333 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
335 Enabled VPATH feature: changed nearly all Makefiles (149 files).
336 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
338 One basic decision: e.g. src/clean.mk includes further files. In order
339 to make this work there are two solutions:
340 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
341 run configure on them. This way they can use
342 'include $(srcdir)/port-clean.mk'
343 - always include clean.mk by the Makefile at the same level. To avoid
344 that `make clean` tries to include and build Makefile.dep the
345 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
346 implemented, because now even `make uninstall` doesn't create
347 Makefile.in. clean.mk could be eliminated by pasting it in
350 * debugger/mcs51/Makefile.in: build own objects from library sources
351 (SLIB, SDCC) in current directory
353 * configure, configure.in: renamed --disable-device-lib-build in
354 --disable-device-lib; added --enable-doc, the required tools are
355 searched by configure; added result message; the toolchain for the
356 belonging ports are now only built, if the port is enabled.
358 * support/regression/*: all output is written in directory gen, because
359 the fwk and ports directories don't livet in the build tree using vpath
361 * doc/sdccman.lyx: renamed --disable-device-lib-build to
362 --disable-device-lib, added --enable-doc, added section VPATH
364 * sim/ucsim/configure.in,
365 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
366 z80 are enabled by default
368 2006-04-24 Raphael Neider <rneider AT web.de>
370 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
371 to config word, "pic14_"-prefixed some extern functions
372 (pic14_emitConfigWord): emit __config directive(s) if assignment to
373 config word has been found
374 * src/pic/device.h: added prototypes
375 * src/pic/pcode.c: added "pic14_"-prefix where needed
376 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
378 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
380 (pic14emitRegularMap): ignore config words,
381 (pic14createInterruptVect): moved generating __config directives away

397 * device/examples/main8051.c: deleted - it was removed from CVS

656 the left operand is shorter than the result (c* = lit-c* + int),
658 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
661 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
663 * src/.version: increased version number to 2.5.5
664 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
665 linking is done manually in pic16 port's _linkEdit,
666 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
667 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

669 allocate asmop as AOP_ACC,
670 (aopForRemat): added parameter 'bool result' in function declaration,

683 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
684 call to allocReg, not by manually allocating a new one,
685 (pic16_assignRegisters): now before going through the register
686 allocating functions mark all registers as free. This eliminates some
687 side effects resulting from peephole parser done earlier in the backbone

751 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
752 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
753 port->fun_prefix anymore (may change later),
754 (genFunction, genEndFunction): do not store/restore local registers for
755 _main (this should take care the --main-return command line option in
757 (genOr): removed some legacy pic-port instructions,
758 * src/pic16/genarith.c (genAddLit): re-enabled old code because
759 performing operations with SFR's causes data to be written more than
760 once to each SFR. Perhaps SFRs should be handled in special cases...
761 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
763 * src/pic16/main.c (_process_pragma): stack bound checking did not take
764 into account for stack starting position,
765 (struct OPTIONS pic16_optionsTable): added command line argument
766 --extended or -y for Extended Instruction Support,
767 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
768 (deassignLRs): *** perhaps the most important change, old 'for' code
769 (commented out for reference), didn't account for some registers which
770 were left marked 'not free' after a pointer operation. The change

3023 * device/lib/pic16/libsdcc/char/: various modifications to improve
3024 library performance,
3025 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
3026 information on the new functions of the c library and more...
3028 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3030 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
3032 2005-03-26 Raphael Neider <rneider AT web.de>
3034 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
3035 if condition == CARRY)
3036 * (genCmp): adapted to new genSkipc semantics
3037 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3038 on rIfx (genCmp was broken)
3040 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3042 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3043 * src/z80/main.c (_keywords[]),
3044 * src/SDCCglobal.h (struct options),
3046 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3047 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3048 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3049 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3050 always available in leading double underscore form. The C99 support is
3051 mostly missing, but it's a start.
3052 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3053 reserved identifier "__data".
3055 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3057 * src/mcs51/peeph.def: fixed bug 1170013
3059 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

