1960 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1962 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1963 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1965 One basic decision: e.g. src/clean.mk includes further files. In order
1966 to make this work there are two solutions:
1967 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1968 run configure on them. This way they can use
1969 'include $(srcdir)/port-clean.mk'
1970 - always include clean.mk by the Makefile at the same level. To avoid
1971 that `make clean` tries to include and build Makefile.dep the
1972 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1973 implemented, because now even `make uninstall` doesn't create
1974 Makefile.in. clean.mk could be eliminated by pasting it in
1977 * debugger/mcs51/Makefile.in: build own objects from library sources
1978 (SLIB, SDCC) in current directory
1980 * configure, configure.in: renamed --disable-device-lib-build in
1981 --disable-device-lib; added --enable-doc, the required tools are
1982 searched by configure; added result message; the toolchain for the
1983 belonging ports are now only built, if the port is enabled.
1985 * support/regression/*: all output is written in directory gen, because
1986 the fwk and ports directories don't livet in the build tree using vpath
1988 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1989 --disable-device-lib, added --enable-doc, added section VPATH
1991 * sim/ucsim/configure.in,
1992 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1993 z80 are enabled by default
1995 2006-04-24 Raphael Neider <rneider AT web.de>
1997 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1998 to config word, "pic14_"-prefixed some extern functions
1999 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2000 config word has been found
2001 * src/pic/device.h: added prototypes
2002 * src/pic/pcode.c: added "pic14_"-prefix where needed
2003 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2005 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2019 fixes #1469504 and #1474602,
2020 (pCodeRegOptimizeRegUsage): fixed typo in comment

2243 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2245 * src/mcs51/gen.c (genCall): fixed bug 1457608
2247 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2252 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2254 * src/SDCCpeeph.c (operandsLiteral): new, added,

2266 implemented patch 1120823 Thanks to Willy De la Court (normal
2267 interrupts need an interrupt number now if they are made critical),
2268 and enabled nesting of critical functions though not for gbz80
2269 (genCritical, genEndCritical): added functions
2270 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2271 * src/z80/mappings.i: added "ei" to all mappings
2273 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2275 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2276 submitted by the Debian SDCC maintainer Aurelien Jarno:
2277 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2278 archive with gcc 4.1 on mips and wrote the patch"
2280 2006-03-16 Raphael Neider <rneider AT web.de>
2282 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2283 the left operand is shorter than the result (c* = lit-c* + int),
2285 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2288 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2290 * src/.version: increased version number to 2.5.5
2291 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2292 linking is done manually in pic16 port's _linkEdit,
2293 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2294 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2295 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2296 allocate asmop as AOP_ACC,
2297 (aopForRemat): added parameter 'bool result' in function declaration,
2298 (pic16_aopGet): return AOP_ACC when accessing WREG,
2299 (pic16_popGetTempReg): minor modification,
2300 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2301 'pic16_allocWithIdx',
2302 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2303 calling function in absolute addresses,
2304 (genAssign): take into account AOP_ACC asmop,
2305 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2306 * src/pic16/pcoderegs.c: some debug functions and lines added,
2307 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2308 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2310 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2311 call to allocReg, not by manually allocating a new one,
2312 (pic16_assignRegisters): now before going through the register
2313 allocating functions mark all registers as free. This eliminates some
2314 side effects resulting from peephole parser done earlier in the backbone
2316 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2318 * src/SDCCicode.c (geniCodeLogic),

