419 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
421 Enabled VPATH feature: changed nearly all Makefiles (149 files).
422 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
424 One basic decision: e.g. src/clean.mk includes further files. In order
425 to make this work there are two solutions:
426 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
427 run configure on them. This way they can use
428 'include $(srcdir)/port-clean.mk'
429 - always include clean.mk by the Makefile at the same level. To avoid
430 that `make clean` tries to include and build Makefile.dep the
431 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
432 implemented, because now even `make uninstall` doesn't create
433 Makefile.in. clean.mk could be eliminated by pasting it in
436 * debugger/mcs51/Makefile.in: build own objects from library sources
437 (SLIB, SDCC) in current directory
439 * configure, configure.in: renamed --disable-device-lib-build in
440 --disable-device-lib; added --enable-doc, the required tools are
441 searched by configure; added result message; the toolchain for the
442 belonging ports are now only built, if the port is enabled.
444 * support/regression/*: all output is written in directory gen, because
445 the fwk and ports directories don't livet in the build tree using vpath
447 * doc/sdccman.lyx: renamed --disable-device-lib-build to
448 --disable-device-lib, added --enable-doc, added section VPATH
450 * sim/ucsim/configure.in,
451 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
452 z80 are enabled by default
454 2006-04-24 Raphael Neider <rneider AT web.de>
456 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
457 to config word, "pic14_"-prefixed some extern functions
458 (pic14_emitConfigWord): emit __config directive(s) if assignment to
459 config word has been found
460 * src/pic/device.h: added prototypes
461 * src/pic/pcode.c: added "pic14_"-prefix where needed
462 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
464 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
466 (pic14emitRegularMap): ignore config words,
467 (pic14createInterruptVect): moved generating __config directives away
468 (picglue): have __config directives emitted
470 2006-04-24 Borut Razem <borut.razem AT siol.net>
472 * doc/Makefile: sync with nightly build makefile
474 2006-04-24 Raphael Neider <rneider AT web.de>
476 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
477 registers that have not been assigned proper liveranges,
478 fixes #1469504 and #1474602,

744 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
747 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
749 * src/.version: increased version number to 2.5.5
750 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
751 linking is done manually in pic16 port's _linkEdit,
752 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
753 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

769 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
770 call to allocReg, not by manually allocating a new one,
771 (pic16_assignRegisters): now before going through the register
772 allocating functions mark all registers as free. This eliminates some
773 side effects resulting from peephole parser done earlier in the backbone
775 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

833 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
834 which dumps before the function entry point a data byte which represents
835 the number of the local variables used by the specified function, added
836 'xinst' for initial support for Extended Instruction Support,
837 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
838 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
839 port->fun_prefix anymore (may change later),
840 (genFunction, genEndFunction): do not store/restore local registers for
841 _main (this should take care the --main-return command line option in
843 (genOr): removed some legacy pic-port instructions,
844 * src/pic16/genarith.c (genAddLit): re-enabled old code because
845 performing operations with SFR's causes data to be written more than
846 once to each SFR. Perhaps SFRs should be handled in special cases...
847 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
849 * src/pic16/main.c (_process_pragma): stack bound checking did not take
850 into account for stack starting position,
851 (struct OPTIONS pic16_optionsTable): added command line argument
852 --extended or -y for Extended Instruction Support,
853 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
854 (deassignLRs): *** perhaps the most important change, old 'for' code
855 (commented out for reference), didn't account for some registers which
856 were left marked 'not free' after a pointer operation. The change
857 reduces register usage a lot in some cases

3133 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3134 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3135 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3136 always available in leading double underscore form. The C99 support is
3137 mostly missing, but it's a start.

