700 Enabled VPATH feature: changed nearly all Makefiles (149 files).
701 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
703 One basic decision: e.g. src/clean.mk includes further files. In order
704 to make this work there are two solutions:
705 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
706 run configure on them. This way they can use
707 'include $(srcdir)/port-clean.mk'
708 - always include clean.mk by the Makefile at the same level. To avoid
709 that `make clean` tries to include and build Makefile.dep the
710 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
711 implemented, because now even `make uninstall` doesn't create
712 Makefile.in. clean.mk could be eliminated by pasting it in
715 * debugger/mcs51/Makefile.in: build own objects from library sources
716 (SLIB, SDCC) in current directory
718 * configure, configure.in: renamed --disable-device-lib-build in
719 --disable-device-lib; added --enable-doc, the required tools are
720 searched by configure; added result message; the toolchain for the
721 belonging ports are now only built, if the port is enabled.
723 * support/regression/*: all output is written in directory gen, because
724 the fwk and ports directories don't livet in the build tree using vpath
726 * doc/sdccman.lyx: renamed --disable-device-lib-build to
727 --disable-device-lib, added --enable-doc, added section VPATH
729 * sim/ucsim/configure.in,
730 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
731 z80 are enabled by default
733 2006-04-24 Raphael Neider <rneider AT web.de>
735 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
736 to config word, "pic14_"-prefixed some extern functions
737 (pic14_emitConfigWord): emit __config directive(s) if assignment to
738 config word has been found
739 * src/pic/device.h: added prototypes
740 * src/pic/pcode.c: added "pic14_"-prefix where needed
741 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
743 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

990 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
992 * src/SDCCpeeph.c (operandsLiteral): new, added,
993 (callFuncByName): inserted operandsLiteral

1003 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1004 implemented patch 1120823 Thanks to Willy De la Court (normal
1005 interrupts need an interrupt number now if they are made critical),
1006 and enabled nesting of critical functions though not for gbz80
1007 (genCritical, genEndCritical): added functions
1008 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1009 * src/z80/mappings.i: added "ei" to all mappings
1011 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1013 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1014 submitted by the Debian SDCC maintainer Aurelien Jarno:
1015 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1016 archive with gcc 4.1 on mips and wrote the patch"
1018 2006-03-16 Raphael Neider <rneider AT web.de>
1020 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1021 the left operand is shorter than the result (c* = lit-c* + int),
1023 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1026 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1028 * src/.version: increased version number to 2.5.5
1029 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1030 linking is done manually in pic16 port's _linkEdit,
1031 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1032 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1033 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1034 allocate asmop as AOP_ACC,
1035 (aopForRemat): added parameter 'bool result' in function declaration,
1036 (pic16_aopGet): return AOP_ACC when accessing WREG,
1037 (pic16_popGetTempReg): minor modification,
1038 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1039 'pic16_allocWithIdx',
1040 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1041 calling function in absolute addresses,
1042 (genAssign): take into account AOP_ACC asmop,
1043 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1044 * src/pic16/pcoderegs.c: some debug functions and lines added,
1045 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1046 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1048 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1049 call to allocReg, not by manually allocating a new one,
1050 (pic16_assignRegisters): now before going through the register
1051 allocating functions mark all registers as free. This eliminates some
1052 side effects resulting from peephole parser done earlier in the backbone
1054 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1056 * src/SDCCicode.c (geniCodeLogic),

