5 2006-03-23 Maarten Brock <sourceforge.brock AT dse.nl>
7 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
8 implemented patch 1120823 Thanks to Willy De la Court (normal
9 interrupts need an interrupt number now if they are made critical),
10 and enabled nesting of critical functions though not for gbz80
11 (genCritical, genEndCritical): added functions
12 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
13 * src/z80/mappings.i: added "ei" to all mappings
15 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
17 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
18 submitted by the Debian SDCC maintainer Aurelien Jarno:
19 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
20 archive with gcc 4.1 on mips and wrote the patch"
22 2006-03-16 Raphael Neider <rneider AT web.de>
24 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
25 the left operand is shorter than the result (c* = lit-c* + int),
27 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
30 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
32 * src/.version: increased version number to 2.5.5
33 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
34 linking is done manually in pic16 port's _linkEdit,
35 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
36 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
37 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
38 allocate asmop as AOP_ACC,
39 (aopForRemat): added parameter 'bool result' in function declaration,
40 (pic16_aopGet): return AOP_ACC when accessing WREG,
41 (pic16_popGetTempReg): minor modification,
42 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
44 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
45 calling function in absolute addresses,
46 (genAssign): take into account AOP_ACC asmop,
47 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
48 * src/pic16/pcoderegs.c: some debug functions and lines added,
49 * src/pic16/ralloc.c (decodeRegType): added but commented out,
50 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
52 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
53 call to allocReg, not by manually allocating a new one,
54 (pic16_assignRegisters): now before going through the register
55 allocating functions mark all registers as free. This eliminates some
56 side effects resulting from peephole parser done earlier in the backbone
58 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
60 * src/SDCCicode.c (geniCodeLogic),
61 * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

79 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
80 (aopForSym, aopOp): increment asmop.allocated if reused,
81 (freeAsmop): decrement asmop.allocated and check for zero instead of
83 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
84 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
85 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

106 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
108 2006-03-06 Borut Razem <borut.razem AT siol.net>
110 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
111 made the linker quiet
113 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
115 * src/pic16/gen.c (genPcall): fixed bug #1443644
116 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
117 which dumps before the function entry point a data byte which represents
118 the number of the local variables used by the specified function, added
119 'xinst' for initial support for Extended Instruction Support,
120 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
121 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
122 port->fun_prefix anymore (may change later),
123 (genFunction, genEndFunction): do not store/restore local registers for
124 _main (this should take care the --main-return command line option in
126 (genOr): removed some legacy pic-port instructions,
127 * src/pic16/genarith.c (genAddLit): re-enabled old code because
128 performing operations with SFR's causes data to be written more than
129 once to each SFR. Perhaps SFRs should be handled in special cases...
130 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
132 * src/pic16/main.c (_process_pragma): stack bound checking did not take
133 into account for stack starting position,
134 (struct OPTIONS pic16_optionsTable): added command line argument
135 --extended or -y for Extended Instruction Support,
136 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
137 (deassignLRs): *** perhaps the most important change, old 'for' code
138 (commented out for reference), didn't account for some registers which
139 were left marked 'not free' after a pointer operation. The change
140 reduces register usage a lot in some cases

