2000 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2002 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2003 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2005 One basic decision: e.g. src/clean.mk includes further files. In order
2006 to make this work there are two solutions:
2007 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2008 run configure on them. This way they can use
2009 'include $(srcdir)/port-clean.mk'
2010 - always include clean.mk by the Makefile at the same level. To avoid
2011 that `make clean` tries to include and build Makefile.dep the
2012 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2013 implemented, because now even `make uninstall` doesn't create
2014 Makefile.in. clean.mk could be eliminated by pasting it in
2017 * debugger/mcs51/Makefile.in: build own objects from library sources
2018 (SLIB, SDCC) in current directory
2020 * configure, configure.in: renamed --disable-device-lib-build in
2021 --disable-device-lib; added --enable-doc, the required tools are
2022 searched by configure; added result message; the toolchain for the
2023 belonging ports are now only built, if the port is enabled.
2025 * support/regression/*: all output is written in directory gen, because
2026 the fwk and ports directories don't livet in the build tree using vpath
2028 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2029 --disable-device-lib, added --enable-doc, added section VPATH
2031 * sim/ucsim/configure.in,
2032 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2033 z80 are enabled by default
2035 2006-04-24 Raphael Neider <rneider AT web.de>
2037 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2038 to config word, "pic14_"-prefixed some extern functions
2039 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2040 config word has been found
2041 * src/pic/device.h: added prototypes
2042 * src/pic/pcode.c: added "pic14_"-prefix where needed
2043 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2045 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2048 (pic14createInterruptVect): moved generating __config directives away

2058 registers that have not been assigned proper liveranges,
2059 fixes #1469504 and #1474602,
2060 (pCodeRegOptimizeRegUsage): fixed typo in comment

2064 * device/examples/main8051.c: deleted - it was removed from CVS

2306 implemented patch 1120823 Thanks to Willy De la Court (normal
2307 interrupts need an interrupt number now if they are made critical),
2308 and enabled nesting of critical functions though not for gbz80
2309 (genCritical, genEndCritical): added functions
2310 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2311 * src/z80/mappings.i: added "ei" to all mappings

2323 the left operand is shorter than the result (c* = lit-c* + int),
2325 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2328 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2330 * src/.version: increased version number to 2.5.5
2331 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2332 linking is done manually in pic16 port's _linkEdit,
2333 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2334 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2335 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2336 allocate asmop as AOP_ACC,
2337 (aopForRemat): added parameter 'bool result' in function declaration,
2338 (pic16_aopGet): return AOP_ACC when accessing WREG,
2339 (pic16_popGetTempReg): minor modification,

2350 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2351 call to allocReg, not by manually allocating a new one,
2352 (pic16_assignRegisters): now before going through the register
2353 allocating functions mark all registers as free. This eliminates some
2354 side effects resulting from peephole parser done earlier in the backbone
2356 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2406 2006-03-06 Borut Razem <borut.razem AT siol.net>
2408 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2409 made the linker quiet

2414 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2415 which dumps before the function entry point a data byte which represents
2416 the number of the local variables used by the specified function, added
2417 'xinst' for initial support for Extended Instruction Support,
2418 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2419 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2420 port->fun_prefix anymore (may change later),
2421 (genFunction, genEndFunction): do not store/restore local registers for
2422 _main (this should take care the --main-return command line option in
2424 (genOr): removed some legacy pic-port instructions,
2425 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2426 performing operations with SFR's causes data to be written more than
2427 once to each SFR. Perhaps SFRs should be handled in special cases...
2428 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2430 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2431 into account for stack starting position,

2433 --extended or -y for Extended Instruction Support,
2434 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2435 (deassignLRs): *** perhaps the most important change, old 'for' code
2436 (commented out for reference), didn't account for some registers which
2437 were left marked 'not free' after a pointer operation. The change
2438 reduces register usage a lot in some cases

4699 2005-03-26 Raphael Neider <rneider AT web.de>
4701 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
4702 if condition == CARRY)
4703 * (genCmp): adapted to new genSkipc semantics
4704 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
4705 on rIfx (genCmp was broken)
4707 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4709 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4710 * src/z80/main.c (_keywords[]),
4711 * src/SDCCglobal.h (struct options),
4713 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4714 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4715 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4716 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4717 always available in leading double underscore form. The C99 support is
4718 mostly missing, but it's a start.
4719 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4720 reserved identifier "__data".
4722 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4724 * src/mcs51/peeph.def: fixed bug 1170013

