723 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
725 Enabled VPATH feature: changed nearly all Makefiles (149 files).
726 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
728 One basic decision: e.g. src/clean.mk includes further files. In order
729 to make this work there are two solutions:
730 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
731 run configure on them. This way they can use
732 'include $(srcdir)/port-clean.mk'
733 - always include clean.mk by the Makefile at the same level. To avoid
734 that `make clean` tries to include and build Makefile.dep the
735 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
736 implemented, because now even `make uninstall` doesn't create
737 Makefile.in. clean.mk could be eliminated by pasting it in
740 * debugger/mcs51/Makefile.in: build own objects from library sources
741 (SLIB, SDCC) in current directory
743 * configure, configure.in: renamed --disable-device-lib-build in
744 --disable-device-lib; added --enable-doc, the required tools are
745 searched by configure; added result message; the toolchain for the
746 belonging ports are now only built, if the port is enabled.
748 * support/regression/*: all output is written in directory gen, because
749 the fwk and ports directories don't livet in the build tree using vpath
751 * doc/sdccman.lyx: renamed --disable-device-lib-build to
752 --disable-device-lib, added --enable-doc, added section VPATH
754 * sim/ucsim/configure.in,
755 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
756 z80 are enabled by default
758 2006-04-24 Raphael Neider <rneider AT web.de>
760 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
761 to config word, "pic14_"-prefixed some extern functions
762 (pic14_emitConfigWord): emit __config directive(s) if assignment to
763 config word has been found
764 * src/pic/device.h: added prototypes
765 * src/pic/pcode.c: added "pic14_"-prefix where needed

768 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1006 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1008 * src/mcs51/gen.c (genCall): fixed bug 1457608
1010 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1012 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

1015 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1017 * src/SDCCpeeph.c (operandsLiteral): new, added,

1029 implemented patch 1120823 Thanks to Willy De la Court (normal
1030 interrupts need an interrupt number now if they are made critical),
1031 and enabled nesting of critical functions though not for gbz80
1032 (genCritical, genEndCritical): added functions
1033 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1034 * src/z80/mappings.i: added "ei" to all mappings
1036 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1038 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1039 submitted by the Debian SDCC maintainer Aurelien Jarno:
1040 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1041 archive with gcc 4.1 on mips and wrote the patch"
1043 2006-03-16 Raphael Neider <rneider AT web.de>
1045 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1046 the left operand is shorter than the result (c* = lit-c* + int),
1048 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1051 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1053 * src/.version: increased version number to 2.5.5
1054 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1055 linking is done manually in pic16 port's _linkEdit,
1056 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1057 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1058 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1059 allocate asmop as AOP_ACC,
1060 (aopForRemat): added parameter 'bool result' in function declaration,
1061 (pic16_aopGet): return AOP_ACC when accessing WREG,
1062 (pic16_popGetTempReg): minor modification,
1063 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1064 'pic16_allocWithIdx',
1065 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1066 calling function in absolute addresses,
1067 (genAssign): take into account AOP_ACC asmop,
1068 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1069 * src/pic16/pcoderegs.c: some debug functions and lines added,

1071 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1073 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1074 call to allocReg, not by manually allocating a new one,
1075 (pic16_assignRegisters): now before going through the register
1076 allocating functions mark all registers as free. This eliminates some
1077 side effects resulting from peephole parser done earlier in the backbone
1079 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1081 * src/SDCCicode.c (geniCodeLogic),

