172 2006-03-16 Raphael Neider <rneider AT web.de>
174 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
175 the left operand is shorter than the result (c* = lit-c* + int),
177 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
180 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
182 * src/.version: increased version number to 2.5.5
183 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
184 linking is done manually in pic16 port's _linkEdit,
185 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
186 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
187 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
188 allocate asmop as AOP_ACC,
189 (aopForRemat): added parameter 'bool result' in function declaration,
190 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

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

2620 2005-03-20 Borut Razem <borut.razem AT siol.net>
2622 * support/scripts/inc2h.pl: WIN32 port
2624 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2626 * device/lib/makefile.in: added abs.c and labs.c
2628 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2630 * device/include/stdint.h: added
2631 * device/lib/abs.c: added
2632 * device/lib/labs.c: added
2633 * device/include/stdlib.h: added abs() and labs() prototypes

2640 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2642 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

2648 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2650 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2652 * device/lib/printf_large.c: removed inline assembly for portability and
2653 readability. Use printf_fast if speed or size are more important.
2654 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2655 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2657 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2659 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2660 prevent compiler warning
2662 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2664 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2665 moved to level 0 and declared as static. Also they are explicit
2666 placed in access bank. This was necessery because some times they
2667 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2668 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2669 optimizations. Currently only compare to unsigned char is implemented,
2670 * src/pic16/gen.c: added fReturnIdx array,
2671 * (struct resolvedIfx) is moved to gen.h and made public,
2672 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2673 * (aopForSym): added an optimization to directly store in stack of
2674 the operand of a SEND iCode,
2675 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2676 but as registers instead (AOP_REG) using the fReturnIdx array,
2677 * (pic16_freeAsmop): remove the freed register from the
2678 _G.sregsAlloc field,
2679 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2680 a compare of 'WREG',
2681 * (pic16_popGetTempRegCond): changed function prototype, now
2682 function takes also a bitVector argument v which holds the current
2683 set of registers that are allocated for stack access by aopForSym,
2684 registers allocated in aopForSym for accessing stack symbols are not
2685 any more part of the functions usedRegs field,
2686 * (genCall): some times aopOp is called for a stack variable to be
2687 send, aopForSym might perform the push, if this is true make sure
2688 that genCall doesn't push the variable twice by testing _G.resDirect,
2689 * (genFunction): changed testing for unspecified interrupt number
2690 from 256 to INTNO_UNSPEC,
2691 * modified selection scheme of frame pointer generation. Previously
2692 if function did use local registers a frame pointer was generated,
2693 now a frame pointer is generated only if function has arguments
2694 (that need PLUSW2 register access), or has stack arguments, or the
2695 compiler is not instructed to omit the frame pointer,
2696 * (genEndFunction): before restoring local registers that were saved
2697 in the function preamble, also restore the registers that *might*
2698 have been allocated for stack access,
2699 * (genRet): removed some old comments,
2700 * (genCmp, the active (RN's) version): added a call to the
2701 pic16_genCmp_special function to perform the compare with a more
2702 robust and optimized way,
2703 * (genInline): a feature has been added in inline code generation,
2704 which allows a wildcard variable substitution when writing inline
2705 assembly. Code is incomplete and experimental therefore undocumented,
2706 * (genCast): changed order of aopOp for result and right to allow
2707 aopForSym to directly load the result if possible,
2708 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2709 perform an optimized compare on some selected special occasions,
2710 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2711 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2712 generate an IVT any more,
2713 * src/pic16/main.c (pic16_optionsTable): added command line option
2715 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2716 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2718 * src/pic16/NOTES: Raphael Neider added in list of active developers
2719 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2720 jumptable_end to prevent bug #,
2721 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2722 inCond and outCond fields,
2723 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2724 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2725 turn off register spilling,
2726 * (packRegsForOneUse): synced with other ports' versions although it
2727 is not used currently,
2728 * (pic16_packRegisters): added an optimization while reading
2729 structure bitfields, some registers may be saved (malloc code is
2730 decreased by 80 bytes)
2732 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2734 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2735 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2736 this can be optimized more?
2738 2005-03-10 Raphael Neider <rneider AT web.de>
2740 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2741 genNearPointerGet): (hopefully) fixed access to bitfields via
2742 pointers (p->bitN = x; and x = p->bitN; failed)
2744 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2746 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2932 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2933 this might fix SIGSEGVs on MinGW...
2934 * src/SDCCopt.c (killDeadCode): restored original behaviour
2935 (volatile operands might get thrown away though)
2937 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3377 generated for switch statements. For now you need to set the
3378 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3379 Now 4 algorithms for mcs51 jumptable generation are used:
3380 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3381 addresses loaded pc-relative for up to 112 cases and stack-pushing
3382 target addresses loaded with offset from dptr for up to 256 cases.

