2944 loaded with the linker search paths (-L arguments) and the libraries
2945 to be linked with the current source (-l arguments). Changes
2946 currently will affect only the pic16 port.
2947 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2948 include path the port specific paths and port specific libraries,
2949 * gplink command now contains the $3 argument,
2950 * src/pic16/device.h,

2967 Documenting changes from previous commits.
2968 * configure.in (version 1.56),
2969 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2970 when generating output files to configure the pic16 library,
2971 but now I've commented it out, since gputils aren't installed in the
2972 SF compile farm, so library won't compile
2974 * device/lib/Makefile.in (version 1.56): initially I've added in
2975 target 'all' the prerequestive 'model-pic16' so it compiled the
2976 pic16 library, but now I've commented it out for the same reasons
2978 * added targets 'model-pic16' and 'objects-pic16' to compile the
2980 * added target 'port-specific-objects-pic16' to handle the
2981 generated libraries and copy them into the build/ directory
2982 * added target 'clean-intermediate-pic16' to clean intermediate
2983 files into pic16 directory
2984 * in target 'installdirs' added line to create directory pic16 in

2988 added lines to copy all header files to installation path,
2989 * in target 'installdirs' added line create directory for pic16
2990 headers in the installation path

3229 * src/SDCCast.c (decorateType),
3230 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3231 LEFT_OP (left shift)
3233 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3235 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3236 (default behaviour).
3238 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3240 A python script to validate compiler diagnostic messages. It can be
3241 used to verify that sdcc complains about bad c source code and
3242 gives a good location of the error.
3243 * support/valdiag/Makefile,
3244 * support/valdiag/valdiag.py,
3245 * support/valdiag/tests/*
3247 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3258 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3260 * src/common.h: added ifndef/define/endif macros
3261 around the header file.
3262 Bug reported from Jesus Calvino-Fraga
3264 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3266 * sdcc.spec: updated
3267 * device/include/Makefile.in: don't install CVS directories
3268 * device/lib/Makefile.in: added removal of CVS directories after install
3269 * doc/Makefile: fixed install, added local_icons
3270 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3271 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3272 * src/ds390/gen.c (genRightShift): fixed bug #870788
3273 * src/SDCCast.c (decorateType): fixed bug #870781
3275 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3277 PIC16 port related changes:
3278 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3279 added variable stackPos,
3281 * gen.c: genCall, assignResultValue: added support for
3282 pushing/retrieving function parameters to/from stack,
3283 genFunction,genEndFunction: setup stack frame for the
3285 genAddrOf: will be changed according to bug 863624
3287 * added files genutils.c and genutils.h which contain gen*
3288 debugged and optimised functions extracted from gen.c
3290 * glue.c: added variable 'externs' which holds extern symbols,
3291 pic16emitRegularMap: is modified to properly handle relocatable
3292 symbols under the new scheme,
3293 pic16createInterruptVect: is modified
3294 pic16printPublics: is modified to emit 'global' assembler directives,
3295 added pic16_printExterns to print extern symbols,
3296 pic16glue: initializes stack/frame pointer in the beginning of
3297 the assembly output. Temporary hack, will be corrected later,
3298 because gplink yet does not support stack and SDCC does not
3299 yet support a type of crt0.o object to create the final binary.
3301 * Removed many lines that contain 8051 legacy code.
3302 * The code is finally placed under a 'code' directive.
3303 * Added port specific options.
3305 * _process_pragma: simplified since now we do not need *special*
3306 include file to define SFR registers. But a separate header
3307 will be needed. This will be developed later.
3308 * _pic16_parseOptions: added, parses port specific options:
3309 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3310 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3311 --preplace-udata-with=
3313 * _pic16_setDefaultOptions: modified to initialize section names,
3314 but hack is temporarly out of order since it needs improvement.
3315 * _pic16_genAssemblerPreamble: configuration words are emitted by
3316 their address instead of their name. This part is incomplete and
3317 supports only the 18Fxx2 devices. Other devices will emit an error
3318 during assembly since they do not contain the same set of config
3320 * _pic16_genIVT: is modified,
3322 * pcode.c: added definitions for some hardware registers that are needed
3324 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3325 All PCI entries are updated. Now LFSR is supported.
3326 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3327 * added pic16_newpCodeOpLit2 to support instructions with
3328 two literal arguments
3329 * pic16_pCode2str: corrected code that emits assembler instructions
3330 with two literal operands and those that have an access bit modifier
3331 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3332 this fixes a bug which caused some labels to be lost, when an
3333 assembler directive was added, i.e. banksel,
3334 * pic16_FixRegisterBanking: improved logic that causes the insertion
3336 * InlineFunction: functions that are called once, are not any more
3337 inlined. This can be a port option in the future,
3339 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3341 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3342 hold the corresponding uninitialized symbols,
3343 * pic16_allocProcessorRegister: registers have explicit marked the
3345 * pic16_allocInternalRegister: registers are explicit marked as
3347 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3348 processing list, so bit registers were lost,
3351 * ralloc.h: added field 'accessBank' and original symbol operand
3352 in register definition,
3353 * removed the field isMapped from register definition,
3355 ** Several functions have been removed from various sources:
3356 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3357 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3358 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3359 pic16_assignRelocatableRegisters
3361 ** others have been introduced:
3362 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3363 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3365 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3367 * support/scripts/inc2h.pl: changed definition of BIT_AT
3368 to emit 'sbit at' instead of 'bit at'. This was a request.
3370 PIC16 port related preliminary changes:
3371 * gen.c: prefixed function popRegFromString with
3372 pic16_ and all references to it corrected
3373 * pcode.c: all pic16_pc_* hardware registers prefixed
3374 with underscore (_),
3375 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3376 * ralloc.c: newReg(): when register is REG_SFR then
3377 set address to rIdx,
3378 pic16_allocProcessorRegister(): marks register wasUsed=0
3379 pic16_writeUsedRegs(): added a call to assign processor
3380 registers via pic16_assignFixedRegisters
3382 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3384 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3385 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3386 variables in unused register banks. Also the SSEG is placed
3387 wherever there is enough space for it, and IDATA can be anywhere
3388 in internal RAM. For now compile using -Wl-Y[stack_size].
3389 The mem file is different for this option as well, since it
3390 makes no sense of talking about DSEG lenght.
3392 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3394 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3395 in certain cases, e.g. when ROM assignment, patch provided
3396 from Albert den Haan.
3398 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3637 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3639 * src/SDCCast.c (decorateType): disabled a transformation I added in
3640 revision 1.188 (access to fields of a structure at an absolute address);
3641 it breaks with bitfields, extern declarations, and gcse analysis.
3642 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3643 could be assigned through a pointer, so don't complain.
3644 * src/SDCCast.c (astErrors),
3646 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4283 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4284 support for standard C idiom of memory mapped variables; for
4285 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4286 to xdata int at 0x1234 tempvar = 1.
4287 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

