2085 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2087 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2088 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2090 One basic decision: e.g. src/clean.mk includes further files. In order
2091 to make this work there are two solutions:
2092 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2093 run configure on them. This way they can use
2094 'include $(srcdir)/port-clean.mk'
2095 - always include clean.mk by the Makefile at the same level. To avoid
2096 that `make clean` tries to include and build Makefile.dep the
2097 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2098 implemented, because now even `make uninstall` doesn't create
2099 Makefile.in. clean.mk could be eliminated by pasting it in
2102 * debugger/mcs51/Makefile.in: build own objects from library sources
2103 (SLIB, SDCC) in current directory
2105 * configure, configure.in: renamed --disable-device-lib-build in
2106 --disable-device-lib; added --enable-doc, the required tools are
2107 searched by configure; added result message; the toolchain for the
2108 belonging ports are now only built, if the port is enabled.
2110 * support/regression/*: all output is written in directory gen, because
2111 the fwk and ports directories don't livet in the build tree using vpath
2113 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2114 --disable-device-lib, added --enable-doc, added section VPATH
2116 * sim/ucsim/configure.in,
2117 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2118 z80 are enabled by default
2120 2006-04-24 Raphael Neider <rneider AT web.de>
2122 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2123 to config word, "pic14_"-prefixed some extern functions
2124 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2125 config word has been found
2126 * src/pic/device.h: added prototypes
2127 * src/pic/pcode.c: added "pic14_"-prefix where needed
2128 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2130 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2133 (pic14createInterruptVect): moved generating __config directives away

2143 registers that have not been assigned proper liveranges,
2144 fixes #1469504 and #1474602,
2145 (pCodeRegOptimizeRegUsage): fixed typo in comment
2147 2006-04-24 Borut Razem <borut.razem AT siol.net>
2149 * device/examples/main8051.c: deleted - it was removed from CVS
2150 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2151 after the transition to Subversion
2152 * src/SDCCalloc.h: deleted - it was removed from CVS
2153 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2391 implemented patch 1120823 Thanks to Willy De la Court (normal
2392 interrupts need an interrupt number now if they are made critical),
2393 and enabled nesting of critical functions though not for gbz80
2394 (genCritical, genEndCritical): added functions
2395 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2396 * src/z80/mappings.i: added "ei" to all mappings

2408 the left operand is shorter than the result (c* = lit-c* + int),
2410 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2413 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2415 * src/.version: increased version number to 2.5.5
2416 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2417 linking is done manually in pic16 port's _linkEdit,
2418 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2419 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2420 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2421 allocate asmop as AOP_ACC,
2422 (aopForRemat): added parameter 'bool result' in function declaration,
2423 (pic16_aopGet): return AOP_ACC when accessing WREG,
2424 (pic16_popGetTempReg): minor modification,

2435 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2436 call to allocReg, not by manually allocating a new one,
2437 (pic16_assignRegisters): now before going through the register
2438 allocating functions mark all registers as free. This eliminates some
2439 side effects resulting from peephole parser done earlier in the backbone
2441 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2499 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2500 which dumps before the function entry point a data byte which represents
2501 the number of the local variables used by the specified function, added
2502 'xinst' for initial support for Extended Instruction Support,
2503 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2504 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2505 port->fun_prefix anymore (may change later),
2506 (genFunction, genEndFunction): do not store/restore local registers for
2507 _main (this should take care the --main-return command line option in
2509 (genOr): removed some legacy pic-port instructions,
2510 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2511 performing operations with SFR's causes data to be written more than
2512 once to each SFR. Perhaps SFRs should be handled in special cases...
2513 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2515 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2516 into account for stack starting position,

2518 --extended or -y for Extended Instruction Support,
2519 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2520 (deassignLRs): *** perhaps the most important change, old 'for' code
2521 (commented out for reference), didn't account for some registers which
2522 were left marked 'not free' after a pointer operation. The change
2523 reduces register usage a lot in some cases
2525 2006-03-04 Borut Razem <borut.razem AT siol.net>

