719 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
721 Enabled VPATH feature: changed nearly all Makefiles (149 files).
722 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
724 One basic decision: e.g. src/clean.mk includes further files. In order
725 to make this work there are two solutions:
726 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
727 run configure on them. This way they can use
728 'include $(srcdir)/port-clean.mk'
729 - always include clean.mk by the Makefile at the same level. To avoid
730 that `make clean` tries to include and build Makefile.dep the
731 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
732 implemented, because now even `make uninstall` doesn't create
733 Makefile.in. clean.mk could be eliminated by pasting it in
736 * debugger/mcs51/Makefile.in: build own objects from library sources
737 (SLIB, SDCC) in current directory
739 * configure, configure.in: renamed --disable-device-lib-build in
740 --disable-device-lib; added --enable-doc, the required tools are
741 searched by configure; added result message; the toolchain for the
742 belonging ports are now only built, if the port is enabled.
744 * support/regression/*: all output is written in directory gen, because
745 the fwk and ports directories don't livet in the build tree using vpath
747 * doc/sdccman.lyx: renamed --disable-device-lib-build to
748 --disable-device-lib, added --enable-doc, added section VPATH
750 * sim/ucsim/configure.in,
751 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
752 z80 are enabled by default
754 2006-04-24 Raphael Neider <rneider AT web.de>
756 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
757 to config word, "pic14_"-prefixed some extern functions

759 config word has been found
760 * src/pic/device.h: added prototypes
761 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

1011 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1013 * src/SDCCpeeph.c (operandsLiteral): new, added,

1025 implemented patch 1120823 Thanks to Willy De la Court (normal
1026 interrupts need an interrupt number now if they are made critical),
1027 and enabled nesting of critical functions though not for gbz80
1028 (genCritical, genEndCritical): added functions
1029 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1030 * src/z80/mappings.i: added "ei" to all mappings

1039 2006-03-16 Raphael Neider <rneider AT web.de>
1041 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1042 the left operand is shorter than the result (c* = lit-c* + int),
1044 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1047 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1049 * src/.version: increased version number to 2.5.5
1050 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1051 linking is done manually in pic16 port's _linkEdit,
1052 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1053 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1054 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1055 allocate asmop as AOP_ACC,
1056 (aopForRemat): added parameter 'bool result' in function declaration,
1057 (pic16_aopGet): return AOP_ACC when accessing WREG,
1058 (pic16_popGetTempReg): minor modification,
1059 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1060 'pic16_allocWithIdx',

1067 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1069 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1070 call to allocReg, not by manually allocating a new one,
1071 (pic16_assignRegisters): now before going through the register
1072 allocating functions mark all registers as free. This eliminates some
1073 side effects resulting from peephole parser done earlier in the backbone
1075 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1077 * src/SDCCicode.c (geniCodeLogic),

1096 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1097 (aopForSym, aopOp): increment asmop.allocated if reused,
1098 (freeAsmop): decrement asmop.allocated and check for zero instead of
1100 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1101 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1102 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1133 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1134 which dumps before the function entry point a data byte which represents
1135 the number of the local variables used by the specified function, added
1136 'xinst' for initial support for Extended Instruction Support,
1137 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1138 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1139 port->fun_prefix anymore (may change later),
1140 (genFunction, genEndFunction): do not store/restore local registers for
1141 _main (this should take care the --main-return command line option in
1143 (genOr): removed some legacy pic-port instructions,
1144 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1145 performing operations with SFR's causes data to be written more than
1146 once to each SFR. Perhaps SFRs should be handled in special cases...
1147 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1149 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1150 into account for stack starting position,

1152 --extended or -y for Extended Instruction Support,
1153 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1154 (deassignLRs): *** perhaps the most important change, old 'for' code
1155 (commented out for reference), didn't account for some registers which
1156 were left marked 'not free' after a pointer operation. The change
1157 reduces register usage a lot in some cases
1159 2006-03-04 Borut Razem <borut.razem AT siol.net>

