2920 loaded with the linker search paths (-L arguments) and the libraries
2921 to be linked with the current source (-l arguments). Changes
2922 currently will affect only the pic16 port.
2923 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2924 include path the port specific paths and port specific libraries,
2925 * gplink command now contains the $3 argument,

2943 Documenting changes from previous commits.
2944 * configure.in (version 1.56),
2945 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2946 when generating output files to configure the pic16 library,
2947 but now I've commented it out, since gputils aren't installed in the
2948 SF compile farm, so library won't compile
2950 * device/lib/Makefile.in (version 1.56): initially I've added in
2951 target 'all' the prerequestive 'model-pic16' so it compiled the
2952 pic16 library, but now I've commented it out for the same reasons
2954 * added targets 'model-pic16' and 'objects-pic16' to compile the
2956 * added target 'port-specific-objects-pic16' to handle the
2957 generated libraries and copy them into the build/ directory
2958 * added target 'clean-intermediate-pic16' to clean intermediate
2959 files into pic16 directory
2960 * in target 'installdirs' added line to create directory pic16 in

2964 added lines to copy all header files to installation path,
2965 * in target 'installdirs' added line create directory for pic16
2966 headers in the installation path

3198 * as/mcs51/lkarea.c: Fixed gcc warnings
3200 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3202 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
3204 * support/valdiag/tests/overflow.c: added
3205 * src/SDCCast.c (decorateType),
3206 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3207 LEFT_OP (left shift)
3209 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3211 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3212 (default behaviour).
3214 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3216 A python script to validate compiler diagnostic messages. It can be
3217 used to verify that sdcc complains about bad c source code and
3218 gives a good location of the error.
3219 * support/valdiag/Makefile,
3220 * support/valdiag/valdiag.py,
3221 * support/valdiag/tests/*
3223 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3225 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3226 * src/SDCCsymt.c (newEnumType),
3228 * support/Util/SDCCerr.c,
3229 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3231 * support/regression/tests/enum.c: added test for enum values that
3232 require at least 2 bytes of storage.
3234 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3236 * src/common.h: added ifndef/define/endif macros
3237 around the header file.
3238 Bug reported from Jesus Calvino-Fraga
3240 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3242 * sdcc.spec: updated
3243 * device/include/Makefile.in: don't install CVS directories
3244 * device/lib/Makefile.in: added removal of CVS directories after install
3245 * doc/Makefile: fixed install, added local_icons
3246 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3247 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3248 * src/ds390/gen.c (genRightShift): fixed bug #870788
3249 * src/SDCCast.c (decorateType): fixed bug #870781
3251 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3253 PIC16 port related changes:
3254 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3255 added variable stackPos,
3257 * gen.c: genCall, assignResultValue: added support for
3258 pushing/retrieving function parameters to/from stack,
3259 genFunction,genEndFunction: setup stack frame for the
3261 genAddrOf: will be changed according to bug 863624
3263 * added files genutils.c and genutils.h which contain gen*
3264 debugged and optimised functions extracted from gen.c
3266 * glue.c: added variable 'externs' which holds extern symbols,
3267 pic16emitRegularMap: is modified to properly handle relocatable
3268 symbols under the new scheme,
3269 pic16createInterruptVect: is modified
3270 pic16printPublics: is modified to emit 'global' assembler directives,
3271 added pic16_printExterns to print extern symbols,
3272 pic16glue: initializes stack/frame pointer in the beginning of
3273 the assembly output. Temporary hack, will be corrected later,
3274 because gplink yet does not support stack and SDCC does not
3275 yet support a type of crt0.o object to create the final binary.
