2043 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2045 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2046 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2048 One basic decision: e.g. src/clean.mk includes further files. In order
2049 to make this work there are two solutions:
2050 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2051 run configure on them. This way they can use
2052 'include $(srcdir)/port-clean.mk'
2053 - always include clean.mk by the Makefile at the same level. To avoid
2054 that `make clean` tries to include and build Makefile.dep the
2055 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2056 implemented, because now even `make uninstall` doesn't create
2057 Makefile.in. clean.mk could be eliminated by pasting it in
2060 * debugger/mcs51/Makefile.in: build own objects from library sources
2061 (SLIB, SDCC) in current directory
2063 * configure, configure.in: renamed --disable-device-lib-build in
2064 --disable-device-lib; added --enable-doc, the required tools are
2065 searched by configure; added result message; the toolchain for the
2066 belonging ports are now only built, if the port is enabled.
2068 * support/regression/*: all output is written in directory gen, because
2069 the fwk and ports directories don't livet in the build tree using vpath
2071 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2072 --disable-device-lib, added --enable-doc, added section VPATH
2074 * sim/ucsim/configure.in,
2075 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2076 z80 are enabled by default
2078 2006-04-24 Raphael Neider <rneider AT web.de>
2080 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2081 to config word, "pic14_"-prefixed some extern functions
2082 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2083 config word has been found
2084 * src/pic/device.h: added prototypes
2085 * src/pic/pcode.c: added "pic14_"-prefix where needed

2088 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2091 (pic14createInterruptVect): moved generating __config directives away

2107 * device/examples/main8051.c: deleted - it was removed from CVS

2111 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2349 implemented patch 1120823 Thanks to Willy De la Court (normal
2350 interrupts need an interrupt number now if they are made critical),
2351 and enabled nesting of critical functions though not for gbz80
2352 (genCritical, genEndCritical): added functions
2353 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2354 * src/z80/mappings.i: added "ei" to all mappings

2366 the left operand is shorter than the result (c* = lit-c* + int),
2368 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2371 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2373 * src/.version: increased version number to 2.5.5
2374 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2375 linking is done manually in pic16 port's _linkEdit,
2376 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2377 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2378 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2379 allocate asmop as AOP_ACC,
2380 (aopForRemat): added parameter 'bool result' in function declaration,
2381 (pic16_aopGet): return AOP_ACC when accessing WREG,
2382 (pic16_popGetTempReg): minor modification,

2393 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2394 call to allocReg, not by manually allocating a new one,
2395 (pic16_assignRegisters): now before going through the register
2396 allocating functions mark all registers as free. This eliminates some
2397 side effects resulting from peephole parser done earlier in the backbone
2399 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2457 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2458 which dumps before the function entry point a data byte which represents
2459 the number of the local variables used by the specified function, added
2460 'xinst' for initial support for Extended Instruction Support,
2461 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2462 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2463 port->fun_prefix anymore (may change later),
2464 (genFunction, genEndFunction): do not store/restore local registers for
2465 _main (this should take care the --main-return command line option in
2467 (genOr): removed some legacy pic-port instructions,
2468 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2469 performing operations with SFR's causes data to be written more than
2470 once to each SFR. Perhaps SFRs should be handled in special cases...
2471 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2473 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2474 into account for stack starting position,
2475 (struct OPTIONS pic16_optionsTable): added command line argument
2476 --extended or -y for Extended Instruction Support,
2477 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2478 (deassignLRs): *** perhaps the most important change, old 'for' code
2479 (commented out for reference), didn't account for some registers which
2480 were left marked 'not free' after a pointer operation. The change
2481 reduces register usage a lot in some cases
2483 2006-03-04 Borut Razem <borut.razem AT siol.net>

4748 on rIfx (genCmp was broken)
4750 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4752 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4753 * src/z80/main.c (_keywords[]),
4754 * src/SDCCglobal.h (struct options),
4756 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4757 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4758 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4759 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4760 always available in leading double underscore form. The C99 support is
4761 mostly missing, but it's a start.
4762 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4763 reserved identifier "__data".
4765 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4811 2005-03-20 Borut Razem <borut.razem AT siol.net>
4813 * support/scripts/inc2h.pl: WIN32 port

