386 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
388 Enabled VPATH feature: changed nearly all Makefiles (149 files).
389 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
391 One basic decision: e.g. src/clean.mk includes further files. In order
392 to make this work there are two solutions:
393 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
394 run configure on them. This way they can use
395 'include $(srcdir)/port-clean.mk'
396 - always include clean.mk by the Makefile at the same level. To avoid
397 that `make clean` tries to include and build Makefile.dep the
398 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
399 implemented, because now even `make uninstall` doesn't create
400 Makefile.in. clean.mk could be eliminated by pasting it in
403 * debugger/mcs51/Makefile.in: build own objects from library sources
404 (SLIB, SDCC) in current directory
406 * configure, configure.in: renamed --disable-device-lib-build in
407 --disable-device-lib; added --enable-doc, the required tools are
408 searched by configure; added result message; the toolchain for the
409 belonging ports are now only built, if the port is enabled.
411 * support/regression/*: all output is written in directory gen, because
412 the fwk and ports directories don't livet in the build tree using vpath
414 * doc/sdccman.lyx: renamed --disable-device-lib-build to
415 --disable-device-lib, added --enable-doc, added section VPATH
417 * sim/ucsim/configure.in,
418 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
419 z80 are enabled by default
421 2006-04-24 Raphael Neider <rneider AT web.de>
423 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
424 to config word, "pic14_"-prefixed some extern functions
425 (pic14_emitConfigWord): emit __config directive(s) if assignment to
426 config word has been found
427 * src/pic/device.h: added prototypes
428 * src/pic/pcode.c: added "pic14_"-prefix where needed
429 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
431 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
433 (pic14emitRegularMap): ignore config words,
434 (pic14createInterruptVect): moved generating __config directives away

445 fixes #1469504 and #1474602,
446 (pCodeRegOptimizeRegUsage): fixed typo in comment
448 2006-04-24 Borut Razem <borut.razem AT siol.net>
450 * device/examples/main8051.c: deleted - it was removed from CVS
451 24.mar.2000 and after that modified 18.feb.2001, so it reappered
452 after the transition to Subversion
453 * src/SDCCalloc.h: deleted - it was removed from CVS
454 3.feb.2001 and after that modified 18.feb.2001, so it reappered

709 the left operand is shorter than the result (c* = lit-c* + int),
711 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
714 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
716 * src/.version: increased version number to 2.5.5
717 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
718 linking is done manually in pic16 port's _linkEdit,
719 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
720 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

803 'xinst' for initial support for Extended Instruction Support,
804 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
805 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
806 port->fun_prefix anymore (may change later),
807 (genFunction, genEndFunction): do not store/restore local registers for
808 _main (this should take care the --main-return command line option in
810 (genOr): removed some legacy pic-port instructions,
811 * src/pic16/genarith.c (genAddLit): re-enabled old code because
812 performing operations with SFR's causes data to be written more than
813 once to each SFR. Perhaps SFRs should be handled in special cases...
814 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
816 * src/pic16/main.c (_process_pragma): stack bound checking did not take
817 into account for stack starting position,
818 (struct OPTIONS pic16_optionsTable): added command line argument
819 --extended or -y for Extended Instruction Support,
820 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
821 (deassignLRs): *** perhaps the most important change, old 'for' code
822 (commented out for reference), didn't account for some registers which
823 were left marked 'not free' after a pointer operation. The change
824 reduces register usage a lot in some cases

3093 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3095 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3099 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3100 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3101 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3102 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3103 always available in leading double underscore form. The C99 support is
3104 mostly missing, but it's a start.
3105 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3106 reserved identifier "__data".
3108 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3152 immedDom() returning wrong block; probably fixes bug #1160833)
3154 2005-03-20 Borut Razem <borut.razem AT siol.net>
3156 * support/scripts/inc2h.pl: WIN32 port

3162 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3164 * device/include/stdint.h: added
3165 * device/lib/abs.c: added

