2035 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2037 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2038 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2040 One basic decision: e.g. src/clean.mk includes further files. In order
2041 to make this work there are two solutions:
2042 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2043 run configure on them. This way they can use
2044 'include $(srcdir)/port-clean.mk'
2045 - always include clean.mk by the Makefile at the same level. To avoid
2046 that `make clean` tries to include and build Makefile.dep the
2047 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2048 implemented, because now even `make uninstall` doesn't create
2049 Makefile.in. clean.mk could be eliminated by pasting it in
2052 * debugger/mcs51/Makefile.in: build own objects from library sources
2053 (SLIB, SDCC) in current directory
2055 * configure, configure.in: renamed --disable-device-lib-build in
2056 --disable-device-lib; added --enable-doc, the required tools are
2057 searched by configure; added result message; the toolchain for the
2058 belonging ports are now only built, if the port is enabled.
2060 * support/regression/*: all output is written in directory gen, because
2061 the fwk and ports directories don't livet in the build tree using vpath
2063 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2064 --disable-device-lib, added --enable-doc, added section VPATH
2066 * sim/ucsim/configure.in,
2067 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2068 z80 are enabled by default
2070 2006-04-24 Raphael Neider <rneider AT web.de>
2072 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2073 to config word, "pic14_"-prefixed some extern functions
2074 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2075 config word has been found
2076 * src/pic/device.h: added prototypes
2077 * src/pic/pcode.c: added "pic14_"-prefix where needed
2078 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2080 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2083 (pic14createInterruptVect): moved generating __config directives away

2095 (pCodeRegOptimizeRegUsage): fixed typo in comment

2099 * device/examples/main8051.c: deleted - it was removed from CVS

2341 implemented patch 1120823 Thanks to Willy De la Court (normal
2342 interrupts need an interrupt number now if they are made critical),
2343 and enabled nesting of critical functions though not for gbz80
2344 (genCritical, genEndCritical): added functions
2345 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2346 * src/z80/mappings.i: added "ei" to all mappings

2358 the left operand is shorter than the result (c* = lit-c* + int),
2360 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2363 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2365 * src/.version: increased version number to 2.5.5
2366 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2367 linking is done manually in pic16 port's _linkEdit,
2368 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2369 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2370 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2371 allocate asmop as AOP_ACC,
2372 (aopForRemat): added parameter 'bool result' in function declaration,
2373 (pic16_aopGet): return AOP_ACC when accessing WREG,
2374 (pic16_popGetTempReg): minor modification,

2385 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2386 call to allocReg, not by manually allocating a new one,
2387 (pic16_assignRegisters): now before going through the register
2388 allocating functions mark all registers as free. This eliminates some
2389 side effects resulting from peephole parser done earlier in the backbone
2391 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2449 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2450 which dumps before the function entry point a data byte which represents
2451 the number of the local variables used by the specified function, added
2452 'xinst' for initial support for Extended Instruction Support,
2453 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2454 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2455 port->fun_prefix anymore (may change later),
2456 (genFunction, genEndFunction): do not store/restore local registers for
2457 _main (this should take care the --main-return command line option in
2459 (genOr): removed some legacy pic-port instructions,
2460 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2461 performing operations with SFR's causes data to be written more than
2462 once to each SFR. Perhaps SFRs should be handled in special cases...
2463 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2465 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2466 into account for stack starting position,

2468 --extended or -y for Extended Instruction Support,
2469 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2470 (deassignLRs): *** perhaps the most important change, old 'for' code
2471 (commented out for reference), didn't account for some registers which
2472 were left marked 'not free' after a pointer operation. The change
2473 reduces register usage a lot in some cases
2475 2006-03-04 Borut Razem <borut.razem AT siol.net>

4740 on rIfx (genCmp was broken)
4742 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4744 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4745 * src/z80/main.c (_keywords[]),
4746 * src/SDCCglobal.h (struct options),
4748 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4749 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4750 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4751 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4752 always available in leading double underscore form. The C99 support is
4753 mostly missing, but it's a start.
4754 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4755 reserved identifier "__data".
4757 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4759 * src/mcs51/peeph.def: fixed bug 1170013

