1566 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1568 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1569 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1571 One basic decision: e.g. src/clean.mk includes further files. In order
1572 to make this work there are two solutions:
1573 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1574 run configure on them. This way they can use
1575 'include $(srcdir)/port-clean.mk'
1576 - always include clean.mk by the Makefile at the same level. To avoid
1577 that `make clean` tries to include and build Makefile.dep the
1578 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1579 implemented, because now even `make uninstall` doesn't create
1580 Makefile.in. clean.mk could be eliminated by pasting it in
1583 * debugger/mcs51/Makefile.in: build own objects from library sources
1584 (SLIB, SDCC) in current directory
1586 * configure, configure.in: renamed --disable-device-lib-build in
1587 --disable-device-lib; added --enable-doc, the required tools are
1588 searched by configure; added result message; the toolchain for the
1589 belonging ports are now only built, if the port is enabled.
1591 * support/regression/*: all output is written in directory gen, because
1592 the fwk and ports directories don't livet in the build tree using vpath
1594 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1595 --disable-device-lib, added --enable-doc, added section VPATH
1597 * sim/ucsim/configure.in,
1598 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1599 z80 are enabled by default
1601 2006-04-24 Raphael Neider <rneider AT web.de>
1603 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1604 to config word, "pic14_"-prefixed some extern functions
1605 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1606 config word has been found
1607 * src/pic/device.h: added prototypes
1608 * src/pic/pcode.c: added "pic14_"-prefix where needed
1609 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1611 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1625 fixes #1469504 and #1474602,
1626 (pCodeRegOptimizeRegUsage): fixed typo in comment

1849 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1851 * src/mcs51/gen.c (genCall): fixed bug 1457608
1853 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1858 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1860 * src/SDCCpeeph.c (operandsLiteral): new, added,

1872 implemented patch 1120823 Thanks to Willy De la Court (normal
1873 interrupts need an interrupt number now if they are made critical),
1874 and enabled nesting of critical functions though not for gbz80
1875 (genCritical, genEndCritical): added functions
1876 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1877 * src/z80/mappings.i: added "ei" to all mappings

1882 submitted by the Debian SDCC maintainer Aurelien Jarno:
1883 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1884 archive with gcc 4.1 on mips and wrote the patch"
1886 2006-03-16 Raphael Neider <rneider AT web.de>
1888 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1889 the left operand is shorter than the result (c* = lit-c* + int),
1891 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1894 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1896 * src/.version: increased version number to 2.5.5
1897 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1898 linking is done manually in pic16 port's _linkEdit,
1899 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1900 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1901 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1902 allocate asmop as AOP_ACC,
1903 (aopForRemat): added parameter 'bool result' in function declaration,
1904 (pic16_aopGet): return AOP_ACC when accessing WREG,
1905 (pic16_popGetTempReg): minor modification,
1906 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1907 'pic16_allocWithIdx',

1909 calling function in absolute addresses,
1910 (genAssign): take into account AOP_ACC asmop,
1911 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1914 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1916 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1917 call to allocReg, not by manually allocating a new one,
1918 (pic16_assignRegisters): now before going through the register
1919 allocating functions mark all registers as free. This eliminates some
1920 side effects resulting from peephole parser done earlier in the backbone
1922 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1924 * src/SDCCicode.c (geniCodeLogic),

1944 (aopForSym, aopOp): increment asmop.allocated if reused,
1945 (freeAsmop): decrement asmop.allocated and check for zero instead of
1947 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1948 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1980 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1981 which dumps before the function entry point a data byte which represents
1982 the number of the local variables used by the specified function, added
1983 'xinst' for initial support for Extended Instruction Support,
1984 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1985 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1986 port->fun_prefix anymore (may change later),
1987 (genFunction, genEndFunction): do not store/restore local registers for
1988 _main (this should take care the --main-return command line option in
1990 (genOr): removed some legacy pic-port instructions,
1991 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1992 performing operations with SFR's causes data to be written more than
1993 once to each SFR. Perhaps SFRs should be handled in special cases...
1994 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1996 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1997 into account for stack starting position,

1999 --extended or -y for Extended Instruction Support,
2000 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2001 (deassignLRs): *** perhaps the most important change, old 'for' code
2002 (commented out for reference), didn't account for some registers which
2003 were left marked 'not free' after a pointer operation. The change
2004 reduces register usage a lot in some cases