1075 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1076 (aopForSym, aopOp): increment asmop.allocated if reused,
1077 (freeAsmop): decrement asmop.allocated and check for zero instead of
1079 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1080 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1081 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1104 2006-03-06 Borut Razem <borut.razem AT siol.net>
1106 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1107 made the linker quiet
1109 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1111 * src/pic16/gen.c (genPcall): fixed bug #1443644
1112 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1113 which dumps before the function entry point a data byte which represents
1114 the number of the local variables used by the specified function, added
1115 'xinst' for initial support for Extended Instruction Support,
1116 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1117 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1118 port->fun_prefix anymore (may change later),
1119 (genFunction, genEndFunction): do not store/restore local registers for
1120 _main (this should take care the --main-return command line option in
1122 (genOr): removed some legacy pic-port instructions,
1123 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1124 performing operations with SFR's causes data to be written more than
1125 once to each SFR. Perhaps SFRs should be handled in special cases...
1126 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1128 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1129 into account for stack starting position,
1130 (struct OPTIONS pic16_optionsTable): added command line argument
1131 --extended or -y for Extended Instruction Support,
1132 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1133 (deassignLRs): *** perhaps the most important change, old 'for' code
1134 (commented out for reference), didn't account for some registers which
1135 were left marked 'not free' after a pointer operation. The change
1136 reduces register usage a lot in some cases
1138 2006-03-04 Borut Razem <borut.razem AT siol.net>
1140 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3483 * device/lib/printf_fast.c,
3484 * device/lib/printf_tiny.c: updated comments
3486 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3488 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3491 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3493 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3494 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3496 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3498 * device/lib/printf_large.c: removed inline assembly for portability and
3499 readability. Use printf_fast if speed or size are more important.
3500 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3501 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3503 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3505 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3506 prevent compiler warning
3508 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3510 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3511 moved to level 0 and declared as static. Also they are explicit
3512 placed in access bank. This was necessery because some times they
3513 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3514 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3515 optimizations. Currently only compare to unsigned char is implemented,
3516 * src/pic16/gen.c: added fReturnIdx array,
3517 * (struct resolvedIfx) is moved to gen.h and made public,
3518 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3519 * (aopForSym): added an optimization to directly store in stack of
3520 the operand of a SEND iCode,
3521 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3522 but as registers instead (AOP_REG) using the fReturnIdx array,
3523 * (pic16_freeAsmop): remove the freed register from the
3524 _G.sregsAlloc field,
3525 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3526 a compare of 'WREG',
3527 * (pic16_popGetTempRegCond): changed function prototype, now
3528 function takes also a bitVector argument v which holds the current
3529 set of registers that are allocated for stack access by aopForSym,
3530 registers allocated in aopForSym for accessing stack symbols are not
3531 any more part of the functions usedRegs field,
3532 * (genCall): some times aopOp is called for a stack variable to be
3533 send, aopForSym might perform the push, if this is true make sure
3534 that genCall doesn't push the variable twice by testing _G.resDirect,
3535 * (genFunction): changed testing for unspecified interrupt number
3536 from 256 to INTNO_UNSPEC,
3537 * modified selection scheme of frame pointer generation. Previously
3538 if function did use local registers a frame pointer was generated,
3539 now a frame pointer is generated only if function has arguments
3540 (that need PLUSW2 register access), or has stack arguments, or the
3541 compiler is not instructed to omit the frame pointer,
3542 * (genEndFunction): before restoring local registers that were saved
3543 in the function preamble, also restore the registers that *might*
3544 have been allocated for stack access,
3545 * (genRet): removed some old comments,
3546 * (genCmp, the active (RN's) version): added a call to the
3547 pic16_genCmp_special function to perform the compare with a more
3548 robust and optimized way,
3549 * (genInline): a feature has been added in inline code generation,
3550 which allows a wildcard variable substitution when writing inline
3551 assembly. Code is incomplete and experimental therefore undocumented,
3552 * (genCast): changed order of aopOp for result and right to allow
3553 aopForSym to directly load the result if possible,
3554 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3555 perform an optimized compare on some selected special occasions,
3556 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3557 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3558 generate an IVT any more,
3559 * src/pic16/main.c (pic16_optionsTable): added command line option
3561 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3562 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3564 * src/pic16/NOTES: Raphael Neider added in list of active developers
3565 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3566 jumptable_end to prevent bug #,
3567 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3568 inCond and outCond fields,
3569 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3570 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3571 turn off register spilling,
3572 * (packRegsForOneUse): synced with other ports' versions although it
3573 is not used currently,
3574 * (pic16_packRegisters): added an optimization while reading
3575 structure bitfields, some registers may be saved (malloc code is
3576 decreased by 80 bytes)
3578 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3580 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3581 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3582 this can be optimized more?
3584 2005-03-10 Raphael Neider <rneider AT web.de>
3586 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3587 genNearPointerGet): (hopefully) fixed access to bitfields via
3588 pointers (p->bitN = x; and x = p->bitN; failed)
3590 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3631 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3633 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3634 to keep the correct label reference count when adding/removing references
3635 to labels. A peephole file using this is appended to patch #1144962.