4767 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
4770 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4772 * src/port.h (struct PORT),

4803 2005-03-20 Borut Razem <borut.razem AT siol.net>
4805 * support/scripts/inc2h.pl: WIN32 port

4809 * device/lib/makefile.in: added abs.c and labs.c
4811 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4813 * device/include/stdint.h: added
4814 * device/lib/abs.c: added

4833 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4835 * device/lib/printf_large.c: removed inline assembly for portability and
4836 readability. Use printf_fast if speed or size are more important.
4837 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4838 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4840 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4842 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4843 prevent compiler warning
4845 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4847 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4848 moved to level 0 and declared as static. Also they are explicit
4849 placed in access bank. This was necessery because some times they
4850 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4851 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4852 optimizations. Currently only compare to unsigned char is implemented,
4853 * src/pic16/gen.c: added fReturnIdx array,
4854 * (struct resolvedIfx) is moved to gen.h and made public,
4855 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4856 * (aopForSym): added an optimization to directly store in stack of
4857 the operand of a SEND iCode,
4858 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4859 but as registers instead (AOP_REG) using the fReturnIdx array,
4860 * (pic16_freeAsmop): remove the freed register from the
4861 _G.sregsAlloc field,
4862 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4863 a compare of 'WREG',
4864 * (pic16_popGetTempRegCond): changed function prototype, now
4865 function takes also a bitVector argument v which holds the current
4866 set of registers that are allocated for stack access by aopForSym,
4867 registers allocated in aopForSym for accessing stack symbols are not
4868 any more part of the functions usedRegs field,
4869 * (genCall): some times aopOp is called for a stack variable to be
4870 send, aopForSym might perform the push, if this is true make sure
4871 that genCall doesn't push the variable twice by testing _G.resDirect,
4872 * (genFunction): changed testing for unspecified interrupt number
4873 from 256 to INTNO_UNSPEC,
4874 * modified selection scheme of frame pointer generation. Previously
4875 if function did use local registers a frame pointer was generated,
4876 now a frame pointer is generated only if function has arguments
4877 (that need PLUSW2 register access), or has stack arguments, or the
4878 compiler is not instructed to omit the frame pointer,
4879 * (genEndFunction): before restoring local registers that were saved
4880 in the function preamble, also restore the registers that *might*
4881 have been allocated for stack access,
4882 * (genRet): removed some old comments,
4883 * (genCmp, the active (RN's) version): added a call to the
4884 pic16_genCmp_special function to perform the compare with a more
4885 robust and optimized way,
4886 * (genInline): a feature has been added in inline code generation,
4887 which allows a wildcard variable substitution when writing inline
4888 assembly. Code is incomplete and experimental therefore undocumented,
4889 * (genCast): changed order of aopOp for result and right to allow
4890 aopForSym to directly load the result if possible,
4891 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4892 perform an optimized compare on some selected special occasions,
4893 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4894 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4895 generate an IVT any more,
4896 * src/pic16/main.c (pic16_optionsTable): added command line option
4898 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4899 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4901 * src/pic16/NOTES: Raphael Neider added in list of active developers
4902 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4903 jumptable_end to prevent bug #,
4904 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4905 inCond and outCond fields,
4906 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4907 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4908 turn off register spilling,
4909 * (packRegsForOneUse): synced with other ports' versions although it
4910 is not used currently,
4911 * (pic16_packRegisters): added an optimization while reading
4912 structure bitfields, some registers may be saved (malloc code is
4913 decreased by 80 bytes)
4915 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4917 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4918 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4919 this can be optimized more?
4921 2005-03-10 Raphael Neider <rneider AT web.de>
4923 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4924 genNearPointerGet): (hopefully) fixed access to bitfields via
4925 pointers (p->bitN = x; and x = p->bitN; failed)
4927 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5104 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5105 (sizeof(sectNames) changed to sizeof(sectName))
5106 Both patches fix segfaults under MinGW.
5108 2005-01-23 Raphael Neider <rneider AT web.de>

5112 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5113 of (byte sized) temporaries (assign them to WREG for now)
5114 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5115 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5116 this might fix SIGSEGVs on MinGW...
5117 * src/SDCCopt.c (killDeadCode): restored original behaviour
5118 (volatile operands might get thrown away though)
5120 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5122 * src/pic16/gen.c: fixed bug #1106975,

5583 * src/pic16/device.h,
5584 * src/pic16/genarith.c,
5587 * src/pic16/pcode.c: applied patches #1068154 and #1070213
5589 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
5591 Large cummulative patch for pic16 port.
5592 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5593 to call when a stack overflow occurs,
5594 * (malloc.h): added CVS Id tag,
5595 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5597 * added libc directory. The current version of LibC contains string
5598 functions, ctype functions and macros and some functions of the
5599 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5600 be extensively tested in the future. Standard disclaimer here.
5601 Library is not automatically build yet. But one can build it by
5602 invoking 'make' inside the libc directory.
5603 * added ADC library under libio. Preliminary version yet.
5605 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5606 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5607 aopForRemat() now and not by pic16_aopOp(),
5608 * (pic16_popGetTempReg): removed warning messgae when allocating
5609 temporary registers, its a buggy feature and will be removed,
5610 * (pic16_popGet): set register instance field in AOP_CRY,
5611 * (pic16_outBitC): fixed for results in size greater than 1,
5612 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5613 * (pic16_storeForReturn): optimized return of 0,
5614 * (genCmp): experimental code for new genCmp which uses PIC18's
5615 special compare&skip instructions. Initial tests fail some times
5616 with variables grater than 1 byte in size, so new code is disabled,
5617 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5619 * (genCast): began a fix to optimize the casting of a bit to another
5620 bit, now assigning a bitfield to another bitfield will fail, sorry,
5621 * src/pic16/main.c: disabled the use of lr-support feature,
5622 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5623 * added some function prototypes, added function _debugf prototype,
5624 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5625 bits with offset (case PO_GPR_BIT),
5626 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5628 * (isBankInstruction): modified to return 0 for no banking instruction,
5629 and 1 for banking instruction,
5630 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5631 caused stop processing pCodes after a inline assembly block,
5632 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5633 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5634 registers when it shouldn't,
5635 * src/pic16/ralloc.c (allocReg): add preliminary support for
5636 supporting a limited set of temporary registers,
5638 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5640 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5641 genDataPointerSet): ensure assignments always copy in MSB to LSB
5643 (loadRegFromAop): recognize CLRH optimization,
5644 (genFunction): optimize RECEIVE iCodes in reentrant functions
5646 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5648 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5649 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5651 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

8643 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8645 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8646 loaded with the linker search paths (-L arguments) and the libraries
8647 to be linked with the current source (-l arguments). Changes
8648 currently will affect only the pic16 port.
8649 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8650 include path the port specific paths and port specific libraries,
8651 * gplink command now contains the $3 argument,
8652 * src/pic16/device.h,
8653 * src/pic16/device.c,: structure PIC_device is made public and
8654 renamed to PIC16_device, the same for variable Pics which is renamed

8669 Documenting changes from previous commits.
8670 * configure.in (version 1.56),
8671 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8672 when generating output files to configure the pic16 library,
8673 but now I've commented it out, since gputils aren't installed in the
8674 SF compile farm, so library won't compile
8676 * device/lib/Makefile.in (version 1.56): initially I've added in
8677 target 'all' the prerequestive 'model-pic16' so it compiled the
8678 pic16 library, but now I've commented it out for the same reasons
8680 * added targets 'model-pic16' and 'objects-pic16' to compile the
8682 * added target 'port-specific-objects-pic16' to handle the
8683 generated libraries and copy them into the build/ directory
8684 * added target 'clean-intermediate-pic16' to clean intermediate
8685 files into pic16 directory
8686 * in target 'installdirs' added line to create directory pic16 in

8707 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8708 option so that it actually works. Made it specific to the z80, since
8709 the gbz80 doesn't have these kinds of I/O ports.
8711 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8713 * device/include/z180.h,

