393 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
395 Enabled VPATH feature: changed nearly all Makefiles (149 files).
396 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
398 One basic decision: e.g. src/clean.mk includes further files. In order
399 to make this work there are two solutions:
400 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
401 run configure on them. This way they can use
402 'include $(srcdir)/port-clean.mk'
403 - always include clean.mk by the Makefile at the same level. To avoid
404 that `make clean` tries to include and build Makefile.dep the
405 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
406 implemented, because now even `make uninstall` doesn't create
407 Makefile.in. clean.mk could be eliminated by pasting it in
410 * debugger/mcs51/Makefile.in: build own objects from library sources
411 (SLIB, SDCC) in current directory
413 * configure, configure.in: renamed --disable-device-lib-build in
414 --disable-device-lib; added --enable-doc, the required tools are
415 searched by configure; added result message; the toolchain for the
416 belonging ports are now only built, if the port is enabled.
418 * support/regression/*: all output is written in directory gen, because
419 the fwk and ports directories don't livet in the build tree using vpath
421 * doc/sdccman.lyx: renamed --disable-device-lib-build to
422 --disable-device-lib, added --enable-doc, added section VPATH
424 * sim/ucsim/configure.in,
425 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
426 z80 are enabled by default
428 2006-04-24 Raphael Neider <rneider AT web.de>
430 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
431 to config word, "pic14_"-prefixed some extern functions
432 (pic14_emitConfigWord): emit __config directive(s) if assignment to
433 config word has been found
434 * src/pic/device.h: added prototypes
435 * src/pic/pcode.c: added "pic14_"-prefix where needed
436 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
438 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
440 (pic14emitRegularMap): ignore config words,
441 (pic14createInterruptVect): moved generating __config directives away
442 (picglue): have __config directives emitted
444 2006-04-24 Borut Razem <borut.razem AT siol.net>
446 * doc/Makefile: sync with nightly build makefile

452 fixes #1469504 and #1474602,
453 (pCodeRegOptimizeRegUsage): fixed typo in comment
455 2006-04-24 Borut Razem <borut.razem AT siol.net>
457 * device/examples/main8051.c: deleted - it was removed from CVS
458 24.mar.2000 and after that modified 18.feb.2001, so it reappered
459 after the transition to Subversion
460 * src/SDCCalloc.h: deleted - it was removed from CVS
461 3.feb.2001 and after that modified 18.feb.2001, so it reappered

716 the left operand is shorter than the result (c* = lit-c* + int),
718 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
721 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
723 * src/.version: increased version number to 2.5.5
724 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
725 linking is done manually in pic16 port's _linkEdit,
726 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
727 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