4329 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4330 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4331 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4332 immedDom() returning wrong block; probably fixes bug #1160833)
4334 2005-03-20 Borut Razem <borut.razem AT siol.net>
4336 * support/scripts/inc2h.pl: WIN32 port
4338 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4340 * device/lib/makefile.in: added abs.c and labs.c
4342 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4344 * device/include/stdint.h: added
4345 * device/lib/abs.c: added
4346 * device/lib/labs.c: added
4347 * device/include/stdlib.h: added abs() and labs() prototypes
4348 * device/lib/libsdcc.lib: added abs and labs
4349 * device/include/float.h,
4350 * device/lib/_fsmul.c,
4351 * device/lib/printf_fast.c,
4352 * device/lib/printf_tiny.c: updated comments
4354 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4356 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4359 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4361 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4362 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4364 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4366 * device/lib/printf_large.c: removed inline assembly for portability and
4367 readability. Use printf_fast if speed or size are more important.
4368 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4369 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4371 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4373 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4374 prevent compiler warning
4376 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4378 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4379 moved to level 0 and declared as static. Also they are explicit
4380 placed in access bank. This was necessery because some times they
4381 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4382 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4383 optimizations. Currently only compare to unsigned char is implemented,
4384 * src/pic16/gen.c: added fReturnIdx array,
4385 * (struct resolvedIfx) is moved to gen.h and made public,
4386 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4387 * (aopForSym): added an optimization to directly store in stack of
4388 the operand of a SEND iCode,
4389 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4390 but as registers instead (AOP_REG) using the fReturnIdx array,
4391 * (pic16_freeAsmop): remove the freed register from the
4392 _G.sregsAlloc field,
4393 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4394 a compare of 'WREG',
4395 * (pic16_popGetTempRegCond): changed function prototype, now
4396 function takes also a bitVector argument v which holds the current
4397 set of registers that are allocated for stack access by aopForSym,
4398 registers allocated in aopForSym for accessing stack symbols are not
4399 any more part of the functions usedRegs field,
4400 * (genCall): some times aopOp is called for a stack variable to be
4401 send, aopForSym might perform the push, if this is true make sure
4402 that genCall doesn't push the variable twice by testing _G.resDirect,
4403 * (genFunction): changed testing for unspecified interrupt number
4404 from 256 to INTNO_UNSPEC,
4405 * modified selection scheme of frame pointer generation. Previously
4406 if function did use local registers a frame pointer was generated,
4407 now a frame pointer is generated only if function has arguments
4408 (that need PLUSW2 register access), or has stack arguments, or the
4409 compiler is not instructed to omit the frame pointer,
4410 * (genEndFunction): before restoring local registers that were saved
4411 in the function preamble, also restore the registers that *might*
4412 have been allocated for stack access,
4413 * (genRet): removed some old comments,
4414 * (genCmp, the active (RN's) version): added a call to the
4415 pic16_genCmp_special function to perform the compare with a more
4416 robust and optimized way,
4417 * (genInline): a feature has been added in inline code generation,
4418 which allows a wildcard variable substitution when writing inline
4419 assembly. Code is incomplete and experimental therefore undocumented,
4420 * (genCast): changed order of aopOp for result and right to allow
4421 aopForSym to directly load the result if possible,
4422 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4423 perform an optimized compare on some selected special occasions,
4424 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4425 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4426 generate an IVT any more,
4427 * src/pic16/main.c (pic16_optionsTable): added command line option
4429 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4430 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4432 * src/pic16/NOTES: Raphael Neider added in list of active developers
4433 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4434 jumptable_end to prevent bug #,
4435 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4436 inCond and outCond fields,
4437 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4438 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4439 turn off register spilling,
4440 * (packRegsForOneUse): synced with other ports' versions although it
4441 is not used currently,
4442 * (pic16_packRegisters): added an optimization while reading
4443 structure bitfields, some registers may be saved (malloc code is
4444 decreased by 80 bytes)
4446 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4448 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4449 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4450 this can be optimized more?
4452 2005-03-10 Raphael Neider <rneider AT web.de>
4454 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4455 genNearPointerGet): (hopefully) fixed access to bitfields via
4456 pointers (p->bitN = x; and x = p->bitN; failed)
4458 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4501 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4502 to keep the correct label reference count when adding/removing references
4503 to labels. A peephole file using this is appended to patch #1144962.

4646 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4647 this might fix SIGSEGVs on MinGW...
4648 * src/SDCCopt.c (killDeadCode): restored original behaviour
4649 (volatile operands might get thrown away though)
4651 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4735 * (genUminus): rewritten to for efficiency
4736 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4737 used uninitialized in some cases)

4739 copy the third byte from the int -- now assumes 0x80 (data memory)
4740 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4741 operands (genAddLit expects the iCode's operands to swapped as
4742 well), fixed leftover bytes (crashed for short left operands)

5092 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5093 Now 4 algorithms for mcs51 jumptable generation are used:
5094 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5128 * added libc directory. The current version of LibC contains string
5129 functions, ctype functions and macros and some functions of the
5130 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5131 be extensively tested in the future. Standard disclaimer here.

5145 * (genCmp): experimental code for new genCmp which uses PIC18's
5146 special compare&skip instructions. Initial tests fail some times
5147 with variables grater than 1 byte in size, so new code is disabled,
5148 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5150 * (genCast): began a fix to optimize the casting of a bit to another
5151 bit, now assigning a bitfield to another bitfield will fail, sorry,

5165 registers when it shouldn't,
5166 * src/pic16/ralloc.c (allocReg): add preliminary support for
5167 supporting a limited set of temporary registers,
5169 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5175 (genFunction): optimize RECEIVE iCodes in reentrant functions
5177 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5179 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8174 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8176 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8177 loaded with the linker search paths (-L arguments) and the libraries
8178 to be linked with the current source (-l arguments). Changes
8179 currently will affect only the pic16 port.
8180 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8181 include path the port specific paths and port specific libraries,
8182 * gplink command now contains the $3 argument,
8183 * src/pic16/device.h,
8184 * src/pic16/device.c,: structure PIC_device is made public and
8185 renamed to PIC16_device, the same for variable Pics which is renamed

8200 Documenting changes from previous commits.
8201 * configure.in (version 1.56),
8202 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8203 when generating output files to configure the pic16 library,
8204 but now I've commented it out, since gputils aren't installed in the
8205 SF compile farm, so library won't compile
8207 * device/lib/Makefile.in (version 1.56): initially I've added in
8208 target 'all' the prerequestive 'model-pic16' so it compiled the
8209 pic16 library, but now I've commented it out for the same reasons
8211 * added targets 'model-pic16' and 'objects-pic16' to compile the
8213 * added target 'port-specific-objects-pic16' to handle the
8214 generated libraries and copy them into the build/ directory
8215 * added target 'clean-intermediate-pic16' to clean intermediate
8216 files into pic16 directory
8217 * in target 'installdirs' added line to create directory pic16 in
8218 the installation path
8220 * device/include/Makefile.in (version 1.11): in target 'install'
8221 added lines to copy all header files to installation path,
8222 * in target 'installdirs' added line create directory for pic16
8223 headers in the installation path

8238 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8239 option so that it actually works. Made it specific to the z80, since
8240 the gbz80 doesn't have these kinds of I/O ports.
8242 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8244 * device/include/z180.h,

8268 via literal number. The symbol is placed in the corresponding
8269 position of the data ram
8270 * (pic16_dump_section): relocatable and absolute uninitialized
8271 data are now emitted in sorted order to reduce section naming,
8272 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8273 weren't marked as being in the access bank,
8275 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8277 Added portion of GNU PIC Library under the directory
8278 device/include/pic16 and device/lib/pic16. These files
8279 contain the declarations of SFRs for the PIC18Fxx2 devices.
8280 The directory is initialized via configure from toplevel.
8282 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8291 2004-01-12 Borut Razem <borut.razem AT siol.net>
8293 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
8294 doc/sdccman.lyx: upper case pragmas are deprecated
8296 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

8309 * doc/sdccman.lyx: Moved and added some sections, small changes
8310 all over. Telling LaTeX to be less strict with word spacing
8311 to better keep the right margin. Changed some notes about
8312 maintainance of the ports in section 3.2.1 - is it OK like this?
8314 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8316 SDCC source changes:
8317 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8323 processor registers declared internally by the port are emitted in
8324 the translation as equates,
8325 * src/pic16/gen.c: inline code is passed unprocessed to the

8351 UPPER for immediate operands,
8352 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8354 * src/pic16/peeph.def: all peepholes with movff are commented out,
8355 because there is a problem in the pcode peep optimizer,
8356 * src/pic16/ralloc.c: the register allocator can now reuse local
8357 function symbols for another function. This saves register usage.

