667 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
669 Enabled VPATH feature: changed nearly all Makefiles (149 files).
670 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
672 One basic decision: e.g. src/clean.mk includes further files. In order
673 to make this work there are two solutions:
674 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
675 run configure on them. This way they can use
676 'include $(srcdir)/port-clean.mk'
677 - always include clean.mk by the Makefile at the same level. To avoid
678 that `make clean` tries to include and build Makefile.dep the
679 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
680 implemented, because now even `make uninstall` doesn't create
681 Makefile.in. clean.mk could be eliminated by pasting it in
684 * debugger/mcs51/Makefile.in: build own objects from library sources
685 (SLIB, SDCC) in current directory
687 * configure, configure.in: renamed --disable-device-lib-build in
688 --disable-device-lib; added --enable-doc, the required tools are
689 searched by configure; added result message; the toolchain for the
690 belonging ports are now only built, if the port is enabled.
692 * support/regression/*: all output is written in directory gen, because
693 the fwk and ports directories don't livet in the build tree using vpath
695 * doc/sdccman.lyx: renamed --disable-device-lib-build to
696 --disable-device-lib, added --enable-doc, added section VPATH
698 * sim/ucsim/configure.in,
699 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
700 z80 are enabled by default
702 2006-04-24 Raphael Neider <rneider AT web.de>
704 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
705 to config word, "pic14_"-prefixed some extern functions
706 (pic14_emitConfigWord): emit __config directive(s) if assignment to
707 config word has been found
708 * src/pic/device.h: added prototypes
709 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

959 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
961 * src/SDCCpeeph.c (operandsLiteral): new, added,

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

983 submitted by the Debian SDCC maintainer Aurelien Jarno:
984 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
985 archive with gcc 4.1 on mips and wrote the patch"
987 2006-03-16 Raphael Neider <rneider AT web.de>
989 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
990 the left operand is shorter than the result (c* = lit-c* + int),
992 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
995 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
997 * src/.version: increased version number to 2.5.5
998 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
999 linking is done manually in pic16 port's _linkEdit,
1000 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1001 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1002 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1003 allocate asmop as AOP_ACC,
1004 (aopForRemat): added parameter 'bool result' in function declaration,
1005 (pic16_aopGet): return AOP_ACC when accessing WREG,
1006 (pic16_popGetTempReg): minor modification,
1007 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1008 'pic16_allocWithIdx',
1009 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1010 calling function in absolute addresses,
1011 (genAssign): take into account AOP_ACC asmop,
1012 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1015 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1017 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1018 call to allocReg, not by manually allocating a new one,
1019 (pic16_assignRegisters): now before going through the register
1020 allocating functions mark all registers as free. This eliminates some
1021 side effects resulting from peephole parser done earlier in the backbone
1023 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1081 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1082 which dumps before the function entry point a data byte which represents
1083 the number of the local variables used by the specified function, added
1084 'xinst' for initial support for Extended Instruction Support,
1085 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1086 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1087 port->fun_prefix anymore (may change later),
1088 (genFunction, genEndFunction): do not store/restore local registers for
1089 _main (this should take care the --main-return command line option in
1091 (genOr): removed some legacy pic-port instructions,
1092 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1093 performing operations with SFR's causes data to be written more than
1094 once to each SFR. Perhaps SFRs should be handled in special cases...
1095 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1097 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1100 --extended or -y for Extended Instruction Support,
1101 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1102 (deassignLRs): *** perhaps the most important change, old 'for' code
1103 (commented out for reference), didn't account for some registers which
1104 were left marked 'not free' after a pointer operation. The change
1105 reduces register usage a lot in some cases