3065 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3068 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3070 * src/port.h (struct PORT),

3098 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3099 immedDom() returning wrong block; probably fixes bug #1160833)
3101 2005-03-20 Borut Razem <borut.razem AT siol.net>
3103 * support/scripts/inc2h.pl: WIN32 port
3105 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3107 * device/lib/makefile.in: added abs.c and labs.c
3109 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3111 * device/include/stdint.h: added
3112 * device/lib/abs.c: added
3113 * device/lib/labs.c: added
3114 * device/include/stdlib.h: added abs() and labs() prototypes
3115 * device/lib/libsdcc.lib: added abs and labs
3116 * device/include/float.h,

3129 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3131 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3133 * device/lib/printf_large.c: removed inline assembly for portability and
3134 readability. Use printf_fast if speed or size are more important.
3135 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3136 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3138 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3140 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3141 prevent compiler warning
3143 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3145 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3146 moved to level 0 and declared as static. Also they are explicit
3147 placed in access bank. This was necessery because some times they
3148 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3149 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3150 optimizations. Currently only compare to unsigned char is implemented,
3151 * src/pic16/gen.c: added fReturnIdx array,
3152 * (struct resolvedIfx) is moved to gen.h and made public,
3153 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3154 * (aopForSym): added an optimization to directly store in stack of
3155 the operand of a SEND iCode,
3156 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3157 but as registers instead (AOP_REG) using the fReturnIdx array,
3158 * (pic16_freeAsmop): remove the freed register from the
3159 _G.sregsAlloc field,
3160 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3161 a compare of 'WREG',
3162 * (pic16_popGetTempRegCond): changed function prototype, now
3163 function takes also a bitVector argument v which holds the current
3164 set of registers that are allocated for stack access by aopForSym,
3165 registers allocated in aopForSym for accessing stack symbols are not
3166 any more part of the functions usedRegs field,
3167 * (genCall): some times aopOp is called for a stack variable to be
3168 send, aopForSym might perform the push, if this is true make sure
3169 that genCall doesn't push the variable twice by testing _G.resDirect,
3170 * (genFunction): changed testing for unspecified interrupt number
3171 from 256 to INTNO_UNSPEC,
3172 * modified selection scheme of frame pointer generation. Previously
3173 if function did use local registers a frame pointer was generated,
3174 now a frame pointer is generated only if function has arguments
3175 (that need PLUSW2 register access), or has stack arguments, or the
3176 compiler is not instructed to omit the frame pointer,
3177 * (genEndFunction): before restoring local registers that were saved
3178 in the function preamble, also restore the registers that *might*
3179 have been allocated for stack access,
3180 * (genRet): removed some old comments,
3181 * (genCmp, the active (RN's) version): added a call to the
3182 pic16_genCmp_special function to perform the compare with a more
3183 robust and optimized way,
3184 * (genInline): a feature has been added in inline code generation,
3185 which allows a wildcard variable substitution when writing inline
3186 assembly. Code is incomplete and experimental therefore undocumented,
3187 * (genCast): changed order of aopOp for result and right to allow
3188 aopForSym to directly load the result if possible,
3189 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3190 perform an optimized compare on some selected special occasions,
3191 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3192 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3193 generate an IVT any more,
3194 * src/pic16/main.c (pic16_optionsTable): added command line option
3196 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3197 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3199 * src/pic16/NOTES: Raphael Neider added in list of active developers
3200 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3201 jumptable_end to prevent bug #,
3202 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3203 inCond and outCond fields,
3204 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3205 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3206 turn off register spilling,
3207 * (packRegsForOneUse): synced with other ports' versions although it
3208 is not used currently,
3209 * (pic16_packRegisters): added an optimization while reading
3210 structure bitfields, some registers may be saved (malloc code is
3211 decreased by 80 bytes)
3213 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3215 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3216 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3217 this can be optimized more?
3219 2005-03-10 Raphael Neider <rneider AT web.de>
3221 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3222 genNearPointerGet): (hopefully) fixed access to bitfields via
3223 pointers (p->bitN = x; and x = p->bitN; failed)
3225 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3412 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3413 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3414 this might fix SIGSEGVs on MinGW...
3415 * src/SDCCopt.c (killDeadCode): restored original behaviour
3416 (volatile operands might get thrown away though)
3418 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3466 of the operands is volatile. Fixes #1020220
3468 2005-01-22 Daniel Winkler <post AT danielwinkler.de>