3412 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3414 * added libc directory. The current version of LibC contains string
3415 functions, ctype functions and macros and some functions of the
3416 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3417 be extensively tested in the future. Standard disclaimer here.
3418 Library is not automatically build yet. But one can build it by
3419 invoking 'make' inside the libc directory.
3420 * added ADC library under libio. Preliminary version yet.

3429 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3430 * (pic16_storeForReturn): optimized return of 0,
3431 * (genCmp): experimental code for new genCmp which uses PIC18's
3432 special compare&skip instructions. Initial tests fail some times
3433 with variables grater than 1 byte in size, so new code is disabled,
3434 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3436 * (genCast): began a fix to optimize the casting of a bit to another
3437 bit, now assigning a bitfield to another bitfield will fail, sorry,

3442 bits with offset (case PO_GPR_BIT),
3443 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3445 * (isBankInstruction): modified to return 0 for no banking instruction,
3446 and 1 for banking instruction,
3447 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

6460 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6462 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6463 loaded with the linker search paths (-L arguments) and the libraries
6464 to be linked with the current source (-l arguments). Changes
6465 currently will affect only the pic16 port.
6466 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6467 include path the port specific paths and port specific libraries,
6468 * gplink command now contains the $3 argument,
6469 * src/pic16/device.h,
6470 * src/pic16/device.c,: structure PIC_device is made public and
6471 renamed to PIC16_device, the same for variable Pics which is renamed

6486 Documenting changes from previous commits.
6487 * configure.in (version 1.56),
6488 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6489 when generating output files to configure the pic16 library,
6490 but now I've commented it out, since gputils aren't installed in the
6491 SF compile farm, so library won't compile
6493 * device/lib/Makefile.in (version 1.56): initially I've added in
6494 target 'all' the prerequestive 'model-pic16' so it compiled the
6495 pic16 library, but now I've commented it out for the same reasons
6497 * added targets 'model-pic16' and 'objects-pic16' to compile the
6499 * added target 'port-specific-objects-pic16' to handle the
6500 generated libraries and copy them into the build/ directory
6501 * added target 'clean-intermediate-pic16' to clean intermediate
6502 files into pic16 directory
6503 * in target 'installdirs' added line to create directory pic16 in
6504 the installation path
6506 * device/include/Makefile.in (version 1.11): in target 'install'
6507 added lines to copy all header files to installation path,
6508 * in target 'installdirs' added line create directory for pic16
6509 headers in the installation path

6525 option so that it actually works. Made it specific to the z80, since
6526 the gbz80 doesn't have these kinds of I/O ports.
6528 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6530 * device/include/z180.h,

6559 weren't marked as being in the access bank,
6561 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6563 Added portion of GNU PIC Library under the directory
6564 device/include/pic16 and device/lib/pic16. These files
6565 contain the declarations of SFRs for the PIC18Fxx2 devices.
6566 The directory is initialized via configure from toplevel.
6568 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

6596 all over. Telling LaTeX to be less strict with word spacing
6597 to better keep the right margin. Changed some notes about
6598 maintainance of the ports in section 3.2.1 - is it OK like this?
6600 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6638 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6640 * src/pic16/peeph.def: all peepholes with movff are commented out,
6641 because there is a problem in the pcode peep optimizer,
6642 * src/pic16/ralloc.c: the register allocator can now reuse local

6679 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6682 * src/z80/main.c: added missed needLinkerScript flags (more than
6683 one port structure defined in these file)
6684 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6719 2004-01-07 Borut Razem <borut.razem AT siol.net>
6721 * support/scripts/sdcc.nsi: update PATH
6722 * support/scripts/sdcc.ico: craeted

6735 include information about variables allocated to the overlay
6738 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6740 * as/mcs51/lkmain.c: Help about -Y option

