148 the left operand is shorter than the result (c* = lit-c* + int),
150 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
153 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
155 * src/.version: increased version number to 2.5.5
156 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
157 linking is done manually in pic16 port's _linkEdit,
158 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
159 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

161 allocate asmop as AOP_ACC,
162 (aopForRemat): added parameter 'bool result' in function declaration,
163 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

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

2582 * src/SDCCdflow.c (computeDataFlow),
2584 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
2586 * src/SDCCcflow.c (*),
2588 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
2589 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2590 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2591 immedDom() returning wrong block; probably fixes bug #1160833)
2593 2005-03-20 Borut Razem <borut.razem AT siol.net>
2595 * support/scripts/inc2h.pl: WIN32 port
2597 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2599 * device/lib/makefile.in: added abs.c and labs.c
2601 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2603 * device/include/stdint.h: added
2604 * device/lib/abs.c: added
2605 * device/lib/labs.c: added
2606 * device/include/stdlib.h: added abs() and labs() prototypes
2607 * device/lib/libsdcc.lib: added abs and labs
2608 * device/include/float.h,
2609 * device/lib/_fsmul.c,
2610 * device/lib/printf_fast.c,
2611 * device/lib/printf_tiny.c: updated comments
2613 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2615 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2618 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2620 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2621 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2623 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2625 * device/lib/printf_large.c: removed inline assembly for portability and
2626 readability. Use printf_fast if speed or size are more important.
2627 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2628 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2630 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2632 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2633 prevent compiler warning
2635 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2637 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2638 moved to level 0 and declared as static. Also they are explicit
2639 placed in access bank. This was necessery because some times they
2640 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2641 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2642 optimizations. Currently only compare to unsigned char is implemented,
2643 * src/pic16/gen.c: added fReturnIdx array,
2644 * (struct resolvedIfx) is moved to gen.h and made public,
2645 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2646 * (aopForSym): added an optimization to directly store in stack of
2647 the operand of a SEND iCode,
2648 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2649 but as registers instead (AOP_REG) using the fReturnIdx array,
2650 * (pic16_freeAsmop): remove the freed register from the
2651 _G.sregsAlloc field,
2652 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2653 a compare of 'WREG',
2654 * (pic16_popGetTempRegCond): changed function prototype, now
2655 function takes also a bitVector argument v which holds the current
2656 set of registers that are allocated for stack access by aopForSym,
2657 registers allocated in aopForSym for accessing stack symbols are not
2658 any more part of the functions usedRegs field,
2659 * (genCall): some times aopOp is called for a stack variable to be
2660 send, aopForSym might perform the push, if this is true make sure
2661 that genCall doesn't push the variable twice by testing _G.resDirect,
2662 * (genFunction): changed testing for unspecified interrupt number
2663 from 256 to INTNO_UNSPEC,
2664 * modified selection scheme of frame pointer generation. Previously
2665 if function did use local registers a frame pointer was generated,
2666 now a frame pointer is generated only if function has arguments
2667 (that need PLUSW2 register access), or has stack arguments, or the
2668 compiler is not instructed to omit the frame pointer,
2669 * (genEndFunction): before restoring local registers that were saved
2670 in the function preamble, also restore the registers that *might*
2671 have been allocated for stack access,
2672 * (genRet): removed some old comments,
2673 * (genCmp, the active (RN's) version): added a call to the
2674 pic16_genCmp_special function to perform the compare with a more
2675 robust and optimized way,
2676 * (genInline): a feature has been added in inline code generation,
2677 which allows a wildcard variable substitution when writing inline
2678 assembly. Code is incomplete and experimental therefore undocumented,
2679 * (genCast): changed order of aopOp for result and right to allow
2680 aopForSym to directly load the result if possible,
2681 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2682 perform an optimized compare on some selected special occasions,
2683 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2684 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2685 generate an IVT any more,
2686 * src/pic16/main.c (pic16_optionsTable): added command line option
2688 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2689 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2691 * src/pic16/NOTES: Raphael Neider added in list of active developers
2692 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2693 jumptable_end to prevent bug #,
2694 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2695 inCond and outCond fields,
2696 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2697 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2698 turn off register spilling,
2699 * (packRegsForOneUse): synced with other ports' versions although it
2700 is not used currently,
2701 * (pic16_packRegisters): added an optimization while reading
2702 structure bitfields, some registers may be saved (malloc code is
2703 decreased by 80 bytes)
2705 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2707 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2708 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2709 this can be optimized more?
2711 2005-03-10 Raphael Neider <rneider AT web.de>
2713 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2714 genNearPointerGet): (hopefully) fixed access to bitfields via
2715 pointers (p->bitN = x; and x = p->bitN; failed)
2717 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3350 generated for switch statements. For now you need to set the
3351 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3352 Now 4 algorithms for mcs51 jumptable generation are used:
3353 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3387 * added libc directory. The current version of LibC contains string
3388 functions, ctype functions and macros and some functions of the
3389 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3390 be extensively tested in the future. Standard disclaimer here.
3391 Library is not automatically build yet. But one can build it by

3403 * (pic16_storeForReturn): optimized return of 0,
3404 * (genCmp): experimental code for new genCmp which uses PIC18's
3405 special compare&skip instructions. Initial tests fail some times
3406 with variables grater than 1 byte in size, so new code is disabled,
3407 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3409 * (genCast): began a fix to optimize the casting of a bit to another
3410 bit, now assigning a bitfield to another bitfield will fail, sorry,

3419 and 1 for banking instruction,
3420 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3421 caused stop processing pCodes after a inline assembly block,

3424 registers when it shouldn't,
3425 * src/pic16/ralloc.c (allocReg): add preliminary support for
3426 supporting a limited set of temporary registers,
3428 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3434 (genFunction): optimize RECEIVE iCodes in reentrant functions
3436 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3447 * device/lib/_gptrget.c (_gptrget),
3448 * device/lib/_gptrgetc.c (_gptrgetc),

6433 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6435 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6436 loaded with the linker search paths (-L arguments) and the libraries
6437 to be linked with the current source (-l arguments). Changes
6438 currently will affect only the pic16 port.
6439 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6440 include path the port specific paths and port specific libraries,
6441 * gplink command now contains the $3 argument,
6442 * src/pic16/device.h,
6443 * src/pic16/device.c,: structure PIC_device is made public and
6444 renamed to PIC16_device, the same for variable Pics which is renamed

6459 Documenting changes from previous commits.
6460 * configure.in (version 1.56),
6461 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6462 when generating output files to configure the pic16 library,
6463 but now I've commented it out, since gputils aren't installed in the
6464 SF compile farm, so library won't compile
6466 * device/lib/Makefile.in (version 1.56): initially I've added in
6467 target 'all' the prerequestive 'model-pic16' so it compiled the
6468 pic16 library, but now I've commented it out for the same reasons
6470 * added targets 'model-pic16' and 'objects-pic16' to compile the
6472 * added target 'port-specific-objects-pic16' to handle the
6473 generated libraries and copy them into the build/ directory
6474 * added target 'clean-intermediate-pic16' to clean intermediate
6475 files into pic16 directory
6476 * in target 'installdirs' added line to create directory pic16 in
6477 the installation path

6480 added lines to copy all header files to installation path,
6481 * in target 'installdirs' added line create directory for pic16
6482 headers in the installation path

6498 option so that it actually works. Made it specific to the z80, since
6499 the gbz80 doesn't have these kinds of I/O ports.
6501 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6503 * device/include/z180.h,

6527 via literal number. The symbol is placed in the corresponding
6528 position of the data ram
6529 * (pic16_dump_section): relocatable and absolute uninitialized
6530 data are now emitted in sorted order to reduce section naming,
6531 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6532 weren't marked as being in the access bank,
6534 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6536 Added portion of GNU PIC Library under the directory
6537 device/include/pic16 and device/lib/pic16. These files
6538 contain the declarations of SFRs for the PIC18Fxx2 devices.
6539 The directory is initialized via configure from toplevel.

6568 * doc/sdccman.lyx: Moved and added some sections, small changes
6569 all over. Telling LaTeX to be less strict with word spacing
6570 to better keep the right margin. Changed some notes about
6571 maintainance of the ports in section 3.2.1 - is it OK like this?
6573 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6575 SDCC source changes:
6576 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6611 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6613 * src/pic16/peeph.def: all peepholes with movff are commented out,
6614 because there is a problem in the pcode peep optimizer,
6615 * src/pic16/ralloc.c: the register allocator can now reuse local

6708 include information about variables allocated to the overlay
6711 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6713 * as/mcs51/lkmain.c: Help about -Y option

6725 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6727 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6728 (default behaviour).
6730 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6732 A python script to validate compiler diagnostic messages. It can be
6733 used to verify that sdcc complains about bad c source code and
6734 gives a good location of the error.
6735 * support/valdiag/Makefile,
6736 * support/valdiag/valdiag.py,
6737 * support/valdiag/tests/*

6753 around the header file.
6754 Bug reported from Jesus Calvino-Fraga
6756 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6758 * sdcc.spec: updated
6759 * device/include/Makefile.in: don't install CVS directories
6760 * device/lib/Makefile.in: added removal of CVS directories after install
6761 * doc/Makefile: fixed install, added local_icons
6762 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6763 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6764 * src/ds390/gen.c (genRightShift): fixed bug #870788
6765 * src/SDCCast.c (decorateType): fixed bug #870781
6767 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6769 PIC16 port related changes:
6770 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6771 added variable stackPos,
6773 * gen.c: genCall, assignResultValue: added support for
6774 pushing/retrieving function parameters to/from stack,
6775 genFunction,genEndFunction: setup stack frame for the
6777 genAddrOf: will be changed according to bug 863624
6779 * added files genutils.c and genutils.h which contain gen*
6780 debugged and optimised functions extracted from gen.c
6782 * glue.c: added variable 'externs' which holds extern symbols,
6783 pic16emitRegularMap: is modified to properly handle relocatable
6784 symbols under the new scheme,
6785 pic16createInterruptVect: is modified
6786 pic16printPublics: is modified to emit 'global' assembler directives,
6787 added pic16_printExterns to print extern symbols,
6788 pic16glue: initializes stack/frame pointer in the beginning of
6789 the assembly output. Temporary hack, will be corrected later,
6790 because gplink yet does not support stack and SDCC does not
6791 yet support a type of crt0.o object to create the final binary.
6793 * Removed many lines that contain 8051 legacy code.
6794 * The code is finally placed under a 'code' directive.
6795 * Added port specific options.
6797 * _process_pragma: simplified since now we do not need *special*
6798 include file to define SFR registers. But a separate header
6799 will be needed. This will be developed later.
6800 * _pic16_parseOptions: added, parses port specific options:
6801 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6802 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6803 --preplace-udata-with=
6805 * _pic16_setDefaultOptions: modified to initialize section names,
6806 but hack is temporarly out of order since it needs improvement.
6807 * _pic16_genAssemblerPreamble: configuration words are emitted by
6808 their address instead of their name. This part is incomplete and
6809 supports only the 18Fxx2 devices. Other devices will emit an error
6810 during assembly since they do not contain the same set of config
6812 * _pic16_genIVT: is modified,
6814 * pcode.c: added definitions for some hardware registers that are needed
6816 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6817 All PCI entries are updated. Now LFSR is supported.
6818 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6819 * added pic16_newpCodeOpLit2 to support instructions with
6820 two literal arguments
6821 * pic16_pCode2str: corrected code that emits assembler instructions
6822 with two literal operands and those that have an access bit modifier
6823 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6824 this fixes a bug which caused some labels to be lost, when an
6825 assembler directive was added, i.e. banksel,
6826 * pic16_FixRegisterBanking: improved logic that causes the insertion
6828 * InlineFunction: functions that are called once, are not any more
6829 inlined. This can be a port option in the future,
6831 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6833 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6834 hold the corresponding uninitialized symbols,
6835 * pic16_allocProcessorRegister: registers have explicit marked the
6837 * pic16_allocInternalRegister: registers are explicit marked as
6839 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6840 processing list, so bit registers were lost,
6843 * ralloc.h: added field 'accessBank' and original symbol operand
6844 in register definition,
6845 * removed the field isMapped from register definition,
6847 ** Several functions have been removed from various sources:
6848 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6849 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6850 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6851 pic16_assignRelocatableRegisters
6853 ** others have been introduced:
6854 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6855 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6857 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6859 * support/scripts/inc2h.pl: changed definition of BIT_AT
6860 to emit 'sbit at' instead of 'bit at'. This was a request.
6862 PIC16 port related preliminary changes:
6863 * gen.c: prefixed function popRegFromString with
6864 pic16_ and all references to it corrected
6865 * pcode.c: all pic16_pc_* hardware registers prefixed
6866 with underscore (_),
6867 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6868 * ralloc.c: newReg(): when register is REG_SFR then
6869 set address to rIdx,
6870 pic16_allocProcessorRegister(): marks register wasUsed=0
6871 pic16_writeUsedRegs(): added a call to assign processor
6872 registers via pic16_assignFixedRegisters
6874 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6876 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6877 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6878 variables in unused register banks. Also the SSEG is placed
6879 wherever there is enough space for it, and IDATA can be anywhere
6880 in internal RAM. For now compile using -Wl-Y[stack_size].
6881 The mem file is different for this option as well, since it
6882 makes no sense of talking about DSEG lenght.
6884 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6886 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6887 in certain cases, e.g. when ROM assignment, patch provided
6888 from Albert den Haan.
6890 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7033 * src/mcs51/peephole.def,
7034 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7035 (allows non-interrupt and interrupt code to safely compete for a resource

