2959 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2961 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2962 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2964 One basic decision: e.g. src/clean.mk includes further files. In order
2965 to make this work there are two solutions:
2966 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2967 run configure on them. This way they can use
2968 'include $(srcdir)/port-clean.mk'
2969 - always include clean.mk by the Makefile at the same level. To avoid
2970 that `make clean` tries to include and build Makefile.dep the
2971 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2972 implemented, because now even `make uninstall` doesn't create
2973 Makefile.in. clean.mk could be eliminated by pasting it in
2976 * debugger/mcs51/Makefile.in: build own objects from library sources
2977 (SLIB, SDCC) in current directory
2979 * configure, configure.in: renamed --disable-device-lib-build in
2980 --disable-device-lib; added --enable-doc, the required tools are
2981 searched by configure; added result message; the toolchain for the
2982 belonging ports are now only built, if the port is enabled.
2984 * support/regression/*: all output is written in directory gen, because
2985 the fwk and ports directories don't livet in the build tree using vpath
2987 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2988 --disable-device-lib, added --enable-doc, added section VPATH
2990 * sim/ucsim/configure.in,
2991 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2992 z80 are enabled by default
2994 2006-04-24 Raphael Neider <rneider AT web.de>
2996 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2997 to config word, "pic14_"-prefixed some extern functions
2998 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2999 config word has been found
3000 * src/pic/device.h: added prototypes
3001 * src/pic/pcode.c: added "pic14_"-prefix where needed
3002 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3004 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3006 (pic14emitRegularMap): ignore config words,
3007 (pic14createInterruptVect): moved generating __config directives away
3008 (picglue): have __config directives emitted
3010 2006-04-24 Borut Razem <borut.razem AT siol.net>
3012 * doc/Makefile: sync with nightly build makefile
3014 2006-04-24 Raphael Neider <rneider AT web.de>
3016 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3017 registers that have not been assigned proper liveranges,
3018 fixes #1469504 and #1474602,
3019 (pCodeRegOptimizeRegUsage): fixed typo in comment
3021 2006-04-24 Borut Razem <borut.razem AT siol.net>
3023 * device/examples/main8051.c: deleted - it was removed from CVS
3024 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3025 after the transition to Subversion
3026 * src/SDCCalloc.h: deleted - it was removed from CVS
3027 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3028 after the transition to Subversion
3029 * sim/ucsim/cpu.gif, sim/ucsim/interrupt.gif, sim/ucsim/new.gif,

3267 and enabled nesting of critical functions though not for gbz80
3268 (genCritical, genEndCritical): added functions
3269 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3270 * src/z80/mappings.i: added "ei" to all mappings

3282 the left operand is shorter than the result (c* = lit-c* + int),
3284 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3287 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3289 * src/.version: increased version number to 2.5.5
3290 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3291 linking is done manually in pic16 port's _linkEdit,
3292 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3293 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3294 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3295 allocate asmop as AOP_ACC,
3296 (aopForRemat): added parameter 'bool result' in function declaration,
3297 (pic16_aopGet): return AOP_ACC when accessing WREG,
3298 (pic16_popGetTempReg): minor modification,

3309 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3310 call to allocReg, not by manually allocating a new one,
3311 (pic16_assignRegisters): now before going through the register
3312 allocating functions mark all registers as free. This eliminates some
3313 side effects resulting from peephole parser done earlier in the backbone
3315 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3373 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3374 which dumps before the function entry point a data byte which represents
3375 the number of the local variables used by the specified function, added
3376 'xinst' for initial support for Extended Instruction Support,
3377 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3378 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3379 port->fun_prefix anymore (may change later),
3380 (genFunction, genEndFunction): do not store/restore local registers for
3381 _main (this should take care the --main-return command line option in
3383 (genOr): removed some legacy pic-port instructions,
3384 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3385 performing operations with SFR's causes data to be written more than
3386 once to each SFR. Perhaps SFRs should be handled in special cases...
3387 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3389 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3390 into account for stack starting position,

3394 (deassignLRs): *** perhaps the most important change, old 'for' code
3395 (commented out for reference), didn't account for some registers which
3396 were left marked 'not free' after a pointer operation. The change
3397 reduces register usage a lot in some cases
3399 2006-03-04 Borut Razem <borut.razem AT siol.net>

5673 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5674 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5675 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5676 always available in leading double underscore form. The C99 support is
5677 mostly missing, but it's a start.
5678 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5679 reserved identifier "__data".

5757 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5759 * device/lib/printf_large.c: removed inline assembly for portability and
5760 readability. Use printf_fast if speed or size are more important.
5761 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5762 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5764 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5766 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5767 prevent compiler warning
5769 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5771 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5772 moved to level 0 and declared as static. Also they are explicit
5773 placed in access bank. This was necessery because some times they
5774 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5775 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5776 optimizations. Currently only compare to unsigned char is implemented,
5777 * src/pic16/gen.c: added fReturnIdx array,
5778 * (struct resolvedIfx) is moved to gen.h and made public,
5779 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5780 * (aopForSym): added an optimization to directly store in stack of
5781 the operand of a SEND iCode,
5782 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5783 but as registers instead (AOP_REG) using the fReturnIdx array,
5784 * (pic16_freeAsmop): remove the freed register from the
5785 _G.sregsAlloc field,
5786 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5787 a compare of 'WREG',
5788 * (pic16_popGetTempRegCond): changed function prototype, now
5789 function takes also a bitVector argument v which holds the current
5790 set of registers that are allocated for stack access by aopForSym,
5791 registers allocated in aopForSym for accessing stack symbols are not
5792 any more part of the functions usedRegs field,
5793 * (genCall): some times aopOp is called for a stack variable to be
5794 send, aopForSym might perform the push, if this is true make sure
5795 that genCall doesn't push the variable twice by testing _G.resDirect,
5796 * (genFunction): changed testing for unspecified interrupt number
5797 from 256 to INTNO_UNSPEC,
5798 * modified selection scheme of frame pointer generation. Previously
5799 if function did use local registers a frame pointer was generated,
5800 now a frame pointer is generated only if function has arguments
5801 (that need PLUSW2 register access), or has stack arguments, or the
5802 compiler is not instructed to omit the frame pointer,
5803 * (genEndFunction): before restoring local registers that were saved
5804 in the function preamble, also restore the registers that *might*
5805 have been allocated for stack access,
5806 * (genRet): removed some old comments,
5807 * (genCmp, the active (RN's) version): added a call to the
5808 pic16_genCmp_special function to perform the compare with a more
5809 robust and optimized way,
5810 * (genInline): a feature has been added in inline code generation,
5811 which allows a wildcard variable substitution when writing inline
5812 assembly. Code is incomplete and experimental therefore undocumented,
5813 * (genCast): changed order of aopOp for result and right to allow
5814 aopForSym to directly load the result if possible,
5815 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5816 perform an optimized compare on some selected special occasions,
5817 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5818 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5819 generate an IVT any more,
5820 * src/pic16/main.c (pic16_optionsTable): added command line option
5822 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5823 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5825 * src/pic16/NOTES: Raphael Neider added in list of active developers
5826 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5827 jumptable_end to prevent bug #,
5828 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5829 inCond and outCond fields,
5830 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5831 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5832 turn off register spilling,
5833 * (packRegsForOneUse): synced with other ports' versions although it
5834 is not used currently,
5835 * (pic16_packRegisters): added an optimization while reading
5836 structure bitfields, some registers may be saved (malloc code is
5837 decreased by 80 bytes)
5839 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5841 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5842 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5843 this can be optimized more?
5845 2005-03-10 Raphael Neider <rneider AT web.de>
5847 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5848 genNearPointerGet): (hopefully) fixed access to bitfields via
5849 pointers (p->bitN = x; and x = p->bitN; failed)
5851 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6481 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6483 Adding support for replacing ljmps with sjmps in jumptables
6484 generated for switch statements. For now you need to set the
6485 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6486 Now 4 algorithms for mcs51 jumptable generation are used:
6487 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6488 addresses loaded pc-relative for up to 112 cases and stack-pushing
6489 target addresses loaded with offset from dptr for up to 256 cases.
6491 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6492 * src/mcs51/main.c: adapted constants for switch table generation

