1572 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1574 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1575 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1577 One basic decision: e.g. src/clean.mk includes further files. In order
1578 to make this work there are two solutions:
1579 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1580 run configure on them. This way they can use
1581 'include $(srcdir)/port-clean.mk'
1582 - always include clean.mk by the Makefile at the same level. To avoid
1583 that `make clean` tries to include and build Makefile.dep the
1584 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1585 implemented, because now even `make uninstall` doesn't create
1586 Makefile.in. clean.mk could be eliminated by pasting it in
1589 * debugger/mcs51/Makefile.in: build own objects from library sources
1590 (SLIB, SDCC) in current directory
1592 * configure, configure.in: renamed --disable-device-lib-build in
1593 --disable-device-lib; added --enable-doc, the required tools are
1594 searched by configure; added result message; the toolchain for the
1595 belonging ports are now only built, if the port is enabled.
1597 * support/regression/*: all output is written in directory gen, because
1598 the fwk and ports directories don't livet in the build tree using vpath
1600 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1601 --disable-device-lib, added --enable-doc, added section VPATH
1603 * sim/ucsim/configure.in,
1604 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1605 z80 are enabled by default
1607 2006-04-24 Raphael Neider <rneider AT web.de>
1609 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1610 to config word, "pic14_"-prefixed some extern functions
1611 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1612 config word has been found
1613 * src/pic/device.h: added prototypes
1614 * src/pic/pcode.c: added "pic14_"-prefix where needed
1615 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1617 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1631 fixes #1469504 and #1474602,
1632 (pCodeRegOptimizeRegUsage): fixed typo in comment

1864 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1866 * src/SDCCpeeph.c (operandsLiteral): new, added,

1878 implemented patch 1120823 Thanks to Willy De la Court (normal
1879 interrupts need an interrupt number now if they are made critical),
1880 and enabled nesting of critical functions though not for gbz80
1881 (genCritical, genEndCritical): added functions
1882 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1883 * src/z80/mappings.i: added "ei" to all mappings

1892 2006-03-16 Raphael Neider <rneider AT web.de>
1894 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1895 the left operand is shorter than the result (c* = lit-c* + int),
1897 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1900 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1902 * src/.version: increased version number to 2.5.5
1903 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1904 linking is done manually in pic16 port's _linkEdit,
1905 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1906 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1907 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1908 allocate asmop as AOP_ACC,
1909 (aopForRemat): added parameter 'bool result' in function declaration,
1910 (pic16_aopGet): return AOP_ACC when accessing WREG,
1911 (pic16_popGetTempReg): minor modification,
1912 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1913 'pic16_allocWithIdx',
1914 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1915 calling function in absolute addresses,
1916 (genAssign): take into account AOP_ACC asmop,
1917 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1918 * src/pic16/pcoderegs.c: some debug functions and lines added,

1920 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1922 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1923 call to allocReg, not by manually allocating a new one,
1924 (pic16_assignRegisters): now before going through the register
1925 allocating functions mark all registers as free. This eliminates some
1926 side effects resulting from peephole parser done earlier in the backbone
1928 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1930 * src/SDCCicode.c (geniCodeLogic),

1950 (aopForSym, aopOp): increment asmop.allocated if reused,
1951 (freeAsmop): decrement asmop.allocated and check for zero instead of
1953 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1954 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1986 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1987 which dumps before the function entry point a data byte which represents
1988 the number of the local variables used by the specified function, added
1989 'xinst' for initial support for Extended Instruction Support,
1990 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1991 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1992 port->fun_prefix anymore (may change later),
1993 (genFunction, genEndFunction): do not store/restore local registers for
1994 _main (this should take care the --main-return command line option in
1996 (genOr): removed some legacy pic-port instructions,
1997 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1998 performing operations with SFR's causes data to be written more than
1999 once to each SFR. Perhaps SFRs should be handled in special cases...
2000 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2002 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2003 into account for stack starting position,

2005 --extended or -y for Extended Instruction Support,
2006 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2007 (deassignLRs): *** perhaps the most important change, old 'for' code
2008 (commented out for reference), didn't account for some registers which
2009 were left marked 'not free' after a pointer operation. The change
2010 reduces register usage a lot in some cases

