2125 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2127 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2128 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2130 One basic decision: e.g. src/clean.mk includes further files. In order
2131 to make this work there are two solutions:
2132 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2133 run configure on them. This way they can use
2134 'include $(srcdir)/port-clean.mk'
2135 - always include clean.mk by the Makefile at the same level. To avoid
2136 that `make clean` tries to include and build Makefile.dep the
2137 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2138 implemented, because now even `make uninstall` doesn't create
2139 Makefile.in. clean.mk could be eliminated by pasting it in
2142 * debugger/mcs51/Makefile.in: build own objects from library sources
2143 (SLIB, SDCC) in current directory
2145 * configure, configure.in: renamed --disable-device-lib-build in
2146 --disable-device-lib; added --enable-doc, the required tools are
2147 searched by configure; added result message; the toolchain for the
2148 belonging ports are now only built, if the port is enabled.
2150 * support/regression/*: all output is written in directory gen, because
2151 the fwk and ports directories don't livet in the build tree using vpath
2153 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2154 --disable-device-lib, added --enable-doc, added section VPATH
2156 * sim/ucsim/configure.in,
2157 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2158 z80 are enabled by default
2160 2006-04-24 Raphael Neider <rneider AT web.de>
2162 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2163 to config word, "pic14_"-prefixed some extern functions
2164 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2165 config word has been found
2166 * src/pic/device.h: added prototypes
2167 * src/pic/pcode.c: added "pic14_"-prefix where needed
2168 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2170 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2172 (pic14emitRegularMap): ignore config words,
2173 (pic14createInterruptVect): moved generating __config directives away
2174 (picglue): have __config directives emitted
2176 2006-04-24 Borut Razem <borut.razem AT siol.net>
2178 * doc/Makefile: sync with nightly build makefile
2180 2006-04-24 Raphael Neider <rneider AT web.de>
2182 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2183 registers that have not been assigned proper liveranges,
2184 fixes #1469504 and #1474602,
2185 (pCodeRegOptimizeRegUsage): fixed typo in comment
2187 2006-04-24 Borut Razem <borut.razem AT siol.net>
2189 * device/examples/main8051.c: deleted - it was removed from CVS
2190 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2191 after the transition to Subversion

2405 --no-peep and --peep-file <file> are used don't use default rules but
2408 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2410 * src/mcs51/gen.c (genCall): fixed bug 1457608
2412 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2431 implemented patch 1120823 Thanks to Willy De la Court (normal
2432 interrupts need an interrupt number now if they are made critical),
2433 and enabled nesting of critical functions though not for gbz80
2434 (genCritical, genEndCritical): added functions
2435 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2436 * src/z80/mappings.i: added "ei" to all mappings

2448 the left operand is shorter than the result (c* = lit-c* + int),
2450 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2453 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2455 * src/.version: increased version number to 2.5.5
2456 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2457 linking is done manually in pic16 port's _linkEdit,
2458 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2459 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2460 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2461 allocate asmop as AOP_ACC,
2462 (aopForRemat): added parameter 'bool result' in function declaration,
2463 (pic16_aopGet): return AOP_ACC when accessing WREG,
2464 (pic16_popGetTempReg): minor modification,

2475 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2476 call to allocReg, not by manually allocating a new one,
2477 (pic16_assignRegisters): now before going through the register
2478 allocating functions mark all registers as free. This eliminates some
2479 side effects resulting from peephole parser done earlier in the backbone
2481 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2531 2006-03-06 Borut Razem <borut.razem AT siol.net>
2533 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2534 made the linker quiet

2539 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2540 which dumps before the function entry point a data byte which represents
2541 the number of the local variables used by the specified function, added
2542 'xinst' for initial support for Extended Instruction Support,
2543 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2544 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2545 port->fun_prefix anymore (may change later),
2546 (genFunction, genEndFunction): do not store/restore local registers for
2547 _main (this should take care the --main-return command line option in
2549 (genOr): removed some legacy pic-port instructions,
2550 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2551 performing operations with SFR's causes data to be written more than
2552 once to each SFR. Perhaps SFRs should be handled in special cases...
2553 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2555 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2556 into account for stack starting position,