4732 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
4735 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4737 * src/port.h (struct PORT),
4738 * src/avr/ralloc.c (avr_assignRegisters),
4740 * src/ds390/ralloc.c (ds390_assignRegisters),
4742 * src/hc08/ralloc.c (hc08_assignRegisters),

4764 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4765 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4766 immedDom() returning wrong block; probably fixes bug #1160833)
4768 2005-03-20 Borut Razem <borut.razem AT siol.net>
4770 * support/scripts/inc2h.pl: WIN32 port
4772 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4774 * device/lib/makefile.in: added abs.c and labs.c
4776 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4778 * device/include/stdint.h: added
4779 * device/lib/abs.c: added
4780 * device/lib/labs.c: added
4781 * device/include/stdlib.h: added abs() and labs() prototypes
4782 * device/lib/libsdcc.lib: added abs and labs
4783 * device/include/float.h,

4796 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4798 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4800 * device/lib/printf_large.c: removed inline assembly for portability and
4801 readability. Use printf_fast if speed or size are more important.
4802 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4803 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4805 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4807 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4808 prevent compiler warning
4810 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4812 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4813 moved to level 0 and declared as static. Also they are explicit
4814 placed in access bank. This was necessery because some times they
4815 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4816 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4817 optimizations. Currently only compare to unsigned char is implemented,
4818 * src/pic16/gen.c: added fReturnIdx array,
4819 * (struct resolvedIfx) is moved to gen.h and made public,
4820 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4821 * (aopForSym): added an optimization to directly store in stack of
4822 the operand of a SEND iCode,
4823 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4824 but as registers instead (AOP_REG) using the fReturnIdx array,
4825 * (pic16_freeAsmop): remove the freed register from the
4826 _G.sregsAlloc field,
4827 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4828 a compare of 'WREG',
4829 * (pic16_popGetTempRegCond): changed function prototype, now
4830 function takes also a bitVector argument v which holds the current
4831 set of registers that are allocated for stack access by aopForSym,
4832 registers allocated in aopForSym for accessing stack symbols are not
4833 any more part of the functions usedRegs field,
4834 * (genCall): some times aopOp is called for a stack variable to be
4835 send, aopForSym might perform the push, if this is true make sure
4836 that genCall doesn't push the variable twice by testing _G.resDirect,
4837 * (genFunction): changed testing for unspecified interrupt number
4838 from 256 to INTNO_UNSPEC,
4839 * modified selection scheme of frame pointer generation. Previously
4840 if function did use local registers a frame pointer was generated,
4841 now a frame pointer is generated only if function has arguments
4842 (that need PLUSW2 register access), or has stack arguments, or the
4843 compiler is not instructed to omit the frame pointer,
4844 * (genEndFunction): before restoring local registers that were saved
4845 in the function preamble, also restore the registers that *might*
4846 have been allocated for stack access,
4847 * (genRet): removed some old comments,
4848 * (genCmp, the active (RN's) version): added a call to the
4849 pic16_genCmp_special function to perform the compare with a more
4850 robust and optimized way,
4851 * (genInline): a feature has been added in inline code generation,
4852 which allows a wildcard variable substitution when writing inline
4853 assembly. Code is incomplete and experimental therefore undocumented,
4854 * (genCast): changed order of aopOp for result and right to allow
4855 aopForSym to directly load the result if possible,
4856 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4857 perform an optimized compare on some selected special occasions,
4858 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4859 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4860 generate an IVT any more,
4861 * src/pic16/main.c (pic16_optionsTable): added command line option
4863 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4864 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4866 * src/pic16/NOTES: Raphael Neider added in list of active developers
4867 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4868 jumptable_end to prevent bug #,
4869 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4870 inCond and outCond fields,
4871 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4872 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4873 turn off register spilling,
4874 * (packRegsForOneUse): synced with other ports' versions although it
4875 is not used currently,
4876 * (pic16_packRegisters): added an optimization while reading
4877 structure bitfields, some registers may be saved (malloc code is
4878 decreased by 80 bytes)
4880 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4882 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4883 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4884 this can be optimized more?
4886 2005-03-10 Raphael Neider <rneider AT web.de>
4888 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4889 genNearPointerGet): (hopefully) fixed access to bitfields via
4890 pointers (p->bitN = x; and x = p->bitN; failed)
4892 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5079 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5080 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5081 this might fix SIGSEGVs on MinGW...
5082 * src/SDCCopt.c (killDeadCode): restored original behaviour
5083 (volatile operands might get thrown away though)
5085 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5525 generated for switch statements. For now you need to set the
5526 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5527 Now 4 algorithms for mcs51 jumptable generation are used:
5528 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

