1964 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1966 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1967 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1969 One basic decision: e.g. src/clean.mk includes further files. In order
1970 to make this work there are two solutions:
1971 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1972 run configure on them. This way they can use
1973 'include $(srcdir)/port-clean.mk'
1974 - always include clean.mk by the Makefile at the same level. To avoid
1975 that `make clean` tries to include and build Makefile.dep the
1976 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1977 implemented, because now even `make uninstall` doesn't create
1978 Makefile.in. clean.mk could be eliminated by pasting it in
1981 * debugger/mcs51/Makefile.in: build own objects from library sources
1982 (SLIB, SDCC) in current directory
1984 * configure, configure.in: renamed --disable-device-lib-build in
1985 --disable-device-lib; added --enable-doc, the required tools are
1986 searched by configure; added result message; the toolchain for the
1987 belonging ports are now only built, if the port is enabled.
1989 * support/regression/*: all output is written in directory gen, because
1990 the fwk and ports directories don't livet in the build tree using vpath
1992 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1993 --disable-device-lib, added --enable-doc, added section VPATH
1995 * sim/ucsim/configure.in,
1996 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1997 z80 are enabled by default
1999 2006-04-24 Raphael Neider <rneider AT web.de>
2001 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2002 to config word, "pic14_"-prefixed some extern functions
2003 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2004 config word has been found
2005 * src/pic/device.h: added prototypes
2006 * src/pic/pcode.c: added "pic14_"-prefix where needed

2009 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2247 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2249 * src/mcs51/gen.c (genCall): fixed bug 1457608
2251 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2253 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

2256 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2258 * src/SDCCpeeph.c (operandsLiteral): new, added,

2269 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2270 implemented patch 1120823 Thanks to Willy De la Court (normal
2271 interrupts need an interrupt number now if they are made critical),
2272 and enabled nesting of critical functions though not for gbz80
2273 (genCritical, genEndCritical): added functions
2274 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2275 * src/z80/mappings.i: added "ei" to all mappings
2277 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2279 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2280 submitted by the Debian SDCC maintainer Aurelien Jarno:
2281 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2282 archive with gcc 4.1 on mips and wrote the patch"
2284 2006-03-16 Raphael Neider <rneider AT web.de>
2286 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2287 the left operand is shorter than the result (c* = lit-c* + int),
2289 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2292 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2294 * src/.version: increased version number to 2.5.5
2295 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2296 linking is done manually in pic16 port's _linkEdit,
2297 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2298 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2299 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2300 allocate asmop as AOP_ACC,
2301 (aopForRemat): added parameter 'bool result' in function declaration,
2302 (pic16_aopGet): return AOP_ACC when accessing WREG,
2303 (pic16_popGetTempReg): minor modification,
2304 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2305 'pic16_allocWithIdx',
2306 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2307 calling function in absolute addresses,
2308 (genAssign): take into account AOP_ACC asmop,
2309 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2310 * src/pic16/pcoderegs.c: some debug functions and lines added,

2312 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2314 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2315 call to allocReg, not by manually allocating a new one,
2316 (pic16_assignRegisters): now before going through the register
2317 allocating functions mark all registers as free. This eliminates some
2318 side effects resulting from peephole parser done earlier in the backbone
2320 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2322 * src/SDCCicode.c (geniCodeLogic),

