3484 * install-sh: fix bug #1204398 by setting umask 0022
3485 * device/lib/Makefile: separate build of z80 and gbz80 lib
3487 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3489 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3490 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3492 One basic decision: e.g. src/clean.mk includes further files. In order
3493 to make this work there are two solutions:
3494 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3495 run configure on them. This way they can use
3496 'include $(srcdir)/port-clean.mk'
3497 - always include clean.mk by the Makefile at the same level. To avoid
3498 that `make clean` tries to include and build Makefile.dep the
3499 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3500 implemented, because now even `make uninstall` doesn't create
3501 Makefile.in. clean.mk could be eliminated by pasting it in
3504 * debugger/mcs51/Makefile.in: build own objects from library sources
3505 (SLIB, SDCC) in current directory
3507 * configure, configure.in: renamed --disable-device-lib-build in
3508 --disable-device-lib; added --enable-doc, the required tools are
3509 searched by configure; added result message; the toolchain for the
3510 belonging ports are now only built, if the port is enabled.
3512 * support/regression/*: all output is written in directory gen, because
3513 the fwk and ports directories don't livet in the build tree using vpath
3515 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3516 --disable-device-lib, added --enable-doc, added section VPATH
3518 * sim/ucsim/configure.in,
3519 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3520 z80 are enabled by default
3522 2006-04-24 Raphael Neider <rneider AT web.de>
3524 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3525 to config word, "pic14_"-prefixed some extern functions
3526 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3527 config word has been found
3528 * src/pic/device.h: added prototypes
3529 * src/pic/pcode.c: added "pic14_"-prefix where needed

3838 call to allocReg, not by manually allocating a new one,
3839 (pic16_assignRegisters): now before going through the register
3840 allocating functions mark all registers as free. This eliminates some
3841 side effects resulting from peephole parser done earlier in the backbone

3909 _main (this should take care the --main-return command line option in
3911 (genOr): removed some legacy pic-port instructions,
3912 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3913 performing operations with SFR's causes data to be written more than
3914 once to each SFR. Perhaps SFRs should be handled in special cases...
3915 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3917 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3918 into account for stack starting position,
3919 (struct OPTIONS pic16_optionsTable): added command line argument
3920 --extended or -y for Extended Instruction Support,
3921 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3922 (deassignLRs): *** perhaps the most important change, old 'for' code
3923 (commented out for reference), didn't account for some registers which
3924 were left marked 'not free' after a pointer operation. The change
3925 reduces register usage a lot in some cases

6198 * src/SDCCglobal.h (struct options),
6200 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6201 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6202 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6203 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6204 always available in leading double underscore form. The C99 support is
6205 mostly missing, but it's a start.
6206 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6207 reserved identifier "__data".