6516 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6517 to call when a stack overflow occurs,
6518 * (malloc.h): added CVS Id tag,
6519 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6521 * added libc directory. The current version of LibC contains string
6522 functions, ctype functions and macros and some functions of the
6523 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6524 be extensively tested in the future. Standard disclaimer here.
6525 Library is not automatically build yet. But one can build it by
6526 invoking 'make' inside the libc directory.
6527 * added ADC library under libio. Preliminary version yet.
6529 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6536 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6537 * (pic16_storeForReturn): optimized return of 0,
6538 * (genCmp): experimental code for new genCmp which uses PIC18's
6539 special compare&skip instructions. Initial tests fail some times
6540 with variables grater than 1 byte in size, so new code is disabled,
6541 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6543 * (genCast): began a fix to optimize the casting of a bit to another
6544 bit, now assigning a bitfield to another bitfield will fail, sorry,
6545 * src/pic16/main.c: disabled the use of lr-support feature,
6546 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6547 * added some function prototypes, added function _debugf prototype,

6549 bits with offset (case PO_GPR_BIT),
6550 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6552 * (isBankInstruction): modified to return 0 for no banking instruction,
6553 and 1 for banking instruction,
6554 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6555 caused stop processing pCodes after a inline assembly block,
6556 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6557 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6558 registers when it shouldn't,
6559 * src/pic16/ralloc.c (allocReg): add preliminary support for
6560 supporting a limited set of temporary registers,
6562 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6564 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6565 genDataPointerSet): ensure assignments always copy in MSB to LSB
6567 (loadRegFromAop): recognize CLRH optimization,
6568 (genFunction): optimize RECEIVE iCodes in reentrant functions
6570 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6572 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9567 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9569 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9570 loaded with the linker search paths (-L arguments) and the libraries
9571 to be linked with the current source (-l arguments). Changes
9572 currently will affect only the pic16 port.
9573 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9574 include path the port specific paths and port specific libraries,
9575 * gplink command now contains the $3 argument,
9576 * src/pic16/device.h,
9577 * src/pic16/device.c,: structure PIC_device is made public and
9578 renamed to PIC16_device, the same for variable Pics which is renamed

9591 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9593 Documenting changes from previous commits.
9594 * configure.in (version 1.56),
9595 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9596 when generating output files to configure the pic16 library,
9597 but now I've commented it out, since gputils aren't installed in the
9598 SF compile farm, so library won't compile
9600 * device/lib/Makefile.in (version 1.56): initially I've added in
9601 target 'all' the prerequestive 'model-pic16' so it compiled the
9602 pic16 library, but now I've commented it out for the same reasons
9604 * added targets 'model-pic16' and 'objects-pic16' to compile the
9606 * added target 'port-specific-objects-pic16' to handle the
9607 generated libraries and copy them into the build/ directory
9608 * added target 'clean-intermediate-pic16' to clean intermediate
9609 files into pic16 directory
9610 * in target 'installdirs' added line to create directory pic16 in
9611 the installation path
9613 * device/include/Makefile.in (version 1.11): in target 'install'
9614 added lines to copy all header files to installation path,
9615 * in target 'installdirs' added line create directory for pic16
9616 headers in the installation path

9631 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9632 option so that it actually works. Made it specific to the z80, since
9633 the gbz80 doesn't have these kinds of I/O ports.
9635 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9637 * device/include/z180.h,