2498 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2500 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2502 * device/lib/printf_large.c: removed inline assembly for portability and
2503 readability. Use printf_fast if speed or size are more important.
2504 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2505 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2507 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2509 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2510 prevent compiler warning
2512 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2514 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2515 moved to level 0 and declared as static. Also they are explicit
2516 placed in access bank. This was necessery because some times they
2517 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2518 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2519 optimizations. Currently only compare to unsigned char is implemented,
2520 * src/pic16/gen.c: added fReturnIdx array,
2521 * (struct resolvedIfx) is moved to gen.h and made public,
2522 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2523 * (aopForSym): added an optimization to directly store in stack of
2524 the operand of a SEND iCode,
2525 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2526 but as registers instead (AOP_REG) using the fReturnIdx array,
2527 * (pic16_freeAsmop): remove the freed register from the
2528 _G.sregsAlloc field,
2529 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2530 a compare of 'WREG',
2531 * (pic16_popGetTempRegCond): changed function prototype, now
2532 function takes also a bitVector argument v which holds the current
2533 set of registers that are allocated for stack access by aopForSym,
2534 registers allocated in aopForSym for accessing stack symbols are not
2535 any more part of the functions usedRegs field,
2536 * (genCall): some times aopOp is called for a stack variable to be
2537 send, aopForSym might perform the push, if this is true make sure
2538 that genCall doesn't push the variable twice by testing _G.resDirect,
2539 * (genFunction): changed testing for unspecified interrupt number
2540 from 256 to INTNO_UNSPEC,
2541 * modified selection scheme of frame pointer generation. Previously
2542 if function did use local registers a frame pointer was generated,
2543 now a frame pointer is generated only if function has arguments
2544 (that need PLUSW2 register access), or has stack arguments, or the
2545 compiler is not instructed to omit the frame pointer,
2546 * (genEndFunction): before restoring local registers that were saved
2547 in the function preamble, also restore the registers that *might*
2548 have been allocated for stack access,
2549 * (genRet): removed some old comments,
2550 * (genCmp, the active (RN's) version): added a call to the
2551 pic16_genCmp_special function to perform the compare with a more
2552 robust and optimized way,
2553 * (genInline): a feature has been added in inline code generation,
2554 which allows a wildcard variable substitution when writing inline
2555 assembly. Code is incomplete and experimental therefore undocumented,
2556 * (genCast): changed order of aopOp for result and right to allow
2557 aopForSym to directly load the result if possible,
2558 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2559 perform an optimized compare on some selected special occasions,
2560 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2561 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2562 generate an IVT any more,
2563 * src/pic16/main.c (pic16_optionsTable): added command line option
2565 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2566 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2568 * src/pic16/NOTES: Raphael Neider added in list of active developers
2569 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2570 jumptable_end to prevent bug #,
2571 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2572 inCond and outCond fields,
2573 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2574 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2575 turn off register spilling,
2576 * (packRegsForOneUse): synced with other ports' versions although it
2577 is not used currently,
2578 * (pic16_packRegisters): added an optimization while reading
2579 structure bitfields, some registers may be saved (malloc code is
2580 decreased by 80 bytes)

3226 Adding support for replacing ljmps with sjmps in jumptables
3227 generated for switch statements. For now you need to set the
3228 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3229 Now 4 algorithms for mcs51 jumptable generation are used:
3230 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3231 addresses loaded pc-relative for up to 112 cases and stack-pushing
3232 target addresses loaded with offset from dptr for up to 256 cases.

3262 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3264 * added libc directory. The current version of LibC contains string
3265 functions, ctype functions and macros and some functions of the
3266 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3267 be extensively tested in the future. Standard disclaimer here.
3268 Library is not automatically build yet. But one can build it by
3269 invoking 'make' inside the libc directory.

3280 * (pic16_storeForReturn): optimized return of 0,
3281 * (genCmp): experimental code for new genCmp which uses PIC18's
3282 special compare&skip instructions. Initial tests fail some times
3283 with variables grater than 1 byte in size, so new code is disabled,
3284 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3286 * (genCast): began a fix to optimize the casting of a bit to another
3287 bit, now assigning a bitfield to another bitfield will fail, sorry,

3296 and 1 for banking instruction,
3297 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3298 caused stop processing pCodes after a inline assembly block,
3299 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3301 registers when it shouldn't,
3302 * src/pic16/ralloc.c (allocReg): add preliminary support for
3303 supporting a limited set of temporary registers,
3305 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3311 (genFunction): optimize RECEIVE iCodes in reentrant functions
3313 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6313 loaded with the linker search paths (-L arguments) and the libraries
6314 to be linked with the current source (-l arguments). Changes
6315 currently will affect only the pic16 port.
6316 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6317 include path the port specific paths and port specific libraries,
6318 * gplink command now contains the $3 argument,
6319 * src/pic16/device.h,

