2961 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2963 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2964 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2966 One basic decision: e.g. src/clean.mk includes further files. In order
2967 to make this work there are two solutions:
2968 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2969 run configure on them. This way they can use
2970 'include $(srcdir)/port-clean.mk'
2971 - always include clean.mk by the Makefile at the same level. To avoid
2972 that `make clean` tries to include and build Makefile.dep the
2973 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2974 implemented, because now even `make uninstall` doesn't create
2975 Makefile.in. clean.mk could be eliminated by pasting it in
2978 * debugger/mcs51/Makefile.in: build own objects from library sources
2979 (SLIB, SDCC) in current directory
2981 * configure, configure.in: renamed --disable-device-lib-build in
2982 --disable-device-lib; added --enable-doc, the required tools are
2983 searched by configure; added result message; the toolchain for the
2984 belonging ports are now only built, if the port is enabled.
2986 * support/regression/*: all output is written in directory gen, because
2987 the fwk and ports directories don't livet in the build tree using vpath
2989 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2990 --disable-device-lib, added --enable-doc, added section VPATH
2992 * sim/ucsim/configure.in,
2993 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2994 z80 are enabled by default
2996 2006-04-24 Raphael Neider <rneider AT web.de>
2998 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2999 to config word, "pic14_"-prefixed some extern functions
3000 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3001 config word has been found
3002 * src/pic/device.h: added prototypes
3003 * src/pic/pcode.c: added "pic14_"-prefix where needed
3004 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3006 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3008 (pic14emitRegularMap): ignore config words,
3009 (pic14createInterruptVect): moved generating __config directives away
3010 (picglue): have __config directives emitted
3012 2006-04-24 Borut Razem <borut.razem AT siol.net>
3014 * doc/Makefile: sync with nightly build makefile
3016 2006-04-24 Raphael Neider <rneider AT web.de>
3018 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3019 registers that have not been assigned proper liveranges,
3020 fixes #1469504 and #1474602,
3021 (pCodeRegOptimizeRegUsage): fixed typo in comment
3023 2006-04-24 Borut Razem <borut.razem AT siol.net>
3025 * device/examples/main8051.c: deleted - it was removed from CVS
3026 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3027 after the transition to Subversion
3028 * src/SDCCalloc.h: deleted - it was removed from CVS
3029 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3030 after the transition to Subversion
3031 * sim/ucsim/cpu.gif, sim/ucsim/interrupt.gif, sim/ucsim/new.gif,

3268 interrupts need an interrupt number now if they are made critical),
3269 and enabled nesting of critical functions though not for gbz80
3270 (genCritical, genEndCritical): added functions
3271 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3272 * src/z80/mappings.i: added "ei" to all mappings

3284 the left operand is shorter than the result (c* = lit-c* + int),
3286 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3289 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3291 * src/.version: increased version number to 2.5.5
3292 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3293 linking is done manually in pic16 port's _linkEdit,
3294 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3295 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3296 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3297 allocate asmop as AOP_ACC,
3298 (aopForRemat): added parameter 'bool result' in function declaration,
3299 (pic16_aopGet): return AOP_ACC when accessing WREG,
3300 (pic16_popGetTempReg): minor modification,

3311 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3312 call to allocReg, not by manually allocating a new one,
3313 (pic16_assignRegisters): now before going through the register
3314 allocating functions mark all registers as free. This eliminates some
3315 side effects resulting from peephole parser done earlier in the backbone
3317 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3375 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3376 which dumps before the function entry point a data byte which represents
3377 the number of the local variables used by the specified function, added
3378 'xinst' for initial support for Extended Instruction Support,
3379 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3380 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3381 port->fun_prefix anymore (may change later),
3382 (genFunction, genEndFunction): do not store/restore local registers for
3383 _main (this should take care the --main-return command line option in
3385 (genOr): removed some legacy pic-port instructions,
3386 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3387 performing operations with SFR's causes data to be written more than
3388 once to each SFR. Perhaps SFRs should be handled in special cases...
3389 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3391 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3392 into account for stack starting position,

3394 --extended or -y for Extended Instruction Support,
3395 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3396 (deassignLRs): *** perhaps the most important change, old 'for' code
3397 (commented out for reference), didn't account for some registers which
3398 were left marked 'not free' after a pointer operation. The change
3399 reduces register usage a lot in some cases
3401 2006-03-04 Borut Razem <borut.razem AT siol.net>

5675 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5676 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5677 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5678 always available in leading double underscore form. The C99 support is
5679 mostly missing, but it's a start.
5680 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5681 reserved identifier "__data".

