426 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
428 Enabled VPATH feature: changed nearly all Makefiles (149 files).
429 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
431 One basic decision: e.g. src/clean.mk includes further files. In order
432 to make this work there are two solutions:
433 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
434 run configure on them. This way they can use
435 'include $(srcdir)/port-clean.mk'
436 - always include clean.mk by the Makefile at the same level. To avoid
437 that `make clean` tries to include and build Makefile.dep the
438 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
439 implemented, because now even `make uninstall` doesn't create
440 Makefile.in. clean.mk could be eliminated by pasting it in
443 * debugger/mcs51/Makefile.in: build own objects from library sources
444 (SLIB, SDCC) in current directory
446 * configure, configure.in: renamed --disable-device-lib-build in
447 --disable-device-lib; added --enable-doc, the required tools are
448 searched by configure; added result message; the toolchain for the
449 belonging ports are now only built, if the port is enabled.
451 * support/regression/*: all output is written in directory gen, because
452 the fwk and ports directories don't livet in the build tree using vpath
454 * doc/sdccman.lyx: renamed --disable-device-lib-build to
455 --disable-device-lib, added --enable-doc, added section VPATH
457 * sim/ucsim/configure.in,
458 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
459 z80 are enabled by default
461 2006-04-24 Raphael Neider <rneider AT web.de>
463 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
464 to config word, "pic14_"-prefixed some extern functions
465 (pic14_emitConfigWord): emit __config directive(s) if assignment to
466 config word has been found
467 * src/pic/device.h: added prototypes
468 * src/pic/pcode.c: added "pic14_"-prefix where needed
469 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
471 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
473 (pic14emitRegularMap): ignore config words,
474 (pic14createInterruptVect): moved generating __config directives away
475 (picglue): have __config directives emitted
477 2006-04-24 Borut Razem <borut.razem AT siol.net>
479 * doc/Makefile: sync with nightly build makefile
481 2006-04-24 Raphael Neider <rneider AT web.de>

751 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
754 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
756 * src/.version: increased version number to 2.5.5
757 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
758 linking is done manually in pic16 port's _linkEdit,
759 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
760 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

840 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
841 which dumps before the function entry point a data byte which represents
842 the number of the local variables used by the specified function, added
843 'xinst' for initial support for Extended Instruction Support,
844 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
845 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
846 port->fun_prefix anymore (may change later),
847 (genFunction, genEndFunction): do not store/restore local registers for
848 _main (this should take care the --main-return command line option in
850 (genOr): removed some legacy pic-port instructions,
851 * src/pic16/genarith.c (genAddLit): re-enabled old code because
852 performing operations with SFR's causes data to be written more than
853 once to each SFR. Perhaps SFRs should be handled in special cases...
854 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
856 * src/pic16/main.c (_process_pragma): stack bound checking did not take
857 into account for stack starting position,
858 (struct OPTIONS pic16_optionsTable): added command line argument
859 --extended or -y for Extended Instruction Support,
860 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
861 (deassignLRs): *** perhaps the most important change, old 'for' code
862 (commented out for reference), didn't account for some registers which
863 were left marked 'not free' after a pointer operation. The change
864 reduces register usage a lot in some cases

