1689 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1691 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1692 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1694 One basic decision: e.g. src/clean.mk includes further files. In order
1695 to make this work there are two solutions:
1696 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1697 run configure on them. This way they can use
1698 'include $(srcdir)/port-clean.mk'
1699 - always include clean.mk by the Makefile at the same level. To avoid
1700 that `make clean` tries to include and build Makefile.dep the
1701 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1702 implemented, because now even `make uninstall` doesn't create
1703 Makefile.in. clean.mk could be eliminated by pasting it in
1706 * debugger/mcs51/Makefile.in: build own objects from library sources
1707 (SLIB, SDCC) in current directory
1709 * configure, configure.in: renamed --disable-device-lib-build in
1710 --disable-device-lib; added --enable-doc, the required tools are
1711 searched by configure; added result message; the toolchain for the
1712 belonging ports are now only built, if the port is enabled.
1714 * support/regression/*: all output is written in directory gen, because
1715 the fwk and ports directories don't livet in the build tree using vpath
1717 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1718 --disable-device-lib, added --enable-doc, added section VPATH
1720 * sim/ucsim/configure.in,
1721 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1722 z80 are enabled by default
1724 2006-04-24 Raphael Neider <rneider AT web.de>
1726 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1727 to config word, "pic14_"-prefixed some extern functions
1728 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1729 config word has been found
1730 * src/pic/device.h: added prototypes
1731 * src/pic/pcode.c: added "pic14_"-prefix where needed
1732 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1734 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1736 (pic14emitRegularMap): ignore config words,
1737 (pic14createInterruptVect): moved generating __config directives away
1738 (picglue): have __config directives emitted
1740 2006-04-24 Borut Razem <borut.razem AT siol.net>

1744 2006-04-24 Raphael Neider <rneider AT web.de>
1746 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1747 registers that have not been assigned proper liveranges,
1748 fixes #1469504 and #1474602,
1749 (pCodeRegOptimizeRegUsage): fixed typo in comment
1751 2006-04-24 Borut Razem <borut.razem AT siol.net>
1753 * device/examples/main8051.c: deleted - it was removed from CVS
1754 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1755 after the transition to Subversion
1756 * src/SDCCalloc.h: deleted - it was removed from CVS
1757 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1997 and enabled nesting of critical functions though not for gbz80
1998 (genCritical, genEndCritical): added functions
1999 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2000 * src/z80/mappings.i: added "ei" to all mappings

2017 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2019 * src/.version: increased version number to 2.5.5
2020 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2021 linking is done manually in pic16 port's _linkEdit,
2022 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2023 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2024 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2025 allocate asmop as AOP_ACC,
2026 (aopForRemat): added parameter 'bool result' in function declaration,
2027 (pic16_aopGet): return AOP_ACC when accessing WREG,

2039 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2040 call to allocReg, not by manually allocating a new one,
2041 (pic16_assignRegisters): now before going through the register
2042 allocating functions mark all registers as free. This eliminates some
2043 side effects resulting from peephole parser done earlier in the backbone

2103 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2104 which dumps before the function entry point a data byte which represents
2105 the number of the local variables used by the specified function, added
2106 'xinst' for initial support for Extended Instruction Support,
2107 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2108 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2109 port->fun_prefix anymore (may change later),
2110 (genFunction, genEndFunction): do not store/restore local registers for
2111 _main (this should take care the --main-return command line option in
2113 (genOr): removed some legacy pic-port instructions,
2114 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2115 performing operations with SFR's causes data to be written more than
2116 once to each SFR. Perhaps SFRs should be handled in special cases...
2117 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2119 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2124 (deassignLRs): *** perhaps the most important change, old 'for' code
2125 (commented out for reference), didn't account for some registers which
2126 were left marked 'not free' after a pointer operation. The change
2127 reduces register usage a lot in some cases