3486 * (struct resolvedIfx) is moved to gen.h and made public,
3487 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3488 * (aopForSym): added an optimization to directly store in stack of
3489 the operand of a SEND iCode,
3490 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3491 but as registers instead (AOP_REG) using the fReturnIdx array,
3492 * (pic16_freeAsmop): remove the freed register from the
3493 _G.sregsAlloc field,
3494 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3495 a compare of 'WREG',
3496 * (pic16_popGetTempRegCond): changed function prototype, now
3497 function takes also a bitVector argument v which holds the current
3498 set of registers that are allocated for stack access by aopForSym,
3499 registers allocated in aopForSym for accessing stack symbols are not
3500 any more part of the functions usedRegs field,
3501 * (genCall): some times aopOp is called for a stack variable to be
3502 send, aopForSym might perform the push, if this is true make sure
3503 that genCall doesn't push the variable twice by testing _G.resDirect,
3504 * (genFunction): changed testing for unspecified interrupt number
3505 from 256 to INTNO_UNSPEC,
3506 * modified selection scheme of frame pointer generation. Previously
3507 if function did use local registers a frame pointer was generated,
3508 now a frame pointer is generated only if function has arguments
3509 (that need PLUSW2 register access), or has stack arguments, or the
3510 compiler is not instructed to omit the frame pointer,
3511 * (genEndFunction): before restoring local registers that were saved
3512 in the function preamble, also restore the registers that *might*
3513 have been allocated for stack access,
3514 * (genRet): removed some old comments,
3515 * (genCmp, the active (RN's) version): added a call to the
3516 pic16_genCmp_special function to perform the compare with a more
3517 robust and optimized way,
3518 * (genInline): a feature has been added in inline code generation,
3519 which allows a wildcard variable substitution when writing inline
3520 assembly. Code is incomplete and experimental therefore undocumented,
3521 * (genCast): changed order of aopOp for result and right to allow
3522 aopForSym to directly load the result if possible,
3523 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3524 perform an optimized compare on some selected special occasions,
3525 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3526 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3527 generate an IVT any more,
3528 * src/pic16/main.c (pic16_optionsTable): added command line option
3530 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3531 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3533 * src/pic16/NOTES: Raphael Neider added in list of active developers
3534 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3535 jumptable_end to prevent bug #,
3536 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3537 inCond and outCond fields,
3538 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3539 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3540 turn off register spilling,
3541 * (packRegsForOneUse): synced with other ports' versions although it
3542 is not used currently,
3543 * (pic16_packRegisters): added an optimization while reading
3544 structure bitfields, some registers may be saved (malloc code is
3545 decreased by 80 bytes)
3547 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3549 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3550 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3551 this can be optimized more?
3553 2005-03-10 Raphael Neider <rneider AT web.de>
3555 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3556 genNearPointerGet): (hopefully) fixed access to bitfields via
3557 pointers (p->bitN = x; and x = p->bitN; failed)

3883 access stack and frame pointers. They are initially assigned to
3884 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3885 accessing SFRs. Updated all occurences of modification of stack or
3886 frame pointer in gen.c and pcode.c,

4192 generated for switch statements. For now you need to set the
4193 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4194 Now 4 algorithms for mcs51 jumptable generation are used:
4195 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4196 addresses loaded pc-relative for up to 112 cases and stack-pushing
4197 target addresses loaded with offset from dptr for up to 256 cases.

4229 * added libc directory. The current version of LibC contains string
4230 functions, ctype functions and macros and some functions of the
4231 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4232 be extensively tested in the future. Standard disclaimer here.

4246 * (genCmp): experimental code for new genCmp which uses PIC18's
4247 special compare&skip instructions. Initial tests fail some times
4248 with variables grater than 1 byte in size, so new code is disabled,
4249 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4251 * (genCast): began a fix to optimize the casting of a bit to another
4252 bit, now assigning a bitfield to another bitfield will fail, sorry,

4266 registers when it shouldn't,
4267 * src/pic16/ralloc.c (allocReg): add preliminary support for
4268 supporting a limited set of temporary registers,
4270 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7278 loaded with the linker search paths (-L arguments) and the libraries
7279 to be linked with the current source (-l arguments). Changes
7280 currently will affect only the pic16 port.
7281 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7282 include path the port specific paths and port specific libraries,
7283 * gplink command now contains the $3 argument,
7284 * src/pic16/device.h,
7285 * src/pic16/device.c,: structure PIC_device is made public and
7286 renamed to PIC16_device, the same for variable Pics which is renamed

