1696 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1698 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1699 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1701 One basic decision: e.g. src/clean.mk includes further files. In order
1702 to make this work there are two solutions:
1703 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1704 run configure on them. This way they can use
1705 'include $(srcdir)/port-clean.mk'
1706 - always include clean.mk by the Makefile at the same level. To avoid
1707 that `make clean` tries to include and build Makefile.dep the
1708 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1709 implemented, because now even `make uninstall` doesn't create
1710 Makefile.in. clean.mk could be eliminated by pasting it in
1713 * debugger/mcs51/Makefile.in: build own objects from library sources
1714 (SLIB, SDCC) in current directory
1716 * configure, configure.in: renamed --disable-device-lib-build in
1717 --disable-device-lib; added --enable-doc, the required tools are
1718 searched by configure; added result message; the toolchain for the
1719 belonging ports are now only built, if the port is enabled.
1721 * support/regression/*: all output is written in directory gen, because
1722 the fwk and ports directories don't livet in the build tree using vpath
1724 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1725 --disable-device-lib, added --enable-doc, added section VPATH
1727 * sim/ucsim/configure.in,
1728 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1729 z80 are enabled by default
1731 2006-04-24 Raphael Neider <rneider AT web.de>
1733 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1734 to config word, "pic14_"-prefixed some extern functions
1735 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1736 config word has been found
1737 * src/pic/device.h: added prototypes
1738 * src/pic/pcode.c: added "pic14_"-prefix where needed
1739 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1741 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1743 (pic14emitRegularMap): ignore config words,
1744 (pic14createInterruptVect): moved generating __config directives away
1745 (picglue): have __config directives emitted
1747 2006-04-24 Borut Razem <borut.razem AT siol.net>
1749 * doc/Makefile: sync with nightly build makefile
1751 2006-04-24 Raphael Neider <rneider AT web.de>
1753 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1754 registers that have not been assigned proper liveranges,
1755 fixes #1469504 and #1474602,
1756 (pCodeRegOptimizeRegUsage): fixed typo in comment
1758 2006-04-24 Borut Razem <borut.razem AT siol.net>
1760 * device/examples/main8051.c: deleted - it was removed from CVS
1761 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1762 after the transition to Subversion
1763 * src/SDCCalloc.h: deleted - it was removed from CVS
1764 3.feb.2001 and after that modified 18.feb.2001, so it reappered
1765 after the transition to Subversion

2026 * src/.version: increased version number to 2.5.5
2027 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2028 linking is done manually in pic16 port's _linkEdit,
2029 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2030 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2031 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2032 allocate asmop as AOP_ACC,
2033 (aopForRemat): added parameter 'bool result' in function declaration,
2034 (pic16_aopGet): return AOP_ACC when accessing WREG,

2047 call to allocReg, not by manually allocating a new one,
2048 (pic16_assignRegisters): now before going through the register
2049 allocating functions mark all registers as free. This eliminates some
2050 side effects resulting from peephole parser done earlier in the backbone

2112 the number of the local variables used by the specified function, added
2113 'xinst' for initial support for Extended Instruction Support,
2114 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2115 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2116 port->fun_prefix anymore (may change later),
2117 (genFunction, genEndFunction): do not store/restore local registers for
2118 _main (this should take care the --main-return command line option in
2120 (genOr): removed some legacy pic-port instructions,
2121 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2122 performing operations with SFR's causes data to be written more than
2123 once to each SFR. Perhaps SFRs should be handled in special cases...
2124 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2126 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2131 (deassignLRs): *** perhaps the most important change, old 'for' code
2132 (commented out for reference), didn't account for some registers which
2133 were left marked 'not free' after a pointer operation. The change
2134 reduces register usage a lot in some cases

