382 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
384 Enabled VPATH feature: changed nearly all Makefiles (149 files).
385 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
387 One basic decision: e.g. src/clean.mk includes further files. In order
388 to make this work there are two solutions:
389 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
390 run configure on them. This way they can use
391 'include $(srcdir)/port-clean.mk'
392 - always include clean.mk by the Makefile at the same level. To avoid
393 that `make clean` tries to include and build Makefile.dep the
394 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
395 implemented, because now even `make uninstall` doesn't create
396 Makefile.in. clean.mk could be eliminated by pasting it in
399 * debugger/mcs51/Makefile.in: build own objects from library sources
400 (SLIB, SDCC) in current directory
402 * configure, configure.in: renamed --disable-device-lib-build in
403 --disable-device-lib; added --enable-doc, the required tools are
404 searched by configure; added result message; the toolchain for the
405 belonging ports are now only built, if the port is enabled.
407 * support/regression/*: all output is written in directory gen, because
408 the fwk and ports directories don't livet in the build tree using vpath
410 * doc/sdccman.lyx: renamed --disable-device-lib-build to
411 --disable-device-lib, added --enable-doc, added section VPATH
413 * sim/ucsim/configure.in,
414 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
415 z80 are enabled by default
417 2006-04-24 Raphael Neider <rneider AT web.de>
419 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
420 to config word, "pic14_"-prefixed some extern functions
421 (pic14_emitConfigWord): emit __config directive(s) if assignment to
422 config word has been found
423 * src/pic/device.h: added prototypes
424 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

441 fixes #1469504 and #1474602,
442 (pCodeRegOptimizeRegUsage): fixed typo in comment
444 2006-04-24 Borut Razem <borut.razem AT siol.net>
446 * device/examples/main8051.c: deleted - it was removed from CVS
447 24.mar.2000 and after that modified 18.feb.2001, so it reappered
448 after the transition to Subversion
449 * src/SDCCalloc.h: deleted - it was removed from CVS
450 3.feb.2001 and after that modified 18.feb.2001, so it reappered
451 after the transition to Subversion

702 2006-03-16 Raphael Neider <rneider AT web.de>
704 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
705 the left operand is shorter than the result (c* = lit-c* + int),
707 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
710 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
712 * src/.version: increased version number to 2.5.5
713 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
714 linking is done manually in pic16 port's _linkEdit,
715 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
716 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

718 allocate asmop as AOP_ACC,
719 (aopForRemat): added parameter 'bool result' in function declaration,

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

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

3089 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3091 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3095 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3096 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3097 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3098 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3099 always available in leading double underscore form. The C99 support is
3100 mostly missing, but it's a start.
3101 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3102 reserved identifier "__data".
3104 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3150 2005-03-20 Borut Razem <borut.razem AT siol.net>
3152 * support/scripts/inc2h.pl: WIN32 port