3476 * src/SDCCdflow.c (computeDataFlow),
3478 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
3480 * src/SDCCcflow.c (*),
3482 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
3483 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3484 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3485 immedDom() returning wrong block; probably fixes bug #1160833)
3487 2005-03-20 Borut Razem <borut.razem AT siol.net>
3489 * support/scripts/inc2h.pl: WIN32 port
3491 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3493 * device/lib/makefile.in: added abs.c and labs.c
3495 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3497 * device/include/stdint.h: added
3498 * device/lib/abs.c: added
3499 * device/lib/labs.c: added
3500 * device/include/stdlib.h: added abs() and labs() prototypes
3501 * device/lib/libsdcc.lib: added abs and labs
3502 * device/include/float.h,
3503 * device/lib/_fsmul.c,
3504 * device/lib/printf_fast.c,
3505 * device/lib/printf_tiny.c: updated comments
3507 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3509 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3512 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3514 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3515 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3517 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3519 * device/lib/printf_large.c: removed inline assembly for portability and
3520 readability. Use printf_fast if speed or size are more important.
3521 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3522 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3524 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3526 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3527 prevent compiler warning
3529 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3531 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3532 moved to level 0 and declared as static. Also they are explicit
3533 placed in access bank. This was necessery because some times they
3534 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3535 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3536 optimizations. Currently only compare to unsigned char is implemented,
3537 * src/pic16/gen.c: added fReturnIdx array,
3538 * (struct resolvedIfx) is moved to gen.h and made public,
3539 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3540 * (aopForSym): added an optimization to directly store in stack of
3541 the operand of a SEND iCode,
3542 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3543 but as registers instead (AOP_REG) using the fReturnIdx array,
3544 * (pic16_freeAsmop): remove the freed register from the
3545 _G.sregsAlloc field,
3546 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3547 a compare of 'WREG',
3548 * (pic16_popGetTempRegCond): changed function prototype, now
3549 function takes also a bitVector argument v which holds the current
3550 set of registers that are allocated for stack access by aopForSym,
3551 registers allocated in aopForSym for accessing stack symbols are not
3552 any more part of the functions usedRegs field,
3553 * (genCall): some times aopOp is called for a stack variable to be
3554 send, aopForSym might perform the push, if this is true make sure
3555 that genCall doesn't push the variable twice by testing _G.resDirect,
3556 * (genFunction): changed testing for unspecified interrupt number
3557 from 256 to INTNO_UNSPEC,
3558 * modified selection scheme of frame pointer generation. Previously
3559 if function did use local registers a frame pointer was generated,
3560 now a frame pointer is generated only if function has arguments
3561 (that need PLUSW2 register access), or has stack arguments, or the
3562 compiler is not instructed to omit the frame pointer,
3563 * (genEndFunction): before restoring local registers that were saved
3564 in the function preamble, also restore the registers that *might*
3565 have been allocated for stack access,
3566 * (genRet): removed some old comments,
3567 * (genCmp, the active (RN's) version): added a call to the
3568 pic16_genCmp_special function to perform the compare with a more
3569 robust and optimized way,
3570 * (genInline): a feature has been added in inline code generation,
3571 which allows a wildcard variable substitution when writing inline
3572 assembly. Code is incomplete and experimental therefore undocumented,
3573 * (genCast): changed order of aopOp for result and right to allow
3574 aopForSym to directly load the result if possible,
3575 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3576 perform an optimized compare on some selected special occasions,
3577 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3578 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3579 generate an IVT any more,
3580 * src/pic16/main.c (pic16_optionsTable): added command line option
3582 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3583 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3585 * src/pic16/NOTES: Raphael Neider added in list of active developers
3586 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3587 jumptable_end to prevent bug #,
3588 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3589 inCond and outCond fields,
3590 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3591 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3592 turn off register spilling,
3593 * (packRegsForOneUse): synced with other ports' versions although it
3594 is not used currently,
3595 * (pic16_packRegisters): added an optimization while reading
3596 structure bitfields, some registers may be saved (malloc code is
3597 decreased by 80 bytes)
3599 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3601 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3602 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3603 this can be optimized more?
3605 2005-03-10 Raphael Neider <rneider AT web.de>
3607 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3608 genNearPointerGet): (hopefully) fixed access to bitfields via
3609 pointers (p->bitN = x; and x = p->bitN; failed)
3611 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3654 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3655 to keep the correct label reference count when adding/removing references
3656 to labels. A peephole file using this is appended to patch #1144962.

3799 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3800 this might fix SIGSEGVs on MinGW...