3871 copy the third byte from the int -- now assumes 0x80 (data memory)
3872 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
3873 operands (genAddLit expects the iCode's operands to swapped as

3913 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
3914 access stack and frame pointers. They are initially assigned to
3915 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3916 accessing SFRs. Updated all occurences of modification of stack or
3917 frame pointer in gen.c and pcode.c,

4222 Adding support for replacing ljmps with sjmps in jumptables
4223 generated for switch statements. For now you need to set the
4224 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4225 Now 4 algorithms for mcs51 jumptable generation are used:
4226 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4227 addresses loaded pc-relative for up to 112 cases and stack-pushing
4228 target addresses loaded with offset from dptr for up to 256 cases.

4260 * added libc directory. The current version of LibC contains string
4261 functions, ctype functions and macros and some functions of the
4262 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4263 be extensively tested in the future. Standard disclaimer here.

4276 * (pic16_storeForReturn): optimized return of 0,
4277 * (genCmp): experimental code for new genCmp which uses PIC18's
4278 special compare&skip instructions. Initial tests fail some times
4279 with variables grater than 1 byte in size, so new code is disabled,
4280 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4282 * (genCast): began a fix to optimize the casting of a bit to another
4283 bit, now assigning a bitfield to another bitfield will fail, sorry,

4297 registers when it shouldn't,
4298 * src/pic16/ralloc.c (allocReg): add preliminary support for
4299 supporting a limited set of temporary registers,
4301 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7308 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7309 loaded with the linker search paths (-L arguments) and the libraries
7310 to be linked with the current source (-l arguments). Changes
7311 currently will affect only the pic16 port.
7312 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7313 include path the port specific paths and port specific libraries,
7314 * gplink command now contains the $3 argument,
7315 * src/pic16/device.h,
7316 * src/pic16/device.c,: structure PIC_device is made public and

7332 Documenting changes from previous commits.
7333 * configure.in (version 1.56),
7334 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7335 when generating output files to configure the pic16 library,
7336 but now I've commented it out, since gputils aren't installed in the
7337 SF compile farm, so library won't compile
7339 * device/lib/Makefile.in (version 1.56): initially I've added in
7340 target 'all' the prerequestive 'model-pic16' so it compiled the
7341 pic16 library, but now I've commented it out for the same reasons
7343 * added targets 'model-pic16' and 'objects-pic16' to compile the
7345 * added target 'port-specific-objects-pic16' to handle the
7346 generated libraries and copy them into the build/ directory
7347 * added target 'clean-intermediate-pic16' to clean intermediate
7348 files into pic16 directory
7349 * in target 'installdirs' added line to create directory pic16 in
7350 the installation path

7353 added lines to copy all header files to installation path,
7354 * in target 'installdirs' added line create directory for pic16
7355 headers in the installation path

7371 option so that it actually works. Made it specific to the z80, since
7372 the gbz80 doesn't have these kinds of I/O ports.
7374 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7376 * device/include/z180.h,

7483 UPPER for immediate operands,
7484 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7486 * src/pic16/peeph.def: all peepholes with movff are commented out,
7487 because there is a problem in the pcode peep optimizer,
7488 * src/pic16/ralloc.c: the register allocator can now reuse local
7489 function symbols for another function. This saves register usage.
7490 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7492 Added file src/pic16/NOTES with information about program writing on

7598 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7600 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7601 (default behaviour).
7603 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7605 A python script to validate compiler diagnostic messages. It can be
7606 used to verify that sdcc complains about bad c source code and
7607 gives a good location of the error.
7608 * support/valdiag/Makefile,
7609 * support/valdiag/valdiag.py,

7629 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7631 * sdcc.spec: updated
7632 * device/include/Makefile.in: don't install CVS directories
7633 * device/lib/Makefile.in: added removal of CVS directories after install
7634 * doc/Makefile: fixed install, added local_icons
7635 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

