662 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
664 Enabled VPATH feature: changed nearly all Makefiles (149 files).
665 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
667 One basic decision: e.g. src/clean.mk includes further files. In order
668 to make this work there are two solutions:
669 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
670 run configure on them. This way they can use
671 'include $(srcdir)/port-clean.mk'
672 - always include clean.mk by the Makefile at the same level. To avoid
673 that `make clean` tries to include and build Makefile.dep the
674 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
675 implemented, because now even `make uninstall` doesn't create
676 Makefile.in. clean.mk could be eliminated by pasting it in
679 * debugger/mcs51/Makefile.in: build own objects from library sources
680 (SLIB, SDCC) in current directory
682 * configure, configure.in: renamed --disable-device-lib-build in
683 --disable-device-lib; added --enable-doc, the required tools are
684 searched by configure; added result message; the toolchain for the
685 belonging ports are now only built, if the port is enabled.
687 * support/regression/*: all output is written in directory gen, because
688 the fwk and ports directories don't livet in the build tree using vpath
690 * doc/sdccman.lyx: renamed --disable-device-lib-build to
691 --disable-device-lib, added --enable-doc, added section VPATH
693 * sim/ucsim/configure.in,
694 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
695 z80 are enabled by default
697 2006-04-24 Raphael Neider <rneider AT web.de>
699 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
700 to config word, "pic14_"-prefixed some extern functions
701 (pic14_emitConfigWord): emit __config directive(s) if assignment to
702 config word has been found
703 * src/pic/device.h: added prototypes
704 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

954 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
956 * src/SDCCpeeph.c (operandsLiteral): new, added,
957 (callFuncByName): inserted operandsLiteral

967 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
968 implemented patch 1120823 Thanks to Willy De la Court (normal
969 interrupts need an interrupt number now if they are made critical),
970 and enabled nesting of critical functions though not for gbz80
971 (genCritical, genEndCritical): added functions
972 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
973 * src/z80/mappings.i: added "ei" to all mappings
975 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

978 submitted by the Debian SDCC maintainer Aurelien Jarno:
979 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
980 archive with gcc 4.1 on mips and wrote the patch"
982 2006-03-16 Raphael Neider <rneider AT web.de>
984 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
985 the left operand is shorter than the result (c* = lit-c* + int),
987 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
990 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
992 * src/.version: increased version number to 2.5.5
993 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
994 linking is done manually in pic16 port's _linkEdit,
995 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
996 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
997 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
998 allocate asmop as AOP_ACC,
999 (aopForRemat): added parameter 'bool result' in function declaration,
1000 (pic16_aopGet): return AOP_ACC when accessing WREG,
1001 (pic16_popGetTempReg): minor modification,
1002 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1003 'pic16_allocWithIdx',
1004 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1005 calling function in absolute addresses,
1006 (genAssign): take into account AOP_ACC asmop,
1007 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1010 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1012 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1013 call to allocReg, not by manually allocating a new one,
1014 (pic16_assignRegisters): now before going through the register
1015 allocating functions mark all registers as free. This eliminates some
1016 side effects resulting from peephole parser done earlier in the backbone
1018 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1020 * src/SDCCicode.c (geniCodeLogic),

1076 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1077 which dumps before the function entry point a data byte which represents
1078 the number of the local variables used by the specified function, added
1079 'xinst' for initial support for Extended Instruction Support,
1080 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1081 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1082 port->fun_prefix anymore (may change later),
1083 (genFunction, genEndFunction): do not store/restore local registers for
1084 _main (this should take care the --main-return command line option in
1086 (genOr): removed some legacy pic-port instructions,
1087 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1088 performing operations with SFR's causes data to be written more than
1089 once to each SFR. Perhaps SFRs should be handled in special cases...
1090 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1092 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1095 --extended or -y for Extended Instruction Support,
1096 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1097 (deassignLRs): *** perhaps the most important change, old 'for' code
1098 (commented out for reference), didn't account for some registers which
1099 were left marked 'not free' after a pointer operation. The change
1100 reduces register usage a lot in some cases

