1742 * (genCmp): adapted to new genSkipc semantics
1743 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
1744 on rIfx (genCmp was broken)
1746 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1748 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1749 * src/z80/main.c (_keywords[]),
1750 * src/SDCCglobal.h (struct options),
1752 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1753 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1754 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1755 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1756 always available in leading double underscore form. The C99 support is
1757 mostly missing, but it's a start.
1758 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1759 reserved identifier "__data".
1761 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1763 * src/mcs51/peeph.def: fixed bug 1170013

1774 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1776 * src/port.h (struct PORT),

1805 immedDom() returning wrong block; probably fixes bug #1160833)
1807 2005-03-20 Borut Razem <borut.razem AT siol.net>
1809 * support/scripts/inc2h.pl: WIN32 port

1813 * device/lib/makefile.in: added abs.c and labs.c
1815 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1817 * device/include/stdint.h: added
1818 * device/lib/abs.c: added

1837 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1839 * device/lib/printf_large.c: removed inline assembly for portability and
1840 readability. Use printf_fast if speed or size are more important.
1841 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1842 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1844 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1846 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1847 prevent compiler warning
1849 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1851 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1852 moved to level 0 and declared as static. Also they are explicit
1853 placed in access bank. This was necessery because some times they
1854 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1855 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1856 optimizations. Currently only compare to unsigned char is implemented,
1857 * src/pic16/gen.c: added fReturnIdx array,
1858 * (struct resolvedIfx) is moved to gen.h and made public,
1859 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1860 * (aopForSym): added an optimization to directly store in stack of
1861 the operand of a SEND iCode,
1862 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1863 but as registers instead (AOP_REG) using the fReturnIdx array,
1864 * (pic16_freeAsmop): remove the freed register from the
1865 _G.sregsAlloc field,
1866 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1867 a compare of 'WREG',
1868 * (pic16_popGetTempRegCond): changed function prototype, now
1869 function takes also a bitVector argument v which holds the current
1870 set of registers that are allocated for stack access by aopForSym,
1871 registers allocated in aopForSym for accessing stack symbols are not
1872 any more part of the functions usedRegs field,
1873 * (genCall): some times aopOp is called for a stack variable to be
1874 send, aopForSym might perform the push, if this is true make sure
1875 that genCall doesn't push the variable twice by testing _G.resDirect,
1876 * (genFunction): changed testing for unspecified interrupt number
1877 from 256 to INTNO_UNSPEC,
1878 * modified selection scheme of frame pointer generation. Previously
1879 if function did use local registers a frame pointer was generated,
1880 now a frame pointer is generated only if function has arguments
1881 (that need PLUSW2 register access), or has stack arguments, or the
1882 compiler is not instructed to omit the frame pointer,
1883 * (genEndFunction): before restoring local registers that were saved
1884 in the function preamble, also restore the registers that *might*
1885 have been allocated for stack access,
1886 * (genRet): removed some old comments,
1887 * (genCmp, the active (RN's) version): added a call to the
1888 pic16_genCmp_special function to perform the compare with a more
1889 robust and optimized way,
1890 * (genInline): a feature has been added in inline code generation,
1891 which allows a wildcard variable substitution when writing inline
1892 assembly. Code is incomplete and experimental therefore undocumented,
1893 * (genCast): changed order of aopOp for result and right to allow
1894 aopForSym to directly load the result if possible,
1895 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1896 perform an optimized compare on some selected special occasions,
1897 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1898 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1899 generate an IVT any more,
1900 * src/pic16/main.c (pic16_optionsTable): added command line option
1902 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1903 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1905 * src/pic16/NOTES: Raphael Neider added in list of active developers
1906 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1907 jumptable_end to prevent bug #,
1908 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1909 inCond and outCond fields,
1910 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1911 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1912 turn off register spilling,
1913 * (packRegsForOneUse): synced with other ports' versions although it
1914 is not used currently,
1915 * (pic16_packRegisters): added an optimization while reading
1916 structure bitfields, some registers may be saved (malloc code is
1917 decreased by 80 bytes)
1919 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1921 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1922 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1923 this can be optimized more?
1925 2005-03-10 Raphael Neider <rneider AT web.de>
1927 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1928 genNearPointerGet): (hopefully) fixed access to bitfields via
1929 pointers (p->bitN = x; and x = p->bitN; failed)
1931 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2118 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2119 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2120 this might fix SIGSEGVs on MinGW...
2121 * src/SDCCopt.c (killDeadCode): restored original behaviour
2122 (volatile operands might get thrown away though)
2124 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2593 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2595 Large cummulative patch for pic16 port.
2596 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2597 to call when a stack overflow occurs,
2598 * (malloc.h): added CVS Id tag,
2599 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2601 * added libc directory. The current version of LibC contains string
2602 functions, ctype functions and macros and some functions of the
2603 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2604 be extensively tested in the future. Standard disclaimer here.
2605 Library is not automatically build yet. But one can build it by
2606 invoking 'make' inside the libc directory.
2607 * added ADC library under libio. Preliminary version yet.
2609 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2610 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2611 aopForRemat() now and not by pic16_aopOp(),
2612 * (pic16_popGetTempReg): removed warning messgae when allocating
2613 temporary registers, its a buggy feature and will be removed,
2614 * (pic16_popGet): set register instance field in AOP_CRY,
2615 * (pic16_outBitC): fixed for results in size greater than 1,
2616 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2617 * (pic16_storeForReturn): optimized return of 0,
2618 * (genCmp): experimental code for new genCmp which uses PIC18's
2619 special compare&skip instructions. Initial tests fail some times
2620 with variables grater than 1 byte in size, so new code is disabled,
2621 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2623 * (genCast): began a fix to optimize the casting of a bit to another
2624 bit, now assigning a bitfield to another bitfield will fail, sorry,
2625 * src/pic16/main.c: disabled the use of lr-support feature,
2626 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2627 * added some function prototypes, added function _debugf prototype,
2628 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2629 bits with offset (case PO_GPR_BIT),
2630 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2632 * (isBankInstruction): modified to return 0 for no banking instruction,
2633 and 1 for banking instruction,
2634 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2635 caused stop processing pCodes after a inline assembly block,
2636 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2637 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2638 registers when it shouldn't,
2639 * src/pic16/ralloc.c (allocReg): add preliminary support for
2640 supporting a limited set of temporary registers,
2642 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2644 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2645 genDataPointerSet): ensure assignments always copy in MSB to LSB
2647 (loadRegFromAop): recognize CLRH optimization,
2648 (genFunction): optimize RECEIVE iCodes in reentrant functions
2650 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2652 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2653 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2655 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
2656 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
2657 contiguous with data

