157 the left operand is shorter than the result (c* = lit-c* + int),
159 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
162 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
164 * src/.version: increased version number to 2.5.5
165 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
166 linking is done manually in pic16 port's _linkEdit,
167 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
168 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

2597 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
2598 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2599 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2600 immedDom() returning wrong block; probably fixes bug #1160833)
2602 2005-03-20 Borut Razem <borut.razem AT siol.net>
2604 * support/scripts/inc2h.pl: WIN32 port
2606 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2608 * device/lib/makefile.in: added abs.c and labs.c
2610 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2612 * device/include/stdint.h: added
2613 * device/lib/abs.c: added
2614 * device/lib/labs.c: added
2615 * device/include/stdlib.h: added abs() and labs() prototypes
2616 * device/lib/libsdcc.lib: added abs and labs
2617 * device/include/float.h,
2618 * device/lib/_fsmul.c,
2619 * device/lib/printf_fast.c,
2620 * device/lib/printf_tiny.c: updated comments
2622 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2624 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2627 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2629 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2630 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2632 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2634 * device/lib/printf_large.c: removed inline assembly for portability and
2635 readability. Use printf_fast if speed or size are more important.
2636 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2637 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2639 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2641 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2642 prevent compiler warning
2644 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2646 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2647 moved to level 0 and declared as static. Also they are explicit
2648 placed in access bank. This was necessery because some times they
2649 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2650 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2651 optimizations. Currently only compare to unsigned char is implemented,
2652 * src/pic16/gen.c: added fReturnIdx array,
2653 * (struct resolvedIfx) is moved to gen.h and made public,
2654 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2655 * (aopForSym): added an optimization to directly store in stack of
2656 the operand of a SEND iCode,
2657 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2658 but as registers instead (AOP_REG) using the fReturnIdx array,
2659 * (pic16_freeAsmop): remove the freed register from the
2660 _G.sregsAlloc field,
2661 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2662 a compare of 'WREG',
2663 * (pic16_popGetTempRegCond): changed function prototype, now
2664 function takes also a bitVector argument v which holds the current
2665 set of registers that are allocated for stack access by aopForSym,
2666 registers allocated in aopForSym for accessing stack symbols are not
2667 any more part of the functions usedRegs field,
2668 * (genCall): some times aopOp is called for a stack variable to be
2669 send, aopForSym might perform the push, if this is true make sure
2670 that genCall doesn't push the variable twice by testing _G.resDirect,
2671 * (genFunction): changed testing for unspecified interrupt number
2672 from 256 to INTNO_UNSPEC,
2673 * modified selection scheme of frame pointer generation. Previously
2674 if function did use local registers a frame pointer was generated,
2675 now a frame pointer is generated only if function has arguments
2676 (that need PLUSW2 register access), or has stack arguments, or the
2677 compiler is not instructed to omit the frame pointer,
2678 * (genEndFunction): before restoring local registers that were saved
2679 in the function preamble, also restore the registers that *might*
2680 have been allocated for stack access,
2681 * (genRet): removed some old comments,
2682 * (genCmp, the active (RN's) version): added a call to the
2683 pic16_genCmp_special function to perform the compare with a more
2684 robust and optimized way,
2685 * (genInline): a feature has been added in inline code generation,
2686 which allows a wildcard variable substitution when writing inline
2687 assembly. Code is incomplete and experimental therefore undocumented,
2688 * (genCast): changed order of aopOp for result and right to allow
2689 aopForSym to directly load the result if possible,
2690 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2691 perform an optimized compare on some selected special occasions,
2692 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2693 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2694 generate an IVT any more,
2695 * src/pic16/main.c (pic16_optionsTable): added command line option
2697 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2698 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2700 * src/pic16/NOTES: Raphael Neider added in list of active developers
2701 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2702 jumptable_end to prevent bug #,
2703 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2704 inCond and outCond fields,
2705 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2706 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2707 turn off register spilling,
2708 * (packRegsForOneUse): synced with other ports' versions although it
2709 is not used currently,
2710 * (pic16_packRegisters): added an optimization while reading
2711 structure bitfields, some registers may be saved (malloc code is
2712 decreased by 80 bytes)
2714 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2716 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2717 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2718 this can be optimized more?
2720 2005-03-10 Raphael Neider <rneider AT web.de>
2722 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2723 genNearPointerGet): (hopefully) fixed access to bitfields via
2724 pointers (p->bitN = x; and x = p->bitN; failed)
2726 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2914 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2915 this might fix SIGSEGVs on MinGW...