7640 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7642 PIC16 port related changes:
7643 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7644 added variable stackPos,
7646 * gen.c: genCall, assignResultValue: added support for
7647 pushing/retrieving function parameters to/from stack,
7648 genFunction,genEndFunction: setup stack frame for the
7650 genAddrOf: will be changed according to bug 863624
7652 * added files genutils.c and genutils.h which contain gen*
7653 debugged and optimised functions extracted from gen.c
7655 * glue.c: added variable 'externs' which holds extern symbols,
7656 pic16emitRegularMap: is modified to properly handle relocatable
7657 symbols under the new scheme,
7658 pic16createInterruptVect: is modified
7659 pic16printPublics: is modified to emit 'global' assembler directives,
7660 added pic16_printExterns to print extern symbols,
7661 pic16glue: initializes stack/frame pointer in the beginning of
7662 the assembly output. Temporary hack, will be corrected later,
7663 because gplink yet does not support stack and SDCC does not
7664 yet support a type of crt0.o object to create the final binary.
7666 * Removed many lines that contain 8051 legacy code.
7667 * The code is finally placed under a 'code' directive.
7668 * Added port specific options.
7670 * _process_pragma: simplified since now we do not need *special*
7671 include file to define SFR registers. But a separate header
7672 will be needed. This will be developed later.
7673 * _pic16_parseOptions: added, parses port specific options:
7674 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7675 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7676 --preplace-udata-with=
7678 * _pic16_setDefaultOptions: modified to initialize section names,
7679 but hack is temporarly out of order since it needs improvement.
7680 * _pic16_genAssemblerPreamble: configuration words are emitted by
7681 their address instead of their name. This part is incomplete and
7682 supports only the 18Fxx2 devices. Other devices will emit an error
7683 during assembly since they do not contain the same set of config
7685 * _pic16_genIVT: is modified,
7687 * pcode.c: added definitions for some hardware registers that are needed
7689 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7690 All PCI entries are updated. Now LFSR is supported.
7691 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7692 * added pic16_newpCodeOpLit2 to support instructions with
7693 two literal arguments
7694 * pic16_pCode2str: corrected code that emits assembler instructions
7695 with two literal operands and those that have an access bit modifier
7696 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7697 this fixes a bug which caused some labels to be lost, when an
7698 assembler directive was added, i.e. banksel,
7699 * pic16_FixRegisterBanking: improved logic that causes the insertion
7701 * InlineFunction: functions that are called once, are not any more
7702 inlined. This can be a port option in the future,
7704 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7706 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7707 hold the corresponding uninitialized symbols,
7708 * pic16_allocProcessorRegister: registers have explicit marked the
7710 * pic16_allocInternalRegister: registers are explicit marked as
7712 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7713 processing list, so bit registers were lost,
7716 * ralloc.h: added field 'accessBank' and original symbol operand
7717 in register definition,
7718 * removed the field isMapped from register definition,
7720 ** Several functions have been removed from various sources:
7721 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7722 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7723 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7724 pic16_assignRelocatableRegisters
7726 ** others have been introduced:
7727 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7728 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7730 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7732 * support/scripts/inc2h.pl: changed definition of BIT_AT
7733 to emit 'sbit at' instead of 'bit at'. This was a request.
7735 PIC16 port related preliminary changes:
7736 * gen.c: prefixed function popRegFromString with
7737 pic16_ and all references to it corrected
7738 * pcode.c: all pic16_pc_* hardware registers prefixed
7739 with underscore (_),
7740 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7741 * ralloc.c: newReg(): when register is REG_SFR then
7742 set address to rIdx,
7743 pic16_allocProcessorRegister(): marks register wasUsed=0
7744 pic16_writeUsedRegs(): added a call to assign processor
7745 registers via pic16_assignFixedRegisters
7747 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7749 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7750 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7751 variables in unused register banks. Also the SSEG is placed
7752 wherever there is enough space for it, and IDATA can be anywhere
7753 in internal RAM. For now compile using -Wl-Y[stack_size].
7754 The mem file is different for this option as well, since it
7755 makes no sense of talking about DSEG lenght.
7757 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7759 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7760 in certain cases, e.g. when ROM assignment, patch provided
7761 from Albert den Haan.
7763 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8649 support for standard C idiom of memory mapped variables; for
8650 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8651 to xdata int at 0x1234 tempvar = 1.
8652 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8653 provided by Akiya ISHIDA

8764 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8765 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8766 fetching of the pointer
8767 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8768 copied from genNearPointerSet()
8769 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8770 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8771 If they pop r0/r1 they must be called in the opposite order than aopOp().