4243 Adding support for replacing ljmps with sjmps in jumptables
4244 generated for switch statements. For now you need to set the
4245 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4246 Now 4 algorithms for mcs51 jumptable generation are used:
4247 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4248 addresses loaded pc-relative for up to 112 cases and stack-pushing
4249 target addresses loaded with offset from dptr for up to 256 cases.

4279 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4281 * added libc directory. The current version of LibC contains string
4282 functions, ctype functions and macros and some functions of the
4283 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4284 be extensively tested in the future. Standard disclaimer here.
4285 Library is not automatically build yet. But one can build it by
4286 invoking 'make' inside the libc directory.

4297 * (pic16_storeForReturn): optimized return of 0,
4298 * (genCmp): experimental code for new genCmp which uses PIC18's
4299 special compare&skip instructions. Initial tests fail some times
4300 with variables grater than 1 byte in size, so new code is disabled,
4301 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4303 * (genCast): began a fix to optimize the casting of a bit to another
4304 bit, now assigning a bitfield to another bitfield will fail, sorry,

4312 * (isBankInstruction): modified to return 0 for no banking instruction,
4313 and 1 for banking instruction,
4314 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4315 caused stop processing pCodes after a inline assembly block,
4316 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4317 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4318 registers when it shouldn't,
4319 * src/pic16/ralloc.c (allocReg): add preliminary support for
4320 supporting a limited set of temporary registers,
4322 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4324 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4325 genDataPointerSet): ensure assignments always copy in MSB to LSB
4327 (loadRegFromAop): recognize CLRH optimization,
4328 (genFunction): optimize RECEIVE iCodes in reentrant functions
4330 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4332 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4341 * device/lib/_gptrget.c (_gptrget),
4342 * device/lib/_gptrgetc.c (_gptrgetc),

7327 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7329 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7330 loaded with the linker search paths (-L arguments) and the libraries
7331 to be linked with the current source (-l arguments). Changes
7332 currently will affect only the pic16 port.
7333 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7334 include path the port specific paths and port specific libraries,
7335 * gplink command now contains the $3 argument,
7336 * src/pic16/device.h,
7337 * src/pic16/device.c,: structure PIC_device is made public and

7353 Documenting changes from previous commits.
7354 * configure.in (version 1.56),
7355 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7356 when generating output files to configure the pic16 library,
7357 but now I've commented it out, since gputils aren't installed in the
7358 SF compile farm, so library won't compile
7360 * device/lib/Makefile.in (version 1.56): initially I've added in
7361 target 'all' the prerequestive 'model-pic16' so it compiled the
7362 pic16 library, but now I've commented it out for the same reasons
7364 * added targets 'model-pic16' and 'objects-pic16' to compile the
7366 * added target 'port-specific-objects-pic16' to handle the
7367 generated libraries and copy them into the build/ directory
7368 * added target 'clean-intermediate-pic16' to clean intermediate
7369 files into pic16 directory
7370 * in target 'installdirs' added line to create directory pic16 in
7371 the installation path

7374 added lines to copy all header files to installation path,
7375 * in target 'installdirs' added line create directory for pic16
7376 headers in the installation path

7392 option so that it actually works. Made it specific to the z80, since
7393 the gbz80 doesn't have these kinds of I/O ports.
7395 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7397 * device/include/z180.h,

7421 via literal number. The symbol is placed in the corresponding
7422 position of the data ram
7423 * (pic16_dump_section): relocatable and absolute uninitialized
7424 data are now emitted in sorted order to reduce section naming,
7425 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7426 weren't marked as being in the access bank,
7428 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7430 Added portion of GNU PIC Library under the directory
7431 device/include/pic16 and device/lib/pic16. These files
7432 contain the declarations of SFRs for the PIC18Fxx2 devices.
7433 The directory is initialized via configure from toplevel.

7462 * doc/sdccman.lyx: Moved and added some sections, small changes
7463 all over. Telling LaTeX to be less strict with word spacing
7464 to better keep the right margin. Changed some notes about
7465 maintainance of the ports in section 3.2.1 - is it OK like this?
7467 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7469 SDCC source changes:
7470 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

7504 UPPER for immediate operands,
7505 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7507 * src/pic16/peeph.def: all peepholes with movff are commented out,
7508 because there is a problem in the pcode peep optimizer,
7509 * src/pic16/ralloc.c: the register allocator can now reuse local

7602 include information about variables allocated to the overlay
7605 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7607 * as/mcs51/lkmain.c: Help about -Y option

