1749 on rIfx (genCmp was broken)
1751 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1753 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1754 * src/z80/main.c (_keywords[]),
1755 * src/SDCCglobal.h (struct options),
1757 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1758 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1759 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1760 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1761 always available in leading double underscore form. The C99 support is
1762 mostly missing, but it's a start.
1763 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1764 reserved identifier "__data".
1766 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1768 * src/mcs51/peeph.def: fixed bug 1170013

1812 2005-03-20 Borut Razem <borut.razem AT siol.net>
1814 * support/scripts/inc2h.pl: WIN32 port

1842 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1844 * device/lib/printf_large.c: removed inline assembly for portability and
1845 readability. Use printf_fast if speed or size are more important.
1846 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1847 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1849 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1851 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1852 prevent compiler warning
1854 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1856 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1857 moved to level 0 and declared as static. Also they are explicit
1858 placed in access bank. This was necessery because some times they
1859 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1860 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1861 optimizations. Currently only compare to unsigned char is implemented,
1862 * src/pic16/gen.c: added fReturnIdx array,
1863 * (struct resolvedIfx) is moved to gen.h and made public,
1864 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1865 * (aopForSym): added an optimization to directly store in stack of
1866 the operand of a SEND iCode,
1867 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1868 but as registers instead (AOP_REG) using the fReturnIdx array,
1869 * (pic16_freeAsmop): remove the freed register from the
1870 _G.sregsAlloc field,
1871 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1872 a compare of 'WREG',
1873 * (pic16_popGetTempRegCond): changed function prototype, now
1874 function takes also a bitVector argument v which holds the current
1875 set of registers that are allocated for stack access by aopForSym,
1876 registers allocated in aopForSym for accessing stack symbols are not
1877 any more part of the functions usedRegs field,
1878 * (genCall): some times aopOp is called for a stack variable to be
1879 send, aopForSym might perform the push, if this is true make sure
1880 that genCall doesn't push the variable twice by testing _G.resDirect,
1881 * (genFunction): changed testing for unspecified interrupt number
1882 from 256 to INTNO_UNSPEC,
1883 * modified selection scheme of frame pointer generation. Previously
1884 if function did use local registers a frame pointer was generated,
1885 now a frame pointer is generated only if function has arguments
1886 (that need PLUSW2 register access), or has stack arguments, or the
1887 compiler is not instructed to omit the frame pointer,
1888 * (genEndFunction): before restoring local registers that were saved
1889 in the function preamble, also restore the registers that *might*
1890 have been allocated for stack access,
1891 * (genRet): removed some old comments,
1892 * (genCmp, the active (RN's) version): added a call to the
1893 pic16_genCmp_special function to perform the compare with a more
1894 robust and optimized way,
1895 * (genInline): a feature has been added in inline code generation,
1896 which allows a wildcard variable substitution when writing inline
1897 assembly. Code is incomplete and experimental therefore undocumented,
1898 * (genCast): changed order of aopOp for result and right to allow
1899 aopForSym to directly load the result if possible,
1900 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1901 perform an optimized compare on some selected special occasions,
1902 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1903 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1904 generate an IVT any more,
1905 * src/pic16/main.c (pic16_optionsTable): added command line option
1907 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1908 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1910 * src/pic16/NOTES: Raphael Neider added in list of active developers
1911 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1912 jumptable_end to prevent bug #,
1913 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1914 inCond and outCond fields,
1915 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1916 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1917 turn off register spilling,
1918 * (packRegsForOneUse): synced with other ports' versions although it
1919 is not used currently,
1920 * (pic16_packRegisters): added an optimization while reading
1921 structure bitfields, some registers may be saved (malloc code is
1922 decreased by 80 bytes)
1924 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1926 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1927 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1928 this can be optimized more?
1930 2005-03-10 Raphael Neider <rneider AT web.de>
1932 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1933 genNearPointerGet): (hopefully) fixed access to bitfields via
1934 pointers (p->bitN = x; and x = p->bitN; failed)
1936 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2113 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2114 (sizeof(sectNames) changed to sizeof(sectName))

