278 - added Release configuration in VS projects
6279 - review of compiler an linker options
6280 - VC .exe files are generated in bin_vc directory, not to interfere
6281 with binaries generated from other projects (cygwin, mingw, bcc ...)
6283 * sdcc/src/yacc.dsp: added
6285 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6286 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6287 and insert the version number definitions from .version
6289 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6291 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6292 added - genarate auto-host.h using auto-host_vc_in.h as template
6295 removed from CVS, generated automatically
6297 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6298 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6300 2002-08-11 Borut Razem <borut.razem AT siol.net>
6301 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6303 2002-08-10 Borut Razem <borut.razem AT siol.net>
6304 * src/SDCCmain.c (main):
6305 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6306 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6307 The consequence was that some temporary files were not removed.
6310 unification of code in functions tempfilename() and tempfile():
6311 function tempnam() is defined in Visual Studio 6.0 and .NET
6313 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6315 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6316 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6317 - removed compiler command line option /WX: Treats all warnings as errors
6318 - update a list of source files, included into the project
6320 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6321 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6322 changed project type to Generic Project so that can be correcly converted to VS.NET project
6324 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6326 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6328 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6330 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6331 added return 0 statements after assert() to make compiler happy
6333 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6334 added newline in the def file to keep MSC compiler satisfied
6336 * sdcc/src/z80/gen.c:
6337 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6338 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6339 - solved MSC error in function aopDump()
6341 * sdcc_vc.h: define PREFIX as "\\sdcc"
6343 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6344 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6383 2002-03-28 Johan Knol <johan AT balder>
6385 * src/SDCCval.c: fixed bug #532436
6387 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6389 Added "char *Processor" field to the port structure.
6392 Added -p option. Allows port dependent processor to be specified.
6395 Initialized the new field char *Processor field to NULL in all ports
6398 Compiler generated registers for interrupt context saving
6399 were not getting allocated.
6401 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6404 Fixed left shift. Will promote the left side of a left shift
6405 if a) left shifting more than size of operand or b) when assigned
6406 to something size > size of left side
6408 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6410 tons of changes. Register allocation has been
6411 rewritten. Added customization for the various PICs. Flow
6412 analysis is restructured. ...
6418 Added. device.c is a PIC port hack to accomodate variations
6421 2002-03-13 Michael Hope <michaelh AT vroom>
6423 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

6516 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6518 * sdcc/src/SDCCloop.c:
6519 Previous fix was not good. basic blocks that have "break" or "return" are
6520 not really partof a loop , but live ranges used in these blocks should
6521 be live thru the entire loop, so set partOfLoop but don't add them to
6524 2002-02-21 <johan AT FRIJA>
6526 * src/SDCCcse.c: fixed bug #514308
6528 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6531 Fixed BUG #519583. If a conditional block ended in a return/break
6532 statement inside a loop, it was not being considered part of the loop.
6534 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6536 2002-02-10 Karl Bongers <karl AT turbobit.com>
6539 Fixed up SDCDB debugger somewhat. Updated debugger/README
6540 with lots of comments and notes.
6542 * device/examples/test2.c:
6543 Fix bug, "red" variable not being initialized(compiler complained).
6545 * device/examples/Makefile, examples/test3.c:
6546 Add Makefile in device/examples folder, compiles test3.c
6547 for use as a multiple module SDCDB test case.
6549 * sim/ucsim/cmd.src/cmdset.cc:
6550 Took out debug printfs in ucsim "next" command.
6553 Karl and Johan start ucsim XA support. Most dissassembly working,
6554 about 75% emulation done(plenty of work remaining).
6556 * sim/ucsim/z80.src:
6557 Add Z80 support to ucsim, add test-ucz80 regression test,
6558 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6559 Notice z80 compiler fails on examples/test3.c/crc code.

6580 changes to handle multiple sends & receives
6583 added some pointer arithmetic optimization
6586 added some pointer arithmetic optimizations but not stable yet so not
6587 called from anywhere (will get this working shortly)

6592 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
6593 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
6594 set preprocessor defines (depending on options)
6596 * src/SDCCicode.c, src/SDCCicode.h:
6597 changes made to handle multiple sends & receives
6600 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