2337 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2338 (aopForSym, aopOp): increment asmop.allocated if reused,
2339 (freeAsmop): decrement asmop.allocated and check for zero instead of
2341 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2342 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2343 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2366 2006-03-06 Borut Razem <borut.razem AT siol.net>
2368 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2369 made the linker quiet
2371 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2373 * src/pic16/gen.c (genPcall): fixed bug #1443644
2374 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2375 which dumps before the function entry point a data byte which represents
2376 the number of the local variables used by the specified function, added
2377 'xinst' for initial support for Extended Instruction Support,
2378 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2379 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2380 port->fun_prefix anymore (may change later),
2381 (genFunction, genEndFunction): do not store/restore local registers for
2382 _main (this should take care the --main-return command line option in
2384 (genOr): removed some legacy pic-port instructions,
2385 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2386 performing operations with SFR's causes data to be written more than
2387 once to each SFR. Perhaps SFRs should be handled in special cases...
2388 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2390 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2391 into account for stack starting position,
2392 (struct OPTIONS pic16_optionsTable): added command line argument
2393 --extended or -y for Extended Instruction Support,
2394 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2395 (deassignLRs): *** perhaps the most important change, old 'for' code
2396 (commented out for reference), didn't account for some registers which
2397 were left marked 'not free' after a pointer operation. The change
2398 reduces register usage a lot in some cases
2400 2006-03-04 Borut Razem <borut.razem AT siol.net>
2402 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4723 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4724 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4725 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4726 immedDom() returning wrong block; probably fixes bug #1160833)
4728 2005-03-20 Borut Razem <borut.razem AT siol.net>
4730 * support/scripts/inc2h.pl: WIN32 port
4732 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4734 * device/lib/makefile.in: added abs.c and labs.c
4736 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4738 * device/include/stdint.h: added
4739 * device/lib/abs.c: added
4740 * device/lib/labs.c: added
4741 * device/include/stdlib.h: added abs() and labs() prototypes
4742 * device/lib/libsdcc.lib: added abs and labs
4743 * device/include/float.h,
4744 * device/lib/_fsmul.c,
4745 * device/lib/printf_fast.c,
4746 * device/lib/printf_tiny.c: updated comments
4748 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4750 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4753 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4755 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4756 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4758 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4760 * device/lib/printf_large.c: removed inline assembly for portability and
4761 readability. Use printf_fast if speed or size are more important.
4762 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4763 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4765 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4767 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4768 prevent compiler warning
4770 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4772 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4773 moved to level 0 and declared as static. Also they are explicit
4774 placed in access bank. This was necessery because some times they
4775 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4776 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4777 optimizations. Currently only compare to unsigned char is implemented,
4778 * src/pic16/gen.c: added fReturnIdx array,
4779 * (struct resolvedIfx) is moved to gen.h and made public,
4780 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4781 * (aopForSym): added an optimization to directly store in stack of
4782 the operand of a SEND iCode,
4783 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4784 but as registers instead (AOP_REG) using the fReturnIdx array,
4785 * (pic16_freeAsmop): remove the freed register from the
4786 _G.sregsAlloc field,
4787 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4788 a compare of 'WREG',
4789 * (pic16_popGetTempRegCond): changed function prototype, now
4790 function takes also a bitVector argument v which holds the current
4791 set of registers that are allocated for stack access by aopForSym,
4792 registers allocated in aopForSym for accessing stack symbols are not
4793 any more part of the functions usedRegs field,
4794 * (genCall): some times aopOp is called for a stack variable to be
4795 send, aopForSym might perform the push, if this is true make sure
4796 that genCall doesn't push the variable twice by testing _G.resDirect,
4797 * (genFunction): changed testing for unspecified interrupt number
4798 from 256 to INTNO_UNSPEC,
4799 * modified selection scheme of frame pointer generation. Previously
4800 if function did use local registers a frame pointer was generated,
4801 now a frame pointer is generated only if function has arguments
4802 (that need PLUSW2 register access), or has stack arguments, or the
4803 compiler is not instructed to omit the frame pointer,
4804 * (genEndFunction): before restoring local registers that were saved
4805 in the function preamble, also restore the registers that *might*
4806 have been allocated for stack access,
4807 * (genRet): removed some old comments,
4808 * (genCmp, the active (RN's) version): added a call to the
4809 pic16_genCmp_special function to perform the compare with a more
4810 robust and optimized way,
4811 * (genInline): a feature has been added in inline code generation,
4812 which allows a wildcard variable substitution when writing inline
4813 assembly. Code is incomplete and experimental therefore undocumented,
4814 * (genCast): changed order of aopOp for result and right to allow
4815 aopForSym to directly load the result if possible,
4816 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4817 perform an optimized compare on some selected special occasions,
4818 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4819 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4820 generate an IVT any more,
4821 * src/pic16/main.c (pic16_optionsTable): added command line option
4823 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4824 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4826 * src/pic16/NOTES: Raphael Neider added in list of active developers
4827 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4828 jumptable_end to prevent bug #,
4829 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4830 inCond and outCond fields,
4831 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4832 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4833 turn off register spilling,
4834 * (packRegsForOneUse): synced with other ports' versions although it
4835 is not used currently,
4836 * (pic16_packRegisters): added an optimization while reading
4837 structure bitfields, some registers may be saved (malloc code is
4838 decreased by 80 bytes)
4840 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4842 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4843 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4844 this can be optimized more?
4846 2005-03-10 Raphael Neider <rneider AT web.de>
4848 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4849 genNearPointerGet): (hopefully) fixed access to bitfields via
4850 pointers (p->bitN = x; and x = p->bitN; failed)
4852 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4893 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4895 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4896 to keep the correct label reference count when adding/removing references
4897 to labels. A peephole file using this is appended to patch #1144962.

