866 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
868 Enabled VPATH feature: changed nearly all Makefiles (149 files).
869 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
871 One basic decision: e.g. src/clean.mk includes further files. In order
872 to make this work there are two solutions:
873 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
874 run configure on them. This way they can use
875 'include $(srcdir)/port-clean.mk'
876 - always include clean.mk by the Makefile at the same level. To avoid
877 that `make clean` tries to include and build Makefile.dep the
878 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
879 implemented, because now even `make uninstall` doesn't create
880 Makefile.in. clean.mk could be eliminated by pasting it in
883 * debugger/mcs51/Makefile.in: build own objects from library sources
884 (SLIB, SDCC) in current directory
886 * configure, configure.in: renamed --disable-device-lib-build in
887 --disable-device-lib; added --enable-doc, the required tools are
888 searched by configure; added result message; the toolchain for the
889 belonging ports are now only built, if the port is enabled.
891 * support/regression/*: all output is written in directory gen, because
892 the fwk and ports directories don't livet in the build tree using vpath
894 * doc/sdccman.lyx: renamed --disable-device-lib-build to
895 --disable-device-lib, added --enable-doc, added section VPATH
897 * sim/ucsim/configure.in,
898 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
899 z80 are enabled by default
901 2006-04-24 Raphael Neider <rneider AT web.de>
903 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
904 to config word, "pic14_"-prefixed some extern functions
905 (pic14_emitConfigWord): emit __config directive(s) if assignment to
906 config word has been found
907 * src/pic/device.h: added prototypes
908 * src/pic/pcode.c: added "pic14_"-prefix where needed
909 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
911 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
913 (pic14emitRegularMap): ignore config words,
914 (pic14createInterruptVect): moved generating __config directives away
915 (picglue): have __config directives emitted
917 2006-04-24 Borut Razem <borut.razem AT siol.net>
919 * doc/Makefile: sync with nightly build makefile

924 registers that have not been assigned proper liveranges,
925 fixes #1469504 and #1474602,
926 (pCodeRegOptimizeRegUsage): fixed typo in comment
928 2006-04-24 Borut Razem <borut.razem AT siol.net>
930 * device/examples/main8051.c: deleted - it was removed from CVS
931 24.mar.2000 and after that modified 18.feb.2001, so it reappered
932 after the transition to Subversion
933 * src/SDCCalloc.h: deleted - it was removed from CVS
934 3.feb.2001 and after that modified 18.feb.2001, so it reappered
935 after the transition to Subversion

1174 and enabled nesting of critical functions though not for gbz80
1175 (genCritical, genEndCritical): added functions
1176 (genZ80Code): added cases for CRITICAL and ENDCRITICAL

1189 the left operand is shorter than the result (c* = lit-c* + int),
1191 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1194 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1196 * src/.version: increased version number to 2.5.5
1197 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1198 linking is done manually in pic16 port's _linkEdit,
1199 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1200 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1201 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1202 allocate asmop as AOP_ACC,
1203 (aopForRemat): added parameter 'bool result' in function declaration,
1204 (pic16_aopGet): return AOP_ACC when accessing WREG,
1205 (pic16_popGetTempReg): minor modification,

1216 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1217 call to allocReg, not by manually allocating a new one,
1218 (pic16_assignRegisters): now before going through the register
1219 allocating functions mark all registers as free. This eliminates some
1220 side effects resulting from peephole parser done earlier in the backbone
1222 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1280 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1281 which dumps before the function entry point a data byte which represents
1282 the number of the local variables used by the specified function, added
1283 'xinst' for initial support for Extended Instruction Support,
1284 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1285 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1286 port->fun_prefix anymore (may change later),
1287 (genFunction, genEndFunction): do not store/restore local registers for
1288 _main (this should take care the --main-return command line option in
1290 (genOr): removed some legacy pic-port instructions,
1291 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1292 performing operations with SFR's causes data to be written more than
1293 once to each SFR. Perhaps SFRs should be handled in special cases...
1294 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1296 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1297 into account for stack starting position,

1299 --extended or -y for Extended Instruction Support,
1300 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1301 (deassignLRs): *** perhaps the most important change, old 'for' code
1302 (commented out for reference), didn't account for some registers which
1303 were left marked 'not free' after a pointer operation. The change
1304 reduces register usage a lot in some cases
1306 2006-03-04 Borut Razem <borut.razem AT siol.net>