3106 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3107 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3108 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3109 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3110 always available in leading double underscore form. The C99 support is
3111 mostly missing, but it's a start.
3112 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3113 reserved identifier "__data".
3115 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3191 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3193 * device/lib/printf_large.c: removed inline assembly for portability and
3194 readability. Use printf_fast if speed or size are more important.
3195 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3196 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3198 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3200 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3201 prevent compiler warning
3203 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3205 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3206 moved to level 0 and declared as static. Also they are explicit
3207 placed in access bank. This was necessery because some times they
3208 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3209 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3210 optimizations. Currently only compare to unsigned char is implemented,
3211 * src/pic16/gen.c: added fReturnIdx array,
3212 * (struct resolvedIfx) is moved to gen.h and made public,
3213 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3214 * (aopForSym): added an optimization to directly store in stack of
3215 the operand of a SEND iCode,
3216 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3217 but as registers instead (AOP_REG) using the fReturnIdx array,
3218 * (pic16_freeAsmop): remove the freed register from the
3219 _G.sregsAlloc field,
3220 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3221 a compare of 'WREG',
3222 * (pic16_popGetTempRegCond): changed function prototype, now
3223 function takes also a bitVector argument v which holds the current
3224 set of registers that are allocated for stack access by aopForSym,
3225 registers allocated in aopForSym for accessing stack symbols are not
3226 any more part of the functions usedRegs field,
3227 * (genCall): some times aopOp is called for a stack variable to be
3228 send, aopForSym might perform the push, if this is true make sure
3229 that genCall doesn't push the variable twice by testing _G.resDirect,
3230 * (genFunction): changed testing for unspecified interrupt number
3231 from 256 to INTNO_UNSPEC,
3232 * modified selection scheme of frame pointer generation. Previously
3233 if function did use local registers a frame pointer was generated,
3234 now a frame pointer is generated only if function has arguments
3235 (that need PLUSW2 register access), or has stack arguments, or the
3236 compiler is not instructed to omit the frame pointer,
3237 * (genEndFunction): before restoring local registers that were saved
3238 in the function preamble, also restore the registers that *might*
3239 have been allocated for stack access,
3240 * (genRet): removed some old comments,
3241 * (genCmp, the active (RN's) version): added a call to the
3242 pic16_genCmp_special function to perform the compare with a more
3243 robust and optimized way,
3244 * (genInline): a feature has been added in inline code generation,
3245 which allows a wildcard variable substitution when writing inline
3246 assembly. Code is incomplete and experimental therefore undocumented,
3247 * (genCast): changed order of aopOp for result and right to allow
3248 aopForSym to directly load the result if possible,
3249 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3250 perform an optimized compare on some selected special occasions,
3251 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3252 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3253 generate an IVT any more,
3254 * src/pic16/main.c (pic16_optionsTable): added command line option
3256 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3257 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3259 * src/pic16/NOTES: Raphael Neider added in list of active developers
3260 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3261 jumptable_end to prevent bug #,
3262 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3263 inCond and outCond fields,
3264 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3265 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3266 turn off register spilling,
3267 * (packRegsForOneUse): synced with other ports' versions although it
3268 is not used currently,
3269 * (pic16_packRegisters): added an optimization while reading
3270 structure bitfields, some registers may be saved (malloc code is
3271 decreased by 80 bytes)
3273 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3275 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3276 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3277 this can be optimized more?
3279 2005-03-10 Raphael Neider <rneider AT web.de>
3281 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3282 genNearPointerGet): (hopefully) fixed access to bitfields via
3283 pointers (p->bitN = x; and x = p->bitN; failed)
3285 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3900 (setFromConditionArgs): friendly operand parser for peephole rules,
3901 (operandBaseName, operandsNotRelated): new peephole condition
3902 "operandsNotRelated" -- similar to "operandsNotSame", but takes
3903 architecture specific register naming into account, handles n-way
3904 comparisons, and supports quoted literals
3905 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
3907 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3909 * src/mcs51/peeph.def: fixed bug #1076940
3911 2004-12-02 Slade Rich <slade_rich AT users.sourceforge.net>
3913 * device/include/pic/pic16f877.h : added an include file for the PIC16F877 device.
3915 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3917 Adding support for replacing ljmps with sjmps in jumptables
3918 generated for switch statements. For now you need to set the