3180 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3182 * device/lib/printf_large.c: removed inline assembly for portability and
3183 readability. Use printf_fast if speed or size are more important.
3184 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3185 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3187 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3189 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3190 prevent compiler warning
3192 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3194 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3195 moved to level 0 and declared as static. Also they are explicit
3196 placed in access bank. This was necessery because some times they
3197 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3198 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3199 optimizations. Currently only compare to unsigned char is implemented,
3200 * src/pic16/gen.c: added fReturnIdx array,
3201 * (struct resolvedIfx) is moved to gen.h and made public,
3202 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3203 * (aopForSym): added an optimization to directly store in stack of
3204 the operand of a SEND iCode,
3205 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3206 but as registers instead (AOP_REG) using the fReturnIdx array,
3207 * (pic16_freeAsmop): remove the freed register from the
3208 _G.sregsAlloc field,
3209 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3210 a compare of 'WREG',
3211 * (pic16_popGetTempRegCond): changed function prototype, now
3212 function takes also a bitVector argument v which holds the current
3213 set of registers that are allocated for stack access by aopForSym,
3214 registers allocated in aopForSym for accessing stack symbols are not
3215 any more part of the functions usedRegs field,
3216 * (genCall): some times aopOp is called for a stack variable to be
3217 send, aopForSym might perform the push, if this is true make sure
3218 that genCall doesn't push the variable twice by testing _G.resDirect,
3219 * (genFunction): changed testing for unspecified interrupt number
3220 from 256 to INTNO_UNSPEC,
3221 * modified selection scheme of frame pointer generation. Previously
3222 if function did use local registers a frame pointer was generated,
3223 now a frame pointer is generated only if function has arguments
3224 (that need PLUSW2 register access), or has stack arguments, or the
3225 compiler is not instructed to omit the frame pointer,
3226 * (genEndFunction): before restoring local registers that were saved
3227 in the function preamble, also restore the registers that *might*
3228 have been allocated for stack access,
3229 * (genRet): removed some old comments,
3230 * (genCmp, the active (RN's) version): added a call to the
3231 pic16_genCmp_special function to perform the compare with a more
3232 robust and optimized way,
3233 * (genInline): a feature has been added in inline code generation,
3234 which allows a wildcard variable substitution when writing inline
3235 assembly. Code is incomplete and experimental therefore undocumented,
3236 * (genCast): changed order of aopOp for result and right to allow
3237 aopForSym to directly load the result if possible,
3238 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3239 perform an optimized compare on some selected special occasions,
3240 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3241 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3242 generate an IVT any more,
3243 * src/pic16/main.c (pic16_optionsTable): added command line option
3245 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3246 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3248 * src/pic16/NOTES: Raphael Neider added in list of active developers
3249 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3250 jumptable_end to prevent bug #,
3251 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3252 inCond and outCond fields,
3253 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3254 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3255 turn off register spilling,
3256 * (packRegsForOneUse): synced with other ports' versions although it
3257 is not used currently,
3258 * (pic16_packRegisters): added an optimization while reading
3259 structure bitfields, some registers may be saved (malloc code is
3260 decreased by 80 bytes)
3262 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3264 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3265 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3266 this can be optimized more?
3268 2005-03-10 Raphael Neider <rneider AT web.de>
3270 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3271 genNearPointerGet): (hopefully) fixed access to bitfields via
3272 pointers (p->bitN = x; and x = p->bitN; failed)
3274 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3276 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3315 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3317 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3318 to keep the correct label reference count when adding/removing references
3319 to labels. A peephole file using this is appended to patch #1144962.
3321 2005-02-14 Raphael Neider <rneider AT web.de>

3451 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3452 (sizeof(sectNames) changed to sizeof(sectName))
3453 Both patches fix segfaults under MinGW.
3455 2005-01-23 Raphael Neider <rneider AT web.de>

3458 Safe_[mc]?alloc()'ed variables
3459 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3460 of (byte sized) temporaries (assign them to WREG for now)
3461 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3462 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3463 this might fix SIGSEGVs on MinGW...
3464 * src/SDCCopt.c (killDeadCode): restored original behaviour
3465 (volatile operands might get thrown away though)
3467 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3469 * src/pic16/gen.c: fixed bug #1106975,

3904 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3906 Adding support for replacing ljmps with sjmps in jumptables
3907 generated for switch statements. For now you need to set the
3908 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3909 Now 4 algorithms for mcs51 jumptable generation are used:
3910 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3911 addresses loaded pc-relative for up to 112 cases and stack-pushing
3912 target addresses loaded with offset from dptr for up to 256 cases.
3914 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3915 * src/mcs51/main.c: adapted constants for switch table generation
3916 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3936 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3938 Large cummulative patch for pic16 port.
3939 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3940 to call when a stack overflow occurs,
3941 * (malloc.h): added CVS Id tag,
3942 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3944 * added libc directory. The current version of LibC contains string
3945 functions, ctype functions and macros and some functions of the
3946 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3947 be extensively tested in the future. Standard disclaimer here.
3948 Library is not automatically build yet. But one can build it by
3949 invoking 'make' inside the libc directory.
3950 * added ADC library under libio. Preliminary version yet.
3952 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3953 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3954 aopForRemat() now and not by pic16_aopOp(),

