686 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
688 Enabled VPATH feature: changed nearly all Makefiles (149 files).
689 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
691 One basic decision: e.g. src/clean.mk includes further files. In order
692 to make this work there are two solutions:
693 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
694 run configure on them. This way they can use
695 'include $(srcdir)/port-clean.mk'
696 - always include clean.mk by the Makefile at the same level. To avoid
697 that `make clean` tries to include and build Makefile.dep the
698 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
699 implemented, because now even `make uninstall` doesn't create
700 Makefile.in. clean.mk could be eliminated by pasting it in
703 * debugger/mcs51/Makefile.in: build own objects from library sources
704 (SLIB, SDCC) in current directory
706 * configure, configure.in: renamed --disable-device-lib-build in
707 --disable-device-lib; added --enable-doc, the required tools are
708 searched by configure; added result message; the toolchain for the
709 belonging ports are now only built, if the port is enabled.
711 * support/regression/*: all output is written in directory gen, because
712 the fwk and ports directories don't livet in the build tree using vpath
714 * doc/sdccman.lyx: renamed --disable-device-lib-build to
715 --disable-device-lib, added --enable-doc, added section VPATH
717 * sim/ucsim/configure.in,
718 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
719 z80 are enabled by default
721 2006-04-24 Raphael Neider <rneider AT web.de>
723 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
724 to config word, "pic14_"-prefixed some extern functions
725 (pic14_emitConfigWord): emit __config directive(s) if assignment to
726 config word has been found
727 * src/pic/device.h: added prototypes
728 * src/pic/pcode.c: added "pic14_"-prefix where needed
729 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
731 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
733 (pic14emitRegularMap): ignore config words,
734 (pic14createInterruptVect): moved generating __config directives away

978 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
980 * src/SDCCpeeph.c (operandsLiteral): new, added,
981 (callFuncByName): inserted operandsLiteral

991 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
992 implemented patch 1120823 Thanks to Willy De la Court (normal
993 interrupts need an interrupt number now if they are made critical),
994 and enabled nesting of critical functions though not for gbz80
995 (genCritical, genEndCritical): added functions
996 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
997 * src/z80/mappings.i: added "ei" to all mappings
999 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1002 submitted by the Debian SDCC maintainer Aurelien Jarno:
1003 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1004 archive with gcc 4.1 on mips and wrote the patch"
1006 2006-03-16 Raphael Neider <rneider AT web.de>
1008 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1009 the left operand is shorter than the result (c* = lit-c* + int),
1011 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1014 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1016 * src/.version: increased version number to 2.5.5
1017 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1018 linking is done manually in pic16 port's _linkEdit,
1019 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1020 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1021 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1022 allocate asmop as AOP_ACC,
1023 (aopForRemat): added parameter 'bool result' in function declaration,
1024 (pic16_aopGet): return AOP_ACC when accessing WREG,
1025 (pic16_popGetTempReg): minor modification,
1026 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1027 'pic16_allocWithIdx',
1028 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1029 calling function in absolute addresses,
1030 (genAssign): take into account AOP_ACC asmop,
1031 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1033 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1034 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1036 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1037 call to allocReg, not by manually allocating a new one,
1038 (pic16_assignRegisters): now before going through the register
1039 allocating functions mark all registers as free. This eliminates some
1040 side effects resulting from peephole parser done earlier in the backbone
1042 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1044 * src/SDCCicode.c (geniCodeLogic),

