359 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
361 Enabled VPATH feature: changed nearly all Makefiles (149 files).
362 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
364 One basic decision: e.g. src/clean.mk includes further files. In order
365 to make this work there are two solutions:
366 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
367 run configure on them. This way they can use
368 'include $(srcdir)/port-clean.mk'
369 - always include clean.mk by the Makefile at the same level. To avoid
370 that `make clean` tries to include and build Makefile.dep the
371 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
372 implemented, because now even `make uninstall` doesn't create
373 Makefile.in. clean.mk could be eliminated by pasting it in
376 * debugger/mcs51/Makefile.in: build own objects from library sources
377 (SLIB, SDCC) in current directory
379 * configure, configure.in: renamed --disable-device-lib-build in
380 --disable-device-lib; added --enable-doc, the required tools are
381 searched by configure; added result message; the toolchain for the
382 belonging ports are now only built, if the port is enabled.
384 * support/regression/*: all output is written in directory gen, because
385 the fwk and ports directories don't livet in the build tree using vpath
387 * doc/sdccman.lyx: renamed --disable-device-lib-build to
388 --disable-device-lib, added --enable-doc, added section VPATH
390 * sim/ucsim/configure.in,
391 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
392 z80 are enabled by default
394 2006-04-24 Raphael Neider <rneider AT web.de>
396 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
397 to config word, "pic14_"-prefixed some extern functions
398 (pic14_emitConfigWord): emit __config directive(s) if assignment to
399 config word has been found
400 * src/pic/device.h: added prototypes
401 * src/pic/pcode.c: added "pic14_"-prefix where needed

404 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
406 (pic14emitRegularMap): ignore config words,
407 (pic14createInterruptVect): moved generating __config directives away

418 fixes #1469504 and #1474602,
419 (pCodeRegOptimizeRegUsage): fixed typo in comment
421 2006-04-24 Borut Razem <borut.razem AT siol.net>
423 * device/examples/main8051.c: deleted - it was removed from CVS
424 24.mar.2000 and after that modified 18.feb.2001, so it reappered

426 * src/SDCCalloc.h: deleted - it was removed from CVS

684 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
687 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
689 * src/.version: increased version number to 2.5.5

691 linking is done manually in pic16 port's _linkEdit,
692 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
693 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

779 port->fun_prefix anymore (may change later),
780 (genFunction, genEndFunction): do not store/restore local registers for
781 _main (this should take care the --main-return command line option in
783 (genOr): removed some legacy pic-port instructions,
784 * src/pic16/genarith.c (genAddLit): re-enabled old code because
785 performing operations with SFR's causes data to be written more than
786 once to each SFR. Perhaps SFRs should be handled in special cases...
787 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
789 * src/pic16/main.c (_process_pragma): stack bound checking did not take
790 into account for stack starting position,
791 (struct OPTIONS pic16_optionsTable): added command line argument
792 --extended or -y for Extended Instruction Support,
793 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
794 (deassignLRs): *** perhaps the most important change, old 'for' code
795 (commented out for reference), didn't account for some registers which

3066 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3068 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3069 * src/z80/main.c (_keywords[]),
3070 * src/SDCCglobal.h (struct options),
3072 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3073 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3074 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3075 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3076 always available in leading double underscore form. The C99 support is
3077 mostly missing, but it's a start.
3078 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3079 reserved identifier "__data".
3081 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3127 2005-03-20 Borut Razem <borut.razem AT siol.net>
3129 * support/scripts/inc2h.pl: WIN32 port

