1968 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1970 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1971 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1973 One basic decision: e.g. src/clean.mk includes further files. In order
1974 to make this work there are two solutions:
1975 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1976 run configure on them. This way they can use
1977 'include $(srcdir)/port-clean.mk'
1978 - always include clean.mk by the Makefile at the same level. To avoid
1979 that `make clean` tries to include and build Makefile.dep the
1980 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1981 implemented, because now even `make uninstall` doesn't create
1982 Makefile.in. clean.mk could be eliminated by pasting it in
1985 * debugger/mcs51/Makefile.in: build own objects from library sources
1986 (SLIB, SDCC) in current directory
1988 * configure, configure.in: renamed --disable-device-lib-build in
1989 --disable-device-lib; added --enable-doc, the required tools are
1990 searched by configure; added result message; the toolchain for the
1991 belonging ports are now only built, if the port is enabled.
1993 * support/regression/*: all output is written in directory gen, because
1994 the fwk and ports directories don't livet in the build tree using vpath
1996 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1997 --disable-device-lib, added --enable-doc, added section VPATH
1999 * sim/ucsim/configure.in,
2000 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2001 z80 are enabled by default
2003 2006-04-24 Raphael Neider <rneider AT web.de>
2005 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2006 to config word, "pic14_"-prefixed some extern functions
2007 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2008 config word has been found
2009 * src/pic/device.h: added prototypes
2010 * src/pic/pcode.c: added "pic14_"-prefix where needed
2011 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2013 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2251 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2253 * src/mcs51/gen.c (genCall): fixed bug 1457608
2255 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2257 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

2260 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2262 * src/SDCCpeeph.c (operandsLiteral): new, added,

2274 implemented patch 1120823 Thanks to Willy De la Court (normal
2275 interrupts need an interrupt number now if they are made critical),
2276 and enabled nesting of critical functions though not for gbz80
2277 (genCritical, genEndCritical): added functions
2278 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2279 * src/z80/mappings.i: added "ei" to all mappings
2281 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2283 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2284 submitted by the Debian SDCC maintainer Aurelien Jarno:
2285 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2286 archive with gcc 4.1 on mips and wrote the patch"
2288 2006-03-16 Raphael Neider <rneider AT web.de>
2290 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2291 the left operand is shorter than the result (c* = lit-c* + int),
2293 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2296 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2298 * src/.version: increased version number to 2.5.5
2299 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2300 linking is done manually in pic16 port's _linkEdit,
2301 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2302 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2303 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2304 allocate asmop as AOP_ACC,
2305 (aopForRemat): added parameter 'bool result' in function declaration,
2306 (pic16_aopGet): return AOP_ACC when accessing WREG,
2307 (pic16_popGetTempReg): minor modification,
2308 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2309 'pic16_allocWithIdx',
2310 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2311 calling function in absolute addresses,
2312 (genAssign): take into account AOP_ACC asmop,
2313 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2314 * src/pic16/pcoderegs.c: some debug functions and lines added,

2316 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2318 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2319 call to allocReg, not by manually allocating a new one,
2320 (pic16_assignRegisters): now before going through the register
2321 allocating functions mark all registers as free. This eliminates some
2322 side effects resulting from peephole parser done earlier in the backbone
2324 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2326 * src/SDCCicode.c (geniCodeLogic),

2345 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2346 (aopForSym, aopOp): increment asmop.allocated if reused,
2347 (freeAsmop): decrement asmop.allocated and check for zero instead of
2349 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2350 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2351 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2374 2006-03-06 Borut Razem <borut.razem AT siol.net>
2376 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2377 made the linker quiet
2379 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2381 * src/pic16/gen.c (genPcall): fixed bug #1443644
2382 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2383 which dumps before the function entry point a data byte which represents
2384 the number of the local variables used by the specified function, added
2385 'xinst' for initial support for Extended Instruction Support,
2386 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2387 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2388 port->fun_prefix anymore (may change later),
2389 (genFunction, genEndFunction): do not store/restore local registers for
2390 _main (this should take care the --main-return command line option in
2392 (genOr): removed some legacy pic-port instructions,
2393 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2394 performing operations with SFR's causes data to be written more than
2395 once to each SFR. Perhaps SFRs should be handled in special cases...
2396 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2398 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2399 into account for stack starting position,
2400 (struct OPTIONS pic16_optionsTable): added command line argument
2401 --extended or -y for Extended Instruction Support,
2402 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2403 (deassignLRs): *** perhaps the most important change, old 'for' code
2404 (commented out for reference), didn't account for some registers which
2405 were left marked 'not free' after a pointer operation. The change
2406 reduces register usage a lot in some cases
2408 2006-03-04 Borut Razem <borut.razem AT siol.net>
2410 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4703 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4705 * src/port.h (struct PORT),
4706 * src/avr/ralloc.c (avr_assignRegisters),
4708 * src/ds390/ralloc.c (ds390_assignRegisters),
4710 * src/hc08/ralloc.c (hc08_assignRegisters),

