2020 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2022 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2023 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2025 One basic decision: e.g. src/clean.mk includes further files. In order
2026 to make this work there are two solutions:
2027 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2028 run configure on them. This way they can use
2029 'include $(srcdir)/port-clean.mk'
2030 - always include clean.mk by the Makefile at the same level. To avoid
2031 that `make clean` tries to include and build Makefile.dep the
2032 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2033 implemented, because now even `make uninstall` doesn't create
2034 Makefile.in. clean.mk could be eliminated by pasting it in
2037 * debugger/mcs51/Makefile.in: build own objects from library sources
2038 (SLIB, SDCC) in current directory
2040 * configure, configure.in: renamed --disable-device-lib-build in
2041 --disable-device-lib; added --enable-doc, the required tools are
2042 searched by configure; added result message; the toolchain for the
2043 belonging ports are now only built, if the port is enabled.
2045 * support/regression/*: all output is written in directory gen, because
2046 the fwk and ports directories don't livet in the build tree using vpath
2048 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2049 --disable-device-lib, added --enable-doc, added section VPATH
2051 * sim/ucsim/configure.in,
2052 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2053 z80 are enabled by default
2055 2006-04-24 Raphael Neider <rneider AT web.de>
2057 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2058 to config word, "pic14_"-prefixed some extern functions
2059 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2060 config word has been found
2061 * src/pic/device.h: added prototypes
2062 * src/pic/pcode.c: added "pic14_"-prefix where needed
2063 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2065 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2067 (pic14emitRegularMap): ignore config words,
2068 (pic14createInterruptVect): moved generating __config directives away
2069 (picglue): have __config directives emitted

2079 fixes #1469504 and #1474602,
2080 (pCodeRegOptimizeRegUsage): fixed typo in comment

2326 implemented patch 1120823 Thanks to Willy De la Court (normal
2327 interrupts need an interrupt number now if they are made critical),
2328 and enabled nesting of critical functions though not for gbz80
2329 (genCritical, genEndCritical): added functions
2330 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2331 * src/z80/mappings.i: added "ei" to all mappings

2343 the left operand is shorter than the result (c* = lit-c* + int),
2345 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2348 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2350 * src/.version: increased version number to 2.5.5
2351 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2352 linking is done manually in pic16 port's _linkEdit,
2353 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2354 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2355 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2356 allocate asmop as AOP_ACC,
2357 (aopForRemat): added parameter 'bool result' in function declaration,
2358 (pic16_aopGet): return AOP_ACC when accessing WREG,
2359 (pic16_popGetTempReg): minor modification,

2370 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2371 call to allocReg, not by manually allocating a new one,
2372 (pic16_assignRegisters): now before going through the register
2373 allocating functions mark all registers as free. This eliminates some
2374 side effects resulting from peephole parser done earlier in the backbone
2376 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2434 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2435 which dumps before the function entry point a data byte which represents
2436 the number of the local variables used by the specified function, added
2437 'xinst' for initial support for Extended Instruction Support,
2438 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2439 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2440 port->fun_prefix anymore (may change later),
2441 (genFunction, genEndFunction): do not store/restore local registers for
2442 _main (this should take care the --main-return command line option in
2444 (genOr): removed some legacy pic-port instructions,
2445 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2446 performing operations with SFR's causes data to be written more than
2447 once to each SFR. Perhaps SFRs should be handled in special cases...
2448 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2450 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2451 into account for stack starting position,

2453 --extended or -y for Extended Instruction Support,
2454 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2455 (deassignLRs): *** perhaps the most important change, old 'for' code
2456 (commented out for reference), didn't account for some registers which
2457 were left marked 'not free' after a pointer operation. The change
2458 reduces register usage a lot in some cases

4705 * device/lib/pic16/libc/delay/: NEW, c sources for the delay functions,
4706 * device/lib/pic16/libc/utils/: minor modifications in the .S sources,
4707 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
4708 _do_cinit function, because the previous failed when local variables
4709 where not placed in the same memory bank,
4710 * device/lib/pic16/libsdcc/char/: various modifications to improve
4711 library performance,
4712 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
4713 information on the new functions of the c library and more...
4715 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4722 if condition == CARRY)
4723 * (genCmp): adapted to new genSkipc semantics
4724 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
4725 on rIfx (genCmp was broken)
4727 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4729 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4730 * src/z80/main.c (_keywords[]),
4731 * src/SDCCglobal.h (struct options),
4733 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4734 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4735 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4736 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4737 always available in leading double underscore form. The C99 support is
4738 mostly missing, but it's a start.
4739 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4740 reserved identifier "__data".
4742 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4744 * src/mcs51/peeph.def: fixed bug 1170013

