161 the left operand is shorter than the result (c* = lit-c* + int),
163 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
166 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
168 * src/.version: increased version number to 2.5.5
169 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
170 linking is done manually in pic16 port's _linkEdit,
171 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
172 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
173 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
174 allocate asmop as AOP_ACC,
175 (aopForRemat): added parameter 'bool result' in function declaration,
176 (pic16_aopGet): return AOP_ACC when accessing WREG,

188 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
189 call to allocReg, not by manually allocating a new one,
190 (pic16_assignRegisters): now before going through the register
191 allocating functions mark all registers as free. This eliminates some
192 side effects resulting from peephole parser done earlier in the backbone
194 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

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

2601 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
2602 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2603 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2604 immedDom() returning wrong block; probably fixes bug #1160833)
2606 2005-03-20 Borut Razem <borut.razem AT siol.net>
2608 * support/scripts/inc2h.pl: WIN32 port
2610 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2612 * device/lib/makefile.in: added abs.c and labs.c
2614 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2616 * device/include/stdint.h: added
2617 * device/lib/abs.c: added
2618 * device/lib/labs.c: added
2619 * device/include/stdlib.h: added abs() and labs() prototypes
2620 * device/lib/libsdcc.lib: added abs and labs
2621 * device/include/float.h,
2622 * device/lib/_fsmul.c,
2623 * device/lib/printf_fast.c,
2624 * device/lib/printf_tiny.c: updated comments
2626 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2628 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2631 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2633 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2634 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2636 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2638 * device/lib/printf_large.c: removed inline assembly for portability and
2639 readability. Use printf_fast if speed or size are more important.
2640 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2641 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2643 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2645 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2646 prevent compiler warning
2648 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2650 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2651 moved to level 0 and declared as static. Also they are explicit
2652 placed in access bank. This was necessery because some times they
2653 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2654 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2655 optimizations. Currently only compare to unsigned char is implemented,
2656 * src/pic16/gen.c: added fReturnIdx array,
2657 * (struct resolvedIfx) is moved to gen.h and made public,
2658 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2659 * (aopForSym): added an optimization to directly store in stack of
2660 the operand of a SEND iCode,
2661 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2662 but as registers instead (AOP_REG) using the fReturnIdx array,
2663 * (pic16_freeAsmop): remove the freed register from the
2664 _G.sregsAlloc field,
2665 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2666 a compare of 'WREG',
2667 * (pic16_popGetTempRegCond): changed function prototype, now
2668 function takes also a bitVector argument v which holds the current
2669 set of registers that are allocated for stack access by aopForSym,
2670 registers allocated in aopForSym for accessing stack symbols are not
2671 any more part of the functions usedRegs field,
2672 * (genCall): some times aopOp is called for a stack variable to be
2673 send, aopForSym might perform the push, if this is true make sure
2674 that genCall doesn't push the variable twice by testing _G.resDirect,
2675 * (genFunction): changed testing for unspecified interrupt number
2676 from 256 to INTNO_UNSPEC,
2677 * modified selection scheme of frame pointer generation. Previously
2678 if function did use local registers a frame pointer was generated,
2679 now a frame pointer is generated only if function has arguments
2680 (that need PLUSW2 register access), or has stack arguments, or the
2681 compiler is not instructed to omit the frame pointer,
2682 * (genEndFunction): before restoring local registers that were saved
2683 in the function preamble, also restore the registers that *might*
2684 have been allocated for stack access,
2685 * (genRet): removed some old comments,
2686 * (genCmp, the active (RN's) version): added a call to the
2687 pic16_genCmp_special function to perform the compare with a more
2688 robust and optimized way,
2689 * (genInline): a feature has been added in inline code generation,
2690 which allows a wildcard variable substitution when writing inline
2691 assembly. Code is incomplete and experimental therefore undocumented,
2692 * (genCast): changed order of aopOp for result and right to allow
2693 aopForSym to directly load the result if possible,
2694 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2695 perform an optimized compare on some selected special occasions,
2696 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2697 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2698 generate an IVT any more,
2699 * src/pic16/main.c (pic16_optionsTable): added command line option
2701 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2702 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2704 * src/pic16/NOTES: Raphael Neider added in list of active developers
2705 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2706 jumptable_end to prevent bug #,
2707 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2708 inCond and outCond fields,
2709 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2710 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2711 turn off register spilling,
2712 * (packRegsForOneUse): synced with other ports' versions although it
2713 is not used currently,
2714 * (pic16_packRegisters): added an optimization while reading
2715 structure bitfields, some registers may be saved (malloc code is
2716 decreased by 80 bytes)
2718 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2720 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2721 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2722 this can be optimized more?
2724 2005-03-10 Raphael Neider <rneider AT web.de>
2726 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2727 genNearPointerGet): (hopefully) fixed access to bitfields via
2728 pointers (p->bitN = x; and x = p->bitN; failed)
2730 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2918 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2919 this might fix SIGSEGVs on MinGW...