3481 * (struct resolvedIfx) is moved to gen.h and made public,
3482 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3483 * (aopForSym): added an optimization to directly store in stack of
3484 the operand of a SEND iCode,
3485 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3486 but as registers instead (AOP_REG) using the fReturnIdx array,
3487 * (pic16_freeAsmop): remove the freed register from the
3488 _G.sregsAlloc field,
3489 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3490 a compare of 'WREG',
3491 * (pic16_popGetTempRegCond): changed function prototype, now
3492 function takes also a bitVector argument v which holds the current
3493 set of registers that are allocated for stack access by aopForSym,
3494 registers allocated in aopForSym for accessing stack symbols are not
3495 any more part of the functions usedRegs field,
3496 * (genCall): some times aopOp is called for a stack variable to be
3497 send, aopForSym might perform the push, if this is true make sure
3498 that genCall doesn't push the variable twice by testing _G.resDirect,
3499 * (genFunction): changed testing for unspecified interrupt number
3500 from 256 to INTNO_UNSPEC,
3501 * modified selection scheme of frame pointer generation. Previously
3502 if function did use local registers a frame pointer was generated,
3503 now a frame pointer is generated only if function has arguments
3504 (that need PLUSW2 register access), or has stack arguments, or the
3505 compiler is not instructed to omit the frame pointer,
3506 * (genEndFunction): before restoring local registers that were saved
3507 in the function preamble, also restore the registers that *might*
3508 have been allocated for stack access,
3509 * (genRet): removed some old comments,
3510 * (genCmp, the active (RN's) version): added a call to the
3511 pic16_genCmp_special function to perform the compare with a more
3512 robust and optimized way,
3513 * (genInline): a feature has been added in inline code generation,
3514 which allows a wildcard variable substitution when writing inline
3515 assembly. Code is incomplete and experimental therefore undocumented,
3516 * (genCast): changed order of aopOp for result and right to allow
3517 aopForSym to directly load the result if possible,
3518 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3519 perform an optimized compare on some selected special occasions,
3520 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3521 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3522 generate an IVT any more,
3523 * src/pic16/main.c (pic16_optionsTable): added command line option
3525 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3526 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3528 * src/pic16/NOTES: Raphael Neider added in list of active developers
3529 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3530 jumptable_end to prevent bug #,
3531 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3532 inCond and outCond fields,
3533 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3534 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3535 turn off register spilling,
3536 * (packRegsForOneUse): synced with other ports' versions although it
3537 is not used currently,
3538 * (pic16_packRegisters): added an optimization while reading
3539 structure bitfields, some registers may be saved (malloc code is
3540 decreased by 80 bytes)
3542 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3544 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3545 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3546 this can be optimized more?
3548 2005-03-10 Raphael Neider <rneider AT web.de>
3550 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3551 genNearPointerGet): (hopefully) fixed access to bitfields via
3552 pointers (p->bitN = x; and x = p->bitN; failed)

3878 access stack and frame pointers. They are initially assigned to
3879 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3880 accessing SFRs. Updated all occurences of modification of stack or
3881 frame pointer in gen.c and pcode.c,

4187 generated for switch statements. For now you need to set the
4188 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4189 Now 4 algorithms for mcs51 jumptable generation are used:
4190 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4224 * added libc directory. The current version of LibC contains string
4225 functions, ctype functions and macros and some functions of the
4226 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4227 be extensively tested in the future. Standard disclaimer here.

4241 * (genCmp): experimental code for new genCmp which uses PIC18's
4242 special compare&skip instructions. Initial tests fail some times
4243 with variables grater than 1 byte in size, so new code is disabled,
4244 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4246 * (genCast): began a fix to optimize the casting of a bit to another
4247 bit, now assigning a bitfield to another bitfield will fail, sorry,

4262 * src/pic16/ralloc.c (allocReg): add preliminary support for
4263 supporting a limited set of temporary registers,

7273 loaded with the linker search paths (-L arguments) and the libraries
7274 to be linked with the current source (-l arguments). Changes
7275 currently will affect only the pic16 port.
7276 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7277 include path the port specific paths and port specific libraries,
7278 * gplink command now contains the $3 argument,
7279 * src/pic16/device.h,
7280 * src/pic16/device.c,: structure PIC_device is made public and
7281 renamed to PIC16_device, the same for variable Pics which is renamed