6285 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6287 * device/lib/printf_large.c: removed inline assembly for portability and
6288 readability. Use printf_fast if speed or size are more important.
6289 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6290 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6292 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6294 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6295 prevent compiler warning
6297 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6299 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6300 moved to level 0 and declared as static. Also they are explicit
6301 placed in access bank. This was necessery because some times they
6302 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6303 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6304 optimizations. Currently only compare to unsigned char is implemented,
6305 * src/pic16/gen.c: added fReturnIdx array,
6306 * (struct resolvedIfx) is moved to gen.h and made public,
6307 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6308 * (aopForSym): added an optimization to directly store in stack of
6309 the operand of a SEND iCode,
6310 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6311 but as registers instead (AOP_REG) using the fReturnIdx array,
6312 * (pic16_freeAsmop): remove the freed register from the
6313 _G.sregsAlloc field,
6314 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6315 a compare of 'WREG',
6316 * (pic16_popGetTempRegCond): changed function prototype, now
6317 function takes also a bitVector argument v which holds the current
6318 set of registers that are allocated for stack access by aopForSym,
6319 registers allocated in aopForSym for accessing stack symbols are not
6320 any more part of the functions usedRegs field,
6321 * (genCall): some times aopOp is called for a stack variable to be
6322 send, aopForSym might perform the push, if this is true make sure
6323 that genCall doesn't push the variable twice by testing _G.resDirect,
6324 * (genFunction): changed testing for unspecified interrupt number
6325 from 256 to INTNO_UNSPEC,
6326 * modified selection scheme of frame pointer generation. Previously
6327 if function did use local registers a frame pointer was generated,
6328 now a frame pointer is generated only if function has arguments
6329 (that need PLUSW2 register access), or has stack arguments, or the
6330 compiler is not instructed to omit the frame pointer,
6331 * (genEndFunction): before restoring local registers that were saved
6332 in the function preamble, also restore the registers that *might*
6333 have been allocated for stack access,
6334 * (genRet): removed some old comments,
6335 * (genCmp, the active (RN's) version): added a call to the
6336 pic16_genCmp_special function to perform the compare with a more
6337 robust and optimized way,
6338 * (genInline): a feature has been added in inline code generation,
6339 which allows a wildcard variable substitution when writing inline
6340 assembly. Code is incomplete and experimental therefore undocumented,
6341 * (genCast): changed order of aopOp for result and right to allow
6342 aopForSym to directly load the result if possible,
6343 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6344 perform an optimized compare on some selected special occasions,
6345 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6346 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6347 generate an IVT any more,
6348 * src/pic16/main.c (pic16_optionsTable): added command line option
6350 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6351 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6353 * src/pic16/NOTES: Raphael Neider added in list of active developers
6354 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6355 jumptable_end to prevent bug #,
6356 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6357 inCond and outCond fields,
6358 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6359 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6360 turn off register spilling,
6361 * (packRegsForOneUse): synced with other ports' versions although it
6362 is not used currently,
6363 * (pic16_packRegisters): added an optimization while reading
6364 structure bitfields, some registers may be saved (malloc code is
6365 decreased by 80 bytes)
6367 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6369 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6370 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6371 this can be optimized more?
6373 2005-03-10 Raphael Neider <rneider AT web.de>
6375 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6376 genNearPointerGet): (hopefully) fixed access to bitfields via
6377 pointers (p->bitN = x; and x = p->bitN; failed)
6379 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6422 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
6423 to keep the correct label reference count when adding/removing references
6424 to labels. A peephole file using this is appended to patch #1144962.
6426 2005-02-14 Raphael Neider <rneider AT web.de>

7011 Adding support for replacing ljmps with sjmps in jumptables
7012 generated for switch statements. For now you need to set the
7013 environment variable SDCC_SJMP_JUMPTABLE to enable this.
7014 Now 4 algorithms for mcs51 jumptable generation are used:
7015 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
7016 addresses loaded pc-relative for up to 112 cases and stack-pushing
7017 target addresses loaded with offset from dptr for up to 256 cases.

7047 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
7049 * added libc directory. The current version of LibC contains string
7050 functions, ctype functions and macros and some functions of the
7051 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
7052 be extensively tested in the future. Standard disclaimer here.
7053 Library is not automatically build yet. But one can build it by
7054 invoking 'make' inside the libc directory.

7065 * (pic16_storeForReturn): optimized return of 0,
7066 * (genCmp): experimental code for new genCmp which uses PIC18's
7067 special compare&skip instructions. Initial tests fail some times
7068 with variables grater than 1 byte in size, so new code is disabled,
7069 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
7071 * (genCast): began a fix to optimize the casting of a bit to another
7072 bit, now assigning a bitfield to another bitfield will fail, sorry,

7081 and 1 for banking instruction,
7082 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
7083 caused stop processing pCodes after a inline assembly block,
7084 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

7086 registers when it shouldn't,
7087 * src/pic16/ralloc.c (allocReg): add preliminary support for
7088 supporting a limited set of temporary registers,
7090 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10009 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
10011 * src/SDCCast.c: added an additional type flow in decorateType() of
10012 opposite direction, see feature request #860006; it's enabled at runtime
10013 by setting the environment variable SDCC_NEWTYPEFLOW
10014 * src/SDCCast.h: changed prototype of decorateType()
10015 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
10016 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