1063 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1064 (aopForSym, aopOp): increment asmop.allocated if reused,
1065 (freeAsmop): decrement asmop.allocated and check for zero instead of
1067 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1068 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1092 2006-03-06 Borut Razem <borut.razem AT siol.net>
1094 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1095 made the linker quiet
1097 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1099 * src/pic16/gen.c (genPcall): fixed bug #1443644
1100 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1101 which dumps before the function entry point a data byte which represents
1102 the number of the local variables used by the specified function, added
1103 'xinst' for initial support for Extended Instruction Support,
1104 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1105 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1106 port->fun_prefix anymore (may change later),
1107 (genFunction, genEndFunction): do not store/restore local registers for
1108 _main (this should take care the --main-return command line option in
1110 (genOr): removed some legacy pic-port instructions,
1111 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1112 performing operations with SFR's causes data to be written more than
1113 once to each SFR. Perhaps SFRs should be handled in special cases...
1114 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1116 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1117 into account for stack starting position,
1118 (struct OPTIONS pic16_optionsTable): added command line argument
1119 --extended or -y for Extended Instruction Support,
1120 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1121 (deassignLRs): *** perhaps the most important change, old 'for' code
1122 (commented out for reference), didn't account for some registers which
1123 were left marked 'not free' after a pointer operation. The change
1124 reduces register usage a lot in some cases
1126 2006-03-04 Borut Razem <borut.razem AT siol.net>
1128 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3486 * device/lib/printf_large.c: removed inline assembly for portability and
3487 readability. Use printf_fast if speed or size are more important.
3488 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3489 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3491 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3493 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3494 prevent compiler warning
3496 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3498 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3499 moved to level 0 and declared as static. Also they are explicit
3500 placed in access bank. This was necessery because some times they
3501 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3502 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3503 optimizations. Currently only compare to unsigned char is implemented,
3504 * src/pic16/gen.c: added fReturnIdx array,
3505 * (struct resolvedIfx) is moved to gen.h and made public,
3506 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3507 * (aopForSym): added an optimization to directly store in stack of
3508 the operand of a SEND iCode,
3509 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3510 but as registers instead (AOP_REG) using the fReturnIdx array,
3511 * (pic16_freeAsmop): remove the freed register from the
3512 _G.sregsAlloc field,
3513 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3514 a compare of 'WREG',
3515 * (pic16_popGetTempRegCond): changed function prototype, now
3516 function takes also a bitVector argument v which holds the current
3517 set of registers that are allocated for stack access by aopForSym,
3518 registers allocated in aopForSym for accessing stack symbols are not
3519 any more part of the functions usedRegs field,
3520 * (genCall): some times aopOp is called for a stack variable to be
3521 send, aopForSym might perform the push, if this is true make sure
3522 that genCall doesn't push the variable twice by testing _G.resDirect,
3523 * (genFunction): changed testing for unspecified interrupt number
3524 from 256 to INTNO_UNSPEC,
3525 * modified selection scheme of frame pointer generation. Previously
3526 if function did use local registers a frame pointer was generated,
3527 now a frame pointer is generated only if function has arguments
3528 (that need PLUSW2 register access), or has stack arguments, or the
3529 compiler is not instructed to omit the frame pointer,
3530 * (genEndFunction): before restoring local registers that were saved
3531 in the function preamble, also restore the registers that *might*
3532 have been allocated for stack access,
3533 * (genRet): removed some old comments,
3534 * (genCmp, the active (RN's) version): added a call to the
3535 pic16_genCmp_special function to perform the compare with a more
3536 robust and optimized way,
3537 * (genInline): a feature has been added in inline code generation,
3538 which allows a wildcard variable substitution when writing inline
3539 assembly. Code is incomplete and experimental therefore undocumented,
3540 * (genCast): changed order of aopOp for result and right to allow
3541 aopForSym to directly load the result if possible,
3542 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3543 perform an optimized compare on some selected special occasions,
3544 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3545 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3546 generate an IVT any more,
3547 * src/pic16/main.c (pic16_optionsTable): added command line option
3549 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3550 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3552 * src/pic16/NOTES: Raphael Neider added in list of active developers
3553 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3554 jumptable_end to prevent bug #,
3555 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3556 inCond and outCond fields,
3557 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3558 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3559 turn off register spilling,
3560 * (packRegsForOneUse): synced with other ports' versions although it
3561 is not used currently,
3562 * (pic16_packRegisters): added an optimization while reading
3563 structure bitfields, some registers may be saved (malloc code is
3564 decreased by 80 bytes)
3566 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3568 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3569 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3570 this can be optimized more?
3572 2005-03-10 Raphael Neider <rneider AT web.de>
3574 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3575 genNearPointerGet): (hopefully) fixed access to bitfields via
3576 pointers (p->bitN = x; and x = p->bitN; failed)
3578 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3580 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3621 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3622 to keep the correct label reference count when adding/removing references
3623 to labels. A peephole file using this is appended to patch #1144962.

