3022 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3023 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3025 One basic decision: e.g. src/clean.mk includes further files. In order
3026 to make this work there are two solutions:
3027 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3028 run configure on them. This way they can use
3029 'include $(srcdir)/port-clean.mk'
3030 - always include clean.mk by the Makefile at the same level. To avoid
3031 that `make clean` tries to include and build Makefile.dep the
3032 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3033 implemented, because now even `make uninstall` doesn't create
3034 Makefile.in. clean.mk could be eliminated by pasting it in
3037 * debugger/mcs51/Makefile.in: build own objects from library sources
3038 (SLIB, SDCC) in current directory
3040 * configure, configure.in: renamed --disable-device-lib-build in

3303 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3305 * src/mcs51/gen.c (genCall): fixed bug 1457608
3307 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3325 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3326 implemented patch 1120823 Thanks to Willy De la Court (normal
3327 interrupts need an interrupt number now if they are made critical),
3328 and enabled nesting of critical functions though not for gbz80
3329 (genCritical, genEndCritical): added functions
3330 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3331 * src/z80/mappings.i: added "ei" to all mappings

3340 2006-03-16 Raphael Neider <rneider AT web.de>
3342 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3343 the left operand is shorter than the result (c* = lit-c* + int),
3345 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3348 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3350 * src/.version: increased version number to 2.5.5
3351 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3352 linking is done manually in pic16 port's _linkEdit,
3353 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3354 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3355 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3356 allocate asmop as AOP_ACC,
3357 (aopForRemat): added parameter 'bool result' in function declaration,
3358 (pic16_aopGet): return AOP_ACC when accessing WREG,
3359 (pic16_popGetTempReg): minor modification,

3370 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3371 call to allocReg, not by manually allocating a new one,
3372 (pic16_assignRegisters): now before going through the register
3373 allocating functions mark all registers as free. This eliminates some
3374 side effects resulting from peephole parser done earlier in the backbone
3376 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3378 * src/SDCCicode.c (geniCodeLogic),

3424 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3426 2006-03-06 Borut Razem <borut.razem AT siol.net>
3428 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3429 made the linker quiet
3431 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3433 * src/pic16/gen.c (genPcall): fixed bug #1443644
3434 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3435 which dumps before the function entry point a data byte which represents
3436 the number of the local variables used by the specified function, added
3437 'xinst' for initial support for Extended Instruction Support,
3438 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3439 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3440 port->fun_prefix anymore (may change later),
3441 (genFunction, genEndFunction): do not store/restore local registers for
3442 _main (this should take care the --main-return command line option in
3444 (genOr): removed some legacy pic-port instructions,
3445 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3446 performing operations with SFR's causes data to be written more than
3447 once to each SFR. Perhaps SFRs should be handled in special cases...
3448 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3450 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3451 into account for stack starting position,
3452 (struct OPTIONS pic16_optionsTable): added command line argument
3453 --extended or -y for Extended Instruction Support,
3454 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3455 (deassignLRs): *** perhaps the most important change, old 'for' code
3456 (commented out for reference), didn't account for some registers which
3457 were left marked 'not free' after a pointer operation. The change
3458 reduces register usage a lot in some cases
3460 2006-03-04 Borut Razem <borut.razem AT siol.net>

5733 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5734 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5735 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5736 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5737 always available in leading double underscore form. The C99 support is
5738 mostly missing, but it's a start.
5739 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5740 reserved identifier "__data".