7296 Documenting changes from previous commits.
7297 * configure.in (version 1.56),
7298 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7299 when generating output files to configure the pic16 library,
7300 but now I've commented it out, since gputils aren't installed in the
7301 SF compile farm, so library won't compile
7303 * device/lib/Makefile.in (version 1.56): initially I've added in
7304 target 'all' the prerequestive 'model-pic16' so it compiled the
7305 pic16 library, but now I've commented it out for the same reasons
7307 * added targets 'model-pic16' and 'objects-pic16' to compile the
7309 * added target 'port-specific-objects-pic16' to handle the
7310 generated libraries and copy them into the build/ directory
7311 * added target 'clean-intermediate-pic16' to clean intermediate
7312 files into pic16 directory
7313 * in target 'installdirs' added line to create directory pic16 in

7335 option so that it actually works. Made it specific to the z80, since
7336 the gbz80 doesn't have these kinds of I/O ports.
7338 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7562 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7564 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7565 (default behaviour).
7567 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7569 A python script to validate compiler diagnostic messages. It can be
7570 used to verify that sdcc complains about bad c source code and
7571 gives a good location of the error.
7572 * support/valdiag/Makefile,
7573 * support/valdiag/valdiag.py,
7574 * support/valdiag/tests/*

7591 Bug reported from Jesus Calvino-Fraga
7593 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7595 * sdcc.spec: updated
7596 * device/include/Makefile.in: don't install CVS directories
7597 * device/lib/Makefile.in: added removal of CVS directories after install
7598 * doc/Makefile: fixed install, added local_icons
7599 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7600 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7601 * src/ds390/gen.c (genRightShift): fixed bug #870788
7602 * src/SDCCast.c (decorateType): fixed bug #870781
7604 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7606 PIC16 port related changes:
7607 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7608 added variable stackPos,
7610 * gen.c: genCall, assignResultValue: added support for
7611 pushing/retrieving function parameters to/from stack,
7612 genFunction,genEndFunction: setup stack frame for the
7614 genAddrOf: will be changed according to bug 863624
7616 * added files genutils.c and genutils.h which contain gen*
7617 debugged and optimised functions extracted from gen.c
7619 * glue.c: added variable 'externs' which holds extern symbols,
7620 pic16emitRegularMap: is modified to properly handle relocatable
7621 symbols under the new scheme,
7622 pic16createInterruptVect: is modified
7623 pic16printPublics: is modified to emit 'global' assembler directives,
7624 added pic16_printExterns to print extern symbols,
7625 pic16glue: initializes stack/frame pointer in the beginning of
7626 the assembly output. Temporary hack, will be corrected later,
7627 because gplink yet does not support stack and SDCC does not
7628 yet support a type of crt0.o object to create the final binary.
7630 * Removed many lines that contain 8051 legacy code.
7631 * The code is finally placed under a 'code' directive.
7632 * Added port specific options.
7634 * _process_pragma: simplified since now we do not need *special*
7635 include file to define SFR registers. But a separate header
7636 will be needed. This will be developed later.
7637 * _pic16_parseOptions: added, parses port specific options:
7638 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7639 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7640 --preplace-udata-with=
7642 * _pic16_setDefaultOptions: modified to initialize section names,
7643 but hack is temporarly out of order since it needs improvement.
7644 * _pic16_genAssemblerPreamble: configuration words are emitted by
7645 their address instead of their name. This part is incomplete and
7646 supports only the 18Fxx2 devices. Other devices will emit an error