3581 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3582 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3583 always available in leading double underscore form. The C99 support is
3584 mostly missing, but it's a start.
3585 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3664 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3666 * device/lib/printf_large.c: removed inline assembly for portability and
3667 readability. Use printf_fast if speed or size are more important.
3668 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3669 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3671 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3673 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3674 prevent compiler warning
3676 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3678 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3679 moved to level 0 and declared as static. Also they are explicit
3680 placed in access bank. This was necessery because some times they
3681 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3682 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3683 optimizations. Currently only compare to unsigned char is implemented,
3684 * src/pic16/gen.c: added fReturnIdx array,
3685 * (struct resolvedIfx) is moved to gen.h and made public,
3686 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3687 * (aopForSym): added an optimization to directly store in stack of
3688 the operand of a SEND iCode,
3689 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3690 but as registers instead (AOP_REG) using the fReturnIdx array,
3691 * (pic16_freeAsmop): remove the freed register from the
3692 _G.sregsAlloc field,
3693 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3694 a compare of 'WREG',
3695 * (pic16_popGetTempRegCond): changed function prototype, now
3696 function takes also a bitVector argument v which holds the current
3697 set of registers that are allocated for stack access by aopForSym,
3698 registers allocated in aopForSym for accessing stack symbols are not
3699 any more part of the functions usedRegs field,
3700 * (genCall): some times aopOp is called for a stack variable to be
3701 send, aopForSym might perform the push, if this is true make sure
3702 that genCall doesn't push the variable twice by testing _G.resDirect,
3703 * (genFunction): changed testing for unspecified interrupt number
3704 from 256 to INTNO_UNSPEC,
3705 * modified selection scheme of frame pointer generation. Previously
3706 if function did use local registers a frame pointer was generated,
3707 now a frame pointer is generated only if function has arguments
3708 (that need PLUSW2 register access), or has stack arguments, or the
3709 compiler is not instructed to omit the frame pointer,
3710 * (genEndFunction): before restoring local registers that were saved
3711 in the function preamble, also restore the registers that *might*
3712 have been allocated for stack access,
3713 * (genRet): removed some old comments,
3714 * (genCmp, the active (RN's) version): added a call to the
3715 pic16_genCmp_special function to perform the compare with a more
3716 robust and optimized way,
3717 * (genInline): a feature has been added in inline code generation,
3718 which allows a wildcard variable substitution when writing inline
3719 assembly. Code is incomplete and experimental therefore undocumented,
3720 * (genCast): changed order of aopOp for result and right to allow
3721 aopForSym to directly load the result if possible,
3722 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3723 perform an optimized compare on some selected special occasions,
3724 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3725 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3726 generate an IVT any more,
3727 * src/pic16/main.c (pic16_optionsTable): added command line option
3729 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3730 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3732 * src/pic16/NOTES: Raphael Neider added in list of active developers
3733 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3734 jumptable_end to prevent bug #,
3735 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3736 inCond and outCond fields,
3737 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3738 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3739 turn off register spilling,
3740 * (packRegsForOneUse): synced with other ports' versions although it
3741 is not used currently,
3742 * (pic16_packRegisters): added an optimization while reading
3743 structure bitfields, some registers may be saved (malloc code is
3744 decreased by 80 bytes)
3746 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3748 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3749 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3750 this can be optimized more?
3752 2005-03-10 Raphael Neider <rneider AT web.de>
3754 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3755 genNearPointerGet): (hopefully) fixed access to bitfields via
3756 pointers (p->bitN = x; and x = p->bitN; failed)

4390 Adding support for replacing ljmps with sjmps in jumptables
4391 generated for switch statements. For now you need to set the
4392 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4393 Now 4 algorithms for mcs51 jumptable generation are used:
4394 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4395 addresses loaded pc-relative for up to 112 cases and stack-pushing
4396 target addresses loaded with offset from dptr for up to 256 cases.
4398 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4399 * src/mcs51/main.c: adapted constants for switch table generation