3219 * device/lib/printf_large.c: removed inline assembly for portability and
3220 readability. Use printf_fast if speed or size are more important.
3221 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3222 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3224 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3226 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3227 prevent compiler warning
3229 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3231 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3232 moved to level 0 and declared as static. Also they are explicit
3233 placed in access bank. This was necessery because some times they
3234 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3235 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3236 optimizations. Currently only compare to unsigned char is implemented,
3237 * src/pic16/gen.c: added fReturnIdx array,
3238 * (struct resolvedIfx) is moved to gen.h and made public,
3239 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3240 * (aopForSym): added an optimization to directly store in stack of
3241 the operand of a SEND iCode,
3242 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3243 but as registers instead (AOP_REG) using the fReturnIdx array,
3244 * (pic16_freeAsmop): remove the freed register from the
3245 _G.sregsAlloc field,
3246 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3247 a compare of 'WREG',
3248 * (pic16_popGetTempRegCond): changed function prototype, now
3249 function takes also a bitVector argument v which holds the current
3250 set of registers that are allocated for stack access by aopForSym,
3251 registers allocated in aopForSym for accessing stack symbols are not
3252 any more part of the functions usedRegs field,
3253 * (genCall): some times aopOp is called for a stack variable to be
3254 send, aopForSym might perform the push, if this is true make sure
3255 that genCall doesn't push the variable twice by testing _G.resDirect,
3256 * (genFunction): changed testing for unspecified interrupt number
3257 from 256 to INTNO_UNSPEC,
3258 * modified selection scheme of frame pointer generation. Previously
3259 if function did use local registers a frame pointer was generated,
3260 now a frame pointer is generated only if function has arguments
3261 (that need PLUSW2 register access), or has stack arguments, or the
3262 compiler is not instructed to omit the frame pointer,
3263 * (genEndFunction): before restoring local registers that were saved
3264 in the function preamble, also restore the registers that *might*
3265 have been allocated for stack access,
3266 * (genRet): removed some old comments,
3267 * (genCmp, the active (RN's) version): added a call to the
3268 pic16_genCmp_special function to perform the compare with a more
3269 robust and optimized way,
3270 * (genInline): a feature has been added in inline code generation,
3271 which allows a wildcard variable substitution when writing inline
3272 assembly. Code is incomplete and experimental therefore undocumented,
3273 * (genCast): changed order of aopOp for result and right to allow
3274 aopForSym to directly load the result if possible,
3275 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3276 perform an optimized compare on some selected special occasions,
3277 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3278 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3279 generate an IVT any more,
3280 * src/pic16/main.c (pic16_optionsTable): added command line option
3282 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3283 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3285 * src/pic16/NOTES: Raphael Neider added in list of active developers
3286 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3287 jumptable_end to prevent bug #,
3288 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3289 inCond and outCond fields,
3290 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3291 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3292 turn off register spilling,
3293 * (packRegsForOneUse): synced with other ports' versions although it
3294 is not used currently,
3295 * (pic16_packRegisters): added an optimization while reading
3296 structure bitfields, some registers may be saved (malloc code is
3297 decreased by 80 bytes)
3299 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3301 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3302 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3303 this can be optimized more?
3305 2005-03-10 Raphael Neider <rneider AT web.de>
3307 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3308 genNearPointerGet): (hopefully) fixed access to bitfields via
3309 pointers (p->bitN = x; and x = p->bitN; failed)

3355 to keep the correct label reference count when adding/removing references
3356 to labels. A peephole file using this is appended to patch #1144962.

3941 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3943 Adding support for replacing ljmps with sjmps in jumptables
3944 generated for switch statements. For now you need to set the
3945 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3946 Now 4 algorithms for mcs51 jumptable generation are used:
3947 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3948 addresses loaded pc-relative for up to 112 cases and stack-pushing
3949 target addresses loaded with offset from dptr for up to 256 cases.

3976 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3977 to call when a stack overflow occurs,
3978 * (malloc.h): added CVS Id tag,
3979 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3981 * added libc directory. The current version of LibC contains string
3982 functions, ctype functions and macros and some functions of the
3983 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3984 be extensively tested in the future. Standard disclaimer here.
3985 Library is not automatically build yet. But one can build it by
3986 invoking 'make' inside the libc directory.
3987 * added ADC library under libio. Preliminary version yet.
3989 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3996 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3997 * (pic16_storeForReturn): optimized return of 0,
3998 * (genCmp): experimental code for new genCmp which uses PIC18's
3999 special compare&skip instructions. Initial tests fail some times
4000 with variables grater than 1 byte in size, so new code is disabled,
4001 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4003 * (genCast): began a fix to optimize the casting of a bit to another
4004 bit, now assigning a bitfield to another bitfield will fail, sorry,
4005 * src/pic16/main.c: disabled the use of lr-support feature,
4006 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4007 * added some function prototypes, added function _debugf prototype,

4009 bits with offset (case PO_GPR_BIT),
4010 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4012 * (isBankInstruction): modified to return 0 for no banking instruction,
4013 and 1 for banking instruction,
4014 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4015 caused stop processing pCodes after a inline assembly block,
4016 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4017 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4018 registers when it shouldn't,
4019 * src/pic16/ralloc.c (allocReg): add preliminary support for
4020 supporting a limited set of temporary registers,
4022 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4024 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4025 genDataPointerSet): ensure assignments always copy in MSB to LSB
4027 (loadRegFromAop): recognize CLRH optimization,
4028 (genFunction): optimize RECEIVE iCodes in reentrant functions
4030 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4032 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7027 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7029 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7030 loaded with the linker search paths (-L arguments) and the libraries
7031 to be linked with the current source (-l arguments). Changes
7032 currently will affect only the pic16 port.
7033 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7034 include path the port specific paths and port specific libraries,
7035 * gplink command now contains the $3 argument,
7036 * src/pic16/device.h,
7037 * src/pic16/device.c,: structure PIC_device is made public and
7038 renamed to PIC16_device, the same for variable Pics which is renamed
7039 to Pics16. Updated all references to them.
7040 * src/pic16/glue.c (pic16glue): corrected bug with code
7041 initialization which bypassed the variable initializations block.

7051 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7053 Documenting changes from previous commits.
7054 * configure.in (version 1.56),
7055 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7056 when generating output files to configure the pic16 library,
7057 but now I've commented it out, since gputils aren't installed in the
7058 SF compile farm, so library won't compile
7060 * device/lib/Makefile.in (version 1.56): initially I've added in
7061 target 'all' the prerequestive 'model-pic16' so it compiled the
7062 pic16 library, but now I've commented it out for the same reasons
7064 * added targets 'model-pic16' and 'objects-pic16' to compile the
7066 * added target 'port-specific-objects-pic16' to handle the
7067 generated libraries and copy them into the build/ directory
7068 * added target 'clean-intermediate-pic16' to clean intermediate
7069 files into pic16 directory
7070 * in target 'installdirs' added line to create directory pic16 in
7071 the installation path
7073 * device/include/Makefile.in (version 1.11): in target 'install'
7074 added lines to copy all header files to installation path,
7075 * in target 'installdirs' added line create directory for pic16
7076 headers in the installation path

7091 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7092 option so that it actually works. Made it specific to the z80, since
7093 the gbz80 doesn't have these kinds of I/O ports.
7095 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7097 * device/include/z180.h,

7110 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7112 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7113 changed interrupt vector table generation to only emit declared vectors.
7114 * device/include/Makefile.in: added missing backslash
7115 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7119 Mainly changes to support compilation of the device libraries
7120 * src/pic16/device.c: stack is allocated via symbol and not
7121 via literal number. The symbol is placed in the corresponding
7122 position of the data ram
7123 * (pic16_dump_section): relocatable and absolute uninitialized
7124 data are now emitted in sorted order to reduce section naming,
7125 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7126 weren't marked as being in the access bank,
7128 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7130 Added portion of GNU PIC Library under the directory
7131 device/include/pic16 and device/lib/pic16. These files
7132 contain the declarations of SFRs for the PIC18Fxx2 devices.
7133 The directory is initialized via configure from toplevel.
7135 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7137 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7138 the spilllocations to be compared correctly
7140 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7142 * src/SDCCast.c (decorateType): fixed bug introduced today
7144 2004-01-12 Borut Razem <borut.razem AT siol.net>
7146 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7149 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7151 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7152 in simpler and even better code
7154 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7156 * src/SDCCicode.c (operandOperation): fixed bug #874819