7619 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7621 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7622 (default behaviour).
7624 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7626 A python script to validate compiler diagnostic messages. It can be
7627 used to verify that sdcc complains about bad c source code and
7628 gives a good location of the error.
7629 * support/valdiag/Makefile,
7630 * support/valdiag/valdiag.py,
7631 * support/valdiag/tests/*
7633 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7646 * src/common.h: added ifndef/define/endif macros
7647 around the header file.
7648 Bug reported from Jesus Calvino-Fraga
7650 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7652 * sdcc.spec: updated
7653 * device/include/Makefile.in: don't install CVS directories
7654 * device/lib/Makefile.in: added removal of CVS directories after install
7655 * doc/Makefile: fixed install, added local_icons
7656 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7657 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7658 * src/ds390/gen.c (genRightShift): fixed bug #870788
7659 * src/SDCCast.c (decorateType): fixed bug #870781
7661 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7663 PIC16 port related changes:
7664 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7665 added variable stackPos,
7667 * gen.c: genCall, assignResultValue: added support for
7668 pushing/retrieving function parameters to/from stack,
7669 genFunction,genEndFunction: setup stack frame for the
7671 genAddrOf: will be changed according to bug 863624
7673 * added files genutils.c and genutils.h which contain gen*
7674 debugged and optimised functions extracted from gen.c
7676 * glue.c: added variable 'externs' which holds extern symbols,
7677 pic16emitRegularMap: is modified to properly handle relocatable
7678 symbols under the new scheme,
7679 pic16createInterruptVect: is modified
7680 pic16printPublics: is modified to emit 'global' assembler directives,
7681 added pic16_printExterns to print extern symbols,
7682 pic16glue: initializes stack/frame pointer in the beginning of
7683 the assembly output. Temporary hack, will be corrected later,
7684 because gplink yet does not support stack and SDCC does not
7685 yet support a type of crt0.o object to create the final binary.
7687 * Removed many lines that contain 8051 legacy code.
7688 * The code is finally placed under a 'code' directive.
7689 * Added port specific options.
7691 * _process_pragma: simplified since now we do not need *special*
7692 include file to define SFR registers. But a separate header
7693 will be needed. This will be developed later.
7694 * _pic16_parseOptions: added, parses port specific options:
7695 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7696 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7697 --preplace-udata-with=
7699 * _pic16_setDefaultOptions: modified to initialize section names,
7700 but hack is temporarly out of order since it needs improvement.
7701 * _pic16_genAssemblerPreamble: configuration words are emitted by
7702 their address instead of their name. This part is incomplete and
7703 supports only the 18Fxx2 devices. Other devices will emit an error
7704 during assembly since they do not contain the same set of config
7706 * _pic16_genIVT: is modified,
7708 * pcode.c: added definitions for some hardware registers that are needed
7710 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7711 All PCI entries are updated. Now LFSR is supported.
7712 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7713 * added pic16_newpCodeOpLit2 to support instructions with
7714 two literal arguments
7715 * pic16_pCode2str: corrected code that emits assembler instructions
7716 with two literal operands and those that have an access bit modifier
7717 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7718 this fixes a bug which caused some labels to be lost, when an
7719 assembler directive was added, i.e. banksel,
7720 * pic16_FixRegisterBanking: improved logic that causes the insertion
7722 * InlineFunction: functions that are called once, are not any more
7723 inlined. This can be a port option in the future,
7725 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7727 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7728 hold the corresponding uninitialized symbols,
7729 * pic16_allocProcessorRegister: registers have explicit marked the
7731 * pic16_allocInternalRegister: registers are explicit marked as
7733 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7734 processing list, so bit registers were lost,
7737 * ralloc.h: added field 'accessBank' and original symbol operand
7738 in register definition,
7739 * removed the field isMapped from register definition,
7741 ** Several functions have been removed from various sources:
7742 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7743 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7744 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7745 pic16_assignRelocatableRegisters
7747 ** others have been introduced:
7748 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7749 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7751 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7753 * support/scripts/inc2h.pl: changed definition of BIT_AT
7754 to emit 'sbit at' instead of 'bit at'. This was a request.
7756 PIC16 port related preliminary changes:
7757 * gen.c: prefixed function popRegFromString with
7758 pic16_ and all references to it corrected
7759 * pcode.c: all pic16_pc_* hardware registers prefixed
7760 with underscore (_),
7761 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7762 * ralloc.c: newReg(): when register is REG_SFR then
7763 set address to rIdx,
7764 pic16_allocProcessorRegister(): marks register wasUsed=0
7765 pic16_writeUsedRegs(): added a call to assign processor
7766 registers via pic16_assignFixedRegisters
7768 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7770 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7771 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7772 variables in unused register banks. Also the SSEG is placed
7773 wherever there is enough space for it, and IDATA can be anywhere
7774 in internal RAM. For now compile using -Wl-Y[stack_size].
7775 The mem file is different for this option as well, since it
7776 makes no sense of talking about DSEG lenght.
7778 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7780 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7781 in certain cases, e.g. when ROM assignment, patch provided
7782 from Albert den Haan.
7784 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7927 * src/mcs51/peephole.def,
7928 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7929 (allows non-interrupt and interrupt code to safely compete for a resource