10047 * src/pic/ralloc.h: applied patch from Slade Rich;
10048 added support for multiple code pages and multiple RAM banks on the
10049 PIC 14 port. The ASM files now no longer simply assume all the
10050 code / RAM are in the same page / bank. This means the linker can
10051 safely allocate code/RAM of separate ASM files to different pages/banks.
10052 * doc/sdccman.lyx: added Slade's tips

10095 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
10097 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
10098 loaded with the linker search paths (-L arguments) and the libraries
10099 to be linked with the current source (-l arguments). Changes
10100 currently will affect only the pic16 port.
10101 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
10102 include path the port specific paths and port specific libraries,
10103 * gplink command now contains the $3 argument,
10104 * src/pic16/device.h,
10105 * src/pic16/device.c,: structure PIC_device is made public and
10106 renamed to PIC16_device, the same for variable Pics which is renamed
10107 to Pics16. Updated all references to them.

10119 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
10121 Documenting changes from previous commits.
10122 * configure.in (version 1.56),
10123 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
10124 when generating output files to configure the pic16 library,
10125 but now I've commented it out, since gputils aren't installed in the
10126 SF compile farm, so library won't compile
10128 * device/lib/Makefile.in (version 1.56): initially I've added in
10129 target 'all' the prerequestive 'model-pic16' so it compiled the
10130 pic16 library, but now I've commented it out for the same reasons
10132 * added targets 'model-pic16' and 'objects-pic16' to compile the
10134 * added target 'port-specific-objects-pic16' to handle the
10135 generated libraries and copy them into the build/ directory
10136 * added target 'clean-intermediate-pic16' to clean intermediate
10137 files into pic16 directory
10138 * in target 'installdirs' added line to create directory pic16 in
10139 the installation path
10141 * device/include/Makefile.in (version 1.11): in target 'install'
10142 added lines to copy all header files to installation path,
10143 * in target 'installdirs' added line create directory for pic16
10144 headers in the installation path

10159 * src/z80/main.c (_parseOptions): fixed the portmode= command line
10160 option so that it actually works. Made it specific to the z80, since
10161 the gbz80 doesn't have these kinds of I/O ports.
10163 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10196 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10198 Added portion of GNU PIC Library under the directory
10199 device/include/pic16 and device/lib/pic16. These files
10200 contain the declarations of SFRs for the PIC18Fxx2 devices.
10201 The directory is initialized via configure from toplevel.
10203 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
10205 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

