172 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
175 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
177 * src/.version: increased version number to 2.5.5
178 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
179 linking is done manually in pic16 port's _linkEdit,
180 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
181 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

261 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
262 which dumps before the function entry point a data byte which represents
263 the number of the local variables used by the specified function, added
264 'xinst' for initial support for Extended Instruction Support,
265 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
266 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
267 port->fun_prefix anymore (may change later),
268 (genFunction, genEndFunction): do not store/restore local registers for
269 _main (this should take care the --main-return command line option in
271 (genOr): removed some legacy pic-port instructions,
272 * src/pic16/genarith.c (genAddLit): re-enabled old code because
273 performing operations with SFR's causes data to be written more than
274 once to each SFR. Perhaps SFRs should be handled in special cases...
275 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
277 * src/pic16/main.c (_process_pragma): stack bound checking did not take
278 into account for stack starting position,
279 (struct OPTIONS pic16_optionsTable): added command line argument
280 --extended or -y for Extended Instruction Support,
281 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
282 (deassignLRs): *** perhaps the most important change, old 'for' code
283 (commented out for reference), didn't account for some registers which
284 were left marked 'not free' after a pointer operation. The change
285 reduces register usage a lot in some cases

2577 2005-03-21 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2579 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
2582 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2584 * src/port.h (struct PORT),

2610 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
2611 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2612 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2613 immedDom() returning wrong block; probably fixes bug #1160833)
2615 2005-03-20 Borut Razem <borut.razem AT siol.net>
2617 * support/scripts/inc2h.pl: WIN32 port
2619 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2621 * device/lib/makefile.in: added abs.c and labs.c
2623 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2625 * device/include/stdint.h: added
2626 * device/lib/abs.c: added
2627 * device/lib/labs.c: added
2628 * device/include/stdlib.h: added abs() and labs() prototypes
2629 * device/lib/libsdcc.lib: added abs and labs
2630 * device/include/float.h,
2631 * device/lib/_fsmul.c,
2632 * device/lib/printf_fast.c,

2635 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2637 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2640 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2643 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2645 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2647 * device/lib/printf_large.c: removed inline assembly for portability and
2648 readability. Use printf_fast if speed or size are more important.
2649 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2650 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2652 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2654 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2655 prevent compiler warning
2657 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2659 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2660 moved to level 0 and declared as static. Also they are explicit
2661 placed in access bank. This was necessery because some times they
2662 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2663 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2664 optimizations. Currently only compare to unsigned char is implemented,
2665 * src/pic16/gen.c: added fReturnIdx array,
2666 * (struct resolvedIfx) is moved to gen.h and made public,
2667 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2668 * (aopForSym): added an optimization to directly store in stack of
2669 the operand of a SEND iCode,
2670 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2671 but as registers instead (AOP_REG) using the fReturnIdx array,
2672 * (pic16_freeAsmop): remove the freed register from the
2673 _G.sregsAlloc field,
2674 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2675 a compare of 'WREG',
2676 * (pic16_popGetTempRegCond): changed function prototype, now
2677 function takes also a bitVector argument v which holds the current
2678 set of registers that are allocated for stack access by aopForSym,
2679 registers allocated in aopForSym for accessing stack symbols are not
2680 any more part of the functions usedRegs field,
2681 * (genCall): some times aopOp is called for a stack variable to be
2682 send, aopForSym might perform the push, if this is true make sure
2683 that genCall doesn't push the variable twice by testing _G.resDirect,
2684 * (genFunction): changed testing for unspecified interrupt number
2685 from 256 to INTNO_UNSPEC,
2686 * modified selection scheme of frame pointer generation. Previously
2687 if function did use local registers a frame pointer was generated,
2688 now a frame pointer is generated only if function has arguments
2689 (that need PLUSW2 register access), or has stack arguments, or the
2690 compiler is not instructed to omit the frame pointer,
2691 * (genEndFunction): before restoring local registers that were saved
2692 in the function preamble, also restore the registers that *might*
2693 have been allocated for stack access,
2694 * (genRet): removed some old comments,
2695 * (genCmp, the active (RN's) version): added a call to the
2696 pic16_genCmp_special function to perform the compare with a more
2697 robust and optimized way,
2698 * (genInline): a feature has been added in inline code generation,
2699 which allows a wildcard variable substitution when writing inline
2700 assembly. Code is incomplete and experimental therefore undocumented,
2701 * (genCast): changed order of aopOp for result and right to allow
2702 aopForSym to directly load the result if possible,
2703 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2704 perform an optimized compare on some selected special occasions,
2705 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2706 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2707 generate an IVT any more,
2708 * src/pic16/main.c (pic16_optionsTable): added command line option
2710 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2711 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2713 * src/pic16/NOTES: Raphael Neider added in list of active developers
2714 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2715 jumptable_end to prevent bug #,
2716 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2717 inCond and outCond fields,
2718 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2719 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2720 turn off register spilling,
2721 * (packRegsForOneUse): synced with other ports' versions although it
2722 is not used currently,
2723 * (pic16_packRegisters): added an optimization while reading
2724 structure bitfields, some registers may be saved (malloc code is
2725 decreased by 80 bytes)
2727 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2729 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2730 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2731 this can be optimized more?
2733 2005-03-10 Raphael Neider <rneider AT web.de>
2735 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2736 genNearPointerGet): (hopefully) fixed access to bitfields via
2737 pointers (p->bitN = x; and x = p->bitN; failed)
2739 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2741 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2780 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2782 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2783 to keep the correct label reference count when adding/removing references
2784 to labels. A peephole file using this is appended to patch #1144962.