3277 * Removed many lines that contain 8051 legacy code.
3278 * The code is finally placed under a 'code' directive.
3279 * Added port specific options.
3281 * _process_pragma: simplified since now we do not need *special*
3282 include file to define SFR registers. But a separate header
3283 will be needed. This will be developed later.
3284 * _pic16_parseOptions: added, parses port specific options:
3285 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3286 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3287 --preplace-udata-with=
3289 * _pic16_setDefaultOptions: modified to initialize section names,
3290 but hack is temporarly out of order since it needs improvement.
3291 * _pic16_genAssemblerPreamble: configuration words are emitted by
3292 their address instead of their name. This part is incomplete and
3293 supports only the 18Fxx2 devices. Other devices will emit an error
3294 during assembly since they do not contain the same set of config
3296 * _pic16_genIVT: is modified,
3298 * pcode.c: added definitions for some hardware registers that are needed
3300 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3301 All PCI entries are updated. Now LFSR is supported.
3302 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3303 * added pic16_newpCodeOpLit2 to support instructions with
3304 two literal arguments
3305 * pic16_pCode2str: corrected code that emits assembler instructions
3306 with two literal operands and those that have an access bit modifier
3307 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3308 this fixes a bug which caused some labels to be lost, when an
3309 assembler directive was added, i.e. banksel,
3310 * pic16_FixRegisterBanking: improved logic that causes the insertion
3312 * InlineFunction: functions that are called once, are not any more
3313 inlined. This can be a port option in the future,
3315 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3317 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3318 hold the corresponding uninitialized symbols,
3319 * pic16_allocProcessorRegister: registers have explicit marked the
3321 * pic16_allocInternalRegister: registers are explicit marked as
3323 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3324 processing list, so bit registers were lost,
3327 * ralloc.h: added field 'accessBank' and original symbol operand
3328 in register definition,
3329 * removed the field isMapped from register definition,
3331 ** Several functions have been removed from various sources:
3332 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3333 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3334 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3335 pic16_assignRelocatableRegisters
3337 ** others have been introduced:
3338 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3339 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3341 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3343 * support/scripts/inc2h.pl: changed definition of BIT_AT
3344 to emit 'sbit at' instead of 'bit at'. This was a request.
3346 PIC16 port related preliminary changes:
3347 * gen.c: prefixed function popRegFromString with
3348 pic16_ and all references to it corrected
3349 * pcode.c: all pic16_pc_* hardware registers prefixed
3350 with underscore (_),
3351 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3352 * ralloc.c: newReg(): when register is REG_SFR then
3353 set address to rIdx,
3354 pic16_allocProcessorRegister(): marks register wasUsed=0
3355 pic16_writeUsedRegs(): added a call to assign processor
3356 registers via pic16_assignFixedRegisters
3358 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3360 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3361 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3362 variables in unused register banks. Also the SSEG is placed
3363 wherever there is enough space for it, and IDATA can be anywhere
3364 in internal RAM. For now compile using -Wl-Y[stack_size].
3365 The mem file is different for this option as well, since it
3366 makes no sense of talking about DSEG lenght.
3368 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3370 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3371 in certain cases, e.g. when ROM assignment, patch provided
3372 from Albert den Haan.
3374 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3517 * src/mcs51/peephole.def,
3518 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

