1729 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1731 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1732 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1734 One basic decision: e.g. src/clean.mk includes further files. In order
1735 to make this work there are two solutions:
1736 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1737 run configure on them. This way they can use
1738 'include $(srcdir)/port-clean.mk'
1739 - always include clean.mk by the Makefile at the same level. To avoid
1740 that `make clean` tries to include and build Makefile.dep the
1741 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1742 implemented, because now even `make uninstall` doesn't create
1743 Makefile.in. clean.mk could be eliminated by pasting it in
1746 * debugger/mcs51/Makefile.in: build own objects from library sources
1747 (SLIB, SDCC) in current directory
1749 * configure, configure.in: renamed --disable-device-lib-build in
1750 --disable-device-lib; added --enable-doc, the required tools are
1751 searched by configure; added result message; the toolchain for the
1752 belonging ports are now only built, if the port is enabled.
1754 * support/regression/*: all output is written in directory gen, because
1755 the fwk and ports directories don't livet in the build tree using vpath
1757 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1758 --disable-device-lib, added --enable-doc, added section VPATH
1760 * sim/ucsim/configure.in,
1761 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1762 z80 are enabled by default
1764 2006-04-24 Raphael Neider <rneider AT web.de>
1766 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1767 to config word, "pic14_"-prefixed some extern functions
1768 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1769 config word has been found
1770 * src/pic/device.h: added prototypes
1771 * src/pic/pcode.c: added "pic14_"-prefix where needed
1772 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1774 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1776 (pic14emitRegularMap): ignore config words,
1777 (pic14createInterruptVect): moved generating __config directives away
1778 (picglue): have __config directives emitted
1780 2006-04-24 Borut Razem <borut.razem AT siol.net>
1782 * doc/Makefile: sync with nightly build makefile
1784 2006-04-24 Raphael Neider <rneider AT web.de>

2037 and enabled nesting of critical functions though not for gbz80
2038 (genCritical, genEndCritical): added functions
2039 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2040 * src/z80/mappings.i: added "ei" to all mappings

2057 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2059 * src/.version: increased version number to 2.5.5
2060 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2061 linking is done manually in pic16 port's _linkEdit,
2062 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2063 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2064 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2065 allocate asmop as AOP_ACC,
2066 (aopForRemat): added parameter 'bool result' in function declaration,
2067 (pic16_aopGet): return AOP_ACC when accessing WREG,

2079 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2080 call to allocReg, not by manually allocating a new one,
2081 (pic16_assignRegisters): now before going through the register
2082 allocating functions mark all registers as free. This eliminates some
2083 side effects resulting from peephole parser done earlier in the backbone

2143 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2144 which dumps before the function entry point a data byte which represents
2145 the number of the local variables used by the specified function, added
2146 'xinst' for initial support for Extended Instruction Support,
2147 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2148 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2149 port->fun_prefix anymore (may change later),
2150 (genFunction, genEndFunction): do not store/restore local registers for
2151 _main (this should take care the --main-return command line option in
2153 (genOr): removed some legacy pic-port instructions,
2154 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2155 performing operations with SFR's causes data to be written more than
2156 once to each SFR. Perhaps SFRs should be handled in special cases...
2157 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2159 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2160 into account for stack starting position,

2164 (deassignLRs): *** perhaps the most important change, old 'for' code
2165 (commented out for reference), didn't account for some registers which
2166 were left marked 'not free' after a pointer operation. The change
2167 reduces register usage a lot in some cases
2169 2006-03-04 Borut Razem <borut.razem AT siol.net>

4442 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4443 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4444 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4445 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4446 always available in leading double underscore form. The C99 support is
4447 mostly missing, but it's a start.
4448 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4449 reserved identifier "__data".