4731 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4732 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4733 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4734 immedDom() returning wrong block; probably fixes bug #1160833)
4736 2005-03-20 Borut Razem <borut.razem AT siol.net>
4738 * support/scripts/inc2h.pl: WIN32 port
4740 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4742 * device/lib/makefile.in: added abs.c and labs.c
4744 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4746 * device/include/stdint.h: added
4747 * device/lib/abs.c: added
4748 * device/lib/labs.c: added
4749 * device/include/stdlib.h: added abs() and labs() prototypes
4750 * device/lib/libsdcc.lib: added abs and labs
4751 * device/include/float.h,
4752 * device/lib/_fsmul.c,
4753 * device/lib/printf_fast.c,
4754 * device/lib/printf_tiny.c: updated comments
4756 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4758 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4761 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4763 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4764 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4766 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4768 * device/lib/printf_large.c: removed inline assembly for portability and
4769 readability. Use printf_fast if speed or size are more important.
4770 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4771 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4773 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4775 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4776 prevent compiler warning
4778 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4780 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4781 moved to level 0 and declared as static. Also they are explicit
4782 placed in access bank. This was necessery because some times they
4783 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4784 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4785 optimizations. Currently only compare to unsigned char is implemented,
4786 * src/pic16/gen.c: added fReturnIdx array,
4787 * (struct resolvedIfx) is moved to gen.h and made public,
4788 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4789 * (aopForSym): added an optimization to directly store in stack of
4790 the operand of a SEND iCode,
4791 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4792 but as registers instead (AOP_REG) using the fReturnIdx array,
4793 * (pic16_freeAsmop): remove the freed register from the
4794 _G.sregsAlloc field,
4795 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4796 a compare of 'WREG',
4797 * (pic16_popGetTempRegCond): changed function prototype, now
4798 function takes also a bitVector argument v which holds the current
4799 set of registers that are allocated for stack access by aopForSym,
4800 registers allocated in aopForSym for accessing stack symbols are not
4801 any more part of the functions usedRegs field,
4802 * (genCall): some times aopOp is called for a stack variable to be
4803 send, aopForSym might perform the push, if this is true make sure
4804 that genCall doesn't push the variable twice by testing _G.resDirect,
4805 * (genFunction): changed testing for unspecified interrupt number
4806 from 256 to INTNO_UNSPEC,
4807 * modified selection scheme of frame pointer generation. Previously
4808 if function did use local registers a frame pointer was generated,
4809 now a frame pointer is generated only if function has arguments
4810 (that need PLUSW2 register access), or has stack arguments, or the
4811 compiler is not instructed to omit the frame pointer,
4812 * (genEndFunction): before restoring local registers that were saved
4813 in the function preamble, also restore the registers that *might*
4814 have been allocated for stack access,
4815 * (genRet): removed some old comments,
4816 * (genCmp, the active (RN's) version): added a call to the
4817 pic16_genCmp_special function to perform the compare with a more
4818 robust and optimized way,
4819 * (genInline): a feature has been added in inline code generation,
4820 which allows a wildcard variable substitution when writing inline
4821 assembly. Code is incomplete and experimental therefore undocumented,
4822 * (genCast): changed order of aopOp for result and right to allow
4823 aopForSym to directly load the result if possible,
4824 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4825 perform an optimized compare on some selected special occasions,
4826 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4827 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4828 generate an IVT any more,
4829 * src/pic16/main.c (pic16_optionsTable): added command line option
4831 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4832 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4834 * src/pic16/NOTES: Raphael Neider added in list of active developers
4835 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4836 jumptable_end to prevent bug #,
4837 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4838 inCond and outCond fields,
4839 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4840 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4841 turn off register spilling,
4842 * (packRegsForOneUse): synced with other ports' versions although it
4843 is not used currently,
4844 * (pic16_packRegisters): added an optimization while reading
4845 structure bitfields, some registers may be saved (malloc code is
4846 decreased by 80 bytes)
4848 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4850 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4851 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4852 this can be optimized more?
4854 2005-03-10 Raphael Neider <rneider AT web.de>
4856 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4857 genNearPointerGet): (hopefully) fixed access to bitfields via
4858 pointers (p->bitN = x; and x = p->bitN; failed)
4860 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4862 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4901 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4903 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4904 to keep the correct label reference count when adding/removing references
4905 to labels. A peephole file using this is appended to patch #1144962.