5759 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5761 * device/lib/printf_large.c: removed inline assembly for portability and
5762 readability. Use printf_fast if speed or size are more important.
5763 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5764 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5766 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5768 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5769 prevent compiler warning
5771 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5773 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5774 moved to level 0 and declared as static. Also they are explicit
5775 placed in access bank. This was necessery because some times they
5776 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5777 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5778 optimizations. Currently only compare to unsigned char is implemented,
5779 * src/pic16/gen.c: added fReturnIdx array,
5780 * (struct resolvedIfx) is moved to gen.h and made public,
5781 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5782 * (aopForSym): added an optimization to directly store in stack of
5783 the operand of a SEND iCode,
5784 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5785 but as registers instead (AOP_REG) using the fReturnIdx array,
5786 * (pic16_freeAsmop): remove the freed register from the
5787 _G.sregsAlloc field,
5788 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5789 a compare of 'WREG',
5790 * (pic16_popGetTempRegCond): changed function prototype, now
5791 function takes also a bitVector argument v which holds the current
5792 set of registers that are allocated for stack access by aopForSym,
5793 registers allocated in aopForSym for accessing stack symbols are not
5794 any more part of the functions usedRegs field,
5795 * (genCall): some times aopOp is called for a stack variable to be
5796 send, aopForSym might perform the push, if this is true make sure
5797 that genCall doesn't push the variable twice by testing _G.resDirect,
5798 * (genFunction): changed testing for unspecified interrupt number
5799 from 256 to INTNO_UNSPEC,
5800 * modified selection scheme of frame pointer generation. Previously
5801 if function did use local registers a frame pointer was generated,
5802 now a frame pointer is generated only if function has arguments
5803 (that need PLUSW2 register access), or has stack arguments, or the
5804 compiler is not instructed to omit the frame pointer,
5805 * (genEndFunction): before restoring local registers that were saved
5806 in the function preamble, also restore the registers that *might*
5807 have been allocated for stack access,
5808 * (genRet): removed some old comments,
5809 * (genCmp, the active (RN's) version): added a call to the
5810 pic16_genCmp_special function to perform the compare with a more
5811 robust and optimized way,
5812 * (genInline): a feature has been added in inline code generation,
5813 which allows a wildcard variable substitution when writing inline
5814 assembly. Code is incomplete and experimental therefore undocumented,
5815 * (genCast): changed order of aopOp for result and right to allow
5816 aopForSym to directly load the result if possible,
5817 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5818 perform an optimized compare on some selected special occasions,
5819 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5820 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5821 generate an IVT any more,
5822 * src/pic16/main.c (pic16_optionsTable): added command line option
5824 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5825 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5827 * src/pic16/NOTES: Raphael Neider added in list of active developers
5828 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5829 jumptable_end to prevent bug #,
5830 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5831 inCond and outCond fields,
5832 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5833 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5834 turn off register spilling,
5835 * (packRegsForOneUse): synced with other ports' versions although it
5836 is not used currently,
5837 * (pic16_packRegisters): added an optimization while reading
5838 structure bitfields, some registers may be saved (malloc code is
5839 decreased by 80 bytes)
5841 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5843 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5844 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5845 this can be optimized more?
5847 2005-03-10 Raphael Neider <rneider AT web.de>
5849 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5850 genNearPointerGet): (hopefully) fixed access to bitfields via
5851 pointers (p->bitN = x; and x = p->bitN; failed)
5853 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6485 Adding support for replacing ljmps with sjmps in jumptables
6486 generated for switch statements. For now you need to set the
6487 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6488 Now 4 algorithms for mcs51 jumptable generation are used:
6489 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6490 addresses loaded pc-relative for up to 112 cases and stack-pushing
6491 target addresses loaded with offset from dptr for up to 256 cases.