7913 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7914 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7915 type for bits was changed. It resulted in bit variables becoming

7933 A few small changes that speed up the peephole optimizer.
7937 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7939 Try to make the peephole optimizer smarter by maintaining
7940 an association between the assembly source code and the
7941 iCodes that originated them. Put this information to use
7942 with a new peephole rule condition "notVolatile" so that
7943 the rules can be aggressive yet still safe.
7948 * src/mcs51/peeph.def
7950 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7954 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7955 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7956 if the left or right operand symbols have the accuse flag set.
7958 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7960 Changed the type of the result of the ! (NOT) operator to char;
7961 previously it returned the same type as the source. This allows
7962 us to eliminate all the genFloatNot functions (all of its target
7963 implementations were very buggy) since !float can use the same
7966 * src/SDCCicode.c (ast2iCode): ! returns char

7975 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7976 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7977 during interrupts. Ensure WSAVE is located at a shared bank address.
7978 2. Fixed page selection in some places
7979 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7980 the registers name strings.
7981 4. Fixed "signed / unsigned compare" compiler warnings.
7982 5. The PIC port manages its own allocation of the general purpose
7983 registers, but makes no attempt to reuse them. As a result when
7984 compiling it soon runs out of general purpose registers. Some
7985 additional code was added to the files pcode.c and device.c to walk
7986 through the function call tree and rename the registers so that they
7996 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8003 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8005 Made bitfield a distinct type from bit so that bitfields
8006 convert as per ANSI C and bits retain their traditional
8007 boolean style behaviour. Implemented bitfield support in
8015 * src/ds390/gen.c: bit v bitfield split
8016 * src/z80/gen.c: New support for bitfields
8017 * support/regression/tests/bitfields.c: reenabled z80,
8020 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8022 Rules 246.x, 247.x relate to bitfields, the others speed up
8023 access to xdata mapped I/O devices.
8025 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8027 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8029 Cleaned up genPackBits and genUnpackBits and added two helper

8039 Fixed bug #748310 (pointer to function type mishandled when the
8040 function name is omitted). Also fixed a SIGSEGV when a function
8041 attribute (reentrant, etc) is used on a non-function or on a
8042 function but misplaced before the parameter list.

8071 Made the constant following the "interrupt" keyword optional. If
8072 omitted, the function will not automatically be given an entry
8073 in the interrupt vector table (similar to #pragma NOIV, but
8074 less syntacticly kludgy). The interrupt number is also now
8075 range checked. Also fixed a bug in the high order bit example
8082 * support/Util/SDCCerr.c
8083 * support/Util/SDCCerr.h
8086 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8096 unsigned, but are signed by default
8097 * src/SDCCval.c (constVal): rearranged
8098 * src/SDCCval.c (valMod): preliminary fix
8099 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8142 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8143 * src/SDCCval.c (valDiv, valMod): fixed signdness
8144 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8145 signedness of modulo, left and right shift
8146 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

8608 the compiler with no port specified on command line, a default
8609 port is selected with the new macro DEFAULT_PORT which is
8610 defined in port.h, in setDefaultOptions() linkOptions is removed
8611 from initialization assignment, since now it is a set,
8612 parseCmdLine uses setParseWithComma for linkOptions, in
8613 linkEdit() linkOptions are accessed with new function indexSet()
8614 which returns the i'th item of a set variable. See SDCCset.c, in

