1759 on rIfx (genCmp was broken)
1761 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1763 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1764 * src/z80/main.c (_keywords[]),
1765 * src/SDCCglobal.h (struct options),
1767 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1768 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1769 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1770 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1771 always available in leading double underscore form. The C99 support is
1772 mostly missing, but it's a start.
1773 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1774 reserved identifier "__data".
1776 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1852 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1854 * device/lib/printf_large.c: removed inline assembly for portability and
1855 readability. Use printf_fast if speed or size are more important.
1856 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1857 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1859 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1861 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1862 prevent compiler warning
1864 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1866 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1867 moved to level 0 and declared as static. Also they are explicit
1868 placed in access bank. This was necessery because some times they
1869 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1870 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1871 optimizations. Currently only compare to unsigned char is implemented,
1872 * src/pic16/gen.c: added fReturnIdx array,
1873 * (struct resolvedIfx) is moved to gen.h and made public,
1874 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1875 * (aopForSym): added an optimization to directly store in stack of
1876 the operand of a SEND iCode,
1877 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1878 but as registers instead (AOP_REG) using the fReturnIdx array,
1879 * (pic16_freeAsmop): remove the freed register from the
1880 _G.sregsAlloc field,
1881 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1882 a compare of 'WREG',
1883 * (pic16_popGetTempRegCond): changed function prototype, now
1884 function takes also a bitVector argument v which holds the current
1885 set of registers that are allocated for stack access by aopForSym,
1886 registers allocated in aopForSym for accessing stack symbols are not
1887 any more part of the functions usedRegs field,
1888 * (genCall): some times aopOp is called for a stack variable to be
1889 send, aopForSym might perform the push, if this is true make sure
1890 that genCall doesn't push the variable twice by testing _G.resDirect,
1891 * (genFunction): changed testing for unspecified interrupt number
1892 from 256 to INTNO_UNSPEC,
1893 * modified selection scheme of frame pointer generation. Previously
1894 if function did use local registers a frame pointer was generated,
1895 now a frame pointer is generated only if function has arguments
1896 (that need PLUSW2 register access), or has stack arguments, or the
1897 compiler is not instructed to omit the frame pointer,
1898 * (genEndFunction): before restoring local registers that were saved
1899 in the function preamble, also restore the registers that *might*
1900 have been allocated for stack access,
1901 * (genRet): removed some old comments,
1902 * (genCmp, the active (RN's) version): added a call to the
1903 pic16_genCmp_special function to perform the compare with a more
1904 robust and optimized way,
1905 * (genInline): a feature has been added in inline code generation,
1906 which allows a wildcard variable substitution when writing inline
1907 assembly. Code is incomplete and experimental therefore undocumented,
1908 * (genCast): changed order of aopOp for result and right to allow
1909 aopForSym to directly load the result if possible,
1910 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1911 perform an optimized compare on some selected special occasions,
1912 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1913 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1914 generate an IVT any more,
1915 * src/pic16/main.c (pic16_optionsTable): added command line option
1917 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1918 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1920 * src/pic16/NOTES: Raphael Neider added in list of active developers
1921 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1922 jumptable_end to prevent bug #,
1923 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1924 inCond and outCond fields,
1925 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1926 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1927 turn off register spilling,
1928 * (packRegsForOneUse): synced with other ports' versions although it
1929 is not used currently,
1930 * (pic16_packRegisters): added an optimization while reading
1931 structure bitfields, some registers may be saved (malloc code is
1932 decreased by 80 bytes)
1934 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1936 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1937 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1938 this can be optimized more?
1940 2005-03-10 Raphael Neider <rneider AT web.de>
1942 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1943 genNearPointerGet): (hopefully) fixed access to bitfields via
1944 pointers (p->bitN = x; and x = p->bitN; failed)
1946 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2123 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2124 (sizeof(sectNames) changed to sizeof(sectName))