2661 * device/lib/_gptrget.c (_gptrget),
2662 * device/lib/_gptrgetc.c (_gptrgetc),
2663 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2664 instead of sjmp to ret
2665 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2666 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2668 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5647 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5649 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5650 loaded with the linker search paths (-L arguments) and the libraries
5651 to be linked with the current source (-l arguments). Changes
5652 currently will affect only the pic16 port.
5653 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5654 include path the port specific paths and port specific libraries,
5655 * gplink command now contains the $3 argument,
5656 * src/pic16/device.h,
5657 * src/pic16/device.c,: structure PIC_device is made public and
5658 renamed to PIC16_device, the same for variable Pics which is renamed

5673 Documenting changes from previous commits.
5674 * configure.in (version 1.56),
5675 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5676 when generating output files to configure the pic16 library,
5677 but now I've commented it out, since gputils aren't installed in the
5678 SF compile farm, so library won't compile
5680 * device/lib/Makefile.in (version 1.56): initially I've added in
5681 target 'all' the prerequestive 'model-pic16' so it compiled the
5682 pic16 library, but now I've commented it out for the same reasons
5684 * added targets 'model-pic16' and 'objects-pic16' to compile the
5686 * added target 'port-specific-objects-pic16' to handle the
5687 generated libraries and copy them into the build/ directory
5688 * added target 'clean-intermediate-pic16' to clean intermediate
5689 files into pic16 directory
5690 * in target 'installdirs' added line to create directory pic16 in

5741 via literal number. The symbol is placed in the corresponding
5742 position of the data ram
5743 * (pic16_dump_section): relocatable and absolute uninitialized
5744 data are now emitted in sorted order to reduce section naming,
5745 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5746 weren't marked as being in the access bank,
5748 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5750 Added portion of GNU PIC Library under the directory
5751 device/include/pic16 and device/lib/pic16. These files
5752 contain the declarations of SFRs for the PIC18Fxx2 devices.
5753 The directory is initialized via configure from toplevel.
5755 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5757 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5783 all over. Telling LaTeX to be less strict with word spacing
5784 to better keep the right margin. Changed some notes about
5785 maintainance of the ports in section 3.2.1 - is it OK like this?
5787 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5827 * src/pic16/peeph.def: all peepholes with movff are commented out,
5828 because there is a problem in the pcode peep optimizer,
5829 * src/pic16/ralloc.c: the register allocator can now reuse local

5922 include information about variables allocated to the overlay
5925 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5927 * as/mcs51/lkmain.c: Help about -Y option

