180 the left operand is shorter than the result (c* = lit-c* + int),
182 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
185 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
187 * src/.version: increased version number to 2.5.5
188 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
189 linking is done manually in pic16 port's _linkEdit,
190 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
191 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

2574 always available in leading double underscore form. The C99 support is
2575 mostly missing, but it's a start.
2576 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2577 reserved identifier "__data".
2579 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2581 * src/mcs51/peeph.def: fixed bug 1170013

2622 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2623 immedDom() returning wrong block; probably fixes bug #1160833)
2625 2005-03-20 Borut Razem <borut.razem AT siol.net>
2627 * support/scripts/inc2h.pl: WIN32 port
2629 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2631 * device/lib/makefile.in: added abs.c and labs.c
2633 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2635 * device/include/stdint.h: added
2636 * device/lib/abs.c: added
2637 * device/lib/labs.c: added
2638 * device/include/stdlib.h: added abs() and labs() prototypes

2645 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2647 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

2653 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2655 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2657 * device/lib/printf_large.c: removed inline assembly for portability and
2658 readability. Use printf_fast if speed or size are more important.
2659 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2660 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2662 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2664 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2665 prevent compiler warning
2667 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2669 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2670 moved to level 0 and declared as static. Also they are explicit
2671 placed in access bank. This was necessery because some times they
2672 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2673 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2674 optimizations. Currently only compare to unsigned char is implemented,
2675 * src/pic16/gen.c: added fReturnIdx array,
2676 * (struct resolvedIfx) is moved to gen.h and made public,
2677 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2678 * (aopForSym): added an optimization to directly store in stack of
2679 the operand of a SEND iCode,
2680 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2681 but as registers instead (AOP_REG) using the fReturnIdx array,
2682 * (pic16_freeAsmop): remove the freed register from the
2683 _G.sregsAlloc field,
2684 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2685 a compare of 'WREG',
2686 * (pic16_popGetTempRegCond): changed function prototype, now
2687 function takes also a bitVector argument v which holds the current
2688 set of registers that are allocated for stack access by aopForSym,
2689 registers allocated in aopForSym for accessing stack symbols are not
2690 any more part of the functions usedRegs field,
2691 * (genCall): some times aopOp is called for a stack variable to be
2692 send, aopForSym might perform the push, if this is true make sure
2693 that genCall doesn't push the variable twice by testing _G.resDirect,
2694 * (genFunction): changed testing for unspecified interrupt number
2695 from 256 to INTNO_UNSPEC,
2696 * modified selection scheme of frame pointer generation. Previously
2697 if function did use local registers a frame pointer was generated,
2698 now a frame pointer is generated only if function has arguments
2699 (that need PLUSW2 register access), or has stack arguments, or the
2700 compiler is not instructed to omit the frame pointer,
2701 * (genEndFunction): before restoring local registers that were saved
2702 in the function preamble, also restore the registers that *might*
2703 have been allocated for stack access,
2704 * (genRet): removed some old comments,
2705 * (genCmp, the active (RN's) version): added a call to the
2706 pic16_genCmp_special function to perform the compare with a more
2707 robust and optimized way,
2708 * (genInline): a feature has been added in inline code generation,
2709 which allows a wildcard variable substitution when writing inline
2710 assembly. Code is incomplete and experimental therefore undocumented,
2711 * (genCast): changed order of aopOp for result and right to allow
2712 aopForSym to directly load the result if possible,
2713 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2714 perform an optimized compare on some selected special occasions,
2715 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2716 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2717 generate an IVT any more,
2718 * src/pic16/main.c (pic16_optionsTable): added command line option
2720 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2721 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2723 * src/pic16/NOTES: Raphael Neider added in list of active developers
2724 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2725 jumptable_end to prevent bug #,
2726 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2727 inCond and outCond fields,
2728 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2729 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2730 turn off register spilling,
2731 * (packRegsForOneUse): synced with other ports' versions although it
2732 is not used currently,
2733 * (pic16_packRegisters): added an optimization while reading
2734 structure bitfields, some registers may be saved (malloc code is
2735 decreased by 80 bytes)
2737 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2739 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2740 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2741 this can be optimized more?
2743 2005-03-10 Raphael Neider <rneider AT web.de>
2745 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2746 genNearPointerGet): (hopefully) fixed access to bitfields via
2747 pointers (p->bitN = x; and x = p->bitN; failed)
2749 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2937 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2938 this might fix SIGSEGVs on MinGW...
2939 * src/SDCCopt.c (killDeadCode): restored original behaviour
2940 (volatile operands might get thrown away though)
2942 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3381 Adding support for replacing ljmps with sjmps in jumptables
3382 generated for switch statements. For now you need to set the
3383 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3384 Now 4 algorithms for mcs51 jumptable generation are used:
3385 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3386 addresses loaded pc-relative for up to 112 cases and stack-pushing
3387 target addresses loaded with offset from dptr for up to 256 cases.

