381 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
383 Enabled VPATH feature: changed nearly all Makefiles (149 files).
384 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
386 One basic decision: e.g. src/clean.mk includes further files. In order
387 to make this work there are two solutions:
388 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
389 run configure on them. This way they can use
390 'include $(srcdir)/port-clean.mk'
391 - always include clean.mk by the Makefile at the same level. To avoid
392 that `make clean` tries to include and build Makefile.dep the
393 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
394 implemented, because now even `make uninstall` doesn't create
395 Makefile.in. clean.mk could be eliminated by pasting it in
398 * debugger/mcs51/Makefile.in: build own objects from library sources
399 (SLIB, SDCC) in current directory
401 * configure, configure.in: renamed --disable-device-lib-build in
402 --disable-device-lib; added --enable-doc, the required tools are
403 searched by configure; added result message; the toolchain for the
404 belonging ports are now only built, if the port is enabled.
406 * support/regression/*: all output is written in directory gen, because
407 the fwk and ports directories don't livet in the build tree using vpath
409 * doc/sdccman.lyx: renamed --disable-device-lib-build to
410 --disable-device-lib, added --enable-doc, added section VPATH
412 * sim/ucsim/configure.in,
413 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
414 z80 are enabled by default
416 2006-04-24 Raphael Neider <rneider AT web.de>
418 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
419 to config word, "pic14_"-prefixed some extern functions
420 (pic14_emitConfigWord): emit __config directive(s) if assignment to
421 config word has been found
422 * src/pic/device.h: added prototypes
423 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

440 fixes #1469504 and #1474602,
441 (pCodeRegOptimizeRegUsage): fixed typo in comment
443 2006-04-24 Borut Razem <borut.razem AT siol.net>
445 * device/examples/main8051.c: deleted - it was removed from CVS
446 24.mar.2000 and after that modified 18.feb.2001, so it reappered
447 after the transition to Subversion
448 * src/SDCCalloc.h: deleted - it was removed from CVS
449 3.feb.2001 and after that modified 18.feb.2001, so it reappered
450 after the transition to Subversion

701 2006-03-16 Raphael Neider <rneider AT web.de>
703 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
704 the left operand is shorter than the result (c* = lit-c* + int),
706 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
709 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
711 * src/.version: increased version number to 2.5.5
712 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
713 linking is done manually in pic16 port's _linkEdit,
714 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
715 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

3088 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3090 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3094 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3095 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3096 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3097 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3098 always available in leading double underscore form. The C99 support is
3099 mostly missing, but it's a start.
3100 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3101 reserved identifier "__data".
3103 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3149 2005-03-20 Borut Razem <borut.razem AT siol.net>
3151 * support/scripts/inc2h.pl: WIN32 port

3179 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3181 * device/lib/printf_large.c: removed inline assembly for portability and
3182 readability. Use printf_fast if speed or size are more important.
3183 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3184 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3186 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3188 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3189 prevent compiler warning
3191 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3193 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3194 moved to level 0 and declared as static. Also they are explicit
3195 placed in access bank. This was necessery because some times they
3196 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3197 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3198 optimizations. Currently only compare to unsigned char is implemented,
3199 * src/pic16/gen.c: added fReturnIdx array,
3200 * (struct resolvedIfx) is moved to gen.h and made public,
3201 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3202 * (aopForSym): added an optimization to directly store in stack of
3203 the operand of a SEND iCode,
3204 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3205 but as registers instead (AOP_REG) using the fReturnIdx array,
3206 * (pic16_freeAsmop): remove the freed register from the
3207 _G.sregsAlloc field,
3208 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3209 a compare of 'WREG',
3210 * (pic16_popGetTempRegCond): changed function prototype, now
3211 function takes also a bitVector argument v which holds the current
3212 set of registers that are allocated for stack access by aopForSym,
3213 registers allocated in aopForSym for accessing stack symbols are not
3214 any more part of the functions usedRegs field,
3215 * (genCall): some times aopOp is called for a stack variable to be
3216 send, aopForSym might perform the push, if this is true make sure
3217 that genCall doesn't push the variable twice by testing _G.resDirect,
3218 * (genFunction): changed testing for unspecified interrupt number
3219 from 256 to INTNO_UNSPEC,
3220 * modified selection scheme of frame pointer generation. Previously
3221 if function did use local registers a frame pointer was generated,
3222 now a frame pointer is generated only if function has arguments
3223 (that need PLUSW2 register access), or has stack arguments, or the
3224 compiler is not instructed to omit the frame pointer,
3225 * (genEndFunction): before restoring local registers that were saved
3226 in the function preamble, also restore the registers that *might*
3227 have been allocated for stack access,
3228 * (genRet): removed some old comments,
3229 * (genCmp, the active (RN's) version): added a call to the
3230 pic16_genCmp_special function to perform the compare with a more
3231 robust and optimized way,
3232 * (genInline): a feature has been added in inline code generation,
3233 which allows a wildcard variable substitution when writing inline
3234 assembly. Code is incomplete and experimental therefore undocumented,
3235 * (genCast): changed order of aopOp for result and right to allow
3236 aopForSym to directly load the result if possible,
3237 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3238 perform an optimized compare on some selected special occasions,
3239 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3240 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3241 generate an IVT any more,
3242 * src/pic16/main.c (pic16_optionsTable): added command line option
3244 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3245 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3247 * src/pic16/NOTES: Raphael Neider added in list of active developers
3248 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3249 jumptable_end to prevent bug #,
3250 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3251 inCond and outCond fields,
3252 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3253 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3254 turn off register spilling,
3255 * (packRegsForOneUse): synced with other ports' versions although it
3256 is not used currently,
3257 * (pic16_packRegisters): added an optimization while reading
3258 structure bitfields, some registers may be saved (malloc code is
3259 decreased by 80 bytes)
3261 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3263 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3264 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3265 this can be optimized more?
3267 2005-03-10 Raphael Neider <rneider AT web.de>
3269 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3270 genNearPointerGet): (hopefully) fixed access to bitfields via
3271 pointers (p->bitN = x; and x = p->bitN; failed)
3273 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3275 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3316 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3317 to keep the correct label reference count when adding/removing references
3318 to labels. A peephole file using this is appended to patch #1144962.
3320 2005-02-14 Raphael Neider <rneider AT web.de>

3450 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3451 (sizeof(sectNames) changed to sizeof(sectName))
3452 Both patches fix segfaults under MinGW.
3454 2005-01-23 Raphael Neider <rneider AT web.de>

3457 Safe_[mc]?alloc()'ed variables
3458 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3459 of (byte sized) temporaries (assign them to WREG for now)
3460 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3461 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3462 this might fix SIGSEGVs on MinGW...
3463 * src/SDCCopt.c (killDeadCode): restored original behaviour
3464 (volatile operands might get thrown away though)
3466 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3468 * src/pic16/gen.c: fixed bug #1106975,

3899 2004-12-02 Slade Rich <slade_rich AT users.sourceforge.net>
3901 * device/include/pic/pic16f877.h : added an include file for the PIC16F877 device.
3903 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3905 Adding support for replacing ljmps with sjmps in jumptables
3906 generated for switch statements. For now you need to set the
3907 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3908 Now 4 algorithms for mcs51 jumptable generation are used:
3909 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3910 addresses loaded pc-relative for up to 112 cases and stack-pushing
3911 target addresses loaded with offset from dptr for up to 256 cases.
3913 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3914 * src/mcs51/main.c: adapted constants for switch table generation
3915 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

3935 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
3937 Large cummulative patch for pic16 port.
3938 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3939 to call when a stack overflow occurs,
3940 * (malloc.h): added CVS Id tag,
3941 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3943 * added libc directory. The current version of LibC contains string
3944 functions, ctype functions and macros and some functions of the
3945 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3946 be extensively tested in the future. Standard disclaimer here.
3947 Library is not automatically build yet. But one can build it by
3948 invoking 'make' inside the libc directory.
3949 * added ADC library under libio. Preliminary version yet.
3951 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
3952 * src/pic16/gen.c (aopForRemat): asmop size is filled by
3953 aopForRemat() now and not by pic16_aopOp(),

3955 temporary registers, its a buggy feature and will be removed,
3956 * (pic16_popGet): set register instance field in AOP_CRY,
3957 * (pic16_outBitC): fixed for results in size greater than 1,
3958 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3959 * (pic16_storeForReturn): optimized return of 0,
3960 * (genCmp): experimental code for new genCmp which uses PIC18's
3961 special compare&skip instructions. Initial tests fail some times
3962 with variables grater than 1 byte in size, so new code is disabled,
3963 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3965 * (genCast): began a fix to optimize the casting of a bit to another
3966 bit, now assigning a bitfield to another bitfield will fail, sorry,
3967 * src/pic16/main.c: disabled the use of lr-support feature,
3968 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3969 * added some function prototypes, added function _debugf prototype,
3970 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
3971 bits with offset (case PO_GPR_BIT),
3972 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3974 * (isBankInstruction): modified to return 0 for no banking instruction,
3975 and 1 for banking instruction,
3976 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3977 caused stop processing pCodes after a inline assembly block,
3978 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3979 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3980 registers when it shouldn't,
3981 * src/pic16/ralloc.c (allocReg): add preliminary support for
3982 supporting a limited set of temporary registers,
3984 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3986 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3987 genDataPointerSet): ensure assignments always copy in MSB to LSB
3989 (loadRegFromAop): recognize CLRH optimization,
3990 (genFunction): optimize RECEIVE iCodes in reentrant functions
3992 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3994 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
3995 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
3997 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

6992 loaded with the linker search paths (-L arguments) and the libraries
6993 to be linked with the current source (-l arguments). Changes
6994 currently will affect only the pic16 port.
6995 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6996 include path the port specific paths and port specific libraries,
6997 * gplink command now contains the $3 argument,
6998 * src/pic16/device.h,
6999 * src/pic16/device.c,: structure PIC_device is made public and
7000 renamed to PIC16_device, the same for variable Pics which is renamed
7001 to Pics16. Updated all references to them.
7002 * src/pic16/glue.c (pic16glue): corrected bug with code
7003 initialization which bypassed the variable initializations block.
7005 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7006 COMPILE_FLAGS and added the --nostdinc option
7008 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7010 * device/include/mc68hc908jb8.h: Register defs for another member

7013 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7015 Documenting changes from previous commits.
7016 * configure.in (version 1.56),
7017 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7018 when generating output files to configure the pic16 library,
7019 but now I've commented it out, since gputils aren't installed in the
7020 SF compile farm, so library won't compile
7022 * device/lib/Makefile.in (version 1.56): initially I've added in
7023 target 'all' the prerequestive 'model-pic16' so it compiled the
7024 pic16 library, but now I've commented it out for the same reasons
7026 * added targets 'model-pic16' and 'objects-pic16' to compile the
7028 * added target 'port-specific-objects-pic16' to handle the
7029 generated libraries and copy them into the build/ directory
7030 * added target 'clean-intermediate-pic16' to clean intermediate
7031 files into pic16 directory
7032 * in target 'installdirs' added line to create directory pic16 in
7033 the installation path
7035 * device/include/Makefile.in (version 1.11): in target 'install'
7036 added lines to copy all header files to installation path,
7037 * in target 'installdirs' added line create directory for pic16
7038 headers in the installation path

7053 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7054 option so that it actually works. Made it specific to the z80, since
7055 the gbz80 doesn't have these kinds of I/O ports.
7057 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7059 * device/include/z180.h,

7072 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7074 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7075 changed interrupt vector table generation to only emit declared vectors.

7081 Mainly changes to support compilation of the device libraries
7082 * src/pic16/device.c: stack is allocated via symbol and not
7083 via literal number. The symbol is placed in the corresponding
7084 position of the data ram
7085 * (pic16_dump_section): relocatable and absolute uninitialized
7086 data are now emitted in sorted order to reduce section naming,
7087 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7088 weren't marked as being in the access bank,
7090 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7092 Added portion of GNU PIC Library under the directory
7093 device/include/pic16 and device/lib/pic16. These files
7094 contain the declarations of SFRs for the PIC18Fxx2 devices.
7095 The directory is initialized via configure from toplevel.
7097 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7099 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7100 the spilllocations to be compared correctly
7102 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7104 * src/SDCCast.c (decorateType): fixed bug introduced today
7106 2004-01-12 Borut Razem <borut.razem AT siol.net>

7124 * doc/sdccman.lyx: Moved and added some sections, small changes
7125 all over. Telling LaTeX to be less strict with word spacing
7126 to better keep the right margin. Changed some notes about
7127 maintainance of the ports in section 3.2.1 - is it OK like this?
7129 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7166 UPPER for immediate operands,
7167 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7169 * src/pic16/peeph.def: all peepholes with movff are commented out,
7170 because there is a problem in the pcode peep optimizer,
7171 * src/pic16/ralloc.c: the register allocator can now reuse local

7173 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7175 Added file src/pic16/NOTES with information about program writing on
7176 the current port version.

7185 * src/SDCCmain.c : fixed #872250: -l command line defined library
7186 files are scanned before standard library files
7188 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7205 gen51Code): more efficient parameter receive for --model-large
7208 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7211 * src/z80/main.c: added missed needLinkerScript flags (more than
7212 one port structure defined in these file)
7213 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7229 needLinkerScript flag
7231 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7232 * src/pic/glue.c: added variable udata_section_name to
7233 override default uninitialized data segment definition for
7234 devices only with SHAREBANK memory (reported from Erik Epetrich)
7235 * (pic14emitOverlay): modified to emit a commented overlay segment
7236 directive when no overlay data exist
7237 * (picglue): modified to emit uninitialized data segment
7238 according to udata_section_name

7244 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7245 object file from '.rel' to '.o' in port->linker structure,
7246 changed size of fptr from 2 to 3 in port structure
7248 2004-01-07 Borut Razem <borut.razem AT siol.net>
7250 * support/scripts/sdcc.nsi: update PATH
7251 * support/scripts/sdcc.ico: craeted
7253 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7264 include information about variables allocated to the overlay
7267 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7269 * as/mcs51/lkmain.c: Help about -Y option

7281 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7283 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7284 (default behaviour).
7286 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7288 A python script to validate compiler diagnostic messages. It can be
7289 used to verify that sdcc complains about bad c source code and
7290 gives a good location of the error.
7291 * support/valdiag/Makefile,
7292 * support/valdiag/valdiag.py,
7293 * support/valdiag/tests/*
7295 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7297 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7308 * src/common.h: added ifndef/define/endif macros
7309 around the header file.
7310 Bug reported from Jesus Calvino-Fraga
7312 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7314 * sdcc.spec: updated
7315 * device/include/Makefile.in: don't install CVS directories
7316 * device/lib/Makefile.in: added removal of CVS directories after install
7317 * doc/Makefile: fixed install, added local_icons
7318 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7319 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7320 * src/ds390/gen.c (genRightShift): fixed bug #870788
7321 * src/SDCCast.c (decorateType): fixed bug #870781
7323 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7325 PIC16 port related changes:
7326 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7327 added variable stackPos,
7329 * gen.c: genCall, assignResultValue: added support for
7330 pushing/retrieving function parameters to/from stack,
7331 genFunction,genEndFunction: setup stack frame for the
7333 genAddrOf: will be changed according to bug 863624
7335 * added files genutils.c and genutils.h which contain gen*
7336 debugged and optimised functions extracted from gen.c
7338 * glue.c: added variable 'externs' which holds extern symbols,
7339 pic16emitRegularMap: is modified to properly handle relocatable
7340 symbols under the new scheme,
7341 pic16createInterruptVect: is modified
7342 pic16printPublics: is modified to emit 'global' assembler directives,
7343 added pic16_printExterns to print extern symbols,
7344 pic16glue: initializes stack/frame pointer in the beginning of
7345 the assembly output. Temporary hack, will be corrected later,
7346 because gplink yet does not support stack and SDCC does not
7347 yet support a type of crt0.o object to create the final binary.
7349 * Removed many lines that contain 8051 legacy code.
7350 * The code is finally placed under a 'code' directive.
7351 * Added port specific options.
7353 * _process_pragma: simplified since now we do not need *special*
7354 include file to define SFR registers. But a separate header
7355 will be needed. This will be developed later.
7356 * _pic16_parseOptions: added, parses port specific options:
7357 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7358 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7359 --preplace-udata-with=
7361 * _pic16_setDefaultOptions: modified to initialize section names,
7362 but hack is temporarly out of order since it needs improvement.
7363 * _pic16_genAssemblerPreamble: configuration words are emitted by
7364 their address instead of their name. This part is incomplete and
7365 supports only the 18Fxx2 devices. Other devices will emit an error
7366 during assembly since they do not contain the same set of config
7368 * _pic16_genIVT: is modified,
7370 * pcode.c: added definitions for some hardware registers that are needed
7372 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7373 All PCI entries are updated. Now LFSR is supported.
7374 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7375 * added pic16_newpCodeOpLit2 to support instructions with
7376 two literal arguments
7377 * pic16_pCode2str: corrected code that emits assembler instructions
7378 with two literal operands and those that have an access bit modifier
7379 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7380 this fixes a bug which caused some labels to be lost, when an
7381 assembler directive was added, i.e. banksel,
7382 * pic16_FixRegisterBanking: improved logic that causes the insertion
7384 * InlineFunction: functions that are called once, are not any more
7385 inlined. This can be a port option in the future,
7387 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7389 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7390 hold the corresponding uninitialized symbols,
7391 * pic16_allocProcessorRegister: registers have explicit marked the
7393 * pic16_allocInternalRegister: registers are explicit marked as
7395 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7396 processing list, so bit registers were lost,
7399 * ralloc.h: added field 'accessBank' and original symbol operand
7400 in register definition,
7401 * removed the field isMapped from register definition,
7403 ** Several functions have been removed from various sources:
7404 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7405 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7406 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7407 pic16_assignRelocatableRegisters
7409 ** others have been introduced:
7410 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7411 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7413 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7415 * support/scripts/inc2h.pl: changed definition of BIT_AT
7416 to emit 'sbit at' instead of 'bit at'. This was a request.
7418 PIC16 port related preliminary changes:
7419 * gen.c: prefixed function popRegFromString with
7420 pic16_ and all references to it corrected
7421 * pcode.c: all pic16_pc_* hardware registers prefixed
7422 with underscore (_),
7423 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7424 * ralloc.c: newReg(): when register is REG_SFR then
7425 set address to rIdx,
7426 pic16_allocProcessorRegister(): marks register wasUsed=0
7427 pic16_writeUsedRegs(): added a call to assign processor
7428 registers via pic16_assignFixedRegisters
7430 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7432 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7433 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7434 variables in unused register banks. Also the SSEG is placed
7435 wherever there is enough space for it, and IDATA can be anywhere
7436 in internal RAM. For now compile using -Wl-Y[stack_size].
7437 The mem file is different for this option as well, since it
7438 makes no sense of talking about DSEG lenght.
7440 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7442 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7443 in certain cases, e.g. when ROM assignment, patch provided
7444 from Albert den Haan.
7446 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8489 A few small changes that speed up the peephole optimizer.
8493 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8495 Try to make the peephole optimizer smarter by maintaining
8496 an association between the assembly source code and the
8497 iCodes that originated them. Put this information to use
8498 with a new peephole rule condition "notVolatile" so that
8499 the rules can be aggressive yet still safe.
8504 * src/mcs51/peeph.def
8506 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8510 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8511 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8512 if the left or right operand symbols have the accuse flag set.
8514 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8516 Changed the type of the result of the ! (NOT) operator to char;
8517 previously it returned the same type as the source. This allows
8518 us to eliminate all the genFloatNot functions (all of its target
8519 implementations were very buggy) since !float can use the same
8522 * src/SDCCicode.c (ast2iCode): ! returns char

8531 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8532 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8533 during interrupts. Ensure WSAVE is located at a shared bank address.
8534 2. Fixed page selection in some places
8535 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8536 the registers name strings.
8537 4. Fixed "signed / unsigned compare" compiler warnings.
8538 5. The PIC port manages its own allocation of the general purpose
8539 registers, but makes no attempt to reuse them. As a result when
8540 compiling it soon runs out of general purpose registers. Some
8541 additional code was added to the files pcode.c and device.c to walk
8542 through the function call tree and rename the registers so that they
8552 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8553 genPlus() & genMinus() when the result is the same as left or right

8559 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8561 Made bitfield a distinct type from bit so that bitfields
8562 convert as per ANSI C and bits retain their traditional
8563 boolean style behaviour. Implemented bitfield support in
8571 * src/ds390/gen.c: bit v bitfield split
8572 * src/z80/gen.c: New support for bitfields
8573 * support/regression/tests/bitfields.c: reenabled z80,
8576 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8578 Rules 246.x, 247.x relate to bitfields, the others speed up
8579 access to xdata mapped I/O devices.
8581 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8583 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8585 Cleaned up genPackBits and genUnpackBits and added two helper
8586 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8587 for literal assignments in genPackBits (thanks to Frieder for
8593 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8595 Fixed bug #748310 (pointer to function type mishandled when the
8596 function name is omitted). Also fixed a SIGSEGV when a function
8597 attribute (reentrant, etc) is used on a non-function or on a
8598 function but misplaced before the parameter list.
8600 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8602 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8625 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8627 Made the constant following the "interrupt" keyword optional. If
8628 omitted, the function will not automatically be given an entry
8629 in the interrupt vector table (similar to #pragma NOIV, but
8630 less syntacticly kludgy). The interrupt number is also now
8631 range checked. Also fixed a bug in the high order bit example

9072 condition and ignore commands.
9074 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9076 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9077 is in parts still quite out of date, I did changes as far as I felt makes sense
9078 for a non-native english speaker.
9079 Please feel free to add to the manual or to correct my changes.
9080 * doc/Makefile: undid touching the date of intermediate tex files.
9082 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9102 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9105 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9107 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9108 the regression tests I'm not brave enough to enable 245.b, 245.c
9109 * doc/sdccman.lyx: added latex preamble for hyperref package.
9110 Using pdflatex this will give you a hyperlinked pdf file with
9111 bookmarks. (prepend '%' before /usepackage if this breaks something)

9149 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9151 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9152 it can be defined with CFLAGS when running configure
9153 * src/SDCCmain.c: fixed compiling + linking with object files
9155 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9157 * configure.in: configure for pic16 port,
9158 added --disable-pic16-port
9159 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9160 * src/SDCCmain.c: linkOptions is changed to set *,
9161 added if/endif conditional macros to remove options help
9162 messages from optionsTable when a port is not configured, added
9163 support for the PIc16 port in the ports table, when executing
9164 the compiler with no port specified on command line, a default
9165 port is selected with the new macro DEFAULT_PORT which is
9166 defined in port.h, in setDefaultOptions() linkOptions is removed
9167 from initialization assignment, since now it is a set,
9168 parseCmdLine uses setParseWithComma for linkOptions, in
9169 linkEdit() linkOptions are accessed with new function indexSet()
9170 which returns the i'th item of a set variable. See SDCCset.c, in
9171 linkEdit() when calling buildCmdLine(), added linkOptions as
9172 last argument. Now users can pass arguments to gplink via the
9173 -Wl option, main() uses pic16glue() to glue up pic16 programs
9174 * src/SDCCpeeph.c: various changes to support pic16

9181 added macro DEFAULT_PORT
9182 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9183 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9185 * src/pic16/glue.c: commented out some error producing lines
9186 * src/pic16/main.c: __config directives are commented out to stop
9187 gpasm complaining and test the linkage with gplink, _linkCmd and
9188 _asmCmd changed to be more gplink and gpasm friendly
9189 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9190 produced an error when parsed, peep rule 12 is added to utilize
9191 movff, but it is commented out since the pCode does not support
9192 yet a command with 2 address arguments
9194 2003-05-18 <johan AT balder>
9196 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9197 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9216 on entry now. Add tbreak. Other enhancements and fixes for use
9219 2003-05-12 Borut Razem <borut.razem AT siol.net>
9221 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9223 2003-05-11 Borut Razem <borut.razem AT siol.net>
9225 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9226 the path of bin directory, so that PATH is the only env. variable, which has to be set
9227 in case of standard installation.
9228 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10257 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10259 * in \sdcc\as\mcs51\ changed these files in order to create an
10260 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10261 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10262 following files to include the previous two files: aslink.dsp,
10263 Makefile.aslink, Makefile.bcc, and Makefile.in.
10265 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10266 .adb instead of .cdb
10268 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10270 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10271 value from option --iram-size.
10273 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10275 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10278 2002-09-18 <wiml AT hhhh.org>
10280 * SDCClrange.h: exposed setFromRange() and setToRange()
10281 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10282 packRegsForAccUse() (bug 542397)
10283 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10284 multiple times and emitting the fetch operations more than once
10285 added aopGetUsesAcc() function to allow binary operators to
10286 fetch their operands in the correct order; made genMinus() emit
10287 compact code for X = LITERAL - Y
10289 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10290 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10291 sprintf() in line 1267.
10293 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10294 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10297 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10298 Changes to aslink (All the changes are marked with 'JCF'):
10300 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10303 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10304 area BSEG. Also moves, if possible, the DATA area down into the internal
10305 ram so more space is available.
10307 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10310 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10311 not bytes. Function summary() which creates a memory usage summary
10312 file with extension .mem. Reports of overlaping stack and small stack
10313 size. If the space for the stack is less than 16 bytes aslink trows a
10316 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10317 the 8051. Option 'y' for memory summary output file.
10319 Changes to sdcc (All the changes are marked with 'JCF'):
10321 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10323 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10324 overlaying area for it (uses RegBankUsed[4]).
10326 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10327 bank zero as used by default. By default aslink locates the stack
10328 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10329 the creation of the .mem file. Delegates the allocation of data area
10330 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10331 the begining of the stack area to aslink.
10333 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10334 glue() in SDCCglue.c creates an area for it.
10336 2002-09-03 Borut Razem <borut.razem AT siol.net>
10337 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10338 sdcc/src/pic/glue.c:
10339 introduced atexit() handler for teporay files removal in case of
10340 errors, assertions, ...
10342 2002-08-29 Borut Razem <borut.razem AT siol.net>
10343 * sdcc/support/cpp2/auto-host_vc_in.h:
10344 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10345 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10346 Maybe there is a similar problem with BORLANDC? It should be checked!
10348 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10349 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10350 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10351 was not executed, and the compiler (cl) launched a warning:
10352 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10354 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10355 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10357 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10366 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10367 - added Release configuration in VS projects
10368 - review of compiler an linker options
10369 - VC .exe files are generated in bin_vc directory, not to interfere
10370 with binaries generated from other projects (cygwin, mingw, bcc ...)
10372 * sdcc/src/yacc.dsp: added
10374 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10375 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10376 and insert the version number definitions from .version
10378 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10380 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10381 added - genarate auto-host.h using auto-host_vc_in.h as template
10384 removed from CVS, generated automatically
10386 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10387 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10389 2002-08-11 Borut Razem <borut.razem AT siol.net>
10390 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10392 2002-08-10 Borut Razem <borut.razem AT siol.net>
10393 * src/SDCCmain.c (main):
10394 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10395 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10396 The consequence was that some temporary files were not removed.
10399 unification of code in functions tempfilename() and tempfile():
10400 function tempnam() is defined in Visual Studio 6.0 and .NET
10402 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10404 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10405 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10406 - removed compiler command line option /WX: Treats all warnings as errors
10407 - update a list of source files, included into the project
10409 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10410 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10411 changed project type to Generic Project so that can be correcly converted to VS.NET project
10413 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10415 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10419 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10420 added return 0 statements after assert() to make compiler happy
10422 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10423 added newline in the def file to keep MSC compiler satisfied
10425 * sdcc/src/z80/gen.c:
10426 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10427 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10428 - solved MSC error in function aopDump()
10430 * sdcc_vc.h: define PREFIX as "\\sdcc"
10432 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10608 Previous fix was not good. basic blocks that have "break" or "return" are
10609 not really partof a loop , but live ranges used in these blocks should
