1708 2005-03-26 Raphael Neider <rneider AT web.de>
1710 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
1711 if condition == CARRY)
1712 * (genCmp): adapted to new genSkipc semantics
1713 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
1714 on rIfx (genCmp was broken)
1716 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1718 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1719 * src/z80/main.c (_keywords[]),
1720 * src/SDCCglobal.h (struct options),
1722 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1723 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1724 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1725 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1726 always available in leading double underscore form. The C99 support is
1727 mostly missing, but it's a start.
1728 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1729 reserved identifier "__data".
1731 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1733 * src/mcs51/peeph.def: fixed bug 1170013

1741 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
1744 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1746 * src/port.h (struct PORT),
1747 * src/avr/ralloc.c (avr_assignRegisters),
1749 * src/ds390/ralloc.c (ds390_assignRegisters),
1751 * src/hc08/ralloc.c (hc08_assignRegisters),

1773 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1774 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1775 immedDom() returning wrong block; probably fixes bug #1160833)
1777 2005-03-20 Borut Razem <borut.razem AT siol.net>
1779 * support/scripts/inc2h.pl: WIN32 port
1781 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1783 * device/lib/makefile.in: added abs.c and labs.c
1785 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1787 * device/include/stdint.h: added
1788 * device/lib/abs.c: added
1789 * device/lib/labs.c: added
1790 * device/include/stdlib.h: added abs() and labs() prototypes

1805 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1807 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1809 * device/lib/printf_large.c: removed inline assembly for portability and
1810 readability. Use printf_fast if speed or size are more important.
1811 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1812 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1814 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1816 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1817 prevent compiler warning
1819 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1821 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1822 moved to level 0 and declared as static. Also they are explicit
1823 placed in access bank. This was necessery because some times they
1824 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1825 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1826 optimizations. Currently only compare to unsigned char is implemented,
1827 * src/pic16/gen.c: added fReturnIdx array,
1828 * (struct resolvedIfx) is moved to gen.h and made public,
1829 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1830 * (aopForSym): added an optimization to directly store in stack of
1831 the operand of a SEND iCode,
1832 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1833 but as registers instead (AOP_REG) using the fReturnIdx array,
1834 * (pic16_freeAsmop): remove the freed register from the
1835 _G.sregsAlloc field,
1836 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1837 a compare of 'WREG',
1838 * (pic16_popGetTempRegCond): changed function prototype, now
1839 function takes also a bitVector argument v which holds the current
1840 set of registers that are allocated for stack access by aopForSym,
1841 registers allocated in aopForSym for accessing stack symbols are not
1842 any more part of the functions usedRegs field,
1843 * (genCall): some times aopOp is called for a stack variable to be
1844 send, aopForSym might perform the push, if this is true make sure
1845 that genCall doesn't push the variable twice by testing _G.resDirect,
1846 * (genFunction): changed testing for unspecified interrupt number
1847 from 256 to INTNO_UNSPEC,
1848 * modified selection scheme of frame pointer generation. Previously
1849 if function did use local registers a frame pointer was generated,
1850 now a frame pointer is generated only if function has arguments
1851 (that need PLUSW2 register access), or has stack arguments, or the
1852 compiler is not instructed to omit the frame pointer,
1853 * (genEndFunction): before restoring local registers that were saved
1854 in the function preamble, also restore the registers that *might*
1855 have been allocated for stack access,
1856 * (genRet): removed some old comments,
1857 * (genCmp, the active (RN's) version): added a call to the
1858 pic16_genCmp_special function to perform the compare with a more
1859 robust and optimized way,
1860 * (genInline): a feature has been added in inline code generation,
1861 which allows a wildcard variable substitution when writing inline
1862 assembly. Code is incomplete and experimental therefore undocumented,
1863 * (genCast): changed order of aopOp for result and right to allow
1864 aopForSym to directly load the result if possible,
1865 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1866 perform an optimized compare on some selected special occasions,
1867 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1868 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1869 generate an IVT any more,
1870 * src/pic16/main.c (pic16_optionsTable): added command line option
1872 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1873 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1875 * src/pic16/NOTES: Raphael Neider added in list of active developers
1876 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1877 jumptable_end to prevent bug #,
1878 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1879 inCond and outCond fields,
1880 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1881 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1882 turn off register spilling,
1883 * (packRegsForOneUse): synced with other ports' versions although it
1884 is not used currently,
1885 * (pic16_packRegisters): added an optimization while reading
1886 structure bitfields, some registers may be saved (malloc code is
1887 decreased by 80 bytes)
1889 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1891 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1892 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1893 this can be optimized more?
1895 2005-03-10 Raphael Neider <rneider AT web.de>
1897 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1898 genNearPointerGet): (hopefully) fixed access to bitfields via
1899 pointers (p->bitN = x; and x = p->bitN; failed)