4786 immedDom() returning wrong block; probably fixes bug #1160833)
4788 2005-03-20 Borut Razem <borut.razem AT siol.net>
4790 * support/scripts/inc2h.pl: WIN32 port

4794 * device/lib/makefile.in: added abs.c and labs.c
4796 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4798 * device/include/stdint.h: added
4799 * device/lib/abs.c: added
4800 * device/lib/labs.c: added
4801 * device/include/stdlib.h: added abs() and labs() prototypes

4818 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4820 * device/lib/printf_large.c: removed inline assembly for portability and
4821 readability. Use printf_fast if speed or size are more important.
4822 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4823 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4825 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4827 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4828 prevent compiler warning
4830 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4832 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4833 moved to level 0 and declared as static. Also they are explicit
4834 placed in access bank. This was necessery because some times they
4835 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4836 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4837 optimizations. Currently only compare to unsigned char is implemented,
4838 * src/pic16/gen.c: added fReturnIdx array,
4839 * (struct resolvedIfx) is moved to gen.h and made public,
4840 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4841 * (aopForSym): added an optimization to directly store in stack of
4842 the operand of a SEND iCode,
4843 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4844 but as registers instead (AOP_REG) using the fReturnIdx array,
4845 * (pic16_freeAsmop): remove the freed register from the
4846 _G.sregsAlloc field,
4847 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4848 a compare of 'WREG',
4849 * (pic16_popGetTempRegCond): changed function prototype, now
4850 function takes also a bitVector argument v which holds the current
4851 set of registers that are allocated for stack access by aopForSym,
4852 registers allocated in aopForSym for accessing stack symbols are not
4853 any more part of the functions usedRegs field,
4854 * (genCall): some times aopOp is called for a stack variable to be
4855 send, aopForSym might perform the push, if this is true make sure
4856 that genCall doesn't push the variable twice by testing _G.resDirect,
4857 * (genFunction): changed testing for unspecified interrupt number
4858 from 256 to INTNO_UNSPEC,
4859 * modified selection scheme of frame pointer generation. Previously
4860 if function did use local registers a frame pointer was generated,
4861 now a frame pointer is generated only if function has arguments
4862 (that need PLUSW2 register access), or has stack arguments, or the
4863 compiler is not instructed to omit the frame pointer,
4864 * (genEndFunction): before restoring local registers that were saved
4865 in the function preamble, also restore the registers that *might*
4866 have been allocated for stack access,
4867 * (genRet): removed some old comments,
4868 * (genCmp, the active (RN's) version): added a call to the
4869 pic16_genCmp_special function to perform the compare with a more
4870 robust and optimized way,
4871 * (genInline): a feature has been added in inline code generation,
4872 which allows a wildcard variable substitution when writing inline
4873 assembly. Code is incomplete and experimental therefore undocumented,
4874 * (genCast): changed order of aopOp for result and right to allow
4875 aopForSym to directly load the result if possible,
4876 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4877 perform an optimized compare on some selected special occasions,
4878 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4879 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4880 generate an IVT any more,
4881 * src/pic16/main.c (pic16_optionsTable): added command line option
4883 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4884 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4886 * src/pic16/NOTES: Raphael Neider added in list of active developers
4887 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4888 jumptable_end to prevent bug #,
4889 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4890 inCond and outCond fields,
4891 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4892 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4893 turn off register spilling,
4894 * (packRegsForOneUse): synced with other ports' versions although it
4895 is not used currently,
4896 * (pic16_packRegisters): added an optimization while reading
4897 structure bitfields, some registers may be saved (malloc code is
4898 decreased by 80 bytes)
4900 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4902 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4903 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4904 this can be optimized more?
4906 2005-03-10 Raphael Neider <rneider AT web.de>
4908 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4909 genNearPointerGet): (hopefully) fixed access to bitfields via
4910 pointers (p->bitN = x; and x = p->bitN; failed)
4912 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5099 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5100 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5101 this might fix SIGSEGVs on MinGW...
5102 * src/SDCCopt.c (killDeadCode): restored original behaviour
5103 (volatile operands might get thrown away though)
5105 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5585 be extensively tested in the future. Standard disclaimer here.
5586 Library is not automatically build yet. But one can build it by
5587 invoking 'make' inside the libc directory.

5602 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5604 * (genCast): began a fix to optimize the casting of a bit to another
5605 bit, now assigning a bitfield to another bitfield will fail, sorry,

8628 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8630 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8631 loaded with the linker search paths (-L arguments) and the libraries
8632 to be linked with the current source (-l arguments). Changes
8633 currently will affect only the pic16 port.
8634 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8635 include path the port specific paths and port specific libraries,
8636 * gplink command now contains the $3 argument,
8637 * src/pic16/device.h,
8638 * src/pic16/device.c,: structure PIC_device is made public and
8639 renamed to PIC16_device, the same for variable Pics which is renamed

8654 Documenting changes from previous commits.
8655 * configure.in (version 1.56),
8656 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8657 when generating output files to configure the pic16 library,
8658 but now I've commented it out, since gputils aren't installed in the
8659 SF compile farm, so library won't compile
8661 * device/lib/Makefile.in (version 1.56): initially I've added in
8662 target 'all' the prerequestive 'model-pic16' so it compiled the
8663 pic16 library, but now I've commented it out for the same reasons
8665 * added targets 'model-pic16' and 'objects-pic16' to compile the
8667 * added target 'port-specific-objects-pic16' to handle the
8668 generated libraries and copy them into the build/ directory
8669 * added target 'clean-intermediate-pic16' to clean intermediate
8670 files into pic16 directory
8671 * in target 'installdirs' added line to create directory pic16 in
8672 the installation path
8674 * device/include/Makefile.in (version 1.11): in target 'install'
8675 added lines to copy all header files to installation path,
8676 * in target 'installdirs' added line create directory for pic16
8677 headers in the installation path

8692 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8693 option so that it actually works. Made it specific to the z80, since
8694 the gbz80 doesn't have these kinds of I/O ports.
8696 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8698 * device/include/z180.h,

8722 via literal number. The symbol is placed in the corresponding
8723 position of the data ram
8724 * (pic16_dump_section): relocatable and absolute uninitialized
8725 data are now emitted in sorted order to reduce section naming,
8726 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8727 weren't marked as being in the access bank,
8729 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8731 Added portion of GNU PIC Library under the directory
8732 device/include/pic16 and device/lib/pic16. These files
8733 contain the declarations of SFRs for the PIC18Fxx2 devices.
8734 The directory is initialized via configure from toplevel.
8736 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8738 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8739 the spilllocations to be compared correctly
8741 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8743 * src/SDCCast.c (decorateType): fixed bug introduced today

8763 * doc/sdccman.lyx: Moved and added some sections, small changes
8764 all over. Telling LaTeX to be less strict with word spacing
8765 to better keep the right margin. Changed some notes about
8766 maintainance of the ports in section 3.2.1 - is it OK like this?
8768 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8806 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8808 * src/pic16/peeph.def: all peepholes with movff are commented out,
8809 because there is a problem in the pcode peep optimizer,
8810 * src/pic16/ralloc.c: the register allocator can now reuse local
8811 function symbols for another function. This saves register usage.
8812 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8814 Added file src/pic16/NOTES with information about program writing on
8815 the current port version.

8844 gen51Code): more efficient parameter receive for --model-large
8847 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8850 * src/z80/main.c: added missed needLinkerScript flags (more than
8851 one port structure defined in these file)
8852 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8868 needLinkerScript flag
8870 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8871 * src/pic/glue.c: added variable udata_section_name to
8872 override default uninitialized data segment definition for
8873 devices only with SHAREBANK memory (reported from Erik Epetrich)
8874 * (pic14emitOverlay): modified to emit a commented overlay segment
8875 directive when no overlay data exist
8876 * (picglue): modified to emit uninitialized data segment
8877 according to udata_section_name

8883 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8884 object file from '.rel' to '.o' in port->linker structure,

8887 2004-01-07 Borut Razem <borut.razem AT siol.net>
8889 * support/scripts/sdcc.nsi: update PATH
8890 * support/scripts/sdcc.ico: craeted

8897 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8899 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8901 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8903 include information about variables allocated to the overlay
8906 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8908 * as/mcs51/lkmain.c: Help about -Y option