3007 * (genUminus): rewritten to for efficiency
3008 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
3009 used uninitialized in some cases)

3011 copy the third byte from the int -- now assumes 0x80 (data memory)
3012 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
3013 operands (genAddLit expects the iCode's operands to swapped as
3014 well), fixed leftover bytes (crashed for short left operands)

3363 generated for switch statements. For now you need to set the
3364 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3365 Now 4 algorithms for mcs51 jumptable generation are used:
3366 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3400 * added libc directory. The current version of LibC contains string
3401 functions, ctype functions and macros and some functions of the
3402 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3403 be extensively tested in the future. Standard disclaimer here.
3404 Library is not automatically build yet. But one can build it by

3416 * (pic16_storeForReturn): optimized return of 0,
3417 * (genCmp): experimental code for new genCmp which uses PIC18's
3418 special compare&skip instructions. Initial tests fail some times
3419 with variables grater than 1 byte in size, so new code is disabled,
3420 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3422 * (genCast): began a fix to optimize the casting of a bit to another
3423 bit, now assigning a bitfield to another bitfield will fail, sorry,

3432 and 1 for banking instruction,
3433 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3434 caused stop processing pCodes after a inline assembly block,
3435 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3437 registers when it shouldn't,
3438 * src/pic16/ralloc.c (allocReg): add preliminary support for
3439 supporting a limited set of temporary registers,
3441 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3443 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3444 genDataPointerSet): ensure assignments always copy in MSB to LSB
3446 (loadRegFromAop): recognize CLRH optimization,
3447 (genFunction): optimize RECEIVE iCodes in reentrant functions
3449 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6446 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6448 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6449 loaded with the linker search paths (-L arguments) and the libraries
6450 to be linked with the current source (-l arguments). Changes
6451 currently will affect only the pic16 port.
6452 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6453 include path the port specific paths and port specific libraries,
6454 * gplink command now contains the $3 argument,
6455 * src/pic16/device.h,
6456 * src/pic16/device.c,: structure PIC_device is made public and
6457 renamed to PIC16_device, the same for variable Pics which is renamed

6472 Documenting changes from previous commits.
6473 * configure.in (version 1.56),
6474 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6475 when generating output files to configure the pic16 library,
6476 but now I've commented it out, since gputils aren't installed in the
6477 SF compile farm, so library won't compile
6479 * device/lib/Makefile.in (version 1.56): initially I've added in
6480 target 'all' the prerequestive 'model-pic16' so it compiled the
6481 pic16 library, but now I've commented it out for the same reasons
6483 * added targets 'model-pic16' and 'objects-pic16' to compile the
6485 * added target 'port-specific-objects-pic16' to handle the
6486 generated libraries and copy them into the build/ directory
6487 * added target 'clean-intermediate-pic16' to clean intermediate
6488 files into pic16 directory
6489 * in target 'installdirs' added line to create directory pic16 in
6490 the installation path
6492 * device/include/Makefile.in (version 1.11): in target 'install'
6493 added lines to copy all header files to installation path,
6494 * in target 'installdirs' added line create directory for pic16
6495 headers in the installation path

