673 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
675 Enabled VPATH feature: changed nearly all Makefiles (149 files).
676 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
678 One basic decision: e.g. src/clean.mk includes further files. In order
679 to make this work there are two solutions:
680 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
681 run configure on them. This way they can use
682 'include $(srcdir)/port-clean.mk'
683 - always include clean.mk by the Makefile at the same level. To avoid
684 that `make clean` tries to include and build Makefile.dep the
685 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
686 implemented, because now even `make uninstall` doesn't create
687 Makefile.in. clean.mk could be eliminated by pasting it in
690 * debugger/mcs51/Makefile.in: build own objects from library sources
691 (SLIB, SDCC) in current directory
693 * configure, configure.in: renamed --disable-device-lib-build in
694 --disable-device-lib; added --enable-doc, the required tools are
695 searched by configure; added result message; the toolchain for the
696 belonging ports are now only built, if the port is enabled.
698 * support/regression/*: all output is written in directory gen, because
699 the fwk and ports directories don't livet in the build tree using vpath
701 * doc/sdccman.lyx: renamed --disable-device-lib-build to
702 --disable-device-lib, added --enable-doc, added section VPATH
704 * sim/ucsim/configure.in,
705 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
706 z80 are enabled by default
708 2006-04-24 Raphael Neider <rneider AT web.de>
710 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
711 to config word, "pic14_"-prefixed some extern functions
712 (pic14_emitConfigWord): emit __config directive(s) if assignment to
713 config word has been found
714 * src/pic/device.h: added prototypes
715 * src/pic/pcode.c: added "pic14_"-prefix where needed

718 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

965 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
967 * src/SDCCpeeph.c (operandsLiteral): new, added,
968 (callFuncByName): inserted operandsLiteral

978 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
979 implemented patch 1120823 Thanks to Willy De la Court (normal
980 interrupts need an interrupt number now if they are made critical),
981 and enabled nesting of critical functions though not for gbz80
982 (genCritical, genEndCritical): added functions
983 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
984 * src/z80/mappings.i: added "ei" to all mappings
986 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

989 submitted by the Debian SDCC maintainer Aurelien Jarno:
990 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
991 archive with gcc 4.1 on mips and wrote the patch"
993 2006-03-16 Raphael Neider <rneider AT web.de>
995 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
996 the left operand is shorter than the result (c* = lit-c* + int),
998 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1001 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1003 * src/.version: increased version number to 2.5.5
1004 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1005 linking is done manually in pic16 port's _linkEdit,
1006 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1007 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1008 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1009 allocate asmop as AOP_ACC,
1010 (aopForRemat): added parameter 'bool result' in function declaration,
1011 (pic16_aopGet): return AOP_ACC when accessing WREG,
1012 (pic16_popGetTempReg): minor modification,
1013 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1014 'pic16_allocWithIdx',
1015 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1016 calling function in absolute addresses,
1017 (genAssign): take into account AOP_ACC asmop,
1018 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1019 * src/pic16/pcoderegs.c: some debug functions and lines added,
1020 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1021 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1023 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1024 call to allocReg, not by manually allocating a new one,
1025 (pic16_assignRegisters): now before going through the register
1026 allocating functions mark all registers as free. This eliminates some
1027 side effects resulting from peephole parser done earlier in the backbone
1029 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1031 * src/SDCCicode.c (geniCodeLogic),