2132 of (byte sized) temporaries (assign them to WREG for now)
2133 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2134 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2135 this might fix SIGSEGVs on MinGW...
2136 * src/SDCCopt.c (killDeadCode): restored original behaviour
2137 (volatile operands might get thrown away though)
2139 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2603 * src/pic16/genarith.c,
2606 * src/pic16/pcode.c: applied patches #1068154 and #1070213
2608 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2610 Large cummulative patch for pic16 port.
2611 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2612 to call when a stack overflow occurs,
2613 * (malloc.h): added CVS Id tag,
2614 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2616 * added libc directory. The current version of LibC contains string
2617 functions, ctype functions and macros and some functions of the
2618 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2619 be extensively tested in the future. Standard disclaimer here.
2620 Library is not automatically build yet. But one can build it by
2621 invoking 'make' inside the libc directory.
2622 * added ADC library under libio. Preliminary version yet.
2624 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2625 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2626 aopForRemat() now and not by pic16_aopOp(),
2627 * (pic16_popGetTempReg): removed warning messgae when allocating
2628 temporary registers, its a buggy feature and will be removed,
2629 * (pic16_popGet): set register instance field in AOP_CRY,
2630 * (pic16_outBitC): fixed for results in size greater than 1,
2631 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2632 * (pic16_storeForReturn): optimized return of 0,
2633 * (genCmp): experimental code for new genCmp which uses PIC18's
2634 special compare&skip instructions. Initial tests fail some times
2635 with variables grater than 1 byte in size, so new code is disabled,
2636 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2638 * (genCast): began a fix to optimize the casting of a bit to another
2639 bit, now assigning a bitfield to another bitfield will fail, sorry,
2640 * src/pic16/main.c: disabled the use of lr-support feature,
2641 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2642 * added some function prototypes, added function _debugf prototype,
2643 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2644 bits with offset (case PO_GPR_BIT),
2645 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2647 * (isBankInstruction): modified to return 0 for no banking instruction,
2648 and 1 for banking instruction,
2649 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2650 caused stop processing pCodes after a inline assembly block,
2651 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2652 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2653 registers when it shouldn't,
2654 * src/pic16/ralloc.c (allocReg): add preliminary support for
2655 supporting a limited set of temporary registers,
2657 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2659 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2660 genDataPointerSet): ensure assignments always copy in MSB to LSB
2662 (loadRegFromAop): recognize CLRH optimization,
2663 (genFunction): optimize RECEIVE iCodes in reentrant functions
2665 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2667 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2668 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2670 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2676 * device/lib/_gptrget.c (_gptrget),
2677 * device/lib/_gptrgetc.c (_gptrgetc),
2678 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2679 instead of sjmp to ret
2680 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2681 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2683 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5665 loaded with the linker search paths (-L arguments) and the libraries
5666 to be linked with the current source (-l arguments). Changes
5667 currently will affect only the pic16 port.
5668 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5669 include path the port specific paths and port specific libraries,

5690 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5691 when generating output files to configure the pic16 library,
5692 but now I've commented it out, since gputils aren't installed in the
5693 SF compile farm, so library won't compile
5695 * device/lib/Makefile.in (version 1.56): initially I've added in
5696 target 'all' the prerequestive 'model-pic16' so it compiled the
5697 pic16 library, but now I've commented it out for the same reasons
5699 * added targets 'model-pic16' and 'objects-pic16' to compile the
5701 * added target 'port-specific-objects-pic16' to handle the
5702 generated libraries and copy them into the build/ directory
5703 * added target 'clean-intermediate-pic16' to clean intermediate
5704 files into pic16 directory
5705 * in target 'installdirs' added line to create directory pic16 in
5706 the installation path
5708 * device/include/Makefile.in (version 1.11): in target 'install'
5709 added lines to copy all header files to installation path,
5710 * in target 'installdirs' added line create directory for pic16
5711 headers in the installation path

5726 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5727 option so that it actually works. Made it specific to the z80, since
5728 the gbz80 doesn't have these kinds of I/O ports.
5730 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5732 * device/include/z180.h,

5739 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5740 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5741 portmode; added deprecation warning for bank= and protmode= forms.
5742 Also, guard against buffer overflow.
5743 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5745 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5747 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

5754 Mainly changes to support compilation of the device libraries
5755 * src/pic16/device.c: stack is allocated via symbol and not
5756 via literal number. The symbol is placed in the corresponding
5757 position of the data ram
5758 * (pic16_dump_section): relocatable and absolute uninitialized
5759 data are now emitted in sorted order to reduce section naming,
5760 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5761 weren't marked as being in the access bank,
5763 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5765 Added portion of GNU PIC Library under the directory
5766 device/include/pic16 and device/lib/pic16. These files
5767 contain the declarations of SFRs for the PIC18Fxx2 devices.
5768 The directory is initialized via configure from toplevel.
5770 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5772 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5773 the spilllocations to be compared correctly

5797 * doc/sdccman.lyx: Moved and added some sections, small changes
5798 all over. Telling LaTeX to be less strict with word spacing
5799 to better keep the right margin. Changed some notes about
5800 maintainance of the ports in section 3.2.1 - is it OK like this?
5802 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5839 UPPER for immediate operands,
5840 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5842 * src/pic16/peeph.def: all peepholes with movff are commented out,
5843 because there is a problem in the pcode peep optimizer,
5844 * src/pic16/ralloc.c: the register allocator can now reuse local
5845 function symbols for another function. This saves register usage.
5846 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5848 Added file src/pic16/NOTES with information about program writing on
5849 the current port version.