2926 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2927 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2928 this might fix SIGSEGVs on MinGW...
2929 * src/SDCCopt.c (killDeadCode): restored original behaviour
2930 (volatile operands might get thrown away though)
2932 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2986 the first pCode is used
2988 2005-01-22 Raphael Neider <rneider AT web.de>
2990 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): disabled optimization

3016 * (genUminus): rewritten to for efficiency
3017 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
3018 used uninitialized in some cases)
3019 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
3020 copy the third byte from the int -- now assumes 0x80 (data memory)
3021 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
3022 operands (genAddLit expects the iCode's operands to swapped as
3023 well), fixed leftover bytes (crashed for short left operands)

3372 generated for switch statements. For now you need to set the
3373 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3374 Now 4 algorithms for mcs51 jumptable generation are used:
3375 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3409 * added libc directory. The current version of LibC contains string
3410 functions, ctype functions and macros and some functions of the
3411 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3412 be extensively tested in the future. Standard disclaimer here.
3413 Library is not automatically build yet. But one can build it by
3414 invoking 'make' inside the libc directory.

3424 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3425 * (pic16_storeForReturn): optimized return of 0,
3426 * (genCmp): experimental code for new genCmp which uses PIC18's
3427 special compare&skip instructions. Initial tests fail some times
3428 with variables grater than 1 byte in size, so new code is disabled,
3429 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3431 * (genCast): began a fix to optimize the casting of a bit to another
3432 bit, now assigning a bitfield to another bitfield will fail, sorry,

3438 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3440 * (isBankInstruction): modified to return 0 for no banking instruction,
3441 and 1 for banking instruction,
3442 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3443 caused stop processing pCodes after a inline assembly block,
3444 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3445 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3446 registers when it shouldn't,
3447 * src/pic16/ralloc.c (allocReg): add preliminary support for

6455 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6457 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6458 loaded with the linker search paths (-L arguments) and the libraries
6459 to be linked with the current source (-l arguments). Changes
6460 currently will affect only the pic16 port.
6461 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6462 include path the port specific paths and port specific libraries,
6463 * gplink command now contains the $3 argument,
6464 * src/pic16/device.h,
6465 * src/pic16/device.c,: structure PIC_device is made public and
6466 renamed to PIC16_device, the same for variable Pics which is renamed