8784 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8786 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8787 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8788 type for bits was changed. It resulted in bit variables becoming
8789 global, which is not permitted in PIC 14 assembly output.
8791 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8806 A few small changes that speed up the peephole optimizer.
8810 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8812 Try to make the peephole optimizer smarter by maintaining
8813 an association between the assembly source code and the
8814 iCodes that originated them. Put this information to use
8815 with a new peephole rule condition "notVolatile" so that
8816 the rules can be aggressive yet still safe.
8821 * src/mcs51/peeph.def
8823 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8827 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8828 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8829 if the left or right operand symbols have the accuse flag set.
8831 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8833 Changed the type of the result of the ! (NOT) operator to char;
8834 previously it returned the same type as the source. This allows
8835 us to eliminate all the genFloatNot functions (all of its target
8836 implementations were very buggy) since !float can use the same

8848 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8849 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8850 during interrupts. Ensure WSAVE is located at a shared bank address.
8851 2. Fixed page selection in some places
8852 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8853 the registers name strings.
8854 4. Fixed "signed / unsigned compare" compiler warnings.
8855 5. The PIC port manages its own allocation of the general purpose
8856 registers, but makes no attempt to reuse them. As a result when
8857 compiling it soon runs out of general purpose registers. Some
8858 additional code was added to the files pcode.c and device.c to walk
8859 through the function call tree and rename the registers so that they
8869 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8870 genPlus() & genMinus() when the result is the same as left or right

8876 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8878 Made bitfield a distinct type from bit so that bitfields
8879 convert as per ANSI C and bits retain their traditional
8880 boolean style behaviour. Implemented bitfield support in
8888 * src/ds390/gen.c: bit v bitfield split
8889 * src/z80/gen.c: New support for bitfields
8890 * support/regression/tests/bitfields.c: reenabled z80,
8893 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8895 Rules 246.x, 247.x relate to bitfields, the others speed up
8896 access to xdata mapped I/O devices.
8898 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8900 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8902 Cleaned up genPackBits and genUnpackBits and added two helper
8903 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8904 for literal assignments in genPackBits (thanks to Frieder for
8910 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8912 Fixed bug #748310 (pointer to function type mishandled when the
8913 function name is omitted). Also fixed a SIGSEGV when a function
8914 attribute (reentrant, etc) is used on a non-function or on a
8915 function but misplaced before the parameter list.
8917 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8919 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8920 * support/Util/SDCCerr.h,

8942 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8944 Made the constant following the "interrupt" keyword optional. If
8945 omitted, the function will not automatically be given an entry
8946 in the interrupt vector table (similar to #pragma NOIV, but
8947 less syntacticly kludgy). The interrupt number is also now
8948 range checked. Also fixed a bug in the high order bit example

9478 added if/endif conditional macros to remove options help
9479 messages from optionsTable when a port is not configured, added
9480 support for the PIc16 port in the ports table, when executing
9481 the compiler with no port specified on command line, a default
9482 port is selected with the new macro DEFAULT_PORT which is
9483 defined in port.h, in setDefaultOptions() linkOptions is removed
9484 from initialization assignment, since now it is a set,
9485 parseCmdLine uses setParseWithComma for linkOptions, in
9486 linkEdit() linkOptions are accessed with new function indexSet()
9487 which returns the i'th item of a set variable. See SDCCset.c, in
9488 linkEdit() when calling buildCmdLine(), added linkOptions as
9489 last argument. Now users can pass arguments to gplink via the
9490 -Wl option, main() uses pic16glue() to glue up pic16 programs