3414 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3415 to call when a stack overflow occurs,
3416 * (malloc.h): added CVS Id tag,
3417 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3419 * added libc directory. The current version of LibC contains string
3420 functions, ctype functions and macros and some functions of the
3421 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3422 be extensively tested in the future. Standard disclaimer here.
3423 Library is not automatically build yet. But one can build it by
3424 invoking 'make' inside the libc directory.
3425 * added ADC library under libio. Preliminary version yet.
3427 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3431 temporary registers, its a buggy feature and will be removed,
3432 * (pic16_popGet): set register instance field in AOP_CRY,
3433 * (pic16_outBitC): fixed for results in size greater than 1,
3434 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3435 * (pic16_storeForReturn): optimized return of 0,
3436 * (genCmp): experimental code for new genCmp which uses PIC18's
3437 special compare&skip instructions. Initial tests fail some times
3438 with variables grater than 1 byte in size, so new code is disabled,
3439 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3441 * (genCast): began a fix to optimize the casting of a bit to another
3442 bit, now assigning a bitfield to another bitfield will fail, sorry,
3443 * src/pic16/main.c: disabled the use of lr-support feature,
3444 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3447 bits with offset (case PO_GPR_BIT),
3448 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in

6465 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6467 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6468 loaded with the linker search paths (-L arguments) and the libraries
6469 to be linked with the current source (-l arguments). Changes
6470 currently will affect only the pic16 port.
6471 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6472 include path the port specific paths and port specific libraries,
6473 * gplink command now contains the $3 argument,
6474 * src/pic16/device.h,
6475 * src/pic16/device.c,: structure PIC_device is made public and
6476 renamed to PIC16_device, the same for variable Pics which is renamed

6491 Documenting changes from previous commits.
6492 * configure.in (version 1.56),
6493 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6494 when generating output files to configure the pic16 library,
6495 but now I've commented it out, since gputils aren't installed in the
6496 SF compile farm, so library won't compile
6498 * device/lib/Makefile.in (version 1.56): initially I've added in
6499 target 'all' the prerequestive 'model-pic16' so it compiled the
6500 pic16 library, but now I've commented it out for the same reasons
6502 * added targets 'model-pic16' and 'objects-pic16' to compile the
6504 * added target 'port-specific-objects-pic16' to handle the
6505 generated libraries and copy them into the build/ directory
6506 * added target 'clean-intermediate-pic16' to clean intermediate
6507 files into pic16 directory
6508 * in target 'installdirs' added line to create directory pic16 in
6509 the installation path
6511 * device/include/Makefile.in (version 1.11): in target 'install'
6512 added lines to copy all header files to installation path,
6513 * in target 'installdirs' added line create directory for pic16
6514 headers in the installation path

6530 option so that it actually works. Made it specific to the z80, since
6531 the gbz80 doesn't have these kinds of I/O ports.
6533 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6535 * device/include/z180.h,

6564 weren't marked as being in the access bank,
6566 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6568 Added portion of GNU PIC Library under the directory
6569 device/include/pic16 and device/lib/pic16. These files
6570 contain the declarations of SFRs for the PIC18Fxx2 devices.
6571 The directory is initialized via configure from toplevel.
6573 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6601 all over. Telling LaTeX to be less strict with word spacing
6602 to better keep the right margin. Changed some notes about
6603 maintainance of the ports in section 3.2.1 - is it OK like this?
6605 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6643 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6645 * src/pic16/peeph.def: all peepholes with movff are commented out,
6646 because there is a problem in the pcode peep optimizer,
6647 * src/pic16/ralloc.c: the register allocator can now reuse local

6724 2004-01-07 Borut Razem <borut.razem AT siol.net>
6726 * support/scripts/sdcc.nsi: update PATH
6727 * support/scripts/sdcc.ico: craeted

6740 include information about variables allocated to the overlay
6743 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6745 * as/mcs51/lkmain.c: Help about -Y option