3902 access stack and frame pointers. They are initially assigned to
3903 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3904 accessing SFRs. Updated all occurences of modification of stack or
3905 frame pointer in gen.c and pcode.c,
3906 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3907 assigning of a literal value to pointers,

4210 Adding support for replacing ljmps with sjmps in jumptables
4211 generated for switch statements. For now you need to set the
4212 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4213 Now 4 algorithms for mcs51 jumptable generation are used:
4214 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4215 addresses loaded pc-relative for up to 112 cases and stack-pushing
4216 target addresses loaded with offset from dptr for up to 256 cases.

4248 * added libc directory. The current version of LibC contains string
4249 functions, ctype functions and macros and some functions of the
4250 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4251 be extensively tested in the future. Standard disclaimer here.
4252 Library is not automatically build yet. But one can build it by
4253 invoking 'make' inside the libc directory.

4264 * (pic16_storeForReturn): optimized return of 0,
4265 * (genCmp): experimental code for new genCmp which uses PIC18's
4266 special compare&skip instructions. Initial tests fail some times
4267 with variables grater than 1 byte in size, so new code is disabled,
4268 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4270 * (genCast): began a fix to optimize the casting of a bit to another
4271 bit, now assigning a bitfield to another bitfield will fail, sorry,

4280 and 1 for banking instruction,
4281 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4282 caused stop processing pCodes after a inline assembly block,
4283 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4285 registers when it shouldn't,
4286 * src/pic16/ralloc.c (allocReg): add preliminary support for
4287 supporting a limited set of temporary registers,
4289 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7294 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7296 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7297 loaded with the linker search paths (-L arguments) and the libraries
7298 to be linked with the current source (-l arguments). Changes
7299 currently will affect only the pic16 port.
7300 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7301 include path the port specific paths and port specific libraries,
7302 * gplink command now contains the $3 argument,
7303 * src/pic16/device.h,
7304 * src/pic16/device.c,: structure PIC_device is made public and
7305 renamed to PIC16_device, the same for variable Pics which is renamed

7320 Documenting changes from previous commits.
7321 * configure.in (version 1.56),
7322 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7323 when generating output files to configure the pic16 library,
7324 but now I've commented it out, since gputils aren't installed in the
7325 SF compile farm, so library won't compile
7327 * device/lib/Makefile.in (version 1.56): initially I've added in
7328 target 'all' the prerequestive 'model-pic16' so it compiled the
7329 pic16 library, but now I've commented it out for the same reasons
7331 * added targets 'model-pic16' and 'objects-pic16' to compile the
7333 * added target 'port-specific-objects-pic16' to handle the
7334 generated libraries and copy them into the build/ directory
7335 * added target 'clean-intermediate-pic16' to clean intermediate
7336 files into pic16 directory
7337 * in target 'installdirs' added line to create directory pic16 in
7338 the installation path

7341 added lines to copy all header files to installation path,
7342 * in target 'installdirs' added line create directory for pic16
7343 headers in the installation path

7359 option so that it actually works. Made it specific to the z80, since
7360 the gbz80 doesn't have these kinds of I/O ports.
7362 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7364 * device/include/z180.h,

7388 via literal number. The symbol is placed in the corresponding
7389 position of the data ram
7390 * (pic16_dump_section): relocatable and absolute uninitialized
7391 data are now emitted in sorted order to reduce section naming,
7392 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7393 weren't marked as being in the access bank,

7470 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
7471 UPPER for immediate operands,
7472 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7474 * src/pic16/peeph.def: all peepholes with movff are commented out,
7475 because there is a problem in the pcode peep optimizer,
7476 * src/pic16/ralloc.c: the register allocator can now reuse local
7477 function symbols for another function. This saves register usage.
7478 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7480 Added file src/pic16/NOTES with information about program writing on
7481 the current port version.