2558 --extended or -y for Extended Instruction Support,
2559 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2560 (deassignLRs): *** perhaps the most important change, old 'for' code
2561 (commented out for reference), didn't account for some registers which
2562 were left marked 'not free' after a pointer operation. The change
2563 reduces register usage a lot in some cases
2565 2006-03-04 Borut Razem <borut.razem AT siol.net>
2567 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

2599 (pic16_printIvalUnion,pic16_isUnion): NEW, handle initialized unions
2600 more correctly, fixes bug #1232186

4836 * src/SDCCglobal.h (struct options),
4838 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4839 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4840 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4841 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4842 always available in leading double underscore form. The C99 support is
4843 mostly missing, but it's a start.
4844 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4845 reserved identifier "__data".
4847 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4923 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4925 * device/lib/printf_large.c: removed inline assembly for portability and
4926 readability. Use printf_fast if speed or size are more important.
4927 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4928 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4930 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4932 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4933 prevent compiler warning
4935 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4937 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4938 moved to level 0 and declared as static. Also they are explicit
4939 placed in access bank. This was necessery because some times they
4940 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4941 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4942 optimizations. Currently only compare to unsigned char is implemented,
4943 * src/pic16/gen.c: added fReturnIdx array,
4944 * (struct resolvedIfx) is moved to gen.h and made public,
4945 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4946 * (aopForSym): added an optimization to directly store in stack of
4947 the operand of a SEND iCode,
4948 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4949 but as registers instead (AOP_REG) using the fReturnIdx array,
4950 * (pic16_freeAsmop): remove the freed register from the
4951 _G.sregsAlloc field,
4952 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4953 a compare of 'WREG',
4954 * (pic16_popGetTempRegCond): changed function prototype, now
4955 function takes also a bitVector argument v which holds the current
4956 set of registers that are allocated for stack access by aopForSym,
4957 registers allocated in aopForSym for accessing stack symbols are not
4958 any more part of the functions usedRegs field,
4959 * (genCall): some times aopOp is called for a stack variable to be
4960 send, aopForSym might perform the push, if this is true make sure
4961 that genCall doesn't push the variable twice by testing _G.resDirect,
4962 * (genFunction): changed testing for unspecified interrupt number
4963 from 256 to INTNO_UNSPEC,
4964 * modified selection scheme of frame pointer generation. Previously
4965 if function did use local registers a frame pointer was generated,
4966 now a frame pointer is generated only if function has arguments
4967 (that need PLUSW2 register access), or has stack arguments, or the
4968 compiler is not instructed to omit the frame pointer,
4969 * (genEndFunction): before restoring local registers that were saved
4970 in the function preamble, also restore the registers that *might*
4971 have been allocated for stack access,
4972 * (genRet): removed some old comments,
4973 * (genCmp, the active (RN's) version): added a call to the
4974 pic16_genCmp_special function to perform the compare with a more
4975 robust and optimized way,
4976 * (genInline): a feature has been added in inline code generation,
4977 which allows a wildcard variable substitution when writing inline
4978 assembly. Code is incomplete and experimental therefore undocumented,
4979 * (genCast): changed order of aopOp for result and right to allow
4980 aopForSym to directly load the result if possible,
4981 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4982 perform an optimized compare on some selected special occasions,
4983 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4984 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4985 generate an IVT any more,
4986 * src/pic16/main.c (pic16_optionsTable): added command line option
4988 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4989 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4991 * src/pic16/NOTES: Raphael Neider added in list of active developers
4992 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4993 jumptable_end to prevent bug #,
4994 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4995 inCond and outCond fields,
4996 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4997 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4998 turn off register spilling,
4999 * (packRegsForOneUse): synced with other ports' versions although it
5000 is not used currently,
5001 * (pic16_packRegisters): added an optimization while reading
5002 structure bitfields, some registers may be saved (malloc code is
5003 decreased by 80 bytes)
5005 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5007 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5008 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5009 this can be optimized more?
5011 2005-03-10 Raphael Neider <rneider AT web.de>
5013 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5014 genNearPointerGet): (hopefully) fixed access to bitfields via
5015 pointers (p->bitN = x; and x = p->bitN; failed)
5017 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5649 Adding support for replacing ljmps with sjmps in jumptables
5650 generated for switch statements. For now you need to set the
5651 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5652 Now 4 algorithms for mcs51 jumptable generation are used:
5653 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5654 addresses loaded pc-relative for up to 112 cases and stack-pushing
5655 target addresses loaded with offset from dptr for up to 256 cases.