6757 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6759 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6760 (default behaviour).
6762 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6764 A python script to validate compiler diagnostic messages. It can be
6765 used to verify that sdcc complains about bad c source code and
6766 gives a good location of the error.
6767 * support/valdiag/Makefile,
6768 * support/valdiag/valdiag.py,
6769 * support/valdiag/tests/*
6771 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6786 Bug reported from Jesus Calvino-Fraga
6788 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6790 * sdcc.spec: updated
6791 * device/include/Makefile.in: don't install CVS directories
6792 * device/lib/Makefile.in: added removal of CVS directories after install
6793 * doc/Makefile: fixed install, added local_icons
6794 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6795 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6796 * src/ds390/gen.c (genRightShift): fixed bug #870788
6797 * src/SDCCast.c (decorateType): fixed bug #870781
6799 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6801 PIC16 port related changes:
6802 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6803 added variable stackPos,
6805 * gen.c: genCall, assignResultValue: added support for
6806 pushing/retrieving function parameters to/from stack,
6807 genFunction,genEndFunction: setup stack frame for the
6809 genAddrOf: will be changed according to bug 863624
6811 * added files genutils.c and genutils.h which contain gen*
6812 debugged and optimised functions extracted from gen.c
6814 * glue.c: added variable 'externs' which holds extern symbols,
6815 pic16emitRegularMap: is modified to properly handle relocatable
6816 symbols under the new scheme,
6817 pic16createInterruptVect: is modified
6818 pic16printPublics: is modified to emit 'global' assembler directives,
6819 added pic16_printExterns to print extern symbols,
6820 pic16glue: initializes stack/frame pointer in the beginning of
6821 the assembly output. Temporary hack, will be corrected later,
6822 because gplink yet does not support stack and SDCC does not
6823 yet support a type of crt0.o object to create the final binary.
6825 * Removed many lines that contain 8051 legacy code.
6826 * The code is finally placed under a 'code' directive.
6827 * Added port specific options.
6829 * _process_pragma: simplified since now we do not need *special*
6830 include file to define SFR registers. But a separate header
6831 will be needed. This will be developed later.
6832 * _pic16_parseOptions: added, parses port specific options:
6833 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6834 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6835 --preplace-udata-with=
6837 * _pic16_setDefaultOptions: modified to initialize section names,
6838 but hack is temporarly out of order since it needs improvement.
6839 * _pic16_genAssemblerPreamble: configuration words are emitted by
6840 their address instead of their name. This part is incomplete and
6841 supports only the 18Fxx2 devices. Other devices will emit an error
6842 during assembly since they do not contain the same set of config
6844 * _pic16_genIVT: is modified,
6846 * pcode.c: added definitions for some hardware registers that are needed
6848 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6849 All PCI entries are updated. Now LFSR is supported.
6850 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6851 * added pic16_newpCodeOpLit2 to support instructions with
6852 two literal arguments
6853 * pic16_pCode2str: corrected code that emits assembler instructions
6854 with two literal operands and those that have an access bit modifier
6855 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6856 this fixes a bug which caused some labels to be lost, when an
6857 assembler directive was added, i.e. banksel,
6858 * pic16_FixRegisterBanking: improved logic that causes the insertion
6860 * InlineFunction: functions that are called once, are not any more
6861 inlined. This can be a port option in the future,
6863 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6865 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6866 hold the corresponding uninitialized symbols,
6867 * pic16_allocProcessorRegister: registers have explicit marked the
6869 * pic16_allocInternalRegister: registers are explicit marked as
6871 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6872 processing list, so bit registers were lost,
6875 * ralloc.h: added field 'accessBank' and original symbol operand
6876 in register definition,
6877 * removed the field isMapped from register definition,
6879 ** Several functions have been removed from various sources:
6880 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6881 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6882 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6883 pic16_assignRelocatableRegisters
6885 ** others have been introduced:
6886 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6887 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6889 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6891 * support/scripts/inc2h.pl: changed definition of BIT_AT
6892 to emit 'sbit at' instead of 'bit at'. This was a request.
6894 PIC16 port related preliminary changes:
6895 * gen.c: prefixed function popRegFromString with
6896 pic16_ and all references to it corrected
6897 * pcode.c: all pic16_pc_* hardware registers prefixed
6898 with underscore (_),
6899 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6900 * ralloc.c: newReg(): when register is REG_SFR then
6901 set address to rIdx,
6902 pic16_allocProcessorRegister(): marks register wasUsed=0
6903 pic16_writeUsedRegs(): added a call to assign processor
6904 registers via pic16_assignFixedRegisters
6906 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6908 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6909 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6910 variables in unused register banks. Also the SSEG is placed
6911 wherever there is enough space for it, and IDATA can be anywhere
6912 in internal RAM. For now compile using -Wl-Y[stack_size].
6913 The mem file is different for this option as well, since it
6914 makes no sense of talking about DSEG lenght.
6916 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6918 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6919 in certain cases, e.g. when ROM assignment, patch provided
6920 from Albert den Haan.
6922 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7068 without the non-interrupt code having to disable interrupts)
7070 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7072 * src/SDCCicode.c (geniCodeAdd),