4423 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4424 to call when a stack overflow occurs,
4425 * (malloc.h): added CVS Id tag,
4426 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4428 * added libc directory. The current version of LibC contains string
4429 functions, ctype functions and macros and some functions of the
4430 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4431 be extensively tested in the future. Standard disclaimer here.
4432 Library is not automatically build yet. But one can build it by
4433 invoking 'make' inside the libc directory.
4434 * added ADC library under libio. Preliminary version yet.
4436 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4443 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4444 * (pic16_storeForReturn): optimized return of 0,
4445 * (genCmp): experimental code for new genCmp which uses PIC18's
4446 special compare&skip instructions. Initial tests fail some times
4447 with variables grater than 1 byte in size, so new code is disabled,
4448 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4450 * (genCast): began a fix to optimize the casting of a bit to another
4451 bit, now assigning a bitfield to another bitfield will fail, sorry,
4452 * src/pic16/main.c: disabled the use of lr-support feature,
4453 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4454 * added some function prototypes, added function _debugf prototype,

4456 bits with offset (case PO_GPR_BIT),
4457 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4459 * (isBankInstruction): modified to return 0 for no banking instruction,
4460 and 1 for banking instruction,
4461 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4462 caused stop processing pCodes after a inline assembly block,
4463 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4464 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4465 registers when it shouldn't,
4466 * src/pic16/ralloc.c (allocReg): add preliminary support for
4467 supporting a limited set of temporary registers,
4469 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4471 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4472 genDataPointerSet): ensure assignments always copy in MSB to LSB
4474 (loadRegFromAop): recognize CLRH optimization,
4475 (genFunction): optimize RECEIVE iCodes in reentrant functions
4477 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4479 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7474 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7476 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7477 loaded with the linker search paths (-L arguments) and the libraries
7478 to be linked with the current source (-l arguments). Changes
7479 currently will affect only the pic16 port.
7480 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7481 include path the port specific paths and port specific libraries,
7482 * gplink command now contains the $3 argument,
7483 * src/pic16/device.h,
7484 * src/pic16/device.c,: structure PIC_device is made public and
7485 renamed to PIC16_device, the same for variable Pics which is renamed

7498 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7500 Documenting changes from previous commits.
7501 * configure.in (version 1.56),
7502 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7503 when generating output files to configure the pic16 library,
7504 but now I've commented it out, since gputils aren't installed in the
7505 SF compile farm, so library won't compile
7507 * device/lib/Makefile.in (version 1.56): initially I've added in
7508 target 'all' the prerequestive 'model-pic16' so it compiled the
7509 pic16 library, but now I've commented it out for the same reasons
7511 * added targets 'model-pic16' and 'objects-pic16' to compile the
7513 * added target 'port-specific-objects-pic16' to handle the
7514 generated libraries and copy them into the build/ directory
7515 * added target 'clean-intermediate-pic16' to clean intermediate
7516 files into pic16 directory
7517 * in target 'installdirs' added line to create directory pic16 in
7518 the installation path
7520 * device/include/Makefile.in (version 1.11): in target 'install'
7521 added lines to copy all header files to installation path,
7522 * in target 'installdirs' added line create directory for pic16
7523 headers in the installation path

7538 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7539 option so that it actually works. Made it specific to the z80, since
7540 the gbz80 doesn't have these kinds of I/O ports.
7542 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7544 * device/include/z180.h,

7557 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7559 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7560 changed interrupt vector table generation to only emit declared vectors.
7561 * device/include/Makefile.in: added missing backslash
7562 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7564 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7566 Mainly changes to support compilation of the device libraries
7567 * src/pic16/device.c: stack is allocated via symbol and not
7568 via literal number. The symbol is placed in the corresponding
7569 position of the data ram
7570 * (pic16_dump_section): relocatable and absolute uninitialized
7571 data are now emitted in sorted order to reduce section naming,
7572 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7573 weren't marked as being in the access bank,
7575 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7577 Added portion of GNU PIC Library under the directory
7578 device/include/pic16 and device/lib/pic16. These files
7579 contain the declarations of SFRs for the PIC18Fxx2 devices.
7580 The directory is initialized via configure from toplevel.
7582 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7584 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7585 the spilllocations to be compared correctly
7587 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7589 * src/SDCCast.c (decorateType): fixed bug introduced today
7591 2004-01-12 Borut Razem <borut.razem AT siol.net>
7593 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