2122 of (byte sized) temporaries (assign them to WREG for now)
2123 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2124 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2125 this might fix SIGSEGVs on MinGW...
2126 * src/SDCCopt.c (killDeadCode): restored original behaviour
2127 (volatile operands might get thrown away though)
2129 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2585 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
2587 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
2590 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
2592 * src/pic16/device.h,
2593 * src/pic16/genarith.c,
2596 * src/pic16/pcode.c: applied patches #1068154 and #1070213
2598 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2600 Large cummulative patch for pic16 port.
2601 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2602 to call when a stack overflow occurs,
2603 * (malloc.h): added CVS Id tag,
2604 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2606 * added libc directory. The current version of LibC contains string
2607 functions, ctype functions and macros and some functions of the
2608 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2609 be extensively tested in the future. Standard disclaimer here.
2610 Library is not automatically build yet. But one can build it by
2611 invoking 'make' inside the libc directory.
2612 * added ADC library under libio. Preliminary version yet.
2614 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2615 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2616 aopForRemat() now and not by pic16_aopOp(),
2617 * (pic16_popGetTempReg): removed warning messgae when allocating
2618 temporary registers, its a buggy feature and will be removed,
2619 * (pic16_popGet): set register instance field in AOP_CRY,
2620 * (pic16_outBitC): fixed for results in size greater than 1,
2621 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2622 * (pic16_storeForReturn): optimized return of 0,
2623 * (genCmp): experimental code for new genCmp which uses PIC18's
2624 special compare&skip instructions. Initial tests fail some times
2625 with variables grater than 1 byte in size, so new code is disabled,
2626 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2628 * (genCast): began a fix to optimize the casting of a bit to another
2629 bit, now assigning a bitfield to another bitfield will fail, sorry,
2630 * src/pic16/main.c: disabled the use of lr-support feature,
2631 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2632 * added some function prototypes, added function _debugf prototype,
2633 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2634 bits with offset (case PO_GPR_BIT),
2635 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2637 * (isBankInstruction): modified to return 0 for no banking instruction,
2638 and 1 for banking instruction,
2639 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2640 caused stop processing pCodes after a inline assembly block,
2641 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2642 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2643 registers when it shouldn't,
2644 * src/pic16/ralloc.c (allocReg): add preliminary support for
2645 supporting a limited set of temporary registers,
2647 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2649 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2650 genDataPointerSet): ensure assignments always copy in MSB to LSB
2652 (loadRegFromAop): recognize CLRH optimization,
2653 (genFunction): optimize RECEIVE iCodes in reentrant functions
2655 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2657 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2658 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2660 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2667 * device/lib/_gptrgetc.c (_gptrgetc),
2668 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2669 instead of sjmp to ret
2670 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2671 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

5652 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5654 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5655 loaded with the linker search paths (-L arguments) and the libraries
5656 to be linked with the current source (-l arguments). Changes
5657 currently will affect only the pic16 port.
5658 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5659 include path the port specific paths and port specific libraries,
5660 * gplink command now contains the $3 argument,
5661 * src/pic16/device.h,
5662 * src/pic16/device.c,: structure PIC_device is made public and
5663 renamed to PIC16_device, the same for variable Pics which is renamed

5678 Documenting changes from previous commits.
5679 * configure.in (version 1.56),
5680 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5681 when generating output files to configure the pic16 library,
5682 but now I've commented it out, since gputils aren't installed in the
5683 SF compile farm, so library won't compile
5685 * device/lib/Makefile.in (version 1.56): initially I've added in
5686 target 'all' the prerequestive 'model-pic16' so it compiled the
5687 pic16 library, but now I've commented it out for the same reasons
5689 * added targets 'model-pic16' and 'objects-pic16' to compile the
5691 * added target 'port-specific-objects-pic16' to handle the
5692 generated libraries and copy them into the build/ directory
5693 * added target 'clean-intermediate-pic16' to clean intermediate
5694 files into pic16 directory
5695 * in target 'installdirs' added line to create directory pic16 in

