799 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
801 Enabled VPATH feature: changed nearly all Makefiles (149 files).
802 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
804 One basic decision: e.g. src/clean.mk includes further files. In order
805 to make this work there are two solutions:
806 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
807 run configure on them. This way they can use
808 'include $(srcdir)/port-clean.mk'
809 - always include clean.mk by the Makefile at the same level. To avoid
810 that `make clean` tries to include and build Makefile.dep the
811 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
812 implemented, because now even `make uninstall` doesn't create
813 Makefile.in. clean.mk could be eliminated by pasting it in
816 * debugger/mcs51/Makefile.in: build own objects from library sources
817 (SLIB, SDCC) in current directory
819 * configure, configure.in: renamed --disable-device-lib-build in
820 --disable-device-lib; added --enable-doc, the required tools are
821 searched by configure; added result message; the toolchain for the
822 belonging ports are now only built, if the port is enabled.
824 * support/regression/*: all output is written in directory gen, because
825 the fwk and ports directories don't livet in the build tree using vpath
827 * doc/sdccman.lyx: renamed --disable-device-lib-build to
828 --disable-device-lib, added --enable-doc, added section VPATH
830 * sim/ucsim/configure.in,
831 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
832 z80 are enabled by default
834 2006-04-24 Raphael Neider <rneider AT web.de>
836 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
837 to config word, "pic14_"-prefixed some extern functions
838 (pic14_emitConfigWord): emit __config directive(s) if assignment to
839 config word has been found
840 * src/pic/device.h: added prototypes
841 * src/pic/pcode.c: added "pic14_"-prefix where needed
842 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
844 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
846 (pic14emitRegularMap): ignore config words,
847 (pic14createInterruptVect): moved generating __config directives away

858 fixes #1469504 and #1474602,
859 (pCodeRegOptimizeRegUsage): fixed typo in comment

863 * device/examples/main8051.c: deleted - it was removed from CVS

1105 implemented patch 1120823 Thanks to Willy De la Court (normal
1106 interrupts need an interrupt number now if they are made critical),
1107 and enabled nesting of critical functions though not for gbz80
1108 (genCritical, genEndCritical): added functions
1109 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1110 * src/z80/mappings.i: added "ei" to all mappings

1122 the left operand is shorter than the result (c* = lit-c* + int),
1124 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1127 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1129 * src/.version: increased version number to 2.5.5
1130 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1131 linking is done manually in pic16 port's _linkEdit,
1132 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1133 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1134 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1135 allocate asmop as AOP_ACC,
1136 (aopForRemat): added parameter 'bool result' in function declaration,
1137 (pic16_aopGet): return AOP_ACC when accessing WREG,
1138 (pic16_popGetTempReg): minor modification,

1149 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1150 call to allocReg, not by manually allocating a new one,
1151 (pic16_assignRegisters): now before going through the register
1152 allocating functions mark all registers as free. This eliminates some
1153 side effects resulting from peephole parser done earlier in the backbone
1155 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1213 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1214 which dumps before the function entry point a data byte which represents
1215 the number of the local variables used by the specified function, added
1216 'xinst' for initial support for Extended Instruction Support,
1217 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1218 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1219 port->fun_prefix anymore (may change later),
1220 (genFunction, genEndFunction): do not store/restore local registers for
1221 _main (this should take care the --main-return command line option in
1223 (genOr): removed some legacy pic-port instructions,
1224 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1225 performing operations with SFR's causes data to be written more than
1226 once to each SFR. Perhaps SFRs should be handled in special cases...
1227 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1229 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1230 into account for stack starting position,