8449 include information about variables allocated to the overlay
8452 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8454 * as/mcs51/lkmain.c: Help about -Y option

8466 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8468 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8469 (default behaviour).
8471 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8473 A python script to validate compiler diagnostic messages. It can be
8474 used to verify that sdcc complains about bad c source code and
8475 gives a good location of the error.
8476 * support/valdiag/Makefile,
8477 * support/valdiag/valdiag.py,
8478 * support/valdiag/tests/*
8480 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8494 around the header file.
8495 Bug reported from Jesus Calvino-Fraga
8497 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8499 * sdcc.spec: updated
8500 * device/include/Makefile.in: don't install CVS directories
8501 * device/lib/Makefile.in: added removal of CVS directories after install
8502 * doc/Makefile: fixed install, added local_icons
8503 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8504 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8505 * src/ds390/gen.c (genRightShift): fixed bug #870788
8506 * src/SDCCast.c (decorateType): fixed bug #870781
8508 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8510 PIC16 port related changes:
8511 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8512 added variable stackPos,
8514 * gen.c: genCall, assignResultValue: added support for
8515 pushing/retrieving function parameters to/from stack,
8516 genFunction,genEndFunction: setup stack frame for the
8518 genAddrOf: will be changed according to bug 863624
8520 * added files genutils.c and genutils.h which contain gen*
8521 debugged and optimised functions extracted from gen.c
8523 * glue.c: added variable 'externs' which holds extern symbols,
8524 pic16emitRegularMap: is modified to properly handle relocatable
8525 symbols under the new scheme,
8526 pic16createInterruptVect: is modified
8527 pic16printPublics: is modified to emit 'global' assembler directives,
8528 added pic16_printExterns to print extern symbols,
8529 pic16glue: initializes stack/frame pointer in the beginning of
8530 the assembly output. Temporary hack, will be corrected later,
8531 because gplink yet does not support stack and SDCC does not
8532 yet support a type of crt0.o object to create the final binary.
8534 * Removed many lines that contain 8051 legacy code.
8535 * The code is finally placed under a 'code' directive.
8536 * Added port specific options.
8538 * _process_pragma: simplified since now we do not need *special*
8539 include file to define SFR registers. But a separate header
8540 will be needed. This will be developed later.
8541 * _pic16_parseOptions: added, parses port specific options:
8542 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8543 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8544 --preplace-udata-with=
8546 * _pic16_setDefaultOptions: modified to initialize section names,
8547 but hack is temporarly out of order since it needs improvement.
8548 * _pic16_genAssemblerPreamble: configuration words are emitted by
8549 their address instead of their name. This part is incomplete and
8550 supports only the 18Fxx2 devices. Other devices will emit an error
8551 during assembly since they do not contain the same set of config
8553 * _pic16_genIVT: is modified,
8555 * pcode.c: added definitions for some hardware registers that are needed
8557 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8558 All PCI entries are updated. Now LFSR is supported.
8559 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8560 * added pic16_newpCodeOpLit2 to support instructions with
8561 two literal arguments
8562 * pic16_pCode2str: corrected code that emits assembler instructions
8563 with two literal operands and those that have an access bit modifier
8564 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8565 this fixes a bug which caused some labels to be lost, when an
8566 assembler directive was added, i.e. banksel,
8567 * pic16_FixRegisterBanking: improved logic that causes the insertion
8569 * InlineFunction: functions that are called once, are not any more
8570 inlined. This can be a port option in the future,
8572 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8574 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8575 hold the corresponding uninitialized symbols,
8576 * pic16_allocProcessorRegister: registers have explicit marked the
8578 * pic16_allocInternalRegister: registers are explicit marked as
8580 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8581 processing list, so bit registers were lost,
8584 * ralloc.h: added field 'accessBank' and original symbol operand
8585 in register definition,
8586 * removed the field isMapped from register definition,
8588 ** Several functions have been removed from various sources:
8589 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8590 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8591 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8592 pic16_assignRelocatableRegisters
8594 ** others have been introduced:
8595 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8596 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8598 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8600 * support/scripts/inc2h.pl: changed definition of BIT_AT
8601 to emit 'sbit at' instead of 'bit at'. This was a request.
8603 PIC16 port related preliminary changes:
8604 * gen.c: prefixed function popRegFromString with
8605 pic16_ and all references to it corrected
8606 * pcode.c: all pic16_pc_* hardware registers prefixed
8607 with underscore (_),
8608 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8609 * ralloc.c: newReg(): when register is REG_SFR then
8610 set address to rIdx,
8611 pic16_allocProcessorRegister(): marks register wasUsed=0
8612 pic16_writeUsedRegs(): added a call to assign processor
8613 registers via pic16_assignFixedRegisters
8615 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8617 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8618 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8619 variables in unused register banks. Also the SSEG is placed
8620 wherever there is enough space for it, and IDATA can be anywhere
8621 in internal RAM. For now compile using -Wl-Y[stack_size].
8622 The mem file is different for this option as well, since it
8623 makes no sense of talking about DSEG lenght.
8625 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8627 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8628 in certain cases, e.g. when ROM assignment, patch provided
8629 from Albert den Haan.
8631 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8774 * src/mcs51/peephole.def,
8775 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9654 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9655 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