5039 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5040 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5041 this might fix SIGSEGVs on MinGW...
5042 * src/SDCCopt.c (killDeadCode): restored original behaviour
5043 (volatile operands might get thrown away though)
5045 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5129 * (genUminus): rewritten to for efficiency
5130 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5131 used uninitialized in some cases)

5133 copy the third byte from the int -- now assumes 0x80 (data memory)
5134 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5135 operands (genAddLit expects the iCode's operands to swapped as
5136 well), fixed leftover bytes (crashed for short left operands)

5486 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5487 Now 4 algorithms for mcs51 jumptable generation are used:
5488 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5522 * added libc directory. The current version of LibC contains string
5523 functions, ctype functions and macros and some functions of the
5524 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5525 be extensively tested in the future. Standard disclaimer here.
5526 Library is not automatically build yet. But one can build it by

5538 * (pic16_storeForReturn): optimized return of 0,
5539 * (genCmp): experimental code for new genCmp which uses PIC18's
5540 special compare&skip instructions. Initial tests fail some times
5541 with variables grater than 1 byte in size, so new code is disabled,
5542 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5544 * (genCast): began a fix to optimize the casting of a bit to another
5545 bit, now assigning a bitfield to another bitfield will fail, sorry,

5554 and 1 for banking instruction,
5555 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5556 caused stop processing pCodes after a inline assembly block,

5559 registers when it shouldn't,
5560 * src/pic16/ralloc.c (allocReg): add preliminary support for
5561 supporting a limited set of temporary registers,
5563 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5566 genDataPointerSet): ensure assignments always copy in MSB to LSB
5568 (loadRegFromAop): recognize CLRH optimization,
5569 (genFunction): optimize RECEIVE iCodes in reentrant functions
5571 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5573 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8568 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8570 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8571 loaded with the linker search paths (-L arguments) and the libraries
8572 to be linked with the current source (-l arguments). Changes
8573 currently will affect only the pic16 port.
8574 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8575 include path the port specific paths and port specific libraries,
8576 * gplink command now contains the $3 argument,
8577 * src/pic16/device.h,
8578 * src/pic16/device.c,: structure PIC_device is made public and
8579 renamed to PIC16_device, the same for variable Pics which is renamed

8594 Documenting changes from previous commits.
8595 * configure.in (version 1.56),
8596 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8597 when generating output files to configure the pic16 library,
8598 but now I've commented it out, since gputils aren't installed in the
8599 SF compile farm, so library won't compile
8601 * device/lib/Makefile.in (version 1.56): initially I've added in
8602 target 'all' the prerequestive 'model-pic16' so it compiled the
8603 pic16 library, but now I've commented it out for the same reasons
8605 * added targets 'model-pic16' and 'objects-pic16' to compile the
8607 * added target 'port-specific-objects-pic16' to handle the
8608 generated libraries and copy them into the build/ directory
8609 * added target 'clean-intermediate-pic16' to clean intermediate
8610 files into pic16 directory
8611 * in target 'installdirs' added line to create directory pic16 in
8612 the installation path
8614 * device/include/Makefile.in (version 1.11): in target 'install'
8615 added lines to copy all header files to installation path,
8616 * in target 'installdirs' added line create directory for pic16
8617 headers in the installation path

8632 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8633 option so that it actually works. Made it specific to the z80, since
8634 the gbz80 doesn't have these kinds of I/O ports.
8636 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8638 * device/include/z180.h,

8662 via literal number. The symbol is placed in the corresponding
8663 position of the data ram
8664 * (pic16_dump_section): relocatable and absolute uninitialized
8665 data are now emitted in sorted order to reduce section naming,
8666 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8667 weren't marked as being in the access bank,
8669 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8671 Added portion of GNU PIC Library under the directory
8672 device/include/pic16 and device/lib/pic16. These files
8673 contain the declarations of SFRs for the PIC18Fxx2 devices.
8674 The directory is initialized via configure from toplevel.
8676 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8701 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8703 * doc/sdccman.lyx: Moved and added some sections, small changes
8704 all over. Telling LaTeX to be less strict with word spacing
8705 to better keep the right margin. Changed some notes about
8706 maintainance of the ports in section 3.2.1 - is it OK like this?
8708 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8710 SDCC source changes:
8711 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8860 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8862 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8863 (default behaviour).
8865 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8867 A python script to validate compiler diagnostic messages. It can be
8868 used to verify that sdcc complains about bad c source code and
8869 gives a good location of the error.
8870 * support/valdiag/Makefile,
8871 * support/valdiag/valdiag.py,
8872 * support/valdiag/tests/*

8887 * src/common.h: added ifndef/define/endif macros
8888 around the header file.
8889 Bug reported from Jesus Calvino-Fraga
8891 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8893 * sdcc.spec: updated
8894 * device/include/Makefile.in: don't install CVS directories
8895 * device/lib/Makefile.in: added removal of CVS directories after install
8896 * doc/Makefile: fixed install, added local_icons
8897 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8898 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8899 * src/ds390/gen.c (genRightShift): fixed bug #870788
8900 * src/SDCCast.c (decorateType): fixed bug #870781
8902 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8904 PIC16 port related changes:
8905 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8906 added variable stackPos,
8908 * gen.c: genCall, assignResultValue: added support for
8909 pushing/retrieving function parameters to/from stack,
8910 genFunction,genEndFunction: setup stack frame for the
8912 genAddrOf: will be changed according to bug 863624
8914 * added files genutils.c and genutils.h which contain gen*
8915 debugged and optimised functions extracted from gen.c
8917 * glue.c: added variable 'externs' which holds extern symbols,
8918 pic16emitRegularMap: is modified to properly handle relocatable
8919 symbols under the new scheme,
8920 pic16createInterruptVect: is modified
8921 pic16printPublics: is modified to emit 'global' assembler directives,
8922 added pic16_printExterns to print extern symbols,
8923 pic16glue: initializes stack/frame pointer in the beginning of
8924 the assembly output. Temporary hack, will be corrected later,
8925 because gplink yet does not support stack and SDCC does not
8926 yet support a type of crt0.o object to create the final binary.
8928 * Removed many lines that contain 8051 legacy code.
8929 * The code is finally placed under a 'code' directive.
8930 * Added port specific options.
8932 * _process_pragma: simplified since now we do not need *special*
8933 include file to define SFR registers. But a separate header
8934 will be needed. This will be developed later.
8935 * _pic16_parseOptions: added, parses port specific options:
8936 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8937 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8938 --preplace-udata-with=
8940 * _pic16_setDefaultOptions: modified to initialize section names,
8941 but hack is temporarly out of order since it needs improvement.
8942 * _pic16_genAssemblerPreamble: configuration words are emitted by
8943 their address instead of their name. This part is incomplete and
8944 supports only the 18Fxx2 devices. Other devices will emit an error
8945 during assembly since they do not contain the same set of config
8947 * _pic16_genIVT: is modified,
8949 * pcode.c: added definitions for some hardware registers that are needed
8951 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8952 All PCI entries are updated. Now LFSR is supported.
8953 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8954 * added pic16_newpCodeOpLit2 to support instructions with
8955 two literal arguments
8956 * pic16_pCode2str: corrected code that emits assembler instructions
8957 with two literal operands and those that have an access bit modifier
8958 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8959 this fixes a bug which caused some labels to be lost, when an
8960 assembler directive was added, i.e. banksel,
8961 * pic16_FixRegisterBanking: improved logic that causes the insertion
8963 * InlineFunction: functions that are called once, are not any more
8964 inlined. This can be a port option in the future,
8966 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8968 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8969 hold the corresponding uninitialized symbols,
8970 * pic16_allocProcessorRegister: registers have explicit marked the
8972 * pic16_allocInternalRegister: registers are explicit marked as
8974 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8975 processing list, so bit registers were lost,
8978 * ralloc.h: added field 'accessBank' and original symbol operand
8979 in register definition,
8980 * removed the field isMapped from register definition,
8982 ** Several functions have been removed from various sources:
8983 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8984 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8985 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8986 pic16_assignRelocatableRegisters
8988 ** others have been introduced:
8989 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8990 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8992 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8994 * support/scripts/inc2h.pl: changed definition of BIT_AT
8995 to emit 'sbit at' instead of 'bit at'. This was a request.
8997 PIC16 port related preliminary changes:
8998 * gen.c: prefixed function popRegFromString with
8999 pic16_ and all references to it corrected
9000 * pcode.c: all pic16_pc_* hardware registers prefixed
9001 with underscore (_),
9002 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9003 * ralloc.c: newReg(): when register is REG_SFR then
9004 set address to rIdx,
9005 pic16_allocProcessorRegister(): marks register wasUsed=0
9006 pic16_writeUsedRegs(): added a call to assign processor
9007 registers via pic16_assignFixedRegisters
9009 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9011 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9012 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9013 variables in unused register banks. Also the SSEG is placed
9014 wherever there is enough space for it, and IDATA can be anywhere
9015 in internal RAM. For now compile using -Wl-Y[stack_size].
9016 The mem file is different for this option as well, since it
9017 makes no sense of talking about DSEG lenght.
9019 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9021 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9022 in certain cases, e.g. when ROM assignment, patch provided
9023 from Albert den Haan.
9025 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9168 * src/mcs51/peephole.def,
9169 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9170 (allows non-interrupt and interrupt code to safely compete for a resource

9931 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9933 Fixed bug #621531 (const & volatile confusion in the type chain).
9934 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

10014 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10015 iCode properly now. Use getSize instead of nRegs since a & b

10030 copied from genNearPointerSet()
10031 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10032 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10033 If they pop r0/r1 they must be called in the opposite order than aopOp().
10034 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10035 (resp. --stack-auto), prepared for --xstack

10048 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10049 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10050 type for bits was changed. It resulted in bit variables becoming
10051 global, which is not permitted in PIC 14 assembly output.
10053 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10055 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10066 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10068 A few small changes that speed up the peephole optimizer.
10072 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10074 Try to make the peephole optimizer smarter by maintaining
10075 an association between the assembly source code and the
10076 iCodes that originated them. Put this information to use
10077 with a new peephole rule condition "notVolatile" so that
10078 the rules can be aggressive yet still safe.
10083 * src/mcs51/peeph.def
10085 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10089 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10090 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10091 if the left or right operand symbols have the accuse flag set.
10093 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10095 Changed the type of the result of the ! (NOT) operator to char;
10096 previously it returned the same type as the source. This allows
10097 us to eliminate all the genFloatNot functions (all of its target
10098 implementations were very buggy) since !float can use the same
10101 * src/SDCCicode.c (ast2iCode): ! returns char

10110 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10111 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10112 during interrupts. Ensure WSAVE is located at a shared bank address.
10113 2. Fixed page selection in some places
10114 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10115 the registers name strings.
10116 4. Fixed "signed / unsigned compare" compiler warnings.
10117 5. The PIC port manages its own allocation of the general purpose
10118 registers, but makes no attempt to reuse them. As a result when
10119 compiling it soon runs out of general purpose registers. Some
10120 additional code was added to the files pcode.c and device.c to walk
10121 through the function call tree and rename the registers so that they
10131 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10132 genPlus() & genMinus() when the result is the same as left or right
10134 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10138 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10140 Made bitfield a distinct type from bit so that bitfields
10141 convert as per ANSI C and bits retain their traditional
10142 boolean style behaviour. Implemented bitfield support in
10150 * src/ds390/gen.c: bit v bitfield split
10151 * src/z80/gen.c: New support for bitfields
10152 * support/regression/tests/bitfields.c: reenabled z80,
10155 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10157 Rules 246.x, 247.x relate to bitfields, the others speed up
10158 access to xdata mapped I/O devices.
10160 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10162 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10164 Cleaned up genPackBits and genUnpackBits and added two helper
10165 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10166 for literal assignments in genPackBits (thanks to Frieder for
10172 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10174 Fixed bug #748310 (pointer to function type mishandled when the
10175 function name is omitted). Also fixed a SIGSEGV when a function
10176 attribute (reentrant, etc) is used on a non-function or on a
10177 function but misplaced before the parameter list.
10179 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10181 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10182 * support/Util/SDCCerr.h,

10187 Fixed bug #787649 by anonymous
10188 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10189 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10191 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10193 Fixed numerous bitfield problems.
10195 * src/SDCC.y: More bitfield related error checking

10206 Made the constant following the "interrupt" keyword optional. If
10207 omitted, the function will not automatically be given an entry
10208 in the interrupt vector table (similar to #pragma NOIV, but
10209 less syntacticly kludgy). The interrupt number is also now
10210 range checked. Also fixed a bug in the high order bit example

10231 unsigned, but are signed by default
10232 * src/SDCCval.c (constVal): rearranged
10233 * src/SDCCval.c (valMod): preliminary fix

10277 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10278 * src/SDCCval.c (valDiv, valMod): fixed signdness

10728 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10730 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10731 it can be defined with CFLAGS when running configure
10732 * src/SDCCmain.c: fixed compiling + linking with object files
10734 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10736 * configure.in: configure for pic16 port,
10737 added --disable-pic16-port
10738 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10739 * src/SDCCmain.c: linkOptions is changed to set *,
10740 added if/endif conditional macros to remove options help
10741 messages from optionsTable when a port is not configured, added
10742 support for the PIc16 port in the ports table, when executing
10743 the compiler with no port specified on command line, a default
10744 port is selected with the new macro DEFAULT_PORT which is
10745 defined in port.h, in setDefaultOptions() linkOptions is removed
10746 from initialization assignment, since now it is a set,
10747 parseCmdLine uses setParseWithComma for linkOptions, in
10748 linkEdit() linkOptions are accessed with new function indexSet()
10749 which returns the i'th item of a set variable. See SDCCset.c, in
10750 linkEdit() when calling buildCmdLine(), added linkOptions as
10751 last argument. Now users can pass arguments to gplink via the
10752 -Wl option, main() uses pic16glue() to glue up pic16 programs
10753 * src/SDCCpeeph.c: various changes to support pic16
10754 * src/SDCCset.c: added function void *indexSet(set *, int) to
10755 return the i'th item of the set