5047 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5048 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5049 this might fix SIGSEGVs on MinGW...
5050 * src/SDCCopt.c (killDeadCode): restored original behaviour
5051 (volatile operands might get thrown away though)
5053 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5137 * (genUminus): rewritten to for efficiency
5138 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5139 used uninitialized in some cases)
5140 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
5141 copy the third byte from the int -- now assumes 0x80 (data memory)
5142 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5143 operands (genAddLit expects the iCode's operands to swapped as
5144 well), fixed leftover bytes (crashed for short left operands)

5493 generated for switch statements. For now you need to set the
5494 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5495 Now 4 algorithms for mcs51 jumptable generation are used:
5496 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5530 * added libc directory. The current version of LibC contains string
5531 functions, ctype functions and macros and some functions of the
5532 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5533 be extensively tested in the future. Standard disclaimer here.
5534 Library is not automatically build yet. But one can build it by

5546 * (pic16_storeForReturn): optimized return of 0,
5547 * (genCmp): experimental code for new genCmp which uses PIC18's
5548 special compare&skip instructions. Initial tests fail some times
5549 with variables grater than 1 byte in size, so new code is disabled,
5550 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5552 * (genCast): began a fix to optimize the casting of a bit to another
5553 bit, now assigning a bitfield to another bitfield will fail, sorry,

5562 and 1 for banking instruction,
5563 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5564 caused stop processing pCodes after a inline assembly block,
5565 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5567 registers when it shouldn't,
5568 * src/pic16/ralloc.c (allocReg): add preliminary support for
5569 supporting a limited set of temporary registers,
5571 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5573 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

8576 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8578 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8579 loaded with the linker search paths (-L arguments) and the libraries
8580 to be linked with the current source (-l arguments). Changes
8581 currently will affect only the pic16 port.
8582 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8583 include path the port specific paths and port specific libraries,
8584 * gplink command now contains the $3 argument,
8585 * src/pic16/device.h,
8586 * src/pic16/device.c,: structure PIC_device is made public and
8587 renamed to PIC16_device, the same for variable Pics which is renamed

8602 Documenting changes from previous commits.
8603 * configure.in (version 1.56),
8604 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8605 when generating output files to configure the pic16 library,
8606 but now I've commented it out, since gputils aren't installed in the
8607 SF compile farm, so library won't compile
8609 * device/lib/Makefile.in (version 1.56): initially I've added in
8610 target 'all' the prerequestive 'model-pic16' so it compiled the
8611 pic16 library, but now I've commented it out for the same reasons
8613 * added targets 'model-pic16' and 'objects-pic16' to compile the
8615 * added target 'port-specific-objects-pic16' to handle the
8616 generated libraries and copy them into the build/ directory
8617 * added target 'clean-intermediate-pic16' to clean intermediate
8618 files into pic16 directory
8619 * in target 'installdirs' added line to create directory pic16 in
8620 the installation path
8622 * device/include/Makefile.in (version 1.11): in target 'install'
8623 added lines to copy all header files to installation path,
8624 * in target 'installdirs' added line create directory for pic16
8625 headers in the installation path

8640 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8641 option so that it actually works. Made it specific to the z80, since
8642 the gbz80 doesn't have these kinds of I/O ports.
8644 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8646 * device/include/z180.h,

8668 Mainly changes to support compilation of the device libraries
8669 * src/pic16/device.c: stack is allocated via symbol and not
8670 via literal number. The symbol is placed in the corresponding
8671 position of the data ram
8672 * (pic16_dump_section): relocatable and absolute uninitialized
8673 data are now emitted in sorted order to reduce section naming,
8674 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8675 weren't marked as being in the access bank,
8677 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8679 Added portion of GNU PIC Library under the directory
8680 device/include/pic16 and device/lib/pic16. These files
8681 contain the declarations of SFRs for the PIC18Fxx2 devices.
8682 The directory is initialized via configure from toplevel.
8684 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8711 * doc/sdccman.lyx: Moved and added some sections, small changes
8712 all over. Telling LaTeX to be less strict with word spacing
8713 to better keep the right margin. Changed some notes about
8714 maintainance of the ports in section 3.2.1 - is it OK like this?
8716 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8851 include information about variables allocated to the overlay
8854 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8856 * as/mcs51/lkmain.c: Help about -Y option

8868 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8870 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8871 (default behaviour).
8873 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8875 A python script to validate compiler diagnostic messages. It can be
8876 used to verify that sdcc complains about bad c source code and
8877 gives a good location of the error.
8878 * support/valdiag/Makefile,
8879 * support/valdiag/valdiag.py,
8880 * support/valdiag/tests/*

8897 Bug reported from Jesus Calvino-Fraga
8899 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8901 * sdcc.spec: updated
8902 * device/include/Makefile.in: don't install CVS directories
8903 * device/lib/Makefile.in: added removal of CVS directories after install
8904 * doc/Makefile: fixed install, added local_icons
8905 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8906 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8907 * src/ds390/gen.c (genRightShift): fixed bug #870788
8908 * src/SDCCast.c (decorateType): fixed bug #870781
8910 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8912 PIC16 port related changes:
8913 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8914 added variable stackPos,
8916 * gen.c: genCall, assignResultValue: added support for
8917 pushing/retrieving function parameters to/from stack,
8918 genFunction,genEndFunction: setup stack frame for the
8920 genAddrOf: will be changed according to bug 863624
8922 * added files genutils.c and genutils.h which contain gen*
8923 debugged and optimised functions extracted from gen.c
8925 * glue.c: added variable 'externs' which holds extern symbols,
8926 pic16emitRegularMap: is modified to properly handle relocatable
8927 symbols under the new scheme,
8928 pic16createInterruptVect: is modified
8929 pic16printPublics: is modified to emit 'global' assembler directives,
8930 added pic16_printExterns to print extern symbols,
8931 pic16glue: initializes stack/frame pointer in the beginning of
8932 the assembly output. Temporary hack, will be corrected later,
8933 because gplink yet does not support stack and SDCC does not
8934 yet support a type of crt0.o object to create the final binary.
8936 * Removed many lines that contain 8051 legacy code.
8937 * The code is finally placed under a 'code' directive.
8938 * Added port specific options.
8940 * _process_pragma: simplified since now we do not need *special*
8941 include file to define SFR registers. But a separate header
8942 will be needed. This will be developed later.
8943 * _pic16_parseOptions: added, parses port specific options:
8944 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8945 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8946 --preplace-udata-with=
8948 * _pic16_setDefaultOptions: modified to initialize section names,
8949 but hack is temporarly out of order since it needs improvement.
8950 * _pic16_genAssemblerPreamble: configuration words are emitted by
8951 their address instead of their name. This part is incomplete and
8952 supports only the 18Fxx2 devices. Other devices will emit an error
8953 during assembly since they do not contain the same set of config
8955 * _pic16_genIVT: is modified,
8957 * pcode.c: added definitions for some hardware registers that are needed
8959 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8960 All PCI entries are updated. Now LFSR is supported.
8961 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8962 * added pic16_newpCodeOpLit2 to support instructions with
8963 two literal arguments
8964 * pic16_pCode2str: corrected code that emits assembler instructions
8965 with two literal operands and those that have an access bit modifier
8966 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8967 this fixes a bug which caused some labels to be lost, when an
8968 assembler directive was added, i.e. banksel,
8969 * pic16_FixRegisterBanking: improved logic that causes the insertion
8971 * InlineFunction: functions that are called once, are not any more
8972 inlined. This can be a port option in the future,
8974 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8976 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8977 hold the corresponding uninitialized symbols,
8978 * pic16_allocProcessorRegister: registers have explicit marked the
8980 * pic16_allocInternalRegister: registers are explicit marked as
8982 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8983 processing list, so bit registers were lost,
8986 * ralloc.h: added field 'accessBank' and original symbol operand
8987 in register definition,
8988 * removed the field isMapped from register definition,
8990 ** Several functions have been removed from various sources:
8991 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8992 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8993 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8994 pic16_assignRelocatableRegisters
8996 ** others have been introduced:
8997 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8998 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9000 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9002 * support/scripts/inc2h.pl: changed definition of BIT_AT
9003 to emit 'sbit at' instead of 'bit at'. This was a request.
9005 PIC16 port related preliminary changes:
9006 * gen.c: prefixed function popRegFromString with
9007 pic16_ and all references to it corrected
9008 * pcode.c: all pic16_pc_* hardware registers prefixed
9009 with underscore (_),
9010 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9011 * ralloc.c: newReg(): when register is REG_SFR then
9012 set address to rIdx,
9013 pic16_allocProcessorRegister(): marks register wasUsed=0
9014 pic16_writeUsedRegs(): added a call to assign processor
9015 registers via pic16_assignFixedRegisters
9017 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9019 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9020 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9021 variables in unused register banks. Also the SSEG is placed
9022 wherever there is enough space for it, and IDATA can be anywhere
9023 in internal RAM. For now compile using -Wl-Y[stack_size].
9024 The mem file is different for this option as well, since it
9025 makes no sense of talking about DSEG lenght.
9027 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9029 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9030 in certain cases, e.g. when ROM assignment, patch provided
9031 from Albert den Haan.
9033 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10056 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10057 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10058 type for bits was changed. It resulted in bit variables becoming
10059 global, which is not permitted in PIC 14 assembly output.
10061 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10063 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10076 A few small changes that speed up the peephole optimizer.
10080 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10082 Try to make the peephole optimizer smarter by maintaining
10083 an association between the assembly source code and the
10084 iCodes that originated them. Put this information to use
10085 with a new peephole rule condition "notVolatile" so that
10086 the rules can be aggressive yet still safe.
10091 * src/mcs51/peeph.def
10093 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10097 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10098 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10099 if the left or right operand symbols have the accuse flag set.
10101 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10103 Changed the type of the result of the ! (NOT) operator to char;
10104 previously it returned the same type as the source. This allows
10105 us to eliminate all the genFloatNot functions (all of its target
10106 implementations were very buggy) since !float can use the same