7647 during assembly since they do not contain the same set of config
7649 * _pic16_genIVT: is modified,
7651 * pcode.c: added definitions for some hardware registers that are needed
7653 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7654 All PCI entries are updated. Now LFSR is supported.
7655 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7656 * added pic16_newpCodeOpLit2 to support instructions with
7657 two literal arguments
7658 * pic16_pCode2str: corrected code that emits assembler instructions
7659 with two literal operands and those that have an access bit modifier
7660 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7661 this fixes a bug which caused some labels to be lost, when an
7662 assembler directive was added, i.e. banksel,
7663 * pic16_FixRegisterBanking: improved logic that causes the insertion
7665 * InlineFunction: functions that are called once, are not any more
7666 inlined. This can be a port option in the future,
7668 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7670 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7671 hold the corresponding uninitialized symbols,
7672 * pic16_allocProcessorRegister: registers have explicit marked the
7674 * pic16_allocInternalRegister: registers are explicit marked as
7676 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7677 processing list, so bit registers were lost,
7680 * ralloc.h: added field 'accessBank' and original symbol operand
7681 in register definition,
7682 * removed the field isMapped from register definition,
7684 ** Several functions have been removed from various sources:
7685 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7686 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7687 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7688 pic16_assignRelocatableRegisters
7690 ** others have been introduced:
7691 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7692 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7694 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7696 * support/scripts/inc2h.pl: changed definition of BIT_AT
7697 to emit 'sbit at' instead of 'bit at'. This was a request.
7699 PIC16 port related preliminary changes:
7700 * gen.c: prefixed function popRegFromString with
7701 pic16_ and all references to it corrected
7702 * pcode.c: all pic16_pc_* hardware registers prefixed
7703 with underscore (_),
7704 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7705 * ralloc.c: newReg(): when register is REG_SFR then
7706 set address to rIdx,
7707 pic16_allocProcessorRegister(): marks register wasUsed=0
7708 pic16_writeUsedRegs(): added a call to assign processor
7709 registers via pic16_assignFixedRegisters
7711 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7713 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7714 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7715 variables in unused register banks. Also the SSEG is placed
7716 wherever there is enough space for it, and IDATA can be anywhere
7717 in internal RAM. For now compile using -Wl-Y[stack_size].
7718 The mem file is different for this option as well, since it
7719 makes no sense of talking about DSEG lenght.
7721 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7723 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7724 in certain cases, e.g. when ROM assignment, patch provided
7725 from Albert den Haan.
7727 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8633 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8635 Fixed bug #621531 (const & volatile confusion in the type chain).
8636 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8729 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8730 fetching of the pointer
8731 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8732 copied from genNearPointerSet()
8733 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8734 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8735 If they pop r0/r1 they must be called in the opposite order than aopOp().
8736 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8737 (resp. --stack-auto), prepared for --xstack