8807 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8808 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

8827 A few small changes that speed up the peephole optimizer.
8831 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8833 Try to make the peephole optimizer smarter by maintaining
8834 an association between the assembly source code and the
8835 iCodes that originated them. Put this information to use
8836 with a new peephole rule condition "notVolatile" so that
8837 the rules can be aggressive yet still safe.
8842 * src/mcs51/peeph.def
8844 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8848 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8849 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8850 if the left or right operand symbols have the accuse flag set.
8852 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8854 Changed the type of the result of the ! (NOT) operator to char;
8855 previously it returned the same type as the source. This allows
8856 us to eliminate all the genFloatNot functions (all of its target
8857 implementations were very buggy) since !float can use the same
8860 * src/SDCCicode.c (ast2iCode): ! returns char

8869 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8870 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8871 during interrupts. Ensure WSAVE is located at a shared bank address.
8872 2. Fixed page selection in some places
8873 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8874 the registers name strings.
8875 4. Fixed "signed / unsigned compare" compiler warnings.
8876 5. The PIC port manages its own allocation of the general purpose
8877 registers, but makes no attempt to reuse them. As a result when
8878 compiling it soon runs out of general purpose registers. Some
8879 additional code was added to the files pcode.c and device.c to walk
8880 through the function call tree and rename the registers so that they
8890 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8897 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8899 Made bitfield a distinct type from bit so that bitfields
8900 convert as per ANSI C and bits retain their traditional
8901 boolean style behaviour. Implemented bitfield support in
8909 * src/ds390/gen.c: bit v bitfield split
8910 * src/z80/gen.c: New support for bitfields
8911 * support/regression/tests/bitfields.c: reenabled z80,
8914 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8916 Rules 246.x, 247.x relate to bitfields, the others speed up
8917 access to xdata mapped I/O devices.
8919 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8921 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8923 Cleaned up genPackBits and genUnpackBits and added two helper

8933 Fixed bug #748310 (pointer to function type mishandled when the
8934 function name is omitted). Also fixed a SIGSEGV when a function
8935 attribute (reentrant, etc) is used on a non-function or on a
8936 function but misplaced before the parameter list.

8965 Made the constant following the "interrupt" keyword optional. If
8966 omitted, the function will not automatically be given an entry
8967 in the interrupt vector table (similar to #pragma NOIV, but
8968 less syntacticly kludgy). The interrupt number is also now
8969 range checked. Also fixed a bug in the high order bit example
8976 * support/Util/SDCCerr.c
8977 * support/Util/SDCCerr.h
8980 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8988 be re-activated by defining REDUCE_LITERALS)
8989 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8990 unsigned, but are signed by default
8991 * src/SDCCval.c (constVal): rearranged
8992 * src/SDCCval.c (valMod): preliminary fix
8993 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9502 the compiler with no port specified on command line, a default
9503 port is selected with the new macro DEFAULT_PORT which is
9504 defined in port.h, in setDefaultOptions() linkOptions is removed
9505 from initialization assignment, since now it is a set,
9506 parseCmdLine uses setParseWithComma for linkOptions, in
9507 linkEdit() linkOptions are accessed with new function indexSet()
9508 which returns the i'th item of a set variable. See SDCCset.c, in

