3 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
4 submitted by the Debian SDCC maintainer Aurelien Jarno:
5 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
6 archive with gcc 4.1 on mips and wrote the patch"
8 2006-03-16 Raphael Neider <rneider AT web.de>
10 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
11 the left operand is shorter than the result (c* = lit-c* + int),
13 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
16 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
18 * src/.version: increased version number to 2.5.5
19 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
20 linking is done manually in pic16 port's _linkEdit,
21 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
22 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
23 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
24 allocate asmop as AOP_ACC,
25 (aopForRemat): added parameter 'bool result' in function declaration,
26 (pic16_aopGet): return AOP_ACC when accessing WREG,
27 (pic16_popGetTempReg): minor modification,
28 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
30 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
31 calling function in absolute addresses,
32 (genAssign): take into account AOP_ACC asmop,
33 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
34 * src/pic16/pcoderegs.c: some debug functions and lines added,
35 * src/pic16/ralloc.c (decodeRegType): added but commented out,
36 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
38 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
39 call to allocReg, not by manually allocating a new one,
40 (pic16_assignRegisters): now before going through the register
41 allocating functions mark all registers as free. This eliminates some
42 side effects resulting from peephole parser done earlier in the backbone
44 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

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

92 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
94 2006-03-06 Borut Razem <borut.razem AT siol.net>
96 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
99 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

104 the number of the local variables used by the specified function, added
105 'xinst' for initial support for Extended Instruction Support,
106 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
107 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
108 port->fun_prefix anymore (may change later),
109 (genFunction, genEndFunction): do not store/restore local registers for
110 _main (this should take care the --main-return command line option in
112 (genOr): removed some legacy pic-port instructions,
113 * src/pic16/genarith.c (genAddLit): re-enabled old code because
114 performing operations with SFR's causes data to be written more than
115 once to each SFR. Perhaps SFRs should be handled in special cases...
116 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
118 * src/pic16/main.c (_process_pragma): stack bound checking did not take
119 into account for stack starting position,
120 (struct OPTIONS pic16_optionsTable): added command line argument
121 --extended or -y for Extended Instruction Support,
122 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
123 (deassignLRs): *** perhaps the most important change, old 'for' code
124 (commented out for reference), didn't account for some registers which
125 were left marked 'not free' after a pointer operation. The change
126 reduces register usage a lot in some cases

2401 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2402 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2403 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2404 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2405 always available in leading double underscore form. The C99 support is

