1731 if condition == CARRY)
1732 * (genCmp): adapted to new genSkipc semantics
1733 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
1734 on rIfx (genCmp was broken)
1736 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1738 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1739 * src/z80/main.c (_keywords[]),
1740 * src/SDCCglobal.h (struct options),
1742 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1743 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1744 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1745 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1746 always available in leading double underscore form. The C99 support is
1747 mostly missing, but it's a start.
1748 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1749 reserved identifier "__data".
1751 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1761 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
1764 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1766 * src/port.h (struct PORT),

1795 immedDom() returning wrong block; probably fixes bug #1160833)
1797 2005-03-20 Borut Razem <borut.razem AT siol.net>
1799 * support/scripts/inc2h.pl: WIN32 port
1801 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1803 * device/lib/makefile.in: added abs.c and labs.c
1805 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1807 * device/include/stdint.h: added
1808 * device/lib/abs.c: added
1809 * device/lib/labs.c: added
1810 * device/include/stdlib.h: added abs() and labs() prototypes

1827 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1829 * device/lib/printf_large.c: removed inline assembly for portability and
1830 readability. Use printf_fast if speed or size are more important.
1831 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1832 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1834 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1836 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1837 prevent compiler warning
1839 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1841 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1842 moved to level 0 and declared as static. Also they are explicit
1843 placed in access bank. This was necessery because some times they
1844 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1845 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1846 optimizations. Currently only compare to unsigned char is implemented,
1847 * src/pic16/gen.c: added fReturnIdx array,
1848 * (struct resolvedIfx) is moved to gen.h and made public,
1849 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1850 * (aopForSym): added an optimization to directly store in stack of
1851 the operand of a SEND iCode,
1852 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1853 but as registers instead (AOP_REG) using the fReturnIdx array,
1854 * (pic16_freeAsmop): remove the freed register from the
1855 _G.sregsAlloc field,
1856 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1857 a compare of 'WREG',
1858 * (pic16_popGetTempRegCond): changed function prototype, now
1859 function takes also a bitVector argument v which holds the current
1860 set of registers that are allocated for stack access by aopForSym,
1861 registers allocated in aopForSym for accessing stack symbols are not
1862 any more part of the functions usedRegs field,
1863 * (genCall): some times aopOp is called for a stack variable to be
1864 send, aopForSym might perform the push, if this is true make sure
1865 that genCall doesn't push the variable twice by testing _G.resDirect,
1866 * (genFunction): changed testing for unspecified interrupt number
1867 from 256 to INTNO_UNSPEC,
1868 * modified selection scheme of frame pointer generation. Previously
1869 if function did use local registers a frame pointer was generated,
1870 now a frame pointer is generated only if function has arguments
1871 (that need PLUSW2 register access), or has stack arguments, or the
1872 compiler is not instructed to omit the frame pointer,
1873 * (genEndFunction): before restoring local registers that were saved
1874 in the function preamble, also restore the registers that *might*
1875 have been allocated for stack access,
1876 * (genRet): removed some old comments,
1877 * (genCmp, the active (RN's) version): added a call to the
1878 pic16_genCmp_special function to perform the compare with a more
1879 robust and optimized way,
1880 * (genInline): a feature has been added in inline code generation,
1881 which allows a wildcard variable substitution when writing inline
1882 assembly. Code is incomplete and experimental therefore undocumented,
1883 * (genCast): changed order of aopOp for result and right to allow
1884 aopForSym to directly load the result if possible,
1885 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1886 perform an optimized compare on some selected special occasions,
1887 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1888 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1889 generate an IVT any more,
1890 * src/pic16/main.c (pic16_optionsTable): added command line option
1892 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1893 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1895 * src/pic16/NOTES: Raphael Neider added in list of active developers
1896 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1897 jumptable_end to prevent bug #,
1898 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1899 inCond and outCond fields,
1900 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1901 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1902 turn off register spilling,
1903 * (packRegsForOneUse): synced with other ports' versions although it
1904 is not used currently,
1905 * (pic16_packRegisters): added an optimization while reading
1906 structure bitfields, some registers may be saved (malloc code is
1907 decreased by 80 bytes)
1909 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1911 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1912 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1913 this can be optimized more?
1915 2005-03-10 Raphael Neider <rneider AT web.de>
1917 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1918 genNearPointerGet): (hopefully) fixed access to bitfields via
1919 pointers (p->bitN = x; and x = p->bitN; failed)
1921 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2108 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2109 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2110 this might fix SIGSEGVs on MinGW...
2111 * src/SDCCopt.c (killDeadCode): restored original behaviour
2112 (volatile operands might get thrown away though)
2114 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2591 * added libc directory. The current version of LibC contains string
2592 functions, ctype functions and macros and some functions of the
2593 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2594 be extensively tested in the future. Standard disclaimer here.
2595 Library is not automatically build yet. But one can build it by
2596 invoking 'make' inside the libc directory.
2597 * added ADC library under libio. Preliminary version yet.
2599 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2607 * (pic16_storeForReturn): optimized return of 0,
2608 * (genCmp): experimental code for new genCmp which uses PIC18's
2609 special compare&skip instructions. Initial tests fail some times
2610 with variables grater than 1 byte in size, so new code is disabled,
2611 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2613 * (genCast): began a fix to optimize the casting of a bit to another
2614 bit, now assigning a bitfield to another bitfield will fail, sorry,
2615 * src/pic16/main.c: disabled the use of lr-support feature,
2616 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2617 * added some function prototypes, added function _debugf prototype,

