2926 loaded with the linker search paths (-L arguments) and the libraries
2927 to be linked with the current source (-l arguments). Changes
2928 currently will affect only the pic16 port.
2929 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2930 include path the port specific paths and port specific libraries,
2931 * gplink command now contains the $3 argument,
2932 * src/pic16/device.h,

2949 Documenting changes from previous commits.
2950 * configure.in (version 1.56),
2951 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2952 when generating output files to configure the pic16 library,
2953 but now I've commented it out, since gputils aren't installed in the
2954 SF compile farm, so library won't compile
2956 * device/lib/Makefile.in (version 1.56): initially I've added in
2957 target 'all' the prerequestive 'model-pic16' so it compiled the
2958 pic16 library, but now I've commented it out for the same reasons
2960 * added targets 'model-pic16' and 'objects-pic16' to compile the
2962 * added target 'port-specific-objects-pic16' to handle the
2963 generated libraries and copy them into the build/ directory
2964 * added target 'clean-intermediate-pic16' to clean intermediate
2965 files into pic16 directory
2966 * in target 'installdirs' added line to create directory pic16 in

3203 * as/mcs51/lkmain.c: Help about -Y option
3204 * as/mcs51/lkarea.c: Fixed gcc warnings
3206 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3208 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
3210 * support/valdiag/tests/overflow.c: added
3211 * src/SDCCast.c (decorateType),
3212 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
3213 LEFT_OP (left shift)
3215 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3217 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
3218 (default behaviour).
3220 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3222 A python script to validate compiler diagnostic messages. It can be
3223 used to verify that sdcc complains about bad c source code and
3224 gives a good location of the error.
3225 * support/valdiag/Makefile,
3226 * support/valdiag/valdiag.py,
3227 * support/valdiag/tests/*
3229 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3231 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
3232 * src/SDCCsymt.c (newEnumType),
3234 * support/Util/SDCCerr.c,
3235 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
3237 * support/regression/tests/enum.c: added test for enum values that
3238 require at least 2 bytes of storage.
3240 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3242 * src/common.h: added ifndef/define/endif macros
3243 around the header file.
3244 Bug reported from Jesus Calvino-Fraga
3246 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
3248 * sdcc.spec: updated
3249 * device/include/Makefile.in: don't install CVS directories
3250 * device/lib/Makefile.in: added removal of CVS directories after install
3251 * doc/Makefile: fixed install, added local_icons
3252 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
3253 * src/mcs51/gen.c (genRightShift): fixed bug #870788
3254 * src/ds390/gen.c (genRightShift): fixed bug #870788
3255 * src/SDCCast.c (decorateType): fixed bug #870781
3257 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
3259 PIC16 port related changes:
3260 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
3261 added variable stackPos,
3263 * gen.c: genCall, assignResultValue: added support for
3264 pushing/retrieving function parameters to/from stack,
3265 genFunction,genEndFunction: setup stack frame for the
3267 genAddrOf: will be changed according to bug 863624
3269 * added files genutils.c and genutils.h which contain gen*
3270 debugged and optimised functions extracted from gen.c
3272 * glue.c: added variable 'externs' which holds extern symbols,
3273 pic16emitRegularMap: is modified to properly handle relocatable
3274 symbols under the new scheme,
3275 pic16createInterruptVect: is modified
3276 pic16printPublics: is modified to emit 'global' assembler directives,
3277 added pic16_printExterns to print extern symbols,
3278 pic16glue: initializes stack/frame pointer in the beginning of
3279 the assembly output. Temporary hack, will be corrected later,
3280 because gplink yet does not support stack and SDCC does not
3281 yet support a type of crt0.o object to create the final binary.
3283 * Removed many lines that contain 8051 legacy code.
3284 * The code is finally placed under a 'code' directive.
3285 * Added port specific options.
3287 * _process_pragma: simplified since now we do not need *special*
3288 include file to define SFR registers. But a separate header
3289 will be needed. This will be developed later.
3290 * _pic16_parseOptions: added, parses port specific options:
3291 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
3292 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
3293 --preplace-udata-with=
3295 * _pic16_setDefaultOptions: modified to initialize section names,
3296 but hack is temporarly out of order since it needs improvement.
3297 * _pic16_genAssemblerPreamble: configuration words are emitted by
3298 their address instead of their name. This part is incomplete and
3299 supports only the 18Fxx2 devices. Other devices will emit an error
3300 during assembly since they do not contain the same set of config
3302 * _pic16_genIVT: is modified,
3304 * pcode.c: added definitions for some hardware registers that are needed
3306 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
3307 All PCI entries are updated. Now LFSR is supported.
3308 * Removed pic16_pciTRIS is mentioned by mdubuc in source
3309 * added pic16_newpCodeOpLit2 to support instructions with
3310 two literal arguments
3311 * pic16_pCode2str: corrected code that emits assembler instructions
3312 with two literal operands and those that have an access bit modifier
3313 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
3314 this fixes a bug which caused some labels to be lost, when an
3315 assembler directive was added, i.e. banksel,
3316 * pic16_FixRegisterBanking: improved logic that causes the insertion
3318 * InlineFunction: functions that are called once, are not any more
3319 inlined. This can be a port option in the future,
3321 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
3323 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
3324 hold the corresponding uninitialized symbols,
3325 * pic16_allocProcessorRegister: registers have explicit marked the
3327 * pic16_allocInternalRegister: registers are explicit marked as
3329 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
3330 processing list, so bit registers were lost,
3333 * ralloc.h: added field 'accessBank' and original symbol operand
3334 in register definition,
3335 * removed the field isMapped from register definition,
3337 ** Several functions have been removed from various sources:
3338 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
3339 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
3340 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
3341 pic16_assignRelocatableRegisters
3343 ** others have been introduced:
3344 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
3345 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
3347 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
3349 * support/scripts/inc2h.pl: changed definition of BIT_AT
3350 to emit 'sbit at' instead of 'bit at'. This was a request.
3352 PIC16 port related preliminary changes:
3353 * gen.c: prefixed function popRegFromString with
3354 pic16_ and all references to it corrected
3355 * pcode.c: all pic16_pc_* hardware registers prefixed
3356 with underscore (_),
3357 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
3358 * ralloc.c: newReg(): when register is REG_SFR then
3359 set address to rIdx,
3360 pic16_allocProcessorRegister(): marks register wasUsed=0
3361 pic16_writeUsedRegs(): added a call to assign processor
3362 registers via pic16_assignFixedRegisters
3364 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
3366 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
3367 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
3368 variables in unused register banks. Also the SSEG is placed
3369 wherever there is enough space for it, and IDATA can be anywhere
3370 in internal RAM. For now compile using -Wl-Y[stack_size].
3371 The mem file is different for this option as well, since it
3372 makes no sense of talking about DSEG lenght.
3374 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
3376 * src/SDCClrange.c: fixed bug 869095 that caused segfault
3377 in certain cases, e.g. when ROM assignment, patch provided
3378 from Albert den Haan.
3380 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

