139 the left operand is shorter than the result (c* = lit-c* + int),
141 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
144 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
146 * src/.version: increased version number to 2.5.5
147 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
148 linking is done manually in pic16 port's _linkEdit,
149 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
150 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

152 allocate asmop as AOP_ACC,
153 (aopForRemat): added parameter 'bool result' in function declaration,
154 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

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

2580 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2581 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2582 immedDom() returning wrong block; probably fixes bug #1160833)
2584 2005-03-20 Borut Razem <borut.razem AT siol.net>
2586 * support/scripts/inc2h.pl: WIN32 port
2588 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2590 * device/lib/makefile.in: added abs.c and labs.c
2592 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2594 * device/include/stdint.h: added
2595 * device/lib/abs.c: added
2596 * device/lib/labs.c: added
2597 * device/include/stdlib.h: added abs() and labs() prototypes
2598 * device/lib/libsdcc.lib: added abs and labs
2599 * device/include/float.h,
2600 * device/lib/_fsmul.c,
2601 * device/lib/printf_fast.c,
2602 * device/lib/printf_tiny.c: updated comments
2604 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2606 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2609 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2611 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2612 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2614 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2616 * device/lib/printf_large.c: removed inline assembly for portability and
2617 readability. Use printf_fast if speed or size are more important.
2618 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2619 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2621 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2623 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2624 prevent compiler warning
2626 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2628 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2629 moved to level 0 and declared as static. Also they are explicit
2630 placed in access bank. This was necessery because some times they
2631 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2632 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2633 optimizations. Currently only compare to unsigned char is implemented,
2634 * src/pic16/gen.c: added fReturnIdx array,
2635 * (struct resolvedIfx) is moved to gen.h and made public,
2636 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2637 * (aopForSym): added an optimization to directly store in stack of
2638 the operand of a SEND iCode,
2639 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2640 but as registers instead (AOP_REG) using the fReturnIdx array,
2641 * (pic16_freeAsmop): remove the freed register from the
2642 _G.sregsAlloc field,
2643 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2644 a compare of 'WREG',
2645 * (pic16_popGetTempRegCond): changed function prototype, now
2646 function takes also a bitVector argument v which holds the current
2647 set of registers that are allocated for stack access by aopForSym,
2648 registers allocated in aopForSym for accessing stack symbols are not
2649 any more part of the functions usedRegs field,
2650 * (genCall): some times aopOp is called for a stack variable to be
2651 send, aopForSym might perform the push, if this is true make sure
2652 that genCall doesn't push the variable twice by testing _G.resDirect,
2653 * (genFunction): changed testing for unspecified interrupt number
2654 from 256 to INTNO_UNSPEC,
2655 * modified selection scheme of frame pointer generation. Previously
2656 if function did use local registers a frame pointer was generated,
2657 now a frame pointer is generated only if function has arguments
2658 (that need PLUSW2 register access), or has stack arguments, or the
2659 compiler is not instructed to omit the frame pointer,
2660 * (genEndFunction): before restoring local registers that were saved
2661 in the function preamble, also restore the registers that *might*
2662 have been allocated for stack access,
2663 * (genRet): removed some old comments,
2664 * (genCmp, the active (RN's) version): added a call to the
2665 pic16_genCmp_special function to perform the compare with a more
2666 robust and optimized way,
2667 * (genInline): a feature has been added in inline code generation,
2668 which allows a wildcard variable substitution when writing inline
2669 assembly. Code is incomplete and experimental therefore undocumented,
2670 * (genCast): changed order of aopOp for result and right to allow
2671 aopForSym to directly load the result if possible,
2672 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2673 perform an optimized compare on some selected special occasions,
2674 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2675 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2676 generate an IVT any more,
2677 * src/pic16/main.c (pic16_optionsTable): added command line option
2679 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2680 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2682 * src/pic16/NOTES: Raphael Neider added in list of active developers
2683 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2684 jumptable_end to prevent bug #,
2685 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2686 inCond and outCond fields,
2687 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2688 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2689 turn off register spilling,
2690 * (packRegsForOneUse): synced with other ports' versions although it
2691 is not used currently,
2692 * (pic16_packRegisters): added an optimization while reading
2693 structure bitfields, some registers may be saved (malloc code is
2694 decreased by 80 bytes)
2696 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2698 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2699 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2700 this can be optimized more?
2702 2005-03-10 Raphael Neider <rneider AT web.de>
2704 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2705 genNearPointerGet): (hopefully) fixed access to bitfields via
2706 pointers (p->bitN = x; and x = p->bitN; failed)
2708 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3341 generated for switch statements. For now you need to set the
3342 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3343 Now 4 algorithms for mcs51 jumptable generation are used:
3344 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3376 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3378 * added libc directory. The current version of LibC contains string
3379 functions, ctype functions and macros and some functions of the
3380 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3381 be extensively tested in the future. Standard disclaimer here.
3382 Library is not automatically build yet. But one can build it by
3383 invoking 'make' inside the libc directory.