4335 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4336 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4337 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4338 immedDom() returning wrong block; probably fixes bug #1160833)
4340 2005-03-20 Borut Razem <borut.razem AT siol.net>
4342 * support/scripts/inc2h.pl: WIN32 port
4344 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4346 * device/lib/makefile.in: added abs.c and labs.c
4348 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4350 * device/include/stdint.h: added
4351 * device/lib/abs.c: added
4352 * device/lib/labs.c: added
4353 * device/include/stdlib.h: added abs() and labs() prototypes
4354 * device/lib/libsdcc.lib: added abs and labs
4355 * device/include/float.h,
4356 * device/lib/_fsmul.c,
4357 * device/lib/printf_fast.c,
4358 * device/lib/printf_tiny.c: updated comments
4360 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4362 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4365 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4367 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4368 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4370 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4372 * device/lib/printf_large.c: removed inline assembly for portability and
4373 readability. Use printf_fast if speed or size are more important.
4374 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4375 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4377 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4379 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4380 prevent compiler warning
4382 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4384 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4385 moved to level 0 and declared as static. Also they are explicit
4386 placed in access bank. This was necessery because some times they
4387 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4388 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4389 optimizations. Currently only compare to unsigned char is implemented,
4390 * src/pic16/gen.c: added fReturnIdx array,
4391 * (struct resolvedIfx) is moved to gen.h and made public,
4392 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4393 * (aopForSym): added an optimization to directly store in stack of
4394 the operand of a SEND iCode,
4395 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4396 but as registers instead (AOP_REG) using the fReturnIdx array,
4397 * (pic16_freeAsmop): remove the freed register from the
4398 _G.sregsAlloc field,
4399 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4400 a compare of 'WREG',
4401 * (pic16_popGetTempRegCond): changed function prototype, now
4402 function takes also a bitVector argument v which holds the current
4403 set of registers that are allocated for stack access by aopForSym,
4404 registers allocated in aopForSym for accessing stack symbols are not
4405 any more part of the functions usedRegs field,
4406 * (genCall): some times aopOp is called for a stack variable to be
4407 send, aopForSym might perform the push, if this is true make sure
4408 that genCall doesn't push the variable twice by testing _G.resDirect,
4409 * (genFunction): changed testing for unspecified interrupt number
4410 from 256 to INTNO_UNSPEC,
4411 * modified selection scheme of frame pointer generation. Previously
4412 if function did use local registers a frame pointer was generated,
4413 now a frame pointer is generated only if function has arguments
4414 (that need PLUSW2 register access), or has stack arguments, or the
4415 compiler is not instructed to omit the frame pointer,
4416 * (genEndFunction): before restoring local registers that were saved
4417 in the function preamble, also restore the registers that *might*
4418 have been allocated for stack access,
4419 * (genRet): removed some old comments,
4420 * (genCmp, the active (RN's) version): added a call to the
4421 pic16_genCmp_special function to perform the compare with a more
4422 robust and optimized way,
4423 * (genInline): a feature has been added in inline code generation,
4424 which allows a wildcard variable substitution when writing inline
4425 assembly. Code is incomplete and experimental therefore undocumented,
4426 * (genCast): changed order of aopOp for result and right to allow
4427 aopForSym to directly load the result if possible,
4428 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4429 perform an optimized compare on some selected special occasions,
4430 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4431 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4432 generate an IVT any more,
4433 * src/pic16/main.c (pic16_optionsTable): added command line option
4435 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4436 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4438 * src/pic16/NOTES: Raphael Neider added in list of active developers
4439 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4440 jumptable_end to prevent bug #,
4441 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4442 inCond and outCond fields,
4443 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4444 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4445 turn off register spilling,
4446 * (packRegsForOneUse): synced with other ports' versions although it
4447 is not used currently,
4448 * (pic16_packRegisters): added an optimization while reading
4449 structure bitfields, some registers may be saved (malloc code is
4450 decreased by 80 bytes)
4452 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4454 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4455 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4456 this can be optimized more?
4458 2005-03-10 Raphael Neider <rneider AT web.de>
4460 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4461 genNearPointerGet): (hopefully) fixed access to bitfields via
4462 pointers (p->bitN = x; and x = p->bitN; failed)
4464 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4505 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4507 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4508 to keep the correct label reference count when adding/removing references
4509 to labels. A peephole file using this is appended to patch #1144962.