7569 include information about variables allocated to the overlay
7572 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7574 * as/mcs51/lkmain.c: Help about -Y option

7584 LEFT_OP (left shift)
7586 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7588 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7589 (default behaviour).
7591 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7593 A python script to validate compiler diagnostic messages. It can be
7594 used to verify that sdcc complains about bad c source code and
7595 gives a good location of the error.
7596 * support/valdiag/Makefile,
7597 * support/valdiag/valdiag.py,
7598 * support/valdiag/tests/*
7600 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7615 Bug reported from Jesus Calvino-Fraga
7617 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7619 * sdcc.spec: updated
7620 * device/include/Makefile.in: don't install CVS directories
7621 * device/lib/Makefile.in: added removal of CVS directories after install
7622 * doc/Makefile: fixed install, added local_icons
7623 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7624 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7625 * src/ds390/gen.c (genRightShift): fixed bug #870788

7628 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7630 PIC16 port related changes:
7631 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7632 added variable stackPos,
7634 * gen.c: genCall, assignResultValue: added support for
7635 pushing/retrieving function parameters to/from stack,
7636 genFunction,genEndFunction: setup stack frame for the
7638 genAddrOf: will be changed according to bug 863624
7640 * added files genutils.c and genutils.h which contain gen*
7641 debugged and optimised functions extracted from gen.c
7643 * glue.c: added variable 'externs' which holds extern symbols,
7644 pic16emitRegularMap: is modified to properly handle relocatable
7645 symbols under the new scheme,
7646 pic16createInterruptVect: is modified
7647 pic16printPublics: is modified to emit 'global' assembler directives,
7648 added pic16_printExterns to print extern symbols,
7649 pic16glue: initializes stack/frame pointer in the beginning of
7650 the assembly output. Temporary hack, will be corrected later,
7651 because gplink yet does not support stack and SDCC does not
7652 yet support a type of crt0.o object to create the final binary.
7654 * Removed many lines that contain 8051 legacy code.
7655 * The code is finally placed under a 'code' directive.
7656 * Added port specific options.
7658 * _process_pragma: simplified since now we do not need *special*
7659 include file to define SFR registers. But a separate header
7660 will be needed. This will be developed later.
7661 * _pic16_parseOptions: added, parses port specific options:
7662 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7663 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7664 --preplace-udata-with=
7666 * _pic16_setDefaultOptions: modified to initialize section names,
7667 but hack is temporarly out of order since it needs improvement.
7668 * _pic16_genAssemblerPreamble: configuration words are emitted by
7669 their address instead of their name. This part is incomplete and
7670 supports only the 18Fxx2 devices. Other devices will emit an error
7671 during assembly since they do not contain the same set of config
7673 * _pic16_genIVT: is modified,
7675 * pcode.c: added definitions for some hardware registers that are needed
7677 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7678 All PCI entries are updated. Now LFSR is supported.
7679 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7680 * added pic16_newpCodeOpLit2 to support instructions with
7681 two literal arguments
7682 * pic16_pCode2str: corrected code that emits assembler instructions
7683 with two literal operands and those that have an access bit modifier
7684 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7685 this fixes a bug which caused some labels to be lost, when an
7686 assembler directive was added, i.e. banksel,
7687 * pic16_FixRegisterBanking: improved logic that causes the insertion
7689 * InlineFunction: functions that are called once, are not any more
7690 inlined. This can be a port option in the future,
7692 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7694 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7695 hold the corresponding uninitialized symbols,
7696 * pic16_allocProcessorRegister: registers have explicit marked the
7698 * pic16_allocInternalRegister: registers are explicit marked as
7700 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7701 processing list, so bit registers were lost,
7704 * ralloc.h: added field 'accessBank' and original symbol operand
7705 in register definition,
7706 * removed the field isMapped from register definition,
7708 ** Several functions have been removed from various sources:
7709 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7710 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7711 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7712 pic16_assignRelocatableRegisters
7714 ** others have been introduced:
7715 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7716 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7718 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7720 * support/scripts/inc2h.pl: changed definition of BIT_AT
7721 to emit 'sbit at' instead of 'bit at'. This was a request.
7723 PIC16 port related preliminary changes:
7724 * gen.c: prefixed function popRegFromString with
7725 pic16_ and all references to it corrected
7726 * pcode.c: all pic16_pc_* hardware registers prefixed
7727 with underscore (_),
7728 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7729 * ralloc.c: newReg(): when register is REG_SFR then
7730 set address to rIdx,
7731 pic16_allocProcessorRegister(): marks register wasUsed=0
7732 pic16_writeUsedRegs(): added a call to assign processor
7733 registers via pic16_assignFixedRegisters
7735 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7737 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7738 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7739 variables in unused register banks. Also the SSEG is placed
7740 wherever there is enough space for it, and IDATA can be anywhere
7741 in internal RAM. For now compile using -Wl-Y[stack_size].
7742 The mem file is different for this option as well, since it
7743 makes no sense of talking about DSEG lenght.
7745 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7747 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7748 in certain cases, e.g. when ROM assignment, patch provided
7749 from Albert den Haan.
7751 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8636 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8637 support for standard C idiom of memory mapped variables; for
8638 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8639 to xdata int at 0x1234 tempvar = 1.
8640 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8641 provided by Akiya ISHIDA