7301 Documenting changes from previous commits.
7302 * configure.in (version 1.56),
7303 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7304 when generating output files to configure the pic16 library,
7305 but now I've commented it out, since gputils aren't installed in the
7306 SF compile farm, so library won't compile
7308 * device/lib/Makefile.in (version 1.56): initially I've added in
7309 target 'all' the prerequestive 'model-pic16' so it compiled the
7310 pic16 library, but now I've commented it out for the same reasons
7312 * added targets 'model-pic16' and 'objects-pic16' to compile the
7314 * added target 'port-specific-objects-pic16' to handle the
7315 generated libraries and copy them into the build/ directory
7316 * added target 'clean-intermediate-pic16' to clean intermediate
7317 files into pic16 directory
7318 * in target 'installdirs' added line to create directory pic16 in

7340 option so that it actually works. Made it specific to the z80, since
7341 the gbz80 doesn't have these kinds of I/O ports.
7343 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7345 * device/include/z180.h,

7567 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7569 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7570 (default behaviour).
7572 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7574 A python script to validate compiler diagnostic messages. It can be
7575 used to verify that sdcc complains about bad c source code and
7576 gives a good location of the error.
7577 * support/valdiag/Makefile,
7578 * support/valdiag/valdiag.py,
7579 * support/valdiag/tests/*

7596 Bug reported from Jesus Calvino-Fraga
7598 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7600 * sdcc.spec: updated
7601 * device/include/Makefile.in: don't install CVS directories
7602 * device/lib/Makefile.in: added removal of CVS directories after install
7603 * doc/Makefile: fixed install, added local_icons
7604 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7605 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7606 * src/ds390/gen.c (genRightShift): fixed bug #870788
7607 * src/SDCCast.c (decorateType): fixed bug #870781
7609 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7611 PIC16 port related changes:
7612 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7613 added variable stackPos,
7615 * gen.c: genCall, assignResultValue: added support for
7616 pushing/retrieving function parameters to/from stack,
7617 genFunction,genEndFunction: setup stack frame for the
7619 genAddrOf: will be changed according to bug 863624
7621 * added files genutils.c and genutils.h which contain gen*
7622 debugged and optimised functions extracted from gen.c
7624 * glue.c: added variable 'externs' which holds extern symbols,
7625 pic16emitRegularMap: is modified to properly handle relocatable
7626 symbols under the new scheme,
7627 pic16createInterruptVect: is modified
7628 pic16printPublics: is modified to emit 'global' assembler directives,
7629 added pic16_printExterns to print extern symbols,
7630 pic16glue: initializes stack/frame pointer in the beginning of
7631 the assembly output. Temporary hack, will be corrected later,
7632 because gplink yet does not support stack and SDCC does not
7633 yet support a type of crt0.o object to create the final binary.
7635 * Removed many lines that contain 8051 legacy code.
7636 * The code is finally placed under a 'code' directive.
7637 * Added port specific options.
7639 * _process_pragma: simplified since now we do not need *special*
7640 include file to define SFR registers. But a separate header
7641 will be needed. This will be developed later.
7642 * _pic16_parseOptions: added, parses port specific options:
7643 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7644 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7645 --preplace-udata-with=
7647 * _pic16_setDefaultOptions: modified to initialize section names,
7648 but hack is temporarly out of order since it needs improvement.
7649 * _pic16_genAssemblerPreamble: configuration words are emitted by