10118 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10119 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10120 during interrupts. Ensure WSAVE is located at a shared bank address.
10121 2. Fixed page selection in some places
10122 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10123 the registers name strings.
10124 4. Fixed "signed / unsigned compare" compiler warnings.
10125 5. The PIC port manages its own allocation of the general purpose
10126 registers, but makes no attempt to reuse them. As a result when
10127 compiling it soon runs out of general purpose registers. Some
10128 additional code was added to the files pcode.c and device.c to walk
10129 through the function call tree and rename the registers so that they
10139 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10140 genPlus() & genMinus() when the result is the same as left or right

10146 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10148 Made bitfield a distinct type from bit so that bitfields
10149 convert as per ANSI C and bits retain their traditional
10150 boolean style behaviour. Implemented bitfield support in
10158 * src/ds390/gen.c: bit v bitfield split
10159 * src/z80/gen.c: New support for bitfields
10160 * support/regression/tests/bitfields.c: reenabled z80,
10163 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10165 Rules 246.x, 247.x relate to bitfields, the others speed up
10166 access to xdata mapped I/O devices.
10168 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10170 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10172 Cleaned up genPackBits and genUnpackBits and added two helper

10182 Fixed bug #748310 (pointer to function type mishandled when the
10183 function name is omitted). Also fixed a SIGSEGV when a function
10184 attribute (reentrant, etc) is used on a non-function or on a
10185 function but misplaced before the parameter list.
10187 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10189 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10190 * support/Util/SDCCerr.h,

10199 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10201 Fixed numerous bitfield problems.
10203 * src/SDCC.y: More bitfield related error checking

10214 Made the constant following the "interrupt" keyword optional. If
10215 omitted, the function will not automatically be given an entry
10216 in the interrupt vector table (similar to #pragma NOIV, but
10217 less syntacticly kludgy). The interrupt number is also now
10218 range checked. Also fixed a bug in the high order bit example

10239 unsigned, but are signed by default
10240 * src/SDCCval.c (constVal): rearranged
10241 * src/SDCCval.c (valMod): preliminary fix

10284 constants are unsigned; added recognition of "u" flag for unsigned
10285 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10286 * src/SDCCval.c (valDiv, valMod): fixed signdness
10287 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

10736 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10738 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10739 it can be defined with CFLAGS when running configure
10740 * src/SDCCmain.c: fixed compiling + linking with object files
10742 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10744 * configure.in: configure for pic16 port,
10745 added --disable-pic16-port
10746 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10747 * src/SDCCmain.c: linkOptions is changed to set *,
10748 added if/endif conditional macros to remove options help
10749 messages from optionsTable when a port is not configured, added
10750 support for the PIc16 port in the ports table, when executing
10751 the compiler with no port specified on command line, a default
10752 port is selected with the new macro DEFAULT_PORT which is
10753 defined in port.h, in setDefaultOptions() linkOptions is removed
10754 from initialization assignment, since now it is a set,
10755 parseCmdLine uses setParseWithComma for linkOptions, in
10756 linkEdit() linkOptions are accessed with new function indexSet()
10757 which returns the i'th item of a set variable. See SDCCset.c, in
10758 linkEdit() when calling buildCmdLine(), added linkOptions as
10759 last argument. Now users can pass arguments to gplink via the
10760 -Wl option, main() uses pic16glue() to glue up pic16 programs
10761 * src/SDCCpeeph.c: various changes to support pic16
10762 * src/SDCCset.c: added function void *indexSet(set *, int) to