3157 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3159 * device/lib/printf_large.c: removed inline assembly for portability and
3160 readability. Use printf_fast if speed or size are more important.
3161 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3162 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3164 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3166 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3167 prevent compiler warning
3169 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3171 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3172 moved to level 0 and declared as static. Also they are explicit
3173 placed in access bank. This was necessery because some times they
3174 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3175 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3176 optimizations. Currently only compare to unsigned char is implemented,
3177 * src/pic16/gen.c: added fReturnIdx array,
3178 * (struct resolvedIfx) is moved to gen.h and made public,
3179 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3180 * (aopForSym): added an optimization to directly store in stack of
3181 the operand of a SEND iCode,
3182 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3183 but as registers instead (AOP_REG) using the fReturnIdx array,
3184 * (pic16_freeAsmop): remove the freed register from the
3185 _G.sregsAlloc field,
3186 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3187 a compare of 'WREG',
3188 * (pic16_popGetTempRegCond): changed function prototype, now
3189 function takes also a bitVector argument v which holds the current
3190 set of registers that are allocated for stack access by aopForSym,
3191 registers allocated in aopForSym for accessing stack symbols are not
3192 any more part of the functions usedRegs field,
3193 * (genCall): some times aopOp is called for a stack variable to be
3194 send, aopForSym might perform the push, if this is true make sure
3195 that genCall doesn't push the variable twice by testing _G.resDirect,
3196 * (genFunction): changed testing for unspecified interrupt number
3197 from 256 to INTNO_UNSPEC,
3198 * modified selection scheme of frame pointer generation. Previously
3199 if function did use local registers a frame pointer was generated,
3200 now a frame pointer is generated only if function has arguments
3201 (that need PLUSW2 register access), or has stack arguments, or the
3202 compiler is not instructed to omit the frame pointer,
3203 * (genEndFunction): before restoring local registers that were saved
3204 in the function preamble, also restore the registers that *might*
3205 have been allocated for stack access,
3206 * (genRet): removed some old comments,
3207 * (genCmp, the active (RN's) version): added a call to the
3208 pic16_genCmp_special function to perform the compare with a more
3209 robust and optimized way,
3210 * (genInline): a feature has been added in inline code generation,
3211 which allows a wildcard variable substitution when writing inline
3212 assembly. Code is incomplete and experimental therefore undocumented,
3213 * (genCast): changed order of aopOp for result and right to allow
3214 aopForSym to directly load the result if possible,
3215 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3216 perform an optimized compare on some selected special occasions,
3217 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3218 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3219 generate an IVT any more,
3220 * src/pic16/main.c (pic16_optionsTable): added command line option
3222 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3223 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3225 * src/pic16/NOTES: Raphael Neider added in list of active developers
3226 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3227 jumptable_end to prevent bug #,
3228 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3229 inCond and outCond fields,
3230 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3231 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3232 turn off register spilling,
3233 * (packRegsForOneUse): synced with other ports' versions although it
3234 is not used currently,
3235 * (pic16_packRegisters): added an optimization while reading
3236 structure bitfields, some registers may be saved (malloc code is
3237 decreased by 80 bytes)
3239 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3241 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3242 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3243 this can be optimized more?
3245 2005-03-10 Raphael Neider <rneider AT web.de>
3247 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3248 genNearPointerGet): (hopefully) fixed access to bitfields via
3249 pointers (p->bitN = x; and x = p->bitN; failed)
3251 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3253 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3428 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3429 (sizeof(sectNames) changed to sizeof(sectName))
3430 Both patches fix segfaults under MinGW.

3436 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3437 of (byte sized) temporaries (assign them to WREG for now)
3438 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3439 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3440 this might fix SIGSEGVs on MinGW...
3441 * src/SDCCopt.c (killDeadCode): restored original behaviour
3442 (volatile operands might get thrown away though)
3444 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3446 * src/pic16/gen.c: fixed bug #1106975,

3900 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3902 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
3905 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
3907 * src/pic16/device.h,
3908 * src/pic16/genarith.c,
3911 * src/pic16/pcode.c: applied patches #1068154 and #1070213
3913 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3915 Large cummulative patch for pic16 port.
3916 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3917 to call when a stack overflow occurs,
3918 * (malloc.h): added CVS Id tag,
3919 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3921 * added libc directory. The current version of LibC contains string
3922 functions, ctype functions and macros and some functions of the
3923 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3924 be extensively tested in the future. Standard disclaimer here.
3925 Library is not automatically build yet. But one can build it by
3926 invoking 'make' inside the libc directory.
3927 * added ADC library under libio. Preliminary version yet.
3929 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3930 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3931 aopForRemat() now and not by pic16_aopOp(),
3932 * (pic16_popGetTempReg): removed warning messgae when allocating
3933 temporary registers, its a buggy feature and will be removed,
3934 * (pic16_popGet): set register instance field in AOP_CRY,
3935 * (pic16_outBitC): fixed for results in size greater than 1,
3936 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3937 * (pic16_storeForReturn): optimized return of 0,
3938 * (genCmp): experimental code for new genCmp which uses PIC18's
3939 special compare&skip instructions. Initial tests fail some times
3940 with variables grater than 1 byte in size, so new code is disabled,
3941 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3943 * (genCast): began a fix to optimize the casting of a bit to another
3944 bit, now assigning a bitfield to another bitfield will fail, sorry,
3945 * src/pic16/main.c: disabled the use of lr-support feature,
3946 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3947 * added some function prototypes, added function _debugf prototype,
3948 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3949 bits with offset (case PO_GPR_BIT),
3950 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3952 * (isBankInstruction): modified to return 0 for no banking instruction,
3953 and 1 for banking instruction,
3954 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3955 caused stop processing pCodes after a inline assembly block,
3956 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3957 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3958 registers when it shouldn't,
3959 * src/pic16/ralloc.c (allocReg): add preliminary support for
3960 supporting a limited set of temporary registers,
3962 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3964 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3965 genDataPointerSet): ensure assignments always copy in MSB to LSB
3967 (loadRegFromAop): recognize CLRH optimization,
3968 (genFunction): optimize RECEIVE iCodes in reentrant functions
3970 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3972 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3973 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3975 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

