2965 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2967 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2968 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2970 One basic decision: e.g. src/clean.mk includes further files. In order
2971 to make this work there are two solutions:
2972 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2973 run configure on them. This way they can use
2974 'include $(srcdir)/port-clean.mk'
2975 - always include clean.mk by the Makefile at the same level. To avoid
2976 that `make clean` tries to include and build Makefile.dep the
2977 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2978 implemented, because now even `make uninstall` doesn't create
2979 Makefile.in. clean.mk could be eliminated by pasting it in
2982 * debugger/mcs51/Makefile.in: build own objects from library sources
2983 (SLIB, SDCC) in current directory
2985 * configure, configure.in: renamed --disable-device-lib-build in
2986 --disable-device-lib; added --enable-doc, the required tools are
2987 searched by configure; added result message; the toolchain for the
2988 belonging ports are now only built, if the port is enabled.
2990 * support/regression/*: all output is written in directory gen, because
2991 the fwk and ports directories don't livet in the build tree using vpath
2993 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2994 --disable-device-lib, added --enable-doc, added section VPATH
2996 * sim/ucsim/configure.in,
2997 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2998 z80 are enabled by default
3000 2006-04-24 Raphael Neider <rneider AT web.de>
3002 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3003 to config word, "pic14_"-prefixed some extern functions
3004 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3005 config word has been found
3006 * src/pic/device.h: added prototypes
3007 * src/pic/pcode.c: added "pic14_"-prefix where needed
3008 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3010 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3012 (pic14emitRegularMap): ignore config words,
3013 (pic14createInterruptVect): moved generating __config directives away
3014 (picglue): have __config directives emitted
3016 2006-04-24 Borut Razem <borut.razem AT siol.net>
3018 * doc/Makefile: sync with nightly build makefile
3020 2006-04-24 Raphael Neider <rneider AT web.de>
3022 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3023 registers that have not been assigned proper liveranges,
3024 fixes #1469504 and #1474602,
3025 (pCodeRegOptimizeRegUsage): fixed typo in comment
3027 2006-04-24 Borut Razem <borut.razem AT siol.net>
3029 * device/examples/main8051.c: deleted - it was removed from CVS
3030 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3031 after the transition to Subversion
3032 * src/SDCCalloc.h: deleted - it was removed from CVS
3033 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3034 after the transition to Subversion
3035 * sim/ucsim/cpu.gif, sim/ucsim/interrupt.gif, sim/ucsim/new.gif,

3272 interrupts need an interrupt number now if they are made critical),
3273 and enabled nesting of critical functions though not for gbz80
3274 (genCritical, genEndCritical): added functions
3275 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3276 * src/z80/mappings.i: added "ei" to all mappings

3288 the left operand is shorter than the result (c* = lit-c* + int),
3290 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3293 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3295 * src/.version: increased version number to 2.5.5
3296 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3297 linking is done manually in pic16 port's _linkEdit,
3298 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3299 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3300 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3301 allocate asmop as AOP_ACC,
3302 (aopForRemat): added parameter 'bool result' in function declaration,
3303 (pic16_aopGet): return AOP_ACC when accessing WREG,
3304 (pic16_popGetTempReg): minor modification,

3315 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3316 call to allocReg, not by manually allocating a new one,
3317 (pic16_assignRegisters): now before going through the register
3318 allocating functions mark all registers as free. This eliminates some
3319 side effects resulting from peephole parser done earlier in the backbone
3321 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3379 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3380 which dumps before the function entry point a data byte which represents
3381 the number of the local variables used by the specified function, added
3382 'xinst' for initial support for Extended Instruction Support,
3383 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3384 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3385 port->fun_prefix anymore (may change later),
3386 (genFunction, genEndFunction): do not store/restore local registers for
3387 _main (this should take care the --main-return command line option in
3389 (genOr): removed some legacy pic-port instructions,
3390 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3391 performing operations with SFR's causes data to be written more than
3392 once to each SFR. Perhaps SFRs should be handled in special cases...
3393 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3395 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3396 into account for stack starting position,