7650 their address instead of their name. This part is incomplete and
7651 supports only the 18Fxx2 devices. Other devices will emit an error
7652 during assembly since they do not contain the same set of config
7654 * _pic16_genIVT: is modified,
7656 * pcode.c: added definitions for some hardware registers that are needed
7658 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7659 All PCI entries are updated. Now LFSR is supported.
7660 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7661 * added pic16_newpCodeOpLit2 to support instructions with
7662 two literal arguments
7663 * pic16_pCode2str: corrected code that emits assembler instructions
7664 with two literal operands and those that have an access bit modifier
7665 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7666 this fixes a bug which caused some labels to be lost, when an
7667 assembler directive was added, i.e. banksel,
7668 * pic16_FixRegisterBanking: improved logic that causes the insertion
7670 * InlineFunction: functions that are called once, are not any more
7671 inlined. This can be a port option in the future,
7673 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7675 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7676 hold the corresponding uninitialized symbols,
7677 * pic16_allocProcessorRegister: registers have explicit marked the
7679 * pic16_allocInternalRegister: registers are explicit marked as
7681 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7682 processing list, so bit registers were lost,
7685 * ralloc.h: added field 'accessBank' and original symbol operand
7686 in register definition,
7687 * removed the field isMapped from register definition,
7689 ** Several functions have been removed from various sources:
7690 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7691 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7692 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7693 pic16_assignRelocatableRegisters
7695 ** others have been introduced:
7696 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7697 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7699 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7701 * support/scripts/inc2h.pl: changed definition of BIT_AT
7702 to emit 'sbit at' instead of 'bit at'. This was a request.
7704 PIC16 port related preliminary changes:
7705 * gen.c: prefixed function popRegFromString with
7706 pic16_ and all references to it corrected
7707 * pcode.c: all pic16_pc_* hardware registers prefixed
7708 with underscore (_),
7709 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7710 * ralloc.c: newReg(): when register is REG_SFR then
7711 set address to rIdx,
7712 pic16_allocProcessorRegister(): marks register wasUsed=0
7713 pic16_writeUsedRegs(): added a call to assign processor
7714 registers via pic16_assignFixedRegisters
7716 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7718 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7719 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7720 variables in unused register banks. Also the SSEG is placed
7721 wherever there is enough space for it, and IDATA can be anywhere
7722 in internal RAM. For now compile using -Wl-Y[stack_size].
7723 The mem file is different for this option as well, since it
7724 makes no sense of talking about DSEG lenght.
7726 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7728 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7729 in certain cases, e.g. when ROM assignment, patch provided
7730 from Albert den Haan.
7732 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8734 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8735 fetching of the pointer
8736 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8737 copied from genNearPointerSet()
8738 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8739 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8740 If they pop r0/r1 they must be called in the opposite order than aopOp().
8741 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8742 (resp. --stack-auto), prepared for --xstack