3184 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3186 * device/lib/printf_large.c: removed inline assembly for portability and
3187 readability. Use printf_fast if speed or size are more important.
3188 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3189 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3191 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3193 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3194 prevent compiler warning
3196 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3198 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3199 moved to level 0 and declared as static. Also they are explicit
3200 placed in access bank. This was necessery because some times they
3201 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3202 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3203 optimizations. Currently only compare to unsigned char is implemented,
3204 * src/pic16/gen.c: added fReturnIdx array,
3205 * (struct resolvedIfx) is moved to gen.h and made public,
3206 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3207 * (aopForSym): added an optimization to directly store in stack of
3208 the operand of a SEND iCode,
3209 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3210 but as registers instead (AOP_REG) using the fReturnIdx array,
3211 * (pic16_freeAsmop): remove the freed register from the
3212 _G.sregsAlloc field,
3213 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3214 a compare of 'WREG',
3215 * (pic16_popGetTempRegCond): changed function prototype, now
3216 function takes also a bitVector argument v which holds the current
3217 set of registers that are allocated for stack access by aopForSym,
3218 registers allocated in aopForSym for accessing stack symbols are not
3219 any more part of the functions usedRegs field,
3220 * (genCall): some times aopOp is called for a stack variable to be
3221 send, aopForSym might perform the push, if this is true make sure
3222 that genCall doesn't push the variable twice by testing _G.resDirect,
3223 * (genFunction): changed testing for unspecified interrupt number
3224 from 256 to INTNO_UNSPEC,
3225 * modified selection scheme of frame pointer generation. Previously
3226 if function did use local registers a frame pointer was generated,
3227 now a frame pointer is generated only if function has arguments
3228 (that need PLUSW2 register access), or has stack arguments, or the
3229 compiler is not instructed to omit the frame pointer,
3230 * (genEndFunction): before restoring local registers that were saved
3231 in the function preamble, also restore the registers that *might*
3232 have been allocated for stack access,
3233 * (genRet): removed some old comments,
3234 * (genCmp, the active (RN's) version): added a call to the
3235 pic16_genCmp_special function to perform the compare with a more
3236 robust and optimized way,
3237 * (genInline): a feature has been added in inline code generation,
3238 which allows a wildcard variable substitution when writing inline
3239 assembly. Code is incomplete and experimental therefore undocumented,
3240 * (genCast): changed order of aopOp for result and right to allow
3241 aopForSym to directly load the result if possible,
3242 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3243 perform an optimized compare on some selected special occasions,
3244 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3245 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3246 generate an IVT any more,
3247 * src/pic16/main.c (pic16_optionsTable): added command line option
3249 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3250 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3252 * src/pic16/NOTES: Raphael Neider added in list of active developers
3253 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3254 jumptable_end to prevent bug #,
3255 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3256 inCond and outCond fields,
3257 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3258 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3259 turn off register spilling,
3260 * (packRegsForOneUse): synced with other ports' versions although it
3261 is not used currently,
3262 * (pic16_packRegisters): added an optimization while reading
3263 structure bitfields, some registers may be saved (malloc code is
3264 decreased by 80 bytes)
3266 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3268 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3269 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3270 this can be optimized more?
3272 2005-03-10 Raphael Neider <rneider AT web.de>
3274 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3275 genNearPointerGet): (hopefully) fixed access to bitfields via
3276 pointers (p->bitN = x; and x = p->bitN; failed)
3278 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3280 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3321 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3322 to keep the correct label reference count when adding/removing references
3323 to labels. A peephole file using this is appended to patch #1144962.

3455 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3456 (sizeof(sectNames) changed to sizeof(sectName))
3457 Both patches fix segfaults under MinGW.

3462 Safe_[mc]?alloc()'ed variables
3463 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3464 of (byte sized) temporaries (assign them to WREG for now)
3465 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3466 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3467 this might fix SIGSEGVs on MinGW...
3468 * src/SDCCopt.c (killDeadCode): restored original behaviour
3469 (volatile operands might get thrown away though)