10437 genFunction,genEndFunction: setup stack frame for the
10438 generated function,
10439 genAddrOf: will be changed according to bug 863624
10441 * added files genutils.c and genutils.h which contain gen*
10442 debugged and optimised functions extracted from gen.c
10444 * glue.c: added variable 'externs' which holds extern symbols,
10445 pic16emitRegularMap: is modified to properly handle relocatable
10446 symbols under the new scheme,
10447 pic16createInterruptVect: is modified
10448 pic16printPublics: is modified to emit 'global' assembler directives,
10449 added pic16_printExterns to print extern symbols,
10450 pic16glue: initializes stack/frame pointer in the beginning of
10451 the assembly output. Temporary hack, will be corrected later,
10452 because gplink yet does not support stack and SDCC does not
10453 yet support a type of crt0.o object to create the final binary.
10455 * Removed many lines that contain 8051 legacy code.
10456 * The code is finally placed under a 'code' directive.
10457 * Added port specific options.
10459 * _process_pragma: simplified since now we do not need *special*
10460 include file to define SFR registers. But a separate header
10461 will be needed. This will be developed later.
10462 * _pic16_parseOptions: added, parses port specific options:
10463 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10464 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10465 --preplace-udata-with=
10467 * _pic16_setDefaultOptions: modified to initialize section names,
10468 but hack is temporarly out of order since it needs improvement.
10469 * _pic16_genAssemblerPreamble: configuration words are emitted by
10470 their address instead of their name. This part is incomplete and
10471 supports only the 18Fxx2 devices. Other devices will emit an error
10472 during assembly since they do not contain the same set of config
10474 * _pic16_genIVT: is modified,
10476 * pcode.c: added definitions for some hardware registers that are needed
10478 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10479 All PCI entries are updated. Now LFSR is supported.
10480 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10481 * added pic16_newpCodeOpLit2 to support instructions with
10482 two literal arguments
10483 * pic16_pCode2str: corrected code that emits assembler instructions
10484 with two literal operands and those that have an access bit modifier
10485 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10486 this fixes a bug which caused some labels to be lost, when an
10487 assembler directive was added, i.e. banksel,
10488 * pic16_FixRegisterBanking: improved logic that causes the insertion
10490 * InlineFunction: functions that are called once, are not any more
10491 inlined. This can be a port option in the future,
10493 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10495 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10496 hold the corresponding uninitialized symbols,
10497 * pic16_allocProcessorRegister: registers have explicit marked the
10499 * pic16_allocInternalRegister: registers are explicit marked as
10501 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10502 processing list, so bit registers were lost,
10505 * ralloc.h: added field 'accessBank' and original symbol operand
10506 in register definition,
10507 * removed the field isMapped from register definition,
10509 ** Several functions have been removed from various sources:
10510 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10511 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10512 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10513 pic16_assignRelocatableRegisters
10515 ** others have been introduced:
10516 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10517 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10519 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10521 * support/scripts/inc2h.pl: changed definition of BIT_AT
10522 to emit 'sbit at' instead of 'bit at'. This was a request.
10524 PIC16 port related preliminary changes:
10525 * gen.c: prefixed function popRegFromString with
10526 pic16_ and all references to it corrected
10527 * pcode.c: all pic16_pc_* hardware registers prefixed
10528 with underscore (_),
10529 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10530 * ralloc.c: newReg(): when register is REG_SFR then
10531 set address to rIdx,
10532 pic16_allocProcessorRegister(): marks register wasUsed=0
10533 pic16_writeUsedRegs(): added a call to assign processor
10534 registers via pic16_assignFixedRegisters
10536 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10538 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10539 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10540 variables in unused register banks. Also the SSEG is placed
10541 wherever there is enough space for it, and IDATA can be anywhere
10542 in internal RAM. For now compile using -Wl-Y[stack_size].
10543 The mem file is different for this option as well, since it
10544 makes no sense of talking about DSEG lenght.
10546 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10548 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10549 in certain cases, e.g. when ROM assignment, patch provided
10550 from Albert den Haan.

10695 * src/mcs51/peephole.def,
10696 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
10697 (allows non-interrupt and interrupt code to safely compete for a resource
10698 without the non-interrupt code having to disable interrupts)
10700 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10702 * src/SDCCicode.c (geniCodeAdd),
10703 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
10704 with valFromType if type might be a pointer and host is big endian).
10705 * src/SDCCast.c (decorateType): unary plus compatible with all arithmetic
10706 types, not just integer types.
10707 * src/SDCCsymt.c (addSymChain): clarified error message when symbol is
10708 multiply defined with mismatching "at" address.

10791 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10793 * src/SDCCast.c (decorateType): disabled a transformation I added in
10794 revision 1.188 (access to fields of a structure at an absolute address);
10795 it breaks with bitfields, extern declarations, and gcse analysis.
10796 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10797 could be assigned through a pointer, so don't complain.
10798 * src/SDCCast.c (astErrors),
10800 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

11380 genCodePointerGet, genGenPointerGet, genFarPointerSet,
11381 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
11382 (ralloc doesn't intentionally do this now, but perhaps later)
11383 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
11384 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

11396 2003-09-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11398 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
11399 of const struct should be treated as if const themselves)
11401 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
11403 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

11418 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
11419 and restore of EA so that stack offsets to parameters are
11420 correct when using both critical and reentrant/stack-auto.
11421 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
11422 size (can be triggered in error if sloc is shared between
11423 different sized objects)
11424 * device/include/float.h: fixed macros to explicitly use
11425 unsigned long where needed
11427 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

11435 * src/SDCCsymt.c (sclsFromPtr),
11437 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
11438 support for standard C idiom of memory mapped variables; for
11439 example, *((xdata int*)0x1234) = 1 is now internally equivalent
11440 to xdata int at 0x1234 tempvar = 1.
11441 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
11442 provided by Akiya ISHIDA

11458 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11460 Fixed bug #621531 (const & volatile confusion in the type chain).
11461 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
11462 refer to the const or volatile state of the pointer itself.