1232 --extended or -y for Extended Instruction Support,
1233 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1234 (deassignLRs): *** perhaps the most important change, old 'for' code
1235 (commented out for reference), didn't account for some registers which
1236 were left marked 'not free' after a pointer operation. The change
1237 reduces register usage a lot in some cases
1239 2006-03-04 Borut Razem <borut.razem AT siol.net>
1241 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3504 on rIfx (genCmp was broken)
3506 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3508 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3509 * src/z80/main.c (_keywords[]),
3510 * src/SDCCglobal.h (struct options),
3512 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3513 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3514 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3515 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3516 always available in leading double underscore form. The C99 support is
3517 mostly missing, but it's a start.
3518 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3519 reserved identifier "__data".
3521 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3567 2005-03-20 Borut Razem <borut.razem AT siol.net>
3569 * support/scripts/inc2h.pl: WIN32 port

3597 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3599 * device/lib/printf_large.c: removed inline assembly for portability and
3600 readability. Use printf_fast if speed or size are more important.
3601 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3602 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3604 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3606 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3607 prevent compiler warning
3609 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3611 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3612 moved to level 0 and declared as static. Also they are explicit
3613 placed in access bank. This was necessery because some times they
3614 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3615 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3616 optimizations. Currently only compare to unsigned char is implemented,
3617 * src/pic16/gen.c: added fReturnIdx array,
3618 * (struct resolvedIfx) is moved to gen.h and made public,
3619 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3620 * (aopForSym): added an optimization to directly store in stack of
3621 the operand of a SEND iCode,
3622 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3623 but as registers instead (AOP_REG) using the fReturnIdx array,
3624 * (pic16_freeAsmop): remove the freed register from the
3625 _G.sregsAlloc field,
3626 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3627 a compare of 'WREG',
3628 * (pic16_popGetTempRegCond): changed function prototype, now
3629 function takes also a bitVector argument v which holds the current
3630 set of registers that are allocated for stack access by aopForSym,
3631 registers allocated in aopForSym for accessing stack symbols are not
3632 any more part of the functions usedRegs field,
3633 * (genCall): some times aopOp is called for a stack variable to be
3634 send, aopForSym might perform the push, if this is true make sure
3635 that genCall doesn't push the variable twice by testing _G.resDirect,
3636 * (genFunction): changed testing for unspecified interrupt number
3637 from 256 to INTNO_UNSPEC,
3638 * modified selection scheme of frame pointer generation. Previously
3639 if function did use local registers a frame pointer was generated,
3640 now a frame pointer is generated only if function has arguments
3641 (that need PLUSW2 register access), or has stack arguments, or the
3642 compiler is not instructed to omit the frame pointer,
3643 * (genEndFunction): before restoring local registers that were saved
3644 in the function preamble, also restore the registers that *might*
3645 have been allocated for stack access,
3646 * (genRet): removed some old comments,
3647 * (genCmp, the active (RN's) version): added a call to the
3648 pic16_genCmp_special function to perform the compare with a more
3649 robust and optimized way,
3650 * (genInline): a feature has been added in inline code generation,
3651 which allows a wildcard variable substitution when writing inline
3652 assembly. Code is incomplete and experimental therefore undocumented,
3653 * (genCast): changed order of aopOp for result and right to allow
3654 aopForSym to directly load the result if possible,
3655 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3656 perform an optimized compare on some selected special occasions,
3657 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3658 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3659 generate an IVT any more,
3660 * src/pic16/main.c (pic16_optionsTable): added command line option
3662 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3663 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3665 * src/pic16/NOTES: Raphael Neider added in list of active developers
3666 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3667 jumptable_end to prevent bug #,
3668 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3669 inCond and outCond fields,
3670 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3671 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3672 turn off register spilling,
3673 * (packRegsForOneUse): synced with other ports' versions although it
3674 is not used currently,
3675 * (pic16_packRegisters): added an optimization while reading
3676 structure bitfields, some registers may be saved (malloc code is
3677 decreased by 80 bytes)
3679 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3681 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3682 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3683 this can be optimized more?
3685 2005-03-10 Raphael Neider <rneider AT web.de>
3687 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3688 genNearPointerGet): (hopefully) fixed access to bitfields via
3689 pointers (p->bitN = x; and x = p->bitN; failed)
3691 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3734 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3735 to keep the correct label reference count when adding/removing references
3736 to labels. A peephole file using this is appended to patch #1144962.