4410 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4411 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4412 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4413 always available in leading double underscore form. The C99 support is
4414 mostly missing, but it's a start.
4415 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4496 * device/lib/printf_large.c: removed inline assembly for portability and
4497 readability. Use printf_fast if speed or size are more important.
4498 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4499 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4501 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4503 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4504 prevent compiler warning
4506 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4508 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4509 moved to level 0 and declared as static. Also they are explicit
4510 placed in access bank. This was necessery because some times they
4511 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4512 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4513 optimizations. Currently only compare to unsigned char is implemented,
4514 * src/pic16/gen.c: added fReturnIdx array,
4515 * (struct resolvedIfx) is moved to gen.h and made public,
4516 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4517 * (aopForSym): added an optimization to directly store in stack of
4518 the operand of a SEND iCode,
4519 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4520 but as registers instead (AOP_REG) using the fReturnIdx array,
4521 * (pic16_freeAsmop): remove the freed register from the
4522 _G.sregsAlloc field,
4523 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4524 a compare of 'WREG',
4525 * (pic16_popGetTempRegCond): changed function prototype, now
4526 function takes also a bitVector argument v which holds the current
4527 set of registers that are allocated for stack access by aopForSym,
4528 registers allocated in aopForSym for accessing stack symbols are not
4529 any more part of the functions usedRegs field,
4530 * (genCall): some times aopOp is called for a stack variable to be
4531 send, aopForSym might perform the push, if this is true make sure
4532 that genCall doesn't push the variable twice by testing _G.resDirect,
4533 * (genFunction): changed testing for unspecified interrupt number
4534 from 256 to INTNO_UNSPEC,
4535 * modified selection scheme of frame pointer generation. Previously
4536 if function did use local registers a frame pointer was generated,
4537 now a frame pointer is generated only if function has arguments
4538 (that need PLUSW2 register access), or has stack arguments, or the
4539 compiler is not instructed to omit the frame pointer,
4540 * (genEndFunction): before restoring local registers that were saved
4541 in the function preamble, also restore the registers that *might*
4542 have been allocated for stack access,
4543 * (genRet): removed some old comments,
4544 * (genCmp, the active (RN's) version): added a call to the
4545 pic16_genCmp_special function to perform the compare with a more
4546 robust and optimized way,
4547 * (genInline): a feature has been added in inline code generation,
4548 which allows a wildcard variable substitution when writing inline
4549 assembly. Code is incomplete and experimental therefore undocumented,
4550 * (genCast): changed order of aopOp for result and right to allow
4551 aopForSym to directly load the result if possible,
4552 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4553 perform an optimized compare on some selected special occasions,
4554 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4555 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4556 generate an IVT any more,
4557 * src/pic16/main.c (pic16_optionsTable): added command line option
4559 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4560 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4562 * src/pic16/NOTES: Raphael Neider added in list of active developers
4563 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4564 jumptable_end to prevent bug #,
4565 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4566 inCond and outCond fields,
4567 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4568 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4569 turn off register spilling,
4570 * (packRegsForOneUse): synced with other ports' versions although it
4571 is not used currently,
4572 * (pic16_packRegisters): added an optimization while reading
4573 structure bitfields, some registers may be saved (malloc code is
4574 decreased by 80 bytes)
4576 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4578 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4579 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4580 this can be optimized more?
4582 2005-03-10 Raphael Neider <rneider AT web.de>
4584 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4585 genNearPointerGet): (hopefully) fixed access to bitfields via
4586 pointers (p->bitN = x; and x = p->bitN; failed)
4588 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5220 Adding support for replacing ljmps with sjmps in jumptables
5221 generated for switch statements. For now you need to set the
5222 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5223 Now 4 algorithms for mcs51 jumptable generation are used:
5224 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5225 addresses loaded pc-relative for up to 112 cases and stack-pushing
5226 target addresses loaded with offset from dptr for up to 256 cases.
5228 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5229 * src/mcs51/main.c: adapted constants for switch table generation

5253 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5254 to call when a stack overflow occurs,
5255 * (malloc.h): added CVS Id tag,
5256 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5258 * added libc directory. The current version of LibC contains string
5259 functions, ctype functions and macros and some functions of the
5260 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5261 be extensively tested in the future. Standard disclaimer here.
5262 Library is not automatically build yet. But one can build it by
5263 invoking 'make' inside the libc directory.
5264 * added ADC library under libio. Preliminary version yet.
5266 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5273 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5274 * (pic16_storeForReturn): optimized return of 0,
5275 * (genCmp): experimental code for new genCmp which uses PIC18's
5276 special compare&skip instructions. Initial tests fail some times
5277 with variables grater than 1 byte in size, so new code is disabled,
5278 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5280 * (genCast): began a fix to optimize the casting of a bit to another
5281 bit, now assigning a bitfield to another bitfield will fail, sorry,
5282 * src/pic16/main.c: disabled the use of lr-support feature,
5283 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5284 * added some function prototypes, added function _debugf prototype,