5716 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5717 option so that it actually works. Made it specific to the z80, since
5718 the gbz80 doesn't have these kinds of I/O ports.
5720 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5722 * device/include/z180.h,

5746 via literal number. The symbol is placed in the corresponding
5747 position of the data ram
5748 * (pic16_dump_section): relocatable and absolute uninitialized
5749 data are now emitted in sorted order to reduce section naming,
5750 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5751 weren't marked as being in the access bank,
5753 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5755 Added portion of GNU PIC Library under the directory
5756 device/include/pic16 and device/lib/pic16. These files
5757 contain the declarations of SFRs for the PIC18Fxx2 devices.
5758 The directory is initialized via configure from toplevel.
5760 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5762 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5788 all over. Telling LaTeX to be less strict with word spacing
5789 to better keep the right margin. Changed some notes about
5790 maintainance of the ports in section 3.2.1 - is it OK like this?
5792 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5830 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5832 * src/pic16/peeph.def: all peepholes with movff are commented out,
5833 because there is a problem in the pcode peep optimizer,
5834 * src/pic16/ralloc.c: the register allocator can now reuse local

5836 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5838 Added file src/pic16/NOTES with information about program writing on
5839 the current port version.

5871 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5874 * src/z80/main.c: added missed needLinkerScript flags (more than
5875 one port structure defined in these file)
5876 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

5894 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5895 * src/pic/glue.c: added variable udata_section_name to
5896 override default uninitialized data segment definition for
5897 devices only with SHAREBANK memory (reported from Erik Epetrich)
5898 * (pic14emitOverlay): modified to emit a commented overlay segment
5899 directive when no overlay data exist
5900 * (picglue): modified to emit uninitialized data segment
5901 according to udata_section_name

5927 include information about variables allocated to the overlay
5930 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5932 * as/mcs51/lkmain.c: Help about -Y option

