14 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
15 implemented patch 1120823 Thanks to Willy De la Court (normal
16 interrupts need an interrupt number now if they are made critical),
17 and enabled nesting of critical functions though not for gbz80
18 (genCritical, genEndCritical): added functions
19 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
20 * src/z80/mappings.i: added "ei" to all mappings

26 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
27 archive with gcc 4.1 on mips and wrote the patch"
29 2006-03-16 Raphael Neider <rneider AT web.de>
31 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
32 the left operand is shorter than the result (c* = lit-c* + int),
34 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
37 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
39 * src/.version: increased version number to 2.5.5
40 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
41 linking is done manually in pic16 port's _linkEdit,
42 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
43 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
44 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
45 allocate asmop as AOP_ACC,
46 (aopForRemat): added parameter 'bool result' in function declaration,

59 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
60 call to allocReg, not by manually allocating a new one,
61 (pic16_assignRegisters): now before going through the register
62 allocating functions mark all registers as free. This eliminates some
63 side effects resulting from peephole parser done earlier in the backbone
65 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
67 * src/SDCCicode.c (geniCodeLogic),

86 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
87 (aopForSym, aopOp): increment asmop.allocated if reused,
88 (freeAsmop): decrement asmop.allocated and check for zero instead of
90 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
91 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

113 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
115 2006-03-06 Borut Razem <borut.razem AT siol.net>
117 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
118 made the linker quiet
120 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

123 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
124 which dumps before the function entry point a data byte which represents
125 the number of the local variables used by the specified function, added
126 'xinst' for initial support for Extended Instruction Support,
127 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
128 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
129 port->fun_prefix anymore (may change later),
130 (genFunction, genEndFunction): do not store/restore local registers for
131 _main (this should take care the --main-return command line option in
133 (genOr): removed some legacy pic-port instructions,
134 * src/pic16/genarith.c (genAddLit): re-enabled old code because
135 performing operations with SFR's causes data to be written more than
136 once to each SFR. Perhaps SFRs should be handled in special cases...
137 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
139 * src/pic16/main.c (_process_pragma): stack bound checking did not take
140 into account for stack starting position,
141 (struct OPTIONS pic16_optionsTable): added command line argument
142 --extended or -y for Extended Instruction Support,
143 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
144 (deassignLRs): *** perhaps the most important change, old 'for' code
145 (commented out for reference), didn't account for some registers which
146 were left marked 'not free' after a pointer operation. The change
147 reduces register usage a lot in some cases

2507 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2509 * device/lib/printf_large.c: removed inline assembly for portability and
2510 readability. Use printf_fast if speed or size are more important.
2511 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2512 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2514 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2516 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2517 prevent compiler warning
2519 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2521 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2522 moved to level 0 and declared as static. Also they are explicit
2523 placed in access bank. This was necessery because some times they
2524 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2525 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2526 optimizations. Currently only compare to unsigned char is implemented,
2527 * src/pic16/gen.c: added fReturnIdx array,
2528 * (struct resolvedIfx) is moved to gen.h and made public,
2529 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2530 * (aopForSym): added an optimization to directly store in stack of
2531 the operand of a SEND iCode,
2532 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2533 but as registers instead (AOP_REG) using the fReturnIdx array,
2534 * (pic16_freeAsmop): remove the freed register from the
2535 _G.sregsAlloc field,
2536 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2537 a compare of 'WREG',
2538 * (pic16_popGetTempRegCond): changed function prototype, now
2539 function takes also a bitVector argument v which holds the current
2540 set of registers that are allocated for stack access by aopForSym,
2541 registers allocated in aopForSym for accessing stack symbols are not
2542 any more part of the functions usedRegs field,
2543 * (genCall): some times aopOp is called for a stack variable to be
2544 send, aopForSym might perform the push, if this is true make sure
2545 that genCall doesn't push the variable twice by testing _G.resDirect,
2546 * (genFunction): changed testing for unspecified interrupt number
2547 from 256 to INTNO_UNSPEC,
2548 * modified selection scheme of frame pointer generation. Previously
2549 if function did use local registers a frame pointer was generated,
2550 now a frame pointer is generated only if function has arguments
2551 (that need PLUSW2 register access), or has stack arguments, or the
2552 compiler is not instructed to omit the frame pointer,
2553 * (genEndFunction): before restoring local registers that were saved
2554 in the function preamble, also restore the registers that *might*
2555 have been allocated for stack access,
2556 * (genRet): removed some old comments,
2557 * (genCmp, the active (RN's) version): added a call to the
2558 pic16_genCmp_special function to perform the compare with a more
2559 robust and optimized way,
2560 * (genInline): a feature has been added in inline code generation,
2561 which allows a wildcard variable substitution when writing inline
2562 assembly. Code is incomplete and experimental therefore undocumented,
2563 * (genCast): changed order of aopOp for result and right to allow
2564 aopForSym to directly load the result if possible,
2565 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2566 perform an optimized compare on some selected special occasions,
2567 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2568 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2569 generate an IVT any more,
2570 * src/pic16/main.c (pic16_optionsTable): added command line option
2572 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2573 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2575 * src/pic16/NOTES: Raphael Neider added in list of active developers
2576 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2577 jumptable_end to prevent bug #,
2578 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2579 inCond and outCond fields,
2580 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,