5937 include information about variables allocated to the overlay
5940 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5942 * as/mcs51/lkmain.c: Help about -Y option

5954 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5956 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5957 (default behaviour).
5959 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5961 A python script to validate compiler diagnostic messages. It can be
5962 used to verify that sdcc complains about bad c source code and
5963 gives a good location of the error.
5964 * support/valdiag/Makefile,
5965 * support/valdiag/valdiag.py,
5966 * support/valdiag/tests/*

5983 Bug reported from Jesus Calvino-Fraga
5985 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5987 * sdcc.spec: updated
5988 * device/include/Makefile.in: don't install CVS directories
5989 * device/lib/Makefile.in: added removal of CVS directories after install
5990 * doc/Makefile: fixed install, added local_icons
5991 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5992 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5993 * src/ds390/gen.c (genRightShift): fixed bug #870788
5994 * src/SDCCast.c (decorateType): fixed bug #870781
5996 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5998 PIC16 port related changes:
5999 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6000 added variable stackPos,
6002 * gen.c: genCall, assignResultValue: added support for
6003 pushing/retrieving function parameters to/from stack,
6004 genFunction,genEndFunction: setup stack frame for the
6006 genAddrOf: will be changed according to bug 863624
6008 * added files genutils.c and genutils.h which contain gen*
6009 debugged and optimised functions extracted from gen.c
6011 * glue.c: added variable 'externs' which holds extern symbols,
6012 pic16emitRegularMap: is modified to properly handle relocatable
6013 symbols under the new scheme,
6014 pic16createInterruptVect: is modified
6015 pic16printPublics: is modified to emit 'global' assembler directives,
6016 added pic16_printExterns to print extern symbols,
6017 pic16glue: initializes stack/frame pointer in the beginning of
6018 the assembly output. Temporary hack, will be corrected later,
6019 because gplink yet does not support stack and SDCC does not
6020 yet support a type of crt0.o object to create the final binary.
6022 * Removed many lines that contain 8051 legacy code.
6023 * The code is finally placed under a 'code' directive.
6024 * Added port specific options.
6026 * _process_pragma: simplified since now we do not need *special*
6027 include file to define SFR registers. But a separate header
6028 will be needed. This will be developed later.
6029 * _pic16_parseOptions: added, parses port specific options:
6030 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6031 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6032 --preplace-udata-with=
6034 * _pic16_setDefaultOptions: modified to initialize section names,
6035 but hack is temporarly out of order since it needs improvement.
6036 * _pic16_genAssemblerPreamble: configuration words are emitted by
6037 their address instead of their name. This part is incomplete and
6038 supports only the 18Fxx2 devices. Other devices will emit an error
6039 during assembly since they do not contain the same set of config
6041 * _pic16_genIVT: is modified,
6043 * pcode.c: added definitions for some hardware registers that are needed
6045 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6046 All PCI entries are updated. Now LFSR is supported.
6047 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6048 * added pic16_newpCodeOpLit2 to support instructions with
6049 two literal arguments
6050 * pic16_pCode2str: corrected code that emits assembler instructions
6051 with two literal operands and those that have an access bit modifier
6052 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6053 this fixes a bug which caused some labels to be lost, when an
6054 assembler directive was added, i.e. banksel,
6055 * pic16_FixRegisterBanking: improved logic that causes the insertion
6057 * InlineFunction: functions that are called once, are not any more
6058 inlined. This can be a port option in the future,
6060 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6062 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6063 hold the corresponding uninitialized symbols,
6064 * pic16_allocProcessorRegister: registers have explicit marked the
6066 * pic16_allocInternalRegister: registers are explicit marked as
6068 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6069 processing list, so bit registers were lost,
6072 * ralloc.h: added field 'accessBank' and original symbol operand
6073 in register definition,
6074 * removed the field isMapped from register definition,
6076 ** Several functions have been removed from various sources:
6077 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6078 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6079 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6080 pic16_assignRelocatableRegisters
6082 ** others have been introduced:
6083 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6084 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6086 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6088 * support/scripts/inc2h.pl: changed definition of BIT_AT
6089 to emit 'sbit at' instead of 'bit at'. This was a request.
6091 PIC16 port related preliminary changes:
6092 * gen.c: prefixed function popRegFromString with
6093 pic16_ and all references to it corrected
6094 * pcode.c: all pic16_pc_* hardware registers prefixed
6095 with underscore (_),
6096 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6097 * ralloc.c: newReg(): when register is REG_SFR then
6098 set address to rIdx,
6099 pic16_allocProcessorRegister(): marks register wasUsed=0
6100 pic16_writeUsedRegs(): added a call to assign processor
6101 registers via pic16_assignFixedRegisters
6103 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6105 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6106 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6107 variables in unused register banks. Also the SSEG is placed
6108 wherever there is enough space for it, and IDATA can be anywhere
6109 in internal RAM. For now compile using -Wl-Y[stack_size].
6110 The mem file is different for this option as well, since it
6111 makes no sense of talking about DSEG lenght.
6113 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6115 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6116 in certain cases, e.g. when ROM assignment, patch provided
6117 from Albert den Haan.
6119 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6672 not occur if the control variable is involved with a
6673 relational operator.

