2986 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2988 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2989 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2991 One basic decision: e.g. src/clean.mk includes further files. In order
2992 to make this work there are two solutions:
2993 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2994 run configure on them. This way they can use
2995 'include $(srcdir)/port-clean.mk'
2996 - always include clean.mk by the Makefile at the same level. To avoid
2997 that `make clean` tries to include and build Makefile.dep the
2998 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2999 implemented, because now even `make uninstall` doesn't create
3000 Makefile.in. clean.mk could be eliminated by pasting it in
3003 * debugger/mcs51/Makefile.in: build own objects from library sources
3004 (SLIB, SDCC) in current directory
3006 * configure, configure.in: renamed --disable-device-lib-build in
3007 --disable-device-lib; added --enable-doc, the required tools are
3008 searched by configure; added result message; the toolchain for the
3009 belonging ports are now only built, if the port is enabled.
3011 * support/regression/*: all output is written in directory gen, because
3012 the fwk and ports directories don't livet in the build tree using vpath
3014 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3015 --disable-device-lib, added --enable-doc, added section VPATH
3017 * sim/ucsim/configure.in,
3018 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3019 z80 are enabled by default
3021 2006-04-24 Raphael Neider <rneider AT web.de>
3023 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3024 to config word, "pic14_"-prefixed some extern functions
3025 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3026 config word has been found
3027 * src/pic/device.h: added prototypes
3028 * src/pic/pcode.c: added "pic14_"-prefix where needed
3029 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3031 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3033 (pic14emitRegularMap): ignore config words,
3034 (pic14createInterruptVect): moved generating __config directives away

3269 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3271 * src/mcs51/gen.c (genCall): fixed bug 1457608
3273 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3292 implemented patch 1120823 Thanks to Willy De la Court (normal
3293 interrupts need an interrupt number now if they are made critical),
3294 and enabled nesting of critical functions though not for gbz80
3295 (genCritical, genEndCritical): added functions
3296 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3297 * src/z80/mappings.i: added "ei" to all mappings

3309 the left operand is shorter than the result (c* = lit-c* + int),
3311 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3314 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3316 * src/.version: increased version number to 2.5.5
3317 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3318 linking is done manually in pic16 port's _linkEdit,
3319 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3320 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3321 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3322 allocate asmop as AOP_ACC,
3323 (aopForRemat): added parameter 'bool result' in function declaration,
3324 (pic16_aopGet): return AOP_ACC when accessing WREG,
3325 (pic16_popGetTempReg): minor modification,

3336 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3337 call to allocReg, not by manually allocating a new one,
3338 (pic16_assignRegisters): now before going through the register
3339 allocating functions mark all registers as free. This eliminates some
3340 side effects resulting from peephole parser done earlier in the backbone
3342 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3399 * src/pic16/gen.c (genPcall): fixed bug #1443644
3400 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3401 which dumps before the function entry point a data byte which represents
3402 the number of the local variables used by the specified function, added
3403 'xinst' for initial support for Extended Instruction Support,
3404 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3405 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3406 port->fun_prefix anymore (may change later),
3407 (genFunction, genEndFunction): do not store/restore local registers for
3408 _main (this should take care the --main-return command line option in
3410 (genOr): removed some legacy pic-port instructions,
3411 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3412 performing operations with SFR's causes data to be written more than
3413 once to each SFR. Perhaps SFRs should be handled in special cases...
3414 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3416 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3417 into account for stack starting position,

3419 --extended or -y for Extended Instruction Support,
3420 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3421 (deassignLRs): *** perhaps the most important change, old 'for' code
3422 (commented out for reference), didn't account for some registers which
3423 were left marked 'not free' after a pointer operation. The change
3424 reduces register usage a lot in some cases
3426 2006-03-04 Borut Razem <borut.razem AT siol.net>
3428 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5699 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5700 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5701 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5702 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5703 always available in leading double underscore form. The C99 support is
5704 mostly missing, but it's a start.
5705 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5706 reserved identifier "__data".