8737 via literal number. The symbol is placed in the corresponding
8738 position of the data ram
8739 * (pic16_dump_section): relocatable and absolute uninitialized
8740 data are now emitted in sorted order to reduce section naming,
8741 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8742 weren't marked as being in the access bank,
8744 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8746 Added portion of GNU PIC Library under the directory
8747 device/include/pic16 and device/lib/pic16. These files
8748 contain the declarations of SFRs for the PIC18Fxx2 devices.
8749 The directory is initialized via configure from toplevel.
8751 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8753 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8754 the spilllocations to be compared correctly

8779 all over. Telling LaTeX to be less strict with word spacing
8780 to better keep the right margin. Changed some notes about
8781 maintainance of the ports in section 3.2.1 - is it OK like this?
8783 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8821 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8823 * src/pic16/peeph.def: all peepholes with movff are commented out,
8824 because there is a problem in the pcode peep optimizer,
8825 * src/pic16/ralloc.c: the register allocator can now reuse local

8827 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8829 Added file src/pic16/NOTES with information about program writing on
8830 the current port version.

8862 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8865 * src/z80/main.c: added missed needLinkerScript flags (more than
8866 one port structure defined in these file)
8867 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8889 * (pic14emitOverlay): modified to emit a commented overlay segment
8890 directive when no overlay data exist
8891 * (picglue): modified to emit uninitialized data segment
8892 according to udata_section_name

8902 2004-01-07 Borut Razem <borut.razem AT siol.net>
8904 * support/scripts/sdcc.nsi: update PATH
8905 * support/scripts/sdcc.ico: craeted

8912 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8914 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8916 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8918 include information about variables allocated to the overlay
8921 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8923 * as/mcs51/lkmain.c: Help about -Y option

