2970 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2972 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2973 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2975 One basic decision: e.g. src/clean.mk includes further files. In order
2976 to make this work there are two solutions:
2977 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2978 run configure on them. This way they can use
2979 'include $(srcdir)/port-clean.mk'
2980 - always include clean.mk by the Makefile at the same level. To avoid
2981 that `make clean` tries to include and build Makefile.dep the
2982 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2983 implemented, because now even `make uninstall` doesn't create
2984 Makefile.in. clean.mk could be eliminated by pasting it in
2987 * debugger/mcs51/Makefile.in: build own objects from library sources
2988 (SLIB, SDCC) in current directory
2990 * configure, configure.in: renamed --disable-device-lib-build in
2991 --disable-device-lib; added --enable-doc, the required tools are
2992 searched by configure; added result message; the toolchain for the
2993 belonging ports are now only built, if the port is enabled.
2995 * support/regression/*: all output is written in directory gen, because
2996 the fwk and ports directories don't livet in the build tree using vpath
2998 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2999 --disable-device-lib, added --enable-doc, added section VPATH
3001 * sim/ucsim/configure.in,
3002 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3003 z80 are enabled by default
3005 2006-04-24 Raphael Neider <rneider AT web.de>
3007 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3008 to config word, "pic14_"-prefixed some extern functions
3009 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3010 config word has been found
3011 * src/pic/device.h: added prototypes
3012 * src/pic/pcode.c: added "pic14_"-prefix where needed
3013 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3015 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
3017 (pic14emitRegularMap): ignore config words,
3018 (pic14createInterruptVect): moved generating __config directives away
3019 (picglue): have __config directives emitted
3021 2006-04-24 Borut Razem <borut.razem AT siol.net>
3023 * doc/Makefile: sync with nightly build makefile
3025 2006-04-24 Raphael Neider <rneider AT web.de>
3027 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
3028 registers that have not been assigned proper liveranges,
3029 fixes #1469504 and #1474602,
3030 (pCodeRegOptimizeRegUsage): fixed typo in comment
3032 2006-04-24 Borut Razem <borut.razem AT siol.net>
3034 * device/examples/main8051.c: deleted - it was removed from CVS
3035 24.mar.2000 and after that modified 18.feb.2001, so it reappered
3036 after the transition to Subversion

3253 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3255 * src/mcs51/gen.c (genCall): fixed bug 1457608
3257 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3276 implemented patch 1120823 Thanks to Willy De la Court (normal
3277 interrupts need an interrupt number now if they are made critical),
3278 and enabled nesting of critical functions though not for gbz80
3279 (genCritical, genEndCritical): added functions
3280 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3281 * src/z80/mappings.i: added "ei" to all mappings

3293 the left operand is shorter than the result (c* = lit-c* + int),
3295 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3298 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3300 * src/.version: increased version number to 2.5.5
3301 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3302 linking is done manually in pic16 port's _linkEdit,
3303 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3304 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3305 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3306 allocate asmop as AOP_ACC,
3307 (aopForRemat): added parameter 'bool result' in function declaration,
3308 (pic16_aopGet): return AOP_ACC when accessing WREG,
3309 (pic16_popGetTempReg): minor modification,

3320 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3321 call to allocReg, not by manually allocating a new one,
3322 (pic16_assignRegisters): now before going through the register
3323 allocating functions mark all registers as free. This eliminates some
3324 side effects resulting from peephole parser done earlier in the backbone
3326 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3384 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3385 which dumps before the function entry point a data byte which represents
3386 the number of the local variables used by the specified function, added
3387 'xinst' for initial support for Extended Instruction Support,
3388 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3389 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3390 port->fun_prefix anymore (may change later),
3391 (genFunction, genEndFunction): do not store/restore local registers for
3392 _main (this should take care the --main-return command line option in
3394 (genOr): removed some legacy pic-port instructions,
3395 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3396 performing operations with SFR's causes data to be written more than
3397 once to each SFR. Perhaps SFRs should be handled in special cases...
3398 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3400 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3401 into account for stack starting position,