3004 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
3005 used uninitialized in some cases)

3397 functions, ctype functions and macros and some functions of the
3398 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3399 be extensively tested in the future. Standard disclaimer here.

3414 special compare&skip instructions. Initial tests fail some times
3415 with variables grater than 1 byte in size, so new code is disabled,
3416 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3418 * (genCast): began a fix to optimize the casting of a bit to another
3419 bit, now assigning a bitfield to another bitfield will fail, sorry,

6442 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6444 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6445 loaded with the linker search paths (-L arguments) and the libraries
6446 to be linked with the current source (-l arguments). Changes
6447 currently will affect only the pic16 port.
6448 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6449 include path the port specific paths and port specific libraries,
6450 * gplink command now contains the $3 argument,
6451 * src/pic16/device.h,
6452 * src/pic16/device.c,: structure PIC_device is made public and
6453 renamed to PIC16_device, the same for variable Pics which is renamed

6468 Documenting changes from previous commits.
6469 * configure.in (version 1.56),
6470 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6471 when generating output files to configure the pic16 library,
6472 but now I've commented it out, since gputils aren't installed in the
6473 SF compile farm, so library won't compile
6475 * device/lib/Makefile.in (version 1.56): initially I've added in
6476 target 'all' the prerequestive 'model-pic16' so it compiled the
6477 pic16 library, but now I've commented it out for the same reasons
6479 * added targets 'model-pic16' and 'objects-pic16' to compile the
6481 * added target 'port-specific-objects-pic16' to handle the
6482 generated libraries and copy them into the build/ directory
6483 * added target 'clean-intermediate-pic16' to clean intermediate
6484 files into pic16 directory
6485 * in target 'installdirs' added line to create directory pic16 in
6486 the installation path
6488 * device/include/Makefile.in (version 1.11): in target 'install'
6489 added lines to copy all header files to installation path,
6490 * in target 'installdirs' added line create directory for pic16
6491 headers in the installation path

6506 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6507 option so that it actually works. Made it specific to the z80, since
6508 the gbz80 doesn't have these kinds of I/O ports.
6510 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6512 * device/include/z180.h,

6536 via literal number. The symbol is placed in the corresponding
6537 position of the data ram
6538 * (pic16_dump_section): relocatable and absolute uninitialized
6539 data are now emitted in sorted order to reduce section naming,
6540 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6541 weren't marked as being in the access bank,
6543 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6545 Added portion of GNU PIC Library under the directory
6546 device/include/pic16 and device/lib/pic16. These files
6547 contain the declarations of SFRs for the PIC18Fxx2 devices.
6548 The directory is initialized via configure from toplevel.
6550 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6552 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6559 2004-01-12 Borut Razem <borut.razem AT siol.net>
6561 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
6562 doc/sdccman.lyx: upper case pragmas are deprecated
6564 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

6577 * doc/sdccman.lyx: Moved and added some sections, small changes
6578 all over. Telling LaTeX to be less strict with word spacing
6579 to better keep the right margin. Changed some notes about
6580 maintainance of the ports in section 3.2.1 - is it OK like this?
6582 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6584 SDCC source changes:
6585 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6591 processor registers declared internally by the port are emitted in
6592 the translation as equates,
6593 * src/pic16/gen.c: inline code is passed unprocessed to the

6619 UPPER for immediate operands,
6620 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6622 * src/pic16/peeph.def: all peepholes with movff are commented out,
6623 because there is a problem in the pcode peep optimizer,
6624 * src/pic16/ralloc.c: the register allocator can now reuse local

6717 include information about variables allocated to the overlay
6720 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6722 * as/mcs51/lkmain.c: Help about -Y option