6336 Documenting changes from previous commits.
6337 * configure.in (version 1.56),
6338 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6339 when generating output files to configure the pic16 library,
6340 but now I've commented it out, since gputils aren't installed in the
6341 SF compile farm, so library won't compile
6343 * device/lib/Makefile.in (version 1.56): initially I've added in
6344 target 'all' the prerequestive 'model-pic16' so it compiled the
6345 pic16 library, but now I've commented it out for the same reasons
6347 * added targets 'model-pic16' and 'objects-pic16' to compile the
6349 * added target 'port-specific-objects-pic16' to handle the
6350 generated libraries and copy them into the build/ directory
6351 * added target 'clean-intermediate-pic16' to clean intermediate
6352 files into pic16 directory
6353 * in target 'installdirs' added line to create directory pic16 in

6357 added lines to copy all header files to installation path,
6358 * in target 'installdirs' added line create directory for pic16
6359 headers in the installation path

6591 * as/mcs51/lkarea.c: Fixed gcc warnings
6593 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6595 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
6597 * support/valdiag/tests/overflow.c: added
6598 * src/SDCCast.c (decorateType),
6599 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6600 LEFT_OP (left shift)
6602 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6604 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6605 (default behaviour).
6607 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6609 A python script to validate compiler diagnostic messages. It can be
6610 used to verify that sdcc complains about bad c source code and
6611 gives a good location of the error.
6612 * support/valdiag/Makefile,
6613 * support/valdiag/valdiag.py,
6614 * support/valdiag/tests/*
6616 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6618 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6619 * src/SDCCsymt.c (newEnumType),
6621 * support/Util/SDCCerr.c,
6622 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6624 * support/regression/tests/enum.c: added test for enum values that
6625 require at least 2 bytes of storage.
6627 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6629 * src/common.h: added ifndef/define/endif macros
6630 around the header file.
6631 Bug reported from Jesus Calvino-Fraga
6633 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6635 * sdcc.spec: updated
6636 * device/include/Makefile.in: don't install CVS directories
6637 * device/lib/Makefile.in: added removal of CVS directories after install
6638 * doc/Makefile: fixed install, added local_icons
6639 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6640 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6641 * src/ds390/gen.c (genRightShift): fixed bug #870788
6642 * src/SDCCast.c (decorateType): fixed bug #870781
6644 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6646 PIC16 port related changes:
6647 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6648 added variable stackPos,
6650 * gen.c: genCall, assignResultValue: added support for
6651 pushing/retrieving function parameters to/from stack,
6652 genFunction,genEndFunction: setup stack frame for the
6654 genAddrOf: will be changed according to bug 863624
6656 * added files genutils.c and genutils.h which contain gen*
6657 debugged and optimised functions extracted from gen.c
6659 * glue.c: added variable 'externs' which holds extern symbols,
6660 pic16emitRegularMap: is modified to properly handle relocatable
6661 symbols under the new scheme,
6662 pic16createInterruptVect: is modified
6663 pic16printPublics: is modified to emit 'global' assembler directives,
6664 added pic16_printExterns to print extern symbols,
6665 pic16glue: initializes stack/frame pointer in the beginning of
6666 the assembly output. Temporary hack, will be corrected later,
6667 because gplink yet does not support stack and SDCC does not
6668 yet support a type of crt0.o object to create the final binary.
6670 * Removed many lines that contain 8051 legacy code.
6671 * The code is finally placed under a 'code' directive.
6672 * Added port specific options.
6674 * _process_pragma: simplified since now we do not need *special*
6675 include file to define SFR registers. But a separate header