9650 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9652 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9653 changed interrupt vector table generation to only emit declared vectors.
9654 * device/include/Makefile.in: added missing backslash
9655 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9659 Mainly changes to support compilation of the device libraries
9660 * src/pic16/device.c: stack is allocated via symbol and not
9661 via literal number. The symbol is placed in the corresponding
9662 position of the data ram
9663 * (pic16_dump_section): relocatable and absolute uninitialized
9664 data are now emitted in sorted order to reduce section naming,
9665 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9666 weren't marked as being in the access bank,
9668 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9670 Added portion of GNU PIC Library under the directory
9671 device/include/pic16 and device/lib/pic16. These files
9672 contain the declarations of SFRs for the PIC18Fxx2 devices.
9673 The directory is initialized via configure from toplevel.
9675 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9677 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9678 the spilllocations to be compared correctly
9680 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9682 * src/SDCCast.c (decorateType): fixed bug introduced today
9684 2004-01-12 Borut Razem <borut.razem AT siol.net>
9686 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

9702 * doc/sdccman.lyx: Moved and added some sections, small changes
9703 all over. Telling LaTeX to be less strict with word spacing
9704 to better keep the right margin. Changed some notes about
9705 maintainance of the ports in section 3.2.1 - is it OK like this?
9707 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9744 UPPER for immediate operands,
9745 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9747 * src/pic16/peeph.def: all peepholes with movff are commented out,
9748 because there is a problem in the pcode peep optimizer,
9749 * src/pic16/ralloc.c: the register allocator can now reuse local

9814 directive when no overlay data exist
9815 * (picglue): modified to emit uninitialized data segment
9816 according to udata_section_name

9859 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9861 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9862 (default behaviour).
9864 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9866 A python script to validate compiler diagnostic messages. It can be
9867 used to verify that sdcc complains about bad c source code and
9868 gives a good location of the error.
9869 * support/valdiag/Makefile,
9870 * support/valdiag/valdiag.py,
9871 * support/valdiag/tests/*
9873 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9888 Bug reported from Jesus Calvino-Fraga
9890 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9892 * sdcc.spec: updated
9893 * device/include/Makefile.in: don't install CVS directories
9894 * device/lib/Makefile.in: added removal of CVS directories after install

9896 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9897 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9898 * src/ds390/gen.c (genRightShift): fixed bug #870788
9899 * src/SDCCast.c (decorateType): fixed bug #870781
9901 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9903 PIC16 port related changes:
9904 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9905 added variable stackPos,
9907 * gen.c: genCall, assignResultValue: added support for
9908 pushing/retrieving function parameters to/from stack,
9909 genFunction,genEndFunction: setup stack frame for the
9911 genAddrOf: will be changed according to bug 863624
9913 * added files genutils.c and genutils.h which contain gen*
9914 debugged and optimised functions extracted from gen.c
9916 * glue.c: added variable 'externs' which holds extern symbols,
9917 pic16emitRegularMap: is modified to properly handle relocatable
9918 symbols under the new scheme,
9919 pic16createInterruptVect: is modified
9920 pic16printPublics: is modified to emit 'global' assembler directives,
9921 added pic16_printExterns to print extern symbols,
9922 pic16glue: initializes stack/frame pointer in the beginning of
