2039 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2041 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2042 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2044 One basic decision: e.g. src/clean.mk includes further files. In order
2045 to make this work there are two solutions:
2046 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2047 run configure on them. This way they can use
2048 'include $(srcdir)/port-clean.mk'
2049 - always include clean.mk by the Makefile at the same level. To avoid
2050 that `make clean` tries to include and build Makefile.dep the
2051 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2052 implemented, because now even `make uninstall` doesn't create
2053 Makefile.in. clean.mk could be eliminated by pasting it in
2056 * debugger/mcs51/Makefile.in: build own objects from library sources
2057 (SLIB, SDCC) in current directory
2059 * configure, configure.in: renamed --disable-device-lib-build in
2060 --disable-device-lib; added --enable-doc, the required tools are
2061 searched by configure; added result message; the toolchain for the
2062 belonging ports are now only built, if the port is enabled.
2064 * support/regression/*: all output is written in directory gen, because
2065 the fwk and ports directories don't livet in the build tree using vpath
2067 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2068 --disable-device-lib, added --enable-doc, added section VPATH
2070 * sim/ucsim/configure.in,
2071 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2072 z80 are enabled by default
2074 2006-04-24 Raphael Neider <rneider AT web.de>
2076 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2077 to config word, "pic14_"-prefixed some extern functions
2078 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2079 config word has been found
2080 * src/pic/device.h: added prototypes
2081 * src/pic/pcode.c: added "pic14_"-prefix where needed
2082 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2084 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2087 (pic14createInterruptVect): moved generating __config directives away

2099 (pCodeRegOptimizeRegUsage): fixed typo in comment

2103 * device/examples/main8051.c: deleted - it was removed from CVS

2345 implemented patch 1120823 Thanks to Willy De la Court (normal
2346 interrupts need an interrupt number now if they are made critical),
2347 and enabled nesting of critical functions though not for gbz80
2348 (genCritical, genEndCritical): added functions
2349 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2350 * src/z80/mappings.i: added "ei" to all mappings

2362 the left operand is shorter than the result (c* = lit-c* + int),
2364 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2367 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2369 * src/.version: increased version number to 2.5.5
2370 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2371 linking is done manually in pic16 port's _linkEdit,
2372 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2373 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2374 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2375 allocate asmop as AOP_ACC,
2376 (aopForRemat): added parameter 'bool result' in function declaration,
2377 (pic16_aopGet): return AOP_ACC when accessing WREG,
2378 (pic16_popGetTempReg): minor modification,

2389 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2390 call to allocReg, not by manually allocating a new one,
2391 (pic16_assignRegisters): now before going through the register
2392 allocating functions mark all registers as free. This eliminates some
2393 side effects resulting from peephole parser done earlier in the backbone
2395 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2453 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2454 which dumps before the function entry point a data byte which represents
2455 the number of the local variables used by the specified function, added
2456 'xinst' for initial support for Extended Instruction Support,
2457 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2458 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2459 port->fun_prefix anymore (may change later),
2460 (genFunction, genEndFunction): do not store/restore local registers for
2461 _main (this should take care the --main-return command line option in
2463 (genOr): removed some legacy pic-port instructions,
2464 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2465 performing operations with SFR's causes data to be written more than
2466 once to each SFR. Perhaps SFRs should be handled in special cases...
2467 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2469 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2470 into account for stack starting position,

2472 --extended or -y for Extended Instruction Support,
2473 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2474 (deassignLRs): *** perhaps the most important change, old 'for' code
2475 (commented out for reference), didn't account for some registers which
2476 were left marked 'not free' after a pointer operation. The change
2477 reduces register usage a lot in some cases
2479 2006-03-04 Borut Razem <borut.razem AT siol.net>
2481 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4744 on rIfx (genCmp was broken)
4746 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4748 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4749 * src/z80/main.c (_keywords[]),
4750 * src/SDCCglobal.h (struct options),
4752 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4753 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4754 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4755 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4756 always available in leading double underscore form. The C99 support is
4757 mostly missing, but it's a start.
4758 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4759 reserved identifier "__data".
4761 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4807 2005-03-20 Borut Razem <borut.razem AT siol.net>
4809 * support/scripts/inc2h.pl: WIN32 port