5682 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5683 to call when a stack overflow occurs,
5684 * (malloc.h): added CVS Id tag,
5685 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5687 * added libc directory. The current version of LibC contains string
5688 functions, ctype functions and macros and some functions of the
5689 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5690 be extensively tested in the future. Standard disclaimer here.
5691 Library is not automatically build yet. But one can build it by
5692 invoking 'make' inside the libc directory.
5693 * added ADC library under libio. Preliminary version yet.

5703 * (pic16_storeForReturn): optimized return of 0,
5704 * (genCmp): experimental code for new genCmp which uses PIC18's
5705 special compare&skip instructions. Initial tests fail some times
5706 with variables grater than 1 byte in size, so new code is disabled,
5707 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5709 * (genCast): began a fix to optimize the casting of a bit to another
5710 bit, now assigning a bitfield to another bitfield will fail, sorry,
5711 * src/pic16/main.c: disabled the use of lr-support feature,
5712 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5715 bits with offset (case PO_GPR_BIT),
5716 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5718 * (isBankInstruction): modified to return 0 for no banking instruction,
5719 and 1 for banking instruction,
5720 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5721 caused stop processing pCodes after a inline assembly block,
5722 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5724 registers when it shouldn't,
5725 * src/pic16/ralloc.c (allocReg): add preliminary support for
5726 supporting a limited set of temporary registers,
5728 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8685 * src/pic/ralloc.h: applied patch from Slade Rich;
8686 added support for multiple code pages and multiple RAM banks on the
8687 PIC 14 port. The ASM files now no longer simply assume all the
8688 code / RAM are in the same page / bank. This means the linker can
8689 safely allocate code/RAM of separate ASM files to different pages/banks.
8690 * doc/sdccman.lyx: added Slade's tips
8691 * src/mcs51/peeph.def: fixed bug #880768

8700 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
8703 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8704 strtof is not part of C89 and isn't included with Mac OS X.
8706 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8708 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
8709 shiftL2Left2Result): fixed bug #879326
8710 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

8733 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8735 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8736 loaded with the linker search paths (-L arguments) and the libraries
8737 to be linked with the current source (-l arguments). Changes
8738 currently will affect only the pic16 port.
8739 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8740 include path the port specific paths and port specific libraries,
8741 * gplink command now contains the $3 argument,
8742 * src/pic16/device.h,
8743 * src/pic16/device.c,: structure PIC_device is made public and
8744 renamed to PIC16_device, the same for variable Pics which is renamed
8745 to Pics16. Updated all references to them.
8746 * src/pic16/glue.c (pic16glue): corrected bug with code
8747 initialization which bypassed the variable initializations block.
8749 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8750 COMPILE_FLAGS and added the --nostdinc option
8752 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8754 * device/include/mc68hc908jb8.h: Register defs for another member