3141 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3142 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3143 always available in leading double underscore form. The C99 support is
3144 mostly missing, but it's a start.
3145 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3224 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3226 * device/lib/printf_large.c: removed inline assembly for portability and
3227 readability. Use printf_fast if speed or size are more important.
3228 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3229 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3231 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3233 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3234 prevent compiler warning
3236 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3238 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3239 moved to level 0 and declared as static. Also they are explicit
3240 placed in access bank. This was necessery because some times they
3241 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3242 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3243 optimizations. Currently only compare to unsigned char is implemented,
3244 * src/pic16/gen.c: added fReturnIdx array,
3245 * (struct resolvedIfx) is moved to gen.h and made public,
3246 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3247 * (aopForSym): added an optimization to directly store in stack of
3248 the operand of a SEND iCode,
3249 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3250 but as registers instead (AOP_REG) using the fReturnIdx array,
3251 * (pic16_freeAsmop): remove the freed register from the
3252 _G.sregsAlloc field,
3253 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3254 a compare of 'WREG',
3255 * (pic16_popGetTempRegCond): changed function prototype, now
3256 function takes also a bitVector argument v which holds the current
3257 set of registers that are allocated for stack access by aopForSym,
3258 registers allocated in aopForSym for accessing stack symbols are not
3259 any more part of the functions usedRegs field,
3260 * (genCall): some times aopOp is called for a stack variable to be
3261 send, aopForSym might perform the push, if this is true make sure
3262 that genCall doesn't push the variable twice by testing _G.resDirect,
3263 * (genFunction): changed testing for unspecified interrupt number
3264 from 256 to INTNO_UNSPEC,
3265 * modified selection scheme of frame pointer generation. Previously
3266 if function did use local registers a frame pointer was generated,
3267 now a frame pointer is generated only if function has arguments
3268 (that need PLUSW2 register access), or has stack arguments, or the
3269 compiler is not instructed to omit the frame pointer,
3270 * (genEndFunction): before restoring local registers that were saved
3271 in the function preamble, also restore the registers that *might*
3272 have been allocated for stack access,
3273 * (genRet): removed some old comments,
3274 * (genCmp, the active (RN's) version): added a call to the
3275 pic16_genCmp_special function to perform the compare with a more
3276 robust and optimized way,
3277 * (genInline): a feature has been added in inline code generation,
3278 which allows a wildcard variable substitution when writing inline
3279 assembly. Code is incomplete and experimental therefore undocumented,
3280 * (genCast): changed order of aopOp for result and right to allow
3281 aopForSym to directly load the result if possible,
3282 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3283 perform an optimized compare on some selected special occasions,
3284 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3285 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3286 generate an IVT any more,
3287 * src/pic16/main.c (pic16_optionsTable): added command line option
3289 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3290 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3292 * src/pic16/NOTES: Raphael Neider added in list of active developers
3293 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3294 jumptable_end to prevent bug #,
3295 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3296 inCond and outCond fields,
3297 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3298 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3299 turn off register spilling,
3300 * (packRegsForOneUse): synced with other ports' versions although it
3301 is not used currently,
3302 * (pic16_packRegisters): added an optimization while reading
3303 structure bitfields, some registers may be saved (malloc code is
3304 decreased by 80 bytes)
3306 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3308 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3309 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3310 this can be optimized more?
3312 2005-03-10 Raphael Neider <rneider AT web.de>
3314 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3315 genNearPointerGet): (hopefully) fixed access to bitfields via
3316 pointers (p->bitN = x; and x = p->bitN; failed)

3950 Adding support for replacing ljmps with sjmps in jumptables
3951 generated for switch statements. For now you need to set the
3952 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3953 Now 4 algorithms for mcs51 jumptable generation are used:
3954 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3955 addresses loaded pc-relative for up to 112 cases and stack-pushing
3956 target addresses loaded with offset from dptr for up to 256 cases.
3958 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

3983 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3984 to call when a stack overflow occurs,
3985 * (malloc.h): added CVS Id tag,
3986 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3988 * added libc directory. The current version of LibC contains string
3989 functions, ctype functions and macros and some functions of the
3990 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3991 be extensively tested in the future. Standard disclaimer here.
3992 Library is not automatically build yet. But one can build it by
3993 invoking 'make' inside the libc directory.
3994 * added ADC library under libio. Preliminary version yet.
3996 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4003 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4004 * (pic16_storeForReturn): optimized return of 0,
4005 * (genCmp): experimental code for new genCmp which uses PIC18's
4006 special compare&skip instructions. Initial tests fail some times
4007 with variables grater than 1 byte in size, so new code is disabled,
4008 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4010 * (genCast): began a fix to optimize the casting of a bit to another
4011 bit, now assigning a bitfield to another bitfield will fail, sorry,
4012 * src/pic16/main.c: disabled the use of lr-support feature,
4013 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4016 bits with offset (case PO_GPR_BIT),
4017 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4019 * (isBankInstruction): modified to return 0 for no banking instruction,
4020 and 1 for banking instruction,
4021 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4022 caused stop processing pCodes after a inline assembly block,
4023 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4024 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4025 registers when it shouldn't,
4026 * src/pic16/ralloc.c (allocReg): add preliminary support for
4027 supporting a limited set of temporary registers,
4029 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4031 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4032 genDataPointerSet): ensure assignments always copy in MSB to LSB
4034 (loadRegFromAop): recognize CLRH optimization,
4035 (genFunction): optimize RECEIVE iCodes in reentrant functions
4037 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4039 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7034 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7036 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7037 loaded with the linker search paths (-L arguments) and the libraries
7038 to be linked with the current source (-l arguments). Changes
7039 currently will affect only the pic16 port.
7040 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7041 include path the port specific paths and port specific libraries,
7042 * gplink command now contains the $3 argument,
7043 * src/pic16/device.h,
7044 * src/pic16/device.c,: structure PIC_device is made public and
7045 renamed to PIC16_device, the same for variable Pics which is renamed