3398 --extended or -y for Extended Instruction Support,
3399 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3400 (deassignLRs): *** perhaps the most important change, old 'for' code
3401 (commented out for reference), didn't account for some registers which
3402 were left marked 'not free' after a pointer operation. The change
3403 reduces register usage a lot in some cases
3405 2006-03-04 Borut Razem <borut.razem AT siol.net>

5678 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5679 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5680 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5681 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5682 always available in leading double underscore form. The C99 support is
5683 mostly missing, but it's a start.
5684 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5685 reserved identifier "__data".
5687 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5763 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5765 * device/lib/printf_large.c: removed inline assembly for portability and
5766 readability. Use printf_fast if speed or size are more important.
5767 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5768 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5770 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5772 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5773 prevent compiler warning
5775 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5777 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5778 moved to level 0 and declared as static. Also they are explicit
5779 placed in access bank. This was necessery because some times they
5780 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5781 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5782 optimizations. Currently only compare to unsigned char is implemented,
5783 * src/pic16/gen.c: added fReturnIdx array,
5784 * (struct resolvedIfx) is moved to gen.h and made public,
5785 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5786 * (aopForSym): added an optimization to directly store in stack of
5787 the operand of a SEND iCode,
5788 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5789 but as registers instead (AOP_REG) using the fReturnIdx array,
5790 * (pic16_freeAsmop): remove the freed register from the
5791 _G.sregsAlloc field,
5792 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5793 a compare of 'WREG',
5794 * (pic16_popGetTempRegCond): changed function prototype, now
5795 function takes also a bitVector argument v which holds the current
5796 set of registers that are allocated for stack access by aopForSym,
5797 registers allocated in aopForSym for accessing stack symbols are not
5798 any more part of the functions usedRegs field,
5799 * (genCall): some times aopOp is called for a stack variable to be
5800 send, aopForSym might perform the push, if this is true make sure
5801 that genCall doesn't push the variable twice by testing _G.resDirect,
5802 * (genFunction): changed testing for unspecified interrupt number
5803 from 256 to INTNO_UNSPEC,
5804 * modified selection scheme of frame pointer generation. Previously
5805 if function did use local registers a frame pointer was generated,
5806 now a frame pointer is generated only if function has arguments
5807 (that need PLUSW2 register access), or has stack arguments, or the
5808 compiler is not instructed to omit the frame pointer,
5809 * (genEndFunction): before restoring local registers that were saved
5810 in the function preamble, also restore the registers that *might*
5811 have been allocated for stack access,
5812 * (genRet): removed some old comments,
5813 * (genCmp, the active (RN's) version): added a call to the
5814 pic16_genCmp_special function to perform the compare with a more
5815 robust and optimized way,
5816 * (genInline): a feature has been added in inline code generation,
5817 which allows a wildcard variable substitution when writing inline
5818 assembly. Code is incomplete and experimental therefore undocumented,
5819 * (genCast): changed order of aopOp for result and right to allow
5820 aopForSym to directly load the result if possible,
5821 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5822 perform an optimized compare on some selected special occasions,
5823 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5824 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5825 generate an IVT any more,
5826 * src/pic16/main.c (pic16_optionsTable): added command line option
5828 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5829 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5831 * src/pic16/NOTES: Raphael Neider added in list of active developers
5832 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5833 jumptable_end to prevent bug #,
5834 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5835 inCond and outCond fields,
5836 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5837 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5838 turn off register spilling,
5839 * (packRegsForOneUse): synced with other ports' versions although it
5840 is not used currently,
5841 * (pic16_packRegisters): added an optimization while reading
5842 structure bitfields, some registers may be saved (malloc code is
5843 decreased by 80 bytes)
5845 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5847 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5848 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5849 this can be optimized more?
5851 2005-03-10 Raphael Neider <rneider AT web.de>
5853 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5854 genNearPointerGet): (hopefully) fixed access to bitfields via
5855 pointers (p->bitN = x; and x = p->bitN; failed)

6489 Adding support for replacing ljmps with sjmps in jumptables
6490 generated for switch statements. For now you need to set the
6491 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6492 Now 4 algorithms for mcs51 jumptable generation are used:
6493 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6494 addresses loaded pc-relative for up to 112 cases and stack-pushing
6495 target addresses loaded with offset from dptr for up to 256 cases.