4404 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4405 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4406 always available in leading double underscore form. The C99 support is
4407 mostly missing, but it's a start.
4408 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4489 * device/lib/printf_large.c: removed inline assembly for portability and
4490 readability. Use printf_fast if speed or size are more important.
4491 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4492 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4494 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4496 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4497 prevent compiler warning
4499 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4501 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4502 moved to level 0 and declared as static. Also they are explicit
4503 placed in access bank. This was necessery because some times they
4504 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4505 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4506 optimizations. Currently only compare to unsigned char is implemented,
4507 * src/pic16/gen.c: added fReturnIdx array,
4508 * (struct resolvedIfx) is moved to gen.h and made public,
4509 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4510 * (aopForSym): added an optimization to directly store in stack of
4511 the operand of a SEND iCode,
4512 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4513 but as registers instead (AOP_REG) using the fReturnIdx array,
4514 * (pic16_freeAsmop): remove the freed register from the
4515 _G.sregsAlloc field,
4516 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4517 a compare of 'WREG',
4518 * (pic16_popGetTempRegCond): changed function prototype, now
4519 function takes also a bitVector argument v which holds the current
4520 set of registers that are allocated for stack access by aopForSym,
4521 registers allocated in aopForSym for accessing stack symbols are not
4522 any more part of the functions usedRegs field,
4523 * (genCall): some times aopOp is called for a stack variable to be
4524 send, aopForSym might perform the push, if this is true make sure
4525 that genCall doesn't push the variable twice by testing _G.resDirect,
4526 * (genFunction): changed testing for unspecified interrupt number
4527 from 256 to INTNO_UNSPEC,
4528 * modified selection scheme of frame pointer generation. Previously
4529 if function did use local registers a frame pointer was generated,
4530 now a frame pointer is generated only if function has arguments
4531 (that need PLUSW2 register access), or has stack arguments, or the
4532 compiler is not instructed to omit the frame pointer,
4533 * (genEndFunction): before restoring local registers that were saved
4534 in the function preamble, also restore the registers that *might*
4535 have been allocated for stack access,
4536 * (genRet): removed some old comments,
4537 * (genCmp, the active (RN's) version): added a call to the
4538 pic16_genCmp_special function to perform the compare with a more
4539 robust and optimized way,
4540 * (genInline): a feature has been added in inline code generation,
4541 which allows a wildcard variable substitution when writing inline
4542 assembly. Code is incomplete and experimental therefore undocumented,
4543 * (genCast): changed order of aopOp for result and right to allow
4544 aopForSym to directly load the result if possible,
4545 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4546 perform an optimized compare on some selected special occasions,
4547 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4548 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4549 generate an IVT any more,
4550 * src/pic16/main.c (pic16_optionsTable): added command line option
4552 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4553 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4555 * src/pic16/NOTES: Raphael Neider added in list of active developers
4556 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4557 jumptable_end to prevent bug #,
4558 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4559 inCond and outCond fields,
4560 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4561 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4562 turn off register spilling,
4563 * (packRegsForOneUse): synced with other ports' versions although it
4564 is not used currently,
4565 * (pic16_packRegisters): added an optimization while reading
4566 structure bitfields, some registers may be saved (malloc code is
4567 decreased by 80 bytes)
4569 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4571 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4572 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4573 this can be optimized more?
4575 2005-03-10 Raphael Neider <rneider AT web.de>
4577 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4578 genNearPointerGet): (hopefully) fixed access to bitfields via
4579 pointers (p->bitN = x; and x = p->bitN; failed)
4581 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5211 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5213 Adding support for replacing ljmps with sjmps in jumptables
5214 generated for switch statements. For now you need to set the
5215 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5216 Now 4 algorithms for mcs51 jumptable generation are used:
5217 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5218 addresses loaded pc-relative for up to 112 cases and stack-pushing
5219 target addresses loaded with offset from dptr for up to 256 cases.
5221 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5222 * src/mcs51/main.c: adapted constants for switch table generation