3986 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

6967 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6969 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6970 loaded with the linker search paths (-L arguments) and the libraries
6971 to be linked with the current source (-l arguments). Changes
6972 currently will affect only the pic16 port.
6973 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6974 include path the port specific paths and port specific libraries,
6975 * gplink command now contains the $3 argument,
6976 * src/pic16/device.h,
6977 * src/pic16/device.c,: structure PIC_device is made public and
6978 renamed to PIC16_device, the same for variable Pics which is renamed

6993 Documenting changes from previous commits.
6994 * configure.in (version 1.56),
6995 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6996 when generating output files to configure the pic16 library,
6997 but now I've commented it out, since gputils aren't installed in the
6998 SF compile farm, so library won't compile
7000 * device/lib/Makefile.in (version 1.56): initially I've added in
7001 target 'all' the prerequestive 'model-pic16' so it compiled the
7002 pic16 library, but now I've commented it out for the same reasons
7004 * added targets 'model-pic16' and 'objects-pic16' to compile the
7006 * added target 'port-specific-objects-pic16' to handle the
7007 generated libraries and copy them into the build/ directory
7008 * added target 'clean-intermediate-pic16' to clean intermediate
7009 files into pic16 directory
7010 * in target 'installdirs' added line to create directory pic16 in
7011 the installation path

7014 added lines to copy all header files to installation path,
7015 * in target 'installdirs' added line create directory for pic16
7016 headers in the installation path

7031 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7032 option so that it actually works. Made it specific to the z80, since
7033 the gbz80 doesn't have these kinds of I/O ports.
7035 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7037 * device/include/z180.h,

7061 via literal number. The symbol is placed in the corresponding
7062 position of the data ram
7063 * (pic16_dump_section): relocatable and absolute uninitialized
7064 data are now emitted in sorted order to reduce section naming,
7065 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7066 weren't marked as being in the access bank,
7068 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7070 Added portion of GNU PIC Library under the directory
7071 device/include/pic16 and device/lib/pic16. These files
7072 contain the declarations of SFRs for the PIC18Fxx2 devices.
7073 The directory is initialized via configure from toplevel.
7075 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7077 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7078 the spilllocations to be compared correctly

7103 all over. Telling LaTeX to be less strict with word spacing
7104 to better keep the right margin. Changed some notes about
7105 maintainance of the ports in section 3.2.1 - is it OK like this?
7107 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7144 UPPER for immediate operands,
7145 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7147 * src/pic16/peeph.def: all peepholes with movff are commented out,
7148 because there is a problem in the pcode peep optimizer,
7149 * src/pic16/ralloc.c: the register allocator can now reuse local
7150 function symbols for another function. This saves register usage.
7151 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7153 Added file src/pic16/NOTES with information about program writing on
7154 the current port version.

