867 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
869 Enabled VPATH feature: changed nearly all Makefiles (149 files).
870 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
872 One basic decision: e.g. src/clean.mk includes further files. In order
873 to make this work there are two solutions:
874 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
875 run configure on them. This way they can use
876 'include $(srcdir)/port-clean.mk'
877 - always include clean.mk by the Makefile at the same level. To avoid
878 that `make clean` tries to include and build Makefile.dep the
879 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
880 implemented, because now even `make uninstall` doesn't create
881 Makefile.in. clean.mk could be eliminated by pasting it in
884 * debugger/mcs51/Makefile.in: build own objects from library sources
885 (SLIB, SDCC) in current directory
887 * configure, configure.in: renamed --disable-device-lib-build in
888 --disable-device-lib; added --enable-doc, the required tools are
889 searched by configure; added result message; the toolchain for the
890 belonging ports are now only built, if the port is enabled.
892 * support/regression/*: all output is written in directory gen, because
893 the fwk and ports directories don't livet in the build tree using vpath
895 * doc/sdccman.lyx: renamed --disable-device-lib-build to
896 --disable-device-lib, added --enable-doc, added section VPATH
898 * sim/ucsim/configure.in,
899 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
900 z80 are enabled by default
902 2006-04-24 Raphael Neider <rneider AT web.de>
904 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
905 to config word, "pic14_"-prefixed some extern functions
906 (pic14_emitConfigWord): emit __config directive(s) if assignment to
907 config word has been found
908 * src/pic/device.h: added prototypes
909 * src/pic/pcode.c: added "pic14_"-prefix where needed
910 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
912 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
914 (pic14emitRegularMap): ignore config words,
915 (pic14createInterruptVect): moved generating __config directives away
916 (picglue): have __config directives emitted
918 2006-04-24 Borut Razem <borut.razem AT siol.net>
920 * doc/Makefile: sync with nightly build makefile

925 registers that have not been assigned proper liveranges,
926 fixes #1469504 and #1474602,
927 (pCodeRegOptimizeRegUsage): fixed typo in comment
929 2006-04-24 Borut Razem <borut.razem AT siol.net>
931 * device/examples/main8051.c: deleted - it was removed from CVS
932 24.mar.2000 and after that modified 18.feb.2001, so it reappered
933 after the transition to Subversion
934 * src/SDCCalloc.h: deleted - it was removed from CVS
935 3.feb.2001 and after that modified 18.feb.2001, so it reappered
936 after the transition to Subversion

1175 and enabled nesting of critical functions though not for gbz80
1176 (genCritical, genEndCritical): added functions
1177 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1178 * src/z80/mappings.i: added "ei" to all mappings

1190 the left operand is shorter than the result (c* = lit-c* + int),
1192 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1195 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1197 * src/.version: increased version number to 2.5.5
1198 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1199 linking is done manually in pic16 port's _linkEdit,
1200 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1201 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1202 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1203 allocate asmop as AOP_ACC,
1204 (aopForRemat): added parameter 'bool result' in function declaration,
1205 (pic16_aopGet): return AOP_ACC when accessing WREG,
1206 (pic16_popGetTempReg): minor modification,

1217 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1218 call to allocReg, not by manually allocating a new one,
1219 (pic16_assignRegisters): now before going through the register
1220 allocating functions mark all registers as free. This eliminates some
1221 side effects resulting from peephole parser done earlier in the backbone
1223 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1281 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1282 which dumps before the function entry point a data byte which represents
1283 the number of the local variables used by the specified function, added
1284 'xinst' for initial support for Extended Instruction Support,
1285 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1286 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1287 port->fun_prefix anymore (may change later),
1288 (genFunction, genEndFunction): do not store/restore local registers for
1289 _main (this should take care the --main-return command line option in
1291 (genOr): removed some legacy pic-port instructions,
1292 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1293 performing operations with SFR's causes data to be written more than
1294 once to each SFR. Perhaps SFRs should be handled in special cases...
1295 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1297 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1298 into account for stack starting position,

1300 --extended or -y for Extended Instruction Support,
1301 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1302 (deassignLRs): *** perhaps the most important change, old 'for' code
1303 (commented out for reference), didn't account for some registers which
1304 were left marked 'not free' after a pointer operation. The change
1305 reduces register usage a lot in some cases
1307 2006-03-04 Borut Razem <borut.razem AT siol.net>