8920 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8922 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8923 (default behaviour).
8925 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8927 A python script to validate compiler diagnostic messages. It can be
8928 used to verify that sdcc complains about bad c source code and
8929 gives a good location of the error.
8930 * support/valdiag/Makefile,
8931 * support/valdiag/valdiag.py,
8932 * support/valdiag/tests/*
8934 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8936 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8947 * src/common.h: added ifndef/define/endif macros
8948 around the header file.
8949 Bug reported from Jesus Calvino-Fraga
8951 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8953 * sdcc.spec: updated
8954 * device/include/Makefile.in: don't install CVS directories
8955 * device/lib/Makefile.in: added removal of CVS directories after install
8956 * doc/Makefile: fixed install, added local_icons
8957 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8958 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8959 * src/ds390/gen.c (genRightShift): fixed bug #870788
8960 * src/SDCCast.c (decorateType): fixed bug #870781
8962 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8964 PIC16 port related changes:
8965 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8966 added variable stackPos,
8968 * gen.c: genCall, assignResultValue: added support for
8969 pushing/retrieving function parameters to/from stack,
8970 genFunction,genEndFunction: setup stack frame for the
8972 genAddrOf: will be changed according to bug 863624
8974 * added files genutils.c and genutils.h which contain gen*
8975 debugged and optimised functions extracted from gen.c
8977 * glue.c: added variable 'externs' which holds extern symbols,
8978 pic16emitRegularMap: is modified to properly handle relocatable
8979 symbols under the new scheme,
8980 pic16createInterruptVect: is modified
8981 pic16printPublics: is modified to emit 'global' assembler directives,
8982 added pic16_printExterns to print extern symbols,
8983 pic16glue: initializes stack/frame pointer in the beginning of
8984 the assembly output. Temporary hack, will be corrected later,
8985 because gplink yet does not support stack and SDCC does not
8986 yet support a type of crt0.o object to create the final binary.
8988 * Removed many lines that contain 8051 legacy code.
8989 * The code is finally placed under a 'code' directive.
8990 * Added port specific options.
8992 * _process_pragma: simplified since now we do not need *special*
8993 include file to define SFR registers. But a separate header
8994 will be needed. This will be developed later.
8995 * _pic16_parseOptions: added, parses port specific options:
8996 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8997 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8998 --preplace-udata-with=
9000 * _pic16_setDefaultOptions: modified to initialize section names,
9001 but hack is temporarly out of order since it needs improvement.
9002 * _pic16_genAssemblerPreamble: configuration words are emitted by
9003 their address instead of their name. This part is incomplete and
9004 supports only the 18Fxx2 devices. Other devices will emit an error
9005 during assembly since they do not contain the same set of config
9007 * _pic16_genIVT: is modified,
9009 * pcode.c: added definitions for some hardware registers that are needed
9011 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9012 All PCI entries are updated. Now LFSR is supported.
9013 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9014 * added pic16_newpCodeOpLit2 to support instructions with
9015 two literal arguments
9016 * pic16_pCode2str: corrected code that emits assembler instructions
9017 with two literal operands and those that have an access bit modifier
9018 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9019 this fixes a bug which caused some labels to be lost, when an
9020 assembler directive was added, i.e. banksel,
9021 * pic16_FixRegisterBanking: improved logic that causes the insertion
9023 * InlineFunction: functions that are called once, are not any more
9024 inlined. This can be a port option in the future,
9026 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9028 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9029 hold the corresponding uninitialized symbols,
9030 * pic16_allocProcessorRegister: registers have explicit marked the
9032 * pic16_allocInternalRegister: registers are explicit marked as
9034 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9035 processing list, so bit registers were lost,
9038 * ralloc.h: added field 'accessBank' and original symbol operand
9039 in register definition,
9040 * removed the field isMapped from register definition,
9042 ** Several functions have been removed from various sources:
9043 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9044 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9045 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9046 pic16_assignRelocatableRegisters
9048 ** others have been introduced:
9049 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9050 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9052 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9054 * support/scripts/inc2h.pl: changed definition of BIT_AT
9055 to emit 'sbit at' instead of 'bit at'. This was a request.
9057 PIC16 port related preliminary changes:
9058 * gen.c: prefixed function popRegFromString with
9059 pic16_ and all references to it corrected
9060 * pcode.c: all pic16_pc_* hardware registers prefixed
9061 with underscore (_),
9062 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9063 * ralloc.c: newReg(): when register is REG_SFR then
9064 set address to rIdx,
9065 pic16_allocProcessorRegister(): marks register wasUsed=0
9066 pic16_writeUsedRegs(): added a call to assign processor
9067 registers via pic16_assignFixedRegisters
9069 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9071 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9072 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9073 variables in unused register banks. Also the SSEG is placed
9074 wherever there is enough space for it, and IDATA can be anywhere
9075 in internal RAM. For now compile using -Wl-Y[stack_size].
9076 The mem file is different for this option as well, since it
9077 makes no sense of talking about DSEG lenght.
9079 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9081 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9082 in certain cases, e.g. when ROM assignment, patch provided
9083 from Albert den Haan.
9085 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9328 it breaks with bitfields, extern declarations, and gcse analysis.
9329 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9330 could be assigned through a pointer, so don't complain.