8757 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8759 Documenting changes from previous commits.
8760 * configure.in (version 1.56),
8761 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8762 when generating output files to configure the pic16 library,
8763 but now I've commented it out, since gputils aren't installed in the
8764 SF compile farm, so library won't compile
8766 * device/lib/Makefile.in (version 1.56): initially I've added in
8767 target 'all' the prerequestive 'model-pic16' so it compiled the
8768 pic16 library, but now I've commented it out for the same reasons
8770 * added targets 'model-pic16' and 'objects-pic16' to compile the
8772 * added target 'port-specific-objects-pic16' to handle the
8773 generated libraries and copy them into the build/ directory
8774 * added target 'clean-intermediate-pic16' to clean intermediate
8775 files into pic16 directory
8776 * in target 'installdirs' added line to create directory pic16 in
8777 the installation path
8779 * device/include/Makefile.in (version 1.11): in target 'install'
8780 added lines to copy all header files to installation path,
8781 * in target 'installdirs' added line create directory for pic16
8782 headers in the installation path

8797 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8798 option so that it actually works. Made it specific to the z80, since
8799 the gbz80 doesn't have these kinds of I/O ports.
8801 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8803 * device/include/z180.h,

8816 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8818 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8819 changed interrupt vector table generation to only emit declared vectors.

8825 Mainly changes to support compilation of the device libraries
8826 * src/pic16/device.c: stack is allocated via symbol and not
8827 via literal number. The symbol is placed in the corresponding
8828 position of the data ram
8829 * (pic16_dump_section): relocatable and absolute uninitialized
8830 data are now emitted in sorted order to reduce section naming,
8831 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8832 weren't marked as being in the access bank,
8834 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8836 Added portion of GNU PIC Library under the directory
8837 device/include/pic16 and device/lib/pic16. These files
8838 contain the declarations of SFRs for the PIC18Fxx2 devices.
8839 The directory is initialized via configure from toplevel.
8841 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8843 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8844 the spilllocations to be compared correctly
8846 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

8869 all over. Telling LaTeX to be less strict with word spacing
8870 to better keep the right margin. Changed some notes about
8871 maintainance of the ports in section 3.2.1 - is it OK like this?
8873 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8910 UPPER for immediate operands,
8911 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8913 * src/pic16/peeph.def: all peepholes with movff are commented out,
8914 because there is a problem in the pcode peep optimizer,
8915 * src/pic16/ralloc.c: the register allocator can now reuse local

8980 directive when no overlay data exist
8981 * (picglue): modified to emit uninitialized data segment
8982 according to udata_section_name

9035 * support/valdiag/Makefile,
9036 * support/valdiag/valdiag.py,
9037 * support/valdiag/tests/*