3530 multiply defined with mismatching "at" address.
3532 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3534 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

3613 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3615 * src/SDCCast.c (decorateType): disabled a transformation I added in
3616 revision 1.188 (access to fields of a structure at an absolute address);
3617 it breaks with bitfields, extern declarations, and gcse analysis.
3618 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3619 could be assigned through a pointer, so don't complain.
3620 * src/SDCCast.c (astErrors),
3622 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4257 * src/SDCCsymt.c (sclsFromPtr),
4259 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4260 support for standard C idiom of memory mapped variables; for
4261 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4262 to xdata int at 0x1234 tempvar = 1.
4263 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4264 provided by Akiya ISHIDA

4280 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4282 Fixed bug #621531 (const & volatile confusion in the type chain).
4283 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4284 refer to the const or volatile state of the pointer itself.

4349 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
4350 pcoderegs.h, ralloc.c, ralloc.h
4351 * main.c: added top header and GPL license notice

4375 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4376 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4377 fetching of the pointer
4378 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4379 copied from genNearPointerSet()
4380 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4381 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4382 If they pop r0/r1 they must be called in the opposite order than aopOp().
4383 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4384 (resp. --stack-auto), prepared for --xstack

4395 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4397 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4398 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4399 type for bits was changed. It resulted in bit variables becoming
4400 global, which is not permitted in PIC 14 assembly output.
4402 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4404 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4417 A few small changes that speed up the peephole optimizer.
4421 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4423 Try to make the peephole optimizer smarter by maintaining
4424 an association between the assembly source code and the
4425 iCodes that originated them. Put this information to use
4426 with a new peephole rule condition "notVolatile" so that
4427 the rules can be aggressive yet still safe.
4432 * src/mcs51/peeph.def
4434 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4438 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4439 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4440 if the left or right operand symbols have the accuse flag set.
4442 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4444 Changed the type of the result of the ! (NOT) operator to char;
4445 previously it returned the same type as the source. This allows
4446 us to eliminate all the genFloatNot functions (all of its target
4447 implementations were very buggy) since !float can use the same
4450 * src/SDCCicode.c (ast2iCode): ! returns char

4459 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4460 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4461 during interrupts. Ensure WSAVE is located at a shared bank address.
4462 2. Fixed page selection in some places
4463 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4464 the registers name strings.
4465 4. Fixed "signed / unsigned compare" compiler warnings.
4466 5. The PIC port manages its own allocation of the general purpose
4467 registers, but makes no attempt to reuse them. As a result when
4468 compiling it soon runs out of general purpose registers. Some
4469 additional code was added to the files pcode.c and device.c to walk
4470 through the function call tree and rename the registers so that they
4480 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4481 genPlus() & genMinus() when the result is the same as left or right

4487 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4489 Made bitfield a distinct type from bit so that bitfields
4490 convert as per ANSI C and bits retain their traditional
4491 boolean style behaviour. Implemented bitfield support in
4499 * src/ds390/gen.c: bit v bitfield split
4500 * src/z80/gen.c: New support for bitfields
4501 * support/regression/tests/bitfields.c: reenabled z80,
4504 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4506 Rules 246.x, 247.x relate to bitfields, the others speed up
4507 access to xdata mapped I/O devices.
4509 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4511 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4513 Cleaned up genPackBits and genUnpackBits and added two helper
4514 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4515 for literal assignments in genPackBits (thanks to Frieder for
4521 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4523 Fixed bug #748310 (pointer to function type mishandled when the
4524 function name is omitted). Also fixed a SIGSEGV when a function
4525 attribute (reentrant, etc) is used on a non-function or on a
4526 function but misplaced before the parameter list.
4528 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4530 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4531 * support/Util/SDCCerr.h,
4532 * support/Util/SDCCerr.c: Added func attr misuse error msg

4553 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4555 Made the constant following the "interrupt" keyword optional. If
4556 omitted, the function will not automatically be given an entry
4557 in the interrupt vector table (similar to #pragma NOIV, but
4558 less syntacticly kludgy). The interrupt number is also now
4559 range checked. Also fixed a bug in the high order bit example

4573 * src/SDCCicode.c (operandOperation): rewritten some ops
4574 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4575 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4577 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4578 be re-activated by defining REDUCE_LITERALS)
4579 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4580 unsigned, but are signed by default
4581 * src/SDCCval.c (constVal): rearranged
4582 * src/SDCCval.c (valMod): preliminary fix
4583 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4625 constants are unsigned; added recognition of "u" flag for unsigned
4626 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4627 * src/SDCCval.c (valDiv, valMod): fixed signdness
4628 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4629 signedness of modulo, left and right shift

5089 added if/endif conditional macros to remove options help
5090 messages from optionsTable when a port is not configured, added
5091 support for the PIc16 port in the ports table, when executing
5092 the compiler with no port specified on command line, a default
5093 port is selected with the new macro DEFAULT_PORT which is
5094 defined in port.h, in setDefaultOptions() linkOptions is removed
5095 from initialization assignment, since now it is a set,
5096 parseCmdLine uses setParseWithComma for linkOptions, in
5097 linkEdit() linkOptions are accessed with new function indexSet()
5098 which returns the i'th item of a set variable. See SDCCset.c, in
5099 linkEdit() when calling buildCmdLine(), added linkOptions as
5100 last argument. Now users can pass arguments to gplink via the
5101 -Wl option, main() uses pic16glue() to glue up pic16 programs