5944 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5946 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5947 (default behaviour).
5949 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5951 A python script to validate compiler diagnostic messages. It can be
5952 used to verify that sdcc complains about bad c source code and
5953 gives a good location of the error.
5954 * support/valdiag/Makefile,
5955 * support/valdiag/valdiag.py,
5956 * support/valdiag/tests/*
5958 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5960 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5971 * src/common.h: added ifndef/define/endif macros
5972 around the header file.
5973 Bug reported from Jesus Calvino-Fraga
5975 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5977 * sdcc.spec: updated
5978 * device/include/Makefile.in: don't install CVS directories
5979 * device/lib/Makefile.in: added removal of CVS directories after install
5980 * doc/Makefile: fixed install, added local_icons
5981 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5982 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5983 * src/ds390/gen.c (genRightShift): fixed bug #870788
5984 * src/SDCCast.c (decorateType): fixed bug #870781
5986 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5988 PIC16 port related changes:
5989 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5990 added variable stackPos,
5992 * gen.c: genCall, assignResultValue: added support for
5993 pushing/retrieving function parameters to/from stack,
5994 genFunction,genEndFunction: setup stack frame for the
5996 genAddrOf: will be changed according to bug 863624
5998 * added files genutils.c and genutils.h which contain gen*
5999 debugged and optimised functions extracted from gen.c
6001 * glue.c: added variable 'externs' which holds extern symbols,
6002 pic16emitRegularMap: is modified to properly handle relocatable
6003 symbols under the new scheme,
6004 pic16createInterruptVect: is modified
6005 pic16printPublics: is modified to emit 'global' assembler directives,
6006 added pic16_printExterns to print extern symbols,
6007 pic16glue: initializes stack/frame pointer in the beginning of
6008 the assembly output. Temporary hack, will be corrected later,
6009 because gplink yet does not support stack and SDCC does not
6010 yet support a type of crt0.o object to create the final binary.
6012 * Removed many lines that contain 8051 legacy code.
6013 * The code is finally placed under a 'code' directive.
6014 * Added port specific options.
6016 * _process_pragma: simplified since now we do not need *special*
6017 include file to define SFR registers. But a separate header
6018 will be needed. This will be developed later.
6019 * _pic16_parseOptions: added, parses port specific options:
6020 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6021 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6022 --preplace-udata-with=
6024 * _pic16_setDefaultOptions: modified to initialize section names,
6025 but hack is temporarly out of order since it needs improvement.
6026 * _pic16_genAssemblerPreamble: configuration words are emitted by
6027 their address instead of their name. This part is incomplete and
6028 supports only the 18Fxx2 devices. Other devices will emit an error
6029 during assembly since they do not contain the same set of config
6031 * _pic16_genIVT: is modified,
6033 * pcode.c: added definitions for some hardware registers that are needed
6035 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6036 All PCI entries are updated. Now LFSR is supported.
6037 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6038 * added pic16_newpCodeOpLit2 to support instructions with
6039 two literal arguments
6040 * pic16_pCode2str: corrected code that emits assembler instructions
6041 with two literal operands and those that have an access bit modifier
6042 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6043 this fixes a bug which caused some labels to be lost, when an
6044 assembler directive was added, i.e. banksel,
6045 * pic16_FixRegisterBanking: improved logic that causes the insertion
6047 * InlineFunction: functions that are called once, are not any more
6048 inlined. This can be a port option in the future,
6050 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6052 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6053 hold the corresponding uninitialized symbols,
6054 * pic16_allocProcessorRegister: registers have explicit marked the
6056 * pic16_allocInternalRegister: registers are explicit marked as
6058 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6059 processing list, so bit registers were lost,
6062 * ralloc.h: added field 'accessBank' and original symbol operand
6063 in register definition,
6064 * removed the field isMapped from register definition,
6066 ** Several functions have been removed from various sources:
6067 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6068 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6069 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6070 pic16_assignRelocatableRegisters
6072 ** others have been introduced:
6073 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6074 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6076 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6078 * support/scripts/inc2h.pl: changed definition of BIT_AT
6079 to emit 'sbit at' instead of 'bit at'. This was a request.
6081 PIC16 port related preliminary changes:
6082 * gen.c: prefixed function popRegFromString with
6083 pic16_ and all references to it corrected
6084 * pcode.c: all pic16_pc_* hardware registers prefixed
6085 with underscore (_),
6086 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6087 * ralloc.c: newReg(): when register is REG_SFR then
6088 set address to rIdx,
6089 pic16_allocProcessorRegister(): marks register wasUsed=0
6090 pic16_writeUsedRegs(): added a call to assign processor
6091 registers via pic16_assignFixedRegisters
6093 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6095 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6096 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6097 variables in unused register banks. Also the SSEG is placed
6098 wherever there is enough space for it, and IDATA can be anywhere
6099 in internal RAM. For now compile using -Wl-Y[stack_size].
6100 The mem file is different for this option as well, since it
6101 makes no sense of talking about DSEG lenght.
6103 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6105 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6106 in certain cases, e.g. when ROM assignment, patch provided
6107 from Albert den Haan.
6109 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6654 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6656 Fixed a number of problems revealed by bug #827883.
6657 * src/SDCCloop.c (loopInvariants): Spill location of the
6658 result operand should be recomputed if extracted from
6659 a loop. Also, don't extract assignments of an iTemp

6662 not occur if the control variable is involved with a
6663 relational operator.

7152 A few small changes that speed up the peephole optimizer.
7156 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7158 Try to make the peephole optimizer smarter by maintaining
7159 an association between the assembly source code and the
7160 iCodes that originated them. Put this information to use
7161 with a new peephole rule condition "notVolatile" so that
7162 the rules can be aggressive yet still safe.