9503 * src/pic16/main.c: __config directives are commented out to stop
9504 gpasm complaining and test the linkage with gplink, _linkCmd and
9505 _asmCmd changed to be more gplink and gpasm friendly
9506 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9507 produced an error when parsed, peep rule 12 is added to utilize
9508 movff, but it is commented out since the pCode does not support
9509 yet a command with 2 address arguments
9511 2003-05-18 <johan AT balder>
9513 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10568 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10569 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10571 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10572 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10574 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10576 * in \sdcc\as\mcs51\ changed these files in order to create an
10577 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10578 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10579 following files to include the previous two files: aslink.dsp,
10580 Makefile.aslink, Makefile.bcc, and Makefile.in.
10582 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10583 .adb instead of .cdb
10585 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10587 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10588 value from option --iram-size.
10590 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10592 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10595 2002-09-18 <wiml AT hhhh.org>
10597 * SDCClrange.h: exposed setFromRange() and setToRange()
10598 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10599 packRegsForAccUse() (bug 542397)
10600 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10601 multiple times and emitting the fetch operations more than once
10602 added aopGetUsesAcc() function to allow binary operators to
10603 fetch their operands in the correct order; made genMinus() emit
10604 compact code for X = LITERAL - Y
10606 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10607 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10608 sprintf() in line 1267.
10610 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10611 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10614 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10615 Changes to aslink (All the changes are marked with 'JCF'):
10617 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10620 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10621 area BSEG. Also moves, if possible, the DATA area down into the internal
10622 ram so more space is available.
10624 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10627 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10628 not bytes. Function summary() which creates a memory usage summary
10629 file with extension .mem. Reports of overlaping stack and small stack
10630 size. If the space for the stack is less than 16 bytes aslink trows a
10633 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10634 the 8051. Option 'y' for memory summary output file.
10636 Changes to sdcc (All the changes are marked with 'JCF'):
10638 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10640 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10641 overlaying area for it (uses RegBankUsed[4]).
10643 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10644 bank zero as used by default. By default aslink locates the stack
10645 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10646 the creation of the .mem file. Delegates the allocation of data area
10647 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10648 the begining of the stack area to aslink.
10650 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10651 glue() in SDCCglue.c creates an area for it.
10653 2002-09-03 Borut Razem <borut.razem AT siol.net>
10654 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10655 sdcc/src/pic/glue.c:
10656 introduced atexit() handler for teporay files removal in case of
10657 errors, assertions, ...
10659 2002-08-29 Borut Razem <borut.razem AT siol.net>
10660 * sdcc/support/cpp2/auto-host_vc_in.h:
10661 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10662 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10663 Maybe there is a similar problem with BORLANDC? It should be checked!
10665 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10666 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10667 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10668 was not executed, and the compiler (cl) launched a warning:
10669 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10671 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10672 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10674 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10675 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10677 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10678 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10679 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10680 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10681 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10682 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10683 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10684 - added Release configuration in VS projects
10685 - review of compiler an linker options
10686 - VC .exe files are generated in bin_vc directory, not to interfere
10687 with binaries generated from other projects (cygwin, mingw, bcc ...)
10689 * sdcc/src/yacc.dsp: added
10691 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10692 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10693 and insert the version number definitions from .version
10695 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10697 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10698 added - genarate auto-host.h using auto-host_vc_in.h as template
10701 removed from CVS, generated automatically
10703 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10704 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10706 2002-08-11 Borut Razem <borut.razem AT siol.net>
10707 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10709 2002-08-10 Borut Razem <borut.razem AT siol.net>
10710 * src/SDCCmain.c (main):
10711 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10712 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10713 The consequence was that some temporary files were not removed.
10716 unification of code in functions tempfilename() and tempfile():
10717 function tempnam() is defined in Visual Studio 6.0 and .NET
10719 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10721 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10722 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10723 - removed compiler command line option /WX: Treats all warnings as errors
10724 - update a list of source files, included into the project
10726 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10727 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10728 changed project type to Generic Project so that can be correcly converted to VS.NET project
10730 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10732 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10734 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10736 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10737 added return 0 statements after assert() to make compiler happy
10739 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10740 added newline in the def file to keep MSC compiler satisfied
10742 * sdcc/src/z80/gen.c:
10743 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10744 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10745 - solved MSC error in function aopDump()
10747 * sdcc_vc.h: define PREFIX as "\\sdcc"
10749 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10750 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10752 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10753 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10754 - Rewrote the register banking algorithm.
10755 - Added pCode live-range analysis to registers (for now, only non-used and
10756 singly-used registers optimized away)
10758 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10760 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
10762 2002-05-10 Scott Dattalo <scott AT dattalo.com>

10779 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10781 * src/z80/peeph.def: Added transpose redundent load rule.
10783 * src/z80/main.c: Added force callee saves for jaune.
10785 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10787 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10789 2002-03-28 Johan Knol <johan AT balder>
10791 * src/SDCCval.c: fixed bug #532436
10793 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10795 Added "char *Processor" field to the port structure.
10798 Added -p option. Allows port dependent processor to be specified.
10801 Initialized the new field char *Processor field to NULL in all ports
10804 Compiler generated registers for interrupt context saving
10805 were not getting allocated.
10807 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10810 Fixed left shift. Will promote the left side of a left shift
10811 if a) left shifting more than size of operand or b) when assigned
10812 to something size > size of left side
10814 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10816 tons of changes. Register allocation has been
10817 rewritten. Added customization for the various PICs. Flow
10818 analysis is restructured. ...
10820 * src/pic/device.h:
10823 * src/pic/device.c:
10824 Added. device.c is a PIC port hack to accomodate variations
10827 2002-03-13 Michael Hope <michaelh AT vroom>
10829 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