4304 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4306 Fixed bug #621531 (const & volatile confusion in the type chain).
4307 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4399 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4400 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4401 fetching of the pointer
4402 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4403 copied from genNearPointerSet()
4404 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4405 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4406 If they pop r0/r1 they must be called in the opposite order than aopOp().
4407 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4408 (resp. --stack-auto), prepared for --xstack

4419 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4421 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4422 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4423 type for bits was changed. It resulted in bit variables becoming
4424 global, which is not permitted in PIC 14 assembly output.
4426 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4428 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4441 A few small changes that speed up the peephole optimizer.
4445 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4447 Try to make the peephole optimizer smarter by maintaining
4448 an association between the assembly source code and the
4449 iCodes that originated them. Put this information to use
4450 with a new peephole rule condition "notVolatile" so that
4451 the rules can be aggressive yet still safe.
4456 * src/mcs51/peeph.def
4458 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4462 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4463 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4464 if the left or right operand symbols have the accuse flag set.
4466 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4468 Changed the type of the result of the ! (NOT) operator to char;
4469 previously it returned the same type as the source. This allows
4470 us to eliminate all the genFloatNot functions (all of its target
4471 implementations were very buggy) since !float can use the same

4483 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4484 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4485 during interrupts. Ensure WSAVE is located at a shared bank address.
4486 2. Fixed page selection in some places
4487 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4488 the registers name strings.
4489 4. Fixed "signed / unsigned compare" compiler warnings.
4490 5. The PIC port manages its own allocation of the general purpose
4491 registers, but makes no attempt to reuse them. As a result when
4492 compiling it soon runs out of general purpose registers. Some
4493 additional code was added to the files pcode.c and device.c to walk
4494 through the function call tree and rename the registers so that they
4504 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4505 genPlus() & genMinus() when the result is the same as left or right

4511 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4513 Made bitfield a distinct type from bit so that bitfields
4514 convert as per ANSI C and bits retain their traditional
4515 boolean style behaviour. Implemented bitfield support in
4523 * src/ds390/gen.c: bit v bitfield split
4524 * src/z80/gen.c: New support for bitfields
4525 * support/regression/tests/bitfields.c: reenabled z80,
4528 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4530 Rules 246.x, 247.x relate to bitfields, the others speed up
4531 access to xdata mapped I/O devices.
4533 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4535 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4537 Cleaned up genPackBits and genUnpackBits and added two helper
4538 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4539 for literal assignments in genPackBits (thanks to Frieder for
4545 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4547 Fixed bug #748310 (pointer to function type mishandled when the
4548 function name is omitted). Also fixed a SIGSEGV when a function
4549 attribute (reentrant, etc) is used on a non-function or on a
4550 function but misplaced before the parameter list.
4552 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4554 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4555 * support/Util/SDCCerr.h,