3919 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3920 Now 4 algorithms for mcs51 jumptable generation are used:
3921 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3922 addresses loaded pc-relative for up to 112 cases and stack-pushing
3923 target addresses loaded with offset from dptr for up to 256 cases.
3925 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3926 * src/mcs51/main.c: adapted constants for switch table generation
3927 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3949 Large cummulative patch for pic16 port.
3950 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3951 to call when a stack overflow occurs,
3952 * (malloc.h): added CVS Id tag,
3953 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3955 * added libc directory. The current version of LibC contains string
3956 functions, ctype functions and macros and some functions of the
3957 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3958 be extensively tested in the future. Standard disclaimer here.
3959 Library is not automatically build yet. But one can build it by
3960 invoking 'make' inside the libc directory.
3961 * added ADC library under libio. Preliminary version yet.
3963 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3970 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3971 * (pic16_storeForReturn): optimized return of 0,
3972 * (genCmp): experimental code for new genCmp which uses PIC18's
3973 special compare&skip instructions. Initial tests fail some times
3974 with variables grater than 1 byte in size, so new code is disabled,
3975 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3977 * (genCast): began a fix to optimize the casting of a bit to another
3978 bit, now assigning a bitfield to another bitfield will fail, sorry,
3979 * src/pic16/main.c: disabled the use of lr-support feature,
3980 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3981 * added some function prototypes, added function _debugf prototype,
3982 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3983 bits with offset (case PO_GPR_BIT),
3984 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3986 * (isBankInstruction): modified to return 0 for no banking instruction,
3987 and 1 for banking instruction,
3988 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3989 caused stop processing pCodes after a inline assembly block,
3990 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3991 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3992 registers when it shouldn't,
3993 * src/pic16/ralloc.c (allocReg): add preliminary support for
3994 supporting a limited set of temporary registers,
3996 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3998 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3999 genDataPointerSet): ensure assignments always copy in MSB to LSB
4001 (loadRegFromAop): recognize CLRH optimization,
4002 (genFunction): optimize RECEIVE iCodes in reentrant functions
4004 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4006 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4007 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4009 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4015 * device/lib/_gptrget.c (_gptrget),
4016 * device/lib/_gptrgetc.c (_gptrgetc),
4017 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4018 instead of sjmp to ret
4019 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4020 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4022 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7003 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7004 loaded with the linker search paths (-L arguments) and the libraries
7005 to be linked with the current source (-l arguments). Changes
7006 currently will affect only the pic16 port.
7007 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7008 include path the port specific paths and port specific libraries,
7009 * gplink command now contains the $3 argument,
7010 * src/pic16/device.h,
7011 * src/pic16/device.c,: structure PIC_device is made public and
7012 renamed to PIC16_device, the same for variable Pics which is renamed
7013 to Pics16. Updated all references to them.
7014 * src/pic16/glue.c (pic16glue): corrected bug with code
7015 initialization which bypassed the variable initializations block.
7017 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7018 COMPILE_FLAGS and added the --nostdinc option
7020 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7022 * device/include/mc68hc908jb8.h: Register defs for another member
7023 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7025 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7027 Documenting changes from previous commits.
7028 * configure.in (version 1.56),
7029 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7030 when generating output files to configure the pic16 library,
7031 but now I've commented it out, since gputils aren't installed in the
7032 SF compile farm, so library won't compile
7034 * device/lib/Makefile.in (version 1.56): initially I've added in
7035 target 'all' the prerequestive 'model-pic16' so it compiled the
7036 pic16 library, but now I've commented it out for the same reasons
7038 * added targets 'model-pic16' and 'objects-pic16' to compile the
7040 * added target 'port-specific-objects-pic16' to handle the
7041 generated libraries and copy them into the build/ directory
7042 * added target 'clean-intermediate-pic16' to clean intermediate
7043 files into pic16 directory
7044 * in target 'installdirs' added line to create directory pic16 in
7045 the installation path
7047 * device/include/Makefile.in (version 1.11): in target 'install'
7048 added lines to copy all header files to installation path,
7049 * in target 'installdirs' added line create directory for pic16
7050 headers in the installation path
7052 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7065 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7066 option so that it actually works. Made it specific to the z80, since
7067 the gbz80 doesn't have these kinds of I/O ports.
7069 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7071 * device/include/z180.h,

7084 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7086 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7087 changed interrupt vector table generation to only emit declared vectors.
7088 * device/include/Makefile.in: added missing backslash
7089 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7093 Mainly changes to support compilation of the device libraries
7094 * src/pic16/device.c: stack is allocated via symbol and not
7095 via literal number. The symbol is placed in the corresponding
7096 position of the data ram
7097 * (pic16_dump_section): relocatable and absolute uninitialized
7098 data are now emitted in sorted order to reduce section naming,
7099 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7100 weren't marked as being in the access bank,
7102 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7104 Added portion of GNU PIC Library under the directory
7105 device/include/pic16 and device/lib/pic16. These files
7106 contain the declarations of SFRs for the PIC18Fxx2 devices.
7107 The directory is initialized via configure from toplevel.
7109 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7111 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7112 the spilllocations to be compared correctly
7114 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7116 * src/SDCCast.c (decorateType): fixed bug introduced today
7118 2004-01-12 Borut Razem <borut.razem AT siol.net>

7136 * doc/sdccman.lyx: Moved and added some sections, small changes
7137 all over. Telling LaTeX to be less strict with word spacing
7138 to better keep the right margin. Changed some notes about
7139 maintainance of the ports in section 3.2.1 - is it OK like this?
7141 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7143 SDCC source changes:
7144 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7178 UPPER for immediate operands,
7179 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7181 * src/pic16/peeph.def: all peepholes with movff are commented out,
7182 because there is a problem in the pcode peep optimizer,
7183 * src/pic16/ralloc.c: the register allocator can now reuse local
7184 function symbols for another function. This saves register usage.
7185 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7187 Added file src/pic16/NOTES with information about program writing on
7188 the current port version.