4527 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4529 * device/lib/printf_large.c: removed inline assembly for portability and
4530 readability. Use printf_fast if speed or size are more important.
4531 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4532 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4534 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4536 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4537 prevent compiler warning
4539 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4541 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4542 moved to level 0 and declared as static. Also they are explicit
4543 placed in access bank. This was necessery because some times they
4544 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4545 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4546 optimizations. Currently only compare to unsigned char is implemented,
4547 * src/pic16/gen.c: added fReturnIdx array,
4548 * (struct resolvedIfx) is moved to gen.h and made public,
4549 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4550 * (aopForSym): added an optimization to directly store in stack of
4551 the operand of a SEND iCode,
4552 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4553 but as registers instead (AOP_REG) using the fReturnIdx array,
4554 * (pic16_freeAsmop): remove the freed register from the
4555 _G.sregsAlloc field,
4556 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4557 a compare of 'WREG',
4558 * (pic16_popGetTempRegCond): changed function prototype, now
4559 function takes also a bitVector argument v which holds the current
4560 set of registers that are allocated for stack access by aopForSym,
4561 registers allocated in aopForSym for accessing stack symbols are not
4562 any more part of the functions usedRegs field,
4563 * (genCall): some times aopOp is called for a stack variable to be
4564 send, aopForSym might perform the push, if this is true make sure
4565 that genCall doesn't push the variable twice by testing _G.resDirect,
4566 * (genFunction): changed testing for unspecified interrupt number
4567 from 256 to INTNO_UNSPEC,
4568 * modified selection scheme of frame pointer generation. Previously
4569 if function did use local registers a frame pointer was generated,
4570 now a frame pointer is generated only if function has arguments
4571 (that need PLUSW2 register access), or has stack arguments, or the
4572 compiler is not instructed to omit the frame pointer,
4573 * (genEndFunction): before restoring local registers that were saved
4574 in the function preamble, also restore the registers that *might*
4575 have been allocated for stack access,
4576 * (genRet): removed some old comments,
4577 * (genCmp, the active (RN's) version): added a call to the
4578 pic16_genCmp_special function to perform the compare with a more
4579 robust and optimized way,
4580 * (genInline): a feature has been added in inline code generation,
4581 which allows a wildcard variable substitution when writing inline
4582 assembly. Code is incomplete and experimental therefore undocumented,
4583 * (genCast): changed order of aopOp for result and right to allow
4584 aopForSym to directly load the result if possible,
4585 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4586 perform an optimized compare on some selected special occasions,
4587 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4588 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4589 generate an IVT any more,
4590 * src/pic16/main.c (pic16_optionsTable): added command line option
4592 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4593 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4595 * src/pic16/NOTES: Raphael Neider added in list of active developers
4596 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4597 jumptable_end to prevent bug #,
4598 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4599 inCond and outCond fields,
4600 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4601 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4602 turn off register spilling,
4603 * (packRegsForOneUse): synced with other ports' versions although it
4604 is not used currently,
4605 * (pic16_packRegisters): added an optimization while reading
4606 structure bitfields, some registers may be saved (malloc code is
4607 decreased by 80 bytes)
4609 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4611 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4612 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4613 this can be optimized more?
4615 2005-03-10 Raphael Neider <rneider AT web.de>
4617 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4618 genNearPointerGet): (hopefully) fixed access to bitfields via
4619 pointers (p->bitN = x; and x = p->bitN; failed)
4621 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5253 Adding support for replacing ljmps with sjmps in jumptables
5254 generated for switch statements. For now you need to set the
5255 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5256 Now 4 algorithms for mcs51 jumptable generation are used:
5257 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5258 addresses loaded pc-relative for up to 112 cases and stack-pushing
5259 target addresses loaded with offset from dptr for up to 256 cases.
5261 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

5286 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5287 to call when a stack overflow occurs,
5288 * (malloc.h): added CVS Id tag,
5289 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5291 * added libc directory. The current version of LibC contains string
5292 functions, ctype functions and macros and some functions of the
5293 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5294 be extensively tested in the future. Standard disclaimer here.
5295 Library is not automatically build yet. But one can build it by
5296 invoking 'make' inside the libc directory.
5297 * added ADC library under libio. Preliminary version yet.
5299 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5303 temporary registers, its a buggy feature and will be removed,
5304 * (pic16_popGet): set register instance field in AOP_CRY,
5305 * (pic16_outBitC): fixed for results in size greater than 1,
5306 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5307 * (pic16_storeForReturn): optimized return of 0,
5308 * (genCmp): experimental code for new genCmp which uses PIC18's
5309 special compare&skip instructions. Initial tests fail some times
5310 with variables grater than 1 byte in size, so new code is disabled,
5311 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5313 * (genCast): began a fix to optimize the casting of a bit to another
5314 bit, now assigning a bitfield to another bitfield will fail, sorry,
5315 * src/pic16/main.c: disabled the use of lr-support feature,
5316 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5319 bits with offset (case PO_GPR_BIT),
5320 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5322 * (isBankInstruction): modified to return 0 for no banking instruction,
5323 and 1 for banking instruction,
5324 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5325 caused stop processing pCodes after a inline assembly block,
5326 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5327 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5328 registers when it shouldn't,
5329 * src/pic16/ralloc.c (allocReg): add preliminary support for
5330 supporting a limited set of temporary registers,
5332 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5334 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5335 genDataPointerSet): ensure assignments always copy in MSB to LSB
5337 (loadRegFromAop): recognize CLRH optimization,
5338 (genFunction): optimize RECEIVE iCodes in reentrant functions
5340 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5342 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8269 * src/pic/glue (pic14emitRegularMap),
8270 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
8272 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
8274 * src/pic/pcode.c (PCodeID): commented out left over debug code
8276 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
8278 * support/valdiag/tests/overflow.c: added shift tests
8286 * src/pic/pcodepeep.c,
8287 * src/pic/pcoderegs.c,
8289 * src/pic/ralloc.h: applied patch from Slade Rich;
8290 added support for multiple code pages and multiple RAM banks on the
8291 PIC 14 port. The ASM files now no longer simply assume all the
8292 code / RAM are in the same page / bank. This means the linker can
8293 safely allocate code/RAM of separate ASM files to different pages/banks.
8294 * doc/sdccman.lyx: added Slade's tips
8295 * src/mcs51/peeph.def: fixed bug #880768