4798 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4799 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4800 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4801 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4802 always available in leading double underscore form. The C99 support is
4803 mostly missing, but it's a start.
4804 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4805 reserved identifier "__data".
4807 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4883 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4885 * device/lib/printf_large.c: removed inline assembly for portability and
4886 readability. Use printf_fast if speed or size are more important.
4887 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4888 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4890 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4892 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4893 prevent compiler warning
4895 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4897 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4898 moved to level 0 and declared as static. Also they are explicit
4899 placed in access bank. This was necessery because some times they
4900 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4901 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4902 optimizations. Currently only compare to unsigned char is implemented,
4903 * src/pic16/gen.c: added fReturnIdx array,
4904 * (struct resolvedIfx) is moved to gen.h and made public,
4905 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4906 * (aopForSym): added an optimization to directly store in stack of
4907 the operand of a SEND iCode,
4908 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4909 but as registers instead (AOP_REG) using the fReturnIdx array,
4910 * (pic16_freeAsmop): remove the freed register from the
4911 _G.sregsAlloc field,
4912 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4913 a compare of 'WREG',
4914 * (pic16_popGetTempRegCond): changed function prototype, now
4915 function takes also a bitVector argument v which holds the current
4916 set of registers that are allocated for stack access by aopForSym,
4917 registers allocated in aopForSym for accessing stack symbols are not
4918 any more part of the functions usedRegs field,
4919 * (genCall): some times aopOp is called for a stack variable to be
4920 send, aopForSym might perform the push, if this is true make sure
4921 that genCall doesn't push the variable twice by testing _G.resDirect,
4922 * (genFunction): changed testing for unspecified interrupt number
4923 from 256 to INTNO_UNSPEC,
4924 * modified selection scheme of frame pointer generation. Previously
4925 if function did use local registers a frame pointer was generated,
4926 now a frame pointer is generated only if function has arguments
4927 (that need PLUSW2 register access), or has stack arguments, or the
4928 compiler is not instructed to omit the frame pointer,
4929 * (genEndFunction): before restoring local registers that were saved
4930 in the function preamble, also restore the registers that *might*
4931 have been allocated for stack access,
4932 * (genRet): removed some old comments,
4933 * (genCmp, the active (RN's) version): added a call to the
4934 pic16_genCmp_special function to perform the compare with a more
4935 robust and optimized way,
4936 * (genInline): a feature has been added in inline code generation,
4937 which allows a wildcard variable substitution when writing inline
4938 assembly. Code is incomplete and experimental therefore undocumented,
4939 * (genCast): changed order of aopOp for result and right to allow
4940 aopForSym to directly load the result if possible,
4941 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4942 perform an optimized compare on some selected special occasions,
4943 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4944 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4945 generate an IVT any more,
4946 * src/pic16/main.c (pic16_optionsTable): added command line option
4948 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4949 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4951 * src/pic16/NOTES: Raphael Neider added in list of active developers
4952 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4953 jumptable_end to prevent bug #,
4954 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4955 inCond and outCond fields,
4956 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4957 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4958 turn off register spilling,
4959 * (packRegsForOneUse): synced with other ports' versions although it
4960 is not used currently,
4961 * (pic16_packRegisters): added an optimization while reading
4962 structure bitfields, some registers may be saved (malloc code is
4963 decreased by 80 bytes)
4965 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4967 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4968 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4969 this can be optimized more?
4971 2005-03-10 Raphael Neider <rneider AT web.de>
4973 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4974 genNearPointerGet): (hopefully) fixed access to bitfields via
4975 pointers (p->bitN = x; and x = p->bitN; failed)
4977 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5592 (setFromConditionArgs): friendly operand parser for peephole rules,
5593 (operandBaseName, operandsNotRelated): new peephole condition
5594 "operandsNotRelated" -- similar to "operandsNotSame", but takes

5607 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5609 Adding support for replacing ljmps with sjmps in jumptables
5610 generated for switch statements. For now you need to set the
5611 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5612 Now 4 algorithms for mcs51 jumptable generation are used:
5613 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5614 addresses loaded pc-relative for up to 112 cases and stack-pushing
5615 target addresses loaded with offset from dptr for up to 256 cases.

5641 Large cummulative patch for pic16 port.
5642 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5643 to call when a stack overflow occurs,
5644 * (malloc.h): added CVS Id tag,
5645 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5647 * added libc directory. The current version of LibC contains string
5648 functions, ctype functions and macros and some functions of the
5649 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5650 be extensively tested in the future. Standard disclaimer here.
5651 Library is not automatically build yet. But one can build it by
5652 invoking 'make' inside the libc directory.
5653 * added ADC library under libio. Preliminary version yet.
5655 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5662 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5663 * (pic16_storeForReturn): optimized return of 0,
5664 * (genCmp): experimental code for new genCmp which uses PIC18's
5665 special compare&skip instructions. Initial tests fail some times
5666 with variables grater than 1 byte in size, so new code is disabled,
5667 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5669 * (genCast): began a fix to optimize the casting of a bit to another
5670 bit, now assigning a bitfield to another bitfield will fail, sorry,
5671 * src/pic16/main.c: disabled the use of lr-support feature,
5672 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5673 * added some function prototypes, added function _debugf prototype,

5675 bits with offset (case PO_GPR_BIT),
5676 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5678 * (isBankInstruction): modified to return 0 for no banking instruction,
5679 and 1 for banking instruction,
5680 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5681 caused stop processing pCodes after a inline assembly block,
5682 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5683 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5684 registers when it shouldn't,
5685 * src/pic16/ralloc.c (allocReg): add preliminary support for
5686 supporting a limited set of temporary registers,
5688 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5690 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5691 genDataPointerSet): ensure assignments always copy in MSB to LSB
5693 (loadRegFromAop): recognize CLRH optimization,
5694 (genFunction): optimize RECEIVE iCodes in reentrant functions
5696 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5698 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5699 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5701 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5712 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5714 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8693 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8695 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8696 loaded with the linker search paths (-L arguments) and the libraries
8697 to be linked with the current source (-l arguments). Changes
8698 currently will affect only the pic16 port.
8699 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8700 include path the port specific paths and port specific libraries,
8701 * gplink command now contains the $3 argument,
8702 * src/pic16/device.h,
8703 * src/pic16/device.c,: structure PIC_device is made public and
8704 renamed to PIC16_device, the same for variable Pics which is renamed
8705 to Pics16. Updated all references to them.
8706 * src/pic16/glue.c (pic16glue): corrected bug with code
8707 initialization which bypassed the variable initializations block.
8709 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8710 COMPILE_FLAGS and added the --nostdinc option
8712 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8714 * device/include/mc68hc908jb8.h: Register defs for another member

8717 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8719 Documenting changes from previous commits.
8720 * configure.in (version 1.56),
8721 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8722 when generating output files to configure the pic16 library,
8723 but now I've commented it out, since gputils aren't installed in the
8724 SF compile farm, so library won't compile
8726 * device/lib/Makefile.in (version 1.56): initially I've added in
8727 target 'all' the prerequestive 'model-pic16' so it compiled the
8728 pic16 library, but now I've commented it out for the same reasons
8730 * added targets 'model-pic16' and 'objects-pic16' to compile the
8732 * added target 'port-specific-objects-pic16' to handle the
8733 generated libraries and copy them into the build/ directory
8734 * added target 'clean-intermediate-pic16' to clean intermediate
8735 files into pic16 directory
8736 * in target 'installdirs' added line to create directory pic16 in
8737 the installation path
8739 * device/include/Makefile.in (version 1.11): in target 'install'
8740 added lines to copy all header files to installation path,
8741 * in target 'installdirs' added line create directory for pic16
8742 headers in the installation path
8744 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