6522 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6523 to call when a stack overflow occurs,
6524 * (malloc.h): added CVS Id tag,
6525 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6527 * added libc directory. The current version of LibC contains string
6528 functions, ctype functions and macros and some functions of the
6529 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6530 be extensively tested in the future. Standard disclaimer here.
6531 Library is not automatically build yet. But one can build it by
6532 invoking 'make' inside the libc directory.
6533 * added ADC library under libio. Preliminary version yet.
6535 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6542 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6543 * (pic16_storeForReturn): optimized return of 0,
6544 * (genCmp): experimental code for new genCmp which uses PIC18's
6545 special compare&skip instructions. Initial tests fail some times
6546 with variables grater than 1 byte in size, so new code is disabled,
6547 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6549 * (genCast): began a fix to optimize the casting of a bit to another
6550 bit, now assigning a bitfield to another bitfield will fail, sorry,
6551 * src/pic16/main.c: disabled the use of lr-support feature,
6552 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6555 bits with offset (case PO_GPR_BIT),
6556 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6558 * (isBankInstruction): modified to return 0 for no banking instruction,
6559 and 1 for banking instruction,
6560 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6561 caused stop processing pCodes after a inline assembly block,
6562 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6563 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6564 registers when it shouldn't,
6565 * src/pic16/ralloc.c (allocReg): add preliminary support for
6566 supporting a limited set of temporary registers,
6568 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6570 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6571 genDataPointerSet): ensure assignments always copy in MSB to LSB
6573 (loadRegFromAop): recognize CLRH optimization,
6574 (genFunction): optimize RECEIVE iCodes in reentrant functions
6576 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6578 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9528 code / RAM are in the same page / bank. This means the linker can
9529 safely allocate code/RAM of separate ASM files to different pages/banks.
9530 * doc/sdccman.lyx: added Slade's tips
9531 * src/mcs51/peeph.def: fixed bug #880768

9540 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
9543 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9544 strtof is not part of C89 and isn't included with Mac OS X.
9546 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9548 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
9549 shiftL2Left2Result): fixed bug #879326
9550 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

9573 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9575 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9576 loaded with the linker search paths (-L arguments) and the libraries
9577 to be linked with the current source (-l arguments). Changes
9578 currently will affect only the pic16 port.
9579 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9580 include path the port specific paths and port specific libraries,
9581 * gplink command now contains the $3 argument,
9582 * src/pic16/device.h,
9583 * src/pic16/device.c,: structure PIC_device is made public and
9584 renamed to PIC16_device, the same for variable Pics which is renamed
9585 to Pics16. Updated all references to them.

9597 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9599 Documenting changes from previous commits.
9600 * configure.in (version 1.56),
9601 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9602 when generating output files to configure the pic16 library,
9603 but now I've commented it out, since gputils aren't installed in the
9604 SF compile farm, so library won't compile
9606 * device/lib/Makefile.in (version 1.56): initially I've added in
9607 target 'all' the prerequestive 'model-pic16' so it compiled the
9608 pic16 library, but now I've commented it out for the same reasons
9610 * added targets 'model-pic16' and 'objects-pic16' to compile the
9612 * added target 'port-specific-objects-pic16' to handle the
9613 generated libraries and copy them into the build/ directory
9614 * added target 'clean-intermediate-pic16' to clean intermediate
9615 files into pic16 directory
9616 * in target 'installdirs' added line to create directory pic16 in
9617 the installation path
9619 * device/include/Makefile.in (version 1.11): in target 'install'
9620 added lines to copy all header files to installation path,
9621 * in target 'installdirs' added line create directory for pic16
9622 headers in the installation path

