2955 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2957 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2958 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2960 One basic decision: e.g. src/clean.mk includes further files. In order
2961 to make this work there are two solutions:
2962 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2963 run configure on them. This way they can use
2964 'include $(srcdir)/port-clean.mk'
2965 - always include clean.mk by the Makefile at the same level. To avoid
2966 that `make clean` tries to include and build Makefile.dep the
2967 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2968 implemented, because now even `make uninstall` doesn't create
2969 Makefile.in. clean.mk could be eliminated by pasting it in
2972 * debugger/mcs51/Makefile.in: build own objects from library sources
2973 (SLIB, SDCC) in current directory
2975 * configure, configure.in: renamed --disable-device-lib-build in
2976 --disable-device-lib; added --enable-doc, the required tools are
2977 searched by configure; added result message; the toolchain for the
2978 belonging ports are now only built, if the port is enabled.
2980 * support/regression/*: all output is written in directory gen, because
2981 the fwk and ports directories don't livet in the build tree using vpath
2983 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2984 --disable-device-lib, added --enable-doc, added section VPATH
2986 * sim/ucsim/configure.in,
2987 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2988 z80 are enabled by default
2990 2006-04-24 Raphael Neider <rneider AT web.de>
2992 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2993 to config word, "pic14_"-prefixed some extern functions
2994 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2995 config word has been found
2996 * src/pic/device.h: added prototypes
2997 * src/pic/pcode.c: added "pic14_"-prefix where needed
2998 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3000 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3002 (pic14emitRegularMap): ignore config words,
3003 (pic14createInterruptVect): moved generating __config directives away
3004 (picglue): have __config directives emitted
3006 2006-04-24 Borut Razem <borut.razem AT siol.net>
3008 * doc/Makefile: sync with nightly build makefile
3010 2006-04-24 Raphael Neider <rneider AT web.de>
3012 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3013 registers that have not been assigned proper liveranges,
3014 fixes #1469504 and #1474602,
3015 (pCodeRegOptimizeRegUsage): fixed typo in comment
3017 2006-04-24 Borut Razem <borut.razem AT siol.net>
3019 * device/examples/main8051.c: deleted - it was removed from CVS
3020 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3021 after the transition to Subversion
3022 * src/SDCCalloc.h: deleted - it was removed from CVS
3023 3.feb.2001 and after that modified 18.feb.2001, so it reappered
3024 after the transition to Subversion

3262 interrupts need an interrupt number now if they are made critical),
3263 and enabled nesting of critical functions though not for gbz80
3264 (genCritical, genEndCritical): added functions
3265 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3266 * src/z80/mappings.i: added "ei" to all mappings

3278 the left operand is shorter than the result (c* = lit-c* + int),
3280 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3283 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3285 * src/.version: increased version number to 2.5.5
3286 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3287 linking is done manually in pic16 port's _linkEdit,
3288 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3289 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3290 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3291 allocate asmop as AOP_ACC,
3292 (aopForRemat): added parameter 'bool result' in function declaration,
3293 (pic16_aopGet): return AOP_ACC when accessing WREG,

3305 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3306 call to allocReg, not by manually allocating a new one,
3307 (pic16_assignRegisters): now before going through the register
3308 allocating functions mark all registers as free. This eliminates some
3309 side effects resulting from peephole parser done earlier in the backbone

3369 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3370 which dumps before the function entry point a data byte which represents
3371 the number of the local variables used by the specified function, added
3372 'xinst' for initial support for Extended Instruction Support,
3373 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3374 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3375 port->fun_prefix anymore (may change later),
3376 (genFunction, genEndFunction): do not store/restore local registers for
3377 _main (this should take care the --main-return command line option in
3379 (genOr): removed some legacy pic-port instructions,
3380 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3381 performing operations with SFR's causes data to be written more than
3382 once to each SFR. Perhaps SFRs should be handled in special cases...
3383 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3385 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3386 into account for stack starting position,

3390 (deassignLRs): *** perhaps the most important change, old 'for' code
3391 (commented out for reference), didn't account for some registers which
3392 were left marked 'not free' after a pointer operation. The change
3393 reduces register usage a lot in some cases
3395 2006-03-04 Borut Razem <borut.razem AT siol.net>

5669 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5670 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5671 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5672 always available in leading double underscore form. The C99 support is
5673 mostly missing, but it's a start.
5674 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5675 reserved identifier "__data".