3897 comparisons, and supports quoted literals
3898 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3900 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3908 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3910 Adding support for replacing ljmps with sjmps in jumptables
3911 generated for switch statements. For now you need to set the
3912 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3913 Now 4 algorithms for mcs51 jumptable generation are used:
3914 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3915 addresses loaded pc-relative for up to 112 cases and stack-pushing
3916 target addresses loaded with offset from dptr for up to 256 cases.
3918 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3919 * src/mcs51/main.c: adapted constants for switch table generation
3920 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3942 Large cummulative patch for pic16 port.
3943 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3944 to call when a stack overflow occurs,
3945 * (malloc.h): added CVS Id tag,
3946 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3948 * added libc directory. The current version of LibC contains string
3949 functions, ctype functions and macros and some functions of the
3950 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3951 be extensively tested in the future. Standard disclaimer here.
3952 Library is not automatically build yet. But one can build it by
3953 invoking 'make' inside the libc directory.
3954 * added ADC library under libio. Preliminary version yet.
3956 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3957 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3958 aopForRemat() now and not by pic16_aopOp(),

3963 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3964 * (pic16_storeForReturn): optimized return of 0,
3965 * (genCmp): experimental code for new genCmp which uses PIC18's
3966 special compare&skip instructions. Initial tests fail some times
3967 with variables grater than 1 byte in size, so new code is disabled,
3968 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3970 * (genCast): began a fix to optimize the casting of a bit to another
3971 bit, now assigning a bitfield to another bitfield will fail, sorry,
3972 * src/pic16/main.c: disabled the use of lr-support feature,
3973 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3974 * added some function prototypes, added function _debugf prototype,

3976 bits with offset (case PO_GPR_BIT),
3977 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3979 * (isBankInstruction): modified to return 0 for no banking instruction,
3980 and 1 for banking instruction,
3981 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3982 caused stop processing pCodes after a inline assembly block,
3983 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3984 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3985 registers when it shouldn't,
3986 * src/pic16/ralloc.c (allocReg): add preliminary support for
3987 supporting a limited set of temporary registers,
3989 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3991 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3992 genDataPointerSet): ensure assignments always copy in MSB to LSB
3994 (loadRegFromAop): recognize CLRH optimization,
3995 (genFunction): optimize RECEIVE iCodes in reentrant functions
3997 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3999 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4011 instead of sjmp to ret
4012 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4013 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4015 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6997 loaded with the linker search paths (-L arguments) and the libraries
6998 to be linked with the current source (-l arguments). Changes
6999 currently will affect only the pic16 port.
7000 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7001 include path the port specific paths and port specific libraries,
7002 * gplink command now contains the $3 argument,
7003 * src/pic16/device.h,
7004 * src/pic16/device.c,: structure PIC_device is made public and
7005 renamed to PIC16_device, the same for variable Pics which is renamed
7006 to Pics16. Updated all references to them.
7007 * src/pic16/glue.c (pic16glue): corrected bug with code
7008 initialization which bypassed the variable initializations block.
7010 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7011 COMPILE_FLAGS and added the --nostdinc option
7013 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7015 * device/include/mc68hc908jb8.h: Register defs for another member
7016 of the hc08 family. Contributed by Bjorn Bringert - thanks!

7020 Documenting changes from previous commits.
7021 * configure.in (version 1.56),
7022 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7023 when generating output files to configure the pic16 library,
7024 but now I've commented it out, since gputils aren't installed in the
7025 SF compile farm, so library won't compile
7027 * device/lib/Makefile.in (version 1.56): initially I've added in
7028 target 'all' the prerequestive 'model-pic16' so it compiled the
7029 pic16 library, but now I've commented it out for the same reasons
7031 * added targets 'model-pic16' and 'objects-pic16' to compile the
7033 * added target 'port-specific-objects-pic16' to handle the
7034 generated libraries and copy them into the build/ directory
7035 * added target 'clean-intermediate-pic16' to clean intermediate
7036 files into pic16 directory
7037 * in target 'installdirs' added line to create directory pic16 in
7038 the installation path
7040 * device/include/Makefile.in (version 1.11): in target 'install'
7041 added lines to copy all header files to installation path,
7042 * in target 'installdirs' added line create directory for pic16
7043 headers in the installation path

7058 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7059 option so that it actually works. Made it specific to the z80, since
7060 the gbz80 doesn't have these kinds of I/O ports.
7062 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7064 * device/include/z180.h,