7596 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7598 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7599 in simpler and even better code
7601 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7603 * src/SDCCicode.c (operandOperation): fixed bug #874819

7609 * doc/sdccman.lyx: Moved and added some sections, small changes
7610 all over. Telling LaTeX to be less strict with word spacing
7611 to better keep the right margin. Changed some notes about
7612 maintainance of the ports in section 3.2.1 - is it OK like this?
7614 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7651 UPPER for immediate operands,
7652 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7654 * src/pic16/peeph.def: all peepholes with movff are commented out,
7655 because there is a problem in the pcode peep optimizer,
7656 * src/pic16/ralloc.c: the register allocator can now reuse local
7657 function symbols for another function. This saves register usage.
7658 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7660 Added file src/pic16/NOTES with information about program writing on
7661 the current port version.

7693 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7696 * src/z80/main.c: added missed needLinkerScript flags (more than
7697 one port structure defined in these file)
7698 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7714 needLinkerScript flag
7716 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7717 * src/pic/glue.c: added variable udata_section_name to
7718 override default uninitialized data segment definition for

7721 directive when no overlay data exist
7722 * (picglue): modified to emit uninitialized data segment
7723 according to udata_section_name

7728 arguments via -W option
7729 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7730 object file from '.rel' to '.o' in port->linker structure,
7731 changed size of fptr from 2 to 3 in port structure
7733 2004-01-07 Borut Razem <borut.razem AT siol.net>
7735 * support/scripts/sdcc.nsi: update PATH
7736 * support/scripts/sdcc.ico: craeted

7749 include information about variables allocated to the overlay
7752 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7754 * as/mcs51/lkmain.c: Help about -Y option

7766 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7768 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7769 (default behaviour).
7771 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7773 A python script to validate compiler diagnostic messages. It can be
7774 used to verify that sdcc complains about bad c source code and
7775 gives a good location of the error.
7776 * support/valdiag/Makefile,
7777 * support/valdiag/valdiag.py,
7778 * support/valdiag/tests/*
7780 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7793 * src/common.h: added ifndef/define/endif macros
7794 around the header file.
7795 Bug reported from Jesus Calvino-Fraga
7797 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7799 * sdcc.spec: updated
7800 * device/include/Makefile.in: don't install CVS directories
7801 * device/lib/Makefile.in: added removal of CVS directories after install
7802 * doc/Makefile: fixed install, added local_icons
7803 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7804 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7805 * src/ds390/gen.c (genRightShift): fixed bug #870788
7806 * src/SDCCast.c (decorateType): fixed bug #870781
7808 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7810 PIC16 port related changes:
7811 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7812 added variable stackPos,
7814 * gen.c: genCall, assignResultValue: added support for
7815 pushing/retrieving function parameters to/from stack,
7816 genFunction,genEndFunction: setup stack frame for the
7818 genAddrOf: will be changed according to bug 863624
7820 * added files genutils.c and genutils.h which contain gen*
7821 debugged and optimised functions extracted from gen.c
7823 * glue.c: added variable 'externs' which holds extern symbols,
7824 pic16emitRegularMap: is modified to properly handle relocatable
7825 symbols under the new scheme,
7826 pic16createInterruptVect: is modified
7827 pic16printPublics: is modified to emit 'global' assembler directives,
7828 added pic16_printExterns to print extern symbols,
7829 pic16glue: initializes stack/frame pointer in the beginning of
7830 the assembly output. Temporary hack, will be corrected later,
7831 because gplink yet does not support stack and SDCC does not
7832 yet support a type of crt0.o object to create the final binary.
7834 * Removed many lines that contain 8051 legacy code.
7835 * The code is finally placed under a 'code' directive.
7836 * Added port specific options.
7838 * _process_pragma: simplified since now we do not need *special*
7839 include file to define SFR registers. But a separate header
7840 will be needed. This will be developed later.
7841 * _pic16_parseOptions: added, parses port specific options:
7842 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7843 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7844 --preplace-udata-with=
7846 * _pic16_setDefaultOptions: modified to initialize section names,
7847 but hack is temporarly out of order since it needs improvement.
7848 * _pic16_genAssemblerPreamble: configuration words are emitted by
7849 their address instead of their name. This part is incomplete and
7850 supports only the 18Fxx2 devices. Other devices will emit an error
7851 during assembly since they do not contain the same set of config
7853 * _pic16_genIVT: is modified,
7855 * pcode.c: added definitions for some hardware registers that are needed
7857 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7858 All PCI entries are updated. Now LFSR is supported.
7859 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7860 * added pic16_newpCodeOpLit2 to support instructions with
7861 two literal arguments
7862 * pic16_pCode2str: corrected code that emits assembler instructions
7863 with two literal operands and those that have an access bit modifier
7864 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7865 this fixes a bug which caused some labels to be lost, when an
7866 assembler directive was added, i.e. banksel,
7867 * pic16_FixRegisterBanking: improved logic that causes the insertion
7869 * InlineFunction: functions that are called once, are not any more
7870 inlined. This can be a port option in the future,
7872 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7874 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7875 hold the corresponding uninitialized symbols,
7876 * pic16_allocProcessorRegister: registers have explicit marked the
7878 * pic16_allocInternalRegister: registers are explicit marked as
7880 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7881 processing list, so bit registers were lost,
7884 * ralloc.h: added field 'accessBank' and original symbol operand
7885 in register definition,
7886 * removed the field isMapped from register definition,
7888 ** Several functions have been removed from various sources:
7889 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7890 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7891 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7892 pic16_assignRelocatableRegisters
7894 ** others have been introduced:
7895 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7896 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7898 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7900 * support/scripts/inc2h.pl: changed definition of BIT_AT
7901 to emit 'sbit at' instead of 'bit at'. This was a request.
7903 PIC16 port related preliminary changes:
7904 * gen.c: prefixed function popRegFromString with
7905 pic16_ and all references to it corrected
7906 * pcode.c: all pic16_pc_* hardware registers prefixed
7907 with underscore (_),
7908 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7909 * ralloc.c: newReg(): when register is REG_SFR then
7910 set address to rIdx,
7911 pic16_allocProcessorRegister(): marks register wasUsed=0
7912 pic16_writeUsedRegs(): added a call to assign processor
7913 registers via pic16_assignFixedRegisters
7915 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7917 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7918 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7919 variables in unused register banks. Also the SSEG is placed
7920 wherever there is enough space for it, and IDATA can be anywhere
7921 in internal RAM. For now compile using -Wl-Y[stack_size].
7922 The mem file is different for this option as well, since it
7923 makes no sense of talking about DSEG lenght.

