401 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
403 Enabled VPATH feature: changed nearly all Makefiles (149 files).
404 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
406 One basic decision: e.g. src/clean.mk includes further files. In order
407 to make this work there are two solutions:
408 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
409 run configure on them. This way they can use
410 'include $(srcdir)/port-clean.mk'
411 - always include clean.mk by the Makefile at the same level. To avoid
412 that `make clean` tries to include and build Makefile.dep the
413 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
414 implemented, because now even `make uninstall` doesn't create
415 Makefile.in. clean.mk could be eliminated by pasting it in
418 * debugger/mcs51/Makefile.in: build own objects from library sources
419 (SLIB, SDCC) in current directory
421 * configure, configure.in: renamed --disable-device-lib-build in
422 --disable-device-lib; added --enable-doc, the required tools are
423 searched by configure; added result message; the toolchain for the
424 belonging ports are now only built, if the port is enabled.
426 * support/regression/*: all output is written in directory gen, because
427 the fwk and ports directories don't livet in the build tree using vpath
429 * doc/sdccman.lyx: renamed --disable-device-lib-build to
430 --disable-device-lib, added --enable-doc, added section VPATH
432 * sim/ucsim/configure.in,
433 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
434 z80 are enabled by default
436 2006-04-24 Raphael Neider <rneider AT web.de>
438 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
439 to config word, "pic14_"-prefixed some extern functions
440 (pic14_emitConfigWord): emit __config directive(s) if assignment to
441 config word has been found
442 * src/pic/device.h: added prototypes
443 * src/pic/pcode.c: added "pic14_"-prefix where needed
444 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
446 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
448 (pic14emitRegularMap): ignore config words,
449 (pic14createInterruptVect): moved generating __config directives away
450 (picglue): have __config directives emitted
452 2006-04-24 Borut Razem <borut.razem AT siol.net>
454 * doc/Makefile: sync with nightly build makefile

459 registers that have not been assigned proper liveranges,
460 fixes #1469504 and #1474602,
461 (pCodeRegOptimizeRegUsage): fixed typo in comment
463 2006-04-24 Borut Razem <borut.razem AT siol.net>
465 * device/examples/main8051.c: deleted - it was removed from CVS
466 24.mar.2000 and after that modified 18.feb.2001, so it reappered
467 after the transition to Subversion
468 * src/SDCCalloc.h: deleted - it was removed from CVS
469 3.feb.2001 and after that modified 18.feb.2001, so it reappered
470 after the transition to Subversion

724 the left operand is shorter than the result (c* = lit-c* + int),
726 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
729 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
731 * src/.version: increased version number to 2.5.5
732 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
733 linking is done manually in pic16 port's _linkEdit,
734 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
735 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

3114 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3115 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3116 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3117 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3118 always available in leading double underscore form. The C99 support is
3119 mostly missing, but it's a start.
3120 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3121 reserved identifier "__data".
3123 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3199 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3201 * device/lib/printf_large.c: removed inline assembly for portability and
3202 readability. Use printf_fast if speed or size are more important.
3203 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3204 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3206 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3208 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3209 prevent compiler warning
3211 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3213 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3214 moved to level 0 and declared as static. Also they are explicit
3215 placed in access bank. This was necessery because some times they
3216 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3217 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3218 optimizations. Currently only compare to unsigned char is implemented,
3219 * src/pic16/gen.c: added fReturnIdx array,
3220 * (struct resolvedIfx) is moved to gen.h and made public,
3221 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3222 * (aopForSym): added an optimization to directly store in stack of
3223 the operand of a SEND iCode,
3224 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3225 but as registers instead (AOP_REG) using the fReturnIdx array,
3226 * (pic16_freeAsmop): remove the freed register from the
3227 _G.sregsAlloc field,
3228 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3229 a compare of 'WREG',
3230 * (pic16_popGetTempRegCond): changed function prototype, now
3231 function takes also a bitVector argument v which holds the current
3232 set of registers that are allocated for stack access by aopForSym,
3233 registers allocated in aopForSym for accessing stack symbols are not
3234 any more part of the functions usedRegs field,
3235 * (genCall): some times aopOp is called for a stack variable to be
3236 send, aopForSym might perform the push, if this is true make sure
3237 that genCall doesn't push the variable twice by testing _G.resDirect,
3238 * (genFunction): changed testing for unspecified interrupt number
3239 from 256 to INTNO_UNSPEC,
3240 * modified selection scheme of frame pointer generation. Previously
3241 if function did use local registers a frame pointer was generated,
3242 now a frame pointer is generated only if function has arguments
3243 (that need PLUSW2 register access), or has stack arguments, or the
3244 compiler is not instructed to omit the frame pointer,
3245 * (genEndFunction): before restoring local registers that were saved
3246 in the function preamble, also restore the registers that *might*
3247 have been allocated for stack access,
3248 * (genRet): removed some old comments,
3249 * (genCmp, the active (RN's) version): added a call to the
3250 pic16_genCmp_special function to perform the compare with a more
3251 robust and optimized way,
3252 * (genInline): a feature has been added in inline code generation,
3253 which allows a wildcard variable substitution when writing inline
3254 assembly. Code is incomplete and experimental therefore undocumented,
3255 * (genCast): changed order of aopOp for result and right to allow
3256 aopForSym to directly load the result if possible,
3257 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3258 perform an optimized compare on some selected special occasions,
3259 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3260 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3261 generate an IVT any more,
3262 * src/pic16/main.c (pic16_optionsTable): added command line option
3264 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3265 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3267 * src/pic16/NOTES: Raphael Neider added in list of active developers
3268 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3269 jumptable_end to prevent bug #,
3270 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3271 inCond and outCond fields,
3272 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3273 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3274 turn off register spilling,
3275 * (packRegsForOneUse): synced with other ports' versions although it
3276 is not used currently,
3277 * (pic16_packRegisters): added an optimization while reading
3278 structure bitfields, some registers may be saved (malloc code is
3279 decreased by 80 bytes)
3281 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3283 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3284 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3285 this can be optimized more?
3287 2005-03-10 Raphael Neider <rneider AT web.de>
3289 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3290 genNearPointerGet): (hopefully) fixed access to bitfields via
3291 pointers (p->bitN = x; and x = p->bitN; failed)
3293 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3904 2004-12-02 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3906 * src/SDCCpeeph.c (callFuncByName): support combined peephole rule
3908 (setFromConditionArgs): friendly operand parser for peephole rules,
3909 (operandBaseName, operandsNotRelated): new peephole condition
3910 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3911 architecture specific register naming into account, handles n-way
3912 comparisons, and supports quoted literals
3913 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3915 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3923 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3925 Adding support for replacing ljmps with sjmps in jumptables
3926 generated for switch statements. For now you need to set the
3927 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3928 Now 4 algorithms for mcs51 jumptable generation are used:
3929 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3930 addresses loaded pc-relative for up to 112 cases and stack-pushing
3931 target addresses loaded with offset from dptr for up to 256 cases.
3933 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3934 * src/mcs51/main.c: adapted constants for switch table generation
3935 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3957 Large cummulative patch for pic16 port.
3958 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3959 to call when a stack overflow occurs,
3960 * (malloc.h): added CVS Id tag,
3961 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3963 * added libc directory. The current version of LibC contains string
3964 functions, ctype functions and macros and some functions of the
3965 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3966 be extensively tested in the future. Standard disclaimer here.
3967 Library is not automatically build yet. But one can build it by
3968 invoking 'make' inside the libc directory.
3969 * added ADC library under libio. Preliminary version yet.
3971 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3978 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3979 * (pic16_storeForReturn): optimized return of 0,
3980 * (genCmp): experimental code for new genCmp which uses PIC18's
3981 special compare&skip instructions. Initial tests fail some times
3982 with variables grater than 1 byte in size, so new code is disabled,
3983 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3985 * (genCast): began a fix to optimize the casting of a bit to another
3986 bit, now assigning a bitfield to another bitfield will fail, sorry,
3987 * src/pic16/main.c: disabled the use of lr-support feature,
3988 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3989 * added some function prototypes, added function _debugf prototype,

3991 bits with offset (case PO_GPR_BIT),
3992 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3994 * (isBankInstruction): modified to return 0 for no banking instruction,
3995 and 1 for banking instruction,
3996 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3997 caused stop processing pCodes after a inline assembly block,
3998 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3999 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4000 registers when it shouldn't,
4001 * src/pic16/ralloc.c (allocReg): add preliminary support for
4002 supporting a limited set of temporary registers,
4004 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4006 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4007 genDataPointerSet): ensure assignments always copy in MSB to LSB
4009 (loadRegFromAop): recognize CLRH optimization,
4010 (genFunction): optimize RECEIVE iCodes in reentrant functions
4012 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4014 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4015 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4017 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
4018 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
4019 contiguous with data

4024 * device/lib/_gptrgetc.c (_gptrgetc),
4025 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4026 instead of sjmp to ret

4028 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4030 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7000 * src/SDCCval.c (cheapestVal): added missing checks
7001 * src/SDCCicode.c (usualBinaryConversions): fixed condition
7002 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
7004 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
7006 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
7009 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7011 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7012 loaded with the linker search paths (-L arguments) and the libraries
7013 to be linked with the current source (-l arguments). Changes
7014 currently will affect only the pic16 port.
7015 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7016 include path the port specific paths and port specific libraries,
7017 * gplink command now contains the $3 argument,
7018 * src/pic16/device.h,
7019 * src/pic16/device.c,: structure PIC_device is made public and
7020 renamed to PIC16_device, the same for variable Pics which is renamed
7021 to Pics16. Updated all references to them.
7022 * src/pic16/glue.c (pic16glue): corrected bug with code
7023 initialization which bypassed the variable initializations block.
7025 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7026 COMPILE_FLAGS and added the --nostdinc option
7028 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7030 * device/include/mc68hc908jb8.h: Register defs for another member
7031 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7033 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7035 Documenting changes from previous commits.
7036 * configure.in (version 1.56),
7037 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7038 when generating output files to configure the pic16 library,
7039 but now I've commented it out, since gputils aren't installed in the
7040 SF compile farm, so library won't compile
7042 * device/lib/Makefile.in (version 1.56): initially I've added in
7043 target 'all' the prerequestive 'model-pic16' so it compiled the
7044 pic16 library, but now I've commented it out for the same reasons
7046 * added targets 'model-pic16' and 'objects-pic16' to compile the
7048 * added target 'port-specific-objects-pic16' to handle the
7049 generated libraries and copy them into the build/ directory
7050 * added target 'clean-intermediate-pic16' to clean intermediate
7051 files into pic16 directory
7052 * in target 'installdirs' added line to create directory pic16 in
7053 the installation path
7055 * device/include/Makefile.in (version 1.11): in target 'install'
7056 added lines to copy all header files to installation path,
7057 * in target 'installdirs' added line create directory for pic16
7058 headers in the installation path
7060 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7073 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7074 option so that it actually works. Made it specific to the z80, since
7075 the gbz80 doesn't have these kinds of I/O ports.
7077 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7079 * device/include/z180.h,

7086 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7087 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7088 portmode; added deprecation warning for bank= and protmode= forms.
7089 Also, guard against buffer overflow.
7090 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7092 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7094 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7095 changed interrupt vector table generation to only emit declared vectors.
7096 * device/include/Makefile.in: added missing backslash
7097 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7101 Mainly changes to support compilation of the device libraries
7102 * src/pic16/device.c: stack is allocated via symbol and not
7103 via literal number. The symbol is placed in the corresponding
7104 position of the data ram
7105 * (pic16_dump_section): relocatable and absolute uninitialized
7106 data are now emitted in sorted order to reduce section naming,
7107 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7108 weren't marked as being in the access bank,
7110 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7112 Added portion of GNU PIC Library under the directory
7113 device/include/pic16 and device/lib/pic16. These files
7114 contain the declarations of SFRs for the PIC18Fxx2 devices.
7115 The directory is initialized via configure from toplevel.
7117 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7119 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7120 the spilllocations to be compared correctly
7122 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7124 * src/SDCCast.c (decorateType): fixed bug introduced today
7126 2004-01-12 Borut Razem <borut.razem AT siol.net>
7128 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7131 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7133 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7134 in simpler and even better code
7136 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7138 * src/SDCCicode.c (operandOperation): fixed bug #874819

7142 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7144 * doc/sdccman.lyx: Moved and added some sections, small changes
7145 all over. Telling LaTeX to be less strict with word spacing
7146 to better keep the right margin. Changed some notes about
7147 maintainance of the ports in section 3.2.1 - is it OK like this?
7149 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7186 UPPER for immediate operands,
7187 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7189 * src/pic16/peeph.def: all peepholes with movff are commented out,
7190 because there is a problem in the pcode peep optimizer,
7191 * src/pic16/ralloc.c: the register allocator can now reuse local

7193 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7195 Added file src/pic16/NOTES with information about program writing on
7196 the current port version.

7268 2004-01-07 Borut Razem <borut.razem AT siol.net>
7270 * support/scripts/sdcc.nsi: update PATH
7271 * support/scripts/sdcc.ico: craeted

7284 include information about variables allocated to the overlay
7287 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7289 * as/mcs51/lkmain.c: Help about -Y option

7301 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7303 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7304 (default behaviour).
7306 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7308 A python script to validate compiler diagnostic messages. It can be
7309 used to verify that sdcc complains about bad c source code and
7310 gives a good location of the error.
7311 * support/valdiag/Makefile,
7312 * support/valdiag/valdiag.py,
7313 * support/valdiag/tests/*
7315 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7330 Bug reported from Jesus Calvino-Fraga
7332 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7334 * sdcc.spec: updated
7335 * device/include/Makefile.in: don't install CVS directories
7336 * device/lib/Makefile.in: added removal of CVS directories after install
7337 * doc/Makefile: fixed install, added local_icons
7338 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7339 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7340 * src/ds390/gen.c (genRightShift): fixed bug #870788
7341 * src/SDCCast.c (decorateType): fixed bug #870781
7343 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7345 PIC16 port related changes:
7346 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7347 added variable stackPos,
7349 * gen.c: genCall, assignResultValue: added support for
7350 pushing/retrieving function parameters to/from stack,
7351 genFunction,genEndFunction: setup stack frame for the
7353 genAddrOf: will be changed according to bug 863624
7355 * added files genutils.c and genutils.h which contain gen*
7356 debugged and optimised functions extracted from gen.c
7358 * glue.c: added variable 'externs' which holds extern symbols,
7359 pic16emitRegularMap: is modified to properly handle relocatable
7360 symbols under the new scheme,
7361 pic16createInterruptVect: is modified
7362 pic16printPublics: is modified to emit 'global' assembler directives,
7363 added pic16_printExterns to print extern symbols,
7364 pic16glue: initializes stack/frame pointer in the beginning of
7365 the assembly output. Temporary hack, will be corrected later,
7366 because gplink yet does not support stack and SDCC does not
7367 yet support a type of crt0.o object to create the final binary.
7369 * Removed many lines that contain 8051 legacy code.
7370 * The code is finally placed under a 'code' directive.
7371 * Added port specific options.
7373 * _process_pragma: simplified since now we do not need *special*
7374 include file to define SFR registers. But a separate header
7375 will be needed. This will be developed later.
7376 * _pic16_parseOptions: added, parses port specific options:
7377 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7378 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7379 --preplace-udata-with=
7381 * _pic16_setDefaultOptions: modified to initialize section names,
7382 but hack is temporarly out of order since it needs improvement.
7383 * _pic16_genAssemblerPreamble: configuration words are emitted by
7384 their address instead of their name. This part is incomplete and
7385 supports only the 18Fxx2 devices. Other devices will emit an error
7386 during assembly since they do not contain the same set of config
7388 * _pic16_genIVT: is modified,
7390 * pcode.c: added definitions for some hardware registers that are needed
7392 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7393 All PCI entries are updated. Now LFSR is supported.
7394 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7395 * added pic16_newpCodeOpLit2 to support instructions with
7396 two literal arguments
7397 * pic16_pCode2str: corrected code that emits assembler instructions
7398 with two literal operands and those that have an access bit modifier
7399 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7400 this fixes a bug which caused some labels to be lost, when an
7401 assembler directive was added, i.e. banksel,
7402 * pic16_FixRegisterBanking: improved logic that causes the insertion
7404 * InlineFunction: functions that are called once, are not any more
7405 inlined. This can be a port option in the future,
7407 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7409 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7410 hold the corresponding uninitialized symbols,
7411 * pic16_allocProcessorRegister: registers have explicit marked the
7413 * pic16_allocInternalRegister: registers are explicit marked as
7415 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7416 processing list, so bit registers were lost,
7419 * ralloc.h: added field 'accessBank' and original symbol operand
7420 in register definition,
7421 * removed the field isMapped from register definition,
7423 ** Several functions have been removed from various sources:
7424 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7425 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7426 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7427 pic16_assignRelocatableRegisters
7429 ** others have been introduced:
7430 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7431 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7433 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7435 * support/scripts/inc2h.pl: changed definition of BIT_AT
7436 to emit 'sbit at' instead of 'bit at'. This was a request.
7438 PIC16 port related preliminary changes:
7439 * gen.c: prefixed function popRegFromString with
7440 pic16_ and all references to it corrected
7441 * pcode.c: all pic16_pc_* hardware registers prefixed
7442 with underscore (_),
7443 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7444 * ralloc.c: newReg(): when register is REG_SFR then
7445 set address to rIdx,
7446 pic16_allocProcessorRegister(): marks register wasUsed=0
7447 pic16_writeUsedRegs(): added a call to assign processor
7448 registers via pic16_assignFixedRegisters
7450 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7452 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7453 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7454 variables in unused register banks. Also the SSEG is placed
7455 wherever there is enough space for it, and IDATA can be anywhere
7456 in internal RAM. For now compile using -Wl-Y[stack_size].
7457 The mem file is different for this option as well, since it
7458 makes no sense of talking about DSEG lenght.
7460 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7462 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7463 in certain cases, e.g. when ROM assignment, patch provided
7464 from Albert den Haan.
7466 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8487 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8489 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8490 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8491 type for bits was changed. It resulted in bit variables becoming
8492 global, which is not permitted in PIC 14 assembly output.
8494 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8496 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8509 A few small changes that speed up the peephole optimizer.
8513 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8515 Try to make the peephole optimizer smarter by maintaining
8516 an association between the assembly source code and the
8517 iCodes that originated them. Put this information to use
8518 with a new peephole rule condition "notVolatile" so that
8519 the rules can be aggressive yet still safe.
8524 * src/mcs51/peeph.def
8526 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8530 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8531 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8532 if the left or right operand symbols have the accuse flag set.
8534 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8536 Changed the type of the result of the ! (NOT) operator to char;
8537 previously it returned the same type as the source. This allows
8538 us to eliminate all the genFloatNot functions (all of its target
8539 implementations were very buggy) since !float can use the same
8542 * src/SDCCicode.c (ast2iCode): ! returns char

8551 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8552 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8553 during interrupts. Ensure WSAVE is located at a shared bank address.
8554 2. Fixed page selection in some places
8555 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8556 the registers name strings.
8557 4. Fixed "signed / unsigned compare" compiler warnings.
8558 5. The PIC port manages its own allocation of the general purpose
8559 registers, but makes no attempt to reuse them. As a result when
8560 compiling it soon runs out of general purpose registers. Some
8561 additional code was added to the files pcode.c and device.c to walk
8562 through the function call tree and rename the registers so that they
8572 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8573 genPlus() & genMinus() when the result is the same as left or right

8579 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8581 Made bitfield a distinct type from bit so that bitfields
8582 convert as per ANSI C and bits retain their traditional
8583 boolean style behaviour. Implemented bitfield support in
8591 * src/ds390/gen.c: bit v bitfield split
8592 * src/z80/gen.c: New support for bitfields
8593 * support/regression/tests/bitfields.c: reenabled z80,
8596 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8598 Rules 246.x, 247.x relate to bitfields, the others speed up
8599 access to xdata mapped I/O devices.
8601 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8603 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8605 Cleaned up genPackBits and genUnpackBits and added two helper
8606 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8607 for literal assignments in genPackBits (thanks to Frieder for
8613 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8615 Fixed bug #748310 (pointer to function type mishandled when the
8616 function name is omitted). Also fixed a SIGSEGV when a function
8617 attribute (reentrant, etc) is used on a non-function or on a
8618 function but misplaced before the parameter list.
8620 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8622 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8645 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8647 Made the constant following the "interrupt" keyword optional. If
8648 omitted, the function will not automatically be given an entry
8649 in the interrupt vector table (similar to #pragma NOIV, but
8650 less syntacticly kludgy). The interrupt number is also now
8651 range checked. Also fixed a bug in the high order bit example

8667 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8669 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8670 be re-activated by defining REDUCE_LITERALS)
8671 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8672 unsigned, but are signed by default
8673 * src/SDCCval.c (constVal): rearranged
8674 * src/SDCCval.c (valMod): preliminary fix
8675 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9169 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9171 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9172 it can be defined with CFLAGS when running configure
9173 * src/SDCCmain.c: fixed compiling + linking with object files
9175 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9178 added --disable-pic16-port
9179 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9180 * src/SDCCmain.c: linkOptions is changed to set *,
9181 added if/endif conditional macros to remove options help
9182 messages from optionsTable when a port is not configured, added
9183 support for the PIc16 port in the ports table, when executing
9184 the compiler with no port specified on command line, a default
9185 port is selected with the new macro DEFAULT_PORT which is
9186 defined in port.h, in setDefaultOptions() linkOptions is removed
9187 from initialization assignment, since now it is a set,
9188 parseCmdLine uses setParseWithComma for linkOptions, in
9189 linkEdit() linkOptions are accessed with new function indexSet()
9190 which returns the i'th item of a set variable. See SDCCset.c, in
9191 linkEdit() when calling buildCmdLine(), added linkOptions as
9192 last argument. Now users can pass arguments to gplink via the
9193 -Wl option, main() uses pic16glue() to glue up pic16 programs
9194 * src/SDCCpeeph.c: various changes to support pic16

9203 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9205 * src/pic16/glue.c: commented out some error producing lines
9206 * src/pic16/main.c: __config directives are commented out to stop
9207 gpasm complaining and test the linkage with gplink, _linkCmd and
9208 _asmCmd changed to be more gplink and gpasm friendly
9209 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9210 produced an error when parsed, peep rule 12 is added to utilize
9211 movff, but it is commented out since the pCode does not support
9212 yet a command with 2 address arguments
9214 2003-05-18 <johan AT balder>
9216 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9236 on entry now. Add tbreak. Other enhancements and fixes for use
9239 2003-05-12 Borut Razem <borut.razem AT siol.net>
9241 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9243 2003-05-11 Borut Razem <borut.razem AT siol.net>
9245 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9246 the path of bin directory, so that PATH is the only env. variable, which has to be set
9247 in case of standard installation.
9248 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10277 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10279 * in \sdcc\as\mcs51\ changed these files in order to create an
10280 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10281 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10282 following files to include the previous two files: aslink.dsp,
10283 Makefile.aslink, Makefile.bcc, and Makefile.in.
10285 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10286 .adb instead of .cdb
10288 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10290 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10291 value from option --iram-size.
10293 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10295 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10298 2002-09-18 <wiml AT hhhh.org>
10300 * SDCClrange.h: exposed setFromRange() and setToRange()
10301 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10302 packRegsForAccUse() (bug 542397)
10303 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10304 multiple times and emitting the fetch operations more than once
10305 added aopGetUsesAcc() function to allow binary operators to
10306 fetch their operands in the correct order; made genMinus() emit
10307 compact code for X = LITERAL - Y
10309 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10310 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10311 sprintf() in line 1267.
10313 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10314 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10317 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10318 Changes to aslink (All the changes are marked with 'JCF'):
10320 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10323 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10324 area BSEG. Also moves, if possible, the DATA area down into the internal
10325 ram so more space is available.
10327 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10330 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10331 not bytes. Function summary() which creates a memory usage summary
10332 file with extension .mem. Reports of overlaping stack and small stack
10333 size. If the space for the stack is less than 16 bytes aslink trows a
10336 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10337 the 8051. Option 'y' for memory summary output file.
10339 Changes to sdcc (All the changes are marked with 'JCF'):
10341 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10343 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10344 overlaying area for it (uses RegBankUsed[4]).
10346 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10347 bank zero as used by default. By default aslink locates the stack
10348 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10349 the creation of the .mem file. Delegates the allocation of data area
10350 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10351 the begining of the stack area to aslink.
10353 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10354 glue() in SDCCglue.c creates an area for it.
10356 2002-09-03 Borut Razem <borut.razem AT siol.net>
10357 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10358 sdcc/src/pic/glue.c:
10359 introduced atexit() handler for teporay files removal in case of
10360 errors, assertions, ...
10362 2002-08-29 Borut Razem <borut.razem AT siol.net>
10363 * sdcc/support/cpp2/auto-host_vc_in.h:
10364 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10365 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10366 Maybe there is a similar problem with BORLANDC? It should be checked!
10368 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10369 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10370 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10371 was not executed, and the compiler (cl) launched a warning:
10372 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10374 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10375 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10377 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10384 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10385 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10386 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10387 - added Release configuration in VS projects
10388 - review of compiler an linker options
10389 - VC .exe files are generated in bin_vc directory, not to interfere
10390 with binaries generated from other projects (cygwin, mingw, bcc ...)
10392 * sdcc/src/yacc.dsp: added
10394 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10395 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10396 and insert the version number definitions from .version
10398 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10400 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10401 added - genarate auto-host.h using auto-host_vc_in.h as template
10404 removed from CVS, generated automatically
10406 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10407 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10409 2002-08-11 Borut Razem <borut.razem AT siol.net>
10410 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10412 2002-08-10 Borut Razem <borut.razem AT siol.net>
10413 * src/SDCCmain.c (main):
10414 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10415 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10416 The consequence was that some temporary files were not removed.
10419 unification of code in functions tempfilename() and tempfile():
10420 function tempnam() is defined in Visual Studio 6.0 and .NET
10422 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10424 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10425 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10426 - removed compiler command line option /WX: Treats all warnings as errors
10427 - update a list of source files, included into the project
10429 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10430 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10431 changed project type to Generic Project so that can be correcly converted to VS.NET project
10433 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10435 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10439 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10440 added return 0 statements after assert() to make compiler happy
10442 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10443 added newline in the def file to keep MSC compiler satisfied
10445 * sdcc/src/z80/gen.c:
10446 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10447 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10448 - solved MSC error in function aopDump()
10450 * sdcc_vc.h: define PREFIX as "\\sdcc"
10452 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10625 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10627 * sdcc/src/SDCCloop.c:
10628 Previous fix was not good. basic blocks that have "break" or "return" are
10629 not really partof a loop , but live ranges used in these blocks should
10630 be live thru the entire loop, so set partOfLoop but don't add them to
