2070 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2072 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2073 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2075 One basic decision: e.g. src/clean.mk includes further files. In order
2076 to make this work there are two solutions:
2077 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2078 run configure on them. This way they can use
2079 'include $(srcdir)/port-clean.mk'
2080 - always include clean.mk by the Makefile at the same level. To avoid
2081 that `make clean` tries to include and build Makefile.dep the
2082 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2083 implemented, because now even `make uninstall` doesn't create
2084 Makefile.in. clean.mk could be eliminated by pasting it in
2087 * debugger/mcs51/Makefile.in: build own objects from library sources
2088 (SLIB, SDCC) in current directory
2090 * configure, configure.in: renamed --disable-device-lib-build in
2091 --disable-device-lib; added --enable-doc, the required tools are
2092 searched by configure; added result message; the toolchain for the
2093 belonging ports are now only built, if the port is enabled.
2095 * support/regression/*: all output is written in directory gen, because
2096 the fwk and ports directories don't livet in the build tree using vpath
2098 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2099 --disable-device-lib, added --enable-doc, added section VPATH
2101 * sim/ucsim/configure.in,
2102 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2103 z80 are enabled by default
2105 2006-04-24 Raphael Neider <rneider AT web.de>
2107 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2108 to config word, "pic14_"-prefixed some extern functions
2109 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2110 config word has been found
2111 * src/pic/device.h: added prototypes
2112 * src/pic/pcode.c: added "pic14_"-prefix where needed
2113 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2115 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2118 (pic14createInterruptVect): moved generating __config directives away

2128 registers that have not been assigned proper liveranges,
2129 fixes #1469504 and #1474602,
2130 (pCodeRegOptimizeRegUsage): fixed typo in comment
2132 2006-04-24 Borut Razem <borut.razem AT siol.net>
2134 * device/examples/main8051.c: deleted - it was removed from CVS
2135 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2136 after the transition to Subversion
2137 * src/SDCCalloc.h: deleted - it was removed from CVS
2138 3.feb.2001 and after that modified 18.feb.2001, so it reappered

2376 implemented patch 1120823 Thanks to Willy De la Court (normal
2377 interrupts need an interrupt number now if they are made critical),
2378 and enabled nesting of critical functions though not for gbz80
2379 (genCritical, genEndCritical): added functions
2380 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2381 * src/z80/mappings.i: added "ei" to all mappings

2393 the left operand is shorter than the result (c* = lit-c* + int),
2395 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2398 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2400 * src/.version: increased version number to 2.5.5
2401 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2402 linking is done manually in pic16 port's _linkEdit,
2403 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2404 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2405 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2406 allocate asmop as AOP_ACC,
2407 (aopForRemat): added parameter 'bool result' in function declaration,
2408 (pic16_aopGet): return AOP_ACC when accessing WREG,
2409 (pic16_popGetTempReg): minor modification,

2420 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2421 call to allocReg, not by manually allocating a new one,
2422 (pic16_assignRegisters): now before going through the register
2423 allocating functions mark all registers as free. This eliminates some
2424 side effects resulting from peephole parser done earlier in the backbone
2426 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2484 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2485 which dumps before the function entry point a data byte which represents
2486 the number of the local variables used by the specified function, added
2487 'xinst' for initial support for Extended Instruction Support,
2488 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2489 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2490 port->fun_prefix anymore (may change later),
2491 (genFunction, genEndFunction): do not store/restore local registers for
2492 _main (this should take care the --main-return command line option in
2494 (genOr): removed some legacy pic-port instructions,
2495 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2496 performing operations with SFR's causes data to be written more than
2497 once to each SFR. Perhaps SFRs should be handled in special cases...
2498 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2500 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2501 into account for stack starting position,

2503 --extended or -y for Extended Instruction Support,
2504 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2505 (deassignLRs): *** perhaps the most important change, old 'for' code
2506 (commented out for reference), didn't account for some registers which
2507 were left marked 'not free' after a pointer operation. The change
2508 reduces register usage a lot in some cases
2510 2006-03-04 Borut Razem <borut.razem AT siol.net>

4777 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4779 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

4783 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4784 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4785 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4786 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4787 always available in leading double underscore form. The C99 support is
4788 mostly missing, but it's a start.
4789 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4790 reserved identifier "__data".
4792 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4838 2005-03-20 Borut Razem <borut.razem AT siol.net>
4840 * support/scripts/inc2h.pl: WIN32 port