10108 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10109 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10110 type for bits was changed. It resulted in bit variables becoming
10111 global, which is not permitted in PIC 14 assembly output.
10113 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10128 A few small changes that speed up the peephole optimizer.
10132 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10134 Try to make the peephole optimizer smarter by maintaining
10135 an association between the assembly source code and the
10136 iCodes that originated them. Put this information to use
10137 with a new peephole rule condition "notVolatile" so that
10138 the rules can be aggressive yet still safe.
10143 * src/mcs51/peeph.def
10145 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10149 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10150 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10151 if the left or right operand symbols have the accuse flag set.
10153 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10155 Changed the type of the result of the ! (NOT) operator to char;
10156 previously it returned the same type as the source. This allows
10157 us to eliminate all the genFloatNot functions (all of its target
10158 implementations were very buggy) since !float can use the same
10161 * src/SDCCicode.c (ast2iCode): ! returns char

10172 during interrupts. Ensure WSAVE is located at a shared bank address.
10173 2. Fixed page selection in some places
10174 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10175 the registers name strings.
10176 4. Fixed "signed / unsigned compare" compiler warnings.
10177 5. The PIC port manages its own allocation of the general purpose
10178 registers, but makes no attempt to reuse them. As a result when
10179 compiling it soon runs out of general purpose registers. Some
10180 additional code was added to the files pcode.c and device.c to walk
10181 through the function call tree and rename the registers so that they
10191 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10192 genPlus() & genMinus() when the result is the same as left or right

10198 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10200 Made bitfield a distinct type from bit so that bitfields
10201 convert as per ANSI C and bits retain their traditional
10202 boolean style behaviour. Implemented bitfield support in
10210 * src/ds390/gen.c: bit v bitfield split
10211 * src/z80/gen.c: New support for bitfields
10212 * support/regression/tests/bitfields.c: reenabled z80,
10215 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10217 Rules 246.x, 247.x relate to bitfields, the others speed up
10218 access to xdata mapped I/O devices.
10220 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10222 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10224 Cleaned up genPackBits and genUnpackBits and added two helper
10225 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10226 for literal assignments in genPackBits (thanks to Frieder for
10232 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10234 Fixed bug #748310 (pointer to function type mishandled when the
10235 function name is omitted). Also fixed a SIGSEGV when a function
10236 attribute (reentrant, etc) is used on a non-function or on a
10237 function but misplaced before the parameter list.
10239 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

10264 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10266 Made the constant following the "interrupt" keyword optional. If
10267 omitted, the function will not automatically be given an entry
10268 in the interrupt vector table (similar to #pragma NOIV, but
10269 less syntacticly kludgy). The interrupt number is also now
10270 range checked. Also fixed a bug in the high order bit example

10746 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10747 the regression tests I'm not brave enough to enable 245.b, 245.c
10748 * doc/sdccman.lyx: added latex preamble for hyperref package.
10749 Using pdflatex this will give you a hyperlinked pdf file with

10790 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10791 it can be defined with CFLAGS when running configure
10792 * src/SDCCmain.c: fixed compiling + linking with object files
10794 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10799 * src/SDCCmain.c: linkOptions is changed to set *,
10800 added if/endif conditional macros to remove options help
10801 messages from optionsTable when a port is not configured, added
10802 support for the PIc16 port in the ports table, when executing
10803 the compiler with no port specified on command line, a default
10804 port is selected with the new macro DEFAULT_PORT which is
10805 defined in port.h, in setDefaultOptions() linkOptions is removed
10806 from initialization assignment, since now it is a set,
10807 parseCmdLine uses setParseWithComma for linkOptions, in
10808 linkEdit() linkOptions are accessed with new function indexSet()
10809 which returns the i'th item of a set variable. See SDCCset.c, in
10810 linkEdit() when calling buildCmdLine(), added linkOptions as
10811 last argument. Now users can pass arguments to gplink via the
10812 -Wl option, main() uses pic16glue() to glue up pic16 programs
10813 * src/SDCCpeeph.c: various changes to support pic16
10814 * src/SDCCset.c: added function void *indexSet(set *, int) to