7197 * src/SDCCmain.c : fixed #872250: -l command line defined library
7198 files are scanned before standard library files
7200 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7217 gen51Code): more efficient parameter receive for --model-large
7220 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7223 * src/z80/main.c: added missed needLinkerScript flags (more than
7224 one port structure defined in these file)
7225 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7241 needLinkerScript flag
7243 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7244 * src/pic/glue.c: added variable udata_section_name to
7245 override default uninitialized data segment definition for
7246 devices only with SHAREBANK memory (reported from Erik Epetrich)
7247 * (pic14emitOverlay): modified to emit a commented overlay segment
7248 directive when no overlay data exist
7249 * (picglue): modified to emit uninitialized data segment
7250 according to udata_section_name

7255 arguments via -W option
7256 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7257 object file from '.rel' to '.o' in port->linker structure,
7258 changed size of fptr from 2 to 3 in port structure
7260 2004-01-07 Borut Razem <borut.razem AT siol.net>
7262 * support/scripts/sdcc.nsi: update PATH
7263 * support/scripts/sdcc.ico: craeted
7265 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7268 * doc/Makefile: fix install
7270 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7272 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7274 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7276 include information about variables allocated to the overlay
7279 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7281 * as/mcs51/lkmain.c: Help about -Y option

7291 LEFT_OP (left shift)
7293 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7295 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7296 (default behaviour).
7298 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7300 A python script to validate compiler diagnostic messages. It can be
7301 used to verify that sdcc complains about bad c source code and
7302 gives a good location of the error.
7303 * support/valdiag/Makefile,
7304 * support/valdiag/valdiag.py,
7305 * support/valdiag/tests/*
7307 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7309 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7318 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7320 * src/common.h: added ifndef/define/endif macros
7321 around the header file.
7322 Bug reported from Jesus Calvino-Fraga
7324 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7326 * sdcc.spec: updated
7327 * device/include/Makefile.in: don't install CVS directories
7328 * device/lib/Makefile.in: added removal of CVS directories after install
7329 * doc/Makefile: fixed install, added local_icons
7330 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7331 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7332 * src/ds390/gen.c (genRightShift): fixed bug #870788
7333 * src/SDCCast.c (decorateType): fixed bug #870781
7335 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7337 PIC16 port related changes:
7338 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7339 added variable stackPos,
7341 * gen.c: genCall, assignResultValue: added support for
7342 pushing/retrieving function parameters to/from stack,
7343 genFunction,genEndFunction: setup stack frame for the
7345 genAddrOf: will be changed according to bug 863624
7347 * added files genutils.c and genutils.h which contain gen*
7348 debugged and optimised functions extracted from gen.c
7350 * glue.c: added variable 'externs' which holds extern symbols,
7351 pic16emitRegularMap: is modified to properly handle relocatable
7352 symbols under the new scheme,
7353 pic16createInterruptVect: is modified
7354 pic16printPublics: is modified to emit 'global' assembler directives,
7355 added pic16_printExterns to print extern symbols,
7356 pic16glue: initializes stack/frame pointer in the beginning of
7357 the assembly output. Temporary hack, will be corrected later,
7358 because gplink yet does not support stack and SDCC does not
7359 yet support a type of crt0.o object to create the final binary.
7361 * Removed many lines that contain 8051 legacy code.
7362 * The code is finally placed under a 'code' directive.
7363 * Added port specific options.
7365 * _process_pragma: simplified since now we do not need *special*
7366 include file to define SFR registers. But a separate header
7367 will be needed. This will be developed later.
7368 * _pic16_parseOptions: added, parses port specific options:
7369 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7370 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7371 --preplace-udata-with=
7373 * _pic16_setDefaultOptions: modified to initialize section names,
7374 but hack is temporarly out of order since it needs improvement.
7375 * _pic16_genAssemblerPreamble: configuration words are emitted by
7376 their address instead of their name. This part is incomplete and
7377 supports only the 18Fxx2 devices. Other devices will emit an error
7378 during assembly since they do not contain the same set of config
7380 * _pic16_genIVT: is modified,
7382 * pcode.c: added definitions for some hardware registers that are needed
7384 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7385 All PCI entries are updated. Now LFSR is supported.
7386 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7387 * added pic16_newpCodeOpLit2 to support instructions with
7388 two literal arguments
7389 * pic16_pCode2str: corrected code that emits assembler instructions
7390 with two literal operands and those that have an access bit modifier
7391 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7392 this fixes a bug which caused some labels to be lost, when an
7393 assembler directive was added, i.e. banksel,
7394 * pic16_FixRegisterBanking: improved logic that causes the insertion
7396 * InlineFunction: functions that are called once, are not any more
7397 inlined. This can be a port option in the future,
7399 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7401 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7402 hold the corresponding uninitialized symbols,
7403 * pic16_allocProcessorRegister: registers have explicit marked the
7405 * pic16_allocInternalRegister: registers are explicit marked as
7407 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7408 processing list, so bit registers were lost,
7411 * ralloc.h: added field 'accessBank' and original symbol operand
7412 in register definition,
7413 * removed the field isMapped from register definition,
7415 ** Several functions have been removed from various sources:
7416 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7417 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7418 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7419 pic16_assignRelocatableRegisters
7421 ** others have been introduced:
7422 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7423 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7425 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7427 * support/scripts/inc2h.pl: changed definition of BIT_AT
7428 to emit 'sbit at' instead of 'bit at'. This was a request.
7430 PIC16 port related preliminary changes:
7431 * gen.c: prefixed function popRegFromString with
7432 pic16_ and all references to it corrected
7433 * pcode.c: all pic16_pc_* hardware registers prefixed
7434 with underscore (_),
7435 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7436 * ralloc.c: newReg(): when register is REG_SFR then
7437 set address to rIdx,
7438 pic16_allocProcessorRegister(): marks register wasUsed=0
7439 pic16_writeUsedRegs(): added a call to assign processor
7440 registers via pic16_assignFixedRegisters
7442 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7444 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7445 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7446 variables in unused register banks. Also the SSEG is placed
7447 wherever there is enough space for it, and IDATA can be anywhere
7448 in internal RAM. For now compile using -Wl-Y[stack_size].
7449 The mem file is different for this option as well, since it
7450 makes no sense of talking about DSEG lenght.
7452 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7454 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7455 in certain cases, e.g. when ROM assignment, patch provided
7456 from Albert den Haan.
7458 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8483 type for bits was changed. It resulted in bit variables becoming
8484 global, which is not permitted in PIC 14 assembly output.
8486 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8488 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8490 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8492 Z80 and MCS51 linkers complaint if a public symbol is defined
8493 in more than one library module:

8501 A few small changes that speed up the peephole optimizer.
8505 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8507 Try to make the peephole optimizer smarter by maintaining
8508 an association between the assembly source code and the
8509 iCodes that originated them. Put this information to use
8510 with a new peephole rule condition "notVolatile" so that
8511 the rules can be aggressive yet still safe.
8516 * src/mcs51/peeph.def
8518 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8522 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8523 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8524 if the left or right operand symbols have the accuse flag set.
8526 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8528 Changed the type of the result of the ! (NOT) operator to char;
8529 previously it returned the same type as the source. This allows
8530 us to eliminate all the genFloatNot functions (all of its target
8531 implementations were very buggy) since !float can use the same
8534 * src/SDCCicode.c (ast2iCode): ! returns char

8543 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8544 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8545 during interrupts. Ensure WSAVE is located at a shared bank address.
8546 2. Fixed page selection in some places
8547 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8548 the registers name strings.
8549 4. Fixed "signed / unsigned compare" compiler warnings.
8550 5. The PIC port manages its own allocation of the general purpose
8551 registers, but makes no attempt to reuse them. As a result when
8552 compiling it soon runs out of general purpose registers. Some
8553 additional code was added to the files pcode.c and device.c to walk
8554 through the function call tree and rename the registers so that they
8564 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8565 genPlus() & genMinus() when the result is the same as left or right