8608 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8610 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8611 loaded with the linker search paths (-L arguments) and the libraries
8612 to be linked with the current source (-l arguments). Changes
8613 currently will affect only the pic16 port.
8614 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8615 include path the port specific paths and port specific libraries,
8616 * gplink command now contains the $3 argument,
8617 * src/pic16/device.h,
8618 * src/pic16/device.c,: structure PIC_device is made public and
8619 renamed to PIC16_device, the same for variable Pics which is renamed

8632 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8634 Documenting changes from previous commits.
8635 * configure.in (version 1.56),
8636 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8637 when generating output files to configure the pic16 library,
8638 but now I've commented it out, since gputils aren't installed in the
8639 SF compile farm, so library won't compile
8641 * device/lib/Makefile.in (version 1.56): initially I've added in
8642 target 'all' the prerequestive 'model-pic16' so it compiled the
8643 pic16 library, but now I've commented it out for the same reasons
8645 * added targets 'model-pic16' and 'objects-pic16' to compile the
8647 * added target 'port-specific-objects-pic16' to handle the
8648 generated libraries and copy them into the build/ directory
8649 * added target 'clean-intermediate-pic16' to clean intermediate
8650 files into pic16 directory
8651 * in target 'installdirs' added line to create directory pic16 in
8652 the installation path
8654 * device/include/Makefile.in (version 1.11): in target 'install'
8655 added lines to copy all header files to installation path,
8656 * in target 'installdirs' added line create directory for pic16
8657 headers in the installation path

8672 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8673 option so that it actually works. Made it specific to the z80, since
8674 the gbz80 doesn't have these kinds of I/O ports.
8676 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8702 via literal number. The symbol is placed in the corresponding
8703 position of the data ram
8704 * (pic16_dump_section): relocatable and absolute uninitialized
8705 data are now emitted in sorted order to reduce section naming,
8706 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8707 weren't marked as being in the access bank,
8709 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

8744 all over. Telling LaTeX to be less strict with word spacing
8745 to better keep the right margin. Changed some notes about
8746 maintainance of the ports in section 3.2.1 - is it OK like this?
8748 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8788 * src/pic16/peeph.def: all peepholes with movff are commented out,
8789 because there is a problem in the pcode peep optimizer,
8790 * src/pic16/ralloc.c: the register allocator can now reuse local

8854 * (pic14emitOverlay): modified to emit a commented overlay segment
8855 directive when no overlay data exist
8856 * (picglue): modified to emit uninitialized data segment
8857 according to udata_section_name

8862 arguments via -W option
8863 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8864 object file from '.rel' to '.o' in port->linker structure,

8867 2004-01-07 Borut Razem <borut.razem AT siol.net>
8869 * support/scripts/sdcc.nsi: update PATH
8870 * support/scripts/sdcc.ico: craeted

8883 include information about variables allocated to the overlay
8886 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8888 * as/mcs51/lkmain.c: Help about -Y option