7058 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7060 Documenting changes from previous commits.
7061 * configure.in (version 1.56),
7062 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7063 when generating output files to configure the pic16 library,
7064 but now I've commented it out, since gputils aren't installed in the
7065 SF compile farm, so library won't compile
7067 * device/lib/Makefile.in (version 1.56): initially I've added in
7068 target 'all' the prerequestive 'model-pic16' so it compiled the
7069 pic16 library, but now I've commented it out for the same reasons
7071 * added targets 'model-pic16' and 'objects-pic16' to compile the
7073 * added target 'port-specific-objects-pic16' to handle the
7074 generated libraries and copy them into the build/ directory
7075 * added target 'clean-intermediate-pic16' to clean intermediate
7076 files into pic16 directory
7077 * in target 'installdirs' added line to create directory pic16 in
7078 the installation path
7080 * device/include/Makefile.in (version 1.11): in target 'install'
7081 added lines to copy all header files to installation path,
7082 * in target 'installdirs' added line create directory for pic16
7083 headers in the installation path
7085 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7098 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7099 option so that it actually works. Made it specific to the z80, since
7100 the gbz80 doesn't have these kinds of I/O ports.
7102 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7104 * device/include/z180.h,

7117 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7119 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7120 changed interrupt vector table generation to only emit declared vectors.
7121 * device/include/Makefile.in: added missing backslash
7122 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7124 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7126 Mainly changes to support compilation of the device libraries
7127 * src/pic16/device.c: stack is allocated via symbol and not
7128 via literal number. The symbol is placed in the corresponding
7129 position of the data ram
7130 * (pic16_dump_section): relocatable and absolute uninitialized
7131 data are now emitted in sorted order to reduce section naming,
7132 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7133 weren't marked as being in the access bank,
7135 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7137 Added portion of GNU PIC Library under the directory
7138 device/include/pic16 and device/lib/pic16. These files
7139 contain the declarations of SFRs for the PIC18Fxx2 devices.
7140 The directory is initialized via configure from toplevel.
7142 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7144 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7145 the spilllocations to be compared correctly
7147 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7149 * src/SDCCast.c (decorateType): fixed bug introduced today
7151 2004-01-12 Borut Razem <borut.razem AT siol.net>
7153 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7156 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7158 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7159 in simpler and even better code
7161 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7163 * src/SDCCicode.c (operandOperation): fixed bug #874819

7169 * doc/sdccman.lyx: Moved and added some sections, small changes
7170 all over. Telling LaTeX to be less strict with word spacing
7171 to better keep the right margin. Changed some notes about
7172 maintainance of the ports in section 3.2.1 - is it OK like this?
7174 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7176 SDCC source changes:
7177 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7211 UPPER for immediate operands,
7212 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7214 * src/pic16/peeph.def: all peepholes with movff are commented out,
7215 because there is a problem in the pcode peep optimizer,
7216 * src/pic16/ralloc.c: the register allocator can now reuse local
7217 function symbols for another function. This saves register usage.
7218 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7220 Added file src/pic16/NOTES with information about program writing on
7221 the current port version.