5246 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5247 to call when a stack overflow occurs,
5248 * (malloc.h): added CVS Id tag,
5249 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5251 * added libc directory. The current version of LibC contains string
5252 functions, ctype functions and macros and some functions of the
5253 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5254 be extensively tested in the future. Standard disclaimer here.
5255 Library is not automatically build yet. But one can build it by
5256 invoking 'make' inside the libc directory.
5257 * added ADC library under libio. Preliminary version yet.
5259 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5263 temporary registers, its a buggy feature and will be removed,
5264 * (pic16_popGet): set register instance field in AOP_CRY,
5265 * (pic16_outBitC): fixed for results in size greater than 1,
5266 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5267 * (pic16_storeForReturn): optimized return of 0,
5268 * (genCmp): experimental code for new genCmp which uses PIC18's
5269 special compare&skip instructions. Initial tests fail some times
5270 with variables grater than 1 byte in size, so new code is disabled,
5271 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5273 * (genCast): began a fix to optimize the casting of a bit to another
5274 bit, now assigning a bitfield to another bitfield will fail, sorry,
5275 * src/pic16/main.c: disabled the use of lr-support feature,
5276 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5277 * added some function prototypes, added function _debugf prototype,

5279 bits with offset (case PO_GPR_BIT),
5280 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5282 * (isBankInstruction): modified to return 0 for no banking instruction,
5283 and 1 for banking instruction,
5284 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5285 caused stop processing pCodes after a inline assembly block,
5286 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5287 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5288 registers when it shouldn't,
5289 * src/pic16/ralloc.c (allocReg): add preliminary support for
5290 supporting a limited set of temporary registers,
5292 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5294 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5295 genDataPointerSet): ensure assignments always copy in MSB to LSB
5297 (loadRegFromAop): recognize CLRH optimization,
5298 (genFunction): optimize RECEIVE iCodes in reentrant functions
5300 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5302 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8297 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8299 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8300 loaded with the linker search paths (-L arguments) and the libraries
8301 to be linked with the current source (-l arguments). Changes
8302 currently will affect only the pic16 port.
8303 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8304 include path the port specific paths and port specific libraries,
8305 * gplink command now contains the $3 argument,
8306 * src/pic16/device.h,
8307 * src/pic16/device.c,: structure PIC_device is made public and
8308 renamed to PIC16_device, the same for variable Pics which is renamed
8309 to Pics16. Updated all references to them.
8310 * src/pic16/glue.c (pic16glue): corrected bug with code
8311 initialization which bypassed the variable initializations block.

8321 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8323 Documenting changes from previous commits.
8324 * configure.in (version 1.56),
8325 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8326 when generating output files to configure the pic16 library,
8327 but now I've commented it out, since gputils aren't installed in the
8328 SF compile farm, so library won't compile
8330 * device/lib/Makefile.in (version 1.56): initially I've added in
8331 target 'all' the prerequestive 'model-pic16' so it compiled the
8332 pic16 library, but now I've commented it out for the same reasons
8334 * added targets 'model-pic16' and 'objects-pic16' to compile the
8336 * added target 'port-specific-objects-pic16' to handle the
8337 generated libraries and copy them into the build/ directory
8338 * added target 'clean-intermediate-pic16' to clean intermediate
8339 files into pic16 directory
8340 * in target 'installdirs' added line to create directory pic16 in
8341 the installation path
8343 * device/include/Makefile.in (version 1.11): in target 'install'
8344 added lines to copy all header files to installation path,
8345 * in target 'installdirs' added line create directory for pic16
8346 headers in the installation path

8361 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8362 option so that it actually works. Made it specific to the z80, since
8363 the gbz80 doesn't have these kinds of I/O ports.
8365 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8367 * device/include/z180.h,

8380 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8382 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8383 changed interrupt vector table generation to only emit declared vectors.
8384 * device/include/Makefile.in: added missing backslash
8385 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