3394 * (pic16_storeForReturn): optimized return of 0,
3395 * (genCmp): experimental code for new genCmp which uses PIC18's
3396 special compare&skip instructions. Initial tests fail some times
3397 with variables grater than 1 byte in size, so new code is disabled,
3398 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3400 * (genCast): began a fix to optimize the casting of a bit to another
3401 bit, now assigning a bitfield to another bitfield will fail, sorry,

3409 * (isBankInstruction): modified to return 0 for no banking instruction,
3410 and 1 for banking instruction,
3411 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3412 caused stop processing pCodes after a inline assembly block,
3413 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3415 registers when it shouldn't,
3416 * src/pic16/ralloc.c (allocReg): add preliminary support for
3417 supporting a limited set of temporary registers,
3419 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3425 (genFunction): optimize RECEIVE iCodes in reentrant functions
3427 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3429 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

3443 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
3445 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

6379 code / RAM are in the same page / bank. This means the linker can
6380 safely allocate code/RAM of separate ASM files to different pages/banks.
6381 * doc/sdccman.lyx: added Slade's tips
6382 * src/mcs51/peeph.def: fixed bug #880768

6424 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6426 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6427 loaded with the linker search paths (-L arguments) and the libraries
6428 to be linked with the current source (-l arguments). Changes
6429 currently will affect only the pic16 port.
6430 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6431 include path the port specific paths and port specific libraries,
6432 * gplink command now contains the $3 argument,
6433 * src/pic16/device.h,
6434 * src/pic16/device.c,: structure PIC_device is made public and
6435 renamed to PIC16_device, the same for variable Pics which is renamed

6450 Documenting changes from previous commits.
6451 * configure.in (version 1.56),
6452 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6453 when generating output files to configure the pic16 library,
6454 but now I've commented it out, since gputils aren't installed in the
6455 SF compile farm, so library won't compile
6457 * device/lib/Makefile.in (version 1.56): initially I've added in
6458 target 'all' the prerequestive 'model-pic16' so it compiled the
6459 pic16 library, but now I've commented it out for the same reasons
6461 * added targets 'model-pic16' and 'objects-pic16' to compile the
6463 * added target 'port-specific-objects-pic16' to handle the
6464 generated libraries and copy them into the build/ directory
6465 * added target 'clean-intermediate-pic16' to clean intermediate
6466 files into pic16 directory
6467 * in target 'installdirs' added line to create directory pic16 in
6468 the installation path
6470 * device/include/Makefile.in (version 1.11): in target 'install'
6471 added lines to copy all header files to installation path,
6472 * in target 'installdirs' added line create directory for pic16
6473 headers in the installation path

6488 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6489 option so that it actually works. Made it specific to the z80, since
6490 the gbz80 doesn't have these kinds of I/O ports.
6492 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6494 * device/include/z180.h,

6516 Mainly changes to support compilation of the device libraries
6517 * src/pic16/device.c: stack is allocated via symbol and not
6518 via literal number. The symbol is placed in the corresponding
6519 position of the data ram
6520 * (pic16_dump_section): relocatable and absolute uninitialized
6521 data are now emitted in sorted order to reduce section naming,
6522 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6523 weren't marked as being in the access bank,
6525 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6527 Added portion of GNU PIC Library under the directory
6528 device/include/pic16 and device/lib/pic16. These files
6529 contain the declarations of SFRs for the PIC18Fxx2 devices.
6530 The directory is initialized via configure from toplevel.
6532 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6534 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6541 2004-01-12 Borut Razem <borut.razem AT siol.net>
6543 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
6544 doc/sdccman.lyx: upper case pragmas are deprecated
6546 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6548 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6549 in simpler and even better code