6518 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6519 to call when a stack overflow occurs,
6520 * (malloc.h): added CVS Id tag,
6521 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6523 * added libc directory. The current version of LibC contains string
6524 functions, ctype functions and macros and some functions of the
6525 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6526 be extensively tested in the future. Standard disclaimer here.
6527 Library is not automatically build yet. But one can build it by
6528 invoking 'make' inside the libc directory.
6529 * added ADC library under libio. Preliminary version yet.
6531 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6538 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6539 * (pic16_storeForReturn): optimized return of 0,
6540 * (genCmp): experimental code for new genCmp which uses PIC18's
6541 special compare&skip instructions. Initial tests fail some times
6542 with variables grater than 1 byte in size, so new code is disabled,
6543 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6545 * (genCast): began a fix to optimize the casting of a bit to another
6546 bit, now assigning a bitfield to another bitfield will fail, sorry,
6547 * src/pic16/main.c: disabled the use of lr-support feature,
6548 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6549 * added some function prototypes, added function _debugf prototype,

6551 bits with offset (case PO_GPR_BIT),
6552 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6554 * (isBankInstruction): modified to return 0 for no banking instruction,
6555 and 1 for banking instruction,
6556 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6557 caused stop processing pCodes after a inline assembly block,
6558 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6559 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6560 registers when it shouldn't,
6561 * src/pic16/ralloc.c (allocReg): add preliminary support for
6562 supporting a limited set of temporary registers,
6564 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6566 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6567 genDataPointerSet): ensure assignments always copy in MSB to LSB
6569 (loadRegFromAop): recognize CLRH optimization,
6570 (genFunction): optimize RECEIVE iCodes in reentrant functions
6572 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6574 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9569 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9571 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9572 loaded with the linker search paths (-L arguments) and the libraries
9573 to be linked with the current source (-l arguments). Changes
9574 currently will affect only the pic16 port.
9575 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9576 include path the port specific paths and port specific libraries,
9577 * gplink command now contains the $3 argument,
9578 * src/pic16/device.h,
9579 * src/pic16/device.c,: structure PIC_device is made public and
9580 renamed to PIC16_device, the same for variable Pics which is renamed

9593 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9595 Documenting changes from previous commits.
9596 * configure.in (version 1.56),
9597 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9598 when generating output files to configure the pic16 library,
9599 but now I've commented it out, since gputils aren't installed in the
9600 SF compile farm, so library won't compile
9602 * device/lib/Makefile.in (version 1.56): initially I've added in
9603 target 'all' the prerequestive 'model-pic16' so it compiled the
9604 pic16 library, but now I've commented it out for the same reasons
9606 * added targets 'model-pic16' and 'objects-pic16' to compile the
9608 * added target 'port-specific-objects-pic16' to handle the
9609 generated libraries and copy them into the build/ directory
9610 * added target 'clean-intermediate-pic16' to clean intermediate
9611 files into pic16 directory
9612 * in target 'installdirs' added line to create directory pic16 in
9613 the installation path
9615 * device/include/Makefile.in (version 1.11): in target 'install'
9616 added lines to copy all header files to installation path,
9617 * in target 'installdirs' added line create directory for pic16
9618 headers in the installation path

9633 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9634 option so that it actually works. Made it specific to the z80, since
9635 the gbz80 doesn't have these kinds of I/O ports.
9637 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9639 * device/include/z180.h,

