1764 on rIfx (genCmp was broken)
1766 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1768 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1769 * src/z80/main.c (_keywords[]),
1770 * src/SDCCglobal.h (struct options),
1772 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1773 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1774 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1775 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1776 always available in leading double underscore form. The C99 support is
1777 mostly missing, but it's a start.
1778 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1779 reserved identifier "__data".
1781 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1827 2005-03-20 Borut Razem <borut.razem AT siol.net>
1829 * support/scripts/inc2h.pl: WIN32 port

1857 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1859 * device/lib/printf_large.c: removed inline assembly for portability and
1860 readability. Use printf_fast if speed or size are more important.
1861 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1862 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1864 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1866 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1867 prevent compiler warning
1869 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1871 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1872 moved to level 0 and declared as static. Also they are explicit
1873 placed in access bank. This was necessery because some times they
1874 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1875 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1876 optimizations. Currently only compare to unsigned char is implemented,
1877 * src/pic16/gen.c: added fReturnIdx array,
1878 * (struct resolvedIfx) is moved to gen.h and made public,
1879 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1880 * (aopForSym): added an optimization to directly store in stack of
1881 the operand of a SEND iCode,
1882 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1883 but as registers instead (AOP_REG) using the fReturnIdx array,
1884 * (pic16_freeAsmop): remove the freed register from the
1885 _G.sregsAlloc field,
1886 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1887 a compare of 'WREG',
1888 * (pic16_popGetTempRegCond): changed function prototype, now
1889 function takes also a bitVector argument v which holds the current
1890 set of registers that are allocated for stack access by aopForSym,
1891 registers allocated in aopForSym for accessing stack symbols are not
1892 any more part of the functions usedRegs field,
1893 * (genCall): some times aopOp is called for a stack variable to be
1894 send, aopForSym might perform the push, if this is true make sure
1895 that genCall doesn't push the variable twice by testing _G.resDirect,
1896 * (genFunction): changed testing for unspecified interrupt number
1897 from 256 to INTNO_UNSPEC,
1898 * modified selection scheme of frame pointer generation. Previously
1899 if function did use local registers a frame pointer was generated,
1900 now a frame pointer is generated only if function has arguments
1901 (that need PLUSW2 register access), or has stack arguments, or the
1902 compiler is not instructed to omit the frame pointer,
1903 * (genEndFunction): before restoring local registers that were saved
1904 in the function preamble, also restore the registers that *might*
1905 have been allocated for stack access,
1906 * (genRet): removed some old comments,
1907 * (genCmp, the active (RN's) version): added a call to the
1908 pic16_genCmp_special function to perform the compare with a more
1909 robust and optimized way,
1910 * (genInline): a feature has been added in inline code generation,
1911 which allows a wildcard variable substitution when writing inline
1912 assembly. Code is incomplete and experimental therefore undocumented,
1913 * (genCast): changed order of aopOp for result and right to allow
1914 aopForSym to directly load the result if possible,
1915 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1916 perform an optimized compare on some selected special occasions,
1917 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1918 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1919 generate an IVT any more,
1920 * src/pic16/main.c (pic16_optionsTable): added command line option
1922 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1923 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1925 * src/pic16/NOTES: Raphael Neider added in list of active developers
1926 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1927 jumptable_end to prevent bug #,
1928 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1929 inCond and outCond fields,
1930 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1931 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1932 turn off register spilling,
1933 * (packRegsForOneUse): synced with other ports' versions although it
1934 is not used currently,
1935 * (pic16_packRegisters): added an optimization while reading
1936 structure bitfields, some registers may be saved (malloc code is
1937 decreased by 80 bytes)
1939 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1941 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1942 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1943 this can be optimized more?
1945 2005-03-10 Raphael Neider <rneider AT web.de>
1947 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1948 genNearPointerGet): (hopefully) fixed access to bitfields via
1949 pointers (p->bitN = x; and x = p->bitN; failed)
1951 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2128 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2129 (sizeof(sectNames) changed to sizeof(sectName))

2137 of (byte sized) temporaries (assign them to WREG for now)
2138 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2139 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2140 this might fix SIGSEGVs on MinGW...
2141 * src/SDCCopt.c (killDeadCode): restored original behaviour
2142 (volatile operands might get thrown away though)
2144 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2583 Adding support for replacing ljmps with sjmps in jumptables
2584 generated for switch statements. For now you need to set the
2585 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2586 Now 4 algorithms for mcs51 jumptable generation are used:

2608 * src/pic16/genarith.c,
2611 * src/pic16/pcode.c: applied patches #1068154 and #1070213
2613 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2615 Large cummulative patch for pic16 port.
2616 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2617 to call when a stack overflow occurs,
2618 * (malloc.h): added CVS Id tag,
2619 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2621 * added libc directory. The current version of LibC contains string
2622 functions, ctype functions and macros and some functions of the
2623 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2624 be extensively tested in the future. Standard disclaimer here.
2625 Library is not automatically build yet. But one can build it by
2626 invoking 'make' inside the libc directory.
2627 * added ADC library under libio. Preliminary version yet.
2629 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2630 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2631 aopForRemat() now and not by pic16_aopOp(),
2632 * (pic16_popGetTempReg): removed warning messgae when allocating
2633 temporary registers, its a buggy feature and will be removed,
2634 * (pic16_popGet): set register instance field in AOP_CRY,
2635 * (pic16_outBitC): fixed for results in size greater than 1,
2636 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2637 * (pic16_storeForReturn): optimized return of 0,
2638 * (genCmp): experimental code for new genCmp which uses PIC18's
2639 special compare&skip instructions. Initial tests fail some times
2640 with variables grater than 1 byte in size, so new code is disabled,
2641 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2643 * (genCast): began a fix to optimize the casting of a bit to another
2644 bit, now assigning a bitfield to another bitfield will fail, sorry,
2645 * src/pic16/main.c: disabled the use of lr-support feature,
2646 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2647 * added some function prototypes, added function _debugf prototype,
2648 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2649 bits with offset (case PO_GPR_BIT),
2650 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2652 * (isBankInstruction): modified to return 0 for no banking instruction,
2653 and 1 for banking instruction,
2654 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2655 caused stop processing pCodes after a inline assembly block,
2656 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2657 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2658 registers when it shouldn't,
2659 * src/pic16/ralloc.c (allocReg): add preliminary support for
2660 supporting a limited set of temporary registers,
2662 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2664 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2665 genDataPointerSet): ensure assignments always copy in MSB to LSB
2667 (loadRegFromAop): recognize CLRH optimization,
2668 (genFunction): optimize RECEIVE iCodes in reentrant functions
2670 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2672 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2673 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2675 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

5670 loaded with the linker search paths (-L arguments) and the libraries
5671 to be linked with the current source (-l arguments). Changes
5672 currently will affect only the pic16 port.
5673 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5674 include path the port specific paths and port specific libraries,
5675 * gplink command now contains the $3 argument,

5691 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
5693 Documenting changes from previous commits.
5694 * configure.in (version 1.56),
5695 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5696 when generating output files to configure the pic16 library,
5697 but now I've commented it out, since gputils aren't installed in the
5698 SF compile farm, so library won't compile
5700 * device/lib/Makefile.in (version 1.56): initially I've added in
5701 target 'all' the prerequestive 'model-pic16' so it compiled the
5702 pic16 library, but now I've commented it out for the same reasons
5704 * added targets 'model-pic16' and 'objects-pic16' to compile the
5706 * added target 'port-specific-objects-pic16' to handle the
5707 generated libraries and copy them into the build/ directory
5708 * added target 'clean-intermediate-pic16' to clean intermediate
5709 files into pic16 directory
5710 * in target 'installdirs' added line to create directory pic16 in
5711 the installation path
5713 * device/include/Makefile.in (version 1.11): in target 'install'
5714 added lines to copy all header files to installation path,
5715 * in target 'installdirs' added line create directory for pic16
5716 headers in the installation path
5718 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5731 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5732 option so that it actually works. Made it specific to the z80, since
5733 the gbz80 doesn't have these kinds of I/O ports.
5735 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5737 * device/include/z180.h,

5743 * device/lib/_strcmp.c,
5744 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5745 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5746 portmode; added deprecation warning for bank= and protmode= forms.
5747 Also, guard against buffer overflow.
5748 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5750 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5752 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
5753 changed interrupt vector table generation to only emit declared vectors.
5754 * device/include/Makefile.in: added missing backslash
5755 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
5757 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5759 Mainly changes to support compilation of the device libraries
5760 * src/pic16/device.c: stack is allocated via symbol and not
5761 via literal number. The symbol is placed in the corresponding
5762 position of the data ram
5763 * (pic16_dump_section): relocatable and absolute uninitialized
5764 data are now emitted in sorted order to reduce section naming,
5765 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5766 weren't marked as being in the access bank,
5768 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5770 Added portion of GNU PIC Library under the directory
5771 device/include/pic16 and device/lib/pic16. These files
5772 contain the declarations of SFRs for the PIC18Fxx2 devices.
5773 The directory is initialized via configure from toplevel.
5775 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5777 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5778 the spilllocations to be compared correctly
5780 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
5782 * src/SDCCast.c (decorateType): fixed bug introduced today
5784 2004-01-12 Borut Razem <borut.razem AT siol.net>

5800 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5802 * doc/sdccman.lyx: Moved and added some sections, small changes
5803 all over. Telling LaTeX to be less strict with word spacing
5804 to better keep the right margin. Changed some notes about
5805 maintainance of the ports in section 3.2.1 - is it OK like this?
5807 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5844 UPPER for immediate operands,
5845 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5847 * src/pic16/peeph.def: all peepholes with movff are commented out,
5848 because there is a problem in the pcode peep optimizer,
5849 * src/pic16/ralloc.c: the register allocator can now reuse local
5850 function symbols for another function. This saves register usage.
5851 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5853 Added file src/pic16/NOTES with information about program writing on
5854 the current port version.

5913 * (pic14emitOverlay): modified to emit a commented overlay segment
5914 directive when no overlay data exist
5915 * (picglue): modified to emit uninitialized data segment
5916 according to udata_section_name

5942 include information about variables allocated to the overlay
5945 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5947 * as/mcs51/lkmain.c: Help about -Y option

5959 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5961 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5962 (default behaviour).
5964 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5966 A python script to validate compiler diagnostic messages. It can be
5967 used to verify that sdcc complains about bad c source code and
5968 gives a good location of the error.
5969 * support/valdiag/Makefile,
5970 * support/valdiag/valdiag.py,
5971 * support/valdiag/tests/*

