392 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
394 Enabled VPATH feature: changed nearly all Makefiles (149 files).
395 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
397 One basic decision: e.g. src/clean.mk includes further files. In order
398 to make this work there are two solutions:
399 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
400 run configure on them. This way they can use
401 'include $(srcdir)/port-clean.mk'
402 - always include clean.mk by the Makefile at the same level. To avoid
403 that `make clean` tries to include and build Makefile.dep the
404 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
405 implemented, because now even `make uninstall` doesn't create
406 Makefile.in. clean.mk could be eliminated by pasting it in
409 * debugger/mcs51/Makefile.in: build own objects from library sources
410 (SLIB, SDCC) in current directory
412 * configure, configure.in: renamed --disable-device-lib-build in
413 --disable-device-lib; added --enable-doc, the required tools are
414 searched by configure; added result message; the toolchain for the
415 belonging ports are now only built, if the port is enabled.
417 * support/regression/*: all output is written in directory gen, because
418 the fwk and ports directories don't livet in the build tree using vpath
420 * doc/sdccman.lyx: renamed --disable-device-lib-build to
421 --disable-device-lib, added --enable-doc, added section VPATH
423 * sim/ucsim/configure.in,
424 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
425 z80 are enabled by default
427 2006-04-24 Raphael Neider <rneider AT web.de>
429 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
430 to config word, "pic14_"-prefixed some extern functions
431 (pic14_emitConfigWord): emit __config directive(s) if assignment to
432 config word has been found
433 * src/pic/device.h: added prototypes
434 * src/pic/pcode.c: added "pic14_"-prefix where needed
435 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
437 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
439 (pic14emitRegularMap): ignore config words,
440 (pic14createInterruptVect): moved generating __config directives away
441 (picglue): have __config directives emitted
443 2006-04-24 Borut Razem <borut.razem AT siol.net>
445 * doc/Makefile: sync with nightly build makefile

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

712 2006-03-16 Raphael Neider <rneider AT web.de>
714 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
715 the left operand is shorter than the result (c* = lit-c* + int),
717 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
720 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
722 * src/.version: increased version number to 2.5.5
723 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
724 linking is done manually in pic16 port's _linkEdit,
725 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
726 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

806 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
807 which dumps before the function entry point a data byte which represents
808 the number of the local variables used by the specified function, added
809 'xinst' for initial support for Extended Instruction Support,
810 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
811 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
812 port->fun_prefix anymore (may change later),
813 (genFunction, genEndFunction): do not store/restore local registers for
814 _main (this should take care the --main-return command line option in
816 (genOr): removed some legacy pic-port instructions,
817 * src/pic16/genarith.c (genAddLit): re-enabled old code because
818 performing operations with SFR's causes data to be written more than
819 once to each SFR. Perhaps SFRs should be handled in special cases...
820 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
822 * src/pic16/main.c (_process_pragma): stack bound checking did not take
823 into account for stack starting position,
824 (struct OPTIONS pic16_optionsTable): added command line argument
825 --extended or -y for Extended Instruction Support,
826 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
827 (deassignLRs): *** perhaps the most important change, old 'for' code
828 (commented out for reference), didn't account for some registers which
829 were left marked 'not free' after a pointer operation. The change
830 reduces register usage a lot in some cases

3099 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3101 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3105 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3106 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3107 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3108 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3109 always available in leading double underscore form. The C99 support is
3110 mostly missing, but it's a start.
3111 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3112 reserved identifier "__data".
3114 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3116 * src/mcs51/peeph.def: fixed bug 1170013

3158 immedDom() returning wrong block; probably fixes bug #1160833)
3160 2005-03-20 Borut Razem <borut.razem AT siol.net>
3162 * support/scripts/inc2h.pl: WIN32 port