9923 the assembly output. Temporary hack, will be corrected later,
9924 because gplink yet does not support stack and SDCC does not
9925 yet support a type of crt0.o object to create the final binary.
9927 * Removed many lines that contain 8051 legacy code.
9928 * The code is finally placed under a 'code' directive.
9929 * Added port specific options.
9931 * _process_pragma: simplified since now we do not need *special*
9932 include file to define SFR registers. But a separate header
9933 will be needed. This will be developed later.
9934 * _pic16_parseOptions: added, parses port specific options:
9935 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9936 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9937 --preplace-udata-with=
9939 * _pic16_setDefaultOptions: modified to initialize section names,
9940 but hack is temporarly out of order since it needs improvement.
9941 * _pic16_genAssemblerPreamble: configuration words are emitted by
9942 their address instead of their name. This part is incomplete and
9943 supports only the 18Fxx2 devices. Other devices will emit an error
9944 during assembly since they do not contain the same set of config
9946 * _pic16_genIVT: is modified,
9948 * pcode.c: added definitions for some hardware registers that are needed
9950 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9951 All PCI entries are updated. Now LFSR is supported.
9952 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9953 * added pic16_newpCodeOpLit2 to support instructions with
9954 two literal arguments
9955 * pic16_pCode2str: corrected code that emits assembler instructions
9956 with two literal operands and those that have an access bit modifier
9957 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9958 this fixes a bug which caused some labels to be lost, when an
9959 assembler directive was added, i.e. banksel,
9960 * pic16_FixRegisterBanking: improved logic that causes the insertion
9962 * InlineFunction: functions that are called once, are not any more
9963 inlined. This can be a port option in the future,
9965 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9967 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9968 hold the corresponding uninitialized symbols,
9969 * pic16_allocProcessorRegister: registers have explicit marked the
9971 * pic16_allocInternalRegister: registers are explicit marked as
9973 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9974 processing list, so bit registers were lost,
9977 * ralloc.h: added field 'accessBank' and original symbol operand
9978 in register definition,
9979 * removed the field isMapped from register definition,
9981 ** Several functions have been removed from various sources:
9982 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9983 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9984 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9985 pic16_assignRelocatableRegisters
9987 ** others have been introduced:
9988 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9989 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9991 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9993 * support/scripts/inc2h.pl: changed definition of BIT_AT
9994 to emit 'sbit at' instead of 'bit at'. This was a request.
9996 PIC16 port related preliminary changes:
9997 * gen.c: prefixed function popRegFromString with
9998 pic16_ and all references to it corrected
9999 * pcode.c: all pic16_pc_* hardware registers prefixed
10000 with underscore (_),
10001 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10002 * ralloc.c: newReg(): when register is REG_SFR then
10003 set address to rIdx,
10004 pic16_allocProcessorRegister(): marks register wasUsed=0
10005 pic16_writeUsedRegs(): added a call to assign processor
10006 registers via pic16_assignFixedRegisters
10008 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10010 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10011 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10012 variables in unused register banks. Also the SSEG is placed
10013 wherever there is enough space for it, and IDATA can be anywhere
10014 in internal RAM. For now compile using -Wl-Y[stack_size].
10015 The mem file is different for this option as well, since it
10016 makes no sense of talking about DSEG lenght.