5753 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5755 * device/lib/printf_large.c: removed inline assembly for portability and
5756 readability. Use printf_fast if speed or size are more important.
5757 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5758 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5760 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5762 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5763 prevent compiler warning
5765 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5767 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5768 moved to level 0 and declared as static. Also they are explicit
5769 placed in access bank. This was necessery because some times they
5770 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5771 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5772 optimizations. Currently only compare to unsigned char is implemented,
5773 * src/pic16/gen.c: added fReturnIdx array,
5774 * (struct resolvedIfx) is moved to gen.h and made public,
5775 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5776 * (aopForSym): added an optimization to directly store in stack of
5777 the operand of a SEND iCode,
5778 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5779 but as registers instead (AOP_REG) using the fReturnIdx array,
5780 * (pic16_freeAsmop): remove the freed register from the
5781 _G.sregsAlloc field,
5782 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5783 a compare of 'WREG',
5784 * (pic16_popGetTempRegCond): changed function prototype, now
5785 function takes also a bitVector argument v which holds the current
5786 set of registers that are allocated for stack access by aopForSym,
5787 registers allocated in aopForSym for accessing stack symbols are not
5788 any more part of the functions usedRegs field,
5789 * (genCall): some times aopOp is called for a stack variable to be
5790 send, aopForSym might perform the push, if this is true make sure
5791 that genCall doesn't push the variable twice by testing _G.resDirect,
5792 * (genFunction): changed testing for unspecified interrupt number
5793 from 256 to INTNO_UNSPEC,
5794 * modified selection scheme of frame pointer generation. Previously
5795 if function did use local registers a frame pointer was generated,
5796 now a frame pointer is generated only if function has arguments
5797 (that need PLUSW2 register access), or has stack arguments, or the
5798 compiler is not instructed to omit the frame pointer,
5799 * (genEndFunction): before restoring local registers that were saved
5800 in the function preamble, also restore the registers that *might*
5801 have been allocated for stack access,
5802 * (genRet): removed some old comments,
5803 * (genCmp, the active (RN's) version): added a call to the
5804 pic16_genCmp_special function to perform the compare with a more
5805 robust and optimized way,
5806 * (genInline): a feature has been added in inline code generation,
5807 which allows a wildcard variable substitution when writing inline
5808 assembly. Code is incomplete and experimental therefore undocumented,
5809 * (genCast): changed order of aopOp for result and right to allow
5810 aopForSym to directly load the result if possible,
5811 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5812 perform an optimized compare on some selected special occasions,
5813 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5814 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5815 generate an IVT any more,
5816 * src/pic16/main.c (pic16_optionsTable): added command line option
5818 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5819 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5821 * src/pic16/NOTES: Raphael Neider added in list of active developers
5822 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5823 jumptable_end to prevent bug #,
5824 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5825 inCond and outCond fields,
5826 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5827 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5828 turn off register spilling,
5829 * (packRegsForOneUse): synced with other ports' versions although it
5830 is not used currently,
5831 * (pic16_packRegisters): added an optimization while reading
5832 structure bitfields, some registers may be saved (malloc code is
5833 decreased by 80 bytes)
5835 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5837 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5838 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5839 this can be optimized more?
5841 2005-03-10 Raphael Neider <rneider AT web.de>
5843 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5844 genNearPointerGet): (hopefully) fixed access to bitfields via
5845 pointers (p->bitN = x; and x = p->bitN; failed)
5847 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6479 Adding support for replacing ljmps with sjmps in jumptables
6480 generated for switch statements. For now you need to set the
6481 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6482 Now 4 algorithms for mcs51 jumptable generation are used:
6483 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6484 addresses loaded pc-relative for up to 112 cases and stack-pushing
6485 target addresses loaded with offset from dptr for up to 256 cases.