3190 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3192 * device/lib/printf_large.c: removed inline assembly for portability and
3193 readability. Use printf_fast if speed or size are more important.
3194 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3195 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3197 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3199 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3200 prevent compiler warning
3202 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3204 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3205 moved to level 0 and declared as static. Also they are explicit
3206 placed in access bank. This was necessery because some times they
3207 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3208 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3209 optimizations. Currently only compare to unsigned char is implemented,
3210 * src/pic16/gen.c: added fReturnIdx array,
3211 * (struct resolvedIfx) is moved to gen.h and made public,
3212 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3213 * (aopForSym): added an optimization to directly store in stack of
3214 the operand of a SEND iCode,
3215 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3216 but as registers instead (AOP_REG) using the fReturnIdx array,
3217 * (pic16_freeAsmop): remove the freed register from the
3218 _G.sregsAlloc field,
3219 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3220 a compare of 'WREG',
3221 * (pic16_popGetTempRegCond): changed function prototype, now
3222 function takes also a bitVector argument v which holds the current
3223 set of registers that are allocated for stack access by aopForSym,
3224 registers allocated in aopForSym for accessing stack symbols are not
3225 any more part of the functions usedRegs field,
3226 * (genCall): some times aopOp is called for a stack variable to be
3227 send, aopForSym might perform the push, if this is true make sure
3228 that genCall doesn't push the variable twice by testing _G.resDirect,
3229 * (genFunction): changed testing for unspecified interrupt number
3230 from 256 to INTNO_UNSPEC,
3231 * modified selection scheme of frame pointer generation. Previously
3232 if function did use local registers a frame pointer was generated,
3233 now a frame pointer is generated only if function has arguments
3234 (that need PLUSW2 register access), or has stack arguments, or the
3235 compiler is not instructed to omit the frame pointer,
3236 * (genEndFunction): before restoring local registers that were saved
3237 in the function preamble, also restore the registers that *might*
3238 have been allocated for stack access,
3239 * (genRet): removed some old comments,
3240 * (genCmp, the active (RN's) version): added a call to the
3241 pic16_genCmp_special function to perform the compare with a more
3242 robust and optimized way,
3243 * (genInline): a feature has been added in inline code generation,
3244 which allows a wildcard variable substitution when writing inline
3245 assembly. Code is incomplete and experimental therefore undocumented,
3246 * (genCast): changed order of aopOp for result and right to allow
3247 aopForSym to directly load the result if possible,
3248 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3249 perform an optimized compare on some selected special occasions,
3250 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3251 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3252 generate an IVT any more,
3253 * src/pic16/main.c (pic16_optionsTable): added command line option
3255 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3256 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3258 * src/pic16/NOTES: Raphael Neider added in list of active developers
3259 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3260 jumptable_end to prevent bug #,
3261 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3262 inCond and outCond fields,
3263 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3264 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3265 turn off register spilling,
3266 * (packRegsForOneUse): synced with other ports' versions although it
3267 is not used currently,
3268 * (pic16_packRegisters): added an optimization while reading
3269 structure bitfields, some registers may be saved (malloc code is
3270 decreased by 80 bytes)
3272 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3274 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3275 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3276 this can be optimized more?
3278 2005-03-10 Raphael Neider <rneider AT web.de>
3280 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3281 genNearPointerGet): (hopefully) fixed access to bitfields via
3282 pointers (p->bitN = x; and x = p->bitN; failed)
3284 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3286 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3327 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3328 to keep the correct label reference count when adding/removing references
3329 to labels. A peephole file using this is appended to patch #1144962.

3461 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3462 (sizeof(sectNames) changed to sizeof(sectName))
3463 Both patches fix segfaults under MinGW.
3465 2005-01-23 Raphael Neider <rneider AT web.de>
3467 * src/pic16/{device.c,pcode.c}: s/free/Safe_free/g for
3468 Safe_[mc]?alloc()'ed variables
3469 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3470 of (byte sized) temporaries (assign them to WREG for now)
3471 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3472 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3473 this might fix SIGSEGVs on MinGW...