9681 2003-01-04 <johan AT balder>
9683 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9685 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9686 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9688 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9689 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9698 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9699 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9701 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9703 * in \sdcc\as\mcs51\ changed these files in order to create an
9704 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9705 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9706 following files to include the previous two files: aslink.dsp,
9707 Makefile.aslink, Makefile.bcc, and Makefile.in.
9709 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9710 .adb instead of .cdb
9712 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9714 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9715 value from option --iram-size.
9717 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9719 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9722 2002-09-18 <wiml AT hhhh.org>
9724 * SDCClrange.h: exposed setFromRange() and setToRange()
9725 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9726 packRegsForAccUse() (bug 542397)
9727 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9728 multiple times and emitting the fetch operations more than once
9729 added aopGetUsesAcc() function to allow binary operators to
9730 fetch their operands in the correct order; made genMinus() emit
9731 compact code for X = LITERAL - Y
9733 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9734 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9735 sprintf() in line 1267.
9737 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9738 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9741 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9742 Changes to aslink (All the changes are marked with 'JCF'):
9744 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9747 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9748 area BSEG. Also moves, if possible, the DATA area down into the internal
9749 ram so more space is available.
9751 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9754 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9755 not bytes. Function summary() which creates a memory usage summary
9756 file with extension .mem. Reports of overlaping stack and small stack
9757 size. If the space for the stack is less than 16 bytes aslink trows a
9760 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9761 the 8051. Option 'y' for memory summary output file.
9763 Changes to sdcc (All the changes are marked with 'JCF'):
9765 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9767 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9768 overlaying area for it (uses RegBankUsed[4]).
9770 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9771 bank zero as used by default. By default aslink locates the stack
9772 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9773 the creation of the .mem file. Delegates the allocation of data area
9774 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9775 the begining of the stack area to aslink.
9777 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9778 glue() in SDCCglue.c creates an area for it.
9780 2002-09-03 Borut Razem <borut.razem AT siol.net>
9781 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9782 sdcc/src/pic/glue.c:
9783 introduced atexit() handler for teporay files removal in case of
9784 errors, assertions, ...
9786 2002-08-29 Borut Razem <borut.razem AT siol.net>
9787 * sdcc/support/cpp2/auto-host_vc_in.h:
9788 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9789 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9790 Maybe there is a similar problem with BORLANDC? It should be checked!
9792 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9793 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9794 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9795 was not executed, and the compiler (cl) launched a warning:
9796 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9798 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9799 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9801 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9802 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9804 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9805 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9806 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9807 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9808 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9809 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9810 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9811 - added Release configuration in VS projects
9812 - review of compiler an linker options
9813 - VC .exe files are generated in bin_vc directory, not to interfere
9814 with binaries generated from other projects (cygwin, mingw, bcc ...)
9816 * sdcc/src/yacc.dsp: added
9818 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9819 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9820 and insert the version number definitions from .version
9822 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9824 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9825 added - genarate auto-host.h using auto-host_vc_in.h as template
9828 removed from CVS, generated automatically
9830 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9831 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9833 2002-08-11 Borut Razem <borut.razem AT siol.net>
9834 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9836 2002-08-10 Borut Razem <borut.razem AT siol.net>
9837 * src/SDCCmain.c (main):
9838 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9839 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9840 The consequence was that some temporary files were not removed.
9843 unification of code in functions tempfilename() and tempfile():
9844 function tempnam() is defined in Visual Studio 6.0 and .NET
9846 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9848 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9849 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9850 - removed compiler command line option /WX: Treats all warnings as errors
9851 - update a list of source files, included into the project
9853 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9854 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9855 changed project type to Generic Project so that can be correcly converted to VS.NET project
9857 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9859 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9861 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9863 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9864 added return 0 statements after assert() to make compiler happy
9866 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9867 added newline in the def file to keep MSC compiler satisfied
9869 * sdcc/src/z80/gen.c:
9870 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9871 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9872 - solved MSC error in function aopDump()
9874 * sdcc_vc.h: define PREFIX as "\\sdcc"
9876 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9877 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9879 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9880 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9881 - Rewrote the register banking algorithm.
9882 - Added pCode live-range analysis to registers (for now, only non-used and
9883 singly-used registers optimized away)
9885 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9887 * 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.
9889 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9890 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

9912 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9914 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9916 2002-03-28 Johan Knol <johan AT balder>
9918 * src/SDCCval.c: fixed bug #532436
9920 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9922 Added "char *Processor" field to the port structure.
9925 Added -p option. Allows port dependent processor to be specified.
9928 Initialized the new field char *Processor field to NULL in all ports
9931 Compiler generated registers for interrupt context saving
9932 were not getting allocated.
9934 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9937 Fixed left shift. Will promote the left side of a left shift
9938 if a) left shifting more than size of operand or b) when assigned
9939 to something size > size of left side
9941 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9943 tons of changes. Register allocation has been
9944 rewritten. Added customization for the various PICs. Flow
9945 analysis is restructured. ...
9951 Added. device.c is a PIC port hack to accomodate variations
9954 2002-03-13 Michael Hope <michaelh AT vroom>
9956 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9958 2002-03-04 johanknol <johanknol AT manik>
9960 * /src/SDCCval.c: fixed
9962 const unsigned char arr[][2] = { { 0, 1 } };
9963 t18.c:1: error: Initializer element is not constant
9965 2002-03-04 bela <bela AT manik>
9967 * /device/include/mcs51reg.h:
