1557 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1559 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1560 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1562 One basic decision: e.g. src/clean.mk includes further files. In order
1563 to make this work there are two solutions:
1564 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1565 run configure on them. This way they can use
1566 'include $(srcdir)/port-clean.mk'
1567 - always include clean.mk by the Makefile at the same level. To avoid
1568 that `make clean` tries to include and build Makefile.dep the
1569 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1570 implemented, because now even `make uninstall` doesn't create
1571 Makefile.in. clean.mk could be eliminated by pasting it in
1574 * debugger/mcs51/Makefile.in: build own objects from library sources
1575 (SLIB, SDCC) in current directory
1577 * configure, configure.in: renamed --disable-device-lib-build in
1578 --disable-device-lib; added --enable-doc, the required tools are
1579 searched by configure; added result message; the toolchain for the
1580 belonging ports are now only built, if the port is enabled.
1582 * support/regression/*: all output is written in directory gen, because
1583 the fwk and ports directories don't livet in the build tree using vpath
1585 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1586 --disable-device-lib, added --enable-doc, added section VPATH
1588 * sim/ucsim/configure.in,
1589 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1590 z80 are enabled by default
1592 2006-04-24 Raphael Neider <rneider AT web.de>
1594 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1595 to config word, "pic14_"-prefixed some extern functions
1596 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1597 config word has been found
1598 * src/pic/device.h: added prototypes
1599 * src/pic/pcode.c: added "pic14_"-prefix where needed
1600 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1602 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1617 (pCodeRegOptimizeRegUsage): fixed typo in comment

1849 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1851 * src/SDCCpeeph.c (operandsLiteral): new, added,

1863 implemented patch 1120823 Thanks to Willy De la Court (normal
1864 interrupts need an interrupt number now if they are made critical),
1865 and enabled nesting of critical functions though not for gbz80
1866 (genCritical, genEndCritical): added functions
1867 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1868 * src/z80/mappings.i: added "ei" to all mappings

1880 the left operand is shorter than the result (c* = lit-c* + int),
1882 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1885 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1887 * src/.version: increased version number to 2.5.5
1888 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1889 linking is done manually in pic16 port's _linkEdit,
1890 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1891 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1892 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1893 allocate asmop as AOP_ACC,
1894 (aopForRemat): added parameter 'bool result' in function declaration,
1895 (pic16_aopGet): return AOP_ACC when accessing WREG,
1896 (pic16_popGetTempReg): minor modification,

1905 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1907 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1908 call to allocReg, not by manually allocating a new one,
1909 (pic16_assignRegisters): now before going through the register
1910 allocating functions mark all registers as free. This eliminates some
1911 side effects resulting from peephole parser done earlier in the backbone
1913 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1915 * src/SDCCicode.c (geniCodeLogic),

1935 (aopForSym, aopOp): increment asmop.allocated if reused,
1936 (freeAsmop): decrement asmop.allocated and check for zero instead of
1938 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1939 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1940 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1973 the number of the local variables used by the specified function, added
1974 'xinst' for initial support for Extended Instruction Support,
1975 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1976 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1977 port->fun_prefix anymore (may change later),
1978 (genFunction, genEndFunction): do not store/restore local registers for
1979 _main (this should take care the --main-return command line option in
1981 (genOr): removed some legacy pic-port instructions,
1982 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1983 performing operations with SFR's causes data to be written more than
1984 once to each SFR. Perhaps SFRs should be handled in special cases...
1985 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1987 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1988 into account for stack starting position,

1990 --extended or -y for Extended Instruction Support,
1991 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1992 (deassignLRs): *** perhaps the most important change, old 'for' code
1993 (commented out for reference), didn't account for some registers which
1994 were left marked 'not free' after a pointer operation. The change
1995 reduces register usage a lot in some cases