3901 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3902 architecture specific register naming into account, handles n-way
3903 comparisons, and supports quoted literals
3904 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3906 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3914 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3916 Adding support for replacing ljmps with sjmps in jumptables
3917 generated for switch statements. For now you need to set the
3918 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3919 Now 4 algorithms for mcs51 jumptable generation are used:
3920 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3921 addresses loaded pc-relative for up to 112 cases and stack-pushing
3922 target addresses loaded with offset from dptr for up to 256 cases.
3924 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3925 * src/mcs51/main.c: adapted constants for switch table generation
3926 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3948 Large cummulative patch for pic16 port.
3949 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3950 to call when a stack overflow occurs,
3951 * (malloc.h): added CVS Id tag,
3952 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3954 * added libc directory. The current version of LibC contains string
3955 functions, ctype functions and macros and some functions of the
3956 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3957 be extensively tested in the future. Standard disclaimer here.
3958 Library is not automatically build yet. But one can build it by
3959 invoking 'make' inside the libc directory.
3960 * added ADC library under libio. Preliminary version yet.
3962 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3969 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3970 * (pic16_storeForReturn): optimized return of 0,
3971 * (genCmp): experimental code for new genCmp which uses PIC18's
3972 special compare&skip instructions. Initial tests fail some times
3973 with variables grater than 1 byte in size, so new code is disabled,
3974 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3976 * (genCast): began a fix to optimize the casting of a bit to another
3977 bit, now assigning a bitfield to another bitfield will fail, sorry,
3978 * src/pic16/main.c: disabled the use of lr-support feature,
3979 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3980 * added some function prototypes, added function _debugf prototype,

3982 bits with offset (case PO_GPR_BIT),
3983 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3985 * (isBankInstruction): modified to return 0 for no banking instruction,
3986 and 1 for banking instruction,
3987 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3988 caused stop processing pCodes after a inline assembly block,
3989 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3990 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3991 registers when it shouldn't,
3992 * src/pic16/ralloc.c (allocReg): add preliminary support for
3993 supporting a limited set of temporary registers,
3995 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3997 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3998 genDataPointerSet): ensure assignments always copy in MSB to LSB
4000 (loadRegFromAop): recognize CLRH optimization,
4001 (genFunction): optimize RECEIVE iCodes in reentrant functions
4003 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4005 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4006 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4008 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4015 * device/lib/_gptrgetc.c (_gptrgetc),
4016 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4017 instead of sjmp to ret
4018 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4019 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4021 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7004 to be linked with the current source (-l arguments). Changes
7005 currently will affect only the pic16 port.
7006 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7007 include path the port specific paths and port specific libraries,
7008 * gplink command now contains the $3 argument,
7009 * src/pic16/device.h,
7010 * src/pic16/device.c,: structure PIC_device is made public and
7011 renamed to PIC16_device, the same for variable Pics which is renamed
7012 to Pics16. Updated all references to them.
7013 * src/pic16/glue.c (pic16glue): corrected bug with code
7014 initialization which bypassed the variable initializations block.
7016 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7017 COMPILE_FLAGS and added the --nostdinc option
7019 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7021 * device/include/mc68hc908jb8.h: Register defs for another member
7022 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7024 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7026 Documenting changes from previous commits.
7027 * configure.in (version 1.56),
7028 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7029 when generating output files to configure the pic16 library,
7030 but now I've commented it out, since gputils aren't installed in the
7031 SF compile farm, so library won't compile
7033 * device/lib/Makefile.in (version 1.56): initially I've added in
7034 target 'all' the prerequestive 'model-pic16' so it compiled the
7035 pic16 library, but now I've commented it out for the same reasons
7037 * added targets 'model-pic16' and 'objects-pic16' to compile the
7039 * added target 'port-specific-objects-pic16' to handle the
7040 generated libraries and copy them into the build/ directory
7041 * added target 'clean-intermediate-pic16' to clean intermediate
7042 files into pic16 directory
7043 * in target 'installdirs' added line to create directory pic16 in
7044 the installation path
7046 * device/include/Makefile.in (version 1.11): in target 'install'
7047 added lines to copy all header files to installation path,
7048 * in target 'installdirs' added line create directory for pic16
7049 headers in the installation path

7064 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7065 option so that it actually works. Made it specific to the z80, since
7066 the gbz80 doesn't have these kinds of I/O ports.
7068 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7070 * device/include/z180.h,