3523 * src/mcs51/peephole.def,
3524 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

3536 multiply defined with mismatching "at" address.
3538 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3540 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

3619 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3621 * src/SDCCast.c (decorateType): disabled a transformation I added in
3622 revision 1.188 (access to fields of a structure at an absolute address);
3623 it breaks with bitfields, extern declarations, and gcse analysis.
3624 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3625 could be assigned through a pointer, so don't complain.
3626 * src/SDCCast.c (astErrors),
3628 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4265 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
4266 support for standard C idiom of memory mapped variables; for
4267 example, *((xdata int*)0x1234) = 1 is now internally equivalent
4268 to xdata int at 0x1234 tempvar = 1.
4269 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
4270 provided by Akiya ISHIDA

4286 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4288 Fixed bug #621531 (const & volatile confusion in the type chain).
4289 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
4290 refer to the const or volatile state of the pointer itself.

4381 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
4382 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
4383 fetching of the pointer
4384 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
4385 copied from genNearPointerSet()
4386 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
4387 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
4388 If they pop r0/r1 they must be called in the opposite order than aopOp().
4389 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
4390 (resp. --stack-auto), prepared for --xstack

4401 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
4403 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4404 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
4405 type for bits was changed. It resulted in bit variables becoming
4406 global, which is not permitted in PIC 14 assembly output.
4408 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4410 * doc/sdccman.lyx: various additions and updates. Rearranged sections

4423 A few small changes that speed up the peephole optimizer.
4427 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4429 Try to make the peephole optimizer smarter by maintaining
4430 an association between the assembly source code and the
4431 iCodes that originated them. Put this information to use
4432 with a new peephole rule condition "notVolatile" so that
4433 the rules can be aggressive yet still safe.
4438 * src/mcs51/peeph.def
4440 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4444 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
4445 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
4446 if the left or right operand symbols have the accuse flag set.
4448 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4450 Changed the type of the result of the ! (NOT) operator to char;
4451 previously it returned the same type as the source. This allows
4452 us to eliminate all the genFloatNot functions (all of its target
4453 implementations were very buggy) since !float can use the same
4456 * src/SDCCicode.c (ast2iCode): ! returns char