7183 gen51Code): more efficient parameter receive for --model-large
7186 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7189 * src/z80/main.c: added missed needLinkerScript flags (more than
7190 one port structure defined in these file)
7191 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7207 needLinkerScript flag
7209 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7210 * src/pic/glue.c: added variable udata_section_name to
7211 override default uninitialized data segment definition for
7212 devices only with SHAREBANK memory (reported from Erik Epetrich)
7213 * (pic14emitOverlay): modified to emit a commented overlay segment
7214 directive when no overlay data exist
7215 * (picglue): modified to emit uninitialized data segment
7216 according to udata_section_name

7226 2004-01-07 Borut Razem <borut.razem AT siol.net>
7228 * support/scripts/sdcc.nsi: update PATH
7229 * support/scripts/sdcc.ico: craeted

7236 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7238 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7240 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7242 include information about variables allocated to the overlay
7245 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7247 * as/mcs51/lkmain.c: Help about -Y option

7259 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7261 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7262 (default behaviour).
7264 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7266 A python script to validate compiler diagnostic messages. It can be
7267 used to verify that sdcc complains about bad c source code and
7268 gives a good location of the error.
7269 * support/valdiag/Makefile,
7270 * support/valdiag/valdiag.py,
7271 * support/valdiag/tests/*
7273 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7275 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7286 * src/common.h: added ifndef/define/endif macros
7287 around the header file.
7288 Bug reported from Jesus Calvino-Fraga
7290 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7292 * sdcc.spec: updated
7293 * device/include/Makefile.in: don't install CVS directories
7294 * device/lib/Makefile.in: added removal of CVS directories after install
7295 * doc/Makefile: fixed install, added local_icons
7296 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7297 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7298 * src/ds390/gen.c (genRightShift): fixed bug #870788
7299 * src/SDCCast.c (decorateType): fixed bug #870781
7301 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7303 PIC16 port related changes:
7304 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7305 added variable stackPos,
7307 * gen.c: genCall, assignResultValue: added support for
7308 pushing/retrieving function parameters to/from stack,
7309 genFunction,genEndFunction: setup stack frame for the
7311 genAddrOf: will be changed according to bug 863624
7313 * added files genutils.c and genutils.h which contain gen*
7314 debugged and optimised functions extracted from gen.c
7316 * glue.c: added variable 'externs' which holds extern symbols,
7317 pic16emitRegularMap: is modified to properly handle relocatable
7318 symbols under the new scheme,
7319 pic16createInterruptVect: is modified
7320 pic16printPublics: is modified to emit 'global' assembler directives,
7321 added pic16_printExterns to print extern symbols,
7322 pic16glue: initializes stack/frame pointer in the beginning of
7323 the assembly output. Temporary hack, will be corrected later,
7324 because gplink yet does not support stack and SDCC does not
7325 yet support a type of crt0.o object to create the final binary.
7327 * Removed many lines that contain 8051 legacy code.
7328 * The code is finally placed under a 'code' directive.
7329 * Added port specific options.
7331 * _process_pragma: simplified since now we do not need *special*
7332 include file to define SFR registers. But a separate header
7333 will be needed. This will be developed later.
7334 * _pic16_parseOptions: added, parses port specific options:
7335 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7336 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7337 --preplace-udata-with=
7339 * _pic16_setDefaultOptions: modified to initialize section names,
7340 but hack is temporarly out of order since it needs improvement.
7341 * _pic16_genAssemblerPreamble: configuration words are emitted by
7342 their address instead of their name. This part is incomplete and
7343 supports only the 18Fxx2 devices. Other devices will emit an error
7344 during assembly since they do not contain the same set of config
7346 * _pic16_genIVT: is modified,
7348 * pcode.c: added definitions for some hardware registers that are needed
7350 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7351 All PCI entries are updated. Now LFSR is supported.
7352 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7353 * added pic16_newpCodeOpLit2 to support instructions with
7354 two literal arguments
7355 * pic16_pCode2str: corrected code that emits assembler instructions
7356 with two literal operands and those that have an access bit modifier
7357 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7358 this fixes a bug which caused some labels to be lost, when an
7359 assembler directive was added, i.e. banksel,
7360 * pic16_FixRegisterBanking: improved logic that causes the insertion
7362 * InlineFunction: functions that are called once, are not any more
7363 inlined. This can be a port option in the future,
7365 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7367 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7368 hold the corresponding uninitialized symbols,
7369 * pic16_allocProcessorRegister: registers have explicit marked the
7371 * pic16_allocInternalRegister: registers are explicit marked as
7373 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7374 processing list, so bit registers were lost,
7377 * ralloc.h: added field 'accessBank' and original symbol operand
7378 in register definition,
7379 * removed the field isMapped from register definition,
7381 ** Several functions have been removed from various sources:
7382 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7383 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7384 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7385 pic16_assignRelocatableRegisters
7387 ** others have been introduced:
7388 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7389 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7391 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7393 * support/scripts/inc2h.pl: changed definition of BIT_AT
7394 to emit 'sbit at' instead of 'bit at'. This was a request.
7396 PIC16 port related preliminary changes:
7397 * gen.c: prefixed function popRegFromString with
7398 pic16_ and all references to it corrected
7399 * pcode.c: all pic16_pc_* hardware registers prefixed
7400 with underscore (_),
7401 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7402 * ralloc.c: newReg(): when register is REG_SFR then
7403 set address to rIdx,
7404 pic16_allocProcessorRegister(): marks register wasUsed=0
7405 pic16_writeUsedRegs(): added a call to assign processor
7406 registers via pic16_assignFixedRegisters
7408 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7410 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7411 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7412 variables in unused register banks. Also the SSEG is placed
7413 wherever there is enough space for it, and IDATA can be anywhere
7414 in internal RAM. For now compile using -Wl-Y[stack_size].
7415 The mem file is different for this option as well, since it
7416 makes no sense of talking about DSEG lenght.
7418 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7420 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7421 in certain cases, e.g. when ROM assignment, patch provided
7422 from Albert den Haan.
7424 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7977 not occur if the control variable is involved with a
7978 relational operator.