6481 Documenting changes from previous commits.
6482 * configure.in (version 1.56),
6483 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6484 when generating output files to configure the pic16 library,
6485 but now I've commented it out, since gputils aren't installed in the
6486 SF compile farm, so library won't compile
6488 * device/lib/Makefile.in (version 1.56): initially I've added in
6489 target 'all' the prerequestive 'model-pic16' so it compiled the
6490 pic16 library, but now I've commented it out for the same reasons
6492 * added targets 'model-pic16' and 'objects-pic16' to compile the
6494 * added target 'port-specific-objects-pic16' to handle the
6495 generated libraries and copy them into the build/ directory
6496 * added target 'clean-intermediate-pic16' to clean intermediate
6497 files into pic16 directory
6498 * in target 'installdirs' added line to create directory pic16 in
6499 the installation path
6501 * device/include/Makefile.in (version 1.11): in target 'install'
6502 added lines to copy all header files to installation path,
6503 * in target 'installdirs' added line create directory for pic16
6504 headers in the installation path

6519 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6520 option so that it actually works. Made it specific to the z80, since
6521 the gbz80 doesn't have these kinds of I/O ports.
6523 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6525 * device/include/z180.h,

6549 via literal number. The symbol is placed in the corresponding
6550 position of the data ram
6551 * (pic16_dump_section): relocatable and absolute uninitialized
6552 data are now emitted in sorted order to reduce section naming,
6553 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6554 weren't marked as being in the access bank,
6556 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6558 Added portion of GNU PIC Library under the directory
6559 device/include/pic16 and device/lib/pic16. These files
6560 contain the declarations of SFRs for the PIC18Fxx2 devices.
6561 The directory is initialized via configure from toplevel.

6591 all over. Telling LaTeX to be less strict with word spacing
6592 to better keep the right margin. Changed some notes about
6593 maintainance of the ports in section 3.2.1 - is it OK like this?
6595 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6635 * src/pic16/peeph.def: all peepholes with movff are commented out,
6636 because there is a problem in the pcode peep optimizer,
6637 * src/pic16/ralloc.c: the register allocator can now reuse local

6747 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6749 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6750 (default behaviour).
6752 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6754 A python script to validate compiler diagnostic messages. It can be
6755 used to verify that sdcc complains about bad c source code and
6756 gives a good location of the error.
6757 * support/valdiag/Makefile,
6758 * support/valdiag/valdiag.py,
6759 * support/valdiag/tests/*