6676 will be needed. This will be developed later.
6677 * _pic16_parseOptions: added, parses port specific options:
6678 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6679 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6680 --preplace-udata-with=
6682 * _pic16_setDefaultOptions: modified to initialize section names,
6683 but hack is temporarly out of order since it needs improvement.
6684 * _pic16_genAssemblerPreamble: configuration words are emitted by
6685 their address instead of their name. This part is incomplete and
6686 supports only the 18Fxx2 devices. Other devices will emit an error
6687 during assembly since they do not contain the same set of config
6689 * _pic16_genIVT: is modified,
6691 * pcode.c: added definitions for some hardware registers that are needed
6693 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6694 All PCI entries are updated. Now LFSR is supported.
6695 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6696 * added pic16_newpCodeOpLit2 to support instructions with
6697 two literal arguments
6698 * pic16_pCode2str: corrected code that emits assembler instructions
6699 with two literal operands and those that have an access bit modifier
6700 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6701 this fixes a bug which caused some labels to be lost, when an
6702 assembler directive was added, i.e. banksel,
6703 * pic16_FixRegisterBanking: improved logic that causes the insertion
6705 * InlineFunction: functions that are called once, are not any more
6706 inlined. This can be a port option in the future,
6708 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6710 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6711 hold the corresponding uninitialized symbols,
6712 * pic16_allocProcessorRegister: registers have explicit marked the
6714 * pic16_allocInternalRegister: registers are explicit marked as
6716 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6717 processing list, so bit registers were lost,
6720 * ralloc.h: added field 'accessBank' and original symbol operand
6721 in register definition,
6722 * removed the field isMapped from register definition,
6724 ** Several functions have been removed from various sources:
6725 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6726 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6727 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6728 pic16_assignRelocatableRegisters
6730 ** others have been introduced:
6731 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6732 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6734 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6736 * support/scripts/inc2h.pl: changed definition of BIT_AT
6737 to emit 'sbit at' instead of 'bit at'. This was a request.
6739 PIC16 port related preliminary changes:
6740 * gen.c: prefixed function popRegFromString with
6741 pic16_ and all references to it corrected
6742 * pcode.c: all pic16_pc_* hardware registers prefixed
6743 with underscore (_),
6744 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6745 * ralloc.c: newReg(): when register is REG_SFR then
6746 set address to rIdx,
6747 pic16_allocProcessorRegister(): marks register wasUsed=0
6748 pic16_writeUsedRegs(): added a call to assign processor
6749 registers via pic16_assignFixedRegisters
6751 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6753 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6754 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6755 variables in unused register banks. Also the SSEG is placed
6756 wherever there is enough space for it, and IDATA can be anywhere
6757 in internal RAM. For now compile using -Wl-Y[stack_size].
6758 The mem file is different for this option as well, since it
6759 makes no sense of talking about DSEG lenght.
6761 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6763 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6764 in certain cases, e.g. when ROM assignment, patch provided
6765 from Albert den Haan.
6767 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6910 * src/mcs51/peephole.def,
6911 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6923 multiply defined with mismatching "at" address.
6925 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6927 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

7006 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7008 * src/SDCCast.c (decorateType): disabled a transformation I added in
7009 revision 1.188 (access to fields of a structure at an absolute address);
7010 it breaks with bitfields, extern declarations, and gcse analysis.
7011 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7012 could be assigned through a pointer, so don't complain.
7013 * src/SDCCast.c (astErrors),
7015 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7650 * src/SDCCsymt.c (sclsFromPtr),
7652 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7653 support for standard C idiom of memory mapped variables; for
7654 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7655 to xdata int at 0x1234 tempvar = 1.
7656 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7657 provided by Akiya ISHIDA

7673 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7675 Fixed bug #621531 (const & volatile confusion in the type chain).
7676 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7677 refer to the const or volatile state of the pointer itself.

7768 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7769 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7770 fetching of the pointer
7771 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7772 copied from genNearPointerSet()
7773 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7774 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7775 If they pop r0/r1 they must be called in the opposite order than aopOp().
7776 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7777 (resp. --stack-auto), prepared for --xstack

7788 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7790 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7791 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7792 type for bits was changed. It resulted in bit variables becoming
7793 global, which is not permitted in PIC 14 assembly output.
7795 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7797 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7799 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7801 Z80 and MCS51 linkers complaint if a public symbol is defined

7810 A few small changes that speed up the peephole optimizer.
7814 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7816 Try to make the peephole optimizer smarter by maintaining
7817 an association between the assembly source code and the
7818 iCodes that originated them. Put this information to use
7819 with a new peephole rule condition "notVolatile" so that
7820 the rules can be aggressive yet still safe.
7825 * src/mcs51/peeph.def
7827 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7831 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7832 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7833 if the left or right operand symbols have the accuse flag set.
7835 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7837 Changed the type of the result of the ! (NOT) operator to char;
7838 previously it returned the same type as the source. This allows
7839 us to eliminate all the genFloatNot functions (all of its target
7840 implementations were very buggy) since !float can use the same
7843 * src/SDCCicode.c (ast2iCode): ! returns char

7852 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7853 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7854 during interrupts. Ensure WSAVE is located at a shared bank address.
7855 2. Fixed page selection in some places
7856 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7857 the registers name strings.
7858 4. Fixed "signed / unsigned compare" compiler warnings.
7859 5. The PIC port manages its own allocation of the general purpose
7860 registers, but makes no attempt to reuse them. As a result when
7861 compiling it soon runs out of general purpose registers. Some
7862 additional code was added to the files pcode.c and device.c to walk
7863 through the function call tree and rename the registers so that they
7873 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7874 genPlus() & genMinus() when the result is the same as left or right
7876 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7880 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7882 Made bitfield a distinct type from bit so that bitfields
7883 convert as per ANSI C and bits retain their traditional
7884 boolean style behaviour. Implemented bitfield support in
7892 * src/ds390/gen.c: bit v bitfield split
7893 * src/z80/gen.c: New support for bitfields
7894 * support/regression/tests/bitfields.c: reenabled z80,
7897 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7899 Rules 246.x, 247.x relate to bitfields, the others speed up
7900 access to xdata mapped I/O devices.
7902 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7904 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7906 Cleaned up genPackBits and genUnpackBits and added two helper
7907 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7908 for literal assignments in genPackBits (thanks to Frieder for
7914 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7916 Fixed bug #748310 (pointer to function type mishandled when the
7917 function name is omitted). Also fixed a SIGSEGV when a function
7918 attribute (reentrant, etc) is used on a non-function or on a
7919 function but misplaced before the parameter list.
7921 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7923 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7924 * support/Util/SDCCerr.h,
7925 * support/Util/SDCCerr.c: Added func attr misuse error msg
7927 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7929 Fixed bug #787649 by anonymous
7930 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

7946 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7948 Made the constant following the "interrupt" keyword optional. If
7949 omitted, the function will not automatically be given an entry
7950 in the interrupt vector table (similar to #pragma NOIV, but
7951 less syntacticly kludgy). The interrupt number is also now
7952 range checked. Also fixed a bug in the high order bit example

7966 * src/SDCCicode.c (operandOperation): rewritten some ops
7967 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7968 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7970 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7971 be re-activated by defining REDUCE_LITERALS)
7972 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7973 unsigned, but are signed by default
7974 * src/SDCCval.c (constVal): rearranged
7975 * src/SDCCval.c (valMod): preliminary fix
7976 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8018 constants are unsigned; added recognition of "u" flag for unsigned
8019 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8020 * src/SDCCval.c (valDiv, valMod): fixed signdness
8021 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8022 signedness of modulo, left and right shift

8482 added if/endif conditional macros to remove options help
8483 messages from optionsTable when a port is not configured, added
8484 support for the PIc16 port in the ports table, when executing
8485 the compiler with no port specified on command line, a default
8486 port is selected with the new macro DEFAULT_PORT which is
8487 defined in port.h, in setDefaultOptions() linkOptions is removed
8488 from initialization assignment, since now it is a set,
8489 parseCmdLine uses setParseWithComma for linkOptions, in
8490 linkEdit() linkOptions are accessed with new function indexSet()
8491 which returns the i'th item of a set variable. See SDCCset.c, in
8492 linkEdit() when calling buildCmdLine(), added linkOptions as
8493 last argument. Now users can pass arguments to gplink via the
8494 -Wl option, main() uses pic16glue() to glue up pic16 programs

8508 gpasm complaining and test the linkage with gplink, _linkCmd and
8509 _asmCmd changed to be more gplink and gpasm friendly
8510 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8511 produced an error when parsed, peep rule 12 is added to utilize
8512 movff, but it is commented out since the pCode does not support
8513 yet a command with 2 address arguments
8515 2003-05-18 <johan AT balder>
8517 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8544 2003-05-11 Borut Razem <borut.razem AT siol.net>
8546 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9532 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9533 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9535 2003-01-07 <johan AT balder>
9537 * src/SDCCast.c (decorateType): fixed bug #600035
9539 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9540 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9550 2003-01-06 <johan AT balder>
9552 * src/SDCCicode.c: fixed array add
9554 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9555 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9556 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9558 2003-01-04 <johan AT balder>
9560 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9562 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9563 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9565 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9566 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9567 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9569 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9570 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9572 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9573 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9575 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9576 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9578 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9580 * in \sdcc\as\mcs51\ changed these files in order to create an
9581 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9582 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9583 following files to include the previous two files: aslink.dsp,
9584 Makefile.aslink, Makefile.bcc, and Makefile.in.
9586 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9587 .adb instead of .cdb
9589 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9591 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9592 value from option --iram-size.
9594 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9596 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9599 2002-09-18 <wiml AT hhhh.org>
9601 * SDCClrange.h: exposed setFromRange() and setToRange()
9602 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9603 packRegsForAccUse() (bug 542397)
9604 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9605 multiple times and emitting the fetch operations more than once
9606 added aopGetUsesAcc() function to allow binary operators to
9607 fetch their operands in the correct order; made genMinus() emit
9608 compact code for X = LITERAL - Y
9610 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9611 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9612 sprintf() in line 1267.
9614 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9615 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9618 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9619 Changes to aslink (All the changes are marked with 'JCF'):
9621 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9624 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9625 area BSEG. Also moves, if possible, the DATA area down into the internal
9626 ram so more space is available.
9628 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9631 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9632 not bytes. Function summary() which creates a memory usage summary
9633 file with extension .mem. Reports of overlaping stack and small stack
9634 size. If the space for the stack is less than 16 bytes aslink trows a
9637 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9638 the 8051. Option 'y' for memory summary output file.
9640 Changes to sdcc (All the changes are marked with 'JCF'):
9642 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9644 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9645 overlaying area for it (uses RegBankUsed[4]).
9647 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9648 bank zero as used by default. By default aslink locates the stack
9649 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9650 the creation of the .mem file. Delegates the allocation of data area
9651 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9652 the begining of the stack area to aslink.
9654 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9655 glue() in SDCCglue.c creates an area for it.
9657 2002-09-03 Borut Razem <borut.razem AT siol.net>
9658 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9659 sdcc/src/pic/glue.c:
9660 introduced atexit() handler for teporay files removal in case of
9661 errors, assertions, ...
9663 2002-08-29 Borut Razem <borut.razem AT siol.net>
9664 * sdcc/support/cpp2/auto-host_vc_in.h:
9665 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9666 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9667 Maybe there is a similar problem with BORLANDC? It should be checked!
9669 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9670 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9671 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9672 was not executed, and the compiler (cl) launched a warning:
9673 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9675 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9676 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9678 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9679 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9681 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9682 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9683 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9684 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9685 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9686 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9687 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9688 - added Release configuration in VS projects
9689 - review of compiler an linker options
9690 - VC .exe files are generated in bin_vc directory, not to interfere
9691 with binaries generated from other projects (cygwin, mingw, bcc ...)
9693 * sdcc/src/yacc.dsp: added
9695 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9696 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9697 and insert the version number definitions from .version
9699 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9701 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9702 added - genarate auto-host.h using auto-host_vc_in.h as template
9705 removed from CVS, generated automatically
9707 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9708 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9710 2002-08-11 Borut Razem <borut.razem AT siol.net>
9711 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9713 2002-08-10 Borut Razem <borut.razem AT siol.net>
9714 * src/SDCCmain.c (main):
9715 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9716 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9717 The consequence was that some temporary files were not removed.
9720 unification of code in functions tempfilename() and tempfile():
9721 function tempnam() is defined in Visual Studio 6.0 and .NET
9723 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9725 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9726 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9727 - removed compiler command line option /WX: Treats all warnings as errors
9728 - update a list of source files, included into the project
9730 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9731 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9732 changed project type to Generic Project so that can be correcly converted to VS.NET project
9734 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9736 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9738 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9740 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9741 added return 0 statements after assert() to make compiler happy
9743 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9744 added newline in the def file to keep MSC compiler satisfied
9746 * sdcc/src/z80/gen.c:
9747 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9748 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9749 - solved MSC error in function aopDump()
9751 * sdcc_vc.h: define PREFIX as "\\sdcc"
9753 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9754 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9793 2002-03-28 Johan Knol <johan AT balder>
9795 * src/SDCCval.c: fixed bug #532436
9797 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9799 Added "char *Processor" field to the port structure.
9802 Added -p option. Allows port dependent processor to be specified.
9805 Initialized the new field char *Processor field to NULL in all ports
9808 Compiler generated registers for interrupt context saving
9809 were not getting allocated.
9811 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9814 Fixed left shift. Will promote the left side of a left shift
9815 if a) left shifting more than size of operand or b) when assigned
9816 to something size > size of left side
9818 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9820 tons of changes. Register allocation has been
9821 rewritten. Added customization for the various PICs. Flow
9822 analysis is restructured. ...
9828 Added. device.c is a PIC port hack to accomodate variations
9831 2002-03-13 Michael Hope <michaelh AT vroom>
9833 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9835 2002-03-04 johanknol <johanknol AT manik>
9837 * /src/SDCCval.c: fixed
9839 const unsigned char arr[][2] = { { 0, 1 } };

