1 2006-03-16 Raphael Neider <rneider AT web.de>
3 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
4 the left operand is shorter than the result (c* = lit-c* + int),
6 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
9 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
11 * src/.version: increased version number to 2.5.5
12 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
13 linking is done manually in pic16 port's _linkEdit,
14 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
15 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
16 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
17 allocate asmop as AOP_ACC,
18 (aopForRemat): added parameter 'bool result' in function declaration,
19 (pic16_aopGet): return AOP_ACC when accessing WREG,
20 (pic16_popGetTempReg): minor modification,
21 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
23 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
24 calling function in absolute addresses,
25 (genAssign): take into account AOP_ACC asmop,
26 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
27 * src/pic16/pcoderegs.c: some debug functions and lines added,
28 * src/pic16/ralloc.c (decodeRegType): added but commented out,
29 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
31 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
32 call to allocReg, not by manually allocating a new one,
33 (pic16_assignRegisters): now before going through the register
34 allocating functions mark all registers as free. This eliminates some
35 side effects resulting from peephole parser done earlier in the backbone
37 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
39 * src/SDCCicode.c (geniCodeLogic),

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

84 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
85 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
87 2006-03-06 Borut Razem <borut.razem AT siol.net>
89 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
92 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

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

2394 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2395 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2396 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2397 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2398 always available in leading double underscore form. The C99 support is
2399 mostly missing, but it's a start.
2400 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2401 reserved identifier "__data".
2403 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2477 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2479 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2481 * device/lib/printf_large.c: removed inline assembly for portability and
2482 readability. Use printf_fast if speed or size are more important.
2483 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2484 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2486 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2488 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2489 prevent compiler warning
2491 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2493 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2494 moved to level 0 and declared as static. Also they are explicit
2495 placed in access bank. This was necessery because some times they
2496 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2497 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2498 optimizations. Currently only compare to unsigned char is implemented,
2499 * src/pic16/gen.c: added fReturnIdx array,
2500 * (struct resolvedIfx) is moved to gen.h and made public,
2501 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2502 * (aopForSym): added an optimization to directly store in stack of
2503 the operand of a SEND iCode,
2504 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2505 but as registers instead (AOP_REG) using the fReturnIdx array,
2506 * (pic16_freeAsmop): remove the freed register from the
2507 _G.sregsAlloc field,
2508 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2509 a compare of 'WREG',
2510 * (pic16_popGetTempRegCond): changed function prototype, now
2511 function takes also a bitVector argument v which holds the current
2512 set of registers that are allocated for stack access by aopForSym,
2513 registers allocated in aopForSym for accessing stack symbols are not
2514 any more part of the functions usedRegs field,
2515 * (genCall): some times aopOp is called for a stack variable to be
2516 send, aopForSym might perform the push, if this is true make sure
2517 that genCall doesn't push the variable twice by testing _G.resDirect,
2518 * (genFunction): changed testing for unspecified interrupt number
2519 from 256 to INTNO_UNSPEC,
2520 * modified selection scheme of frame pointer generation. Previously
2521 if function did use local registers a frame pointer was generated,
2522 now a frame pointer is generated only if function has arguments
2523 (that need PLUSW2 register access), or has stack arguments, or the
2524 compiler is not instructed to omit the frame pointer,
2525 * (genEndFunction): before restoring local registers that were saved
2526 in the function preamble, also restore the registers that *might*
2527 have been allocated for stack access,
2528 * (genRet): removed some old comments,
2529 * (genCmp, the active (RN's) version): added a call to the
2530 pic16_genCmp_special function to perform the compare with a more
2531 robust and optimized way,
2532 * (genInline): a feature has been added in inline code generation,
2533 which allows a wildcard variable substitution when writing inline
2534 assembly. Code is incomplete and experimental therefore undocumented,
2535 * (genCast): changed order of aopOp for result and right to allow
2536 aopForSym to directly load the result if possible,
2537 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2538 perform an optimized compare on some selected special occasions,
2539 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2540 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2541 generate an IVT any more,
2542 * src/pic16/main.c (pic16_optionsTable): added command line option
2544 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2545 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2547 * src/pic16/NOTES: Raphael Neider added in list of active developers
2548 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2549 jumptable_end to prevent bug #,
2550 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2551 inCond and outCond fields,
2552 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2553 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2554 turn off register spilling,
2555 * (packRegsForOneUse): synced with other ports' versions although it
2556 is not used currently,
2557 * (pic16_packRegisters): added an optimization while reading
2558 structure bitfields, some registers may be saved (malloc code is
2559 decreased by 80 bytes)
2561 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2563 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2564 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2565 this can be optimized more?
2567 2005-03-10 Raphael Neider <rneider AT web.de>
2569 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2570 genNearPointerGet): (hopefully) fixed access to bitfields via
2571 pointers (p->bitN = x; and x = p->bitN; failed)
2573 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2575 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
2577 2005-03-09 Raphael Neider <rneider AT web.de>
2579 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
2581 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
2583 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
2584 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,