4841 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4843 * device/lib/printf_large.c: removed inline assembly for portability and
4844 readability. Use printf_fast if speed or size are more important.
4845 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4846 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4848 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4850 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4851 prevent compiler warning
4853 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4855 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4856 moved to level 0 and declared as static. Also they are explicit
4857 placed in access bank. This was necessery because some times they
4858 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4859 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4860 optimizations. Currently only compare to unsigned char is implemented,
4861 * src/pic16/gen.c: added fReturnIdx array,
4862 * (struct resolvedIfx) is moved to gen.h and made public,
4863 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4864 * (aopForSym): added an optimization to directly store in stack of
4865 the operand of a SEND iCode,
4866 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4867 but as registers instead (AOP_REG) using the fReturnIdx array,
4868 * (pic16_freeAsmop): remove the freed register from the
4869 _G.sregsAlloc field,
4870 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4871 a compare of 'WREG',
4872 * (pic16_popGetTempRegCond): changed function prototype, now
4873 function takes also a bitVector argument v which holds the current
4874 set of registers that are allocated for stack access by aopForSym,
4875 registers allocated in aopForSym for accessing stack symbols are not
4876 any more part of the functions usedRegs field,
4877 * (genCall): some times aopOp is called for a stack variable to be
4878 send, aopForSym might perform the push, if this is true make sure
4879 that genCall doesn't push the variable twice by testing _G.resDirect,
4880 * (genFunction): changed testing for unspecified interrupt number
4881 from 256 to INTNO_UNSPEC,
4882 * modified selection scheme of frame pointer generation. Previously
4883 if function did use local registers a frame pointer was generated,
4884 now a frame pointer is generated only if function has arguments
4885 (that need PLUSW2 register access), or has stack arguments, or the
4886 compiler is not instructed to omit the frame pointer,
4887 * (genEndFunction): before restoring local registers that were saved
4888 in the function preamble, also restore the registers that *might*
4889 have been allocated for stack access,
4890 * (genRet): removed some old comments,
4891 * (genCmp, the active (RN's) version): added a call to the
4892 pic16_genCmp_special function to perform the compare with a more
4893 robust and optimized way,
4894 * (genInline): a feature has been added in inline code generation,
4895 which allows a wildcard variable substitution when writing inline
4896 assembly. Code is incomplete and experimental therefore undocumented,
4897 * (genCast): changed order of aopOp for result and right to allow
4898 aopForSym to directly load the result if possible,
4899 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4900 perform an optimized compare on some selected special occasions,
4901 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4902 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4903 generate an IVT any more,
4904 * src/pic16/main.c (pic16_optionsTable): added command line option
4906 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4907 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4909 * src/pic16/NOTES: Raphael Neider added in list of active developers
4910 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4911 jumptable_end to prevent bug #,
4912 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4913 inCond and outCond fields,
4914 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4915 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4916 turn off register spilling,
4917 * (packRegsForOneUse): synced with other ports' versions although it
4918 is not used currently,
4919 * (pic16_packRegisters): added an optimization while reading
4920 structure bitfields, some registers may be saved (malloc code is
4921 decreased by 80 bytes)
4923 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4925 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4926 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4927 this can be optimized more?
4929 2005-03-10 Raphael Neider <rneider AT web.de>
4931 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4932 genNearPointerGet): (hopefully) fixed access to bitfields via
4933 pointers (p->bitN = x; and x = p->bitN; failed)
4935 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5112 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5113 (sizeof(sectNames) changed to sizeof(sectName))
5114 Both patches fix segfaults under MinGW.
5116 2005-01-23 Raphael Neider <rneider AT web.de>