8304 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
8307 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8308 strtof is not part of C89 and isn't included with Mac OS X.
8310 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8312 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

8330 * src/SDCCicode.c (geniCodeAdd): fixed part of bug #877103
8332 2004-01-16 Klaus Flittner <klaus_flittner AT gmx.de>
8334 * src/ds390/gen.c (aopOp3): fixed the assignment of different dptrs to
8337 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8339 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8340 loaded with the linker search paths (-L arguments) and the libraries
8341 to be linked with the current source (-l arguments). Changes
8342 currently will affect only the pic16 port.
8343 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8344 include path the port specific paths and port specific libraries,
8345 * gplink command now contains the $3 argument,
8346 * src/pic16/device.h,
8347 * src/pic16/device.c,: structure PIC_device is made public and
8348 renamed to PIC16_device, the same for variable Pics which is renamed
8349 to Pics16. Updated all references to them.
8350 * src/pic16/glue.c (pic16glue): corrected bug with code
8351 initialization which bypassed the variable initializations block.
8353 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8354 COMPILE_FLAGS and added the --nostdinc option
8356 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8361 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8363 Documenting changes from previous commits.
8364 * configure.in (version 1.56),
8365 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8366 when generating output files to configure the pic16 library,
8367 but now I've commented it out, since gputils aren't installed in the
8368 SF compile farm, so library won't compile
8370 * device/lib/Makefile.in (version 1.56): initially I've added in
8371 target 'all' the prerequestive 'model-pic16' so it compiled the
8372 pic16 library, but now I've commented it out for the same reasons
8374 * added targets 'model-pic16' and 'objects-pic16' to compile the
8376 * added target 'port-specific-objects-pic16' to handle the
8377 generated libraries and copy them into the build/ directory
8378 * added target 'clean-intermediate-pic16' to clean intermediate
8379 files into pic16 directory
8380 * in target 'installdirs' added line to create directory pic16 in
8381 the installation path
8383 * device/include/Makefile.in (version 1.11): in target 'install'
8384 added lines to copy all header files to installation path,
8385 * in target 'installdirs' added line create directory for pic16
8386 headers in the installation path

8401 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8402 option so that it actually works. Made it specific to the z80, since
8403 the gbz80 doesn't have these kinds of I/O ports.
8405 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8407 * device/include/z180.h,

8420 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8422 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8423 changed interrupt vector table generation to only emit declared vectors.

8429 Mainly changes to support compilation of the device libraries
8430 * src/pic16/device.c: stack is allocated via symbol and not
8431 via literal number. The symbol is placed in the corresponding
8432 position of the data ram
8433 * (pic16_dump_section): relocatable and absolute uninitialized
8434 data are now emitted in sorted order to reduce section naming,
8435 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8436 weren't marked as being in the access bank,
8438 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8440 Added portion of GNU PIC Library under the directory
8441 device/include/pic16 and device/lib/pic16. These files
8442 contain the declarations of SFRs for the PIC18Fxx2 devices.
8443 The directory is initialized via configure from toplevel.
8445 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8447 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8459 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8461 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8462 in simpler and even better code