8935 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8937 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8938 (default behaviour).
8940 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8942 A python script to validate compiler diagnostic messages. It can be
8943 used to verify that sdcc complains about bad c source code and
8944 gives a good location of the error.
8945 * support/valdiag/Makefile,
8946 * support/valdiag/valdiag.py,
8947 * support/valdiag/tests/*
8949 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8951 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8962 * src/common.h: added ifndef/define/endif macros
8963 around the header file.
8964 Bug reported from Jesus Calvino-Fraga
8966 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8968 * sdcc.spec: updated
8969 * device/include/Makefile.in: don't install CVS directories
8970 * device/lib/Makefile.in: added removal of CVS directories after install
8971 * doc/Makefile: fixed install, added local_icons
8972 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8973 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8974 * src/ds390/gen.c (genRightShift): fixed bug #870788
8975 * src/SDCCast.c (decorateType): fixed bug #870781
8977 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8979 PIC16 port related changes:
8980 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8981 added variable stackPos,
8983 * gen.c: genCall, assignResultValue: added support for
8984 pushing/retrieving function parameters to/from stack,
8985 genFunction,genEndFunction: setup stack frame for the
8987 genAddrOf: will be changed according to bug 863624
8989 * added files genutils.c and genutils.h which contain gen*
8990 debugged and optimised functions extracted from gen.c
8992 * glue.c: added variable 'externs' which holds extern symbols,
8993 pic16emitRegularMap: is modified to properly handle relocatable
8994 symbols under the new scheme,
8995 pic16createInterruptVect: is modified
8996 pic16printPublics: is modified to emit 'global' assembler directives,
8997 added pic16_printExterns to print extern symbols,
8998 pic16glue: initializes stack/frame pointer in the beginning of
8999 the assembly output. Temporary hack, will be corrected later,
9000 because gplink yet does not support stack and SDCC does not
9001 yet support a type of crt0.o object to create the final binary.
9003 * Removed many lines that contain 8051 legacy code.
9004 * The code is finally placed under a 'code' directive.
9005 * Added port specific options.
9007 * _process_pragma: simplified since now we do not need *special*
9008 include file to define SFR registers. But a separate header
9009 will be needed. This will be developed later.
9010 * _pic16_parseOptions: added, parses port specific options:
9011 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9012 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9013 --preplace-udata-with=
9015 * _pic16_setDefaultOptions: modified to initialize section names,
9016 but hack is temporarly out of order since it needs improvement.
9017 * _pic16_genAssemblerPreamble: configuration words are emitted by
9018 their address instead of their name. This part is incomplete and
9019 supports only the 18Fxx2 devices. Other devices will emit an error
9020 during assembly since they do not contain the same set of config
9022 * _pic16_genIVT: is modified,
9024 * pcode.c: added definitions for some hardware registers that are needed
9026 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9027 All PCI entries are updated. Now LFSR is supported.
9028 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9029 * added pic16_newpCodeOpLit2 to support instructions with
9030 two literal arguments
9031 * pic16_pCode2str: corrected code that emits assembler instructions
9032 with two literal operands and those that have an access bit modifier
9033 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9034 this fixes a bug which caused some labels to be lost, when an
9035 assembler directive was added, i.e. banksel,
9036 * pic16_FixRegisterBanking: improved logic that causes the insertion
9038 * InlineFunction: functions that are called once, are not any more
9039 inlined. This can be a port option in the future,
9041 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9043 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9044 hold the corresponding uninitialized symbols,
9045 * pic16_allocProcessorRegister: registers have explicit marked the
9047 * pic16_allocInternalRegister: registers are explicit marked as
9049 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9050 processing list, so bit registers were lost,
9053 * ralloc.h: added field 'accessBank' and original symbol operand
9054 in register definition,
9055 * removed the field isMapped from register definition,
9057 ** Several functions have been removed from various sources:
9058 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9059 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9060 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9061 pic16_assignRelocatableRegisters
9063 ** others have been introduced:
9064 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9065 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9067 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9069 * support/scripts/inc2h.pl: changed definition of BIT_AT
9070 to emit 'sbit at' instead of 'bit at'. This was a request.
9072 PIC16 port related preliminary changes:
9073 * gen.c: prefixed function popRegFromString with
9074 pic16_ and all references to it corrected
9075 * pcode.c: all pic16_pc_* hardware registers prefixed
9076 with underscore (_),
9077 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9078 * ralloc.c: newReg(): when register is REG_SFR then
9079 set address to rIdx,
9080 pic16_allocProcessorRegister(): marks register wasUsed=0
9081 pic16_writeUsedRegs(): added a call to assign processor
9082 registers via pic16_assignFixedRegisters
9084 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9086 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9087 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9088 variables in unused register banks. Also the SSEG is placed
9089 wherever there is enough space for it, and IDATA can be anywhere
9090 in internal RAM. For now compile using -Wl-Y[stack_size].
9091 The mem file is different for this option as well, since it
9092 makes no sense of talking about DSEG lenght.
9094 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9096 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9097 in certain cases, e.g. when ROM assignment, patch provided
9098 from Albert den Haan.
9100 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9645 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9647 Fixed a number of problems revealed by bug #827883.
9648 * src/SDCCloop.c (loopInvariants): Spill location of the
9649 result operand should be recomputed if extracted from
9650 a loop. Also, don't extract assignments of an iTemp
9652 * src/SDCCast.c (isConformingBody): loop reversal should
9653 not occur if the control variable is involved with a
9654 relational operator.

10143 A few small changes that speed up the peephole optimizer.
10147 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10149 Try to make the peephole optimizer smarter by maintaining
10150 an association between the assembly source code and the
10151 iCodes that originated them. Put this information to use
10152 with a new peephole rule condition "notVolatile" so that
10153 the rules can be aggressive yet still safe.
10158 * src/mcs51/peeph.def
10160 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10164 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

10168 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10170 Changed the type of the result of the ! (NOT) operator to char;
10171 previously it returned the same type as the source. This allows
10172 us to eliminate all the genFloatNot functions (all of its target
10173 implementations were very buggy) since !float can use the same
10176 * src/SDCCicode.c (ast2iCode): ! returns char
10177 * src/mcs51/gen.c (genNot, genNotFloat),
10178 * src/ds390/gen.c (genNot, genNotFloat),
10179 * src/z80/gen.c (genNot, genNotFloat),