3205 Adding support for replacing ljmps with sjmps in jumptables
3206 generated for switch statements. For now you need to set the
3207 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3208 Now 4 algorithms for mcs51 jumptable generation are used:
3209 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3210 addresses loaded pc-relative for up to 112 cases and stack-pushing
3211 target addresses loaded with offset from dptr for up to 256 cases.

3241 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3243 * added libc directory. The current version of LibC contains string
3244 functions, ctype functions and macros and some functions of the
3245 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3246 be extensively tested in the future. Standard disclaimer here.
3247 Library is not automatically build yet. But one can build it by
3248 invoking 'make' inside the libc directory.

3259 * (pic16_storeForReturn): optimized return of 0,
3260 * (genCmp): experimental code for new genCmp which uses PIC18's
3261 special compare&skip instructions. Initial tests fail some times
3262 with variables grater than 1 byte in size, so new code is disabled,
3263 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3265 * (genCast): began a fix to optimize the casting of a bit to another
3266 bit, now assigning a bitfield to another bitfield will fail, sorry,

3275 and 1 for banking instruction,
3276 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3277 caused stop processing pCodes after a inline assembly block,
3278 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3280 registers when it shouldn't,
3281 * src/pic16/ralloc.c (allocReg): add preliminary support for
3282 supporting a limited set of temporary registers,
3284 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3290 (genFunction): optimize RECEIVE iCodes in reentrant functions
3292 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3294 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6292 loaded with the linker search paths (-L arguments) and the libraries
6293 to be linked with the current source (-l arguments). Changes
6294 currently will affect only the pic16 port.
6295 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6296 include path the port specific paths and port specific libraries,
6297 * gplink command now contains the $3 argument,
6298 * src/pic16/device.h,

6315 Documenting changes from previous commits.
6316 * configure.in (version 1.56),
6317 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6318 when generating output files to configure the pic16 library,
6319 but now I've commented it out, since gputils aren't installed in the
6320 SF compile farm, so library won't compile
6322 * device/lib/Makefile.in (version 1.56): initially I've added in
6323 target 'all' the prerequestive 'model-pic16' so it compiled the
6324 pic16 library, but now I've commented it out for the same reasons
6326 * added targets 'model-pic16' and 'objects-pic16' to compile the
6328 * added target 'port-specific-objects-pic16' to handle the
6329 generated libraries and copy them into the build/ directory
6330 * added target 'clean-intermediate-pic16' to clean intermediate
6331 files into pic16 directory
6332 * in target 'installdirs' added line to create directory pic16 in