3233 Adding support for replacing ljmps with sjmps in jumptables
3234 generated for switch statements. For now you need to set the
3235 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3236 Now 4 algorithms for mcs51 jumptable generation are used:
3237 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3238 addresses loaded pc-relative for up to 112 cases and stack-pushing
3239 target addresses loaded with offset from dptr for up to 256 cases.

3269 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3271 * added libc directory. The current version of LibC contains string
3272 functions, ctype functions and macros and some functions of the
3273 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3274 be extensively tested in the future. Standard disclaimer here.
3275 Library is not automatically build yet. But one can build it by
3276 invoking 'make' inside the libc directory.

3287 * (pic16_storeForReturn): optimized return of 0,
3288 * (genCmp): experimental code for new genCmp which uses PIC18's
3289 special compare&skip instructions. Initial tests fail some times
3290 with variables grater than 1 byte in size, so new code is disabled,
3291 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3293 * (genCast): began a fix to optimize the casting of a bit to another
3294 bit, now assigning a bitfield to another bitfield will fail, sorry,

3303 and 1 for banking instruction,
3304 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3305 caused stop processing pCodes after a inline assembly block,
3306 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3308 registers when it shouldn't,
3309 * src/pic16/ralloc.c (allocReg): add preliminary support for
3310 supporting a limited set of temporary registers,
3312 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3318 (genFunction): optimize RECEIVE iCodes in reentrant functions
3320 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6320 loaded with the linker search paths (-L arguments) and the libraries
6321 to be linked with the current source (-l arguments). Changes
6322 currently will affect only the pic16 port.
6323 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6324 include path the port specific paths and port specific libraries,
6325 * gplink command now contains the $3 argument,
6326 * src/pic16/device.h,

6343 Documenting changes from previous commits.
6344 * configure.in (version 1.56),
6345 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6346 when generating output files to configure the pic16 library,
6347 but now I've commented it out, since gputils aren't installed in the
6348 SF compile farm, so library won't compile
6350 * device/lib/Makefile.in (version 1.56): initially I've added in
6351 target 'all' the prerequestive 'model-pic16' so it compiled the
6352 pic16 library, but now I've commented it out for the same reasons
6354 * added targets 'model-pic16' and 'objects-pic16' to compile the
6356 * added target 'port-specific-objects-pic16' to handle the
6357 generated libraries and copy them into the build/ directory
6358 * added target 'clean-intermediate-pic16' to clean intermediate
6359 files into pic16 directory
6360 * in target 'installdirs' added line to create directory pic16 in

6364 added lines to copy all header files to installation path,
6365 * in target 'installdirs' added line create directory for pic16
6366 headers in the installation path