7179 Changed the type of the result of the ! (NOT) operator to char;
7180 previously it returned the same type as the source. This allows
7181 us to eliminate all the genFloatNot functions (all of its target
7182 implementations were very buggy) since !float can use the same

7194 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7195 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7196 during interrupts. Ensure WSAVE is located at a shared bank address.
7197 2. Fixed page selection in some places
7198 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7199 the registers name strings.
7200 4. Fixed "signed / unsigned compare" compiler warnings.
7201 5. The PIC port manages its own allocation of the general purpose
7202 registers, but makes no attempt to reuse them. As a result when
7203 compiling it soon runs out of general purpose registers. Some
7204 additional code was added to the files pcode.c and device.c to walk
7205 through the function call tree and rename the registers so that they
7215 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7222 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7224 Made bitfield a distinct type from bit so that bitfields
7225 convert as per ANSI C and bits retain their traditional
7226 boolean style behaviour. Implemented bitfield support in
7234 * src/ds390/gen.c: bit v bitfield split
7235 * src/z80/gen.c: New support for bitfields

7239 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7241 Rules 246.x, 247.x relate to bitfields, the others speed up
7242 access to xdata mapped I/O devices.
7244 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7246 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7248 Cleaned up genPackBits and genUnpackBits and added two helper
7249 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7250 for literal assignments in genPackBits (thanks to Frieder for
7256 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7258 Fixed bug #748310 (pointer to function type mishandled when the
7259 function name is omitted). Also fixed a SIGSEGV when a function
7260 attribute (reentrant, etc) is used on a non-function or on a
7261 function but misplaced before the parameter list.

7290 Made the constant following the "interrupt" keyword optional. If
7291 omitted, the function will not automatically be given an entry
7292 in the interrupt vector table (similar to #pragma NOIV, but
7293 less syntacticly kludgy). The interrupt number is also now
7294 range checked. Also fixed a bug in the high order bit example

7770 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7771 the regression tests I'm not brave enough to enable 245.b, 245.c
7772 * doc/sdccman.lyx: added latex preamble for hyperref package.
7773 Using pdflatex this will give you a hyperlinked pdf file with

7788 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
7790 Applied patch from bug 737905 (renamed yylineo to mylineno):
7797 * src/pic16/pcode.c: Cleaned warnings
7798 * src/pic16/pcodeflow.c: Cleaned warnings
7799 * src/pic16/pcoderegs.c: Cleaned warnings

7812 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7814 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7815 it can be defined with CFLAGS when running configure
7816 * src/SDCCmain.c: fixed compiling + linking with object files
7818 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7820 * configure.in: configure for pic16 port,
7821 added --disable-pic16-port
7822 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7823 * src/SDCCmain.c: linkOptions is changed to set *,
7824 added if/endif conditional macros to remove options help
7825 messages from optionsTable when a port is not configured, added
7826 support for the PIc16 port in the ports table, when executing
7827 the compiler with no port specified on command line, a default
7828 port is selected with the new macro DEFAULT_PORT which is
7829 defined in port.h, in setDefaultOptions() linkOptions is removed
7830 from initialization assignment, since now it is a set,
7831 parseCmdLine uses setParseWithComma for linkOptions, in
7832 linkEdit() linkOptions are accessed with new function indexSet()
7833 which returns the i'th item of a set variable. See SDCCset.c, in
7834 linkEdit() when calling buildCmdLine(), added linkOptions as
7835 last argument. Now users can pass arguments to gplink via the
7836 -Wl option, main() uses pic16glue() to glue up pic16 programs
7837 * src/SDCCpeeph.c: various changes to support pic16