6597 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6598 * src/SDCCsymt.c (newEnumType),
6600 * support/Util/SDCCerr.c,
6601 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6603 * support/regression/tests/enum.c: added test for enum values that
6604 require at least 2 bytes of storage.
6606 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6608 * src/common.h: added ifndef/define/endif macros
6609 around the header file.
6610 Bug reported from Jesus Calvino-Fraga
6612 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6614 * sdcc.spec: updated
6615 * device/include/Makefile.in: don't install CVS directories
6616 * device/lib/Makefile.in: added removal of CVS directories after install
6617 * doc/Makefile: fixed install, added local_icons
6618 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6619 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6620 * src/ds390/gen.c (genRightShift): fixed bug #870788
6621 * src/SDCCast.c (decorateType): fixed bug #870781
6623 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6625 PIC16 port related changes:
6626 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6627 added variable stackPos,
6629 * gen.c: genCall, assignResultValue: added support for
6630 pushing/retrieving function parameters to/from stack,
6631 genFunction,genEndFunction: setup stack frame for the
6633 genAddrOf: will be changed according to bug 863624
6635 * added files genutils.c and genutils.h which contain gen*
6636 debugged and optimised functions extracted from gen.c
6638 * glue.c: added variable 'externs' which holds extern symbols,
6639 pic16emitRegularMap: is modified to properly handle relocatable
6640 symbols under the new scheme,
6641 pic16createInterruptVect: is modified
6642 pic16printPublics: is modified to emit 'global' assembler directives,
6643 added pic16_printExterns to print extern symbols,
6644 pic16glue: initializes stack/frame pointer in the beginning of
6645 the assembly output. Temporary hack, will be corrected later,
6646 because gplink yet does not support stack and SDCC does not
6647 yet support a type of crt0.o object to create the final binary.
6649 * Removed many lines that contain 8051 legacy code.
6650 * The code is finally placed under a 'code' directive.
6651 * Added port specific options.
6653 * _process_pragma: simplified since now we do not need *special*
6654 include file to define SFR registers. But a separate header
6655 will be needed. This will be developed later.
6656 * _pic16_parseOptions: added, parses port specific options:
6657 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6658 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6659 --preplace-udata-with=
6661 * _pic16_setDefaultOptions: modified to initialize section names,
6662 but hack is temporarly out of order since it needs improvement.
6663 * _pic16_genAssemblerPreamble: configuration words are emitted by
6664 their address instead of their name. This part is incomplete and
6665 supports only the 18Fxx2 devices. Other devices will emit an error
6666 during assembly since they do not contain the same set of config
6668 * _pic16_genIVT: is modified,
6670 * pcode.c: added definitions for some hardware registers that are needed
6672 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6673 All PCI entries are updated. Now LFSR is supported.
6674 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6675 * added pic16_newpCodeOpLit2 to support instructions with
6676 two literal arguments
6677 * pic16_pCode2str: corrected code that emits assembler instructions
6678 with two literal operands and those that have an access bit modifier
6679 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6680 this fixes a bug which caused some labels to be lost, when an
6681 assembler directive was added, i.e. banksel,
6682 * pic16_FixRegisterBanking: improved logic that causes the insertion
6684 * InlineFunction: functions that are called once, are not any more
6685 inlined. This can be a port option in the future,
6687 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6689 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6690 hold the corresponding uninitialized symbols,
6691 * pic16_allocProcessorRegister: registers have explicit marked the
6693 * pic16_allocInternalRegister: registers are explicit marked as
6695 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6696 processing list, so bit registers were lost,
6699 * ralloc.h: added field 'accessBank' and original symbol operand
6700 in register definition,
6701 * removed the field isMapped from register definition,
6703 ** Several functions have been removed from various sources:
6704 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6705 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6706 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6707 pic16_assignRelocatableRegisters
6709 ** others have been introduced:
6710 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6711 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6713 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6715 * support/scripts/inc2h.pl: changed definition of BIT_AT
6716 to emit 'sbit at' instead of 'bit at'. This was a request.
6718 PIC16 port related preliminary changes:
6719 * gen.c: prefixed function popRegFromString with
6720 pic16_ and all references to it corrected
6721 * pcode.c: all pic16_pc_* hardware registers prefixed
6722 with underscore (_),
6723 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6724 * ralloc.c: newReg(): when register is REG_SFR then
6725 set address to rIdx,
6726 pic16_allocProcessorRegister(): marks register wasUsed=0
6727 pic16_writeUsedRegs(): added a call to assign processor
6728 registers via pic16_assignFixedRegisters
6730 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6732 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6733 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6734 variables in unused register banks. Also the SSEG is placed
6735 wherever there is enough space for it, and IDATA can be anywhere
6736 in internal RAM. For now compile using -Wl-Y[stack_size].
6737 The mem file is different for this option as well, since it
6738 makes no sense of talking about DSEG lenght.
6740 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6742 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6743 in certain cases, e.g. when ROM assignment, patch provided
6744 from Albert den Haan.