8748 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8750 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8751 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8752 type for bits was changed. It resulted in bit variables becoming
8753 global, which is not permitted in PIC 14 assembly output.
8755 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8757 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8770 A few small changes that speed up the peephole optimizer.
8774 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8776 Try to make the peephole optimizer smarter by maintaining
8777 an association between the assembly source code and the
8778 iCodes that originated them. Put this information to use
8779 with a new peephole rule condition "notVolatile" so that
8780 the rules can be aggressive yet still safe.
8785 * src/mcs51/peeph.def
8787 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8791 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8792 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8793 if the left or right operand symbols have the accuse flag set.
8795 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8797 Changed the type of the result of the ! (NOT) operator to char;
8798 previously it returned the same type as the source. This allows
8799 us to eliminate all the genFloatNot functions (all of its target
8800 implementations were very buggy) since !float can use the same
8803 * src/SDCCicode.c (ast2iCode): ! returns char
8804 * src/mcs51/gen.c (genNot, genNotFloat),
8805 * src/ds390/gen.c (genNot, genNotFloat),
8806 * src/z80/gen.c (genNot, genNotFloat),
8807 * src/pic/gen.c (genNot, genNotFloat),

8810 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8812 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8813 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8814 during interrupts. Ensure WSAVE is located at a shared bank address.
8815 2. Fixed page selection in some places
8816 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8817 the registers name strings.
8818 4. Fixed "signed / unsigned compare" compiler warnings.
8819 5. The PIC port manages its own allocation of the general purpose
8820 registers, but makes no attempt to reuse them. As a result when
8821 compiling it soon runs out of general purpose registers. Some
8822 additional code was added to the files pcode.c and device.c to walk
8823 through the function call tree and rename the registers so that they
8833 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8834 genPlus() & genMinus() when the result is the same as left or right
8836 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8840 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8842 Made bitfield a distinct type from bit so that bitfields
8843 convert as per ANSI C and bits retain their traditional
8844 boolean style behaviour. Implemented bitfield support in
8852 * src/ds390/gen.c: bit v bitfield split
8853 * src/z80/gen.c: New support for bitfields
8854 * support/regression/tests/bitfields.c: reenabled z80,
8857 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8859 Rules 246.x, 247.x relate to bitfields, the others speed up
8860 access to xdata mapped I/O devices.
8862 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8864 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8866 Cleaned up genPackBits and genUnpackBits and added two helper
8867 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8868 for literal assignments in genPackBits (thanks to Frieder for
8874 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8876 Fixed bug #748310 (pointer to function type mishandled when the
8877 function name is omitted). Also fixed a SIGSEGV when a function
8878 attribute (reentrant, etc) is used on a non-function or on a
8879 function but misplaced before the parameter list.
8881 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8883 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8884 * support/Util/SDCCerr.h,
8885 * support/Util/SDCCerr.c: Added func attr misuse error msg

8906 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8908 Made the constant following the "interrupt" keyword optional. If
8909 omitted, the function will not automatically be given an entry
8910 in the interrupt vector table (similar to #pragma NOIV, but
8911 less syntacticly kludgy). The interrupt number is also now
8912 range checked. Also fixed a bug in the high order bit example

8926 * src/SDCCicode.c (operandOperation): rewritten some ops
8927 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8928 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8930 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8931 be re-activated by defining REDUCE_LITERALS)
8932 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8933 unsigned, but are signed by default
8934 * src/SDCCval.c (constVal): rearranged
8935 * src/SDCCval.c (valMod): preliminary fix
8936 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9443 messages from optionsTable when a port is not configured, added
9444 support for the PIc16 port in the ports table, when executing
9445 the compiler with no port specified on command line, a default
9446 port is selected with the new macro DEFAULT_PORT which is
9447 defined in port.h, in setDefaultOptions() linkOptions is removed
9448 from initialization assignment, since now it is a set,
9449 parseCmdLine uses setParseWithComma for linkOptions, in
9450 linkEdit() linkOptions are accessed with new function indexSet()
9451 which returns the i'th item of a set variable. See SDCCset.c, in
9452 linkEdit() when calling buildCmdLine(), added linkOptions as
9453 last argument. Now users can pass arguments to gplink via the
9454 -Wl option, main() uses pic16glue() to glue up pic16 programs