2088 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2089 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2090 this might fix SIGSEGVs on MinGW...
2091 * src/SDCCopt.c (killDeadCode): restored original behaviour
2092 (volatile operands might get thrown away though)
2094 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2534 generated for switch statements. For now you need to set the
2535 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2536 Now 4 algorithms for mcs51 jumptable generation are used:
2537 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2538 addresses loaded pc-relative for up to 112 cases and stack-pushing
2539 target addresses loaded with offset from dptr for up to 256 cases.

5617 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5619 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5620 loaded with the linker search paths (-L arguments) and the libraries
5621 to be linked with the current source (-l arguments). Changes
5622 currently will affect only the pic16 port.
5623 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5624 include path the port specific paths and port specific libraries,
5625 * gplink command now contains the $3 argument,
5626 * src/pic16/device.h,
5627 * src/pic16/device.c,: structure PIC_device is made public and
5628 renamed to PIC16_device, the same for variable Pics which is renamed

5643 Documenting changes from previous commits.
5644 * configure.in (version 1.56),
5645 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5646 when generating output files to configure the pic16 library,
5647 but now I've commented it out, since gputils aren't installed in the
5648 SF compile farm, so library won't compile
5650 * device/lib/Makefile.in (version 1.56): initially I've added in
5651 target 'all' the prerequestive 'model-pic16' so it compiled the
5652 pic16 library, but now I've commented it out for the same reasons
5654 * added targets 'model-pic16' and 'objects-pic16' to compile the
5656 * added target 'port-specific-objects-pic16' to handle the
5657 generated libraries and copy them into the build/ directory
5658 * added target 'clean-intermediate-pic16' to clean intermediate
5659 files into pic16 directory
5660 * in target 'installdirs' added line to create directory pic16 in
5661 the installation path
5663 * device/include/Makefile.in (version 1.11): in target 'install'
5664 added lines to copy all header files to installation path,
5665 * in target 'installdirs' added line create directory for pic16
5666 headers in the installation path

5681 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5682 option so that it actually works. Made it specific to the z80, since
5683 the gbz80 doesn't have these kinds of I/O ports.
5685 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5711 via literal number. The symbol is placed in the corresponding
5712 position of the data ram
5713 * (pic16_dump_section): relocatable and absolute uninitialized
5714 data are now emitted in sorted order to reduce section naming,
5715 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5716 weren't marked as being in the access bank,
5718 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5720 Added portion of GNU PIC Library under the directory
5721 device/include/pic16 and device/lib/pic16. These files
5722 contain the declarations of SFRs for the PIC18Fxx2 devices.

5753 all over. Telling LaTeX to be less strict with word spacing
5754 to better keep the right margin. Changed some notes about
5755 maintainance of the ports in section 3.2.1 - is it OK like this?
5757 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5797 * src/pic16/peeph.def: all peepholes with movff are commented out,
5798 because there is a problem in the pcode peep optimizer,
5799 * src/pic16/ralloc.c: the register allocator can now reuse local

5892 include information about variables allocated to the overlay
5895 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5897 * as/mcs51/lkmain.c: Help about -Y option