6941 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6943 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6944 loaded with the linker search paths (-L arguments) and the libraries
6945 to be linked with the current source (-l arguments). Changes
6946 currently will affect only the pic16 port.
6947 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6948 include path the port specific paths and port specific libraries,
6949 * gplink command now contains the $3 argument,
6950 * src/pic16/device.h,
6951 * src/pic16/device.c,: structure PIC_device is made public and
6952 renamed to PIC16_device, the same for variable Pics which is renamed

6967 Documenting changes from previous commits.
6968 * configure.in (version 1.56),
6969 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6970 when generating output files to configure the pic16 library,
6971 but now I've commented it out, since gputils aren't installed in the
6972 SF compile farm, so library won't compile
6974 * device/lib/Makefile.in (version 1.56): initially I've added in
6975 target 'all' the prerequestive 'model-pic16' so it compiled the
6976 pic16 library, but now I've commented it out for the same reasons
6978 * added targets 'model-pic16' and 'objects-pic16' to compile the
6980 * added target 'port-specific-objects-pic16' to handle the
6981 generated libraries and copy them into the build/ directory
6982 * added target 'clean-intermediate-pic16' to clean intermediate
6983 files into pic16 directory
6984 * in target 'installdirs' added line to create directory pic16 in
6985 the installation path
6987 * device/include/Makefile.in (version 1.11): in target 'install'
6988 added lines to copy all header files to installation path,
6989 * in target 'installdirs' added line create directory for pic16
6990 headers in the installation path
6992 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7003 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7005 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7006 option so that it actually works. Made it specific to the z80, since
7007 the gbz80 doesn't have these kinds of I/O ports.

7077 all over. Telling LaTeX to be less strict with word spacing
7078 to better keep the right margin. Changed some notes about
7079 maintainance of the ports in section 3.2.1 - is it OK like this?
7081 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7121 * src/pic16/peeph.def: all peepholes with movff are commented out,
7122 because there is a problem in the pcode peep optimizer,
7123 * src/pic16/ralloc.c: the register allocator can now reuse local

7216 include information about variables allocated to the overlay
7219 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7221 * as/mcs51/lkmain.c: Help about -Y option