9067 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9069 PIC16 port related changes:
9070 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9071 added variable stackPos,
9073 * gen.c: genCall, assignResultValue: added support for
9074 pushing/retrieving function parameters to/from stack,
9075 genFunction,genEndFunction: setup stack frame for the
9077 genAddrOf: will be changed according to bug 863624
9079 * added files genutils.c and genutils.h which contain gen*
9080 debugged and optimised functions extracted from gen.c
9082 * glue.c: added variable 'externs' which holds extern symbols,
9083 pic16emitRegularMap: is modified to properly handle relocatable
9084 symbols under the new scheme,
9085 pic16createInterruptVect: is modified
9086 pic16printPublics: is modified to emit 'global' assembler directives,
9087 added pic16_printExterns to print extern symbols,
9088 pic16glue: initializes stack/frame pointer in the beginning of
9089 the assembly output. Temporary hack, will be corrected later,
9090 because gplink yet does not support stack and SDCC does not
9091 yet support a type of crt0.o object to create the final binary.
9093 * Removed many lines that contain 8051 legacy code.
9094 * The code is finally placed under a 'code' directive.
9095 * Added port specific options.
9097 * _process_pragma: simplified since now we do not need *special*
9098 include file to define SFR registers. But a separate header
9099 will be needed. This will be developed later.
9100 * _pic16_parseOptions: added, parses port specific options:
9101 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9102 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9103 --preplace-udata-with=
9105 * _pic16_setDefaultOptions: modified to initialize section names,
9106 but hack is temporarly out of order since it needs improvement.
9107 * _pic16_genAssemblerPreamble: configuration words are emitted by
9108 their address instead of their name. This part is incomplete and
9109 supports only the 18Fxx2 devices. Other devices will emit an error
9110 during assembly since they do not contain the same set of config
9112 * _pic16_genIVT: is modified,
9114 * pcode.c: added definitions for some hardware registers that are needed
9116 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9117 All PCI entries are updated. Now LFSR is supported.
9118 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9119 * added pic16_newpCodeOpLit2 to support instructions with
9120 two literal arguments
9121 * pic16_pCode2str: corrected code that emits assembler instructions
9122 with two literal operands and those that have an access bit modifier
9123 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9124 this fixes a bug which caused some labels to be lost, when an
9125 assembler directive was added, i.e. banksel,
9126 * pic16_FixRegisterBanking: improved logic that causes the insertion
9128 * InlineFunction: functions that are called once, are not any more
9129 inlined. This can be a port option in the future,
9131 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9133 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9134 hold the corresponding uninitialized symbols,
9135 * pic16_allocProcessorRegister: registers have explicit marked the
9137 * pic16_allocInternalRegister: registers are explicit marked as
9139 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9140 processing list, so bit registers were lost,
9143 * ralloc.h: added field 'accessBank' and original symbol operand
9144 in register definition,
9145 * removed the field isMapped from register definition,
9147 ** Several functions have been removed from various sources:
9148 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9149 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9150 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9151 pic16_assignRelocatableRegisters
9153 ** others have been introduced:
9154 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9155 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9157 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9159 * support/scripts/inc2h.pl: changed definition of BIT_AT
9160 to emit 'sbit at' instead of 'bit at'. This was a request.
9162 PIC16 port related preliminary changes:
9163 * gen.c: prefixed function popRegFromString with
9164 pic16_ and all references to it corrected
9165 * pcode.c: all pic16_pc_* hardware registers prefixed
9166 with underscore (_),
9167 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9168 * ralloc.c: newReg(): when register is REG_SFR then
9169 set address to rIdx,
9170 pic16_allocProcessorRegister(): marks register wasUsed=0
9171 pic16_writeUsedRegs(): added a call to assign processor
9172 registers via pic16_assignFixedRegisters
9174 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9176 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9177 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9178 variables in unused register banks. Also the SSEG is placed
9179 wherever there is enough space for it, and IDATA can be anywhere
9180 in internal RAM. For now compile using -Wl-Y[stack_size].
9181 The mem file is different for this option as well, since it
9182 makes no sense of talking about DSEG lenght.
9184 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