8657 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8659 Fixed bug #621531 (const & volatile confusion in the type chain).
8660 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8752 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8753 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8754 fetching of the pointer
8755 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8756 copied from genNearPointerSet()
8757 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8758 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8759 If they pop r0/r1 they must be called in the opposite order than aopOp().
8760 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8761 (resp. --stack-auto), prepared for --xstack

8770 these ports have their own __sdcc_external_start()
8772 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8774 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8775 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8776 type for bits was changed. It resulted in bit variables becoming
8777 global, which is not permitted in PIC 14 assembly output.
8779 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8781 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8794 A few small changes that speed up the peephole optimizer.
8798 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8800 Try to make the peephole optimizer smarter by maintaining
8801 an association between the assembly source code and the
8802 iCodes that originated them. Put this information to use
8803 with a new peephole rule condition "notVolatile" so that
8804 the rules can be aggressive yet still safe.
8809 * src/mcs51/peeph.def
8811 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8815 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8816 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8817 if the left or right operand symbols have the accuse flag set.
8819 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8821 Changed the type of the result of the ! (NOT) operator to char;
8822 previously it returned the same type as the source. This allows
8823 us to eliminate all the genFloatNot functions (all of its target
8824 implementations were very buggy) since !float can use the same
8827 * src/SDCCicode.c (ast2iCode): ! returns char

8834 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8836 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8837 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8838 during interrupts. Ensure WSAVE is located at a shared bank address.
8839 2. Fixed page selection in some places
8840 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8841 the registers name strings.
8842 4. Fixed "signed / unsigned compare" compiler warnings.
8843 5. The PIC port manages its own allocation of the general purpose
8844 registers, but makes no attempt to reuse them. As a result when
8845 compiling it soon runs out of general purpose registers. Some
8846 additional code was added to the files pcode.c and device.c to walk
8847 through the function call tree and rename the registers so that they
8857 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8858 genPlus() & genMinus() when the result is the same as left or right

8864 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8866 Made bitfield a distinct type from bit so that bitfields
8867 convert as per ANSI C and bits retain their traditional
8868 boolean style behaviour. Implemented bitfield support in
8876 * src/ds390/gen.c: bit v bitfield split
8877 * src/z80/gen.c: New support for bitfields
8878 * support/regression/tests/bitfields.c: reenabled z80,
8881 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8883 Rules 246.x, 247.x relate to bitfields, the others speed up
8884 access to xdata mapped I/O devices.
8886 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8888 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8890 Cleaned up genPackBits and genUnpackBits and added two helper
8891 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8892 for literal assignments in genPackBits (thanks to Frieder for
8898 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8900 Fixed bug #748310 (pointer to function type mishandled when the
8901 function name is omitted). Also fixed a SIGSEGV when a function
8902 attribute (reentrant, etc) is used on a non-function or on a
8903 function but misplaced before the parameter list.
8905 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8907 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8908 * support/Util/SDCCerr.h,
8909 * support/Util/SDCCerr.c: Added func attr misuse error msg