7945 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7946 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7947 type for bits was changed. It resulted in bit variables becoming

7965 A few small changes that speed up the peephole optimizer.
7969 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7971 Try to make the peephole optimizer smarter by maintaining
7972 an association between the assembly source code and the
7973 iCodes that originated them. Put this information to use
7974 with a new peephole rule condition "notVolatile" so that
7975 the rules can be aggressive yet still safe.
7980 * src/mcs51/peeph.def
7982 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7986 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7987 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7988 if the left or right operand symbols have the accuse flag set.
7990 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7992 Changed the type of the result of the ! (NOT) operator to char;
7993 previously it returned the same type as the source. This allows
7994 us to eliminate all the genFloatNot functions (all of its target
7995 implementations were very buggy) since !float can use the same
7998 * src/SDCCicode.c (ast2iCode): ! returns char

8007 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8008 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8009 during interrupts. Ensure WSAVE is located at a shared bank address.
8010 2. Fixed page selection in some places
8011 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8012 the registers name strings.
8013 4. Fixed "signed / unsigned compare" compiler warnings.
8014 5. The PIC port manages its own allocation of the general purpose
8015 registers, but makes no attempt to reuse them. As a result when
8016 compiling it soon runs out of general purpose registers. Some
8017 additional code was added to the files pcode.c and device.c to walk
8018 through the function call tree and rename the registers so that they
8028 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8029 genPlus() & genMinus() when the result is the same as left or right

8035 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8037 Made bitfield a distinct type from bit so that bitfields
8038 convert as per ANSI C and bits retain their traditional
8039 boolean style behaviour. Implemented bitfield support in
8047 * src/ds390/gen.c: bit v bitfield split
8048 * src/z80/gen.c: New support for bitfields
8049 * support/regression/tests/bitfields.c: reenabled z80,
8052 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8054 Rules 246.x, 247.x relate to bitfields, the others speed up
8055 access to xdata mapped I/O devices.
8057 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8059 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8061 Cleaned up genPackBits and genUnpackBits and added two helper
8062 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8063 for literal assignments in genPackBits (thanks to Frieder for
8069 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8071 Fixed bug #748310 (pointer to function type mishandled when the
8072 function name is omitted). Also fixed a SIGSEGV when a function
8073 attribute (reentrant, etc) is used on a non-function or on a

8104 omitted, the function will not automatically be given an entry
8105 in the interrupt vector table (similar to #pragma NOIV, but

8643 from initialization assignment, since now it is a set,
8644 parseCmdLine uses setParseWithComma for linkOptions, in
8645 linkEdit() linkOptions are accessed with new function indexSet()
8646 which returns the i'th item of a set variable. See SDCCset.c, in
8647 linkEdit() when calling buildCmdLine(), added linkOptions as
8648 last argument. Now users can pass arguments to gplink via the
8649 -Wl option, main() uses pic16glue() to glue up pic16 programs

8663 gpasm complaining and test the linkage with gplink, _linkCmd and
8664 _asmCmd changed to be more gplink and gpasm friendly
8665 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8666 produced an error when parsed, peep rule 12 is added to utilize
8667 movff, but it is commented out since the pCode does not support
8668 yet a command with 2 address arguments

9690 2003-01-07 <johan AT balder>
9692 * src/SDCCast.c (decorateType): fixed bug #600035