5286 bits with offset (case PO_GPR_BIT),
5287 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5289 * (isBankInstruction): modified to return 0 for no banking instruction,
5290 and 1 for banking instruction,
5291 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5292 caused stop processing pCodes after a inline assembly block,
5293 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5294 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5295 registers when it shouldn't,
5296 * src/pic16/ralloc.c (allocReg): add preliminary support for
5297 supporting a limited set of temporary registers,
5299 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5301 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5302 genDataPointerSet): ensure assignments always copy in MSB to LSB
5304 (loadRegFromAop): recognize CLRH optimization,
5305 (genFunction): optimize RECEIVE iCodes in reentrant functions
5307 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5309 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8304 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8306 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8307 loaded with the linker search paths (-L arguments) and the libraries
8308 to be linked with the current source (-l arguments). Changes
8309 currently will affect only the pic16 port.
8310 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8311 include path the port specific paths and port specific libraries,
8312 * gplink command now contains the $3 argument,
8313 * src/pic16/device.h,
8314 * src/pic16/device.c,: structure PIC_device is made public and
8315 renamed to PIC16_device, the same for variable Pics which is renamed
8316 to Pics16. Updated all references to them.
8317 * src/pic16/glue.c (pic16glue): corrected bug with code
8318 initialization which bypassed the variable initializations block.

8328 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8330 Documenting changes from previous commits.
8331 * configure.in (version 1.56),
8332 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8333 when generating output files to configure the pic16 library,
8334 but now I've commented it out, since gputils aren't installed in the
8335 SF compile farm, so library won't compile
8337 * device/lib/Makefile.in (version 1.56): initially I've added in
8338 target 'all' the prerequestive 'model-pic16' so it compiled the
8339 pic16 library, but now I've commented it out for the same reasons
8341 * added targets 'model-pic16' and 'objects-pic16' to compile the
8343 * added target 'port-specific-objects-pic16' to handle the
8344 generated libraries and copy them into the build/ directory
8345 * added target 'clean-intermediate-pic16' to clean intermediate
8346 files into pic16 directory
8347 * in target 'installdirs' added line to create directory pic16 in
8348 the installation path
8350 * device/include/Makefile.in (version 1.11): in target 'install'
8351 added lines to copy all header files to installation path,
8352 * in target 'installdirs' added line create directory for pic16
8353 headers in the installation path

8368 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8369 option so that it actually works. Made it specific to the z80, since
8370 the gbz80 doesn't have these kinds of I/O ports.
8372 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8374 * device/include/z180.h,

8387 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8389 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8390 changed interrupt vector table generation to only emit declared vectors.
8391 * device/include/Makefile.in: added missing backslash
8392 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

8396 Mainly changes to support compilation of the device libraries
8397 * src/pic16/device.c: stack is allocated via symbol and not
8398 via literal number. The symbol is placed in the corresponding
8399 position of the data ram
8400 * (pic16_dump_section): relocatable and absolute uninitialized
8401 data are now emitted in sorted order to reduce section naming,
8402 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8403 weren't marked as being in the access bank,
8405 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8407 Added portion of GNU PIC Library under the directory
8408 device/include/pic16 and device/lib/pic16. These files
8409 contain the declarations of SFRs for the PIC18Fxx2 devices.
8410 The directory is initialized via configure from toplevel.
8412 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8414 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8415 the spilllocations to be compared correctly
8417 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8419 * src/SDCCast.c (decorateType): fixed bug introduced today
8421 2004-01-12 Borut Razem <borut.razem AT siol.net>
8423 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8426 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8428 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8429 in simpler and even better code
8431 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8433 * src/SDCCicode.c (operandOperation): fixed bug #874819

8437 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8439 * doc/sdccman.lyx: Moved and added some sections, small changes
8440 all over. Telling LaTeX to be less strict with word spacing
8441 to better keep the right margin. Changed some notes about
8442 maintainance of the ports in section 3.2.1 - is it OK like this?
8444 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8446 SDCC source changes:
8447 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8481 UPPER for immediate operands,
8482 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8484 * src/pic16/peeph.def: all peepholes with movff are commented out,
8485 because there is a problem in the pcode peep optimizer,
8486 * src/pic16/ralloc.c: the register allocator can now reuse local
8487 function symbols for another function. This saves register usage.
8488 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8490 Added file src/pic16/NOTES with information about program writing on
8491 the current port version.