2484 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2486 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2488 * device/lib/printf_large.c: removed inline assembly for portability and
2489 readability. Use printf_fast if speed or size are more important.
2490 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2491 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2493 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2495 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2496 prevent compiler warning
2498 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2500 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2501 moved to level 0 and declared as static. Also they are explicit
2502 placed in access bank. This was necessery because some times they
2503 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2504 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2505 optimizations. Currently only compare to unsigned char is implemented,
2506 * src/pic16/gen.c: added fReturnIdx array,
2507 * (struct resolvedIfx) is moved to gen.h and made public,
2508 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2509 * (aopForSym): added an optimization to directly store in stack of
2510 the operand of a SEND iCode,
2511 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2512 but as registers instead (AOP_REG) using the fReturnIdx array,
2513 * (pic16_freeAsmop): remove the freed register from the
2514 _G.sregsAlloc field,
2515 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2516 a compare of 'WREG',
2517 * (pic16_popGetTempRegCond): changed function prototype, now
2518 function takes also a bitVector argument v which holds the current
2519 set of registers that are allocated for stack access by aopForSym,
2520 registers allocated in aopForSym for accessing stack symbols are not
2521 any more part of the functions usedRegs field,
2522 * (genCall): some times aopOp is called for a stack variable to be
2523 send, aopForSym might perform the push, if this is true make sure
2524 that genCall doesn't push the variable twice by testing _G.resDirect,
2525 * (genFunction): changed testing for unspecified interrupt number
2526 from 256 to INTNO_UNSPEC,
2527 * modified selection scheme of frame pointer generation. Previously
2528 if function did use local registers a frame pointer was generated,
2529 now a frame pointer is generated only if function has arguments
2530 (that need PLUSW2 register access), or has stack arguments, or the
2531 compiler is not instructed to omit the frame pointer,
2532 * (genEndFunction): before restoring local registers that were saved
2533 in the function preamble, also restore the registers that *might*
2534 have been allocated for stack access,
2535 * (genRet): removed some old comments,
2536 * (genCmp, the active (RN's) version): added a call to the
2537 pic16_genCmp_special function to perform the compare with a more
2538 robust and optimized way,
2539 * (genInline): a feature has been added in inline code generation,
2540 which allows a wildcard variable substitution when writing inline
2541 assembly. Code is incomplete and experimental therefore undocumented,
2542 * (genCast): changed order of aopOp for result and right to allow
2543 aopForSym to directly load the result if possible,
2544 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2545 perform an optimized compare on some selected special occasions,
2546 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2547 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2548 generate an IVT any more,
2549 * src/pic16/main.c (pic16_optionsTable): added command line option
2551 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2552 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2554 * src/pic16/NOTES: Raphael Neider added in list of active developers
2555 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2556 jumptable_end to prevent bug #,
2557 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2558 inCond and outCond fields,
2559 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2560 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2561 turn off register spilling,
2562 * (packRegsForOneUse): synced with other ports' versions although it
2563 is not used currently,
2564 * (pic16_packRegisters): added an optimization while reading
2565 structure bitfields, some registers may be saved (malloc code is
2566 decreased by 80 bytes)
2568 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2570 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2571 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2572 this can be optimized more?
2574 2005-03-10 Raphael Neider <rneider AT web.de>
2576 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2577 genNearPointerGet): (hopefully) fixed access to bitfields via
2578 pointers (p->bitN = x; and x = p->bitN; failed)
2580 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2582 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3212 Adding support for replacing ljmps with sjmps in jumptables
3213 generated for switch statements. For now you need to set the
3214 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3215 Now 4 algorithms for mcs51 jumptable generation are used:
3216 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3217 addresses loaded pc-relative for up to 112 cases and stack-pushing
3218 target addresses loaded with offset from dptr for up to 256 cases.

3248 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3250 * added libc directory. The current version of LibC contains string
3251 functions, ctype functions and macros and some functions of the
3252 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3253 be extensively tested in the future. Standard disclaimer here.
3254 Library is not automatically build yet. But one can build it by
3255 invoking 'make' inside the libc directory.

3265 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3266 * (pic16_storeForReturn): optimized return of 0,
3267 * (genCmp): experimental code for new genCmp which uses PIC18's
3268 special compare&skip instructions. Initial tests fail some times
3269 with variables grater than 1 byte in size, so new code is disabled,
3270 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3272 * (genCast): began a fix to optimize the casting of a bit to another
3273 bit, now assigning a bitfield to another bitfield will fail, sorry,
3274 * src/pic16/main.c: disabled the use of lr-support feature,
3275 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3282 and 1 for banking instruction,
3283 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3284 caused stop processing pCodes after a inline assembly block,
3285 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3286 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3287 registers when it shouldn't,
3288 * src/pic16/ralloc.c (allocReg): add preliminary support for
3289 supporting a limited set of temporary registers,
3291 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3297 (genFunction): optimize RECEIVE iCodes in reentrant functions
3299 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6299 loaded with the linker search paths (-L arguments) and the libraries
6300 to be linked with the current source (-l arguments). Changes
6301 currently will affect only the pic16 port.
6302 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6303 include path the port specific paths and port specific libraries,
6304 * gplink command now contains the $3 argument,
6305 * src/pic16/device.h,