9637 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9638 option so that it actually works. Made it specific to the z80, since
9639 the gbz80 doesn't have these kinds of I/O ports.
9641 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9643 * device/include/z180.h,

9665 Mainly changes to support compilation of the device libraries
9666 * src/pic16/device.c: stack is allocated via symbol and not
9667 via literal number. The symbol is placed in the corresponding
9668 position of the data ram
9669 * (pic16_dump_section): relocatable and absolute uninitialized
9670 data are now emitted in sorted order to reduce section naming,
9671 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9672 weren't marked as being in the access bank,
9674 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9676 Added portion of GNU PIC Library under the directory
9677 device/include/pic16 and device/lib/pic16. These files
9678 contain the declarations of SFRs for the PIC18Fxx2 devices.
9679 The directory is initialized via configure from toplevel.
9681 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9683 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9684 the spilllocations to be compared correctly

9709 all over. Telling LaTeX to be less strict with word spacing
9710 to better keep the right margin. Changed some notes about
9711 maintainance of the ports in section 3.2.1 - is it OK like this?
9713 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9751 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9753 * src/pic16/peeph.def: all peepholes with movff are commented out,
9754 because there is a problem in the pcode peep optimizer,
9755 * src/pic16/ralloc.c: the register allocator can now reuse local

9870 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9872 A python script to validate compiler diagnostic messages. It can be
9873 used to verify that sdcc complains about bad c source code and
9874 gives a good location of the error.
9875 * support/valdiag/Makefile,
9876 * support/valdiag/valdiag.py,
9877 * support/valdiag/tests/*

9907 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9909 PIC16 port related changes:
9910 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9911 added variable stackPos,
9913 * gen.c: genCall, assignResultValue: added support for
9914 pushing/retrieving function parameters to/from stack,
9915 genFunction,genEndFunction: setup stack frame for the
9917 genAddrOf: will be changed according to bug 863624
9919 * added files genutils.c and genutils.h which contain gen*
9920 debugged and optimised functions extracted from gen.c
9922 * glue.c: added variable 'externs' which holds extern symbols,
9923 pic16emitRegularMap: is modified to properly handle relocatable
9924 symbols under the new scheme,
9925 pic16createInterruptVect: is modified
9926 pic16printPublics: is modified to emit 'global' assembler directives,
9927 added pic16_printExterns to print extern symbols,
9928 pic16glue: initializes stack/frame pointer in the beginning of
9929 the assembly output. Temporary hack, will be corrected later,
9930 because gplink yet does not support stack and SDCC does not
9931 yet support a type of crt0.o object to create the final binary.
9933 * Removed many lines that contain 8051 legacy code.
9934 * The code is finally placed under a 'code' directive.
9935 * Added port specific options.
9937 * _process_pragma: simplified since now we do not need *special*
9938 include file to define SFR registers. But a separate header
9939 will be needed. This will be developed later.
9940 * _pic16_parseOptions: added, parses port specific options:
9941 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9942 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9943 --preplace-udata-with=
9945 * _pic16_setDefaultOptions: modified to initialize section names,
9946 but hack is temporarly out of order since it needs improvement.
9947 * _pic16_genAssemblerPreamble: configuration words are emitted by
9948 their address instead of their name. This part is incomplete and
9949 supports only the 18Fxx2 devices. Other devices will emit an error
9950 during assembly since they do not contain the same set of config
9952 * _pic16_genIVT: is modified,
9954 * pcode.c: added definitions for some hardware registers that are needed
9956 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9957 All PCI entries are updated. Now LFSR is supported.
9958 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9959 * added pic16_newpCodeOpLit2 to support instructions with
9960 two literal arguments
9961 * pic16_pCode2str: corrected code that emits assembler instructions
9962 with two literal operands and those that have an access bit modifier
9963 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9964 this fixes a bug which caused some labels to be lost, when an
9965 assembler directive was added, i.e. banksel,
9966 * pic16_FixRegisterBanking: improved logic that causes the insertion
9968 * InlineFunction: functions that are called once, are not any more
9969 inlined. This can be a port option in the future,
9971 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9973 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9974 hold the corresponding uninitialized symbols,
9975 * pic16_allocProcessorRegister: registers have explicit marked the
9977 * pic16_allocInternalRegister: registers are explicit marked as
9979 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9980 processing list, so bit registers were lost,
9983 * ralloc.h: added field 'accessBank' and original symbol operand
9984 in register definition,
9985 * removed the field isMapped from register definition,
9987 ** Several functions have been removed from various sources:
9988 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9989 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9990 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9991 pic16_assignRelocatableRegisters
9993 ** others have been introduced:
9994 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9995 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9997 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9999 * support/scripts/inc2h.pl: changed definition of BIT_AT
10000 to emit 'sbit at' instead of 'bit at'. This was a request.
10002 PIC16 port related preliminary changes:
10003 * gen.c: prefixed function popRegFromString with
10004 pic16_ and all references to it corrected
10005 * pcode.c: all pic16_pc_* hardware registers prefixed
10006 with underscore (_),
10007 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10008 * ralloc.c: newReg(): when register is REG_SFR then
10009 set address to rIdx,
10010 pic16_allocProcessorRegister(): marks register wasUsed=0
10011 pic16_writeUsedRegs(): added a call to assign processor
10012 registers via pic16_assignFixedRegisters