1100 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1101 (aopForSym, aopOp): increment asmop.allocated if reused,
1102 (freeAsmop): decrement asmop.allocated and check for zero instead of
1104 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1105 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1106 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1129 2006-03-06 Borut Razem <borut.razem AT siol.net>
1131 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1132 made the linker quiet
1134 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1136 * src/pic16/gen.c (genPcall): fixed bug #1443644
1137 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1138 which dumps before the function entry point a data byte which represents
1139 the number of the local variables used by the specified function, added
1140 'xinst' for initial support for Extended Instruction Support,
1141 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1142 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1143 port->fun_prefix anymore (may change later),
1144 (genFunction, genEndFunction): do not store/restore local registers for
1145 _main (this should take care the --main-return command line option in
1147 (genOr): removed some legacy pic-port instructions,
1148 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1149 performing operations with SFR's causes data to be written more than
1150 once to each SFR. Perhaps SFRs should be handled in special cases...
1151 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1153 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1154 into account for stack starting position,
1155 (struct OPTIONS pic16_optionsTable): added command line argument
1156 --extended or -y for Extended Instruction Support,
1157 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1158 (deassignLRs): *** perhaps the most important change, old 'for' code
1159 (commented out for reference), didn't account for some registers which
1160 were left marked 'not free' after a pointer operation. The change
1161 reduces register usage a lot in some cases
1163 2006-03-04 Borut Razem <borut.razem AT siol.net>
1165 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3475 * src/z80/ralloc.c (z80_assignRegisters),
3477 * src/SDCCopt.c (eBBlockFromiCode, replaceRegEqv, killDeadCode),
3478 * src/SDCCcse.c (ifxOptimize, cseBBlock, cseAllBlocks),
3480 * src/SDCCdflow.c (computeDataFlow),
3482 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
3484 * src/SDCCcflow.c (*),
3486 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
3487 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3488 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3489 immedDom() returning wrong block; probably fixes bug #1160833)
3491 2005-03-20 Borut Razem <borut.razem AT siol.net>
3493 * support/scripts/inc2h.pl: WIN32 port
3495 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3497 * device/lib/makefile.in: added abs.c and labs.c
3499 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3501 * device/include/stdint.h: added
3502 * device/lib/abs.c: added
3503 * device/lib/labs.c: added
3504 * device/include/stdlib.h: added abs() and labs() prototypes
3505 * device/lib/libsdcc.lib: added abs and labs
3506 * device/include/float.h,
3507 * device/lib/_fsmul.c,
3508 * device/lib/printf_fast.c,
3509 * device/lib/printf_tiny.c: updated comments
3511 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3513 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3516 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3518 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3519 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3521 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3523 * device/lib/printf_large.c: removed inline assembly for portability and
3524 readability. Use printf_fast if speed or size are more important.
3525 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3526 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3528 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3530 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3531 prevent compiler warning
3533 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3535 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3536 moved to level 0 and declared as static. Also they are explicit
3537 placed in access bank. This was necessery because some times they
3538 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3539 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3540 optimizations. Currently only compare to unsigned char is implemented,
3541 * src/pic16/gen.c: added fReturnIdx array,
3542 * (struct resolvedIfx) is moved to gen.h and made public,
3543 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3544 * (aopForSym): added an optimization to directly store in stack of
3545 the operand of a SEND iCode,
3546 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3547 but as registers instead (AOP_REG) using the fReturnIdx array,
3548 * (pic16_freeAsmop): remove the freed register from the
3549 _G.sregsAlloc field,
3550 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3551 a compare of 'WREG',
3552 * (pic16_popGetTempRegCond): changed function prototype, now
3553 function takes also a bitVector argument v which holds the current
3554 set of registers that are allocated for stack access by aopForSym,
3555 registers allocated in aopForSym for accessing stack symbols are not
3556 any more part of the functions usedRegs field,
3557 * (genCall): some times aopOp is called for a stack variable to be
3558 send, aopForSym might perform the push, if this is true make sure
3559 that genCall doesn't push the variable twice by testing _G.resDirect,
3560 * (genFunction): changed testing for unspecified interrupt number
3561 from 256 to INTNO_UNSPEC,
3562 * modified selection scheme of frame pointer generation. Previously
3563 if function did use local registers a frame pointer was generated,
3564 now a frame pointer is generated only if function has arguments
3565 (that need PLUSW2 register access), or has stack arguments, or the
3566 compiler is not instructed to omit the frame pointer,
3567 * (genEndFunction): before restoring local registers that were saved
3568 in the function preamble, also restore the registers that *might*
3569 have been allocated for stack access,
3570 * (genRet): removed some old comments,
3571 * (genCmp, the active (RN's) version): added a call to the
3572 pic16_genCmp_special function to perform the compare with a more
3573 robust and optimized way,
3574 * (genInline): a feature has been added in inline code generation,
3575 which allows a wildcard variable substitution when writing inline
3576 assembly. Code is incomplete and experimental therefore undocumented,
3577 * (genCast): changed order of aopOp for result and right to allow
3578 aopForSym to directly load the result if possible,
3579 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3580 perform an optimized compare on some selected special occasions,
3581 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3582 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3583 generate an IVT any more,
3584 * src/pic16/main.c (pic16_optionsTable): added command line option
3586 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3587 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3589 * src/pic16/NOTES: Raphael Neider added in list of active developers
3590 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3591 jumptable_end to prevent bug #,
3592 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3593 inCond and outCond fields,
3594 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3595 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3596 turn off register spilling,
3597 * (packRegsForOneUse): synced with other ports' versions although it
3598 is not used currently,
3599 * (pic16_packRegisters): added an optimization while reading
3600 structure bitfields, some registers may be saved (malloc code is
3601 decreased by 80 bytes)
3603 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3605 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3606 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3607 this can be optimized more?
3609 2005-03-10 Raphael Neider <rneider AT web.de>
3611 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3612 genNearPointerGet): (hopefully) fixed access to bitfields via
3613 pointers (p->bitN = x; and x = p->bitN; failed)
3615 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3658 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3659 to keep the correct label reference count when adding/removing references
3660 to labels. A peephole file using this is appended to patch #1144962.