8930 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8932 Made the constant following the "interrupt" keyword optional. If
8933 omitted, the function will not automatically be given an entry
8934 in the interrupt vector table (similar to #pragma NOIV, but
8935 less syntacticly kludgy). The interrupt number is also now
8936 range checked. Also fixed a bug in the high order bit example

8950 * src/SDCCicode.c (operandOperation): rewritten some ops
8951 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8952 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8954 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8955 be re-activated by defining REDUCE_LITERALS)
8956 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8957 unsigned, but are signed by default
8958 * src/SDCCval.c (constVal): rearranged
8959 * src/SDCCval.c (valMod): preliminary fix
8960 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9466 added if/endif conditional macros to remove options help
9467 messages from optionsTable when a port is not configured, added
9468 support for the PIc16 port in the ports table, when executing
9469 the compiler with no port specified on command line, a default
9470 port is selected with the new macro DEFAULT_PORT which is
9471 defined in port.h, in setDefaultOptions() linkOptions is removed
9472 from initialization assignment, since now it is a set,
9473 parseCmdLine uses setParseWithComma for linkOptions, in
9474 linkEdit() linkOptions are accessed with new function indexSet()
9475 which returns the i'th item of a set variable. See SDCCset.c, in
9476 linkEdit() when calling buildCmdLine(), added linkOptions as
9477 last argument. Now users can pass arguments to gplink via the
9478 -Wl option, main() uses pic16glue() to glue up pic16 programs