8753 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8755 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8756 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8757 type for bits was changed. It resulted in bit variables becoming
8758 global, which is not permitted in PIC 14 assembly output.
8760 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8762 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8775 A few small changes that speed up the peephole optimizer.
8779 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8781 Try to make the peephole optimizer smarter by maintaining
8782 an association between the assembly source code and the
8783 iCodes that originated them. Put this information to use
8784 with a new peephole rule condition "notVolatile" so that
8785 the rules can be aggressive yet still safe.
8790 * src/mcs51/peeph.def
8792 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8796 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8797 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8798 if the left or right operand symbols have the accuse flag set.
8800 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8802 Changed the type of the result of the ! (NOT) operator to char;
8803 previously it returned the same type as the source. This allows
8804 us to eliminate all the genFloatNot functions (all of its target
8805 implementations were very buggy) since !float can use the same
8808 * src/SDCCicode.c (ast2iCode): ! returns char
8809 * src/mcs51/gen.c (genNot, genNotFloat),
8810 * src/ds390/gen.c (genNot, genNotFloat),
8811 * src/z80/gen.c (genNot, genNotFloat),
8812 * src/pic/gen.c (genNot, genNotFloat),

8815 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8817 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8818 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8819 during interrupts. Ensure WSAVE is located at a shared bank address.
8820 2. Fixed page selection in some places
8821 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8822 the registers name strings.
8823 4. Fixed "signed / unsigned compare" compiler warnings.
8824 5. The PIC port manages its own allocation of the general purpose
8825 registers, but makes no attempt to reuse them. As a result when
8826 compiling it soon runs out of general purpose registers. Some
8827 additional code was added to the files pcode.c and device.c to walk
8828 through the function call tree and rename the registers so that they
8838 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8839 genPlus() & genMinus() when the result is the same as left or right
8841 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8845 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8847 Made bitfield a distinct type from bit so that bitfields
8848 convert as per ANSI C and bits retain their traditional
8849 boolean style behaviour. Implemented bitfield support in
8857 * src/ds390/gen.c: bit v bitfield split
8858 * src/z80/gen.c: New support for bitfields
8859 * support/regression/tests/bitfields.c: reenabled z80,
8862 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8864 Rules 246.x, 247.x relate to bitfields, the others speed up
8865 access to xdata mapped I/O devices.
8867 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8869 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8871 Cleaned up genPackBits and genUnpackBits and added two helper
8872 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8873 for literal assignments in genPackBits (thanks to Frieder for
8879 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8881 Fixed bug #748310 (pointer to function type mishandled when the
8882 function name is omitted). Also fixed a SIGSEGV when a function
8883 attribute (reentrant, etc) is used on a non-function or on a
8884 function but misplaced before the parameter list.
8886 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8888 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8889 * support/Util/SDCCerr.h,
8890 * support/Util/SDCCerr.c: Added func attr misuse error msg
8892 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8894 Fixed bug #787649 by anonymous
8895 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8911 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8913 Made the constant following the "interrupt" keyword optional. If
8914 omitted, the function will not automatically be given an entry
8915 in the interrupt vector table (similar to #pragma NOIV, but
8916 less syntacticly kludgy). The interrupt number is also now
8917 range checked. Also fixed a bug in the high order bit example

8931 * src/SDCCicode.c (operandOperation): rewritten some ops
8932 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8933 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8935 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8936 be re-activated by defining REDUCE_LITERALS)
8937 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8938 unsigned, but are signed by default
8939 * src/SDCCval.c (constVal): rearranged
8940 * src/SDCCval.c (valMod): preliminary fix
8941 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8983 constants are unsigned; added recognition of "u" flag for unsigned
8984 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8985 * src/SDCCval.c (valDiv, valMod): fixed signdness

9447 added if/endif conditional macros to remove options help
9448 messages from optionsTable when a port is not configured, added
9449 support for the PIc16 port in the ports table, when executing
9450 the compiler with no port specified on command line, a default
9451 port is selected with the new macro DEFAULT_PORT which is
9452 defined in port.h, in setDefaultOptions() linkOptions is removed
9453 from initialization assignment, since now it is a set,
9454 parseCmdLine uses setParseWithComma for linkOptions, in
9455 linkEdit() linkOptions are accessed with new function indexSet()
9456 which returns the i'th item of a set variable. See SDCCset.c, in
9457 linkEdit() when calling buildCmdLine(), added linkOptions as
9458 last argument. Now users can pass arguments to gplink via the
9459 -Wl option, main() uses pic16glue() to glue up pic16 programs