6559 * doc/sdccman.lyx: Moved and added some sections, small changes
6560 all over. Telling LaTeX to be less strict with word spacing
6561 to better keep the right margin. Changed some notes about
6562 maintainance of the ports in section 3.2.1 - is it OK like this?
6564 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6566 SDCC source changes:
6567 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6573 processor registers declared internally by the port are emitted in
6574 the translation as equates,
6575 * src/pic16/gen.c: inline code is passed unprocessed to the
6577 * (pic16_popGetLit2): fnuction modified to take second operand as

6716 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6718 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6719 (default behaviour).
6721 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6723 A python script to validate compiler diagnostic messages. It can be
6724 used to verify that sdcc complains about bad c source code and
6725 gives a good location of the error.
6726 * support/valdiag/Makefile,
6727 * support/valdiag/valdiag.py,
6728 * support/valdiag/tests/*

6743 * src/common.h: added ifndef/define/endif macros
6744 around the header file.
6745 Bug reported from Jesus Calvino-Fraga
6747 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6749 * sdcc.spec: updated
6750 * device/include/Makefile.in: don't install CVS directories
6751 * device/lib/Makefile.in: added removal of CVS directories after install
6752 * doc/Makefile: fixed install, added local_icons
6753 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6754 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6755 * src/ds390/gen.c (genRightShift): fixed bug #870788
6756 * src/SDCCast.c (decorateType): fixed bug #870781
6758 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6760 PIC16 port related changes:
6761 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6762 added variable stackPos,
6764 * gen.c: genCall, assignResultValue: added support for
6765 pushing/retrieving function parameters to/from stack,
6766 genFunction,genEndFunction: setup stack frame for the
6768 genAddrOf: will be changed according to bug 863624
6770 * added files genutils.c and genutils.h which contain gen*
6771 debugged and optimised functions extracted from gen.c
6773 * glue.c: added variable 'externs' which holds extern symbols,
6774 pic16emitRegularMap: is modified to properly handle relocatable
6775 symbols under the new scheme,
6776 pic16createInterruptVect: is modified
6777 pic16printPublics: is modified to emit 'global' assembler directives,
6778 added pic16_printExterns to print extern symbols,
6779 pic16glue: initializes stack/frame pointer in the beginning of
6780 the assembly output. Temporary hack, will be corrected later,
6781 because gplink yet does not support stack and SDCC does not
6782 yet support a type of crt0.o object to create the final binary.
6784 * Removed many lines that contain 8051 legacy code.
6785 * The code is finally placed under a 'code' directive.
6786 * Added port specific options.
6788 * _process_pragma: simplified since now we do not need *special*
6789 include file to define SFR registers. But a separate header
6790 will be needed. This will be developed later.
6791 * _pic16_parseOptions: added, parses port specific options:
6792 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6793 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6794 --preplace-udata-with=
6796 * _pic16_setDefaultOptions: modified to initialize section names,
6797 but hack is temporarly out of order since it needs improvement.
6798 * _pic16_genAssemblerPreamble: configuration words are emitted by
6799 their address instead of their name. This part is incomplete and
6800 supports only the 18Fxx2 devices. Other devices will emit an error
6801 during assembly since they do not contain the same set of config
6803 * _pic16_genIVT: is modified,
6805 * pcode.c: added definitions for some hardware registers that are needed
6807 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6808 All PCI entries are updated. Now LFSR is supported.
6809 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6810 * added pic16_newpCodeOpLit2 to support instructions with
6811 two literal arguments
6812 * pic16_pCode2str: corrected code that emits assembler instructions
6813 with two literal operands and those that have an access bit modifier
6814 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6815 this fixes a bug which caused some labels to be lost, when an
6816 assembler directive was added, i.e. banksel,
6817 * pic16_FixRegisterBanking: improved logic that causes the insertion
6819 * InlineFunction: functions that are called once, are not any more
6820 inlined. This can be a port option in the future,
6822 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6824 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6825 hold the corresponding uninitialized symbols,
6826 * pic16_allocProcessorRegister: registers have explicit marked the
6828 * pic16_allocInternalRegister: registers are explicit marked as
6830 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6831 processing list, so bit registers were lost,
6834 * ralloc.h: added field 'accessBank' and original symbol operand
6835 in register definition,
6836 * removed the field isMapped from register definition,
6838 ** Several functions have been removed from various sources:
6839 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6840 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6841 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6842 pic16_assignRelocatableRegisters
6844 ** others have been introduced:
6845 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6846 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6848 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6850 * support/scripts/inc2h.pl: changed definition of BIT_AT
6851 to emit 'sbit at' instead of 'bit at'. This was a request.
6853 PIC16 port related preliminary changes:
6854 * gen.c: prefixed function popRegFromString with
6855 pic16_ and all references to it corrected
6856 * pcode.c: all pic16_pc_* hardware registers prefixed
6857 with underscore (_),
6858 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6859 * ralloc.c: newReg(): when register is REG_SFR then
6860 set address to rIdx,
6861 pic16_allocProcessorRegister(): marks register wasUsed=0
6862 pic16_writeUsedRegs(): added a call to assign processor
6863 registers via pic16_assignFixedRegisters
6865 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6867 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6868 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6869 variables in unused register banks. Also the SSEG is placed
6870 wherever there is enough space for it, and IDATA can be anywhere
6871 in internal RAM. For now compile using -Wl-Y[stack_size].
6872 The mem file is different for this option as well, since it
6873 makes no sense of talking about DSEG lenght.
6875 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6877 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6878 in certain cases, e.g. when ROM assignment, patch provided
6879 from Albert den Haan.
6881 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7022 xdata and data memory on startup. Set the environment variable
7023 SDCC_NOGENRAMCLEAR to disable this.
7024 * src/mcs51/peephole.def,
7025 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7026 (allows non-interrupt and interrupt code to safely compete for a resource
7027 without the non-interrupt code having to disable interrupts)
7029 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7767 support for standard C idiom of memory mapped variables; for
7768 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7769 to xdata int at 0x1234 tempvar = 1.
7770 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7771 provided by Akiya ISHIDA

7787 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7789 Fixed bug #621531 (const & volatile confusion in the type chain).
7790 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7870 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7871 iCode properly now. Use getSize instead of nRegs since a & b
7872 aren't part of the nRegs tally.
7874 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7876 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7882 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7883 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7884 fetching of the pointer
7885 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7886 copied from genNearPointerSet()
7887 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7888 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7889 If they pop r0/r1 they must be called in the opposite order than aopOp().
7890 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7891 (resp. --stack-auto), prepared for --xstack

7902 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7904 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7905 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7906 type for bits was changed. It resulted in bit variables becoming
7907 global, which is not permitted in PIC 14 assembly output.
7909 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7911 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7924 A few small changes that speed up the peephole optimizer.
7928 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7930 Try to make the peephole optimizer smarter by maintaining
7931 an association between the assembly source code and the
7932 iCodes that originated them. Put this information to use
7933 with a new peephole rule condition "notVolatile" so that
7934 the rules can be aggressive yet still safe.
7939 * src/mcs51/peeph.def
7941 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7945 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7946 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7947 if the left or right operand symbols have the accuse flag set.
7949 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7951 Changed the type of the result of the ! (NOT) operator to char;
7952 previously it returned the same type as the source. This allows
7953 us to eliminate all the genFloatNot functions (all of its target
7954 implementations were very buggy) since !float can use the same
7957 * src/SDCCicode.c (ast2iCode): ! returns char

7964 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7966 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7967 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7968 during interrupts. Ensure WSAVE is located at a shared bank address.
7969 2. Fixed page selection in some places
7970 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7971 the registers name strings.
7972 4. Fixed "signed / unsigned compare" compiler warnings.
7973 5. The PIC port manages its own allocation of the general purpose
7974 registers, but makes no attempt to reuse them. As a result when
7975 compiling it soon runs out of general purpose registers. Some
7976 additional code was added to the files pcode.c and device.c to walk
7977 through the function call tree and rename the registers so that they
7987 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7988 genPlus() & genMinus() when the result is the same as left or right

7994 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7996 Made bitfield a distinct type from bit so that bitfields
7997 convert as per ANSI C and bits retain their traditional
7998 boolean style behaviour. Implemented bitfield support in
8006 * src/ds390/gen.c: bit v bitfield split
8007 * src/z80/gen.c: New support for bitfields
8008 * support/regression/tests/bitfields.c: reenabled z80,
8011 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8013 Rules 246.x, 247.x relate to bitfields, the others speed up
8014 access to xdata mapped I/O devices.
8016 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8018 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8020 Cleaned up genPackBits and genUnpackBits and added two helper
8021 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8022 for literal assignments in genPackBits (thanks to Frieder for
8028 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8030 Fixed bug #748310 (pointer to function type mishandled when the
8031 function name is omitted). Also fixed a SIGSEGV when a function
8032 attribute (reentrant, etc) is used on a non-function or on a
8033 function but misplaced before the parameter list.
8035 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8037 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8038 * support/Util/SDCCerr.h,
8039 * support/Util/SDCCerr.c: Added func attr misuse error msg

8060 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8062 Made the constant following the "interrupt" keyword optional. If
8063 omitted, the function will not automatically be given an entry
8064 in the interrupt vector table (similar to #pragma NOIV, but
8065 less syntacticly kludgy). The interrupt number is also now
8066 range checked. Also fixed a bug in the high order bit example

8593 added --disable-pic16-port
8594 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8595 * src/SDCCmain.c: linkOptions is changed to set *,
8596 added if/endif conditional macros to remove options help
8597 messages from optionsTable when a port is not configured, added
8598 support for the PIc16 port in the ports table, when executing
8599 the compiler with no port specified on command line, a default
8600 port is selected with the new macro DEFAULT_PORT which is
8601 defined in port.h, in setDefaultOptions() linkOptions is removed
8602 from initialization assignment, since now it is a set,
8603 parseCmdLine uses setParseWithComma for linkOptions, in
8604 linkEdit() linkOptions are accessed with new function indexSet()
8605 which returns the i'th item of a set variable. See SDCCset.c, in
8606 linkEdit() when calling buildCmdLine(), added linkOptions as
8607 last argument. Now users can pass arguments to gplink via the
8608 -Wl option, main() uses pic16glue() to glue up pic16 programs

8620 * src/pic16/glue.c: commented out some error producing lines
8621 * src/pic16/main.c: __config directives are commented out to stop
8622 gpasm complaining and test the linkage with gplink, _linkCmd and
8623 _asmCmd changed to be more gplink and gpasm friendly
8624 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8625 produced an error when parsed, peep rule 12 is added to utilize
8626 movff, but it is commented out since the pCode does not support
8627 yet a command with 2 address arguments

9666 * src/SDCCicode.c: fixed array add
9668 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9669 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9670 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9672 2003-01-04 <johan AT balder>
9674 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9676 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9677 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9679 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9680 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9686 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9687 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9689 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9690 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9692 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9694 * in \sdcc\as\mcs51\ changed these files in order to create an
9695 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9696 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9697 following files to include the previous two files: aslink.dsp,
9698 Makefile.aslink, Makefile.bcc, and Makefile.in.
9700 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9701 .adb instead of .cdb
9703 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9705 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9706 value from option --iram-size.
9708 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9710 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9713 2002-09-18 <wiml AT hhhh.org>
9715 * SDCClrange.h: exposed setFromRange() and setToRange()
9716 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9717 packRegsForAccUse() (bug 542397)
9718 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9719 multiple times and emitting the fetch operations more than once
9720 added aopGetUsesAcc() function to allow binary operators to
9721 fetch their operands in the correct order; made genMinus() emit
9722 compact code for X = LITERAL - Y
9724 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9725 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9726 sprintf() in line 1267.
9728 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9729 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9732 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9733 Changes to aslink (All the changes are marked with 'JCF'):
9735 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9738 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9739 area BSEG. Also moves, if possible, the DATA area down into the internal
9740 ram so more space is available.
9742 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9745 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9746 not bytes. Function summary() which creates a memory usage summary
9747 file with extension .mem. Reports of overlaping stack and small stack
9748 size. If the space for the stack is less than 16 bytes aslink trows a
9751 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9752 the 8051. Option 'y' for memory summary output file.
9754 Changes to sdcc (All the changes are marked with 'JCF'):
9756 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9758 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9759 overlaying area for it (uses RegBankUsed[4]).
9761 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9762 bank zero as used by default. By default aslink locates the stack
9763 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9764 the creation of the .mem file. Delegates the allocation of data area
9765 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9766 the begining of the stack area to aslink.
9768 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9769 glue() in SDCCglue.c creates an area for it.
9771 2002-09-03 Borut Razem <borut.razem AT siol.net>
9772 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9773 sdcc/src/pic/glue.c:
9774 introduced atexit() handler for teporay files removal in case of
9775 errors, assertions, ...
9777 2002-08-29 Borut Razem <borut.razem AT siol.net>
9778 * sdcc/support/cpp2/auto-host_vc_in.h:
9779 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9780 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9781 Maybe there is a similar problem with BORLANDC? It should be checked!
9783 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9784 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9785 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9786 was not executed, and the compiler (cl) launched a warning:
9787 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9789 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9790 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9792 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9793 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9795 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9796 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9797 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9798 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9799 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9800 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9801 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9802 - added Release configuration in VS projects
9803 - review of compiler an linker options
9804 - VC .exe files are generated in bin_vc directory, not to interfere
9805 with binaries generated from other projects (cygwin, mingw, bcc ...)
9807 * sdcc/src/yacc.dsp: added
9809 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9810 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9811 and insert the version number definitions from .version
9813 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9815 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9816 added - genarate auto-host.h using auto-host_vc_in.h as template
9819 removed from CVS, generated automatically
9821 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9822 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9824 2002-08-11 Borut Razem <borut.razem AT siol.net>
9825 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9827 2002-08-10 Borut Razem <borut.razem AT siol.net>
9828 * src/SDCCmain.c (main):
9829 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9830 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9831 The consequence was that some temporary files were not removed.
9834 unification of code in functions tempfilename() and tempfile():
9835 function tempnam() is defined in Visual Studio 6.0 and .NET
9837 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9839 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9840 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9841 - removed compiler command line option /WX: Treats all warnings as errors
9842 - update a list of source files, included into the project
9844 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9845 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9846 changed project type to Generic Project so that can be correcly converted to VS.NET project
9848 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9850 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9852 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9854 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9855 added return 0 statements after assert() to make compiler happy
9857 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9858 added newline in the def file to keep MSC compiler satisfied
9860 * sdcc/src/z80/gen.c:
9861 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9862 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9863 - solved MSC error in function aopDump()
9865 * sdcc_vc.h: define PREFIX as "\\sdcc"
9867 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9868 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9870 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9871 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9872 - Rewrote the register banking algorithm.
9873 - Added pCode live-range analysis to registers (for now, only non-used and
9874 singly-used registers optimized away)
9876 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9878 * 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.
9880 2002-05-10 Scott Dattalo <scott AT dattalo.com>

9903 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9905 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9907 2002-03-28 Johan Knol <johan AT balder>
9909 * src/SDCCval.c: fixed bug #532436
9911 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9913 Added "char *Processor" field to the port structure.
9916 Added -p option. Allows port dependent processor to be specified.
9919 Initialized the new field char *Processor field to NULL in all ports
9922 Compiler generated registers for interrupt context saving
9923 were not getting allocated.
9925 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9928 Fixed left shift. Will promote the left side of a left shift
9929 if a) left shifting more than size of operand or b) when assigned
9930 to something size > size of left side
9932 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9934 tons of changes. Register allocation has been
9935 rewritten. Added customization for the various PICs. Flow
9936 analysis is restructured. ...
9942 Added. device.c is a PIC port hack to accomodate variations
9945 2002-03-13 Michael Hope <michaelh AT vroom>
9947 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9949 2002-03-04 johanknol <johanknol AT manik>
9951 * /src/SDCCval.c: fixed
9953 const unsigned char arr[][2] = { { 0, 1 } };
9954 t18.c:1: error: Initializer element is not constant
9956 2002-03-04 bela <bela AT manik>
9958 * /device/include/mcs51reg.h:
9959 ds89c420 register definition update
9961 2002-03-03 <johan AT FRIJA>
9963 * support/Util/SDCCerr.c: did something, but don't no why anymore
9965 * support/regression/tests/bug-524691.c: made it a little less shy