6510 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6511 option so that it actually works. Made it specific to the z80, since
6512 the gbz80 doesn't have these kinds of I/O ports.
6514 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6516 * device/include/z180.h,

6540 via literal number. The symbol is placed in the corresponding
6541 position of the data ram
6542 * (pic16_dump_section): relocatable and absolute uninitialized
6543 data are now emitted in sorted order to reduce section naming,
6544 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6545 weren't marked as being in the access bank,
6547 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6549 Added portion of GNU PIC Library under the directory
6550 device/include/pic16 and device/lib/pic16. These files
6551 contain the declarations of SFRs for the PIC18Fxx2 devices.
6552 The directory is initialized via configure from toplevel.

6579 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6581 * doc/sdccman.lyx: Moved and added some sections, small changes
6582 all over. Telling LaTeX to be less strict with word spacing
6583 to better keep the right margin. Changed some notes about
6584 maintainance of the ports in section 3.2.1 - is it OK like this?
6586 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6588 SDCC source changes:
6589 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6738 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6740 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6741 (default behaviour).
6743 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6745 A python script to validate compiler diagnostic messages. It can be
6746 used to verify that sdcc complains about bad c source code and
6747 gives a good location of the error.
6748 * support/valdiag/Makefile,
6749 * support/valdiag/valdiag.py,
6750 * support/valdiag/tests/*
6752 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6765 * src/common.h: added ifndef/define/endif macros
6766 around the header file.
6767 Bug reported from Jesus Calvino-Fraga
6769 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6771 * sdcc.spec: updated
6772 * device/include/Makefile.in: don't install CVS directories
6773 * device/lib/Makefile.in: added removal of CVS directories after install
6774 * doc/Makefile: fixed install, added local_icons
6775 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6776 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6777 * src/ds390/gen.c (genRightShift): fixed bug #870788
6778 * src/SDCCast.c (decorateType): fixed bug #870781
6780 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6782 PIC16 port related changes:
6783 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6784 added variable stackPos,
6786 * gen.c: genCall, assignResultValue: added support for
6787 pushing/retrieving function parameters to/from stack,
6788 genFunction,genEndFunction: setup stack frame for the
6790 genAddrOf: will be changed according to bug 863624
6792 * added files genutils.c and genutils.h which contain gen*
6793 debugged and optimised functions extracted from gen.c
6795 * glue.c: added variable 'externs' which holds extern symbols,
6796 pic16emitRegularMap: is modified to properly handle relocatable
6797 symbols under the new scheme,
6798 pic16createInterruptVect: is modified
6799 pic16printPublics: is modified to emit 'global' assembler directives,
6800 added pic16_printExterns to print extern symbols,
6801 pic16glue: initializes stack/frame pointer in the beginning of
6802 the assembly output. Temporary hack, will be corrected later,
6803 because gplink yet does not support stack and SDCC does not
6804 yet support a type of crt0.o object to create the final binary.
6806 * Removed many lines that contain 8051 legacy code.
6807 * The code is finally placed under a 'code' directive.
6808 * Added port specific options.
6810 * _process_pragma: simplified since now we do not need *special*
6811 include file to define SFR registers. But a separate header
6812 will be needed. This will be developed later.
6813 * _pic16_parseOptions: added, parses port specific options:
6814 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6815 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6816 --preplace-udata-with=
6818 * _pic16_setDefaultOptions: modified to initialize section names,
6819 but hack is temporarly out of order since it needs improvement.
6820 * _pic16_genAssemblerPreamble: configuration words are emitted by
6821 their address instead of their name. This part is incomplete and
6822 supports only the 18Fxx2 devices. Other devices will emit an error
6823 during assembly since they do not contain the same set of config
6825 * _pic16_genIVT: is modified,
6827 * pcode.c: added definitions for some hardware registers that are needed
6829 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6830 All PCI entries are updated. Now LFSR is supported.
6831 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6832 * added pic16_newpCodeOpLit2 to support instructions with
6833 two literal arguments
6834 * pic16_pCode2str: corrected code that emits assembler instructions
6835 with two literal operands and those that have an access bit modifier
6836 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6837 this fixes a bug which caused some labels to be lost, when an
6838 assembler directive was added, i.e. banksel,
6839 * pic16_FixRegisterBanking: improved logic that causes the insertion
6841 * InlineFunction: functions that are called once, are not any more
6842 inlined. This can be a port option in the future,
6844 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6846 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6847 hold the corresponding uninitialized symbols,
6848 * pic16_allocProcessorRegister: registers have explicit marked the
6850 * pic16_allocInternalRegister: registers are explicit marked as
6852 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6853 processing list, so bit registers were lost,
6856 * ralloc.h: added field 'accessBank' and original symbol operand
6857 in register definition,
6858 * removed the field isMapped from register definition,
6860 ** Several functions have been removed from various sources:
6861 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6862 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6863 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6864 pic16_assignRelocatableRegisters
6866 ** others have been introduced:
6867 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6868 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6870 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6872 * support/scripts/inc2h.pl: changed definition of BIT_AT
6873 to emit 'sbit at' instead of 'bit at'. This was a request.
6875 PIC16 port related preliminary changes:
6876 * gen.c: prefixed function popRegFromString with
6877 pic16_ and all references to it corrected
6878 * pcode.c: all pic16_pc_* hardware registers prefixed
6879 with underscore (_),
6880 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6881 * ralloc.c: newReg(): when register is REG_SFR then
6882 set address to rIdx,
6883 pic16_allocProcessorRegister(): marks register wasUsed=0
6884 pic16_writeUsedRegs(): added a call to assign processor
6885 registers via pic16_assignFixedRegisters
6887 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6889 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6890 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6891 variables in unused register banks. Also the SSEG is placed
6892 wherever there is enough space for it, and IDATA can be anywhere
6893 in internal RAM. For now compile using -Wl-Y[stack_size].
6894 The mem file is different for this option as well, since it
6895 makes no sense of talking about DSEG lenght.
6897 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6899 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6900 in certain cases, e.g. when ROM assignment, patch provided
6901 from Albert den Haan.
6903 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7046 * src/mcs51/peephole.def,
7047 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7048 (allows non-interrupt and interrupt code to safely compete for a resource