9652 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9654 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9655 changed interrupt vector table generation to only emit declared vectors.
9656 * device/include/Makefile.in: added missing backslash
9657 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9661 Mainly changes to support compilation of the device libraries
9662 * src/pic16/device.c: stack is allocated via symbol and not
9663 via literal number. The symbol is placed in the corresponding
9664 position of the data ram
9665 * (pic16_dump_section): relocatable and absolute uninitialized
9666 data are now emitted in sorted order to reduce section naming,
9667 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9668 weren't marked as being in the access bank,
9670 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9672 Added portion of GNU PIC Library under the directory
9673 device/include/pic16 and device/lib/pic16. These files
9674 contain the declarations of SFRs for the PIC18Fxx2 devices.
9675 The directory is initialized via configure from toplevel.
9677 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9679 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9680 the spilllocations to be compared correctly
9682 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9684 * src/SDCCast.c (decorateType): fixed bug introduced today
9686 2004-01-12 Borut Razem <borut.razem AT siol.net>
9688 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

9704 * doc/sdccman.lyx: Moved and added some sections, small changes
9705 all over. Telling LaTeX to be less strict with word spacing
9706 to better keep the right margin. Changed some notes about
9707 maintainance of the ports in section 3.2.1 - is it OK like this?
9709 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9746 UPPER for immediate operands,
9747 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9749 * src/pic16/peeph.def: all peepholes with movff are commented out,
9750 because there is a problem in the pcode peep optimizer,
9751 * src/pic16/ralloc.c: the register allocator can now reuse local

9861 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9863 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9864 (default behaviour).
9866 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9868 A python script to validate compiler diagnostic messages. It can be
9869 used to verify that sdcc complains about bad c source code and
9870 gives a good location of the error.
9871 * support/valdiag/Makefile,
9872 * support/valdiag/valdiag.py,
9873 * support/valdiag/tests/*

9890 Bug reported from Jesus Calvino-Fraga
9892 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9894 * sdcc.spec: updated
9895 * device/include/Makefile.in: don't install CVS directories
9896 * device/lib/Makefile.in: added removal of CVS directories after install

9898 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9899 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9900 * src/ds390/gen.c (genRightShift): fixed bug #870788
9901 * src/SDCCast.c (decorateType): fixed bug #870781
9903 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9905 PIC16 port related changes:
9906 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9907 added variable stackPos,
9909 * gen.c: genCall, assignResultValue: added support for
9910 pushing/retrieving function parameters to/from stack,
9911 genFunction,genEndFunction: setup stack frame for the
9913 genAddrOf: will be changed according to bug 863624
9915 * added files genutils.c and genutils.h which contain gen*
9916 debugged and optimised functions extracted from gen.c
9918 * glue.c: added variable 'externs' which holds extern symbols,
9919 pic16emitRegularMap: is modified to properly handle relocatable
9920 symbols under the new scheme,
9921 pic16createInterruptVect: is modified
9922 pic16printPublics: is modified to emit 'global' assembler directives,
9923 added pic16_printExterns to print extern symbols,
9924 pic16glue: initializes stack/frame pointer in the beginning of
9925 the assembly output. Temporary hack, will be corrected later,
9926 because gplink yet does not support stack and SDCC does not
9927 yet support a type of crt0.o object to create the final binary.
9929 * Removed many lines that contain 8051 legacy code.
9930 * The code is finally placed under a 'code' directive.
9931 * Added port specific options.
9933 * _process_pragma: simplified since now we do not need *special*
9934 include file to define SFR registers. But a separate header
9935 will be needed. This will be developed later.
9936 * _pic16_parseOptions: added, parses port specific options:
9937 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9938 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9939 --preplace-udata-with=
9941 * _pic16_setDefaultOptions: modified to initialize section names,
9942 but hack is temporarly out of order since it needs improvement.
9943 * _pic16_genAssemblerPreamble: configuration words are emitted by
9944 their address instead of their name. This part is incomplete and
9945 supports only the 18Fxx2 devices. Other devices will emit an error
9946 during assembly since they do not contain the same set of config
9948 * _pic16_genIVT: is modified,
9950 * pcode.c: added definitions for some hardware registers that are needed
9952 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9953 All PCI entries are updated. Now LFSR is supported.
9954 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9955 * added pic16_newpCodeOpLit2 to support instructions with
9956 two literal arguments
9957 * pic16_pCode2str: corrected code that emits assembler instructions
9958 with two literal operands and those that have an access bit modifier
9959 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9960 this fixes a bug which caused some labels to be lost, when an
9961 assembler directive was added, i.e. banksel,
9962 * pic16_FixRegisterBanking: improved logic that causes the insertion
9964 * InlineFunction: functions that are called once, are not any more
9965 inlined. This can be a port option in the future,
9967 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9969 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9970 hold the corresponding uninitialized symbols,
9971 * pic16_allocProcessorRegister: registers have explicit marked the
9973 * pic16_allocInternalRegister: registers are explicit marked as
9975 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9976 processing list, so bit registers were lost,
9979 * ralloc.h: added field 'accessBank' and original symbol operand
9980 in register definition,
9981 * removed the field isMapped from register definition,
9983 ** Several functions have been removed from various sources:
9984 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9985 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9986 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9987 pic16_assignRelocatableRegisters
9989 ** others have been introduced:
9990 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9991 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9993 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9995 * support/scripts/inc2h.pl: changed definition of BIT_AT
9996 to emit 'sbit at' instead of 'bit at'. This was a request.
9998 PIC16 port related preliminary changes:
9999 * gen.c: prefixed function popRegFromString with
10000 pic16_ and all references to it corrected
10001 * pcode.c: all pic16_pc_* hardware registers prefixed
10002 with underscore (_),
10003 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10004 * ralloc.c: newReg(): when register is REG_SFR then
10005 set address to rIdx,
10006 pic16_allocProcessorRegister(): marks register wasUsed=0
10007 pic16_writeUsedRegs(): added a call to assign processor
10008 registers via pic16_assignFixedRegisters
10010 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10012 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10013 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10014 variables in unused register banks. Also the SSEG is placed
10015 wherever there is enough space for it, and IDATA can be anywhere
10016 in internal RAM. For now compile using -Wl-Y[stack_size].
10017 The mem file is different for this option as well, since it
10018 makes no sense of talking about DSEG lenght.