6590 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
6591 how the function variable allocation summary is displayed; also
6592 include information about variables allocated to the overlay
6595 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6597 * as/mcs51/lkmain.c: Help about -Y option
6598 * as/mcs51/lkarea.c: Fixed gcc warnings
6600 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6602 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
6604 * support/valdiag/tests/overflow.c: added
6605 * src/SDCCast.c (decorateType),
6606 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6607 LEFT_OP (left shift)
6609 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6611 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6612 (default behaviour).
6614 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6616 A python script to validate compiler diagnostic messages. It can be
6617 used to verify that sdcc complains about bad c source code and
6618 gives a good location of the error.
6619 * support/valdiag/Makefile,
6620 * support/valdiag/valdiag.py,
6621 * support/valdiag/tests/*
6623 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6625 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6626 * src/SDCCsymt.c (newEnumType),
6628 * support/Util/SDCCerr.c,
6629 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6631 * support/regression/tests/enum.c: added test for enum values that
6632 require at least 2 bytes of storage.
6634 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6636 * src/common.h: added ifndef/define/endif macros
6637 around the header file.
6638 Bug reported from Jesus Calvino-Fraga
6640 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6642 * sdcc.spec: updated
6643 * device/include/Makefile.in: don't install CVS directories
6644 * device/lib/Makefile.in: added removal of CVS directories after install
6645 * doc/Makefile: fixed install, added local_icons
6646 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6647 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6648 * src/ds390/gen.c (genRightShift): fixed bug #870788
6649 * src/SDCCast.c (decorateType): fixed bug #870781
6651 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6653 PIC16 port related changes:
6654 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6655 added variable stackPos,
6657 * gen.c: genCall, assignResultValue: added support for
6658 pushing/retrieving function parameters to/from stack,
6659 genFunction,genEndFunction: setup stack frame for the
6661 genAddrOf: will be changed according to bug 863624
6663 * added files genutils.c and genutils.h which contain gen*
6664 debugged and optimised functions extracted from gen.c
6666 * glue.c: added variable 'externs' which holds extern symbols,
6667 pic16emitRegularMap: is modified to properly handle relocatable
6668 symbols under the new scheme,
6669 pic16createInterruptVect: is modified
6670 pic16printPublics: is modified to emit 'global' assembler directives,
6671 added pic16_printExterns to print extern symbols,
6672 pic16glue: initializes stack/frame pointer in the beginning of
6673 the assembly output. Temporary hack, will be corrected later,
6674 because gplink yet does not support stack and SDCC does not
6675 yet support a type of crt0.o object to create the final binary.
6677 * Removed many lines that contain 8051 legacy code.
6678 * The code is finally placed under a 'code' directive.
6679 * Added port specific options.
6681 * _process_pragma: simplified since now we do not need *special*
6682 include file to define SFR registers. But a separate header
6683 will be needed. This will be developed later.
6684 * _pic16_parseOptions: added, parses port specific options:
6685 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6686 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6687 --preplace-udata-with=
6689 * _pic16_setDefaultOptions: modified to initialize section names,
6690 but hack is temporarly out of order since it needs improvement.
6691 * _pic16_genAssemblerPreamble: configuration words are emitted by
6692 their address instead of their name. This part is incomplete and
6693 supports only the 18Fxx2 devices. Other devices will emit an error
6694 during assembly since they do not contain the same set of config
6696 * _pic16_genIVT: is modified,
6698 * pcode.c: added definitions for some hardware registers that are needed
6700 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6701 All PCI entries are updated. Now LFSR is supported.
6702 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6703 * added pic16_newpCodeOpLit2 to support instructions with
6704 two literal arguments
6705 * pic16_pCode2str: corrected code that emits assembler instructions
6706 with two literal operands and those that have an access bit modifier
6707 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6708 this fixes a bug which caused some labels to be lost, when an
6709 assembler directive was added, i.e. banksel,
6710 * pic16_FixRegisterBanking: improved logic that causes the insertion
6712 * InlineFunction: functions that are called once, are not any more
6713 inlined. This can be a port option in the future,
6715 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6717 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6718 hold the corresponding uninitialized symbols,
6719 * pic16_allocProcessorRegister: registers have explicit marked the
6721 * pic16_allocInternalRegister: registers are explicit marked as
6723 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6724 processing list, so bit registers were lost,
6727 * ralloc.h: added field 'accessBank' and original symbol operand
6728 in register definition,
6729 * removed the field isMapped from register definition,
6731 ** Several functions have been removed from various sources:
6732 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6733 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6734 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6735 pic16_assignRelocatableRegisters
6737 ** others have been introduced:
6738 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6739 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6741 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6743 * support/scripts/inc2h.pl: changed definition of BIT_AT
6744 to emit 'sbit at' instead of 'bit at'. This was a request.
6746 PIC16 port related preliminary changes:
6747 * gen.c: prefixed function popRegFromString with
6748 pic16_ and all references to it corrected
6749 * pcode.c: all pic16_pc_* hardware registers prefixed
6750 with underscore (_),
6751 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6752 * ralloc.c: newReg(): when register is REG_SFR then
6753 set address to rIdx,
6754 pic16_allocProcessorRegister(): marks register wasUsed=0
6755 pic16_writeUsedRegs(): added a call to assign processor
6756 registers via pic16_assignFixedRegisters
6758 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6760 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6761 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6762 variables in unused register banks. Also the SSEG is placed
6763 wherever there is enough space for it, and IDATA can be anywhere
6764 in internal RAM. For now compile using -Wl-Y[stack_size].
6765 The mem file is different for this option as well, since it
6766 makes no sense of talking about DSEG lenght.
6768 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6770 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6771 in certain cases, e.g. when ROM assignment, patch provided
6772 from Albert den Haan.