5119 Safe_[mc]?alloc()'ed variables
5120 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5121 of (byte sized) temporaries (assign them to WREG for now)
5122 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5123 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5124 this might fix SIGSEGVs on MinGW...
5125 * src/SDCCopt.c (killDeadCode): restored original behaviour
5126 (volatile operands might get thrown away though)
5128 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5130 * src/pic16/gen.c: fixed bug #1106975,

5135 * added function attribute 'shadowregs' to take advantage of shadow
5137 * added function attribute 'wparam' as an alternative to the wparam
5139 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
5140 user declares a non-ISR function as 'shadowregs',
5141 * doc/sdccman.lyx: updated to reflect recent changes of pic16 port

5592 * src/pic16/genarith.c,
5595 * src/pic16/pcode.c: applied patches #1068154 and #1070213
5597 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
5599 Large cummulative patch for pic16 port.
5600 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5601 to call when a stack overflow occurs,
5602 * (malloc.h): added CVS Id tag,
5603 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5605 * added libc directory. The current version of LibC contains string
5606 functions, ctype functions and macros and some functions of the
5607 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5608 be extensively tested in the future. Standard disclaimer here.
5609 Library is not automatically build yet. But one can build it by
5610 invoking 'make' inside the libc directory.
5611 * added ADC library under libio. Preliminary version yet.
5613 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5614 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5615 aopForRemat() now and not by pic16_aopOp(),
5616 * (pic16_popGetTempReg): removed warning messgae when allocating
5617 temporary registers, its a buggy feature and will be removed,
5618 * (pic16_popGet): set register instance field in AOP_CRY,
5619 * (pic16_outBitC): fixed for results in size greater than 1,
5620 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5621 * (pic16_storeForReturn): optimized return of 0,
5622 * (genCmp): experimental code for new genCmp which uses PIC18's
5623 special compare&skip instructions. Initial tests fail some times
5624 with variables grater than 1 byte in size, so new code is disabled,
5625 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5627 * (genCast): began a fix to optimize the casting of a bit to another
5628 bit, now assigning a bitfield to another bitfield will fail, sorry,
5629 * src/pic16/main.c: disabled the use of lr-support feature,
5630 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5631 * added some function prototypes, added function _debugf prototype,
5632 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5633 bits with offset (case PO_GPR_BIT),
5634 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5636 * (isBankInstruction): modified to return 0 for no banking instruction,
5637 and 1 for banking instruction,
5638 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5639 caused stop processing pCodes after a inline assembly block,
5640 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5641 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5642 registers when it shouldn't,
5643 * src/pic16/ralloc.c (allocReg): add preliminary support for
5644 supporting a limited set of temporary registers,
5646 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5648 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5649 genDataPointerSet): ensure assignments always copy in MSB to LSB
5651 (loadRegFromAop): recognize CLRH optimization,
5652 (genFunction): optimize RECEIVE iCodes in reentrant functions
5654 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5656 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5657 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5659 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5665 * device/lib/_gptrget.c (_gptrget),
5666 * device/lib/_gptrgetc.c (_gptrgetc),
5667 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5668 instead of sjmp to ret
5669 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5670 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5672 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8654 loaded with the linker search paths (-L arguments) and the libraries
8655 to be linked with the current source (-l arguments). Changes
8656 currently will affect only the pic16 port.
8657 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8658 include path the port specific paths and port specific libraries,
8659 * gplink command now contains the $3 argument,

8679 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8680 when generating output files to configure the pic16 library,
8681 but now I've commented it out, since gputils aren't installed in the
8682 SF compile farm, so library won't compile
8684 * device/lib/Makefile.in (version 1.56): initially I've added in
8685 target 'all' the prerequestive 'model-pic16' so it compiled the
8686 pic16 library, but now I've commented it out for the same reasons
8688 * added targets 'model-pic16' and 'objects-pic16' to compile the
8690 * added target 'port-specific-objects-pic16' to handle the
8691 generated libraries and copy them into the build/ directory
8692 * added target 'clean-intermediate-pic16' to clean intermediate
8693 files into pic16 directory
8694 * in target 'installdirs' added line to create directory pic16 in
8695 the installation path
8697 * device/include/Makefile.in (version 1.11): in target 'install'
8698 added lines to copy all header files to installation path,
8699 * in target 'installdirs' added line create directory for pic16
8700 headers in the installation path