2619 bits with offset (case PO_GPR_BIT),
2620 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2622 * (isBankInstruction): modified to return 0 for no banking instruction,
2623 and 1 for banking instruction,
2624 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2625 caused stop processing pCodes after a inline assembly block,
2626 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2627 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2628 registers when it shouldn't,
2629 * src/pic16/ralloc.c (allocReg): add preliminary support for
2630 supporting a limited set of temporary registers,
2632 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5637 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5639 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5640 loaded with the linker search paths (-L arguments) and the libraries
5641 to be linked with the current source (-l arguments). Changes
5642 currently will affect only the pic16 port.
5643 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5644 include path the port specific paths and port specific libraries,
5645 * gplink command now contains the $3 argument,
5646 * src/pic16/device.h,
5647 * src/pic16/device.c,: structure PIC_device is made public and
5648 renamed to PIC16_device, the same for variable Pics which is renamed

5663 Documenting changes from previous commits.
5664 * configure.in (version 1.56),
5665 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5666 when generating output files to configure the pic16 library,
5667 but now I've commented it out, since gputils aren't installed in the
5668 SF compile farm, so library won't compile
5670 * device/lib/Makefile.in (version 1.56): initially I've added in
5671 target 'all' the prerequestive 'model-pic16' so it compiled the
5672 pic16 library, but now I've commented it out for the same reasons
5674 * added targets 'model-pic16' and 'objects-pic16' to compile the
5676 * added target 'port-specific-objects-pic16' to handle the
5677 generated libraries and copy them into the build/ directory
5678 * added target 'clean-intermediate-pic16' to clean intermediate
5679 files into pic16 directory
5680 * in target 'installdirs' added line to create directory pic16 in
5681 the installation path
5683 * device/include/Makefile.in (version 1.11): in target 'install'
5684 added lines to copy all header files to installation path,

5731 via literal number. The symbol is placed in the corresponding
5732 position of the data ram
5733 * (pic16_dump_section): relocatable and absolute uninitialized
5734 data are now emitted in sorted order to reduce section naming,
5735 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5736 weren't marked as being in the access bank,
5738 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5740 Added portion of GNU PIC Library under the directory
5741 device/include/pic16 and device/lib/pic16. These files
5742 contain the declarations of SFRs for the PIC18Fxx2 devices.

5773 all over. Telling LaTeX to be less strict with word spacing
5774 to better keep the right margin. Changed some notes about
5775 maintainance of the ports in section 3.2.1 - is it OK like this?
5777 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5817 * src/pic16/peeph.def: all peepholes with movff are commented out,
5818 because there is a problem in the pcode peep optimizer,
5819 * src/pic16/ralloc.c: the register allocator can now reuse local

5912 include information about variables allocated to the overlay
5915 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5917 * as/mcs51/lkmain.c: Help about -Y option