9491 * src/pic16/main.c: __config directives are commented out to stop
9492 gpasm complaining and test the linkage with gplink, _linkCmd and
9493 _asmCmd changed to be more gplink and gpasm friendly
9494 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9495 produced an error when parsed, peep rule 12 is added to utilize
9496 movff, but it is commented out since the pCode does not support
9497 yet a command with 2 address arguments
9499 2003-05-18 <johan AT balder>
9501 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9520 Fixed so you can set breakpoints prior to run, run does not stop
9521 on entry now. Add tbreak. Other enhancements and fixes for use
9524 2003-05-12 Borut Razem <borut.razem AT siol.net>
9526 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9528 2003-05-11 Borut Razem <borut.razem AT siol.net>
9530 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10549 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10550 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10556 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10557 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10559 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10560 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10562 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10564 * in \sdcc\as\mcs51\ changed these files in order to create an
10565 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10566 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10567 following files to include the previous two files: aslink.dsp,
10568 Makefile.aslink, Makefile.bcc, and Makefile.in.
10570 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10571 .adb instead of .cdb
10573 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10575 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10576 value from option --iram-size.
10578 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10580 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10583 2002-09-18 <wiml AT hhhh.org>
10585 * SDCClrange.h: exposed setFromRange() and setToRange()
10586 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10587 packRegsForAccUse() (bug 542397)
10588 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10589 multiple times and emitting the fetch operations more than once
10590 added aopGetUsesAcc() function to allow binary operators to
10591 fetch their operands in the correct order; made genMinus() emit
10592 compact code for X = LITERAL - Y
10594 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10595 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10596 sprintf() in line 1267.
10598 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10599 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10602 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10603 Changes to aslink (All the changes are marked with 'JCF'):
10605 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10608 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10609 area BSEG. Also moves, if possible, the DATA area down into the internal
10610 ram so more space is available.
10612 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10615 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10616 not bytes. Function summary() which creates a memory usage summary
10617 file with extension .mem. Reports of overlaping stack and small stack
10618 size. If the space for the stack is less than 16 bytes aslink trows a
10621 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10622 the 8051. Option 'y' for memory summary output file.
10624 Changes to sdcc (All the changes are marked with 'JCF'):
10626 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10628 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10629 overlaying area for it (uses RegBankUsed[4]).
10631 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10632 bank zero as used by default. By default aslink locates the stack
10633 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10634 the creation of the .mem file. Delegates the allocation of data area
10635 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10636 the begining of the stack area to aslink.
10638 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10639 glue() in SDCCglue.c creates an area for it.
10641 2002-09-03 Borut Razem <borut.razem AT siol.net>
10642 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10643 sdcc/src/pic/glue.c:
10644 introduced atexit() handler for teporay files removal in case of
10645 errors, assertions, ...
10647 2002-08-29 Borut Razem <borut.razem AT siol.net>
10648 * sdcc/support/cpp2/auto-host_vc_in.h:
10649 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10650 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10651 Maybe there is a similar problem with BORLANDC? It should be checked!
10653 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10654 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10655 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10656 was not executed, and the compiler (cl) launched a warning:
10657 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10659 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10660 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10662 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10663 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10665 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10666 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10667 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10668 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10669 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10670 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10671 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10672 - added Release configuration in VS projects
10673 - review of compiler an linker options
10674 - VC .exe files are generated in bin_vc directory, not to interfere
10675 with binaries generated from other projects (cygwin, mingw, bcc ...)
10677 * sdcc/src/yacc.dsp: added
10679 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10680 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10681 and insert the version number definitions from .version
10683 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10685 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10686 added - genarate auto-host.h using auto-host_vc_in.h as template
10689 removed from CVS, generated automatically
10691 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10692 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10694 2002-08-11 Borut Razem <borut.razem AT siol.net>
10695 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10697 2002-08-10 Borut Razem <borut.razem AT siol.net>
10698 * src/SDCCmain.c (main):
10699 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10700 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10701 The consequence was that some temporary files were not removed.
10704 unification of code in functions tempfilename() and tempfile():
10705 function tempnam() is defined in Visual Studio 6.0 and .NET
10707 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10709 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10710 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10711 - removed compiler command line option /WX: Treats all warnings as errors
10712 - update a list of source files, included into the project
10714 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10715 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10716 changed project type to Generic Project so that can be correcly converted to VS.NET project
10718 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10720 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10722 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10724 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10725 added return 0 statements after assert() to make compiler happy
10727 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10728 added newline in the def file to keep MSC compiler satisfied
10730 * sdcc/src/z80/gen.c:
10731 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10732 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10733 - solved MSC error in function aopDump()
10735 * sdcc_vc.h: define PREFIX as "\\sdcc"
10737 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10738 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10740 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10741 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10742 - Rewrote the register banking algorithm.
10743 - Added pCode live-range analysis to registers (for now, only non-used and
10744 singly-used registers optimized away)
10746 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10748 * 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.

10771 * src/z80/main.c: Added force callee saves for jaune.
10773 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10775 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10777 2002-03-28 Johan Knol <johan AT balder>
10779 * src/SDCCval.c: fixed bug #532436
10781 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10783 Added "char *Processor" field to the port structure.
10786 Added -p option. Allows port dependent processor to be specified.
10789 Initialized the new field char *Processor field to NULL in all ports
10792 Compiler generated registers for interrupt context saving
10793 were not getting allocated.
10795 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10798 Fixed left shift. Will promote the left side of a left shift
10799 if a) left shifting more than size of operand or b) when assigned
10800 to something size > size of left side
10802 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10804 tons of changes. Register allocation has been
10805 rewritten. Added customization for the various PICs. Flow
10806 analysis is restructured. ...
10808 * src/pic/device.h:
10811 * src/pic/device.c:
10812 Added. device.c is a PIC port hack to accomodate variations
10815 2002-03-13 Michael Hope <michaelh AT vroom>
10817 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10819 2002-03-04 johanknol <johanknol AT manik>
10821 * /src/SDCCval.c: fixed
10823 const unsigned char arr[][2] = { { 0, 1 } };
10824 t18.c:1: error: Initializer element is not constant
10826 2002-03-04 bela <bela AT manik>
10828 * /device/include/mcs51reg.h:
10829 ds89c420 register definition update