5818 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5820 * device/lib/printf_large.c: removed inline assembly for portability and
5821 readability. Use printf_fast if speed or size are more important.
5822 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5823 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5825 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5827 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5828 prevent compiler warning
5830 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5832 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5833 moved to level 0 and declared as static. Also they are explicit
5834 placed in access bank. This was necessery because some times they
5835 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5836 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5837 optimizations. Currently only compare to unsigned char is implemented,
5838 * src/pic16/gen.c: added fReturnIdx array,
5839 * (struct resolvedIfx) is moved to gen.h and made public,
5840 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5841 * (aopForSym): added an optimization to directly store in stack of
5842 the operand of a SEND iCode,
5843 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5844 but as registers instead (AOP_REG) using the fReturnIdx array,
5845 * (pic16_freeAsmop): remove the freed register from the
5846 _G.sregsAlloc field,
5847 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5848 a compare of 'WREG',
5849 * (pic16_popGetTempRegCond): changed function prototype, now
5850 function takes also a bitVector argument v which holds the current
5851 set of registers that are allocated for stack access by aopForSym,
5852 registers allocated in aopForSym for accessing stack symbols are not
5853 any more part of the functions usedRegs field,
5854 * (genCall): some times aopOp is called for a stack variable to be
5855 send, aopForSym might perform the push, if this is true make sure
5856 that genCall doesn't push the variable twice by testing _G.resDirect,
5857 * (genFunction): changed testing for unspecified interrupt number
5858 from 256 to INTNO_UNSPEC,
5859 * modified selection scheme of frame pointer generation. Previously
5860 if function did use local registers a frame pointer was generated,
5861 now a frame pointer is generated only if function has arguments
5862 (that need PLUSW2 register access), or has stack arguments, or the
5863 compiler is not instructed to omit the frame pointer,
5864 * (genEndFunction): before restoring local registers that were saved
5865 in the function preamble, also restore the registers that *might*
5866 have been allocated for stack access,
5867 * (genRet): removed some old comments,
5868 * (genCmp, the active (RN's) version): added a call to the
5869 pic16_genCmp_special function to perform the compare with a more
5870 robust and optimized way,
5871 * (genInline): a feature has been added in inline code generation,
5872 which allows a wildcard variable substitution when writing inline
5873 assembly. Code is incomplete and experimental therefore undocumented,
5874 * (genCast): changed order of aopOp for result and right to allow
5875 aopForSym to directly load the result if possible,
5876 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5877 perform an optimized compare on some selected special occasions,
5878 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5879 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5880 generate an IVT any more,
5881 * src/pic16/main.c (pic16_optionsTable): added command line option
5883 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5884 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5886 * src/pic16/NOTES: Raphael Neider added in list of active developers
5887 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5888 jumptable_end to prevent bug #,
5889 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5890 inCond and outCond fields,
5891 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5892 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5893 turn off register spilling,
5894 * (packRegsForOneUse): synced with other ports' versions although it
5895 is not used currently,
5896 * (pic16_packRegisters): added an optimization while reading
5897 structure bitfields, some registers may be saved (malloc code is
5898 decreased by 80 bytes)
5900 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5902 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5903 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5904 this can be optimized more?
5906 2005-03-10 Raphael Neider <rneider AT web.de>
5908 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5909 genNearPointerGet): (hopefully) fixed access to bitfields via
5910 pointers (p->bitN = x; and x = p->bitN; failed)

5956 to keep the correct label reference count when adding/removing references
5957 to labels. A peephole file using this is appended to patch #1144962.

6544 Adding support for replacing ljmps with sjmps in jumptables
6545 generated for switch statements. For now you need to set the
6546 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6547 Now 4 algorithms for mcs51 jumptable generation are used:
6548 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6549 addresses loaded pc-relative for up to 112 cases and stack-pushing
6550 target addresses loaded with offset from dptr for up to 256 cases.

6580 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6582 * added libc directory. The current version of LibC contains string
6583 functions, ctype functions and macros and some functions of the
6584 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6585 be extensively tested in the future. Standard disclaimer here.
6586 Library is not automatically build yet. But one can build it by
6587 invoking 'make' inside the libc directory.
6588 * added ADC library under libio. Preliminary version yet.