4463 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
4465 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
4466 1. Interrupt would not compile properly. Ensure PCLATH register is saved
4467 during interrupts. Ensure WSAVE is located at a shared bank address.
4468 2. Fixed page selection in some places
4469 3. Fixed BTFSS/C to where necessary use registers directly and not simply
4470 the registers name strings.
4471 4. Fixed "signed / unsigned compare" compiler warnings.
4472 5. The PIC port manages its own allocation of the general purpose
4473 registers, but makes no attempt to reuse them. As a result when
4474 compiling it soon runs out of general purpose registers. Some
4475 additional code was added to the files pcode.c and device.c to walk
4476 through the function call tree and rename the registers so that they
4486 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
4487 genPlus() & genMinus() when the result is the same as left or right
4489 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4493 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4495 Made bitfield a distinct type from bit so that bitfields
4496 convert as per ANSI C and bits retain their traditional
4497 boolean style behaviour. Implemented bitfield support in
4505 * src/ds390/gen.c: bit v bitfield split
4506 * src/z80/gen.c: New support for bitfields
4507 * support/regression/tests/bitfields.c: reenabled z80,
4510 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4512 Rules 246.x, 247.x relate to bitfields, the others speed up
4513 access to xdata mapped I/O devices.
4515 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4517 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4519 Cleaned up genPackBits and genUnpackBits and added two helper
4520 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4521 for literal assignments in genPackBits (thanks to Frieder for
4527 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4529 Fixed bug #748310 (pointer to function type mishandled when the
4530 function name is omitted). Also fixed a SIGSEGV when a function
4531 attribute (reentrant, etc) is used on a non-function or on a
4532 function but misplaced before the parameter list.
4534 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4536 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4537 * support/Util/SDCCerr.h,
4538 * support/Util/SDCCerr.c: Added func attr misuse error msg

4559 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4561 Made the constant following the "interrupt" keyword optional. If
4562 omitted, the function will not automatically be given an entry
4563 in the interrupt vector table (similar to #pragma NOIV, but
4564 less syntacticly kludgy). The interrupt number is also now
4565 range checked. Also fixed a bug in the high order bit example

4576 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
4578 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
4579 * src/SDCCicode.c (operandOperation): rewritten some ops
4580 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4581 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4583 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4584 be re-activated by defining REDUCE_LITERALS)
4585 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4586 unsigned, but are signed by default
4587 * src/SDCCval.c (constVal): rearranged
4588 * src/SDCCval.c (valMod): preliminary fix
4589 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4631 constants are unsigned; added recognition of "u" flag for unsigned
4632 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4633 * src/SDCCval.c (valDiv, valMod): fixed signdness
4634 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4635 signedness of modulo, left and right shift

5095 added if/endif conditional macros to remove options help
5096 messages from optionsTable when a port is not configured, added
5097 support for the PIc16 port in the ports table, when executing
5098 the compiler with no port specified on command line, a default
5099 port is selected with the new macro DEFAULT_PORT which is
5100 defined in port.h, in setDefaultOptions() linkOptions is removed
5101 from initialization assignment, since now it is a set,
5102 parseCmdLine uses setParseWithComma for linkOptions, in
5103 linkEdit() linkOptions are accessed with new function indexSet()
5104 which returns the i'th item of a set variable. See SDCCset.c, in
5105 linkEdit() when calling buildCmdLine(), added linkOptions as
5106 last argument. Now users can pass arguments to gplink via the
5107 -Wl option, main() uses pic16glue() to glue up pic16 programs

5121 gpasm complaining and test the linkage with gplink, _linkCmd and
5122 _asmCmd changed to be more gplink and gpasm friendly
5123 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5124 produced an error when parsed, peep rule 12 is added to utilize
5125 movff, but it is commented out since the pCode does not support
5126 yet a command with 2 address arguments
5128 2003-05-18 <johan AT balder>
5130 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5157 2003-05-11 Borut Razem <borut.razem AT siol.net>
5159 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

6145 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
6146 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
6148 2003-01-07 <johan AT balder>
6150 * src/SDCCast.c (decorateType): fixed bug #600035
6152 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6153 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