11006 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11008 * device/lib/_mullong.c: replaced int by short for gcc
11010 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11012 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11013 and JUMPTABLE iCodes properly now (worked by accident before)
11014 * src/mcs51/gen.c (leftRightUseAcc),
11015 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11016 iCode properly now. Use getSize instead of nRegs since a & b
11017 aren't part of the nRegs tally.
11019 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11021 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11031 copied from genNearPointerSet()
11032 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11033 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11034 If they pop r0/r1 they must be called in the opposite order than aopOp().
11035 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11036 (resp. --stack-auto), prepared for --xstack
11038 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11040 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11042 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11047 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11049 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11050 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11051 type for bits was changed. It resulted in bit variables becoming
11052 global, which is not permitted in PIC 14 assembly output.
11054 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11056 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11058 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11060 Z80 and MCS51 linkers complaint if a public symbol is defined
11061 in more than one library module:
11065 * as/mcs51/Makefile.in
11067 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11069 A few small changes that speed up the peephole optimizer.
11073 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11075 Try to make the peephole optimizer smarter by maintaining
11076 an association between the assembly source code and the
11077 iCodes that originated them. Put this information to use
11078 with a new peephole rule condition "notVolatile" so that
11079 the rules can be aggressive yet still safe.
11084 * src/mcs51/peeph.def
11086 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11090 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11091 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11092 if the left or right operand symbols have the accuse flag set.
11094 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11096 Changed the type of the result of the ! (NOT) operator to char;
11097 previously it returned the same type as the source. This allows
11098 us to eliminate all the genFloatNot functions (all of its target
11099 implementations were very buggy) since !float can use the same
11102 * src/SDCCicode.c (ast2iCode): ! returns char
11103 * src/mcs51/gen.c (genNot, genNotFloat),
11104 * src/ds390/gen.c (genNot, genNotFloat),
11105 * src/z80/gen.c (genNot, genNotFloat),
11106 * src/pic/gen.c (genNot, genNotFloat),
11107 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11109 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11111 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11112 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11113 during interrupts. Ensure WSAVE is located at a shared bank address.
11114 2. Fixed page selection in some places
11115 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11116 the registers name strings.
11117 4. Fixed "signed / unsigned compare" compiler warnings.
11118 5. The PIC port manages its own allocation of the general purpose
11119 registers, but makes no attempt to reuse them. As a result when
11120 compiling it soon runs out of general purpose registers. Some
11121 additional code was added to the files pcode.c and device.c to walk
11122 through the function call tree and rename the registers so that they
11132 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11133 genPlus() & genMinus() when the result is the same as left or right
11135 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11139 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11141 Made bitfield a distinct type from bit so that bitfields
11142 convert as per ANSI C and bits retain their traditional
11143 boolean style behaviour. Implemented bitfield support in
11151 * src/ds390/gen.c: bit v bitfield split
11152 * src/z80/gen.c: New support for bitfields
11153 * support/regression/tests/bitfields.c: reenabled z80,
11156 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11158 Rules 246.x, 247.x relate to bitfields, the others speed up
11159 access to xdata mapped I/O devices.
11161 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11163 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11165 Cleaned up genPackBits and genUnpackBits and added two helper
11166 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11167 for literal assignments in genPackBits (thanks to Frieder for
11173 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11175 Fixed bug #748310 (pointer to function type mishandled when the
11176 function name is omitted). Also fixed a SIGSEGV when a function
11177 attribute (reentrant, etc) is used on a non-function or on a
11178 function but misplaced before the parameter list.
11180 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11182 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11183 * support/Util/SDCCerr.h,
11184 * support/Util/SDCCerr.c: Added func attr misuse error msg
11186 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11188 Fixed bug #787649 by anonymous
11189 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11190 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11192 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11194 Fixed numerous bitfield problems.