9842 2002-03-04 bela <bela AT manik>
9844 * /device/include/mcs51reg.h:
9845 ds89c420 register definition update
9847 2002-03-03 <johan AT FRIJA>

9926 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9928 * sdcc/src/SDCCloop.c:
9929 Previous fix was not good. basic blocks that have "break" or "return" are
9930 not really partof a loop , but live ranges used in these blocks should
9931 be live thru the entire loop, so set partOfLoop but don't add them to
9934 2002-02-21 <johan AT FRIJA>
9936 * src/SDCCcse.c: fixed bug #514308
9938 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9941 Fixed BUG #519583. If a conditional block ended in a return/break
9942 statement inside a loop, it was not being considered part of the loop.
9944 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9946 2002-02-10 Karl Bongers <karl AT turbobit.com>
9949 Fixed up SDCDB debugger somewhat. Updated debugger/README
9950 with lots of comments and notes.
9952 * device/examples/test2.c:
9953 Fix bug, "red" variable not being initialized(compiler complained).
9955 * device/examples/Makefile, examples/test3.c:
9956 Add Makefile in device/examples folder, compiles test3.c
9957 for use as a multiple module SDCDB test case.
9959 * sim/ucsim/cmd.src/cmdset.cc:
9960 Took out debug printfs in ucsim "next" command.
9963 Karl and Johan start ucsim XA support. Most dissassembly working,
9964 about 75% emulation done(plenty of work remaining).
9966 * sim/ucsim/z80.src:
9967 Add Z80 support to ucsim, add test-ucz80 regression test,
9968 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9969 Notice z80 compiler fails on examples/test3.c/crc code.
9971 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9973 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

9983 3) added __builtin_swapw swap bytes of a short
9985 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9986 1) handle multiple send & receives from register bank1
9987 2) ralloc can now allocate DPTR1 to some liveRanges
9989 * src/SDCCsymt.c, src/SDCCsymt.h:
9990 changes to handle multiple sends & receives
9993 added some pointer arithmetic optimization
9996 added some pointer arithmetic optimizations but not stable yet so not
9997 called from anywhere (will get this working shortly)
9999 * src/SDCCopt.c: fixed for multiple sends & receives
10002 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10003 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10004 set preprocessor defines (depending on options)
10006 * src/SDCCicode.c, src/SDCCicode.h:
10007 changes made to handle multiple sends & receives
10010 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