4868 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4870 * device/lib/printf_large.c: removed inline assembly for portability and
4871 readability. Use printf_fast if speed or size are more important.
4872 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4873 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4875 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4877 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4878 prevent compiler warning
4880 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4882 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4883 moved to level 0 and declared as static. Also they are explicit
4884 placed in access bank. This was necessery because some times they
4885 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4886 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4887 optimizations. Currently only compare to unsigned char is implemented,
4888 * src/pic16/gen.c: added fReturnIdx array,
4889 * (struct resolvedIfx) is moved to gen.h and made public,
4890 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4891 * (aopForSym): added an optimization to directly store in stack of
4892 the operand of a SEND iCode,
4893 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4894 but as registers instead (AOP_REG) using the fReturnIdx array,
4895 * (pic16_freeAsmop): remove the freed register from the
4896 _G.sregsAlloc field,
4897 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4898 a compare of 'WREG',
4899 * (pic16_popGetTempRegCond): changed function prototype, now
4900 function takes also a bitVector argument v which holds the current
4901 set of registers that are allocated for stack access by aopForSym,
4902 registers allocated in aopForSym for accessing stack symbols are not
4903 any more part of the functions usedRegs field,
4904 * (genCall): some times aopOp is called for a stack variable to be
4905 send, aopForSym might perform the push, if this is true make sure
4906 that genCall doesn't push the variable twice by testing _G.resDirect,
4907 * (genFunction): changed testing for unspecified interrupt number
4908 from 256 to INTNO_UNSPEC,
4909 * modified selection scheme of frame pointer generation. Previously
4910 if function did use local registers a frame pointer was generated,
4911 now a frame pointer is generated only if function has arguments
4912 (that need PLUSW2 register access), or has stack arguments, or the
4913 compiler is not instructed to omit the frame pointer,
4914 * (genEndFunction): before restoring local registers that were saved
4915 in the function preamble, also restore the registers that *might*
4916 have been allocated for stack access,
4917 * (genRet): removed some old comments,
4918 * (genCmp, the active (RN's) version): added a call to the
4919 pic16_genCmp_special function to perform the compare with a more
4920 robust and optimized way,
4921 * (genInline): a feature has been added in inline code generation,
4922 which allows a wildcard variable substitution when writing inline
4923 assembly. Code is incomplete and experimental therefore undocumented,
4924 * (genCast): changed order of aopOp for result and right to allow
4925 aopForSym to directly load the result if possible,
4926 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4927 perform an optimized compare on some selected special occasions,
4928 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4929 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4930 generate an IVT any more,
4931 * src/pic16/main.c (pic16_optionsTable): added command line option
4933 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4934 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4936 * src/pic16/NOTES: Raphael Neider added in list of active developers
4937 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4938 jumptable_end to prevent bug #,
4939 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4940 inCond and outCond fields,
4941 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4942 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4943 turn off register spilling,
4944 * (packRegsForOneUse): synced with other ports' versions although it
4945 is not used currently,
4946 * (pic16_packRegisters): added an optimization while reading
4947 structure bitfields, some registers may be saved (malloc code is
4948 decreased by 80 bytes)
4950 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4952 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4953 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4954 this can be optimized more?
4956 2005-03-10 Raphael Neider <rneider AT web.de>
4958 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4959 genNearPointerGet): (hopefully) fixed access to bitfields via
4960 pointers (p->bitN = x; and x = p->bitN; failed)
4962 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5005 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5006 to keep the correct label reference count when adding/removing references
5007 to labels. A peephole file using this is appended to patch #1144962.

5139 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5140 (sizeof(sectNames) changed to sizeof(sectName))
5141 Both patches fix segfaults under MinGW.
5143 2005-01-23 Raphael Neider <rneider AT web.de>

5146 Safe_[mc]?alloc()'ed variables
5147 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5148 of (byte sized) temporaries (assign them to WREG for now)
5149 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5150 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5151 this might fix SIGSEGVs on MinGW...
5152 * src/SDCCopt.c (killDeadCode): restored original behaviour
5153 (volatile operands might get thrown away though)