11205 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11207 Made the constant following the "interrupt" keyword optional. If
11208 omitted, the function will not automatically be given an entry
11209 in the interrupt vector table (similar to #pragma NOIV, but
11210 less syntacticly kludgy). The interrupt number is also now
11211 range checked. Also fixed a bug in the high order bit example
11218 * support/Util/SDCCerr.c
11219 * support/Util/SDCCerr.h
11222 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11225 * src/SDCCicode.c (operandOperation): rewritten some ops
11226 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11227 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11229 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11230 be re-activated by defining REDUCE_LITERALS)
11231 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11232 unsigned, but are signed by default
11233 * src/SDCCval.c (constVal): rearranged
11234 * src/SDCCval.c (valMod): preliminary fix
11235 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11275 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11276 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11277 constants are unsigned; added recognition of "u" flag for unsigned
11278 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11279 * src/SDCCval.c (valDiv, valMod): fixed signdness

11741 added if/endif conditional macros to remove options help
11742 messages from optionsTable when a port is not configured, added
11743 support for the PIc16 port in the ports table, when executing
11744 the compiler with no port specified on command line, a default
11745 port is selected with the new macro DEFAULT_PORT which is
11746 defined in port.h, in setDefaultOptions() linkOptions is removed
11747 from initialization assignment, since now it is a set,
11748 parseCmdLine uses setParseWithComma for linkOptions, in
11749 linkEdit() linkOptions are accessed with new function indexSet()
11750 which returns the i'th item of a set variable. See SDCCset.c, in
11751 linkEdit() when calling buildCmdLine(), added linkOptions as
11752 last argument. Now users can pass arguments to gplink via the
11753 -Wl option, main() uses pic16glue() to glue up pic16 programs