10762 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
10764 * src/pic16/glue.c: commented out some error producing lines
10765 * src/pic16/main.c: __config directives are commented out to stop
10766 gpasm complaining and test the linkage with gplink, _linkCmd and
10767 _asmCmd changed to be more gplink and gpasm friendly
10768 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10769 produced an error when parsed, peep rule 12 is added to utilize
10770 movff, but it is commented out since the pCode does not support
10771 yet a command with 2 address arguments
10773 2003-05-18 <johan AT balder>
10775 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11823 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11824 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11831 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11833 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11834 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11836 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11838 * in /sdcc/as/mcs51/ changed these files in order to create an
11839 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11840 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11841 following files to include the previous two files: aslink.dsp,
11842 Makefile.aslink, Makefile.bcc, and Makefile.in.
11844 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11845 .adb instead of .cdb
11847 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11849 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11850 value from option --iram-size.
11852 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11854 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11857 2002-09-18 <wiml AT hhhh.org>
11859 * SDCClrange.h: exposed setFromRange() and setToRange()
11860 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11861 packRegsForAccUse() (bug 542397)
11862 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11863 multiple times and emitting the fetch operations more than once
11864 added aopGetUsesAcc() function to allow binary operators to
11865 fetch their operands in the correct order; made genMinus() emit
11866 compact code for X = LITERAL - Y
11868 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11869 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11870 sprintf() in line 1267.
11872 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11873 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11876 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11877 Changes to aslink (All the changes are marked with 'JCF'):
11879 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11882 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11883 area BSEG. Also moves, if possible, the DATA area down into the internal
11884 ram so more space is available.
11886 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11889 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11890 not bytes. Function summary() which creates a memory usage summary
11891 file with extension .mem. Reports of overlaping stack and small stack
11892 size. If the space for the stack is less than 16 bytes aslink trows a
11895 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11896 the 8051. Option 'y' for memory summary output file.
11898 Changes to sdcc (All the changes are marked with 'JCF'):
11900 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11902 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11903 overlaying area for it (uses RegBankUsed[4]).
11905 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11906 bank zero as used by default. By default aslink locates the stack
11907 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11908 the creation of the .mem file. Delegates the allocation of data area
11909 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11910 the begining of the stack area to aslink.
11912 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11913 glue() in SDCCglue.c creates an area for it.
11915 2002-09-03 Borut Razem <borut.razem AT siol.net>
11916 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11917 sdcc/src/pic/glue.c:
11918 introduced atexit() handler for teporay files removal in case of
11919 errors, assertions, ...
11921 2002-08-29 Borut Razem <borut.razem AT siol.net>
11922 * sdcc/support/cpp2/auto-host_vc_in.h:
11923 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11924 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11925 Maybe there is a similar problem with BORLANDC? It should be checked!
11927 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11928 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11929 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11930 was not executed, and the compiler (cl) launched a warning:
11931 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11933 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11934 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11936 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11937 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11939 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11940 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11941 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11942 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11943 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11944 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11945 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11946 - added Release configuration in VS projects
11947 - review of compiler an linker options
11948 - VC .exe files are generated in bin_vc directory, not to interfere
11949 with binaries generated from other projects (cygwin, mingw, bcc ...)
11951 * sdcc/src/yacc.dsp: added
11953 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11954 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11955 and insert the version number definitions from .version
11957 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11959 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11960 added - genarate auto-host.h using auto-host_vc_in.h as template
11963 removed from CVS, generated automatically
11965 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11966 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11968 2002-08-11 Borut Razem <borut.razem AT siol.net>
11969 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11971 2002-08-10 Borut Razem <borut.razem AT siol.net>
11972 * src/SDCCmain.c (main):
11973 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11974 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11975 The consequence was that some temporary files were not removed.
11978 unification of code in functions tempfilename() and tempfile():
11979 function tempnam() is defined in Visual Studio 6.0 and .NET

12187 Previous fix was not good. basic blocks that have "break" or "return" are
12188 not really partof a loop , but live ranges used in these blocks should