8757 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8758 option so that it actually works. Made it specific to the z80, since
8759 the gbz80 doesn't have these kinds of I/O ports.
8761 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8763 * device/include/z180.h,

8772 portmode; added deprecation warning for bank= and protmode= forms.
8773 Also, guard against buffer overflow.
8774 * src/z80/gen.c (aopGet): generate better code for sfr banked read
8776 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8778 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8779 changed interrupt vector table generation to only emit declared vectors.
8780 * device/include/Makefile.in: added missing backslash
8781 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
8783 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8785 Mainly changes to support compilation of the device libraries
8786 * src/pic16/device.c: stack is allocated via symbol and not
8787 via literal number. The symbol is placed in the corresponding
8788 position of the data ram
8789 * (pic16_dump_section): relocatable and absolute uninitialized
8790 data are now emitted in sorted order to reduce section naming,
8791 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8792 weren't marked as being in the access bank,
8794 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8796 Added portion of GNU PIC Library under the directory
8797 device/include/pic16 and device/lib/pic16. These files
8798 contain the declarations of SFRs for the PIC18Fxx2 devices.
8799 The directory is initialized via configure from toplevel.
8801 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8803 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8804 the spilllocations to be compared correctly
8806 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8808 * src/SDCCast.c (decorateType): fixed bug introduced today
8810 2004-01-12 Borut Razem <borut.razem AT siol.net>
8812 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8815 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8817 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8818 in simpler and even better code
8820 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8822 * src/SDCCicode.c (operandOperation): fixed bug #874819

8826 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8828 * doc/sdccman.lyx: Moved and added some sections, small changes
8829 all over. Telling LaTeX to be less strict with word spacing
8830 to better keep the right margin. Changed some notes about
8831 maintainance of the ports in section 3.2.1 - is it OK like this?
8833 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8835 SDCC source changes:
8836 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8869 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8870 UPPER for immediate operands,
8871 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8873 * src/pic16/peeph.def: all peepholes with movff are commented out,
8874 because there is a problem in the pcode peep optimizer,
8875 * src/pic16/ralloc.c: the register allocator can now reuse local
8876 function symbols for another function. This saves register usage.
8877 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8879 Added file src/pic16/NOTES with information about program writing on
8880 the current port version.

8889 * src/SDCCmain.c : fixed #872250: -l command line defined library
8890 files are scanned before standard library files
8892 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8909 gen51Code): more efficient parameter receive for --model-large
8912 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8915 * src/z80/main.c: added missed needLinkerScript flags (more than
8916 one port structure defined in these file)
8917 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
8920 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

8933 needLinkerScript flag
8935 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8936 * src/pic/glue.c: added variable udata_section_name to
8937 override default uninitialized data segment definition for
8938 devices only with SHAREBANK memory (reported from Erik Epetrich)
8939 * (pic14emitOverlay): modified to emit a commented overlay segment
8940 directive when no overlay data exist
8941 * (picglue): modified to emit uninitialized data segment
8942 according to udata_section_name

8947 arguments via -W option
8948 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8949 object file from '.rel' to '.o' in port->linker structure,
8950 changed size of fptr from 2 to 3 in port structure
8952 2004-01-07 Borut Razem <borut.razem AT siol.net>
8954 * support/scripts/sdcc.nsi: update PATH
8955 * support/scripts/sdcc.ico: craeted
8957 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

8960 * doc/Makefile: fix install
8962 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8964 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8966 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
8967 how the function variable allocation summary is displayed; also
8968 include information about variables allocated to the overlay
8971 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8973 * as/mcs51/lkmain.c: Help about -Y option

8985 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8987 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8988 (default behaviour).
8990 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8992 A python script to validate compiler diagnostic messages. It can be
8993 used to verify that sdcc complains about bad c source code and
8994 gives a good location of the error.
8995 * support/valdiag/Makefile,
8996 * support/valdiag/valdiag.py,
8997 * support/valdiag/tests/*
8999 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9001 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9002 * src/SDCCsymt.c (newEnumType),
9004 * support/Util/SDCCerr.c,