5581 comparisons, and supports quoted literals
5582 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
5584 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5592 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5594 Adding support for replacing ljmps with sjmps in jumptables
5595 generated for switch statements. For now you need to set the
5596 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5597 Now 4 algorithms for mcs51 jumptable generation are used:
5598 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5599 addresses loaded pc-relative for up to 112 cases and stack-pushing
5600 target addresses loaded with offset from dptr for up to 256 cases.
5602 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5603 * src/mcs51/main.c: adapted constants for switch table generation
5604 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

5624 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
5626 Large cummulative patch for pic16 port.
5627 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5628 to call when a stack overflow occurs,
5629 * (malloc.h): added CVS Id tag,
5630 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5632 * added libc directory. The current version of LibC contains string
5633 functions, ctype functions and macros and some functions of the
5634 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5635 be extensively tested in the future. Standard disclaimer here.
5636 Library is not automatically build yet. But one can build it by
5637 invoking 'make' inside the libc directory.
5638 * added ADC library under libio. Preliminary version yet.
5640 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
5641 * src/pic16/gen.c (aopForRemat): asmop size is filled by
5642 aopForRemat() now and not by pic16_aopOp(),

5644 temporary registers, its a buggy feature and will be removed,
5645 * (pic16_popGet): set register instance field in AOP_CRY,
5646 * (pic16_outBitC): fixed for results in size greater than 1,
5647 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5648 * (pic16_storeForReturn): optimized return of 0,
5649 * (genCmp): experimental code for new genCmp which uses PIC18's
5650 special compare&skip instructions. Initial tests fail some times
5651 with variables grater than 1 byte in size, so new code is disabled,
5652 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5654 * (genCast): began a fix to optimize the casting of a bit to another
5655 bit, now assigning a bitfield to another bitfield will fail, sorry,
5656 * src/pic16/main.c: disabled the use of lr-support feature,
5657 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5658 * added some function prototypes, added function _debugf prototype,
5659 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
5660 bits with offset (case PO_GPR_BIT),
5661 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5663 * (isBankInstruction): modified to return 0 for no banking instruction,
5664 and 1 for banking instruction,
5665 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5666 caused stop processing pCodes after a inline assembly block,
5667 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5668 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5669 registers when it shouldn't,
5670 * src/pic16/ralloc.c (allocReg): add preliminary support for
5671 supporting a limited set of temporary registers,
5673 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5675 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5676 genDataPointerSet): ensure assignments always copy in MSB to LSB
5678 (loadRegFromAop): recognize CLRH optimization,
5679 (genFunction): optimize RECEIVE iCodes in reentrant functions
5681 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5683 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
5684 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

5693 * device/lib/_gptrgetc.c (_gptrgetc),
5694 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
5695 instead of sjmp to ret
5696 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
5697 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5699 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8682 to be linked with the current source (-l arguments). Changes
8683 currently will affect only the pic16 port.
8684 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8685 include path the port specific paths and port specific libraries,
8686 * gplink command now contains the $3 argument,
8687 * src/pic16/device.h,
8688 * src/pic16/device.c,: structure PIC_device is made public and
8689 renamed to PIC16_device, the same for variable Pics which is renamed
8690 to Pics16. Updated all references to them.
8691 * src/pic16/glue.c (pic16glue): corrected bug with code
8692 initialization which bypassed the variable initializations block.
8694 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8695 COMPILE_FLAGS and added the --nostdinc option
8697 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8699 * device/include/mc68hc908jb8.h: Register defs for another member
8700 of the hc08 family. Contributed by Bjorn Bringert - thanks!
8702 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8704 Documenting changes from previous commits.
8705 * configure.in (version 1.56),
8706 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8707 when generating output files to configure the pic16 library,
8708 but now I've commented it out, since gputils aren't installed in the
8709 SF compile farm, so library won't compile
8711 * device/lib/Makefile.in (version 1.56): initially I've added in
8712 target 'all' the prerequestive 'model-pic16' so it compiled the
8713 pic16 library, but now I've commented it out for the same reasons
8715 * added targets 'model-pic16' and 'objects-pic16' to compile the
8717 * added target 'port-specific-objects-pic16' to handle the
8718 generated libraries and copy them into the build/ directory
8719 * added target 'clean-intermediate-pic16' to clean intermediate
8720 files into pic16 directory
8721 * in target 'installdirs' added line to create directory pic16 in
8722 the installation path
8724 * device/include/Makefile.in (version 1.11): in target 'install'
8725 added lines to copy all header files to installation path,
8726 * in target 'installdirs' added line create directory for pic16
8727 headers in the installation path