10185 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10186 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10187 during interrupts. Ensure WSAVE is located at a shared bank address.
10188 2. Fixed page selection in some places
10189 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10190 the registers name strings.
10191 4. Fixed "signed / unsigned compare" compiler warnings.
10192 5. The PIC port manages its own allocation of the general purpose
10193 registers, but makes no attempt to reuse them. As a result when
10194 compiling it soon runs out of general purpose registers. Some
10195 additional code was added to the files pcode.c and device.c to walk
10196 through the function call tree and rename the registers so that they
10206 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10207 genPlus() & genMinus() when the result is the same as left or right

10213 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10215 Made bitfield a distinct type from bit so that bitfields
10216 convert as per ANSI C and bits retain their traditional
10217 boolean style behaviour. Implemented bitfield support in
10225 * src/ds390/gen.c: bit v bitfield split
10226 * src/z80/gen.c: New support for bitfields
10227 * support/regression/tests/bitfields.c: reenabled z80,
10230 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10232 Rules 246.x, 247.x relate to bitfields, the others speed up
10233 access to xdata mapped I/O devices.
10235 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10237 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10239 Cleaned up genPackBits and genUnpackBits and added two helper
10240 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10241 for literal assignments in genPackBits (thanks to Frieder for
10247 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10249 Fixed bug #748310 (pointer to function type mishandled when the
10250 function name is omitted). Also fixed a SIGSEGV when a function
10251 attribute (reentrant, etc) is used on a non-function or on a
10252 function but misplaced before the parameter list.
10254 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

10279 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10281 Made the constant following the "interrupt" keyword optional. If
10282 omitted, the function will not automatically be given an entry
10283 in the interrupt vector table (similar to #pragma NOIV, but
10284 less syntacticly kludgy). The interrupt number is also now
10285 range checked. Also fixed a bug in the high order bit example

10304 be re-activated by defining REDUCE_LITERALS)
10305 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10306 unsigned, but are signed by default
10307 * src/SDCCval.c (constVal): rearranged
10308 * src/SDCCval.c (valMod): preliminary fix

10761 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10762 the regression tests I'm not brave enough to enable 245.b, 245.c
10763 * doc/sdccman.lyx: added latex preamble for hyperref package.
10764 Using pdflatex this will give you a hyperlinked pdf file with
10765 bookmarks. (prepend '%' before /usepackage if this breaks something)

10814 * src/SDCCmain.c: linkOptions is changed to set *,
10815 added if/endif conditional macros to remove options help
10816 messages from optionsTable when a port is not configured, added
10817 support for the PIc16 port in the ports table, when executing
10818 the compiler with no port specified on command line, a default
10819 port is selected with the new macro DEFAULT_PORT which is
10820 defined in port.h, in setDefaultOptions() linkOptions is removed
10821 from initialization assignment, since now it is a set,
10822 parseCmdLine uses setParseWithComma for linkOptions, in
10823 linkEdit() linkOptions are accessed with new function indexSet()
10824 which returns the i'th item of a set variable. See SDCCset.c, in
10825 linkEdit() when calling buildCmdLine(), added linkOptions as
10826 last argument. Now users can pass arguments to gplink via the
10827 -Wl option, main() uses pic16glue() to glue up pic16 programs
10828 * src/SDCCpeeph.c: various changes to support pic16
10829 * src/SDCCset.c: added function void *indexSet(set *, int) to

10839 * src/pic16/glue.c: commented out some error producing lines
10840 * src/pic16/main.c: __config directives are commented out to stop
10841 gpasm complaining and test the linkage with gplink, _linkCmd and
10842 _asmCmd changed to be more gplink and gpasm friendly
10843 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10844 produced an error when parsed, peep rule 12 is added to utilize
10845 movff, but it is commented out since the pCode does not support
10846 yet a command with 2 address arguments
10848 2003-05-18 <johan AT balder>
10850 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10877 2003-05-11 Borut Razem <borut.razem AT siol.net>
10879 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10880 the path of bin directory, so that PATH is the only env. variable, which has to be set