8715 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8716 option so that it actually works. Made it specific to the z80, since
8717 the gbz80 doesn't have these kinds of I/O ports.
8719 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8721 * device/include/z180.h,

8730 portmode; added deprecation warning for bank= and protmode= forms.
8731 Also, guard against buffer overflow.
8732 * src/z80/gen.c (aopGet): generate better code for sfr banked read
8734 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8736 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

8739 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
8741 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8743 Mainly changes to support compilation of the device libraries
8744 * src/pic16/device.c: stack is allocated via symbol and not
8745 via literal number. The symbol is placed in the corresponding
8746 position of the data ram
8747 * (pic16_dump_section): relocatable and absolute uninitialized
8748 data are now emitted in sorted order to reduce section naming,
8749 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8750 weren't marked as being in the access bank,
8752 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8754 Added portion of GNU PIC Library under the directory
8755 device/include/pic16 and device/lib/pic16. These files
8756 contain the declarations of SFRs for the PIC18Fxx2 devices.
8757 The directory is initialized via configure from toplevel.
8759 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8761 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8762 the spilllocations to be compared correctly

8786 * doc/sdccman.lyx: Moved and added some sections, small changes
8787 all over. Telling LaTeX to be less strict with word spacing
8788 to better keep the right margin. Changed some notes about
8789 maintainance of the ports in section 3.2.1 - is it OK like this?
8791 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8828 UPPER for immediate operands,
8829 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8831 * src/pic16/peeph.def: all peepholes with movff are commented out,
8832 because there is a problem in the pcode peep optimizer,
8833 * src/pic16/ralloc.c: the register allocator can now reuse local

8835 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8837 Added file src/pic16/NOTES with information about program writing on
8838 the current port version.

8897 * (pic14emitOverlay): modified to emit a commented overlay segment
8898 directive when no overlay data exist
8899 * (picglue): modified to emit uninitialized data segment
8900 according to udata_section_name

8926 include information about variables allocated to the overlay
8929 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8931 * as/mcs51/lkmain.c: Help about -Y option