7166 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7168 Try to make the peephole optimizer smarter by maintaining
7169 an association between the assembly source code and the
7170 iCodes that originated them. Put this information to use
7171 with a new peephole rule condition "notVolatile" so that
7172 the rules can be aggressive yet still safe.

7185 if the left or right operand symbols have the accuse flag set.
7187 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7189 Changed the type of the result of the ! (NOT) operator to char;
7190 previously it returned the same type as the source. This allows
7191 us to eliminate all the genFloatNot functions (all of its target
7192 implementations were very buggy) since !float can use the same
7195 * src/SDCCicode.c (ast2iCode): ! returns char
7196 * src/mcs51/gen.c (genNot, genNotFloat),
7197 * src/ds390/gen.c (genNot, genNotFloat),

7204 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7205 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7206 during interrupts. Ensure WSAVE is located at a shared bank address.
7207 2. Fixed page selection in some places
7208 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7209 the registers name strings.
7210 4. Fixed "signed / unsigned compare" compiler warnings.
7211 5. The PIC port manages its own allocation of the general purpose
7212 registers, but makes no attempt to reuse them. As a result when
7213 compiling it soon runs out of general purpose registers. Some
7214 additional code was added to the files pcode.c and device.c to walk
7215 through the function call tree and rename the registers so that they
7225 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7232 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7234 Made bitfield a distinct type from bit so that bitfields
7235 convert as per ANSI C and bits retain their traditional
7236 boolean style behaviour. Implemented bitfield support in
7244 * src/ds390/gen.c: bit v bitfield split
7245 * src/z80/gen.c: New support for bitfields
7246 * support/regression/tests/bitfields.c: reenabled z80,
7249 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7251 Rules 246.x, 247.x relate to bitfields, the others speed up
7252 access to xdata mapped I/O devices.
7254 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7256 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7258 Cleaned up genPackBits and genUnpackBits and added two helper
7259 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7260 for literal assignments in genPackBits (thanks to Frieder for
7266 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7268 Fixed bug #748310 (pointer to function type mishandled when the
7269 function name is omitted). Also fixed a SIGSEGV when a function
7270 attribute (reentrant, etc) is used on a non-function or on a
7271 function but misplaced before the parameter list.

7298 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7300 Made the constant following the "interrupt" keyword optional. If
7301 omitted, the function will not automatically be given an entry
7302 in the interrupt vector table (similar to #pragma NOIV, but
7303 less syntacticly kludgy). The interrupt number is also now
7304 range checked. Also fixed a bug in the high order bit example

7780 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7781 the regression tests I'm not brave enough to enable 245.b, 245.c
7782 * doc/sdccman.lyx: added latex preamble for hyperref package.
7783 Using pdflatex this will give you a hyperlinked pdf file with
7784 bookmarks. (prepend '%' before /usepackage if this breaks something)

7825 it can be defined with CFLAGS when running configure
7826 * src/SDCCmain.c: fixed compiling + linking with object files
7828 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7830 * configure.in: configure for pic16 port,
7831 added --disable-pic16-port
7832 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7833 * src/SDCCmain.c: linkOptions is changed to set *,
7834 added if/endif conditional macros to remove options help
7835 messages from optionsTable when a port is not configured, added
7836 support for the PIc16 port in the ports table, when executing
7837 the compiler with no port specified on command line, a default
7838 port is selected with the new macro DEFAULT_PORT which is
7839 defined in port.h, in setDefaultOptions() linkOptions is removed
7840 from initialization assignment, since now it is a set,
7841 parseCmdLine uses setParseWithComma for linkOptions, in
7842 linkEdit() linkOptions are accessed with new function indexSet()
7843 which returns the i'th item of a set variable. See SDCCset.c, in
7844 linkEdit() when calling buildCmdLine(), added linkOptions as
7845 last argument. Now users can pass arguments to gplink via the
7846 -Wl option, main() uses pic16glue() to glue up pic16 programs