7926 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7927 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7928 type for bits was changed. It resulted in bit variables becoming
7929 global, which is not permitted in PIC 14 assembly output.

7946 A few small changes that speed up the peephole optimizer.
7950 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7952 Try to make the peephole optimizer smarter by maintaining
7953 an association between the assembly source code and the
7954 iCodes that originated them. Put this information to use
7955 with a new peephole rule condition "notVolatile" so that
7956 the rules can be aggressive yet still safe.
7961 * src/mcs51/peeph.def
7963 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7967 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7968 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7969 if the left or right operand symbols have the accuse flag set.
7971 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7973 Changed the type of the result of the ! (NOT) operator to char;
7974 previously it returned the same type as the source. This allows
7975 us to eliminate all the genFloatNot functions (all of its target
7976 implementations were very buggy) since !float can use the same
7979 * src/SDCCicode.c (ast2iCode): ! returns char

7988 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7989 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7990 during interrupts. Ensure WSAVE is located at a shared bank address.
7991 2. Fixed page selection in some places
7992 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7993 the registers name strings.
7994 4. Fixed "signed / unsigned compare" compiler warnings.
7995 5. The PIC port manages its own allocation of the general purpose
7996 registers, but makes no attempt to reuse them. As a result when
7997 compiling it soon runs out of general purpose registers. Some
7998 additional code was added to the files pcode.c and device.c to walk
7999 through the function call tree and rename the registers so that they
8009 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8016 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8018 Made bitfield a distinct type from bit so that bitfields
8019 convert as per ANSI C and bits retain their traditional
8020 boolean style behaviour. Implemented bitfield support in
8028 * src/ds390/gen.c: bit v bitfield split
8029 * src/z80/gen.c: New support for bitfields
8030 * support/regression/tests/bitfields.c: reenabled z80,
8033 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8035 Rules 246.x, 247.x relate to bitfields, the others speed up
8036 access to xdata mapped I/O devices.
8038 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8040 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8042 Cleaned up genPackBits and genUnpackBits and added two helper

8052 Fixed bug #748310 (pointer to function type mishandled when the
8053 function name is omitted). Also fixed a SIGSEGV when a function
8054 attribute (reentrant, etc) is used on a non-function or on a
8055 function but misplaced before the parameter list.

8082 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8084 Made the constant following the "interrupt" keyword optional. If
8085 omitted, the function will not automatically be given an entry
8086 in the interrupt vector table (similar to #pragma NOIV, but
8087 less syntacticly kludgy). The interrupt number is also now
8088 range checked. Also fixed a bug in the high order bit example
8095 * support/Util/SDCCerr.c
8096 * support/Util/SDCCerr.h

8620 support for the PIc16 port in the ports table, when executing
8621 the compiler with no port specified on command line, a default
8622 port is selected with the new macro DEFAULT_PORT which is
8623 defined in port.h, in setDefaultOptions() linkOptions is removed
8624 from initialization assignment, since now it is a set,
8625 parseCmdLine uses setParseWithComma for linkOptions, in
8626 linkEdit() linkOptions are accessed with new function indexSet()
8627 which returns the i'th item of a set variable. See SDCCset.c, in
8628 linkEdit() when calling buildCmdLine(), added linkOptions as
8629 last argument. Now users can pass arguments to gplink via the
8630 -Wl option, main() uses pic16glue() to glue up pic16 programs