2341 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2342 (aopForSym, aopOp): increment asmop.allocated if reused,
2343 (freeAsmop): decrement asmop.allocated and check for zero instead of
2345 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2346 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2347 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2370 2006-03-06 Borut Razem <borut.razem AT siol.net>
2372 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2373 made the linker quiet
2375 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2377 * src/pic16/gen.c (genPcall): fixed bug #1443644
2378 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2379 which dumps before the function entry point a data byte which represents
2380 the number of the local variables used by the specified function, added
2381 'xinst' for initial support for Extended Instruction Support,
2382 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2383 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2384 port->fun_prefix anymore (may change later),
2385 (genFunction, genEndFunction): do not store/restore local registers for
2386 _main (this should take care the --main-return command line option in
2388 (genOr): removed some legacy pic-port instructions,
2389 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2390 performing operations with SFR's causes data to be written more than
2391 once to each SFR. Perhaps SFRs should be handled in special cases...
2392 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2394 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2395 into account for stack starting position,
2396 (struct OPTIONS pic16_optionsTable): added command line argument
2397 --extended or -y for Extended Instruction Support,
2398 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2399 (deassignLRs): *** perhaps the most important change, old 'for' code
2400 (commented out for reference), didn't account for some registers which
2401 were left marked 'not free' after a pointer operation. The change
2402 reduces register usage a lot in some cases
2404 2006-03-04 Borut Razem <borut.razem AT siol.net>
2406 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4727 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4728 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4729 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4730 immedDom() returning wrong block; probably fixes bug #1160833)
4732 2005-03-20 Borut Razem <borut.razem AT siol.net>
4734 * support/scripts/inc2h.pl: WIN32 port
4736 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4738 * device/lib/makefile.in: added abs.c and labs.c
4740 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4742 * device/include/stdint.h: added
4743 * device/lib/abs.c: added
4744 * device/lib/labs.c: added
4745 * device/include/stdlib.h: added abs() and labs() prototypes
4746 * device/lib/libsdcc.lib: added abs and labs
4747 * device/include/float.h,
4748 * device/lib/_fsmul.c,
4749 * device/lib/printf_fast.c,
4750 * device/lib/printf_tiny.c: updated comments
4752 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4754 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4757 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4759 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4760 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4762 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4764 * device/lib/printf_large.c: removed inline assembly for portability and
4765 readability. Use printf_fast if speed or size are more important.
4766 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4767 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4769 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4771 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4772 prevent compiler warning
4774 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4776 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4777 moved to level 0 and declared as static. Also they are explicit
4778 placed in access bank. This was necessery because some times they
4779 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4780 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4781 optimizations. Currently only compare to unsigned char is implemented,
4782 * src/pic16/gen.c: added fReturnIdx array,
4783 * (struct resolvedIfx) is moved to gen.h and made public,
4784 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4785 * (aopForSym): added an optimization to directly store in stack of
4786 the operand of a SEND iCode,
4787 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4788 but as registers instead (AOP_REG) using the fReturnIdx array,
4789 * (pic16_freeAsmop): remove the freed register from the
4790 _G.sregsAlloc field,
4791 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4792 a compare of 'WREG',
4793 * (pic16_popGetTempRegCond): changed function prototype, now
4794 function takes also a bitVector argument v which holds the current
4795 set of registers that are allocated for stack access by aopForSym,
4796 registers allocated in aopForSym for accessing stack symbols are not
4797 any more part of the functions usedRegs field,
4798 * (genCall): some times aopOp is called for a stack variable to be
4799 send, aopForSym might perform the push, if this is true make sure
4800 that genCall doesn't push the variable twice by testing _G.resDirect,
4801 * (genFunction): changed testing for unspecified interrupt number
4802 from 256 to INTNO_UNSPEC,
4803 * modified selection scheme of frame pointer generation. Previously
4804 if function did use local registers a frame pointer was generated,
4805 now a frame pointer is generated only if function has arguments
4806 (that need PLUSW2 register access), or has stack arguments, or the
4807 compiler is not instructed to omit the frame pointer,
4808 * (genEndFunction): before restoring local registers that were saved
4809 in the function preamble, also restore the registers that *might*
4810 have been allocated for stack access,
4811 * (genRet): removed some old comments,
4812 * (genCmp, the active (RN's) version): added a call to the
4813 pic16_genCmp_special function to perform the compare with a more
4814 robust and optimized way,
4815 * (genInline): a feature has been added in inline code generation,
4816 which allows a wildcard variable substitution when writing inline
4817 assembly. Code is incomplete and experimental therefore undocumented,
4818 * (genCast): changed order of aopOp for result and right to allow
4819 aopForSym to directly load the result if possible,
4820 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4821 perform an optimized compare on some selected special occasions,
4822 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4823 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4824 generate an IVT any more,
4825 * src/pic16/main.c (pic16_optionsTable): added command line option
4827 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4828 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4830 * src/pic16/NOTES: Raphael Neider added in list of active developers
4831 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4832 jumptable_end to prevent bug #,
4833 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4834 inCond and outCond fields,
4835 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4836 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4837 turn off register spilling,
4838 * (packRegsForOneUse): synced with other ports' versions although it
4839 is not used currently,
4840 * (pic16_packRegisters): added an optimization while reading
4841 structure bitfields, some registers may be saved (malloc code is
4842 decreased by 80 bytes)
4844 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4846 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4847 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4848 this can be optimized more?
4850 2005-03-10 Raphael Neider <rneider AT web.de>
4852 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4853 genNearPointerGet): (hopefully) fixed access to bitfields via
4854 pointers (p->bitN = x; and x = p->bitN; failed)
4856 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4899 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4900 to keep the correct label reference count when adding/removing references
4901 to labels. A peephole file using this is appended to patch #1144962.