7092 Mainly changes to support compilation of the device libraries
7093 * src/pic16/device.c: stack is allocated via symbol and not
7094 via literal number. The symbol is placed in the corresponding
7095 position of the data ram
7096 * (pic16_dump_section): relocatable and absolute uninitialized
7097 data are now emitted in sorted order to reduce section naming,
7098 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7099 weren't marked as being in the access bank,
7101 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7103 Added portion of GNU PIC Library under the directory
7104 device/include/pic16 and device/lib/pic16. These files
7105 contain the declarations of SFRs for the PIC18Fxx2 devices.
7106 The directory is initialized via configure from toplevel.
7108 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7110 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7111 the spilllocations to be compared correctly
7113 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7115 * src/SDCCast.c (decorateType): fixed bug introduced today
7117 2004-01-12 Borut Razem <borut.razem AT siol.net>

7135 * doc/sdccman.lyx: Moved and added some sections, small changes
7136 all over. Telling LaTeX to be less strict with word spacing
7137 to better keep the right margin. Changed some notes about
7138 maintainance of the ports in section 3.2.1 - is it OK like this?
7140 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7177 UPPER for immediate operands,
7178 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7180 * src/pic16/peeph.def: all peepholes with movff are commented out,
7181 because there is a problem in the pcode peep optimizer,
7182 * src/pic16/ralloc.c: the register allocator can now reuse local
7183 function symbols for another function. This saves register usage.
7184 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7186 Added file src/pic16/NOTES with information about program writing on
7187 the current port version.

7196 * src/SDCCmain.c : fixed #872250: -l command line defined library
7197 files are scanned before standard library files
7199 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7219 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7222 * src/z80/main.c: added missed needLinkerScript flags (more than
7223 one port structure defined in these file)
7224 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7240 needLinkerScript flag
7242 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7243 * src/pic/glue.c: added variable udata_section_name to
7244 override default uninitialized data segment definition for
7245 devices only with SHAREBANK memory (reported from Erik Epetrich)
7246 * (pic14emitOverlay): modified to emit a commented overlay segment
7247 directive when no overlay data exist
7248 * (picglue): modified to emit uninitialized data segment
7249 according to udata_section_name

7254 arguments via -W option
7255 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7256 object file from '.rel' to '.o' in port->linker structure,
7257 changed size of fptr from 2 to 3 in port structure
7259 2004-01-07 Borut Razem <borut.razem AT siol.net>
7261 * support/scripts/sdcc.nsi: update PATH
7262 * support/scripts/sdcc.ico: craeted
7264 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7275 include information about variables allocated to the overlay
7278 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7280 * as/mcs51/lkmain.c: Help about -Y option