6322 Documenting changes from previous commits.
6323 * configure.in (version 1.56),
6324 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6325 when generating output files to configure the pic16 library,
6326 but now I've commented it out, since gputils aren't installed in the
6327 SF compile farm, so library won't compile
6329 * device/lib/Makefile.in (version 1.56): initially I've added in
6330 target 'all' the prerequestive 'model-pic16' so it compiled the
6331 pic16 library, but now I've commented it out for the same reasons
6333 * added targets 'model-pic16' and 'objects-pic16' to compile the
6335 * added target 'port-specific-objects-pic16' to handle the
6336 generated libraries and copy them into the build/ directory
6337 * added target 'clean-intermediate-pic16' to clean intermediate
6338 files into pic16 directory
6339 * in target 'installdirs' added line to create directory pic16 in

6343 added lines to copy all header files to installation path,
6344 * in target 'installdirs' added line create directory for pic16
6345 headers in the installation path

6593 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6595 A python script to validate compiler diagnostic messages. It can be
6596 used to verify that sdcc complains about bad c source code and
6597 gives a good location of the error.
6598 * support/valdiag/Makefile,
6599 * support/valdiag/valdiag.py,
6600 * support/valdiag/tests/*
6602 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6604 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6605 * src/SDCCsymt.c (newEnumType),
6607 * support/Util/SDCCerr.c,
6608 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6610 * support/regression/tests/enum.c: added test for enum values that
6611 require at least 2 bytes of storage.
6613 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6615 * src/common.h: added ifndef/define/endif macros
6616 around the header file.
6617 Bug reported from Jesus Calvino-Fraga
6619 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6621 * sdcc.spec: updated
6622 * device/include/Makefile.in: don't install CVS directories
6623 * device/lib/Makefile.in: added removal of CVS directories after install
6624 * doc/Makefile: fixed install, added local_icons
6625 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6626 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6627 * src/ds390/gen.c (genRightShift): fixed bug #870788
6628 * src/SDCCast.c (decorateType): fixed bug #870781
6630 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6632 PIC16 port related changes:
6633 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6634 added variable stackPos,
6636 * gen.c: genCall, assignResultValue: added support for
6637 pushing/retrieving function parameters to/from stack,
6638 genFunction,genEndFunction: setup stack frame for the
6640 genAddrOf: will be changed according to bug 863624
6642 * added files genutils.c and genutils.h which contain gen*
6643 debugged and optimised functions extracted from gen.c
6645 * glue.c: added variable 'externs' which holds extern symbols,
6646 pic16emitRegularMap: is modified to properly handle relocatable
6647 symbols under the new scheme,
6648 pic16createInterruptVect: is modified
6649 pic16printPublics: is modified to emit 'global' assembler directives,
6650 added pic16_printExterns to print extern symbols,
6651 pic16glue: initializes stack/frame pointer in the beginning of
6652 the assembly output. Temporary hack, will be corrected later,
6653 because gplink yet does not support stack and SDCC does not
6654 yet support a type of crt0.o object to create the final binary.
6656 * Removed many lines that contain 8051 legacy code.
6657 * The code is finally placed under a 'code' directive.
6658 * Added port specific options.
6660 * _process_pragma: simplified since now we do not need *special*
6661 include file to define SFR registers. But a separate header
6662 will be needed. This will be developed later.
6663 * _pic16_parseOptions: added, parses port specific options:
6664 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6665 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6666 --preplace-udata-with=
6668 * _pic16_setDefaultOptions: modified to initialize section names,
6669 but hack is temporarly out of order since it needs improvement.
6670 * _pic16_genAssemblerPreamble: configuration words are emitted by
6671 their address instead of their name. This part is incomplete and