7086 Mainly changes to support compilation of the device libraries
7087 * src/pic16/device.c: stack is allocated via symbol and not
7088 via literal number. The symbol is placed in the corresponding
7089 position of the data ram
7090 * (pic16_dump_section): relocatable and absolute uninitialized
7091 data are now emitted in sorted order to reduce section naming,
7092 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7093 weren't marked as being in the access bank,
7095 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7097 Added portion of GNU PIC Library under the directory
7098 device/include/pic16 and device/lib/pic16. These files
7099 contain the declarations of SFRs for the PIC18Fxx2 devices.
7100 The directory is initialized via configure from toplevel.
7102 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7104 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7129 * doc/sdccman.lyx: Moved and added some sections, small changes
7130 all over. Telling LaTeX to be less strict with word spacing
7131 to better keep the right margin. Changed some notes about
7132 maintainance of the ports in section 3.2.1 - is it OK like this?
7134 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7171 UPPER for immediate operands,
7172 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7174 * src/pic16/peeph.def: all peepholes with movff are commented out,
7175 because there is a problem in the pcode peep optimizer,
7176 * src/pic16/ralloc.c: the register allocator can now reuse local

7178 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7180 Added file src/pic16/NOTES with information about program writing on
7181 the current port version.

7213 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7216 * src/z80/main.c: added missed needLinkerScript flags (more than
7217 one port structure defined in these file)
7218 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7234 needLinkerScript flag
7236 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7237 * src/pic/glue.c: added variable udata_section_name to
7238 override default uninitialized data segment definition for

7240 * (pic14emitOverlay): modified to emit a commented overlay segment
7241 directive when no overlay data exist
7242 * (picglue): modified to emit uninitialized data segment
7243 according to udata_section_name

7253 2004-01-07 Borut Razem <borut.razem AT siol.net>
7255 * support/scripts/sdcc.nsi: update PATH
7256 * support/scripts/sdcc.ico: craeted

7269 include information about variables allocated to the overlay
7272 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7274 * as/mcs51/lkmain.c: Help about -Y option