7292 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7294 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7295 (default behaviour).
7297 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7299 A python script to validate compiler diagnostic messages. It can be
7300 used to verify that sdcc complains about bad c source code and
7301 gives a good location of the error.
7302 * support/valdiag/Makefile,
7303 * support/valdiag/valdiag.py,
7304 * support/valdiag/tests/*
7306 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7319 * src/common.h: added ifndef/define/endif macros
7320 around the header file.
7321 Bug reported from Jesus Calvino-Fraga
7323 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7325 * sdcc.spec: updated
7326 * device/include/Makefile.in: don't install CVS directories
7327 * device/lib/Makefile.in: added removal of CVS directories after install
7328 * doc/Makefile: fixed install, added local_icons
7329 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7330 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7331 * src/ds390/gen.c (genRightShift): fixed bug #870788
7332 * src/SDCCast.c (decorateType): fixed bug #870781
7334 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7336 PIC16 port related changes:
7337 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7338 added variable stackPos,
7340 * gen.c: genCall, assignResultValue: added support for
7341 pushing/retrieving function parameters to/from stack,
7342 genFunction,genEndFunction: setup stack frame for the
7344 genAddrOf: will be changed according to bug 863624
7346 * added files genutils.c and genutils.h which contain gen*
7347 debugged and optimised functions extracted from gen.c
7349 * glue.c: added variable 'externs' which holds extern symbols,
7350 pic16emitRegularMap: is modified to properly handle relocatable
7351 symbols under the new scheme,
7352 pic16createInterruptVect: is modified
7353 pic16printPublics: is modified to emit 'global' assembler directives,
7354 added pic16_printExterns to print extern symbols,
7355 pic16glue: initializes stack/frame pointer in the beginning of
7356 the assembly output. Temporary hack, will be corrected later,
7357 because gplink yet does not support stack and SDCC does not
7358 yet support a type of crt0.o object to create the final binary.
7360 * Removed many lines that contain 8051 legacy code.
7361 * The code is finally placed under a 'code' directive.
7362 * Added port specific options.
7364 * _process_pragma: simplified since now we do not need *special*
7365 include file to define SFR registers. But a separate header
7366 will be needed. This will be developed later.
7367 * _pic16_parseOptions: added, parses port specific options:
7368 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7369 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7370 --preplace-udata-with=
7372 * _pic16_setDefaultOptions: modified to initialize section names,
7373 but hack is temporarly out of order since it needs improvement.
7374 * _pic16_genAssemblerPreamble: configuration words are emitted by
7375 their address instead of their name. This part is incomplete and
7376 supports only the 18Fxx2 devices. Other devices will emit an error
7377 during assembly since they do not contain the same set of config
7379 * _pic16_genIVT: is modified,
7381 * pcode.c: added definitions for some hardware registers that are needed
7383 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7384 All PCI entries are updated. Now LFSR is supported.
7385 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7386 * added pic16_newpCodeOpLit2 to support instructions with
7387 two literal arguments
7388 * pic16_pCode2str: corrected code that emits assembler instructions
7389 with two literal operands and those that have an access bit modifier
7390 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7391 this fixes a bug which caused some labels to be lost, when an
7392 assembler directive was added, i.e. banksel,
7393 * pic16_FixRegisterBanking: improved logic that causes the insertion
7395 * InlineFunction: functions that are called once, are not any more
7396 inlined. This can be a port option in the future,
7398 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7400 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7401 hold the corresponding uninitialized symbols,
7402 * pic16_allocProcessorRegister: registers have explicit marked the
7404 * pic16_allocInternalRegister: registers are explicit marked as
7406 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7407 processing list, so bit registers were lost,
7410 * ralloc.h: added field 'accessBank' and original symbol operand
7411 in register definition,
7412 * removed the field isMapped from register definition,
7414 ** Several functions have been removed from various sources:
7415 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7416 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7417 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7418 pic16_assignRelocatableRegisters
7420 ** others have been introduced:
7421 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7422 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7424 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7426 * support/scripts/inc2h.pl: changed definition of BIT_AT
7427 to emit 'sbit at' instead of 'bit at'. This was a request.
7429 PIC16 port related preliminary changes:
7430 * gen.c: prefixed function popRegFromString with
7431 pic16_ and all references to it corrected
7432 * pcode.c: all pic16_pc_* hardware registers prefixed
7433 with underscore (_),
7434 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7435 * ralloc.c: newReg(): when register is REG_SFR then
7436 set address to rIdx,
7437 pic16_allocProcessorRegister(): marks register wasUsed=0
7438 pic16_writeUsedRegs(): added a call to assign processor
7439 registers via pic16_assignFixedRegisters
7441 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7443 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7444 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7445 variables in unused register banks. Also the SSEG is placed
7446 wherever there is enough space for it, and IDATA can be anywhere
7447 in internal RAM. For now compile using -Wl-Y[stack_size].
7448 The mem file is different for this option as well, since it
7449 makes no sense of talking about DSEG lenght.
7451 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7453 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7454 in certain cases, e.g. when ROM assignment, patch provided
7455 from Albert den Haan.
7457 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8485 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8487 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8500 A few small changes that speed up the peephole optimizer.
8504 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8506 Try to make the peephole optimizer smarter by maintaining
8507 an association between the assembly source code and the
8508 iCodes that originated them. Put this information to use
8509 with a new peephole rule condition "notVolatile" so that
8510 the rules can be aggressive yet still safe.
8515 * src/mcs51/peeph.def
8517 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8521 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8522 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8523 if the left or right operand symbols have the accuse flag set.
8525 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8527 Changed the type of the result of the ! (NOT) operator to char;
8528 previously it returned the same type as the source. This allows
8529 us to eliminate all the genFloatNot functions (all of its target
8530 implementations were very buggy) since !float can use the same
8533 * src/SDCCicode.c (ast2iCode): ! returns char