11527 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
11528 pcoderegs.h, ralloc.c, ralloc.h
11529 * main.c: added top header and GPL license notice

11532 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11534 * device/lib/_mullong.c: replaced int by short for gcc
11536 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11538 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11539 and JUMPTABLE iCodes properly now (worked by accident before)
11540 * src/mcs51/gen.c (leftRightUseAcc),
11541 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11542 iCode properly now. Use getSize instead of nRegs since a & b
11543 aren't part of the nRegs tally.
11545 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11547 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11556 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
11557 copied from genNearPointerSet()
11558 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11559 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11560 If they pop r0/r1 they must be called in the opposite order than aopOp().
11561 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11562 (resp. --stack-auto), prepared for --xstack
11564 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11566 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11568 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11570 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
11571 these ports have their own __sdcc_external_start()
11573 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11575 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11576 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11577 type for bits was changed. It resulted in bit variables becoming
11578 global, which is not permitted in PIC 14 assembly output.
11580 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11582 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11584 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11586 Z80 and MCS51 linkers complaint if a public symbol is defined
11587 in more than one library module:

11593 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11595 A few small changes that speed up the peephole optimizer.
11599 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11601 Try to make the peephole optimizer smarter by maintaining
11602 an association between the assembly source code and the
11603 iCodes that originated them. Put this information to use
11604 with a new peephole rule condition "notVolatile" so that
11605 the rules can be aggressive yet still safe.
11610 * src/mcs51/peeph.def
11612 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11616 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11617 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11618 if the left or right operand symbols have the accuse flag set.
11620 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11622 Changed the type of the result of the ! (NOT) operator to char;
11623 previously it returned the same type as the source. This allows
11624 us to eliminate all the genFloatNot functions (all of its target
11625 implementations were very buggy) since !float can use the same
11628 * src/SDCCicode.c (ast2iCode): ! returns char
11629 * src/mcs51/gen.c (genNot, genNotFloat),
11630 * src/ds390/gen.c (genNot, genNotFloat),
11631 * src/z80/gen.c (genNot, genNotFloat),
11632 * src/pic/gen.c (genNot, genNotFloat),
11633 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11635 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11637 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11638 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11639 during interrupts. Ensure WSAVE is located at a shared bank address.
11640 2. Fixed page selection in some places
11641 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11642 the registers name strings.
11643 4. Fixed "signed / unsigned compare" compiler warnings.
11644 5. The PIC port manages its own allocation of the general purpose
11645 registers, but makes no attempt to reuse them. As a result when
11646 compiling it soon runs out of general purpose registers. Some
11647 additional code was added to the files pcode.c and device.c to walk
11648 through the function call tree and rename the registers so that they
11658 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11659 genPlus() & genMinus() when the result is the same as left or right
11661 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11663 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11665 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11667 Made bitfield a distinct type from bit so that bitfields
11668 convert as per ANSI C and bits retain their traditional
11669 boolean style behaviour. Implemented bitfield support in
11677 * src/ds390/gen.c: bit v bitfield split
11678 * src/z80/gen.c: New support for bitfields
11679 * support/regression/tests/bitfields.c: reenabled z80,
11682 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11684 Rules 246.x, 247.x relate to bitfields, the others speed up
11685 access to xdata mapped I/O devices.
11687 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11689 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11691 Cleaned up genPackBits and genUnpackBits and added two helper
11692 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11693 for literal assignments in genPackBits (thanks to Frieder for
11699 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11701 Fixed bug #748310 (pointer to function type mishandled when the
11702 function name is omitted). Also fixed a SIGSEGV when a function
11703 attribute (reentrant, etc) is used on a non-function or on a
11704 function but misplaced before the parameter list.
11706 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11708 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11709 * support/Util/SDCCerr.h,
11710 * support/Util/SDCCerr.c: Added func attr misuse error msg
11712 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11714 Fixed bug #787649 by anonymous
11715 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11716 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11718 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11720 Fixed numerous bitfield problems.
11722 * src/SDCC.y: More bitfield related error checking
11724 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
11725 * support/Util/SDCCerr.h,
11726 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
11727 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11728 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
11729 * support/regression/tests/bitfields.c: tests added
11731 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11733 Made the constant following the "interrupt" keyword optional. If
11734 omitted, the function will not automatically be given an entry
11735 in the interrupt vector table (similar to #pragma NOIV, but
11736 less syntacticly kludgy). The interrupt number is also now
11737 range checked. Also fixed a bug in the high order bit example