5043 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5044 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5045 this might fix SIGSEGVs on MinGW...
5046 * src/SDCCopt.c (killDeadCode): restored original behaviour
5047 (volatile operands might get thrown away though)
5049 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5133 * (genUminus): rewritten to for efficiency
5134 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5135 used uninitialized in some cases)
5136 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
5137 copy the third byte from the int -- now assumes 0x80 (data memory)
5138 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5139 operands (genAddLit expects the iCode's operands to swapped as
5140 well), fixed leftover bytes (crashed for short left operands)

5490 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5491 Now 4 algorithms for mcs51 jumptable generation are used:
5492 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5524 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5526 * added libc directory. The current version of LibC contains string
5527 functions, ctype functions and macros and some functions of the
5528 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5529 be extensively tested in the future. Standard disclaimer here.
5530 Library is not automatically build yet. But one can build it by

5542 * (pic16_storeForReturn): optimized return of 0,
5543 * (genCmp): experimental code for new genCmp which uses PIC18's
5544 special compare&skip instructions. Initial tests fail some times
5545 with variables grater than 1 byte in size, so new code is disabled,
5546 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5548 * (genCast): began a fix to optimize the casting of a bit to another
5549 bit, now assigning a bitfield to another bitfield will fail, sorry,

5558 and 1 for banking instruction,
5559 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5560 caused stop processing pCodes after a inline assembly block,
5561 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5563 registers when it shouldn't,
5564 * src/pic16/ralloc.c (allocReg): add preliminary support for
5565 supporting a limited set of temporary registers,
5567 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5569 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5572 (loadRegFromAop): recognize CLRH optimization,
5573 (genFunction): optimize RECEIVE iCodes in reentrant functions
5575 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8572 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8574 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8575 loaded with the linker search paths (-L arguments) and the libraries
8576 to be linked with the current source (-l arguments). Changes
8577 currently will affect only the pic16 port.
8578 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8579 include path the port specific paths and port specific libraries,
8580 * gplink command now contains the $3 argument,
8581 * src/pic16/device.h,
8582 * src/pic16/device.c,: structure PIC_device is made public and
8583 renamed to PIC16_device, the same for variable Pics which is renamed

8598 Documenting changes from previous commits.
8599 * configure.in (version 1.56),
8600 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8601 when generating output files to configure the pic16 library,
8602 but now I've commented it out, since gputils aren't installed in the
8603 SF compile farm, so library won't compile
8605 * device/lib/Makefile.in (version 1.56): initially I've added in
8606 target 'all' the prerequestive 'model-pic16' so it compiled the
8607 pic16 library, but now I've commented it out for the same reasons
8609 * added targets 'model-pic16' and 'objects-pic16' to compile the
8611 * added target 'port-specific-objects-pic16' to handle the
8612 generated libraries and copy them into the build/ directory
8613 * added target 'clean-intermediate-pic16' to clean intermediate
8614 files into pic16 directory
8615 * in target 'installdirs' added line to create directory pic16 in
8616 the installation path
8618 * device/include/Makefile.in (version 1.11): in target 'install'
8619 added lines to copy all header files to installation path,
8620 * in target 'installdirs' added line create directory for pic16
8621 headers in the installation path