6776 Bug reported from Jesus Calvino-Fraga
6778 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6780 * sdcc.spec: updated
6781 * device/include/Makefile.in: don't install CVS directories
6782 * device/lib/Makefile.in: added removal of CVS directories after install
6783 * doc/Makefile: fixed install, added local_icons
6784 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6785 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6786 * src/ds390/gen.c (genRightShift): fixed bug #870788
6787 * src/SDCCast.c (decorateType): fixed bug #870781
6789 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6791 PIC16 port related changes:
6792 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6793 added variable stackPos,
6795 * gen.c: genCall, assignResultValue: added support for
6796 pushing/retrieving function parameters to/from stack,
6797 genFunction,genEndFunction: setup stack frame for the
6799 genAddrOf: will be changed according to bug 863624
6801 * added files genutils.c and genutils.h which contain gen*
6802 debugged and optimised functions extracted from gen.c
6804 * glue.c: added variable 'externs' which holds extern symbols,
6805 pic16emitRegularMap: is modified to properly handle relocatable
6806 symbols under the new scheme,
6807 pic16createInterruptVect: is modified
6808 pic16printPublics: is modified to emit 'global' assembler directives,
6809 added pic16_printExterns to print extern symbols,
6810 pic16glue: initializes stack/frame pointer in the beginning of
6811 the assembly output. Temporary hack, will be corrected later,
6812 because gplink yet does not support stack and SDCC does not
6813 yet support a type of crt0.o object to create the final binary.
6815 * Removed many lines that contain 8051 legacy code.
6816 * The code is finally placed under a 'code' directive.
6817 * Added port specific options.
6819 * _process_pragma: simplified since now we do not need *special*
6820 include file to define SFR registers. But a separate header
6821 will be needed. This will be developed later.
6822 * _pic16_parseOptions: added, parses port specific options:
6823 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6824 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6825 --preplace-udata-with=
6827 * _pic16_setDefaultOptions: modified to initialize section names,
6828 but hack is temporarly out of order since it needs improvement.
6829 * _pic16_genAssemblerPreamble: configuration words are emitted by
6830 their address instead of their name. This part is incomplete and
6831 supports only the 18Fxx2 devices. Other devices will emit an error
6832 during assembly since they do not contain the same set of config
6834 * _pic16_genIVT: is modified,
6836 * pcode.c: added definitions for some hardware registers that are needed
6838 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6839 All PCI entries are updated. Now LFSR is supported.
6840 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6841 * added pic16_newpCodeOpLit2 to support instructions with
6842 two literal arguments
6843 * pic16_pCode2str: corrected code that emits assembler instructions
6844 with two literal operands and those that have an access bit modifier
6845 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6846 this fixes a bug which caused some labels to be lost, when an
6847 assembler directive was added, i.e. banksel,
6848 * pic16_FixRegisterBanking: improved logic that causes the insertion
6850 * InlineFunction: functions that are called once, are not any more
6851 inlined. This can be a port option in the future,
6853 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6855 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6856 hold the corresponding uninitialized symbols,
6857 * pic16_allocProcessorRegister: registers have explicit marked the
6859 * pic16_allocInternalRegister: registers are explicit marked as
6861 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6862 processing list, so bit registers were lost,
6865 * ralloc.h: added field 'accessBank' and original symbol operand
6866 in register definition,
6867 * removed the field isMapped from register definition,
6869 ** Several functions have been removed from various sources:
6870 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6871 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6872 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6873 pic16_assignRelocatableRegisters
6875 ** others have been introduced:
6876 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6877 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6879 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6881 * support/scripts/inc2h.pl: changed definition of BIT_AT
6882 to emit 'sbit at' instead of 'bit at'. This was a request.
6884 PIC16 port related preliminary changes:
6885 * gen.c: prefixed function popRegFromString with
6886 pic16_ and all references to it corrected
6887 * pcode.c: all pic16_pc_* hardware registers prefixed
6888 with underscore (_),
6889 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6890 * ralloc.c: newReg(): when register is REG_SFR then
6891 set address to rIdx,
6892 pic16_allocProcessorRegister(): marks register wasUsed=0
6893 pic16_writeUsedRegs(): added a call to assign processor
6894 registers via pic16_assignFixedRegisters
6896 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6898 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6899 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6900 variables in unused register banks. Also the SSEG is placed
6901 wherever there is enough space for it, and IDATA can be anywhere
6902 in internal RAM. For now compile using -Wl-Y[stack_size].
6903 The mem file is different for this option as well, since it
6904 makes no sense of talking about DSEG lenght.
6906 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6908 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6909 in certain cases, e.g. when ROM assignment, patch provided
6910 from Albert den Haan.
6912 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7054 SDCC_NOGENRAMCLEAR to disable this.
7055 * src/mcs51/peephole.def,
7056 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7057 (allows non-interrupt and interrupt code to safely compete for a resource
7058 without the non-interrupt code having to disable interrupts)
7060 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7062 * src/SDCCicode.c (geniCodeAdd),

7935 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7936 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7937 type for bits was changed. It resulted in bit variables becoming

7955 A few small changes that speed up the peephole optimizer.
7959 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7961 Try to make the peephole optimizer smarter by maintaining
7962 an association between the assembly source code and the
7963 iCodes that originated them. Put this information to use
7964 with a new peephole rule condition "notVolatile" so that
7965 the rules can be aggressive yet still safe.
7970 * src/mcs51/peeph.def
7972 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7976 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7977 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7978 if the left or right operand symbols have the accuse flag set.
7980 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7982 Changed the type of the result of the ! (NOT) operator to char;
7983 previously it returned the same type as the source. This allows
7984 us to eliminate all the genFloatNot functions (all of its target
7985 implementations were very buggy) since !float can use the same
7988 * src/SDCCicode.c (ast2iCode): ! returns char