6752 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6754 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6755 (default behaviour).
6757 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6759 A python script to validate compiler diagnostic messages. It can be
6760 used to verify that sdcc complains about bad c source code and
6761 gives a good location of the error.
6762 * support/valdiag/Makefile,
6763 * support/valdiag/valdiag.py,
6764 * support/valdiag/tests/*
6766 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6768 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6779 * src/common.h: added ifndef/define/endif macros
6780 around the header file.
6781 Bug reported from Jesus Calvino-Fraga
6783 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6785 * sdcc.spec: updated
6786 * device/include/Makefile.in: don't install CVS directories
6787 * device/lib/Makefile.in: added removal of CVS directories after install
6788 * doc/Makefile: fixed install, added local_icons
6789 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6790 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6791 * src/ds390/gen.c (genRightShift): fixed bug #870788
6792 * src/SDCCast.c (decorateType): fixed bug #870781
6794 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6796 PIC16 port related changes:
6797 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6798 added variable stackPos,
6800 * gen.c: genCall, assignResultValue: added support for
6801 pushing/retrieving function parameters to/from stack,
6802 genFunction,genEndFunction: setup stack frame for the
6804 genAddrOf: will be changed according to bug 863624
6806 * added files genutils.c and genutils.h which contain gen*
6807 debugged and optimised functions extracted from gen.c
6809 * glue.c: added variable 'externs' which holds extern symbols,
6810 pic16emitRegularMap: is modified to properly handle relocatable
6811 symbols under the new scheme,
6812 pic16createInterruptVect: is modified
6813 pic16printPublics: is modified to emit 'global' assembler directives,
6814 added pic16_printExterns to print extern symbols,
6815 pic16glue: initializes stack/frame pointer in the beginning of
6816 the assembly output. Temporary hack, will be corrected later,
6817 because gplink yet does not support stack and SDCC does not
6818 yet support a type of crt0.o object to create the final binary.
6820 * Removed many lines that contain 8051 legacy code.
6821 * The code is finally placed under a 'code' directive.
6822 * Added port specific options.
6824 * _process_pragma: simplified since now we do not need *special*
6825 include file to define SFR registers. But a separate header
6826 will be needed. This will be developed later.
6827 * _pic16_parseOptions: added, parses port specific options:
6828 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6829 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6830 --preplace-udata-with=
6832 * _pic16_setDefaultOptions: modified to initialize section names,
6833 but hack is temporarly out of order since it needs improvement.
6834 * _pic16_genAssemblerPreamble: configuration words are emitted by
6835 their address instead of their name. This part is incomplete and
6836 supports only the 18Fxx2 devices. Other devices will emit an error
6837 during assembly since they do not contain the same set of config
6839 * _pic16_genIVT: is modified,
6841 * pcode.c: added definitions for some hardware registers that are needed
6843 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6844 All PCI entries are updated. Now LFSR is supported.
6845 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6846 * added pic16_newpCodeOpLit2 to support instructions with
6847 two literal arguments
6848 * pic16_pCode2str: corrected code that emits assembler instructions
6849 with two literal operands and those that have an access bit modifier
6850 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6851 this fixes a bug which caused some labels to be lost, when an
6852 assembler directive was added, i.e. banksel,
6853 * pic16_FixRegisterBanking: improved logic that causes the insertion
6855 * InlineFunction: functions that are called once, are not any more
6856 inlined. This can be a port option in the future,
6858 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6860 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6861 hold the corresponding uninitialized symbols,
6862 * pic16_allocProcessorRegister: registers have explicit marked the
6864 * pic16_allocInternalRegister: registers are explicit marked as
6866 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6867 processing list, so bit registers were lost,
6870 * ralloc.h: added field 'accessBank' and original symbol operand
6871 in register definition,
6872 * removed the field isMapped from register definition,
6874 ** Several functions have been removed from various sources:
6875 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6876 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6877 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6878 pic16_assignRelocatableRegisters
6880 ** others have been introduced:
6881 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6882 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6884 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6886 * support/scripts/inc2h.pl: changed definition of BIT_AT
6887 to emit 'sbit at' instead of 'bit at'. This was a request.
6889 PIC16 port related preliminary changes:
6890 * gen.c: prefixed function popRegFromString with
6891 pic16_ and all references to it corrected
6892 * pcode.c: all pic16_pc_* hardware registers prefixed
6893 with underscore (_),
6894 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6895 * ralloc.c: newReg(): when register is REG_SFR then
6896 set address to rIdx,
6897 pic16_allocProcessorRegister(): marks register wasUsed=0
6898 pic16_writeUsedRegs(): added a call to assign processor
6899 registers via pic16_assignFixedRegisters
6901 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6903 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6904 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6905 variables in unused register banks. Also the SSEG is placed
6906 wherever there is enough space for it, and IDATA can be anywhere
6907 in internal RAM. For now compile using -Wl-Y[stack_size].
6908 The mem file is different for this option as well, since it
6909 makes no sense of talking about DSEG lenght.
6911 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6913 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6914 in certain cases, e.g. when ROM assignment, patch provided
6915 from Albert den Haan.
6917 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7063 without the non-interrupt code having to disable interrupts)
7065 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7067 * src/SDCCicode.c (geniCodeAdd),