6512 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6513 to call when a stack overflow occurs,
6514 * (malloc.h): added CVS Id tag,
6515 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6517 * added libc directory. The current version of LibC contains string
6518 functions, ctype functions and macros and some functions of the
6519 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6520 be extensively tested in the future. Standard disclaimer here.
6521 Library is not automatically build yet. But one can build it by
6522 invoking 'make' inside the libc directory.
6523 * added ADC library under libio. Preliminary version yet.
6525 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6532 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6533 * (pic16_storeForReturn): optimized return of 0,
6534 * (genCmp): experimental code for new genCmp which uses PIC18's
6535 special compare&skip instructions. Initial tests fail some times
6536 with variables grater than 1 byte in size, so new code is disabled,
6537 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6539 * (genCast): began a fix to optimize the casting of a bit to another
6540 bit, now assigning a bitfield to another bitfield will fail, sorry,
6541 * src/pic16/main.c: disabled the use of lr-support feature,
6542 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6543 * added some function prototypes, added function _debugf prototype,

6545 bits with offset (case PO_GPR_BIT),
6546 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6548 * (isBankInstruction): modified to return 0 for no banking instruction,
6549 and 1 for banking instruction,
6550 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6551 caused stop processing pCodes after a inline assembly block,
6552 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6553 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6554 registers when it shouldn't,
6555 * src/pic16/ralloc.c (allocReg): add preliminary support for
6556 supporting a limited set of temporary registers,
6558 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6560 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6561 genDataPointerSet): ensure assignments always copy in MSB to LSB
6563 (loadRegFromAop): recognize CLRH optimization,
6564 (genFunction): optimize RECEIVE iCodes in reentrant functions
6566 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6568 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9563 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9565 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9566 loaded with the linker search paths (-L arguments) and the libraries
9567 to be linked with the current source (-l arguments). Changes
9568 currently will affect only the pic16 port.
9569 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9570 include path the port specific paths and port specific libraries,
9571 * gplink command now contains the $3 argument,
9572 * src/pic16/device.h,
9573 * src/pic16/device.c,: structure PIC_device is made public and
9574 renamed to PIC16_device, the same for variable Pics which is renamed
9575 to Pics16. Updated all references to them.

9587 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9589 Documenting changes from previous commits.
9590 * configure.in (version 1.56),
9591 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9592 when generating output files to configure the pic16 library,
9593 but now I've commented it out, since gputils aren't installed in the
9594 SF compile farm, so library won't compile
9596 * device/lib/Makefile.in (version 1.56): initially I've added in
9597 target 'all' the prerequestive 'model-pic16' so it compiled the
9598 pic16 library, but now I've commented it out for the same reasons
9600 * added targets 'model-pic16' and 'objects-pic16' to compile the
9602 * added target 'port-specific-objects-pic16' to handle the
9603 generated libraries and copy them into the build/ directory
9604 * added target 'clean-intermediate-pic16' to clean intermediate
9605 files into pic16 directory
9606 * in target 'installdirs' added line to create directory pic16 in
9607 the installation path
9609 * device/include/Makefile.in (version 1.11): in target 'install'
9610 added lines to copy all header files to installation path,
9611 * in target 'installdirs' added line create directory for pic16
9612 headers in the installation path

9627 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9628 option so that it actually works. Made it specific to the z80, since
9629 the gbz80 doesn't have these kinds of I/O ports.
9631 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9633 * device/include/z180.h,

9646 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9648 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9649 changed interrupt vector table generation to only emit declared vectors.
9650 * device/include/Makefile.in: added missing backslash
9651 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

9655 Mainly changes to support compilation of the device libraries
9656 * src/pic16/device.c: stack is allocated via symbol and not
9657 via literal number. The symbol is placed in the corresponding
9658 position of the data ram
9659 * (pic16_dump_section): relocatable and absolute uninitialized
9660 data are now emitted in sorted order to reduce section naming,
9661 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9662 weren't marked as being in the access bank,
9664 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9666 Added portion of GNU PIC Library under the directory
9667 device/include/pic16 and device/lib/pic16. These files
9668 contain the declarations of SFRs for the PIC18Fxx2 devices.
9669 The directory is initialized via configure from toplevel.
9671 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9673 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9674 the spilllocations to be compared correctly
9676 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9678 * src/SDCCast.c (decorateType): fixed bug introduced today
9680 2004-01-12 Borut Razem <borut.razem AT siol.net>
9682 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