3403 --extended or -y for Extended Instruction Support,
3404 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3405 (deassignLRs): *** perhaps the most important change, old 'for' code
3406 (commented out for reference), didn't account for some registers which
3407 were left marked 'not free' after a pointer operation. The change
3408 reduces register usage a lot in some cases
3410 2006-03-04 Borut Razem <borut.razem AT siol.net>

5677 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5679 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

5681 * src/SDCCglobal.h (struct options),
5683 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5684 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5685 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5686 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5687 always available in leading double underscore form. The C99 support is
5688 mostly missing, but it's a start.
5689 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5690 reserved identifier "__data".
5692 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5768 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5770 * device/lib/printf_large.c: removed inline assembly for portability and
5771 readability. Use printf_fast if speed or size are more important.
5772 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5773 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5775 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5777 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5778 prevent compiler warning
5780 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5782 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5783 moved to level 0 and declared as static. Also they are explicit
5784 placed in access bank. This was necessery because some times they
5785 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5786 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5787 optimizations. Currently only compare to unsigned char is implemented,
5788 * src/pic16/gen.c: added fReturnIdx array,
5789 * (struct resolvedIfx) is moved to gen.h and made public,
5790 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5791 * (aopForSym): added an optimization to directly store in stack of
5792 the operand of a SEND iCode,
5793 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5794 but as registers instead (AOP_REG) using the fReturnIdx array,
5795 * (pic16_freeAsmop): remove the freed register from the
5796 _G.sregsAlloc field,
5797 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5798 a compare of 'WREG',
5799 * (pic16_popGetTempRegCond): changed function prototype, now
5800 function takes also a bitVector argument v which holds the current
5801 set of registers that are allocated for stack access by aopForSym,
5802 registers allocated in aopForSym for accessing stack symbols are not
5803 any more part of the functions usedRegs field,
5804 * (genCall): some times aopOp is called for a stack variable to be
5805 send, aopForSym might perform the push, if this is true make sure
5806 that genCall doesn't push the variable twice by testing _G.resDirect,
5807 * (genFunction): changed testing for unspecified interrupt number
5808 from 256 to INTNO_UNSPEC,
5809 * modified selection scheme of frame pointer generation. Previously
5810 if function did use local registers a frame pointer was generated,
5811 now a frame pointer is generated only if function has arguments
5812 (that need PLUSW2 register access), or has stack arguments, or the
5813 compiler is not instructed to omit the frame pointer,
5814 * (genEndFunction): before restoring local registers that were saved
5815 in the function preamble, also restore the registers that *might*
5816 have been allocated for stack access,
5817 * (genRet): removed some old comments,
5818 * (genCmp, the active (RN's) version): added a call to the
5819 pic16_genCmp_special function to perform the compare with a more
5820 robust and optimized way,
5821 * (genInline): a feature has been added in inline code generation,
5822 which allows a wildcard variable substitution when writing inline
5823 assembly. Code is incomplete and experimental therefore undocumented,
5824 * (genCast): changed order of aopOp for result and right to allow
5825 aopForSym to directly load the result if possible,
5826 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5827 perform an optimized compare on some selected special occasions,
5828 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5829 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5830 generate an IVT any more,
5831 * src/pic16/main.c (pic16_optionsTable): added command line option
5833 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5834 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5836 * src/pic16/NOTES: Raphael Neider added in list of active developers
5837 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5838 jumptable_end to prevent bug #,
5839 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5840 inCond and outCond fields,
5841 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5842 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5843 turn off register spilling,
5844 * (packRegsForOneUse): synced with other ports' versions although it
5845 is not used currently,
5846 * (pic16_packRegisters): added an optimization while reading
5847 structure bitfields, some registers may be saved (malloc code is
5848 decreased by 80 bytes)
5850 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5852 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5853 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5854 this can be optimized more?
5856 2005-03-10 Raphael Neider <rneider AT web.de>
5858 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5859 genNearPointerGet): (hopefully) fixed access to bitfields via
5860 pointers (p->bitN = x; and x = p->bitN; failed)
5862 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5906 to keep the correct label reference count when adding/removing references
5907 to labels. A peephole file using this is appended to patch #1144962.