4837 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4839 * device/lib/printf_large.c: removed inline assembly for portability and
4840 readability. Use printf_fast if speed or size are more important.
4841 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4842 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4844 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4846 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4847 prevent compiler warning
4849 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4851 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4852 moved to level 0 and declared as static. Also they are explicit
4853 placed in access bank. This was necessery because some times they
4854 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4855 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4856 optimizations. Currently only compare to unsigned char is implemented,
4857 * src/pic16/gen.c: added fReturnIdx array,
4858 * (struct resolvedIfx) is moved to gen.h and made public,
4859 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4860 * (aopForSym): added an optimization to directly store in stack of
4861 the operand of a SEND iCode,
4862 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4863 but as registers instead (AOP_REG) using the fReturnIdx array,
4864 * (pic16_freeAsmop): remove the freed register from the
4865 _G.sregsAlloc field,
4866 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4867 a compare of 'WREG',
4868 * (pic16_popGetTempRegCond): changed function prototype, now
4869 function takes also a bitVector argument v which holds the current
4870 set of registers that are allocated for stack access by aopForSym,
4871 registers allocated in aopForSym for accessing stack symbols are not
4872 any more part of the functions usedRegs field,
4873 * (genCall): some times aopOp is called for a stack variable to be
4874 send, aopForSym might perform the push, if this is true make sure
4875 that genCall doesn't push the variable twice by testing _G.resDirect,
4876 * (genFunction): changed testing for unspecified interrupt number
4877 from 256 to INTNO_UNSPEC,
4878 * modified selection scheme of frame pointer generation. Previously
4879 if function did use local registers a frame pointer was generated,
4880 now a frame pointer is generated only if function has arguments
4881 (that need PLUSW2 register access), or has stack arguments, or the
4882 compiler is not instructed to omit the frame pointer,
4883 * (genEndFunction): before restoring local registers that were saved
4884 in the function preamble, also restore the registers that *might*
4885 have been allocated for stack access,
4886 * (genRet): removed some old comments,
4887 * (genCmp, the active (RN's) version): added a call to the
4888 pic16_genCmp_special function to perform the compare with a more
4889 robust and optimized way,
4890 * (genInline): a feature has been added in inline code generation,
4891 which allows a wildcard variable substitution when writing inline
4892 assembly. Code is incomplete and experimental therefore undocumented,
4893 * (genCast): changed order of aopOp for result and right to allow
4894 aopForSym to directly load the result if possible,
4895 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4896 perform an optimized compare on some selected special occasions,
4897 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4898 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4899 generate an IVT any more,
4900 * src/pic16/main.c (pic16_optionsTable): added command line option
4902 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4903 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4905 * src/pic16/NOTES: Raphael Neider added in list of active developers
4906 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4907 jumptable_end to prevent bug #,
4908 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4909 inCond and outCond fields,
4910 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4911 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4912 turn off register spilling,
4913 * (packRegsForOneUse): synced with other ports' versions although it
4914 is not used currently,
4915 * (pic16_packRegisters): added an optimization while reading
4916 structure bitfields, some registers may be saved (malloc code is
4917 decreased by 80 bytes)
4919 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4921 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4922 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4923 this can be optimized more?
4925 2005-03-10 Raphael Neider <rneider AT web.de>
4927 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4928 genNearPointerGet): (hopefully) fixed access to bitfields via
4929 pointers (p->bitN = x; and x = p->bitN; failed)
4931 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4933 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4974 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4975 to keep the correct label reference count when adding/removing references
4976 to labels. A peephole file using this is appended to patch #1144962.