11004 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11006 * device/lib/_mullong.c: replaced int by short for gcc
11008 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11010 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11011 and JUMPTABLE iCodes properly now (worked by accident before)
11012 * src/mcs51/gen.c (leftRightUseAcc),
11013 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11014 iCode properly now. Use getSize instead of nRegs since a & b
11015 aren't part of the nRegs tally.
11017 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11019 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11029 copied from genNearPointerSet()
11030 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11031 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11032 If they pop r0/r1 they must be called in the opposite order than aopOp().
11033 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11034 (resp. --stack-auto), prepared for --xstack
11036 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11038 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11040 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11045 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11047 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11048 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11049 type for bits was changed. It resulted in bit variables becoming
11050 global, which is not permitted in PIC 14 assembly output.
11052 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11054 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11056 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11058 Z80 and MCS51 linkers complaint if a public symbol is defined
11059 in more than one library module:
11063 * as/mcs51/Makefile.in
11065 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11067 A few small changes that speed up the peephole optimizer.
11071 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11073 Try to make the peephole optimizer smarter by maintaining
11074 an association between the assembly source code and the
11075 iCodes that originated them. Put this information to use
11076 with a new peephole rule condition "notVolatile" so that
11077 the rules can be aggressive yet still safe.
11082 * src/mcs51/peeph.def
11084 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11088 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11089 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11090 if the left or right operand symbols have the accuse flag set.
11092 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11094 Changed the type of the result of the ! (NOT) operator to char;
11095 previously it returned the same type as the source. This allows
11096 us to eliminate all the genFloatNot functions (all of its target
11097 implementations were very buggy) since !float can use the same
11100 * src/SDCCicode.c (ast2iCode): ! returns char
11101 * src/mcs51/gen.c (genNot, genNotFloat),
11102 * src/ds390/gen.c (genNot, genNotFloat),
11103 * src/z80/gen.c (genNot, genNotFloat),
11104 * src/pic/gen.c (genNot, genNotFloat),
11105 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11109 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11110 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11111 during interrupts. Ensure WSAVE is located at a shared bank address.
11112 2. Fixed page selection in some places
11113 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11114 the registers name strings.
11115 4. Fixed "signed / unsigned compare" compiler warnings.
11116 5. The PIC port manages its own allocation of the general purpose
11117 registers, but makes no attempt to reuse them. As a result when
11118 compiling it soon runs out of general purpose registers. Some
11119 additional code was added to the files pcode.c and device.c to walk
11120 through the function call tree and rename the registers so that they
11130 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11131 genPlus() & genMinus() when the result is the same as left or right
11133 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11137 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11139 Made bitfield a distinct type from bit so that bitfields
11140 convert as per ANSI C and bits retain their traditional
11141 boolean style behaviour. Implemented bitfield support in
11149 * src/ds390/gen.c: bit v bitfield split
11150 * src/z80/gen.c: New support for bitfields
11151 * support/regression/tests/bitfields.c: reenabled z80,
11154 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11156 Rules 246.x, 247.x relate to bitfields, the others speed up
11157 access to xdata mapped I/O devices.
11159 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11161 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11163 Cleaned up genPackBits and genUnpackBits and added two helper
11164 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11165 for literal assignments in genPackBits (thanks to Frieder for
11171 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11173 Fixed bug #748310 (pointer to function type mishandled when the
11174 function name is omitted). Also fixed a SIGSEGV when a function
11175 attribute (reentrant, etc) is used on a non-function or on a
11176 function but misplaced before the parameter list.
11178 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11180 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11181 * support/Util/SDCCerr.h,
11182 * support/Util/SDCCerr.c: Added func attr misuse error msg
11184 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11186 Fixed bug #787649 by anonymous
11187 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11188 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11190 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11203 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11205 Made the constant following the "interrupt" keyword optional. If
11206 omitted, the function will not automatically be given an entry
11207 in the interrupt vector table (similar to #pragma NOIV, but
11208 less syntacticly kludgy). The interrupt number is also now
11209 range checked. Also fixed a bug in the high order bit example
11216 * support/Util/SDCCerr.c
11217 * support/Util/SDCCerr.h
11220 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11225 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11227 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11228 be re-activated by defining REDUCE_LITERALS)
11229 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11230 unsigned, but are signed by default
11231 * src/SDCCval.c (constVal): rearranged
11232 * src/SDCCval.c (valMod): preliminary fix
11233 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11273 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11274 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11275 constants are unsigned; added recognition of "u" flag for unsigned
11276 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11277 * src/SDCCval.c (valDiv, valMod): fixed signdness