8467 A few small changes that speed up the peephole optimizer.
8471 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8473 Try to make the peephole optimizer smarter by maintaining
8474 an association between the assembly source code and the
8475 iCodes that originated them. Put this information to use
8476 with a new peephole rule condition "notVolatile" so that
8477 the rules can be aggressive yet still safe.
8482 * src/mcs51/peeph.def
8484 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8496 us to eliminate all the genFloatNot functions (all of its target
8497 implementations were very buggy) since !float can use the same

8509 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8510 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8511 during interrupts. Ensure WSAVE is located at a shared bank address.
8512 2. Fixed page selection in some places
8513 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8514 the registers name strings.
8515 4. Fixed "signed / unsigned compare" compiler warnings.
8516 5. The PIC port manages its own allocation of the general purpose
8517 registers, but makes no attempt to reuse them. As a result when
8518 compiling it soon runs out of general purpose registers. Some
8519 additional code was added to the files pcode.c and device.c to walk
8520 through the function call tree and rename the registers so that they
8530 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8537 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8539 Made bitfield a distinct type from bit so that bitfields
8540 convert as per ANSI C and bits retain their traditional
8541 boolean style behaviour. Implemented bitfield support in
8549 * src/ds390/gen.c: bit v bitfield split
8550 * src/z80/gen.c: New support for bitfields

8554 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8556 Rules 246.x, 247.x relate to bitfields, the others speed up
8557 access to xdata mapped I/O devices.
8559 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8561 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8563 Cleaned up genPackBits and genUnpackBits and added two helper
8564 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8565 for literal assignments in genPackBits (thanks to Frieder for
8571 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8573 Fixed bug #748310 (pointer to function type mishandled when the
8574 function name is omitted). Also fixed a SIGSEGV when a function
8575 attribute (reentrant, etc) is used on a non-function or on a
8576 function but misplaced before the parameter list.

8605 Made the constant following the "interrupt" keyword optional. If
8606 omitted, the function will not automatically be given an entry
8607 in the interrupt vector table (similar to #pragma NOIV, but
8608 less syntacticly kludgy). The interrupt number is also now
8609 range checked. Also fixed a bug in the high order bit example

9085 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9086 the regression tests I'm not brave enough to enable 245.b, 245.c
9087 * doc/sdccman.lyx: added latex preamble for hyperref package.
9088 Using pdflatex this will give you a hyperlinked pdf file with

9136 added --disable-pic16-port
9137 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9138 * src/SDCCmain.c: linkOptions is changed to set *,
9139 added if/endif conditional macros to remove options help
9140 messages from optionsTable when a port is not configured, added
9141 support for the PIc16 port in the ports table, when executing
9142 the compiler with no port specified on command line, a default
9143 port is selected with the new macro DEFAULT_PORT which is
9144 defined in port.h, in setDefaultOptions() linkOptions is removed
9145 from initialization assignment, since now it is a set,
9146 parseCmdLine uses setParseWithComma for linkOptions, in
9147 linkEdit() linkOptions are accessed with new function indexSet()
9148 which returns the i'th item of a set variable. See SDCCset.c, in
9149 linkEdit() when calling buildCmdLine(), added linkOptions as
9150 last argument. Now users can pass arguments to gplink via the
9151 -Wl option, main() uses pic16glue() to glue up pic16 programs