6598 * (pic16_storeForReturn): optimized return of 0,
6599 * (genCmp): experimental code for new genCmp which uses PIC18's
6600 special compare&skip instructions. Initial tests fail some times
6601 with variables grater than 1 byte in size, so new code is disabled,
6602 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6604 * (genCast): began a fix to optimize the casting of a bit to another
6605 bit, now assigning a bitfield to another bitfield will fail, sorry,
6606 * src/pic16/main.c: disabled the use of lr-support feature,
6607 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6614 and 1 for banking instruction,
6615 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6616 caused stop processing pCodes after a inline assembly block,
6617 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6619 registers when it shouldn't,
6620 * src/pic16/ralloc.c (allocReg): add preliminary support for
6621 supporting a limited set of temporary registers,
6623 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6625 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

6629 (genFunction): optimize RECEIVE iCodes in reentrant functions
6631 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9519 * src/SDCCast.c (addCast): added promotion to int
9520 (decorateType): updated call to upCast()
9521 * src/SDCCicode.c (geniCodeLeftShift): removed call to
9522 usualUnaryConversions()
9524 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
9526 * support/regression/tests/literalop.c (mulWrapper): Added a
9527 wrapper to remove integer overflow warnings.
9529 * support/regression/tests/float_trans.c: Made work on host.
9531 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
9534 * support/regression/generate-cases.py (main): Changed from inline
9537 * doc/Makefile (install): Changed to depth first to get rid of
9538 missing directory install warning.
9540 * as/Makefile (install-doc): Made work on Mac.
9542 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
9544 * src/SDCCast.c: added an additional type flow in decorateType() of
9545 opposite direction, see feature request #860006; it's enabled at runtime
9546 by setting the environment variable SDCC_NEWTYPEFLOW
9547 * src/SDCCast.h: changed prototype of decorateType()
9548 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
9549 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
9550 'char' to 'int' can be omitted, if both operands are 'unsigned char';
9551 see feature request #877103
9552 * src/SDCCval.c: updated call of decorateType()
9553 (valBitwise): fixed bug #882876
9554 (valMinus): added promotion
9555 (valLogicAndOr): result is unsigned
9556 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
9557 * src/SDCCsymt.c (computeType),
9558 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
9559 must not cause an unsigned operation
9560 * src/pic/glue (pic14emitRegularMap),

9580 * src/pic/ralloc.h: applied patch from Slade Rich;
9581 added support for multiple code pages and multiple RAM banks on the
9582 PIC 14 port. The ASM files now no longer simply assume all the
9583 code / RAM are in the same page / bank. This means the linker can
9584 safely allocate code/RAM of separate ASM files to different pages/banks.
9585 * doc/sdccman.lyx: added Slade's tips
9586 * src/mcs51/peeph.def: fixed bug #880768

9598 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9599 strtof is not part of C89 and isn't included with Mac OS X.
9601 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9603 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

9628 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9630 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9631 loaded with the linker search paths (-L arguments) and the libraries
9632 to be linked with the current source (-l arguments). Changes
9633 currently will affect only the pic16 port.
9634 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9635 include path the port specific paths and port specific libraries,
9636 * gplink command now contains the $3 argument,
9637 * src/pic16/device.h,
9638 * src/pic16/device.c,: structure PIC_device is made public and
9639 renamed to PIC16_device, the same for variable Pics which is renamed

9654 Documenting changes from previous commits.
9655 * configure.in (version 1.56),
9656 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9657 when generating output files to configure the pic16 library,
9658 but now I've commented it out, since gputils aren't installed in the
9659 SF compile farm, so library won't compile
9661 * device/lib/Makefile.in (version 1.56): initially I've added in
9662 target 'all' the prerequestive 'model-pic16' so it compiled the
9663 pic16 library, but now I've commented it out for the same reasons
9665 * added targets 'model-pic16' and 'objects-pic16' to compile the
9667 * added target 'port-specific-objects-pic16' to handle the
9668 generated libraries and copy them into the build/ directory
9669 * added target 'clean-intermediate-pic16' to clean intermediate
9670 files into pic16 directory
9671 * in target 'installdirs' added line to create directory pic16 in
9672 the installation path
9674 * device/include/Makefile.in (version 1.11): in target 'install'
9675 added lines to copy all header files to installation path,
9676 * in target 'installdirs' added line create directory for pic16
9677 headers in the installation path