11915 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11916 following files to include the previous two files: aslink.dsp,
11917 Makefile.aslink, Makefile.bcc, and Makefile.in.
11919 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11920 .adb instead of .cdb
11922 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11924 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the

11936 packRegsForAccUse() (bug 542397)
11937 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11938 multiple times and emitting the fetch operations more than once
11939 added aopGetUsesAcc() function to allow binary operators to
11940 fetch their operands in the correct order; made genMinus() emit
11941 compact code for X = LITERAL - Y

11951 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11952 Changes to aslink (All the changes are marked with 'JCF'):
11954 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11957 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11958 area BSEG. Also moves, if possible, the DATA area down into the internal
11959 ram so more space is available.
11961 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11964 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11965 not bytes. Function summary() which creates a memory usage summary
11966 file with extension .mem. Reports of overlaping stack and small stack
11967 size. If the space for the stack is less than 16 bytes aslink trows a
11970 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11971 the 8051. Option 'y' for memory summary output file.
11973 Changes to sdcc (All the changes are marked with 'JCF'):
11975 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11977 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11978 overlaying area for it (uses RegBankUsed[4]).
11980 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11981 bank zero as used by default. By default aslink locates the stack
11982 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11983 the creation of the .mem file. Delegates the allocation of data area
11984 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11985 the begining of the stack area to aslink.
11987 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11988 glue() in SDCCglue.c creates an area for it.
11990 2002-09-03 Borut Razem <borut.razem AT siol.net>
11991 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11992 sdcc/src/pic/glue.c:
11993 introduced atexit() handler for teporay files removal in case of
11994 errors, assertions, ...
11996 2002-08-29 Borut Razem <borut.razem AT siol.net>
11997 * sdcc/support/cpp2/auto-host_vc_in.h:
11998 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11999 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12000 Maybe there is a similar problem with BORLANDC? It should be checked!
12002 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12003 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12004 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12005 was not executed, and the compiler (cl) launched a warning:
12006 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12008 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12009 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12011 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12012 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12014 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12015 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12016 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12017 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12018 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12019 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12020 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12021 - added Release configuration in VS projects
12022 - review of compiler an linker options
12023 - VC .exe files are generated in bin_vc directory, not to interfere
12024 with binaries generated from other projects (cygwin, mingw, bcc ...)
12026 * sdcc/src/yacc.dsp: added
12028 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12029 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12030 and insert the version number definitions from .version
12032 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12034 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12035 added - genarate auto-host.h using auto-host_vc_in.h as template
12038 removed from CVS, generated automatically
12040 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12041 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12043 2002-08-11 Borut Razem <borut.razem AT siol.net>
12044 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12046 2002-08-10 Borut Razem <borut.razem AT siol.net>
12047 * src/SDCCmain.c (main):
12048 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12049 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12050 The consequence was that some temporary files were not removed.
12053 unification of code in functions tempfilename() and tempfile():
12054 function tempnam() is defined in Visual Studio 6.0 and .NET
12056 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12058 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12059 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12060 - removed compiler command line option /WX: Treats all warnings as errors
12061 - update a list of source files, included into the project
12063 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12064 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12065 changed project type to Generic Project so that can be correcly converted to VS.NET project
12067 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12069 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12071 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12073 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12074 added return 0 statements after assert() to make compiler happy
12076 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12077 added newline in the def file to keep MSC compiler satisfied
12079 * sdcc/src/z80/gen.c:
12080 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12081 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12082 - solved MSC error in function aopDump()
12084 * sdcc_vc.h: define PREFIX as "\\sdcc"
12086 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12087 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12259 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12261 * sdcc/src/SDCCloop.c:
12262 Previous fix was not good. basic blocks that have "break" or "return" are
12263 not really partof a loop , but live ranges used in these blocks should
12264 be live thru the entire loop, so set partOfLoop but don't add them to
12267 2002-02-21 <johan AT FRIJA>
12269 * src/SDCCcse.c: fixed bug #514308
12271 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