7233 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7235 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7236 (default behaviour).
7238 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7240 A python script to validate compiler diagnostic messages. It can be
7241 used to verify that sdcc complains about bad c source code and
7242 gives a good location of the error.
7243 * support/valdiag/Makefile,
7244 * support/valdiag/valdiag.py,
7245 * support/valdiag/tests/*
7247 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7260 * src/common.h: added ifndef/define/endif macros
7261 around the header file.
7262 Bug reported from Jesus Calvino-Fraga
7264 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7266 * sdcc.spec: updated
7267 * device/include/Makefile.in: don't install CVS directories
7268 * device/lib/Makefile.in: added removal of CVS directories after install
7269 * doc/Makefile: fixed install, added local_icons
7270 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7271 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7272 * src/ds390/gen.c (genRightShift): fixed bug #870788
7273 * src/SDCCast.c (decorateType): fixed bug #870781
7275 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7277 PIC16 port related changes:
7278 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7279 added variable stackPos,
7281 * gen.c: genCall, assignResultValue: added support for
7282 pushing/retrieving function parameters to/from stack,
7283 genFunction,genEndFunction: setup stack frame for the
7285 genAddrOf: will be changed according to bug 863624
7287 * added files genutils.c and genutils.h which contain gen*
7288 debugged and optimised functions extracted from gen.c
7290 * glue.c: added variable 'externs' which holds extern symbols,
7291 pic16emitRegularMap: is modified to properly handle relocatable
7292 symbols under the new scheme,
7293 pic16createInterruptVect: is modified
7294 pic16printPublics: is modified to emit 'global' assembler directives,
7295 added pic16_printExterns to print extern symbols,
7296 pic16glue: initializes stack/frame pointer in the beginning of
7297 the assembly output. Temporary hack, will be corrected later,
7298 because gplink yet does not support stack and SDCC does not
7299 yet support a type of crt0.o object to create the final binary.
7301 * Removed many lines that contain 8051 legacy code.
7302 * The code is finally placed under a 'code' directive.
7303 * Added port specific options.
7305 * _process_pragma: simplified since now we do not need *special*
7306 include file to define SFR registers. But a separate header
7307 will be needed. This will be developed later.
7308 * _pic16_parseOptions: added, parses port specific options:
7309 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7310 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7311 --preplace-udata-with=
7313 * _pic16_setDefaultOptions: modified to initialize section names,
7314 but hack is temporarly out of order since it needs improvement.
7315 * _pic16_genAssemblerPreamble: configuration words are emitted by
7316 their address instead of their name. This part is incomplete and
7317 supports only the 18Fxx2 devices. Other devices will emit an error
7318 during assembly since they do not contain the same set of config
7320 * _pic16_genIVT: is modified,
7322 * pcode.c: added definitions for some hardware registers that are needed
7324 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7325 All PCI entries are updated. Now LFSR is supported.
7326 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7327 * added pic16_newpCodeOpLit2 to support instructions with
7328 two literal arguments
7329 * pic16_pCode2str: corrected code that emits assembler instructions
7330 with two literal operands and those that have an access bit modifier
7331 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7332 this fixes a bug which caused some labels to be lost, when an
7333 assembler directive was added, i.e. banksel,
7334 * pic16_FixRegisterBanking: improved logic that causes the insertion
7336 * InlineFunction: functions that are called once, are not any more
7337 inlined. This can be a port option in the future,
7339 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7341 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7342 hold the corresponding uninitialized symbols,
7343 * pic16_allocProcessorRegister: registers have explicit marked the
7345 * pic16_allocInternalRegister: registers are explicit marked as
7347 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7348 processing list, so bit registers were lost,
7351 * ralloc.h: added field 'accessBank' and original symbol operand
7352 in register definition,
7353 * removed the field isMapped from register definition,
7355 ** Several functions have been removed from various sources:
7356 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7357 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7358 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7359 pic16_assignRelocatableRegisters
7361 ** others have been introduced:
7362 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7363 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7365 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7367 * support/scripts/inc2h.pl: changed definition of BIT_AT
7368 to emit 'sbit at' instead of 'bit at'. This was a request.
7370 PIC16 port related preliminary changes:
7371 * gen.c: prefixed function popRegFromString with
7372 pic16_ and all references to it corrected
7373 * pcode.c: all pic16_pc_* hardware registers prefixed
7374 with underscore (_),
7375 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7376 * ralloc.c: newReg(): when register is REG_SFR then
7377 set address to rIdx,
7378 pic16_allocProcessorRegister(): marks register wasUsed=0
7379 pic16_writeUsedRegs(): added a call to assign processor
7380 registers via pic16_assignFixedRegisters
7382 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7384 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7385 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7386 variables in unused register banks. Also the SSEG is placed
7387 wherever there is enough space for it, and IDATA can be anywhere
7388 in internal RAM. For now compile using -Wl-Y[stack_size].
7389 The mem file is different for this option as well, since it
7390 makes no sense of talking about DSEG lenght.
7392 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7394 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7395 in certain cases, e.g. when ROM assignment, patch provided
7396 from Albert den Haan.
7398 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8421 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8422 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