8742 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8743 option so that it actually works. Made it specific to the z80, since
8744 the gbz80 doesn't have these kinds of I/O ports.
8746 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8748 * device/include/z180.h,

8761 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8763 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8764 changed interrupt vector table generation to only emit declared vectors.
8765 * device/include/Makefile.in: added missing backslash
8766 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)

8770 Mainly changes to support compilation of the device libraries
8771 * src/pic16/device.c: stack is allocated via symbol and not
8772 via literal number. The symbol is placed in the corresponding
8773 position of the data ram
8774 * (pic16_dump_section): relocatable and absolute uninitialized
8775 data are now emitted in sorted order to reduce section naming,
8776 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8777 weren't marked as being in the access bank,
8779 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8781 Added portion of GNU PIC Library under the directory
8782 device/include/pic16 and device/lib/pic16. These files
8783 contain the declarations of SFRs for the PIC18Fxx2 devices.
8784 The directory is initialized via configure from toplevel.
8786 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8788 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8789 the spilllocations to be compared correctly
8791 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8793 * src/SDCCast.c (decorateType): fixed bug introduced today
8795 2004-01-12 Borut Razem <borut.razem AT siol.net>

8813 * doc/sdccman.lyx: Moved and added some sections, small changes
8814 all over. Telling LaTeX to be less strict with word spacing
8815 to better keep the right margin. Changed some notes about
8816 maintainance of the ports in section 3.2.1 - is it OK like this?
8818 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8820 SDCC source changes:
8821 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8855 UPPER for immediate operands,
8856 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8858 * src/pic16/peeph.def: all peepholes with movff are commented out,
8859 because there is a problem in the pcode peep optimizer,
8860 * src/pic16/ralloc.c: the register allocator can now reuse local
8861 function symbols for another function. This saves register usage.
8862 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8864 Added file src/pic16/NOTES with information about program writing on
8865 the current port version.

8874 * src/SDCCmain.c : fixed #872250: -l command line defined library
8875 files are scanned before standard library files
8877 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8894 gen51Code): more efficient parameter receive for --model-large
8897 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8900 * src/z80/main.c: added missed needLinkerScript flags (more than
8901 one port structure defined in these file)
8902 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8918 needLinkerScript flag
8920 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8921 * src/pic/glue.c: added variable udata_section_name to
8922 override default uninitialized data segment definition for
8923 devices only with SHAREBANK memory (reported from Erik Epetrich)
8924 * (pic14emitOverlay): modified to emit a commented overlay segment
8925 directive when no overlay data exist
8926 * (picglue): modified to emit uninitialized data segment
8927 according to udata_section_name

8933 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8934 object file from '.rel' to '.o' in port->linker structure,

8937 2004-01-07 Borut Razem <borut.razem AT siol.net>
8939 * support/scripts/sdcc.nsi: update PATH
8940 * support/scripts/sdcc.ico: craeted
8942 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
8944 * device/include/Makefile.in: fix install
8945 * doc/Makefile: fix install
8947 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8949 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8951 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8953 include information about variables allocated to the overlay
8956 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8958 * as/mcs51/lkmain.c: Help about -Y option