5108 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5109 (sizeof(sectNames) changed to sizeof(sectName))
5110 Both patches fix segfaults under MinGW.
5112 2005-01-23 Raphael Neider <rneider AT web.de>

5115 Safe_[mc]?alloc()'ed variables
5116 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5117 of (byte sized) temporaries (assign them to WREG for now)
5118 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5119 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5120 this might fix SIGSEGVs on MinGW...
5121 * src/SDCCopt.c (killDeadCode): restored original behaviour
5122 (volatile operands might get thrown away though)
5124 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
5126 * src/pic16/gen.c: fixed bug #1106975,

5131 * added function attribute 'shadowregs' to take advantage of shadow
5133 * added function attribute 'wparam' as an alternative to the wparam
5135 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
5136 user declares a non-ISR function as 'shadowregs',
5137 * doc/sdccman.lyx: updated to reflect recent changes of pic16 port

5578 * support/regression/tests/bug1057979.c: added test for bug 1073386
5580 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
5582 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
5585 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
5587 * src/pic16/device.h,
5588 * src/pic16/genarith.c,
5591 * src/pic16/pcode.c: applied patches #1068154 and #1070213
5593 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
5595 Large cummulative patch for pic16 port.
5596 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5597 to call when a stack overflow occurs,
5598 * (malloc.h): added CVS Id tag,
5599 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5601 * added libc directory. The current version of LibC contains string
5602 functions, ctype functions and macros and some functions of the
5603 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5604 be extensively tested in the future. Standard disclaimer here.
5605 Library is not automatically build yet. But one can build it by
5606 invoking 'make' inside the libc directory.
5607 * added ADC library under libio. Preliminary version yet.
5609 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5610 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5611 aopForRemat() now and not by pic16_aopOp(),
5612 * (pic16_popGetTempReg): removed warning messgae when allocating
5613 temporary registers, its a buggy feature and will be removed,
5614 * (pic16_popGet): set register instance field in AOP_CRY,
5615 * (pic16_outBitC): fixed for results in size greater than 1,
5616 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5617 * (pic16_storeForReturn): optimized return of 0,
5618 * (genCmp): experimental code for new genCmp which uses PIC18's
5619 special compare&skip instructions. Initial tests fail some times
5620 with variables grater than 1 byte in size, so new code is disabled,
5621 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5623 * (genCast): began a fix to optimize the casting of a bit to another
5624 bit, now assigning a bitfield to another bitfield will fail, sorry,
5625 * src/pic16/main.c: disabled the use of lr-support feature,
5626 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5627 * added some function prototypes, added function _debugf prototype,
5628 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5629 bits with offset (case PO_GPR_BIT),
5630 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5632 * (isBankInstruction): modified to return 0 for no banking instruction,
5633 and 1 for banking instruction,
5634 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5635 caused stop processing pCodes after a inline assembly block,
5636 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5637 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5638 registers when it shouldn't,
5639 * src/pic16/ralloc.c (allocReg): add preliminary support for
5640 supporting a limited set of temporary registers,
5642 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5644 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5645 genDataPointerSet): ensure assignments always copy in MSB to LSB
5647 (loadRegFromAop): recognize CLRH optimization,
5648 (genFunction): optimize RECEIVE iCodes in reentrant functions
5650 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5652 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5653 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
5655 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5661 * device/lib/_gptrget.c (_gptrget),
5662 * device/lib/_gptrgetc.c (_gptrgetc),
5663 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5664 instead of sjmp to ret
5665 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5666 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

8647 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8649 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8650 loaded with the linker search paths (-L arguments) and the libraries
8651 to be linked with the current source (-l arguments). Changes
8652 currently will affect only the pic16 port.
8653 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8654 include path the port specific paths and port specific libraries,
8655 * gplink command now contains the $3 argument,
8656 * src/pic16/device.h,
8657 * src/pic16/device.c,: structure PIC_device is made public and
8658 renamed to PIC16_device, the same for variable Pics which is renamed

8673 Documenting changes from previous commits.
8674 * configure.in (version 1.56),
8675 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8676 when generating output files to configure the pic16 library,
8677 but now I've commented it out, since gputils aren't installed in the
8678 SF compile farm, so library won't compile
8680 * device/lib/Makefile.in (version 1.56): initially I've added in
8681 target 'all' the prerequestive 'model-pic16' so it compiled the
8682 pic16 library, but now I've commented it out for the same reasons
8684 * added targets 'model-pic16' and 'objects-pic16' to compile the
8686 * added target 'port-specific-objects-pic16' to handle the
8687 generated libraries and copy them into the build/ directory
8688 * added target 'clean-intermediate-pic16' to clean intermediate
8689 files into pic16 directory
8690 * in target 'installdirs' added line to create directory pic16 in