1050 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1051 (aopForSym, aopOp): increment asmop.allocated if reused,
1052 (freeAsmop): decrement asmop.allocated and check for zero instead of
1054 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1055 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1056 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1079 2006-03-06 Borut Razem <borut.razem AT siol.net>
1081 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1082 made the linker quiet
1084 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1086 * src/pic16/gen.c (genPcall): fixed bug #1443644
1087 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1088 which dumps before the function entry point a data byte which represents
1089 the number of the local variables used by the specified function, added
1090 'xinst' for initial support for Extended Instruction Support,
1091 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1092 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1093 port->fun_prefix anymore (may change later),
1094 (genFunction, genEndFunction): do not store/restore local registers for
1095 _main (this should take care the --main-return command line option in
1097 (genOr): removed some legacy pic-port instructions,
1098 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1099 performing operations with SFR's causes data to be written more than
1100 once to each SFR. Perhaps SFRs should be handled in special cases...
1101 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1103 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1104 into account for stack starting position,
1105 (struct OPTIONS pic16_optionsTable): added command line argument
1106 --extended or -y for Extended Instruction Support,
1107 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1108 (deassignLRs): *** perhaps the most important change, old 'for' code
1109 (commented out for reference), didn't account for some registers which
1110 were left marked 'not free' after a pointer operation. The change
1111 reduces register usage a lot in some cases
1113 2006-03-04 Borut Razem <borut.razem AT siol.net>
1115 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3486 moved to level 0 and declared as static. Also they are explicit
3487 placed in access bank. This was necessery because some times they
3488 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3489 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3490 optimizations. Currently only compare to unsigned char is implemented,
3491 * src/pic16/gen.c: added fReturnIdx array,
3492 * (struct resolvedIfx) is moved to gen.h and made public,
3493 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3494 * (aopForSym): added an optimization to directly store in stack of
3495 the operand of a SEND iCode,
3496 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3497 but as registers instead (AOP_REG) using the fReturnIdx array,
3498 * (pic16_freeAsmop): remove the freed register from the
3499 _G.sregsAlloc field,
3500 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3501 a compare of 'WREG',
3502 * (pic16_popGetTempRegCond): changed function prototype, now
3503 function takes also a bitVector argument v which holds the current
3504 set of registers that are allocated for stack access by aopForSym,
3505 registers allocated in aopForSym for accessing stack symbols are not
3506 any more part of the functions usedRegs field,
3507 * (genCall): some times aopOp is called for a stack variable to be
3508 send, aopForSym might perform the push, if this is true make sure
3509 that genCall doesn't push the variable twice by testing _G.resDirect,
3510 * (genFunction): changed testing for unspecified interrupt number
3511 from 256 to INTNO_UNSPEC,
3512 * modified selection scheme of frame pointer generation. Previously
3513 if function did use local registers a frame pointer was generated,
3514 now a frame pointer is generated only if function has arguments
3515 (that need PLUSW2 register access), or has stack arguments, or the
3516 compiler is not instructed to omit the frame pointer,
3517 * (genEndFunction): before restoring local registers that were saved
3518 in the function preamble, also restore the registers that *might*
3519 have been allocated for stack access,
3520 * (genRet): removed some old comments,
3521 * (genCmp, the active (RN's) version): added a call to the
3522 pic16_genCmp_special function to perform the compare with a more
3523 robust and optimized way,
3524 * (genInline): a feature has been added in inline code generation,
3525 which allows a wildcard variable substitution when writing inline
3526 assembly. Code is incomplete and experimental therefore undocumented,
3527 * (genCast): changed order of aopOp for result and right to allow
3528 aopForSym to directly load the result if possible,
3529 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3530 perform an optimized compare on some selected special occasions,
3531 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3532 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3533 generate an IVT any more,
3534 * src/pic16/main.c (pic16_optionsTable): added command line option
3536 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3537 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3539 * src/pic16/NOTES: Raphael Neider added in list of active developers
3540 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3541 jumptable_end to prevent bug #,
3542 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3543 inCond and outCond fields,
3544 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3545 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3546 turn off register spilling,
3547 * (packRegsForOneUse): synced with other ports' versions although it
3548 is not used currently,
3549 * (pic16_packRegisters): added an optimization while reading
3550 structure bitfields, some registers may be saved (malloc code is
3551 decreased by 80 bytes)
3553 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3555 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3556 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3557 this can be optimized more?
3559 2005-03-10 Raphael Neider <rneider AT web.de>
3561 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3562 genNearPointerGet): (hopefully) fixed access to bitfields via
3563 pointers (p->bitN = x; and x = p->bitN; failed)

3889 access stack and frame pointers. They are initially assigned to
3890 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3891 accessing SFRs. Updated all occurences of modification of stack or
3892 frame pointer in gen.c and pcode.c,

4198 generated for switch statements. For now you need to set the
4199 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4200 Now 4 algorithms for mcs51 jumptable generation are used:
4201 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4235 * added libc directory. The current version of LibC contains string
4236 functions, ctype functions and macros and some functions of the
4237 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4238 be extensively tested in the future. Standard disclaimer here.

4252 * (genCmp): experimental code for new genCmp which uses PIC18's
4253 special compare&skip instructions. Initial tests fail some times
4254 with variables grater than 1 byte in size, so new code is disabled,
4255 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4257 * (genCast): began a fix to optimize the casting of a bit to another
4258 bit, now assigning a bitfield to another bitfield will fail, sorry,

4272 registers when it shouldn't,
4273 * src/pic16/ralloc.c (allocReg): add preliminary support for
4274 supporting a limited set of temporary registers,
4276 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7281 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7283 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7284 loaded with the linker search paths (-L arguments) and the libraries
7285 to be linked with the current source (-l arguments). Changes
7286 currently will affect only the pic16 port.
7287 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7288 include path the port specific paths and port specific libraries,
7289 * gplink command now contains the $3 argument,
7290 * src/pic16/device.h,
7291 * src/pic16/device.c,: structure PIC_device is made public and
7292 renamed to PIC16_device, the same for variable Pics which is renamed

7307 Documenting changes from previous commits.
7308 * configure.in (version 1.56),
7309 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7310 when generating output files to configure the pic16 library,
7311 but now I've commented it out, since gputils aren't installed in the
7312 SF compile farm, so library won't compile
7314 * device/lib/Makefile.in (version 1.56): initially I've added in
7315 target 'all' the prerequestive 'model-pic16' so it compiled the
7316 pic16 library, but now I've commented it out for the same reasons
7318 * added targets 'model-pic16' and 'objects-pic16' to compile the
7320 * added target 'port-specific-objects-pic16' to handle the
7321 generated libraries and copy them into the build/ directory
7322 * added target 'clean-intermediate-pic16' to clean intermediate
7323 files into pic16 directory
7324 * in target 'installdirs' added line to create directory pic16 in

7345 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7346 option so that it actually works. Made it specific to the z80, since
7347 the gbz80 doesn't have these kinds of I/O ports.
7349 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7351 * device/include/z180.h,

7375 via literal number. The symbol is placed in the corresponding
7376 position of the data ram
7377 * (pic16_dump_section): relocatable and absolute uninitialized
7378 data are now emitted in sorted order to reduce section naming,
7379 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7380 weren't marked as being in the access bank,
7382 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7384 Added portion of GNU PIC Library under the directory
7385 device/include/pic16 and device/lib/pic16. These files
7386 contain the declarations of SFRs for the PIC18Fxx2 devices.
7387 The directory is initialized via configure from toplevel.
7389 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7391 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7417 all over. Telling LaTeX to be less strict with word spacing
7418 to better keep the right margin. Changed some notes about
7419 maintainance of the ports in section 3.2.1 - is it OK like this?
7421 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7423 SDCC source changes:
7424 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
7425 convilong): modified to inform the pic16 port that builtin functions
7428 PIC16 PORT specific changes:
7429 * src/pic16/device.c pic16_dump_equates() added,
7430 processor registers declared internally by the port are emitted in
7431 the translation as equates,
7432 * src/pic16/gen.c: inline code is passed unprocessed to the
7434 * (pic16_popGetLit2): fnuction modified to take second operand as
7435 pCodeOp pointer and not as literal,
7436 * (popRegFromIdx): prefixed with pic16_,

7439 * (pic16_pushpCodeOpReg, pic16_poppCodeOpReg): added
7440 * (genFunction): initializes local stack frame and pushes on stack
7441 all the registers used by this function,
7442 * (genEndFunction): restores all registers from stack and restores
7444 * src/pic16/glue.c (pic16emitRegularMap): various changes and
7446 * (pic16glue): changed the program startup sequence,

7458 UPPER for immediate operands,
7459 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7461 * src/pic16/peeph.def: all peepholes with movff are commented out,
7462 because there is a problem in the pcode peep optimizer,

7573 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7575 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7576 (default behaviour).
7578 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7580 A python script to validate compiler diagnostic messages. It can be
7581 used to verify that sdcc complains about bad c source code and
7582 gives a good location of the error.
7583 * support/valdiag/Makefile,
7584 * support/valdiag/valdiag.py,
7585 * support/valdiag/tests/*

7602 Bug reported from Jesus Calvino-Fraga
7604 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7606 * sdcc.spec: updated
7607 * device/include/Makefile.in: don't install CVS directories
7608 * device/lib/Makefile.in: added removal of CVS directories after install
7609 * doc/Makefile: fixed install, added local_icons
7610 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7611 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7612 * src/ds390/gen.c (genRightShift): fixed bug #870788
7613 * src/SDCCast.c (decorateType): fixed bug #870781
7615 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7617 PIC16 port related changes:
7618 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7619 added variable stackPos,
7621 * gen.c: genCall, assignResultValue: added support for
7622 pushing/retrieving function parameters to/from stack,
7623 genFunction,genEndFunction: setup stack frame for the
7625 genAddrOf: will be changed according to bug 863624
7627 * added files genutils.c and genutils.h which contain gen*
7628 debugged and optimised functions extracted from gen.c
7630 * glue.c: added variable 'externs' which holds extern symbols,
7631 pic16emitRegularMap: is modified to properly handle relocatable
7632 symbols under the new scheme,
7633 pic16createInterruptVect: is modified
7634 pic16printPublics: is modified to emit 'global' assembler directives,
7635 added pic16_printExterns to print extern symbols,
7636 pic16glue: initializes stack/frame pointer in the beginning of
7637 the assembly output. Temporary hack, will be corrected later,
7638 because gplink yet does not support stack and SDCC does not
7639 yet support a type of crt0.o object to create the final binary.
7641 * Removed many lines that contain 8051 legacy code.
7642 * The code is finally placed under a 'code' directive.
7643 * Added port specific options.
7645 * _process_pragma: simplified since now we do not need *special*
7646 include file to define SFR registers. But a separate header
7647 will be needed. This will be developed later.
7648 * _pic16_parseOptions: added, parses port specific options:
7649 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7650 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7651 --preplace-udata-with=
7653 * _pic16_setDefaultOptions: modified to initialize section names,
7654 but hack is temporarly out of order since it needs improvement.
7655 * _pic16_genAssemblerPreamble: configuration words are emitted by
7656 their address instead of their name. This part is incomplete and
7657 supports only the 18Fxx2 devices. Other devices will emit an error
7658 during assembly since they do not contain the same set of config
7660 * _pic16_genIVT: is modified,
7662 * pcode.c: added definitions for some hardware registers that are needed
7664 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7665 All PCI entries are updated. Now LFSR is supported.
7666 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7667 * added pic16_newpCodeOpLit2 to support instructions with
7668 two literal arguments
7669 * pic16_pCode2str: corrected code that emits assembler instructions
7670 with two literal operands and those that have an access bit modifier
7671 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7672 this fixes a bug which caused some labels to be lost, when an
7673 assembler directive was added, i.e. banksel,
7674 * pic16_FixRegisterBanking: improved logic that causes the insertion
7676 * InlineFunction: functions that are called once, are not any more
7677 inlined. This can be a port option in the future,
7679 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7681 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7682 hold the corresponding uninitialized symbols,
7683 * pic16_allocProcessorRegister: registers have explicit marked the
7685 * pic16_allocInternalRegister: registers are explicit marked as
7687 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7688 processing list, so bit registers were lost,
7691 * ralloc.h: added field 'accessBank' and original symbol operand
7692 in register definition,
7693 * removed the field isMapped from register definition,
7695 ** Several functions have been removed from various sources:
7696 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7697 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7698 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7699 pic16_assignRelocatableRegisters
7701 ** others have been introduced:
7702 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7703 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7705 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7707 * support/scripts/inc2h.pl: changed definition of BIT_AT
7708 to emit 'sbit at' instead of 'bit at'. This was a request.
7710 PIC16 port related preliminary changes:
7711 * gen.c: prefixed function popRegFromString with
7712 pic16_ and all references to it corrected
7713 * pcode.c: all pic16_pc_* hardware registers prefixed
7714 with underscore (_),
7715 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7716 * ralloc.c: newReg(): when register is REG_SFR then
7717 set address to rIdx,
7718 pic16_allocProcessorRegister(): marks register wasUsed=0
7719 pic16_writeUsedRegs(): added a call to assign processor
7720 registers via pic16_assignFixedRegisters
7722 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7724 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7725 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7726 variables in unused register banks. Also the SSEG is placed
7727 wherever there is enough space for it, and IDATA can be anywhere
7728 in internal RAM. For now compile using -Wl-Y[stack_size].
7729 The mem file is different for this option as well, since it
7730 makes no sense of talking about DSEG lenght.
7732 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7734 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7735 in certain cases, e.g. when ROM assignment, patch provided
7736 from Albert den Haan.
7738 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8740 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8741 fetching of the pointer
8742 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8743 copied from genNearPointerSet()
8744 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8745 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8761 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8762 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8763 type for bits was changed. It resulted in bit variables becoming
8764 global, which is not permitted in PIC 14 assembly output.
8766 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8768 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8781 A few small changes that speed up the peephole optimizer.
8785 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8787 Try to make the peephole optimizer smarter by maintaining
8788 an association between the assembly source code and the
8789 iCodes that originated them. Put this information to use
8790 with a new peephole rule condition "notVolatile" so that
8791 the rules can be aggressive yet still safe.
8796 * src/mcs51/peeph.def
8798 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8802 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8803 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8804 if the left or right operand symbols have the accuse flag set.
8806 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8808 Changed the type of the result of the ! (NOT) operator to char;
8809 previously it returned the same type as the source. This allows
8810 us to eliminate all the genFloatNot functions (all of its target
8811 implementations were very buggy) since !float can use the same
8814 * src/SDCCicode.c (ast2iCode): ! returns char

8823 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8824 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8825 during interrupts. Ensure WSAVE is located at a shared bank address.
8826 2. Fixed page selection in some places
8827 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8828 the registers name strings.
8829 4. Fixed "signed / unsigned compare" compiler warnings.
8830 5. The PIC port manages its own allocation of the general purpose
8831 registers, but makes no attempt to reuse them. As a result when
8832 compiling it soon runs out of general purpose registers. Some
8833 additional code was added to the files pcode.c and device.c to walk
8834 through the function call tree and rename the registers so that they
8844 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8845 genPlus() & genMinus() when the result is the same as left or right

8851 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8853 Made bitfield a distinct type from bit so that bitfields
8854 convert as per ANSI C and bits retain their traditional
8855 boolean style behaviour. Implemented bitfield support in
8863 * src/ds390/gen.c: bit v bitfield split
8864 * src/z80/gen.c: New support for bitfields
8865 * support/regression/tests/bitfields.c: reenabled z80,
8868 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8870 Rules 246.x, 247.x relate to bitfields, the others speed up
8871 access to xdata mapped I/O devices.
8873 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8875 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8877 Cleaned up genPackBits and genUnpackBits and added two helper
8878 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8879 for literal assignments in genPackBits (thanks to Frieder for
8885 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8887 Fixed bug #748310 (pointer to function type mishandled when the
8888 function name is omitted). Also fixed a SIGSEGV when a function
8889 attribute (reentrant, etc) is used on a non-function or on a
8890 function but misplaced before the parameter list.
8892 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8894 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8895 * support/Util/SDCCerr.h,

8917 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8919 Made the constant following the "interrupt" keyword optional. If
8920 omitted, the function will not automatically be given an entry
8921 in the interrupt vector table (similar to #pragma NOIV, but
8922 less syntacticly kludgy). The interrupt number is also now
8923 range checked. Also fixed a bug in the high order bit example

8939 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8941 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8942 be re-activated by defining REDUCE_LITERALS)
8943 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8944 unsigned, but are signed by default
8945 * src/SDCCval.c (constVal): rearranged
8946 * src/SDCCval.c (valMod): preliminary fix
8947 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9453 added if/endif conditional macros to remove options help
9454 messages from optionsTable when a port is not configured, added
9455 support for the PIc16 port in the ports table, when executing
9456 the compiler with no port specified on command line, a default
9457 port is selected with the new macro DEFAULT_PORT which is
9458 defined in port.h, in setDefaultOptions() linkOptions is removed
9459 from initialization assignment, since now it is a set,
9460 parseCmdLine uses setParseWithComma for linkOptions, in
9461 linkEdit() linkOptions are accessed with new function indexSet()
9462 which returns the i'th item of a set variable. See SDCCset.c, in
9463 linkEdit() when calling buildCmdLine(), added linkOptions as
9464 last argument. Now users can pass arguments to gplink via the
9465 -Wl option, main() uses pic16glue() to glue up pic16 programs

9479 gpasm complaining and test the linkage with gplink, _linkCmd and
9480 _asmCmd changed to be more gplink and gpasm friendly
9481 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9482 produced an error when parsed, peep rule 12 is added to utilize
9483 movff, but it is commented out since the pCode does not support
9484 yet a command with 2 address arguments
9486 2003-05-18 <johan AT balder>
9488 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9511 2003-05-12 Borut Razem <borut.razem AT siol.net>
9513 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9515 2003-05-11 Borut Razem <borut.razem AT siol.net>
9517 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9518 the path of bin directory, so that PATH is the only env. variable, which has to be set