3868 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3869 (sizeof(sectNames) changed to sizeof(sectName))
3870 Both patches fix segfaults under MinGW.

3875 Safe_[mc]?alloc()'ed variables
3876 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3877 of (byte sized) temporaries (assign them to WREG for now)
3878 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3879 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3880 this might fix SIGSEGVs on MinGW...
3881 * src/SDCCopt.c (killDeadCode): restored original behaviour
3882 (volatile operands might get thrown away though)
3884 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3886 * src/pic16/gen.c: fixed bug #1106975,

4348 * src/pic16/genarith.c,
4351 * src/pic16/pcode.c: applied patches #1068154 and #1070213
4353 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4355 Large cummulative patch for pic16 port.
4356 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4357 to call when a stack overflow occurs,
4358 * (malloc.h): added CVS Id tag,
4359 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4361 * added libc directory. The current version of LibC contains string
4362 functions, ctype functions and macros and some functions of the
4363 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4364 be extensively tested in the future. Standard disclaimer here.
4365 Library is not automatically build yet. But one can build it by
4366 invoking 'make' inside the libc directory.
4367 * added ADC library under libio. Preliminary version yet.
4369 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4370 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4371 aopForRemat() now and not by pic16_aopOp(),
4372 * (pic16_popGetTempReg): removed warning messgae when allocating
4373 temporary registers, its a buggy feature and will be removed,
4374 * (pic16_popGet): set register instance field in AOP_CRY,
4375 * (pic16_outBitC): fixed for results in size greater than 1,
4376 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4377 * (pic16_storeForReturn): optimized return of 0,
4378 * (genCmp): experimental code for new genCmp which uses PIC18's
4379 special compare&skip instructions. Initial tests fail some times
4380 with variables grater than 1 byte in size, so new code is disabled,
4381 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4383 * (genCast): began a fix to optimize the casting of a bit to another
4384 bit, now assigning a bitfield to another bitfield will fail, sorry,
4385 * src/pic16/main.c: disabled the use of lr-support feature,
4386 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4387 * added some function prototypes, added function _debugf prototype,
4388 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4389 bits with offset (case PO_GPR_BIT),
4390 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4392 * (isBankInstruction): modified to return 0 for no banking instruction,
4393 and 1 for banking instruction,
4394 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4395 caused stop processing pCodes after a inline assembly block,
4396 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4397 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4398 registers when it shouldn't,
4399 * src/pic16/ralloc.c (allocReg): add preliminary support for
4400 supporting a limited set of temporary registers,
4402 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4404 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4405 genDataPointerSet): ensure assignments always copy in MSB to LSB
4407 (loadRegFromAop): recognize CLRH optimization,
4408 (genFunction): optimize RECEIVE iCodes in reentrant functions
4410 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4412 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4413 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4415 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4421 * device/lib/_gptrget.c (_gptrget),
4422 * device/lib/_gptrgetc.c (_gptrgetc),
4423 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4424 instead of sjmp to ret
4425 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4426 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

7410 loaded with the linker search paths (-L arguments) and the libraries
7411 to be linked with the current source (-l arguments). Changes
7412 currently will affect only the pic16 port.
7413 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7414 include path the port specific paths and port specific libraries,

7435 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7436 when generating output files to configure the pic16 library,
7437 but now I've commented it out, since gputils aren't installed in the
7438 SF compile farm, so library won't compile
7440 * device/lib/Makefile.in (version 1.56): initially I've added in
7441 target 'all' the prerequestive 'model-pic16' so it compiled the
7442 pic16 library, but now I've commented it out for the same reasons
7444 * added targets 'model-pic16' and 'objects-pic16' to compile the
7446 * added target 'port-specific-objects-pic16' to handle the
7447 generated libraries and copy them into the build/ directory
7448 * added target 'clean-intermediate-pic16' to clean intermediate
7449 files into pic16 directory
7450 * in target 'installdirs' added line to create directory pic16 in
7451 the installation path
7453 * device/include/Makefile.in (version 1.11): in target 'install'
7454 added lines to copy all header files to installation path,
7455 * in target 'installdirs' added line create directory for pic16
7456 headers in the installation path