6494 Adding support for replacing ljmps with sjmps in jumptables
6495 generated for switch statements. For now you need to set the
6496 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6497 Now 4 algorithms for mcs51 jumptable generation are used:
6498 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6499 addresses loaded pc-relative for up to 112 cases and stack-pushing
6500 target addresses loaded with offset from dptr for up to 256 cases.

6527 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6528 to call when a stack overflow occurs,
6529 * (malloc.h): added CVS Id tag,
6530 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6532 * added libc directory. The current version of LibC contains string
6533 functions, ctype functions and macros and some functions of the
6534 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6535 be extensively tested in the future. Standard disclaimer here.
6536 Library is not automatically build yet. But one can build it by
6537 invoking 'make' inside the libc directory.
6538 * added ADC library under libio. Preliminary version yet.

6547 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6548 * (pic16_storeForReturn): optimized return of 0,
6549 * (genCmp): experimental code for new genCmp which uses PIC18's
6550 special compare&skip instructions. Initial tests fail some times
6551 with variables grater than 1 byte in size, so new code is disabled,
6552 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6554 * (genCast): began a fix to optimize the casting of a bit to another
6555 bit, now assigning a bitfield to another bitfield will fail, sorry,
6556 * src/pic16/main.c: disabled the use of lr-support feature,
6557 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6560 bits with offset (case PO_GPR_BIT),
6561 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6563 * (isBankInstruction): modified to return 0 for no banking instruction,
6564 and 1 for banking instruction,
6565 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6566 caused stop processing pCodes after a inline assembly block,
6567 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6568 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6569 registers when it shouldn't,
6570 * src/pic16/ralloc.c (allocReg): add preliminary support for
6571 supporting a limited set of temporary registers,
6573 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6575 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6576 genDataPointerSet): ensure assignments always copy in MSB to LSB
6578 (loadRegFromAop): recognize CLRH optimization,
6579 (genFunction): optimize RECEIVE iCodes in reentrant functions
6581 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6583 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9530 * src/pic/ralloc.h: applied patch from Slade Rich;
9531 added support for multiple code pages and multiple RAM banks on the
9532 PIC 14 port. The ASM files now no longer simply assume all the
9533 code / RAM are in the same page / bank. This means the linker can
9534 safely allocate code/RAM of separate ASM files to different pages/banks.
9535 * doc/sdccman.lyx: added Slade's tips
9536 * src/mcs51/peeph.def: fixed bug #880768

9545 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
9548 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9549 strtof is not part of C89 and isn't included with Mac OS X.
9551 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9553 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
9554 shiftL2Left2Result): fixed bug #879326
9555 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

9578 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9580 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9581 loaded with the linker search paths (-L arguments) and the libraries
9582 to be linked with the current source (-l arguments). Changes
9583 currently will affect only the pic16 port.
9584 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9585 include path the port specific paths and port specific libraries,
9586 * gplink command now contains the $3 argument,
9587 * src/pic16/device.h,
9588 * src/pic16/device.c,: structure PIC_device is made public and
9589 renamed to PIC16_device, the same for variable Pics which is renamed
9590 to Pics16. Updated all references to them.
9591 * src/pic16/glue.c (pic16glue): corrected bug with code
9592 initialization which bypassed the variable initializations block.
9594 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9595 COMPILE_FLAGS and added the --nostdinc option
9597 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9602 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9604 Documenting changes from previous commits.
9605 * configure.in (version 1.56),
9606 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9607 when generating output files to configure the pic16 library,
9608 but now I've commented it out, since gputils aren't installed in the
9609 SF compile farm, so library won't compile
9611 * device/lib/Makefile.in (version 1.56): initially I've added in
9612 target 'all' the prerequestive 'model-pic16' so it compiled the
9613 pic16 library, but now I've commented it out for the same reasons
9615 * added targets 'model-pic16' and 'objects-pic16' to compile the
9617 * added target 'port-specific-objects-pic16' to handle the
9618 generated libraries and copy them into the build/ directory
9619 * added target 'clean-intermediate-pic16' to clean intermediate
9620 files into pic16 directory
9621 * in target 'installdirs' added line to create directory pic16 in
9622 the installation path
9624 * device/include/Makefile.in (version 1.11): in target 'install'
9625 added lines to copy all header files to installation path,
9626 * in target 'installdirs' added line create directory for pic16
9627 headers in the installation path

9642 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9643 option so that it actually works. Made it specific to the z80, since
9644 the gbz80 doesn't have these kinds of I/O ports.
9646 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9648 * device/include/z180.h,

9661 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9663 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
9664 changed interrupt vector table generation to only emit declared vectors.