8711 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8712 option so that it actually works. Made it specific to the z80, since
8713 the gbz80 doesn't have these kinds of I/O ports.
8715 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8717 * device/include/z180.h,

8741 via literal number. The symbol is placed in the corresponding
8742 position of the data ram
8743 * (pic16_dump_section): relocatable and absolute uninitialized
8744 data are now emitted in sorted order to reduce section naming,
8745 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8746 weren't marked as being in the access bank,
8748 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8750 Added portion of GNU PIC Library under the directory
8751 device/include/pic16 and device/lib/pic16. These files
8752 contain the declarations of SFRs for the PIC18Fxx2 devices.
8753 The directory is initialized via configure from toplevel.
8755 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8757 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8758 the spilllocations to be compared correctly

8782 * doc/sdccman.lyx: Moved and added some sections, small changes
8783 all over. Telling LaTeX to be less strict with word spacing
8784 to better keep the right margin. Changed some notes about
8785 maintainance of the ports in section 3.2.1 - is it OK like this?
8787 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8825 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8827 * src/pic16/peeph.def: all peepholes with movff are commented out,
8828 because there is a problem in the pcode peep optimizer,
8829 * src/pic16/ralloc.c: the register allocator can now reuse local

8831 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8833 Added file src/pic16/NOTES with information about program writing on
8834 the current port version.

8866 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8869 * src/z80/main.c: added missed needLinkerScript flags (more than
8870 one port structure defined in these file)
8871 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8887 needLinkerScript flag
8889 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8890 * src/pic/glue.c: added variable udata_section_name to
8891 override default uninitialized data segment definition for
8892 devices only with SHAREBANK memory (reported from Erik Epetrich)
8893 * (pic14emitOverlay): modified to emit a commented overlay segment
8894 directive when no overlay data exist
8895 * (picglue): modified to emit uninitialized data segment
8896 according to udata_section_name

8906 2004-01-07 Borut Razem <borut.razem AT siol.net>
8908 * support/scripts/sdcc.nsi: update PATH
8909 * support/scripts/sdcc.ico: craeted

8916 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8918 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8920 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8922 include information about variables allocated to the overlay
8925 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8927 * as/mcs51/lkmain.c: Help about -Y option