3582 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3583 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3584 always available in leading double underscore form. The C99 support is
3585 mostly missing, but it's a start.
3586 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3667 * device/lib/printf_large.c: removed inline assembly for portability and
3668 readability. Use printf_fast if speed or size are more important.
3669 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3670 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3672 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3674 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3675 prevent compiler warning
3677 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3679 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3680 moved to level 0 and declared as static. Also they are explicit
3681 placed in access bank. This was necessery because some times they
3682 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3683 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3684 optimizations. Currently only compare to unsigned char is implemented,
3685 * src/pic16/gen.c: added fReturnIdx array,
3686 * (struct resolvedIfx) is moved to gen.h and made public,
3687 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3688 * (aopForSym): added an optimization to directly store in stack of
3689 the operand of a SEND iCode,
3690 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3691 but as registers instead (AOP_REG) using the fReturnIdx array,
3692 * (pic16_freeAsmop): remove the freed register from the
3693 _G.sregsAlloc field,
3694 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3695 a compare of 'WREG',
3696 * (pic16_popGetTempRegCond): changed function prototype, now
3697 function takes also a bitVector argument v which holds the current
3698 set of registers that are allocated for stack access by aopForSym,
3699 registers allocated in aopForSym for accessing stack symbols are not
3700 any more part of the functions usedRegs field,
3701 * (genCall): some times aopOp is called for a stack variable to be
3702 send, aopForSym might perform the push, if this is true make sure
3703 that genCall doesn't push the variable twice by testing _G.resDirect,
3704 * (genFunction): changed testing for unspecified interrupt number
3705 from 256 to INTNO_UNSPEC,
3706 * modified selection scheme of frame pointer generation. Previously
3707 if function did use local registers a frame pointer was generated,
3708 now a frame pointer is generated only if function has arguments
3709 (that need PLUSW2 register access), or has stack arguments, or the
3710 compiler is not instructed to omit the frame pointer,
3711 * (genEndFunction): before restoring local registers that were saved
3712 in the function preamble, also restore the registers that *might*
3713 have been allocated for stack access,
3714 * (genRet): removed some old comments,
3715 * (genCmp, the active (RN's) version): added a call to the
3716 pic16_genCmp_special function to perform the compare with a more
3717 robust and optimized way,
3718 * (genInline): a feature has been added in inline code generation,
3719 which allows a wildcard variable substitution when writing inline
3720 assembly. Code is incomplete and experimental therefore undocumented,
3721 * (genCast): changed order of aopOp for result and right to allow
3722 aopForSym to directly load the result if possible,
3723 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3724 perform an optimized compare on some selected special occasions,
3725 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3726 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3727 generate an IVT any more,
3728 * src/pic16/main.c (pic16_optionsTable): added command line option
3730 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3731 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3733 * src/pic16/NOTES: Raphael Neider added in list of active developers
3734 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3735 jumptable_end to prevent bug #,
3736 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3737 inCond and outCond fields,
3738 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3739 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3740 turn off register spilling,
3741 * (packRegsForOneUse): synced with other ports' versions although it
3742 is not used currently,
3743 * (pic16_packRegisters): added an optimization while reading
3744 structure bitfields, some registers may be saved (malloc code is
3745 decreased by 80 bytes)
3747 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3749 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3750 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3751 this can be optimized more?
3753 2005-03-10 Raphael Neider <rneider AT web.de>
3755 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3756 genNearPointerGet): (hopefully) fixed access to bitfields via
3757 pointers (p->bitN = x; and x = p->bitN; failed)

4391 Adding support for replacing ljmps with sjmps in jumptables
4392 generated for switch statements. For now you need to set the
4393 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4394 Now 4 algorithms for mcs51 jumptable generation are used:
4395 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4396 addresses loaded pc-relative for up to 112 cases and stack-pushing
4397 target addresses loaded with offset from dptr for up to 256 cases.
4399 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4400 * src/mcs51/main.c: adapted constants for switch table generation