7471 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7472 option so that it actually works. Made it specific to the z80, since
7473 the gbz80 doesn't have these kinds of I/O ports.
7475 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7477 * device/include/z180.h,

7483 * device/lib/_strcmp.c,
7484 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
7485 * src/z80/main.c (_process_pragma): add support for pragmas bank and
7486 portmode; added deprecation warning for bank= and protmode= forms.
7487 Also, guard against buffer overflow.
7488 * src/z80/gen.c (aopGet): generate better code for sfr banked read
7490 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7492 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

7495 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7497 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7499 Mainly changes to support compilation of the device libraries
7500 * src/pic16/device.c: stack is allocated via symbol and not
7501 via literal number. The symbol is placed in the corresponding
7502 position of the data ram
7503 * (pic16_dump_section): relocatable and absolute uninitialized
7504 data are now emitted in sorted order to reduce section naming,
7505 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7506 weren't marked as being in the access bank,
7508 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7510 Added portion of GNU PIC Library under the directory
7511 device/include/pic16 and device/lib/pic16. These files
7512 contain the declarations of SFRs for the PIC18Fxx2 devices.
7513 The directory is initialized via configure from toplevel.
7515 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7517 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7518 the spilllocations to be compared correctly
7520 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7522 * src/SDCCast.c (decorateType): fixed bug introduced today
7524 2004-01-12 Borut Razem <borut.razem AT siol.net>

7542 * doc/sdccman.lyx: Moved and added some sections, small changes
7543 all over. Telling LaTeX to be less strict with word spacing
7544 to better keep the right margin. Changed some notes about
7545 maintainance of the ports in section 3.2.1 - is it OK like this?
7547 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7584 UPPER for immediate operands,
7585 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7587 * src/pic16/peeph.def: all peepholes with movff are commented out,
7588 because there is a problem in the pcode peep optimizer,
7589 * src/pic16/ralloc.c: the register allocator can now reuse local

7591 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7593 Added file src/pic16/NOTES with information about program writing on
7594 the current port version.

7699 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7701 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7702 (default behaviour).
7704 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7706 A python script to validate compiler diagnostic messages. It can be
7707 used to verify that sdcc complains about bad c source code and
7708 gives a good location of the error.
7709 * support/valdiag/Makefile,
7710 * support/valdiag/valdiag.py,
7711 * support/valdiag/tests/*