4577 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4579 Made the constant following the "interrupt" keyword optional. If
4580 omitted, the function will not automatically be given an entry
4581 in the interrupt vector table (similar to #pragma NOIV, but
4582 less syntacticly kludgy). The interrupt number is also now
4583 range checked. Also fixed a bug in the high order bit example

4599 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4601 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4602 be re-activated by defining REDUCE_LITERALS)

4604 unsigned, but are signed by default
4605 * src/SDCCval.c (constVal): rearranged
4606 * src/SDCCval.c (valMod): preliminary fix
4607 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5114 messages from optionsTable when a port is not configured, added
5115 support for the PIc16 port in the ports table, when executing
5116 the compiler with no port specified on command line, a default
5117 port is selected with the new macro DEFAULT_PORT which is
5118 defined in port.h, in setDefaultOptions() linkOptions is removed
5119 from initialization assignment, since now it is a set,
5120 parseCmdLine uses setParseWithComma for linkOptions, in
5121 linkEdit() linkOptions are accessed with new function indexSet()
5122 which returns the i'th item of a set variable. See SDCCset.c, in
5123 linkEdit() when calling buildCmdLine(), added linkOptions as
5124 last argument. Now users can pass arguments to gplink via the
5125 -Wl option, main() uses pic16glue() to glue up pic16 programs

5139 gpasm complaining and test the linkage with gplink, _linkCmd and
5140 _asmCmd changed to be more gplink and gpasm friendly
5141 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5142 produced an error when parsed, peep rule 12 is added to utilize
5143 movff, but it is commented out since the pCode does not support
5144 yet a command with 2 address arguments
5146 2003-05-18 <johan AT balder>

6183 * src/SDCCicode.c: fixed array add
6185 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6186 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6187 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6189 2003-01-04 <johan AT balder>
6191 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6193 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6194 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6196 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

6206 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6207 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6209 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6211 * in \sdcc\as\mcs51\ changed these files in order to create an
6212 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6213 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6214 following files to include the previous two files: aslink.dsp,
6215 Makefile.aslink, Makefile.bcc, and Makefile.in.
6217 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6218 .adb instead of .cdb
6220 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6222 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6223 value from option --iram-size.
6225 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6227 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6230 2002-09-18 <wiml AT hhhh.org>
6232 * SDCClrange.h: exposed setFromRange() and setToRange()
6233 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6234 packRegsForAccUse() (bug 542397)
6235 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6236 multiple times and emitting the fetch operations more than once
6237 added aopGetUsesAcc() function to allow binary operators to
6238 fetch their operands in the correct order; made genMinus() emit
6239 compact code for X = LITERAL - Y
6241 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6242 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6243 sprintf() in line 1267.
6245 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6246 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6249 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6250 Changes to aslink (All the changes are marked with 'JCF'):
6252 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6255 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6256 area BSEG. Also moves, if possible, the DATA area down into the internal
6257 ram so more space is available.
6259 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6262 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6263 not bytes. Function summary() which creates a memory usage summary
6264 file with extension .mem. Reports of overlaping stack and small stack
6265 size. If the space for the stack is less than 16 bytes aslink trows a
6268 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6269 the 8051. Option 'y' for memory summary output file.
6271 Changes to sdcc (All the changes are marked with 'JCF'):
6273 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6275 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6276 overlaying area for it (uses RegBankUsed[4]).
6278 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6279 bank zero as used by default. By default aslink locates the stack
6280 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6281 the creation of the .mem file. Delegates the allocation of data area
6282 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6283 the begining of the stack area to aslink.
6285 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6286 glue() in SDCCglue.c creates an area for it.
6288 2002-09-03 Borut Razem <borut.razem AT siol.net>
6289 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6290 sdcc/src/pic/glue.c:
6291 introduced atexit() handler for teporay files removal in case of
6292 errors, assertions, ...
6294 2002-08-29 Borut Razem <borut.razem AT siol.net>
6295 * sdcc/support/cpp2/auto-host_vc_in.h:
6296 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6297 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6298 Maybe there is a similar problem with BORLANDC? It should be checked!
6300 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6301 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6302 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6303 was not executed, and the compiler (cl) launched a warning:
6304 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6306 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6307 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6309 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6310 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6312 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6313 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6314 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6315 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6316 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6317 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6318 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6319 - added Release configuration in VS projects
6320 - review of compiler an linker options
6321 - VC .exe files are generated in bin_vc directory, not to interfere
6322 with binaries generated from other projects (cygwin, mingw, bcc ...)
6324 * sdcc/src/yacc.dsp: added
6326 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6327 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6328 and insert the version number definitions from .version
6330 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6332 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6333 added - genarate auto-host.h using auto-host_vc_in.h as template
6336 removed from CVS, generated automatically
6338 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6339 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6341 2002-08-11 Borut Razem <borut.razem AT siol.net>
6342 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6344 2002-08-10 Borut Razem <borut.razem AT siol.net>
6345 * src/SDCCmain.c (main):
6346 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6347 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6348 The consequence was that some temporary files were not removed.
6351 unification of code in functions tempfilename() and tempfile():
6352 function tempnam() is defined in Visual Studio 6.0 and .NET
6354 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6356 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6357 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6358 - removed compiler command line option /WX: Treats all warnings as errors
6359 - update a list of source files, included into the project
6361 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6362 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6363 changed project type to Generic Project so that can be correcly converted to VS.NET project
6365 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6367 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6369 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6371 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6372 added return 0 statements after assert() to make compiler happy
6374 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6375 added newline in the def file to keep MSC compiler satisfied
6377 * sdcc/src/z80/gen.c:
6378 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6379 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6380 - solved MSC error in function aopDump()
6382 * sdcc_vc.h: define PREFIX as "\\sdcc"
6384 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6385 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6388 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6389 - Rewrote the register banking algorithm.
6390 - Added pCode live-range analysis to registers (for now, only non-used and
6391 singly-used registers optimized away)
6393 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6395 * 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.

6422 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6424 2002-03-28 Johan Knol <johan AT balder>
6426 * src/SDCCval.c: fixed bug #532436
6428 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6430 Added "char *Processor" field to the port structure.
6433 Added -p option. Allows port dependent processor to be specified.
6436 Initialized the new field char *Processor field to NULL in all ports
6439 Compiler generated registers for interrupt context saving
6440 were not getting allocated.
6442 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6445 Fixed left shift. Will promote the left side of a left shift
6446 if a) left shifting more than size of operand or b) when assigned
6447 to something size > size of left side
6449 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6451 tons of changes. Register allocation has been
6452 rewritten. Added customization for the various PICs. Flow
6453 analysis is restructured. ...
6459 Added. device.c is a PIC port hack to accomodate variations
6462 2002-03-13 Michael Hope <michaelh AT vroom>
6464 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6466 2002-03-04 johanknol <johanknol AT manik>

6473 2002-03-04 bela <bela AT manik>
6475 * /device/include/mcs51reg.h:
6476 ds89c420 register definition update
6478 2002-03-03 <johan AT FRIJA>

6557 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6559 * sdcc/src/SDCCloop.c:
6560 Previous fix was not good. basic blocks that have "break" or "return" are
6561 not really partof a loop , but live ranges used in these blocks should
6562 be live thru the entire loop, so set partOfLoop but don't add them to
6565 2002-02-21 <johan AT FRIJA>
6567 * src/SDCCcse.c: fixed bug #514308
6569 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6572 Fixed BUG #519583. If a conditional block ended in a return/break
6573 statement inside a loop, it was not being considered part of the loop.
6575 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6577 2002-02-10 Karl Bongers <karl AT turbobit.com>
6580 Fixed up SDCDB debugger somewhat. Updated debugger/README
6581 with lots of comments and notes.
6583 * device/examples/test2.c:
6584 Fix bug, "red" variable not being initialized(compiler complained).
6586 * device/examples/Makefile, examples/test3.c:
6587 Add Makefile in device/examples folder, compiles test3.c
6588 for use as a multiple module SDCDB test case.
6590 * sim/ucsim/cmd.src/cmdset.cc:
6591 Took out debug printfs in ucsim "next" command.
6594 Karl and Johan start ucsim XA support. Most dissassembly working,
6595 about 75% emulation done(plenty of work remaining).
6597 * sim/ucsim/z80.src:
6598 Add Z80 support to ucsim, add test-ucz80 regression test,
6599 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6600 Notice z80 compiler fails on examples/test3.c/crc code.
6602 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
6604 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

6607 * src/ds390/peeph.def:
6608 added a few more peephole optimzations
6611 1) added __builtin_inp & __builtin_outp used to read in data of given length
6612 from a memory mapped port
6613 2) added __builtin_memcmp
6614 3) added __builtin_swapw swap bytes of a short
6616 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
6617 1) handle multiple send & receives from register bank1