8500 * src/SDCCmain.c : fixed #872250: -l command line defined library
8501 files are scanned before standard library files
8503 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8520 gen51Code): more efficient parameter receive for --model-large
8523 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8526 * src/z80/main.c: added missed needLinkerScript flags (more than
8527 one port structure defined in these file)
8528 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8544 needLinkerScript flag
8546 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8547 * src/pic/glue.c: added variable udata_section_name to
8548 override default uninitialized data segment definition for
8549 devices only with SHAREBANK memory (reported from Erik Epetrich)
8550 * (pic14emitOverlay): modified to emit a commented overlay segment
8551 directive when no overlay data exist
8552 * (picglue): modified to emit uninitialized data segment
8553 according to udata_section_name

8558 arguments via -W option
8559 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8560 object file from '.rel' to '.o' in port->linker structure,
8561 changed size of fptr from 2 to 3 in port structure
8563 2004-01-07 Borut Razem <borut.razem AT siol.net>
8565 * support/scripts/sdcc.nsi: update PATH
8566 * support/scripts/sdcc.ico: craeted
8568 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

8571 * doc/Makefile: fix install
8573 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8575 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8577 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8579 include information about variables allocated to the overlay
8582 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8584 * as/mcs51/lkmain.c: Help about -Y option

8596 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8598 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8599 (default behaviour).
8601 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8603 A python script to validate compiler diagnostic messages. It can be
8604 used to verify that sdcc complains about bad c source code and
8605 gives a good location of the error.
8606 * support/valdiag/Makefile,
8607 * support/valdiag/valdiag.py,
8608 * support/valdiag/tests/*
8610 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8612 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8621 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8623 * src/common.h: added ifndef/define/endif macros
8624 around the header file.
8625 Bug reported from Jesus Calvino-Fraga
8627 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8629 * sdcc.spec: updated
8630 * device/include/Makefile.in: don't install CVS directories
8631 * device/lib/Makefile.in: added removal of CVS directories after install
8632 * doc/Makefile: fixed install, added local_icons
8633 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8634 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8635 * src/ds390/gen.c (genRightShift): fixed bug #870788
8636 * src/SDCCast.c (decorateType): fixed bug #870781
8638 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8640 PIC16 port related changes:
8641 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8642 added variable stackPos,
8644 * gen.c: genCall, assignResultValue: added support for
8645 pushing/retrieving function parameters to/from stack,
8646 genFunction,genEndFunction: setup stack frame for the
8648 genAddrOf: will be changed according to bug 863624
8650 * added files genutils.c and genutils.h which contain gen*
8651 debugged and optimised functions extracted from gen.c
8653 * glue.c: added variable 'externs' which holds extern symbols,
8654 pic16emitRegularMap: is modified to properly handle relocatable
8655 symbols under the new scheme,
8656 pic16createInterruptVect: is modified
8657 pic16printPublics: is modified to emit 'global' assembler directives,
8658 added pic16_printExterns to print extern symbols,
8659 pic16glue: initializes stack/frame pointer in the beginning of
8660 the assembly output. Temporary hack, will be corrected later,
8661 because gplink yet does not support stack and SDCC does not
8662 yet support a type of crt0.o object to create the final binary.
8664 * Removed many lines that contain 8051 legacy code.
8665 * The code is finally placed under a 'code' directive.
8666 * Added port specific options.
8668 * _process_pragma: simplified since now we do not need *special*
8669 include file to define SFR registers. But a separate header
8670 will be needed. This will be developed later.
8671 * _pic16_parseOptions: added, parses port specific options:
8672 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8673 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8674 --preplace-udata-with=
8676 * _pic16_setDefaultOptions: modified to initialize section names,
8677 but hack is temporarly out of order since it needs improvement.
8678 * _pic16_genAssemblerPreamble: configuration words are emitted by
8679 their address instead of their name. This part is incomplete and
8680 supports only the 18Fxx2 devices. Other devices will emit an error
8681 during assembly since they do not contain the same set of config
8683 * _pic16_genIVT: is modified,
8685 * pcode.c: added definitions for some hardware registers that are needed
8687 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8688 All PCI entries are updated. Now LFSR is supported.
8689 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8690 * added pic16_newpCodeOpLit2 to support instructions with
8691 two literal arguments
8692 * pic16_pCode2str: corrected code that emits assembler instructions
8693 with two literal operands and those that have an access bit modifier
8694 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8695 this fixes a bug which caused some labels to be lost, when an
8696 assembler directive was added, i.e. banksel,
8697 * pic16_FixRegisterBanking: improved logic that causes the insertion
8699 * InlineFunction: functions that are called once, are not any more
8700 inlined. This can be a port option in the future,
8702 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8704 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8705 hold the corresponding uninitialized symbols,
8706 * pic16_allocProcessorRegister: registers have explicit marked the
8708 * pic16_allocInternalRegister: registers are explicit marked as
8710 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8711 processing list, so bit registers were lost,
8714 * ralloc.h: added field 'accessBank' and original symbol operand
8715 in register definition,
8716 * removed the field isMapped from register definition,
8718 ** Several functions have been removed from various sources:
8719 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8720 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8721 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8722 pic16_assignRelocatableRegisters
8724 ** others have been introduced:
8725 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8726 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8728 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8730 * support/scripts/inc2h.pl: changed definition of BIT_AT
8731 to emit 'sbit at' instead of 'bit at'. This was a request.
8733 PIC16 port related preliminary changes:
8734 * gen.c: prefixed function popRegFromString with
8735 pic16_ and all references to it corrected
8736 * pcode.c: all pic16_pc_* hardware registers prefixed
8737 with underscore (_),
8738 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8739 * ralloc.c: newReg(): when register is REG_SFR then
8740 set address to rIdx,
8741 pic16_allocProcessorRegister(): marks register wasUsed=0
8742 pic16_writeUsedRegs(): added a call to assign processor
8743 registers via pic16_assignFixedRegisters
8745 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8747 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8748 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8749 variables in unused register banks. Also the SSEG is placed
8750 wherever there is enough space for it, and IDATA can be anywhere
8751 in internal RAM. For now compile using -Wl-Y[stack_size].
8752 The mem file is different for this option as well, since it