4424 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4425 to call when a stack overflow occurs,
4426 * (malloc.h): added CVS Id tag,
4427 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4429 * added libc directory. The current version of LibC contains string
4430 functions, ctype functions and macros and some functions of the
4431 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4432 be extensively tested in the future. Standard disclaimer here.
4433 Library is not automatically build yet. But one can build it by
4434 invoking 'make' inside the libc directory.
4435 * added ADC library under libio. Preliminary version yet.
4437 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4444 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4445 * (pic16_storeForReturn): optimized return of 0,
4446 * (genCmp): experimental code for new genCmp which uses PIC18's
4447 special compare&skip instructions. Initial tests fail some times
4448 with variables grater than 1 byte in size, so new code is disabled,
4449 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4451 * (genCast): began a fix to optimize the casting of a bit to another
4452 bit, now assigning a bitfield to another bitfield will fail, sorry,
4453 * src/pic16/main.c: disabled the use of lr-support feature,
4454 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4457 bits with offset (case PO_GPR_BIT),
4458 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4460 * (isBankInstruction): modified to return 0 for no banking instruction,
4461 and 1 for banking instruction,
4462 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4463 caused stop processing pCodes after a inline assembly block,
4464 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4465 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4466 registers when it shouldn't,
4467 * src/pic16/ralloc.c (allocReg): add preliminary support for
4468 supporting a limited set of temporary registers,
4470 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4472 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4473 genDataPointerSet): ensure assignments always copy in MSB to LSB
4475 (loadRegFromAop): recognize CLRH optimization,
4476 (genFunction): optimize RECEIVE iCodes in reentrant functions
4478 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4480 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7475 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7477 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7478 loaded with the linker search paths (-L arguments) and the libraries
7479 to be linked with the current source (-l arguments). Changes
7480 currently will affect only the pic16 port.
7481 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7482 include path the port specific paths and port specific libraries,
7483 * gplink command now contains the $3 argument,
7484 * src/pic16/device.h,
7485 * src/pic16/device.c,: structure PIC_device is made public and
7486 renamed to PIC16_device, the same for variable Pics which is renamed

7499 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7501 Documenting changes from previous commits.
7502 * configure.in (version 1.56),
7503 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7504 when generating output files to configure the pic16 library,
7505 but now I've commented it out, since gputils aren't installed in the
7506 SF compile farm, so library won't compile
7508 * device/lib/Makefile.in (version 1.56): initially I've added in
7509 target 'all' the prerequestive 'model-pic16' so it compiled the
7510 pic16 library, but now I've commented it out for the same reasons
7512 * added targets 'model-pic16' and 'objects-pic16' to compile the
7514 * added target 'port-specific-objects-pic16' to handle the
7515 generated libraries and copy them into the build/ directory
7516 * added target 'clean-intermediate-pic16' to clean intermediate
7517 files into pic16 directory
7518 * in target 'installdirs' added line to create directory pic16 in
7519 the installation path
7521 * device/include/Makefile.in (version 1.11): in target 'install'
7522 added lines to copy all header files to installation path,
7523 * in target 'installdirs' added line create directory for pic16
7524 headers in the installation path

7539 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7540 option so that it actually works. Made it specific to the z80, since
7541 the gbz80 doesn't have these kinds of I/O ports.
7543 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7545 * device/include/z180.h,

7558 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7560 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7561 changed interrupt vector table generation to only emit declared vectors.
7562 * device/include/Makefile.in: added missing backslash
7563 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7565 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7567 Mainly changes to support compilation of the device libraries
7568 * src/pic16/device.c: stack is allocated via symbol and not
7569 via literal number. The symbol is placed in the corresponding
7570 position of the data ram
7571 * (pic16_dump_section): relocatable and absolute uninitialized
7572 data are now emitted in sorted order to reduce section naming,
7573 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7574 weren't marked as being in the access bank,
7576 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7578 Added portion of GNU PIC Library under the directory
7579 device/include/pic16 and device/lib/pic16. These files
7580 contain the declarations of SFRs for the PIC18Fxx2 devices.
7581 The directory is initialized via configure from toplevel.
7583 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7585 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7586 the spilllocations to be compared correctly
7588 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7590 * src/SDCCast.c (decorateType): fixed bug introduced today
7592 2004-01-12 Borut Razem <borut.razem AT siol.net>
7594 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7597 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7599 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7600 in simpler and even better code
7602 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7604 * src/SDCCicode.c (operandOperation): fixed bug #874819

7610 * doc/sdccman.lyx: Moved and added some sections, small changes
7611 all over. Telling LaTeX to be less strict with word spacing
7612 to better keep the right margin. Changed some notes about
7613 maintainance of the ports in section 3.2.1 - is it OK like this?
7615 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7652 UPPER for immediate operands,
7653 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7655 * src/pic16/peeph.def: all peepholes with movff are commented out,
7656 because there is a problem in the pcode peep optimizer,
7657 * src/pic16/ralloc.c: the register allocator can now reuse local
7658 function symbols for another function. This saves register usage.
7659 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7661 Added file src/pic16/NOTES with information about program writing on
7662 the current port version.

7694 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7697 * src/z80/main.c: added missed needLinkerScript flags (more than
7698 one port structure defined in these file)
7699 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7715 needLinkerScript flag
7717 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7718 * src/pic/glue.c: added variable udata_section_name to
7719 override default uninitialized data segment definition for

7722 directive when no overlay data exist
7723 * (picglue): modified to emit uninitialized data segment
7724 according to udata_section_name

7729 arguments via -W option
7730 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7731 object file from '.rel' to '.o' in port->linker structure,
7732 changed size of fptr from 2 to 3 in port structure
7734 2004-01-07 Borut Razem <borut.razem AT siol.net>
7736 * support/scripts/sdcc.nsi: update PATH
7737 * support/scripts/sdcc.ico: craeted

7750 include information about variables allocated to the overlay
7753 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7755 * as/mcs51/lkmain.c: Help about -Y option

7767 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7769 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7770 (default behaviour).
7772 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7774 A python script to validate compiler diagnostic messages. It can be
7775 used to verify that sdcc complains about bad c source code and
7776 gives a good location of the error.
7777 * support/valdiag/Makefile,
7778 * support/valdiag/valdiag.py,
7779 * support/valdiag/tests/*
7781 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7794 * src/common.h: added ifndef/define/endif macros
7795 around the header file.
7796 Bug reported from Jesus Calvino-Fraga
7798 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7800 * sdcc.spec: updated
7801 * device/include/Makefile.in: don't install CVS directories
7802 * device/lib/Makefile.in: added removal of CVS directories after install
7803 * doc/Makefile: fixed install, added local_icons
7804 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7805 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7806 * src/ds390/gen.c (genRightShift): fixed bug #870788
7807 * src/SDCCast.c (decorateType): fixed bug #870781
7809 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7811 PIC16 port related changes:
7812 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7813 added variable stackPos,
7815 * gen.c: genCall, assignResultValue: added support for
7816 pushing/retrieving function parameters to/from stack,
7817 genFunction,genEndFunction: setup stack frame for the
7819 genAddrOf: will be changed according to bug 863624
7821 * added files genutils.c and genutils.h which contain gen*
7822 debugged and optimised functions extracted from gen.c
7824 * glue.c: added variable 'externs' which holds extern symbols,
7825 pic16emitRegularMap: is modified to properly handle relocatable
7826 symbols under the new scheme,
7827 pic16createInterruptVect: is modified
7828 pic16printPublics: is modified to emit 'global' assembler directives,
7829 added pic16_printExterns to print extern symbols,
7830 pic16glue: initializes stack/frame pointer in the beginning of
7831 the assembly output. Temporary hack, will be corrected later,
7832 because gplink yet does not support stack and SDCC does not
7833 yet support a type of crt0.o object to create the final binary.
7835 * Removed many lines that contain 8051 legacy code.
7836 * The code is finally placed under a 'code' directive.
7837 * Added port specific options.
7839 * _process_pragma: simplified since now we do not need *special*
7840 include file to define SFR registers. But a separate header
7841 will be needed. This will be developed later.
7842 * _pic16_parseOptions: added, parses port specific options:
7843 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7844 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7845 --preplace-udata-with=
7847 * _pic16_setDefaultOptions: modified to initialize section names,
7848 but hack is temporarly out of order since it needs improvement.
7849 * _pic16_genAssemblerPreamble: configuration words are emitted by
7850 their address instead of their name. This part is incomplete and
7851 supports only the 18Fxx2 devices. Other devices will emit an error
7852 during assembly since they do not contain the same set of config
7854 * _pic16_genIVT: is modified,
7856 * pcode.c: added definitions for some hardware registers that are needed
7858 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7859 All PCI entries are updated. Now LFSR is supported.
7860 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7861 * added pic16_newpCodeOpLit2 to support instructions with
7862 two literal arguments
7863 * pic16_pCode2str: corrected code that emits assembler instructions
7864 with two literal operands and those that have an access bit modifier
7865 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7866 this fixes a bug which caused some labels to be lost, when an
7867 assembler directive was added, i.e. banksel,
7868 * pic16_FixRegisterBanking: improved logic that causes the insertion
7870 * InlineFunction: functions that are called once, are not any more
7871 inlined. This can be a port option in the future,
7873 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7875 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7876 hold the corresponding uninitialized symbols,
7877 * pic16_allocProcessorRegister: registers have explicit marked the
7879 * pic16_allocInternalRegister: registers are explicit marked as
7881 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7882 processing list, so bit registers were lost,
7885 * ralloc.h: added field 'accessBank' and original symbol operand
7886 in register definition,
7887 * removed the field isMapped from register definition,
7889 ** Several functions have been removed from various sources:
7890 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7891 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7892 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7893 pic16_assignRelocatableRegisters
7895 ** others have been introduced:
7896 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7897 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7899 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7901 * support/scripts/inc2h.pl: changed definition of BIT_AT
7902 to emit 'sbit at' instead of 'bit at'. This was a request.
7904 PIC16 port related preliminary changes:
7905 * gen.c: prefixed function popRegFromString with
7906 pic16_ and all references to it corrected
7907 * pcode.c: all pic16_pc_* hardware registers prefixed
7908 with underscore (_),
7909 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7910 * ralloc.c: newReg(): when register is REG_SFR then
7911 set address to rIdx,
7912 pic16_allocProcessorRegister(): marks register wasUsed=0
7913 pic16_writeUsedRegs(): added a call to assign processor
7914 registers via pic16_assignFixedRegisters
7916 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7918 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7919 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7920 variables in unused register banks. Also the SSEG is placed
7921 wherever there is enough space for it, and IDATA can be anywhere
7922 in internal RAM. For now compile using -Wl-Y[stack_size].
7923 The mem file is different for this option as well, since it
7924 makes no sense of talking about DSEG lenght.

8919 and JUMPTABLE iCodes properly now (worked by accident before)
8920 * src/mcs51/gen.c (leftRightUseAcc),
8921 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8922 iCode properly now. Use getSize instead of nRegs since a & b
8923 aren't part of the nRegs tally.
8925 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8927 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8928 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8929 before instructions that use the _STATUS register
8931 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8933 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8934 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8935 fetching of the pointer
8936 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8937 copied from genNearPointerSet()
8938 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8939 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8940 If they pop r0/r1 they must be called in the opposite order than aopOp().
8941 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8942 (resp. --stack-auto), prepared for --xstack
8944 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8948 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8950 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8951 these ports have their own __sdcc_external_start()
8953 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8955 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8956 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8957 type for bits was changed. It resulted in bit variables becoming
8958 global, which is not permitted in PIC 14 assembly output.
8960 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8962 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8964 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8966 Z80 and MCS51 linkers complaint if a public symbol is defined
8967 in more than one library module:
8971 * as/mcs51/Makefile.in
8973 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8975 A few small changes that speed up the peephole optimizer.
8979 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8981 Try to make the peephole optimizer smarter by maintaining
8982 an association between the assembly source code and the
8983 iCodes that originated them. Put this information to use
8984 with a new peephole rule condition "notVolatile" so that
8985 the rules can be aggressive yet still safe.
8990 * src/mcs51/peeph.def
8992 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8996 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8997 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8998 if the left or right operand symbols have the accuse flag set.
9000 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9002 Changed the type of the result of the ! (NOT) operator to char;
9003 previously it returned the same type as the source. This allows
9004 us to eliminate all the genFloatNot functions (all of its target
9005 implementations were very buggy) since !float can use the same
9008 * src/SDCCicode.c (ast2iCode): ! returns char
9009 * src/mcs51/gen.c (genNot, genNotFloat),
9010 * src/ds390/gen.c (genNot, genNotFloat),
9011 * src/z80/gen.c (genNot, genNotFloat),
9012 * src/pic/gen.c (genNot, genNotFloat),
9013 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9015 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9017 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9018 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9019 during interrupts. Ensure WSAVE is located at a shared bank address.
9020 2. Fixed page selection in some places
9021 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9022 the registers name strings.
9023 4. Fixed "signed / unsigned compare" compiler warnings.
9024 5. The PIC port manages its own allocation of the general purpose
9025 registers, but makes no attempt to reuse them. As a result when
9026 compiling it soon runs out of general purpose registers. Some
9027 additional code was added to the files pcode.c and device.c to walk
9028 through the function call tree and rename the registers so that they
9038 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9039 genPlus() & genMinus() when the result is the same as left or right