7230 * src/SDCCmain.c : fixed #872250: -l command line defined library
7231 files are scanned before standard library files
7233 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7250 gen51Code): more efficient parameter receive for --model-large
7253 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7256 * src/z80/main.c: added missed needLinkerScript flags (more than
7257 one port structure defined in these file)
7258 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7274 needLinkerScript flag
7276 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7277 * src/pic/glue.c: added variable udata_section_name to
7278 override default uninitialized data segment definition for
7279 devices only with SHAREBANK memory (reported from Erik Epetrich)
7280 * (pic14emitOverlay): modified to emit a commented overlay segment
7281 directive when no overlay data exist
7282 * (picglue): modified to emit uninitialized data segment
7283 according to udata_section_name

7288 arguments via -W option
7289 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7290 object file from '.rel' to '.o' in port->linker structure,
7291 changed size of fptr from 2 to 3 in port structure
7293 2004-01-07 Borut Razem <borut.razem AT siol.net>
7295 * support/scripts/sdcc.nsi: update PATH
7296 * support/scripts/sdcc.ico: craeted
7298 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7309 include information about variables allocated to the overlay
7312 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7314 * as/mcs51/lkmain.c: Help about -Y option

7326 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7328 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7329 (default behaviour).
7331 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7333 A python script to validate compiler diagnostic messages. It can be
7334 used to verify that sdcc complains about bad c source code and
7335 gives a good location of the error.
7336 * support/valdiag/Makefile,
7337 * support/valdiag/valdiag.py,
7338 * support/valdiag/tests/*
7340 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7342 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7353 * src/common.h: added ifndef/define/endif macros
7354 around the header file.
7355 Bug reported from Jesus Calvino-Fraga
7357 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7359 * sdcc.spec: updated
7360 * device/include/Makefile.in: don't install CVS directories
7361 * device/lib/Makefile.in: added removal of CVS directories after install
7362 * doc/Makefile: fixed install, added local_icons
7363 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7364 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7365 * src/ds390/gen.c (genRightShift): fixed bug #870788
7366 * src/SDCCast.c (decorateType): fixed bug #870781
7368 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7370 PIC16 port related changes:
7371 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7372 added variable stackPos,
7374 * gen.c: genCall, assignResultValue: added support for
7375 pushing/retrieving function parameters to/from stack,
7376 genFunction,genEndFunction: setup stack frame for the
7378 genAddrOf: will be changed according to bug 863624
7380 * added files genutils.c and genutils.h which contain gen*
7381 debugged and optimised functions extracted from gen.c
7383 * glue.c: added variable 'externs' which holds extern symbols,
7384 pic16emitRegularMap: is modified to properly handle relocatable
7385 symbols under the new scheme,
7386 pic16createInterruptVect: is modified
7387 pic16printPublics: is modified to emit 'global' assembler directives,
7388 added pic16_printExterns to print extern symbols,
7389 pic16glue: initializes stack/frame pointer in the beginning of
7390 the assembly output. Temporary hack, will be corrected later,
7391 because gplink yet does not support stack and SDCC does not
7392 yet support a type of crt0.o object to create the final binary.
7394 * Removed many lines that contain 8051 legacy code.
7395 * The code is finally placed under a 'code' directive.
7396 * Added port specific options.
7398 * _process_pragma: simplified since now we do not need *special*
7399 include file to define SFR registers. But a separate header
7400 will be needed. This will be developed later.
7401 * _pic16_parseOptions: added, parses port specific options:
7402 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7403 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7404 --preplace-udata-with=
7406 * _pic16_setDefaultOptions: modified to initialize section names,
7407 but hack is temporarly out of order since it needs improvement.
7408 * _pic16_genAssemblerPreamble: configuration words are emitted by
7409 their address instead of their name. This part is incomplete and
7410 supports only the 18Fxx2 devices. Other devices will emit an error
7411 during assembly since they do not contain the same set of config
7413 * _pic16_genIVT: is modified,
7415 * pcode.c: added definitions for some hardware registers that are needed
7417 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7418 All PCI entries are updated. Now LFSR is supported.
7419 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7420 * added pic16_newpCodeOpLit2 to support instructions with
7421 two literal arguments
7422 * pic16_pCode2str: corrected code that emits assembler instructions
7423 with two literal operands and those that have an access bit modifier
7424 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7425 this fixes a bug which caused some labels to be lost, when an
7426 assembler directive was added, i.e. banksel,
7427 * pic16_FixRegisterBanking: improved logic that causes the insertion
7429 * InlineFunction: functions that are called once, are not any more
7430 inlined. This can be a port option in the future,
7432 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7434 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7435 hold the corresponding uninitialized symbols,
7436 * pic16_allocProcessorRegister: registers have explicit marked the
7438 * pic16_allocInternalRegister: registers are explicit marked as
7440 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7441 processing list, so bit registers were lost,
7444 * ralloc.h: added field 'accessBank' and original symbol operand
7445 in register definition,
7446 * removed the field isMapped from register definition,
7448 ** Several functions have been removed from various sources:
7449 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7450 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7451 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7452 pic16_assignRelocatableRegisters
7454 ** others have been introduced:
7455 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7456 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7458 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7460 * support/scripts/inc2h.pl: changed definition of BIT_AT
7461 to emit 'sbit at' instead of 'bit at'. This was a request.
7463 PIC16 port related preliminary changes:
7464 * gen.c: prefixed function popRegFromString with
7465 pic16_ and all references to it corrected
7466 * pcode.c: all pic16_pc_* hardware registers prefixed
7467 with underscore (_),
7468 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7469 * ralloc.c: newReg(): when register is REG_SFR then
7470 set address to rIdx,
7471 pic16_allocProcessorRegister(): marks register wasUsed=0
7472 pic16_writeUsedRegs(): added a call to assign processor
7473 registers via pic16_assignFixedRegisters
7475 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7477 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7478 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7479 variables in unused register banks. Also the SSEG is placed
7480 wherever there is enough space for it, and IDATA can be anywhere
7481 in internal RAM. For now compile using -Wl-Y[stack_size].
7482 The mem file is different for this option as well, since it
7483 makes no sense of talking about DSEG lenght.

8478 and JUMPTABLE iCodes properly now (worked by accident before)
8479 * src/mcs51/gen.c (leftRightUseAcc),
8480 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8481 iCode properly now. Use getSize instead of nRegs since a & b
8482 aren't part of the nRegs tally.
8484 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8486 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8487 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8488 before instructions that use the _STATUS register
8490 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8492 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8493 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8494 fetching of the pointer
8495 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8496 copied from genNearPointerSet()
8497 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8498 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8499 If they pop r0/r1 they must be called in the opposite order than aopOp().
8500 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8501 (resp. --stack-auto), prepared for --xstack
8503 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8507 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8509 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8510 these ports have their own __sdcc_external_start()
8512 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8514 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8515 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8516 type for bits was changed. It resulted in bit variables becoming
8517 global, which is not permitted in PIC 14 assembly output.
8519 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8521 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8523 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8525 Z80 and MCS51 linkers complaint if a public symbol is defined
8526 in more than one library module:

8532 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8534 A few small changes that speed up the peephole optimizer.
8538 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8540 Try to make the peephole optimizer smarter by maintaining
8541 an association between the assembly source code and the
8542 iCodes that originated them. Put this information to use
8543 with a new peephole rule condition "notVolatile" so that
8544 the rules can be aggressive yet still safe.
8549 * src/mcs51/peeph.def
8551 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8555 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8556 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8557 if the left or right operand symbols have the accuse flag set.
8559 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8561 Changed the type of the result of the ! (NOT) operator to char;
8562 previously it returned the same type as the source. This allows
8563 us to eliminate all the genFloatNot functions (all of its target
8564 implementations were very buggy) since !float can use the same
8567 * src/SDCCicode.c (ast2iCode): ! returns char
8568 * src/mcs51/gen.c (genNot, genNotFloat),
8569 * src/ds390/gen.c (genNot, genNotFloat),
8570 * src/z80/gen.c (genNot, genNotFloat),
8571 * src/pic/gen.c (genNot, genNotFloat),
8572 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8574 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8576 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8577 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8578 during interrupts. Ensure WSAVE is located at a shared bank address.
8579 2. Fixed page selection in some places
8580 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8581 the registers name strings.
8582 4. Fixed "signed / unsigned compare" compiler warnings.
8583 5. The PIC port manages its own allocation of the general purpose
8584 registers, but makes no attempt to reuse them. As a result when
8585 compiling it soon runs out of general purpose registers. Some
8586 additional code was added to the files pcode.c and device.c to walk
8587 through the function call tree and rename the registers so that they
8597 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8598 genPlus() & genMinus() when the result is the same as left or right

8604 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8606 Made bitfield a distinct type from bit so that bitfields
8607 convert as per ANSI C and bits retain their traditional
8608 boolean style behaviour. Implemented bitfield support in
8616 * src/ds390/gen.c: bit v bitfield split
8617 * src/z80/gen.c: New support for bitfields
8618 * support/regression/tests/bitfields.c: reenabled z80,
8621 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8623 Rules 246.x, 247.x relate to bitfields, the others speed up
8624 access to xdata mapped I/O devices.
8626 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8628 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8630 Cleaned up genPackBits and genUnpackBits and added two helper
8631 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8632 for literal assignments in genPackBits (thanks to Frieder for
8638 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8640 Fixed bug #748310 (pointer to function type mishandled when the
8641 function name is omitted). Also fixed a SIGSEGV when a function
8642 attribute (reentrant, etc) is used on a non-function or on a
8643 function but misplaced before the parameter list.
8645 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8647 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8648 * support/Util/SDCCerr.h,
8649 * support/Util/SDCCerr.c: Added func attr misuse error msg

8670 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8672 Made the constant following the "interrupt" keyword optional. If
8673 omitted, the function will not automatically be given an entry
8674 in the interrupt vector table (similar to #pragma NOIV, but
8675 less syntacticly kludgy). The interrupt number is also now
8676 range checked. Also fixed a bug in the high order bit example
8683 * support/Util/SDCCerr.c
8684 * support/Util/SDCCerr.h
8687 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8690 * src/SDCCicode.c (operandOperation): rewritten some ops
8691 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8692 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8694 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8695 be re-activated by defining REDUCE_LITERALS)
8696 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8697 unsigned, but are signed by default
8698 * src/SDCCval.c (constVal): rearranged
8699 * src/SDCCval.c (valMod): preliminary fix
8700 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8743 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8744 * src/SDCCval.c (valDiv, valMod): fixed signdness
8745 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8746 signedness of modulo, left and right shift

9152 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9153 the regression tests I'm not brave enough to enable 245.b, 245.c
9154 * doc/sdccman.lyx: added latex preamble for hyperref package.
9155 Using pdflatex this will give you a hyperlinked pdf file with
9156 bookmarks. (prepend '%' before /usepackage if this breaks something)

9172 Applied patch from bug 737905 (renamed yylineo to mylineno):
9179 * src/pic16/pcode.c: Cleaned warnings
9180 * src/pic16/pcodeflow.c: Cleaned warnings
9181 * src/pic16/pcoderegs.c: Cleaned warnings

9197 it can be defined with CFLAGS when running configure
9198 * src/SDCCmain.c: fixed compiling + linking with object files
9200 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9203 added --disable-pic16-port
9204 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9205 * src/SDCCmain.c: linkOptions is changed to set *,
9206 added if/endif conditional macros to remove options help
9207 messages from optionsTable when a port is not configured, added
9208 support for the PIc16 port in the ports table, when executing
9209 the compiler with no port specified on command line, a default
9210 port is selected with the new macro DEFAULT_PORT which is
9211 defined in port.h, in setDefaultOptions() linkOptions is removed
9212 from initialization assignment, since now it is a set,
9213 parseCmdLine uses setParseWithComma for linkOptions, in
9214 linkEdit() linkOptions are accessed with new function indexSet()
9215 which returns the i'th item of a set variable. See SDCCset.c, in
9216 linkEdit() when calling buildCmdLine(), added linkOptions as
9217 last argument. Now users can pass arguments to gplink via the
9218 -Wl option, main() uses pic16glue() to glue up pic16 programs

9230 * src/pic16/glue.c: commented out some error producing lines
9231 * src/pic16/main.c: __config directives are commented out to stop
9232 gpasm complaining and test the linkage with gplink, _linkCmd and
9233 _asmCmd changed to be more gplink and gpasm friendly
9234 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9235 produced an error when parsed, peep rule 12 is added to utilize
9236 movff, but it is commented out since the pCode does not support
9237 yet a command with 2 address arguments
9239 2003-05-18 <johan AT balder>
9241 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9242 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9266 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9268 2003-05-11 Borut Razem <borut.razem AT siol.net>
9270 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9271 the path of bin directory, so that PATH is the only env. variable, which has to be set
9272 in case of standard installation.
9273 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10305 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10306 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10307 following files to include the previous two files: aslink.dsp,
10308 Makefile.aslink, Makefile.bcc, and Makefile.in.
10310 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10311 .adb instead of .cdb
10313 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10315 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10316 value from option --iram-size.
10318 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10320 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10323 2002-09-18 <wiml AT hhhh.org>
10325 * SDCClrange.h: exposed setFromRange() and setToRange()
10326 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10327 packRegsForAccUse() (bug 542397)
10328 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10329 multiple times and emitting the fetch operations more than once
10330 added aopGetUsesAcc() function to allow binary operators to
10331 fetch their operands in the correct order; made genMinus() emit
10332 compact code for X = LITERAL - Y
10334 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10335 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

10338 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10339 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10342 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10343 Changes to aslink (All the changes are marked with 'JCF'):
10345 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10348 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10349 area BSEG. Also moves, if possible, the DATA area down into the internal
10350 ram so more space is available.
10352 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10355 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10356 not bytes. Function summary() which creates a memory usage summary
10357 file with extension .mem. Reports of overlaping stack and small stack
10358 size. If the space for the stack is less than 16 bytes aslink trows a
10361 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10362 the 8051. Option 'y' for memory summary output file.
10364 Changes to sdcc (All the changes are marked with 'JCF'):
10366 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10368 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10369 overlaying area for it (uses RegBankUsed[4]).
10371 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10372 bank zero as used by default. By default aslink locates the stack
10373 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10374 the creation of the .mem file. Delegates the allocation of data area
10375 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10376 the begining of the stack area to aslink.
10378 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10379 glue() in SDCCglue.c creates an area for it.
10381 2002-09-03 Borut Razem <borut.razem AT siol.net>
10382 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10383 sdcc/src/pic/glue.c:
10384 introduced atexit() handler for teporay files removal in case of
10385 errors, assertions, ...
10387 2002-08-29 Borut Razem <borut.razem AT siol.net>
10388 * sdcc/support/cpp2/auto-host_vc_in.h:
10389 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10390 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10391 Maybe there is a similar problem with BORLANDC? It should be checked!
10393 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10394 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10395 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10396 was not executed, and the compiler (cl) launched a warning:
10397 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10399 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10400 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10402 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10403 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
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 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10408 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10409 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10410 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10411 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10412 - added Release configuration in VS projects
10413 - review of compiler an linker options
10414 - VC .exe files are generated in bin_vc directory, not to interfere
10415 with binaries generated from other projects (cygwin, mingw, bcc ...)
10417 * sdcc/src/yacc.dsp: added
10419 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10420 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10421 and insert the version number definitions from .version
10423 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10425 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10426 added - genarate auto-host.h using auto-host_vc_in.h as template
10429 removed from CVS, generated automatically
10431 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10432 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10434 2002-08-11 Borut Razem <borut.razem AT siol.net>
10435 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10437 2002-08-10 Borut Razem <borut.razem AT siol.net>
10438 * src/SDCCmain.c (main):
10439 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10440 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10441 The consequence was that some temporary files were not removed.
10444 unification of code in functions tempfilename() and tempfile():
10445 function tempnam() is defined in Visual Studio 6.0 and .NET
10447 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10449 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10450 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10451 - removed compiler command line option /WX: Treats all warnings as errors
10452 - update a list of source files, included into the project
10454 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10455 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10456 changed project type to Generic Project so that can be correcly converted to VS.NET project
10458 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10460 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10462 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10464 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10465 added return 0 statements after assert() to make compiler happy
10467 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10468 added newline in the def file to keep MSC compiler satisfied
10470 * sdcc/src/z80/gen.c:
10471 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10472 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10473 - solved MSC error in function aopDump()
10475 * sdcc_vc.h: define PREFIX as "\\sdcc"
10477 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10478 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10650 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10652 * sdcc/src/SDCCloop.c:
10653 Previous fix was not good. basic blocks that have "break" or "return" are
10654 not really partof a loop , but live ranges used in these blocks should
10655 be live thru the entire loop, so set partOfLoop but don't add them to
10658 2002-02-21 <johan AT FRIJA>
10660 * src/SDCCcse.c: fixed bug #514308
10662 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