6917 * src/mcs51/peephole.def,
6918 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6919 (allows non-interrupt and interrupt code to safely compete for a resource

7013 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7015 * src/SDCCast.c (decorateType): disabled a transformation I added in
7016 revision 1.188 (access to fields of a structure at an absolute address);
7017 it breaks with bitfields, extern declarations, and gcse analysis.
7018 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7019 could be assigned through a pointer, so don't complain.
7020 * src/SDCCast.c (astErrors),
7022 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7659 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7660 support for standard C idiom of memory mapped variables; for
7661 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7662 to xdata int at 0x1234 tempvar = 1.
7663 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7664 provided by Akiya ISHIDA

7680 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7682 Fixed bug #621531 (const & volatile confusion in the type chain).
7683 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7684 refer to the const or volatile state of the pointer itself.

7775 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7776 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7777 fetching of the pointer
7778 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7779 copied from genNearPointerSet()
7780 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7781 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7782 If they pop r0/r1 they must be called in the opposite order than aopOp().
7783 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7784 (resp. --stack-auto), prepared for --xstack

7795 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7797 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7798 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7799 type for bits was changed. It resulted in bit variables becoming
7800 global, which is not permitted in PIC 14 assembly output.
7802 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7804 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7817 A few small changes that speed up the peephole optimizer.
7821 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7823 Try to make the peephole optimizer smarter by maintaining
7824 an association between the assembly source code and the
7825 iCodes that originated them. Put this information to use
7826 with a new peephole rule condition "notVolatile" so that
7827 the rules can be aggressive yet still safe.
7832 * src/mcs51/peeph.def
7834 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7838 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7839 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7840 if the left or right operand symbols have the accuse flag set.
7842 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7844 Changed the type of the result of the ! (NOT) operator to char;
7845 previously it returned the same type as the source. This allows
7846 us to eliminate all the genFloatNot functions (all of its target
7847 implementations were very buggy) since !float can use the same
7850 * src/SDCCicode.c (ast2iCode): ! returns char