9045 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9047 Made bitfield a distinct type from bit so that bitfields
9048 convert as per ANSI C and bits retain their traditional
9049 boolean style behaviour. Implemented bitfield support in
9057 * src/ds390/gen.c: bit v bitfield split
9058 * src/z80/gen.c: New support for bitfields
9059 * support/regression/tests/bitfields.c: reenabled z80,
9062 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9064 Rules 246.x, 247.x relate to bitfields, the others speed up
9065 access to xdata mapped I/O devices.
9067 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9069 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9071 Cleaned up genPackBits and genUnpackBits and added two helper
9072 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9073 for literal assignments in genPackBits (thanks to Frieder for
9079 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9081 Fixed bug #748310 (pointer to function type mishandled when the
9082 function name is omitted). Also fixed a SIGSEGV when a function
9083 attribute (reentrant, etc) is used on a non-function or on a
9084 function but misplaced before the parameter list.
9086 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9088 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9089 * support/Util/SDCCerr.h,
9090 * support/Util/SDCCerr.c: Added func attr misuse error msg

9111 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9113 Made the constant following the "interrupt" keyword optional. If
9114 omitted, the function will not automatically be given an entry
9115 in the interrupt vector table (similar to #pragma NOIV, but
9116 less syntacticly kludgy). The interrupt number is also now
9117 range checked. Also fixed a bug in the high order bit example
9124 * support/Util/SDCCerr.c
9125 * support/Util/SDCCerr.h
9128 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9131 * src/SDCCicode.c (operandOperation): rewritten some ops
9132 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9133 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9135 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9136 be re-activated by defining REDUCE_LITERALS)
9137 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9138 unsigned, but are signed by default
9139 * src/SDCCval.c (constVal): rearranged
9140 * src/SDCCval.c (valMod): preliminary fix
9141 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9184 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9185 * src/SDCCval.c (valDiv, valMod): fixed signdness
9186 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9187 signedness of modulo, left and right shift

9593 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9594 the regression tests I'm not brave enough to enable 245.b, 245.c
9595 * doc/sdccman.lyx: added latex preamble for hyperref package.
9596 Using pdflatex this will give you a hyperlinked pdf file with
9597 bookmarks. (prepend '%' before /usepackage if this breaks something)

9613 Applied patch from bug 737905 (renamed yylineo to mylineno):
9620 * src/pic16/pcode.c: Cleaned warnings
9621 * src/pic16/pcodeflow.c: Cleaned warnings
9622 * src/pic16/pcoderegs.c: Cleaned warnings

9635 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9637 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9638 it can be defined with CFLAGS when running configure
9639 * src/SDCCmain.c: fixed compiling + linking with object files
9641 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9644 added --disable-pic16-port
9645 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9646 * src/SDCCmain.c: linkOptions is changed to set *,
9647 added if/endif conditional macros to remove options help
9648 messages from optionsTable when a port is not configured, added
9649 support for the PIc16 port in the ports table, when executing
9650 the compiler with no port specified on command line, a default
9651 port is selected with the new macro DEFAULT_PORT which is
9652 defined in port.h, in setDefaultOptions() linkOptions is removed
9653 from initialization assignment, since now it is a set,
9654 parseCmdLine uses setParseWithComma for linkOptions, in
9655 linkEdit() linkOptions are accessed with new function indexSet()
9656 which returns the i'th item of a set variable. See SDCCset.c, in
9657 linkEdit() when calling buildCmdLine(), added linkOptions as
9658 last argument. Now users can pass arguments to gplink via the
9659 -Wl option, main() uses pic16glue() to glue up pic16 programs