8636 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8637 option so that it actually works. Made it specific to the z80, since
8638 the gbz80 doesn't have these kinds of I/O ports.
8640 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8642 * device/include/z180.h,

8666 via literal number. The symbol is placed in the corresponding
8667 position of the data ram
8668 * (pic16_dump_section): relocatable and absolute uninitialized
8669 data are now emitted in sorted order to reduce section naming,
8670 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8671 weren't marked as being in the access bank,
8673 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8675 Added portion of GNU PIC Library under the directory
8676 device/include/pic16 and device/lib/pic16. These files
8677 contain the declarations of SFRs for the PIC18Fxx2 devices.
8678 The directory is initialized via configure from toplevel.
8680 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8705 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8707 * doc/sdccman.lyx: Moved and added some sections, small changes
8708 all over. Telling LaTeX to be less strict with word spacing
8709 to better keep the right margin. Changed some notes about
8710 maintainance of the ports in section 3.2.1 - is it OK like this?
8712 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8714 SDCC source changes:
8715 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8750 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8752 * src/pic16/peeph.def: all peepholes with movff are commented out,
8753 because there is a problem in the pcode peep optimizer,
8754 * src/pic16/ralloc.c: the register allocator can now reuse local

8864 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8866 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8867 (default behaviour).
8869 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8871 A python script to validate compiler diagnostic messages. It can be
8872 used to verify that sdcc complains about bad c source code and
8873 gives a good location of the error.
8874 * support/valdiag/Makefile,
8875 * support/valdiag/valdiag.py,
8876 * support/valdiag/tests/*