6889 * src/mcs51/peephole.def,
6890 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6985 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6987 * src/SDCCast.c (decorateType): disabled a transformation I added in
6988 revision 1.188 (access to fields of a structure at an absolute address);
6989 it breaks with bitfields, extern declarations, and gcse analysis.
6990 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6991 could be assigned through a pointer, so don't complain.
6992 * src/SDCCast.c (astErrors),
6994 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7632 support for standard C idiom of memory mapped variables; for
7633 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7634 to xdata int at 0x1234 tempvar = 1.
7635 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7636 provided by Akiya ISHIDA

7652 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7654 Fixed bug #621531 (const & volatile confusion in the type chain).
7655 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7747 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7748 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7749 fetching of the pointer
7750 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7751 copied from genNearPointerSet()
7752 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7753 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7767 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7769 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7770 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7771 type for bits was changed. It resulted in bit variables becoming
7772 global, which is not permitted in PIC 14 assembly output.
7774 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7776 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7789 A few small changes that speed up the peephole optimizer.
7793 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7795 Try to make the peephole optimizer smarter by maintaining
7796 an association between the assembly source code and the
7797 iCodes that originated them. Put this information to use
7798 with a new peephole rule condition "notVolatile" so that
7799 the rules can be aggressive yet still safe.
7804 * src/mcs51/peeph.def
7806 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7810 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7811 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7812 if the left or right operand symbols have the accuse flag set.
7814 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7816 Changed the type of the result of the ! (NOT) operator to char;
7817 previously it returned the same type as the source. This allows
7818 us to eliminate all the genFloatNot functions (all of its target
7819 implementations were very buggy) since !float can use the same
7822 * src/SDCCicode.c (ast2iCode): ! returns char

7831 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7832 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7833 during interrupts. Ensure WSAVE is located at a shared bank address.
7834 2. Fixed page selection in some places
7835 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7836 the registers name strings.
7837 4. Fixed "signed / unsigned compare" compiler warnings.
7838 5. The PIC port manages its own allocation of the general purpose
7839 registers, but makes no attempt to reuse them. As a result when
7840 compiling it soon runs out of general purpose registers. Some
7841 additional code was added to the files pcode.c and device.c to walk
7842 through the function call tree and rename the registers so that they
7852 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7853 genPlus() & genMinus() when the result is the same as left or right

7859 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7861 Made bitfield a distinct type from bit so that bitfields
7862 convert as per ANSI C and bits retain their traditional
7863 boolean style behaviour. Implemented bitfield support in
7871 * src/ds390/gen.c: bit v bitfield split
7872 * src/z80/gen.c: New support for bitfields
7873 * support/regression/tests/bitfields.c: reenabled z80,
7876 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7878 Rules 246.x, 247.x relate to bitfields, the others speed up
7879 access to xdata mapped I/O devices.
7881 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7883 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7885 Cleaned up genPackBits and genUnpackBits and added two helper
7886 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7887 for literal assignments in genPackBits (thanks to Frieder for
7893 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7895 Fixed bug #748310 (pointer to function type mishandled when the
7896 function name is omitted). Also fixed a SIGSEGV when a function
7897 attribute (reentrant, etc) is used on a non-function or on a
7898 function but misplaced before the parameter list.
7900 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7902 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7903 * support/Util/SDCCerr.h,
7904 * support/Util/SDCCerr.c: Added func attr misuse error msg

7925 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7927 Made the constant following the "interrupt" keyword optional. If
7928 omitted, the function will not automatically be given an entry
7929 in the interrupt vector table (similar to #pragma NOIV, but
7930 less syntacticly kludgy). The interrupt number is also now
7931 range checked. Also fixed a bug in the high order bit example

7945 * src/SDCCicode.c (operandOperation): rewritten some ops
7946 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7947 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7949 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7950 be re-activated by defining REDUCE_LITERALS)
7951 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7952 unsigned, but are signed by default
7953 * src/SDCCval.c (constVal): rearranged
7954 * src/SDCCval.c (valMod): preliminary fix
7955 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8461 added if/endif conditional macros to remove options help
8462 messages from optionsTable when a port is not configured, added
8463 support for the PIc16 port in the ports table, when executing
8464 the compiler with no port specified on command line, a default
8465 port is selected with the new macro DEFAULT_PORT which is
8466 defined in port.h, in setDefaultOptions() linkOptions is removed
8467 from initialization assignment, since now it is a set,
8468 parseCmdLine uses setParseWithComma for linkOptions, in
8469 linkEdit() linkOptions are accessed with new function indexSet()
8470 which returns the i'th item of a set variable. See SDCCset.c, in
8471 linkEdit() when calling buildCmdLine(), added linkOptions as
8472 last argument. Now users can pass arguments to gplink via the
8473 -Wl option, main() uses pic16glue() to glue up pic16 programs