5988 Bug reported from Jesus Calvino-Fraga
5990 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5992 * sdcc.spec: updated
5993 * device/include/Makefile.in: don't install CVS directories
5994 * device/lib/Makefile.in: added removal of CVS directories after install
5995 * doc/Makefile: fixed install, added local_icons
5996 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5997 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5998 * src/ds390/gen.c (genRightShift): fixed bug #870788
5999 * src/SDCCast.c (decorateType): fixed bug #870781
6001 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6003 PIC16 port related changes:
6004 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6005 added variable stackPos,
6007 * gen.c: genCall, assignResultValue: added support for
6008 pushing/retrieving function parameters to/from stack,
6009 genFunction,genEndFunction: setup stack frame for the
6011 genAddrOf: will be changed according to bug 863624
6013 * added files genutils.c and genutils.h which contain gen*
6014 debugged and optimised functions extracted from gen.c
6016 * glue.c: added variable 'externs' which holds extern symbols,
6017 pic16emitRegularMap: is modified to properly handle relocatable
6018 symbols under the new scheme,
6019 pic16createInterruptVect: is modified
6020 pic16printPublics: is modified to emit 'global' assembler directives,
6021 added pic16_printExterns to print extern symbols,
6022 pic16glue: initializes stack/frame pointer in the beginning of
6023 the assembly output. Temporary hack, will be corrected later,
6024 because gplink yet does not support stack and SDCC does not
6025 yet support a type of crt0.o object to create the final binary.
6027 * Removed many lines that contain 8051 legacy code.
6028 * The code is finally placed under a 'code' directive.
6029 * Added port specific options.
6031 * _process_pragma: simplified since now we do not need *special*
6032 include file to define SFR registers. But a separate header
6033 will be needed. This will be developed later.
6034 * _pic16_parseOptions: added, parses port specific options:
6035 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6036 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6037 --preplace-udata-with=
6039 * _pic16_setDefaultOptions: modified to initialize section names,
6040 but hack is temporarly out of order since it needs improvement.
6041 * _pic16_genAssemblerPreamble: configuration words are emitted by
6042 their address instead of their name. This part is incomplete and
6043 supports only the 18Fxx2 devices. Other devices will emit an error
6044 during assembly since they do not contain the same set of config
6046 * _pic16_genIVT: is modified,
6048 * pcode.c: added definitions for some hardware registers that are needed
6050 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6051 All PCI entries are updated. Now LFSR is supported.
6052 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6053 * added pic16_newpCodeOpLit2 to support instructions with
6054 two literal arguments
6055 * pic16_pCode2str: corrected code that emits assembler instructions
6056 with two literal operands and those that have an access bit modifier
6057 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6058 this fixes a bug which caused some labels to be lost, when an
6059 assembler directive was added, i.e. banksel,
6060 * pic16_FixRegisterBanking: improved logic that causes the insertion
6062 * InlineFunction: functions that are called once, are not any more
6063 inlined. This can be a port option in the future,
6065 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6067 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6068 hold the corresponding uninitialized symbols,
6069 * pic16_allocProcessorRegister: registers have explicit marked the
6071 * pic16_allocInternalRegister: registers are explicit marked as
6073 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6074 processing list, so bit registers were lost,
6077 * ralloc.h: added field 'accessBank' and original symbol operand
6078 in register definition,
6079 * removed the field isMapped from register definition,
6081 ** Several functions have been removed from various sources:
6082 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6083 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6084 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6085 pic16_assignRelocatableRegisters
6087 ** others have been introduced:
6088 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6089 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6091 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6093 * support/scripts/inc2h.pl: changed definition of BIT_AT
6094 to emit 'sbit at' instead of 'bit at'. This was a request.
6096 PIC16 port related preliminary changes:
6097 * gen.c: prefixed function popRegFromString with
6098 pic16_ and all references to it corrected
6099 * pcode.c: all pic16_pc_* hardware registers prefixed
6100 with underscore (_),
6101 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6102 * ralloc.c: newReg(): when register is REG_SFR then
6103 set address to rIdx,
6104 pic16_allocProcessorRegister(): marks register wasUsed=0
6105 pic16_writeUsedRegs(): added a call to assign processor
6106 registers via pic16_assignFixedRegisters
6108 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6110 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6111 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6112 variables in unused register banks. Also the SSEG is placed
6113 wherever there is enough space for it, and IDATA can be anywhere
6114 in internal RAM. For now compile using -Wl-Y[stack_size].
6115 The mem file is different for this option as well, since it
6116 makes no sense of talking about DSEG lenght.
6118 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6120 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6121 in certain cases, e.g. when ROM assignment, patch provided
6122 from Albert den Haan.
6124 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7167 A few small changes that speed up the peephole optimizer.
7171 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7173 Try to make the peephole optimizer smarter by maintaining
7174 an association between the assembly source code and the
7175 iCodes that originated them. Put this information to use
7176 with a new peephole rule condition "notVolatile" so that
7177 the rules can be aggressive yet still safe.
7182 * src/mcs51/peeph.def
7184 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7188 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7189 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7190 if the left or right operand symbols have the accuse flag set.
7192 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7194 Changed the type of the result of the ! (NOT) operator to char;
7195 previously it returned the same type as the source. This allows
7196 us to eliminate all the genFloatNot functions (all of its target
7197 implementations were very buggy) since !float can use the same
7200 * src/SDCCicode.c (ast2iCode): ! returns char