7997 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7998 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7999 during interrupts. Ensure WSAVE is located at a shared bank address.
8000 2. Fixed page selection in some places
8001 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8002 the registers name strings.
8003 4. Fixed "signed / unsigned compare" compiler warnings.
8004 5. The PIC port manages its own allocation of the general purpose
8005 registers, but makes no attempt to reuse them. As a result when
8006 compiling it soon runs out of general purpose registers. Some
8007 additional code was added to the files pcode.c and device.c to walk
8008 through the function call tree and rename the registers so that they
8018 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8025 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8027 Made bitfield a distinct type from bit so that bitfields
8028 convert as per ANSI C and bits retain their traditional
8029 boolean style behaviour. Implemented bitfield support in
8037 * src/ds390/gen.c: bit v bitfield split
8038 * src/z80/gen.c: New support for bitfields
8039 * support/regression/tests/bitfields.c: reenabled z80,
8042 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8044 Rules 246.x, 247.x relate to bitfields, the others speed up
8045 access to xdata mapped I/O devices.
8047 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8049 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8051 Cleaned up genPackBits and genUnpackBits and added two helper
8052 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8053 for literal assignments in genPackBits (thanks to Frieder for
8059 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8061 Fixed bug #748310 (pointer to function type mishandled when the
8062 function name is omitted). Also fixed a SIGSEGV when a function
8063 attribute (reentrant, etc) is used on a non-function or on a
8064 function but misplaced before the parameter list.
8066 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8068 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8069 * support/Util/SDCCerr.h,

8091 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8093 Made the constant following the "interrupt" keyword optional. If
8094 omitted, the function will not automatically be given an entry
8095 in the interrupt vector table (similar to #pragma NOIV, but
8096 less syntacticly kludgy). The interrupt number is also now
8097 range checked. Also fixed a bug in the high order bit example
8104 * support/Util/SDCCerr.c
8105 * support/Util/SDCCerr.h

8627 added if/endif conditional macros to remove options help
8628 messages from optionsTable when a port is not configured, added
8629 support for the PIc16 port in the ports table, when executing
8630 the compiler with no port specified on command line, a default
8631 port is selected with the new macro DEFAULT_PORT which is
8632 defined in port.h, in setDefaultOptions() linkOptions is removed
8633 from initialization assignment, since now it is a set,
8634 parseCmdLine uses setParseWithComma for linkOptions, in
8635 linkEdit() linkOptions are accessed with new function indexSet()
8636 which returns the i'th item of a set variable. See SDCCset.c, in
8637 linkEdit() when calling buildCmdLine(), added linkOptions as

9697 * src/SDCCicode.c: fixed array add
9699 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9700 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9701 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9703 2003-01-04 <johan AT balder>
9705 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9707 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9708 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9710 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9711 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9718 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9720 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9721 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9723 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9725 * in \sdcc\as\mcs51\ changed these files in order to create an
9726 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9727 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9728 following files to include the previous two files: aslink.dsp,
9729 Makefile.aslink, Makefile.bcc, and Makefile.in.
9731 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9732 .adb instead of .cdb
9734 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9736 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9737 value from option --iram-size.
9739 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9741 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9744 2002-09-18 <wiml AT hhhh.org>
9746 * SDCClrange.h: exposed setFromRange() and setToRange()
9747 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9748 packRegsForAccUse() (bug 542397)
9749 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9750 multiple times and emitting the fetch operations more than once
9751 added aopGetUsesAcc() function to allow binary operators to
9752 fetch their operands in the correct order; made genMinus() emit
9753 compact code for X = LITERAL - Y
9755 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9756 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9757 sprintf() in line 1267.
9759 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9760 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9763 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9764 Changes to aslink (All the changes are marked with 'JCF'):
9766 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9769 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9770 area BSEG. Also moves, if possible, the DATA area down into the internal
9771 ram so more space is available.
9773 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9776 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9777 not bytes. Function summary() which creates a memory usage summary
9778 file with extension .mem. Reports of overlaping stack and small stack
9779 size. If the space for the stack is less than 16 bytes aslink trows a
9782 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9783 the 8051. Option 'y' for memory summary output file.
9785 Changes to sdcc (All the changes are marked with 'JCF'):
9787 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9789 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9790 overlaying area for it (uses RegBankUsed[4]).
9792 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9793 bank zero as used by default. By default aslink locates the stack
9794 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9795 the creation of the .mem file. Delegates the allocation of data area
9796 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9797 the begining of the stack area to aslink.
9799 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9800 glue() in SDCCglue.c creates an area for it.
9802 2002-09-03 Borut Razem <borut.razem AT siol.net>
9803 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9804 sdcc/src/pic/glue.c:
9805 introduced atexit() handler for teporay files removal in case of
9806 errors, assertions, ...
9808 2002-08-29 Borut Razem <borut.razem AT siol.net>
9809 * sdcc/support/cpp2/auto-host_vc_in.h:
9810 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9811 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9812 Maybe there is a similar problem with BORLANDC? It should be checked!
9814 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9815 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9816 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9817 was not executed, and the compiler (cl) launched a warning:
9818 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9820 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9821 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9823 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9824 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9826 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9827 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9828 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9829 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9830 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9831 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9832 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9833 - added Release configuration in VS projects
9834 - review of compiler an linker options
9835 - VC .exe files are generated in bin_vc directory, not to interfere
9836 with binaries generated from other projects (cygwin, mingw, bcc ...)
9838 * sdcc/src/yacc.dsp: added
9840 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9841 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9842 and insert the version number definitions from .version
9844 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9846 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9847 added - genarate auto-host.h using auto-host_vc_in.h as template
9850 removed from CVS, generated automatically
9852 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9853 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9855 2002-08-11 Borut Razem <borut.razem AT siol.net>
9856 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9858 2002-08-10 Borut Razem <borut.razem AT siol.net>
9859 * src/SDCCmain.c (main):
9860 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9861 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9862 The consequence was that some temporary files were not removed.
9865 unification of code in functions tempfilename() and tempfile():
9866 function tempnam() is defined in Visual Studio 6.0 and .NET
9868 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9870 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9871 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9872 - removed compiler command line option /WX: Treats all warnings as errors
9873 - update a list of source files, included into the project
9875 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9876 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9877 changed project type to Generic Project so that can be correcly converted to VS.NET project
9879 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9881 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9883 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9885 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9886 added return 0 statements after assert() to make compiler happy
9888 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9889 added newline in the def file to keep MSC compiler satisfied
9891 * sdcc/src/z80/gen.c:
9892 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9893 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9894 - solved MSC error in function aopDump()
9896 * sdcc_vc.h: define PREFIX as "\\sdcc"
9898 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9899 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9901 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9902 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9903 - Rewrote the register banking algorithm.
9904 - Added pCode live-range analysis to registers (for now, only non-used and
9905 singly-used registers optimized away)
9907 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9909 * 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.
9911 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9912 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9914 2002-04-22 Michael Hope <michaelh AT vroom>

9930 * src/z80/peeph.def: Added transpose redundent load rule.
9932 * src/z80/main.c: Added force callee saves for jaune.
9934 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9936 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9938 2002-03-28 Johan Knol <johan AT balder>
9940 * src/SDCCval.c: fixed bug #532436
9942 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9944 Added "char *Processor" field to the port structure.
9947 Added -p option. Allows port dependent processor to be specified.
9950 Initialized the new field char *Processor field to NULL in all ports
9953 Compiler generated registers for interrupt context saving
9954 were not getting allocated.
9956 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9959 Fixed left shift. Will promote the left side of a left shift
9960 if a) left shifting more than size of operand or b) when assigned