9692 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9693 option so that it actually works. Made it specific to the z80, since
9694 the gbz80 doesn't have these kinds of I/O ports.
9696 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9698 * device/include/z180.h,

9720 Mainly changes to support compilation of the device libraries
9721 * src/pic16/device.c: stack is allocated via symbol and not
9722 via literal number. The symbol is placed in the corresponding
9723 position of the data ram
9724 * (pic16_dump_section): relocatable and absolute uninitialized
9725 data are now emitted in sorted order to reduce section naming,
9726 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9727 weren't marked as being in the access bank,
9729 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9731 Added portion of GNU PIC Library under the directory
9732 device/include/pic16 and device/lib/pic16. These files
9733 contain the declarations of SFRs for the PIC18Fxx2 devices.
9734 The directory is initialized via configure from toplevel.

9764 all over. Telling LaTeX to be less strict with word spacing
9765 to better keep the right margin. Changed some notes about
9766 maintainance of the ports in section 3.2.1 - is it OK like this?
9768 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9808 * src/pic16/peeph.def: all peepholes with movff are commented out,
9809 because there is a problem in the pcode peep optimizer,
9810 * src/pic16/ralloc.c: the register allocator can now reuse local

9949 Bug reported from Jesus Calvino-Fraga
9951 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9953 * sdcc.spec: updated
9954 * device/include/Makefile.in: don't install CVS directories
9955 * device/lib/Makefile.in: added removal of CVS directories after install
9956 * doc/Makefile: fixed install, added local_icons
9957 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9958 * src/mcs51/gen.c (genRightShift): fixed bug #870788

