2939 loaded with the linker search paths (-L arguments) and the libraries
2940 to be linked with the current source (-l arguments). Changes
2941 currently will affect only the pic16 port.
2942 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2943 include path the port specific paths and port specific libraries,
2944 * gplink command now contains the $3 argument,
2945 * src/pic16/device.h,

2962 Documenting changes from previous commits.
2963 * configure.in (version 1.56),
2964 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2965 when generating output files to configure the pic16 library,
2966 but now I've commented it out, since gputils aren't installed in the
2967 SF compile farm, so library won't compile
2969 * device/lib/Makefile.in (version 1.56): initially I've added in
2970 target 'all' the prerequestive 'model-pic16' so it compiled the
2971 pic16 library, but now I've commented it out for the same reasons
2973 * added targets 'model-pic16' and 'objects-pic16' to compile the
2975 * added target 'port-specific-objects-pic16' to handle the
2976 generated libraries and copy them into the build/ directory
2977 * added target 'clean-intermediate-pic16' to clean intermediate
2978 files into pic16 directory
2979 * in target 'installdirs' added line to create directory pic16 in

2983 added lines to copy all header files to installation path,
2984 * in target 'installdirs' added line create directory for pic16
2985 headers in the installation path

3226 LEFT_OP (left shift)
3228 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3230 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3231 (default behaviour).
3233 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3235 A python script to validate compiler diagnostic messages. It can be
3236 used to verify that sdcc complains about bad c source code and
3237 gives a good location of the error.
3238 * support/valdiag/Makefile,
3239 * support/valdiag/valdiag.py,
3240 * support/valdiag/tests/*

3257 Bug reported from Jesus Calvino-Fraga
3259 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3261 * sdcc.spec: updated
3262 * device/include/Makefile.in: don't install CVS directories
3263 * device/lib/Makefile.in: added removal of CVS directories after install
3264 * doc/Makefile: fixed install, added local_icons
3265 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3266 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3267 * src/ds390/gen.c (genRightShift): fixed bug #870788
3268 * src/SDCCast.c (decorateType): fixed bug #870781
3270 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3272 PIC16 port related changes:
3273 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3274 added variable stackPos,
3276 * gen.c: genCall, assignResultValue: added support for
3277 pushing/retrieving function parameters to/from stack,
3278 genFunction,genEndFunction: setup stack frame for the
3280 genAddrOf: will be changed according to bug 863624
3282 * added files genutils.c and genutils.h which contain gen*
3283 debugged and optimised functions extracted from gen.c
3285 * glue.c: added variable 'externs' which holds extern symbols,
3286 pic16emitRegularMap: is modified to properly handle relocatable
3287 symbols under the new scheme,
3288 pic16createInterruptVect: is modified
3289 pic16printPublics: is modified to emit 'global' assembler directives,
3290 added pic16_printExterns to print extern symbols,
3291 pic16glue: initializes stack/frame pointer in the beginning of
3292 the assembly output. Temporary hack, will be corrected later,
3293 because gplink yet does not support stack and SDCC does not
3294 yet support a type of crt0.o object to create the final binary.
3296 * Removed many lines that contain 8051 legacy code.
3297 * The code is finally placed under a 'code' directive.
3298 * Added port specific options.
3300 * _process_pragma: simplified since now we do not need *special*
3301 include file to define SFR registers. But a separate header
3302 will be needed. This will be developed later.
3303 * _pic16_parseOptions: added, parses port specific options:
3304 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3305 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3306 --preplace-udata-with=
3308 * _pic16_setDefaultOptions: modified to initialize section names,
3309 but hack is temporarly out of order since it needs improvement.
3310 * _pic16_genAssemblerPreamble: configuration words are emitted by
3311 their address instead of their name. This part is incomplete and
3312 supports only the 18Fxx2 devices. Other devices will emit an error
3313 during assembly since they do not contain the same set of config
3315 * _pic16_genIVT: is modified,
3317 * pcode.c: added definitions for some hardware registers that are needed
3319 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3320 All PCI entries are updated. Now LFSR is supported.
3321 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3322 * added pic16_newpCodeOpLit2 to support instructions with
3323 two literal arguments
3324 * pic16_pCode2str: corrected code that emits assembler instructions
3325 with two literal operands and those that have an access bit modifier
3326 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3327 this fixes a bug which caused some labels to be lost, when an
3328 assembler directive was added, i.e. banksel,
3329 * pic16_FixRegisterBanking: improved logic that causes the insertion
3331 * InlineFunction: functions that are called once, are not any more
3332 inlined. This can be a port option in the future,
3334 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3336 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3337 hold the corresponding uninitialized symbols,
3338 * pic16_allocProcessorRegister: registers have explicit marked the
3340 * pic16_allocInternalRegister: registers are explicit marked as
3342 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3343 processing list, so bit registers were lost,
3346 * ralloc.h: added field 'accessBank' and original symbol operand
3347 in register definition,
3348 * removed the field isMapped from register definition,
3350 ** Several functions have been removed from various sources:
3351 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3352 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3353 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3354 pic16_assignRelocatableRegisters
3356 ** others have been introduced:
3357 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3358 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3360 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3362 * support/scripts/inc2h.pl: changed definition of BIT_AT
3363 to emit 'sbit at' instead of 'bit at'. This was a request.
3365 PIC16 port related preliminary changes:
3366 * gen.c: prefixed function popRegFromString with
3367 pic16_ and all references to it corrected
3368 * pcode.c: all pic16_pc_* hardware registers prefixed
3369 with underscore (_),
3370 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3371 * ralloc.c: newReg(): when register is REG_SFR then
3372 set address to rIdx,
3373 pic16_allocProcessorRegister(): marks register wasUsed=0
3374 pic16_writeUsedRegs(): added a call to assign processor
3375 registers via pic16_assignFixedRegisters
3377 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3379 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3380 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3381 variables in unused register banks. Also the SSEG is placed
3382 wherever there is enough space for it, and IDATA can be anywhere
3383 in internal RAM. For now compile using -Wl-Y[stack_size].
3384 The mem file is different for this option as well, since it
3385 makes no sense of talking about DSEG lenght.
3387 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3389 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3390 in certain cases, e.g. when ROM assignment, patch provided
3391 from Albert den Haan.
3393 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3632 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3634 * src/SDCCast.c (decorateType): disabled a transformation I added in
3635 revision 1.188 (access to fields of a structure at an absolute address);
3636 it breaks with bitfields, extern declarations, and gcse analysis.
3637 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3638 could be assigned through a pointer, so don't complain.
3639 * src/SDCCast.c (astErrors),
3641 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4278 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4279 support for standard C idiom of memory mapped variables; for
4280 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4281 to xdata int at 0x1234 tempvar = 1.
4282 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4283 provided by Akiya ISHIDA

4299 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4301 Fixed bug #621531 (const & volatile confusion in the type chain).
4302 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

4394 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4395 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4396 fetching of the pointer
4397 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4398 copied from genNearPointerSet()
4399 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4400 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4401 If they pop r0/r1 they must be called in the opposite order than aopOp().
4402 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4403 (resp. --stack-auto), prepared for --xstack

4416 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4417 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4418 type for bits was changed. It resulted in bit variables becoming
4419 global, which is not permitted in PIC 14 assembly output.
4421 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4423 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4436 A few small changes that speed up the peephole optimizer.
4440 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4442 Try to make the peephole optimizer smarter by maintaining
4443 an association between the assembly source code and the
4444 iCodes that originated them. Put this information to use
4445 with a new peephole rule condition "notVolatile" so that
4446 the rules can be aggressive yet still safe.
4451 * src/mcs51/peeph.def
4453 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4457 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4458 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4459 if the left or right operand symbols have the accuse flag set.
4461 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4463 Changed the type of the result of the ! (NOT) operator to char;
4464 previously it returned the same type as the source. This allows
4465 us to eliminate all the genFloatNot functions (all of its target
4466 implementations were very buggy) since !float can use the same

4479 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4480 during interrupts. Ensure WSAVE is located at a shared bank address.
4481 2. Fixed page selection in some places
4482 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4483 the registers name strings.
4484 4. Fixed "signed / unsigned compare" compiler warnings.
4485 5. The PIC port manages its own allocation of the general purpose
4486 registers, but makes no attempt to reuse them. As a result when
4487 compiling it soon runs out of general purpose registers. Some
4488 additional code was added to the files pcode.c and device.c to walk
4489 through the function call tree and rename the registers so that they
4499 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4500 genPlus() & genMinus() when the result is the same as left or right