7940 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7941 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7942 type for bits was changed. It resulted in bit variables becoming
7943 global, which is not permitted in PIC 14 assembly output.

7960 A few small changes that speed up the peephole optimizer.
7964 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7966 Try to make the peephole optimizer smarter by maintaining
7967 an association between the assembly source code and the
7968 iCodes that originated them. Put this information to use
7969 with a new peephole rule condition "notVolatile" so that
7970 the rules can be aggressive yet still safe.
7975 * src/mcs51/peeph.def
7977 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7981 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7982 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7983 if the left or right operand symbols have the accuse flag set.
7985 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7987 Changed the type of the result of the ! (NOT) operator to char;
7988 previously it returned the same type as the source. This allows
7989 us to eliminate all the genFloatNot functions (all of its target
7990 implementations were very buggy) since !float can use the same
7993 * src/SDCCicode.c (ast2iCode): ! returns char

8002 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8003 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8004 during interrupts. Ensure WSAVE is located at a shared bank address.
8005 2. Fixed page selection in some places
8006 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8007 the registers name strings.
8008 4. Fixed "signed / unsigned compare" compiler warnings.
8009 5. The PIC port manages its own allocation of the general purpose
8010 registers, but makes no attempt to reuse them. As a result when
8011 compiling it soon runs out of general purpose registers. Some
8012 additional code was added to the files pcode.c and device.c to walk
8013 through the function call tree and rename the registers so that they
8023 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8024 genPlus() & genMinus() when the result is the same as left or right

8030 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8032 Made bitfield a distinct type from bit so that bitfields
8033 convert as per ANSI C and bits retain their traditional
8034 boolean style behaviour. Implemented bitfield support in
8042 * src/ds390/gen.c: bit v bitfield split
8043 * src/z80/gen.c: New support for bitfields
8044 * support/regression/tests/bitfields.c: reenabled z80,
8047 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8049 Rules 246.x, 247.x relate to bitfields, the others speed up
8050 access to xdata mapped I/O devices.
8052 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8054 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8056 Cleaned up genPackBits and genUnpackBits and added two helper
8057 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8058 for literal assignments in genPackBits (thanks to Frieder for
8064 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8066 Fixed bug #748310 (pointer to function type mishandled when the
8067 function name is omitted). Also fixed a SIGSEGV when a function
8068 attribute (reentrant, etc) is used on a non-function or on a

8099 omitted, the function will not automatically be given an entry
8100 in the interrupt vector table (similar to #pragma NOIV, but

8638 from initialization assignment, since now it is a set,
8639 parseCmdLine uses setParseWithComma for linkOptions, in
8640 linkEdit() linkOptions are accessed with new function indexSet()
8641 which returns the i'th item of a set variable. See SDCCset.c, in
8642 linkEdit() when calling buildCmdLine(), added linkOptions as
8643 last argument. Now users can pass arguments to gplink via the
8644 -Wl option, main() uses pic16glue() to glue up pic16 programs

8658 gpasm complaining and test the linkage with gplink, _linkCmd and
8659 _asmCmd changed to be more gplink and gpasm friendly
8660 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8661 produced an error when parsed, peep rule 12 is added to utilize
8662 movff, but it is commented out since the pCode does not support
8663 yet a command with 2 address arguments