9468 gpasm complaining and test the linkage with gplink, _linkCmd and
9469 _asmCmd changed to be more gplink and gpasm friendly
9470 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9471 produced an error when parsed, peep rule 12 is added to utilize
9472 movff, but it is commented out since the pCode does not support
9473 yet a command with 2 address arguments
9475 2003-05-18 <johan AT balder>
9477 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9504 2003-05-11 Borut Razem <borut.razem AT siol.net>
9506 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10536 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10538 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10540 * in \sdcc\as\mcs51\ changed these files in order to create an
10541 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10542 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10543 following files to include the previous two files: aslink.dsp,
10544 Makefile.aslink, Makefile.bcc, and Makefile.in.
10546 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10547 .adb instead of .cdb
10549 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10551 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10552 value from option --iram-size.
10554 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10556 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10559 2002-09-18 <wiml AT hhhh.org>
10561 * SDCClrange.h: exposed setFromRange() and setToRange()
10562 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10563 packRegsForAccUse() (bug 542397)
10564 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10565 multiple times and emitting the fetch operations more than once
10566 added aopGetUsesAcc() function to allow binary operators to
10567 fetch their operands in the correct order; made genMinus() emit
10568 compact code for X = LITERAL - Y
10570 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10571 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10572 sprintf() in line 1267.
10574 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10575 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10578 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10579 Changes to aslink (All the changes are marked with 'JCF'):
10581 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10584 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10585 area BSEG. Also moves, if possible, the DATA area down into the internal
10586 ram so more space is available.
10588 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10591 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10592 not bytes. Function summary() which creates a memory usage summary
10593 file with extension .mem. Reports of overlaping stack and small stack
10594 size. If the space for the stack is less than 16 bytes aslink trows a
10597 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10598 the 8051. Option 'y' for memory summary output file.
10600 Changes to sdcc (All the changes are marked with 'JCF'):
10602 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10604 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10605 overlaying area for it (uses RegBankUsed[4]).
10607 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10608 bank zero as used by default. By default aslink locates the stack
10609 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10610 the creation of the .mem file. Delegates the allocation of data area
10611 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10612 the begining of the stack area to aslink.
10614 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10615 glue() in SDCCglue.c creates an area for it.
10617 2002-09-03 Borut Razem <borut.razem AT siol.net>
10618 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10619 sdcc/src/pic/glue.c:
10620 introduced atexit() handler for teporay files removal in case of
10621 errors, assertions, ...
10623 2002-08-29 Borut Razem <borut.razem AT siol.net>
10624 * sdcc/support/cpp2/auto-host_vc_in.h:
10625 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10626 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10627 Maybe there is a similar problem with BORLANDC? It should be checked!
10629 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10630 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10631 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10632 was not executed, and the compiler (cl) launched a warning:
10633 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10635 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10636 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10638 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10639 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10641 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10642 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10643 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10644 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10645 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10646 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10647 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10648 - added Release configuration in VS projects
10649 - review of compiler an linker options
10650 - VC .exe files are generated in bin_vc directory, not to interfere
10651 with binaries generated from other projects (cygwin, mingw, bcc ...)
10653 * sdcc/src/yacc.dsp: added
10655 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10656 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10657 and insert the version number definitions from .version
10659 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10661 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10662 added - genarate auto-host.h using auto-host_vc_in.h as template
10665 removed from CVS, generated automatically
10667 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10668 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10670 2002-08-11 Borut Razem <borut.razem AT siol.net>
10671 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10673 2002-08-10 Borut Razem <borut.razem AT siol.net>
10674 * src/SDCCmain.c (main):
10675 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10676 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10677 The consequence was that some temporary files were not removed.
10680 unification of code in functions tempfilename() and tempfile():
10681 function tempnam() is defined in Visual Studio 6.0 and .NET
10683 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10685 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10686 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10687 - removed compiler command line option /WX: Treats all warnings as errors
10688 - update a list of source files, included into the project
10690 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10691 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10692 changed project type to Generic Project so that can be correcly converted to VS.NET project
10694 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10696 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10698 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10700 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10701 added return 0 statements after assert() to make compiler happy
10703 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10704 added newline in the def file to keep MSC compiler satisfied
10706 * sdcc/src/z80/gen.c:
10707 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10708 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10709 - solved MSC error in function aopDump()
10711 * sdcc_vc.h: define PREFIX as "\\sdcc"
10713 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10753 2002-03-28 Johan Knol <johan AT balder>
10755 * src/SDCCval.c: fixed bug #532436
10757 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10759 Added "char *Processor" field to the port structure.
10762 Added -p option. Allows port dependent processor to be specified.
10765 Initialized the new field char *Processor field to NULL in all ports
10768 Compiler generated registers for interrupt context saving
10769 were not getting allocated.
10771 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10774 Fixed left shift. Will promote the left side of a left shift
10775 if a) left shifting more than size of operand or b) when assigned
10776 to something size > size of left side
10778 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10780 tons of changes. Register allocation has been
10781 rewritten. Added customization for the various PICs. Flow
10782 analysis is restructured. ...
10784 * src/pic/device.h:
10787 * src/pic/device.c:
10788 Added. device.c is a PIC port hack to accomodate variations
10791 2002-03-13 Michael Hope <michaelh AT vroom>
10793 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10795 2002-03-04 johanknol <johanknol AT manik>
10797 * /src/SDCCval.c: fixed
10799 const unsigned char arr[][2] = { { 0, 1 } };
10800 t18.c:1: error: Initializer element is not constant

10889 Previous fix was not good. basic blocks that have "break" or "return" are
10890 not really partof a loop , but live ranges used in these blocks should