9698 * doc/sdccman.lyx: Moved and added some sections, small changes
9699 all over. Telling LaTeX to be less strict with word spacing
9700 to better keep the right margin. Changed some notes about
9701 maintainance of the ports in section 3.2.1 - is it OK like this?
9703 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9740 UPPER for immediate operands,
9741 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9743 * src/pic16/peeph.def: all peepholes with movff are commented out,
9744 because there is a problem in the pcode peep optimizer,
9745 * src/pic16/ralloc.c: the register allocator can now reuse local

9747 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9749 Added file src/pic16/NOTES with information about program writing on
9750 the current port version.

9782 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9785 * src/z80/main.c: added missed needLinkerScript flags (more than
9786 one port structure defined in these file)
9787 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9803 needLinkerScript flag
9805 * src/pic16/gen.c (genAddrOf): fixed bug #863624
9806 * src/pic/glue.c: added variable udata_section_name to
9807 override default uninitialized data segment definition for

9810 directive when no overlay data exist
9811 * (picglue): modified to emit uninitialized data segment
9812 according to udata_section_name

9838 include information about variables allocated to the overlay
9841 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9843 * as/mcs51/lkmain.c: Help about -Y option

9855 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9857 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9858 (default behaviour).
9860 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9862 A python script to validate compiler diagnostic messages. It can be
9863 used to verify that sdcc complains about bad c source code and
9864 gives a good location of the error.
9865 * support/valdiag/Makefile,
9866 * support/valdiag/valdiag.py,
9867 * support/valdiag/tests/*