8918 and JUMPTABLE iCodes properly now (worked by accident before)
8919 * src/mcs51/gen.c (leftRightUseAcc),
8920 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8921 iCode properly now. Use getSize instead of nRegs since a & b
8922 aren't part of the nRegs tally.
8924 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8926 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8927 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8928 before instructions that use the _STATUS register
8930 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8932 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8933 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8934 fetching of the pointer
8935 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8936 copied from genNearPointerSet()
8937 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8938 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8939 If they pop r0/r1 they must be called in the opposite order than aopOp().
8940 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8941 (resp. --stack-auto), prepared for --xstack
8943 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8947 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8949 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8950 these ports have their own __sdcc_external_start()
8952 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8954 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8955 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8956 type for bits was changed. It resulted in bit variables becoming
8957 global, which is not permitted in PIC 14 assembly output.
8959 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8961 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8963 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8965 Z80 and MCS51 linkers complaint if a public symbol is defined
8966 in more than one library module:
8970 * as/mcs51/Makefile.in
8972 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8974 A few small changes that speed up the peephole optimizer.
8978 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8980 Try to make the peephole optimizer smarter by maintaining
8981 an association between the assembly source code and the
8982 iCodes that originated them. Put this information to use
8983 with a new peephole rule condition "notVolatile" so that
8984 the rules can be aggressive yet still safe.
8989 * src/mcs51/peeph.def
8991 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8995 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8996 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8997 if the left or right operand symbols have the accuse flag set.
8999 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9001 Changed the type of the result of the ! (NOT) operator to char;
9002 previously it returned the same type as the source. This allows
9003 us to eliminate all the genFloatNot functions (all of its target
9004 implementations were very buggy) since !float can use the same
9007 * src/SDCCicode.c (ast2iCode): ! returns char
9008 * src/mcs51/gen.c (genNot, genNotFloat),
9009 * src/ds390/gen.c (genNot, genNotFloat),
9010 * src/z80/gen.c (genNot, genNotFloat),
9011 * src/pic/gen.c (genNot, genNotFloat),
9012 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9014 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9016 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9017 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9018 during interrupts. Ensure WSAVE is located at a shared bank address.
9019 2. Fixed page selection in some places
9020 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9021 the registers name strings.
9022 4. Fixed "signed / unsigned compare" compiler warnings.
9023 5. The PIC port manages its own allocation of the general purpose
9024 registers, but makes no attempt to reuse them. As a result when
9025 compiling it soon runs out of general purpose registers. Some
9026 additional code was added to the files pcode.c and device.c to walk
9027 through the function call tree and rename the registers so that they
9037 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9038 genPlus() & genMinus() when the result is the same as left or right