8943 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8945 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8946 (default behaviour).
8948 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8950 A python script to validate compiler diagnostic messages. It can be
8951 used to verify that sdcc complains about bad c source code and
8952 gives a good location of the error.
8953 * support/valdiag/Makefile,
8954 * support/valdiag/valdiag.py,
8955 * support/valdiag/tests/*
8957 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8972 Bug reported from Jesus Calvino-Fraga
8974 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8976 * sdcc.spec: updated
8977 * device/include/Makefile.in: don't install CVS directories
8978 * device/lib/Makefile.in: added removal of CVS directories after install
8979 * doc/Makefile: fixed install, added local_icons
8980 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8981 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8982 * src/ds390/gen.c (genRightShift): fixed bug #870788
8983 * src/SDCCast.c (decorateType): fixed bug #870781
8985 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8987 PIC16 port related changes:
8988 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8989 added variable stackPos,
8991 * gen.c: genCall, assignResultValue: added support for
8992 pushing/retrieving function parameters to/from stack,
8993 genFunction,genEndFunction: setup stack frame for the
8995 genAddrOf: will be changed according to bug 863624
8997 * added files genutils.c and genutils.h which contain gen*
8998 debugged and optimised functions extracted from gen.c
9000 * glue.c: added variable 'externs' which holds extern symbols,
9001 pic16emitRegularMap: is modified to properly handle relocatable
9002 symbols under the new scheme,
9003 pic16createInterruptVect: is modified
9004 pic16printPublics: is modified to emit 'global' assembler directives,
9005 added pic16_printExterns to print extern symbols,
9006 pic16glue: initializes stack/frame pointer in the beginning of
9007 the assembly output. Temporary hack, will be corrected later,
9008 because gplink yet does not support stack and SDCC does not
9009 yet support a type of crt0.o object to create the final binary.
9011 * Removed many lines that contain 8051 legacy code.
9012 * The code is finally placed under a 'code' directive.
9013 * Added port specific options.
9015 * _process_pragma: simplified since now we do not need *special*
9016 include file to define SFR registers. But a separate header
9017 will be needed. This will be developed later.
9018 * _pic16_parseOptions: added, parses port specific options:
9019 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9020 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9021 --preplace-udata-with=
9023 * _pic16_setDefaultOptions: modified to initialize section names,
9024 but hack is temporarly out of order since it needs improvement.
9025 * _pic16_genAssemblerPreamble: configuration words are emitted by
9026 their address instead of their name. This part is incomplete and
9027 supports only the 18Fxx2 devices. Other devices will emit an error
9028 during assembly since they do not contain the same set of config
9030 * _pic16_genIVT: is modified,
9032 * pcode.c: added definitions for some hardware registers that are needed
9034 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9035 All PCI entries are updated. Now LFSR is supported.
9036 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9037 * added pic16_newpCodeOpLit2 to support instructions with
9038 two literal arguments
9039 * pic16_pCode2str: corrected code that emits assembler instructions
9040 with two literal operands and those that have an access bit modifier
9041 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9042 this fixes a bug which caused some labels to be lost, when an
9043 assembler directive was added, i.e. banksel,
9044 * pic16_FixRegisterBanking: improved logic that causes the insertion
9046 * InlineFunction: functions that are called once, are not any more
9047 inlined. This can be a port option in the future,
9049 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9051 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9052 hold the corresponding uninitialized symbols,
9053 * pic16_allocProcessorRegister: registers have explicit marked the
9055 * pic16_allocInternalRegister: registers are explicit marked as
9057 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9058 processing list, so bit registers were lost,
9061 * ralloc.h: added field 'accessBank' and original symbol operand
9062 in register definition,
9063 * removed the field isMapped from register definition,
9065 ** Several functions have been removed from various sources:
9066 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9067 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9068 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9069 pic16_assignRelocatableRegisters
9071 ** others have been introduced:
9072 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9073 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9075 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9077 * support/scripts/inc2h.pl: changed definition of BIT_AT
9078 to emit 'sbit at' instead of 'bit at'. This was a request.
9080 PIC16 port related preliminary changes:
9081 * gen.c: prefixed function popRegFromString with
9082 pic16_ and all references to it corrected
9083 * pcode.c: all pic16_pc_* hardware registers prefixed
9084 with underscore (_),
9085 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9086 * ralloc.c: newReg(): when register is REG_SFR then
9087 set address to rIdx,
9088 pic16_allocProcessorRegister(): marks register wasUsed=0
9089 pic16_writeUsedRegs(): added a call to assign processor
9090 registers via pic16_assignFixedRegisters
9092 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9094 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9095 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9096 variables in unused register banks. Also the SSEG is placed
9097 wherever there is enough space for it, and IDATA can be anywhere
9098 in internal RAM. For now compile using -Wl-Y[stack_size].
9099 The mem file is different for this option as well, since it
9100 makes no sense of talking about DSEG lenght.
9102 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9104 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9105 in certain cases, e.g. when ROM assignment, patch provided
9106 from Albert den Haan.
9108 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9655 Fixed a number of problems revealed by bug #827883.
9656 * src/SDCCloop.c (loopInvariants): Spill location of the
9657 result operand should be recomputed if extracted from
9658 a loop. Also, don't extract assignments of an iTemp

9661 not occur if the control variable is involved with a
9662 relational operator.