7728 Bug reported from Jesus Calvino-Fraga
7730 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7732 * sdcc.spec: updated
7733 * device/include/Makefile.in: don't install CVS directories
7734 * device/lib/Makefile.in: added removal of CVS directories after install
7735 * doc/Makefile: fixed install, added local_icons
7736 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7737 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7738 * src/ds390/gen.c (genRightShift): fixed bug #870788
7739 * src/SDCCast.c (decorateType): fixed bug #870781
7741 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7743 PIC16 port related changes:
7744 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7745 added variable stackPos,
7747 * gen.c: genCall, assignResultValue: added support for
7748 pushing/retrieving function parameters to/from stack,
7749 genFunction,genEndFunction: setup stack frame for the
7751 genAddrOf: will be changed according to bug 863624
7753 * added files genutils.c and genutils.h which contain gen*
7754 debugged and optimised functions extracted from gen.c
7756 * glue.c: added variable 'externs' which holds extern symbols,
7757 pic16emitRegularMap: is modified to properly handle relocatable
7758 symbols under the new scheme,
7759 pic16createInterruptVect: is modified
7760 pic16printPublics: is modified to emit 'global' assembler directives,
7761 added pic16_printExterns to print extern symbols,
7762 pic16glue: initializes stack/frame pointer in the beginning of
7763 the assembly output. Temporary hack, will be corrected later,
7764 because gplink yet does not support stack and SDCC does not
7765 yet support a type of crt0.o object to create the final binary.
7767 * Removed many lines that contain 8051 legacy code.
7768 * The code is finally placed under a 'code' directive.
7769 * Added port specific options.
7771 * _process_pragma: simplified since now we do not need *special*
7772 include file to define SFR registers. But a separate header
7773 will be needed. This will be developed later.
7774 * _pic16_parseOptions: added, parses port specific options:
7775 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7776 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7777 --preplace-udata-with=
7779 * _pic16_setDefaultOptions: modified to initialize section names,
7780 but hack is temporarly out of order since it needs improvement.
7781 * _pic16_genAssemblerPreamble: configuration words are emitted by
7782 their address instead of their name. This part is incomplete and
7783 supports only the 18Fxx2 devices. Other devices will emit an error
7784 during assembly since they do not contain the same set of config
7786 * _pic16_genIVT: is modified,
7788 * pcode.c: added definitions for some hardware registers that are needed
7790 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7791 All PCI entries are updated. Now LFSR is supported.
7792 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7793 * added pic16_newpCodeOpLit2 to support instructions with
7794 two literal arguments
7795 * pic16_pCode2str: corrected code that emits assembler instructions
7796 with two literal operands and those that have an access bit modifier
7797 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7798 this fixes a bug which caused some labels to be lost, when an
7799 assembler directive was added, i.e. banksel,
7800 * pic16_FixRegisterBanking: improved logic that causes the insertion
7802 * InlineFunction: functions that are called once, are not any more
7803 inlined. This can be a port option in the future,
7805 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7807 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7808 hold the corresponding uninitialized symbols,
7809 * pic16_allocProcessorRegister: registers have explicit marked the
7811 * pic16_allocInternalRegister: registers are explicit marked as
7813 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7814 processing list, so bit registers were lost,
7817 * ralloc.h: added field 'accessBank' and original symbol operand
7818 in register definition,
7819 * removed the field isMapped from register definition,
7821 ** Several functions have been removed from various sources:
7822 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7823 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7824 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7825 pic16_assignRelocatableRegisters
7827 ** others have been introduced:
7828 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7829 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7831 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7833 * support/scripts/inc2h.pl: changed definition of BIT_AT
7834 to emit 'sbit at' instead of 'bit at'. This was a request.
7836 PIC16 port related preliminary changes:
7837 * gen.c: prefixed function popRegFromString with
7838 pic16_ and all references to it corrected
7839 * pcode.c: all pic16_pc_* hardware registers prefixed
7840 with underscore (_),
7841 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7842 * ralloc.c: newReg(): when register is REG_SFR then
7843 set address to rIdx,
7844 pic16_allocProcessorRegister(): marks register wasUsed=0
7845 pic16_writeUsedRegs(): added a call to assign processor
7846 registers via pic16_assignFixedRegisters
7848 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7850 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7851 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7852 variables in unused register banks. Also the SSEG is placed
7853 wherever there is enough space for it, and IDATA can be anywhere
7854 in internal RAM. For now compile using -Wl-Y[stack_size].
7855 The mem file is different for this option as well, since it
7856 makes no sense of talking about DSEG lenght.
7858 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7860 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7861 in certain cases, e.g. when ROM assignment, patch provided
7862 from Albert den Haan.
7864 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8417 not occur if the control variable is involved with a
8418 relational operator.

8911 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8913 Try to make the peephole optimizer smarter by maintaining
8914 an association between the assembly source code and the
8915 iCodes that originated them. Put this information to use
8916 with a new peephole rule condition "notVolatile" so that
8917 the rules can be aggressive yet still safe.