9670 Mainly changes to support compilation of the device libraries
9671 * src/pic16/device.c: stack is allocated via symbol and not
9672 via literal number. The symbol is placed in the corresponding
9673 position of the data ram
9674 * (pic16_dump_section): relocatable and absolute uninitialized
9675 data are now emitted in sorted order to reduce section naming,
9676 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9677 weren't marked as being in the access bank,
9679 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9681 Added portion of GNU PIC Library under the directory
9682 device/include/pic16 and device/lib/pic16. These files
9683 contain the declarations of SFRs for the PIC18Fxx2 devices.
9684 The directory is initialized via configure from toplevel.
9686 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9688 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9689 the spilllocations to be compared correctly
9691 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

9700 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9702 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
9703 in simpler and even better code

9713 * doc/sdccman.lyx: Moved and added some sections, small changes
9714 all over. Telling LaTeX to be less strict with word spacing
9715 to better keep the right margin. Changed some notes about
9716 maintainance of the ports in section 3.2.1 - is it OK like this?
9718 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9755 UPPER for immediate operands,
9756 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9758 * src/pic16/peeph.def: all peepholes with movff are commented out,
9759 because there is a problem in the pcode peep optimizer,
9760 * src/pic16/ralloc.c: the register allocator can now reuse local

9762 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9764 Added file src/pic16/NOTES with information about program writing on
9765 the current port version.

9822 override default uninitialized data segment definition for
9823 devices only with SHAREBANK memory (reported from Erik Epetrich)
9824 * (pic14emitOverlay): modified to emit a commented overlay segment
9825 directive when no overlay data exist
9826 * (picglue): modified to emit uninitialized data segment
9827 according to udata_section_name

9875 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9877 A python script to validate compiler diagnostic messages. It can be
9878 used to verify that sdcc complains about bad c source code and
9879 gives a good location of the error.
9880 * support/valdiag/Makefile,
9881 * support/valdiag/valdiag.py,
9882 * support/valdiag/tests/*

9899 Bug reported from Jesus Calvino-Fraga
9901 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9903 * sdcc.spec: updated
9904 * device/include/Makefile.in: don't install CVS directories

9909 * src/ds390/gen.c (genRightShift): fixed bug #870788
9910 * src/SDCCast.c (decorateType): fixed bug #870781
9912 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9914 PIC16 port related changes:
9915 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9916 added variable stackPos,
9918 * gen.c: genCall, assignResultValue: added support for
9919 pushing/retrieving function parameters to/from stack,
9920 genFunction,genEndFunction: setup stack frame for the
9922 genAddrOf: will be changed according to bug 863624
9924 * added files genutils.c and genutils.h which contain gen*
9925 debugged and optimised functions extracted from gen.c
9927 * glue.c: added variable 'externs' which holds extern symbols,
9928 pic16emitRegularMap: is modified to properly handle relocatable
9929 symbols under the new scheme,
9930 pic16createInterruptVect: is modified
9931 pic16printPublics: is modified to emit 'global' assembler directives,
9932 added pic16_printExterns to print extern symbols,
9933 pic16glue: initializes stack/frame pointer in the beginning of
9934 the assembly output. Temporary hack, will be corrected later,
9935 because gplink yet does not support stack and SDCC does not
9936 yet support a type of crt0.o object to create the final binary.
9938 * Removed many lines that contain 8051 legacy code.
9939 * The code is finally placed under a 'code' directive.
9940 * Added port specific options.
9942 * _process_pragma: simplified since now we do not need *special*
9943 include file to define SFR registers. But a separate header
9944 will be needed. This will be developed later.
9945 * _pic16_parseOptions: added, parses port specific options:
9946 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9947 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9948 --preplace-udata-with=
9950 * _pic16_setDefaultOptions: modified to initialize section names,
9951 but hack is temporarly out of order since it needs improvement.
9952 * _pic16_genAssemblerPreamble: configuration words are emitted by
9953 their address instead of their name. This part is incomplete and
9954 supports only the 18Fxx2 devices. Other devices will emit an error
9955 during assembly since they do not contain the same set of config
9957 * _pic16_genIVT: is modified,
9959 * pcode.c: added definitions for some hardware registers that are needed
9961 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9962 All PCI entries are updated. Now LFSR is supported.
9963 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9964 * added pic16_newpCodeOpLit2 to support instructions with
9965 two literal arguments
9966 * pic16_pCode2str: corrected code that emits assembler instructions
9967 with two literal operands and those that have an access bit modifier
9968 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9969 this fixes a bug which caused some labels to be lost, when an
9970 assembler directive was added, i.e. banksel,
9971 * pic16_FixRegisterBanking: improved logic that causes the insertion
9973 * InlineFunction: functions that are called once, are not any more
9974 inlined. This can be a port option in the future,
9976 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9978 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9979 hold the corresponding uninitialized symbols,
9980 * pic16_allocProcessorRegister: registers have explicit marked the
9982 * pic16_allocInternalRegister: registers are explicit marked as
9984 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9985 processing list, so bit registers were lost,
9988 * ralloc.h: added field 'accessBank' and original symbol operand
9989 in register definition,
9990 * removed the field isMapped from register definition,
9992 ** Several functions have been removed from various sources:
9993 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9994 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9995 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9996 pic16_assignRelocatableRegisters
9998 ** others have been introduced:
9999 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10000 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10002 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10004 * support/scripts/inc2h.pl: changed definition of BIT_AT
10005 to emit 'sbit at' instead of 'bit at'. This was a request.
10007 PIC16 port related preliminary changes:
10008 * gen.c: prefixed function popRegFromString with
10009 pic16_ and all references to it corrected
10010 * pcode.c: all pic16_pc_* hardware registers prefixed
10011 with underscore (_),
10012 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10013 * ralloc.c: newReg(): when register is REG_SFR then
10014 set address to rIdx,
10015 pic16_allocProcessorRegister(): marks register wasUsed=0
10016 pic16_writeUsedRegs(): added a call to assign processor
10017 registers via pic16_assignFixedRegisters
10019 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10021 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10022 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10023 variables in unused register banks. Also the SSEG is placed
10024 wherever there is enough space for it, and IDATA can be anywhere
10025 in internal RAM. For now compile using -Wl-Y[stack_size].
10026 The mem file is different for this option as well, since it
10027 makes no sense of talking about DSEG lenght.
10029 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

10278 it breaks with bitfields, extern declarations, and gcse analysis.
10279 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10280 could be assigned through a pointer, so don't complain.

11023 * src/mcs51/gen.c (leftRightUseAcc),
11024 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11025 iCode properly now. Use getSize instead of nRegs since a & b

11040 copied from genNearPointerSet()
11041 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11042 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11043 If they pop r0/r1 they must be called in the opposite order than aopOp().
11044 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11045 (resp. --stack-auto), prepared for --xstack
11047 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11056 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11058 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11059 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11060 type for bits was changed. It resulted in bit variables becoming
11061 global, which is not permitted in PIC 14 assembly output.
11063 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11065 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11067 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11069 Z80 and MCS51 linkers complaint if a public symbol is defined
11070 in more than one library module:
11074 * as/mcs51/Makefile.in
11076 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11078 A few small changes that speed up the peephole optimizer.
11082 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11084 Try to make the peephole optimizer smarter by maintaining
11085 an association between the assembly source code and the
11086 iCodes that originated them. Put this information to use
11087 with a new peephole rule condition "notVolatile" so that
11088 the rules can be aggressive yet still safe.
11093 * src/mcs51/peeph.def
11095 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11099 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11100 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11101 if the left or right operand symbols have the accuse flag set.
11103 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11105 Changed the type of the result of the ! (NOT) operator to char;
11106 previously it returned the same type as the source. This allows
11107 us to eliminate all the genFloatNot functions (all of its target
11108 implementations were very buggy) since !float can use the same
11111 * src/SDCCicode.c (ast2iCode): ! returns char
11112 * src/mcs51/gen.c (genNot, genNotFloat),
11113 * src/ds390/gen.c (genNot, genNotFloat),
11114 * src/z80/gen.c (genNot, genNotFloat),
11115 * src/pic/gen.c (genNot, genNotFloat),
11116 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11118 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11120 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11121 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11122 during interrupts. Ensure WSAVE is located at a shared bank address.
11123 2. Fixed page selection in some places
11124 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11125 the registers name strings.
11126 4. Fixed "signed / unsigned compare" compiler warnings.
11127 5. The PIC port manages its own allocation of the general purpose
11128 registers, but makes no attempt to reuse them. As a result when
11129 compiling it soon runs out of general purpose registers. Some
11130 additional code was added to the files pcode.c and device.c to walk
11131 through the function call tree and rename the registers so that they
11141 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11142 genPlus() & genMinus() when the result is the same as left or right
11144 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11146 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11148 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11150 Made bitfield a distinct type from bit so that bitfields
11151 convert as per ANSI C and bits retain their traditional
11152 boolean style behaviour. Implemented bitfield support in
11160 * src/ds390/gen.c: bit v bitfield split
11161 * src/z80/gen.c: New support for bitfields
11162 * support/regression/tests/bitfields.c: reenabled z80,
11165 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11167 Rules 246.x, 247.x relate to bitfields, the others speed up
11168 access to xdata mapped I/O devices.
11170 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11172 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11174 Cleaned up genPackBits and genUnpackBits and added two helper
11175 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11176 for literal assignments in genPackBits (thanks to Frieder for
11182 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11184 Fixed bug #748310 (pointer to function type mishandled when the
11185 function name is omitted). Also fixed a SIGSEGV when a function
11186 attribute (reentrant, etc) is used on a non-function or on a
11187 function but misplaced before the parameter list.
11189 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11191 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11192 * support/Util/SDCCerr.h,
11193 * support/Util/SDCCerr.c: Added func attr misuse error msg
11195 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11197 Fixed bug #787649 by anonymous
11198 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11199 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11201 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11203 Fixed numerous bitfield problems.
11205 * src/SDCC.y: More bitfield related error checking

11212 * support/regression/tests/bitfields.c: tests added
11214 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11216 Made the constant following the "interrupt" keyword optional. If
11217 omitted, the function will not automatically be given an entry
11218 in the interrupt vector table (similar to #pragma NOIV, but
11219 less syntacticly kludgy). The interrupt number is also now
11220 range checked. Also fixed a bug in the high order bit example
11227 * support/Util/SDCCerr.c
11228 * support/Util/SDCCerr.h
11231 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11233 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11234 * src/SDCCicode.c (operandOperation): rewritten some ops
11235 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11236 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11238 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11239 be re-activated by defining REDUCE_LITERALS)
11240 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11241 unsigned, but are signed by default
11242 * src/SDCCval.c (constVal): rearranged
11243 * src/SDCCval.c (valMod): preliminary fix
11244 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11282 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
11284 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11285 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11286 constants are unsigned; added recognition of "u" flag for unsigned
11287 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11288 * src/SDCCval.c (valDiv, valMod): fixed signdness
11289 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11290 signedness of modulo, left and right shift

11750 added if/endif conditional macros to remove options help
11751 messages from optionsTable when a port is not configured, added
11752 support for the PIc16 port in the ports table, when executing
11753 the compiler with no port specified on command line, a default
11754 port is selected with the new macro DEFAULT_PORT which is
11755 defined in port.h, in setDefaultOptions() linkOptions is removed
11756 from initialization assignment, since now it is a set,
11757 parseCmdLine uses setParseWithComma for linkOptions, in
11758 linkEdit() linkOptions are accessed with new function indexSet()
11759 which returns the i'th item of a set variable. See SDCCset.c, in
11760 linkEdit() when calling buildCmdLine(), added linkOptions as
11761 last argument. Now users can pass arguments to gplink via the
11762 -Wl option, main() uses pic16glue() to glue up pic16 programs

11776 gpasm complaining and test the linkage with gplink, _linkCmd and
11777 _asmCmd changed to be more gplink and gpasm friendly
11778 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11779 produced an error when parsed, peep rule 12 is added to utilize
11780 movff, but it is commented out since the pCode does not support
11781 yet a command with 2 address arguments
11783 2003-05-18 <johan AT balder>
11785 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12807 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
12808 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12809 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12810 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
12811 * src/pic/pcode.c: outcommented unused variable to remove warnings

12818 2003-01-06 <johan AT balder>
12820 * src/SDCCicode.c: fixed array add
12822 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12823 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12824 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12826 2003-01-04 <johan AT balder>
12828 * src/SDCCval.c (getNelements): fixed the initialized array of structures
12830 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12831 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12833 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12834 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12835 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12837 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12838 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12840 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12841 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12843 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12844 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12846 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12848 * in /sdcc/as/mcs51/ changed these files in order to create an
12849 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12850 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12851 following files to include the previous two files: aslink.dsp,
12852 Makefile.aslink, Makefile.bcc, and Makefile.in.
12854 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12855 .adb instead of .cdb
12857 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12859 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12860 value from option --iram-size.
12862 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12864 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12867 2002-09-18 <wiml AT hhhh.org>
12869 * SDCClrange.h: exposed setFromRange() and setToRange()
12870 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12871 packRegsForAccUse() (bug 542397)
12872 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12873 multiple times and emitting the fetch operations more than once
12874 added aopGetUsesAcc() function to allow binary operators to
12875 fetch their operands in the correct order; made genMinus() emit
12876 compact code for X = LITERAL - Y
12878 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12879 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12880 sprintf() in line 1267.
12882 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12883 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12886 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12887 Changes to aslink (All the changes are marked with 'JCF'):
12889 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12892 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12893 area BSEG. Also moves, if possible, the DATA area down into the internal
12894 ram so more space is available.
12896 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12899 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12900 not bytes. Function summary() which creates a memory usage summary
12901 file with extension .mem. Reports of overlaping stack and small stack
12902 size. If the space for the stack is less than 16 bytes aslink trows a
12905 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12906 the 8051. Option 'y' for memory summary output file.
12908 Changes to sdcc (All the changes are marked with 'JCF'):
12910 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12912 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12913 overlaying area for it (uses RegBankUsed[4]).
12915 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12916 bank zero as used by default. By default aslink locates the stack
12917 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12918 the creation of the .mem file. Delegates the allocation of data area
12919 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12920 the begining of the stack area to aslink.
12922 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12923 glue() in SDCCglue.c creates an area for it.
12925 2002-09-03 Borut Razem <borut.razem AT siol.net>
12926 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12927 sdcc/src/pic/glue.c:
12928 introduced atexit() handler for teporay files removal in case of
12929 errors, assertions, ...
12931 2002-08-29 Borut Razem <borut.razem AT siol.net>
12932 * sdcc/support/cpp2/auto-host_vc_in.h:
12933 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12934 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12935 Maybe there is a similar problem with BORLANDC? It should be checked!
12937 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12938 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12939 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12940 was not executed, and the compiler (cl) launched a warning:
12941 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12943 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12944 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12946 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12947 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12949 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12950 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12951 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12952 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12953 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12954 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12955 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12956 - added Release configuration in VS projects
12957 - review of compiler an linker options
12958 - VC .exe files are generated in bin_vc directory, not to interfere
12959 with binaries generated from other projects (cygwin, mingw, bcc ...)
12961 * sdcc/src/yacc.dsp: added
12963 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12964 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12965 and insert the version number definitions from .version
12967 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12969 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12970 added - genarate auto-host.h using auto-host_vc_in.h as template
12973 removed from CVS, generated automatically
12975 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12976 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12978 2002-08-11 Borut Razem <borut.razem AT siol.net>
12979 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12981 2002-08-10 Borut Razem <borut.razem AT siol.net>
12982 * src/SDCCmain.c (main):
12983 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12984 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12985 The consequence was that some temporary files were not removed.
12988 unification of code in functions tempfilename() and tempfile():
12989 function tempnam() is defined in Visual Studio 6.0 and .NET
12991 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12993 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12994 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12995 - removed compiler command line option /WX: Treats all warnings as errors
12996 - update a list of source files, included into the project
12998 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12999 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13000 changed project type to Generic Project so that can be correcly converted to VS.NET project
13002 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13004 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13006 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13008 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13009 added return 0 statements after assert() to make compiler happy
13011 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13012 added newline in the def file to keep MSC compiler satisfied
13014 * sdcc/src/z80/gen.c:
13015 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13016 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13017 - solved MSC error in function aopDump()
13019 * sdcc_vc.h: define PREFIX as "\\sdcc"
13021 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13022 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13025 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13026 - Rewrote the register banking algorithm.
13027 - Added pCode live-range analysis to registers (for now, only non-used and
13028 singly-used registers optimized away)
13030 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13032 * 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.

13055 * src/z80/main.c: Added force callee saves for jaune.
13057 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13059 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13061 2002-03-28 Johan Knol <johan AT balder>
13063 * src/SDCCval.c: fixed bug #532436
13065 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13067 Added "char *Processor" field to the port structure.
13070 Added -p option. Allows port dependent processor to be specified.
13073 Initialized the new field char *Processor field to NULL in all ports
13076 Compiler generated registers for interrupt context saving
13077 were not getting allocated.
13079 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13082 Fixed left shift. Will promote the left side of a left shift
13083 if a) left shifting more than size of operand or b) when assigned
13084 to something size > size of left side
13086 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13088 tons of changes. Register allocation has been
13089 rewritten. Added customization for the various PICs. Flow
13090 analysis is restructured. ...
13092 * src/pic/device.h:
13095 * src/pic/device.c:
13096 Added. device.c is a PIC port hack to accomodate variations
13099 2002-03-13 Michael Hope <michaelh AT vroom>
13101 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13103 2002-03-04 johanknol <johanknol AT manik>
13105 * /src/SDCCval.c: fixed
13107 const unsigned char arr[][2] = { { 0, 1 } };

13194 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13196 * sdcc/src/SDCCloop.c:
13197 Previous fix was not good. basic blocks that have "break" or "return" are
13198 not really partof a loop , but live ranges used in these blocks should
13199 be live thru the entire loop, so set partOfLoop but don't add them to
13202 2002-02-21 <johan AT FRIJA>
13204 * src/SDCCcse.c: fixed bug #514308
13206 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13209 Fixed BUG #519583. If a conditional block ended in a return/break
13210 statement inside a loop, it was not being considered part of the loop.
13212 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
13214 2002-02-10 Karl Bongers <karl AT turbobit.com>

13220 * device/examples/test2.c:
13221 Fix bug, "red" variable not being initialized(compiler complained).
13223 * device/examples/Makefile, examples/test3.c:
13224 Add Makefile in device/examples folder, compiles test3.c
13225 for use as a multiple module SDCDB test case.
13227 * sim/ucsim/cmd.src/cmdset.cc:
13228 Took out debug printfs in ucsim "next" command.
13230 * sim/ucsim/xa.src:
13231 Karl and Johan start ucsim XA support. Most dissassembly working,
13232 about 75% emulation done(plenty of work remaining).
13234 * sim/ucsim/z80.src:
13235 Add Z80 support to ucsim, add test-ucz80 regression test,
13236 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
13237 Notice z80 compiler fails on examples/test3.c/crc code.
13239 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
13241 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

13251 3) added __builtin_swapw swap bytes of a short
13253 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
13254 1) handle multiple send & receives from register bank1
13255 2) ralloc can now allocate DPTR1 to some liveRanges
13257 * src/SDCCsymt.c, src/SDCCsymt.h:
13258 changes to handle multiple sends & receives
13260 * src/SDCCptropt.h:
13261 added some pointer arithmetic optimization
13263 * src/SDCCptropt.c:
13264 added some pointer arithmetic optimizations but not stable yet so not
13265 called from anywhere (will get this working shortly)