10016 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10017 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10018 variables in unused register banks. Also the SSEG is placed
10019 wherever there is enough space for it, and IDATA can be anywhere
10020 in internal RAM. For now compile using -Wl-Y[stack_size].
10021 The mem file is different for this option as well, since it
10022 makes no sense of talking about DSEG lenght.
10024 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

11037 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11038 If they pop r0/r1 they must be called in the opposite order than aopOp().
11039 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11040 (resp. --stack-auto), prepared for --xstack
11042 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11051 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11053 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11054 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11055 type for bits was changed. It resulted in bit variables becoming
11056 global, which is not permitted in PIC 14 assembly output.
11058 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11060 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11062 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11064 Z80 and MCS51 linkers complaint if a public symbol is defined
11065 in more than one library module:
11069 * as/mcs51/Makefile.in
11071 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11073 A few small changes that speed up the peephole optimizer.
11077 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11079 Try to make the peephole optimizer smarter by maintaining
11080 an association between the assembly source code and the
11081 iCodes that originated them. Put this information to use
11082 with a new peephole rule condition "notVolatile" so that
11083 the rules can be aggressive yet still safe.
11088 * src/mcs51/peeph.def
11090 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11094 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11095 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11096 if the left or right operand symbols have the accuse flag set.
11098 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11100 Changed the type of the result of the ! (NOT) operator to char;
11101 previously it returned the same type as the source. This allows
11102 us to eliminate all the genFloatNot functions (all of its target
11103 implementations were very buggy) since !float can use the same
11106 * src/SDCCicode.c (ast2iCode): ! returns char
11107 * src/mcs51/gen.c (genNot, genNotFloat),
11108 * src/ds390/gen.c (genNot, genNotFloat),
11109 * src/z80/gen.c (genNot, genNotFloat),
11110 * src/pic/gen.c (genNot, genNotFloat),
11111 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11113 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11115 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11116 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11117 during interrupts. Ensure WSAVE is located at a shared bank address.
11118 2. Fixed page selection in some places
11119 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11120 the registers name strings.
11121 4. Fixed "signed / unsigned compare" compiler warnings.
11122 5. The PIC port manages its own allocation of the general purpose
11123 registers, but makes no attempt to reuse them. As a result when
11124 compiling it soon runs out of general purpose registers. Some
11125 additional code was added to the files pcode.c and device.c to walk
11126 through the function call tree and rename the registers so that they
11136 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11137 genPlus() & genMinus() when the result is the same as left or right
11139 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11143 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11145 Made bitfield a distinct type from bit so that bitfields
11146 convert as per ANSI C and bits retain their traditional
11147 boolean style behaviour. Implemented bitfield support in
11155 * src/ds390/gen.c: bit v bitfield split
11156 * src/z80/gen.c: New support for bitfields
11157 * support/regression/tests/bitfields.c: reenabled z80,
11160 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11162 Rules 246.x, 247.x relate to bitfields, the others speed up
11163 access to xdata mapped I/O devices.
11165 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11167 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11169 Cleaned up genPackBits and genUnpackBits and added two helper
11170 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11171 for literal assignments in genPackBits (thanks to Frieder for
11177 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11179 Fixed bug #748310 (pointer to function type mishandled when the
11180 function name is omitted). Also fixed a SIGSEGV when a function
11181 attribute (reentrant, etc) is used on a non-function or on a
11182 function but misplaced before the parameter list.
11184 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11186 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11187 * support/Util/SDCCerr.h,
11188 * support/Util/SDCCerr.c: Added func attr misuse error msg
11190 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11192 Fixed bug #787649 by anonymous
11193 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11194 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11196 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11198 Fixed numerous bitfield problems.