9751 iCode properly now. Use getSize instead of nRegs since a & b
9752 aren't part of the nRegs tally.
9754 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9756 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9757 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
9758 before instructions that use the _STATUS register
9760 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9762 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9763 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9764 fetching of the pointer
9765 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9766 copied from genNearPointerSet()
9767 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9768 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9769 If they pop r0/r1 they must be called in the opposite order than aopOp().
9770 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9771 (resp. --stack-auto), prepared for --xstack

9777 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9779 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9780 these ports have their own __sdcc_external_start()
9782 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9784 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9785 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9786 type for bits was changed. It resulted in bit variables becoming
9787 global, which is not permitted in PIC 14 assembly output.
9789 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9791 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9793 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9795 Z80 and MCS51 linkers complaint if a public symbol is defined

9804 A few small changes that speed up the peephole optimizer.
9808 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9810 Try to make the peephole optimizer smarter by maintaining
9811 an association between the assembly source code and the
9812 iCodes that originated them. Put this information to use
9813 with a new peephole rule condition "notVolatile" so that
9814 the rules can be aggressive yet still safe.
9819 * src/mcs51/peeph.def
9821 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9825 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9826 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9827 if the left or right operand symbols have the accuse flag set.
9829 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9831 Changed the type of the result of the ! (NOT) operator to char;
9832 previously it returned the same type as the source. This allows
9833 us to eliminate all the genFloatNot functions (all of its target
9834 implementations were very buggy) since !float can use the same
9837 * src/SDCCicode.c (ast2iCode): ! returns char

9846 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9847 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9848 during interrupts. Ensure WSAVE is located at a shared bank address.
9849 2. Fixed page selection in some places
9850 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9851 the registers name strings.
9852 4. Fixed "signed / unsigned compare" compiler warnings.
9853 5. The PIC port manages its own allocation of the general purpose
9854 registers, but makes no attempt to reuse them. As a result when
9855 compiling it soon runs out of general purpose registers. Some
9856 additional code was added to the files pcode.c and device.c to walk
9857 through the function call tree and rename the registers so that they
9867 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9868 genPlus() & genMinus() when the result is the same as left or right