10772 * src/pic16/glue.c: commented out some error producing lines
10773 * src/pic16/main.c: __config directives are commented out to stop
10774 gpasm complaining and test the linkage with gplink, _linkCmd and
10775 _asmCmd changed to be more gplink and gpasm friendly
10776 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10777 produced an error when parsed, peep rule 12 is added to utilize
10778 movff, but it is commented out since the pCode does not support
10779 yet a command with 2 address arguments

11844 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11846 * in /sdcc/as/mcs51/ changed these files in order to create an
11847 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11848 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11849 following files to include the previous two files: aslink.dsp,
11850 Makefile.aslink, Makefile.bcc, and Makefile.in.
11852 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11853 .adb instead of .cdb
11855 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11857 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11858 value from option --iram-size.
11860 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11862 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11865 2002-09-18 <wiml AT hhhh.org>
11867 * SDCClrange.h: exposed setFromRange() and setToRange()
11868 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11869 packRegsForAccUse() (bug 542397)
11870 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11871 multiple times and emitting the fetch operations more than once
11872 added aopGetUsesAcc() function to allow binary operators to
11873 fetch their operands in the correct order; made genMinus() emit
11874 compact code for X = LITERAL - Y
11876 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11877 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11878 sprintf() in line 1267.
11880 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11881 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11884 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11885 Changes to aslink (All the changes are marked with 'JCF'):
11887 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11890 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11891 area BSEG. Also moves, if possible, the DATA area down into the internal
11892 ram so more space is available.
11894 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11897 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11898 not bytes. Function summary() which creates a memory usage summary
11899 file with extension .mem. Reports of overlaping stack and small stack
11900 size. If the space for the stack is less than 16 bytes aslink trows a
11903 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11904 the 8051. Option 'y' for memory summary output file.
11906 Changes to sdcc (All the changes are marked with 'JCF'):
11908 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11910 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11911 overlaying area for it (uses RegBankUsed[4]).
11913 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11914 bank zero as used by default. By default aslink locates the stack
11915 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11916 the creation of the .mem file. Delegates the allocation of data area
11917 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11918 the begining of the stack area to aslink.
11920 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11921 glue() in SDCCglue.c creates an area for it.
11923 2002-09-03 Borut Razem <borut.razem AT siol.net>
11924 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11925 sdcc/src/pic/glue.c:
11926 introduced atexit() handler for teporay files removal in case of
11927 errors, assertions, ...
11929 2002-08-29 Borut Razem <borut.razem AT siol.net>
11930 * sdcc/support/cpp2/auto-host_vc_in.h:
11931 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11932 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11933 Maybe there is a similar problem with BORLANDC? It should be checked!
11935 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11936 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11937 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11938 was not executed, and the compiler (cl) launched a warning:
11939 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11941 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11942 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11971 removed from CVS, generated automatically
11973 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11974 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11976 2002-08-11 Borut Razem <borut.razem AT siol.net>
11977 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)

11980 * src/SDCCmain.c (main):
11981 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11982 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11983 The consequence was that some temporary files were not removed.
11986 unification of code in functions tempfilename() and tempfile():
11987 function tempnam() is defined in Visual Studio 6.0 and .NET
11989 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11991 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11992 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11993 - removed compiler command line option /WX: Treats all warnings as errors
11994 - update a list of source files, included into the project
11996 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11997 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11998 changed project type to Generic Project so that can be correcly converted to VS.NET project
12000 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12002 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12004 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12006 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12007 added return 0 statements after assert() to make compiler happy
12009 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12010 added newline in the def file to keep MSC compiler satisfied
12012 * sdcc/src/z80/gen.c:
12013 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12014 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12015 - solved MSC error in function aopDump()
12017 * sdcc_vc.h: define PREFIX as "\\sdcc"
12019 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12195 Previous fix was not good. basic blocks that have "break" or "return" are
12196 not really partof a loop , but live ranges used in these blocks should