11209 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11211 Made the constant following the "interrupt" keyword optional. If
11212 omitted, the function will not automatically be given an entry
11213 in the interrupt vector table (similar to #pragma NOIV, but
11214 less syntacticly kludgy). The interrupt number is also now
11215 range checked. Also fixed a bug in the high order bit example
11222 * support/Util/SDCCerr.c
11223 * support/Util/SDCCerr.h
11226 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11229 * src/SDCCicode.c (operandOperation): rewritten some ops
11230 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11231 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11233 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11234 be re-activated by defining REDUCE_LITERALS)
11235 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11236 unsigned, but are signed by default
11237 * src/SDCCval.c (constVal): rearranged
11238 * src/SDCCval.c (valMod): preliminary fix
11239 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11279 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11280 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11281 constants are unsigned; added recognition of "u" flag for unsigned
11282 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11283 * src/SDCCval.c (valDiv, valMod): fixed signdness
11284 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11285 signedness of modulo, left and right shift

11692 the regression tests I'm not brave enough to enable 245.b, 245.c
11693 * doc/sdccman.lyx: added latex preamble for hyperref package.
11694 Using pdflatex this will give you a hyperlinked pdf file with

11745 added if/endif conditional macros to remove options help
11746 messages from optionsTable when a port is not configured, added
11747 support for the PIc16 port in the ports table, when executing
11748 the compiler with no port specified on command line, a default
11749 port is selected with the new macro DEFAULT_PORT which is
11750 defined in port.h, in setDefaultOptions() linkOptions is removed
11751 from initialization assignment, since now it is a set,
11752 parseCmdLine uses setParseWithComma for linkOptions, in
11753 linkEdit() linkOptions are accessed with new function indexSet()
11754 which returns the i'th item of a set variable. See SDCCset.c, in
11755 linkEdit() when calling buildCmdLine(), added linkOptions as
11756 last argument. Now users can pass arguments to gplink via the
11757 -Wl option, main() uses pic16glue() to glue up pic16 programs

11770 * src/pic16/main.c: __config directives are commented out to stop
11771 gpasm complaining and test the linkage with gplink, _linkCmd and
11772 _asmCmd changed to be more gplink and gpasm friendly
11773 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11774 produced an error when parsed, peep rule 12 is added to utilize
11775 movff, but it is commented out since the pCode does not support
11776 yet a command with 2 address arguments
11778 2003-05-18 <johan AT balder>
11780 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11807 2003-05-11 Borut Razem <borut.razem AT siol.net>
11809 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