9674 A few small changes that speed up the peephole optimizer.
9678 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9680 Try to make the peephole optimizer smarter by maintaining
9681 an association between the assembly source code and the
9682 iCodes that originated them. Put this information to use
9683 with a new peephole rule condition "notVolatile" so that
9684 the rules can be aggressive yet still safe.
9689 * src/mcs51/peeph.def
9691 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9695 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9696 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9697 if the left or right operand symbols have the accuse flag set.
9699 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9701 Changed the type of the result of the ! (NOT) operator to char;
9702 previously it returned the same type as the source. This allows
9703 us to eliminate all the genFloatNot functions (all of its target
9704 implementations were very buggy) since !float can use the same
9707 * src/SDCCicode.c (ast2iCode): ! returns char

9716 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9717 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9718 during interrupts. Ensure WSAVE is located at a shared bank address.
9719 2. Fixed page selection in some places
9720 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9721 the registers name strings.
9722 4. Fixed "signed / unsigned compare" compiler warnings.
9723 5. The PIC port manages its own allocation of the general purpose
9724 registers, but makes no attempt to reuse them. As a result when
9725 compiling it soon runs out of general purpose registers. Some
9726 additional code was added to the files pcode.c and device.c to walk
9727 through the function call tree and rename the registers so that they
9737 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9738 genPlus() & genMinus() when the result is the same as left or right

9744 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9746 Made bitfield a distinct type from bit so that bitfields
9747 convert as per ANSI C and bits retain their traditional
9748 boolean style behaviour. Implemented bitfield support in
9756 * src/ds390/gen.c: bit v bitfield split
9757 * src/z80/gen.c: New support for bitfields
9758 * support/regression/tests/bitfields.c: reenabled z80,
9761 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9763 Rules 246.x, 247.x relate to bitfields, the others speed up
9764 access to xdata mapped I/O devices.
9766 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9768 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9770 Cleaned up genPackBits and genUnpackBits and added two helper

9780 Fixed bug #748310 (pointer to function type mishandled when the
9781 function name is omitted). Also fixed a SIGSEGV when a function
9782 attribute (reentrant, etc) is used on a non-function or on a
9783 function but misplaced before the parameter list.

9812 Made the constant following the "interrupt" keyword optional. If
9813 omitted, the function will not automatically be given an entry
9814 in the interrupt vector table (similar to #pragma NOIV, but
9815 less syntacticly kludgy). The interrupt number is also now
9816 range checked. Also fixed a bug in the high order bit example
9823 * support/Util/SDCCerr.c
9824 * support/Util/SDCCerr.h
9827 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9835 be re-activated by defining REDUCE_LITERALS)
9836 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9837 unsigned, but are signed by default
9838 * src/SDCCval.c (constVal): rearranged
9839 * src/SDCCval.c (valMod): preliminary fix
9840 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9883 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9884 * src/SDCCval.c (valDiv, valMod): fixed signdness
9885 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9886 signedness of modulo, left and right shift
9887 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

10346 added if/endif conditional macros to remove options help
10347 messages from optionsTable when a port is not configured, added
10348 support for the PIc16 port in the ports table, when executing
10349 the compiler with no port specified on command line, a default
10350 port is selected with the new macro DEFAULT_PORT which is
10351 defined in port.h, in setDefaultOptions() linkOptions is removed
10352 from initialization assignment, since now it is a set,
10353 parseCmdLine uses setParseWithComma for linkOptions, in
10354 linkEdit() linkOptions are accessed with new function indexSet()
10355 which returns the i'th item of a set variable. See SDCCset.c, in
10356 linkEdit() when calling buildCmdLine(), added linkOptions as
10357 last argument. Now users can pass arguments to gplink via the

11429 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11430 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11439 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11440 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11442 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11444 * in /sdcc/as/mcs51/ changed these files in order to create an
11445 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11446 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11447 following files to include the previous two files: aslink.dsp,
11448 Makefile.aslink, Makefile.bcc, and Makefile.in.
11450 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11451 .adb instead of .cdb
11453 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11455 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11456 value from option --iram-size.
11458 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11460 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11463 2002-09-18 <wiml AT hhhh.org>
11465 * SDCClrange.h: exposed setFromRange() and setToRange()
11466 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11467 packRegsForAccUse() (bug 542397)
11468 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11469 multiple times and emitting the fetch operations more than once
11470 added aopGetUsesAcc() function to allow binary operators to
11471 fetch their operands in the correct order; made genMinus() emit
11472 compact code for X = LITERAL - Y
11474 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11475 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11476 sprintf() in line 1267.
11478 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11479 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11482 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11483 Changes to aslink (All the changes are marked with 'JCF'):
11485 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11488 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11489 area BSEG. Also moves, if possible, the DATA area down into the internal
11490 ram so more space is available.
11492 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11495 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11496 not bytes. Function summary() which creates a memory usage summary
11497 file with extension .mem. Reports of overlaping stack and small stack
11498 size. If the space for the stack is less than 16 bytes aslink trows a
11501 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11502 the 8051. Option 'y' for memory summary output file.
11504 Changes to sdcc (All the changes are marked with 'JCF'):
11506 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11508 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11509 overlaying area for it (uses RegBankUsed[4]).
11511 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11512 bank zero as used by default. By default aslink locates the stack
11513 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11514 the creation of the .mem file. Delegates the allocation of data area
11515 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11516 the begining of the stack area to aslink.
11518 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11519 glue() in SDCCglue.c creates an area for it.
11521 2002-09-03 Borut Razem <borut.razem AT siol.net>
11522 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11523 sdcc/src/pic/glue.c:
11524 introduced atexit() handler for teporay files removal in case of
11525 errors, assertions, ...
11527 2002-08-29 Borut Razem <borut.razem AT siol.net>
11528 * sdcc/support/cpp2/auto-host_vc_in.h:
11529 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11530 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11531 Maybe there is a similar problem with BORLANDC? It should be checked!
11533 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11534 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11535 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11536 was not executed, and the compiler (cl) launched a warning:
11537 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11539 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11540 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11542 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11543 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11545 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11546 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11547 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11548 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11549 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11550 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11551 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11552 - added Release configuration in VS projects
11553 - review of compiler an linker options
11554 - VC .exe files are generated in bin_vc directory, not to interfere
11555 with binaries generated from other projects (cygwin, mingw, bcc ...)
11557 * sdcc/src/yacc.dsp: added
11559 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11560 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11561 and insert the version number definitions from .version
11563 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11565 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11566 added - genarate auto-host.h using auto-host_vc_in.h as template
11569 removed from CVS, generated automatically
11571 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11572 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11574 2002-08-11 Borut Razem <borut.razem AT siol.net>
11575 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11577 2002-08-10 Borut Razem <borut.razem AT siol.net>
11578 * src/SDCCmain.c (main):
11579 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11580 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11581 The consequence was that some temporary files were not removed.
11584 unification of code in functions tempfilename() and tempfile():
11585 function tempnam() is defined in Visual Studio 6.0 and .NET
11587 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11589 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11590 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11591 - removed compiler command line option /WX: Treats all warnings as errors
11592 - update a list of source files, included into the project
11594 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11595 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11596 changed project type to Generic Project so that can be correcly converted to VS.NET project
11598 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11600 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11602 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11604 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11605 added return 0 statements after assert() to make compiler happy
11607 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11608 added newline in the def file to keep MSC compiler satisfied
11610 * sdcc/src/z80/gen.c:
11611 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11612 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