7286 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7288 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7289 (default behaviour).
7291 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7293 A python script to validate compiler diagnostic messages. It can be
7294 used to verify that sdcc complains about bad c source code and
7295 gives a good location of the error.
7296 * support/valdiag/Makefile,
7297 * support/valdiag/valdiag.py,
7298 * support/valdiag/tests/*
7300 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7315 Bug reported from Jesus Calvino-Fraga
7317 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7319 * sdcc.spec: updated
7320 * device/include/Makefile.in: don't install CVS directories
7321 * device/lib/Makefile.in: added removal of CVS directories after install
7322 * doc/Makefile: fixed install, added local_icons
7323 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7324 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7325 * src/ds390/gen.c (genRightShift): fixed bug #870788
7326 * src/SDCCast.c (decorateType): fixed bug #870781
7328 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7330 PIC16 port related changes:
7331 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7332 added variable stackPos,
7334 * gen.c: genCall, assignResultValue: added support for
7335 pushing/retrieving function parameters to/from stack,
7336 genFunction,genEndFunction: setup stack frame for the
7338 genAddrOf: will be changed according to bug 863624
7340 * added files genutils.c and genutils.h which contain gen*
7341 debugged and optimised functions extracted from gen.c
7343 * glue.c: added variable 'externs' which holds extern symbols,
7344 pic16emitRegularMap: is modified to properly handle relocatable
7345 symbols under the new scheme,
7346 pic16createInterruptVect: is modified
7347 pic16printPublics: is modified to emit 'global' assembler directives,
7348 added pic16_printExterns to print extern symbols,
7349 pic16glue: initializes stack/frame pointer in the beginning of
7350 the assembly output. Temporary hack, will be corrected later,
7351 because gplink yet does not support stack and SDCC does not
7352 yet support a type of crt0.o object to create the final binary.
7354 * Removed many lines that contain 8051 legacy code.
7355 * The code is finally placed under a 'code' directive.
7356 * Added port specific options.
7358 * _process_pragma: simplified since now we do not need *special*
7359 include file to define SFR registers. But a separate header
7360 will be needed. This will be developed later.
7361 * _pic16_parseOptions: added, parses port specific options:
7362 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7363 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7364 --preplace-udata-with=
7366 * _pic16_setDefaultOptions: modified to initialize section names,
7367 but hack is temporarly out of order since it needs improvement.
7368 * _pic16_genAssemblerPreamble: configuration words are emitted by
7369 their address instead of their name. This part is incomplete and
7370 supports only the 18Fxx2 devices. Other devices will emit an error
7371 during assembly since they do not contain the same set of config
7373 * _pic16_genIVT: is modified,
7375 * pcode.c: added definitions for some hardware registers that are needed
7377 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7378 All PCI entries are updated. Now LFSR is supported.
7379 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7380 * added pic16_newpCodeOpLit2 to support instructions with
7381 two literal arguments
7382 * pic16_pCode2str: corrected code that emits assembler instructions
7383 with two literal operands and those that have an access bit modifier
7384 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7385 this fixes a bug which caused some labels to be lost, when an
7386 assembler directive was added, i.e. banksel,
7387 * pic16_FixRegisterBanking: improved logic that causes the insertion
7389 * InlineFunction: functions that are called once, are not any more
7390 inlined. This can be a port option in the future,
7392 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7394 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7395 hold the corresponding uninitialized symbols,
7396 * pic16_allocProcessorRegister: registers have explicit marked the
7398 * pic16_allocInternalRegister: registers are explicit marked as
7400 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7401 processing list, so bit registers were lost,
7404 * ralloc.h: added field 'accessBank' and original symbol operand
7405 in register definition,
7406 * removed the field isMapped from register definition,
7408 ** Several functions have been removed from various sources:
7409 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7410 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7411 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7412 pic16_assignRelocatableRegisters
7414 ** others have been introduced:
7415 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7416 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7418 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7420 * support/scripts/inc2h.pl: changed definition of BIT_AT
7421 to emit 'sbit at' instead of 'bit at'. This was a request.
7423 PIC16 port related preliminary changes:
7424 * gen.c: prefixed function popRegFromString with
7425 pic16_ and all references to it corrected
7426 * pcode.c: all pic16_pc_* hardware registers prefixed
7427 with underscore (_),
7428 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7429 * ralloc.c: newReg(): when register is REG_SFR then
7430 set address to rIdx,
7431 pic16_allocProcessorRegister(): marks register wasUsed=0
7432 pic16_writeUsedRegs(): added a call to assign processor
7433 registers via pic16_assignFixedRegisters
7435 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7437 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7438 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7439 variables in unused register banks. Also the SSEG is placed
7440 wherever there is enough space for it, and IDATA can be anywhere
7441 in internal RAM. For now compile using -Wl-Y[stack_size].
7442 The mem file is different for this option as well, since it
7443 makes no sense of talking about DSEG lenght.
7445 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7447 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7448 in certain cases, e.g. when ROM assignment, patch provided
7449 from Albert den Haan.
7451 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8494 A few small changes that speed up the peephole optimizer.
8498 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8500 Try to make the peephole optimizer smarter by maintaining
8501 an association between the assembly source code and the
8502 iCodes that originated them. Put this information to use
8503 with a new peephole rule condition "notVolatile" so that
8504 the rules can be aggressive yet still safe.
8509 * src/mcs51/peeph.def
8511 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8515 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8516 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8517 if the left or right operand symbols have the accuse flag set.
8519 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8521 Changed the type of the result of the ! (NOT) operator to char;
8522 previously it returned the same type as the source. This allows
8523 us to eliminate all the genFloatNot functions (all of its target
8524 implementations were very buggy) since !float can use the same
8527 * src/SDCCicode.c (ast2iCode): ! returns char

8536 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8537 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8538 during interrupts. Ensure WSAVE is located at a shared bank address.
8539 2. Fixed page selection in some places
8540 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8541 the registers name strings.
8542 4. Fixed "signed / unsigned compare" compiler warnings.
8543 5. The PIC port manages its own allocation of the general purpose
8544 registers, but makes no attempt to reuse them. As a result when
8545 compiling it soon runs out of general purpose registers. Some
8546 additional code was added to the files pcode.c and device.c to walk
8547 through the function call tree and rename the registers so that they
8557 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8558 genPlus() & genMinus() when the result is the same as left or right