10163 * Top header beautifications in src/pic16 directory:
10164 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
10165 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
10166 pcoderegs.h, ralloc.c, ralloc.h
10167 * main.c: added top header and GPL license notice
10168 * pcode.c: fixed the if-conditional warning
10170 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10172 * device/lib/_mullong.c: replaced int by short for gcc
10174 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10176 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10177 and JUMPTABLE iCodes properly now (worked by accident before)
10178 * src/mcs51/gen.c (leftRightUseAcc),
10179 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10180 iCode properly now. Use getSize instead of nRegs since a & b
10181 aren't part of the nRegs tally.
10183 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10185 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
10186 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
10187 before instructions that use the _STATUS register
10189 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10191 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10192 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10193 fetching of the pointer
10194 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10195 copied from genNearPointerSet()
10196 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10197 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10198 If they pop r0/r1 they must be called in the opposite order than aopOp().
10199 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10200 (resp. --stack-auto), prepared for --xstack
10202 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10204 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10206 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10208 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10209 these ports have their own __sdcc_external_start()
10211 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10213 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10214 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10215 type for bits was changed. It resulted in bit variables becoming
10216 global, which is not permitted in PIC 14 assembly output.
10218 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10220 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10222 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10224 Z80 and MCS51 linkers complaint if a public symbol is defined
10225 in more than one library module:
10229 * as/mcs51/Makefile.in
10231 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10233 A few small changes that speed up the peephole optimizer.
10237 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10239 Try to make the peephole optimizer smarter by maintaining
10240 an association between the assembly source code and the
10241 iCodes that originated them. Put this information to use
10242 with a new peephole rule condition "notVolatile" so that
10243 the rules can be aggressive yet still safe.
10248 * src/mcs51/peeph.def
10250 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10254 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10255 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10256 if the left or right operand symbols have the accuse flag set.
10258 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10260 Changed the type of the result of the ! (NOT) operator to char;
10261 previously it returned the same type as the source. This allows
10262 us to eliminate all the genFloatNot functions (all of its target
10263 implementations were very buggy) since !float can use the same
10266 * src/SDCCicode.c (ast2iCode): ! returns char
10267 * src/mcs51/gen.c (genNot, genNotFloat),
10268 * src/ds390/gen.c (genNot, genNotFloat),
10269 * src/z80/gen.c (genNot, genNotFloat),
10270 * src/pic/gen.c (genNot, genNotFloat),
10271 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10275 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10276 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10277 during interrupts. Ensure WSAVE is located at a shared bank address.
10278 2. Fixed page selection in some places
10279 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10280 the registers name strings.
10281 4. Fixed "signed / unsigned compare" compiler warnings.
10282 5. The PIC port manages its own allocation of the general purpose
10283 registers, but makes no attempt to reuse them. As a result when
10284 compiling it soon runs out of general purpose registers. Some
10285 additional code was added to the files pcode.c and device.c to walk
10286 through the function call tree and rename the registers so that they
10296 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10297 genPlus() & genMinus() when the result is the same as left or right
10299 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10301 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
10303 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10305 Made bitfield a distinct type from bit so that bitfields
10306 convert as per ANSI C and bits retain their traditional
10307 boolean style behaviour. Implemented bitfield support in
10315 * src/ds390/gen.c: bit v bitfield split
10316 * src/z80/gen.c: New support for bitfields
10317 * support/regression/tests/bitfields.c: reenabled z80,
10320 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10322 Rules 246.x, 247.x relate to bitfields, the others speed up
10323 access to xdata mapped I/O devices.
10325 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10327 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10329 Cleaned up genPackBits and genUnpackBits and added two helper
10330 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10331 for literal assignments in genPackBits (thanks to Frieder for
10337 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10339 Fixed bug #748310 (pointer to function type mishandled when the
10340 function name is omitted). Also fixed a SIGSEGV when a function
10341 attribute (reentrant, etc) is used on a non-function or on a
10342 function but misplaced before the parameter list.
10344 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10346 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10347 * support/Util/SDCCerr.h,
10348 * support/Util/SDCCerr.c: Added func attr misuse error msg
10350 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10352 Fixed bug #787649 by anonymous
10353 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10354 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10356 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10358 Fixed numerous bitfield problems.
10360 * src/SDCC.y: More bitfield related error checking
10362 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
10363 * support/Util/SDCCerr.h,
10364 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
10365 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10366 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10367 * support/regression/tests/bitfields.c: tests added
10369 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10371 Made the constant following the "interrupt" keyword optional. If
10372 omitted, the function will not automatically be given an entry
10373 in the interrupt vector table (similar to #pragma NOIV, but
10374 less syntacticly kludgy). The interrupt number is also now
10375 range checked. Also fixed a bug in the high order bit example

10383 * support/Util/SDCCerr.h
10386 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10389 * src/SDCCicode.c (operandOperation): rewritten some ops
10390 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10391 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10393 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10394 be re-activated by defining REDUCE_LITERALS)
10395 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10396 unsigned, but are signed by default
10397 * src/SDCCval.c (constVal): rearranged
10398 * src/SDCCval.c (valMod): preliminary fix
10399 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10437 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
10439 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10440 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10441 constants are unsigned; added recognition of "u" flag for unsigned
10442 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10443 * src/SDCCval.c (valDiv, valMod): fixed signdness
10444 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10445 signedness of modulo, left and right shift