6672 supports only the 18Fxx2 devices. Other devices will emit an error
6673 during assembly since they do not contain the same set of config
6675 * _pic16_genIVT: is modified,
6677 * pcode.c: added definitions for some hardware registers that are needed
6679 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6680 All PCI entries are updated. Now LFSR is supported.
6681 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6682 * added pic16_newpCodeOpLit2 to support instructions with
6683 two literal arguments
6684 * pic16_pCode2str: corrected code that emits assembler instructions
6685 with two literal operands and those that have an access bit modifier
6686 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6687 this fixes a bug which caused some labels to be lost, when an
6688 assembler directive was added, i.e. banksel,
6689 * pic16_FixRegisterBanking: improved logic that causes the insertion
6691 * InlineFunction: functions that are called once, are not any more
6692 inlined. This can be a port option in the future,
6694 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6696 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6697 hold the corresponding uninitialized symbols,
6698 * pic16_allocProcessorRegister: registers have explicit marked the
6700 * pic16_allocInternalRegister: registers are explicit marked as
6702 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6703 processing list, so bit registers were lost,
6706 * ralloc.h: added field 'accessBank' and original symbol operand
6707 in register definition,
6708 * removed the field isMapped from register definition,
6710 ** Several functions have been removed from various sources:
6711 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6712 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6713 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6714 pic16_assignRelocatableRegisters
6716 ** others have been introduced:
6717 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6718 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6720 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6722 * support/scripts/inc2h.pl: changed definition of BIT_AT
6723 to emit 'sbit at' instead of 'bit at'. This was a request.
6725 PIC16 port related preliminary changes:
6726 * gen.c: prefixed function popRegFromString with
6727 pic16_ and all references to it corrected
6728 * pcode.c: all pic16_pc_* hardware registers prefixed
6729 with underscore (_),
6730 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6731 * ralloc.c: newReg(): when register is REG_SFR then
6732 set address to rIdx,
6733 pic16_allocProcessorRegister(): marks register wasUsed=0
6734 pic16_writeUsedRegs(): added a call to assign processor
6735 registers via pic16_assignFixedRegisters
6737 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6739 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6740 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6741 variables in unused register banks. Also the SSEG is placed
6742 wherever there is enough space for it, and IDATA can be anywhere
6743 in internal RAM. For now compile using -Wl-Y[stack_size].
6744 The mem file is different for this option as well, since it
6745 makes no sense of talking about DSEG lenght.
6747 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6749 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6750 in certain cases, e.g. when ROM assignment, patch provided
6751 from Albert den Haan.
6753 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6896 * src/mcs51/peephole.def,
6897 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6992 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6994 * src/SDCCast.c (decorateType): disabled a transformation I added in
6995 revision 1.188 (access to fields of a structure at an absolute address);
6996 it breaks with bitfields, extern declarations, and gcse analysis.
6997 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6998 could be assigned through a pointer, so don't complain.
6999 * src/SDCCast.c (astErrors),
7001 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7638 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7639 support for standard C idiom of memory mapped variables; for
7640 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7641 to xdata int at 0x1234 tempvar = 1.
7642 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7643 provided by Akiya ISHIDA

7659 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7661 Fixed bug #621531 (const & volatile confusion in the type chain).
7662 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7663 refer to the const or volatile state of the pointer itself.

7754 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7755 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7756 fetching of the pointer
7757 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7758 copied from genNearPointerSet()
7759 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7760 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7761 If they pop r0/r1 they must be called in the opposite order than aopOp().
7762 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7763 (resp. --stack-auto), prepared for --xstack

7774 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7776 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7777 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7778 type for bits was changed. It resulted in bit variables becoming
7779 global, which is not permitted in PIC 14 assembly output.
7781 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7783 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7796 A few small changes that speed up the peephole optimizer.
7800 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7802 Try to make the peephole optimizer smarter by maintaining
7803 an association between the assembly source code and the
7804 iCodes that originated them. Put this information to use
7805 with a new peephole rule condition "notVolatile" so that
7806 the rules can be aggressive yet still safe.
7811 * src/mcs51/peeph.def
7813 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7817 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7818 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7819 if the left or right operand symbols have the accuse flag set.
7821 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7823 Changed the type of the result of the ! (NOT) operator to char;
7824 previously it returned the same type as the source. This allows
7825 us to eliminate all the genFloatNot functions (all of its target
7826 implementations were very buggy) since !float can use the same

7838 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7839 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7840 during interrupts. Ensure WSAVE is located at a shared bank address.
7841 2. Fixed page selection in some places
7842 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7843 the registers name strings.
7844 4. Fixed "signed / unsigned compare" compiler warnings.
7845 5. The PIC port manages its own allocation of the general purpose
7846 registers, but makes no attempt to reuse them. As a result when
7847 compiling it soon runs out of general purpose registers. Some
7848 additional code was added to the files pcode.c and device.c to walk
7849 through the function call tree and rename the registers so that they
7859 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7860 genPlus() & genMinus() when the result is the same as left or right

7866 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7868 Made bitfield a distinct type from bit so that bitfields
7869 convert as per ANSI C and bits retain their traditional
7870 boolean style behaviour. Implemented bitfield support in
7878 * src/ds390/gen.c: bit v bitfield split
7879 * src/z80/gen.c: New support for bitfields
7880 * support/regression/tests/bitfields.c: reenabled z80,
7883 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7885 Rules 246.x, 247.x relate to bitfields, the others speed up
7886 access to xdata mapped I/O devices.
7888 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7890 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7892 Cleaned up genPackBits and genUnpackBits and added two helper
7893 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7894 for literal assignments in genPackBits (thanks to Frieder for
7900 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7902 Fixed bug #748310 (pointer to function type mishandled when the
7903 function name is omitted). Also fixed a SIGSEGV when a function
7904 attribute (reentrant, etc) is used on a non-function or on a
7905 function but misplaced before the parameter list.
7907 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7909 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7910 * support/Util/SDCCerr.h,
7911 * support/Util/SDCCerr.c: Added func attr misuse error msg

7932 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7934 Made the constant following the "interrupt" keyword optional. If
7935 omitted, the function will not automatically be given an entry
7936 in the interrupt vector table (similar to #pragma NOIV, but
7937 less syntacticly kludgy). The interrupt number is also now
7938 range checked. Also fixed a bug in the high order bit example

7951 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
7952 * src/SDCCicode.c (operandOperation): rewritten some ops
7953 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7954 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7956 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7957 be re-activated by defining REDUCE_LITERALS)
7958 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7959 unsigned, but are signed by default
7960 * src/SDCCval.c (constVal): rearranged
7961 * src/SDCCval.c (valMod): preliminary fix
7962 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8005 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8006 * src/SDCCval.c (valDiv, valMod): fixed signdness
8007 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8008 signedness of modulo, left and right shift

8467 * src/SDCCmain.c: linkOptions is changed to set *,
8468 added if/endif conditional macros to remove options help
8469 messages from optionsTable when a port is not configured, added
8470 support for the PIc16 port in the ports table, when executing
8471 the compiler with no port specified on command line, a default
8472 port is selected with the new macro DEFAULT_PORT which is
8473 defined in port.h, in setDefaultOptions() linkOptions is removed
8474 from initialization assignment, since now it is a set,
8475 parseCmdLine uses setParseWithComma for linkOptions, in
8476 linkEdit() linkOptions are accessed with new function indexSet()
8477 which returns the i'th item of a set variable. See SDCCset.c, in
8478 linkEdit() when calling buildCmdLine(), added linkOptions as
8479 last argument. Now users can pass arguments to gplink via the
8480 -Wl option, main() uses pic16glue() to glue up pic16 programs

8494 gpasm complaining and test the linkage with gplink, _linkCmd and
8495 _asmCmd changed to be more gplink and gpasm friendly
8496 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8497 produced an error when parsed, peep rule 12 is added to utilize
8498 movff, but it is commented out since the pCode does not support
8499 yet a command with 2 address arguments
8501 2003-05-18 <johan AT balder>
8503 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8530 2003-05-11 Borut Razem <borut.razem AT siol.net>
8532 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9523 * src/SDCCast.c (decorateType): fixed bug #600035
9525 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9526 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
9527 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
9528 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