8389 Mainly changes to support compilation of the device libraries
8390 * src/pic16/device.c: stack is allocated via symbol and not
8391 via literal number. The symbol is placed in the corresponding
8392 position of the data ram
8393 * (pic16_dump_section): relocatable and absolute uninitialized
8394 data are now emitted in sorted order to reduce section naming,
8395 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8396 weren't marked as being in the access bank,
8398 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8400 Added portion of GNU PIC Library under the directory
8401 device/include/pic16 and device/lib/pic16. These files
8402 contain the declarations of SFRs for the PIC18Fxx2 devices.
8403 The directory is initialized via configure from toplevel.
8405 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8407 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8408 the spilllocations to be compared correctly
8410 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8412 * src/SDCCast.c (decorateType): fixed bug introduced today
8414 2004-01-12 Borut Razem <borut.razem AT siol.net>
8416 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8421 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8422 in simpler and even better code
8424 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8426 * src/SDCCicode.c (operandOperation): fixed bug #874819

8430 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8432 * doc/sdccman.lyx: Moved and added some sections, small changes
8433 all over. Telling LaTeX to be less strict with word spacing
8434 to better keep the right margin. Changed some notes about
8435 maintainance of the ports in section 3.2.1 - is it OK like this?
8437 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8439 SDCC source changes:
8440 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8473 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8474 UPPER for immediate operands,
8475 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8477 * src/pic16/peeph.def: all peepholes with movff are commented out,
8478 because there is a problem in the pcode peep optimizer,
8479 * src/pic16/ralloc.c: the register allocator can now reuse local
8480 function symbols for another function. This saves register usage.
8481 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8483 Added file src/pic16/NOTES with information about program writing on
8484 the current port version.

8493 * src/SDCCmain.c : fixed #872250: -l command line defined library
8494 files are scanned before standard library files
8496 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8513 gen51Code): more efficient parameter receive for --model-large
8516 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8519 * src/z80/main.c: added missed needLinkerScript flags (more than
8520 one port structure defined in these file)
8521 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed
8524 2004-01-08 Vangelis Rokas <vrokas AT otenet.gr>

8537 needLinkerScript flag
8539 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8540 * src/pic/glue.c: added variable udata_section_name to
8541 override default uninitialized data segment definition for
8542 devices only with SHAREBANK memory (reported from Erik Epetrich)
8543 * (pic14emitOverlay): modified to emit a commented overlay segment
8544 directive when no overlay data exist
8545 * (picglue): modified to emit uninitialized data segment
8546 according to udata_section_name
8547 * src/pic/main.c (_pic14_parseOptions): added command line

8552 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8553 object file from '.rel' to '.o' in port->linker structure,
8554 changed size of fptr from 2 to 3 in port structure
8556 2004-01-07 Borut Razem <borut.razem AT siol.net>
8558 * support/scripts/sdcc.nsi: update PATH
8559 * support/scripts/sdcc.ico: craeted
8561 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
8563 * device/include/Makefile.in: fix install
8564 * doc/Makefile: fix install
8566 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8568 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8570 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
8571 how the function variable allocation summary is displayed; also
8572 include information about variables allocated to the overlay
8575 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8577 * as/mcs51/lkmain.c: Help about -Y option

8589 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8591 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8592 (default behaviour).
8594 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8596 A python script to validate compiler diagnostic messages. It can be
8597 used to verify that sdcc complains about bad c source code and
8598 gives a good location of the error.
8599 * support/valdiag/Makefile,
8600 * support/valdiag/valdiag.py,
8601 * support/valdiag/tests/*
8603 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8605 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8606 * src/SDCCsymt.c (newEnumType),