8542 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8543 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8544 during interrupts. Ensure WSAVE is located at a shared bank address.
8545 2. Fixed page selection in some places
8546 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8547 the registers name strings.
8548 4. Fixed "signed / unsigned compare" compiler warnings.
8549 5. The PIC port manages its own allocation of the general purpose
8550 registers, but makes no attempt to reuse them. As a result when
8551 compiling it soon runs out of general purpose registers. Some
8552 additional code was added to the files pcode.c and device.c to walk
8553 through the function call tree and rename the registers so that they
8563 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8564 genPlus() & genMinus() when the result is the same as left or right

8570 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8572 Made bitfield a distinct type from bit so that bitfields
8573 convert as per ANSI C and bits retain their traditional
8574 boolean style behaviour. Implemented bitfield support in
8582 * src/ds390/gen.c: bit v bitfield split
8583 * src/z80/gen.c: New support for bitfields
8584 * support/regression/tests/bitfields.c: reenabled z80,
8587 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8589 Rules 246.x, 247.x relate to bitfields, the others speed up
8590 access to xdata mapped I/O devices.
8592 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8594 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8596 Cleaned up genPackBits and genUnpackBits and added two helper
8597 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8598 for literal assignments in genPackBits (thanks to Frieder for
8604 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8606 Fixed bug #748310 (pointer to function type mishandled when the
8607 function name is omitted). Also fixed a SIGSEGV when a function
8608 attribute (reentrant, etc) is used on a non-function or on a
8609 function but misplaced before the parameter list.
8611 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8613 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8636 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8638 Made the constant following the "interrupt" keyword optional. If
8639 omitted, the function will not automatically be given an entry
8640 in the interrupt vector table (similar to #pragma NOIV, but
8641 less syntacticly kludgy). The interrupt number is also now
8642 range checked. Also fixed a bug in the high order bit example

9083 condition and ignore commands.
9085 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9087 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9088 is in parts still quite out of date, I did changes as far as I felt makes sense
9089 for a non-native english speaker.
9090 Please feel free to add to the manual or to correct my changes.
9091 * doc/Makefile: undid touching the date of intermediate tex files.
9093 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9108 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9110 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9111 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9112 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9113 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9116 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9118 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9119 the regression tests I'm not brave enough to enable 245.b, 245.c
9120 * doc/sdccman.lyx: added latex preamble for hyperref package.
9121 Using pdflatex this will give you a hyperlinked pdf file with
9122 bookmarks. (prepend '%' before /usepackage if this breaks something)
9124 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9138 Applied patch from bug 737905 (renamed yylineo to mylineno):
9145 * src/pic16/pcode.c: Cleaned warnings
9146 * src/pic16/pcodeflow.c: Cleaned warnings
9147 * src/pic16/pcoderegs.c: Cleaned warnings

9158 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9160 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9162 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9163 it can be defined with CFLAGS when running configure
9164 * src/SDCCmain.c: fixed compiling + linking with object files
9166 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9168 * configure.in: configure for pic16 port,
9169 added --disable-pic16-port
9170 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9171 * src/SDCCmain.c: linkOptions is changed to set *,
9172 added if/endif conditional macros to remove options help
9173 messages from optionsTable when a port is not configured, added
9174 support for the PIc16 port in the ports table, when executing
9175 the compiler with no port specified on command line, a default
9176 port is selected with the new macro DEFAULT_PORT which is
9177 defined in port.h, in setDefaultOptions() linkOptions is removed
9178 from initialization assignment, since now it is a set,
9179 parseCmdLine uses setParseWithComma for linkOptions, in
9180 linkEdit() linkOptions are accessed with new function indexSet()
9181 which returns the i'th item of a set variable. See SDCCset.c, in
9182 linkEdit() when calling buildCmdLine(), added linkOptions as
9183 last argument. Now users can pass arguments to gplink via the
9184 -Wl option, main() uses pic16glue() to glue up pic16 programs
9185 * src/SDCCpeeph.c: various changes to support pic16

9194 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9196 * src/pic16/glue.c: commented out some error producing lines
9197 * src/pic16/main.c: __config directives are commented out to stop
9198 gpasm complaining and test the linkage with gplink, _linkCmd and
9199 _asmCmd changed to be more gplink and gpasm friendly
9200 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9201 produced an error when parsed, peep rule 12 is added to utilize
9202 movff, but it is commented out since the pCode does not support
9203 yet a command with 2 address arguments
9205 2003-05-18 <johan AT balder>
9207 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9208 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9209 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9227 on entry now. Add tbreak. Other enhancements and fixes for use
9230 2003-05-12 Borut Razem <borut.razem AT siol.net>
9232 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9234 2003-05-11 Borut Razem <borut.razem AT siol.net>
9236 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9237 the path of bin directory, so that PATH is the only env. variable, which has to be set
9238 in case of standard installation.
9239 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10268 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10270 * in \sdcc\as\mcs51\ changed these files in order to create an
10271 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10272 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10273 following files to include the previous two files: aslink.dsp,
10274 Makefile.aslink, Makefile.bcc, and Makefile.in.
10276 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10277 .adb instead of .cdb
10279 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10281 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10282 value from option --iram-size.
10284 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10286 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10289 2002-09-18 <wiml AT hhhh.org>
10291 * SDCClrange.h: exposed setFromRange() and setToRange()
10292 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10293 packRegsForAccUse() (bug 542397)
10294 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10295 multiple times and emitting the fetch operations more than once
10296 added aopGetUsesAcc() function to allow binary operators to
10297 fetch their operands in the correct order; made genMinus() emit
10298 compact code for X = LITERAL - Y
10300 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10301 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10302 sprintf() in line 1267.
10304 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10305 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10308 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10309 Changes to aslink (All the changes are marked with 'JCF'):
10311 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10314 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10315 area BSEG. Also moves, if possible, the DATA area down into the internal
10316 ram so more space is available.
10318 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10321 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10322 not bytes. Function summary() which creates a memory usage summary
10323 file with extension .mem. Reports of overlaping stack and small stack
10324 size. If the space for the stack is less than 16 bytes aslink trows a
10327 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10328 the 8051. Option 'y' for memory summary output file.
10330 Changes to sdcc (All the changes are marked with 'JCF'):
10332 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10334 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10335 overlaying area for it (uses RegBankUsed[4]).
10337 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10338 bank zero as used by default. By default aslink locates the stack
10339 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10340 the creation of the .mem file. Delegates the allocation of data area
10341 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10342 the begining of the stack area to aslink.
10344 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10345 glue() in SDCCglue.c creates an area for it.
10347 2002-09-03 Borut Razem <borut.razem AT siol.net>
10348 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10349 sdcc/src/pic/glue.c:
10350 introduced atexit() handler for teporay files removal in case of
10351 errors, assertions, ...
10353 2002-08-29 Borut Razem <borut.razem AT siol.net>
10354 * sdcc/support/cpp2/auto-host_vc_in.h:
10355 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10356 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10357 Maybe there is a similar problem with BORLANDC? It should be checked!
10359 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10360 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10361 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10362 was not executed, and the compiler (cl) launched a warning:
10363 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10365 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10366 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10368 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10377 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10378 - added Release configuration in VS projects
10379 - review of compiler an linker options
10380 - VC .exe files are generated in bin_vc directory, not to interfere
10381 with binaries generated from other projects (cygwin, mingw, bcc ...)
10383 * sdcc/src/yacc.dsp: added
10385 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10386 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10387 and insert the version number definitions from .version
10389 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10391 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10401 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10403 2002-08-10 Borut Razem <borut.razem AT siol.net>
10404 * src/SDCCmain.c (main):
10405 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10406 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10407 The consequence was that some temporary files were not removed.
10410 unification of code in functions tempfilename() and tempfile():
10411 function tempnam() is defined in Visual Studio 6.0 and .NET
10413 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10415 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10416 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10417 - removed compiler command line option /WX: Treats all warnings as errors
10418 - update a list of source files, included into the project
10420 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10421 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10422 changed project type to Generic Project so that can be correcly converted to VS.NET project
10424 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10426 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10430 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10431 added return 0 statements after assert() to make compiler happy
10433 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10434 added newline in the def file to keep MSC compiler satisfied
10436 * sdcc/src/z80/gen.c:
10437 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10438 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10439 - solved MSC error in function aopDump()
10441 * sdcc_vc.h: define PREFIX as "\\sdcc"
10443 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10619 Previous fix was not good. basic blocks that have "break" or "return" are
10620 not really partof a loop , but live ranges used in these blocks should