12796 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
12798 2003-01-07 <johan AT balder>
12800 * src/SDCCast.c (decorateType): fixed bug #600035
12802 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
12803 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12804 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12805 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
12806 * src/pic/pcode.c: outcommented unused variable to remove warnings
12807 * src/pic/ralloc.c: outcommented unused variable to remove warnings
12809 2003-01-06 <karl AT turbobit.com>
12810 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
12813 2003-01-06 <johan AT balder>
12815 * src/SDCCicode.c: fixed array add
12817 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12818 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12819 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12821 2003-01-04 <johan AT balder>
12823 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12825 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12826 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12828 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12829 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12830 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12832 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12833 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12835 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12836 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12838 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12839 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12841 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12843 * in /sdcc/as/mcs51/ changed these files in order to create an
12844 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12845 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12846 following files to include the previous two files: aslink.dsp,
12847 Makefile.aslink, Makefile.bcc, and Makefile.in.
12849 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12850 .adb instead of .cdb
12852 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12854 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12855 value from option --iram-size.
12857 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12859 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12862 2002-09-18 <wiml AT hhhh.org>
12864 * SDCClrange.h: exposed setFromRange() and setToRange()
12865 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12866 packRegsForAccUse() (bug 542397)
12867 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12868 multiple times and emitting the fetch operations more than once
12869 added aopGetUsesAcc() function to allow binary operators to
12870 fetch their operands in the correct order; made genMinus() emit
12871 compact code for X = LITERAL - Y
12873 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12874 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12875 sprintf() in line 1267.
12877 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12878 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12881 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12882 Changes to aslink (All the changes are marked with 'JCF'):
12884 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12887 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12888 area BSEG. Also moves, if possible, the DATA area down into the internal
12889 ram so more space is available.
12891 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12894 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12895 not bytes. Function summary() which creates a memory usage summary
12896 file with extension .mem. Reports of overlaping stack and small stack
12897 size. If the space for the stack is less than 16 bytes aslink trows a
12900 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12901 the 8051. Option 'y' for memory summary output file.
12903 Changes to sdcc (All the changes are marked with 'JCF'):
12905 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12907 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12908 overlaying area for it (uses RegBankUsed[4]).
12910 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12911 bank zero as used by default. By default aslink locates the stack
12912 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12913 the creation of the .mem file. Delegates the allocation of data area
12914 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12915 the begining of the stack area to aslink.
12917 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12918 glue() in SDCCglue.c creates an area for it.
12920 2002-09-03 Borut Razem <borut.razem AT siol.net>
12921 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12922 sdcc/src/pic/glue.c:
12923 introduced atexit() handler for teporay files removal in case of
12924 errors, assertions, ...
12926 2002-08-29 Borut Razem <borut.razem AT siol.net>
12927 * sdcc/support/cpp2/auto-host_vc_in.h:
12928 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12929 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12930 Maybe there is a similar problem with BORLANDC? It should be checked!
12932 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12933 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12934 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12935 was not executed, and the compiler (cl) launched a warning:
12936 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12938 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12939 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12941 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12942 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12944 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12945 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12946 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12947 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12948 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12949 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12950 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12951 - added Release configuration in VS projects
12952 - review of compiler an linker options
12953 - VC .exe files are generated in bin_vc directory, not to interfere
12954 with binaries generated from other projects (cygwin, mingw, bcc ...)
12956 * sdcc/src/yacc.dsp: added
12958 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12959 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12960 and insert the version number definitions from .version
12962 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12964 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12965 added - genarate auto-host.h using auto-host_vc_in.h as template
12968 removed from CVS, generated automatically
12970 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12971 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12973 2002-08-11 Borut Razem <borut.razem AT siol.net>
12974 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12976 2002-08-10 Borut Razem <borut.razem AT siol.net>
12977 * src/SDCCmain.c (main):
12978 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12979 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12980 The consequence was that some temporary files were not removed.
12983 unification of code in functions tempfilename() and tempfile():
12984 function tempnam() is defined in Visual Studio 6.0 and .NET
12986 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12988 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12989 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12990 - removed compiler command line option /WX: Treats all warnings as errors
12991 - update a list of source files, included into the project
12993 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12994 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12995 changed project type to Generic Project so that can be correcly converted to VS.NET project
12997 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12999 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13001 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13003 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13004 added return 0 statements after assert() to make compiler happy
13006 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13007 added newline in the def file to keep MSC compiler satisfied
13009 * sdcc/src/z80/gen.c:
13010 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13011 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13012 - solved MSC error in function aopDump()
13014 * sdcc_vc.h: define PREFIX as "\\sdcc"
13016 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13017 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13019 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13020 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13021 - Rewrote the register banking algorithm.
13022 - Added pCode live-range analysis to registers (for now, only non-used and
13023 singly-used registers optimized away)
13025 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13027 * 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.