8939 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8941 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8942 (default behaviour).
8944 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8946 A python script to validate compiler diagnostic messages. It can be
8947 used to verify that sdcc complains about bad c source code and
8948 gives a good location of the error.
8949 * support/valdiag/Makefile,
8950 * support/valdiag/valdiag.py,
8951 * support/valdiag/tests/*
8953 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8955 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8966 * src/common.h: added ifndef/define/endif macros
8967 around the header file.
8968 Bug reported from Jesus Calvino-Fraga
8970 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8972 * sdcc.spec: updated
8973 * device/include/Makefile.in: don't install CVS directories
8974 * device/lib/Makefile.in: added removal of CVS directories after install
8975 * doc/Makefile: fixed install, added local_icons
8976 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8977 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8978 * src/ds390/gen.c (genRightShift): fixed bug #870788
8979 * src/SDCCast.c (decorateType): fixed bug #870781
8981 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8983 PIC16 port related changes:
8984 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8985 added variable stackPos,
8987 * gen.c: genCall, assignResultValue: added support for
8988 pushing/retrieving function parameters to/from stack,
8989 genFunction,genEndFunction: setup stack frame for the
8991 genAddrOf: will be changed according to bug 863624
8993 * added files genutils.c and genutils.h which contain gen*
8994 debugged and optimised functions extracted from gen.c
8996 * glue.c: added variable 'externs' which holds extern symbols,
8997 pic16emitRegularMap: is modified to properly handle relocatable
8998 symbols under the new scheme,
8999 pic16createInterruptVect: is modified
9000 pic16printPublics: is modified to emit 'global' assembler directives,
9001 added pic16_printExterns to print extern symbols,
9002 pic16glue: initializes stack/frame pointer in the beginning of
9003 the assembly output. Temporary hack, will be corrected later,
9004 because gplink yet does not support stack and SDCC does not
9005 yet support a type of crt0.o object to create the final binary.
9007 * Removed many lines that contain 8051 legacy code.
9008 * The code is finally placed under a 'code' directive.
9009 * Added port specific options.
9011 * _process_pragma: simplified since now we do not need *special*
9012 include file to define SFR registers. But a separate header
9013 will be needed. This will be developed later.
9014 * _pic16_parseOptions: added, parses port specific options:
9015 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9016 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9017 --preplace-udata-with=
9019 * _pic16_setDefaultOptions: modified to initialize section names,
9020 but hack is temporarly out of order since it needs improvement.
9021 * _pic16_genAssemblerPreamble: configuration words are emitted by
9022 their address instead of their name. This part is incomplete and
9023 supports only the 18Fxx2 devices. Other devices will emit an error
9024 during assembly since they do not contain the same set of config
9026 * _pic16_genIVT: is modified,
9028 * pcode.c: added definitions for some hardware registers that are needed
9030 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9031 All PCI entries are updated. Now LFSR is supported.
9032 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9033 * added pic16_newpCodeOpLit2 to support instructions with
9034 two literal arguments
9035 * pic16_pCode2str: corrected code that emits assembler instructions
9036 with two literal operands and those that have an access bit modifier
9037 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9038 this fixes a bug which caused some labels to be lost, when an
9039 assembler directive was added, i.e. banksel,
9040 * pic16_FixRegisterBanking: improved logic that causes the insertion
9042 * InlineFunction: functions that are called once, are not any more
9043 inlined. This can be a port option in the future,
9045 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9047 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9048 hold the corresponding uninitialized symbols,
9049 * pic16_allocProcessorRegister: registers have explicit marked the
9051 * pic16_allocInternalRegister: registers are explicit marked as
9053 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9054 processing list, so bit registers were lost,
9057 * ralloc.h: added field 'accessBank' and original symbol operand
9058 in register definition,
9059 * removed the field isMapped from register definition,
9061 ** Several functions have been removed from various sources:
9062 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9063 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9064 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9065 pic16_assignRelocatableRegisters
9067 ** others have been introduced:
9068 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9069 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9071 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9073 * support/scripts/inc2h.pl: changed definition of BIT_AT
9074 to emit 'sbit at' instead of 'bit at'. This was a request.
9076 PIC16 port related preliminary changes:
9077 * gen.c: prefixed function popRegFromString with
9078 pic16_ and all references to it corrected
9079 * pcode.c: all pic16_pc_* hardware registers prefixed
9080 with underscore (_),
9081 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9082 * ralloc.c: newReg(): when register is REG_SFR then
9083 set address to rIdx,
9084 pic16_allocProcessorRegister(): marks register wasUsed=0
9085 pic16_writeUsedRegs(): added a call to assign processor
9086 registers via pic16_assignFixedRegisters
9088 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9090 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9091 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9092 variables in unused register banks. Also the SSEG is placed
9093 wherever there is enough space for it, and IDATA can be anywhere
9094 in internal RAM. For now compile using -Wl-Y[stack_size].
9095 The mem file is different for this option as well, since it
9096 makes no sense of talking about DSEG lenght.
9098 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9100 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9101 in certain cases, e.g. when ROM assignment, patch provided
9102 from Albert den Haan.
9104 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9649 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9651 Fixed a number of problems revealed by bug #827883.
9652 * src/SDCCloop.c (loopInvariants): Spill location of the
9653 result operand should be recomputed if extracted from
9654 a loop. Also, don't extract assignments of an iTemp

9657 not occur if the control variable is involved with a
9658 relational operator.