6734 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6736 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6737 (default behaviour).
6739 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6741 A python script to validate compiler diagnostic messages. It can be
6742 used to verify that sdcc complains about bad c source code and
6743 gives a good location of the error.
6744 * support/valdiag/Makefile,
6745 * support/valdiag/valdiag.py,
6746 * support/valdiag/tests/*
6748 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6750 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6761 * src/common.h: added ifndef/define/endif macros
6762 around the header file.
6763 Bug reported from Jesus Calvino-Fraga
6765 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6767 * sdcc.spec: updated
6768 * device/include/Makefile.in: don't install CVS directories
6769 * device/lib/Makefile.in: added removal of CVS directories after install
6770 * doc/Makefile: fixed install, added local_icons
6771 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6772 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6773 * src/ds390/gen.c (genRightShift): fixed bug #870788
6774 * src/SDCCast.c (decorateType): fixed bug #870781
6776 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6778 PIC16 port related changes:
6779 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6780 added variable stackPos,
6782 * gen.c: genCall, assignResultValue: added support for
6783 pushing/retrieving function parameters to/from stack,
6784 genFunction,genEndFunction: setup stack frame for the
6786 genAddrOf: will be changed according to bug 863624
6788 * added files genutils.c and genutils.h which contain gen*
6789 debugged and optimised functions extracted from gen.c
6791 * glue.c: added variable 'externs' which holds extern symbols,
6792 pic16emitRegularMap: is modified to properly handle relocatable
6793 symbols under the new scheme,
6794 pic16createInterruptVect: is modified
6795 pic16printPublics: is modified to emit 'global' assembler directives,
6796 added pic16_printExterns to print extern symbols,
6797 pic16glue: initializes stack/frame pointer in the beginning of
6798 the assembly output. Temporary hack, will be corrected later,
6799 because gplink yet does not support stack and SDCC does not
6800 yet support a type of crt0.o object to create the final binary.
6802 * Removed many lines that contain 8051 legacy code.
6803 * The code is finally placed under a 'code' directive.
6804 * Added port specific options.
6806 * _process_pragma: simplified since now we do not need *special*
6807 include file to define SFR registers. But a separate header
6808 will be needed. This will be developed later.
6809 * _pic16_parseOptions: added, parses port specific options:
6810 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6811 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6812 --preplace-udata-with=
6814 * _pic16_setDefaultOptions: modified to initialize section names,
6815 but hack is temporarly out of order since it needs improvement.
6816 * _pic16_genAssemblerPreamble: configuration words are emitted by
6817 their address instead of their name. This part is incomplete and
6818 supports only the 18Fxx2 devices. Other devices will emit an error
6819 during assembly since they do not contain the same set of config
6821 * _pic16_genIVT: is modified,
6823 * pcode.c: added definitions for some hardware registers that are needed
6825 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6826 All PCI entries are updated. Now LFSR is supported.
6827 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6828 * added pic16_newpCodeOpLit2 to support instructions with
6829 two literal arguments
6830 * pic16_pCode2str: corrected code that emits assembler instructions
6831 with two literal operands and those that have an access bit modifier
6832 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6833 this fixes a bug which caused some labels to be lost, when an
6834 assembler directive was added, i.e. banksel,
6835 * pic16_FixRegisterBanking: improved logic that causes the insertion
6837 * InlineFunction: functions that are called once, are not any more
6838 inlined. This can be a port option in the future,
6840 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6842 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6843 hold the corresponding uninitialized symbols,
6844 * pic16_allocProcessorRegister: registers have explicit marked the
6846 * pic16_allocInternalRegister: registers are explicit marked as
6848 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6849 processing list, so bit registers were lost,
6852 * ralloc.h: added field 'accessBank' and original symbol operand
6853 in register definition,
6854 * removed the field isMapped from register definition,
6856 ** Several functions have been removed from various sources:
6857 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6858 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6859 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6860 pic16_assignRelocatableRegisters
6862 ** others have been introduced:
6863 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6864 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6866 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6868 * support/scripts/inc2h.pl: changed definition of BIT_AT
6869 to emit 'sbit at' instead of 'bit at'. This was a request.
6871 PIC16 port related preliminary changes:
6872 * gen.c: prefixed function popRegFromString with
6873 pic16_ and all references to it corrected
6874 * pcode.c: all pic16_pc_* hardware registers prefixed
6875 with underscore (_),
6876 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6877 * ralloc.c: newReg(): when register is REG_SFR then
6878 set address to rIdx,
6879 pic16_allocProcessorRegister(): marks register wasUsed=0
6880 pic16_writeUsedRegs(): added a call to assign processor
6881 registers via pic16_assignFixedRegisters
6883 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6885 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6886 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6887 variables in unused register banks. Also the SSEG is placed
6888 wherever there is enough space for it, and IDATA can be anywhere
6889 in internal RAM. For now compile using -Wl-Y[stack_size].
6890 The mem file is different for this option as well, since it
6891 makes no sense of talking about DSEG lenght.
6893 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6895 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6896 in certain cases, e.g. when ROM assignment, patch provided
6897 from Albert den Haan.
6899 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7042 * src/mcs51/peephole.def,
7043 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7922 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7923 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7924 type for bits was changed. It resulted in bit variables becoming

7942 A few small changes that speed up the peephole optimizer.
7946 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7948 Try to make the peephole optimizer smarter by maintaining
7949 an association between the assembly source code and the
7950 iCodes that originated them. Put this information to use
7951 with a new peephole rule condition "notVolatile" so that
7952 the rules can be aggressive yet still safe.
7957 * src/mcs51/peeph.def
7959 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7963 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7964 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7965 if the left or right operand symbols have the accuse flag set.
7967 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7969 Changed the type of the result of the ! (NOT) operator to char;
7970 previously it returned the same type as the source. This allows
7971 us to eliminate all the genFloatNot functions (all of its target
7972 implementations were very buggy) since !float can use the same
7975 * src/SDCCicode.c (ast2iCode): ! returns char

7984 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7985 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7986 during interrupts. Ensure WSAVE is located at a shared bank address.
7987 2. Fixed page selection in some places
7988 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7989 the registers name strings.
7990 4. Fixed "signed / unsigned compare" compiler warnings.
7991 5. The PIC port manages its own allocation of the general purpose
7992 registers, but makes no attempt to reuse them. As a result when
7993 compiling it soon runs out of general purpose registers. Some
7994 additional code was added to the files pcode.c and device.c to walk
7995 through the function call tree and rename the registers so that they
8005 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8012 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8014 Made bitfield a distinct type from bit so that bitfields
8015 convert as per ANSI C and bits retain their traditional
8016 boolean style behaviour. Implemented bitfield support in
8024 * src/ds390/gen.c: bit v bitfield split
8025 * src/z80/gen.c: New support for bitfields
8026 * support/regression/tests/bitfields.c: reenabled z80,
8029 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8031 Rules 246.x, 247.x relate to bitfields, the others speed up
8032 access to xdata mapped I/O devices.
8034 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8036 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8038 Cleaned up genPackBits and genUnpackBits and added two helper

8048 Fixed bug #748310 (pointer to function type mishandled when the
8049 function name is omitted). Also fixed a SIGSEGV when a function
8050 attribute (reentrant, etc) is used on a non-function or on a
8051 function but misplaced before the parameter list.

8080 Made the constant following the "interrupt" keyword optional. If
8081 omitted, the function will not automatically be given an entry
8082 in the interrupt vector table (similar to #pragma NOIV, but
8083 less syntacticly kludgy). The interrupt number is also now
8084 range checked. Also fixed a bug in the high order bit example
8091 * support/Util/SDCCerr.c
8092 * support/Util/SDCCerr.h
8095 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8105 unsigned, but are signed by default
8106 * src/SDCCval.c (constVal): rearranged
8107 * src/SDCCval.c (valMod): preliminary fix
8108 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8152 * src/SDCCval.c (valDiv, valMod): fixed signdness
8153 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8154 signedness of modulo, left and right shift

8617 the compiler with no port specified on command line, a default
8618 port is selected with the new macro DEFAULT_PORT which is
8619 defined in port.h, in setDefaultOptions() linkOptions is removed
8620 from initialization assignment, since now it is a set,
8621 parseCmdLine uses setParseWithComma for linkOptions, in
8622 linkEdit() linkOptions are accessed with new function indexSet()
8623 which returns the i'th item of a set variable. See SDCCset.c, in
8624 linkEdit() when calling buildCmdLine(), added linkOptions as

9690 2003-01-04 <johan AT balder>
9692 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9694 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9695 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9697 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9698 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9705 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9707 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9708 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9710 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9712 * in \sdcc\as\mcs51\ changed these files in order to create an
9713 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9714 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9715 following files to include the previous two files: aslink.dsp,
9716 Makefile.aslink, Makefile.bcc, and Makefile.in.
9718 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9719 .adb instead of .cdb
9721 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9723 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9724 value from option --iram-size.
9726 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9728 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9731 2002-09-18 <wiml AT hhhh.org>
9733 * SDCClrange.h: exposed setFromRange() and setToRange()
9734 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9735 packRegsForAccUse() (bug 542397)
9736 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9737 multiple times and emitting the fetch operations more than once
9738 added aopGetUsesAcc() function to allow binary operators to
9739 fetch their operands in the correct order; made genMinus() emit
9740 compact code for X = LITERAL - Y
9742 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9743 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9744 sprintf() in line 1267.
9746 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9747 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9750 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9751 Changes to aslink (All the changes are marked with 'JCF'):
9753 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9756 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9757 area BSEG. Also moves, if possible, the DATA area down into the internal
9758 ram so more space is available.
9760 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9763 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9764 not bytes. Function summary() which creates a memory usage summary
9765 file with extension .mem. Reports of overlaping stack and small stack
9766 size. If the space for the stack is less than 16 bytes aslink trows a
9769 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9770 the 8051. Option 'y' for memory summary output file.
9772 Changes to sdcc (All the changes are marked with 'JCF'):
9774 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9776 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9777 overlaying area for it (uses RegBankUsed[4]).
9779 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9780 bank zero as used by default. By default aslink locates the stack
9781 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9782 the creation of the .mem file. Delegates the allocation of data area
9783 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9784 the begining of the stack area to aslink.
9786 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9787 glue() in SDCCglue.c creates an area for it.
9789 2002-09-03 Borut Razem <borut.razem AT siol.net>
9790 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9791 sdcc/src/pic/glue.c:
9792 introduced atexit() handler for teporay files removal in case of
9793 errors, assertions, ...
9795 2002-08-29 Borut Razem <borut.razem AT siol.net>
9796 * sdcc/support/cpp2/auto-host_vc_in.h:
9797 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9798 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9799 Maybe there is a similar problem with BORLANDC? It should be checked!
9801 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9802 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9803 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9804 was not executed, and the compiler (cl) launched a warning:
9805 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9807 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9808 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9810 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9811 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9813 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9814 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9815 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9816 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9817 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9818 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9819 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9820 - added Release configuration in VS projects
9821 - review of compiler an linker options
9822 - VC .exe files are generated in bin_vc directory, not to interfere
9823 with binaries generated from other projects (cygwin, mingw, bcc ...)
9825 * sdcc/src/yacc.dsp: added
9827 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9828 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9829 and insert the version number definitions from .version
9831 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9833 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9834 added - genarate auto-host.h using auto-host_vc_in.h as template
9837 removed from CVS, generated automatically
9839 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9840 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9842 2002-08-11 Borut Razem <borut.razem AT siol.net>
9843 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9845 2002-08-10 Borut Razem <borut.razem AT siol.net>
9846 * src/SDCCmain.c (main):
9847 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9848 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9849 The consequence was that some temporary files were not removed.
9852 unification of code in functions tempfilename() and tempfile():
9853 function tempnam() is defined in Visual Studio 6.0 and .NET
9855 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9857 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9858 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9859 - removed compiler command line option /WX: Treats all warnings as errors
9860 - update a list of source files, included into the project
9862 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9863 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9864 changed project type to Generic Project so that can be correcly converted to VS.NET project
9866 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9868 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9870 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9872 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9873 added return 0 statements after assert() to make compiler happy
9875 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9876 added newline in the def file to keep MSC compiler satisfied
9878 * sdcc/src/z80/gen.c:
9879 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9880 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9881 - solved MSC error in function aopDump()
9883 * sdcc_vc.h: define PREFIX as "\\sdcc"
9885 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9886 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9888 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9889 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9890 - Rewrote the register banking algorithm.
9891 - Added pCode live-range analysis to registers (for now, only non-used and
9892 singly-used registers optimized away)
9894 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9896 * 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.
9898 2002-05-10 Scott Dattalo <scott AT dattalo.com>

9921 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9923 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9925 2002-03-28 Johan Knol <johan AT balder>
9927 * src/SDCCval.c: fixed bug #532436
9929 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9931 Added "char *Processor" field to the port structure.
9934 Added -p option. Allows port dependent processor to be specified.
9937 Initialized the new field char *Processor field to NULL in all ports
9940 Compiler generated registers for interrupt context saving
9941 were not getting allocated.
9943 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9946 Fixed left shift. Will promote the left side of a left shift
9947 if a) left shifting more than size of operand or b) when assigned
9948 to something size > size of left side
9950 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9952 tons of changes. Register allocation has been
9953 rewritten. Added customization for the various PICs. Flow
9954 analysis is restructured. ...
9960 Added. device.c is a PIC port hack to accomodate variations
9963 2002-03-13 Michael Hope <michaelh AT vroom>
9965 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9967 2002-03-04 johanknol <johanknol AT manik>
9969 * /src/SDCCval.c: fixed
9971 const unsigned char arr[][2] = { { 0, 1 } };
9972 t18.c:1: error: Initializer element is not constant
9974 2002-03-04 bela <bela AT manik>
9976 * /device/include/mcs51reg.h:
