672 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
674 Enabled VPATH feature: changed nearly all Makefiles (149 files).
675 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
677 One basic decision: e.g. src/clean.mk includes further files. In order
678 to make this work there are two solutions:
679 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
680 run configure on them. This way they can use
681 'include $(srcdir)/port-clean.mk'
682 - always include clean.mk by the Makefile at the same level. To avoid
683 that `make clean` tries to include and build Makefile.dep the
684 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
685 implemented, because now even `make uninstall` doesn't create
686 Makefile.in. clean.mk could be eliminated by pasting it in
689 * debugger/mcs51/Makefile.in: build own objects from library sources
690 (SLIB, SDCC) in current directory
692 * configure, configure.in: renamed --disable-device-lib-build in
693 --disable-device-lib; added --enable-doc, the required tools are
694 searched by configure; added result message; the toolchain for the
695 belonging ports are now only built, if the port is enabled.
697 * support/regression/*: all output is written in directory gen, because
698 the fwk and ports directories don't livet in the build tree using vpath
700 * doc/sdccman.lyx: renamed --disable-device-lib-build to
701 --disable-device-lib, added --enable-doc, added section VPATH
703 * sim/ucsim/configure.in,
704 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
705 z80 are enabled by default
707 2006-04-24 Raphael Neider <rneider AT web.de>
709 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
710 to config word, "pic14_"-prefixed some extern functions
711 (pic14_emitConfigWord): emit __config directive(s) if assignment to
712 config word has been found
713 * src/pic/device.h: added prototypes
714 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

949 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
951 * src/SDCCpeeph.c (initPeepHole): implemented RFE 1460196, when both

959 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
961 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest
962 changes seem to cause (trigger?) problems with the build system.
964 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
966 * src/SDCCpeeph.c (operandsLiteral): new, added,
967 (callFuncByName): inserted operandsLiteral

977 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
978 implemented patch 1120823 Thanks to Willy De la Court (normal
979 interrupts need an interrupt number now if they are made critical),
980 and enabled nesting of critical functions though not for gbz80
981 (genCritical, genEndCritical): added functions
982 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
983 * src/z80/mappings.i: added "ei" to all mappings
985 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

988 submitted by the Debian SDCC maintainer Aurelien Jarno:
989 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
990 archive with gcc 4.1 on mips and wrote the patch"
992 2006-03-16 Raphael Neider <rneider AT web.de>
994 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
995 the left operand is shorter than the result (c* = lit-c* + int),
997 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1000 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1002 * src/.version: increased version number to 2.5.5
1003 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1004 linking is done manually in pic16 port's _linkEdit,
1005 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1006 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1007 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1008 allocate asmop as AOP_ACC,
1009 (aopForRemat): added parameter 'bool result' in function declaration,
1010 (pic16_aopGet): return AOP_ACC when accessing WREG,
1011 (pic16_popGetTempReg): minor modification,
1012 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1013 'pic16_allocWithIdx',
1014 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1015 calling function in absolute addresses,
1016 (genAssign): take into account AOP_ACC asmop,
1017 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1018 * src/pic16/pcoderegs.c: some debug functions and lines added,
1019 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1020 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1022 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1023 call to allocReg, not by manually allocating a new one,
1024 (pic16_assignRegisters): now before going through the register
1025 allocating functions mark all registers as free. This eliminates some
1026 side effects resulting from peephole parser done earlier in the backbone
1028 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1030 * src/SDCCicode.c (geniCodeLogic),

1049 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1050 (aopForSym, aopOp): increment asmop.allocated if reused,
1051 (freeAsmop): decrement asmop.allocated and check for zero instead of
1053 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1054 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1055 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1078 2006-03-06 Borut Razem <borut.razem AT siol.net>
1080 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1081 made the linker quiet
1083 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1085 * src/pic16/gen.c (genPcall): fixed bug #1443644
1086 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1087 which dumps before the function entry point a data byte which represents
1088 the number of the local variables used by the specified function, added
1089 'xinst' for initial support for Extended Instruction Support,
1090 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1091 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1092 port->fun_prefix anymore (may change later),
1093 (genFunction, genEndFunction): do not store/restore local registers for
1094 _main (this should take care the --main-return command line option in
1096 (genOr): removed some legacy pic-port instructions,
1097 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1098 performing operations with SFR's causes data to be written more than
1099 once to each SFR. Perhaps SFRs should be handled in special cases...
1100 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1102 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1103 into account for stack starting position,
1104 (struct OPTIONS pic16_optionsTable): added command line argument
1105 --extended or -y for Extended Instruction Support,
1106 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1107 (deassignLRs): *** perhaps the most important change, old 'for' code
1108 (commented out for reference), didn't account for some registers which
1109 were left marked 'not free' after a pointer operation. The change
1110 reduces register usage a lot in some cases
1112 2006-03-04 Borut Razem <borut.razem AT siol.net>
1114 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3486 placed in access bank. This was necessery because some times they
3487 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3488 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3489 optimizations. Currently only compare to unsigned char is implemented,
3490 * src/pic16/gen.c: added fReturnIdx array,
3491 * (struct resolvedIfx) is moved to gen.h and made public,
3492 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3493 * (aopForSym): added an optimization to directly store in stack of
3494 the operand of a SEND iCode,
3495 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3496 but as registers instead (AOP_REG) using the fReturnIdx array,
3497 * (pic16_freeAsmop): remove the freed register from the
3498 _G.sregsAlloc field,
3499 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3500 a compare of 'WREG',
3501 * (pic16_popGetTempRegCond): changed function prototype, now
3502 function takes also a bitVector argument v which holds the current
3503 set of registers that are allocated for stack access by aopForSym,
3504 registers allocated in aopForSym for accessing stack symbols are not
3505 any more part of the functions usedRegs field,
3506 * (genCall): some times aopOp is called for a stack variable to be
3507 send, aopForSym might perform the push, if this is true make sure
3508 that genCall doesn't push the variable twice by testing _G.resDirect,
3509 * (genFunction): changed testing for unspecified interrupt number
3510 from 256 to INTNO_UNSPEC,
3511 * modified selection scheme of frame pointer generation. Previously
3512 if function did use local registers a frame pointer was generated,
3513 now a frame pointer is generated only if function has arguments
3514 (that need PLUSW2 register access), or has stack arguments, or the
3515 compiler is not instructed to omit the frame pointer,
3516 * (genEndFunction): before restoring local registers that were saved
3517 in the function preamble, also restore the registers that *might*
3518 have been allocated for stack access,
3519 * (genRet): removed some old comments,
3520 * (genCmp, the active (RN's) version): added a call to the
3521 pic16_genCmp_special function to perform the compare with a more
3522 robust and optimized way,
3523 * (genInline): a feature has been added in inline code generation,
3524 which allows a wildcard variable substitution when writing inline
3525 assembly. Code is incomplete and experimental therefore undocumented,
3526 * (genCast): changed order of aopOp for result and right to allow
3527 aopForSym to directly load the result if possible,
3528 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3529 perform an optimized compare on some selected special occasions,
3530 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3531 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3532 generate an IVT any more,
3533 * src/pic16/main.c (pic16_optionsTable): added command line option
3535 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3536 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3538 * src/pic16/NOTES: Raphael Neider added in list of active developers
3539 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3540 jumptable_end to prevent bug #,
3541 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3542 inCond and outCond fields,
3543 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3544 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3545 turn off register spilling,
3546 * (packRegsForOneUse): synced with other ports' versions although it
3547 is not used currently,
3548 * (pic16_packRegisters): added an optimization while reading
3549 structure bitfields, some registers may be saved (malloc code is
3550 decreased by 80 bytes)
3552 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3554 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3555 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3556 this can be optimized more?
3558 2005-03-10 Raphael Neider <rneider AT web.de>
3560 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3561 genNearPointerGet): (hopefully) fixed access to bitfields via

3888 access stack and frame pointers. They are initially assigned to
3889 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3890 accessing SFRs. Updated all occurences of modification of stack or
3891 frame pointer in gen.c and pcode.c,
3892 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3893 assigning of a literal value to pointers,

4197 generated for switch statements. For now you need to set the
4198 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4199 Now 4 algorithms for mcs51 jumptable generation are used:
4200 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4234 * added libc directory. The current version of LibC contains string
4235 functions, ctype functions and macros and some functions of the
4236 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4237 be extensively tested in the future. Standard disclaimer here.

4251 * (genCmp): experimental code for new genCmp which uses PIC18's
4252 special compare&skip instructions. Initial tests fail some times
4253 with variables grater than 1 byte in size, so new code is disabled,
4254 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4256 * (genCast): began a fix to optimize the casting of a bit to another
4257 bit, now assigning a bitfield to another bitfield will fail, sorry,

4271 registers when it shouldn't,
4272 * src/pic16/ralloc.c (allocReg): add preliminary support for
4273 supporting a limited set of temporary registers,
4275 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7280 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7282 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7283 loaded with the linker search paths (-L arguments) and the libraries
7284 to be linked with the current source (-l arguments). Changes
7285 currently will affect only the pic16 port.
7286 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7287 include path the port specific paths and port specific libraries,
7288 * gplink command now contains the $3 argument,
7289 * src/pic16/device.h,
7290 * src/pic16/device.c,: structure PIC_device is made public and
7291 renamed to PIC16_device, the same for variable Pics which is renamed

7306 Documenting changes from previous commits.
7307 * configure.in (version 1.56),
7308 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7309 when generating output files to configure the pic16 library,
7310 but now I've commented it out, since gputils aren't installed in the
7311 SF compile farm, so library won't compile
7313 * device/lib/Makefile.in (version 1.56): initially I've added in
7314 target 'all' the prerequestive 'model-pic16' so it compiled the
7315 pic16 library, but now I've commented it out for the same reasons
7317 * added targets 'model-pic16' and 'objects-pic16' to compile the
7319 * added target 'port-specific-objects-pic16' to handle the
7320 generated libraries and copy them into the build/ directory
7321 * added target 'clean-intermediate-pic16' to clean intermediate
7322 files into pic16 directory
7323 * in target 'installdirs' added line to create directory pic16 in

7344 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7345 option so that it actually works. Made it specific to the z80, since
7346 the gbz80 doesn't have these kinds of I/O ports.
7348 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7350 * device/include/z180.h,

7374 via literal number. The symbol is placed in the corresponding
7375 position of the data ram
7376 * (pic16_dump_section): relocatable and absolute uninitialized
7377 data are now emitted in sorted order to reduce section naming,
7378 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7379 weren't marked as being in the access bank,
7381 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7383 Added portion of GNU PIC Library under the directory
7384 device/include/pic16 and device/lib/pic16. These files
7385 contain the declarations of SFRs for the PIC18Fxx2 devices.
7386 The directory is initialized via configure from toplevel.
7388 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7390 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7416 all over. Telling LaTeX to be less strict with word spacing
7417 to better keep the right margin. Changed some notes about
7418 maintainance of the ports in section 3.2.1 - is it OK like this?
7420 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
7422 SDCC source changes:
7423 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,
7424 convilong): modified to inform the pic16 port that builtin functions
7427 PIC16 PORT specific changes:
7428 * src/pic16/device.c pic16_dump_equates() added,
7429 processor registers declared internally by the port are emitted in
7430 the translation as equates,
7431 * src/pic16/gen.c: inline code is passed unprocessed to the
7433 * (pic16_popGetLit2): fnuction modified to take second operand as
7434 pCodeOp pointer and not as literal,
7435 * (popRegFromIdx): prefixed with pic16_,

7438 * (pic16_pushpCodeOpReg, pic16_poppCodeOpReg): added
7439 * (genFunction): initializes local stack frame and pushes on stack
7440 all the registers used by this function,
7441 * (genEndFunction): restores all registers from stack and restores
7443 * src/pic16/glue.c (pic16emitRegularMap): various changes and

7457 UPPER for immediate operands,
7458 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7460 * src/pic16/peeph.def: all peepholes with movff are commented out,
7461 because there is a problem in the pcode peep optimizer,

7572 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7574 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7575 (default behaviour).
7577 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7579 A python script to validate compiler diagnostic messages. It can be
7580 used to verify that sdcc complains about bad c source code and
7581 gives a good location of the error.
7582 * support/valdiag/Makefile,
7583 * support/valdiag/valdiag.py,
7584 * support/valdiag/tests/*

7601 Bug reported from Jesus Calvino-Fraga
7603 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7605 * sdcc.spec: updated
7606 * device/include/Makefile.in: don't install CVS directories
7607 * device/lib/Makefile.in: added removal of CVS directories after install
7608 * doc/Makefile: fixed install, added local_icons
7609 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7610 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7611 * src/ds390/gen.c (genRightShift): fixed bug #870788
7612 * src/SDCCast.c (decorateType): fixed bug #870781
7614 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7616 PIC16 port related changes:
7617 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7618 added variable stackPos,
7620 * gen.c: genCall, assignResultValue: added support for
7621 pushing/retrieving function parameters to/from stack,
7622 genFunction,genEndFunction: setup stack frame for the
7624 genAddrOf: will be changed according to bug 863624
7626 * added files genutils.c and genutils.h which contain gen*
7627 debugged and optimised functions extracted from gen.c
7629 * glue.c: added variable 'externs' which holds extern symbols,
7630 pic16emitRegularMap: is modified to properly handle relocatable
7631 symbols under the new scheme,
7632 pic16createInterruptVect: is modified
7633 pic16printPublics: is modified to emit 'global' assembler directives,
7634 added pic16_printExterns to print extern symbols,
7635 pic16glue: initializes stack/frame pointer in the beginning of
7636 the assembly output. Temporary hack, will be corrected later,
7637 because gplink yet does not support stack and SDCC does not
7638 yet support a type of crt0.o object to create the final binary.
7640 * Removed many lines that contain 8051 legacy code.
7641 * The code is finally placed under a 'code' directive.
7642 * Added port specific options.
7644 * _process_pragma: simplified since now we do not need *special*
7645 include file to define SFR registers. But a separate header
7646 will be needed. This will be developed later.
7647 * _pic16_parseOptions: added, parses port specific options:
7648 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7649 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7650 --preplace-udata-with=
7652 * _pic16_setDefaultOptions: modified to initialize section names,
7653 but hack is temporarly out of order since it needs improvement.
7654 * _pic16_genAssemblerPreamble: configuration words are emitted by
7655 their address instead of their name. This part is incomplete and
7656 supports only the 18Fxx2 devices. Other devices will emit an error
7657 during assembly since they do not contain the same set of config
7659 * _pic16_genIVT: is modified,
7661 * pcode.c: added definitions for some hardware registers that are needed
7663 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7664 All PCI entries are updated. Now LFSR is supported.
7665 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7666 * added pic16_newpCodeOpLit2 to support instructions with
7667 two literal arguments
7668 * pic16_pCode2str: corrected code that emits assembler instructions
7669 with two literal operands and those that have an access bit modifier
7670 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7671 this fixes a bug which caused some labels to be lost, when an
7672 assembler directive was added, i.e. banksel,
7673 * pic16_FixRegisterBanking: improved logic that causes the insertion
7675 * InlineFunction: functions that are called once, are not any more
7676 inlined. This can be a port option in the future,
7678 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7680 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7681 hold the corresponding uninitialized symbols,
7682 * pic16_allocProcessorRegister: registers have explicit marked the
7684 * pic16_allocInternalRegister: registers are explicit marked as
7686 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7687 processing list, so bit registers were lost,
7690 * ralloc.h: added field 'accessBank' and original symbol operand
7691 in register definition,
7692 * removed the field isMapped from register definition,
7694 ** Several functions have been removed from various sources:
7695 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7696 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7697 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7698 pic16_assignRelocatableRegisters
7700 ** others have been introduced:
7701 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7702 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7704 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7706 * support/scripts/inc2h.pl: changed definition of BIT_AT
7707 to emit 'sbit at' instead of 'bit at'. This was a request.
7709 PIC16 port related preliminary changes:
7710 * gen.c: prefixed function popRegFromString with
7711 pic16_ and all references to it corrected
7712 * pcode.c: all pic16_pc_* hardware registers prefixed
7713 with underscore (_),
7714 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7715 * ralloc.c: newReg(): when register is REG_SFR then
7716 set address to rIdx,
7717 pic16_allocProcessorRegister(): marks register wasUsed=0
7718 pic16_writeUsedRegs(): added a call to assign processor
7719 registers via pic16_assignFixedRegisters
7721 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7723 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7724 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7725 variables in unused register banks. Also the SSEG is placed
7726 wherever there is enough space for it, and IDATA can be anywhere
7727 in internal RAM. For now compile using -Wl-Y[stack_size].
7728 The mem file is different for this option as well, since it
7729 makes no sense of talking about DSEG lenght.
7731 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7733 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7734 in certain cases, e.g. when ROM assignment, patch provided
7735 from Albert den Haan.
7737 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8739 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8740 fetching of the pointer
8741 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8742 copied from genNearPointerSet()
8743 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8744 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8760 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8761 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8762 type for bits was changed. It resulted in bit variables becoming
8763 global, which is not permitted in PIC 14 assembly output.
8765 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8767 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8780 A few small changes that speed up the peephole optimizer.
8784 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8786 Try to make the peephole optimizer smarter by maintaining
8787 an association between the assembly source code and the
8788 iCodes that originated them. Put this information to use
8789 with a new peephole rule condition "notVolatile" so that
8790 the rules can be aggressive yet still safe.
8795 * src/mcs51/peeph.def
8797 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8801 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8802 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8803 if the left or right operand symbols have the accuse flag set.
8805 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8807 Changed the type of the result of the ! (NOT) operator to char;
8808 previously it returned the same type as the source. This allows
8809 us to eliminate all the genFloatNot functions (all of its target
8810 implementations were very buggy) since !float can use the same
8813 * src/SDCCicode.c (ast2iCode): ! returns char

8822 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8823 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8824 during interrupts. Ensure WSAVE is located at a shared bank address.
8825 2. Fixed page selection in some places
8826 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8827 the registers name strings.
8828 4. Fixed "signed / unsigned compare" compiler warnings.
8829 5. The PIC port manages its own allocation of the general purpose
8830 registers, but makes no attempt to reuse them. As a result when
8831 compiling it soon runs out of general purpose registers. Some
8832 additional code was added to the files pcode.c and device.c to walk
8833 through the function call tree and rename the registers so that they
8843 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8844 genPlus() & genMinus() when the result is the same as left or right

8850 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8852 Made bitfield a distinct type from bit so that bitfields
8853 convert as per ANSI C and bits retain their traditional
8854 boolean style behaviour. Implemented bitfield support in
8862 * src/ds390/gen.c: bit v bitfield split
8863 * src/z80/gen.c: New support for bitfields
8864 * support/regression/tests/bitfields.c: reenabled z80,
8867 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8869 Rules 246.x, 247.x relate to bitfields, the others speed up
8870 access to xdata mapped I/O devices.
8872 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8874 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8876 Cleaned up genPackBits and genUnpackBits and added two helper
8877 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8878 for literal assignments in genPackBits (thanks to Frieder for
8884 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8886 Fixed bug #748310 (pointer to function type mishandled when the
8887 function name is omitted). Also fixed a SIGSEGV when a function
8888 attribute (reentrant, etc) is used on a non-function or on a
8889 function but misplaced before the parameter list.
8891 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8893 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8894 * support/Util/SDCCerr.h,

8916 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8918 Made the constant following the "interrupt" keyword optional. If
8919 omitted, the function will not automatically be given an entry
8920 in the interrupt vector table (similar to #pragma NOIV, but
8921 less syntacticly kludgy). The interrupt number is also now
8922 range checked. Also fixed a bug in the high order bit example

8938 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8940 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8941 be re-activated by defining REDUCE_LITERALS)
8942 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8943 unsigned, but are signed by default
8944 * src/SDCCval.c (constVal): rearranged
8945 * src/SDCCval.c (valMod): preliminary fix
8946 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9452 added if/endif conditional macros to remove options help
9453 messages from optionsTable when a port is not configured, added
9454 support for the PIc16 port in the ports table, when executing
9455 the compiler with no port specified on command line, a default
9456 port is selected with the new macro DEFAULT_PORT which is
9457 defined in port.h, in setDefaultOptions() linkOptions is removed
9458 from initialization assignment, since now it is a set,
9459 parseCmdLine uses setParseWithComma for linkOptions, in
9460 linkEdit() linkOptions are accessed with new function indexSet()
9461 which returns the i'th item of a set variable. See SDCCset.c, in
9462 linkEdit() when calling buildCmdLine(), added linkOptions as
9463 last argument. Now users can pass arguments to gplink via the
9464 -Wl option, main() uses pic16glue() to glue up pic16 programs

9478 gpasm complaining and test the linkage with gplink, _linkCmd and
9479 _asmCmd changed to be more gplink and gpasm friendly
9480 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9481 produced an error when parsed, peep rule 12 is added to utilize
9482 movff, but it is commented out since the pCode does not support
9483 yet a command with 2 address arguments
9485 2003-05-18 <johan AT balder>
9487 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9510 2003-05-12 Borut Razem <borut.razem AT siol.net>
9512 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9514 2003-05-11 Borut Razem <borut.razem AT siol.net>
9516 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9517 the path of bin directory, so that PATH is the only env. variable, which has to be set

10546 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10548 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10550 * in \sdcc\as\mcs51\ changed these files in order to create an
10551 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10552 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10553 following files to include the previous two files: aslink.dsp,
10554 Makefile.aslink, Makefile.bcc, and Makefile.in.
10556 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10557 .adb instead of .cdb
10559 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10561 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10562 value from option --iram-size.
10564 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10566 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10569 2002-09-18 <wiml AT hhhh.org>
10571 * SDCClrange.h: exposed setFromRange() and setToRange()
10572 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10573 packRegsForAccUse() (bug 542397)
10574 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10575 multiple times and emitting the fetch operations more than once
10576 added aopGetUsesAcc() function to allow binary operators to
10577 fetch their operands in the correct order; made genMinus() emit
10578 compact code for X = LITERAL - Y
10580 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10581 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10582 sprintf() in line 1267.
10584 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10585 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10588 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10589 Changes to aslink (All the changes are marked with 'JCF'):
10591 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10594 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10595 area BSEG. Also moves, if possible, the DATA area down into the internal
10596 ram so more space is available.
10598 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10601 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10602 not bytes. Function summary() which creates a memory usage summary
10603 file with extension .mem. Reports of overlaping stack and small stack
10604 size. If the space for the stack is less than 16 bytes aslink trows a
10607 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10608 the 8051. Option 'y' for memory summary output file.
10610 Changes to sdcc (All the changes are marked with 'JCF'):
10612 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10614 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10615 overlaying area for it (uses RegBankUsed[4]).
10617 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10618 bank zero as used by default. By default aslink locates the stack
10619 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10620 the creation of the .mem file. Delegates the allocation of data area
10621 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10622 the begining of the stack area to aslink.
10624 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10625 glue() in SDCCglue.c creates an area for it.
10627 2002-09-03 Borut Razem <borut.razem AT siol.net>
10628 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10629 sdcc/src/pic/glue.c:
10630 introduced atexit() handler for teporay files removal in case of
10631 errors, assertions, ...
10633 2002-08-29 Borut Razem <borut.razem AT siol.net>
10634 * sdcc/support/cpp2/auto-host_vc_in.h:
10635 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10636 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10637 Maybe there is a similar problem with BORLANDC? It should be checked!
10639 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10640 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10641 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10642 was not executed, and the compiler (cl) launched a warning:
10643 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10645 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10646 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10648 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10649 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

10652 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10653 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10654 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10655 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10656 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10657 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10658 - added Release configuration in VS projects
10659 - review of compiler an linker options
10660 - VC .exe files are generated in bin_vc directory, not to interfere
10661 with binaries generated from other projects (cygwin, mingw, bcc ...)
10663 * sdcc/src/yacc.dsp: added
10665 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10666 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10667 and insert the version number definitions from .version
10669 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10671 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10672 added - genarate auto-host.h using auto-host_vc_in.h as template
10675 removed from CVS, generated automatically
10677 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10678 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10680 2002-08-11 Borut Razem <borut.razem AT siol.net>
10681 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10683 2002-08-10 Borut Razem <borut.razem AT siol.net>
10684 * src/SDCCmain.c (main):
10685 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10686 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10687 The consequence was that some temporary files were not removed.
10690 unification of code in functions tempfilename() and tempfile():
10691 function tempnam() is defined in Visual Studio 6.0 and .NET
10693 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10695 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10696 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10697 - removed compiler command line option /WX: Treats all warnings as errors
10698 - update a list of source files, included into the project
10700 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10701 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10702 changed project type to Generic Project so that can be correcly converted to VS.NET project
10704 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10706 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10708 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10710 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10711 added return 0 statements after assert() to make compiler happy
10713 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10714 added newline in the def file to keep MSC compiler satisfied
10716 * sdcc/src/z80/gen.c:
10717 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10718 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10719 - solved MSC error in function aopDump()
10721 * sdcc_vc.h: define PREFIX as "\\sdcc"
10723 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10765 * src/SDCCval.c: fixed bug #532436
10767 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10769 Added "char *Processor" field to the port structure.
10772 Added -p option. Allows port dependent processor to be specified.
10775 Initialized the new field char *Processor field to NULL in all ports
10778 Compiler generated registers for interrupt context saving
10779 were not getting allocated.
10781 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10784 Fixed left shift. Will promote the left side of a left shift
10785 if a) left shifting more than size of operand or b) when assigned
10786 to something size > size of left side
10788 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10791 rewritten. Added customization for the various PICs. Flow
10792 analysis is restructured. ...
10794 * src/pic/device.h:
10797 * src/pic/device.c:
10798 Added. device.c is a PIC port hack to accomodate variations
10801 2002-03-13 Michael Hope <michaelh AT vroom>
10803 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10805 2002-03-04 johanknol <johanknol AT manik>
10807 * /src/SDCCval.c: fixed
10809 const unsigned char arr[][2] = { { 0, 1 } };