9010 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9012 * src/common.h: added ifndef/define/endif macros
9013 around the header file.
9014 Bug reported from Jesus Calvino-Fraga
9016 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9018 * sdcc.spec: updated
9019 * device/include/Makefile.in: don't install CVS directories
9020 * device/lib/Makefile.in: added removal of CVS directories after install
9021 * doc/Makefile: fixed install, added local_icons
9022 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9023 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9024 * src/ds390/gen.c (genRightShift): fixed bug #870788
9025 * src/SDCCast.c (decorateType): fixed bug #870781
9027 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9029 PIC16 port related changes:
9030 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9031 added variable stackPos,
9033 * gen.c: genCall, assignResultValue: added support for
9034 pushing/retrieving function parameters to/from stack,
9035 genFunction,genEndFunction: setup stack frame for the
9037 genAddrOf: will be changed according to bug 863624
9039 * added files genutils.c and genutils.h which contain gen*
9040 debugged and optimised functions extracted from gen.c
9042 * glue.c: added variable 'externs' which holds extern symbols,
9043 pic16emitRegularMap: is modified to properly handle relocatable
9044 symbols under the new scheme,
9045 pic16createInterruptVect: is modified
9046 pic16printPublics: is modified to emit 'global' assembler directives,
9047 added pic16_printExterns to print extern symbols,
9048 pic16glue: initializes stack/frame pointer in the beginning of
9049 the assembly output. Temporary hack, will be corrected later,
9050 because gplink yet does not support stack and SDCC does not
9051 yet support a type of crt0.o object to create the final binary.
9053 * Removed many lines that contain 8051 legacy code.
9054 * The code is finally placed under a 'code' directive.
9055 * Added port specific options.
9057 * _process_pragma: simplified since now we do not need *special*
9058 include file to define SFR registers. But a separate header
9059 will be needed. This will be developed later.
9060 * _pic16_parseOptions: added, parses port specific options:
9061 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9062 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9063 --preplace-udata-with=
9065 * _pic16_setDefaultOptions: modified to initialize section names,
9066 but hack is temporarly out of order since it needs improvement.
9067 * _pic16_genAssemblerPreamble: configuration words are emitted by
9068 their address instead of their name. This part is incomplete and
9069 supports only the 18Fxx2 devices. Other devices will emit an error
9070 during assembly since they do not contain the same set of config
9072 * _pic16_genIVT: is modified,
9074 * pcode.c: added definitions for some hardware registers that are needed
9076 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9077 All PCI entries are updated. Now LFSR is supported.
9078 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9079 * added pic16_newpCodeOpLit2 to support instructions with
9080 two literal arguments
9081 * pic16_pCode2str: corrected code that emits assembler instructions
9082 with two literal operands and those that have an access bit modifier
9083 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9084 this fixes a bug which caused some labels to be lost, when an
9085 assembler directive was added, i.e. banksel,
9086 * pic16_FixRegisterBanking: improved logic that causes the insertion
9088 * InlineFunction: functions that are called once, are not any more
9089 inlined. This can be a port option in the future,
9091 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9093 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9094 hold the corresponding uninitialized symbols,
9095 * pic16_allocProcessorRegister: registers have explicit marked the
9097 * pic16_allocInternalRegister: registers are explicit marked as
9099 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9100 processing list, so bit registers were lost,
9103 * ralloc.h: added field 'accessBank' and original symbol operand
9104 in register definition,
9105 * removed the field isMapped from register definition,
9107 ** Several functions have been removed from various sources:
9108 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9109 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9110 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9111 pic16_assignRelocatableRegisters
9113 ** others have been introduced:
9114 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9115 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9117 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9119 * support/scripts/inc2h.pl: changed definition of BIT_AT
9120 to emit 'sbit at' instead of 'bit at'. This was a request.
9122 PIC16 port related preliminary changes:
9123 * gen.c: prefixed function popRegFromString with
9124 pic16_ and all references to it corrected
9125 * pcode.c: all pic16_pc_* hardware registers prefixed
9126 with underscore (_),
9127 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9128 * ralloc.c: newReg(): when register is REG_SFR then
9129 set address to rIdx,
9130 pic16_allocProcessorRegister(): marks register wasUsed=0
9131 pic16_writeUsedRegs(): added a call to assign processor
9132 registers via pic16_assignFixedRegisters
9134 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9136 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9137 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9138 variables in unused register banks. Also the SSEG is placed
9139 wherever there is enough space for it, and IDATA can be anywhere
9140 in internal RAM. For now compile using -Wl-Y[stack_size].
9141 The mem file is different for this option as well, since it
9142 makes no sense of talking about DSEG lenght.
9144 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9146 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9147 in certain cases, e.g. when ROM assignment, patch provided
9148 from Albert den Haan.
9150 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10155 copied from genNearPointerSet()
10156 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10157 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10158 If they pop r0/r1 they must be called in the opposite order than aopOp().
10159 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10160 (resp. --stack-auto), prepared for --xstack
10162 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10164 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10166 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10168 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10169 these ports have their own __sdcc_external_start()
10171 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10173 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10174 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10175 type for bits was changed. It resulted in bit variables becoming
10176 global, which is not permitted in PIC 14 assembly output.
10178 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10180 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10182 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10184 Z80 and MCS51 linkers complaint if a public symbol is defined
10185 in more than one library module:

10193 A few small changes that speed up the peephole optimizer.
10197 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10199 Try to make the peephole optimizer smarter by maintaining
10200 an association between the assembly source code and the
10201 iCodes that originated them. Put this information to use
10202 with a new peephole rule condition "notVolatile" so that
10203 the rules can be aggressive yet still safe.
10208 * src/mcs51/peeph.def
10210 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10214 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10215 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10216 if the left or right operand symbols have the accuse flag set.
10218 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10220 Changed the type of the result of the ! (NOT) operator to char;
10221 previously it returned the same type as the source. This allows
10222 us to eliminate all the genFloatNot functions (all of its target
10223 implementations were very buggy) since !float can use the same
10226 * src/SDCCicode.c (ast2iCode): ! returns char
10227 * src/mcs51/gen.c (genNot, genNotFloat),
10228 * src/ds390/gen.c (genNot, genNotFloat),
10229 * src/z80/gen.c (genNot, genNotFloat),
10230 * src/pic/gen.c (genNot, genNotFloat),
10231 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10235 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10236 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10237 during interrupts. Ensure WSAVE is located at a shared bank address.
10238 2. Fixed page selection in some places
10239 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10240 the registers name strings.
10241 4. Fixed "signed / unsigned compare" compiler warnings.
10242 5. The PIC port manages its own allocation of the general purpose
10243 registers, but makes no attempt to reuse them. As a result when
10244 compiling it soon runs out of general purpose registers. Some
10245 additional code was added to the files pcode.c and device.c to walk
10246 through the function call tree and rename the registers so that they
10256 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10257 genPlus() & genMinus() when the result is the same as left or right
10259 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10263 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10265 Made bitfield a distinct type from bit so that bitfields
10266 convert as per ANSI C and bits retain their traditional
10267 boolean style behaviour. Implemented bitfield support in
10275 * src/ds390/gen.c: bit v bitfield split
10276 * src/z80/gen.c: New support for bitfields
10277 * support/regression/tests/bitfields.c: reenabled z80,
10280 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10282 Rules 246.x, 247.x relate to bitfields, the others speed up
10283 access to xdata mapped I/O devices.
10285 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10287 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10289 Cleaned up genPackBits and genUnpackBits and added two helper
10290 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10291 for literal assignments in genPackBits (thanks to Frieder for
10297 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10299 Fixed bug #748310 (pointer to function type mishandled when the
10300 function name is omitted). Also fixed a SIGSEGV when a function
10301 attribute (reentrant, etc) is used on a non-function or on a
10302 function but misplaced before the parameter list.
10304 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10306 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10307 * support/Util/SDCCerr.h,
10308 * support/Util/SDCCerr.c: Added func attr misuse error msg
10310 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10312 Fixed bug #787649 by anonymous
10313 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10314 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10316 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10318 Fixed numerous bitfield problems.

