3 * src/.version: increased version number to 2.5.5
4 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
5 linking is done manually in pic16 port's _linkEdit,
6 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
7 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
8 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
9 allocate asmop as AOP_ACC,
10 (aopForRemat): added parameter 'bool result' in function declaration,
11 (pic16_aopGet): return AOP_ACC when accessing WREG,
12 (pic16_popGetTempReg): minor modification,
13 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
15 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
16 calling function in absolute addresses,
17 (genAssign): take into account AOP_ACC asmop,
18 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
19 * src/pic16/pcoderegs.c: some debug functions and lines added,
20 * src/pic16/ralloc.c (decodeRegType): added but commented out,
21 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
23 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
24 call to allocReg, not by manually allocating a new one,
25 (pic16_assignRegisters): now before going through the register
26 allocating functions mark all registers as free. This eliminates some
27 side effects resulting from peephole parser done earlier in the backbone
29 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
31 * src/SDCCicode.c (geniCodeLogic),
32 * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

51 (aopForSym, aopOp): increment asmop.allocated if reused,
52 (freeAsmop): decrement asmop.allocated and check for zero instead of
54 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
55 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

79 2006-03-06 Borut Razem <borut.razem AT siol.net>
81 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,

87 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
88 which dumps before the function entry point a data byte which represents
89 the number of the local variables used by the specified function, added
90 'xinst' for initial support for Extended Instruction Support,
91 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
92 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
93 port->fun_prefix anymore (may change later),
94 (genFunction, genEndFunction): do not store/restore local registers for
95 _main (this should take care the --main-return command line option in
97 (genOr): removed some legacy pic-port instructions,
98 * src/pic16/genarith.c (genAddLit): re-enabled old code because
99 performing operations with SFR's causes data to be written more than
100 once to each SFR. Perhaps SFRs should be handled in special cases...
101 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
103 * src/pic16/main.c (_process_pragma): stack bound checking did not take
104 into account for stack starting position,
105 (struct OPTIONS pic16_optionsTable): added command line argument
106 --extended or -y for Extended Instruction Support,
107 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
108 (deassignLRs): *** perhaps the most important change, old 'for' code
109 (commented out for reference), didn't account for some registers which
110 were left marked 'not free' after a pointer operation. The change
111 reduces register usage a lot in some cases