10151 A few small changes that speed up the peephole optimizer.
10155 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10157 Try to make the peephole optimizer smarter by maintaining
10158 an association between the assembly source code and the
10159 iCodes that originated them. Put this information to use
10160 with a new peephole rule condition "notVolatile" so that
10161 the rules can be aggressive yet still safe.
10166 * src/mcs51/peeph.def
10168 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10172 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10173 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10174 if the left or right operand symbols have the accuse flag set.
10176 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10178 Changed the type of the result of the ! (NOT) operator to char;
10179 previously it returned the same type as the source. This allows
10180 us to eliminate all the genFloatNot functions (all of its target
10181 implementations were very buggy) since !float can use the same
10184 * src/SDCCicode.c (ast2iCode): ! returns char
10185 * src/mcs51/gen.c (genNot, genNotFloat),
10186 * src/ds390/gen.c (genNot, genNotFloat),
10187 * src/z80/gen.c (genNot, genNotFloat),

10191 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
10193 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10194 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10195 during interrupts. Ensure WSAVE is located at a shared bank address.
10196 2. Fixed page selection in some places
10197 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10198 the registers name strings.
10199 4. Fixed "signed / unsigned compare" compiler warnings.
10200 5. The PIC port manages its own allocation of the general purpose
10201 registers, but makes no attempt to reuse them. As a result when
10202 compiling it soon runs out of general purpose registers. Some
10203 additional code was added to the files pcode.c and device.c to walk
10204 through the function call tree and rename the registers so that they
10214 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10215 genPlus() & genMinus() when the result is the same as left or right
10217 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10221 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10223 Made bitfield a distinct type from bit so that bitfields
10224 convert as per ANSI C and bits retain their traditional
10225 boolean style behaviour. Implemented bitfield support in
10233 * src/ds390/gen.c: bit v bitfield split
10234 * src/z80/gen.c: New support for bitfields
10235 * support/regression/tests/bitfields.c: reenabled z80,
10238 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10240 Rules 246.x, 247.x relate to bitfields, the others speed up
10241 access to xdata mapped I/O devices.
10243 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10245 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10247 Cleaned up genPackBits and genUnpackBits and added two helper
10248 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10249 for literal assignments in genPackBits (thanks to Frieder for
10255 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10257 Fixed bug #748310 (pointer to function type mishandled when the
10258 function name is omitted). Also fixed a SIGSEGV when a function
10259 attribute (reentrant, etc) is used on a non-function or on a
10260 function but misplaced before the parameter list.
10262 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10264 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

10268 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10270 Fixed bug #787649 by anonymous
10271 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10272 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10274 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10287 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10289 Made the constant following the "interrupt" keyword optional. If
10290 omitted, the function will not automatically be given an entry
10291 in the interrupt vector table (similar to #pragma NOIV, but
10292 less syntacticly kludgy). The interrupt number is also now
10293 range checked. Also fixed a bug in the high order bit example

10312 be re-activated by defining REDUCE_LITERALS)
10313 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10314 unsigned, but are signed by default
10315 * src/SDCCval.c (constVal): rearranged
10316 * src/SDCCval.c (valMod): preliminary fix

10357 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10358 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10359 constants are unsigned; added recognition of "u" flag for unsigned
10360 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10361 * src/SDCCval.c (valDiv, valMod): fixed signdness

10736 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10738 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual

10740 for a non-native english speaker.
10741 Please feel free to add to the manual or to correct my changes.

10769 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10770 the regression tests I'm not brave enough to enable 245.b, 245.c
10771 * doc/sdccman.lyx: added latex preamble for hyperref package.
10772 Using pdflatex this will give you a hyperlinked pdf file with
10773 bookmarks. (prepend '%' before /usepackage if this breaks something)

10822 * src/SDCCmain.c: linkOptions is changed to set *,
10823 added if/endif conditional macros to remove options help
10824 messages from optionsTable when a port is not configured, added
10825 support for the PIc16 port in the ports table, when executing
10826 the compiler with no port specified on command line, a default
10827 port is selected with the new macro DEFAULT_PORT which is
10828 defined in port.h, in setDefaultOptions() linkOptions is removed
10829 from initialization assignment, since now it is a set,
10830 parseCmdLine uses setParseWithComma for linkOptions, in
10831 linkEdit() linkOptions are accessed with new function indexSet()
10832 which returns the i'th item of a set variable. See SDCCset.c, in
10833 linkEdit() when calling buildCmdLine(), added linkOptions as
10834 last argument. Now users can pass arguments to gplink via the
10835 -Wl option, main() uses pic16glue() to glue up pic16 programs
10836 * src/SDCCpeeph.c: various changes to support pic16
10837 * src/SDCCset.c: added function void *indexSet(set *, int) to