11686 the regression tests I'm not brave enough to enable 245.b, 245.c
11687 * doc/sdccman.lyx: added latex preamble for hyperref package.
11688 Using pdflatex this will give you a hyperlinked pdf file with

11739 added if/endif conditional macros to remove options help
11740 messages from optionsTable when a port is not configured, added
11741 support for the PIc16 port in the ports table, when executing
11742 the compiler with no port specified on command line, a default
11743 port is selected with the new macro DEFAULT_PORT which is
11744 defined in port.h, in setDefaultOptions() linkOptions is removed
11745 from initialization assignment, since now it is a set,
11746 parseCmdLine uses setParseWithComma for linkOptions, in
11747 linkEdit() linkOptions are accessed with new function indexSet()
11748 which returns the i'th item of a set variable. See SDCCset.c, in
11749 linkEdit() when calling buildCmdLine(), added linkOptions as
11750 last argument. Now users can pass arguments to gplink via the
11751 -Wl option, main() uses pic16glue() to glue up pic16 programs

11765 gpasm complaining and test the linkage with gplink, _linkCmd and
11766 _asmCmd changed to be more gplink and gpasm friendly
11767 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11768 produced an error when parsed, peep rule 12 is added to utilize
11769 movff, but it is commented out since the pCode does not support
11770 yet a command with 2 address arguments
11772 2003-05-18 <johan AT balder>
11774 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12797 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12798 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12799 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
12800 * src/pic/pcode.c: outcommented unused variable to remove warnings
12801 * src/pic/ralloc.c: outcommented unused variable to remove warnings
12803 2003-01-06 <karl AT turbobit.com>
12804 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
12807 2003-01-06 <johan AT balder>
12809 * src/SDCCicode.c: fixed array add
12811 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12812 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12813 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12815 2003-01-04 <johan AT balder>
12817 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12819 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12820 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12822 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12823 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12824 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12826 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12827 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12829 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12830 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12832 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12833 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12835 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12837 * in /sdcc/as/mcs51/ changed these files in order to create an
12838 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12839 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12840 following files to include the previous two files: aslink.dsp,
12841 Makefile.aslink, Makefile.bcc, and Makefile.in.
12843 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12844 .adb instead of .cdb
12846 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12848 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12849 value from option --iram-size.
12851 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12853 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12856 2002-09-18 <wiml AT hhhh.org>
12858 * SDCClrange.h: exposed setFromRange() and setToRange()
12859 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12860 packRegsForAccUse() (bug 542397)
12861 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12862 multiple times and emitting the fetch operations more than once
12863 added aopGetUsesAcc() function to allow binary operators to
12864 fetch their operands in the correct order; made genMinus() emit
12865 compact code for X = LITERAL - Y
12867 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12868 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12869 sprintf() in line 1267.
12871 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12872 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12875 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12876 Changes to aslink (All the changes are marked with 'JCF'):
12878 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12881 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12882 area BSEG. Also moves, if possible, the DATA area down into the internal
12883 ram so more space is available.
12885 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12888 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12889 not bytes. Function summary() which creates a memory usage summary
12890 file with extension .mem. Reports of overlaping stack and small stack
12891 size. If the space for the stack is less than 16 bytes aslink trows a
12894 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12895 the 8051. Option 'y' for memory summary output file.
12897 Changes to sdcc (All the changes are marked with 'JCF'):
12899 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12901 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12902 overlaying area for it (uses RegBankUsed[4]).
12904 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12905 bank zero as used by default. By default aslink locates the stack
12906 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12907 the creation of the .mem file. Delegates the allocation of data area
12908 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12909 the begining of the stack area to aslink.
12911 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12912 glue() in SDCCglue.c creates an area for it.
12914 2002-09-03 Borut Razem <borut.razem AT siol.net>
12915 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12916 sdcc/src/pic/glue.c:
12917 introduced atexit() handler for teporay files removal in case of
12918 errors, assertions, ...
12920 2002-08-29 Borut Razem <borut.razem AT siol.net>
12921 * sdcc/support/cpp2/auto-host_vc_in.h:
12922 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12923 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12924 Maybe there is a similar problem with BORLANDC? It should be checked!
12926 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12927 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12928 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12929 was not executed, and the compiler (cl) launched a warning:
12930 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12932 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12933 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12935 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12936 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12938 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12939 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12940 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12941 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12942 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12943 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12944 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12945 - added Release configuration in VS projects
12946 - review of compiler an linker options
12947 - VC .exe files are generated in bin_vc directory, not to interfere
12948 with binaries generated from other projects (cygwin, mingw, bcc ...)
12950 * sdcc/src/yacc.dsp: added
12952 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12953 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12954 and insert the version number definitions from .version
12956 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12958 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12959 added - genarate auto-host.h using auto-host_vc_in.h as template
12962 removed from CVS, generated automatically
12964 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12965 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12967 2002-08-11 Borut Razem <borut.razem AT siol.net>
12968 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12970 2002-08-10 Borut Razem <borut.razem AT siol.net>
12971 * src/SDCCmain.c (main):
12972 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12973 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12974 The consequence was that some temporary files were not removed.
12977 unification of code in functions tempfilename() and tempfile():
12978 function tempnam() is defined in Visual Studio 6.0 and .NET
12980 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12982 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12983 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12984 - removed compiler command line option /WX: Treats all warnings as errors
12985 - update a list of source files, included into the project
12987 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12988 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12989 changed project type to Generic Project so that can be correcly converted to VS.NET project
12991 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12993 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12995 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12997 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12998 added return 0 statements after assert() to make compiler happy
13000 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13001 added newline in the def file to keep MSC compiler satisfied
13003 * sdcc/src/z80/gen.c:
13004 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13005 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13006 - solved MSC error in function aopDump()
13008 * sdcc_vc.h: define PREFIX as "\\sdcc"
13010 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13011 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13014 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13015 - Rewrote the register banking algorithm.
13016 - Added pCode live-range analysis to registers (for now, only non-used and
13017 singly-used registers optimized away)
13019 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13021 * 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.