2386 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2387 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2388 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2389 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2390 always available in leading double underscore form. The C99 support is
2391 mostly missing, but it's a start.
2392 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2393 reserved identifier "__data".
2395 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2469 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2471 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2473 * device/lib/printf_large.c: removed inline assembly for portability and
2474 readability. Use printf_fast if speed or size are more important.
2475 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2476 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2478 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2480 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2481 prevent compiler warning
2483 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2485 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2486 moved to level 0 and declared as static. Also they are explicit
2487 placed in access bank. This was necessery because some times they
2488 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2489 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2490 optimizations. Currently only compare to unsigned char is implemented,
2491 * src/pic16/gen.c: added fReturnIdx array,
2492 * (struct resolvedIfx) is moved to gen.h and made public,
2493 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2494 * (aopForSym): added an optimization to directly store in stack of
2495 the operand of a SEND iCode,
2496 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2497 but as registers instead (AOP_REG) using the fReturnIdx array,
2498 * (pic16_freeAsmop): remove the freed register from the
2499 _G.sregsAlloc field,
2500 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2501 a compare of 'WREG',
2502 * (pic16_popGetTempRegCond): changed function prototype, now
2503 function takes also a bitVector argument v which holds the current
2504 set of registers that are allocated for stack access by aopForSym,
2505 registers allocated in aopForSym for accessing stack symbols are not
2506 any more part of the functions usedRegs field,
2507 * (genCall): some times aopOp is called for a stack variable to be
2508 send, aopForSym might perform the push, if this is true make sure
2509 that genCall doesn't push the variable twice by testing _G.resDirect,
2510 * (genFunction): changed testing for unspecified interrupt number
2511 from 256 to INTNO_UNSPEC,
2512 * modified selection scheme of frame pointer generation. Previously
2513 if function did use local registers a frame pointer was generated,
2514 now a frame pointer is generated only if function has arguments
2515 (that need PLUSW2 register access), or has stack arguments, or the
2516 compiler is not instructed to omit the frame pointer,
2517 * (genEndFunction): before restoring local registers that were saved
2518 in the function preamble, also restore the registers that *might*
2519 have been allocated for stack access,
2520 * (genRet): removed some old comments,
2521 * (genCmp, the active (RN's) version): added a call to the
2522 pic16_genCmp_special function to perform the compare with a more
2523 robust and optimized way,
2524 * (genInline): a feature has been added in inline code generation,
2525 which allows a wildcard variable substitution when writing inline
2526 assembly. Code is incomplete and experimental therefore undocumented,
2527 * (genCast): changed order of aopOp for result and right to allow
2528 aopForSym to directly load the result if possible,
2529 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2530 perform an optimized compare on some selected special occasions,
2531 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2532 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2533 generate an IVT any more,
2534 * src/pic16/main.c (pic16_optionsTable): added command line option
2536 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2537 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2539 * src/pic16/NOTES: Raphael Neider added in list of active developers
2540 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2541 jumptable_end to prevent bug #,
2542 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2543 inCond and outCond fields,
2544 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2545 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2546 turn off register spilling,
2547 * (packRegsForOneUse): synced with other ports' versions although it
2548 is not used currently,
2549 * (pic16_packRegisters): added an optimization while reading
2550 structure bitfields, some registers may be saved (malloc code is
2551 decreased by 80 bytes)
2553 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2555 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2556 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2557 this can be optimized more?
2559 2005-03-10 Raphael Neider <rneider AT web.de>
2561 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2562 genNearPointerGet): (hopefully) fixed access to bitfields via
2563 pointers (p->bitN = x; and x = p->bitN; failed)
2565 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2567 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
2569 2005-03-09 Raphael Neider <rneider AT web.de>
2571 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
2573 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
2575 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
2576 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
2577 (regTypeNum): set REG_BIT type if necessary
2578 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

3197 Adding support for replacing ljmps with sjmps in jumptables
3198 generated for switch statements. For now you need to set the
3199 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3200 Now 4 algorithms for mcs51 jumptable generation are used:
3201 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3202 addresses loaded pc-relative for up to 112 cases and stack-pushing
3203 target addresses loaded with offset from dptr for up to 256 cases.

3233 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3235 * added libc directory. The current version of LibC contains string
3236 functions, ctype functions and macros and some functions of the
3237 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3238 be extensively tested in the future. Standard disclaimer here.
3239 Library is not automatically build yet. But one can build it by
3240 invoking 'make' inside the libc directory.

3250 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3251 * (pic16_storeForReturn): optimized return of 0,
3252 * (genCmp): experimental code for new genCmp which uses PIC18's
3253 special compare&skip instructions. Initial tests fail some times
3254 with variables grater than 1 byte in size, so new code is disabled,
3255 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3257 * (genCast): began a fix to optimize the casting of a bit to another
3258 bit, now assigning a bitfield to another bitfield will fail, sorry,
3259 * src/pic16/main.c: disabled the use of lr-support feature,
3260 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3266 * (isBankInstruction): modified to return 0 for no banking instruction,
3267 and 1 for banking instruction,
3268 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3269 caused stop processing pCodes after a inline assembly block,
3270 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3271 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3272 registers when it shouldn't,
3273 * src/pic16/ralloc.c (allocReg): add preliminary support for
3274 supporting a limited set of temporary registers,
3276 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3278 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3279 genDataPointerSet): ensure assignments always copy in MSB to LSB
3281 (loadRegFromAop): recognize CLRH optimization,
3282 (genFunction): optimize RECEIVE iCodes in reentrant functions
3284 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3286 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6284 loaded with the linker search paths (-L arguments) and the libraries
6285 to be linked with the current source (-l arguments). Changes
6286 currently will affect only the pic16 port.
6287 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6288 include path the port specific paths and port specific libraries,
6289 * gplink command now contains the $3 argument,
6290 * src/pic16/device.h,
6291 * src/pic16/device.c,: structure PIC_device is made public and
6292 renamed to PIC16_device, the same for variable Pics which is renamed

6307 Documenting changes from previous commits.
6308 * configure.in (version 1.56),
6309 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6310 when generating output files to configure the pic16 library,
6311 but now I've commented it out, since gputils aren't installed in the
6312 SF compile farm, so library won't compile
6314 * device/lib/Makefile.in (version 1.56): initially I've added in
6315 target 'all' the prerequestive 'model-pic16' so it compiled the
6316 pic16 library, but now I've commented it out for the same reasons
6318 * added targets 'model-pic16' and 'objects-pic16' to compile the
6320 * added target 'port-specific-objects-pic16' to handle the
6321 generated libraries and copy them into the build/ directory
6322 * added target 'clean-intermediate-pic16' to clean intermediate
6323 files into pic16 directory
6324 * in target 'installdirs' added line to create directory pic16 in

6328 added lines to copy all header files to installation path,
6329 * in target 'installdirs' added line create directory for pic16
6330 headers in the installation path

6590 * src/SDCCsymt.c (newEnumType),
6592 * support/Util/SDCCerr.c,
6593 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6595 * support/regression/tests/enum.c: added test for enum values that
6596 require at least 2 bytes of storage.
6598 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6600 * src/common.h: added ifndef/define/endif macros
6601 around the header file.
6602 Bug reported from Jesus Calvino-Fraga
6604 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6606 * sdcc.spec: updated
6607 * device/include/Makefile.in: don't install CVS directories
6608 * device/lib/Makefile.in: added removal of CVS directories after install
6609 * doc/Makefile: fixed install, added local_icons
6610 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6611 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6612 * src/ds390/gen.c (genRightShift): fixed bug #870788
6613 * src/SDCCast.c (decorateType): fixed bug #870781
6615 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6617 PIC16 port related changes:
6618 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6619 added variable stackPos,
6621 * gen.c: genCall, assignResultValue: added support for
6622 pushing/retrieving function parameters to/from stack,
6623 genFunction,genEndFunction: setup stack frame for the
6625 genAddrOf: will be changed according to bug 863624
6627 * added files genutils.c and genutils.h which contain gen*
6628 debugged and optimised functions extracted from gen.c
6630 * glue.c: added variable 'externs' which holds extern symbols,
6631 pic16emitRegularMap: is modified to properly handle relocatable
6632 symbols under the new scheme,
6633 pic16createInterruptVect: is modified
6634 pic16printPublics: is modified to emit 'global' assembler directives,
6635 added pic16_printExterns to print extern symbols,
6636 pic16glue: initializes stack/frame pointer in the beginning of
6637 the assembly output. Temporary hack, will be corrected later,
6638 because gplink yet does not support stack and SDCC does not
6639 yet support a type of crt0.o object to create the final binary.
6641 * Removed many lines that contain 8051 legacy code.
6642 * The code is finally placed under a 'code' directive.
6643 * Added port specific options.
6645 * _process_pragma: simplified since now we do not need *special*
6646 include file to define SFR registers. But a separate header
6647 will be needed. This will be developed later.
6648 * _pic16_parseOptions: added, parses port specific options:
6649 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6650 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6651 --preplace-udata-with=
6653 * _pic16_setDefaultOptions: modified to initialize section names,
6654 but hack is temporarly out of order since it needs improvement.
6655 * _pic16_genAssemblerPreamble: configuration words are emitted by
6656 their address instead of their name. This part is incomplete and
6657 supports only the 18Fxx2 devices. Other devices will emit an error
6658 during assembly since they do not contain the same set of config
6660 * _pic16_genIVT: is modified,
6662 * pcode.c: added definitions for some hardware registers that are needed
6664 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6665 All PCI entries are updated. Now LFSR is supported.
6666 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6667 * added pic16_newpCodeOpLit2 to support instructions with
6668 two literal arguments
6669 * pic16_pCode2str: corrected code that emits assembler instructions
6670 with two literal operands and those that have an access bit modifier
6671 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6672 this fixes a bug which caused some labels to be lost, when an
6673 assembler directive was added, i.e. banksel,
6674 * pic16_FixRegisterBanking: improved logic that causes the insertion
6676 * InlineFunction: functions that are called once, are not any more
6677 inlined. This can be a port option in the future,
6679 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6681 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6682 hold the corresponding uninitialized symbols,
6683 * pic16_allocProcessorRegister: registers have explicit marked the
6685 * pic16_allocInternalRegister: registers are explicit marked as
6687 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6688 processing list, so bit registers were lost,
6691 * ralloc.h: added field 'accessBank' and original symbol operand
6692 in register definition,
6693 * removed the field isMapped from register definition,
6695 ** Several functions have been removed from various sources:
6696 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6697 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6698 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6699 pic16_assignRelocatableRegisters
6701 ** others have been introduced:
6702 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6703 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6705 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6707 * support/scripts/inc2h.pl: changed definition of BIT_AT
6708 to emit 'sbit at' instead of 'bit at'. This was a request.
6710 PIC16 port related preliminary changes:
6711 * gen.c: prefixed function popRegFromString with
6712 pic16_ and all references to it corrected
6713 * pcode.c: all pic16_pc_* hardware registers prefixed
6714 with underscore (_),
6715 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6716 * ralloc.c: newReg(): when register is REG_SFR then
6717 set address to rIdx,
6718 pic16_allocProcessorRegister(): marks register wasUsed=0
6719 pic16_writeUsedRegs(): added a call to assign processor
6720 registers via pic16_assignFixedRegisters
6722 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6724 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6725 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6726 variables in unused register banks. Also the SSEG is placed
6727 wherever there is enough space for it, and IDATA can be anywhere
6728 in internal RAM. For now compile using -Wl-Y[stack_size].
6729 The mem file is different for this option as well, since it
6730 makes no sense of talking about DSEG lenght.
6732 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6734 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6735 in certain cases, e.g. when ROM assignment, patch provided
6736 from Albert den Haan.
6738 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6881 * src/mcs51/peephole.def,
6882 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6977 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6979 * src/SDCCast.c (decorateType): disabled a transformation I added in
6980 revision 1.188 (access to fields of a structure at an absolute address);
6981 it breaks with bitfields, extern declarations, and gcse analysis.
6982 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6983 could be assigned through a pointer, so don't complain.
6984 * src/SDCCast.c (astErrors),
6986 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7624 support for standard C idiom of memory mapped variables; for
7625 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7626 to xdata int at 0x1234 tempvar = 1.
7627 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7628 provided by Akiya ISHIDA

7644 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7646 Fixed bug #621531 (const & volatile confusion in the type chain).
7647 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7648 refer to the const or volatile state of the pointer itself.