7209 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7210 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7211 during interrupts. Ensure WSAVE is located at a shared bank address.
7212 2. Fixed page selection in some places
7213 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7214 the registers name strings.
7215 4. Fixed "signed / unsigned compare" compiler warnings.
7216 5. The PIC port manages its own allocation of the general purpose
7217 registers, but makes no attempt to reuse them. As a result when
7218 compiling it soon runs out of general purpose registers. Some
7219 additional code was added to the files pcode.c and device.c to walk
7220 through the function call tree and rename the registers so that they
7230 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7237 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7239 Made bitfield a distinct type from bit so that bitfields
7240 convert as per ANSI C and bits retain their traditional
7241 boolean style behaviour. Implemented bitfield support in
7249 * src/ds390/gen.c: bit v bitfield split
7250 * src/z80/gen.c: New support for bitfields
7251 * support/regression/tests/bitfields.c: reenabled z80,
7254 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7256 Rules 246.x, 247.x relate to bitfields, the others speed up
7257 access to xdata mapped I/O devices.
7259 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7261 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7263 Cleaned up genPackBits and genUnpackBits and added two helper
7264 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7265 for literal assignments in genPackBits (thanks to Frieder for
7271 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7273 Fixed bug #748310 (pointer to function type mishandled when the
7274 function name is omitted). Also fixed a SIGSEGV when a function
7275 attribute (reentrant, etc) is used on a non-function or on a
7276 function but misplaced before the parameter list.

7303 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7305 Made the constant following the "interrupt" keyword optional. If
7306 omitted, the function will not automatically be given an entry
7307 in the interrupt vector table (similar to #pragma NOIV, but
7308 less syntacticly kludgy). The interrupt number is also now
7309 range checked. Also fixed a bug in the high order bit example

7778 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
7779 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
7780 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

7785 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7786 the regression tests I'm not brave enough to enable 245.b, 245.c
7787 * doc/sdccman.lyx: added latex preamble for hyperref package.
7788 Using pdflatex this will give you a hyperlinked pdf file with
7789 bookmarks. (prepend '%' before /usepackage if this breaks something)

7836 added --disable-pic16-port
7837 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7838 * src/SDCCmain.c: linkOptions is changed to set *,
7839 added if/endif conditional macros to remove options help
7840 messages from optionsTable when a port is not configured, added
7841 support for the PIc16 port in the ports table, when executing
7842 the compiler with no port specified on command line, a default
7843 port is selected with the new macro DEFAULT_PORT which is
7844 defined in port.h, in setDefaultOptions() linkOptions is removed
7845 from initialization assignment, since now it is a set,
7846 parseCmdLine uses setParseWithComma for linkOptions, in
7847 linkEdit() linkOptions are accessed with new function indexSet()
7848 which returns the i'th item of a set variable. See SDCCset.c, in
7849 linkEdit() when calling buildCmdLine(), added linkOptions as
7850 last argument. Now users can pass arguments to gplink via the
7851 -Wl option, main() uses pic16glue() to glue up pic16 programs