4651 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4652 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4653 this might fix SIGSEGVs on MinGW...
4654 * src/SDCCopt.c (killDeadCode): restored original behaviour
4655 (volatile operands might get thrown away though)
4657 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4741 * (genUminus): rewritten to for efficiency
4742 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
4743 used uninitialized in some cases)

4745 copy the third byte from the int -- now assumes 0x80 (data memory)
4746 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4747 operands (genAddLit expects the iCode's operands to swapped as
4748 well), fixed leftover bytes (crashed for short left operands)

5097 generated for switch statements. For now you need to set the
5098 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5099 Now 4 algorithms for mcs51 jumptable generation are used:
5100 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5132 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5134 * added libc directory. The current version of LibC contains string
5135 functions, ctype functions and macros and some functions of the
5136 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5137 be extensively tested in the future. Standard disclaimer here.
5138 Library is not automatically build yet. But one can build it by

5150 * (pic16_storeForReturn): optimized return of 0,
5151 * (genCmp): experimental code for new genCmp which uses PIC18's
5152 special compare&skip instructions. Initial tests fail some times
5153 with variables grater than 1 byte in size, so new code is disabled,
5154 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5156 * (genCast): began a fix to optimize the casting of a bit to another
5157 bit, now assigning a bitfield to another bitfield will fail, sorry,

5166 and 1 for banking instruction,
5167 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5168 caused stop processing pCodes after a inline assembly block,
5169 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5171 registers when it shouldn't,
5172 * src/pic16/ralloc.c (allocReg): add preliminary support for
5173 supporting a limited set of temporary registers,
5175 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5177 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5178 genDataPointerSet): ensure assignments always copy in MSB to LSB
5180 (loadRegFromAop): recognize CLRH optimization,
5181 (genFunction): optimize RECEIVE iCodes in reentrant functions
5183 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5185 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8180 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8182 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8183 loaded with the linker search paths (-L arguments) and the libraries
8184 to be linked with the current source (-l arguments). Changes
8185 currently will affect only the pic16 port.
8186 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8187 include path the port specific paths and port specific libraries,
8188 * gplink command now contains the $3 argument,
8189 * src/pic16/device.h,
8190 * src/pic16/device.c,: structure PIC_device is made public and
8191 renamed to PIC16_device, the same for variable Pics which is renamed

8206 Documenting changes from previous commits.
8207 * configure.in (version 1.56),
8208 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8209 when generating output files to configure the pic16 library,
8210 but now I've commented it out, since gputils aren't installed in the
8211 SF compile farm, so library won't compile
8213 * device/lib/Makefile.in (version 1.56): initially I've added in
8214 target 'all' the prerequestive 'model-pic16' so it compiled the
8215 pic16 library, but now I've commented it out for the same reasons
8217 * added targets 'model-pic16' and 'objects-pic16' to compile the
8219 * added target 'port-specific-objects-pic16' to handle the
8220 generated libraries and copy them into the build/ directory
8221 * added target 'clean-intermediate-pic16' to clean intermediate
8222 files into pic16 directory
8223 * in target 'installdirs' added line to create directory pic16 in
8224 the installation path
8226 * device/include/Makefile.in (version 1.11): in target 'install'
8227 added lines to copy all header files to installation path,
8228 * in target 'installdirs' added line create directory for pic16
8229 headers in the installation path

8244 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8245 option so that it actually works. Made it specific to the z80, since
8246 the gbz80 doesn't have these kinds of I/O ports.
8248 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8250 * device/include/z180.h,

8272 Mainly changes to support compilation of the device libraries
8273 * src/pic16/device.c: stack is allocated via symbol and not
8274 via literal number. The symbol is placed in the corresponding
8275 position of the data ram
8276 * (pic16_dump_section): relocatable and absolute uninitialized
8277 data are now emitted in sorted order to reduce section naming,
8278 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8279 weren't marked as being in the access bank,
8281 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8283 Added portion of GNU PIC Library under the directory
8284 device/include/pic16 and device/lib/pic16. These files
8285 contain the declarations of SFRs for the PIC18Fxx2 devices.
8286 The directory is initialized via configure from toplevel.
8288 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8313 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8315 * doc/sdccman.lyx: Moved and added some sections, small changes
8316 all over. Telling LaTeX to be less strict with word spacing
8317 to better keep the right margin. Changed some notes about
8318 maintainance of the ports in section 3.2.1 - is it OK like this?
8320 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8322 SDCC source changes:
8323 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8329 processor registers declared internally by the port are emitted in
8330 the translation as equates,
8331 * src/pic16/gen.c: inline code is passed unprocessed to the