5784 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5786 * device/lib/printf_large.c: removed inline assembly for portability and
5787 readability. Use printf_fast if speed or size are more important.
5788 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5789 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5791 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5793 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5794 prevent compiler warning
5796 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5798 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5799 moved to level 0 and declared as static. Also they are explicit
5800 placed in access bank. This was necessery because some times they
5801 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5802 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5803 optimizations. Currently only compare to unsigned char is implemented,
5804 * src/pic16/gen.c: added fReturnIdx array,
5805 * (struct resolvedIfx) is moved to gen.h and made public,
5806 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5807 * (aopForSym): added an optimization to directly store in stack of
5808 the operand of a SEND iCode,
5809 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5810 but as registers instead (AOP_REG) using the fReturnIdx array,
5811 * (pic16_freeAsmop): remove the freed register from the
5812 _G.sregsAlloc field,
5813 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5814 a compare of 'WREG',
5815 * (pic16_popGetTempRegCond): changed function prototype, now
5816 function takes also a bitVector argument v which holds the current
5817 set of registers that are allocated for stack access by aopForSym,
5818 registers allocated in aopForSym for accessing stack symbols are not
5819 any more part of the functions usedRegs field,
5820 * (genCall): some times aopOp is called for a stack variable to be
5821 send, aopForSym might perform the push, if this is true make sure
5822 that genCall doesn't push the variable twice by testing _G.resDirect,
5823 * (genFunction): changed testing for unspecified interrupt number
5824 from 256 to INTNO_UNSPEC,
5825 * modified selection scheme of frame pointer generation. Previously
5826 if function did use local registers a frame pointer was generated,
5827 now a frame pointer is generated only if function has arguments
5828 (that need PLUSW2 register access), or has stack arguments, or the
5829 compiler is not instructed to omit the frame pointer,
5830 * (genEndFunction): before restoring local registers that were saved
5831 in the function preamble, also restore the registers that *might*
5832 have been allocated for stack access,
5833 * (genRet): removed some old comments,
5834 * (genCmp, the active (RN's) version): added a call to the
5835 pic16_genCmp_special function to perform the compare with a more
5836 robust and optimized way,
5837 * (genInline): a feature has been added in inline code generation,
5838 which allows a wildcard variable substitution when writing inline
5839 assembly. Code is incomplete and experimental therefore undocumented,
5840 * (genCast): changed order of aopOp for result and right to allow
5841 aopForSym to directly load the result if possible,
5842 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5843 perform an optimized compare on some selected special occasions,
5844 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5845 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5846 generate an IVT any more,
5847 * src/pic16/main.c (pic16_optionsTable): added command line option
5849 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5850 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5852 * src/pic16/NOTES: Raphael Neider added in list of active developers
5853 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5854 jumptable_end to prevent bug #,
5855 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5856 inCond and outCond fields,
5857 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5858 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5859 turn off register spilling,
5860 * (packRegsForOneUse): synced with other ports' versions although it
5861 is not used currently,
5862 * (pic16_packRegisters): added an optimization while reading
5863 structure bitfields, some registers may be saved (malloc code is
5864 decreased by 80 bytes)
5866 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5868 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5869 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5870 this can be optimized more?
5872 2005-03-10 Raphael Neider <rneider AT web.de>
5874 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5875 genNearPointerGet): (hopefully) fixed access to bitfields via
5876 pointers (p->bitN = x; and x = p->bitN; failed)
5878 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6510 Adding support for replacing ljmps with sjmps in jumptables
6511 generated for switch statements. For now you need to set the
6512 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6513 Now 4 algorithms for mcs51 jumptable generation are used:
6514 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6515 addresses loaded pc-relative for up to 112 cases and stack-pushing
6516 target addresses loaded with offset from dptr for up to 256 cases.
6518 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6519 * src/mcs51/main.c: adapted constants for switch table generation

6543 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6544 to call when a stack overflow occurs,
6545 * (malloc.h): added CVS Id tag,
6546 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6548 * added libc directory. The current version of LibC contains string
6549 functions, ctype functions and macros and some functions of the
6550 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6551 be extensively tested in the future. Standard disclaimer here.
6552 Library is not automatically build yet. But one can build it by
6553 invoking 'make' inside the libc directory.
6554 * added ADC library under libio. Preliminary version yet.

6563 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6564 * (pic16_storeForReturn): optimized return of 0,
6565 * (genCmp): experimental code for new genCmp which uses PIC18's
6566 special compare&skip instructions. Initial tests fail some times
6567 with variables grater than 1 byte in size, so new code is disabled,
6568 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6570 * (genCast): began a fix to optimize the casting of a bit to another
6571 bit, now assigning a bitfield to another bitfield will fail, sorry,
6572 * src/pic16/main.c: disabled the use of lr-support feature,
6573 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6576 bits with offset (case PO_GPR_BIT),
6577 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6579 * (isBankInstruction): modified to return 0 for no banking instruction,
6580 and 1 for banking instruction,
6581 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6582 caused stop processing pCodes after a inline assembly block,
6583 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6584 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6585 registers when it shouldn't,
6586 * src/pic16/ralloc.c (allocReg): add preliminary support for
6587 supporting a limited set of temporary registers,
6589 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6591 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

6594 (loadRegFromAop): recognize CLRH optimization,
6595 (genFunction): optimize RECEIVE iCodes in reentrant functions
6597 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9519 (valBitwise): fixed bug #882876
9520 (valMinus): added promotion
9521 (valLogicAndOr): result is unsigned
9522 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
9523 * src/SDCCsymt.c (computeType),
9524 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
9525 must not cause an unsigned operation
9526 * src/pic/glue (pic14emitRegularMap),
9527 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
9529 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
9531 * src/pic/pcode.c (PCodeID): commented out left over debug code
9533 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
9535 * support/valdiag/tests/overflow.c: added shift tests
9543 * src/pic/pcodepeep.c,
9544 * src/pic/pcoderegs.c,
9546 * src/pic/ralloc.h: applied patch from Slade Rich;
9547 added support for multiple code pages and multiple RAM banks on the
9548 PIC 14 port. The ASM files now no longer simply assume all the
9549 code / RAM are in the same page / bank. This means the linker can
9550 safely allocate code/RAM of separate ASM files to different pages/banks.
9551 * doc/sdccman.lyx: added Slade's tips
9552 * src/mcs51/peeph.def: fixed bug #880768

9561 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
9564 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9565 strtof is not part of C89 and isn't included with Mac OS X.
9567 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9594 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9596 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9597 loaded with the linker search paths (-L arguments) and the libraries
9598 to be linked with the current source (-l arguments). Changes
9599 currently will affect only the pic16 port.
9600 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9601 include path the port specific paths and port specific libraries,
9602 * gplink command now contains the $3 argument,
9603 * src/pic16/device.h,
9604 * src/pic16/device.c,: structure PIC_device is made public and
9605 renamed to PIC16_device, the same for variable Pics which is renamed

9620 Documenting changes from previous commits.
9621 * configure.in (version 1.56),
9622 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9623 when generating output files to configure the pic16 library,
9624 but now I've commented it out, since gputils aren't installed in the
9625 SF compile farm, so library won't compile
9627 * device/lib/Makefile.in (version 1.56): initially I've added in
9628 target 'all' the prerequestive 'model-pic16' so it compiled the
9629 pic16 library, but now I've commented it out for the same reasons
9631 * added targets 'model-pic16' and 'objects-pic16' to compile the
9633 * added target 'port-specific-objects-pic16' to handle the
9634 generated libraries and copy them into the build/ directory
9635 * added target 'clean-intermediate-pic16' to clean intermediate
9636 files into pic16 directory
9637 * in target 'installdirs' added line to create directory pic16 in
9638 the installation path
9640 * device/include/Makefile.in (version 1.11): in target 'install'
9641 added lines to copy all header files to installation path,
9642 * in target 'installdirs' added line create directory for pic16
9643 headers in the installation path

9658 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9659 option so that it actually works. Made it specific to the z80, since
9660 the gbz80 doesn't have these kinds of I/O ports.
9662 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9664 * device/include/z180.h,

9686 Mainly changes to support compilation of the device libraries
9687 * src/pic16/device.c: stack is allocated via symbol and not
9688 via literal number. The symbol is placed in the corresponding
9689 position of the data ram
9690 * (pic16_dump_section): relocatable and absolute uninitialized
9691 data are now emitted in sorted order to reduce section naming,
9692 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9693 weren't marked as being in the access bank,
9695 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9697 Added portion of GNU PIC Library under the directory
9698 device/include/pic16 and device/lib/pic16. These files
9699 contain the declarations of SFRs for the PIC18Fxx2 devices.
9700 The directory is initialized via configure from toplevel.
9702 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9704 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

9730 all over. Telling LaTeX to be less strict with word spacing
9731 to better keep the right margin. Changed some notes about
9732 maintainance of the ports in section 3.2.1 - is it OK like this?
9734 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9774 * src/pic16/peeph.def: all peepholes with movff are commented out,
9775 because there is a problem in the pcode peep optimizer,
9776 * src/pic16/ralloc.c: the register allocator can now reuse local

9928 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9930 PIC16 port related changes:
9931 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9932 added variable stackPos,
9934 * gen.c: genCall, assignResultValue: added support for
9935 pushing/retrieving function parameters to/from stack,
9936 genFunction,genEndFunction: setup stack frame for the
9938 genAddrOf: will be changed according to bug 863624
9940 * added files genutils.c and genutils.h which contain gen*
9941 debugged and optimised functions extracted from gen.c
9943 * glue.c: added variable 'externs' which holds extern symbols,
9944 pic16emitRegularMap: is modified to properly handle relocatable
9945 symbols under the new scheme,
9946 pic16createInterruptVect: is modified
9947 pic16printPublics: is modified to emit 'global' assembler directives,
9948 added pic16_printExterns to print extern symbols,
9949 pic16glue: initializes stack/frame pointer in the beginning of
9950 the assembly output. Temporary hack, will be corrected later,
9951 because gplink yet does not support stack and SDCC does not
9952 yet support a type of crt0.o object to create the final binary.
9954 * Removed many lines that contain 8051 legacy code.
9955 * The code is finally placed under a 'code' directive.
9956 * Added port specific options.
9958 * _process_pragma: simplified since now we do not need *special*
9959 include file to define SFR registers. But a separate header
9960 will be needed. This will be developed later.
9961 * _pic16_parseOptions: added, parses port specific options:
9962 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9963 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9964 --preplace-udata-with=
9966 * _pic16_setDefaultOptions: modified to initialize section names,
9967 but hack is temporarly out of order since it needs improvement.
9968 * _pic16_genAssemblerPreamble: configuration words are emitted by
9969 their address instead of their name. This part is incomplete and
9970 supports only the 18Fxx2 devices. Other devices will emit an error
9971 during assembly since they do not contain the same set of config
9973 * _pic16_genIVT: is modified,
9975 * pcode.c: added definitions for some hardware registers that are needed
9977 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9978 All PCI entries are updated. Now LFSR is supported.
9979 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9980 * added pic16_newpCodeOpLit2 to support instructions with
9981 two literal arguments
9982 * pic16_pCode2str: corrected code that emits assembler instructions
9983 with two literal operands and those that have an access bit modifier
9984 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9985 this fixes a bug which caused some labels to be lost, when an
9986 assembler directive was added, i.e. banksel,
9987 * pic16_FixRegisterBanking: improved logic that causes the insertion
9989 * InlineFunction: functions that are called once, are not any more
9990 inlined. This can be a port option in the future,
9992 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9994 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9995 hold the corresponding uninitialized symbols,
9996 * pic16_allocProcessorRegister: registers have explicit marked the
9998 * pic16_allocInternalRegister: registers are explicit marked as
10000 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10001 processing list, so bit registers were lost,
10004 * ralloc.h: added field 'accessBank' and original symbol operand
10005 in register definition,
10006 * removed the field isMapped from register definition,
10008 ** Several functions have been removed from various sources:
10009 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10010 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10011 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10012 pic16_assignRelocatableRegisters
10014 ** others have been introduced:
10015 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection

10018 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10020 * support/scripts/inc2h.pl: changed definition of BIT_AT
10021 to emit 'sbit at' instead of 'bit at'. This was a request.
10023 PIC16 port related preliminary changes:
10024 * gen.c: prefixed function popRegFromString with
10025 pic16_ and all references to it corrected
10026 * pcode.c: all pic16_pc_* hardware registers prefixed
10027 with underscore (_),
10028 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10029 * ralloc.c: newReg(): when register is REG_SFR then
10030 set address to rIdx,
10031 pic16_allocProcessorRegister(): marks register wasUsed=0
10032 pic16_writeUsedRegs(): added a call to assign processor
10033 registers via pic16_assignFixedRegisters
10035 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10037 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10038 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10039 variables in unused register banks. Also the SSEG is placed
10040 wherever there is enough space for it, and IDATA can be anywhere
10041 in internal RAM. For now compile using -Wl-Y[stack_size].
10042 The mem file is different for this option as well, since it
10043 makes no sense of talking about DSEG lenght.
10045 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10047 * src/SDCClrange.c: fixed bug 869095 that caused segfault

10294 it breaks with bitfields, extern declarations, and gcse analysis.
10295 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10296 could be assigned through a pointer, so don't complain.

11038 and JUMPTABLE iCodes properly now (worked by accident before)
11039 * src/mcs51/gen.c (leftRightUseAcc),
11040 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11041 iCode properly now. Use getSize instead of nRegs since a & b
11042 aren't part of the nRegs tally.
11044 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11046 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11056 copied from genNearPointerSet()
11057 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11058 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11059 If they pop r0/r1 they must be called in the opposite order than aopOp().
11060 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11061 (resp. --stack-auto), prepared for --xstack
11063 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11072 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11074 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11075 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11076 type for bits was changed. It resulted in bit variables becoming
11077 global, which is not permitted in PIC 14 assembly output.
11079 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11081 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11083 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11085 Z80 and MCS51 linkers complaint if a public symbol is defined
11086 in more than one library module:

11092 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11094 A few small changes that speed up the peephole optimizer.
11098 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11100 Try to make the peephole optimizer smarter by maintaining
11101 an association between the assembly source code and the
11102 iCodes that originated them. Put this information to use
11103 with a new peephole rule condition "notVolatile" so that
11104 the rules can be aggressive yet still safe.
11109 * src/mcs51/peeph.def
11111 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11115 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11116 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11117 if the left or right operand symbols have the accuse flag set.
11119 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11121 Changed the type of the result of the ! (NOT) operator to char;
11122 previously it returned the same type as the source. This allows
11123 us to eliminate all the genFloatNot functions (all of its target
11124 implementations were very buggy) since !float can use the same
11127 * src/SDCCicode.c (ast2iCode): ! returns char
11128 * src/mcs51/gen.c (genNot, genNotFloat),
11129 * src/ds390/gen.c (genNot, genNotFloat),
11130 * src/z80/gen.c (genNot, genNotFloat),
11131 * src/pic/gen.c (genNot, genNotFloat),

11136 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11137 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11138 during interrupts. Ensure WSAVE is located at a shared bank address.
11139 2. Fixed page selection in some places
11140 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11141 the registers name strings.
11142 4. Fixed "signed / unsigned compare" compiler warnings.
11143 5. The PIC port manages its own allocation of the general purpose
11144 registers, but makes no attempt to reuse them. As a result when
11145 compiling it soon runs out of general purpose registers. Some
11146 additional code was added to the files pcode.c and device.c to walk
11147 through the function call tree and rename the registers so that they
11157 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11158 genPlus() & genMinus() when the result is the same as left or right
11160 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11164 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11166 Made bitfield a distinct type from bit so that bitfields
11167 convert as per ANSI C and bits retain their traditional
11168 boolean style behaviour. Implemented bitfield support in
11176 * src/ds390/gen.c: bit v bitfield split
11177 * src/z80/gen.c: New support for bitfields
11178 * support/regression/tests/bitfields.c: reenabled z80,
11181 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11183 Rules 246.x, 247.x relate to bitfields, the others speed up
11184 access to xdata mapped I/O devices.
11186 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11188 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11190 Cleaned up genPackBits and genUnpackBits and added two helper
11191 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11192 for literal assignments in genPackBits (thanks to Frieder for
11198 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11200 Fixed bug #748310 (pointer to function type mishandled when the
11201 function name is omitted). Also fixed a SIGSEGV when a function
11202 attribute (reentrant, etc) is used on a non-function or on a
11203 function but misplaced before the parameter list.
11205 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11207 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11208 * support/Util/SDCCerr.h,
11209 * support/Util/SDCCerr.c: Added func attr misuse error msg
11211 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11213 Fixed bug #787649 by anonymous
11214 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11215 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11217 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11219 Fixed numerous bitfield problems.

11230 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11232 Made the constant following the "interrupt" keyword optional. If
11233 omitted, the function will not automatically be given an entry
11234 in the interrupt vector table (similar to #pragma NOIV, but
11235 less syntacticly kludgy). The interrupt number is also now
11236 range checked. Also fixed a bug in the high order bit example
11243 * support/Util/SDCCerr.c
11244 * support/Util/SDCCerr.h
11247 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11250 * src/SDCCicode.c (operandOperation): rewritten some ops
11251 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11252 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11254 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11255 be re-activated by defining REDUCE_LITERALS)
11256 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11257 unsigned, but are signed by default
11258 * src/SDCCval.c (constVal): rearranged
11259 * src/SDCCval.c (valMod): preliminary fix
11260 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11300 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11301 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11302 constants are unsigned; added recognition of "u" flag for unsigned
11303 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11304 * src/SDCCval.c (valDiv, valMod): fixed signdness
11305 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11306 signedness of modulo, left and right shift

11767 messages from optionsTable when a port is not configured, added
11768 support for the PIc16 port in the ports table, when executing
11769 the compiler with no port specified on command line, a default
11770 port is selected with the new macro DEFAULT_PORT which is
11771 defined in port.h, in setDefaultOptions() linkOptions is removed
11772 from initialization assignment, since now it is a set,
11773 parseCmdLine uses setParseWithComma for linkOptions, in
11774 linkEdit() linkOptions are accessed with new function indexSet()
11775 which returns the i'th item of a set variable. See SDCCset.c, in
11776 linkEdit() when calling buildCmdLine(), added linkOptions as
11777 last argument. Now users can pass arguments to gplink via the
11778 -Wl option, main() uses pic16glue() to glue up pic16 programs

11792 gpasm complaining and test the linkage with gplink, _linkCmd and
11793 _asmCmd changed to be more gplink and gpasm friendly
11794 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11795 produced an error when parsed, peep rule 12 is added to utilize
11796 movff, but it is commented out since the pCode does not support
11797 yet a command with 2 address arguments
11799 2003-05-18 <johan AT balder>

12819 2003-01-07 <johan AT balder>
12821 * src/SDCCast.c (decorateType): fixed bug #600035
12823 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
12824 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12825 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12826 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
12827 * src/pic/pcode.c: outcommented unused variable to remove warnings

12834 2003-01-06 <johan AT balder>
12836 * src/SDCCicode.c: fixed array add
12838 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12839 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12840 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12842 2003-01-04 <johan AT balder>
12844 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12846 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12847 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12849 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12850 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12851 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12853 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12854 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12856 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12857 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12859 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12860 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12862 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12864 * in /sdcc/as/mcs51/ changed these files in order to create an
12865 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12866 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12867 following files to include the previous two files: aslink.dsp,
12868 Makefile.aslink, Makefile.bcc, and Makefile.in.
12870 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12871 .adb instead of .cdb
12873 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12875 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12876 value from option --iram-size.
12878 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12880 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12883 2002-09-18 <wiml AT hhhh.org>
12885 * SDCClrange.h: exposed setFromRange() and setToRange()
12886 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12887 packRegsForAccUse() (bug 542397)
12888 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12889 multiple times and emitting the fetch operations more than once
12890 added aopGetUsesAcc() function to allow binary operators to
12891 fetch their operands in the correct order; made genMinus() emit
12892 compact code for X = LITERAL - Y
12894 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12895 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12896 sprintf() in line 1267.
12898 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12899 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12902 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12903 Changes to aslink (All the changes are marked with 'JCF'):
12905 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12908 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12909 area BSEG. Also moves, if possible, the DATA area down into the internal
12910 ram so more space is available.
12912 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12915 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12916 not bytes. Function summary() which creates a memory usage summary
12917 file with extension .mem. Reports of overlaping stack and small stack
12918 size. If the space for the stack is less than 16 bytes aslink trows a
12921 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12922 the 8051. Option 'y' for memory summary output file.
12924 Changes to sdcc (All the changes are marked with 'JCF'):
12926 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12928 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12929 overlaying area for it (uses RegBankUsed[4]).
12931 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12932 bank zero as used by default. By default aslink locates the stack
12933 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12934 the creation of the .mem file. Delegates the allocation of data area
12935 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12936 the begining of the stack area to aslink.
12938 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12939 glue() in SDCCglue.c creates an area for it.
12941 2002-09-03 Borut Razem <borut.razem AT siol.net>
12942 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12943 sdcc/src/pic/glue.c:
12944 introduced atexit() handler for teporay files removal in case of
12945 errors, assertions, ...
12947 2002-08-29 Borut Razem <borut.razem AT siol.net>
12948 * sdcc/support/cpp2/auto-host_vc_in.h:
12949 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12950 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12951 Maybe there is a similar problem with BORLANDC? It should be checked!
12953 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12954 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12955 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12956 was not executed, and the compiler (cl) launched a warning:
12957 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12959 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12960 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12962 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12963 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12965 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12966 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12967 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12968 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12969 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12970 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12971 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12972 - added Release configuration in VS projects
12973 - review of compiler an linker options
12974 - VC .exe files are generated in bin_vc directory, not to interfere
12975 with binaries generated from other projects (cygwin, mingw, bcc ...)
12977 * sdcc/src/yacc.dsp: added
12979 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12980 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12981 and insert the version number definitions from .version
12983 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12985 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12986 added - genarate auto-host.h using auto-host_vc_in.h as template
12989 removed from CVS, generated automatically
12991 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12992 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12994 2002-08-11 Borut Razem <borut.razem AT siol.net>
12995 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12997 2002-08-10 Borut Razem <borut.razem AT siol.net>
12998 * src/SDCCmain.c (main):
12999 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13000 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13001 The consequence was that some temporary files were not removed.
13004 unification of code in functions tempfilename() and tempfile():
13005 function tempnam() is defined in Visual Studio 6.0 and .NET
13007 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13009 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13010 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13011 - removed compiler command line option /WX: Treats all warnings as errors
13012 - update a list of source files, included into the project
13014 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13015 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13016 changed project type to Generic Project so that can be correcly converted to VS.NET project
13018 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13020 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13022 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13024 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13025 added return 0 statements after assert() to make compiler happy
13027 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13028 added newline in the def file to keep MSC compiler satisfied
13030 * sdcc/src/z80/gen.c:
13031 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13032 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13033 - solved MSC error in function aopDump()
13035 * sdcc_vc.h: define PREFIX as "\\sdcc"
13037 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13038 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13040 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13041 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13042 - Rewrote the register banking algorithm.
13043 - Added pCode live-range analysis to registers (for now, only non-used and
13044 singly-used registers optimized away)
13046 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13048 * 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.