9962 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9964 PIC16 port related changes:
9965 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9966 added variable stackPos,
9968 * gen.c: genCall, assignResultValue: added support for
9969 pushing/retrieving function parameters to/from stack,
9970 genFunction,genEndFunction: setup stack frame for the
9972 genAddrOf: will be changed according to bug 863624
9974 * added files genutils.c and genutils.h which contain gen*
9975 debugged and optimised functions extracted from gen.c
9977 * glue.c: added variable 'externs' which holds extern symbols,
9978 pic16emitRegularMap: is modified to properly handle relocatable
9979 symbols under the new scheme,
9980 pic16createInterruptVect: is modified
9981 pic16printPublics: is modified to emit 'global' assembler directives,
9982 added pic16_printExterns to print extern symbols,
9983 pic16glue: initializes stack/frame pointer in the beginning of
9984 the assembly output. Temporary hack, will be corrected later,
9985 because gplink yet does not support stack and SDCC does not
9986 yet support a type of crt0.o object to create the final binary.
9988 * Removed many lines that contain 8051 legacy code.
9989 * The code is finally placed under a 'code' directive.
9990 * Added port specific options.
9992 * _process_pragma: simplified since now we do not need *special*
9993 include file to define SFR registers. But a separate header
9994 will be needed. This will be developed later.
9995 * _pic16_parseOptions: added, parses port specific options:
9996 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9997 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9998 --preplace-udata-with=
10000 * _pic16_setDefaultOptions: modified to initialize section names,
10001 but hack is temporarly out of order since it needs improvement.
10002 * _pic16_genAssemblerPreamble: configuration words are emitted by
10003 their address instead of their name. This part is incomplete and
10004 supports only the 18Fxx2 devices. Other devices will emit an error
10005 during assembly since they do not contain the same set of config
10007 * _pic16_genIVT: is modified,
10009 * pcode.c: added definitions for some hardware registers that are needed
10011 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10012 All PCI entries are updated. Now LFSR is supported.
10013 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10014 * added pic16_newpCodeOpLit2 to support instructions with
10015 two literal arguments
10016 * pic16_pCode2str: corrected code that emits assembler instructions
10017 with two literal operands and those that have an access bit modifier
10018 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10019 this fixes a bug which caused some labels to be lost, when an
10020 assembler directive was added, i.e. banksel,
10021 * pic16_FixRegisterBanking: improved logic that causes the insertion
10023 * InlineFunction: functions that are called once, are not any more
10024 inlined. This can be a port option in the future,
10026 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10028 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10029 hold the corresponding uninitialized symbols,
10030 * pic16_allocProcessorRegister: registers have explicit marked the
10032 * pic16_allocInternalRegister: registers are explicit marked as
10034 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10035 processing list, so bit registers were lost,
10038 * ralloc.h: added field 'accessBank' and original symbol operand
10039 in register definition,
10040 * removed the field isMapped from register definition,
10042 ** Several functions have been removed from various sources:
10043 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10044 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10045 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10046 pic16_assignRelocatableRegisters
10048 ** others have been introduced:
10049 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10050 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10052 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10054 * support/scripts/inc2h.pl: changed definition of BIT_AT
10055 to emit 'sbit at' instead of 'bit at'. This was a request.
10057 PIC16 port related preliminary changes:
10058 * gen.c: prefixed function popRegFromString with
10059 pic16_ and all references to it corrected
10060 * pcode.c: all pic16_pc_* hardware registers prefixed
10061 with underscore (_),
10062 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10063 * ralloc.c: newReg(): when register is REG_SFR then
10064 set address to rIdx,
10065 pic16_allocProcessorRegister(): marks register wasUsed=0
10066 pic16_writeUsedRegs(): added a call to assign processor
10067 registers via pic16_assignFixedRegisters
10069 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10071 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10072 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10073 variables in unused register banks. Also the SSEG is placed
10074 wherever there is enough space for it, and IDATA can be anywhere
10075 in internal RAM. For now compile using -Wl-Y[stack_size].
10076 The mem file is different for this option as well, since it
10077 makes no sense of talking about DSEG lenght.
10079 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10081 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10082 in certain cases, e.g. when ROM assignment, patch provided
10083 from Albert den Haan.

10326 * src/SDCCast.c (decorateType): disabled a transformation I added in
10327 revision 1.188 (access to fields of a structure at an absolute address);
10328 it breaks with bitfields, extern declarations, and gcse analysis.
10329 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10330 could be assigned through a pointer, so don't complain.

10953 correct when using both critical and reentrant/stack-auto.
10954 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
10955 size (can be triggered in error if sloc is shared between
10956 different sized objects)
10957 * device/include/float.h: fixed macros to explicitly use
10958 unsigned long where needed
10960 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10970 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10971 support for standard C idiom of memory mapped variables; for
10972 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10973 to xdata int at 0x1234 tempvar = 1.
10974 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

10991 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10993 Fixed bug #621531 (const & volatile confusion in the type chain).
10994 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10995 refer to the const or volatile state of the pointer itself.

11008 * support/regression/tests/const.c
11010 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11012 When checking for duplicated modules, use absolute paths

11065 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11067 * device/lib/_mullong.c: replaced int by short for gcc
11069 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11071 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11072 and JUMPTABLE iCodes properly now (worked by accident before)
11073 * src/mcs51/gen.c (leftRightUseAcc),
11074 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11075 iCode properly now. Use getSize instead of nRegs since a & b
11076 aren't part of the nRegs tally.
11078 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11080 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11090 copied from genNearPointerSet()
11091 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11092 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11093 If they pop r0/r1 they must be called in the opposite order than aopOp().
11094 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11095 (resp. --stack-auto), prepared for --xstack
11097 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11099 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11101 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11106 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11108 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11109 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11110 type for bits was changed. It resulted in bit variables becoming
11111 global, which is not permitted in PIC 14 assembly output.
11113 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11115 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11117 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11119 Z80 and MCS51 linkers complaint if a public symbol is defined
11120 in more than one library module:

11126 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11128 A few small changes that speed up the peephole optimizer.
11132 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11134 Try to make the peephole optimizer smarter by maintaining
11135 an association between the assembly source code and the
11136 iCodes that originated them. Put this information to use
11137 with a new peephole rule condition "notVolatile" so that
11138 the rules can be aggressive yet still safe.
11143 * src/mcs51/peeph.def
11145 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11149 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11150 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11151 if the left or right operand symbols have the accuse flag set.
11153 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11155 Changed the type of the result of the ! (NOT) operator to char;
11156 previously it returned the same type as the source. This allows
11157 us to eliminate all the genFloatNot functions (all of its target
11158 implementations were very buggy) since !float can use the same
11161 * src/SDCCicode.c (ast2iCode): ! returns char
11162 * src/mcs51/gen.c (genNot, genNotFloat),
11163 * src/ds390/gen.c (genNot, genNotFloat),
11164 * src/z80/gen.c (genNot, genNotFloat),
11165 * src/pic/gen.c (genNot, genNotFloat),
11166 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11170 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11171 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11172 during interrupts. Ensure WSAVE is located at a shared bank address.
11173 2. Fixed page selection in some places
11174 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11175 the registers name strings.
11176 4. Fixed "signed / unsigned compare" compiler warnings.
11177 5. The PIC port manages its own allocation of the general purpose
11178 registers, but makes no attempt to reuse them. As a result when
11179 compiling it soon runs out of general purpose registers. Some
11180 additional code was added to the files pcode.c and device.c to walk
11181 through the function call tree and rename the registers so that they
11191 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11192 genPlus() & genMinus() when the result is the same as left or right
11194 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11198 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11200 Made bitfield a distinct type from bit so that bitfields
11201 convert as per ANSI C and bits retain their traditional
11202 boolean style behaviour. Implemented bitfield support in
11210 * src/ds390/gen.c: bit v bitfield split
11211 * src/z80/gen.c: New support for bitfields
11212 * support/regression/tests/bitfields.c: reenabled z80,
11215 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11217 Rules 246.x, 247.x relate to bitfields, the others speed up
11218 access to xdata mapped I/O devices.
11220 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11222 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11224 Cleaned up genPackBits and genUnpackBits and added two helper
11225 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11226 for literal assignments in genPackBits (thanks to Frieder for
11232 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11234 Fixed bug #748310 (pointer to function type mishandled when the
11235 function name is omitted). Also fixed a SIGSEGV when a function
11236 attribute (reentrant, etc) is used on a non-function or on a
11237 function but misplaced before the parameter list.
11239 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11241 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11242 * support/Util/SDCCerr.h,
11243 * support/Util/SDCCerr.c: Added func attr misuse error msg
11245 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11247 Fixed bug #787649 by anonymous
11248 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11249 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11251 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11253 Fixed numerous bitfield problems.
11255 * src/SDCC.y: More bitfield related error checking

11264 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11266 Made the constant following the "interrupt" keyword optional. If
11267 omitted, the function will not automatically be given an entry
11268 in the interrupt vector table (similar to #pragma NOIV, but
11269 less syntacticly kludgy). The interrupt number is also now
11270 range checked. Also fixed a bug in the high order bit example
11277 * support/Util/SDCCerr.c
11278 * support/Util/SDCCerr.h
11281 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11284 * src/SDCCicode.c (operandOperation): rewritten some ops
11285 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11286 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11288 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11289 be re-activated by defining REDUCE_LITERALS)
11290 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11291 unsigned, but are signed by default
11292 * src/SDCCval.c (constVal): rearranged
11293 * src/SDCCval.c (valMod): preliminary fix
11294 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11332 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
11334 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11335 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11336 constants are unsigned; added recognition of "u" flag for unsigned
11337 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11338 * src/SDCCval.c (valDiv, valMod): fixed signdness
11339 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11340 signedness of modulo, left and right shift