8357 UPPER for immediate operands,
8358 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8360 * src/pic16/peeph.def: all peepholes with movff are commented out,
8361 because there is a problem in the pcode peep optimizer,
8362 * src/pic16/ralloc.c: the register allocator can now reuse local

8439 2004-01-07 Borut Razem <borut.razem AT siol.net>
8441 * support/scripts/sdcc.nsi: update PATH
8442 * support/scripts/sdcc.ico: craeted

8472 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8474 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8475 (default behaviour).
8477 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8479 A python script to validate compiler diagnostic messages. It can be
8480 used to verify that sdcc complains about bad c source code and
8481 gives a good location of the error.
8482 * support/valdiag/Makefile,
8483 * support/valdiag/valdiag.py,
8484 * support/valdiag/tests/*

8500 around the header file.
8501 Bug reported from Jesus Calvino-Fraga
8503 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8505 * sdcc.spec: updated
8506 * device/include/Makefile.in: don't install CVS directories
8507 * device/lib/Makefile.in: added removal of CVS directories after install
8508 * doc/Makefile: fixed install, added local_icons
8509 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8510 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8511 * src/ds390/gen.c (genRightShift): fixed bug #870788
8512 * src/SDCCast.c (decorateType): fixed bug #870781
8514 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8516 PIC16 port related changes:
8517 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8518 added variable stackPos,
8520 * gen.c: genCall, assignResultValue: added support for
8521 pushing/retrieving function parameters to/from stack,
8522 genFunction,genEndFunction: setup stack frame for the
8524 genAddrOf: will be changed according to bug 863624
8526 * added files genutils.c and genutils.h which contain gen*
8527 debugged and optimised functions extracted from gen.c
8529 * glue.c: added variable 'externs' which holds extern symbols,
8530 pic16emitRegularMap: is modified to properly handle relocatable
8531 symbols under the new scheme,
8532 pic16createInterruptVect: is modified
8533 pic16printPublics: is modified to emit 'global' assembler directives,
8534 added pic16_printExterns to print extern symbols,
8535 pic16glue: initializes stack/frame pointer in the beginning of
8536 the assembly output. Temporary hack, will be corrected later,
8537 because gplink yet does not support stack and SDCC does not
8538 yet support a type of crt0.o object to create the final binary.
8540 * Removed many lines that contain 8051 legacy code.
8541 * The code is finally placed under a 'code' directive.
8542 * Added port specific options.
8544 * _process_pragma: simplified since now we do not need *special*
8545 include file to define SFR registers. But a separate header
8546 will be needed. This will be developed later.
8547 * _pic16_parseOptions: added, parses port specific options:
8548 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8549 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8550 --preplace-udata-with=
8552 * _pic16_setDefaultOptions: modified to initialize section names,
8553 but hack is temporarly out of order since it needs improvement.
8554 * _pic16_genAssemblerPreamble: configuration words are emitted by
8555 their address instead of their name. This part is incomplete and
8556 supports only the 18Fxx2 devices. Other devices will emit an error
8557 during assembly since they do not contain the same set of config
8559 * _pic16_genIVT: is modified,
8561 * pcode.c: added definitions for some hardware registers that are needed
8563 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8564 All PCI entries are updated. Now LFSR is supported.
8565 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8566 * added pic16_newpCodeOpLit2 to support instructions with
8567 two literal arguments
8568 * pic16_pCode2str: corrected code that emits assembler instructions
8569 with two literal operands and those that have an access bit modifier
8570 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8571 this fixes a bug which caused some labels to be lost, when an
8572 assembler directive was added, i.e. banksel,
8573 * pic16_FixRegisterBanking: improved logic that causes the insertion
8575 * InlineFunction: functions that are called once, are not any more
8576 inlined. This can be a port option in the future,
8578 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8580 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8581 hold the corresponding uninitialized symbols,
8582 * pic16_allocProcessorRegister: registers have explicit marked the
8584 * pic16_allocInternalRegister: registers are explicit marked as
8586 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8587 processing list, so bit registers were lost,
8590 * ralloc.h: added field 'accessBank' and original symbol operand
8591 in register definition,
8592 * removed the field isMapped from register definition,
8594 ** Several functions have been removed from various sources:
8595 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8596 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8597 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8598 pic16_assignRelocatableRegisters
8600 ** others have been introduced:
8601 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8602 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8604 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8606 * support/scripts/inc2h.pl: changed definition of BIT_AT
8607 to emit 'sbit at' instead of 'bit at'. This was a request.
8609 PIC16 port related preliminary changes:
8610 * gen.c: prefixed function popRegFromString with
8611 pic16_ and all references to it corrected
8612 * pcode.c: all pic16_pc_* hardware registers prefixed
8613 with underscore (_),
8614 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8615 * ralloc.c: newReg(): when register is REG_SFR then
8616 set address to rIdx,
8617 pic16_allocProcessorRegister(): marks register wasUsed=0
8618 pic16_writeUsedRegs(): added a call to assign processor
8619 registers via pic16_assignFixedRegisters
8621 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8623 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8624 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8625 variables in unused register banks. Also the SSEG is placed
8626 wherever there is enough space for it, and IDATA can be anywhere
8627 in internal RAM. For now compile using -Wl-Y[stack_size].
8628 The mem file is different for this option as well, since it
8629 makes no sense of talking about DSEG lenght.
8631 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8633 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8634 in certain cases, e.g. when ROM assignment, patch provided
8635 from Albert den Haan.
8637 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8780 * src/mcs51/peephole.def,
8781 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9660 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9661 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9662 type for bits was changed. It resulted in bit variables becoming
9663 global, which is not permitted in PIC 14 assembly output.