10852 the regression tests I'm not brave enough to enable 245.b, 245.c
10853 * doc/sdccman.lyx: added latex preamble for hyperref package.
10854 Using pdflatex this will give you a hyperlinked pdf file with

10896 it can be defined with CFLAGS when running configure
10897 * src/SDCCmain.c: fixed compiling + linking with object files
10899 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10904 * src/SDCCmain.c: linkOptions is changed to set *,
10905 added if/endif conditional macros to remove options help
10906 messages from optionsTable when a port is not configured, added
10907 support for the PIc16 port in the ports table, when executing
10908 the compiler with no port specified on command line, a default
10909 port is selected with the new macro DEFAULT_PORT which is
10910 defined in port.h, in setDefaultOptions() linkOptions is removed
10911 from initialization assignment, since now it is a set,
10912 parseCmdLine uses setParseWithComma for linkOptions, in
10913 linkEdit() linkOptions are accessed with new function indexSet()
10914 which returns the i'th item of a set variable. See SDCCset.c, in
10915 linkEdit() when calling buildCmdLine(), added linkOptions as
10916 last argument. Now users can pass arguments to gplink via the
10917 -Wl option, main() uses pic16glue() to glue up pic16 programs
10918 * src/SDCCpeeph.c: various changes to support pic16
10919 * src/SDCCset.c: added function void *indexSet(set *, int) to

10929 * src/pic16/glue.c: commented out some error producing lines
10930 * src/pic16/main.c: __config directives are commented out to stop
10931 gpasm complaining and test the linkage with gplink, _linkCmd and
10932 _asmCmd changed to be more gplink and gpasm friendly
10933 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10934 produced an error when parsed, peep rule 12 is added to utilize
10935 movff, but it is commented out since the pCode does not support
10936 yet a command with 2 address arguments
10938 2003-05-18 <johan AT balder>
10940 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10967 2003-05-11 Borut Razem <borut.razem AT siol.net>
10969 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10970 the path of bin directory, so that PATH is the only env. variable, which has to be set