10582 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10583 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10589 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10590 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10592 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10593 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10595 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10597 * in \sdcc\as\mcs51\ changed these files in order to create an
10598 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10599 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10600 following files to include the previous two files: aslink.dsp,
10601 Makefile.aslink, Makefile.bcc, and Makefile.in.
10603 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10604 .adb instead of .cdb
10606 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10608 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10609 value from option --iram-size.
10611 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10613 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10616 2002-09-18 <wiml AT hhhh.org>
10618 * SDCClrange.h: exposed setFromRange() and setToRange()
10619 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10620 packRegsForAccUse() (bug 542397)
10621 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10622 multiple times and emitting the fetch operations more than once
10623 added aopGetUsesAcc() function to allow binary operators to
10624 fetch their operands in the correct order; made genMinus() emit
10625 compact code for X = LITERAL - Y
10627 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10628 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10629 sprintf() in line 1267.
10631 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10632 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10635 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10636 Changes to aslink (All the changes are marked with 'JCF'):
10638 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10641 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10642 area BSEG. Also moves, if possible, the DATA area down into the internal
10643 ram so more space is available.
10645 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10648 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10649 not bytes. Function summary() which creates a memory usage summary
10650 file with extension .mem. Reports of overlaping stack and small stack
10651 size. If the space for the stack is less than 16 bytes aslink trows a
10654 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10655 the 8051. Option 'y' for memory summary output file.
10657 Changes to sdcc (All the changes are marked with 'JCF'):
10659 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10661 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10662 overlaying area for it (uses RegBankUsed[4]).
10664 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10665 bank zero as used by default. By default aslink locates the stack
10666 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10667 the creation of the .mem file. Delegates the allocation of data area
10668 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10669 the begining of the stack area to aslink.
10671 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10672 glue() in SDCCglue.c creates an area for it.
10674 2002-09-03 Borut Razem <borut.razem AT siol.net>
10675 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10676 sdcc/src/pic/glue.c:
10677 introduced atexit() handler for teporay files removal in case of
10678 errors, assertions, ...
10680 2002-08-29 Borut Razem <borut.razem AT siol.net>
10681 * sdcc/support/cpp2/auto-host_vc_in.h:
10682 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10683 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10684 Maybe there is a similar problem with BORLANDC? It should be checked!
10686 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10687 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10688 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10689 was not executed, and the compiler (cl) launched a warning:
10690 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10692 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10693 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10695 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10696 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10698 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10699 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10700 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10701 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10702 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10703 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10704 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10705 - added Release configuration in VS projects
10706 - review of compiler an linker options
10707 - VC .exe files are generated in bin_vc directory, not to interfere
10708 with binaries generated from other projects (cygwin, mingw, bcc ...)
10710 * sdcc/src/yacc.dsp: added
10712 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10713 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10714 and insert the version number definitions from .version
10716 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10718 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10719 added - genarate auto-host.h using auto-host_vc_in.h as template
10722 removed from CVS, generated automatically
10724 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10725 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10727 2002-08-11 Borut Razem <borut.razem AT siol.net>
10728 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10730 2002-08-10 Borut Razem <borut.razem AT siol.net>
10731 * src/SDCCmain.c (main):
10732 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10733 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10734 The consequence was that some temporary files were not removed.
10737 unification of code in functions tempfilename() and tempfile():
10738 function tempnam() is defined in Visual Studio 6.0 and .NET
10740 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10742 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10743 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10744 - removed compiler command line option /WX: Treats all warnings as errors
10745 - update a list of source files, included into the project
10747 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10748 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10749 changed project type to Generic Project so that can be correcly converted to VS.NET project
10751 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10753 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10755 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10757 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10758 added return 0 statements after assert() to make compiler happy
10760 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10761 added newline in the def file to keep MSC compiler satisfied
10763 * sdcc/src/z80/gen.c:
10764 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10765 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10766 - solved MSC error in function aopDump()
10768 * sdcc_vc.h: define PREFIX as "\\sdcc"
10770 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10771 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10773 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10774 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10775 - Rewrote the register banking algorithm.
10776 - Added pCode live-range analysis to registers (for now, only non-used and
10777 singly-used registers optimized away)
10779 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10781 * 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.
10783 2002-05-10 Scott Dattalo <scott AT dattalo.com>
10784 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

10796 2002-04-15 Michael Hope <michaelh AT vroom>
10798 * device/lib/z80/printf.c (sprintf): Added.
10800 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10802 * src/z80/peeph.def: Added transpose redundent load rule.