9680 A few small changes that speed up the peephole optimizer.
9684 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9686 Try to make the peephole optimizer smarter by maintaining
9687 an association between the assembly source code and the
9688 iCodes that originated them. Put this information to use
9689 with a new peephole rule condition "notVolatile" so that
9690 the rules can be aggressive yet still safe.
9695 * src/mcs51/peeph.def
9697 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9701 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9702 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9703 if the left or right operand symbols have the accuse flag set.
9705 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9707 Changed the type of the result of the ! (NOT) operator to char;
9708 previously it returned the same type as the source. This allows
9709 us to eliminate all the genFloatNot functions (all of its target
9710 implementations were very buggy) since !float can use the same
9713 * src/SDCCicode.c (ast2iCode): ! returns char

9715 * src/ds390/gen.c (genNot, genNotFloat),
9716 * src/z80/gen.c (genNot, genNotFloat),

9722 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9723 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9724 during interrupts. Ensure WSAVE is located at a shared bank address.
9725 2. Fixed page selection in some places
9726 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9727 the registers name strings.
9728 4. Fixed "signed / unsigned compare" compiler warnings.
9729 5. The PIC port manages its own allocation of the general purpose
9730 registers, but makes no attempt to reuse them. As a result when
9731 compiling it soon runs out of general purpose registers. Some
9732 additional code was added to the files pcode.c and device.c to walk
9733 through the function call tree and rename the registers so that they
9743 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9744 genPlus() & genMinus() when the result is the same as left or right

9750 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9752 Made bitfield a distinct type from bit so that bitfields
9753 convert as per ANSI C and bits retain their traditional
9754 boolean style behaviour. Implemented bitfield support in
9762 * src/ds390/gen.c: bit v bitfield split
9763 * src/z80/gen.c: New support for bitfields
9764 * support/regression/tests/bitfields.c: reenabled z80,
9767 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9769 Rules 246.x, 247.x relate to bitfields, the others speed up
9770 access to xdata mapped I/O devices.
9772 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9774 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9776 Cleaned up genPackBits and genUnpackBits and added two helper

9786 Fixed bug #748310 (pointer to function type mishandled when the
9787 function name is omitted). Also fixed a SIGSEGV when a function
9788 attribute (reentrant, etc) is used on a non-function or on a
9789 function but misplaced before the parameter list.

9816 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9818 Made the constant following the "interrupt" keyword optional. If
9819 omitted, the function will not automatically be given an entry
9820 in the interrupt vector table (similar to #pragma NOIV, but
9821 less syntacticly kludgy). The interrupt number is also now
9822 range checked. Also fixed a bug in the high order bit example
9829 * support/Util/SDCCerr.c
9830 * support/Util/SDCCerr.h

9841 be re-activated by defining REDUCE_LITERALS)
9842 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9843 unsigned, but are signed by default
9844 * src/SDCCval.c (constVal): rearranged
9845 * src/SDCCval.c (valMod): preliminary fix
9846 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9890 * src/SDCCval.c (valDiv, valMod): fixed signdness
9891 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9892 signedness of modulo, left and right shift