5927 LEFT_OP (left shift)
5929 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5931 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5932 (default behaviour).
5934 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5936 A python script to validate compiler diagnostic messages. It can be
5937 used to verify that sdcc complains about bad c source code and
5938 gives a good location of the error.
5939 * support/valdiag/Makefile,
5940 * support/valdiag/valdiag.py,
5941 * support/valdiag/tests/*
5943 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5945 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5956 * src/common.h: added ifndef/define/endif macros
5957 around the header file.
5958 Bug reported from Jesus Calvino-Fraga
5960 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5962 * sdcc.spec: updated
5963 * device/include/Makefile.in: don't install CVS directories
5964 * device/lib/Makefile.in: added removal of CVS directories after install
5965 * doc/Makefile: fixed install, added local_icons
5966 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5967 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5968 * src/ds390/gen.c (genRightShift): fixed bug #870788
5969 * src/SDCCast.c (decorateType): fixed bug #870781
5971 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5973 PIC16 port related changes:
5974 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5975 added variable stackPos,
5977 * gen.c: genCall, assignResultValue: added support for
5978 pushing/retrieving function parameters to/from stack,
5979 genFunction,genEndFunction: setup stack frame for the
5981 genAddrOf: will be changed according to bug 863624
5983 * added files genutils.c and genutils.h which contain gen*
5984 debugged and optimised functions extracted from gen.c
5986 * glue.c: added variable 'externs' which holds extern symbols,
5987 pic16emitRegularMap: is modified to properly handle relocatable
5988 symbols under the new scheme,
5989 pic16createInterruptVect: is modified
5990 pic16printPublics: is modified to emit 'global' assembler directives,
5991 added pic16_printExterns to print extern symbols,
5992 pic16glue: initializes stack/frame pointer in the beginning of
5993 the assembly output. Temporary hack, will be corrected later,
5994 because gplink yet does not support stack and SDCC does not
5995 yet support a type of crt0.o object to create the final binary.
5997 * Removed many lines that contain 8051 legacy code.
5998 * The code is finally placed under a 'code' directive.
5999 * Added port specific options.
6001 * _process_pragma: simplified since now we do not need *special*
6002 include file to define SFR registers. But a separate header
6003 will be needed. This will be developed later.
6004 * _pic16_parseOptions: added, parses port specific options:
6005 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6006 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6007 --preplace-udata-with=
6009 * _pic16_setDefaultOptions: modified to initialize section names,
6010 but hack is temporarly out of order since it needs improvement.
6011 * _pic16_genAssemblerPreamble: configuration words are emitted by
6012 their address instead of their name. This part is incomplete and
6013 supports only the 18Fxx2 devices. Other devices will emit an error
6014 during assembly since they do not contain the same set of config
6016 * _pic16_genIVT: is modified,
6018 * pcode.c: added definitions for some hardware registers that are needed
6020 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6021 All PCI entries are updated. Now LFSR is supported.
6022 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6023 * added pic16_newpCodeOpLit2 to support instructions with
6024 two literal arguments
6025 * pic16_pCode2str: corrected code that emits assembler instructions
6026 with two literal operands and those that have an access bit modifier
6027 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6028 this fixes a bug which caused some labels to be lost, when an
6029 assembler directive was added, i.e. banksel,
6030 * pic16_FixRegisterBanking: improved logic that causes the insertion
6032 * InlineFunction: functions that are called once, are not any more
6033 inlined. This can be a port option in the future,
6035 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6037 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6038 hold the corresponding uninitialized symbols,
6039 * pic16_allocProcessorRegister: registers have explicit marked the
6041 * pic16_allocInternalRegister: registers are explicit marked as
6043 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6044 processing list, so bit registers were lost,
6047 * ralloc.h: added field 'accessBank' and original symbol operand
6048 in register definition,
6049 * removed the field isMapped from register definition,
6051 ** Several functions have been removed from various sources:
6052 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6053 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6054 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6055 pic16_assignRelocatableRegisters
6057 ** others have been introduced:
6058 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6059 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6061 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6063 * support/scripts/inc2h.pl: changed definition of BIT_AT
6064 to emit 'sbit at' instead of 'bit at'. This was a request.
6066 PIC16 port related preliminary changes:
6067 * gen.c: prefixed function popRegFromString with
6068 pic16_ and all references to it corrected
6069 * pcode.c: all pic16_pc_* hardware registers prefixed
6070 with underscore (_),
6071 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6072 * ralloc.c: newReg(): when register is REG_SFR then
6073 set address to rIdx,
6074 pic16_allocProcessorRegister(): marks register wasUsed=0
6075 pic16_writeUsedRegs(): added a call to assign processor
6076 registers via pic16_assignFixedRegisters
6078 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6080 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6081 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6082 variables in unused register banks. Also the SSEG is placed
6083 wherever there is enough space for it, and IDATA can be anywhere
6084 in internal RAM. For now compile using -Wl-Y[stack_size].
6085 The mem file is different for this option as well, since it
6086 makes no sense of talking about DSEG lenght.
6088 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6090 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6091 in certain cases, e.g. when ROM assignment, patch provided
6092 from Albert den Haan.
6094 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7117 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7118 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7137 A few small changes that speed up the peephole optimizer.
7141 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7143 Try to make the peephole optimizer smarter by maintaining
7144 an association between the assembly source code and the
7145 iCodes that originated them. Put this information to use
7146 with a new peephole rule condition "notVolatile" so that
7147 the rules can be aggressive yet still safe.
7152 * src/mcs51/peeph.def
7154 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7158 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