9874 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9876 Made bitfield a distinct type from bit so that bitfields
9877 convert as per ANSI C and bits retain their traditional
9878 boolean style behaviour. Implemented bitfield support in
9886 * src/ds390/gen.c: bit v bitfield split
9887 * src/z80/gen.c: New support for bitfields
9888 * support/regression/tests/bitfields.c: reenabled z80,
9891 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9893 Rules 246.x, 247.x relate to bitfields, the others speed up
9894 access to xdata mapped I/O devices.
9896 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9898 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9900 Cleaned up genPackBits and genUnpackBits and added two helper
9901 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9902 for literal assignments in genPackBits (thanks to Frieder for
9908 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9910 Fixed bug #748310 (pointer to function type mishandled when the
9911 function name is omitted). Also fixed a SIGSEGV when a function
9912 attribute (reentrant, etc) is used on a non-function or on a
9913 function but misplaced before the parameter list.
9915 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9917 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9918 * support/Util/SDCCerr.h,
9919 * support/Util/SDCCerr.c: Added func attr misuse error msg

9940 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9942 Made the constant following the "interrupt" keyword optional. If
9943 omitted, the function will not automatically be given an entry
9944 in the interrupt vector table (similar to #pragma NOIV, but
9945 less syntacticly kludgy). The interrupt number is also now
9946 range checked. Also fixed a bug in the high order bit example

9960 * src/SDCCicode.c (operandOperation): rewritten some ops
9961 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9962 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9964 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9965 be re-activated by defining REDUCE_LITERALS)
9966 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9967 unsigned, but are signed by default
9968 * src/SDCCval.c (constVal): rearranged
9969 * src/SDCCval.c (valMod): preliminary fix
9970 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10012 constants are unsigned; added recognition of "u" flag for unsigned
10013 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10014 * src/SDCCval.c (valDiv, valMod): fixed signdness

10422 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10423 the regression tests I'm not brave enough to enable 245.b, 245.c
10424 * doc/sdccman.lyx: added latex preamble for hyperref package.
10425 Using pdflatex this will give you a hyperlinked pdf file with
10426 bookmarks. (prepend '%' before /usepackage if this breaks something)

10467 it can be defined with CFLAGS when running configure
10468 * src/SDCCmain.c: fixed compiling + linking with object files
10470 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10475 * src/SDCCmain.c: linkOptions is changed to set *,
10476 added if/endif conditional macros to remove options help
10477 messages from optionsTable when a port is not configured, added
10478 support for the PIc16 port in the ports table, when executing
10479 the compiler with no port specified on command line, a default
10480 port is selected with the new macro DEFAULT_PORT which is
10481 defined in port.h, in setDefaultOptions() linkOptions is removed
10482 from initialization assignment, since now it is a set,
10483 parseCmdLine uses setParseWithComma for linkOptions, in
10484 linkEdit() linkOptions are accessed with new function indexSet()
10485 which returns the i'th item of a set variable. See SDCCset.c, in
10486 linkEdit() when calling buildCmdLine(), added linkOptions as
10487 last argument. Now users can pass arguments to gplink via the
10488 -Wl option, main() uses pic16glue() to glue up pic16 programs
10489 * src/SDCCpeeph.c: various changes to support pic16
10490 * src/SDCCset.c: added function void *indexSet(set *, int) to

10500 * src/pic16/glue.c: commented out some error producing lines
10501 * src/pic16/main.c: __config directives are commented out to stop
10502 gpasm complaining and test the linkage with gplink, _linkCmd and
10503 _asmCmd changed to be more gplink and gpasm friendly
10504 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10505 produced an error when parsed, peep rule 12 is added to utilize
10506 movff, but it is commented out since the pCode does not support
10507 yet a command with 2 address arguments
10509 2003-05-18 <johan AT balder>
10511 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11588 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11590 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11593 2002-09-18 <wiml AT hhhh.org>
11595 * SDCClrange.h: exposed setFromRange() and setToRange()
11596 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11597 packRegsForAccUse() (bug 542397)
11598 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11599 multiple times and emitting the fetch operations more than once
11600 added aopGetUsesAcc() function to allow binary operators to
11601 fetch their operands in the correct order; made genMinus() emit
11602 compact code for X = LITERAL - Y
11604 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11605 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11606 sprintf() in line 1267.
11608 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11609 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11612 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11613 Changes to aslink (All the changes are marked with 'JCF'):
11615 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11618 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11619 area BSEG. Also moves, if possible, the DATA area down into the internal
11620 ram so more space is available.
11622 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11625 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11626 not bytes. Function summary() which creates a memory usage summary
11627 file with extension .mem. Reports of overlaping stack and small stack
11628 size. If the space for the stack is less than 16 bytes aslink trows a
11631 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11632 the 8051. Option 'y' for memory summary output file.
11634 Changes to sdcc (All the changes are marked with 'JCF'):
11636 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11638 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11639 overlaying area for it (uses RegBankUsed[4]).
11641 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11642 bank zero as used by default. By default aslink locates the stack
11643 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11644 the creation of the .mem file. Delegates the allocation of data area
11645 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11646 the begining of the stack area to aslink.
11648 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11649 glue() in SDCCglue.c creates an area for it.
11651 2002-09-03 Borut Razem <borut.razem AT siol.net>
11652 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11653 sdcc/src/pic/glue.c:
11654 introduced atexit() handler for teporay files removal in case of
11655 errors, assertions, ...
11657 2002-08-29 Borut Razem <borut.razem AT siol.net>
11658 * sdcc/support/cpp2/auto-host_vc_in.h:
11659 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11660 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11661 Maybe there is a similar problem with BORLANDC? It should be checked!
11663 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11664 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11665 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11666 was not executed, and the compiler (cl) launched a warning:
11667 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11669 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11670 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11672 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11673 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11675 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11676 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11677 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11678 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11679 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11680 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11681 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11682 - added Release configuration in VS projects
11683 - review of compiler an linker options
11684 - VC .exe files are generated in bin_vc directory, not to interfere
11685 with binaries generated from other projects (cygwin, mingw, bcc ...)
11687 * sdcc/src/yacc.dsp: added
11689 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11690 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11691 and insert the version number definitions from .version
11693 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11695 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11696 added - genarate auto-host.h using auto-host_vc_in.h as template
11699 removed from CVS, generated automatically
11701 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11702 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11704 2002-08-11 Borut Razem <borut.razem AT siol.net>
11705 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11707 2002-08-10 Borut Razem <borut.razem AT siol.net>
11708 * src/SDCCmain.c (main):
11709 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11710 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11711 The consequence was that some temporary files were not removed.
11714 unification of code in functions tempfilename() and tempfile():
11715 function tempnam() is defined in Visual Studio 6.0 and .NET
11717 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11719 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11720 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11721 - removed compiler command line option /WX: Treats all warnings as errors
11722 - update a list of source files, included into the project
11724 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11725 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11726 changed project type to Generic Project so that can be correcly converted to VS.NET project
11728 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11730 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11732 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11734 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11735 added return 0 statements after assert() to make compiler happy
11737 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11738 added newline in the def file to keep MSC compiler satisfied
11740 * sdcc/src/z80/gen.c:
11741 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11742 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11743 - solved MSC error in function aopDump()
11745 * sdcc_vc.h: define PREFIX as "\\sdcc"
11747 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11748 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11751 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11752 - Rewrote the register banking algorithm.
11753 - Added pCode live-range analysis to registers (for now, only non-used and
11754 singly-used registers optimized away)
11756 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11758 * 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.

11783 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11785 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11787 2002-03-28 Johan Knol <johan AT balder>
11789 * src/SDCCval.c: fixed bug #532436
11791 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11793 Added "char *Processor" field to the port structure.
11796 Added -p option. Allows port dependent processor to be specified.
11799 Initialized the new field char *Processor field to NULL in all ports
11802 Compiler generated registers for interrupt context saving
11803 were not getting allocated.
11805 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11808 Fixed left shift. Will promote the left side of a left shift
11809 if a) left shifting more than size of operand or b) when assigned
11810 to something size > size of left side
11812 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11816 analysis is restructured. ...
11818 * src/pic/device.h:
11821 * src/pic/device.c:
11822 Added. device.c is a PIC port hack to accomodate variations
11825 2002-03-13 Michael Hope <michaelh AT vroom>
11827 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11829 2002-03-04 johanknol <johanknol AT manik>
11831 * /src/SDCCval.c: fixed
11833 const unsigned char arr[][2] = { { 0, 1 } };

11920 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11922 * sdcc/src/SDCCloop.c:
11923 Previous fix was not good. basic blocks that have "break" or "return" are
11924 not really partof a loop , but live ranges used in these blocks should
11925 be live thru the entire loop, so set partOfLoop but don't add them to
11928 2002-02-21 <johan AT FRIJA>
11930 * src/SDCCcse.c: fixed bug #514308
11932 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

11936 statement inside a loop, it was not being considered part of the loop.
11938 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11940 2002-02-10 Karl Bongers <karl AT turbobit.com>