10824 * src/pic16/glue.c: commented out some error producing lines
10825 * src/pic16/main.c: __config directives are commented out to stop
10826 gpasm complaining and test the linkage with gplink, _linkCmd and
10827 _asmCmd changed to be more gplink and gpasm friendly
10828 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10829 produced an error when parsed, peep rule 12 is added to utilize
10830 movff, but it is commented out since the pCode does not support
10831 yet a command with 2 address arguments
10833 2003-05-18 <johan AT balder>
10835 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11896 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11899 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11900 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11901 following files to include the previous two files: aslink.dsp,
11902 Makefile.aslink, Makefile.bcc, and Makefile.in.
11904 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11905 .adb instead of .cdb
11907 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11909 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11910 value from option --iram-size.
11912 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11914 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11917 2002-09-18 <wiml AT hhhh.org>
11919 * SDCClrange.h: exposed setFromRange() and setToRange()
11920 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11921 packRegsForAccUse() (bug 542397)
11922 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11923 multiple times and emitting the fetch operations more than once
11924 added aopGetUsesAcc() function to allow binary operators to
11925 fetch their operands in the correct order; made genMinus() emit
11926 compact code for X = LITERAL - Y
11928 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11929 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11930 sprintf() in line 1267.
11932 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11933 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11936 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11937 Changes to aslink (All the changes are marked with 'JCF'):
11939 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11942 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11943 area BSEG. Also moves, if possible, the DATA area down into the internal
11944 ram so more space is available.
11946 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11949 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11950 not bytes. Function summary() which creates a memory usage summary
11951 file with extension .mem. Reports of overlaping stack and small stack
11952 size. If the space for the stack is less than 16 bytes aslink trows a
11955 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11956 the 8051. Option 'y' for memory summary output file.
11958 Changes to sdcc (All the changes are marked with 'JCF'):
11960 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11962 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11963 overlaying area for it (uses RegBankUsed[4]).
11965 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11966 bank zero as used by default. By default aslink locates the stack
11967 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11968 the creation of the .mem file. Delegates the allocation of data area
11969 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11970 the begining of the stack area to aslink.
11972 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11973 glue() in SDCCglue.c creates an area for it.
11975 2002-09-03 Borut Razem <borut.razem AT siol.net>
11976 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11977 sdcc/src/pic/glue.c:
11978 introduced atexit() handler for teporay files removal in case of
11979 errors, assertions, ...
11981 2002-08-29 Borut Razem <borut.razem AT siol.net>
11982 * sdcc/support/cpp2/auto-host_vc_in.h:
11983 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11984 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11985 Maybe there is a similar problem with BORLANDC? It should be checked!
11987 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11988 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11989 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11990 was not executed, and the compiler (cl) launched a warning:
11991 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11993 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11999 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12000 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12001 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12002 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12003 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12004 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12005 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12006 - added Release configuration in VS projects
12007 - review of compiler an linker options
12008 - VC .exe files are generated in bin_vc directory, not to interfere
12009 with binaries generated from other projects (cygwin, mingw, bcc ...)
12011 * sdcc/src/yacc.dsp: added
12013 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12014 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12015 and insert the version number definitions from .version
12017 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12019 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

12026 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12028 2002-08-11 Borut Razem <borut.razem AT siol.net>
12029 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12031 2002-08-10 Borut Razem <borut.razem AT siol.net>
12032 * src/SDCCmain.c (main):
12033 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12034 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12035 The consequence was that some temporary files were not removed.
12038 unification of code in functions tempfilename() and tempfile():
12039 function tempnam() is defined in Visual Studio 6.0 and .NET
12041 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12043 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12044 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12045 - removed compiler command line option /WX: Treats all warnings as errors
12046 - update a list of source files, included into the project
12048 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12049 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12050 changed project type to Generic Project so that can be correcly converted to VS.NET project
12052 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12054 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12056 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12058 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12059 added return 0 statements after assert() to make compiler happy
12061 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12062 added newline in the def file to keep MSC compiler satisfied
12064 * sdcc/src/z80/gen.c:
12065 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12066 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12067 - solved MSC error in function aopDump()
12069 * sdcc_vc.h: define PREFIX as "\\sdcc"
12071 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12244 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12246 * sdcc/src/SDCCloop.c:
12247 Previous fix was not good. basic blocks that have "break" or "return" are
12248 not really partof a loop , but live ranges used in these blocks should
12249 be live thru the entire loop, so set partOfLoop but don't add them to
12252 2002-02-21 <johan AT FRIJA>
12254 * src/SDCCcse.c: fixed bug #514308
12256 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