11745 * support/Util/SDCCerr.h
11748 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11750 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
11751 * src/SDCCicode.c (operandOperation): rewritten some ops
11752 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11753 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11755 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11756 be re-activated by defining REDUCE_LITERALS)
11757 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11758 unsigned, but are signed by default
11759 * src/SDCCval.c (constVal): rearranged
11760 * src/SDCCval.c (valMod): preliminary fix
11761 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11799 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
11801 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11802 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11803 constants are unsigned; added recognition of "u" flag for unsigned
11804 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11805 * src/SDCCval.c (valDiv, valMod): fixed signdness
11806 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11807 signedness of modulo, left and right shift

11862 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
11864 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
11865 there, while the mantissa of a double is "only" 53 bits wide.
11867 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

12268 messages from optionsTable when a port is not configured, added
12269 support for the PIc16 port in the ports table, when executing
12270 the compiler with no port specified on command line, a default
12271 port is selected with the new macro DEFAULT_PORT which is
12272 defined in port.h, in setDefaultOptions() linkOptions is removed
12273 from initialization assignment, since now it is a set,
12274 parseCmdLine uses setParseWithComma for linkOptions, in
12275 linkEdit() linkOptions are accessed with new function indexSet()
12276 which returns the i'th item of a set variable. See SDCCset.c, in
12277 linkEdit() when calling buildCmdLine(), added linkOptions as
12278 last argument. Now users can pass arguments to gplink via the
12279 -Wl option, main() uses pic16glue() to glue up pic16 programs

12293 gpasm complaining and test the linkage with gplink, _linkCmd and
12294 _asmCmd changed to be more gplink and gpasm friendly
12295 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12296 produced an error when parsed, peep rule 12 is added to utilize
12297 movff, but it is commented out since the pCode does not support
12298 yet a command with 2 address arguments