7162 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7164 Changed the type of the result of the ! (NOT) operator to char;
7165 previously it returned the same type as the source. This allows
7166 us to eliminate all the genFloatNot functions (all of its target
7167 implementations were very buggy) since !float can use the same
7170 * src/SDCCicode.c (ast2iCode): ! returns char

7182 2. Fixed page selection in some places
7183 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7184 the registers name strings.
7185 4. Fixed "signed / unsigned compare" compiler warnings.
7186 5. The PIC port manages its own allocation of the general purpose
7187 registers, but makes no attempt to reuse them. As a result when
7188 compiling it soon runs out of general purpose registers. Some
7189 additional code was added to the files pcode.c and device.c to walk
7190 through the function call tree and rename the registers so that they
7200 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7207 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7209 Made bitfield a distinct type from bit so that bitfields
7210 convert as per ANSI C and bits retain their traditional
7211 boolean style behaviour. Implemented bitfield support in
7219 * src/ds390/gen.c: bit v bitfield split
7220 * src/z80/gen.c: New support for bitfields
7221 * support/regression/tests/bitfields.c: reenabled z80,
7224 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7226 Rules 246.x, 247.x relate to bitfields, the others speed up
7227 access to xdata mapped I/O devices.
7229 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7231 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7233 Cleaned up genPackBits and genUnpackBits and added two helper
7234 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7235 for literal assignments in genPackBits (thanks to Frieder for
7241 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7243 Fixed bug #748310 (pointer to function type mishandled when the
7244 function name is omitted). Also fixed a SIGSEGV when a function
7245 attribute (reentrant, etc) is used on a non-function or on a
7246 function but misplaced before the parameter list.

7273 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7275 Made the constant following the "interrupt" keyword optional. If
7276 omitted, the function will not automatically be given an entry
7277 in the interrupt vector table (similar to #pragma NOIV, but
7278 less syntacticly kludgy). The interrupt number is also now
7279 range checked. Also fixed a bug in the high order bit example

7782 * src/pic16/pcode.c: Cleaned warnings
7783 * src/pic16/pcodeflow.c: Cleaned warnings
7784 * src/pic16/pcoderegs.c: Cleaned warnings

7800 it can be defined with CFLAGS when running configure
7801 * src/SDCCmain.c: fixed compiling + linking with object files
7803 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7806 added --disable-pic16-port
7807 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7808 * src/SDCCmain.c: linkOptions is changed to set *,
7809 added if/endif conditional macros to remove options help
7810 messages from optionsTable when a port is not configured, added
7811 support for the PIc16 port in the ports table, when executing
7812 the compiler with no port specified on command line, a default
7813 port is selected with the new macro DEFAULT_PORT which is
7814 defined in port.h, in setDefaultOptions() linkOptions is removed
7815 from initialization assignment, since now it is a set,
7816 parseCmdLine uses setParseWithComma for linkOptions, in
7817 linkEdit() linkOptions are accessed with new function indexSet()
7818 which returns the i'th item of a set variable. See SDCCset.c, in
7819 linkEdit() when calling buildCmdLine(), added linkOptions as
7820 last argument. Now users can pass arguments to gplink via the
7821 -Wl option, main() uses pic16glue() to glue up pic16 programs