10352 added if/endif conditional macros to remove options help
10353 messages from optionsTable when a port is not configured, added
10354 support for the PIc16 port in the ports table, when executing
10355 the compiler with no port specified on command line, a default
10356 port is selected with the new macro DEFAULT_PORT which is
10357 defined in port.h, in setDefaultOptions() linkOptions is removed
10358 from initialization assignment, since now it is a set,
10359 parseCmdLine uses setParseWithComma for linkOptions, in
10360 linkEdit() linkOptions are accessed with new function indexSet()
10361 which returns the i'th item of a set variable. See SDCCset.c, in

11448 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11450 * in /sdcc/as/mcs51/ changed these files in order to create an
11451 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11452 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11453 following files to include the previous two files: aslink.dsp,
11454 Makefile.aslink, Makefile.bcc, and Makefile.in.
11456 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11457 .adb instead of .cdb
11459 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11461 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11462 value from option --iram-size.
11464 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11466 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11469 2002-09-18 <wiml AT hhhh.org>
11471 * SDCClrange.h: exposed setFromRange() and setToRange()
11472 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11473 packRegsForAccUse() (bug 542397)
11474 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11475 multiple times and emitting the fetch operations more than once
11476 added aopGetUsesAcc() function to allow binary operators to
11477 fetch their operands in the correct order; made genMinus() emit
11478 compact code for X = LITERAL - Y
11480 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11481 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11482 sprintf() in line 1267.
11484 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11485 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11488 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11489 Changes to aslink (All the changes are marked with 'JCF'):
11491 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11494 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11495 area BSEG. Also moves, if possible, the DATA area down into the internal
11496 ram so more space is available.
11498 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11501 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11502 not bytes. Function summary() which creates a memory usage summary
11503 file with extension .mem. Reports of overlaping stack and small stack
11504 size. If the space for the stack is less than 16 bytes aslink trows a
11507 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11508 the 8051. Option 'y' for memory summary output file.
11510 Changes to sdcc (All the changes are marked with 'JCF'):
11512 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11514 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11515 overlaying area for it (uses RegBankUsed[4]).
11517 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11518 bank zero as used by default. By default aslink locates the stack
11519 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11520 the creation of the .mem file. Delegates the allocation of data area
11521 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11522 the begining of the stack area to aslink.
11524 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11525 glue() in SDCCglue.c creates an area for it.
11527 2002-09-03 Borut Razem <borut.razem AT siol.net>
11528 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11529 sdcc/src/pic/glue.c:
11530 introduced atexit() handler for teporay files removal in case of
11531 errors, assertions, ...
11533 2002-08-29 Borut Razem <borut.razem AT siol.net>
11534 * sdcc/support/cpp2/auto-host_vc_in.h:
11535 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11536 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11537 Maybe there is a similar problem with BORLANDC? It should be checked!
11539 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11540 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11541 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11542 was not executed, and the compiler (cl) launched a warning:
11543 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11545 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11546 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11548 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11549 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

11552 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11553 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11554 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11555 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11556 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11557 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11558 - added Release configuration in VS projects
11559 - review of compiler an linker options
11560 - VC .exe files are generated in bin_vc directory, not to interfere
11561 with binaries generated from other projects (cygwin, mingw, bcc ...)
11563 * sdcc/src/yacc.dsp: added
11565 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11566 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11567 and insert the version number definitions from .version
11569 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11571 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11572 added - genarate auto-host.h using auto-host_vc_in.h as template
11575 removed from CVS, generated automatically
11577 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11578 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11580 2002-08-11 Borut Razem <borut.razem AT siol.net>
11581 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11583 2002-08-10 Borut Razem <borut.razem AT siol.net>
11584 * src/SDCCmain.c (main):
11585 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11586 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11587 The consequence was that some temporary files were not removed.
11590 unification of code in functions tempfilename() and tempfile():
11591 function tempnam() is defined in Visual Studio 6.0 and .NET
11593 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11595 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11596 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11597 - removed compiler command line option /WX: Treats all warnings as errors
11598 - update a list of source files, included into the project
11600 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11601 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11602 changed project type to Generic Project so that can be correcly converted to VS.NET project
11604 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11606 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11608 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11610 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11611 added return 0 statements after assert() to make compiler happy
11613 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11614 added newline in the def file to keep MSC compiler satisfied
11616 * sdcc/src/z80/gen.c:
11617 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