9044 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9046 Made bitfield a distinct type from bit so that bitfields
9047 convert as per ANSI C and bits retain their traditional
9048 boolean style behaviour. Implemented bitfield support in
9056 * src/ds390/gen.c: bit v bitfield split
9057 * src/z80/gen.c: New support for bitfields
9058 * support/regression/tests/bitfields.c: reenabled z80,
9061 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9063 Rules 246.x, 247.x relate to bitfields, the others speed up
9064 access to xdata mapped I/O devices.
9066 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9068 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9070 Cleaned up genPackBits and genUnpackBits and added two helper
9071 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9072 for literal assignments in genPackBits (thanks to Frieder for
9078 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9080 Fixed bug #748310 (pointer to function type mishandled when the
9081 function name is omitted). Also fixed a SIGSEGV when a function
9082 attribute (reentrant, etc) is used on a non-function or on a
9083 function but misplaced before the parameter list.
9085 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9087 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9088 * support/Util/SDCCerr.h,
9089 * support/Util/SDCCerr.c: Added func attr misuse error msg

9110 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9112 Made the constant following the "interrupt" keyword optional. If
9113 omitted, the function will not automatically be given an entry
9114 in the interrupt vector table (similar to #pragma NOIV, but
9115 less syntacticly kludgy). The interrupt number is also now
9116 range checked. Also fixed a bug in the high order bit example
9123 * support/Util/SDCCerr.c
9124 * support/Util/SDCCerr.h
9127 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9130 * src/SDCCicode.c (operandOperation): rewritten some ops
9131 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9132 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9134 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9135 be re-activated by defining REDUCE_LITERALS)
9136 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9137 unsigned, but are signed by default
9138 * src/SDCCval.c (constVal): rearranged
9139 * src/SDCCval.c (valMod): preliminary fix
9140 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9183 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9184 * src/SDCCval.c (valDiv, valMod): fixed signdness
9185 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9186 signedness of modulo, left and right shift

9592 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9593 the regression tests I'm not brave enough to enable 245.b, 245.c
9594 * doc/sdccman.lyx: added latex preamble for hyperref package.
9595 Using pdflatex this will give you a hyperlinked pdf file with
9596 bookmarks. (prepend '%' before /usepackage if this breaks something)

9612 Applied patch from bug 737905 (renamed yylineo to mylineno):
9619 * src/pic16/pcode.c: Cleaned warnings
9620 * src/pic16/pcodeflow.c: Cleaned warnings
9621 * src/pic16/pcoderegs.c: Cleaned warnings

9637 it can be defined with CFLAGS when running configure
9638 * src/SDCCmain.c: fixed compiling + linking with object files
9640 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9643 added --disable-pic16-port
9644 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9645 * src/SDCCmain.c: linkOptions is changed to set *,
9646 added if/endif conditional macros to remove options help
9647 messages from optionsTable when a port is not configured, added
9648 support for the PIc16 port in the ports table, when executing
9649 the compiler with no port specified on command line, a default
9650 port is selected with the new macro DEFAULT_PORT which is
9651 defined in port.h, in setDefaultOptions() linkOptions is removed
9652 from initialization assignment, since now it is a set,
9653 parseCmdLine uses setParseWithComma for linkOptions, in
9654 linkEdit() linkOptions are accessed with new function indexSet()
9655 which returns the i'th item of a set variable. See SDCCset.c, in
9656 linkEdit() when calling buildCmdLine(), added linkOptions as
9657 last argument. Now users can pass arguments to gplink via the
9658 -Wl option, main() uses pic16glue() to glue up pic16 programs

9670 * src/pic16/glue.c: commented out some error producing lines
9671 * src/pic16/main.c: __config directives are commented out to stop
9672 gpasm complaining and test the linkage with gplink, _linkCmd and
9673 _asmCmd changed to be more gplink and gpasm friendly
9674 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9675 produced an error when parsed, peep rule 12 is added to utilize
9676 movff, but it is commented out since the pCode does not support
9677 yet a command with 2 address arguments
9679 2003-05-18 <johan AT balder>
9681 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9682 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9708 2003-05-11 Borut Razem <borut.razem AT siol.net>
9710 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9711 the path of bin directory, so that PATH is the only env. variable, which has to be set
9712 in case of standard installation.
9713 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10809 overlaying area for it (uses RegBankUsed[4]).
10811 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10812 bank zero as used by default. By default aslink locates the stack
10813 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10814 the creation of the .mem file. Delegates the allocation of data area
10815 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10816 the begining of the stack area to aslink.
10818 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10819 glue() in SDCCglue.c creates an area for it.
10821 2002-09-03 Borut Razem <borut.razem AT siol.net>
10822 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10823 sdcc/src/pic/glue.c:
10824 introduced atexit() handler for teporay files removal in case of
10825 errors, assertions, ...
10827 2002-08-29 Borut Razem <borut.razem AT siol.net>
10828 * sdcc/support/cpp2/auto-host_vc_in.h:
10829 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10830 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10831 Maybe there is a similar problem with BORLANDC? It should be checked!
10833 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10834 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10835 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10836 was not executed, and the compiler (cl) launched a warning:
10837 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10839 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10840 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10842 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10843 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10845 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10846 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10847 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10848 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10849 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10850 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10851 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10852 - added Release configuration in VS projects
10853 - review of compiler an linker options
10854 - VC .exe files are generated in bin_vc directory, not to interfere
10855 with binaries generated from other projects (cygwin, mingw, bcc ...)
10857 * sdcc/src/yacc.dsp: added
10859 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10860 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10861 and insert the version number definitions from .version
10863 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10865 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10866 added - genarate auto-host.h using auto-host_vc_in.h as template
10869 removed from CVS, generated automatically
10871 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10872 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10874 2002-08-11 Borut Razem <borut.razem AT siol.net>
10875 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10877 2002-08-10 Borut Razem <borut.razem AT siol.net>
10878 * src/SDCCmain.c (main):
10879 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10880 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10881 The consequence was that some temporary files were not removed.
10884 unification of code in functions tempfilename() and tempfile():
10885 function tempnam() is defined in Visual Studio 6.0 and .NET
10887 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10889 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10890 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10891 - removed compiler command line option /WX: Treats all warnings as errors
10892 - update a list of source files, included into the project
10894 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10895 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10896 changed project type to Generic Project so that can be correcly converted to VS.NET project
10898 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10900 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10902 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10904 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10905 added return 0 statements after assert() to make compiler happy
10907 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10908 added newline in the def file to keep MSC compiler satisfied
10910 * sdcc/src/z80/gen.c:
10911 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10912 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10913 - solved MSC error in function aopDump()
10915 * sdcc_vc.h: define PREFIX as "\\sdcc"
10917 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10918 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10966 Added -p option. Allows port dependent processor to be specified.
10969 Initialized the new field char *Processor field to NULL in all ports
10972 Compiler generated registers for interrupt context saving
10973 were not getting allocated.
10975 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10978 Fixed left shift. Will promote the left side of a left shift
10979 if a) left shifting more than size of operand or b) when assigned
10980 to something size > size of left side

11090 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11092 * sdcc/src/SDCCloop.c:
11093 Previous fix was not good. basic blocks that have "break" or "return" are
11094 not really partof a loop , but live ranges used in these blocks should
11095 be live thru the entire loop, so set partOfLoop but don't add them to
11098 2002-02-21 <johan AT FRIJA>
11100 * src/SDCCcse.c: fixed bug #514308
11102 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