7848 * src/pic16/glue.c: commented out some error producing lines
7849 * src/pic16/main.c: __config directives are commented out to stop
7850 gpasm complaining and test the linkage with gplink, _linkCmd and
7851 _asmCmd changed to be more gplink and gpasm friendly
7852 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7853 produced an error when parsed, peep rule 12 is added to utilize
7854 movff, but it is commented out since the pCode does not support
7855 yet a command with 2 address arguments
7857 2003-05-18 <johan AT balder>
7859 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7884 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7886 2003-05-11 Borut Razem <borut.razem AT siol.net>
7888 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7889 the path of bin directory, so that PATH is the only env. variable, which has to be set
7890 in case of standard installation.
7891 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8894 * src/SDCCicode.c: fixed array add
8896 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8897 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8898 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8900 2003-01-04 <johan AT balder>
8902 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8904 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8905 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8917 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8918 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8920 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8922 * in \sdcc\as\mcs51\ changed these files in order to create an
8923 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8924 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8925 following files to include the previous two files: aslink.dsp,
8926 Makefile.aslink, Makefile.bcc, and Makefile.in.
8928 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8929 .adb instead of .cdb
8931 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8933 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8934 value from option --iram-size.
8936 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8938 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8941 2002-09-18 <wiml AT hhhh.org>
8943 * SDCClrange.h: exposed setFromRange() and setToRange()
8944 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8945 packRegsForAccUse() (bug 542397)
8946 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8947 multiple times and emitting the fetch operations more than once
8948 added aopGetUsesAcc() function to allow binary operators to
8949 fetch their operands in the correct order; made genMinus() emit
8950 compact code for X = LITERAL - Y
8952 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8953 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8954 sprintf() in line 1267.
8956 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8957 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8960 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8961 Changes to aslink (All the changes are marked with 'JCF'):
8963 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8966 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8967 area BSEG. Also moves, if possible, the DATA area down into the internal
8968 ram so more space is available.
8970 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8973 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8974 not bytes. Function summary() which creates a memory usage summary
8975 file with extension .mem. Reports of overlaping stack and small stack
8976 size. If the space for the stack is less than 16 bytes aslink trows a
8979 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8980 the 8051. Option 'y' for memory summary output file.
8982 Changes to sdcc (All the changes are marked with 'JCF'):
8984 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8986 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8987 overlaying area for it (uses RegBankUsed[4]).
8989 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8990 bank zero as used by default. By default aslink locates the stack
8991 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8992 the creation of the .mem file. Delegates the allocation of data area
8993 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8994 the begining of the stack area to aslink.
8996 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8997 glue() in SDCCglue.c creates an area for it.
8999 2002-09-03 Borut Razem <borut.razem AT siol.net>
9000 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9001 sdcc/src/pic/glue.c:
9002 introduced atexit() handler for teporay files removal in case of
9003 errors, assertions, ...
9005 2002-08-29 Borut Razem <borut.razem AT siol.net>
9006 * sdcc/support/cpp2/auto-host_vc_in.h:
9007 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9008 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9009 Maybe there is a similar problem with BORLANDC? It should be checked!
9011 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9012 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9013 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9014 was not executed, and the compiler (cl) launched a warning:
9015 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9017 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9018 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9020 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9021 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9023 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9024 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9027 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9028 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9029 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9030 - added Release configuration in VS projects
9031 - review of compiler an linker options
9032 - VC .exe files are generated in bin_vc directory, not to interfere
9033 with binaries generated from other projects (cygwin, mingw, bcc ...)
9035 * sdcc/src/yacc.dsp: added
9037 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9038 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9039 and insert the version number definitions from .version
9041 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9043 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9044 added - genarate auto-host.h using auto-host_vc_in.h as template
9047 removed from CVS, generated automatically
9049 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9050 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9052 2002-08-11 Borut Razem <borut.razem AT siol.net>
9053 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9055 2002-08-10 Borut Razem <borut.razem AT siol.net>
9056 * src/SDCCmain.c (main):
9057 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9058 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9059 The consequence was that some temporary files were not removed.
9062 unification of code in functions tempfilename() and tempfile():
9063 function tempnam() is defined in Visual Studio 6.0 and .NET
9065 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9067 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9068 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9069 - removed compiler command line option /WX: Treats all warnings as errors
9070 - update a list of source files, included into the project
9072 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9073 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