11801 messages from optionsTable when a port is not configured, added
11802 support for the PIc16 port in the ports table, when executing
11803 the compiler with no port specified on command line, a default
11804 port is selected with the new macro DEFAULT_PORT which is
11805 defined in port.h, in setDefaultOptions() linkOptions is removed
11806 from initialization assignment, since now it is a set,
11807 parseCmdLine uses setParseWithComma for linkOptions, in
11808 linkEdit() linkOptions are accessed with new function indexSet()
11809 which returns the i'th item of a set variable. See SDCCset.c, in
11810 linkEdit() when calling buildCmdLine(), added linkOptions as
11811 last argument. Now users can pass arguments to gplink via the
11812 -Wl option, main() uses pic16glue() to glue up pic16 programs

11826 gpasm complaining and test the linkage with gplink, _linkCmd and
11827 _asmCmd changed to be more gplink and gpasm friendly
11828 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11829 produced an error when parsed, peep rule 12 is added to utilize
11830 movff, but it is commented out since the pCode does not support
11831 yet a command with 2 address arguments
11833 2003-05-18 <johan AT balder>

12810 2003-01-12 Bernhard Held <bernhard AT bernhardheld.de>
12812 * src/SDCCmain.c (main): port->finaliseOptions() moved for z80 linking
12813 * src/SDCCutil.c (join): ugly bug: missing '\0'

12857 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
12858 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12859 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings

12868 2003-01-06 <johan AT balder>
12870 * src/SDCCicode.c: fixed array add
12872 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12873 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12874 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12876 2003-01-04 <johan AT balder>