11767 gpasm complaining and test the linkage with gplink, _linkCmd and
11768 _asmCmd changed to be more gplink and gpasm friendly
11769 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11770 produced an error when parsed, peep rule 12 is added to utilize
11771 movff, but it is commented out since the pCode does not support
11772 yet a command with 2 address arguments
11774 2003-05-18 <johan AT balder>
11776 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12799 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12800 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12801 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
12802 * src/pic/pcode.c: outcommented unused variable to remove warnings
12803 * src/pic/ralloc.c: outcommented unused variable to remove warnings
12805 2003-01-06 <karl AT turbobit.com>
12806 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
12809 2003-01-06 <johan AT balder>
12811 * src/SDCCicode.c: fixed array add
12813 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12814 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12815 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12817 2003-01-04 <johan AT balder>
12819 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12821 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12822 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12824 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12825 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12826 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12828 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12829 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12831 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12832 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12834 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12835 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12837 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12839 * in /sdcc/as/mcs51/ changed these files in order to create an
12840 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12841 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12842 following files to include the previous two files: aslink.dsp,
12843 Makefile.aslink, Makefile.bcc, and Makefile.in.
12845 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12846 .adb instead of .cdb
12848 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12850 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12851 value from option --iram-size.
12853 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12855 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12858 2002-09-18 <wiml AT hhhh.org>
12860 * SDCClrange.h: exposed setFromRange() and setToRange()
12861 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12862 packRegsForAccUse() (bug 542397)
12863 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12864 multiple times and emitting the fetch operations more than once
12865 added aopGetUsesAcc() function to allow binary operators to
12866 fetch their operands in the correct order; made genMinus() emit
12867 compact code for X = LITERAL - Y
12869 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12870 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12871 sprintf() in line 1267.
12873 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12874 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12877 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12878 Changes to aslink (All the changes are marked with 'JCF'):
12880 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12883 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12884 area BSEG. Also moves, if possible, the DATA area down into the internal
12885 ram so more space is available.
12887 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12890 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12891 not bytes. Function summary() which creates a memory usage summary
12892 file with extension .mem. Reports of overlaping stack and small stack
12893 size. If the space for the stack is less than 16 bytes aslink trows a
12896 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12897 the 8051. Option 'y' for memory summary output file.
12899 Changes to sdcc (All the changes are marked with 'JCF'):
12901 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12903 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12904 overlaying area for it (uses RegBankUsed[4]).
12906 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12907 bank zero as used by default. By default aslink locates the stack
12908 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12909 the creation of the .mem file. Delegates the allocation of data area
12910 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12911 the begining of the stack area to aslink.
12913 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12914 glue() in SDCCglue.c creates an area for it.
12916 2002-09-03 Borut Razem <borut.razem AT siol.net>
12917 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12918 sdcc/src/pic/glue.c:
12919 introduced atexit() handler for teporay files removal in case of
12920 errors, assertions, ...
12922 2002-08-29 Borut Razem <borut.razem AT siol.net>
12923 * sdcc/support/cpp2/auto-host_vc_in.h:
12924 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12925 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12926 Maybe there is a similar problem with BORLANDC? It should be checked!
12928 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12929 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12930 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12931 was not executed, and the compiler (cl) launched a warning:
12932 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12934 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12935 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12937 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12938 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12940 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12941 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12942 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12943 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12944 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12945 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12946 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12947 - added Release configuration in VS projects
12948 - review of compiler an linker options
12949 - VC .exe files are generated in bin_vc directory, not to interfere
12950 with binaries generated from other projects (cygwin, mingw, bcc ...)
12952 * sdcc/src/yacc.dsp: added
12954 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12955 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12956 and insert the version number definitions from .version
12958 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12960 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12961 added - genarate auto-host.h using auto-host_vc_in.h as template
12964 removed from CVS, generated automatically
12966 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12967 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12969 2002-08-11 Borut Razem <borut.razem AT siol.net>
12970 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12972 2002-08-10 Borut Razem <borut.razem AT siol.net>
12973 * src/SDCCmain.c (main):
12974 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12975 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12976 The consequence was that some temporary files were not removed.
12979 unification of code in functions tempfilename() and tempfile():
12980 function tempnam() is defined in Visual Studio 6.0 and .NET
12982 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12984 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12985 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12986 - removed compiler command line option /WX: Treats all warnings as errors
12987 - update a list of source files, included into the project
12989 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12990 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12991 changed project type to Generic Project so that can be correcly converted to VS.NET project
12993 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12995 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12997 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12999 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13000 added return 0 statements after assert() to make compiler happy
13002 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13003 added newline in the def file to keep MSC compiler satisfied
13005 * sdcc/src/z80/gen.c:
13006 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13007 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13008 - solved MSC error in function aopDump()
13010 * sdcc_vc.h: define PREFIX as "\\sdcc"
13012 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13013 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13015 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13016 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13017 - Rewrote the register banking algorithm.
13018 - Added pCode live-range analysis to registers (for now, only non-used and
13019 singly-used registers optimized away)
13021 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13023 * 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.