4314 * src/SDCCdflow.c (computeDataFlow),
4316 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
4318 * src/SDCCcflow.c (*),
4320 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4321 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4322 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4323 immedDom() returning wrong block; probably fixes bug #1160833)
4325 2005-03-20 Borut Razem <borut.razem AT siol.net>
4327 * support/scripts/inc2h.pl: WIN32 port
4329 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4331 * device/lib/makefile.in: added abs.c and labs.c
4333 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4335 * device/include/stdint.h: added
4336 * device/lib/abs.c: added
4337 * device/lib/labs.c: added
4338 * device/include/stdlib.h: added abs() and labs() prototypes
4339 * device/lib/libsdcc.lib: added abs and labs
4340 * device/include/float.h,
4341 * device/lib/_fsmul.c,
4342 * device/lib/printf_fast.c,
4343 * device/lib/printf_tiny.c: updated comments
4345 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4347 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4350 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4352 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4353 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4355 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4357 * device/lib/printf_large.c: removed inline assembly for portability and
4358 readability. Use printf_fast if speed or size are more important.
4359 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4360 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4362 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4364 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4365 prevent compiler warning
4367 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4369 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4370 moved to level 0 and declared as static. Also they are explicit
4371 placed in access bank. This was necessery because some times they
4372 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4373 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4374 optimizations. Currently only compare to unsigned char is implemented,
4375 * src/pic16/gen.c: added fReturnIdx array,
4376 * (struct resolvedIfx) is moved to gen.h and made public,
4377 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4378 * (aopForSym): added an optimization to directly store in stack of
4379 the operand of a SEND iCode,
4380 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4381 but as registers instead (AOP_REG) using the fReturnIdx array,
4382 * (pic16_freeAsmop): remove the freed register from the
4383 _G.sregsAlloc field,
4384 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4385 a compare of 'WREG',
4386 * (pic16_popGetTempRegCond): changed function prototype, now
4387 function takes also a bitVector argument v which holds the current
4388 set of registers that are allocated for stack access by aopForSym,
4389 registers allocated in aopForSym for accessing stack symbols are not
4390 any more part of the functions usedRegs field,
4391 * (genCall): some times aopOp is called for a stack variable to be
4392 send, aopForSym might perform the push, if this is true make sure
4393 that genCall doesn't push the variable twice by testing _G.resDirect,
4394 * (genFunction): changed testing for unspecified interrupt number
4395 from 256 to INTNO_UNSPEC,
4396 * modified selection scheme of frame pointer generation. Previously
4397 if function did use local registers a frame pointer was generated,
4398 now a frame pointer is generated only if function has arguments
4399 (that need PLUSW2 register access), or has stack arguments, or the
4400 compiler is not instructed to omit the frame pointer,
4401 * (genEndFunction): before restoring local registers that were saved
4402 in the function preamble, also restore the registers that *might*
4403 have been allocated for stack access,
4404 * (genRet): removed some old comments,
4405 * (genCmp, the active (RN's) version): added a call to the
4406 pic16_genCmp_special function to perform the compare with a more
4407 robust and optimized way,
4408 * (genInline): a feature has been added in inline code generation,
4409 which allows a wildcard variable substitution when writing inline
4410 assembly. Code is incomplete and experimental therefore undocumented,
4411 * (genCast): changed order of aopOp for result and right to allow
4412 aopForSym to directly load the result if possible,
4413 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4414 perform an optimized compare on some selected special occasions,
4415 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4416 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4417 generate an IVT any more,
4418 * src/pic16/main.c (pic16_optionsTable): added command line option
4420 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4421 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4423 * src/pic16/NOTES: Raphael Neider added in list of active developers
4424 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4425 jumptable_end to prevent bug #,
4426 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4427 inCond and outCond fields,
4428 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4429 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4430 turn off register spilling,
4431 * (packRegsForOneUse): synced with other ports' versions although it
4432 is not used currently,
4433 * (pic16_packRegisters): added an optimization while reading
4434 structure bitfields, some registers may be saved (malloc code is
4435 decreased by 80 bytes)
4437 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4439 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4440 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4441 this can be optimized more?
4443 2005-03-10 Raphael Neider <rneider AT web.de>
4445 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4446 genNearPointerGet): (hopefully) fixed access to bitfields via
4447 pointers (p->bitN = x; and x = p->bitN; failed)
4449 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4492 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4493 to keep the correct label reference count when adding/removing references
4494 to labels. A peephole file using this is appended to patch #1144962.

4637 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4638 this might fix SIGSEGVs on MinGW...

4727 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4728 used uninitialized in some cases)

4730 copy the third byte from the int -- now assumes 0x80 (data memory)
4731 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4732 operands (genAddLit expects the iCode's operands to swapped as
4733 well), fixed leftover bytes (crashed for short left operands)

5082 generated for switch statements. For now you need to set the
5083 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5084 Now 4 algorithms for mcs51 jumptable generation are used:
5085 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5117 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5119 * added libc directory. The current version of LibC contains string
5120 functions, ctype functions and macros and some functions of the
5121 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5122 be extensively tested in the future. Standard disclaimer here.
5123 Library is not automatically build yet. But one can build it by
5124 invoking 'make' inside the libc directory.