8970 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8972 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8973 (default behaviour).
8975 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8977 A python script to validate compiler diagnostic messages. It can be
8978 used to verify that sdcc complains about bad c source code and
8979 gives a good location of the error.
8980 * support/valdiag/Makefile,
8981 * support/valdiag/valdiag.py,
8982 * support/valdiag/tests/*
8984 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8997 * src/common.h: added ifndef/define/endif macros
8998 around the header file.
8999 Bug reported from Jesus Calvino-Fraga
9001 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9003 * sdcc.spec: updated
9004 * device/include/Makefile.in: don't install CVS directories
9005 * device/lib/Makefile.in: added removal of CVS directories after install
9006 * doc/Makefile: fixed install, added local_icons
9007 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9008 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9009 * src/ds390/gen.c (genRightShift): fixed bug #870788
9010 * src/SDCCast.c (decorateType): fixed bug #870781
9012 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9014 PIC16 port related changes:
9015 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9016 added variable stackPos,
9018 * gen.c: genCall, assignResultValue: added support for
9019 pushing/retrieving function parameters to/from stack,
9020 genFunction,genEndFunction: setup stack frame for the
9022 genAddrOf: will be changed according to bug 863624
9024 * added files genutils.c and genutils.h which contain gen*
9025 debugged and optimised functions extracted from gen.c
9027 * glue.c: added variable 'externs' which holds extern symbols,
9028 pic16emitRegularMap: is modified to properly handle relocatable
9029 symbols under the new scheme,
9030 pic16createInterruptVect: is modified
9031 pic16printPublics: is modified to emit 'global' assembler directives,
9032 added pic16_printExterns to print extern symbols,
9033 pic16glue: initializes stack/frame pointer in the beginning of
9034 the assembly output. Temporary hack, will be corrected later,
9035 because gplink yet does not support stack and SDCC does not
9036 yet support a type of crt0.o object to create the final binary.
9038 * Removed many lines that contain 8051 legacy code.
9039 * The code is finally placed under a 'code' directive.
9040 * Added port specific options.
9042 * _process_pragma: simplified since now we do not need *special*
9043 include file to define SFR registers. But a separate header
9044 will be needed. This will be developed later.
9045 * _pic16_parseOptions: added, parses port specific options:
9046 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9047 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9048 --preplace-udata-with=
9050 * _pic16_setDefaultOptions: modified to initialize section names,
9051 but hack is temporarly out of order since it needs improvement.
9052 * _pic16_genAssemblerPreamble: configuration words are emitted by
9053 their address instead of their name. This part is incomplete and
9054 supports only the 18Fxx2 devices. Other devices will emit an error
9055 during assembly since they do not contain the same set of config
9057 * _pic16_genIVT: is modified,
9059 * pcode.c: added definitions for some hardware registers that are needed
9061 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9062 All PCI entries are updated. Now LFSR is supported.
9063 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9064 * added pic16_newpCodeOpLit2 to support instructions with
9065 two literal arguments
9066 * pic16_pCode2str: corrected code that emits assembler instructions
9067 with two literal operands and those that have an access bit modifier
9068 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9069 this fixes a bug which caused some labels to be lost, when an
9070 assembler directive was added, i.e. banksel,
9071 * pic16_FixRegisterBanking: improved logic that causes the insertion
9073 * InlineFunction: functions that are called once, are not any more
9074 inlined. This can be a port option in the future,
9076 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9078 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9079 hold the corresponding uninitialized symbols,
9080 * pic16_allocProcessorRegister: registers have explicit marked the
9082 * pic16_allocInternalRegister: registers are explicit marked as
9084 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9085 processing list, so bit registers were lost,
9088 * ralloc.h: added field 'accessBank' and original symbol operand
9089 in register definition,
9090 * removed the field isMapped from register definition,
9092 ** Several functions have been removed from various sources:
9093 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9094 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9095 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9096 pic16_assignRelocatableRegisters
9098 ** others have been introduced:
9099 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9100 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9102 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9104 * support/scripts/inc2h.pl: changed definition of BIT_AT
9105 to emit 'sbit at' instead of 'bit at'. This was a request.
9107 PIC16 port related preliminary changes:
9108 * gen.c: prefixed function popRegFromString with
9109 pic16_ and all references to it corrected
9110 * pcode.c: all pic16_pc_* hardware registers prefixed
9111 with underscore (_),
9112 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9113 * ralloc.c: newReg(): when register is REG_SFR then
9114 set address to rIdx,
9115 pic16_allocProcessorRegister(): marks register wasUsed=0