5909 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5911 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5912 (default behaviour).
5914 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5916 A python script to validate compiler diagnostic messages. It can be
5917 used to verify that sdcc complains about bad c source code and
5918 gives a good location of the error.
5919 * support/valdiag/Makefile,
5920 * support/valdiag/valdiag.py,
5921 * support/valdiag/tests/*
5923 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5936 * src/common.h: added ifndef/define/endif macros
5937 around the header file.
5938 Bug reported from Jesus Calvino-Fraga
5940 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5942 * sdcc.spec: updated
5943 * device/include/Makefile.in: don't install CVS directories
5944 * device/lib/Makefile.in: added removal of CVS directories after install
5945 * doc/Makefile: fixed install, added local_icons
5946 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5947 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5948 * src/ds390/gen.c (genRightShift): fixed bug #870788
5949 * src/SDCCast.c (decorateType): fixed bug #870781
5951 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5953 PIC16 port related changes:
5954 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5955 added variable stackPos,
5957 * gen.c: genCall, assignResultValue: added support for
5958 pushing/retrieving function parameters to/from stack,
5959 genFunction,genEndFunction: setup stack frame for the
5961 genAddrOf: will be changed according to bug 863624
5963 * added files genutils.c and genutils.h which contain gen*
5964 debugged and optimised functions extracted from gen.c
5966 * glue.c: added variable 'externs' which holds extern symbols,
5967 pic16emitRegularMap: is modified to properly handle relocatable
5968 symbols under the new scheme,
5969 pic16createInterruptVect: is modified
5970 pic16printPublics: is modified to emit 'global' assembler directives,
5971 added pic16_printExterns to print extern symbols,
5972 pic16glue: initializes stack/frame pointer in the beginning of
5973 the assembly output. Temporary hack, will be corrected later,
5974 because gplink yet does not support stack and SDCC does not
5975 yet support a type of crt0.o object to create the final binary.
5977 * Removed many lines that contain 8051 legacy code.
5978 * The code is finally placed under a 'code' directive.
5979 * Added port specific options.
5981 * _process_pragma: simplified since now we do not need *special*
5982 include file to define SFR registers. But a separate header
5983 will be needed. This will be developed later.
5984 * _pic16_parseOptions: added, parses port specific options:
5985 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5986 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5987 --preplace-udata-with=
5989 * _pic16_setDefaultOptions: modified to initialize section names,
5990 but hack is temporarly out of order since it needs improvement.
5991 * _pic16_genAssemblerPreamble: configuration words are emitted by
5992 their address instead of their name. This part is incomplete and
5993 supports only the 18Fxx2 devices. Other devices will emit an error
5994 during assembly since they do not contain the same set of config
5996 * _pic16_genIVT: is modified,
5998 * pcode.c: added definitions for some hardware registers that are needed
6000 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6001 All PCI entries are updated. Now LFSR is supported.
6002 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6003 * added pic16_newpCodeOpLit2 to support instructions with
6004 two literal arguments
6005 * pic16_pCode2str: corrected code that emits assembler instructions
6006 with two literal operands and those that have an access bit modifier
6007 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6008 this fixes a bug which caused some labels to be lost, when an
6009 assembler directive was added, i.e. banksel,
6010 * pic16_FixRegisterBanking: improved logic that causes the insertion
6012 * InlineFunction: functions that are called once, are not any more
6013 inlined. This can be a port option in the future,
6015 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6017 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6018 hold the corresponding uninitialized symbols,
6019 * pic16_allocProcessorRegister: registers have explicit marked the
6021 * pic16_allocInternalRegister: registers are explicit marked as
6023 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6024 processing list, so bit registers were lost,
6027 * ralloc.h: added field 'accessBank' and original symbol operand
6028 in register definition,
6029 * removed the field isMapped from register definition,
6031 ** Several functions have been removed from various sources:
6032 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6033 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6034 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6035 pic16_assignRelocatableRegisters
6037 ** others have been introduced:
6038 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6039 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6041 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6043 * support/scripts/inc2h.pl: changed definition of BIT_AT
6044 to emit 'sbit at' instead of 'bit at'. This was a request.
6046 PIC16 port related preliminary changes:
6047 * gen.c: prefixed function popRegFromString with
6048 pic16_ and all references to it corrected
6049 * pcode.c: all pic16_pc_* hardware registers prefixed
6050 with underscore (_),
6051 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6052 * ralloc.c: newReg(): when register is REG_SFR then
6053 set address to rIdx,
6054 pic16_allocProcessorRegister(): marks register wasUsed=0
6055 pic16_writeUsedRegs(): added a call to assign processor
6056 registers via pic16_assignFixedRegisters
6058 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6060 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6061 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6062 variables in unused register banks. Also the SSEG is placed
6063 wherever there is enough space for it, and IDATA can be anywhere
6064 in internal RAM. For now compile using -Wl-Y[stack_size].
6065 The mem file is different for this option as well, since it
6066 makes no sense of talking about DSEG lenght.
6068 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6070 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6071 in certain cases, e.g. when ROM assignment, patch provided
6072 from Albert den Haan.
6074 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6244 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6246 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

6317 it breaks with bitfields, extern declarations, and gcse analysis.
6318 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6319 could be assigned through a pointer, so don't complain.

7097 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7098 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7099 type for bits was changed. It resulted in bit variables becoming
7100 global, which is not permitted in PIC 14 assembly output.