5135 * (pic16_storeForReturn): optimized return of 0,
5136 * (genCmp): experimental code for new genCmp which uses PIC18's
5137 special compare&skip instructions. Initial tests fail some times
5138 with variables grater than 1 byte in size, so new code is disabled,
5139 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5141 * (genCast): began a fix to optimize the casting of a bit to another
5142 bit, now assigning a bitfield to another bitfield will fail, sorry,

5150 * (isBankInstruction): modified to return 0 for no banking instruction,
5151 and 1 for banking instruction,
5152 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5153 caused stop processing pCodes after a inline assembly block,
5154 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5155 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5156 registers when it shouldn't,
5157 * src/pic16/ralloc.c (allocReg): add preliminary support for
5158 supporting a limited set of temporary registers,
5160 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5162 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5163 genDataPointerSet): ensure assignments always copy in MSB to LSB
5165 (loadRegFromAop): recognize CLRH optimization,
5166 (genFunction): optimize RECEIVE iCodes in reentrant functions
5168 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5170 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5179 * device/lib/_gptrget.c (_gptrget),
5180 * device/lib/_gptrgetc.c (_gptrgetc),

8165 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8167 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8168 loaded with the linker search paths (-L arguments) and the libraries
8169 to be linked with the current source (-l arguments). Changes
8170 currently will affect only the pic16 port.
8171 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8172 include path the port specific paths and port specific libraries,
8173 * gplink command now contains the $3 argument,
8174 * src/pic16/device.h,
8175 * src/pic16/device.c,: structure PIC_device is made public and
8176 renamed to PIC16_device, the same for variable Pics which is renamed

8191 Documenting changes from previous commits.
8192 * configure.in (version 1.56),
8193 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8194 when generating output files to configure the pic16 library,
8195 but now I've commented it out, since gputils aren't installed in the
8196 SF compile farm, so library won't compile
8198 * device/lib/Makefile.in (version 1.56): initially I've added in
8199 target 'all' the prerequestive 'model-pic16' so it compiled the
8200 pic16 library, but now I've commented it out for the same reasons
8202 * added targets 'model-pic16' and 'objects-pic16' to compile the
8204 * added target 'port-specific-objects-pic16' to handle the
8205 generated libraries and copy them into the build/ directory
8206 * added target 'clean-intermediate-pic16' to clean intermediate
8207 files into pic16 directory
8208 * in target 'installdirs' added line to create directory pic16 in
8209 the installation path

8212 added lines to copy all header files to installation path,
8213 * in target 'installdirs' added line create directory for pic16
8214 headers in the installation path

8230 option so that it actually works. Made it specific to the z80, since
8231 the gbz80 doesn't have these kinds of I/O ports.
8233 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8235 * device/include/z180.h,

8259 via literal number. The symbol is placed in the corresponding
8260 position of the data ram
8261 * (pic16_dump_section): relocatable and absolute uninitialized
8262 data are now emitted in sorted order to reduce section naming,
8263 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8264 weren't marked as being in the access bank,
8266 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8268 Added portion of GNU PIC Library under the directory
8269 device/include/pic16 and device/lib/pic16. These files
8270 contain the declarations of SFRs for the PIC18Fxx2 devices.
8271 The directory is initialized via configure from toplevel.

8300 * doc/sdccman.lyx: Moved and added some sections, small changes
8301 all over. Telling LaTeX to be less strict with word spacing
8302 to better keep the right margin. Changed some notes about
8303 maintainance of the ports in section 3.2.1 - is it OK like this?
8305 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8307 SDCC source changes:
8308 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8342 UPPER for immediate operands,
8343 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8345 * src/pic16/peeph.def: all peepholes with movff are commented out,
8346 because there is a problem in the pcode peep optimizer,
8347 * src/pic16/ralloc.c: the register allocator can now reuse local

8440 include information about variables allocated to the overlay
8443 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8445 * as/mcs51/lkmain.c: Help about -Y option