13046 * src/z80/main.c: Added force callee saves for jaune.
13048 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13050 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13052 2002-03-28 Johan Knol <johan AT balder>
13054 * src/SDCCval.c: fixed bug #532436
13056 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13058 Added "char *Processor" field to the port structure.
13061 Added -p option. Allows port dependent processor to be specified.
13064 Initialized the new field char *Processor field to NULL in all ports
13067 Compiler generated registers for interrupt context saving
13068 were not getting allocated.
13070 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13073 Fixed left shift. Will promote the left side of a left shift
13074 if a) left shifting more than size of operand or b) when assigned
13075 to something size > size of left side
13077 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13079 tons of changes. Register allocation has been
13080 rewritten. Added customization for the various PICs. Flow
13081 analysis is restructured. ...
13083 * src/pic/device.h:
13086 * src/pic/device.c:
13087 Added. device.c is a PIC port hack to accomodate variations
13090 2002-03-13 Michael Hope <michaelh AT vroom>
13092 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13094 2002-03-04 johanknol <johanknol AT manik>
13096 * /src/SDCCval.c: fixed
13098 const unsigned char arr[][2] = { { 0, 1 } };
13099 t18.c:1: error: Initializer element is not constant

13185 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13187 * sdcc/src/SDCCloop.c:
13188 Previous fix was not good. basic blocks that have "break" or "return" are
13189 not really partof a loop , but live ranges used in these blocks should
13190 be live thru the entire loop, so set partOfLoop but don't add them to
13193 2002-02-21 <johan AT FRIJA>
13195 * src/SDCCcse.c: fixed bug #514308
13197 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13200 Fixed BUG #519583. If a conditional block ended in a return/break
13201 statement inside a loop, it was not being considered part of the loop.
13203 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13205 2002-02-10 Karl Bongers <karl AT turbobit.com>

13209 with lots of comments and notes.
13211 * device/examples/test2.c:
13212 Fix bug, "red" variable not being initialized(compiler complained).
13214 * device/examples/Makefile, examples/test3.c:
13215 Add Makefile in device/examples folder, compiles test3.c
13216 for use as a multiple module SDCDB test case.
13218 * sim/ucsim/cmd.src/cmdset.cc:
13219 Took out debug printfs in ucsim "next" command.
13221 * sim/ucsim/xa.src:
13222 Karl and Johan start ucsim XA support. Most dissassembly working,
13223 about 75% emulation done(plenty of work remaining).
13225 * sim/ucsim/z80.src:
13226 Add Z80 support to ucsim, add test-ucz80 regression test,
13227 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13228 Notice z80 compiler fails on examples/test3.c/crc code.
13230 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13232 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

13240 from a memory mapped port
13241 2) added __builtin_memcmp
13242 3) added __builtin_swapw swap bytes of a short
13244 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13245 1) handle multiple send & receives from register bank1
13246 2) ralloc can now allocate DPTR1 to some liveRanges
13248 * src/SDCCsymt.c, src/SDCCsymt.h:
13249 changes to handle multiple sends & receives
13251 * src/SDCCptropt.h:
13252 added some pointer arithmetic optimization
13254 * src/SDCCptropt.c:
13255 added some pointer arithmetic optimizations but not stable yet so not
13256 called from anywhere (will get this working shortly)
13258 * src/SDCCopt.c: fixed for multiple sends & receives
13261 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
13262 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
13263 set preprocessor defines (depending on options)
13265 * src/SDCCicode.c, src/SDCCicode.h:
13266 changes made to handle multiple sends & receives
13269 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