7833 * src/pic16/glue.c: commented out some error producing lines
7834 * src/pic16/main.c: __config directives are commented out to stop
7835 gpasm complaining and test the linkage with gplink, _linkCmd and
7836 _asmCmd changed to be more gplink and gpasm friendly
7837 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7838 produced an error when parsed, peep rule 12 is added to utilize
7839 movff, but it is commented out since the pCode does not support
7840 yet a command with 2 address arguments
7842 2003-05-18 <johan AT balder>
7844 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7871 2003-05-11 Borut Razem <borut.razem AT siol.net>
7873 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7874 the path of bin directory, so that PATH is the only env. variable, which has to be set

8879 * src/SDCCicode.c: fixed array add
8881 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8882 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8883 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8885 2003-01-04 <johan AT balder>
8887 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8889 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8890 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8892 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8902 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8903 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8905 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8907 * in \sdcc\as\mcs51\ changed these files in order to create an
8908 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8909 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8910 following files to include the previous two files: aslink.dsp,
8911 Makefile.aslink, Makefile.bcc, and Makefile.in.
8913 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8914 .adb instead of .cdb
8916 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8918 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8919 value from option --iram-size.
8921 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8923 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8926 2002-09-18 <wiml AT hhhh.org>
8928 * SDCClrange.h: exposed setFromRange() and setToRange()
8929 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8930 packRegsForAccUse() (bug 542397)
8931 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8932 multiple times and emitting the fetch operations more than once
8933 added aopGetUsesAcc() function to allow binary operators to
8934 fetch their operands in the correct order; made genMinus() emit
8935 compact code for X = LITERAL - Y
8937 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8938 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8939 sprintf() in line 1267.
8941 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8942 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8945 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8946 Changes to aslink (All the changes are marked with 'JCF'):
8948 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8951 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8952 area BSEG. Also moves, if possible, the DATA area down into the internal
8953 ram so more space is available.
8955 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8958 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8959 not bytes. Function summary() which creates a memory usage summary
8960 file with extension .mem. Reports of overlaping stack and small stack
8961 size. If the space for the stack is less than 16 bytes aslink trows a
8964 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8965 the 8051. Option 'y' for memory summary output file.
8967 Changes to sdcc (All the changes are marked with 'JCF'):
8969 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8971 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8972 overlaying area for it (uses RegBankUsed[4]).
8974 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8975 bank zero as used by default. By default aslink locates the stack
8976 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8977 the creation of the .mem file. Delegates the allocation of data area
8978 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8979 the begining of the stack area to aslink.
8981 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8982 glue() in SDCCglue.c creates an area for it.
8984 2002-09-03 Borut Razem <borut.razem AT siol.net>
8985 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8986 sdcc/src/pic/glue.c:
8987 introduced atexit() handler for teporay files removal in case of
8988 errors, assertions, ...
8990 2002-08-29 Borut Razem <borut.razem AT siol.net>
8991 * sdcc/support/cpp2/auto-host_vc_in.h:
8992 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8993 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8994 Maybe there is a similar problem with BORLANDC? It should be checked!
8996 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8997 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8998 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8999 was not executed, and the compiler (cl) launched a warning:
9000 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9002 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9003 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9005 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9006 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9008 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9009 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9010 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9011 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9012 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9013 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9014 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9015 - added Release configuration in VS projects
9016 - review of compiler an linker options
9017 - VC .exe files are generated in bin_vc directory, not to interfere
9018 with binaries generated from other projects (cygwin, mingw, bcc ...)
9020 * sdcc/src/yacc.dsp: added
9022 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9023 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9024 and insert the version number definitions from .version
9026 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9028 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9029 added - genarate auto-host.h using auto-host_vc_in.h as template
9032 removed from CVS, generated automatically
9034 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9035 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9037 2002-08-11 Borut Razem <borut.razem AT siol.net>
9038 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9040 2002-08-10 Borut Razem <borut.razem AT siol.net>
9041 * src/SDCCmain.c (main):
9042 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9043 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9044 The consequence was that some temporary files were not removed.
9047 unification of code in functions tempfilename() and tempfile():
9048 function tempnam() is defined in Visual Studio 6.0 and .NET
9050 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9052 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9053 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9054 - removed compiler command line option /WX: Treats all warnings as errors
9055 - update a list of source files, included into the project
9057 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9058 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9059 changed project type to Generic Project so that can be correcly converted to VS.NET project
9061 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9063 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9065 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9067 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9068 added return 0 statements after assert() to make compiler happy
9070 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9071 added newline in the def file to keep MSC compiler satisfied
9073 * sdcc/src/z80/gen.c:
9074 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9075 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