8930 if the left or right operand symbols have the accuse flag set.
8932 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8934 Changed the type of the result of the ! (NOT) operator to char;
8935 previously it returned the same type as the source. This allows
8936 us to eliminate all the genFloatNot functions (all of its target
8937 implementations were very buggy) since !float can use the same
8940 * src/SDCCicode.c (ast2iCode): ! returns char

8949 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8950 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8951 during interrupts. Ensure WSAVE is located at a shared bank address.
8952 2. Fixed page selection in some places
8953 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8954 the registers name strings.
8955 4. Fixed "signed / unsigned compare" compiler warnings.
8956 5. The PIC port manages its own allocation of the general purpose
8957 registers, but makes no attempt to reuse them. As a result when
8958 compiling it soon runs out of general purpose registers. Some
8959 additional code was added to the files pcode.c and device.c to walk
8960 through the function call tree and rename the registers so that they
8970 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8977 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8979 Made bitfield a distinct type from bit so that bitfields
8980 convert as per ANSI C and bits retain their traditional
8981 boolean style behaviour. Implemented bitfield support in
8989 * src/ds390/gen.c: bit v bitfield split
8990 * src/z80/gen.c: New support for bitfields
8991 * support/regression/tests/bitfields.c: reenabled z80,
8994 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8996 Rules 246.x, 247.x relate to bitfields, the others speed up
8997 access to xdata mapped I/O devices.
8999 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9001 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9003 Cleaned up genPackBits and genUnpackBits and added two helper
9004 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9005 for literal assignments in genPackBits (thanks to Frieder for
9011 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9013 Fixed bug #748310 (pointer to function type mishandled when the
9014 function name is omitted). Also fixed a SIGSEGV when a function
9015 attribute (reentrant, etc) is used on a non-function or on a
9016 function but misplaced before the parameter list.

9043 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9045 Made the constant following the "interrupt" keyword optional. If
9046 omitted, the function will not automatically be given an entry
9047 in the interrupt vector table (similar to #pragma NOIV, but
9048 less syntacticly kludgy). The interrupt number is also now
9049 range checked. Also fixed a bug in the high order bit example

9525 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9526 the regression tests I'm not brave enough to enable 245.b, 245.c
9527 * doc/sdccman.lyx: added latex preamble for hyperref package.
9528 Using pdflatex this will give you a hyperlinked pdf file with
9529 bookmarks. (prepend '%' before /usepackage if this breaks something)

9576 added --disable-pic16-port
9577 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9578 * src/SDCCmain.c: linkOptions is changed to set *,
9579 added if/endif conditional macros to remove options help
9580 messages from optionsTable when a port is not configured, added
9581 support for the PIc16 port in the ports table, when executing
9582 the compiler with no port specified on command line, a default
9583 port is selected with the new macro DEFAULT_PORT which is
9584 defined in port.h, in setDefaultOptions() linkOptions is removed
9585 from initialization assignment, since now it is a set,
9586 parseCmdLine uses setParseWithComma for linkOptions, in
9587 linkEdit() linkOptions are accessed with new function indexSet()
9588 which returns the i'th item of a set variable. See SDCCset.c, in
9589 linkEdit() when calling buildCmdLine(), added linkOptions as
9590 last argument. Now users can pass arguments to gplink via the
9591 -Wl option, main() uses pic16glue() to glue up pic16 programs
9592 * src/SDCCpeeph.c: various changes to support pic16