9530 * src/pic/ralloc.c: outcommented unused variable to remove warnings
9532 2003-01-06 <karl AT turbobit.com>
9533 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
9536 2003-01-06 <johan AT balder>
9538 * src/SDCCicode.c: fixed array add
9540 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9541 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9542 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9544 2003-01-04 <johan AT balder>
9546 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9548 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9549 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9551 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9552 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9553 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9555 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9556 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9558 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9559 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9561 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9562 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9564 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9566 * in \sdcc\as\mcs51\ changed these files in order to create an
9567 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9568 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9569 following files to include the previous two files: aslink.dsp,
9570 Makefile.aslink, Makefile.bcc, and Makefile.in.
9572 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9573 .adb instead of .cdb
9575 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9577 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9578 value from option --iram-size.
9580 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9582 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9585 2002-09-18 <wiml AT hhhh.org>
9587 * SDCClrange.h: exposed setFromRange() and setToRange()
9588 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9589 packRegsForAccUse() (bug 542397)
9590 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9591 multiple times and emitting the fetch operations more than once
9592 added aopGetUsesAcc() function to allow binary operators to
9593 fetch their operands in the correct order; made genMinus() emit
9594 compact code for X = LITERAL - Y
9596 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9597 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9598 sprintf() in line 1267.
9600 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9601 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9604 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9605 Changes to aslink (All the changes are marked with 'JCF'):
9607 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9610 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9611 area BSEG. Also moves, if possible, the DATA area down into the internal
9612 ram so more space is available.
9614 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9617 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9618 not bytes. Function summary() which creates a memory usage summary
9619 file with extension .mem. Reports of overlaping stack and small stack
9620 size. If the space for the stack is less than 16 bytes aslink trows a
9623 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9624 the 8051. Option 'y' for memory summary output file.
9626 Changes to sdcc (All the changes are marked with 'JCF'):
9628 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9630 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9631 overlaying area for it (uses RegBankUsed[4]).
9633 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9634 bank zero as used by default. By default aslink locates the stack
9635 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9636 the creation of the .mem file. Delegates the allocation of data area
9637 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9638 the begining of the stack area to aslink.
9640 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9641 glue() in SDCCglue.c creates an area for it.
9643 2002-09-03 Borut Razem <borut.razem AT siol.net>
9644 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9645 sdcc/src/pic/glue.c:
9646 introduced atexit() handler for teporay files removal in case of
9647 errors, assertions, ...
9649 2002-08-29 Borut Razem <borut.razem AT siol.net>
9650 * sdcc/support/cpp2/auto-host_vc_in.h:
9651 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9652 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9653 Maybe there is a similar problem with BORLANDC? It should be checked!
9655 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9656 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9657 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9658 was not executed, and the compiler (cl) launched a warning:
9659 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9661 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9662 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9664 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9665 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9667 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9668 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9669 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9670 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9671 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9672 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9673 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9674 - added Release configuration in VS projects
9675 - review of compiler an linker options
9676 - VC .exe files are generated in bin_vc directory, not to interfere
9677 with binaries generated from other projects (cygwin, mingw, bcc ...)
9679 * sdcc/src/yacc.dsp: added
9681 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9682 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9683 and insert the version number definitions from .version
9685 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9687 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9688 added - genarate auto-host.h using auto-host_vc_in.h as template
9691 removed from CVS, generated automatically
9693 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9694 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9696 2002-08-11 Borut Razem <borut.razem AT siol.net>
9697 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9699 2002-08-10 Borut Razem <borut.razem AT siol.net>
9700 * src/SDCCmain.c (main):
9701 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9702 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9703 The consequence was that some temporary files were not removed.
9706 unification of code in functions tempfilename() and tempfile():
9707 function tempnam() is defined in Visual Studio 6.0 and .NET
9709 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9711 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9712 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9713 - removed compiler command line option /WX: Treats all warnings as errors
9714 - update a list of source files, included into the project
9716 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9717 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9718 changed project type to Generic Project so that can be correcly converted to VS.NET project
9720 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9722 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9724 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9726 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9727 added return 0 statements after assert() to make compiler happy
9729 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9730 added newline in the def file to keep MSC compiler satisfied
9732 * sdcc/src/z80/gen.c:
9733 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9734 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9735 - solved MSC error in function aopDump()
9737 * sdcc_vc.h: define PREFIX as "\\sdcc"
9739 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9740 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9743 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9744 - Rewrote the register banking algorithm.
9745 - Added pCode live-range analysis to registers (for now, only non-used and
9746 singly-used registers optimized away)
9748 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9750 * 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.