9694 2003-01-04 <johan AT balder>
9696 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9698 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9699 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9701 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9702 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9709 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9711 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9712 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9714 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9716 * in \sdcc\as\mcs51\ changed these files in order to create an
9717 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9718 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9719 following files to include the previous two files: aslink.dsp,
9720 Makefile.aslink, Makefile.bcc, and Makefile.in.
9722 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9723 .adb instead of .cdb
9725 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9727 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9728 value from option --iram-size.
9730 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9732 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9735 2002-09-18 <wiml AT hhhh.org>
9737 * SDCClrange.h: exposed setFromRange() and setToRange()
9738 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9739 packRegsForAccUse() (bug 542397)
9740 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9741 multiple times and emitting the fetch operations more than once
9742 added aopGetUsesAcc() function to allow binary operators to
9743 fetch their operands in the correct order; made genMinus() emit
9744 compact code for X = LITERAL - Y
9746 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9747 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9748 sprintf() in line 1267.
9750 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9751 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9754 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9755 Changes to aslink (All the changes are marked with 'JCF'):
9757 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9760 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9761 area BSEG. Also moves, if possible, the DATA area down into the internal
9762 ram so more space is available.
9764 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9767 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9768 not bytes. Function summary() which creates a memory usage summary
9769 file with extension .mem. Reports of overlaping stack and small stack
9770 size. If the space for the stack is less than 16 bytes aslink trows a
9773 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9774 the 8051. Option 'y' for memory summary output file.
9776 Changes to sdcc (All the changes are marked with 'JCF'):
9778 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9780 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9781 overlaying area for it (uses RegBankUsed[4]).
9783 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9784 bank zero as used by default. By default aslink locates the stack
9785 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9786 the creation of the .mem file. Delegates the allocation of data area
9787 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9788 the begining of the stack area to aslink.
9790 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9791 glue() in SDCCglue.c creates an area for it.
9793 2002-09-03 Borut Razem <borut.razem AT siol.net>
9794 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9795 sdcc/src/pic/glue.c:
9796 introduced atexit() handler for teporay files removal in case of
9797 errors, assertions, ...
9799 2002-08-29 Borut Razem <borut.razem AT siol.net>
9800 * sdcc/support/cpp2/auto-host_vc_in.h:
9801 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9802 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9803 Maybe there is a similar problem with BORLANDC? It should be checked!
9805 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9806 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9807 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9808 was not executed, and the compiler (cl) launched a warning:
9809 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9811 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9812 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9814 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9815 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9817 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9818 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9819 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9820 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9821 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9822 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9823 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9824 - added Release configuration in VS projects
9825 - review of compiler an linker options
9826 - VC .exe files are generated in bin_vc directory, not to interfere
9827 with binaries generated from other projects (cygwin, mingw, bcc ...)
9829 * sdcc/src/yacc.dsp: added
9831 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9832 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9833 and insert the version number definitions from .version
9835 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9837 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9838 added - genarate auto-host.h using auto-host_vc_in.h as template
9841 removed from CVS, generated automatically
9843 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9844 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9846 2002-08-11 Borut Razem <borut.razem AT siol.net>
9847 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9849 2002-08-10 Borut Razem <borut.razem AT siol.net>
9850 * src/SDCCmain.c (main):
9851 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9852 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9853 The consequence was that some temporary files were not removed.
9856 unification of code in functions tempfilename() and tempfile():
9857 function tempnam() is defined in Visual Studio 6.0 and .NET
9859 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9861 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9862 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9863 - removed compiler command line option /WX: Treats all warnings as errors
9864 - update a list of source files, included into the project
9866 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9867 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9868 changed project type to Generic Project so that can be correcly converted to VS.NET project
9870 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9872 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9874 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9876 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9877 added return 0 statements after assert() to make compiler happy
9879 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9880 added newline in the def file to keep MSC compiler satisfied
9882 * sdcc/src/z80/gen.c:
9883 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9884 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9885 - solved MSC error in function aopDump()
9887 * sdcc_vc.h: define PREFIX as "\\sdcc"
9889 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9890 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9892 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9893 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9894 - Rewrote the register banking algorithm.
9895 - Added pCode live-range analysis to registers (for now, only non-used and
9896 singly-used registers optimized away)
9898 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9900 * 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.
9902 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9903 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9905 2002-04-22 Michael Hope <michaelh AT vroom>

9921 * src/z80/peeph.def: Added transpose redundent load rule.
9923 * src/z80/main.c: Added force callee saves for jaune.
9925 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9927 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9929 2002-03-28 Johan Knol <johan AT balder>
9931 * src/SDCCval.c: fixed bug #532436
9933 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9935 Added "char *Processor" field to the port structure.
9938 Added -p option. Allows port dependent processor to be specified.
9941 Initialized the new field char *Processor field to NULL in all ports
9944 Compiler generated registers for interrupt context saving
9945 were not getting allocated.
9947 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9950 Fixed left shift. Will promote the left side of a left shift
9951 if a) left shifting more than size of operand or b) when assigned
9952 to something size > size of left side
9954 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9956 tons of changes. Register allocation has been
9957 rewritten. Added customization for the various PICs. Flow
9958 analysis is restructured. ...
9964 Added. device.c is a PIC port hack to accomodate variations
9967 2002-03-13 Michael Hope <michaelh AT vroom>
9969 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9971 2002-03-04 johanknol <johanknol AT manik>
9973 * /src/SDCCval.c: fixed
9975 const unsigned char arr[][2] = { { 0, 1 } };