9702 * src/SDCCicode.c: fixed array add
9704 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9705 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9706 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9708 2003-01-04 <johan AT balder>
9710 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9712 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9713 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9715 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9716 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9725 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9726 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9728 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9730 * in \sdcc\as\mcs51\ changed these files in order to create an
9731 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9732 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9733 following files to include the previous two files: aslink.dsp,
9734 Makefile.aslink, Makefile.bcc, and Makefile.in.
9736 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9737 .adb instead of .cdb
9739 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9741 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9742 value from option --iram-size.
9744 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9746 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9749 2002-09-18 <wiml AT hhhh.org>
9751 * SDCClrange.h: exposed setFromRange() and setToRange()
9752 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9753 packRegsForAccUse() (bug 542397)
9754 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9755 multiple times and emitting the fetch operations more than once
9756 added aopGetUsesAcc() function to allow binary operators to
9757 fetch their operands in the correct order; made genMinus() emit
9758 compact code for X = LITERAL - Y
9760 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9761 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9762 sprintf() in line 1267.
9764 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9765 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9768 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9769 Changes to aslink (All the changes are marked with 'JCF'):
9771 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9774 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9775 area BSEG. Also moves, if possible, the DATA area down into the internal
9776 ram so more space is available.
9778 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9781 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9782 not bytes. Function summary() which creates a memory usage summary
9783 file with extension .mem. Reports of overlaping stack and small stack
9784 size. If the space for the stack is less than 16 bytes aslink trows a
9787 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9788 the 8051. Option 'y' for memory summary output file.
9790 Changes to sdcc (All the changes are marked with 'JCF'):
9792 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9794 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9795 overlaying area for it (uses RegBankUsed[4]).
9797 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9798 bank zero as used by default. By default aslink locates the stack
9799 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9800 the creation of the .mem file. Delegates the allocation of data area
9801 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9802 the begining of the stack area to aslink.
9804 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9805 glue() in SDCCglue.c creates an area for it.
9807 2002-09-03 Borut Razem <borut.razem AT siol.net>
9808 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9809 sdcc/src/pic/glue.c:
9810 introduced atexit() handler for teporay files removal in case of
9811 errors, assertions, ...
9813 2002-08-29 Borut Razem <borut.razem AT siol.net>
9814 * sdcc/support/cpp2/auto-host_vc_in.h:
9815 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9816 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9817 Maybe there is a similar problem with BORLANDC? It should be checked!
9819 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9820 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9821 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9822 was not executed, and the compiler (cl) launched a warning:
9823 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9825 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9826 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9828 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9829 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9831 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9832 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9833 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9834 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9835 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9836 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9837 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9838 - added Release configuration in VS projects
9839 - review of compiler an linker options
9840 - VC .exe files are generated in bin_vc directory, not to interfere
9841 with binaries generated from other projects (cygwin, mingw, bcc ...)
9843 * sdcc/src/yacc.dsp: added
9845 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9846 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9847 and insert the version number definitions from .version
9849 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9851 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9852 added - genarate auto-host.h using auto-host_vc_in.h as template
9855 removed from CVS, generated automatically
9857 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9858 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9860 2002-08-11 Borut Razem <borut.razem AT siol.net>
9861 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9863 2002-08-10 Borut Razem <borut.razem AT siol.net>
9864 * src/SDCCmain.c (main):
9865 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9866 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9867 The consequence was that some temporary files were not removed.
9870 unification of code in functions tempfilename() and tempfile():
9871 function tempnam() is defined in Visual Studio 6.0 and .NET
9873 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9875 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9876 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9877 - removed compiler command line option /WX: Treats all warnings as errors
9878 - update a list of source files, included into the project
9880 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9881 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9882 changed project type to Generic Project so that can be correcly converted to VS.NET project
9884 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9886 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9888 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9890 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9891 added return 0 statements after assert() to make compiler happy
9893 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9894 added newline in the def file to keep MSC compiler satisfied
9896 * sdcc/src/z80/gen.c:
9897 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9898 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9899 - solved MSC error in function aopDump()
9901 * sdcc_vc.h: define PREFIX as "\\sdcc"
9903 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9904 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9906 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9907 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9908 - Rewrote the register banking algorithm.
9909 - Added pCode live-range analysis to registers (for now, only non-used and
9910 singly-used registers optimized away)
9912 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9914 * 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.
9916 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9917 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9919 2002-04-22 Michael Hope <michaelh AT vroom>

9939 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9941 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9943 2002-03-28 Johan Knol <johan AT balder>
9945 * src/SDCCval.c: fixed bug #532436
9947 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9949 Added "char *Processor" field to the port structure.