10547 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10549 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10551 * in \sdcc\as\mcs51\ changed these files in order to create an
10552 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10553 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10554 following files to include the previous two files: aslink.dsp,
10555 Makefile.aslink, Makefile.bcc, and Makefile.in.
10557 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10558 .adb instead of .cdb
10560 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10562 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10563 value from option --iram-size.
10565 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10567 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10570 2002-09-18 <wiml AT hhhh.org>
10572 * SDCClrange.h: exposed setFromRange() and setToRange()
10573 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10574 packRegsForAccUse() (bug 542397)
10575 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10576 multiple times and emitting the fetch operations more than once
10577 added aopGetUsesAcc() function to allow binary operators to
10578 fetch their operands in the correct order; made genMinus() emit
10579 compact code for X = LITERAL - Y
10581 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10582 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10583 sprintf() in line 1267.
10585 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10586 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10589 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10590 Changes to aslink (All the changes are marked with 'JCF'):
10592 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10595 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10596 area BSEG. Also moves, if possible, the DATA area down into the internal
10597 ram so more space is available.
10599 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10602 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10603 not bytes. Function summary() which creates a memory usage summary
10604 file with extension .mem. Reports of overlaping stack and small stack
10605 size. If the space for the stack is less than 16 bytes aslink trows a
10608 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10609 the 8051. Option 'y' for memory summary output file.
10611 Changes to sdcc (All the changes are marked with 'JCF'):
10613 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10615 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10616 overlaying area for it (uses RegBankUsed[4]).
10618 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10619 bank zero as used by default. By default aslink locates the stack
10620 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10621 the creation of the .mem file. Delegates the allocation of data area
10622 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10623 the begining of the stack area to aslink.
10625 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10626 glue() in SDCCglue.c creates an area for it.
10628 2002-09-03 Borut Razem <borut.razem AT siol.net>
10629 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10630 sdcc/src/pic/glue.c:
10631 introduced atexit() handler for teporay files removal in case of
10632 errors, assertions, ...
10634 2002-08-29 Borut Razem <borut.razem AT siol.net>
10635 * sdcc/support/cpp2/auto-host_vc_in.h:
10636 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10637 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10638 Maybe there is a similar problem with BORLANDC? It should be checked!
10640 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10641 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10642 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10643 was not executed, and the compiler (cl) launched a warning:
10644 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10646 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10647 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10649 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10650 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10652 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10653 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10654 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10655 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10656 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10657 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10658 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10659 - added Release configuration in VS projects
10660 - review of compiler an linker options
10661 - VC .exe files are generated in bin_vc directory, not to interfere
10662 with binaries generated from other projects (cygwin, mingw, bcc ...)
10664 * sdcc/src/yacc.dsp: added
10666 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10667 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10668 and insert the version number definitions from .version
10670 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10672 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10673 added - genarate auto-host.h using auto-host_vc_in.h as template
10676 removed from CVS, generated automatically
10678 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10679 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10681 2002-08-11 Borut Razem <borut.razem AT siol.net>
10682 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10684 2002-08-10 Borut Razem <borut.razem AT siol.net>
10685 * src/SDCCmain.c (main):
10686 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10687 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10688 The consequence was that some temporary files were not removed.
10691 unification of code in functions tempfilename() and tempfile():
10692 function tempnam() is defined in Visual Studio 6.0 and .NET
10694 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10696 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10697 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10698 - removed compiler command line option /WX: Treats all warnings as errors
10699 - update a list of source files, included into the project
10701 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10702 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10703 changed project type to Generic Project so that can be correcly converted to VS.NET project
10705 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10707 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10709 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10711 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10712 added return 0 statements after assert() to make compiler happy
10714 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10715 added newline in the def file to keep MSC compiler satisfied
10717 * sdcc/src/z80/gen.c:
10718 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10719 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10720 - solved MSC error in function aopDump()
10722 * sdcc_vc.h: define PREFIX as "\\sdcc"
10724 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10725 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10728 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10729 - Rewrote the register banking algorithm.
10730 - Added pCode live-range analysis to registers (for now, only non-used and
10731 singly-used registers optimized away)
10733 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10735 * 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.

10762 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10764 2002-03-28 Johan Knol <johan AT balder>
10766 * src/SDCCval.c: fixed bug #532436
10768 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10770 Added "char *Processor" field to the port structure.
10773 Added -p option. Allows port dependent processor to be specified.
10776 Initialized the new field char *Processor field to NULL in all ports
10779 Compiler generated registers for interrupt context saving
10780 were not getting allocated.
10782 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10785 Fixed left shift. Will promote the left side of a left shift
10786 if a) left shifting more than size of operand or b) when assigned
10787 to something size > size of left side
10789 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10791 tons of changes. Register allocation has been
10792 rewritten. Added customization for the various PICs. Flow
10793 analysis is restructured. ...
10795 * src/pic/device.h:
10798 * src/pic/device.c:
10799 Added. device.c is a PIC port hack to accomodate variations
10802 2002-03-13 Michael Hope <michaelh AT vroom>
10804 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10806 2002-03-04 johanknol <johanknol AT manik>
10808 * /src/SDCCval.c: fixed
10810 const unsigned char arr[][2] = { { 0, 1 } };
10811 t18.c:1: error: Initializer element is not constant
10813 2002-03-04 bela <bela AT manik>