11992 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11993 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11995 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11996 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11998 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11999 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12001 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12003 * in /sdcc/as/mcs51/ changed these files in order to create an
12004 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12005 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12006 following files to include the previous two files: aslink.dsp,
12007 Makefile.aslink, Makefile.bcc, and Makefile.in.
12009 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12010 .adb instead of .cdb
12012 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12014 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12015 value from option --iram-size.
12017 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12019 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12022 2002-09-18 <wiml AT hhhh.org>
12024 * SDCClrange.h: exposed setFromRange() and setToRange()
12025 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12026 packRegsForAccUse() (bug 542397)
12027 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12028 multiple times and emitting the fetch operations more than once
12029 added aopGetUsesAcc() function to allow binary operators to
12030 fetch their operands in the correct order; made genMinus() emit
12031 compact code for X = LITERAL - Y
12033 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12034 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12035 sprintf() in line 1267.
12037 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12038 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12041 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12042 Changes to aslink (All the changes are marked with 'JCF'):
12044 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12047 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12048 area BSEG. Also moves, if possible, the DATA area down into the internal
12049 ram so more space is available.
12051 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12054 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12055 not bytes. Function summary() which creates a memory usage summary
12056 file with extension .mem. Reports of overlaping stack and small stack
12057 size. If the space for the stack is less than 16 bytes aslink trows a
12060 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12061 the 8051. Option 'y' for memory summary output file.
12063 Changes to sdcc (All the changes are marked with 'JCF'):
12065 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12067 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12068 overlaying area for it (uses RegBankUsed[4]).
12070 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12071 bank zero as used by default. By default aslink locates the stack
12072 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12073 the creation of the .mem file. Delegates the allocation of data area
12074 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12075 the begining of the stack area to aslink.
12077 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12078 glue() in SDCCglue.c creates an area for it.
12080 2002-09-03 Borut Razem <borut.razem AT siol.net>
12081 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12082 sdcc/src/pic/glue.c:
12083 introduced atexit() handler for teporay files removal in case of
12084 errors, assertions, ...
12086 2002-08-29 Borut Razem <borut.razem AT siol.net>
12087 * sdcc/support/cpp2/auto-host_vc_in.h:
12088 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12089 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12090 Maybe there is a similar problem with BORLANDC? It should be checked!
12092 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12093 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12094 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12095 was not executed, and the compiler (cl) launched a warning:
12096 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12098 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12099 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12101 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12102 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12104 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12105 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12106 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12107 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12108 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12109 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12110 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12111 - added Release configuration in VS projects
12112 - review of compiler an linker options
12113 - VC .exe files are generated in bin_vc directory, not to interfere
12114 with binaries generated from other projects (cygwin, mingw, bcc ...)
12116 * sdcc/src/yacc.dsp: added
12118 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12119 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12120 and insert the version number definitions from .version
12122 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12124 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12125 added - genarate auto-host.h using auto-host_vc_in.h as template
12128 removed from CVS, generated automatically
12130 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12131 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12133 2002-08-11 Borut Razem <borut.razem AT siol.net>
12134 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12136 2002-08-10 Borut Razem <borut.razem AT siol.net>
12137 * src/SDCCmain.c (main):
12138 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12139 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12140 The consequence was that some temporary files were not removed.
12143 unification of code in functions tempfilename() and tempfile():
12144 function tempnam() is defined in Visual Studio 6.0 and .NET
12146 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12148 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12149 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12150 - removed compiler command line option /WX: Treats all warnings as errors
12151 - update a list of source files, included into the project
12153 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12154 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12155 changed project type to Generic Project so that can be correcly converted to VS.NET project
12157 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12159 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12161 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12163 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12164 added return 0 statements after assert() to make compiler happy
12166 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12167 added newline in the def file to keep MSC compiler satisfied
12169 * sdcc/src/z80/gen.c:
12170 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12171 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12172 - solved MSC error in function aopDump()
12174 * sdcc_vc.h: define PREFIX as "\\sdcc"
12176 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12177 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12180 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12181 - Rewrote the register banking algorithm.
12182 - Added pCode live-range analysis to registers (for now, only non-used and
12183 singly-used registers optimized away)
12185 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12187 * 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.

12212 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12214 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12216 2002-03-28 Johan Knol <johan AT balder>
12218 * src/SDCCval.c: fixed bug #532436
12220 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12222 Added "char *Processor" field to the port structure.
12225 Added -p option. Allows port dependent processor to be specified.
12228 Initialized the new field char *Processor field to NULL in all ports
12231 Compiler generated registers for interrupt context saving
12232 were not getting allocated.
12234 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12237 Fixed left shift. Will promote the left side of a left shift
12238 if a) left shifting more than size of operand or b) when assigned
12239 to something size > size of left side
12241 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12245 analysis is restructured. ...
12247 * src/pic/device.h:
12250 * src/pic/device.c:
12251 Added. device.c is a PIC port hack to accomodate variations
12254 2002-03-13 Michael Hope <michaelh AT vroom>
12256 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12258 2002-03-04 johanknol <johanknol AT manik>
12260 * /src/SDCCval.c: fixed

12349 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12351 * sdcc/src/SDCCloop.c:
12352 Previous fix was not good. basic blocks that have "break" or "return" are
12353 not really partof a loop , but live ranges used in these blocks should
12354 be live thru the entire loop, so set partOfLoop but don't add them to
12357 2002-02-21 <johan AT FRIJA>
12359 * src/SDCCcse.c: fixed bug #514308
12361 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
12364 Fixed BUG #519583. If a conditional block ended in a return/break
12365 statement inside a loop, it was not being considered part of the loop.
12367 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12369 2002-02-10 Karl Bongers <karl AT turbobit.com>