3956 temporary registers, its a buggy feature and will be removed,
3957 * (pic16_popGet): set register instance field in AOP_CRY,
3958 * (pic16_outBitC): fixed for results in size greater than 1,
3959 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3960 * (pic16_storeForReturn): optimized return of 0,
3961 * (genCmp): experimental code for new genCmp which uses PIC18's
3962 special compare&skip instructions. Initial tests fail some times
3963 with variables grater than 1 byte in size, so new code is disabled,
3964 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3966 * (genCast): began a fix to optimize the casting of a bit to another
3967 bit, now assigning a bitfield to another bitfield will fail, sorry,
3968 * src/pic16/main.c: disabled the use of lr-support feature,
3969 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3970 * added some function prototypes, added function _debugf prototype,
3971 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3972 bits with offset (case PO_GPR_BIT),
3973 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3975 * (isBankInstruction): modified to return 0 for no banking instruction,
3976 and 1 for banking instruction,
3977 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3978 caused stop processing pCodes after a inline assembly block,
3979 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3980 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3981 registers when it shouldn't,
3982 * src/pic16/ralloc.c (allocReg): add preliminary support for
3983 supporting a limited set of temporary registers,
3985 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3987 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3988 genDataPointerSet): ensure assignments always copy in MSB to LSB
3990 (loadRegFromAop): recognize CLRH optimization,
3991 (genFunction): optimize RECEIVE iCodes in reentrant functions
3993 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3995 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3996 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3998 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4007 instead of sjmp to ret
4008 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4009 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4011 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6993 loaded with the linker search paths (-L arguments) and the libraries
6994 to be linked with the current source (-l arguments). Changes
6995 currently will affect only the pic16 port.
6996 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6997 include path the port specific paths and port specific libraries,
6998 * gplink command now contains the $3 argument,
6999 * src/pic16/device.h,
7000 * src/pic16/device.c,: structure PIC_device is made public and
7001 renamed to PIC16_device, the same for variable Pics which is renamed
7002 to Pics16. Updated all references to them.
7003 * src/pic16/glue.c (pic16glue): corrected bug with code
7004 initialization which bypassed the variable initializations block.
7006 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7007 COMPILE_FLAGS and added the --nostdinc option
7009 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7011 * device/include/mc68hc908jb8.h: Register defs for another member

7014 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7016 Documenting changes from previous commits.
7017 * configure.in (version 1.56),
7018 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7019 when generating output files to configure the pic16 library,
7020 but now I've commented it out, since gputils aren't installed in the
7021 SF compile farm, so library won't compile
7023 * device/lib/Makefile.in (version 1.56): initially I've added in
7024 target 'all' the prerequestive 'model-pic16' so it compiled the
7025 pic16 library, but now I've commented it out for the same reasons
7027 * added targets 'model-pic16' and 'objects-pic16' to compile the
7029 * added target 'port-specific-objects-pic16' to handle the
7030 generated libraries and copy them into the build/ directory
7031 * added target 'clean-intermediate-pic16' to clean intermediate
7032 files into pic16 directory
7033 * in target 'installdirs' added line to create directory pic16 in
7034 the installation path
7036 * device/include/Makefile.in (version 1.11): in target 'install'
7037 added lines to copy all header files to installation path,
7038 * in target 'installdirs' added line create directory for pic16
7039 headers in the installation path

7054 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7055 option so that it actually works. Made it specific to the z80, since
7056 the gbz80 doesn't have these kinds of I/O ports.
7058 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7060 * device/include/z180.h,

7073 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7075 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7076 changed interrupt vector table generation to only emit declared vectors.
7077 * device/include/Makefile.in: added missing backslash
7078 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

7082 Mainly changes to support compilation of the device libraries
7083 * src/pic16/device.c: stack is allocated via symbol and not
7084 via literal number. The symbol is placed in the corresponding
7085 position of the data ram
7086 * (pic16_dump_section): relocatable and absolute uninitialized
7087 data are now emitted in sorted order to reduce section naming,
7088 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7089 weren't marked as being in the access bank,
7091 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7093 Added portion of GNU PIC Library under the directory
7094 device/include/pic16 and device/lib/pic16. These files
7095 contain the declarations of SFRs for the PIC18Fxx2 devices.
7096 The directory is initialized via configure from toplevel.
7098 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7100 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7101 the spilllocations to be compared correctly
7103 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7105 * src/SDCCast.c (decorateType): fixed bug introduced today
7107 2004-01-12 Borut Razem <borut.razem AT siol.net>

7125 * doc/sdccman.lyx: Moved and added some sections, small changes
7126 all over. Telling LaTeX to be less strict with word spacing
7127 to better keep the right margin. Changed some notes about
7128 maintainance of the ports in section 3.2.1 - is it OK like this?
7130 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7167 UPPER for immediate operands,
7168 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7170 * src/pic16/peeph.def: all peepholes with movff are commented out,
7171 because there is a problem in the pcode peep optimizer,
7172 * src/pic16/ralloc.c: the register allocator can now reuse local
7173 function symbols for another function. This saves register usage.
7174 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7176 Added file src/pic16/NOTES with information about program writing on
7177 the current port version.

7186 * src/SDCCmain.c : fixed #872250: -l command line defined library
7187 files are scanned before standard library files
7189 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7206 gen51Code): more efficient parameter receive for --model-large
7209 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7212 * src/z80/main.c: added missed needLinkerScript flags (more than
7213 one port structure defined in these file)
7214 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7230 needLinkerScript flag
7232 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7233 * src/pic/glue.c: added variable udata_section_name to
7234 override default uninitialized data segment definition for
7235 devices only with SHAREBANK memory (reported from Erik Epetrich)
7236 * (pic14emitOverlay): modified to emit a commented overlay segment
7237 directive when no overlay data exist
7238 * (picglue): modified to emit uninitialized data segment
7239 according to udata_section_name

7244 arguments via -W option
7245 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7246 object file from '.rel' to '.o' in port->linker structure,

7249 2004-01-07 Borut Razem <borut.razem AT siol.net>
7251 * support/scripts/sdcc.nsi: update PATH
7252 * support/scripts/sdcc.ico: craeted
7254 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7257 * doc/Makefile: fix install
7259 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7261 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7263 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7265 include information about variables allocated to the overlay
7268 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7270 * as/mcs51/lkmain.c: Help about -Y option

7282 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7284 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7285 (default behaviour).
7287 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7289 A python script to validate compiler diagnostic messages. It can be
7290 used to verify that sdcc complains about bad c source code and
7291 gives a good location of the error.
7292 * support/valdiag/Makefile,
7293 * support/valdiag/valdiag.py,
7294 * support/valdiag/tests/*
7296 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7309 * src/common.h: added ifndef/define/endif macros
7310 around the header file.
7311 Bug reported from Jesus Calvino-Fraga
7313 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7315 * sdcc.spec: updated
7316 * device/include/Makefile.in: don't install CVS directories
7317 * device/lib/Makefile.in: added removal of CVS directories after install
7318 * doc/Makefile: fixed install, added local_icons
7319 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7320 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7321 * src/ds390/gen.c (genRightShift): fixed bug #870788
7322 * src/SDCCast.c (decorateType): fixed bug #870781
7324 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7326 PIC16 port related changes:
7327 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7328 added variable stackPos,
7330 * gen.c: genCall, assignResultValue: added support for
7331 pushing/retrieving function parameters to/from stack,
7332 genFunction,genEndFunction: setup stack frame for the
7334 genAddrOf: will be changed according to bug 863624
7336 * added files genutils.c and genutils.h which contain gen*
7337 debugged and optimised functions extracted from gen.c
7339 * glue.c: added variable 'externs' which holds extern symbols,
7340 pic16emitRegularMap: is modified to properly handle relocatable
7341 symbols under the new scheme,
7342 pic16createInterruptVect: is modified
7343 pic16printPublics: is modified to emit 'global' assembler directives,
7344 added pic16_printExterns to print extern symbols,
7345 pic16glue: initializes stack/frame pointer in the beginning of
7346 the assembly output. Temporary hack, will be corrected later,
7347 because gplink yet does not support stack and SDCC does not
7348 yet support a type of crt0.o object to create the final binary.
7350 * Removed many lines that contain 8051 legacy code.
7351 * The code is finally placed under a 'code' directive.
7352 * Added port specific options.
7354 * _process_pragma: simplified since now we do not need *special*
7355 include file to define SFR registers. But a separate header
7356 will be needed. This will be developed later.
7357 * _pic16_parseOptions: added, parses port specific options:
7358 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7359 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7360 --preplace-udata-with=
7362 * _pic16_setDefaultOptions: modified to initialize section names,
7363 but hack is temporarly out of order since it needs improvement.
7364 * _pic16_genAssemblerPreamble: configuration words are emitted by
7365 their address instead of their name. This part is incomplete and
7366 supports only the 18Fxx2 devices. Other devices will emit an error
7367 during assembly since they do not contain the same set of config
7369 * _pic16_genIVT: is modified,
7371 * pcode.c: added definitions for some hardware registers that are needed
7373 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7374 All PCI entries are updated. Now LFSR is supported.
7375 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7376 * added pic16_newpCodeOpLit2 to support instructions with
7377 two literal arguments
7378 * pic16_pCode2str: corrected code that emits assembler instructions
7379 with two literal operands and those that have an access bit modifier
7380 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7381 this fixes a bug which caused some labels to be lost, when an
7382 assembler directive was added, i.e. banksel,
7383 * pic16_FixRegisterBanking: improved logic that causes the insertion
7385 * InlineFunction: functions that are called once, are not any more
7386 inlined. This can be a port option in the future,
7388 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7390 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7391 hold the corresponding uninitialized symbols,
7392 * pic16_allocProcessorRegister: registers have explicit marked the
7394 * pic16_allocInternalRegister: registers are explicit marked as
7396 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7397 processing list, so bit registers were lost,
7400 * ralloc.h: added field 'accessBank' and original symbol operand
7401 in register definition,
7402 * removed the field isMapped from register definition,
7404 ** Several functions have been removed from various sources:
7405 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7406 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7407 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7408 pic16_assignRelocatableRegisters
7410 ** others have been introduced:
7411 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7412 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7414 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7416 * support/scripts/inc2h.pl: changed definition of BIT_AT
7417 to emit 'sbit at' instead of 'bit at'. This was a request.
7419 PIC16 port related preliminary changes:
7420 * gen.c: prefixed function popRegFromString with
7421 pic16_ and all references to it corrected
7422 * pcode.c: all pic16_pc_* hardware registers prefixed
7423 with underscore (_),
7424 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7425 * ralloc.c: newReg(): when register is REG_SFR then
7426 set address to rIdx,
7427 pic16_allocProcessorRegister(): marks register wasUsed=0
7428 pic16_writeUsedRegs(): added a call to assign processor
7429 registers via pic16_assignFixedRegisters
7431 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7433 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7434 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7435 variables in unused register banks. Also the SSEG is placed
7436 wherever there is enough space for it, and IDATA can be anywhere
7437 in internal RAM. For now compile using -Wl-Y[stack_size].
7438 The mem file is different for this option as well, since it
7439 makes no sense of talking about DSEG lenght.
7441 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7443 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7444 in certain cases, e.g. when ROM assignment, patch provided
7445 from Albert den Haan.
7447 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8490 A few small changes that speed up the peephole optimizer.
8494 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8496 Try to make the peephole optimizer smarter by maintaining
8497 an association between the assembly source code and the
8498 iCodes that originated them. Put this information to use
8499 with a new peephole rule condition "notVolatile" so that
8500 the rules can be aggressive yet still safe.
8505 * src/mcs51/peeph.def
8507 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8511 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8512 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8513 if the left or right operand symbols have the accuse flag set.
8515 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8517 Changed the type of the result of the ! (NOT) operator to char;
8518 previously it returned the same type as the source. This allows
8519 us to eliminate all the genFloatNot functions (all of its target
8520 implementations were very buggy) since !float can use the same
8523 * src/SDCCicode.c (ast2iCode): ! returns char

8532 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8533 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8534 during interrupts. Ensure WSAVE is located at a shared bank address.
8535 2. Fixed page selection in some places
8536 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8537 the registers name strings.
8538 4. Fixed "signed / unsigned compare" compiler warnings.
8539 5. The PIC port manages its own allocation of the general purpose
8540 registers, but makes no attempt to reuse them. As a result when
8541 compiling it soon runs out of general purpose registers. Some
8542 additional code was added to the files pcode.c and device.c to walk
8543 through the function call tree and rename the registers so that they
8553 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8554 genPlus() & genMinus() when the result is the same as left or right

8560 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8562 Made bitfield a distinct type from bit so that bitfields
8563 convert as per ANSI C and bits retain their traditional
8564 boolean style behaviour. Implemented bitfield support in
8572 * src/ds390/gen.c: bit v bitfield split
8573 * src/z80/gen.c: New support for bitfields
8574 * support/regression/tests/bitfields.c: reenabled z80,
8577 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8579 Rules 246.x, 247.x relate to bitfields, the others speed up
8580 access to xdata mapped I/O devices.
8582 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8584 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8586 Cleaned up genPackBits and genUnpackBits and added two helper
8587 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8588 for literal assignments in genPackBits (thanks to Frieder for
8594 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8596 Fixed bug #748310 (pointer to function type mishandled when the
8597 function name is omitted). Also fixed a SIGSEGV when a function
8598 attribute (reentrant, etc) is used on a non-function or on a
8599 function but misplaced before the parameter list.
8601 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8603 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8626 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8628 Made the constant following the "interrupt" keyword optional. If
8629 omitted, the function will not automatically be given an entry
8630 in the interrupt vector table (similar to #pragma NOIV, but
8631 less syntacticly kludgy). The interrupt number is also now
8632 range checked. Also fixed a bug in the high order bit example

9073 condition and ignore commands.
9075 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9077 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9078 is in parts still quite out of date, I did changes as far as I felt makes sense
9079 for a non-native english speaker.
9080 Please feel free to add to the manual or to correct my changes.
9081 * doc/Makefile: undid touching the date of intermediate tex files.
9083 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9102 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9103 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9106 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9108 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9109 the regression tests I'm not brave enough to enable 245.b, 245.c
9110 * doc/sdccman.lyx: added latex preamble for hyperref package.
9111 Using pdflatex this will give you a hyperlinked pdf file with
9112 bookmarks. (prepend '%' before /usepackage if this breaks something)
9114 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9150 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9152 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9153 it can be defined with CFLAGS when running configure
9154 * src/SDCCmain.c: fixed compiling + linking with object files
9156 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9158 * configure.in: configure for pic16 port,
9159 added --disable-pic16-port
9160 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9161 * src/SDCCmain.c: linkOptions is changed to set *,
9162 added if/endif conditional macros to remove options help
9163 messages from optionsTable when a port is not configured, added
9164 support for the PIc16 port in the ports table, when executing
9165 the compiler with no port specified on command line, a default
9166 port is selected with the new macro DEFAULT_PORT which is
9167 defined in port.h, in setDefaultOptions() linkOptions is removed
9168 from initialization assignment, since now it is a set,
9169 parseCmdLine uses setParseWithComma for linkOptions, in
9170 linkEdit() linkOptions are accessed with new function indexSet()
9171 which returns the i'th item of a set variable. See SDCCset.c, in
9172 linkEdit() when calling buildCmdLine(), added linkOptions as
9173 last argument. Now users can pass arguments to gplink via the
9174 -Wl option, main() uses pic16glue() to glue up pic16 programs
9175 * src/SDCCpeeph.c: various changes to support pic16
9176 * src/SDCCset.c: added function void *indexSet(set *, int) to

9182 added macro DEFAULT_PORT
9183 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9184 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9186 * src/pic16/glue.c: commented out some error producing lines
9187 * src/pic16/main.c: __config directives are commented out to stop
9188 gpasm complaining and test the linkage with gplink, _linkCmd and
9189 _asmCmd changed to be more gplink and gpasm friendly
9190 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9191 produced an error when parsed, peep rule 12 is added to utilize
9192 movff, but it is commented out since the pCode does not support
9193 yet a command with 2 address arguments
9195 2003-05-18 <johan AT balder>
9197 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9198 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9222 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9224 2003-05-11 Borut Razem <borut.razem AT siol.net>
9226 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9227 the path of bin directory, so that PATH is the only env. variable, which has to be set
9228 in case of standard installation.
9229 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10258 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10260 * in \sdcc\as\mcs51\ changed these files in order to create an
10261 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10262 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10263 following files to include the previous two files: aslink.dsp,
10264 Makefile.aslink, Makefile.bcc, and Makefile.in.
10266 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10267 .adb instead of .cdb
10269 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10271 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10272 value from option --iram-size.
10274 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10276 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10279 2002-09-18 <wiml AT hhhh.org>
10281 * SDCClrange.h: exposed setFromRange() and setToRange()
10282 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10283 packRegsForAccUse() (bug 542397)
10284 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10285 multiple times and emitting the fetch operations more than once
10286 added aopGetUsesAcc() function to allow binary operators to
10287 fetch their operands in the correct order; made genMinus() emit
10288 compact code for X = LITERAL - Y
10290 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10291 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10292 sprintf() in line 1267.
10294 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10295 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10298 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10299 Changes to aslink (All the changes are marked with 'JCF'):
10301 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10304 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10305 area BSEG. Also moves, if possible, the DATA area down into the internal
10306 ram so more space is available.
10308 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10311 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10312 not bytes. Function summary() which creates a memory usage summary
10313 file with extension .mem. Reports of overlaping stack and small stack
10314 size. If the space for the stack is less than 16 bytes aslink trows a
10317 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10318 the 8051. Option 'y' for memory summary output file.
10320 Changes to sdcc (All the changes are marked with 'JCF'):
10322 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10324 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10325 overlaying area for it (uses RegBankUsed[4]).
10327 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10328 bank zero as used by default. By default aslink locates the stack
10329 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10330 the creation of the .mem file. Delegates the allocation of data area
10331 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10332 the begining of the stack area to aslink.
10334 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10335 glue() in SDCCglue.c creates an area for it.
10337 2002-09-03 Borut Razem <borut.razem AT siol.net>
10338 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10339 sdcc/src/pic/glue.c:
10340 introduced atexit() handler for teporay files removal in case of
10341 errors, assertions, ...
10343 2002-08-29 Borut Razem <borut.razem AT siol.net>
10344 * sdcc/support/cpp2/auto-host_vc_in.h:
10345 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10346 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10347 Maybe there is a similar problem with BORLANDC? It should be checked!
10349 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10350 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10351 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10352 was not executed, and the compiler (cl) launched a warning:
10353 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10355 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10356 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10358 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10367 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10368 - added Release configuration in VS projects
10369 - review of compiler an linker options
10370 - VC .exe files are generated in bin_vc directory, not to interfere
10371 with binaries generated from other projects (cygwin, mingw, bcc ...)
10373 * sdcc/src/yacc.dsp: added
10375 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10376 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10377 and insert the version number definitions from .version
10379 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10381 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10391 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10393 2002-08-10 Borut Razem <borut.razem AT siol.net>
10394 * src/SDCCmain.c (main):
10395 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10396 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10397 The consequence was that some temporary files were not removed.
10400 unification of code in functions tempfilename() and tempfile():
10401 function tempnam() is defined in Visual Studio 6.0 and .NET
10403 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10405 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10406 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10407 - removed compiler command line option /WX: Treats all warnings as errors
10408 - update a list of source files, included into the project
10410 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10411 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10412 changed project type to Generic Project so that can be correcly converted to VS.NET project
10414 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10416 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10420 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10421 added return 0 statements after assert() to make compiler happy
10423 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10424 added newline in the def file to keep MSC compiler satisfied
10426 * sdcc/src/z80/gen.c:
10427 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10428 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10429 - solved MSC error in function aopDump()
10431 * sdcc_vc.h: define PREFIX as "\\sdcc"
10433 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10609 Previous fix was not good. basic blocks that have "break" or "return" are
10610 not really partof a loop , but live ranges used in these blocks should