8891 * src/common.h: added ifndef/define/endif macros
8892 around the header file.
8893 Bug reported from Jesus Calvino-Fraga
8895 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8897 * sdcc.spec: updated
8898 * device/include/Makefile.in: don't install CVS directories
8899 * device/lib/Makefile.in: added removal of CVS directories after install
8900 * doc/Makefile: fixed install, added local_icons
8901 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8902 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8903 * src/ds390/gen.c (genRightShift): fixed bug #870788
8904 * src/SDCCast.c (decorateType): fixed bug #870781
8906 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8908 PIC16 port related changes:
8909 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8910 added variable stackPos,
8912 * gen.c: genCall, assignResultValue: added support for
8913 pushing/retrieving function parameters to/from stack,
8914 genFunction,genEndFunction: setup stack frame for the
8916 genAddrOf: will be changed according to bug 863624
8918 * added files genutils.c and genutils.h which contain gen*
8919 debugged and optimised functions extracted from gen.c
8921 * glue.c: added variable 'externs' which holds extern symbols,
8922 pic16emitRegularMap: is modified to properly handle relocatable
8923 symbols under the new scheme,
8924 pic16createInterruptVect: is modified
8925 pic16printPublics: is modified to emit 'global' assembler directives,
8926 added pic16_printExterns to print extern symbols,
8927 pic16glue: initializes stack/frame pointer in the beginning of
8928 the assembly output. Temporary hack, will be corrected later,
8929 because gplink yet does not support stack and SDCC does not
8930 yet support a type of crt0.o object to create the final binary.
8932 * Removed many lines that contain 8051 legacy code.
8933 * The code is finally placed under a 'code' directive.
8934 * Added port specific options.
8936 * _process_pragma: simplified since now we do not need *special*
8937 include file to define SFR registers. But a separate header
8938 will be needed. This will be developed later.
8939 * _pic16_parseOptions: added, parses port specific options:
8940 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8941 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8942 --preplace-udata-with=
8944 * _pic16_setDefaultOptions: modified to initialize section names,
8945 but hack is temporarly out of order since it needs improvement.
8946 * _pic16_genAssemblerPreamble: configuration words are emitted by
8947 their address instead of their name. This part is incomplete and
8948 supports only the 18Fxx2 devices. Other devices will emit an error
8949 during assembly since they do not contain the same set of config
8951 * _pic16_genIVT: is modified,
8953 * pcode.c: added definitions for some hardware registers that are needed
8955 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8956 All PCI entries are updated. Now LFSR is supported.
8957 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8958 * added pic16_newpCodeOpLit2 to support instructions with
8959 two literal arguments
8960 * pic16_pCode2str: corrected code that emits assembler instructions
8961 with two literal operands and those that have an access bit modifier
8962 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8963 this fixes a bug which caused some labels to be lost, when an
8964 assembler directive was added, i.e. banksel,
8965 * pic16_FixRegisterBanking: improved logic that causes the insertion
8967 * InlineFunction: functions that are called once, are not any more
8968 inlined. This can be a port option in the future,
8970 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8972 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8973 hold the corresponding uninitialized symbols,
8974 * pic16_allocProcessorRegister: registers have explicit marked the
8976 * pic16_allocInternalRegister: registers are explicit marked as
8978 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8979 processing list, so bit registers were lost,
8982 * ralloc.h: added field 'accessBank' and original symbol operand
8983 in register definition,
8984 * removed the field isMapped from register definition,
8986 ** Several functions have been removed from various sources:
8987 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8988 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8989 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8990 pic16_assignRelocatableRegisters
8992 ** others have been introduced:
8993 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8994 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8996 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8998 * support/scripts/inc2h.pl: changed definition of BIT_AT
8999 to emit 'sbit at' instead of 'bit at'. This was a request.
9001 PIC16 port related preliminary changes:
9002 * gen.c: prefixed function popRegFromString with
9003 pic16_ and all references to it corrected
9004 * pcode.c: all pic16_pc_* hardware registers prefixed
9005 with underscore (_),
9006 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9007 * ralloc.c: newReg(): when register is REG_SFR then
9008 set address to rIdx,
9009 pic16_allocProcessorRegister(): marks register wasUsed=0
9010 pic16_writeUsedRegs(): added a call to assign processor
9011 registers via pic16_assignFixedRegisters
9013 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9015 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9016 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9017 variables in unused register banks. Also the SSEG is placed
9018 wherever there is enough space for it, and IDATA can be anywhere
9019 in internal RAM. For now compile using -Wl-Y[stack_size].
9020 The mem file is different for this option as well, since it
9021 makes no sense of talking about DSEG lenght.
9023 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9025 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9026 in certain cases, e.g. when ROM assignment, patch provided
9027 from Albert den Haan.
9029 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9172 * src/mcs51/peephole.def,
9173 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9174 (allows non-interrupt and interrupt code to safely compete for a resource

9935 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9937 Fixed bug #621531 (const & volatile confusion in the type chain).
9938 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

10018 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10019 iCode properly now. Use getSize instead of nRegs since a & b
10020 aren't part of the nRegs tally.
10022 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10024 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10033 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10034 copied from genNearPointerSet()
10035 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10036 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10037 If they pop r0/r1 they must be called in the opposite order than aopOp().
10038 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10039 (resp. --stack-auto), prepared for --xstack

10052 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10053 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10054 type for bits was changed. It resulted in bit variables becoming
10055 global, which is not permitted in PIC 14 assembly output.
10057 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10059 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10072 A few small changes that speed up the peephole optimizer.
10076 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10078 Try to make the peephole optimizer smarter by maintaining
10079 an association between the assembly source code and the
10080 iCodes that originated them. Put this information to use
10081 with a new peephole rule condition "notVolatile" so that
10082 the rules can be aggressive yet still safe.
10087 * src/mcs51/peeph.def
10089 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10093 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10094 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10095 if the left or right operand symbols have the accuse flag set.
10097 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10099 Changed the type of the result of the ! (NOT) operator to char;
10100 previously it returned the same type as the source. This allows
10101 us to eliminate all the genFloatNot functions (all of its target
10102 implementations were very buggy) since !float can use the same
10105 * src/SDCCicode.c (ast2iCode): ! returns char

10107 * src/ds390/gen.c (genNot, genNotFloat),
10108 * src/z80/gen.c (genNot, genNotFloat),