5115 gpasm complaining and test the linkage with gplink, _linkCmd and
5116 _asmCmd changed to be more gplink and gpasm friendly
5117 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5118 produced an error when parsed, peep rule 12 is added to utilize
5119 movff, but it is commented out since the pCode does not support
5120 yet a command with 2 address arguments
5122 2003-05-18 <johan AT balder>
5124 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5151 2003-05-11 Borut Razem <borut.razem AT siol.net>
5153 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6139 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
6140 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6142 2003-01-07 <johan AT balder>
6144 * src/SDCCast.c (decorateType): fixed bug #600035
6146 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6147 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

6157 2003-01-06 <johan AT balder>
6159 * src/SDCCicode.c: fixed array add
6161 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6162 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6163 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6165 2003-01-04 <johan AT balder>
6167 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6169 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6170 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6172 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6173 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6174 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6176 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6177 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6179 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6180 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6182 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6183 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6185 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6187 * in \sdcc\as\mcs51\ changed these files in order to create an
6188 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6189 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6190 following files to include the previous two files: aslink.dsp,
6191 Makefile.aslink, Makefile.bcc, and Makefile.in.
6193 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6194 .adb instead of .cdb
6196 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6198 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6199 value from option --iram-size.
6201 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6203 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6206 2002-09-18 <wiml AT hhhh.org>
6208 * SDCClrange.h: exposed setFromRange() and setToRange()
6209 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6210 packRegsForAccUse() (bug 542397)
6211 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6212 multiple times and emitting the fetch operations more than once
6213 added aopGetUsesAcc() function to allow binary operators to
6214 fetch their operands in the correct order; made genMinus() emit
6215 compact code for X = LITERAL - Y
6217 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6218 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6219 sprintf() in line 1267.
6221 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6222 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6225 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6226 Changes to aslink (All the changes are marked with 'JCF'):
6228 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6231 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6232 area BSEG. Also moves, if possible, the DATA area down into the internal
6233 ram so more space is available.
6235 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6238 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6239 not bytes. Function summary() which creates a memory usage summary
6240 file with extension .mem. Reports of overlaping stack and small stack
6241 size. If the space for the stack is less than 16 bytes aslink trows a
6244 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6245 the 8051. Option 'y' for memory summary output file.
6247 Changes to sdcc (All the changes are marked with 'JCF'):
6249 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6251 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6252 overlaying area for it (uses RegBankUsed[4]).
6254 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6255 bank zero as used by default. By default aslink locates the stack
6256 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6257 the creation of the .mem file. Delegates the allocation of data area
6258 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6259 the begining of the stack area to aslink.
6261 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6262 glue() in SDCCglue.c creates an area for it.
6264 2002-09-03 Borut Razem <borut.razem AT siol.net>
6265 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6266 sdcc/src/pic/glue.c:
6267 introduced atexit() handler for teporay files removal in case of
6268 errors, assertions, ...
6270 2002-08-29 Borut Razem <borut.razem AT siol.net>
6271 * sdcc/support/cpp2/auto-host_vc_in.h:
6272 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6273 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6274 Maybe there is a similar problem with BORLANDC? It should be checked!
6276 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6277 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6278 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6279 was not executed, and the compiler (cl) launched a warning:
6280 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6282 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6283 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6285 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6286 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6288 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6289 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6290 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6291 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6292 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6293 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6294 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6295 - added Release configuration in VS projects
6296 - review of compiler an linker options
6297 - VC .exe files are generated in bin_vc directory, not to interfere
6298 with binaries generated from other projects (cygwin, mingw, bcc ...)
6300 * sdcc/src/yacc.dsp: added
6302 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6303 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6304 and insert the version number definitions from .version
6306 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6308 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6309 added - genarate auto-host.h using auto-host_vc_in.h as template
6312 removed from CVS, generated automatically
6314 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6315 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6317 2002-08-11 Borut Razem <borut.razem AT siol.net>
6318 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6320 2002-08-10 Borut Razem <borut.razem AT siol.net>
6321 * src/SDCCmain.c (main):
6322 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6323 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6324 The consequence was that some temporary files were not removed.
6327 unification of code in functions tempfilename() and tempfile():
6328 function tempnam() is defined in Visual Studio 6.0 and .NET
6330 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6332 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6333 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6334 - removed compiler command line option /WX: Treats all warnings as errors
6335 - update a list of source files, included into the project
6337 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6338 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6339 changed project type to Generic Project so that can be correcly converted to VS.NET project
6341 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6343 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6345 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6347 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6348 added return 0 statements after assert() to make compiler happy
6350 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6351 added newline in the def file to keep MSC compiler satisfied
6353 * sdcc/src/z80/gen.c:
6354 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6355 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6356 - solved MSC error in function aopDump()
6358 * sdcc_vc.h: define PREFIX as "\\sdcc"
6360 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6361 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