8571 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8573 Made bitfield a distinct type from bit so that bitfields
8574 convert as per ANSI C and bits retain their traditional
8575 boolean style behaviour. Implemented bitfield support in
8583 * src/ds390/gen.c: bit v bitfield split
8584 * src/z80/gen.c: New support for bitfields
8585 * support/regression/tests/bitfields.c: reenabled z80,
8588 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8590 Rules 246.x, 247.x relate to bitfields, the others speed up
8591 access to xdata mapped I/O devices.
8593 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8595 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8597 Cleaned up genPackBits and genUnpackBits and added two helper
8598 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8599 for literal assignments in genPackBits (thanks to Frieder for
8605 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8607 Fixed bug #748310 (pointer to function type mishandled when the
8608 function name is omitted). Also fixed a SIGSEGV when a function
8609 attribute (reentrant, etc) is used on a non-function or on a
8610 function but misplaced before the parameter list.
8612 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8614 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8637 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8639 Made the constant following the "interrupt" keyword optional. If
8640 omitted, the function will not automatically be given an entry
8641 in the interrupt vector table (similar to #pragma NOIV, but
8642 less syntacticly kludgy). The interrupt number is also now
8643 range checked. Also fixed a bug in the high order bit example

8661 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8662 be re-activated by defining REDUCE_LITERALS)
8663 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8664 unsigned, but are signed by default
8665 * src/SDCCval.c (constVal): rearranged
8666 * src/SDCCval.c (valMod): preliminary fix
8667 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9086 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9088 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9089 is in parts still quite out of date, I did changes as far as I felt makes sense
9090 for a non-native english speaker.
9091 Please feel free to add to the manual or to correct my changes.

9111 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9112 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9113 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9114 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9117 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9119 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9120 the regression tests I'm not brave enough to enable 245.b, 245.c
9121 * doc/sdccman.lyx: added latex preamble for hyperref package.
9122 Using pdflatex this will give you a hyperlinked pdf file with
9123 bookmarks. (prepend '%' before /usepackage if this breaks something)
9125 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9161 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9163 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9164 it can be defined with CFLAGS when running configure
9165 * src/SDCCmain.c: fixed compiling + linking with object files
9167 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9170 added --disable-pic16-port
9171 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9172 * src/SDCCmain.c: linkOptions is changed to set *,
9173 added if/endif conditional macros to remove options help
9174 messages from optionsTable when a port is not configured, added
9175 support for the PIc16 port in the ports table, when executing
9176 the compiler with no port specified on command line, a default
9177 port is selected with the new macro DEFAULT_PORT which is
9178 defined in port.h, in setDefaultOptions() linkOptions is removed
9179 from initialization assignment, since now it is a set,
9180 parseCmdLine uses setParseWithComma for linkOptions, in
9181 linkEdit() linkOptions are accessed with new function indexSet()
9182 which returns the i'th item of a set variable. See SDCCset.c, in
9183 linkEdit() when calling buildCmdLine(), added linkOptions as
9184 last argument. Now users can pass arguments to gplink via the
9185 -Wl option, main() uses pic16glue() to glue up pic16 programs
9186 * src/SDCCpeeph.c: various changes to support pic16