8441 A few small changes that speed up the peephole optimizer.
8445 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8447 Try to make the peephole optimizer smarter by maintaining
8448 an association between the assembly source code and the
8449 iCodes that originated them. Put this information to use
8450 with a new peephole rule condition "notVolatile" so that
8451 the rules can be aggressive yet still safe.
8456 * src/mcs51/peeph.def
8458 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8462 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8463 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8464 if the left or right operand symbols have the accuse flag set.
8466 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8468 Changed the type of the result of the ! (NOT) operator to char;
8469 previously it returned the same type as the source. This allows
8470 us to eliminate all the genFloatNot functions (all of its target
8471 implementations were very buggy) since !float can use the same

8483 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8484 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8485 during interrupts. Ensure WSAVE is located at a shared bank address.
8486 2. Fixed page selection in some places
8487 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8488 the registers name strings.
8489 4. Fixed "signed / unsigned compare" compiler warnings.
8490 5. The PIC port manages its own allocation of the general purpose
8491 registers, but makes no attempt to reuse them. As a result when
8492 compiling it soon runs out of general purpose registers. Some
8493 additional code was added to the files pcode.c and device.c to walk
8494 through the function call tree and rename the registers so that they
8504 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8513 Made bitfield a distinct type from bit so that bitfields
8514 convert as per ANSI C and bits retain their traditional
8515 boolean style behaviour. Implemented bitfield support in
8523 * src/ds390/gen.c: bit v bitfield split
8524 * src/z80/gen.c: New support for bitfields

8531 access to xdata mapped I/O devices.
8533 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8535 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8537 Cleaned up genPackBits and genUnpackBits and added two helper
8538 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8539 for literal assignments in genPackBits (thanks to Frieder for
8545 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8547 Fixed bug #748310 (pointer to function type mishandled when the

8579 Made the constant following the "interrupt" keyword optional. If
8580 omitted, the function will not automatically be given an entry
8581 in the interrupt vector table (similar to #pragma NOIV, but
8582 less syntacticly kludgy). The interrupt number is also now
8583 range checked. Also fixed a bug in the high order bit example

9098 * doc/sdccman.lyx: fixed bug 739745
9099 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9101 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9103 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9104 it can be defined with CFLAGS when running configure
9105 * src/SDCCmain.c: fixed compiling + linking with object files
9107 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9109 * configure.in: configure for pic16 port,
9110 added --disable-pic16-port
9111 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9112 * src/SDCCmain.c: linkOptions is changed to set *,
9113 added if/endif conditional macros to remove options help
9114 messages from optionsTable when a port is not configured, added
9115 support for the PIc16 port in the ports table, when executing
9116 the compiler with no port specified on command line, a default
9117 port is selected with the new macro DEFAULT_PORT which is
9118 defined in port.h, in setDefaultOptions() linkOptions is removed
9119 from initialization assignment, since now it is a set,
9120 parseCmdLine uses setParseWithComma for linkOptions, in
9121 linkEdit() linkOptions are accessed with new function indexSet()
9122 which returns the i'th item of a set variable. See SDCCset.c, in
9123 linkEdit() when calling buildCmdLine(), added linkOptions as
9124 last argument. Now users can pass arguments to gplink via the
9125 -Wl option, main() uses pic16glue() to glue up pic16 programs
9126 * src/SDCCpeeph.c: various changes to support pic16
9127 * src/SDCCset.c: added function void *indexSet(set *, int) to

9137 * src/pic16/glue.c: commented out some error producing lines
9138 * src/pic16/main.c: __config directives are commented out to stop
9139 gpasm complaining and test the linkage with gplink, _linkCmd and
9140 _asmCmd changed to be more gplink and gpasm friendly
9141 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9142 produced an error when parsed, peep rule 12 is added to utilize
9143 movff, but it is commented out since the pCode does not support
9144 yet a command with 2 address arguments
9146 2003-05-18 <johan AT balder>
9148 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9175 2003-05-11 Borut Razem <borut.razem AT siol.net>
9177 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9178 the path of bin directory, so that PATH is the only env. variable, which has to be set
9179 in case of standard installation.