8473 all over. Telling LaTeX to be less strict with word spacing
8474 to better keep the right margin. Changed some notes about
8475 maintainance of the ports in section 3.2.1 - is it OK like this?
8477 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8515 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8517 * src/pic16/peeph.def: all peepholes with movff are commented out,
8518 because there is a problem in the pcode peep optimizer,
8519 * src/pic16/ralloc.c: the register allocator can now reuse local

8658 Bug reported from Jesus Calvino-Fraga
8660 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8662 * sdcc.spec: updated
8663 * device/include/Makefile.in: don't install CVS directories

8668 * src/ds390/gen.c (genRightShift): fixed bug #870788
8669 * src/SDCCast.c (decorateType): fixed bug #870781
8671 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8673 PIC16 port related changes:
8674 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8675 added variable stackPos,
8677 * gen.c: genCall, assignResultValue: added support for
8678 pushing/retrieving function parameters to/from stack,
8679 genFunction,genEndFunction: setup stack frame for the
8681 genAddrOf: will be changed according to bug 863624
8683 * added files genutils.c and genutils.h which contain gen*
8684 debugged and optimised functions extracted from gen.c
8686 * glue.c: added variable 'externs' which holds extern symbols,
8687 pic16emitRegularMap: is modified to properly handle relocatable
8688 symbols under the new scheme,
8689 pic16createInterruptVect: is modified
8690 pic16printPublics: is modified to emit 'global' assembler directives,
8691 added pic16_printExterns to print extern symbols,
8692 pic16glue: initializes stack/frame pointer in the beginning of
8693 the assembly output. Temporary hack, will be corrected later,
8694 because gplink yet does not support stack and SDCC does not
8695 yet support a type of crt0.o object to create the final binary.
8697 * Removed many lines that contain 8051 legacy code.
8698 * The code is finally placed under a 'code' directive.
8699 * Added port specific options.
8701 * _process_pragma: simplified since now we do not need *special*
8702 include file to define SFR registers. But a separate header
8703 will be needed. This will be developed later.
8704 * _pic16_parseOptions: added, parses port specific options:
8705 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8706 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8707 --preplace-udata-with=
8709 * _pic16_setDefaultOptions: modified to initialize section names,
8710 but hack is temporarly out of order since it needs improvement.
8711 * _pic16_genAssemblerPreamble: configuration words are emitted by
8712 their address instead of their name. This part is incomplete and
8713 supports only the 18Fxx2 devices. Other devices will emit an error
8714 during assembly since they do not contain the same set of config
8716 * _pic16_genIVT: is modified,
8718 * pcode.c: added definitions for some hardware registers that are needed
8720 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8721 All PCI entries are updated. Now LFSR is supported.
8722 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8723 * added pic16_newpCodeOpLit2 to support instructions with
8724 two literal arguments
8725 * pic16_pCode2str: corrected code that emits assembler instructions
8726 with two literal operands and those that have an access bit modifier
8727 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8728 this fixes a bug which caused some labels to be lost, when an
8729 assembler directive was added, i.e. banksel,
8730 * pic16_FixRegisterBanking: improved logic that causes the insertion
8732 * InlineFunction: functions that are called once, are not any more
8733 inlined. This can be a port option in the future,
8735 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8737 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8738 hold the corresponding uninitialized symbols,
8739 * pic16_allocProcessorRegister: registers have explicit marked the
8741 * pic16_allocInternalRegister: registers are explicit marked as
8743 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8744 processing list, so bit registers were lost,
8747 * ralloc.h: added field 'accessBank' and original symbol operand
8748 in register definition,
8749 * removed the field isMapped from register definition,
8751 ** Several functions have been removed from various sources:
8752 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8753 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8754 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8755 pic16_assignRelocatableRegisters
8757 ** others have been introduced:
8758 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8759 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8761 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8763 * support/scripts/inc2h.pl: changed definition of BIT_AT
8764 to emit 'sbit at' instead of 'bit at'. This was a request.
8766 PIC16 port related preliminary changes:
8767 * gen.c: prefixed function popRegFromString with
8768 pic16_ and all references to it corrected
8769 * pcode.c: all pic16_pc_* hardware registers prefixed
8770 with underscore (_),
8771 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8772 * ralloc.c: newReg(): when register is REG_SFR then
8773 set address to rIdx,
8774 pic16_allocProcessorRegister(): marks register wasUsed=0
8775 pic16_writeUsedRegs(): added a call to assign processor
8776 registers via pic16_assignFixedRegisters
8778 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8780 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8781 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8782 variables in unused register banks. Also the SSEG is placed
8783 wherever there is enough space for it, and IDATA can be anywhere
8784 in internal RAM. For now compile using -Wl-Y[stack_size].
8785 The mem file is different for this option as well, since it
8786 makes no sense of talking about DSEG lenght.
8788 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8790 * src/SDCClrange.c: fixed bug 869095 that caused segfault

9035 * src/SDCCast.c (decorateType): disabled a transformation I added in
9036 revision 1.188 (access to fields of a structure at an absolute address);
9037 it breaks with bitfields, extern declarations, and gcse analysis.
9038 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9039 could be assigned through a pointer, so don't complain.

9763 reported in bug #800609
9765 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
9767 * Top header beautifications in src/pic16 directory:
9768 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
9769 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9770 pcoderegs.h, ralloc.c, ralloc.h
9771 * main.c: added top header and GPL license notice
9772 * pcode.c: fixed the if-conditional warning
9774 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
9776 * device/lib/_mullong.c: replaced int by short for gcc
9778 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9780 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
9781 and JUMPTABLE iCodes properly now (worked by accident before)
9782 * src/mcs51/gen.c (leftRightUseAcc),
9783 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9784 iCode properly now. Use getSize instead of nRegs since a & b
9785 aren't part of the nRegs tally.
9787 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9789 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9790 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
9791 before instructions that use the _STATUS register
9793 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9795 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9796 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9797 fetching of the pointer
9798 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9799 copied from genNearPointerSet()
9800 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9801 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9802 If they pop r0/r1 they must be called in the opposite order than aopOp().
9803 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9804 (resp. --stack-auto), prepared for --xstack
9806 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9810 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9812 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9813 these ports have their own __sdcc_external_start()
9815 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9817 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9818 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9819 type for bits was changed. It resulted in bit variables becoming
9820 global, which is not permitted in PIC 14 assembly output.
9822 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9824 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9826 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9828 Z80 and MCS51 linkers complaint if a public symbol is defined
9829 in more than one library module:
9833 * as/mcs51/Makefile.in
9835 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9837 A few small changes that speed up the peephole optimizer.
9841 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9843 Try to make the peephole optimizer smarter by maintaining
9844 an association between the assembly source code and the
9845 iCodes that originated them. Put this information to use
9846 with a new peephole rule condition "notVolatile" so that
9847 the rules can be aggressive yet still safe.
9852 * src/mcs51/peeph.def
9854 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9858 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9859 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9860 if the left or right operand symbols have the accuse flag set.
9862 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9864 Changed the type of the result of the ! (NOT) operator to char;
9865 previously it returned the same type as the source. This allows
9866 us to eliminate all the genFloatNot functions (all of its target
9867 implementations were very buggy) since !float can use the same
9870 * src/SDCCicode.c (ast2iCode): ! returns char
9871 * src/mcs51/gen.c (genNot, genNotFloat),
9872 * src/ds390/gen.c (genNot, genNotFloat),
9873 * src/z80/gen.c (genNot, genNotFloat),
9874 * src/pic/gen.c (genNot, genNotFloat),
9875 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9877 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9879 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9880 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9881 during interrupts. Ensure WSAVE is located at a shared bank address.
9882 2. Fixed page selection in some places
9883 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9884 the registers name strings.
9885 4. Fixed "signed / unsigned compare" compiler warnings.
9886 5. The PIC port manages its own allocation of the general purpose
9887 registers, but makes no attempt to reuse them. As a result when
9888 compiling it soon runs out of general purpose registers. Some
9889 additional code was added to the files pcode.c and device.c to walk
9890 through the function call tree and rename the registers so that they
9900 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9901 genPlus() & genMinus() when the result is the same as left or right

9907 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9909 Made bitfield a distinct type from bit so that bitfields
9910 convert as per ANSI C and bits retain their traditional
9911 boolean style behaviour. Implemented bitfield support in
9919 * src/ds390/gen.c: bit v bitfield split
9920 * src/z80/gen.c: New support for bitfields
9921 * support/regression/tests/bitfields.c: reenabled z80,
9924 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9926 Rules 246.x, 247.x relate to bitfields, the others speed up
9927 access to xdata mapped I/O devices.
9929 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9931 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9933 Cleaned up genPackBits and genUnpackBits and added two helper
9934 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9935 for literal assignments in genPackBits (thanks to Frieder for
9941 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9943 Fixed bug #748310 (pointer to function type mishandled when the
9944 function name is omitted). Also fixed a SIGSEGV when a function
9945 attribute (reentrant, etc) is used on a non-function or on a
9946 function but misplaced before the parameter list.
9948 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9950 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9951 * support/Util/SDCCerr.h,
9952 * support/Util/SDCCerr.c: Added func attr misuse error msg
9954 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9956 Fixed bug #787649 by anonymous
9957 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9973 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9975 Made the constant following the "interrupt" keyword optional. If
9976 omitted, the function will not automatically be given an entry
9977 in the interrupt vector table (similar to #pragma NOIV, but
9978 less syntacticly kludgy). The interrupt number is also now
9979 range checked. Also fixed a bug in the high order bit example
9986 * support/Util/SDCCerr.c
9987 * support/Util/SDCCerr.h
9990 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9992 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9993 * src/SDCCicode.c (operandOperation): rewritten some ops
9994 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9995 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9997 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9998 be re-activated by defining REDUCE_LITERALS)
9999 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10000 unsigned, but are signed by default
10001 * src/SDCCval.c (constVal): rearranged
10002 * src/SDCCval.c (valMod): preliminary fix
10003 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10043 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10044 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10045 constants are unsigned; added recognition of "u" flag for unsigned
10046 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10047 * src/SDCCval.c (valDiv, valMod): fixed signdness

10456 the regression tests I'm not brave enough to enable 245.b, 245.c
10457 * doc/sdccman.lyx: added latex preamble for hyperref package.
10458 Using pdflatex this will give you a hyperlinked pdf file with

10508 * src/SDCCmain.c: linkOptions is changed to set *,
10509 added if/endif conditional macros to remove options help
10510 messages from optionsTable when a port is not configured, added
10511 support for the PIc16 port in the ports table, when executing
10512 the compiler with no port specified on command line, a default
10513 port is selected with the new macro DEFAULT_PORT which is
10514 defined in port.h, in setDefaultOptions() linkOptions is removed
10515 from initialization assignment, since now it is a set,
10516 parseCmdLine uses setParseWithComma for linkOptions, in
10517 linkEdit() linkOptions are accessed with new function indexSet()
10518 which returns the i'th item of a set variable. See SDCCset.c, in
10519 linkEdit() when calling buildCmdLine(), added linkOptions as
10520 last argument. Now users can pass arguments to gplink via the
10521 -Wl option, main() uses pic16glue() to glue up pic16 programs
10522 * src/SDCCpeeph.c: various changes to support pic16

10533 * src/pic16/glue.c: commented out some error producing lines
10534 * src/pic16/main.c: __config directives are commented out to stop
10535 gpasm complaining and test the linkage with gplink, _linkCmd and
10536 _asmCmd changed to be more gplink and gpasm friendly
10537 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10538 produced an error when parsed, peep rule 12 is added to utilize
10539 movff, but it is commented out since the pCode does not support
10540 yet a command with 2 address arguments
10542 2003-05-18 <johan AT balder>
10544 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11599 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11600 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11602 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11603 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11605 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11607 * in /sdcc/as/mcs51/ changed these files in order to create an
11608 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11609 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11610 following files to include the previous two files: aslink.dsp,
11611 Makefile.aslink, Makefile.bcc, and Makefile.in.
11613 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11614 .adb instead of .cdb
11616 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11618 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11619 value from option --iram-size.
11621 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11623 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11626 2002-09-18 <wiml AT hhhh.org>
11628 * SDCClrange.h: exposed setFromRange() and setToRange()
11629 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11630 packRegsForAccUse() (bug 542397)
11631 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11632 multiple times and emitting the fetch operations more than once
11633 added aopGetUsesAcc() function to allow binary operators to
11634 fetch their operands in the correct order; made genMinus() emit
11635 compact code for X = LITERAL - Y
11637 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11638 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11639 sprintf() in line 1267.
11641 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11642 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11645 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11646 Changes to aslink (All the changes are marked with 'JCF'):
11648 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11651 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11652 area BSEG. Also moves, if possible, the DATA area down into the internal
11653 ram so more space is available.
11655 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11658 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11659 not bytes. Function summary() which creates a memory usage summary
11660 file with extension .mem. Reports of overlaping stack and small stack
11661 size. If the space for the stack is less than 16 bytes aslink trows a
11664 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11665 the 8051. Option 'y' for memory summary output file.
11667 Changes to sdcc (All the changes are marked with 'JCF'):
11669 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11671 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11672 overlaying area for it (uses RegBankUsed[4]).
11674 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11675 bank zero as used by default. By default aslink locates the stack
11676 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11677 the creation of the .mem file. Delegates the allocation of data area
11678 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11679 the begining of the stack area to aslink.
11681 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11682 glue() in SDCCglue.c creates an area for it.
11684 2002-09-03 Borut Razem <borut.razem AT siol.net>
11685 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11686 sdcc/src/pic/glue.c:
11687 introduced atexit() handler for teporay files removal in case of
11688 errors, assertions, ...
11690 2002-08-29 Borut Razem <borut.razem AT siol.net>
11691 * sdcc/support/cpp2/auto-host_vc_in.h:
11692 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11693 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11694 Maybe there is a similar problem with BORLANDC? It should be checked!
11696 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11697 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11698 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11699 was not executed, and the compiler (cl) launched a warning:
11700 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11702 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11703 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11705 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11706 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11708 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11709 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11710 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11711 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11712 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11713 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11714 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11715 - added Release configuration in VS projects
11716 - review of compiler an linker options
11717 - VC .exe files are generated in bin_vc directory, not to interfere
11718 with binaries generated from other projects (cygwin, mingw, bcc ...)
11720 * sdcc/src/yacc.dsp: added
11722 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11723 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11724 and insert the version number definitions from .version
11726 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11728 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11729 added - genarate auto-host.h using auto-host_vc_in.h as template
11732 removed from CVS, generated automatically
11734 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11735 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11737 2002-08-11 Borut Razem <borut.razem AT siol.net>
11738 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11740 2002-08-10 Borut Razem <borut.razem AT siol.net>
11741 * src/SDCCmain.c (main):
11742 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11743 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11744 The consequence was that some temporary files were not removed.
11747 unification of code in functions tempfilename() and tempfile():
11748 function tempnam() is defined in Visual Studio 6.0 and .NET
11750 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11752 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11753 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11754 - removed compiler command line option /WX: Treats all warnings as errors
11755 - update a list of source files, included into the project
11757 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11758 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11759 changed project type to Generic Project so that can be correcly converted to VS.NET project
11761 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11763 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11765 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11767 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11768 added return 0 statements after assert() to make compiler happy
11770 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11771 added newline in the def file to keep MSC compiler satisfied
11773 * sdcc/src/z80/gen.c:
11774 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11775 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11776 - solved MSC error in function aopDump()
11778 * sdcc_vc.h: define PREFIX as "\\sdcc"
11780 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11781 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11783 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11784 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11785 - Rewrote the register banking algorithm.
11786 - Added pCode live-range analysis to registers (for now, only non-used and
11787 singly-used registers optimized away)
11789 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11791 * 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.

11816 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11818 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11820 2002-03-28 Johan Knol <johan AT balder>
11822 * src/SDCCval.c: fixed bug #532436
11824 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11826 Added "char *Processor" field to the port structure.
11829 Added -p option. Allows port dependent processor to be specified.
11832 Initialized the new field char *Processor field to NULL in all ports
11835 Compiler generated registers for interrupt context saving
11836 were not getting allocated.
11838 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11841 Fixed left shift. Will promote the left side of a left shift
11842 if a) left shifting more than size of operand or b) when assigned
11843 to something size > size of left side
11845 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11847 tons of changes. Register allocation has been

11849 analysis is restructured. ...
11851 * src/pic/device.h:
11854 * src/pic/device.c:
11855 Added. device.c is a PIC port hack to accomodate variations
11858 2002-03-13 Michael Hope <michaelh AT vroom>
11860 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11862 2002-03-04 johanknol <johanknol AT manik>
11864 * /src/SDCCval.c: fixed
11866 const unsigned char arr[][2] = { { 0, 1 } };

11953 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11955 * sdcc/src/SDCCloop.c:
11956 Previous fix was not good. basic blocks that have "break" or "return" are
11957 not really partof a loop , but live ranges used in these blocks should
11958 be live thru the entire loop, so set partOfLoop but don't add them to
11961 2002-02-21 <johan AT FRIJA>
11963 * src/SDCCcse.c: fixed bug #514308
11965 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11968 Fixed BUG #519583. If a conditional block ended in a return/break