13360 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
13361 * src/mcs51/main.c: removed {bindir}{sep} from aslink
13363 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13365 * in /sdcc/as/mcs51/ changed these files in order to create an
13366 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
13367 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
13368 following files to include the previous two files: aslink.dsp,
13369 Makefile.aslink, Makefile.bcc, and Makefile.in.
13371 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
13372 .adb instead of .cdb
13374 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13376 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
13377 value from option --iram-size.
13379 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13381 * /sdcc/as/mcs51/lklist.c: added boundary check before using
13384 2002-09-18 <wiml AT hhhh.org>
13386 * SDCClrange.h: exposed setFromRange() and setToRange()
13387 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
13388 packRegsForAccUse() (bug 542397)
13389 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
13390 multiple times and emitting the fetch operations more than once
13391 added aopGetUsesAcc() function to allow binary operators to
13392 fetch their operands in the correct order; made genMinus() emit
13393 compact code for X = LITERAL - Y
13395 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13396 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
13397 sprintf() in line 1267.
13399 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13400 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
13403 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
13404 Changes to aslink (All the changes are marked with 'JCF'):
13406 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
13409 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
13410 area BSEG. Also moves, if possible, the DATA area down into the internal
13411 ram so more space is available.
13413 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
13416 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
13417 not bytes. Function summary() which creates a memory usage summary
13418 file with extension .mem. Reports of overlaping stack and small stack
13419 size. If the space for the stack is less than 16 bytes aslink trows a
13422 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
13423 the 8051. Option 'y' for memory summary output file.
13425 Changes to sdcc (All the changes are marked with 'JCF'):
13427 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13429 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13430 overlaying area for it (uses RegBankUsed[4]).
13432 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13433 bank zero as used by default. By default aslink locates the stack
13434 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13435 the creation of the .mem file. Delegates the allocation of data area
13436 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13437 the begining of the stack area to aslink.
13439 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13440 glue() in SDCCglue.c creates an area for it.
13442 2002-09-03 Borut Razem <borut.razem AT siol.net>
13443 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13444 sdcc/src/pic/glue.c:
13445 introduced atexit() handler for teporay files removal in case of
13446 errors, assertions, ...
13448 2002-08-29 Borut Razem <borut.razem AT siol.net>
13449 * sdcc/support/cpp2/auto-host_vc_in.h:
13450 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13451 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13452 Maybe there is a similar problem with BORLANDC? It should be checked!
13454 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13455 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13456 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13457 was not executed, and the compiler (cl) launched a warning:
13458 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13460 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13461 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13463 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13464 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13466 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13467 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13468 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13469 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13470 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13471 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13472 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13473 - added Release configuration in VS projects
13474 - review of compiler an linker options
13475 - VC .exe files are generated in bin_vc directory, not to interfere
13476 with binaries generated from other projects (cygwin, mingw, bcc ...)
13478 * sdcc/src/yacc.dsp: added
13480 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13481 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13482 and insert the version number definitions from .version
13484 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13486 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13487 added - genarate auto-host.h using auto-host_vc_in.h as template
13490 removed from CVS, generated automatically
13492 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13493 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13495 2002-08-11 Borut Razem <borut.razem AT siol.net>
13496 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13498 2002-08-10 Borut Razem <borut.razem AT siol.net>
13499 * src/SDCCmain.c (main):
13500 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13501 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13502 The consequence was that some temporary files were not removed.
13505 unification of code in functions tempfilename() and tempfile():
13506 function tempnam() is defined in Visual Studio 6.0 and .NET
13508 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13510 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13511 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13512 - removed compiler command line option /WX: Treats all warnings as errors
13513 - update a list of source files, included into the project
13515 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13516 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13517 changed project type to Generic Project so that can be correcly converted to VS.NET project
13519 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13521 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13523 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13525 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13526 added return 0 statements after assert() to make compiler happy
13528 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13529 added newline in the def file to keep MSC compiler satisfied
13531 * sdcc/src/z80/gen.c:
13532 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13533 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13534 - solved MSC error in function aopDump()
13536 * sdcc_vc.h: define PREFIX as "\\sdcc"
13538 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13539 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13542 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13543 - Rewrote the register banking algorithm.
13544 - Added pCode live-range analysis to registers (for now, only non-used and
13545 singly-used registers optimized away)
13547 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13549 * 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.

13576 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13578 2002-03-28 Johan Knol <johan AT balder>
13580 * src/SDCCval.c: fixed bug #532436
13582 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13584 Added "char *Processor" field to the port structure.
13587 Added -p option. Allows port dependent processor to be specified.
13590 Initialized the new field char *Processor field to NULL in all ports
13593 Compiler generated registers for interrupt context saving
13594 were not getting allocated.
13596 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13599 Fixed left shift. Will promote the left side of a left shift
13600 if a) left shifting more than size of operand or b) when assigned
13601 to something size > size of left side
13603 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13605 tons of changes. Register allocation has been
13606 rewritten. Added customization for the various PICs. Flow
13607 analysis is restructured. ...
13609 * src/pic/device.h:
13612 * src/pic/device.c:
13613 Added. device.c is a PIC port hack to accomodate variations
13616 2002-03-13 Michael Hope <michaelh AT vroom>
13618 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13620 2002-03-04 johanknol <johanknol AT manik>
13622 * /src/SDCCval.c: fixed
13624 const unsigned char arr[][2] = { { 0, 1 } };
13625 t18.c:1: error: Initializer element is not constant
13627 2002-03-04 bela <bela AT manik>

13714 Previous fix was not good. basic blocks that have "break" or "return" are
13715 not really partof a loop , but live ranges used in these blocks should