7160 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7162 * doc/sdccman.lyx: Moved and added some sections, small changes
7163 all over. Telling LaTeX to be less strict with word spacing
7164 to better keep the right margin. Changed some notes about
7165 maintainance of the ports in section 3.2.1 - is it OK like this?
7167 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7203 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7204 UPPER for immediate operands,
7205 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7207 * src/pic16/peeph.def: all peepholes with movff are commented out,
7208 because there is a problem in the pcode peep optimizer,
7209 * src/pic16/ralloc.c: the register allocator can now reuse local
7210 function symbols for another function. This saves register usage.
7211 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7213 Added file src/pic16/NOTES with information about program writing on
7214 the current port version.

7223 * src/SDCCmain.c : fixed #872250: -l command line defined library
7224 files are scanned before standard library files
7226 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7243 gen51Code): more efficient parameter receive for --model-large
7246 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7249 * src/z80/main.c: added missed needLinkerScript flags (more than
7250 one port structure defined in these file)
7251 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7267 needLinkerScript flag
7269 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7270 * src/pic/glue.c: added variable udata_section_name to
7271 override default uninitialized data segment definition for
7272 devices only with SHAREBANK memory (reported from Erik Epetrich)
7273 * (pic14emitOverlay): modified to emit a commented overlay segment
7274 directive when no overlay data exist
7275 * (picglue): modified to emit uninitialized data segment
7276 according to udata_section_name

7281 arguments via -W option
7282 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7283 object file from '.rel' to '.o' in port->linker structure,
7284 changed size of fptr from 2 to 3 in port structure
7286 2004-01-07 Borut Razem <borut.razem AT siol.net>
7288 * support/scripts/sdcc.nsi: update PATH
7289 * support/scripts/sdcc.ico: craeted
7291 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7294 * doc/Makefile: fix install
7296 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7298 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7300 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7302 include information about variables allocated to the overlay
7305 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7307 * as/mcs51/lkmain.c: Help about -Y option

7319 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7321 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7322 (default behaviour).
7324 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7326 A python script to validate compiler diagnostic messages. It can be
7327 used to verify that sdcc complains about bad c source code and
7328 gives a good location of the error.
7329 * support/valdiag/Makefile,
7330 * support/valdiag/valdiag.py,
7331 * support/valdiag/tests/*
7333 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7335 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7344 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7346 * src/common.h: added ifndef/define/endif macros
7347 around the header file.
7348 Bug reported from Jesus Calvino-Fraga
7350 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7352 * sdcc.spec: updated
7353 * device/include/Makefile.in: don't install CVS directories
7354 * device/lib/Makefile.in: added removal of CVS directories after install
7355 * doc/Makefile: fixed install, added local_icons
7356 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7357 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7358 * src/ds390/gen.c (genRightShift): fixed bug #870788
7359 * src/SDCCast.c (decorateType): fixed bug #870781
7361 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7363 PIC16 port related changes:
7364 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7365 added variable stackPos,
7367 * gen.c: genCall, assignResultValue: added support for
7368 pushing/retrieving function parameters to/from stack,
7369 genFunction,genEndFunction: setup stack frame for the
7371 genAddrOf: will be changed according to bug 863624
7373 * added files genutils.c and genutils.h which contain gen*
7374 debugged and optimised functions extracted from gen.c
7376 * glue.c: added variable 'externs' which holds extern symbols,
7377 pic16emitRegularMap: is modified to properly handle relocatable
7378 symbols under the new scheme,
7379 pic16createInterruptVect: is modified
7380 pic16printPublics: is modified to emit 'global' assembler directives,
7381 added pic16_printExterns to print extern symbols,
7382 pic16glue: initializes stack/frame pointer in the beginning of
7383 the assembly output. Temporary hack, will be corrected later,
7384 because gplink yet does not support stack and SDCC does not
7385 yet support a type of crt0.o object to create the final binary.
7387 * Removed many lines that contain 8051 legacy code.
7388 * The code is finally placed under a 'code' directive.
7389 * Added port specific options.
7391 * _process_pragma: simplified since now we do not need *special*
7392 include file to define SFR registers. But a separate header
7393 will be needed. This will be developed later.
7394 * _pic16_parseOptions: added, parses port specific options:
7395 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7396 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7397 --preplace-udata-with=
7399 * _pic16_setDefaultOptions: modified to initialize section names,
7400 but hack is temporarly out of order since it needs improvement.
7401 * _pic16_genAssemblerPreamble: configuration words are emitted by
7402 their address instead of their name. This part is incomplete and
7403 supports only the 18Fxx2 devices. Other devices will emit an error
7404 during assembly since they do not contain the same set of config
7406 * _pic16_genIVT: is modified,
7408 * pcode.c: added definitions for some hardware registers that are needed
7410 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7411 All PCI entries are updated. Now LFSR is supported.
7412 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7413 * added pic16_newpCodeOpLit2 to support instructions with
7414 two literal arguments
7415 * pic16_pCode2str: corrected code that emits assembler instructions
7416 with two literal operands and those that have an access bit modifier
7417 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7418 this fixes a bug which caused some labels to be lost, when an
7419 assembler directive was added, i.e. banksel,
7420 * pic16_FixRegisterBanking: improved logic that causes the insertion
7422 * InlineFunction: functions that are called once, are not any more
7423 inlined. This can be a port option in the future,
7425 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7427 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7428 hold the corresponding uninitialized symbols,
7429 * pic16_allocProcessorRegister: registers have explicit marked the
7431 * pic16_allocInternalRegister: registers are explicit marked as
7433 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7434 processing list, so bit registers were lost,
7437 * ralloc.h: added field 'accessBank' and original symbol operand
7438 in register definition,
7439 * removed the field isMapped from register definition,
7441 ** Several functions have been removed from various sources:
7442 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7443 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7444 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7445 pic16_assignRelocatableRegisters
7447 ** others have been introduced:
7448 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7449 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7451 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7453 * support/scripts/inc2h.pl: changed definition of BIT_AT
7454 to emit 'sbit at' instead of 'bit at'. This was a request.
7456 PIC16 port related preliminary changes:
7457 * gen.c: prefixed function popRegFromString with
7458 pic16_ and all references to it corrected
7459 * pcode.c: all pic16_pc_* hardware registers prefixed
7460 with underscore (_),
7461 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7462 * ralloc.c: newReg(): when register is REG_SFR then
7463 set address to rIdx,
7464 pic16_allocProcessorRegister(): marks register wasUsed=0
7465 pic16_writeUsedRegs(): added a call to assign processor
7466 registers via pic16_assignFixedRegisters
7468 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7470 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7471 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7472 variables in unused register banks. Also the SSEG is placed
7473 wherever there is enough space for it, and IDATA can be anywhere
7474 in internal RAM. For now compile using -Wl-Y[stack_size].
7475 The mem file is different for this option as well, since it

8474 iCode properly now. Use getSize instead of nRegs since a & b
8475 aren't part of the nRegs tally.
8477 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8479 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8480 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8481 before instructions that use the _STATUS register
8483 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8485 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8486 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8487 fetching of the pointer
8488 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8489 copied from genNearPointerSet()
8490 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8491 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8492 If they pop r0/r1 they must be called in the opposite order than aopOp().
8493 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8494 (resp. --stack-auto), prepared for --xstack

8505 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8507 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8508 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8509 type for bits was changed. It resulted in bit variables becoming
8510 global, which is not permitted in PIC 14 assembly output.
8512 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8514 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8527 A few small changes that speed up the peephole optimizer.
8531 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8533 Try to make the peephole optimizer smarter by maintaining
8534 an association between the assembly source code and the
8535 iCodes that originated them. Put this information to use
8536 with a new peephole rule condition "notVolatile" so that
8537 the rules can be aggressive yet still safe.
8542 * src/mcs51/peeph.def
8544 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8548 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8549 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8550 if the left or right operand symbols have the accuse flag set.
8552 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8554 Changed the type of the result of the ! (NOT) operator to char;
8555 previously it returned the same type as the source. This allows
8556 us to eliminate all the genFloatNot functions (all of its target
8557 implementations were very buggy) since !float can use the same
8560 * src/SDCCicode.c (ast2iCode): ! returns char

8569 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8570 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8571 during interrupts. Ensure WSAVE is located at a shared bank address.
8572 2. Fixed page selection in some places
8573 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8574 the registers name strings.
8575 4. Fixed "signed / unsigned compare" compiler warnings.
8576 5. The PIC port manages its own allocation of the general purpose
8577 registers, but makes no attempt to reuse them. As a result when
8578 compiling it soon runs out of general purpose registers. Some
8579 additional code was added to the files pcode.c and device.c to walk
8580 through the function call tree and rename the registers so that they
8590 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8597 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8599 Made bitfield a distinct type from bit so that bitfields
8600 convert as per ANSI C and bits retain their traditional
8601 boolean style behaviour. Implemented bitfield support in
8609 * src/ds390/gen.c: bit v bitfield split
8610 * src/z80/gen.c: New support for bitfields
8611 * support/regression/tests/bitfields.c: reenabled z80,
8614 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8616 Rules 246.x, 247.x relate to bitfields, the others speed up
8617 access to xdata mapped I/O devices.
8619 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8621 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8623 Cleaned up genPackBits and genUnpackBits and added two helper
8624 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8625 for literal assignments in genPackBits (thanks to Frieder for
8631 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8633 Fixed bug #748310 (pointer to function type mishandled when the
8634 function name is omitted). Also fixed a SIGSEGV when a function
8635 attribute (reentrant, etc) is used on a non-function or on a
8636 function but misplaced before the parameter list.
8638 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8640 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8663 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8665 Made the constant following the "interrupt" keyword optional. If
8666 omitted, the function will not automatically be given an entry
8667 in the interrupt vector table (similar to #pragma NOIV, but
8668 less syntacticly kludgy). The interrupt number is also now
8669 range checked. Also fixed a bug in the high order bit example

8685 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8687 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8688 be re-activated by defining REDUCE_LITERALS)
8689 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8690 unsigned, but are signed by default
8691 * src/SDCCval.c (constVal): rearranged
8692 * src/SDCCval.c (valMod): preliminary fix
8693 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9145 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9146 the regression tests I'm not brave enough to enable 245.b, 245.c
9147 * doc/sdccman.lyx: added latex preamble for hyperref package.
9148 Using pdflatex this will give you a hyperlinked pdf file with
9149 bookmarks. (prepend '%' before /usepackage if this breaks something)

9198 * src/SDCCmain.c: linkOptions is changed to set *,
9199 added if/endif conditional macros to remove options help
9200 messages from optionsTable when a port is not configured, added
9201 support for the PIc16 port in the ports table, when executing
9202 the compiler with no port specified on command line, a default
9203 port is selected with the new macro DEFAULT_PORT which is
9204 defined in port.h, in setDefaultOptions() linkOptions is removed
9205 from initialization assignment, since now it is a set,
9206 parseCmdLine uses setParseWithComma for linkOptions, in
9207 linkEdit() linkOptions are accessed with new function indexSet()
9208 which returns the i'th item of a set variable. See SDCCset.c, in
9209 linkEdit() when calling buildCmdLine(), added linkOptions as
9210 last argument. Now users can pass arguments to gplink via the
9211 -Wl option, main() uses pic16glue() to glue up pic16 programs