8614 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8616 * src/common.h: added ifndef/define/endif macros
8617 around the header file.
8618 Bug reported from Jesus Calvino-Fraga
8620 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8622 * sdcc.spec: updated
8623 * device/include/Makefile.in: don't install CVS directories
8624 * device/lib/Makefile.in: added removal of CVS directories after install
8625 * doc/Makefile: fixed install, added local_icons
8626 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8627 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8628 * src/ds390/gen.c (genRightShift): fixed bug #870788
8629 * src/SDCCast.c (decorateType): fixed bug #870781
8631 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8633 PIC16 port related changes:
8634 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8635 added variable stackPos,
8637 * gen.c: genCall, assignResultValue: added support for
8638 pushing/retrieving function parameters to/from stack,
8639 genFunction,genEndFunction: setup stack frame for the
8641 genAddrOf: will be changed according to bug 863624
8643 * added files genutils.c and genutils.h which contain gen*
8644 debugged and optimised functions extracted from gen.c
8646 * glue.c: added variable 'externs' which holds extern symbols,
8647 pic16emitRegularMap: is modified to properly handle relocatable
8648 symbols under the new scheme,
8649 pic16createInterruptVect: is modified
8650 pic16printPublics: is modified to emit 'global' assembler directives,
8651 added pic16_printExterns to print extern symbols,
8652 pic16glue: initializes stack/frame pointer in the beginning of
8653 the assembly output. Temporary hack, will be corrected later,
8654 because gplink yet does not support stack and SDCC does not
8655 yet support a type of crt0.o object to create the final binary.
8657 * Removed many lines that contain 8051 legacy code.
8658 * The code is finally placed under a 'code' directive.
8659 * Added port specific options.
8661 * _process_pragma: simplified since now we do not need *special*
8662 include file to define SFR registers. But a separate header
8663 will be needed. This will be developed later.
8664 * _pic16_parseOptions: added, parses port specific options:
8665 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8666 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8667 --preplace-udata-with=
8669 * _pic16_setDefaultOptions: modified to initialize section names,
8670 but hack is temporarly out of order since it needs improvement.
8671 * _pic16_genAssemblerPreamble: configuration words are emitted by
8672 their address instead of their name. This part is incomplete and
8673 supports only the 18Fxx2 devices. Other devices will emit an error
8674 during assembly since they do not contain the same set of config
8676 * _pic16_genIVT: is modified,
8678 * pcode.c: added definitions for some hardware registers that are needed
8680 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8681 All PCI entries are updated. Now LFSR is supported.
8682 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8683 * added pic16_newpCodeOpLit2 to support instructions with
8684 two literal arguments
8685 * pic16_pCode2str: corrected code that emits assembler instructions
8686 with two literal operands and those that have an access bit modifier
8687 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8688 this fixes a bug which caused some labels to be lost, when an
8689 assembler directive was added, i.e. banksel,
8690 * pic16_FixRegisterBanking: improved logic that causes the insertion
8692 * InlineFunction: functions that are called once, are not any more
8693 inlined. This can be a port option in the future,
8695 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8697 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8698 hold the corresponding uninitialized symbols,
8699 * pic16_allocProcessorRegister: registers have explicit marked the
8701 * pic16_allocInternalRegister: registers are explicit marked as
8703 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8704 processing list, so bit registers were lost,
8707 * ralloc.h: added field 'accessBank' and original symbol operand
8708 in register definition,
8709 * removed the field isMapped from register definition,
8711 ** Several functions have been removed from various sources:
8712 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8713 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8714 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8715 pic16_assignRelocatableRegisters
8717 ** others have been introduced:
8718 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8719 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8721 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8723 * support/scripts/inc2h.pl: changed definition of BIT_AT
8724 to emit 'sbit at' instead of 'bit at'. This was a request.
8726 PIC16 port related preliminary changes:
8727 * gen.c: prefixed function popRegFromString with
8728 pic16_ and all references to it corrected
8729 * pcode.c: all pic16_pc_* hardware registers prefixed
8730 with underscore (_),
8731 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8732 * ralloc.c: newReg(): when register is REG_SFR then
8733 set address to rIdx,
8734 pic16_allocProcessorRegister(): marks register wasUsed=0
8735 pic16_writeUsedRegs(): added a call to assign processor
8736 registers via pic16_assignFixedRegisters
8738 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8740 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8741 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8742 variables in unused register banks. Also the SSEG is placed
8743 wherever there is enough space for it, and IDATA can be anywhere
8744 in internal RAM. For now compile using -Wl-Y[stack_size].
8745 The mem file is different for this option as well, since it
8746 makes no sense of talking about DSEG lenght.
8748 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8750 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8751 in certain cases, e.g. when ROM assignment, patch provided
8752 from Albert den Haan.
8754 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>
8756 Many signedness and type propagation fixes:

9753 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9755 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9756 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9757 fetching of the pointer
9758 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9759 copied from genNearPointerSet()
9760 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9761 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9762 If they pop r0/r1 they must be called in the opposite order than aopOp().
9763 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9764 (resp. --stack-auto), prepared for --xstack
9766 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9773 these ports have their own __sdcc_external_start()
9775 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9777 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9778 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9779 type for bits was changed. It resulted in bit variables becoming
9780 global, which is not permitted in PIC 14 assembly output.
9782 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9784 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9786 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9788 Z80 and MCS51 linkers complaint if a public symbol is defined
9789 in more than one library module:

9797 A few small changes that speed up the peephole optimizer.
9801 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9803 Try to make the peephole optimizer smarter by maintaining
9804 an association between the assembly source code and the
9805 iCodes that originated them. Put this information to use
9806 with a new peephole rule condition "notVolatile" so that
9807 the rules can be aggressive yet still safe.
9812 * src/mcs51/peeph.def
9814 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9818 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9819 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9820 if the left or right operand symbols have the accuse flag set.
9822 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9824 Changed the type of the result of the ! (NOT) operator to char;
9825 previously it returned the same type as the source. This allows
9826 us to eliminate all the genFloatNot functions (all of its target
9827 implementations were very buggy) since !float can use the same
9830 * src/SDCCicode.c (ast2iCode): ! returns char
9831 * src/mcs51/gen.c (genNot, genNotFloat),
9832 * src/ds390/gen.c (genNot, genNotFloat),
9833 * src/z80/gen.c (genNot, genNotFloat),
9834 * src/pic/gen.c (genNot, genNotFloat),
9835 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9837 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9839 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9840 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9841 during interrupts. Ensure WSAVE is located at a shared bank address.
9842 2. Fixed page selection in some places
9843 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9844 the registers name strings.
9845 4. Fixed "signed / unsigned compare" compiler warnings.
9846 5. The PIC port manages its own allocation of the general purpose
9847 registers, but makes no attempt to reuse them. As a result when
9848 compiling it soon runs out of general purpose registers. Some
9849 additional code was added to the files pcode.c and device.c to walk
9850 through the function call tree and rename the registers so that they
9860 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9861 genPlus() & genMinus() when the result is the same as left or right

9867 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9869 Made bitfield a distinct type from bit so that bitfields
9870 convert as per ANSI C and bits retain their traditional
9871 boolean style behaviour. Implemented bitfield support in
9879 * src/ds390/gen.c: bit v bitfield split
9880 * src/z80/gen.c: New support for bitfields
9881 * support/regression/tests/bitfields.c: reenabled z80,
9884 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9886 Rules 246.x, 247.x relate to bitfields, the others speed up
9887 access to xdata mapped I/O devices.
9889 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9891 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9893 Cleaned up genPackBits and genUnpackBits and added two helper
9894 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9895 for literal assignments in genPackBits (thanks to Frieder for
9901 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9903 Fixed bug #748310 (pointer to function type mishandled when the
9904 function name is omitted). Also fixed a SIGSEGV when a function
9905 attribute (reentrant, etc) is used on a non-function or on a
9906 function but misplaced before the parameter list.
9908 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9910 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9911 * support/Util/SDCCerr.h,

9933 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9935 Made the constant following the "interrupt" keyword optional. If
9936 omitted, the function will not automatically be given an entry
9937 in the interrupt vector table (similar to #pragma NOIV, but
9938 less syntacticly kludgy). The interrupt number is also now
9939 range checked. Also fixed a bug in the high order bit example
9946 * support/Util/SDCCerr.c
9947 * support/Util/SDCCerr.h
9950 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9953 * src/SDCCicode.c (operandOperation): rewritten some ops
9954 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9955 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9957 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9958 be re-activated by defining REDUCE_LITERALS)
9959 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9960 unsigned, but are signed by default
9961 * src/SDCCval.c (constVal): rearranged
9962 * src/SDCCval.c (valMod): preliminary fix
9963 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10415 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10416 the regression tests I'm not brave enough to enable 245.b, 245.c
10417 * doc/sdccman.lyx: added latex preamble for hyperref package.
10418 Using pdflatex this will give you a hyperlinked pdf file with
10419 bookmarks. (prepend '%' before /usepackage if this breaks something)

10460 it can be defined with CFLAGS when running configure
10461 * src/SDCCmain.c: fixed compiling + linking with object files
10463 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10468 * src/SDCCmain.c: linkOptions is changed to set *,
10469 added if/endif conditional macros to remove options help
10470 messages from optionsTable when a port is not configured, added
10471 support for the PIc16 port in the ports table, when executing
10472 the compiler with no port specified on command line, a default
10473 port is selected with the new macro DEFAULT_PORT which is
10474 defined in port.h, in setDefaultOptions() linkOptions is removed
10475 from initialization assignment, since now it is a set,
10476 parseCmdLine uses setParseWithComma for linkOptions, in
10477 linkEdit() linkOptions are accessed with new function indexSet()
10478 which returns the i'th item of a set variable. See SDCCset.c, in
10479 linkEdit() when calling buildCmdLine(), added linkOptions as
10480 last argument. Now users can pass arguments to gplink via the
10481 -Wl option, main() uses pic16glue() to glue up pic16 programs
10482 * src/SDCCpeeph.c: various changes to support pic16
10483 * src/SDCCset.c: added function void *indexSet(set *, int) to

10493 * src/pic16/glue.c: commented out some error producing lines
10494 * src/pic16/main.c: __config directives are commented out to stop
10495 gpasm complaining and test the linkage with gplink, _linkCmd and
10496 _asmCmd changed to be more gplink and gpasm friendly
10497 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10498 produced an error when parsed, peep rule 12 is added to utilize
10499 movff, but it is commented out since the pCode does not support
10500 yet a command with 2 address arguments
10502 2003-05-18 <johan AT balder>
10504 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11591 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11592 multiple times and emitting the fetch operations more than once
11593 added aopGetUsesAcc() function to allow binary operators to
11594 fetch their operands in the correct order; made genMinus() emit
11595 compact code for X = LITERAL - Y
11597 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11598 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11599 sprintf() in line 1267.
11601 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11602 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11605 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11606 Changes to aslink (All the changes are marked with 'JCF'):
11608 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11611 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11612 area BSEG. Also moves, if possible, the DATA area down into the internal
11613 ram so more space is available.
11615 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11618 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11619 not bytes. Function summary() which creates a memory usage summary
11620 file with extension .mem. Reports of overlaping stack and small stack
11621 size. If the space for the stack is less than 16 bytes aslink trows a
11624 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11625 the 8051. Option 'y' for memory summary output file.
11627 Changes to sdcc (All the changes are marked with 'JCF'):
11629 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11631 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11632 overlaying area for it (uses RegBankUsed[4]).
11634 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11635 bank zero as used by default. By default aslink locates the stack
11636 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11637 the creation of the .mem file. Delegates the allocation of data area
11638 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11639 the begining of the stack area to aslink.
11641 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11642 glue() in SDCCglue.c creates an area for it.
11644 2002-09-03 Borut Razem <borut.razem AT siol.net>
11645 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11646 sdcc/src/pic/glue.c:
11647 introduced atexit() handler for teporay files removal in case of
11648 errors, assertions, ...
11650 2002-08-29 Borut Razem <borut.razem AT siol.net>
11651 * sdcc/support/cpp2/auto-host_vc_in.h:
11652 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11653 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11654 Maybe there is a similar problem with BORLANDC? It should be checked!
11656 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11657 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11658 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11659 was not executed, and the compiler (cl) launched a warning:
11660 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11662 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11663 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11665 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11666 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11668 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11669 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11670 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11671 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11672 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11673 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11674 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11675 - added Release configuration in VS projects
11676 - review of compiler an linker options
11677 - VC .exe files are generated in bin_vc directory, not to interfere
11678 with binaries generated from other projects (cygwin, mingw, bcc ...)
11680 * sdcc/src/yacc.dsp: added
11682 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11683 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11684 and insert the version number definitions from .version
11686 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11688 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11689 added - genarate auto-host.h using auto-host_vc_in.h as template
11692 removed from CVS, generated automatically
11694 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11695 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11697 2002-08-11 Borut Razem <borut.razem AT siol.net>
11698 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11700 2002-08-10 Borut Razem <borut.razem AT siol.net>
11701 * src/SDCCmain.c (main):
11702 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11703 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11704 The consequence was that some temporary files were not removed.
11707 unification of code in functions tempfilename() and tempfile():
11708 function tempnam() is defined in Visual Studio 6.0 and .NET
11710 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11712 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11713 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11714 - removed compiler command line option /WX: Treats all warnings as errors
11715 - update a list of source files, included into the project
11717 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11718 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11719 changed project type to Generic Project so that can be correcly converted to VS.NET project
11721 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11723 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11725 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11727 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11728 added return 0 statements after assert() to make compiler happy
11730 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11731 added newline in the def file to keep MSC compiler satisfied
11733 * sdcc/src/z80/gen.c:
11734 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11735 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11736 - solved MSC error in function aopDump()
11738 * sdcc_vc.h: define PREFIX as "\\sdcc"
11740 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11741 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11744 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11745 - Rewrote the register banking algorithm.
11746 - Added pCode live-range analysis to registers (for now, only non-used and
11747 singly-used registers optimized away)
11749 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11751 * 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.

11776 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11778 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11780 2002-03-28 Johan Knol <johan AT balder>
11782 * src/SDCCval.c: fixed bug #532436
11784 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11786 Added "char *Processor" field to the port structure.
11789 Added -p option. Allows port dependent processor to be specified.
11792 Initialized the new field char *Processor field to NULL in all ports
11795 Compiler generated registers for interrupt context saving
11796 were not getting allocated.
11798 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11801 Fixed left shift. Will promote the left side of a left shift
11802 if a) left shifting more than size of operand or b) when assigned
11803 to something size > size of left side
11805 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11807 tons of changes. Register allocation has been

11809 analysis is restructured. ...
11811 * src/pic/device.h:
11814 * src/pic/device.c:
11815 Added. device.c is a PIC port hack to accomodate variations
11818 2002-03-13 Michael Hope <michaelh AT vroom>
11820 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11822 2002-03-04 johanknol <johanknol AT manik>
11824 * /src/SDCCval.c: fixed
11826 const unsigned char arr[][2] = { { 0, 1 } };

11913 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11915 * sdcc/src/SDCCloop.c:
11916 Previous fix was not good. basic blocks that have "break" or "return" are
11917 not really partof a loop , but live ranges used in these blocks should
11918 be live thru the entire loop, so set partOfLoop but don't add them to
11921 2002-02-21 <johan AT FRIJA>
11923 * src/SDCCcse.c: fixed bug #514308
11925 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