6157 * src/pic/ralloc.c: outcommented unused variable to remove warnings
6159 2003-01-06 <karl AT turbobit.com>
6160 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
6163 2003-01-06 <johan AT balder>
6165 * src/SDCCicode.c: fixed array add
6167 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
6168 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
6169 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
6171 2003-01-04 <johan AT balder>
6173 * src/SDCCval.c (getNelements): fixed the initialized array of structures
6175 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6176 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
6178 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6179 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
6180 * support/regression/tests/bug-524697.c: fit mem usage into 8032
6182 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
6183 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
6185 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
6186 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
6188 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
6189 * src/mcs51/main.c: removed {bindir}{sep} from aslink
6191 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6193 * in \sdcc\as\mcs51\ changed these files in order to create an
6194 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
6195 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
6196 following files to include the previous two files: aslink.dsp,
6197 Makefile.aslink, Makefile.bcc, and Makefile.in.
6199 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
6200 .adb instead of .cdb
6202 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6204 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
6205 value from option --iram-size.
6207 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6209 * \sdcc\as\mcs51\lklist.c: added boundary check before using
6212 2002-09-18 <wiml AT hhhh.org>
6214 * SDCClrange.h: exposed setFromRange() and setToRange()
6215 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
6216 packRegsForAccUse() (bug 542397)
6217 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
6218 multiple times and emitting the fetch operations more than once
6219 added aopGetUsesAcc() function to allow binary operators to
6220 fetch their operands in the correct order; made genMinus() emit
6221 compact code for X = LITERAL - Y
6223 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6224 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
6225 sprintf() in line 1267.
6227 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6228 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6231 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6232 Changes to aslink (All the changes are marked with 'JCF'):
6234 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6237 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6238 area BSEG. Also moves, if possible, the DATA area down into the internal
6239 ram so more space is available.
6241 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
6244 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
6245 not bytes. Function summary() which creates a memory usage summary
6246 file with extension .mem. Reports of overlaping stack and small stack
6247 size. If the space for the stack is less than 16 bytes aslink trows a
6250 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
6251 the 8051. Option 'y' for memory summary output file.
6253 Changes to sdcc (All the changes are marked with 'JCF'):
6255 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
6257 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
6258 overlaying area for it (uses RegBankUsed[4]).
6260 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
6261 bank zero as used by default. By default aslink locates the stack
6262 (equivalent to --stack-after-data). Pass option 'y' to aslink for
6263 the creation of the .mem file. Delegates the allocation of data area
6264 to aslink (it is not longer 0x30 by default). If --stack-loc passes
6265 the begining of the stack area to aslink.
6267 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
6268 glue() in SDCCglue.c creates an area for it.
6270 2002-09-03 Borut Razem <borut.razem AT siol.net>
6271 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
6272 sdcc/src/pic/glue.c:
6273 introduced atexit() handler for teporay files removal in case of
6274 errors, assertions, ...
6276 2002-08-29 Borut Razem <borut.razem AT siol.net>
6277 * sdcc/support/cpp2/auto-host_vc_in.h:
6278 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
6279 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
6280 Maybe there is a similar problem with BORLANDC? It should be checked!
6282 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
6283 corrected improper use of assert: the assignment to clr variable was done inside the assert.
6284 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
6285 was not executed, and the compiler (cl) launched a warning:
6286 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
6288 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
6289 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
6291 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
6292 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
6294 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6295 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
6296 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
6297 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6298 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
6299 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
6300 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
6301 - added Release configuration in VS projects
6302 - review of compiler an linker options
6303 - VC .exe files are generated in bin_vc directory, not to interfere
6304 with binaries generated from other projects (cygwin, mingw, bcc ...)
6306 * sdcc/src/yacc.dsp: added
6308 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
6309 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
6310 and insert the version number definitions from .version
6312 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
6314 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
6315 added - genarate auto-host.h using auto-host_vc_in.h as template
6318 removed from CVS, generated automatically
6320 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
6321 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
6323 2002-08-11 Borut Razem <borut.razem AT siol.net>
6324 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
6326 2002-08-10 Borut Razem <borut.razem AT siol.net>
6327 * src/SDCCmain.c (main):
6328 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
6329 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
6330 The consequence was that some temporary files were not removed.
6333 unification of code in functions tempfilename() and tempfile():
6334 function tempnam() is defined in Visual Studio 6.0 and .NET
6336 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
6338 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
6339 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
6340 - removed compiler command line option /WX: Treats all warnings as errors
6341 - update a list of source files, included into the project
6343 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
6344 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
6345 changed project type to Generic Project so that can be correcly converted to VS.NET project
6347 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
6349 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
6351 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
6353 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
6354 added return 0 statements after assert() to make compiler happy
6356 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
6357 added newline in the def file to keep MSC compiler satisfied
6359 * sdcc/src/z80/gen.c:
6360 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
6361 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
6362 - solved MSC error in function aopDump()
6364 * sdcc_vc.h: define PREFIX as "\\sdcc"
6366 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
6367 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
6369 2002-06-22 Scott Dattalo <scott AT dattalo.com>
6370 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
6371 - Rewrote the register banking algorithm.
6372 - Added pCode live-range analysis to registers (for now, only non-used and
6373 singly-used registers optimized away)
6375 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
6377 * 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.