9473 gpasm complaining and test the linkage with gplink, _linkCmd and
9474 _asmCmd changed to be more gplink and gpasm friendly
9475 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9476 produced an error when parsed, peep rule 12 is added to utilize
9477 movff, but it is commented out since the pCode does not support
9478 yet a command with 2 address arguments
9480 2003-05-18 <johan AT balder>
9482 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9509 2003-05-11 Borut Razem <borut.razem AT siol.net>
9511 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10540 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10541 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10543 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10545 * in \sdcc\as\mcs51\ changed these files in order to create an
10546 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10547 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10548 following files to include the previous two files: aslink.dsp,
10549 Makefile.aslink, Makefile.bcc, and Makefile.in.
10551 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10552 .adb instead of .cdb
10554 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10556 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10557 value from option --iram-size.
10559 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10561 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10564 2002-09-18 <wiml AT hhhh.org>
10566 * SDCClrange.h: exposed setFromRange() and setToRange()
10567 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10568 packRegsForAccUse() (bug 542397)
10569 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10570 multiple times and emitting the fetch operations more than once
10571 added aopGetUsesAcc() function to allow binary operators to
10572 fetch their operands in the correct order; made genMinus() emit
10573 compact code for X = LITERAL - Y
10575 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10576 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10577 sprintf() in line 1267.
10579 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10580 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10583 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10584 Changes to aslink (All the changes are marked with 'JCF'):
10586 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10589 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10590 area BSEG. Also moves, if possible, the DATA area down into the internal
10591 ram so more space is available.
10593 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10596 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10597 not bytes. Function summary() which creates a memory usage summary
10598 file with extension .mem. Reports of overlaping stack and small stack
10599 size. If the space for the stack is less than 16 bytes aslink trows a
10602 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10603 the 8051. Option 'y' for memory summary output file.
10605 Changes to sdcc (All the changes are marked with 'JCF'):
10607 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10609 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10610 overlaying area for it (uses RegBankUsed[4]).
10612 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10613 bank zero as used by default. By default aslink locates the stack
10614 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10615 the creation of the .mem file. Delegates the allocation of data area
10616 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10617 the begining of the stack area to aslink.
10619 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10620 glue() in SDCCglue.c creates an area for it.
10622 2002-09-03 Borut Razem <borut.razem AT siol.net>
10623 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10624 sdcc/src/pic/glue.c:
10625 introduced atexit() handler for teporay files removal in case of
10626 errors, assertions, ...
10628 2002-08-29 Borut Razem <borut.razem AT siol.net>
10629 * sdcc/support/cpp2/auto-host_vc_in.h:
10630 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10631 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10632 Maybe there is a similar problem with BORLANDC? It should be checked!
10634 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10635 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10636 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10637 was not executed, and the compiler (cl) launched a warning:
10638 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10640 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10641 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10643 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10644 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10646 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10647 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10648 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10649 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10650 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10651 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10652 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10653 - added Release configuration in VS projects
10654 - review of compiler an linker options
10655 - VC .exe files are generated in bin_vc directory, not to interfere
10656 with binaries generated from other projects (cygwin, mingw, bcc ...)
10658 * sdcc/src/yacc.dsp: added
10660 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10661 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10662 and insert the version number definitions from .version
10664 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10666 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10667 added - genarate auto-host.h using auto-host_vc_in.h as template
10670 removed from CVS, generated automatically
10672 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10673 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10675 2002-08-11 Borut Razem <borut.razem AT siol.net>
10676 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10678 2002-08-10 Borut Razem <borut.razem AT siol.net>
10679 * src/SDCCmain.c (main):
10680 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10681 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10682 The consequence was that some temporary files were not removed.
10685 unification of code in functions tempfilename() and tempfile():
10686 function tempnam() is defined in Visual Studio 6.0 and .NET
10688 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10690 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10691 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10692 - removed compiler command line option /WX: Treats all warnings as errors
10693 - update a list of source files, included into the project
10695 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10696 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10697 changed project type to Generic Project so that can be correcly converted to VS.NET project
10699 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10701 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10703 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10705 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10706 added return 0 statements after assert() to make compiler happy
10708 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10709 added newline in the def file to keep MSC compiler satisfied
10711 * sdcc/src/z80/gen.c:
10712 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10713 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10714 - solved MSC error in function aopDump()
10716 * sdcc_vc.h: define PREFIX as "\\sdcc"
10718 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10719 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10722 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10723 - Rewrote the register banking algorithm.
10724 - Added pCode live-range analysis to registers (for now, only non-used and
10725 singly-used registers optimized away)
10727 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10729 * 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.

10756 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10758 2002-03-28 Johan Knol <johan AT balder>
10760 * src/SDCCval.c: fixed bug #532436
10762 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10764 Added "char *Processor" field to the port structure.
10767 Added -p option. Allows port dependent processor to be specified.
10770 Initialized the new field char *Processor field to NULL in all ports
10773 Compiler generated registers for interrupt context saving
10774 were not getting allocated.
10776 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10779 Fixed left shift. Will promote the left side of a left shift
10780 if a) left shifting more than size of operand or b) when assigned
10781 to something size > size of left side
10783 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10785 tons of changes. Register allocation has been
10786 rewritten. Added customization for the various PICs. Flow
10787 analysis is restructured. ...
10789 * src/pic/device.h:
10792 * src/pic/device.c:
10793 Added. device.c is a PIC port hack to accomodate variations
10796 2002-03-13 Michael Hope <michaelh AT vroom>
10798 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10800 2002-03-04 johanknol <johanknol AT manik>
10802 * /src/SDCCval.c: fixed
10804 const unsigned char arr[][2] = { { 0, 1 } };
10805 t18.c:1: error: Initializer element is not constant