4506 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4508 Made bitfield a distinct type from bit so that bitfields
4509 convert as per ANSI C and bits retain their traditional
4510 boolean style behaviour. Implemented bitfield support in
4518 * src/ds390/gen.c: bit v bitfield split
4519 * src/z80/gen.c: New support for bitfields
4520 * support/regression/tests/bitfields.c: reenabled z80,
4523 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4525 Rules 246.x, 247.x relate to bitfields, the others speed up
4526 access to xdata mapped I/O devices.
4528 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4530 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4532 Cleaned up genPackBits and genUnpackBits and added two helper
4533 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4534 for literal assignments in genPackBits (thanks to Frieder for
4540 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4542 Fixed bug #748310 (pointer to function type mishandled when the
4543 function name is omitted). Also fixed a SIGSEGV when a function
4544 attribute (reentrant, etc) is used on a non-function or on a
4545 function but misplaced before the parameter list.
4547 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4549 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4550 * support/Util/SDCCerr.h,

4572 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4574 Made the constant following the "interrupt" keyword optional. If
4575 omitted, the function will not automatically be given an entry
4576 in the interrupt vector table (similar to #pragma NOIV, but
4577 less syntacticly kludgy). The interrupt number is also now
4578 range checked. Also fixed a bug in the high order bit example

5109 messages from optionsTable when a port is not configured, added
5110 support for the PIc16 port in the ports table, when executing
5111 the compiler with no port specified on command line, a default
5112 port is selected with the new macro DEFAULT_PORT which is
5113 defined in port.h, in setDefaultOptions() linkOptions is removed
5114 from initialization assignment, since now it is a set,
5115 parseCmdLine uses setParseWithComma for linkOptions, in
5116 linkEdit() linkOptions are accessed with new function indexSet()
5117 which returns the i'th item of a set variable. See SDCCset.c, in
5118 linkEdit() when calling buildCmdLine(), added linkOptions as
5119 last argument. Now users can pass arguments to gplink via the
5120 -Wl option, main() uses pic16glue() to glue up pic16 programs

5134 gpasm complaining and test the linkage with gplink, _linkCmd and
5135 _asmCmd changed to be more gplink and gpasm friendly
5136 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5137 produced an error when parsed, peep rule 12 is added to utilize
5138 movff, but it is commented out since the pCode does not support
5139 yet a command with 2 address arguments
5141 2003-05-18 <johan AT balder>

6178 * src/SDCCicode.c: fixed array add
6180 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6181 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6182 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6184 2003-01-04 <johan AT balder>
6186 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6188 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6189 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6191 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6192 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