7859 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7860 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7861 during interrupts. Ensure WSAVE is located at a shared bank address.
7862 2. Fixed page selection in some places
7863 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7864 the registers name strings.
7865 4. Fixed "signed / unsigned compare" compiler warnings.
7866 5. The PIC port manages its own allocation of the general purpose
7867 registers, but makes no attempt to reuse them. As a result when
7868 compiling it soon runs out of general purpose registers. Some
7869 additional code was added to the files pcode.c and device.c to walk
7870 through the function call tree and rename the registers so that they
7880 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7881 genPlus() & genMinus() when the result is the same as left or right

7887 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7889 Made bitfield a distinct type from bit so that bitfields
7890 convert as per ANSI C and bits retain their traditional
7891 boolean style behaviour. Implemented bitfield support in
7899 * src/ds390/gen.c: bit v bitfield split
7900 * src/z80/gen.c: New support for bitfields
7901 * support/regression/tests/bitfields.c: reenabled z80,
7904 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7906 Rules 246.x, 247.x relate to bitfields, the others speed up
7907 access to xdata mapped I/O devices.
7909 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7911 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7913 Cleaned up genPackBits and genUnpackBits and added two helper
7914 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7915 for literal assignments in genPackBits (thanks to Frieder for
7921 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7923 Fixed bug #748310 (pointer to function type mishandled when the
7924 function name is omitted). Also fixed a SIGSEGV when a function
7925 attribute (reentrant, etc) is used on a non-function or on a
7926 function but misplaced before the parameter list.
7928 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7930 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7931 * support/Util/SDCCerr.h,
7932 * support/Util/SDCCerr.c: Added func attr misuse error msg

7953 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7955 Made the constant following the "interrupt" keyword optional. If
7956 omitted, the function will not automatically be given an entry
7957 in the interrupt vector table (similar to #pragma NOIV, but
7958 less syntacticly kludgy). The interrupt number is also now
7959 range checked. Also fixed a bug in the high order bit example

7973 * src/SDCCicode.c (operandOperation): rewritten some ops
7974 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7975 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7977 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7978 be re-activated by defining REDUCE_LITERALS)
7979 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7980 unsigned, but are signed by default
7981 * src/SDCCval.c (constVal): rearranged
7982 * src/SDCCval.c (valMod): preliminary fix
7983 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8025 constants are unsigned; added recognition of "u" flag for unsigned
8026 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8027 * src/SDCCval.c (valDiv, valMod): fixed signdness
8028 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8029 signedness of modulo, left and right shift

8489 added if/endif conditional macros to remove options help
8490 messages from optionsTable when a port is not configured, added
8491 support for the PIc16 port in the ports table, when executing
8492 the compiler with no port specified on command line, a default
8493 port is selected with the new macro DEFAULT_PORT which is
8494 defined in port.h, in setDefaultOptions() linkOptions is removed
8495 from initialization assignment, since now it is a set,
8496 parseCmdLine uses setParseWithComma for linkOptions, in
8497 linkEdit() linkOptions are accessed with new function indexSet()
8498 which returns the i'th item of a set variable. See SDCCset.c, in
8499 linkEdit() when calling buildCmdLine(), added linkOptions as
8500 last argument. Now users can pass arguments to gplink via the
8501 -Wl option, main() uses pic16glue() to glue up pic16 programs