5939 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5941 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5942 (default behaviour).
5944 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5946 A python script to validate compiler diagnostic messages. It can be
5947 used to verify that sdcc complains about bad c source code and
5948 gives a good location of the error.
5949 * support/valdiag/Makefile,
5950 * support/valdiag/valdiag.py,
5951 * support/valdiag/tests/*
5953 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5955 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5966 * src/common.h: added ifndef/define/endif macros
5967 around the header file.
5968 Bug reported from Jesus Calvino-Fraga
5970 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5972 * sdcc.spec: updated
5973 * device/include/Makefile.in: don't install CVS directories
5974 * device/lib/Makefile.in: added removal of CVS directories after install
5975 * doc/Makefile: fixed install, added local_icons
5976 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5977 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5978 * src/ds390/gen.c (genRightShift): fixed bug #870788
5979 * src/SDCCast.c (decorateType): fixed bug #870781
5981 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5983 PIC16 port related changes:
5984 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5985 added variable stackPos,
5987 * gen.c: genCall, assignResultValue: added support for
5988 pushing/retrieving function parameters to/from stack,
5989 genFunction,genEndFunction: setup stack frame for the
5991 genAddrOf: will be changed according to bug 863624
5993 * added files genutils.c and genutils.h which contain gen*
5994 debugged and optimised functions extracted from gen.c
5996 * glue.c: added variable 'externs' which holds extern symbols,
5997 pic16emitRegularMap: is modified to properly handle relocatable
5998 symbols under the new scheme,
5999 pic16createInterruptVect: is modified
6000 pic16printPublics: is modified to emit 'global' assembler directives,
6001 added pic16_printExterns to print extern symbols,
6002 pic16glue: initializes stack/frame pointer in the beginning of
6003 the assembly output. Temporary hack, will be corrected later,
6004 because gplink yet does not support stack and SDCC does not
6005 yet support a type of crt0.o object to create the final binary.
6007 * Removed many lines that contain 8051 legacy code.
6008 * The code is finally placed under a 'code' directive.
6009 * Added port specific options.
6011 * _process_pragma: simplified since now we do not need *special*
6012 include file to define SFR registers. But a separate header
6013 will be needed. This will be developed later.
6014 * _pic16_parseOptions: added, parses port specific options:
6015 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6016 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6017 --preplace-udata-with=
6019 * _pic16_setDefaultOptions: modified to initialize section names,
6020 but hack is temporarly out of order since it needs improvement.
6021 * _pic16_genAssemblerPreamble: configuration words are emitted by
6022 their address instead of their name. This part is incomplete and
6023 supports only the 18Fxx2 devices. Other devices will emit an error
6024 during assembly since they do not contain the same set of config
6026 * _pic16_genIVT: is modified,
6028 * pcode.c: added definitions for some hardware registers that are needed
6030 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6031 All PCI entries are updated. Now LFSR is supported.
6032 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6033 * added pic16_newpCodeOpLit2 to support instructions with
6034 two literal arguments
6035 * pic16_pCode2str: corrected code that emits assembler instructions
6036 with two literal operands and those that have an access bit modifier
6037 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6038 this fixes a bug which caused some labels to be lost, when an
6039 assembler directive was added, i.e. banksel,
6040 * pic16_FixRegisterBanking: improved logic that causes the insertion
6042 * InlineFunction: functions that are called once, are not any more
6043 inlined. This can be a port option in the future,
6045 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6047 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6048 hold the corresponding uninitialized symbols,
6049 * pic16_allocProcessorRegister: registers have explicit marked the
6051 * pic16_allocInternalRegister: registers are explicit marked as
6053 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6054 processing list, so bit registers were lost,
6057 * ralloc.h: added field 'accessBank' and original symbol operand
6058 in register definition,
6059 * removed the field isMapped from register definition,
6061 ** Several functions have been removed from various sources:
6062 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6063 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6064 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6065 pic16_assignRelocatableRegisters
6067 ** others have been introduced:
6068 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6069 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6071 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6073 * support/scripts/inc2h.pl: changed definition of BIT_AT
6074 to emit 'sbit at' instead of 'bit at'. This was a request.
6076 PIC16 port related preliminary changes:
6077 * gen.c: prefixed function popRegFromString with
6078 pic16_ and all references to it corrected
6079 * pcode.c: all pic16_pc_* hardware registers prefixed
6080 with underscore (_),
6081 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6082 * ralloc.c: newReg(): when register is REG_SFR then
6083 set address to rIdx,
6084 pic16_allocProcessorRegister(): marks register wasUsed=0
6085 pic16_writeUsedRegs(): added a call to assign processor
6086 registers via pic16_assignFixedRegisters
6088 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6090 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6091 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6092 variables in unused register banks. Also the SSEG is placed
6093 wherever there is enough space for it, and IDATA can be anywhere
6094 in internal RAM. For now compile using -Wl-Y[stack_size].
6095 The mem file is different for this option as well, since it
6096 makes no sense of talking about DSEG lenght.
6098 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6100 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6101 in certain cases, e.g. when ROM assignment, patch provided
6102 from Albert den Haan.
6104 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7127 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7128 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7147 A few small changes that speed up the peephole optimizer.
7151 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7153 Try to make the peephole optimizer smarter by maintaining
7154 an association between the assembly source code and the
7155 iCodes that originated them. Put this information to use
7156 with a new peephole rule condition "notVolatile" so that
7157 the rules can be aggressive yet still safe.
7162 * src/mcs51/peeph.def
7164 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7168 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7170 if the left or right operand symbols have the accuse flag set.
7172 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7174 Changed the type of the result of the ! (NOT) operator to char;
7175 previously it returned the same type as the source. This allows
7176 us to eliminate all the genFloatNot functions (all of its target
7177 implementations were very buggy) since !float can use the same
7180 * src/SDCCicode.c (ast2iCode): ! returns char