7117 A few small changes that speed up the peephole optimizer.
7121 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7123 Try to make the peephole optimizer smarter by maintaining
7124 an association between the assembly source code and the
7125 iCodes that originated them. Put this information to use
7126 with a new peephole rule condition "notVolatile" so that
7127 the rules can be aggressive yet still safe.
7132 * src/mcs51/peeph.def
7134 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7138 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7139 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7140 if the left or right operand symbols have the accuse flag set.
7142 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7144 Changed the type of the result of the ! (NOT) operator to char;
7145 previously it returned the same type as the source. This allows
7146 us to eliminate all the genFloatNot functions (all of its target
7147 implementations were very buggy) since !float can use the same

7159 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7160 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7161 during interrupts. Ensure WSAVE is located at a shared bank address.
7162 2. Fixed page selection in some places
7163 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7164 the registers name strings.
7165 4. Fixed "signed / unsigned compare" compiler warnings.
7166 5. The PIC port manages its own allocation of the general purpose
7167 registers, but makes no attempt to reuse them. As a result when
7168 compiling it soon runs out of general purpose registers. Some
7169 additional code was added to the files pcode.c and device.c to walk
7170 through the function call tree and rename the registers so that they
7180 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7187 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7189 Made bitfield a distinct type from bit so that bitfields
7190 convert as per ANSI C and bits retain their traditional
7191 boolean style behaviour. Implemented bitfield support in

7207 access to xdata mapped I/O devices.
7209 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7211 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7213 Cleaned up genPackBits and genUnpackBits and added two helper
7214 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7215 for literal assignments in genPackBits (thanks to Frieder for
7221 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7223 Fixed bug #748310 (pointer to function type mishandled when the
7224 function name is omitted). Also fixed a SIGSEGV when a function
7225 attribute (reentrant, etc) is used on a non-function or on a
7226 function but misplaced before the parameter list.

7255 Made the constant following the "interrupt" keyword optional. If
7256 omitted, the function will not automatically be given an entry
7257 in the interrupt vector table (similar to #pragma NOIV, but
7258 less syntacticly kludgy). The interrupt number is also now
7259 range checked. Also fixed a bug in the high order bit example

7280 unsigned, but are signed by default
7281 * src/SDCCval.c (constVal): rearranged
7282 * src/SDCCval.c (valMod): preliminary fix
7283 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7774 * doc/sdccman.lyx: fixed bug 739745
7775 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
7777 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7779 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7780 it can be defined with CFLAGS when running configure
7781 * src/SDCCmain.c: fixed compiling + linking with object files
7783 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7785 * configure.in: configure for pic16 port,
7786 added --disable-pic16-port
7787 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7788 * src/SDCCmain.c: linkOptions is changed to set *,
7789 added if/endif conditional macros to remove options help
7790 messages from optionsTable when a port is not configured, added
7791 support for the PIc16 port in the ports table, when executing
7792 the compiler with no port specified on command line, a default
7793 port is selected with the new macro DEFAULT_PORT which is
7794 defined in port.h, in setDefaultOptions() linkOptions is removed
7795 from initialization assignment, since now it is a set,
7796 parseCmdLine uses setParseWithComma for linkOptions, in
7797 linkEdit() linkOptions are accessed with new function indexSet()
7798 which returns the i'th item of a set variable. See SDCCset.c, in
7799 linkEdit() when calling buildCmdLine(), added linkOptions as
7800 last argument. Now users can pass arguments to gplink via the
7801 -Wl option, main() uses pic16glue() to glue up pic16 programs
7802 * src/SDCCpeeph.c: various changes to support pic16
7803 * src/SDCCset.c: added function void *indexSet(set *, int) to

7813 * src/pic16/glue.c: commented out some error producing lines
7814 * src/pic16/main.c: __config directives are commented out to stop
7815 gpasm complaining and test the linkage with gplink, _linkCmd and
7816 _asmCmd changed to be more gplink and gpasm friendly
7817 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7818 produced an error when parsed, peep rule 12 is added to utilize
7819 movff, but it is commented out since the pCode does not support
7820 yet a command with 2 address arguments
7822 2003-05-18 <johan AT balder>
7824 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7851 2003-05-11 Borut Razem <borut.razem AT siol.net>
7853 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7854 the path of bin directory, so that PATH is the only env. variable, which has to be set
7855 in case of standard installation.