13065 * device/lib/z80/printf.c (sprintf): Added.
13067 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
13069 * src/z80/peeph.def: Added transpose redundent load rule.
13071 * src/z80/main.c: Added force callee saves for jaune.
13073 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13075 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13077 2002-03-28 Johan Knol <johan AT balder>
13079 * src/SDCCval.c: fixed bug #532436
13081 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13083 Added "char *Processor" field to the port structure.
13086 Added -p option. Allows port dependent processor to be specified.
13089 Initialized the new field char *Processor field to NULL in all ports
13092 Compiler generated registers for interrupt context saving
13093 were not getting allocated.
13095 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13098 Fixed left shift. Will promote the left side of a left shift
13099 if a) left shifting more than size of operand or b) when assigned
13100 to something size > size of left side
13102 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13104 tons of changes. Register allocation has been
13105 rewritten. Added customization for the various PICs. Flow
13106 analysis is restructured. ...
13108 * src/pic/device.h:
13111 * src/pic/device.c:
13112 Added. device.c is a PIC port hack to accomodate variations
13115 2002-03-13 Michael Hope <michaelh AT vroom>
13117 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13119 2002-03-04 johanknol <johanknol AT manik>
13121 * /src/SDCCval.c: fixed
13123 const unsigned char arr[][2] = { { 0, 1 } };
13124 t18.c:1: error: Initializer element is not constant

13210 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13212 * sdcc/src/SDCCloop.c:
13213 Previous fix was not good. basic blocks that have "break" or "return" are
13214 not really partof a loop , but live ranges used in these blocks should
13215 be live thru the entire loop, so set partOfLoop but don't add them to
13218 2002-02-21 <johan AT FRIJA>
13220 * src/SDCCcse.c: fixed bug #514308
13222 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13225 Fixed BUG #519583. If a conditional block ended in a return/break
13226 statement inside a loop, it was not being considered part of the loop.
13228 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13230 2002-02-10 Karl Bongers <karl AT turbobit.com>
13233 Fixed up SDCDB debugger somewhat. Updated debugger/README
13234 with lots of comments and notes.
13236 * device/examples/test2.c:
13237 Fix bug, "red" variable not being initialized(compiler complained).
13239 * device/examples/Makefile, examples/test3.c:
13240 Add Makefile in device/examples folder, compiles test3.c
13241 for use as a multiple module SDCDB test case.
13243 * sim/ucsim/cmd.src/cmdset.cc:
13244 Took out debug printfs in ucsim "next" command.
13246 * sim/ucsim/xa.src:
13247 Karl and Johan start ucsim XA support. Most dissassembly working,
13248 about 75% emulation done(plenty of work remaining).
13250 * sim/ucsim/z80.src:
13251 Add Z80 support to ucsim, add test-ucz80 regression test,
13252 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13253 Notice z80 compiler fails on examples/test3.c/crc code.
13255 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13257 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
13258 Added support for --parms-in-bank1
13260 * src/ds390/peeph.def:
13261 added a few more peephole optimzations