7182 * src/ds390/gen.c (genNot, genNotFloat),
7183 * src/z80/gen.c (genNot, genNotFloat),
7184 * src/pic/gen.c (genNot, genNotFloat),

7189 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7190 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7191 during interrupts. Ensure WSAVE is located at a shared bank address.
7192 2. Fixed page selection in some places
7193 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7194 the registers name strings.
7195 4. Fixed "signed / unsigned compare" compiler warnings.
7196 5. The PIC port manages its own allocation of the general purpose
7197 registers, but makes no attempt to reuse them. As a result when
7198 compiling it soon runs out of general purpose registers. Some
7199 additional code was added to the files pcode.c and device.c to walk
7200 through the function call tree and rename the registers so that they
7210 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7211 genPlus() & genMinus() when the result is the same as left or right

7217 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7219 Made bitfield a distinct type from bit so that bitfields
7220 convert as per ANSI C and bits retain their traditional
7221 boolean style behaviour. Implemented bitfield support in
7229 * src/ds390/gen.c: bit v bitfield split
7230 * src/z80/gen.c: New support for bitfields
7231 * support/regression/tests/bitfields.c: reenabled z80,
7234 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7236 Rules 246.x, 247.x relate to bitfields, the others speed up
7237 access to xdata mapped I/O devices.
7239 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7241 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7243 Cleaned up genPackBits and genUnpackBits and added two helper
7244 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7245 for literal assignments in genPackBits (thanks to Frieder for
7251 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7253 Fixed bug #748310 (pointer to function type mishandled when the
7254 function name is omitted). Also fixed a SIGSEGV when a function
7255 attribute (reentrant, etc) is used on a non-function or on a
7256 function but misplaced before the parameter list.

7283 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7285 Made the constant following the "interrupt" keyword optional. If
7286 omitted, the function will not automatically be given an entry
7287 in the interrupt vector table (similar to #pragma NOIV, but
7288 less syntacticly kludgy). The interrupt number is also now
7289 range checked. Also fixed a bug in the high order bit example

7792 * src/pic16/pcode.c: Cleaned warnings
7793 * src/pic16/pcodeflow.c: Cleaned warnings
7794 * src/pic16/pcoderegs.c: Cleaned warnings

7810 it can be defined with CFLAGS when running configure
7811 * src/SDCCmain.c: fixed compiling + linking with object files
7813 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7815 * configure.in: configure for pic16 port,
7816 added --disable-pic16-port
7817 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7818 * src/SDCCmain.c: linkOptions is changed to set *,
7819 added if/endif conditional macros to remove options help
7820 messages from optionsTable when a port is not configured, added
7821 support for the PIc16 port in the ports table, when executing
7822 the compiler with no port specified on command line, a default
7823 port is selected with the new macro DEFAULT_PORT which is
7824 defined in port.h, in setDefaultOptions() linkOptions is removed
7825 from initialization assignment, since now it is a set,
7826 parseCmdLine uses setParseWithComma for linkOptions, in
7827 linkEdit() linkOptions are accessed with new function indexSet()
7828 which returns the i'th item of a set variable. See SDCCset.c, in
7829 linkEdit() when calling buildCmdLine(), added linkOptions as
7830 last argument. Now users can pass arguments to gplink via the
7831 -Wl option, main() uses pic16glue() to glue up pic16 programs