7863 * src/pic16/glue.c: commented out some error producing lines
7864 * src/pic16/main.c: __config directives are commented out to stop
7865 gpasm complaining and test the linkage with gplink, _linkCmd and
7866 _asmCmd changed to be more gplink and gpasm friendly
7867 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7868 produced an error when parsed, peep rule 12 is added to utilize
7869 movff, but it is commented out since the pCode does not support
7870 yet a command with 2 address arguments
7872 2003-05-18 <johan AT balder>
7874 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7899 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7901 2003-05-11 Borut Razem <borut.razem AT siol.net>
7903 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7904 the path of bin directory, so that PATH is the only env. variable, which has to be set
7905 in case of standard installation.
7906 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8909 * src/SDCCicode.c: fixed array add
8911 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8912 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8913 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8915 2003-01-04 <johan AT balder>
8917 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8919 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8920 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8932 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8933 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8935 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8937 * in \sdcc\as\mcs51\ changed these files in order to create an
8938 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8939 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8940 following files to include the previous two files: aslink.dsp,
8941 Makefile.aslink, Makefile.bcc, and Makefile.in.
8943 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8944 .adb instead of .cdb
8946 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8948 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8949 value from option --iram-size.
8951 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8953 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8956 2002-09-18 <wiml AT hhhh.org>
8958 * SDCClrange.h: exposed setFromRange() and setToRange()
8959 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8960 packRegsForAccUse() (bug 542397)
8961 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8962 multiple times and emitting the fetch operations more than once
8963 added aopGetUsesAcc() function to allow binary operators to
8964 fetch their operands in the correct order; made genMinus() emit
8965 compact code for X = LITERAL - Y
8967 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8968 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8969 sprintf() in line 1267.
8971 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8972 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8975 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8976 Changes to aslink (All the changes are marked with 'JCF'):
8978 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8981 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8982 area BSEG. Also moves, if possible, the DATA area down into the internal
8983 ram so more space is available.
8985 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8988 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8989 not bytes. Function summary() which creates a memory usage summary
8990 file with extension .mem. Reports of overlaping stack and small stack
8991 size. If the space for the stack is less than 16 bytes aslink trows a
8994 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8995 the 8051. Option 'y' for memory summary output file.
8997 Changes to sdcc (All the changes are marked with 'JCF'):
8999 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9001 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9002 overlaying area for it (uses RegBankUsed[4]).
9004 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9005 bank zero as used by default. By default aslink locates the stack
9006 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9007 the creation of the .mem file. Delegates the allocation of data area
9008 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9009 the begining of the stack area to aslink.
9011 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9012 glue() in SDCCglue.c creates an area for it.
9014 2002-09-03 Borut Razem <borut.razem AT siol.net>
9015 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9016 sdcc/src/pic/glue.c:
9017 introduced atexit() handler for teporay files removal in case of
9018 errors, assertions, ...
9020 2002-08-29 Borut Razem <borut.razem AT siol.net>
9021 * sdcc/support/cpp2/auto-host_vc_in.h:
9022 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9023 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9024 Maybe there is a similar problem with BORLANDC? It should be checked!
9026 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9027 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9028 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9029 was not executed, and the compiler (cl) launched a warning:
9030 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9032 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9033 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9035 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9036 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9038 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9039 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9041 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9042 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9043 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9044 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9045 - added Release configuration in VS projects
9046 - review of compiler an linker options
9047 - VC .exe files are generated in bin_vc directory, not to interfere
9048 with binaries generated from other projects (cygwin, mingw, bcc ...)
9050 * sdcc/src/yacc.dsp: added
9052 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9053 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9054 and insert the version number definitions from .version
9056 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9058 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9059 added - genarate auto-host.h using auto-host_vc_in.h as template
9062 removed from CVS, generated automatically
9064 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9065 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9067 2002-08-11 Borut Razem <borut.razem AT siol.net>
9068 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9070 2002-08-10 Borut Razem <borut.razem AT siol.net>
9071 * src/SDCCmain.c (main):
9072 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9073 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9074 The consequence was that some temporary files were not removed.
9077 unification of code in functions tempfilename() and tempfile():
9078 function tempnam() is defined in Visual Studio 6.0 and .NET
9080 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9082 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9083 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9084 - removed compiler command line option /WX: Treats all warnings as errors
9085 - update a list of source files, included into the project
9087 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9101 added newline in the def file to keep MSC compiler satisfied
9103 * sdcc/src/z80/gen.c:
9104 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9105 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC

9286 Previous fix was not good. basic blocks that have "break" or "return" are
9287 not really partof a loop , but live ranges used in these blocks should
9288 be live thru the entire loop, so set partOfLoop but don't add them to