9707 * src/SDCCicode.c: fixed array add
9709 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9710 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9711 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9713 2003-01-04 <johan AT balder>
9715 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9717 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9718 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9720 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9721 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9727 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9728 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9730 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9731 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9733 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9735 * in \sdcc\as\mcs51\ changed these files in order to create an
9736 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9737 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9738 following files to include the previous two files: aslink.dsp,
9739 Makefile.aslink, Makefile.bcc, and Makefile.in.
9741 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9742 .adb instead of .cdb
9744 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9746 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9747 value from option --iram-size.
9749 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9751 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9754 2002-09-18 <wiml AT hhhh.org>
9756 * SDCClrange.h: exposed setFromRange() and setToRange()
9757 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9758 packRegsForAccUse() (bug 542397)
9759 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9760 multiple times and emitting the fetch operations more than once
9761 added aopGetUsesAcc() function to allow binary operators to
9762 fetch their operands in the correct order; made genMinus() emit
9763 compact code for X = LITERAL - Y
9765 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9766 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9767 sprintf() in line 1267.
9769 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9770 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9773 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9774 Changes to aslink (All the changes are marked with 'JCF'):
9776 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9779 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9780 area BSEG. Also moves, if possible, the DATA area down into the internal
9781 ram so more space is available.
9783 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9786 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9787 not bytes. Function summary() which creates a memory usage summary
9788 file with extension .mem. Reports of overlaping stack and small stack
9789 size. If the space for the stack is less than 16 bytes aslink trows a
9792 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9793 the 8051. Option 'y' for memory summary output file.
9795 Changes to sdcc (All the changes are marked with 'JCF'):
9797 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9799 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9800 overlaying area for it (uses RegBankUsed[4]).
9802 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9803 bank zero as used by default. By default aslink locates the stack
9804 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9805 the creation of the .mem file. Delegates the allocation of data area
9806 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9807 the begining of the stack area to aslink.
9809 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9810 glue() in SDCCglue.c creates an area for it.
9812 2002-09-03 Borut Razem <borut.razem AT siol.net>
9813 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9814 sdcc/src/pic/glue.c:
9815 introduced atexit() handler for teporay files removal in case of
9816 errors, assertions, ...
9818 2002-08-29 Borut Razem <borut.razem AT siol.net>
9819 * sdcc/support/cpp2/auto-host_vc_in.h:
9820 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9821 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9822 Maybe there is a similar problem with BORLANDC? It should be checked!
9824 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9825 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9826 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9827 was not executed, and the compiler (cl) launched a warning:
9828 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9830 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9831 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9833 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9834 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9836 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9837 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9838 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9839 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9840 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9841 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9842 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9843 - added Release configuration in VS projects
9844 - review of compiler an linker options
9845 - VC .exe files are generated in bin_vc directory, not to interfere
9846 with binaries generated from other projects (cygwin, mingw, bcc ...)
9848 * sdcc/src/yacc.dsp: added
9850 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9851 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9852 and insert the version number definitions from .version
9854 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9856 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9857 added - genarate auto-host.h using auto-host_vc_in.h as template
9860 removed from CVS, generated automatically
9862 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9863 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9865 2002-08-11 Borut Razem <borut.razem AT siol.net>
9866 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9868 2002-08-10 Borut Razem <borut.razem AT siol.net>
9869 * src/SDCCmain.c (main):
9870 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9871 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9872 The consequence was that some temporary files were not removed.
9875 unification of code in functions tempfilename() and tempfile():
9876 function tempnam() is defined in Visual Studio 6.0 and .NET
9878 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9880 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9881 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9882 - removed compiler command line option /WX: Treats all warnings as errors
9883 - update a list of source files, included into the project
9885 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9886 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9887 changed project type to Generic Project so that can be correcly converted to VS.NET project
9889 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9891 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9893 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9895 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9896 added return 0 statements after assert() to make compiler happy
9898 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9899 added newline in the def file to keep MSC compiler satisfied
9901 * sdcc/src/z80/gen.c:
9902 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9903 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9904 - solved MSC error in function aopDump()
9906 * sdcc_vc.h: define PREFIX as "\\sdcc"
9908 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9909 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9911 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9912 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9913 - Rewrote the register banking algorithm.
9914 - Added pCode live-range analysis to registers (for now, only non-used and
9915 singly-used registers optimized away)
9917 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9919 * 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.
9921 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9922 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9924 2002-04-22 Michael Hope <michaelh AT vroom>

9940 * src/z80/peeph.def: Added transpose redundent load rule.
9942 * src/z80/main.c: Added force callee saves for jaune.
9944 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9946 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9948 2002-03-28 Johan Knol <johan AT balder>
9950 * src/SDCCval.c: fixed bug #532436
9952 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9954 Added "char *Processor" field to the port structure.