3803 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3804 this might fix SIGSEGVs on MinGW...
3805 * src/SDCCopt.c (killDeadCode): restored original behaviour
3806 (volatile operands might get thrown away though)

3893 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
3894 used uninitialized in some cases)

4249 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4250 Now 4 algorithms for mcs51 jumptable generation are used:
4251 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4283 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4285 * added libc directory. The current version of LibC contains string
4286 functions, ctype functions and macros and some functions of the
4287 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4288 be extensively tested in the future. Standard disclaimer here.
4289 Library is not automatically build yet. But one can build it by

4301 * (pic16_storeForReturn): optimized return of 0,
4302 * (genCmp): experimental code for new genCmp which uses PIC18's
4303 special compare&skip instructions. Initial tests fail some times
4304 with variables grater than 1 byte in size, so new code is disabled,
4305 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4307 * (genCast): began a fix to optimize the casting of a bit to another
4308 bit, now assigning a bitfield to another bitfield will fail, sorry,

4317 and 1 for banking instruction,
4318 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4319 caused stop processing pCodes after a inline assembly block,

4322 registers when it shouldn't,
4323 * src/pic16/ralloc.c (allocReg): add preliminary support for
4324 supporting a limited set of temporary registers,
4326 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4332 (genFunction): optimize RECEIVE iCodes in reentrant functions
4334 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7331 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7333 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7334 loaded with the linker search paths (-L arguments) and the libraries
7335 to be linked with the current source (-l arguments). Changes
7336 currently will affect only the pic16 port.
7337 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7338 include path the port specific paths and port specific libraries,
7339 * gplink command now contains the $3 argument,
7340 * src/pic16/device.h,
7341 * src/pic16/device.c,: structure PIC_device is made public and
7342 renamed to PIC16_device, the same for variable Pics which is renamed

7357 Documenting changes from previous commits.
7358 * configure.in (version 1.56),
7359 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7360 when generating output files to configure the pic16 library,
7361 but now I've commented it out, since gputils aren't installed in the
7362 SF compile farm, so library won't compile
7364 * device/lib/Makefile.in (version 1.56): initially I've added in
7365 target 'all' the prerequestive 'model-pic16' so it compiled the
7366 pic16 library, but now I've commented it out for the same reasons
7368 * added targets 'model-pic16' and 'objects-pic16' to compile the
7370 * added target 'port-specific-objects-pic16' to handle the
7371 generated libraries and copy them into the build/ directory
7372 * added target 'clean-intermediate-pic16' to clean intermediate
7373 files into pic16 directory
7374 * in target 'installdirs' added line to create directory pic16 in
7375 the installation path
7377 * device/include/Makefile.in (version 1.11): in target 'install'
7378 added lines to copy all header files to installation path,
7379 * in target 'installdirs' added line create directory for pic16
7380 headers in the installation path

7395 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7396 option so that it actually works. Made it specific to the z80, since
7397 the gbz80 doesn't have these kinds of I/O ports.
7399 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7401 * device/include/z180.h,

7425 via literal number. The symbol is placed in the corresponding
7426 position of the data ram
7427 * (pic16_dump_section): relocatable and absolute uninitialized
7428 data are now emitted in sorted order to reduce section naming,
7429 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7430 weren't marked as being in the access bank,
7432 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7434 Added portion of GNU PIC Library under the directory
7435 device/include/pic16 and device/lib/pic16. These files
7436 contain the declarations of SFRs for the PIC18Fxx2 devices.
7437 The directory is initialized via configure from toplevel.
7439 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7441 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7448 2004-01-12 Borut Razem <borut.razem AT siol.net>
7450 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
7451 doc/sdccman.lyx: upper case pragmas are deprecated
7453 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7455 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results

7466 * doc/sdccman.lyx: Moved and added some sections, small changes
7467 all over. Telling LaTeX to be less strict with word spacing
7468 to better keep the right margin. Changed some notes about
7469 maintainance of the ports in section 3.2.1 - is it OK like this?
7471 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7473 SDCC source changes:
7474 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7509 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7511 * src/pic16/peeph.def: all peepholes with movff are commented out,
7512 because there is a problem in the pcode peep optimizer,
7513 * src/pic16/ralloc.c: the register allocator can now reuse local

7606 include information about variables allocated to the overlay
7609 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7611 * as/mcs51/lkmain.c: Help about -Y option

7623 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7625 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7626 (default behaviour).
7628 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7630 A python script to validate compiler diagnostic messages. It can be
7631 used to verify that sdcc complains about bad c source code and
7632 gives a good location of the error.
7633 * support/valdiag/Makefile,
7634 * support/valdiag/valdiag.py,
7635 * support/valdiag/tests/*

7651 around the header file.
7652 Bug reported from Jesus Calvino-Fraga
7654 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7656 * sdcc.spec: updated
7657 * device/include/Makefile.in: don't install CVS directories
7658 * device/lib/Makefile.in: added removal of CVS directories after install
7659 * doc/Makefile: fixed install, added local_icons
7660 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7661 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7662 * src/ds390/gen.c (genRightShift): fixed bug #870788
7663 * src/SDCCast.c (decorateType): fixed bug #870781
7665 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7667 PIC16 port related changes:
7668 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7669 added variable stackPos,
7671 * gen.c: genCall, assignResultValue: added support for
7672 pushing/retrieving function parameters to/from stack,
7673 genFunction,genEndFunction: setup stack frame for the
7675 genAddrOf: will be changed according to bug 863624
7677 * added files genutils.c and genutils.h which contain gen*
7678 debugged and optimised functions extracted from gen.c
7680 * glue.c: added variable 'externs' which holds extern symbols,
7681 pic16emitRegularMap: is modified to properly handle relocatable
7682 symbols under the new scheme,
7683 pic16createInterruptVect: is modified
7684 pic16printPublics: is modified to emit 'global' assembler directives,
7685 added pic16_printExterns to print extern symbols,
7686 pic16glue: initializes stack/frame pointer in the beginning of
7687 the assembly output. Temporary hack, will be corrected later,
7688 because gplink yet does not support stack and SDCC does not
7689 yet support a type of crt0.o object to create the final binary.
7691 * Removed many lines that contain 8051 legacy code.
7692 * The code is finally placed under a 'code' directive.
7693 * Added port specific options.
7695 * _process_pragma: simplified since now we do not need *special*
7696 include file to define SFR registers. But a separate header
7697 will be needed. This will be developed later.
7698 * _pic16_parseOptions: added, parses port specific options:
7699 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7700 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7701 --preplace-udata-with=
7703 * _pic16_setDefaultOptions: modified to initialize section names,
7704 but hack is temporarly out of order since it needs improvement.
7705 * _pic16_genAssemblerPreamble: configuration words are emitted by
7706 their address instead of their name. This part is incomplete and
7707 supports only the 18Fxx2 devices. Other devices will emit an error
7708 during assembly since they do not contain the same set of config
7710 * _pic16_genIVT: is modified,
7712 * pcode.c: added definitions for some hardware registers that are needed
7714 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7715 All PCI entries are updated. Now LFSR is supported.
7716 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7717 * added pic16_newpCodeOpLit2 to support instructions with
7718 two literal arguments
7719 * pic16_pCode2str: corrected code that emits assembler instructions
7720 with two literal operands and those that have an access bit modifier
7721 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7722 this fixes a bug which caused some labels to be lost, when an
7723 assembler directive was added, i.e. banksel,
7724 * pic16_FixRegisterBanking: improved logic that causes the insertion
7726 * InlineFunction: functions that are called once, are not any more
7727 inlined. This can be a port option in the future,
7729 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7731 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7732 hold the corresponding uninitialized symbols,
7733 * pic16_allocProcessorRegister: registers have explicit marked the
7735 * pic16_allocInternalRegister: registers are explicit marked as
7737 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7738 processing list, so bit registers were lost,
7741 * ralloc.h: added field 'accessBank' and original symbol operand
7742 in register definition,
7743 * removed the field isMapped from register definition,
7745 ** Several functions have been removed from various sources:
7746 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7747 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7748 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7749 pic16_assignRelocatableRegisters
7751 ** others have been introduced:
7752 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7753 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7755 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7757 * support/scripts/inc2h.pl: changed definition of BIT_AT
7758 to emit 'sbit at' instead of 'bit at'. This was a request.
7760 PIC16 port related preliminary changes:
7761 * gen.c: prefixed function popRegFromString with
7762 pic16_ and all references to it corrected
7763 * pcode.c: all pic16_pc_* hardware registers prefixed
7764 with underscore (_),
7765 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7766 * ralloc.c: newReg(): when register is REG_SFR then
7767 set address to rIdx,
7768 pic16_allocProcessorRegister(): marks register wasUsed=0
7769 pic16_writeUsedRegs(): added a call to assign processor
7770 registers via pic16_assignFixedRegisters
7772 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7774 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7775 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7776 variables in unused register banks. Also the SSEG is placed
7777 wherever there is enough space for it, and IDATA can be anywhere
7778 in internal RAM. For now compile using -Wl-Y[stack_size].
7779 The mem file is different for this option as well, since it
7780 makes no sense of talking about DSEG lenght.
7782 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7784 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7785 in certain cases, e.g. when ROM assignment, patch provided
7786 from Albert den Haan.
7788 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7931 * src/mcs51/peephole.def,
7932 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8811 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8812 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

8831 A few small changes that speed up the peephole optimizer.
8835 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8837 Try to make the peephole optimizer smarter by maintaining
8838 an association between the assembly source code and the
8839 iCodes that originated them. Put this information to use
8840 with a new peephole rule condition "notVolatile" so that
8841 the rules can be aggressive yet still safe.
8846 * src/mcs51/peeph.def
8848 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8852 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8853 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8854 if the left or right operand symbols have the accuse flag set.
8856 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8858 Changed the type of the result of the ! (NOT) operator to char;
8859 previously it returned the same type as the source. This allows
8860 us to eliminate all the genFloatNot functions (all of its target
8861 implementations were very buggy) since !float can use the same
8864 * src/SDCCicode.c (ast2iCode): ! returns char

8873 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8874 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8875 during interrupts. Ensure WSAVE is located at a shared bank address.
8876 2. Fixed page selection in some places
8877 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8878 the registers name strings.
8879 4. Fixed "signed / unsigned compare" compiler warnings.
8880 5. The PIC port manages its own allocation of the general purpose
8881 registers, but makes no attempt to reuse them. As a result when
8882 compiling it soon runs out of general purpose registers. Some
8883 additional code was added to the files pcode.c and device.c to walk
8884 through the function call tree and rename the registers so that they
8894 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8901 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8903 Made bitfield a distinct type from bit so that bitfields
8904 convert as per ANSI C and bits retain their traditional
8905 boolean style behaviour. Implemented bitfield support in
8913 * src/ds390/gen.c: bit v bitfield split
8914 * src/z80/gen.c: New support for bitfields
8915 * support/regression/tests/bitfields.c: reenabled z80,
8918 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8920 Rules 246.x, 247.x relate to bitfields, the others speed up
8921 access to xdata mapped I/O devices.
8923 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8925 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8927 Cleaned up genPackBits and genUnpackBits and added two helper

8937 Fixed bug #748310 (pointer to function type mishandled when the
8938 function name is omitted). Also fixed a SIGSEGV when a function
8939 attribute (reentrant, etc) is used on a non-function or on a
8940 function but misplaced before the parameter list.

8969 Made the constant following the "interrupt" keyword optional. If
8970 omitted, the function will not automatically be given an entry
8971 in the interrupt vector table (similar to #pragma NOIV, but
8972 less syntacticly kludgy). The interrupt number is also now
8973 range checked. Also fixed a bug in the high order bit example
8980 * support/Util/SDCCerr.c
8981 * support/Util/SDCCerr.h
8984 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8994 unsigned, but are signed by default
8995 * src/SDCCval.c (constVal): rearranged
8996 * src/SDCCval.c (valMod): preliminary fix
8997 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9041 * src/SDCCval.c (valDiv, valMod): fixed signdness
9042 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9043 signedness of modulo, left and right shift

9506 the compiler with no port specified on command line, a default
9507 port is selected with the new macro DEFAULT_PORT which is
9508 defined in port.h, in setDefaultOptions() linkOptions is removed
9509 from initialization assignment, since now it is a set,
9510 parseCmdLine uses setParseWithComma for linkOptions, in
9511 linkEdit() linkOptions are accessed with new function indexSet()
9512 which returns the i'th item of a set variable. See SDCCset.c, in

10586 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10587 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10593 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10594 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10596 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10597 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10599 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10601 * in \sdcc\as\mcs51\ changed these files in order to create an
10602 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10603 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10604 following files to include the previous two files: aslink.dsp,
10605 Makefile.aslink, Makefile.bcc, and Makefile.in.
10607 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10608 .adb instead of .cdb
10610 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10612 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10613 value from option --iram-size.
10615 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10617 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10620 2002-09-18 <wiml AT hhhh.org>
10622 * SDCClrange.h: exposed setFromRange() and setToRange()
10623 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10624 packRegsForAccUse() (bug 542397)
10625 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10626 multiple times and emitting the fetch operations more than once
10627 added aopGetUsesAcc() function to allow binary operators to
10628 fetch their operands in the correct order; made genMinus() emit
10629 compact code for X = LITERAL - Y
10631 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10632 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10633 sprintf() in line 1267.
10635 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10636 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10639 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10640 Changes to aslink (All the changes are marked with 'JCF'):
10642 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10645 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10646 area BSEG. Also moves, if possible, the DATA area down into the internal
10647 ram so more space is available.
10649 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10652 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10653 not bytes. Function summary() which creates a memory usage summary
10654 file with extension .mem. Reports of overlaping stack and small stack
10655 size. If the space for the stack is less than 16 bytes aslink trows a
10658 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10659 the 8051. Option 'y' for memory summary output file.
10661 Changes to sdcc (All the changes are marked with 'JCF'):
10663 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10665 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10666 overlaying area for it (uses RegBankUsed[4]).
10668 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10669 bank zero as used by default. By default aslink locates the stack
10670 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10671 the creation of the .mem file. Delegates the allocation of data area
10672 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10673 the begining of the stack area to aslink.
10675 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10676 glue() in SDCCglue.c creates an area for it.
10678 2002-09-03 Borut Razem <borut.razem AT siol.net>
10679 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10680 sdcc/src/pic/glue.c:
10681 introduced atexit() handler for teporay files removal in case of
10682 errors, assertions, ...
10684 2002-08-29 Borut Razem <borut.razem AT siol.net>
10685 * sdcc/support/cpp2/auto-host_vc_in.h:
10686 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10687 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10688 Maybe there is a similar problem with BORLANDC? It should be checked!
10690 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10691 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10692 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10693 was not executed, and the compiler (cl) launched a warning:
10694 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10696 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10697 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10699 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10700 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10702 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10703 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10704 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10705 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10706 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10707 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10708 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10709 - added Release configuration in VS projects
10710 - review of compiler an linker options
10711 - VC .exe files are generated in bin_vc directory, not to interfere
10712 with binaries generated from other projects (cygwin, mingw, bcc ...)
10714 * sdcc/src/yacc.dsp: added
10716 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10717 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10718 and insert the version number definitions from .version
10720 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10722 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10723 added - genarate auto-host.h using auto-host_vc_in.h as template
10726 removed from CVS, generated automatically
10728 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10729 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10731 2002-08-11 Borut Razem <borut.razem AT siol.net>
10732 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10734 2002-08-10 Borut Razem <borut.razem AT siol.net>
10735 * src/SDCCmain.c (main):
10736 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10737 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10738 The consequence was that some temporary files were not removed.
10741 unification of code in functions tempfilename() and tempfile():
10742 function tempnam() is defined in Visual Studio 6.0 and .NET
10744 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10746 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10747 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10748 - removed compiler command line option /WX: Treats all warnings as errors
10749 - update a list of source files, included into the project
10751 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10752 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10753 changed project type to Generic Project so that can be correcly converted to VS.NET project
10755 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10757 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10759 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10761 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10762 added return 0 statements after assert() to make compiler happy
10764 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10765 added newline in the def file to keep MSC compiler satisfied
10767 * sdcc/src/z80/gen.c:
10768 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10769 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10770 - solved MSC error in function aopDump()
10772 * sdcc_vc.h: define PREFIX as "\\sdcc"
10774 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10775 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10777 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10778 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10779 - Rewrote the register banking algorithm.
10780 - Added pCode live-range analysis to registers (for now, only non-used and
10781 singly-used registers optimized away)
10783 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10785 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
10787 2002-05-10 Scott Dattalo <scott AT dattalo.com>
10788 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
10790 2002-04-22 Michael Hope <michaelh AT vroom>

10800 2002-04-15 Michael Hope <michaelh AT vroom>
10802 * device/lib/z80/printf.c (sprintf): Added.
10804 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10806 * src/z80/peeph.def: Added transpose redundent load rule.