12880 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12881 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12883 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12884 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12885 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12887 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12888 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12890 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12891 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12893 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12894 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12896 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12898 * in /sdcc/as/mcs51/ changed these files in order to create an
12899 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12900 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12901 following files to include the previous two files: aslink.dsp,
12902 Makefile.aslink, Makefile.bcc, and Makefile.in.
12904 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12905 .adb instead of .cdb
12907 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12909 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12910 value from option --iram-size.
12912 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12914 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12917 2002-09-18 <wiml AT hhhh.org>
12919 * SDCClrange.h: exposed setFromRange() and setToRange()
12920 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12921 packRegsForAccUse() (bug 542397)
12922 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12923 multiple times and emitting the fetch operations more than once
12924 added aopGetUsesAcc() function to allow binary operators to
12925 fetch their operands in the correct order; made genMinus() emit
12926 compact code for X = LITERAL - Y
12928 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12929 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12930 sprintf() in line 1267.
12932 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12933 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12936 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12937 Changes to aslink (All the changes are marked with 'JCF'):
12939 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12942 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12943 area BSEG. Also moves, if possible, the DATA area down into the internal
12944 ram so more space is available.
12946 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12949 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12950 not bytes. Function summary() which creates a memory usage summary
12951 file with extension .mem. Reports of overlaping stack and small stack
12952 size. If the space for the stack is less than 16 bytes aslink trows a
12955 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12956 the 8051. Option 'y' for memory summary output file.
12958 Changes to sdcc (All the changes are marked with 'JCF'):
12960 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12962 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12963 overlaying area for it (uses RegBankUsed[4]).
12965 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12966 bank zero as used by default. By default aslink locates the stack
12967 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12968 the creation of the .mem file. Delegates the allocation of data area
12969 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12970 the begining of the stack area to aslink.
12972 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12973 glue() in SDCCglue.c creates an area for it.
12975 2002-09-03 Borut Razem <borut.razem AT siol.net>
12976 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12977 sdcc/src/pic/glue.c:
12978 introduced atexit() handler for teporay files removal in case of
12979 errors, assertions, ...
12981 2002-08-29 Borut Razem <borut.razem AT siol.net>
12982 * sdcc/support/cpp2/auto-host_vc_in.h:
12983 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12984 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12985 Maybe there is a similar problem with BORLANDC? It should be checked!
12987 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12988 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12989 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12990 was not executed, and the compiler (cl) launched a warning:
12991 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12993 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12994 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12996 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12997 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12999 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13000 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13001 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13002 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13003 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13004 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13005 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13006 - added Release configuration in VS projects
13007 - review of compiler an linker options
13008 - VC .exe files are generated in bin_vc directory, not to interfere
13009 with binaries generated from other projects (cygwin, mingw, bcc ...)
13011 * sdcc/src/yacc.dsp: added
13013 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13014 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13015 and insert the version number definitions from .version
13017 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13019 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13020 added - genarate auto-host.h using auto-host_vc_in.h as template
13023 removed from CVS, generated automatically
13025 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13026 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13028 2002-08-11 Borut Razem <borut.razem AT siol.net>
13029 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13031 2002-08-10 Borut Razem <borut.razem AT siol.net>
13032 * src/SDCCmain.c (main):
13033 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13034 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13035 The consequence was that some temporary files were not removed.
13038 unification of code in functions tempfilename() and tempfile():
13039 function tempnam() is defined in Visual Studio 6.0 and .NET
13041 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13043 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13044 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13045 - removed compiler command line option /WX: Treats all warnings as errors
13046 - update a list of source files, included into the project
13048 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13049 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13050 changed project type to Generic Project so that can be correcly converted to VS.NET project
13052 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13054 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13056 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13058 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13059 added return 0 statements after assert() to make compiler happy
13061 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13062 added newline in the def file to keep MSC compiler satisfied
13064 * sdcc/src/z80/gen.c:
13065 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13066 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13067 - solved MSC error in function aopDump()
13069 * sdcc_vc.h: define PREFIX as "\\sdcc"
13071 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13072 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13074 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13075 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13076 - Rewrote the register banking algorithm.
13077 - Added pCode live-range analysis to registers (for now, only non-used and
13078 singly-used registers optimized away)
13080 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13082 * 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.

13103 * src/z80/peeph.def: Added transpose redundent load rule.
13105 * src/z80/main.c: Added force callee saves for jaune.
13107 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13109 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13111 2002-03-28 Johan Knol <johan AT balder>
13113 * src/SDCCval.c: fixed bug #532436
13115 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13117 Added "char *Processor" field to the port structure.
13120 Added -p option. Allows port dependent processor to be specified.
13123 Initialized the new field char *Processor field to NULL in all ports
13126 Compiler generated registers for interrupt context saving
13127 were not getting allocated.
13129 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13132 Fixed left shift. Will promote the left side of a left shift
13133 if a) left shifting more than size of operand or b) when assigned
13134 to something size > size of left side
13136 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13138 tons of changes. Register allocation has been
13139 rewritten. Added customization for the various PICs. Flow
13140 analysis is restructured. ...
13142 * src/pic/device.h:
13145 * src/pic/device.c:
13146 Added. device.c is a PIC port hack to accomodate variations
13149 2002-03-13 Michael Hope <michaelh AT vroom>
13151 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13153 2002-03-04 johanknol <johanknol AT manik>
13155 * /src/SDCCval.c: fixed
13157 const unsigned char arr[][2] = { { 0, 1 } };
13158 t18.c:1: error: Initializer element is not constant

13244 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13246 * sdcc/src/SDCCloop.c:
13247 Previous fix was not good. basic blocks that have "break" or "return" are
13248 not really partof a loop , but live ranges used in these blocks should
13249 be live thru the entire loop, so set partOfLoop but don't add them to
13252 2002-02-21 <johan AT FRIJA>
13254 * src/SDCCcse.c: fixed bug #514308