8457 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8459 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8460 (default behaviour).
8462 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8464 A python script to validate compiler diagnostic messages. It can be
8465 used to verify that sdcc complains about bad c source code and
8466 gives a good location of the error.
8467 * support/valdiag/Makefile,
8468 * support/valdiag/valdiag.py,
8469 * support/valdiag/tests/*

8486 Bug reported from Jesus Calvino-Fraga
8488 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8490 * sdcc.spec: updated
8491 * device/include/Makefile.in: don't install CVS directories
8492 * device/lib/Makefile.in: added removal of CVS directories after install
8493 * doc/Makefile: fixed install, added local_icons
8494 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8495 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8496 * src/ds390/gen.c (genRightShift): fixed bug #870788
8497 * src/SDCCast.c (decorateType): fixed bug #870781
8499 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8501 PIC16 port related changes:
8502 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8503 added variable stackPos,
8505 * gen.c: genCall, assignResultValue: added support for
8506 pushing/retrieving function parameters to/from stack,
8507 genFunction,genEndFunction: setup stack frame for the
8509 genAddrOf: will be changed according to bug 863624
8511 * added files genutils.c and genutils.h which contain gen*
8512 debugged and optimised functions extracted from gen.c
8514 * glue.c: added variable 'externs' which holds extern symbols,
8515 pic16emitRegularMap: is modified to properly handle relocatable
8516 symbols under the new scheme,
8517 pic16createInterruptVect: is modified
8518 pic16printPublics: is modified to emit 'global' assembler directives,
8519 added pic16_printExterns to print extern symbols,
8520 pic16glue: initializes stack/frame pointer in the beginning of
8521 the assembly output. Temporary hack, will be corrected later,
8522 because gplink yet does not support stack and SDCC does not
8523 yet support a type of crt0.o object to create the final binary.
8525 * Removed many lines that contain 8051 legacy code.
8526 * The code is finally placed under a 'code' directive.
8527 * Added port specific options.
8529 * _process_pragma: simplified since now we do not need *special*
8530 include file to define SFR registers. But a separate header
8531 will be needed. This will be developed later.
8532 * _pic16_parseOptions: added, parses port specific options:
8533 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8534 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8535 --preplace-udata-with=
8537 * _pic16_setDefaultOptions: modified to initialize section names,
8538 but hack is temporarly out of order since it needs improvement.
8539 * _pic16_genAssemblerPreamble: configuration words are emitted by
8540 their address instead of their name. This part is incomplete and
8541 supports only the 18Fxx2 devices. Other devices will emit an error
8542 during assembly since they do not contain the same set of config
8544 * _pic16_genIVT: is modified,
8546 * pcode.c: added definitions for some hardware registers that are needed
8548 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8549 All PCI entries are updated. Now LFSR is supported.
8550 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8551 * added pic16_newpCodeOpLit2 to support instructions with
8552 two literal arguments
8553 * pic16_pCode2str: corrected code that emits assembler instructions
8554 with two literal operands and those that have an access bit modifier
8555 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8556 this fixes a bug which caused some labels to be lost, when an
8557 assembler directive was added, i.e. banksel,
8558 * pic16_FixRegisterBanking: improved logic that causes the insertion
8560 * InlineFunction: functions that are called once, are not any more
8561 inlined. This can be a port option in the future,
8563 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8565 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8566 hold the corresponding uninitialized symbols,
8567 * pic16_allocProcessorRegister: registers have explicit marked the
8569 * pic16_allocInternalRegister: registers are explicit marked as
8571 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8572 processing list, so bit registers were lost,
8575 * ralloc.h: added field 'accessBank' and original symbol operand
8576 in register definition,
8577 * removed the field isMapped from register definition,
8579 ** Several functions have been removed from various sources:
8580 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8581 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8582 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8583 pic16_assignRelocatableRegisters
8585 ** others have been introduced:
8586 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8587 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8589 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8591 * support/scripts/inc2h.pl: changed definition of BIT_AT
8592 to emit 'sbit at' instead of 'bit at'. This was a request.
8594 PIC16 port related preliminary changes:
8595 * gen.c: prefixed function popRegFromString with
8596 pic16_ and all references to it corrected
8597 * pcode.c: all pic16_pc_* hardware registers prefixed
8598 with underscore (_),
8599 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8600 * ralloc.c: newReg(): when register is REG_SFR then
8601 set address to rIdx,
8602 pic16_allocProcessorRegister(): marks register wasUsed=0
8603 pic16_writeUsedRegs(): added a call to assign processor
8604 registers via pic16_assignFixedRegisters
8606 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8608 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8609 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8610 variables in unused register banks. Also the SSEG is placed
8611 wherever there is enough space for it, and IDATA can be anywhere
8612 in internal RAM. For now compile using -Wl-Y[stack_size].
8613 The mem file is different for this option as well, since it
8614 makes no sense of talking about DSEG lenght.
8616 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8618 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8619 in certain cases, e.g. when ROM assignment, patch provided
8620 from Albert den Haan.
8622 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8765 * src/mcs51/peephole.def,
8766 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8767 (allows non-interrupt and interrupt code to safely compete for a resource

9645 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9646 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9647 type for bits was changed. It resulted in bit variables becoming

9665 A few small changes that speed up the peephole optimizer.
9669 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9671 Try to make the peephole optimizer smarter by maintaining
9672 an association between the assembly source code and the
9673 iCodes that originated them. Put this information to use
9674 with a new peephole rule condition "notVolatile" so that
9675 the rules can be aggressive yet still safe.
9680 * src/mcs51/peeph.def
9682 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9686 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9687 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9688 if the left or right operand symbols have the accuse flag set.
9690 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9692 Changed the type of the result of the ! (NOT) operator to char;
9693 previously it returned the same type as the source. This allows
9694 us to eliminate all the genFloatNot functions (all of its target
9695 implementations were very buggy) since !float can use the same
9698 * src/SDCCicode.c (ast2iCode): ! returns char

9707 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9708 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9709 during interrupts. Ensure WSAVE is located at a shared bank address.
9710 2. Fixed page selection in some places
9711 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9712 the registers name strings.
9713 4. Fixed "signed / unsigned compare" compiler warnings.
9714 5. The PIC port manages its own allocation of the general purpose
9715 registers, but makes no attempt to reuse them. As a result when
9716 compiling it soon runs out of general purpose registers. Some
9717 additional code was added to the files pcode.c and device.c to walk
9718 through the function call tree and rename the registers so that they
9728 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9729 genPlus() & genMinus() when the result is the same as left or right

9735 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9737 Made bitfield a distinct type from bit so that bitfields
9738 convert as per ANSI C and bits retain their traditional
9739 boolean style behaviour. Implemented bitfield support in
9747 * src/ds390/gen.c: bit v bitfield split
9748 * src/z80/gen.c: New support for bitfields
9749 * support/regression/tests/bitfields.c: reenabled z80,
9752 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9754 Rules 246.x, 247.x relate to bitfields, the others speed up
9755 access to xdata mapped I/O devices.
9757 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9759 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9761 Cleaned up genPackBits and genUnpackBits and added two helper

9771 Fixed bug #748310 (pointer to function type mishandled when the
9772 function name is omitted). Also fixed a SIGSEGV when a function
9773 attribute (reentrant, etc) is used on a non-function or on a
9774 function but misplaced before the parameter list.

9803 Made the constant following the "interrupt" keyword optional. If
9804 omitted, the function will not automatically be given an entry
9805 in the interrupt vector table (similar to #pragma NOIV, but
9806 less syntacticly kludgy). The interrupt number is also now
9807 range checked. Also fixed a bug in the high order bit example
9814 * support/Util/SDCCerr.c
9815 * support/Util/SDCCerr.h
9818 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9821 * src/SDCCicode.c (operandOperation): rewritten some ops
9822 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9823 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9825 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9826 be re-activated by defining REDUCE_LITERALS)
9827 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9828 unsigned, but are signed by default
9829 * src/SDCCval.c (constVal): rearranged
9830 * src/SDCCval.c (valMod): preliminary fix
9831 * src/SDCCval.c (valCastLiteral): use TYPE_* types
9832 * support/regression/literalop.c: added, work in progress
9834 2003-08-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9874 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9875 * src/SDCCval.c (valDiv, valMod): fixed signdness
9876 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9877 signedness of modulo, left and right shift
9878 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

10283 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10284 the regression tests I'm not brave enough to enable 245.b, 245.c
10285 * doc/sdccman.lyx: added latex preamble for hyperref package.
10286 Using pdflatex this will give you a hyperlinked pdf file with

10337 added if/endif conditional macros to remove options help
10338 messages from optionsTable when a port is not configured, added
10339 support for the PIc16 port in the ports table, when executing
10340 the compiler with no port specified on command line, a default
10341 port is selected with the new macro DEFAULT_PORT which is
10342 defined in port.h, in setDefaultOptions() linkOptions is removed
10343 from initialization assignment, since now it is a set,
10344 parseCmdLine uses setParseWithComma for linkOptions, in
10345 linkEdit() linkOptions are accessed with new function indexSet()
10346 which returns the i'th item of a set variable. See SDCCset.c, in
10347 linkEdit() when calling buildCmdLine(), added linkOptions as
10348 last argument. Now users can pass arguments to gplink via the

11420 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11421 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11427 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11428 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11430 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11431 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11433 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11435 * in /sdcc/as/mcs51/ changed these files in order to create an
11436 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11437 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11438 following files to include the previous two files: aslink.dsp,
11439 Makefile.aslink, Makefile.bcc, and Makefile.in.
11441 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11442 .adb instead of .cdb
11444 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11446 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11447 value from option --iram-size.
11449 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11451 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11454 2002-09-18 <wiml AT hhhh.org>
11456 * SDCClrange.h: exposed setFromRange() and setToRange()
11457 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11458 packRegsForAccUse() (bug 542397)
11459 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11460 multiple times and emitting the fetch operations more than once
11461 added aopGetUsesAcc() function to allow binary operators to
11462 fetch their operands in the correct order; made genMinus() emit
11463 compact code for X = LITERAL - Y
11465 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11466 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11467 sprintf() in line 1267.
11469 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11470 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11473 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11474 Changes to aslink (All the changes are marked with 'JCF'):
11476 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11479 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11480 area BSEG. Also moves, if possible, the DATA area down into the internal
11481 ram so more space is available.
11483 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11486 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11487 not bytes. Function summary() which creates a memory usage summary
11488 file with extension .mem. Reports of overlaping stack and small stack
11489 size. If the space for the stack is less than 16 bytes aslink trows a
11492 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11493 the 8051. Option 'y' for memory summary output file.
11495 Changes to sdcc (All the changes are marked with 'JCF'):
11497 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11499 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11500 overlaying area for it (uses RegBankUsed[4]).
11502 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11503 bank zero as used by default. By default aslink locates the stack
11504 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11505 the creation of the .mem file. Delegates the allocation of data area
11506 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11507 the begining of the stack area to aslink.
11509 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11510 glue() in SDCCglue.c creates an area for it.
11512 2002-09-03 Borut Razem <borut.razem AT siol.net>
11513 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11514 sdcc/src/pic/glue.c:
11515 introduced atexit() handler for teporay files removal in case of
11516 errors, assertions, ...
11518 2002-08-29 Borut Razem <borut.razem AT siol.net>
11519 * sdcc/support/cpp2/auto-host_vc_in.h:
11520 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11521 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11522 Maybe there is a similar problem with BORLANDC? It should be checked!
11524 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11525 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11526 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11527 was not executed, and the compiler (cl) launched a warning:
11528 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11530 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11531 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11533 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11534 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11536 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11537 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11538 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11539 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11540 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11541 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11542 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11543 - added Release configuration in VS projects
11544 - review of compiler an linker options
11545 - VC .exe files are generated in bin_vc directory, not to interfere
11546 with binaries generated from other projects (cygwin, mingw, bcc ...)
11548 * sdcc/src/yacc.dsp: added
11550 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11551 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11552 and insert the version number definitions from .version
11554 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11556 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11557 added - genarate auto-host.h using auto-host_vc_in.h as template
11560 removed from CVS, generated automatically
11562 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11563 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11565 2002-08-11 Borut Razem <borut.razem AT siol.net>
11566 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11568 2002-08-10 Borut Razem <borut.razem AT siol.net>
11569 * src/SDCCmain.c (main):
11570 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11571 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11572 The consequence was that some temporary files were not removed.
11575 unification of code in functions tempfilename() and tempfile():
11576 function tempnam() is defined in Visual Studio 6.0 and .NET
11578 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11580 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11581 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11582 - removed compiler command line option /WX: Treats all warnings as errors
11583 - update a list of source files, included into the project
11585 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11586 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11587 changed project type to Generic Project so that can be correcly converted to VS.NET project
11589 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11591 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11593 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11595 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11596 added return 0 statements after assert() to make compiler happy
11598 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11599 added newline in the def file to keep MSC compiler satisfied
11601 * sdcc/src/z80/gen.c:
11602 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11603 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