13050 * src/z80/main.c: Added force callee saves for jaune.
13052 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13054 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13056 2002-03-28 Johan Knol <johan AT balder>
13058 * src/SDCCval.c: fixed bug #532436
13060 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13062 Added "char *Processor" field to the port structure.
13065 Added -p option. Allows port dependent processor to be specified.
13068 Initialized the new field char *Processor field to NULL in all ports
13071 Compiler generated registers for interrupt context saving
13072 were not getting allocated.
13074 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13077 Fixed left shift. Will promote the left side of a left shift
13078 if a) left shifting more than size of operand or b) when assigned
13079 to something size > size of left side
13081 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13083 tons of changes. Register allocation has been
13084 rewritten. Added customization for the various PICs. Flow
13085 analysis is restructured. ...
13087 * src/pic/device.h:
13090 * src/pic/device.c:
13091 Added. device.c is a PIC port hack to accomodate variations
13094 2002-03-13 Michael Hope <michaelh AT vroom>
13096 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13098 2002-03-04 johanknol <johanknol AT manik>
13100 * /src/SDCCval.c: fixed
13102 const unsigned char arr[][2] = { { 0, 1 } };
13103 t18.c:1: error: Initializer element is not constant

13189 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13191 * sdcc/src/SDCCloop.c:
13192 Previous fix was not good. basic blocks that have "break" or "return" are
13193 not really partof a loop , but live ranges used in these blocks should
13194 be live thru the entire loop, so set partOfLoop but don't add them to
13197 2002-02-21 <johan AT FRIJA>
13199 * src/SDCCcse.c: fixed bug #514308
13201 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13204 Fixed BUG #519583. If a conditional block ended in a return/break
13205 statement inside a loop, it was not being considered part of the loop.
13207 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13209 2002-02-10 Karl Bongers <karl AT turbobit.com>
13212 Fixed up SDCDB debugger somewhat. Updated debugger/README
13213 with lots of comments and notes.
13215 * device/examples/test2.c:
13216 Fix bug, "red" variable not being initialized(compiler complained).
13218 * device/examples/Makefile, examples/test3.c:
13219 Add Makefile in device/examples folder, compiles test3.c
13220 for use as a multiple module SDCDB test case.
13222 * sim/ucsim/cmd.src/cmdset.cc:
13223 Took out debug printfs in ucsim "next" command.
13225 * sim/ucsim/xa.src:
13226 Karl and Johan start ucsim XA support. Most dissassembly working,
13227 about 75% emulation done(plenty of work remaining).
13229 * sim/ucsim/z80.src:
13230 Add Z80 support to ucsim, add test-ucz80 regression test,
13231 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13232 Notice z80 compiler fails on examples/test3.c/crc code.
13234 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13236 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
13237 Added support for --parms-in-bank1
13239 * src/ds390/peeph.def:
13240 added a few more peephole optimzations
13242 * src/ds390/main.c:
13243 1) added __builtin_inp & __builtin_outp used to read in data of given length
13244 from a memory mapped port
13245 2) added __builtin_memcmp
13246 3) added __builtin_swapw swap bytes of a short
13248 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13249 1) handle multiple send & receives from register bank1
13250 2) ralloc can now allocate DPTR1 to some liveRanges
13252 * src/SDCCsymt.c, src/SDCCsymt.h:
13253 changes to handle multiple sends & receives
13255 * src/SDCCptropt.h:
13256 added some pointer arithmetic optimization
13258 * src/SDCCptropt.c:
13259 added some pointer arithmetic optimizations but not stable yet so not
13260 called from anywhere (will get this working shortly)
13262 * src/SDCCopt.c: fixed for multiple sends & receives