10329 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10331 Made the constant following the "interrupt" keyword optional. If
10332 omitted, the function will not automatically be given an entry
10333 in the interrupt vector table (similar to #pragma NOIV, but
10334 less syntacticly kludgy). The interrupt number is also now
10335 range checked. Also fixed a bug in the high order bit example

10351 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10353 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10354 be re-activated by defining REDUCE_LITERALS)
10355 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10356 unsigned, but are signed by default
10357 * src/SDCCval.c (constVal): rearranged
10358 * src/SDCCval.c (valMod): preliminary fix
10359 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10811 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10812 the regression tests I'm not brave enough to enable 245.b, 245.c
10813 * doc/sdccman.lyx: added latex preamble for hyperref package.
10814 Using pdflatex this will give you a hyperlinked pdf file with
10815 bookmarks. (prepend '%' before /usepackage if this breaks something)

10865 added if/endif conditional macros to remove options help
10866 messages from optionsTable when a port is not configured, added
10867 support for the PIc16 port in the ports table, when executing
10868 the compiler with no port specified on command line, a default
10869 port is selected with the new macro DEFAULT_PORT which is
10870 defined in port.h, in setDefaultOptions() linkOptions is removed
10871 from initialization assignment, since now it is a set,
10872 parseCmdLine uses setParseWithComma for linkOptions, in
10873 linkEdit() linkOptions are accessed with new function indexSet()
10874 which returns the i'th item of a set variable. See SDCCset.c, in
10875 linkEdit() when calling buildCmdLine(), added linkOptions as
10876 last argument. Now users can pass arguments to gplink via the
10877 -Wl option, main() uses pic16glue() to glue up pic16 programs
10878 * src/SDCCpeeph.c: various changes to support pic16
10879 * src/SDCCset.c: added function void *indexSet(set *, int) to