6402 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
6404 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
6406 2002-03-28 Johan Knol <johan AT balder>
6408 * src/SDCCval.c: fixed bug #532436
6410 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6412 Added "char *Processor" field to the port structure.
6415 Added -p option. Allows port dependent processor to be specified.
6418 Initialized the new field char *Processor field to NULL in all ports
6421 Compiler generated registers for interrupt context saving
6422 were not getting allocated.
6424 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
6427 Fixed left shift. Will promote the left side of a left shift
6428 if a) left shifting more than size of operand or b) when assigned
6429 to something size > size of left side
6431 2002-03-14 Scott Dattalo <scott AT dattalo.com>
6433 tons of changes. Register allocation has been
6434 rewritten. Added customization for the various PICs. Flow
6435 analysis is restructured. ...
6441 Added. device.c is a PIC port hack to accomodate variations
6444 2002-03-13 Michael Hope <michaelh AT vroom>
6446 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
6448 2002-03-04 johanknol <johanknol AT manik>
6450 * /src/SDCCval.c: fixed
6452 const unsigned char arr[][2] = { { 0, 1 } };
6453 t18.c:1: error: Initializer element is not constant
6455 2002-03-04 bela <bela AT manik>
6457 * /device/include/mcs51reg.h:
6458 ds89c420 register definition update
6460 2002-03-03 <johan AT FRIJA>

6539 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6541 * sdcc/src/SDCCloop.c:
6542 Previous fix was not good. basic blocks that have "break" or "return" are
6543 not really partof a loop , but live ranges used in these blocks should
6544 be live thru the entire loop, so set partOfLoop but don't add them to
6547 2002-02-21 <johan AT FRIJA>
6549 * src/SDCCcse.c: fixed bug #514308
6551 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6554 Fixed BUG #519583. If a conditional block ended in a return/break
6555 statement inside a loop, it was not being considered part of the loop.
6557 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6559 2002-02-10 Karl Bongers <karl AT turbobit.com>
6562 Fixed up SDCDB debugger somewhat. Updated debugger/README
6563 with lots of comments and notes.
6565 * device/examples/test2.c:
6566 Fix bug, "red" variable not being initialized(compiler complained).
6568 * device/examples/Makefile, examples/test3.c:
6569 Add Makefile in device/examples folder, compiles test3.c
6570 for use as a multiple module SDCDB test case.
6572 * sim/ucsim/cmd.src/cmdset.cc:
6573 Took out debug printfs in ucsim "next" command.
6576 Karl and Johan start ucsim XA support. Most dissassembly working,
6577 about 75% emulation done(plenty of work remaining).
6579 * sim/ucsim/z80.src:
6580 Add Z80 support to ucsim, add test-ucz80 regression test,
6581 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
6582 Notice z80 compiler fails on examples/test3.c/crc code.
6584 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
6586 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
6587 Added support for --parms-in-bank1
6589 * src/ds390/peeph.def:
6590 added a few more peephole optimzations
6593 1) added __builtin_inp & __builtin_outp used to read in data of given length
6594 from a memory mapped port
6595 2) added __builtin_memcmp
6596 3) added __builtin_swapw swap bytes of a short
6598 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
6599 1) handle multiple send & receives from register bank1
6600 2) ralloc can now allocate DPTR1 to some liveRanges
6602 * src/SDCCsymt.c, src/SDCCsymt.h:
6603 changes to handle multiple sends & receives
6606 added some pointer arithmetic optimization
6609 added some pointer arithmetic optimizations but not stable yet so not
6610 called from anywhere (will get this working shortly)
6612 * src/SDCCopt.c: fixed for multiple sends & receives
6615 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
6616 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
6617 set preprocessor defines (depending on options)
6619 * src/SDCCicode.c, src/SDCCicode.h:
6620 changes made to handle multiple sends & receives
6623 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
6625 * src/SDCCcse.c, src/SDCCcse.h:
6626 added function findbackward def (to be used in upcoming optimization)