9884 Bug reported from Jesus Calvino-Fraga
9886 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9888 * sdcc.spec: updated
9889 * device/include/Makefile.in: don't install CVS directories
9890 * device/lib/Makefile.in: added removal of CVS directories after install
9891 * doc/Makefile: fixed install, added local_icons
9892 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9893 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9894 * src/ds390/gen.c (genRightShift): fixed bug #870788
9895 * src/SDCCast.c (decorateType): fixed bug #870781
9897 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9899 PIC16 port related changes:
9900 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9901 added variable stackPos,
9903 * gen.c: genCall, assignResultValue: added support for
9904 pushing/retrieving function parameters to/from stack,
9905 genFunction,genEndFunction: setup stack frame for the
9907 genAddrOf: will be changed according to bug 863624
9909 * added files genutils.c and genutils.h which contain gen*
9910 debugged and optimised functions extracted from gen.c
9912 * glue.c: added variable 'externs' which holds extern symbols,
9913 pic16emitRegularMap: is modified to properly handle relocatable
9914 symbols under the new scheme,
9915 pic16createInterruptVect: is modified
9916 pic16printPublics: is modified to emit 'global' assembler directives,
9917 added pic16_printExterns to print extern symbols,
9918 pic16glue: initializes stack/frame pointer in the beginning of
9919 the assembly output. Temporary hack, will be corrected later,
9920 because gplink yet does not support stack and SDCC does not
9921 yet support a type of crt0.o object to create the final binary.
9923 * Removed many lines that contain 8051 legacy code.
9924 * The code is finally placed under a 'code' directive.
9925 * Added port specific options.
9927 * _process_pragma: simplified since now we do not need *special*
9928 include file to define SFR registers. But a separate header
9929 will be needed. This will be developed later.
9930 * _pic16_parseOptions: added, parses port specific options:
9931 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9932 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9933 --preplace-udata-with=
9935 * _pic16_setDefaultOptions: modified to initialize section names,
9936 but hack is temporarly out of order since it needs improvement.
9937 * _pic16_genAssemblerPreamble: configuration words are emitted by
9938 their address instead of their name. This part is incomplete and
9939 supports only the 18Fxx2 devices. Other devices will emit an error
9940 during assembly since they do not contain the same set of config
9942 * _pic16_genIVT: is modified,
9944 * pcode.c: added definitions for some hardware registers that are needed
9946 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9947 All PCI entries are updated. Now LFSR is supported.
9948 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9949 * added pic16_newpCodeOpLit2 to support instructions with
9950 two literal arguments
9951 * pic16_pCode2str: corrected code that emits assembler instructions
9952 with two literal operands and those that have an access bit modifier
9953 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9954 this fixes a bug which caused some labels to be lost, when an
9955 assembler directive was added, i.e. banksel,
9956 * pic16_FixRegisterBanking: improved logic that causes the insertion
9958 * InlineFunction: functions that are called once, are not any more
9959 inlined. This can be a port option in the future,
9961 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9963 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9964 hold the corresponding uninitialized symbols,
9965 * pic16_allocProcessorRegister: registers have explicit marked the
9967 * pic16_allocInternalRegister: registers are explicit marked as
9969 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9970 processing list, so bit registers were lost,
9973 * ralloc.h: added field 'accessBank' and original symbol operand
9974 in register definition,
9975 * removed the field isMapped from register definition,
9977 ** Several functions have been removed from various sources:
9978 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9979 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9980 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9981 pic16_assignRelocatableRegisters
9983 ** others have been introduced:
9984 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9985 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9987 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9989 * support/scripts/inc2h.pl: changed definition of BIT_AT
9990 to emit 'sbit at' instead of 'bit at'. This was a request.
9992 PIC16 port related preliminary changes:
9993 * gen.c: prefixed function popRegFromString with
9994 pic16_ and all references to it corrected
9995 * pcode.c: all pic16_pc_* hardware registers prefixed
9996 with underscore (_),
9997 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9998 * ralloc.c: newReg(): when register is REG_SFR then
9999 set address to rIdx,
10000 pic16_allocProcessorRegister(): marks register wasUsed=0
10001 pic16_writeUsedRegs(): added a call to assign processor
10002 registers via pic16_assignFixedRegisters
10004 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10006 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10007 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10008 variables in unused register banks. Also the SSEG is placed
10009 wherever there is enough space for it, and IDATA can be anywhere
10010 in internal RAM. For now compile using -Wl-Y[stack_size].
10011 The mem file is different for this option as well, since it
10012 makes no sense of talking about DSEG lenght.

11007 and JUMPTABLE iCodes properly now (worked by accident before)
11008 * src/mcs51/gen.c (leftRightUseAcc),
11009 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11010 iCode properly now. Use getSize instead of nRegs since a & b