8900 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8902 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8903 (default behaviour).
8905 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8907 A python script to validate compiler diagnostic messages. It can be
8908 used to verify that sdcc complains about bad c source code and
8909 gives a good location of the error.
8910 * support/valdiag/Makefile,
8911 * support/valdiag/valdiag.py,
8912 * support/valdiag/tests/*
8914 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8927 * src/common.h: added ifndef/define/endif macros
8928 around the header file.
8929 Bug reported from Jesus Calvino-Fraga
8931 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8933 * sdcc.spec: updated
8934 * device/include/Makefile.in: don't install CVS directories
8935 * device/lib/Makefile.in: added removal of CVS directories after install
8936 * doc/Makefile: fixed install, added local_icons
8937 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8938 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8939 * src/ds390/gen.c (genRightShift): fixed bug #870788
8940 * src/SDCCast.c (decorateType): fixed bug #870781
8942 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8944 PIC16 port related changes:
8945 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8946 added variable stackPos,
8948 * gen.c: genCall, assignResultValue: added support for
8949 pushing/retrieving function parameters to/from stack,
8950 genFunction,genEndFunction: setup stack frame for the
8952 genAddrOf: will be changed according to bug 863624
8954 * added files genutils.c and genutils.h which contain gen*
8955 debugged and optimised functions extracted from gen.c
8957 * glue.c: added variable 'externs' which holds extern symbols,
8958 pic16emitRegularMap: is modified to properly handle relocatable
8959 symbols under the new scheme,
8960 pic16createInterruptVect: is modified
8961 pic16printPublics: is modified to emit 'global' assembler directives,
8962 added pic16_printExterns to print extern symbols,
8963 pic16glue: initializes stack/frame pointer in the beginning of
8964 the assembly output. Temporary hack, will be corrected later,
8965 because gplink yet does not support stack and SDCC does not
8966 yet support a type of crt0.o object to create the final binary.
8968 * Removed many lines that contain 8051 legacy code.
8969 * The code is finally placed under a 'code' directive.
8970 * Added port specific options.
8972 * _process_pragma: simplified since now we do not need *special*
8973 include file to define SFR registers. But a separate header
8974 will be needed. This will be developed later.
8975 * _pic16_parseOptions: added, parses port specific options:
8976 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8977 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8978 --preplace-udata-with=
8980 * _pic16_setDefaultOptions: modified to initialize section names,
8981 but hack is temporarly out of order since it needs improvement.
8982 * _pic16_genAssemblerPreamble: configuration words are emitted by
8983 their address instead of their name. This part is incomplete and
8984 supports only the 18Fxx2 devices. Other devices will emit an error
8985 during assembly since they do not contain the same set of config
8987 * _pic16_genIVT: is modified,
8989 * pcode.c: added definitions for some hardware registers that are needed
8991 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8992 All PCI entries are updated. Now LFSR is supported.
8993 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8994 * added pic16_newpCodeOpLit2 to support instructions with
8995 two literal arguments
8996 * pic16_pCode2str: corrected code that emits assembler instructions
8997 with two literal operands and those that have an access bit modifier
8998 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8999 this fixes a bug which caused some labels to be lost, when an
9000 assembler directive was added, i.e. banksel,
9001 * pic16_FixRegisterBanking: improved logic that causes the insertion
9003 * InlineFunction: functions that are called once, are not any more
9004 inlined. This can be a port option in the future,
9006 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9008 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9009 hold the corresponding uninitialized symbols,
9010 * pic16_allocProcessorRegister: registers have explicit marked the
9012 * pic16_allocInternalRegister: registers are explicit marked as
9014 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9015 processing list, so bit registers were lost,
9018 * ralloc.h: added field 'accessBank' and original symbol operand
9019 in register definition,
9020 * removed the field isMapped from register definition,
9022 ** Several functions have been removed from various sources:
9023 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9024 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9025 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9026 pic16_assignRelocatableRegisters
9028 ** others have been introduced:
9029 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9030 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9032 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9034 * support/scripts/inc2h.pl: changed definition of BIT_AT
9035 to emit 'sbit at' instead of 'bit at'. This was a request.
9037 PIC16 port related preliminary changes:
9038 * gen.c: prefixed function popRegFromString with
9039 pic16_ and all references to it corrected
9040 * pcode.c: all pic16_pc_* hardware registers prefixed
9041 with underscore (_),
9042 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9043 * ralloc.c: newReg(): when register is REG_SFR then
9044 set address to rIdx,
9045 pic16_allocProcessorRegister(): marks register wasUsed=0
9046 pic16_writeUsedRegs(): added a call to assign processor
9047 registers via pic16_assignFixedRegisters
9049 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9051 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9052 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9053 variables in unused register banks. Also the SSEG is placed
9054 wherever there is enough space for it, and IDATA can be anywhere
9055 in internal RAM. For now compile using -Wl-Y[stack_size].
9056 The mem file is different for this option as well, since it
9057 makes no sense of talking about DSEG lenght.
9059 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9061 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9062 in certain cases, e.g. when ROM assignment, patch provided
9063 from Albert den Haan.
9065 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9235 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9237 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

9308 it breaks with bitfields, extern declarations, and gcse analysis.
9309 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9310 could be assigned through a pointer, so don't complain.