7858 * src/pic16/glue.c: commented out some error producing lines
7859 * src/pic16/main.c: __config directives are commented out to stop
7860 gpasm complaining and test the linkage with gplink, _linkCmd and
7861 _asmCmd changed to be more gplink and gpasm friendly
7862 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7863 produced an error when parsed, peep rule 12 is added to utilize
7864 movff, but it is commented out since the pCode does not support
7865 yet a command with 2 address arguments
7867 2003-05-18 <johan AT balder>
7869 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7894 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7896 2003-05-11 Borut Razem <borut.razem AT siol.net>
7898 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7899 the path of bin directory, so that PATH is the only env. variable, which has to be set
7900 in case of standard installation.
7901 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8904 * src/SDCCicode.c: fixed array add
8906 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8907 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8908 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8910 2003-01-04 <johan AT balder>
8912 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8914 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8915 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

8927 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8928 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8930 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8932 * in \sdcc\as\mcs51\ changed these files in order to create an
8933 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8934 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8935 following files to include the previous two files: aslink.dsp,
8936 Makefile.aslink, Makefile.bcc, and Makefile.in.
8938 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8939 .adb instead of .cdb
8941 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8943 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8944 value from option --iram-size.
8946 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8948 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8951 2002-09-18 <wiml AT hhhh.org>
8953 * SDCClrange.h: exposed setFromRange() and setToRange()
8954 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8955 packRegsForAccUse() (bug 542397)
8956 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8957 multiple times and emitting the fetch operations more than once
8958 added aopGetUsesAcc() function to allow binary operators to
8959 fetch their operands in the correct order; made genMinus() emit
8960 compact code for X = LITERAL - Y
8962 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8963 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8964 sprintf() in line 1267.
8966 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8967 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8970 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8971 Changes to aslink (All the changes are marked with 'JCF'):
8973 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8976 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8977 area BSEG. Also moves, if possible, the DATA area down into the internal
8978 ram so more space is available.
8980 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8983 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8984 not bytes. Function summary() which creates a memory usage summary
8985 file with extension .mem. Reports of overlaping stack and small stack
8986 size. If the space for the stack is less than 16 bytes aslink trows a
8989 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8990 the 8051. Option 'y' for memory summary output file.
8992 Changes to sdcc (All the changes are marked with 'JCF'):
8994 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8996 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8997 overlaying area for it (uses RegBankUsed[4]).
8999 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9000 bank zero as used by default. By default aslink locates the stack
9001 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9002 the creation of the .mem file. Delegates the allocation of data area
9003 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9004 the begining of the stack area to aslink.
9006 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9007 glue() in SDCCglue.c creates an area for it.
9009 2002-09-03 Borut Razem <borut.razem AT siol.net>
9010 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9011 sdcc/src/pic/glue.c:
9012 introduced atexit() handler for teporay files removal in case of
9013 errors, assertions, ...
9015 2002-08-29 Borut Razem <borut.razem AT siol.net>
9016 * sdcc/support/cpp2/auto-host_vc_in.h:
9017 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9018 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9019 Maybe there is a similar problem with BORLANDC? It should be checked!
9021 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9022 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9023 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9024 was not executed, and the compiler (cl) launched a warning:
9025 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9027 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9028 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9030 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9031 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9033 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9034 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

9038 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9039 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9040 - added Release configuration in VS projects
9041 - review of compiler an linker options
9042 - VC .exe files are generated in bin_vc directory, not to interfere
9043 with binaries generated from other projects (cygwin, mingw, bcc ...)
9045 * sdcc/src/yacc.dsp: added
9047 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9048 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9049 and insert the version number definitions from .version
9051 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9053 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9054 added - genarate auto-host.h using auto-host_vc_in.h as template
9057 removed from CVS, generated automatically
9059 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9060 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9062 2002-08-11 Borut Razem <borut.razem AT siol.net>
9063 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9065 2002-08-10 Borut Razem <borut.razem AT siol.net>
9066 * src/SDCCmain.c (main):
9067 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9068 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9069 The consequence was that some temporary files were not removed.
9072 unification of code in functions tempfilename() and tempfile():
9073 function tempnam() is defined in Visual Studio 6.0 and .NET
9075 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9077 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9078 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9079 - removed compiler command line option /WX: Treats all warnings as errors
9080 - update a list of source files, included into the project
9082 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9280 * sdcc/src/SDCCloop.c:
9281 Previous fix was not good. basic blocks that have "break" or "return" are
9282 not really partof a loop , but live ranges used in these blocks should
9283 be live thru the entire loop, so set partOfLoop but don't add them to