8842 2003-01-07 <johan AT balder>
8844 * src/SDCCast.c (decorateType): fixed bug #600035

8859 * src/SDCCicode.c: fixed array add
8861 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8862 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8863 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8865 2003-01-04 <johan AT balder>
8867 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8869 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8870 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8872 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8873 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8879 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8880 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8882 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8883 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8885 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8887 * in \sdcc\as\mcs51\ changed these files in order to create an
8888 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8889 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8890 following files to include the previous two files: aslink.dsp,
8891 Makefile.aslink, Makefile.bcc, and Makefile.in.
8893 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8894 .adb instead of .cdb
8896 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8898 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8899 value from option --iram-size.
8901 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8903 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8906 2002-09-18 <wiml AT hhhh.org>
8908 * SDCClrange.h: exposed setFromRange() and setToRange()
8909 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8910 packRegsForAccUse() (bug 542397)
8911 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8912 multiple times and emitting the fetch operations more than once
8913 added aopGetUsesAcc() function to allow binary operators to
8914 fetch their operands in the correct order; made genMinus() emit
8915 compact code for X = LITERAL - Y
8917 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8918 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8919 sprintf() in line 1267.
8921 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8922 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8925 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8926 Changes to aslink (All the changes are marked with 'JCF'):
8928 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8931 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8932 area BSEG. Also moves, if possible, the DATA area down into the internal
8933 ram so more space is available.
8935 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8938 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8939 not bytes. Function summary() which creates a memory usage summary
8940 file with extension .mem. Reports of overlaping stack and small stack
8941 size. If the space for the stack is less than 16 bytes aslink trows a
8944 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8945 the 8051. Option 'y' for memory summary output file.
8947 Changes to sdcc (All the changes are marked with 'JCF'):
8949 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8951 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8952 overlaying area for it (uses RegBankUsed[4]).
8954 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8955 bank zero as used by default. By default aslink locates the stack
8956 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8957 the creation of the .mem file. Delegates the allocation of data area
8958 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8959 the begining of the stack area to aslink.
8961 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8962 glue() in SDCCglue.c creates an area for it.
8964 2002-09-03 Borut Razem <borut.razem AT siol.net>
8965 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8966 sdcc/src/pic/glue.c:
8967 introduced atexit() handler for teporay files removal in case of
8968 errors, assertions, ...
8970 2002-08-29 Borut Razem <borut.razem AT siol.net>
8971 * sdcc/support/cpp2/auto-host_vc_in.h:
8972 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8973 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8974 Maybe there is a similar problem with BORLANDC? It should be checked!
8976 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8977 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8978 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8979 was not executed, and the compiler (cl) launched a warning:
8980 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8982 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8983 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8985 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8986 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8988 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8989 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8990 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8991 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8992 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8993 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8994 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8995 - added Release configuration in VS projects
8996 - review of compiler an linker options
8997 - VC .exe files are generated in bin_vc directory, not to interfere
8998 with binaries generated from other projects (cygwin, mingw, bcc ...)
9000 * sdcc/src/yacc.dsp: added
9002 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9003 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9004 and insert the version number definitions from .version
9006 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9008 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9009 added - genarate auto-host.h using auto-host_vc_in.h as template
9012 removed from CVS, generated automatically
9014 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9015 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9017 2002-08-11 Borut Razem <borut.razem AT siol.net>
9018 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9020 2002-08-10 Borut Razem <borut.razem AT siol.net>
9021 * src/SDCCmain.c (main):
9022 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9023 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9024 The consequence was that some temporary files were not removed.
9027 unification of code in functions tempfilename() and tempfile():
9028 function tempnam() is defined in Visual Studio 6.0 and .NET
9030 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9032 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9033 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9034 - removed compiler command line option /WX: Treats all warnings as errors
9035 - update a list of source files, included into the project
9037 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9038 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9039 changed project type to Generic Project so that can be correcly converted to VS.NET project
9041 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9043 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9045 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9047 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9048 added return 0 statements after assert() to make compiler happy
9050 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9051 added newline in the def file to keep MSC compiler satisfied
9053 * sdcc/src/z80/gen.c:
9054 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9055 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9056 - solved MSC error in function aopDump()
9058 * sdcc_vc.h: define PREFIX as "\\sdcc"
9060 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9061 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9063 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9064 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9065 - Rewrote the register banking algorithm.
9066 - Added pCode live-range analysis to registers (for now, only non-used and
9067 singly-used registers optimized away)
9069 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9071 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
9073 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9074 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9076 2002-04-22 Michael Hope <michaelh AT vroom>
9078 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