6201 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6202 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6204 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6206 * in \sdcc\as\mcs51\ changed these files in order to create an
6207 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6208 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6209 following files to include the previous two files: aslink.dsp,
6210 Makefile.aslink, Makefile.bcc, and Makefile.in.
6212 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6213 .adb instead of .cdb
6215 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6217 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6218 value from option --iram-size.
6220 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6222 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6225 2002-09-18 <wiml AT hhhh.org>
6227 * SDCClrange.h: exposed setFromRange() and setToRange()
6228 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6229 packRegsForAccUse() (bug 542397)
6230 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6231 multiple times and emitting the fetch operations more than once
6232 added aopGetUsesAcc() function to allow binary operators to
6233 fetch their operands in the correct order; made genMinus() emit
6234 compact code for X = LITERAL - Y
6236 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6237 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6238 sprintf() in line 1267.
6240 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6241 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6244 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6245 Changes to aslink (All the changes are marked with 'JCF'):
6247 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6250 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6251 area BSEG. Also moves, if possible, the DATA area down into the internal
6252 ram so more space is available.
6254 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6257 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6258 not bytes. Function summary() which creates a memory usage summary
6259 file with extension .mem. Reports of overlaping stack and small stack
6260 size. If the space for the stack is less than 16 bytes aslink trows a
6263 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6264 the 8051. Option 'y' for memory summary output file.
6266 Changes to sdcc (All the changes are marked with 'JCF'):
6268 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6270 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6271 overlaying area for it (uses RegBankUsed[4]).
6273 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6274 bank zero as used by default. By default aslink locates the stack
6275 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6276 the creation of the .mem file. Delegates the allocation of data area
6277 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6278 the begining of the stack area to aslink.
6280 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6281 glue() in SDCCglue.c creates an area for it.
6283 2002-09-03 Borut Razem <borut.razem AT siol.net>
6284 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6285 sdcc/src/pic/glue.c:
6286 introduced atexit() handler for teporay files removal in case of
6287 errors, assertions, ...
6289 2002-08-29 Borut Razem <borut.razem AT siol.net>
6290 * sdcc/support/cpp2/auto-host_vc_in.h:
6291 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6292 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6293 Maybe there is a similar problem with BORLANDC? It should be checked!
6295 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6296 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6297 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6298 was not executed, and the compiler (cl) launched a warning:
6299 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6301 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6302 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6304 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6305 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6307 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6308 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6309 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6310 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6311 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6312 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6313 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6314 - added Release configuration in VS projects
6315 - review of compiler an linker options
6316 - VC .exe files are generated in bin_vc directory, not to interfere
6317 with binaries generated from other projects (cygwin, mingw, bcc ...)
6319 * sdcc/src/yacc.dsp: added
6321 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6322 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6323 and insert the version number definitions from .version
6325 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6327 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6328 added - genarate auto-host.h using auto-host_vc_in.h as template
6331 removed from CVS, generated automatically
6333 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6334 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6336 2002-08-11 Borut Razem <borut.razem AT siol.net>
6337 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6339 2002-08-10 Borut Razem <borut.razem AT siol.net>
6340 * src/SDCCmain.c (main):
6341 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6342 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6343 The consequence was that some temporary files were not removed.
6346 unification of code in functions tempfilename() and tempfile():
6347 function tempnam() is defined in Visual Studio 6.0 and .NET
6349 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6351 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6352 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6353 - removed compiler command line option /WX: Treats all warnings as errors
6354 - update a list of source files, included into the project
6356 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6357 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6358 changed project type to Generic Project so that can be correcly converted to VS.NET project
6360 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6362 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6364 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6366 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6367 added return 0 statements after assert() to make compiler happy
6369 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6370 added newline in the def file to keep MSC compiler satisfied
6372 * sdcc/src/z80/gen.c:
6373 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6374 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6375 - solved MSC error in function aopDump()
6377 * sdcc_vc.h: define PREFIX as "\\sdcc"
6379 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6380 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6419 2002-03-28 Johan Knol <johan AT balder>
6421 * src/SDCCval.c: fixed bug #532436
6423 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6425 Added "char *Processor" field to the port structure.
6428 Added -p option. Allows port dependent processor to be specified.
6431 Initialized the new field char *Processor field to NULL in all ports
6434 Compiler generated registers for interrupt context saving
6435 were not getting allocated.
6437 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6440 Fixed left shift. Will promote the left side of a left shift
6441 if a) left shifting more than size of operand or b) when assigned
6442 to something size > size of left side
6444 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6446 tons of changes. Register allocation has been
6447 rewritten. Added customization for the various PICs. Flow
6448 analysis is restructured. ...
6454 Added. device.c is a PIC port hack to accomodate variations
6457 2002-03-13 Michael Hope <michaelh AT vroom>
6459 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6461 2002-03-04 johanknol <johanknol AT manik>

6468 2002-03-04 bela <bela AT manik>
6470 * /device/include/mcs51reg.h:
6471 ds89c420 register definition update
6473 2002-03-03 <johan AT FRIJA>

6552 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6554 * sdcc/src/SDCCloop.c:
6555 Previous fix was not good. basic blocks that have "break" or "return" are
6556 not really partof a loop , but live ranges used in these blocks should
6557 be live thru the entire loop, so set partOfLoop but don't add them to
6560 2002-02-21 <johan AT FRIJA>
6562 * src/SDCCcse.c: fixed bug #514308
6564 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6567 Fixed BUG #519583. If a conditional block ended in a return/break
6568 statement inside a loop, it was not being considered part of the loop.
6570 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6572 2002-02-10 Karl Bongers <karl AT turbobit.com>
6575 Fixed up SDCDB debugger somewhat. Updated debugger/README
6576 with lots of comments and notes.
6578 * device/examples/test2.c:
6579 Fix bug, "red" variable not being initialized(compiler complained).
6581 * device/examples/Makefile, examples/test3.c:
6582 Add Makefile in device/examples folder, compiles test3.c
6583 for use as a multiple module SDCDB test case.
6585 * sim/ucsim/cmd.src/cmdset.cc:
6586 Took out debug printfs in ucsim "next" command.
6589 Karl and Johan start ucsim XA support. Most dissassembly working,
6590 about 75% emulation done(plenty of work remaining).
6592 * sim/ucsim/z80.src:
6593 Add Z80 support to ucsim, add test-ucz80 regression test,
6594 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6595 Notice z80 compiler fails on examples/test3.c/crc code.
6597 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
6599 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

6602 * src/ds390/peeph.def:
6603 added a few more peephole optimzations
6606 1) added __builtin_inp & __builtin_outp used to read in data of given length
6607 from a memory mapped port
6608 2) added __builtin_memcmp
6609 3) added __builtin_swapw swap bytes of a short
6611 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
6612 1) handle multiple send & receives from register bank1