9163 * src/pic16/glue.c: commented out some error producing lines
9164 * src/pic16/main.c: __config directives are commented out to stop
9165 gpasm complaining and test the linkage with gplink, _linkCmd and
9166 _asmCmd changed to be more gplink and gpasm friendly
9167 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9168 produced an error when parsed, peep rule 12 is added to utilize
9169 movff, but it is commented out since the pCode does not support
9170 yet a command with 2 address arguments
9172 2003-05-18 <johan AT balder>
9174 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9199 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9201 2003-05-11 Borut Razem <borut.razem AT siol.net>
9203 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9204 the path of bin directory, so that PATH is the only env. variable, which has to be set
9205 in case of standard installation.
9206 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10222 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10223 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10230 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10232 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10233 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10235 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10237 * in \sdcc\as\mcs51\ changed these files in order to create an
10238 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10239 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10240 following files to include the previous two files: aslink.dsp,
10241 Makefile.aslink, Makefile.bcc, and Makefile.in.
10243 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10244 .adb instead of .cdb
10246 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10248 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10249 value from option --iram-size.
10251 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10253 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10256 2002-09-18 <wiml AT hhhh.org>
10258 * SDCClrange.h: exposed setFromRange() and setToRange()
10259 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10260 packRegsForAccUse() (bug 542397)
10261 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10262 multiple times and emitting the fetch operations more than once
10263 added aopGetUsesAcc() function to allow binary operators to
10264 fetch their operands in the correct order; made genMinus() emit
10265 compact code for X = LITERAL - Y
10267 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10268 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10269 sprintf() in line 1267.
10271 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10272 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10275 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10276 Changes to aslink (All the changes are marked with 'JCF'):
10278 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10281 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10282 area BSEG. Also moves, if possible, the DATA area down into the internal
10283 ram so more space is available.
10285 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10288 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10289 not bytes. Function summary() which creates a memory usage summary
10290 file with extension .mem. Reports of overlaping stack and small stack
10291 size. If the space for the stack is less than 16 bytes aslink trows a
10294 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10295 the 8051. Option 'y' for memory summary output file.
10297 Changes to sdcc (All the changes are marked with 'JCF'):
10299 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10301 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10302 overlaying area for it (uses RegBankUsed[4]).
10304 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10305 bank zero as used by default. By default aslink locates the stack
10306 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10307 the creation of the .mem file. Delegates the allocation of data area
10308 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10309 the begining of the stack area to aslink.
10311 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10312 glue() in SDCCglue.c creates an area for it.
10314 2002-09-03 Borut Razem <borut.razem AT siol.net>
10315 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10316 sdcc/src/pic/glue.c:
10317 introduced atexit() handler for teporay files removal in case of
10318 errors, assertions, ...
10320 2002-08-29 Borut Razem <borut.razem AT siol.net>
10321 * sdcc/support/cpp2/auto-host_vc_in.h:
10322 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10323 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10324 Maybe there is a similar problem with BORLANDC? It should be checked!
10326 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10327 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10328 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10329 was not executed, and the compiler (cl) launched a warning:
10330 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10332 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10333 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10335 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10336 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10338 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10339 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10340 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10341 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10342 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10343 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10344 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10345 - added Release configuration in VS projects
10346 - review of compiler an linker options
10347 - VC .exe files are generated in bin_vc directory, not to interfere
10348 with binaries generated from other projects (cygwin, mingw, bcc ...)
10350 * sdcc/src/yacc.dsp: added
10352 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10353 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10354 and insert the version number definitions from .version
10356 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10358 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10359 added - genarate auto-host.h using auto-host_vc_in.h as template
10362 removed from CVS, generated automatically
10364 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10365 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10367 2002-08-11 Borut Razem <borut.razem AT siol.net>
10368 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10370 2002-08-10 Borut Razem <borut.razem AT siol.net>
10371 * src/SDCCmain.c (main):
10372 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10373 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10374 The consequence was that some temporary files were not removed.
10377 unification of code in functions tempfilename() and tempfile():

10586 Previous fix was not good. basic blocks that have "break" or "return" are
10587 not really partof a loop , but live ranges used in these blocks should