8487 gpasm complaining and test the linkage with gplink, _linkCmd and
8488 _asmCmd changed to be more gplink and gpasm friendly
8489 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8490 produced an error when parsed, peep rule 12 is added to utilize
8491 movff, but it is commented out since the pCode does not support
8492 yet a command with 2 address arguments
8494 2003-05-18 <johan AT balder>
8496 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8523 2003-05-11 Borut Razem <borut.razem AT siol.net>
8525 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9525 2003-01-06 <karl AT turbobit.com>
9526 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
9529 2003-01-06 <johan AT balder>
9531 * src/SDCCicode.c: fixed array add
9533 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9534 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9535 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9537 2003-01-04 <johan AT balder>
9539 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9541 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9542 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9544 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9545 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9546 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9548 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9549 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9551 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9552 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9554 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9555 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9557 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9559 * in \sdcc\as\mcs51\ changed these files in order to create an
9560 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9561 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9562 following files to include the previous two files: aslink.dsp,
9563 Makefile.aslink, Makefile.bcc, and Makefile.in.
9565 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9566 .adb instead of .cdb
9568 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9570 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9571 value from option --iram-size.
9573 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9575 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9578 2002-09-18 <wiml AT hhhh.org>
9580 * SDCClrange.h: exposed setFromRange() and setToRange()
9581 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9582 packRegsForAccUse() (bug 542397)
9583 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9584 multiple times and emitting the fetch operations more than once
9585 added aopGetUsesAcc() function to allow binary operators to
9586 fetch their operands in the correct order; made genMinus() emit
9587 compact code for X = LITERAL - Y
9589 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9590 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9591 sprintf() in line 1267.
9593 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9594 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9597 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9598 Changes to aslink (All the changes are marked with 'JCF'):
9600 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9603 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9604 area BSEG. Also moves, if possible, the DATA area down into the internal
9605 ram so more space is available.
9607 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9610 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9611 not bytes. Function summary() which creates a memory usage summary
9612 file with extension .mem. Reports of overlaping stack and small stack
9613 size. If the space for the stack is less than 16 bytes aslink trows a
9616 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9617 the 8051. Option 'y' for memory summary output file.
9619 Changes to sdcc (All the changes are marked with 'JCF'):
9621 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9623 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9624 overlaying area for it (uses RegBankUsed[4]).
9626 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9627 bank zero as used by default. By default aslink locates the stack
9628 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9629 the creation of the .mem file. Delegates the allocation of data area
9630 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9631 the begining of the stack area to aslink.
9633 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9634 glue() in SDCCglue.c creates an area for it.
9636 2002-09-03 Borut Razem <borut.razem AT siol.net>
9637 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9638 sdcc/src/pic/glue.c:
9639 introduced atexit() handler for teporay files removal in case of
9640 errors, assertions, ...
9642 2002-08-29 Borut Razem <borut.razem AT siol.net>
9643 * sdcc/support/cpp2/auto-host_vc_in.h:
9644 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9645 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9646 Maybe there is a similar problem with BORLANDC? It should be checked!
9648 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9649 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9650 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9651 was not executed, and the compiler (cl) launched a warning:
9652 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9654 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9655 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9657 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9658 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9660 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9661 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9662 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9663 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9664 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9665 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9666 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9667 - added Release configuration in VS projects
9668 - review of compiler an linker options
9669 - VC .exe files are generated in bin_vc directory, not to interfere
9670 with binaries generated from other projects (cygwin, mingw, bcc ...)
9672 * sdcc/src/yacc.dsp: added
9674 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9675 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9676 and insert the version number definitions from .version
9678 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9680 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9681 added - genarate auto-host.h using auto-host_vc_in.h as template
9684 removed from CVS, generated automatically
9686 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9687 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9689 2002-08-11 Borut Razem <borut.razem AT siol.net>
9690 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9692 2002-08-10 Borut Razem <borut.razem AT siol.net>
9693 * src/SDCCmain.c (main):
9694 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9695 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9696 The consequence was that some temporary files were not removed.
9699 unification of code in functions tempfilename() and tempfile():
9700 function tempnam() is defined in Visual Studio 6.0 and .NET
9702 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9704 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9705 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9706 - removed compiler command line option /WX: Treats all warnings as errors
9707 - update a list of source files, included into the project
9709 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9710 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9711 changed project type to Generic Project so that can be correcly converted to VS.NET project
9713 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9715 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9717 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9719 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9720 added return 0 statements after assert() to make compiler happy
9722 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9723 added newline in the def file to keep MSC compiler satisfied
9725 * sdcc/src/z80/gen.c:
9726 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9727 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9728 - solved MSC error in function aopDump()
9730 * sdcc_vc.h: define PREFIX as "\\sdcc"
9732 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9733 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9736 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9737 - Rewrote the register banking algorithm.
9738 - Added pCode live-range analysis to registers (for now, only non-used and
9739 singly-used registers optimized away)
9741 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9743 * 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.