8564 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8566 Made bitfield a distinct type from bit so that bitfields
8567 convert as per ANSI C and bits retain their traditional
8568 boolean style behaviour. Implemented bitfield support in
8576 * src/ds390/gen.c: bit v bitfield split
8577 * src/z80/gen.c: New support for bitfields
8578 * support/regression/tests/bitfields.c: reenabled z80,
8581 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8583 Rules 246.x, 247.x relate to bitfields, the others speed up
8584 access to xdata mapped I/O devices.
8586 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8588 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8590 Cleaned up genPackBits and genUnpackBits and added two helper
8591 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8592 for literal assignments in genPackBits (thanks to Frieder for
8598 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8600 Fixed bug #748310 (pointer to function type mishandled when the
8601 function name is omitted). Also fixed a SIGSEGV when a function
8602 attribute (reentrant, etc) is used on a non-function or on a
8603 function but misplaced before the parameter list.
8605 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8607 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8630 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8632 Made the constant following the "interrupt" keyword optional. If
8633 omitted, the function will not automatically be given an entry
8634 in the interrupt vector table (similar to #pragma NOIV, but
8635 less syntacticly kludgy). The interrupt number is also now
8636 range checked. Also fixed a bug in the high order bit example

9077 condition and ignore commands.
9079 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9081 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9082 is in parts still quite out of date, I did changes as far as I felt makes sense
9083 for a non-native english speaker.
9084 Please feel free to add to the manual or to correct my changes.
9085 * doc/Makefile: undid touching the date of intermediate tex files.
9087 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9102 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9104 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9105 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9106 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9107 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9110 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9112 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9113 the regression tests I'm not brave enough to enable 245.b, 245.c
9114 * doc/sdccman.lyx: added latex preamble for hyperref package.
9115 Using pdflatex this will give you a hyperlinked pdf file with
9116 bookmarks. (prepend '%' before /usepackage if this breaks something)
9118 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9132 Applied patch from bug 737905 (renamed yylineo to mylineno):
9139 * src/pic16/pcode.c: Cleaned warnings
9140 * src/pic16/pcodeflow.c: Cleaned warnings
9141 * src/pic16/pcoderegs.c: Cleaned warnings

9152 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9154 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9156 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9157 it can be defined with CFLAGS when running configure
9158 * src/SDCCmain.c: fixed compiling + linking with object files
9160 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9162 * configure.in: configure for pic16 port,
9163 added --disable-pic16-port
9164 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9165 * src/SDCCmain.c: linkOptions is changed to set *,
9166 added if/endif conditional macros to remove options help
9167 messages from optionsTable when a port is not configured, added
9168 support for the PIc16 port in the ports table, when executing
9169 the compiler with no port specified on command line, a default
9170 port is selected with the new macro DEFAULT_PORT which is
9171 defined in port.h, in setDefaultOptions() linkOptions is removed
9172 from initialization assignment, since now it is a set,
9173 parseCmdLine uses setParseWithComma for linkOptions, in
9174 linkEdit() linkOptions are accessed with new function indexSet()
9175 which returns the i'th item of a set variable. See SDCCset.c, in
9176 linkEdit() when calling buildCmdLine(), added linkOptions as
9177 last argument. Now users can pass arguments to gplink via the
9178 -Wl option, main() uses pic16glue() to glue up pic16 programs
9179 * src/SDCCpeeph.c: various changes to support pic16
9180 * src/SDCCset.c: added function void *indexSet(set *, int) to
9181 return the i'th item of the set

9184 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9185 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9186 added macro DEFAULT_PORT
9187 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9188 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9190 * src/pic16/glue.c: commented out some error producing lines
9191 * src/pic16/main.c: __config directives are commented out to stop
9192 gpasm complaining and test the linkage with gplink, _linkCmd and
9193 _asmCmd changed to be more gplink and gpasm friendly
9194 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9195 produced an error when parsed, peep rule 12 is added to utilize
9196 movff, but it is commented out since the pCode does not support
9197 yet a command with 2 address arguments
9199 2003-05-18 <johan AT balder>
9201 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9202 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9221 on entry now. Add tbreak. Other enhancements and fixes for use
9224 2003-05-12 Borut Razem <borut.razem AT siol.net>
9226 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9228 2003-05-11 Borut Razem <borut.razem AT siol.net>
9230 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9231 the path of bin directory, so that PATH is the only env. variable, which has to be set
9232 in case of standard installation.
9233 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10262 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10264 * in \sdcc\as\mcs51\ changed these files in order to create an
10265 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10266 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10267 following files to include the previous two files: aslink.dsp,
10268 Makefile.aslink, Makefile.bcc, and Makefile.in.
10270 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10271 .adb instead of .cdb
10273 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10275 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10276 value from option --iram-size.
10278 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10280 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10283 2002-09-18 <wiml AT hhhh.org>
10285 * SDCClrange.h: exposed setFromRange() and setToRange()
10286 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10287 packRegsForAccUse() (bug 542397)
10288 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10289 multiple times and emitting the fetch operations more than once
10290 added aopGetUsesAcc() function to allow binary operators to
10291 fetch their operands in the correct order; made genMinus() emit
10292 compact code for X = LITERAL - Y
10294 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10295 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10296 sprintf() in line 1267.
10298 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10299 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10302 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10303 Changes to aslink (All the changes are marked with 'JCF'):
10305 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10308 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10309 area BSEG. Also moves, if possible, the DATA area down into the internal
10310 ram so more space is available.
10312 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10315 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10316 not bytes. Function summary() which creates a memory usage summary
10317 file with extension .mem. Reports of overlaping stack and small stack
10318 size. If the space for the stack is less than 16 bytes aslink trows a
10321 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10322 the 8051. Option 'y' for memory summary output file.
10324 Changes to sdcc (All the changes are marked with 'JCF'):
10326 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10328 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10329 overlaying area for it (uses RegBankUsed[4]).
10331 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10332 bank zero as used by default. By default aslink locates the stack
10333 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10334 the creation of the .mem file. Delegates the allocation of data area
10335 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10336 the begining of the stack area to aslink.
10338 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10339 glue() in SDCCglue.c creates an area for it.
10341 2002-09-03 Borut Razem <borut.razem AT siol.net>
10342 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10343 sdcc/src/pic/glue.c:
10344 introduced atexit() handler for teporay files removal in case of
10345 errors, assertions, ...
10347 2002-08-29 Borut Razem <borut.razem AT siol.net>
10348 * sdcc/support/cpp2/auto-host_vc_in.h:
10349 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10350 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10351 Maybe there is a similar problem with BORLANDC? It should be checked!
10353 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10354 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10355 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10356 was not executed, and the compiler (cl) launched a warning:
10357 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10359 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10360 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10362 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10371 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10372 - added Release configuration in VS projects
10373 - review of compiler an linker options
10374 - VC .exe files are generated in bin_vc directory, not to interfere
10375 with binaries generated from other projects (cygwin, mingw, bcc ...)
10377 * sdcc/src/yacc.dsp: added
10379 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10380 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10381 and insert the version number definitions from .version
10383 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10385 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10386 added - genarate auto-host.h using auto-host_vc_in.h as template
10389 removed from CVS, generated automatically
10391 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10392 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10394 2002-08-11 Borut Razem <borut.razem AT siol.net>
10395 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10397 2002-08-10 Borut Razem <borut.razem AT siol.net>
10398 * src/SDCCmain.c (main):
10399 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10400 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10401 The consequence was that some temporary files were not removed.
10404 unification of code in functions tempfilename() and tempfile():
10405 function tempnam() is defined in Visual Studio 6.0 and .NET
10407 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10409 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10410 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10411 - removed compiler command line option /WX: Treats all warnings as errors
10412 - update a list of source files, included into the project
10414 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10415 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10416 changed project type to Generic Project so that can be correcly converted to VS.NET project
10418 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10420 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10422 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10424 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10425 added return 0 statements after assert() to make compiler happy
10427 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10428 added newline in the def file to keep MSC compiler satisfied
10430 * sdcc/src/z80/gen.c:
10431 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10432 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10433 - solved MSC error in function aopDump()
10435 * sdcc_vc.h: define PREFIX as "\\sdcc"
10437 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10438 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10610 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10612 * sdcc/src/SDCCloop.c:
10613 Previous fix was not good. basic blocks that have "break" or "return" are
10614 not really partof a loop , but live ranges used in these blocks should
10615 be live thru the entire loop, so set partOfLoop but don't add them to