9671 * src/pic16/glue.c: commented out some error producing lines
9672 * src/pic16/main.c: __config directives are commented out to stop
9673 gpasm complaining and test the linkage with gplink, _linkCmd and
9674 _asmCmd changed to be more gplink and gpasm friendly
9675 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9676 produced an error when parsed, peep rule 12 is added to utilize
9677 movff, but it is commented out since the pCode does not support
9678 yet a command with 2 address arguments
9680 2003-05-18 <johan AT balder>
9682 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9683 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9709 2003-05-11 Borut Razem <borut.razem AT siol.net>
9711 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9712 the path of bin directory, so that PATH is the only env. variable, which has to be set
9713 in case of standard installation.
9714 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10810 overlaying area for it (uses RegBankUsed[4]).
10812 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10813 bank zero as used by default. By default aslink locates the stack
10814 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10815 the creation of the .mem file. Delegates the allocation of data area
10816 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10817 the begining of the stack area to aslink.
10819 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10820 glue() in SDCCglue.c creates an area for it.
10822 2002-09-03 Borut Razem <borut.razem AT siol.net>
10823 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10824 sdcc/src/pic/glue.c:
10825 introduced atexit() handler for teporay files removal in case of
10826 errors, assertions, ...
10828 2002-08-29 Borut Razem <borut.razem AT siol.net>
10829 * sdcc/support/cpp2/auto-host_vc_in.h:
10830 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10831 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10832 Maybe there is a similar problem with BORLANDC? It should be checked!
10834 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10835 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10836 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10837 was not executed, and the compiler (cl) launched a warning:
10838 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10840 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10841 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10843 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10844 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10846 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10847 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10848 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10849 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10850 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10851 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10852 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10853 - added Release configuration in VS projects
10854 - review of compiler an linker options
10855 - VC .exe files are generated in bin_vc directory, not to interfere
10856 with binaries generated from other projects (cygwin, mingw, bcc ...)
10858 * sdcc/src/yacc.dsp: added
10860 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10861 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10862 and insert the version number definitions from .version
10864 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10866 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10867 added - genarate auto-host.h using auto-host_vc_in.h as template
10870 removed from CVS, generated automatically
10872 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10873 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10875 2002-08-11 Borut Razem <borut.razem AT siol.net>
10876 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10878 2002-08-10 Borut Razem <borut.razem AT siol.net>
10879 * src/SDCCmain.c (main):
10880 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10881 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10882 The consequence was that some temporary files were not removed.
10885 unification of code in functions tempfilename() and tempfile():
10886 function tempnam() is defined in Visual Studio 6.0 and .NET
10888 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10890 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10891 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10892 - removed compiler command line option /WX: Treats all warnings as errors
10893 - update a list of source files, included into the project
10895 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10896 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10897 changed project type to Generic Project so that can be correcly converted to VS.NET project
10899 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10901 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10903 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10905 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10906 added return 0 statements after assert() to make compiler happy
10908 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10909 added newline in the def file to keep MSC compiler satisfied
10911 * sdcc/src/z80/gen.c:
10912 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10913 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10914 - solved MSC error in function aopDump()
10916 * sdcc_vc.h: define PREFIX as "\\sdcc"
10918 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10919 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10967 Added -p option. Allows port dependent processor to be specified.
10970 Initialized the new field char *Processor field to NULL in all ports
10973 Compiler generated registers for interrupt context saving
10974 were not getting allocated.
10976 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10979 Fixed left shift. Will promote the left side of a left shift
10980 if a) left shifting more than size of operand or b) when assigned
10981 to something size > size of left side

11091 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11093 * sdcc/src/SDCCloop.c:
11094 Previous fix was not good. basic blocks that have "break" or "return" are
11095 not really partof a loop , but live ranges used in these blocks should
11096 be live thru the entire loop, so set partOfLoop but don't add them to
11099 2002-02-21 <johan AT FRIJA>
11101 * src/SDCCcse.c: fixed bug #514308
11103 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