10151 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10153 Try to make the peephole optimizer smarter by maintaining
10154 an association between the assembly source code and the
10155 iCodes that originated them. Put this information to use
10156 with a new peephole rule condition "notVolatile" so that
10157 the rules can be aggressive yet still safe.
10162 * src/mcs51/peeph.def
10164 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10172 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10174 Changed the type of the result of the ! (NOT) operator to char;
10175 previously it returned the same type as the source. This allows
10176 us to eliminate all the genFloatNot functions (all of its target
10177 implementations were very buggy) since !float can use the same
10180 * src/SDCCicode.c (ast2iCode): ! returns char
10181 * src/mcs51/gen.c (genNot, genNotFloat),
10182 * src/ds390/gen.c (genNot, genNotFloat),
10183 * src/z80/gen.c (genNot, genNotFloat),

10185 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
10187 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
10189 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10190 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10191 during interrupts. Ensure WSAVE is located at a shared bank address.
10192 2. Fixed page selection in some places
10193 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10194 the registers name strings.
10195 4. Fixed "signed / unsigned compare" compiler warnings.
10196 5. The PIC port manages its own allocation of the general purpose
10197 registers, but makes no attempt to reuse them. As a result when
10198 compiling it soon runs out of general purpose registers. Some
10199 additional code was added to the files pcode.c and device.c to walk
10200 through the function call tree and rename the registers so that they
10210 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10211 genPlus() & genMinus() when the result is the same as left or right

10217 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10219 Made bitfield a distinct type from bit so that bitfields
10220 convert as per ANSI C and bits retain their traditional
10221 boolean style behaviour. Implemented bitfield support in
10229 * src/ds390/gen.c: bit v bitfield split
10230 * src/z80/gen.c: New support for bitfields
10231 * support/regression/tests/bitfields.c: reenabled z80,
10234 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10236 Rules 246.x, 247.x relate to bitfields, the others speed up
10237 access to xdata mapped I/O devices.
10239 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10241 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10243 Cleaned up genPackBits and genUnpackBits and added two helper
10244 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10245 for literal assignments in genPackBits (thanks to Frieder for
10251 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10253 Fixed bug #748310 (pointer to function type mishandled when the
10254 function name is omitted). Also fixed a SIGSEGV when a function
10255 attribute (reentrant, etc) is used on a non-function or on a
10256 function but misplaced before the parameter list.
10258 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10260 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

10283 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10285 Made the constant following the "interrupt" keyword optional. If
10286 omitted, the function will not automatically be given an entry
10287 in the interrupt vector table (similar to #pragma NOIV, but
10288 less syntacticly kludgy). The interrupt number is also now
10289 range checked. Also fixed a bug in the high order bit example

10308 be re-activated by defining REDUCE_LITERALS)
10309 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10310 unsigned, but are signed by default
10311 * src/SDCCval.c (constVal): rearranged
10312 * src/SDCCval.c (valMod): preliminary fix

10765 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10766 the regression tests I'm not brave enough to enable 245.b, 245.c
10767 * doc/sdccman.lyx: added latex preamble for hyperref package.
10768 Using pdflatex this will give you a hyperlinked pdf file with
10769 bookmarks. (prepend '%' before /usepackage if this breaks something)

10819 added if/endif conditional macros to remove options help
10820 messages from optionsTable when a port is not configured, added
10821 support for the PIc16 port in the ports table, when executing
10822 the compiler with no port specified on command line, a default
10823 port is selected with the new macro DEFAULT_PORT which is
10824 defined in port.h, in setDefaultOptions() linkOptions is removed
10825 from initialization assignment, since now it is a set,
10826 parseCmdLine uses setParseWithComma for linkOptions, in
10827 linkEdit() linkOptions are accessed with new function indexSet()
10828 which returns the i'th item of a set variable. See SDCCset.c, in
10829 linkEdit() when calling buildCmdLine(), added linkOptions as
10830 last argument. Now users can pass arguments to gplink via the
10831 -Wl option, main() uses pic16glue() to glue up pic16 programs
10832 * src/SDCCpeeph.c: various changes to support pic16
10833 * src/SDCCset.c: added function void *indexSet(set *, int) to