10847 * src/pic16/glue.c: commented out some error producing lines
10848 * src/pic16/main.c: __config directives are commented out to stop
10849 gpasm complaining and test the linkage with gplink, _linkCmd and
10850 _asmCmd changed to be more gplink and gpasm friendly
10851 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10852 produced an error when parsed, peep rule 12 is added to utilize
10853 movff, but it is commented out since the pCode does not support
10854 yet a command with 2 address arguments
10856 2003-05-18 <johan AT balder>
10858 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11989 bank zero as used by default. By default aslink locates the stack
11990 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11991 the creation of the .mem file. Delegates the allocation of data area
11992 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11993 the begining of the stack area to aslink.
11995 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11996 glue() in SDCCglue.c creates an area for it.
11998 2002-09-03 Borut Razem <borut.razem AT siol.net>
11999 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12000 sdcc/src/pic/glue.c:
12001 introduced atexit() handler for teporay files removal in case of
12002 errors, assertions, ...
12004 2002-08-29 Borut Razem <borut.razem AT siol.net>
12005 * sdcc/support/cpp2/auto-host_vc_in.h:
12006 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12007 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12008 Maybe there is a similar problem with BORLANDC? It should be checked!
12010 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12011 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12012 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12013 was not executed, and the compiler (cl) launched a warning:
12014 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12016 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12017 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12019 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12020 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12022 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12023 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12024 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12025 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12026 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12027 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12028 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12029 - added Release configuration in VS projects
12030 - review of compiler an linker options
12031 - VC .exe files are generated in bin_vc directory, not to interfere
12032 with binaries generated from other projects (cygwin, mingw, bcc ...)
12034 * sdcc/src/yacc.dsp: added
12036 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12037 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12038 and insert the version number definitions from .version
12040 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12042 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12043 added - genarate auto-host.h using auto-host_vc_in.h as template
12046 removed from CVS, generated automatically
12048 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12049 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12051 2002-08-11 Borut Razem <borut.razem AT siol.net>
12052 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12054 2002-08-10 Borut Razem <borut.razem AT siol.net>
12055 * src/SDCCmain.c (main):
12056 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12057 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12058 The consequence was that some temporary files were not removed.
12061 unification of code in functions tempfilename() and tempfile():
12062 function tempnam() is defined in Visual Studio 6.0 and .NET
12064 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12066 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12067 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12068 - removed compiler command line option /WX: Treats all warnings as errors
12069 - update a list of source files, included into the project
12071 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12072 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12073 changed project type to Generic Project so that can be correcly converted to VS.NET project
12075 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12077 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12079 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12081 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12082 added return 0 statements after assert() to make compiler happy
12084 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12085 added newline in the def file to keep MSC compiler satisfied
12087 * sdcc/src/z80/gen.c:
12088 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12089 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12090 - solved MSC error in function aopDump()
12092 * sdcc_vc.h: define PREFIX as "\\sdcc"
12094 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12095 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12143 Added -p option. Allows port dependent processor to be specified.
12146 Initialized the new field char *Processor field to NULL in all ports
12149 Compiler generated registers for interrupt context saving
12150 were not getting allocated.
12152 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12155 Fixed left shift. Will promote the left side of a left shift
12156 if a) left shifting more than size of operand or b) when assigned

12267 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12269 * sdcc/src/SDCCloop.c:
12270 Previous fix was not good. basic blocks that have "break" or "return" are
12271 not really partof a loop , but live ranges used in these blocks should
12272 be live thru the entire loop, so set partOfLoop but don't add them to
12275 2002-02-21 <johan AT FRIJA>
12277 * src/SDCCcse.c: fixed bug #514308
12279 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