8515 gpasm complaining and test the linkage with gplink, _linkCmd and
8516 _asmCmd changed to be more gplink and gpasm friendly
8517 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8518 produced an error when parsed, peep rule 12 is added to utilize
8519 movff, but it is commented out since the pCode does not support
8520 yet a command with 2 address arguments
8522 2003-05-18 <johan AT balder>
8524 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8551 2003-05-11 Borut Razem <borut.razem AT siol.net>
8553 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9539 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9540 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9542 2003-01-07 <johan AT balder>
9544 * src/SDCCast.c (decorateType): fixed bug #600035
9546 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9547 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9557 2003-01-06 <johan AT balder>
9559 * src/SDCCicode.c: fixed array add
9561 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9562 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9563 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9565 2003-01-04 <johan AT balder>
9567 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9569 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9570 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9572 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9573 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9574 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9576 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9577 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9579 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9580 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9582 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9583 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9585 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9587 * in \sdcc\as\mcs51\ changed these files in order to create an
9588 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9589 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9590 following files to include the previous two files: aslink.dsp,
9591 Makefile.aslink, Makefile.bcc, and Makefile.in.
9593 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9594 .adb instead of .cdb
9596 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9598 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9599 value from option --iram-size.
9601 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9603 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9606 2002-09-18 <wiml AT hhhh.org>
9608 * SDCClrange.h: exposed setFromRange() and setToRange()
9609 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9610 packRegsForAccUse() (bug 542397)
9611 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9612 multiple times and emitting the fetch operations more than once
9613 added aopGetUsesAcc() function to allow binary operators to
9614 fetch their operands in the correct order; made genMinus() emit
9615 compact code for X = LITERAL - Y
9617 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9618 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9619 sprintf() in line 1267.
9621 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9622 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9625 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9626 Changes to aslink (All the changes are marked with 'JCF'):
9628 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9631 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9632 area BSEG. Also moves, if possible, the DATA area down into the internal
9633 ram so more space is available.
9635 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9638 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9639 not bytes. Function summary() which creates a memory usage summary
9640 file with extension .mem. Reports of overlaping stack and small stack
9641 size. If the space for the stack is less than 16 bytes aslink trows a
9644 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9645 the 8051. Option 'y' for memory summary output file.
9647 Changes to sdcc (All the changes are marked with 'JCF'):
9649 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9651 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9652 overlaying area for it (uses RegBankUsed[4]).
9654 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9655 bank zero as used by default. By default aslink locates the stack
9656 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9657 the creation of the .mem file. Delegates the allocation of data area
9658 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9659 the begining of the stack area to aslink.
9661 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9662 glue() in SDCCglue.c creates an area for it.
9664 2002-09-03 Borut Razem <borut.razem AT siol.net>
9665 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9666 sdcc/src/pic/glue.c:
9667 introduced atexit() handler for teporay files removal in case of
9668 errors, assertions, ...
9670 2002-08-29 Borut Razem <borut.razem AT siol.net>
9671 * sdcc/support/cpp2/auto-host_vc_in.h:
9672 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9673 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9674 Maybe there is a similar problem with BORLANDC? It should be checked!
9676 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9677 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9678 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9679 was not executed, and the compiler (cl) launched a warning:
9680 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9682 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9683 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9685 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9686 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9688 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9689 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9690 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9691 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9692 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9693 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9694 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9695 - added Release configuration in VS projects
9696 - review of compiler an linker options
9697 - VC .exe files are generated in bin_vc directory, not to interfere
9698 with binaries generated from other projects (cygwin, mingw, bcc ...)
9700 * sdcc/src/yacc.dsp: added
9702 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9703 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9704 and insert the version number definitions from .version
9706 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9708 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9709 added - genarate auto-host.h using auto-host_vc_in.h as template
9712 removed from CVS, generated automatically
9714 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9715 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9717 2002-08-11 Borut Razem <borut.razem AT siol.net>
9718 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9720 2002-08-10 Borut Razem <borut.razem AT siol.net>
9721 * src/SDCCmain.c (main):
9722 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9723 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9724 The consequence was that some temporary files were not removed.
9727 unification of code in functions tempfilename() and tempfile():
9728 function tempnam() is defined in Visual Studio 6.0 and .NET
9730 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9732 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9733 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9734 - removed compiler command line option /WX: Treats all warnings as errors
9735 - update a list of source files, included into the project
9737 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9738 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9739 changed project type to Generic Project so that can be correcly converted to VS.NET project
9741 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9743 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9745 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9747 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9748 added return 0 statements after assert() to make compiler happy
9750 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9751 added newline in the def file to keep MSC compiler satisfied
9753 * sdcc/src/z80/gen.c:
9754 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9755 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9756 - solved MSC error in function aopDump()
9758 * sdcc_vc.h: define PREFIX as "\\sdcc"
9760 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9761 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9763 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9764 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9765 - Rewrote the register banking algorithm.
9766 - Added pCode live-range analysis to registers (for now, only non-used and
9767 singly-used registers optimized away)
9769 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9771 * 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.
9773 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9774 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9776 2002-04-22 Michael Hope <michaelh AT vroom>