7740 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7741 fetching of the pointer
7742 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7743 copied from genNearPointerSet()
7744 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7745 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7759 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7761 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7762 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7763 type for bits was changed. It resulted in bit variables becoming
7764 global, which is not permitted in PIC 14 assembly output.
7766 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7768 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7781 A few small changes that speed up the peephole optimizer.
7785 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7787 Try to make the peephole optimizer smarter by maintaining
7788 an association between the assembly source code and the
7789 iCodes that originated them. Put this information to use
7790 with a new peephole rule condition "notVolatile" so that
7791 the rules can be aggressive yet still safe.
7796 * src/mcs51/peeph.def
7798 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7802 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7803 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7804 if the left or right operand symbols have the accuse flag set.
7806 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7808 Changed the type of the result of the ! (NOT) operator to char;
7809 previously it returned the same type as the source. This allows
7810 us to eliminate all the genFloatNot functions (all of its target
7811 implementations were very buggy) since !float can use the same
7814 * src/SDCCicode.c (ast2iCode): ! returns char

7823 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7824 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7825 during interrupts. Ensure WSAVE is located at a shared bank address.
7826 2. Fixed page selection in some places
7827 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7828 the registers name strings.
7829 4. Fixed "signed / unsigned compare" compiler warnings.
7830 5. The PIC port manages its own allocation of the general purpose
7831 registers, but makes no attempt to reuse them. As a result when
7832 compiling it soon runs out of general purpose registers. Some
7833 additional code was added to the files pcode.c and device.c to walk
7834 through the function call tree and rename the registers so that they
7844 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7845 genPlus() & genMinus() when the result is the same as left or right

7851 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7853 Made bitfield a distinct type from bit so that bitfields
7854 convert as per ANSI C and bits retain their traditional
7855 boolean style behaviour. Implemented bitfield support in
7863 * src/ds390/gen.c: bit v bitfield split
7864 * src/z80/gen.c: New support for bitfields
7865 * support/regression/tests/bitfields.c: reenabled z80,
7868 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7870 Rules 246.x, 247.x relate to bitfields, the others speed up
7871 access to xdata mapped I/O devices.
7873 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7875 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7877 Cleaned up genPackBits and genUnpackBits and added two helper
7878 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7879 for literal assignments in genPackBits (thanks to Frieder for
7885 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7887 Fixed bug #748310 (pointer to function type mishandled when the
7888 function name is omitted). Also fixed a SIGSEGV when a function
7889 attribute (reentrant, etc) is used on a non-function or on a
7890 function but misplaced before the parameter list.
7892 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7894 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7895 * support/Util/SDCCerr.h,
7896 * support/Util/SDCCerr.c: Added func attr misuse error msg

7917 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7919 Made the constant following the "interrupt" keyword optional. If
7920 omitted, the function will not automatically be given an entry
7921 in the interrupt vector table (similar to #pragma NOIV, but
7922 less syntacticly kludgy). The interrupt number is also now
7923 range checked. Also fixed a bug in the high order bit example

7937 * src/SDCCicode.c (operandOperation): rewritten some ops
7938 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7939 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7941 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7942 be re-activated by defining REDUCE_LITERALS)
7943 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7944 unsigned, but are signed by default
7945 * src/SDCCval.c (constVal): rearranged
7946 * src/SDCCval.c (valMod): preliminary fix
7947 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8453 added if/endif conditional macros to remove options help
8454 messages from optionsTable when a port is not configured, added
8455 support for the PIc16 port in the ports table, when executing
8456 the compiler with no port specified on command line, a default
8457 port is selected with the new macro DEFAULT_PORT which is
8458 defined in port.h, in setDefaultOptions() linkOptions is removed
8459 from initialization assignment, since now it is a set,
8460 parseCmdLine uses setParseWithComma for linkOptions, in
8461 linkEdit() linkOptions are accessed with new function indexSet()
8462 which returns the i'th item of a set variable. See SDCCset.c, in
8463 linkEdit() when calling buildCmdLine(), added linkOptions as
8464 last argument. Now users can pass arguments to gplink via the
8465 -Wl option, main() uses pic16glue() to glue up pic16 programs

8479 gpasm complaining and test the linkage with gplink, _linkCmd and
8480 _asmCmd changed to be more gplink and gpasm friendly
8481 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8482 produced an error when parsed, peep rule 12 is added to utilize
8483 movff, but it is commented out since the pCode does not support
8484 yet a command with 2 address arguments
8486 2003-05-18 <johan AT balder>
8488 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8515 2003-05-11 Borut Razem <borut.razem AT siol.net>
8517 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9517 2003-01-06 <karl AT turbobit.com>
9518 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
9521 2003-01-06 <johan AT balder>
9523 * src/SDCCicode.c: fixed array add
9525 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9526 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9527 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9529 2003-01-04 <johan AT balder>
9531 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9533 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9534 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9536 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9537 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9538 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9540 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9541 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9543 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9544 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9546 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9547 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9549 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9551 * in \sdcc\as\mcs51\ changed these files in order to create an
9552 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9553 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9554 following files to include the previous two files: aslink.dsp,
9555 Makefile.aslink, Makefile.bcc, and Makefile.in.
9557 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9558 .adb instead of .cdb
9560 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9562 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9563 value from option --iram-size.
9565 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9567 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9570 2002-09-18 <wiml AT hhhh.org>
9572 * SDCClrange.h: exposed setFromRange() and setToRange()
9573 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9574 packRegsForAccUse() (bug 542397)
9575 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9576 multiple times and emitting the fetch operations more than once
9577 added aopGetUsesAcc() function to allow binary operators to
9578 fetch their operands in the correct order; made genMinus() emit
9579 compact code for X = LITERAL - Y
9581 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9582 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9583 sprintf() in line 1267.
9585 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9586 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9589 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9590 Changes to aslink (All the changes are marked with 'JCF'):
9592 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9595 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9596 area BSEG. Also moves, if possible, the DATA area down into the internal
9597 ram so more space is available.
9599 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9602 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9603 not bytes. Function summary() which creates a memory usage summary
9604 file with extension .mem. Reports of overlaping stack and small stack
9605 size. If the space for the stack is less than 16 bytes aslink trows a
9608 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9609 the 8051. Option 'y' for memory summary output file.
9611 Changes to sdcc (All the changes are marked with 'JCF'):
9613 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9615 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9616 overlaying area for it (uses RegBankUsed[4]).
9618 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9619 bank zero as used by default. By default aslink locates the stack
9620 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9621 the creation of the .mem file. Delegates the allocation of data area
9622 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9623 the begining of the stack area to aslink.
9625 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9626 glue() in SDCCglue.c creates an area for it.
9628 2002-09-03 Borut Razem <borut.razem AT siol.net>
9629 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9630 sdcc/src/pic/glue.c:
9631 introduced atexit() handler for teporay files removal in case of
9632 errors, assertions, ...
9634 2002-08-29 Borut Razem <borut.razem AT siol.net>
9635 * sdcc/support/cpp2/auto-host_vc_in.h:
9636 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9637 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9638 Maybe there is a similar problem with BORLANDC? It should be checked!
9640 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9641 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9642 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9643 was not executed, and the compiler (cl) launched a warning:
9644 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9646 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9647 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9649 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9650 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9652 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9653 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9654 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9655 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9656 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9657 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9658 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9659 - added Release configuration in VS projects
9660 - review of compiler an linker options
9661 - VC .exe files are generated in bin_vc directory, not to interfere
9662 with binaries generated from other projects (cygwin, mingw, bcc ...)
9664 * sdcc/src/yacc.dsp: added
9666 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9667 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9668 and insert the version number definitions from .version
9670 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9672 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9673 added - genarate auto-host.h using auto-host_vc_in.h as template
9676 removed from CVS, generated automatically
9678 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9679 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9681 2002-08-11 Borut Razem <borut.razem AT siol.net>
9682 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9684 2002-08-10 Borut Razem <borut.razem AT siol.net>
9685 * src/SDCCmain.c (main):
9686 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9687 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9688 The consequence was that some temporary files were not removed.
9691 unification of code in functions tempfilename() and tempfile():
9692 function tempnam() is defined in Visual Studio 6.0 and .NET
9694 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9696 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9697 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9698 - removed compiler command line option /WX: Treats all warnings as errors
9699 - update a list of source files, included into the project
9701 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9702 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9703 changed project type to Generic Project so that can be correcly converted to VS.NET project
9705 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9707 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9709 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9711 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9712 added return 0 statements after assert() to make compiler happy
9714 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9715 added newline in the def file to keep MSC compiler satisfied
9717 * sdcc/src/z80/gen.c:
9718 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9719 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9720 - solved MSC error in function aopDump()
9722 * sdcc_vc.h: define PREFIX as "\\sdcc"
9724 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9725 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9728 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9729 - Rewrote the register banking algorithm.
9730 - Added pCode live-range analysis to registers (for now, only non-used and
9731 singly-used registers optimized away)
9733 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9735 * 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.

9764 2002-03-28 Johan Knol <johan AT balder>
9766 * src/SDCCval.c: fixed bug #532436
9768 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9770 Added "char *Processor" field to the port structure.
9773 Added -p option. Allows port dependent processor to be specified.
9776 Initialized the new field char *Processor field to NULL in all ports
9779 Compiler generated registers for interrupt context saving
9780 were not getting allocated.
9782 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9785 Fixed left shift. Will promote the left side of a left shift
9786 if a) left shifting more than size of operand or b) when assigned
9787 to something size > size of left side
9789 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9791 tons of changes. Register allocation has been
9792 rewritten. Added customization for the various PICs. Flow
9793 analysis is restructured. ...
9799 Added. device.c is a PIC port hack to accomodate variations
9802 2002-03-13 Michael Hope <michaelh AT vroom>
9804 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9806 2002-03-04 johanknol <johanknol AT manik>

9813 2002-03-04 bela <bela AT manik>
9815 * /device/include/mcs51reg.h:
9816 ds89c420 register definition update
9818 2002-03-03 <johan AT FRIJA>

9897 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9899 * sdcc/src/SDCCloop.c:
9900 Previous fix was not good. basic blocks that have "break" or "return" are
9901 not really partof a loop , but live ranges used in these blocks should
9902 be live thru the entire loop, so set partOfLoop but don't add them to
9905 2002-02-21 <johan AT FRIJA>
9907 * src/SDCCcse.c: fixed bug #514308
9909 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9912 Fixed BUG #519583. If a conditional block ended in a return/break
9913 statement inside a loop, it was not being considered part of the loop.
9915 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9917 2002-02-10 Karl Bongers <karl AT turbobit.com>
9920 Fixed up SDCDB debugger somewhat. Updated debugger/README
9921 with lots of comments and notes.
9923 * device/examples/test2.c:
9924 Fix bug, "red" variable not being initialized(compiler complained).
9926 * device/examples/Makefile, examples/test3.c:
9927 Add Makefile in device/examples folder, compiles test3.c
9928 for use as a multiple module SDCDB test case.
9930 * sim/ucsim/cmd.src/cmdset.cc:
9931 Took out debug printfs in ucsim "next" command.
9934 Karl and Johan start ucsim XA support. Most dissassembly working,
9935 about 75% emulation done(plenty of work remaining).
9937 * sim/ucsim/z80.src:
9938 Add Z80 support to ucsim, add test-ucz80 regression test,
9939 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9940 Notice z80 compiler fails on examples/test3.c/crc code.

9958 2) ralloc can now allocate DPTR1 to some liveRanges
9960 * src/SDCCsymt.c, src/SDCCsymt.h:
9961 changes to handle multiple sends & receives
9964 added some pointer arithmetic optimization
9967 added some pointer arithmetic optimizations but not stable yet so not
9968 called from anywhere (will get this working shortly)
9970 * src/SDCCopt.c: fixed for multiple sends & receives
9973 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9974 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9975 set preprocessor defines (depending on options)
9977 * src/SDCCicode.c, src/SDCCicode.h:
9978 changes made to handle multiple sends & receives
9981 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