9603 * src/pic16/glue.c: commented out some error producing lines
9604 * src/pic16/main.c: __config directives are commented out to stop
9605 gpasm complaining and test the linkage with gplink, _linkCmd and
9606 _asmCmd changed to be more gplink and gpasm friendly
9607 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9608 produced an error when parsed, peep rule 12 is added to utilize
9609 movff, but it is commented out since the pCode does not support
9610 yet a command with 2 address arguments
9612 2003-05-18 <johan AT balder>
9614 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9639 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9641 2003-05-11 Borut Razem <borut.razem AT siol.net>
9643 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9644 the path of bin directory, so that PATH is the only env. variable, which has to be set
9645 in case of standard installation.
9646 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10675 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10677 * in \sdcc\as\mcs51\ changed these files in order to create an
10678 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10679 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10680 following files to include the previous two files: aslink.dsp,
10681 Makefile.aslink, Makefile.bcc, and Makefile.in.
10683 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10684 .adb instead of .cdb
10686 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10688 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10689 value from option --iram-size.
10691 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10693 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10696 2002-09-18 <wiml AT hhhh.org>
10698 * SDCClrange.h: exposed setFromRange() and setToRange()
10699 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10700 packRegsForAccUse() (bug 542397)
10701 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10702 multiple times and emitting the fetch operations more than once
10703 added aopGetUsesAcc() function to allow binary operators to
10704 fetch their operands in the correct order; made genMinus() emit
10705 compact code for X = LITERAL - Y
10707 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10708 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10709 sprintf() in line 1267.
10711 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10712 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10715 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10716 Changes to aslink (All the changes are marked with 'JCF'):
10718 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10721 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10722 area BSEG. Also moves, if possible, the DATA area down into the internal
10723 ram so more space is available.
10725 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10728 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10729 not bytes. Function summary() which creates a memory usage summary
10730 file with extension .mem. Reports of overlaping stack and small stack
10731 size. If the space for the stack is less than 16 bytes aslink trows a
10734 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10735 the 8051. Option 'y' for memory summary output file.
10737 Changes to sdcc (All the changes are marked with 'JCF'):
10739 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10741 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10742 overlaying area for it (uses RegBankUsed[4]).
10744 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10745 bank zero as used by default. By default aslink locates the stack
10746 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10747 the creation of the .mem file. Delegates the allocation of data area
10748 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10749 the begining of the stack area to aslink.
10751 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10752 glue() in SDCCglue.c creates an area for it.
10754 2002-09-03 Borut Razem <borut.razem AT siol.net>
10755 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10756 sdcc/src/pic/glue.c:
10757 introduced atexit() handler for teporay files removal in case of
10758 errors, assertions, ...
10760 2002-08-29 Borut Razem <borut.razem AT siol.net>
10761 * sdcc/support/cpp2/auto-host_vc_in.h:
10762 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10763 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10764 Maybe there is a similar problem with BORLANDC? It should be checked!
10766 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10767 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10768 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10769 was not executed, and the compiler (cl) launched a warning:
10770 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10772 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10773 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10785 - added Release configuration in VS projects
10786 - review of compiler an linker options
10787 - VC .exe files are generated in bin_vc directory, not to interfere
10788 with binaries generated from other projects (cygwin, mingw, bcc ...)
10790 * sdcc/src/yacc.dsp: added
10792 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10793 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10794 and insert the version number definitions from .version
10796 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10798 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10805 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10807 2002-08-11 Borut Razem <borut.razem AT siol.net>
10808 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10810 2002-08-10 Borut Razem <borut.razem AT siol.net>
10811 * src/SDCCmain.c (main):
10812 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10813 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10814 The consequence was that some temporary files were not removed.
10817 unification of code in functions tempfilename() and tempfile():
10818 function tempnam() is defined in Visual Studio 6.0 and .NET
10820 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10822 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10823 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10824 - removed compiler command line option /WX: Treats all warnings as errors
10825 - update a list of source files, included into the project
10827 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10828 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10829 changed project type to Generic Project so that can be correcly converted to VS.NET project
10831 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10833 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10837 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10838 added return 0 statements after assert() to make compiler happy
10840 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10841 added newline in the def file to keep MSC compiler satisfied
10843 * sdcc/src/z80/gen.c:
10844 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10845 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10846 - solved MSC error in function aopDump()
10848 * sdcc_vc.h: define PREFIX as "\\sdcc"
10850 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11025 * sdcc/src/SDCCloop.c:
11026 Previous fix was not good. basic blocks that have "break" or "return" are
11027 not really partof a loop , but live ranges used in these blocks should