9796 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9798 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9800 2002-03-28 Johan Knol <johan AT balder>
9802 * src/SDCCval.c: fixed bug #532436
9804 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9806 Added "char *Processor" field to the port structure.
9809 Added -p option. Allows port dependent processor to be specified.
9812 Initialized the new field char *Processor field to NULL in all ports
9815 Compiler generated registers for interrupt context saving
9816 were not getting allocated.
9818 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9821 Fixed left shift. Will promote the left side of a left shift
9822 if a) left shifting more than size of operand or b) when assigned
9823 to something size > size of left side
9825 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9827 tons of changes. Register allocation has been
9828 rewritten. Added customization for the various PICs. Flow
9829 analysis is restructured. ...
9835 Added. device.c is a PIC port hack to accomodate variations
9838 2002-03-13 Michael Hope <michaelh AT vroom>
9840 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9842 2002-03-04 johanknol <johanknol AT manik>
9844 * /src/SDCCval.c: fixed
9846 const unsigned char arr[][2] = { { 0, 1 } };
9847 t18.c:1: error: Initializer element is not constant
9849 2002-03-04 bela <bela AT manik>
9851 * /device/include/mcs51reg.h:
9852 ds89c420 register definition update
9854 2002-03-03 <johan AT FRIJA>

9933 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9935 * sdcc/src/SDCCloop.c:
9936 Previous fix was not good. basic blocks that have "break" or "return" are
9937 not really partof a loop , but live ranges used in these blocks should
9938 be live thru the entire loop, so set partOfLoop but don't add them to
9941 2002-02-21 <johan AT FRIJA>
9943 * src/SDCCcse.c: fixed bug #514308
9945 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9948 Fixed BUG #519583. If a conditional block ended in a return/break
9949 statement inside a loop, it was not being considered part of the loop.
9951 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9953 2002-02-10 Karl Bongers <karl AT turbobit.com>
9956 Fixed up SDCDB debugger somewhat. Updated debugger/README
9957 with lots of comments and notes.
9959 * device/examples/test2.c:
9960 Fix bug, "red" variable not being initialized(compiler complained).
9962 * device/examples/Makefile, examples/test3.c:
9963 Add Makefile in device/examples folder, compiles test3.c
9964 for use as a multiple module SDCDB test case.
9966 * sim/ucsim/cmd.src/cmdset.cc:
9967 Took out debug printfs in ucsim "next" command.
9970 Karl and Johan start ucsim XA support. Most dissassembly working,
9971 about 75% emulation done(plenty of work remaining).
9973 * sim/ucsim/z80.src:
9974 Add Z80 support to ucsim, add test-ucz80 regression test,
9975 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9976 Notice z80 compiler fails on examples/test3.c/crc code.
9978 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9980 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
9981 Added support for --parms-in-bank1
9983 * src/ds390/peeph.def:
9984 added a few more peephole optimzations
9987 1) added __builtin_inp & __builtin_outp used to read in data of given length
9988 from a memory mapped port
9989 2) added __builtin_memcmp
9990 3) added __builtin_swapw swap bytes of a short
9992 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9993 1) handle multiple send & receives from register bank1
9994 2) ralloc can now allocate DPTR1 to some liveRanges
9996 * src/SDCCsymt.c, src/SDCCsymt.h:
9997 changes to handle multiple sends & receives
10000 added some pointer arithmetic optimization
10002 * src/SDCCptropt.c:
10003 added some pointer arithmetic optimizations but not stable yet so not
10004 called from anywhere (will get this working shortly)
10006 * src/SDCCopt.c: fixed for multiple sends & receives
10009 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
10010 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
10011 set preprocessor defines (depending on options)