7843 * src/pic16/glue.c: commented out some error producing lines
7844 * src/pic16/main.c: __config directives are commented out to stop
7845 gpasm complaining and test the linkage with gplink, _linkCmd and
7846 _asmCmd changed to be more gplink and gpasm friendly
7847 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7848 produced an error when parsed, peep rule 12 is added to utilize
7849 movff, but it is commented out since the pCode does not support
7850 yet a command with 2 address arguments
7852 2003-05-18 <johan AT balder>
7854 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7881 2003-05-11 Borut Razem <borut.razem AT siol.net>
7883 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7884 the path of bin directory, so that PATH is the only env. variable, which has to be set

8889 * src/SDCCicode.c: fixed array add
8891 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8892 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8893 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8895 2003-01-04 <johan AT balder>
8897 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8899 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8900 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8902 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8912 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8913 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8915 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8917 * in \sdcc\as\mcs51\ changed these files in order to create an
8918 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8919 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8920 following files to include the previous two files: aslink.dsp,
8921 Makefile.aslink, Makefile.bcc, and Makefile.in.
8923 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8924 .adb instead of .cdb
8926 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8928 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8929 value from option --iram-size.
8931 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8933 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8936 2002-09-18 <wiml AT hhhh.org>
8938 * SDCClrange.h: exposed setFromRange() and setToRange()
8939 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8940 packRegsForAccUse() (bug 542397)
8941 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8942 multiple times and emitting the fetch operations more than once
8943 added aopGetUsesAcc() function to allow binary operators to
8944 fetch their operands in the correct order; made genMinus() emit
8945 compact code for X = LITERAL - Y
8947 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8948 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8949 sprintf() in line 1267.
8951 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8952 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8955 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8956 Changes to aslink (All the changes are marked with 'JCF'):
8958 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8961 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8962 area BSEG. Also moves, if possible, the DATA area down into the internal
8963 ram so more space is available.
8965 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8968 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8969 not bytes. Function summary() which creates a memory usage summary
8970 file with extension .mem. Reports of overlaping stack and small stack
8971 size. If the space for the stack is less than 16 bytes aslink trows a
8974 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8975 the 8051. Option 'y' for memory summary output file.
8977 Changes to sdcc (All the changes are marked with 'JCF'):
8979 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8981 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8982 overlaying area for it (uses RegBankUsed[4]).
8984 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8985 bank zero as used by default. By default aslink locates the stack
8986 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8987 the creation of the .mem file. Delegates the allocation of data area
8988 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8989 the begining of the stack area to aslink.
8991 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8992 glue() in SDCCglue.c creates an area for it.
8994 2002-09-03 Borut Razem <borut.razem AT siol.net>
8995 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8996 sdcc/src/pic/glue.c:
8997 introduced atexit() handler for teporay files removal in case of
8998 errors, assertions, ...
9000 2002-08-29 Borut Razem <borut.razem AT siol.net>
9001 * sdcc/support/cpp2/auto-host_vc_in.h:
9002 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9003 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9004 Maybe there is a similar problem with BORLANDC? It should be checked!
9006 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9007 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9008 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9009 was not executed, and the compiler (cl) launched a warning:
9010 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9012 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9013 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9015 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9016 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9018 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9019 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9021 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9022 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9023 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9024 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9025 - added Release configuration in VS projects
9026 - review of compiler an linker options
9027 - VC .exe files are generated in bin_vc directory, not to interfere
9028 with binaries generated from other projects (cygwin, mingw, bcc ...)
9030 * sdcc/src/yacc.dsp: added
9032 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9033 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9034 and insert the version number definitions from .version
9036 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9038 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9039 added - genarate auto-host.h using auto-host_vc_in.h as template
9042 removed from CVS, generated automatically
9044 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9045 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9047 2002-08-11 Borut Razem <borut.razem AT siol.net>
9048 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9050 2002-08-10 Borut Razem <borut.razem AT siol.net>
9051 * src/SDCCmain.c (main):
9052 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9053 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9054 The consequence was that some temporary files were not removed.
9057 unification of code in functions tempfilename() and tempfile():
9058 function tempnam() is defined in Visual Studio 6.0 and .NET
9060 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9062 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9063 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9064 - removed compiler command line option /WX: Treats all warnings as errors
9065 - update a list of source files, included into the project
9067 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9068 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9069 changed project type to Generic Project so that can be correcly converted to VS.NET project
9071 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9073 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9075 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings

9266 Previous fix was not good. basic blocks that have "break" or "return" are
9267 not really partof a loop , but live ranges used in these blocks should
9268 be live thru the entire loop, so set partOfLoop but don't add them to