9116 pic16_writeUsedRegs(): added a call to assign processor
9117 registers via pic16_assignFixedRegisters
9119 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9121 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9122 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9123 variables in unused register banks. Also the SSEG is placed
9124 wherever there is enough space for it, and IDATA can be anywhere
9125 in internal RAM. For now compile using -Wl-Y[stack_size].
9126 The mem file is different for this option as well, since it
9127 makes no sense of talking about DSEG lenght.
9129 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9131 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9132 in certain cases, e.g. when ROM assignment, patch provided
9133 from Albert den Haan.
9135 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10159 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10160 type for bits was changed. It resulted in bit variables becoming
10161 global, which is not permitted in PIC 14 assembly output.
10163 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10165 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10167 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10169 Z80 and MCS51 linkers complaint if a public symbol is defined
10170 in more than one library module:
10174 * as/mcs51/Makefile.in
10176 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10178 A few small changes that speed up the peephole optimizer.
10182 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10184 Try to make the peephole optimizer smarter by maintaining
10185 an association between the assembly source code and the
10186 iCodes that originated them. Put this information to use
10187 with a new peephole rule condition "notVolatile" so that
10188 the rules can be aggressive yet still safe.
10193 * src/mcs51/peeph.def
10195 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10199 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10200 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10201 if the left or right operand symbols have the accuse flag set.
10203 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10205 Changed the type of the result of the ! (NOT) operator to char;
10206 previously it returned the same type as the source. This allows
10207 us to eliminate all the genFloatNot functions (all of its target
10208 implementations were very buggy) since !float can use the same
10211 * src/SDCCicode.c (ast2iCode): ! returns char
10212 * src/mcs51/gen.c (genNot, genNotFloat),
10213 * src/ds390/gen.c (genNot, genNotFloat),
10214 * src/z80/gen.c (genNot, genNotFloat),
10215 * src/pic/gen.c (genNot, genNotFloat),
10216 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10220 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10221 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10222 during interrupts. Ensure WSAVE is located at a shared bank address.
10223 2. Fixed page selection in some places
10224 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10225 the registers name strings.
10226 4. Fixed "signed / unsigned compare" compiler warnings.
10227 5. The PIC port manages its own allocation of the general purpose
10228 registers, but makes no attempt to reuse them. As a result when
10229 compiling it soon runs out of general purpose registers. Some
10230 additional code was added to the files pcode.c and device.c to walk
10231 through the function call tree and rename the registers so that they
10241 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10242 genPlus() & genMinus() when the result is the same as left or right
10244 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10246 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
10248 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10250 Made bitfield a distinct type from bit so that bitfields
10251 convert as per ANSI C and bits retain their traditional
10252 boolean style behaviour. Implemented bitfield support in
10260 * src/ds390/gen.c: bit v bitfield split
10261 * src/z80/gen.c: New support for bitfields
10262 * support/regression/tests/bitfields.c: reenabled z80,
10265 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10267 Rules 246.x, 247.x relate to bitfields, the others speed up
10268 access to xdata mapped I/O devices.
10270 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10272 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10274 Cleaned up genPackBits and genUnpackBits and added two helper
10275 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10276 for literal assignments in genPackBits (thanks to Frieder for
10282 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10284 Fixed bug #748310 (pointer to function type mishandled when the
10285 function name is omitted). Also fixed a SIGSEGV when a function
10286 attribute (reentrant, etc) is used on a non-function or on a
10287 function but misplaced before the parameter list.
10289 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10291 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10292 * support/Util/SDCCerr.h,
10293 * support/Util/SDCCerr.c: Added func attr misuse error msg
10295 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10297 Fixed bug #787649 by anonymous
10298 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10299 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10301 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10303 Fixed numerous bitfield problems.
10305 * src/SDCC.y: More bitfield related error checking
10307 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
10308 * support/Util/SDCCerr.h,
10309 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
10310 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs

10312 * support/regression/tests/bitfields.c: tests added
10314 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10316 Made the constant following the "interrupt" keyword optional. If
10317 omitted, the function will not automatically be given an entry
10318 in the interrupt vector table (similar to #pragma NOIV, but
10319 less syntacticly kludgy). The interrupt number is also now
10320 range checked. Also fixed a bug in the high order bit example
10327 * support/Util/SDCCerr.c
10328 * support/Util/SDCCerr.h
10331 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10334 * src/SDCCicode.c (operandOperation): rewritten some ops
10335 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10336 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10338 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10339 be re-activated by defining REDUCE_LITERALS)
10340 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10341 unsigned, but are signed by default
10342 * src/SDCCval.c (constVal): rearranged
10343 * src/SDCCval.c (valMod): preliminary fix
10344 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10384 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10385 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10386 constants are unsigned; added recognition of "u" flag for unsigned
10387 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10388 * src/SDCCval.c (valDiv, valMod): fixed signdness

10796 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10797 the regression tests I'm not brave enough to enable 245.b, 245.c
10798 * doc/sdccman.lyx: added latex preamble for hyperref package.
10799 Using pdflatex this will give you a hyperlinked pdf file with
10800 bookmarks. (prepend '%' before /usepackage if this breaks something)

10850 added if/endif conditional macros to remove options help
10851 messages from optionsTable when a port is not configured, added
10852 support for the PIc16 port in the ports table, when executing
10853 the compiler with no port specified on command line, a default
10854 port is selected with the new macro DEFAULT_PORT which is
10855 defined in port.h, in setDefaultOptions() linkOptions is removed
10856 from initialization assignment, since now it is a set,
10857 parseCmdLine uses setParseWithComma for linkOptions, in
10858 linkEdit() linkOptions are accessed with new function indexSet()
10859 which returns the i'th item of a set variable. See SDCCset.c, in
10860 linkEdit() when calling buildCmdLine(), added linkOptions as
10861 last argument. Now users can pass arguments to gplink via the
10862 -Wl option, main() uses pic16glue() to glue up pic16 programs

10874 * src/pic16/glue.c: commented out some error producing lines
10875 * src/pic16/main.c: __config directives are commented out to stop
10876 gpasm complaining and test the linkage with gplink, _linkCmd and
10877 _asmCmd changed to be more gplink and gpasm friendly
10878 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10879 produced an error when parsed, peep rule 12 is added to utilize
10880 movff, but it is commented out since the pCode does not support
10881 yet a command with 2 address arguments
10883 2003-05-18 <johan AT balder>
10885 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11992 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11993 area BSEG. Also moves, if possible, the DATA area down into the internal
11994 ram so more space is available.
11996 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11999 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12000 not bytes. Function summary() which creates a memory usage summary
12001 file with extension .mem. Reports of overlaping stack and small stack
12002 size. If the space for the stack is less than 16 bytes aslink trows a
12005 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12006 the 8051. Option 'y' for memory summary output file.
12008 Changes to sdcc (All the changes are marked with 'JCF'):
12010 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12012 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12013 overlaying area for it (uses RegBankUsed[4]).
12015 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12016 bank zero as used by default. By default aslink locates the stack
12017 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12018 the creation of the .mem file. Delegates the allocation of data area
12019 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12020 the begining of the stack area to aslink.
12022 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12023 glue() in SDCCglue.c creates an area for it.
12025 2002-09-03 Borut Razem <borut.razem AT siol.net>
12026 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12027 sdcc/src/pic/glue.c:
12028 introduced atexit() handler for teporay files removal in case of
12029 errors, assertions, ...
12031 2002-08-29 Borut Razem <borut.razem AT siol.net>
12032 * sdcc/support/cpp2/auto-host_vc_in.h:
12033 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12034 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12035 Maybe there is a similar problem with BORLANDC? It should be checked!
12037 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12038 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12039 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12040 was not executed, and the compiler (cl) launched a warning:
12041 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12043 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12044 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12046 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12047 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12049 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12050 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12051 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12052 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12053 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12054 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12055 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12056 - added Release configuration in VS projects
12057 - review of compiler an linker options
12058 - VC .exe files are generated in bin_vc directory, not to interfere
12059 with binaries generated from other projects (cygwin, mingw, bcc ...)
12061 * sdcc/src/yacc.dsp: added
12063 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12064 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12065 and insert the version number definitions from .version
12067 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12069 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12070 added - genarate auto-host.h using auto-host_vc_in.h as template
12073 removed from CVS, generated automatically
12075 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12076 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12078 2002-08-11 Borut Razem <borut.razem AT siol.net>
12079 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12081 2002-08-10 Borut Razem <borut.razem AT siol.net>
12082 * src/SDCCmain.c (main):
12083 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12084 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12085 The consequence was that some temporary files were not removed.
12088 unification of code in functions tempfilename() and tempfile():
12089 function tempnam() is defined in Visual Studio 6.0 and .NET
12091 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12093 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12094 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12095 - removed compiler command line option /WX: Treats all warnings as errors
12096 - update a list of source files, included into the project
12098 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12099 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12100 changed project type to Generic Project so that can be correcly converted to VS.NET project
12102 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12104 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12106 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12108 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12109 added return 0 statements after assert() to make compiler happy
12111 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12112 added newline in the def file to keep MSC compiler satisfied
12114 * sdcc/src/z80/gen.c:
12115 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12116 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12117 - solved MSC error in function aopDump()
12119 * sdcc_vc.h: define PREFIX as "\\sdcc"
12121 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12294 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12296 * sdcc/src/SDCCloop.c:
12297 Previous fix was not good. basic blocks that have "break" or "return" are
12298 not really partof a loop , but live ranges used in these blocks should
12299 be live thru the entire loop, so set partOfLoop but don't add them to
12302 2002-02-21 <johan AT FRIJA>
12304 * src/SDCCcse.c: fixed bug #514308
12306 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