11025 copied from genNearPointerSet()
11026 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11027 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11028 If they pop r0/r1 they must be called in the opposite order than aopOp().
11029 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11030 (resp. --stack-auto), prepared for --xstack
11032 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11041 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11043 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11044 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11045 type for bits was changed. It resulted in bit variables becoming
11046 global, which is not permitted in PIC 14 assembly output.
11048 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11050 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11052 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11054 Z80 and MCS51 linkers complaint if a public symbol is defined
11055 in more than one library module:
11059 * as/mcs51/Makefile.in
11061 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11063 A few small changes that speed up the peephole optimizer.
11067 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11069 Try to make the peephole optimizer smarter by maintaining
11070 an association between the assembly source code and the
11071 iCodes that originated them. Put this information to use
11072 with a new peephole rule condition "notVolatile" so that
11073 the rules can be aggressive yet still safe.
11078 * src/mcs51/peeph.def
11080 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11084 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11085 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11086 if the left or right operand symbols have the accuse flag set.
11088 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11090 Changed the type of the result of the ! (NOT) operator to char;
11091 previously it returned the same type as the source. This allows
11092 us to eliminate all the genFloatNot functions (all of its target
11093 implementations were very buggy) since !float can use the same
11096 * src/SDCCicode.c (ast2iCode): ! returns char
11097 * src/mcs51/gen.c (genNot, genNotFloat),
11098 * src/ds390/gen.c (genNot, genNotFloat),
11099 * src/z80/gen.c (genNot, genNotFloat),
11100 * src/pic/gen.c (genNot, genNotFloat),
11101 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11105 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11106 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11107 during interrupts. Ensure WSAVE is located at a shared bank address.
11108 2. Fixed page selection in some places
11109 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11110 the registers name strings.
11111 4. Fixed "signed / unsigned compare" compiler warnings.
11112 5. The PIC port manages its own allocation of the general purpose
11113 registers, but makes no attempt to reuse them. As a result when
11114 compiling it soon runs out of general purpose registers. Some
11115 additional code was added to the files pcode.c and device.c to walk
11116 through the function call tree and rename the registers so that they
11126 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11127 genPlus() & genMinus() when the result is the same as left or right
11129 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11133 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11135 Made bitfield a distinct type from bit so that bitfields
11136 convert as per ANSI C and bits retain their traditional
11137 boolean style behaviour. Implemented bitfield support in
11145 * src/ds390/gen.c: bit v bitfield split
11146 * src/z80/gen.c: New support for bitfields
11147 * support/regression/tests/bitfields.c: reenabled z80,
11150 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11152 Rules 246.x, 247.x relate to bitfields, the others speed up
11153 access to xdata mapped I/O devices.
11155 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11157 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11159 Cleaned up genPackBits and genUnpackBits and added two helper
11160 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11161 for literal assignments in genPackBits (thanks to Frieder for
11167 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11169 Fixed bug #748310 (pointer to function type mishandled when the
11170 function name is omitted). Also fixed a SIGSEGV when a function
11171 attribute (reentrant, etc) is used on a non-function or on a
11172 function but misplaced before the parameter list.
11174 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11176 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11177 * support/Util/SDCCerr.h,
11178 * support/Util/SDCCerr.c: Added func attr misuse error msg
11180 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11182 Fixed bug #787649 by anonymous
11183 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11184 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11186 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11199 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11201 Made the constant following the "interrupt" keyword optional. If
11202 omitted, the function will not automatically be given an entry
11203 in the interrupt vector table (similar to #pragma NOIV, but
11204 less syntacticly kludgy). The interrupt number is also now
11205 range checked. Also fixed a bug in the high order bit example
11212 * support/Util/SDCCerr.c
11213 * support/Util/SDCCerr.h
11216 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11221 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11223 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11224 be re-activated by defining REDUCE_LITERALS)
11225 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11226 unsigned, but are signed by default
11227 * src/SDCCval.c (constVal): rearranged
11228 * src/SDCCval.c (valMod): preliminary fix
11229 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11269 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11270 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11271 constants are unsigned; added recognition of "u" flag for unsigned
11272 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11273 * src/SDCCval.c (valDiv, valMod): fixed signdness

11735 added if/endif conditional macros to remove options help
11736 messages from optionsTable when a port is not configured, added
11737 support for the PIc16 port in the ports table, when executing
11738 the compiler with no port specified on command line, a default
11739 port is selected with the new macro DEFAULT_PORT which is
11740 defined in port.h, in setDefaultOptions() linkOptions is removed
11741 from initialization assignment, since now it is a set,
11742 parseCmdLine uses setParseWithComma for linkOptions, in
11743 linkEdit() linkOptions are accessed with new function indexSet()
11744 which returns the i'th item of a set variable. See SDCCset.c, in
11745 linkEdit() when calling buildCmdLine(), added linkOptions as
11746 last argument. Now users can pass arguments to gplink via the
11747 -Wl option, main() uses pic16glue() to glue up pic16 programs