13044 * src/z80/main.c: Added force callee saves for jaune.
13046 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13048 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13050 2002-03-28 Johan Knol <johan AT balder>
13052 * src/SDCCval.c: fixed bug #532436
13054 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13056 Added "char *Processor" field to the port structure.
13059 Added -p option. Allows port dependent processor to be specified.
13062 Initialized the new field char *Processor field to NULL in all ports
13065 Compiler generated registers for interrupt context saving
13066 were not getting allocated.
13068 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13071 Fixed left shift. Will promote the left side of a left shift
13072 if a) left shifting more than size of operand or b) when assigned
13073 to something size > size of left side
13075 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13077 tons of changes. Register allocation has been
13078 rewritten. Added customization for the various PICs. Flow
13079 analysis is restructured. ...
13081 * src/pic/device.h:
13084 * src/pic/device.c:
13085 Added. device.c is a PIC port hack to accomodate variations
13088 2002-03-13 Michael Hope <michaelh AT vroom>
13090 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13092 2002-03-04 johanknol <johanknol AT manik>
13094 * /src/SDCCval.c: fixed
13096 const unsigned char arr[][2] = { { 0, 1 } };
13097 t18.c:1: error: Initializer element is not constant

13183 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13185 * sdcc/src/SDCCloop.c:
13186 Previous fix was not good. basic blocks that have "break" or "return" are
13187 not really partof a loop , but live ranges used in these blocks should
13188 be live thru the entire loop, so set partOfLoop but don't add them to
13191 2002-02-21 <johan AT FRIJA>
13193 * src/SDCCcse.c: fixed bug #514308
13195 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13198 Fixed BUG #519583. If a conditional block ended in a return/break
13199 statement inside a loop, it was not being considered part of the loop.
13201 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13203 2002-02-10 Karl Bongers <karl AT turbobit.com>

13207 with lots of comments and notes.
13209 * device/examples/test2.c:
13210 Fix bug, "red" variable not being initialized(compiler complained).
13212 * device/examples/Makefile, examples/test3.c:
13213 Add Makefile in device/examples folder, compiles test3.c
13214 for use as a multiple module SDCDB test case.
13216 * sim/ucsim/cmd.src/cmdset.cc:
13217 Took out debug printfs in ucsim "next" command.
13219 * sim/ucsim/xa.src:
13220 Karl and Johan start ucsim XA support. Most dissassembly working,
13221 about 75% emulation done(plenty of work remaining).
13223 * sim/ucsim/z80.src:
13224 Add Z80 support to ucsim, add test-ucz80 regression test,
13225 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13226 Notice z80 compiler fails on examples/test3.c/crc code.
13228 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13230 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

13238 from a memory mapped port
13239 2) added __builtin_memcmp
13240 3) added __builtin_swapw swap bytes of a short
13242 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13243 1) handle multiple send & receives from register bank1
13244 2) ralloc can now allocate DPTR1 to some liveRanges
13246 * src/SDCCsymt.c, src/SDCCsymt.h:
13247 changes to handle multiple sends & receives
13249 * src/SDCCptropt.h:
13250 added some pointer arithmetic optimization
13252 * src/SDCCptropt.c:
13253 added some pointer arithmetic optimizations but not stable yet so not
13254 called from anywhere (will get this working shortly)
13256 * src/SDCCopt.c: fixed for multiple sends & receives
13259 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
13260 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
13261 set preprocessor defines (depending on options)
13263 * src/SDCCicode.c, src/SDCCicode.h:
13264 changes made to handle multiple sends & receives
13267 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