10114 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10115 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10116 during interrupts. Ensure WSAVE is located at a shared bank address.
10117 2. Fixed page selection in some places
10118 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10119 the registers name strings.
10120 4. Fixed "signed / unsigned compare" compiler warnings.
10121 5. The PIC port manages its own allocation of the general purpose
10122 registers, but makes no attempt to reuse them. As a result when
10123 compiling it soon runs out of general purpose registers. Some
10124 additional code was added to the files pcode.c and device.c to walk
10125 through the function call tree and rename the registers so that they
10135 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10136 genPlus() & genMinus() when the result is the same as left or right
10138 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10142 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10144 Made bitfield a distinct type from bit so that bitfields
10145 convert as per ANSI C and bits retain their traditional
10146 boolean style behaviour. Implemented bitfield support in
10154 * src/ds390/gen.c: bit v bitfield split
10155 * src/z80/gen.c: New support for bitfields
10156 * support/regression/tests/bitfields.c: reenabled z80,
10159 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10161 Rules 246.x, 247.x relate to bitfields, the others speed up
10162 access to xdata mapped I/O devices.
10164 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10166 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10168 Cleaned up genPackBits and genUnpackBits and added two helper
10169 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10170 for literal assignments in genPackBits (thanks to Frieder for
10176 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10178 Fixed bug #748310 (pointer to function type mishandled when the
10179 function name is omitted). Also fixed a SIGSEGV when a function
10180 attribute (reentrant, etc) is used on a non-function or on a
10181 function but misplaced before the parameter list.
10183 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10185 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10186 * support/Util/SDCCerr.h,
10187 * support/Util/SDCCerr.c: Added func attr misuse error msg
10189 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10191 Fixed bug #787649 by anonymous
10192 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10193 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10195 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10197 Fixed numerous bitfield problems.
10199 * src/SDCC.y: More bitfield related error checking
10201 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
10202 * support/Util/SDCCerr.h,
10203 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
10204 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs

10208 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10210 Made the constant following the "interrupt" keyword optional. If
10211 omitted, the function will not automatically be given an entry
10212 in the interrupt vector table (similar to #pragma NOIV, but
10213 less syntacticly kludgy). The interrupt number is also now
10214 range checked. Also fixed a bug in the high order bit example
10221 * support/Util/SDCCerr.c
10222 * support/Util/SDCCerr.h

10232 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10233 be re-activated by defining REDUCE_LITERALS)
10234 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10235 unsigned, but are signed by default
10236 * src/SDCCval.c (constVal): rearranged
10237 * src/SDCCval.c (valMod): preliminary fix
10238 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10279 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10280 constants are unsigned; added recognition of "u" flag for unsigned
10281 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10282 * src/SDCCval.c (valDiv, valMod): fixed signdness
10283 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10284 signedness of modulo, left and right shift

10730 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
10732 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
10734 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10735 it can be defined with CFLAGS when running configure
10736 * src/SDCCmain.c: fixed compiling + linking with object files
10738 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10740 * configure.in: configure for pic16 port,
10741 added --disable-pic16-port
10742 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10743 * src/SDCCmain.c: linkOptions is changed to set *,
10744 added if/endif conditional macros to remove options help
10745 messages from optionsTable when a port is not configured, added
10746 support for the PIc16 port in the ports table, when executing
10747 the compiler with no port specified on command line, a default
10748 port is selected with the new macro DEFAULT_PORT which is
10749 defined in port.h, in setDefaultOptions() linkOptions is removed
10750 from initialization assignment, since now it is a set,
10751 parseCmdLine uses setParseWithComma for linkOptions, in
10752 linkEdit() linkOptions are accessed with new function indexSet()
10753 which returns the i'th item of a set variable. See SDCCset.c, in
10754 linkEdit() when calling buildCmdLine(), added linkOptions as
10755 last argument. Now users can pass arguments to gplink via the
10756 -Wl option, main() uses pic16glue() to glue up pic16 programs
10757 * src/SDCCpeeph.c: various changes to support pic16
10758 * src/SDCCset.c: added function void *indexSet(set *, int) to
10759 return the i'th item of the set