10207 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10209 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10211 * in \sdcc\as\mcs51\ changed these files in order to create an
10212 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10213 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10214 following files to include the previous two files: aslink.dsp,
10215 Makefile.aslink, Makefile.bcc, and Makefile.in.
10217 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10218 .adb instead of .cdb
10220 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10222 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10223 value from option --iram-size.
10225 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10227 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10230 2002-09-18 <wiml AT hhhh.org>
10232 * SDCClrange.h: exposed setFromRange() and setToRange()
10233 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10234 packRegsForAccUse() (bug 542397)
10235 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10236 multiple times and emitting the fetch operations more than once
10237 added aopGetUsesAcc() function to allow binary operators to
10238 fetch their operands in the correct order; made genMinus() emit
10239 compact code for X = LITERAL - Y
10241 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10242 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10243 sprintf() in line 1267.
10245 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10246 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10249 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10250 Changes to aslink (All the changes are marked with 'JCF'):
10252 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10255 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10256 area BSEG. Also moves, if possible, the DATA area down into the internal
10257 ram so more space is available.
10259 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10262 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10263 not bytes. Function summary() which creates a memory usage summary
10264 file with extension .mem. Reports of overlaping stack and small stack
10265 size. If the space for the stack is less than 16 bytes aslink trows a
10268 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10269 the 8051. Option 'y' for memory summary output file.
10271 Changes to sdcc (All the changes are marked with 'JCF'):
10273 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10275 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10276 overlaying area for it (uses RegBankUsed[4]).
10278 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10279 bank zero as used by default. By default aslink locates the stack
10280 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10281 the creation of the .mem file. Delegates the allocation of data area
10282 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10283 the begining of the stack area to aslink.
10285 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10286 glue() in SDCCglue.c creates an area for it.
10288 2002-09-03 Borut Razem <borut.razem AT siol.net>
10289 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10290 sdcc/src/pic/glue.c:
10291 introduced atexit() handler for teporay files removal in case of
10292 errors, assertions, ...
10294 2002-08-29 Borut Razem <borut.razem AT siol.net>
10295 * sdcc/support/cpp2/auto-host_vc_in.h:
10296 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10297 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10298 Maybe there is a similar problem with BORLANDC? It should be checked!
10300 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10301 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10302 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10303 was not executed, and the compiler (cl) launched a warning:
10304 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10306 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10307 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10309 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10310 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10312 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10313 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10314 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10315 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10316 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10317 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10318 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10319 - added Release configuration in VS projects
10320 - review of compiler an linker options
10321 - VC .exe files are generated in bin_vc directory, not to interfere
10322 with binaries generated from other projects (cygwin, mingw, bcc ...)
10324 * sdcc/src/yacc.dsp: added
10326 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10327 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10328 and insert the version number definitions from .version
10330 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10332 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10333 added - genarate auto-host.h using auto-host_vc_in.h as template
10336 removed from CVS, generated automatically
10338 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10339 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10341 2002-08-11 Borut Razem <borut.razem AT siol.net>
10342 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10344 2002-08-10 Borut Razem <borut.razem AT siol.net>
10345 * src/SDCCmain.c (main):
10346 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10347 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10348 The consequence was that some temporary files were not removed.
10351 unification of code in functions tempfilename() and tempfile():
10352 function tempnam() is defined in Visual Studio 6.0 and .NET
10354 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10356 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10357 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10358 - removed compiler command line option /WX: Treats all warnings as errors
10359 - update a list of source files, included into the project
10361 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10362 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10363 changed project type to Generic Project so that can be correcly converted to VS.NET project
10365 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10367 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10369 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10371 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10372 added return 0 statements after assert() to make compiler happy
10374 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10375 added newline in the def file to keep MSC compiler satisfied
10377 * sdcc/src/z80/gen.c:
10378 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10379 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