10070 copied from genNearPointerSet()
10071 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10072 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10073 If they pop r0/r1 they must be called in the opposite order than aopOp().
10074 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10075 (resp. --stack-auto), prepared for --xstack

10088 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10089 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10090 type for bits was changed. It resulted in bit variables becoming
10091 global, which is not permitted in PIC 14 assembly output.
10093 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10095 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10108 A few small changes that speed up the peephole optimizer.
10112 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10114 Try to make the peephole optimizer smarter by maintaining
10115 an association between the assembly source code and the
10116 iCodes that originated them. Put this information to use
10117 with a new peephole rule condition "notVolatile" so that
10118 the rules can be aggressive yet still safe.
10123 * src/mcs51/peeph.def
10125 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10129 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10130 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10131 if the left or right operand symbols have the accuse flag set.
10133 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10135 Changed the type of the result of the ! (NOT) operator to char;
10136 previously it returned the same type as the source. This allows
10137 us to eliminate all the genFloatNot functions (all of its target
10138 implementations were very buggy) since !float can use the same
10141 * src/SDCCicode.c (ast2iCode): ! returns char

10150 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10151 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10152 during interrupts. Ensure WSAVE is located at a shared bank address.
10153 2. Fixed page selection in some places
10154 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10155 the registers name strings.
10156 4. Fixed "signed / unsigned compare" compiler warnings.
10157 5. The PIC port manages its own allocation of the general purpose
10158 registers, but makes no attempt to reuse them. As a result when
10159 compiling it soon runs out of general purpose registers. Some
10160 additional code was added to the files pcode.c and device.c to walk
10161 through the function call tree and rename the registers so that they
10171 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

10180 Made bitfield a distinct type from bit so that bitfields
10181 convert as per ANSI C and bits retain their traditional
10182 boolean style behaviour. Implemented bitfield support in
10190 * src/ds390/gen.c: bit v bitfield split
10191 * src/z80/gen.c: New support for bitfields
10192 * support/regression/tests/bitfields.c: reenabled z80,
10195 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10206 for literal assignments in genPackBits (thanks to Frieder for
10212 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10214 Fixed bug #748310 (pointer to function type mishandled when the
10215 function name is omitted). Also fixed a SIGSEGV when a function
10216 attribute (reentrant, etc) is used on a non-function or on a
10217 function but misplaced before the parameter list.

10244 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10246 Made the constant following the "interrupt" keyword optional. If
10247 omitted, the function will not automatically be given an entry
10248 in the interrupt vector table (similar to #pragma NOIV, but
10249 less syntacticly kludgy). The interrupt number is also now
10250 range checked. Also fixed a bug in the high order bit example

10726 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10727 the regression tests I'm not brave enough to enable 245.b, 245.c
10728 * doc/sdccman.lyx: added latex preamble for hyperref package.
10729 Using pdflatex this will give you a hyperlinked pdf file with

10780 added if/endif conditional macros to remove options help
10781 messages from optionsTable when a port is not configured, added
10782 support for the PIc16 port in the ports table, when executing
10783 the compiler with no port specified on command line, a default
10784 port is selected with the new macro DEFAULT_PORT which is
10785 defined in port.h, in setDefaultOptions() linkOptions is removed
10786 from initialization assignment, since now it is a set,
10787 parseCmdLine uses setParseWithComma for linkOptions, in
10788 linkEdit() linkOptions are accessed with new function indexSet()
10789 which returns the i'th item of a set variable. See SDCCset.c, in
10790 linkEdit() when calling buildCmdLine(), added linkOptions as
10791 last argument. Now users can pass arguments to gplink via the
10792 -Wl option, main() uses pic16glue() to glue up pic16 programs
10793 * src/SDCCpeeph.c: various changes to support pic16
10794 * src/SDCCset.c: added function void *indexSet(set *, int) to