6364 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6365 - Rewrote the register banking algorithm.
6366 - Added pCode live-range analysis to registers (for now, only non-used and
6367 singly-used registers optimized away)
6369 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6371 * 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.

6396 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6398 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6400 2002-03-28 Johan Knol <johan AT balder>
6402 * src/SDCCval.c: fixed bug #532436
6404 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6406 Added "char *Processor" field to the port structure.
6409 Added -p option. Allows port dependent processor to be specified.
6412 Initialized the new field char *Processor field to NULL in all ports
6415 Compiler generated registers for interrupt context saving
6416 were not getting allocated.
6418 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6421 Fixed left shift. Will promote the left side of a left shift
6422 if a) left shifting more than size of operand or b) when assigned
6423 to something size > size of left side
6425 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6427 tons of changes. Register allocation has been
6428 rewritten. Added customization for the various PICs. Flow
6429 analysis is restructured. ...
6435 Added. device.c is a PIC port hack to accomodate variations
6438 2002-03-13 Michael Hope <michaelh AT vroom>
6440 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6442 2002-03-04 johanknol <johanknol AT manik>
6444 * /src/SDCCval.c: fixed
6446 const unsigned char arr[][2] = { { 0, 1 } };
6447 t18.c:1: error: Initializer element is not constant
6449 2002-03-04 bela <bela AT manik>
6451 * /device/include/mcs51reg.h:
6452 ds89c420 register definition update
6454 2002-03-03 <johan AT FRIJA>

6533 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6535 * sdcc/src/SDCCloop.c:
6536 Previous fix was not good. basic blocks that have "break" or "return" are
6537 not really partof a loop , but live ranges used in these blocks should
6538 be live thru the entire loop, so set partOfLoop but don't add them to
6541 2002-02-21 <johan AT FRIJA>
6543 * src/SDCCcse.c: fixed bug #514308
6545 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6548 Fixed BUG #519583. If a conditional block ended in a return/break
6549 statement inside a loop, it was not being considered part of the loop.
6551 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6553 2002-02-10 Karl Bongers <karl AT turbobit.com>
6556 Fixed up SDCDB debugger somewhat. Updated debugger/README
6557 with lots of comments and notes.
6559 * device/examples/test2.c:
6560 Fix bug, "red" variable not being initialized(compiler complained).
6562 * device/examples/Makefile, examples/test3.c:
6563 Add Makefile in device/examples folder, compiles test3.c
6564 for use as a multiple module SDCDB test case.
6566 * sim/ucsim/cmd.src/cmdset.cc:
6567 Took out debug printfs in ucsim "next" command.
6570 Karl and Johan start ucsim XA support. Most dissassembly working,
6571 about 75% emulation done(plenty of work remaining).
6573 * sim/ucsim/z80.src:
6574 Add Z80 support to ucsim, add test-ucz80 regression test,
6575 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6576 Notice z80 compiler fails on examples/test3.c/crc code.
6578 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
6580 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

6588 from a memory mapped port
6589 2) added __builtin_memcmp
6590 3) added __builtin_swapw swap bytes of a short
6592 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
6593 1) handle multiple send & receives from register bank1
6594 2) ralloc can now allocate DPTR1 to some liveRanges
6596 * src/SDCCsymt.c, src/SDCCsymt.h:
6597 changes to handle multiple sends & receives
6600 added some pointer arithmetic optimization
6603 added some pointer arithmetic optimizations but not stable yet so not
6604 called from anywhere (will get this working shortly)
6606 * src/SDCCopt.c: fixed for multiple sends & receives
6609 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
6610 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
6611 set preprocessor defines (depending on options)
6613 * src/SDCCicode.c, src/SDCCicode.h:
6614 changes made to handle multiple sends & receives
6617 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