9772 2002-03-28 Johan Knol <johan AT balder>
9774 * src/SDCCval.c: fixed bug #532436
9776 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9778 Added "char *Processor" field to the port structure.
9781 Added -p option. Allows port dependent processor to be specified.
9784 Initialized the new field char *Processor field to NULL in all ports
9787 Compiler generated registers for interrupt context saving
9788 were not getting allocated.
9790 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9793 Fixed left shift. Will promote the left side of a left shift
9794 if a) left shifting more than size of operand or b) when assigned
9795 to something size > size of left side
9797 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9799 tons of changes. Register allocation has been
9800 rewritten. Added customization for the various PICs. Flow
9801 analysis is restructured. ...
9807 Added. device.c is a PIC port hack to accomodate variations
9810 2002-03-13 Michael Hope <michaelh AT vroom>
9812 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9905 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9907 * sdcc/src/SDCCloop.c:
9908 Previous fix was not good. basic blocks that have "break" or "return" are
9909 not really partof a loop , but live ranges used in these blocks should
9910 be live thru the entire loop, so set partOfLoop but don't add them to
9913 2002-02-21 <johan AT FRIJA>
9915 * src/SDCCcse.c: fixed bug #514308
9917 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9920 Fixed BUG #519583. If a conditional block ended in a return/break
9921 statement inside a loop, it was not being considered part of the loop.
9923 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9925 2002-02-10 Karl Bongers <karl AT turbobit.com>
9928 Fixed up SDCDB debugger somewhat. Updated debugger/README
9929 with lots of comments and notes.
9931 * device/examples/test2.c:
9932 Fix bug, "red" variable not being initialized(compiler complained).
9934 * device/examples/Makefile, examples/test3.c:
9935 Add Makefile in device/examples folder, compiles test3.c
9936 for use as a multiple module SDCDB test case.
9938 * sim/ucsim/cmd.src/cmdset.cc:
9939 Took out debug printfs in ucsim "next" command.
9942 Karl and Johan start ucsim XA support. Most dissassembly working,
9943 about 75% emulation done(plenty of work remaining).
9945 * sim/ucsim/z80.src:
9946 Add Z80 support to ucsim, add test-ucz80 regression test,
9947 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9948 Notice z80 compiler fails on examples/test3.c/crc code.

9966 2) ralloc can now allocate DPTR1 to some liveRanges
9968 * src/SDCCsymt.c, src/SDCCsymt.h:
9969 changes to handle multiple sends & receives
9972 added some pointer arithmetic optimization
9975 added some pointer arithmetic optimizations but not stable yet so not
9976 called from anywhere (will get this working shortly)
9978 * src/SDCCopt.c: fixed for multiple sends & receives
9981 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9982 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9983 set preprocessor defines (depending on options)
9985 * src/SDCCicode.c, src/SDCCicode.h:
9986 changes made to handle multiple sends & receives
9989 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