9775 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9777 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9779 2002-03-28 Johan Knol <johan AT balder>
9781 * src/SDCCval.c: fixed bug #532436
9783 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9785 Added "char *Processor" field to the port structure.
9788 Added -p option. Allows port dependent processor to be specified.
9791 Initialized the new field char *Processor field to NULL in all ports
9794 Compiler generated registers for interrupt context saving
9795 were not getting allocated.
9797 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9800 Fixed left shift. Will promote the left side of a left shift
9801 if a) left shifting more than size of operand or b) when assigned
9802 to something size > size of left side
9804 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9806 tons of changes. Register allocation has been
9807 rewritten. Added customization for the various PICs. Flow
9808 analysis is restructured. ...
9814 Added. device.c is a PIC port hack to accomodate variations
9817 2002-03-13 Michael Hope <michaelh AT vroom>
9819 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9821 2002-03-04 johanknol <johanknol AT manik>
9823 * /src/SDCCval.c: fixed
9825 const unsigned char arr[][2] = { { 0, 1 } };
9826 t18.c:1: error: Initializer element is not constant
9828 2002-03-04 bela <bela AT manik>
9830 * /device/include/mcs51reg.h:
9831 ds89c420 register definition update
9833 2002-03-03 <johan AT FRIJA>

9912 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9914 * sdcc/src/SDCCloop.c:
9915 Previous fix was not good. basic blocks that have "break" or "return" are
9916 not really partof a loop , but live ranges used in these blocks should
9917 be live thru the entire loop, so set partOfLoop but don't add them to
9920 2002-02-21 <johan AT FRIJA>
9922 * src/SDCCcse.c: fixed bug #514308
9924 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9927 Fixed BUG #519583. If a conditional block ended in a return/break
9928 statement inside a loop, it was not being considered part of the loop.
9930 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9932 2002-02-10 Karl Bongers <karl AT turbobit.com>
9935 Fixed up SDCDB debugger somewhat. Updated debugger/README
9936 with lots of comments and notes.
9938 * device/examples/test2.c:
9939 Fix bug, "red" variable not being initialized(compiler complained).
9941 * device/examples/Makefile, examples/test3.c:
9942 Add Makefile in device/examples folder, compiles test3.c
9943 for use as a multiple module SDCDB test case.
9945 * sim/ucsim/cmd.src/cmdset.cc:
9946 Took out debug printfs in ucsim "next" command.
9949 Karl and Johan start ucsim XA support. Most dissassembly working,
9950 about 75% emulation done(plenty of work remaining).
9952 * sim/ucsim/z80.src:
9953 Add Z80 support to ucsim, add test-ucz80 regression test,
9954 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9955 Notice z80 compiler fails on examples/test3.c/crc code.
9957 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

9967 from a memory mapped port
9968 2) added __builtin_memcmp
9969 3) added __builtin_swapw swap bytes of a short
9971 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9972 1) handle multiple send & receives from register bank1
9973 2) ralloc can now allocate DPTR1 to some liveRanges
9975 * src/SDCCsymt.c, src/SDCCsymt.h:
9976 changes to handle multiple sends & receives
9979 added some pointer arithmetic optimization
9982 added some pointer arithmetic optimizations but not stable yet so not
9983 called from anywhere (will get this working shortly)
9985 * src/SDCCopt.c: fixed for multiple sends & receives
9988 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9989 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9990 set preprocessor defines (depending on options)
9992 * src/SDCCicode.c, src/SDCCicode.h:
9993 changes made to handle multiple sends & receives
9996 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