9197 * src/pic16/glue.c: commented out some error producing lines
9198 * src/pic16/main.c: __config directives are commented out to stop
9199 gpasm complaining and test the linkage with gplink, _linkCmd and
9200 _asmCmd changed to be more gplink and gpasm friendly
9201 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9202 produced an error when parsed, peep rule 12 is added to utilize
9203 movff, but it is commented out since the pCode does not support
9204 yet a command with 2 address arguments
9206 2003-05-18 <johan AT balder>
9208 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9209 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9210 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9228 on entry now. Add tbreak. Other enhancements and fixes for use
9231 2003-05-12 Borut Razem <borut.razem AT siol.net>
9233 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9235 2003-05-11 Borut Razem <borut.razem AT siol.net>
9237 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9238 the path of bin directory, so that PATH is the only env. variable, which has to be set
9239 in case of standard installation.
9240 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10269 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10271 * in \sdcc\as\mcs51\ changed these files in order to create an
10272 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10273 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10274 following files to include the previous two files: aslink.dsp,
10275 Makefile.aslink, Makefile.bcc, and Makefile.in.
10277 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10278 .adb instead of .cdb
10280 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10282 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10283 value from option --iram-size.
10285 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10287 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10290 2002-09-18 <wiml AT hhhh.org>
10292 * SDCClrange.h: exposed setFromRange() and setToRange()
10293 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10294 packRegsForAccUse() (bug 542397)
10295 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10296 multiple times and emitting the fetch operations more than once
10297 added aopGetUsesAcc() function to allow binary operators to
10298 fetch their operands in the correct order; made genMinus() emit
10299 compact code for X = LITERAL - Y
10301 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10302 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10303 sprintf() in line 1267.
10305 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10306 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10309 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10310 Changes to aslink (All the changes are marked with 'JCF'):
10312 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10315 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10316 area BSEG. Also moves, if possible, the DATA area down into the internal
10317 ram so more space is available.
10319 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10322 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10323 not bytes. Function summary() which creates a memory usage summary
10324 file with extension .mem. Reports of overlaping stack and small stack
10325 size. If the space for the stack is less than 16 bytes aslink trows a
10328 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10329 the 8051. Option 'y' for memory summary output file.
10331 Changes to sdcc (All the changes are marked with 'JCF'):
10333 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10335 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10336 overlaying area for it (uses RegBankUsed[4]).
10338 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10339 bank zero as used by default. By default aslink locates the stack
10340 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10341 the creation of the .mem file. Delegates the allocation of data area
10342 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10343 the begining of the stack area to aslink.
10345 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10346 glue() in SDCCglue.c creates an area for it.
10348 2002-09-03 Borut Razem <borut.razem AT siol.net>
10349 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10350 sdcc/src/pic/glue.c:
10351 introduced atexit() handler for teporay files removal in case of
10352 errors, assertions, ...
10354 2002-08-29 Borut Razem <borut.razem AT siol.net>
10355 * sdcc/support/cpp2/auto-host_vc_in.h:
10356 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10357 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10358 Maybe there is a similar problem with BORLANDC? It should be checked!
10360 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10361 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10362 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10363 was not executed, and the compiler (cl) launched a warning:
10364 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10366 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10367 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10369 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10377 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10378 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10379 - added Release configuration in VS projects
10380 - review of compiler an linker options
10381 - VC .exe files are generated in bin_vc directory, not to interfere
10382 with binaries generated from other projects (cygwin, mingw, bcc ...)
10384 * sdcc/src/yacc.dsp: added
10386 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10387 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10388 and insert the version number definitions from .version
10390 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10392 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10393 added - genarate auto-host.h using auto-host_vc_in.h as template
10396 removed from CVS, generated automatically
10398 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10399 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10401 2002-08-11 Borut Razem <borut.razem AT siol.net>
10402 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10404 2002-08-10 Borut Razem <borut.razem AT siol.net>
10405 * src/SDCCmain.c (main):
10406 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10407 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10408 The consequence was that some temporary files were not removed.
10411 unification of code in functions tempfilename() and tempfile():
10412 function tempnam() is defined in Visual Studio 6.0 and .NET
10414 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10416 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10417 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10418 - removed compiler command line option /WX: Treats all warnings as errors
10419 - update a list of source files, included into the project
10421 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10422 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10423 changed project type to Generic Project so that can be correcly converted to VS.NET project
10425 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10427 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10429 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10431 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10432 added return 0 statements after assert() to make compiler happy
10434 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10435 added newline in the def file to keep MSC compiler satisfied
10437 * sdcc/src/z80/gen.c:
10438 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10439 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10440 - solved MSC error in function aopDump()
10442 * sdcc_vc.h: define PREFIX as "\\sdcc"
10444 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10619 * sdcc/src/SDCCloop.c:
10620 Previous fix was not good. basic blocks that have "break" or "return" are
10621 not really partof a loop , but live ranges used in these blocks should