9223 * src/pic16/glue.c: commented out some error producing lines
9224 * src/pic16/main.c: __config directives are commented out to stop
9225 gpasm complaining and test the linkage with gplink, _linkCmd and
9226 _asmCmd changed to be more gplink and gpasm friendly
9227 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9228 produced an error when parsed, peep rule 12 is added to utilize
9229 movff, but it is commented out since the pCode does not support
9230 yet a command with 2 address arguments
9232 2003-05-18 <johan AT balder>
9234 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9235 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9259 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9261 2003-05-11 Borut Razem <borut.razem AT siol.net>
9263 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9264 the path of bin directory, so that PATH is the only env. variable, which has to be set
9265 in case of standard installation.
9266 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10298 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10299 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10300 following files to include the previous two files: aslink.dsp,
10301 Makefile.aslink, Makefile.bcc, and Makefile.in.
10303 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10304 .adb instead of .cdb
10306 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10308 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10309 value from option --iram-size.
10311 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10313 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10316 2002-09-18 <wiml AT hhhh.org>
10318 * SDCClrange.h: exposed setFromRange() and setToRange()
10319 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10320 packRegsForAccUse() (bug 542397)
10321 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10322 multiple times and emitting the fetch operations more than once
10323 added aopGetUsesAcc() function to allow binary operators to
10324 fetch their operands in the correct order; made genMinus() emit
10325 compact code for X = LITERAL - Y
10327 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10328 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

10331 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10332 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10335 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10336 Changes to aslink (All the changes are marked with 'JCF'):
10338 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10341 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10342 area BSEG. Also moves, if possible, the DATA area down into the internal
10343 ram so more space is available.
10345 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10348 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10349 not bytes. Function summary() which creates a memory usage summary
10350 file with extension .mem. Reports of overlaping stack and small stack
10351 size. If the space for the stack is less than 16 bytes aslink trows a
10354 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10355 the 8051. Option 'y' for memory summary output file.
10357 Changes to sdcc (All the changes are marked with 'JCF'):
10359 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10361 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10362 overlaying area for it (uses RegBankUsed[4]).
10364 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10365 bank zero as used by default. By default aslink locates the stack
10366 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10367 the creation of the .mem file. Delegates the allocation of data area
10368 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10369 the begining of the stack area to aslink.
10371 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10372 glue() in SDCCglue.c creates an area for it.
10374 2002-09-03 Borut Razem <borut.razem AT siol.net>
10375 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,

10380 2002-08-29 Borut Razem <borut.razem AT siol.net>
10381 * sdcc/support/cpp2/auto-host_vc_in.h:
10382 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10383 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10384 Maybe there is a similar problem with BORLANDC? It should be checked!
10386 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10387 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10388 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10389 was not executed, and the compiler (cl) launched a warning:
10390 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10392 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10393 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10396 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10398 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10399 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10400 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10401 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10402 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10403 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10404 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10405 - added Release configuration in VS projects
10406 - review of compiler an linker options
10407 - VC .exe files are generated in bin_vc directory, not to interfere
10408 with binaries generated from other projects (cygwin, mingw, bcc ...)
10410 * sdcc/src/yacc.dsp: added
10412 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10413 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10414 and insert the version number definitions from .version
10416 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10418 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10419 added - genarate auto-host.h using auto-host_vc_in.h as template
10422 removed from CVS, generated automatically
10424 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10425 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10427 2002-08-11 Borut Razem <borut.razem AT siol.net>
10428 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10430 2002-08-10 Borut Razem <borut.razem AT siol.net>
10431 * src/SDCCmain.c (main):
10432 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10433 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10434 The consequence was that some temporary files were not removed.
10437 unification of code in functions tempfilename() and tempfile():
10438 function tempnam() is defined in Visual Studio 6.0 and .NET
10440 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10442 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10443 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10444 - removed compiler command line option /WX: Treats all warnings as errors
10445 - update a list of source files, included into the project
10447 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10448 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10449 changed project type to Generic Project so that can be correcly converted to VS.NET project
10451 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10453 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10455 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10457 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10458 added return 0 statements after assert() to make compiler happy
10460 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10461 added newline in the def file to keep MSC compiler satisfied
10463 * sdcc/src/z80/gen.c:
10464 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10465 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10466 - solved MSC error in function aopDump()
10468 * sdcc_vc.h: define PREFIX as "\\sdcc"
10470 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10643 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10645 * sdcc/src/SDCCloop.c:
10646 Previous fix was not good. basic blocks that have "break" or "return" are
10647 not really partof a loop , but live ranges used in these blocks should
10648 be live thru the entire loop, so set partOfLoop but don't add them to
10651 2002-02-21 <johan AT FRIJA>
10653 * src/SDCCcse.c: fixed bug #514308
10655 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