11761 gpasm complaining and test the linkage with gplink, _linkCmd and
11762 _asmCmd changed to be more gplink and gpasm friendly
11763 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11764 produced an error when parsed, peep rule 12 is added to utilize
11765 movff, but it is commented out since the pCode does not support
11766 yet a command with 2 address arguments
11768 2003-05-18 <johan AT balder>
11770 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12793 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12794 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12795 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
12796 * src/pic/pcode.c: outcommented unused variable to remove warnings
12797 * src/pic/ralloc.c: outcommented unused variable to remove warnings
12799 2003-01-06 <karl AT turbobit.com>
12800 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
12803 2003-01-06 <johan AT balder>
12805 * src/SDCCicode.c: fixed array add
12807 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12808 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12809 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12811 2003-01-04 <johan AT balder>
12813 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12815 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12816 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12818 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12819 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12820 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12822 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12823 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12825 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12826 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12828 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12829 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12831 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12833 * in /sdcc/as/mcs51/ changed these files in order to create an
12834 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12835 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12836 following files to include the previous two files: aslink.dsp,
12837 Makefile.aslink, Makefile.bcc, and Makefile.in.
12839 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12840 .adb instead of .cdb
12842 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12844 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12845 value from option --iram-size.
12847 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12849 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12852 2002-09-18 <wiml AT hhhh.org>
12854 * SDCClrange.h: exposed setFromRange() and setToRange()
12855 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12856 packRegsForAccUse() (bug 542397)
12857 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12858 multiple times and emitting the fetch operations more than once
12859 added aopGetUsesAcc() function to allow binary operators to
12860 fetch their operands in the correct order; made genMinus() emit
12861 compact code for X = LITERAL - Y
12863 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12864 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12865 sprintf() in line 1267.
12867 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12868 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12871 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12872 Changes to aslink (All the changes are marked with 'JCF'):
12874 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12877 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12878 area BSEG. Also moves, if possible, the DATA area down into the internal
12879 ram so more space is available.
12881 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12884 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12885 not bytes. Function summary() which creates a memory usage summary
12886 file with extension .mem. Reports of overlaping stack and small stack
12887 size. If the space for the stack is less than 16 bytes aslink trows a
12890 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12891 the 8051. Option 'y' for memory summary output file.
12893 Changes to sdcc (All the changes are marked with 'JCF'):
12895 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12897 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12898 overlaying area for it (uses RegBankUsed[4]).
12900 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12901 bank zero as used by default. By default aslink locates the stack
12902 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12903 the creation of the .mem file. Delegates the allocation of data area
12904 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12905 the begining of the stack area to aslink.
12907 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12908 glue() in SDCCglue.c creates an area for it.
12910 2002-09-03 Borut Razem <borut.razem AT siol.net>
12911 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12912 sdcc/src/pic/glue.c:
12913 introduced atexit() handler for teporay files removal in case of
12914 errors, assertions, ...
12916 2002-08-29 Borut Razem <borut.razem AT siol.net>
12917 * sdcc/support/cpp2/auto-host_vc_in.h:
12918 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12919 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12920 Maybe there is a similar problem with BORLANDC? It should be checked!
12922 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12923 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12924 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12925 was not executed, and the compiler (cl) launched a warning:
12926 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12928 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12929 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12931 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12932 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12934 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12935 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12936 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12937 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12938 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12939 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12940 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12941 - added Release configuration in VS projects
12942 - review of compiler an linker options
12943 - VC .exe files are generated in bin_vc directory, not to interfere
12944 with binaries generated from other projects (cygwin, mingw, bcc ...)
12946 * sdcc/src/yacc.dsp: added
12948 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12949 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12950 and insert the version number definitions from .version
12952 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12954 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12955 added - genarate auto-host.h using auto-host_vc_in.h as template
12958 removed from CVS, generated automatically
12960 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12961 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12963 2002-08-11 Borut Razem <borut.razem AT siol.net>
12964 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12966 2002-08-10 Borut Razem <borut.razem AT siol.net>
12967 * src/SDCCmain.c (main):
12968 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12969 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12970 The consequence was that some temporary files were not removed.
12973 unification of code in functions tempfilename() and tempfile():
12974 function tempnam() is defined in Visual Studio 6.0 and .NET
12976 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12978 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12979 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12980 - removed compiler command line option /WX: Treats all warnings as errors
12981 - update a list of source files, included into the project
12983 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12984 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12985 changed project type to Generic Project so that can be correcly converted to VS.NET project
12987 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12989 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12991 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12993 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12994 added return 0 statements after assert() to make compiler happy
12996 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12997 added newline in the def file to keep MSC compiler satisfied
12999 * sdcc/src/z80/gen.c:
13000 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13001 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13002 - solved MSC error in function aopDump()
13004 * sdcc_vc.h: define PREFIX as "\\sdcc"
13006 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13007 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13009 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13010 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13011 - Rewrote the register banking algorithm.
13012 - Added pCode live-range analysis to registers (for now, only non-used and
13013 singly-used registers optimized away)
13015 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13017 * 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.