10764 added macro DEFAULT_PORT
10765 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
10766 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
10768 * src/pic16/glue.c: commented out some error producing lines
10769 * src/pic16/main.c: __config directives are commented out to stop
10770 gpasm complaining and test the linkage with gplink, _linkCmd and
10771 _asmCmd changed to be more gplink and gpasm friendly
10772 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10773 produced an error when parsed, peep rule 12 is added to utilize
10774 movff, but it is commented out since the pCode does not support
10775 yet a command with 2 address arguments
10777 2003-05-18 <johan AT balder>
10779 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11827 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11828 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11834 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11835 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11837 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11838 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11840 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11842 * in /sdcc/as/mcs51/ changed these files in order to create an
11843 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11844 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11845 following files to include the previous two files: aslink.dsp,
11846 Makefile.aslink, Makefile.bcc, and Makefile.in.
11848 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11849 .adb instead of .cdb
11851 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11853 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11854 value from option --iram-size.
11856 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11858 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11861 2002-09-18 <wiml AT hhhh.org>
11863 * SDCClrange.h: exposed setFromRange() and setToRange()
11864 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11865 packRegsForAccUse() (bug 542397)
11866 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11867 multiple times and emitting the fetch operations more than once
11868 added aopGetUsesAcc() function to allow binary operators to
11869 fetch their operands in the correct order; made genMinus() emit
11870 compact code for X = LITERAL - Y
11872 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11873 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11874 sprintf() in line 1267.
11876 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11877 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11880 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11881 Changes to aslink (All the changes are marked with 'JCF'):
11883 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11886 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11887 area BSEG. Also moves, if possible, the DATA area down into the internal
11888 ram so more space is available.
11890 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11893 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11894 not bytes. Function summary() which creates a memory usage summary
11895 file with extension .mem. Reports of overlaping stack and small stack
11896 size. If the space for the stack is less than 16 bytes aslink trows a
11899 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11900 the 8051. Option 'y' for memory summary output file.
11902 Changes to sdcc (All the changes are marked with 'JCF'):
11904 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11906 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11907 overlaying area for it (uses RegBankUsed[4]).
11909 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11910 bank zero as used by default. By default aslink locates the stack
11911 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11912 the creation of the .mem file. Delegates the allocation of data area
11913 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11914 the begining of the stack area to aslink.
11916 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11917 glue() in SDCCglue.c creates an area for it.
11919 2002-09-03 Borut Razem <borut.razem AT siol.net>
11920 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11921 sdcc/src/pic/glue.c:
11922 introduced atexit() handler for teporay files removal in case of
11923 errors, assertions, ...
11925 2002-08-29 Borut Razem <borut.razem AT siol.net>
11926 * sdcc/support/cpp2/auto-host_vc_in.h:
11927 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11928 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11929 Maybe there is a similar problem with BORLANDC? It should be checked!
11931 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11932 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11933 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11934 was not executed, and the compiler (cl) launched a warning:
11935 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11937 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11938 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11940 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11941 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11943 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11944 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11945 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11946 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11947 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11948 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11949 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11950 - added Release configuration in VS projects
11951 - review of compiler an linker options
11952 - VC .exe files are generated in bin_vc directory, not to interfere
11953 with binaries generated from other projects (cygwin, mingw, bcc ...)
11955 * sdcc/src/yacc.dsp: added
11957 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11958 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11959 and insert the version number definitions from .version
11961 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11963 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11964 added - genarate auto-host.h using auto-host_vc_in.h as template
11967 removed from CVS, generated automatically
11969 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11970 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11972 2002-08-11 Borut Razem <borut.razem AT siol.net>
11973 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11975 2002-08-10 Borut Razem <borut.razem AT siol.net>
11976 * src/SDCCmain.c (main):
11977 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11978 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11979 The consequence was that some temporary files were not removed.
11982 unification of code in functions tempfilename() and tempfile():

12191 Previous fix was not good. basic blocks that have "break" or "return" are
12192 not really partof a loop , but live ranges used in these blocks should