10843 * src/pic16/glue.c: commented out some error producing lines
10844 * src/pic16/main.c: __config directives are commented out to stop
10845 gpasm complaining and test the linkage with gplink, _linkCmd and
10846 _asmCmd changed to be more gplink and gpasm friendly
10847 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10848 produced an error when parsed, peep rule 12 is added to utilize
10849 movff, but it is commented out since the pCode does not support
10850 yet a command with 2 address arguments
10852 2003-05-18 <johan AT balder>
10854 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11919 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11920 following files to include the previous two files: aslink.dsp,
11921 Makefile.aslink, Makefile.bcc, and Makefile.in.
11923 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11924 .adb instead of .cdb
11926 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11928 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the

11940 packRegsForAccUse() (bug 542397)
11941 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11942 multiple times and emitting the fetch operations more than once
11943 added aopGetUsesAcc() function to allow binary operators to
11944 fetch their operands in the correct order; made genMinus() emit
11945 compact code for X = LITERAL - Y

11956 Changes to aslink (All the changes are marked with 'JCF'):
11958 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11961 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11962 area BSEG. Also moves, if possible, the DATA area down into the internal
11963 ram so more space is available.
11965 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11968 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11969 not bytes. Function summary() which creates a memory usage summary
11970 file with extension .mem. Reports of overlaping stack and small stack
11971 size. If the space for the stack is less than 16 bytes aslink trows a
11974 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11975 the 8051. Option 'y' for memory summary output file.
11977 Changes to sdcc (All the changes are marked with 'JCF'):
11979 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11981 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11982 overlaying area for it (uses RegBankUsed[4]).
11984 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11985 bank zero as used by default. By default aslink locates the stack
11986 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11987 the creation of the .mem file. Delegates the allocation of data area
11988 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11989 the begining of the stack area to aslink.
11991 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11992 glue() in SDCCglue.c creates an area for it.
11994 2002-09-03 Borut Razem <borut.razem AT siol.net>
11995 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11996 sdcc/src/pic/glue.c:
11997 introduced atexit() handler for teporay files removal in case of
11998 errors, assertions, ...
12000 2002-08-29 Borut Razem <borut.razem AT siol.net>
12001 * sdcc/support/cpp2/auto-host_vc_in.h:
12002 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12003 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12004 Maybe there is a similar problem with BORLANDC? It should be checked!
12006 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12007 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12008 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12009 was not executed, and the compiler (cl) launched a warning:
12010 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12012 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12013 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12015 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12016 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12018 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12019 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12020 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12021 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12022 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12023 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12024 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12025 - added Release configuration in VS projects
12026 - review of compiler an linker options
12027 - VC .exe files are generated in bin_vc directory, not to interfere
12028 with binaries generated from other projects (cygwin, mingw, bcc ...)
12030 * sdcc/src/yacc.dsp: added
12032 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12033 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12034 and insert the version number definitions from .version
12036 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12038 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12039 added - genarate auto-host.h using auto-host_vc_in.h as template
12042 removed from CVS, generated automatically
12044 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12045 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12047 2002-08-11 Borut Razem <borut.razem AT siol.net>
12048 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12050 2002-08-10 Borut Razem <borut.razem AT siol.net>
12051 * src/SDCCmain.c (main):
12052 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12053 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12054 The consequence was that some temporary files were not removed.
12057 unification of code in functions tempfilename() and tempfile():
12058 function tempnam() is defined in Visual Studio 6.0 and .NET
12060 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12062 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12063 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12064 - removed compiler command line option /WX: Treats all warnings as errors
12065 - update a list of source files, included into the project
12067 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12068 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12069 changed project type to Generic Project so that can be correcly converted to VS.NET project
12071 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12073 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12075 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12077 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12078 added return 0 statements after assert() to make compiler happy
12080 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12081 added newline in the def file to keep MSC compiler satisfied
12083 * sdcc/src/z80/gen.c:
12084 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12085 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12086 - solved MSC error in function aopDump()
12088 * sdcc_vc.h: define PREFIX as "\\sdcc"
12090 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12091 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12263 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12265 * sdcc/src/SDCCloop.c:
12266 Previous fix was not good. basic blocks that have "break" or "return" are
12267 not really partof a loop , but live ranges used in these blocks should
12268 be live thru the entire loop, so set partOfLoop but don't add them to
12271 2002-02-21 <johan AT FRIJA>
12273 * src/SDCCcse.c: fixed bug #514308
12275 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