13040 * src/z80/main.c: Added force callee saves for jaune.
13042 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13044 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13046 2002-03-28 Johan Knol <johan AT balder>
13048 * src/SDCCval.c: fixed bug #532436
13050 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13052 Added "char *Processor" field to the port structure.
13055 Added -p option. Allows port dependent processor to be specified.
13058 Initialized the new field char *Processor field to NULL in all ports
13061 Compiler generated registers for interrupt context saving
13062 were not getting allocated.
13064 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13067 Fixed left shift. Will promote the left side of a left shift
13068 if a) left shifting more than size of operand or b) when assigned
13069 to something size > size of left side
13071 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13073 tons of changes. Register allocation has been
13074 rewritten. Added customization for the various PICs. Flow
13075 analysis is restructured. ...
13077 * src/pic/device.h:
13080 * src/pic/device.c:
13081 Added. device.c is a PIC port hack to accomodate variations
13084 2002-03-13 Michael Hope <michaelh AT vroom>
13086 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13088 2002-03-04 johanknol <johanknol AT manik>
13090 * /src/SDCCval.c: fixed
13092 const unsigned char arr[][2] = { { 0, 1 } };
13093 t18.c:1: error: Initializer element is not constant

13179 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13181 * sdcc/src/SDCCloop.c:
13182 Previous fix was not good. basic blocks that have "break" or "return" are
13183 not really partof a loop , but live ranges used in these blocks should
13184 be live thru the entire loop, so set partOfLoop but don't add them to
13187 2002-02-21 <johan AT FRIJA>
13189 * src/SDCCcse.c: fixed bug #514308
13191 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13194 Fixed BUG #519583. If a conditional block ended in a return/break
13195 statement inside a loop, it was not being considered part of the loop.
13197 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13199 2002-02-10 Karl Bongers <karl AT turbobit.com>

13203 with lots of comments and notes.
13205 * device/examples/test2.c:
13206 Fix bug, "red" variable not being initialized(compiler complained).
13208 * device/examples/Makefile, examples/test3.c:
13209 Add Makefile in device/examples folder, compiles test3.c
13210 for use as a multiple module SDCDB test case.
13212 * sim/ucsim/cmd.src/cmdset.cc:
13213 Took out debug printfs in ucsim "next" command.
13215 * sim/ucsim/xa.src:
13216 Karl and Johan start ucsim XA support. Most dissassembly working,
13217 about 75% emulation done(plenty of work remaining).
13219 * sim/ucsim/z80.src:
13220 Add Z80 support to ucsim, add test-ucz80 regression test,
13221 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13222 Notice z80 compiler fails on examples/test3.c/crc code.
13224 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13226 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

13234 from a memory mapped port
13235 2) added __builtin_memcmp
13236 3) added __builtin_swapw swap bytes of a short
13238 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13239 1) handle multiple send & receives from register bank1
13240 2) ralloc can now allocate DPTR1 to some liveRanges
13242 * src/SDCCsymt.c, src/SDCCsymt.h:
13243 changes to handle multiple sends & receives
13245 * src/SDCCptropt.h:
13246 added some pointer arithmetic optimization
13248 * src/SDCCptropt.c:
13249 added some pointer arithmetic optimizations but not stable yet so not
13250 called from anywhere (will get this working shortly)
13252 * src/SDCCopt.c: fixed for multiple sends & receives
13255 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
13256 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
13257 set preprocessor defines (depending on options)
13259 * src/SDCCicode.c, src/SDCCicode.h:
13260 changes made to handle multiple sends & receives
13263 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