10889 * src/pic16/glue.c: commented out some error producing lines
10890 * src/pic16/main.c: __config directives are commented out to stop
10891 gpasm complaining and test the linkage with gplink, _linkCmd and
10892 _asmCmd changed to be more gplink and gpasm friendly
10893 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10894 produced an error when parsed, peep rule 12 is added to utilize
10895 movff, but it is commented out since the pCode does not support
10896 yet a command with 2 address arguments
10898 2003-05-18 <johan AT balder>
10900 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11987 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11988 multiple times and emitting the fetch operations more than once
11989 added aopGetUsesAcc() function to allow binary operators to
11990 fetch their operands in the correct order; made genMinus() emit
11991 compact code for X = LITERAL - Y
11993 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11994 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11995 sprintf() in line 1267.
11997 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11998 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12001 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12002 Changes to aslink (All the changes are marked with 'JCF'):
12004 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12007 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12008 area BSEG. Also moves, if possible, the DATA area down into the internal
12009 ram so more space is available.
12011 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12014 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12015 not bytes. Function summary() which creates a memory usage summary
12016 file with extension .mem. Reports of overlaping stack and small stack
12017 size. If the space for the stack is less than 16 bytes aslink trows a
12020 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12021 the 8051. Option 'y' for memory summary output file.
12023 Changes to sdcc (All the changes are marked with 'JCF'):
12025 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12027 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12028 overlaying area for it (uses RegBankUsed[4]).
12030 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12031 bank zero as used by default. By default aslink locates the stack
12032 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12033 the creation of the .mem file. Delegates the allocation of data area
12034 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12035 the begining of the stack area to aslink.
12037 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12038 glue() in SDCCglue.c creates an area for it.
12040 2002-09-03 Borut Razem <borut.razem AT siol.net>
12041 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12042 sdcc/src/pic/glue.c:
12043 introduced atexit() handler for teporay files removal in case of
12044 errors, assertions, ...
12046 2002-08-29 Borut Razem <borut.razem AT siol.net>
12047 * sdcc/support/cpp2/auto-host_vc_in.h:
12048 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12049 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12050 Maybe there is a similar problem with BORLANDC? It should be checked!
12052 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12053 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12054 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12055 was not executed, and the compiler (cl) launched a warning:
12056 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12058 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12059 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12061 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12062 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12064 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12065 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12066 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12067 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12068 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12069 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12070 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12071 - added Release configuration in VS projects
12072 - review of compiler an linker options
12073 - VC .exe files are generated in bin_vc directory, not to interfere
12074 with binaries generated from other projects (cygwin, mingw, bcc ...)
12076 * sdcc/src/yacc.dsp: added
12078 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12079 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12080 and insert the version number definitions from .version
12082 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12084 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12085 added - genarate auto-host.h using auto-host_vc_in.h as template
12088 removed from CVS, generated automatically
12090 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12091 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12093 2002-08-11 Borut Razem <borut.razem AT siol.net>
12094 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12096 2002-08-10 Borut Razem <borut.razem AT siol.net>
12097 * src/SDCCmain.c (main):
12098 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12099 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12100 The consequence was that some temporary files were not removed.
12103 unification of code in functions tempfilename() and tempfile():
12104 function tempnam() is defined in Visual Studio 6.0 and .NET
12106 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12108 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12109 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12110 - removed compiler command line option /WX: Treats all warnings as errors
12111 - update a list of source files, included into the project
12113 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12114 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12115 changed project type to Generic Project so that can be correcly converted to VS.NET project
12117 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12119 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12121 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12123 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12124 added return 0 statements after assert() to make compiler happy
12126 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12127 added newline in the def file to keep MSC compiler satisfied
12129 * sdcc/src/z80/gen.c:
12130 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12131 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12132 - solved MSC error in function aopDump()
12134 * sdcc_vc.h: define PREFIX as "\\sdcc"
12136 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12137 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12140 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12141 - Rewrote the register banking algorithm.
12142 - Added pCode live-range analysis to registers (for now, only non-used and
12143 singly-used registers optimized away)
12145 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12147 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

12174 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12176 2002-03-28 Johan Knol <johan AT balder>
12178 * src/SDCCval.c: fixed bug #532436
12180 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12182 Added "char *Processor" field to the port structure.
12185 Added -p option. Allows port dependent processor to be specified.
12188 Initialized the new field char *Processor field to NULL in all ports
12191 Compiler generated registers for interrupt context saving
12192 were not getting allocated.
12194 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12197 Fixed left shift. Will promote the left side of a left shift
12198 if a) left shifting more than size of operand or b) when assigned
12199 to something size > size of left side
12201 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12205 analysis is restructured. ...
12207 * src/pic/device.h:
12210 * src/pic/device.c:
12211 Added. device.c is a PIC port hack to accomodate variations
12214 2002-03-13 Michael Hope <michaelh AT vroom>
12216 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12218 2002-03-04 johanknol <johanknol AT manik>
12220 * /src/SDCCval.c: fixed
12222 const unsigned char arr[][2] = { { 0, 1 } };

12309 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12311 * sdcc/src/SDCCloop.c:
12312 Previous fix was not good. basic blocks that have "break" or "return" are
12313 not really partof a loop , but live ranges used in these blocks should
12314 be live thru the entire loop, so set partOfLoop but don't add them to
12317 2002-02-21 <johan AT FRIJA>
12319 * src/SDCCcse.c: fixed bug #514308
12321 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