10804 * src/pic16/glue.c: commented out some error producing lines
10805 * src/pic16/main.c: __config directives are commented out to stop
10806 gpasm complaining and test the linkage with gplink, _linkCmd and
10807 _asmCmd changed to be more gplink and gpasm friendly
10808 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10809 produced an error when parsed, peep rule 12 is added to utilize
10810 movff, but it is commented out since the pCode does not support
10811 yet a command with 2 address arguments
10813 2003-05-18 <johan AT balder>
10815 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11876 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11878 * in /sdcc/as/mcs51/ changed these files in order to create an
11879 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11880 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11881 following files to include the previous two files: aslink.dsp,
11882 Makefile.aslink, Makefile.bcc, and Makefile.in.
11884 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11885 .adb instead of .cdb
11887 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11889 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11890 value from option --iram-size.
11892 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11894 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11897 2002-09-18 <wiml AT hhhh.org>
11899 * SDCClrange.h: exposed setFromRange() and setToRange()
11900 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11901 packRegsForAccUse() (bug 542397)
11902 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11903 multiple times and emitting the fetch operations more than once
11904 added aopGetUsesAcc() function to allow binary operators to
11905 fetch their operands in the correct order; made genMinus() emit
11906 compact code for X = LITERAL - Y
11908 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11909 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11910 sprintf() in line 1267.
11912 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11913 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11916 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11917 Changes to aslink (All the changes are marked with 'JCF'):
11919 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11922 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11923 area BSEG. Also moves, if possible, the DATA area down into the internal
11924 ram so more space is available.
11926 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11929 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11930 not bytes. Function summary() which creates a memory usage summary
11931 file with extension .mem. Reports of overlaping stack and small stack
11932 size. If the space for the stack is less than 16 bytes aslink trows a
11935 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11936 the 8051. Option 'y' for memory summary output file.
11938 Changes to sdcc (All the changes are marked with 'JCF'):
11940 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11942 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11943 overlaying area for it (uses RegBankUsed[4]).
11945 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11946 bank zero as used by default. By default aslink locates the stack
11947 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11948 the creation of the .mem file. Delegates the allocation of data area
11949 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11950 the begining of the stack area to aslink.
11952 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11953 glue() in SDCCglue.c creates an area for it.
11955 2002-09-03 Borut Razem <borut.razem AT siol.net>
11956 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11957 sdcc/src/pic/glue.c:
11958 introduced atexit() handler for teporay files removal in case of
11959 errors, assertions, ...
11961 2002-08-29 Borut Razem <borut.razem AT siol.net>
11962 * sdcc/support/cpp2/auto-host_vc_in.h:
11963 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11964 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11965 Maybe there is a similar problem with BORLANDC? It should be checked!
11967 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11968 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11969 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11970 was not executed, and the compiler (cl) launched a warning:
11971 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11973 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11974 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11976 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11977 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

11985 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11986 - added Release configuration in VS projects
11987 - review of compiler an linker options
11988 - VC .exe files are generated in bin_vc directory, not to interfere
11989 with binaries generated from other projects (cygwin, mingw, bcc ...)
11991 * sdcc/src/yacc.dsp: added
11993 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11994 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11995 and insert the version number definitions from .version
11997 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11999 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

12011 2002-08-10 Borut Razem <borut.razem AT siol.net>
12012 * src/SDCCmain.c (main):
12013 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12014 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12015 The consequence was that some temporary files were not removed.
12018 unification of code in functions tempfilename() and tempfile():
12019 function tempnam() is defined in Visual Studio 6.0 and .NET
12021 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12023 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,

12039 added return 0 statements after assert() to make compiler happy
12041 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12042 added newline in the def file to keep MSC compiler satisfied
12044 * sdcc/src/z80/gen.c:
12045 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12046 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12047 - solved MSC error in function aopDump()
12049 * sdcc_vc.h: define PREFIX as "\\sdcc"

12226 * sdcc/src/SDCCloop.c:
12227 Previous fix was not good. basic blocks that have "break" or "return" are
12228 not really partof a loop , but live ranges used in these blocks should
