1710 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1712 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1713 * src/z80/main.c (_keywords[]),
1714 * src/SDCCglobal.h (struct options),
1716 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1717 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1718 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1719 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1720 always available in leading double underscore form. The C99 support is
1721 mostly missing, but it's a start.
1722 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1723 reserved identifier "__data".
1725 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1727 * src/mcs51/peeph.def: fixed bug 1170013

1738 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1740 * src/port.h (struct PORT),
1741 * src/avr/ralloc.c (avr_assignRegisters),
1743 * src/ds390/ralloc.c (ds390_assignRegisters),
1745 * src/hc08/ralloc.c (hc08_assignRegisters),

1757 * src/SDCCopt.c (eBBlockFromiCode, replaceRegEqv, killDeadCode),
1758 * src/SDCCcse.c (ifxOptimize, cseBBlock, cseAllBlocks),
1760 * src/SDCCdflow.c (computeDataFlow),

1767 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1768 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1769 immedDom() returning wrong block; probably fixes bug #1160833)
1771 2005-03-20 Borut Razem <borut.razem AT siol.net>
1773 * support/scripts/inc2h.pl: WIN32 port
1775 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1777 * device/lib/makefile.in: added abs.c and labs.c
1779 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1781 * device/include/stdint.h: added
1782 * device/lib/abs.c: added
1783 * device/lib/labs.c: added
1784 * device/include/stdlib.h: added abs() and labs() prototypes
1785 * device/lib/libsdcc.lib: added abs and labs
1786 * device/include/float.h,

1799 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1801 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1803 * device/lib/printf_large.c: removed inline assembly for portability and
1804 readability. Use printf_fast if speed or size are more important.
1805 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1806 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1808 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1810 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1811 prevent compiler warning
1813 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1815 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1816 moved to level 0 and declared as static. Also they are explicit
1817 placed in access bank. This was necessery because some times they
1818 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1819 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1820 optimizations. Currently only compare to unsigned char is implemented,
1821 * src/pic16/gen.c: added fReturnIdx array,
1822 * (struct resolvedIfx) is moved to gen.h and made public,
1823 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1824 * (aopForSym): added an optimization to directly store in stack of
1825 the operand of a SEND iCode,
1826 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1827 but as registers instead (AOP_REG) using the fReturnIdx array,
1828 * (pic16_freeAsmop): remove the freed register from the
1829 _G.sregsAlloc field,
1830 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1831 a compare of 'WREG',
1832 * (pic16_popGetTempRegCond): changed function prototype, now
1833 function takes also a bitVector argument v which holds the current
1834 set of registers that are allocated for stack access by aopForSym,
1835 registers allocated in aopForSym for accessing stack symbols are not
1836 any more part of the functions usedRegs field,
1837 * (genCall): some times aopOp is called for a stack variable to be
1838 send, aopForSym might perform the push, if this is true make sure
1839 that genCall doesn't push the variable twice by testing _G.resDirect,
1840 * (genFunction): changed testing for unspecified interrupt number
1841 from 256 to INTNO_UNSPEC,
1842 * modified selection scheme of frame pointer generation. Previously
1843 if function did use local registers a frame pointer was generated,
1844 now a frame pointer is generated only if function has arguments
1845 (that need PLUSW2 register access), or has stack arguments, or the
1846 compiler is not instructed to omit the frame pointer,
1847 * (genEndFunction): before restoring local registers that were saved
1848 in the function preamble, also restore the registers that *might*
1849 have been allocated for stack access,
1850 * (genRet): removed some old comments,
1851 * (genCmp, the active (RN's) version): added a call to the
1852 pic16_genCmp_special function to perform the compare with a more
1853 robust and optimized way,
1854 * (genInline): a feature has been added in inline code generation,
1855 which allows a wildcard variable substitution when writing inline
1856 assembly. Code is incomplete and experimental therefore undocumented,
1857 * (genCast): changed order of aopOp for result and right to allow
1858 aopForSym to directly load the result if possible,
1859 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1860 perform an optimized compare on some selected special occasions,
1861 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1862 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1863 generate an IVT any more,
1864 * src/pic16/main.c (pic16_optionsTable): added command line option
1866 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1867 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1869 * src/pic16/NOTES: Raphael Neider added in list of active developers
1870 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1871 jumptable_end to prevent bug #,
1872 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1873 inCond and outCond fields,
1874 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1875 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1876 turn off register spilling,
1877 * (packRegsForOneUse): synced with other ports' versions although it
1878 is not used currently,
1879 * (pic16_packRegisters): added an optimization while reading
1880 structure bitfields, some registers may be saved (malloc code is
1881 decreased by 80 bytes)
1883 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1885 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1886 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1887 this can be optimized more?
1889 2005-03-10 Raphael Neider <rneider AT web.de>
1891 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1892 genNearPointerGet): (hopefully) fixed access to bitfields via
1893 pointers (p->bitN = x; and x = p->bitN; failed)
1895 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2083 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2084 this might fix SIGSEGVs on MinGW...
2085 * src/SDCCopt.c (killDeadCode): restored original behaviour
2086 (volatile operands might get thrown away though)
2088 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2527 Adding support for replacing ljmps with sjmps in jumptables
2528 generated for switch statements. For now you need to set the
2529 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2530 Now 4 algorithms for mcs51 jumptable generation are used:
2531 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2532 addresses loaded pc-relative for up to 112 cases and stack-pushing
2533 target addresses loaded with offset from dptr for up to 256 cases.

2560 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2561 to call when a stack overflow occurs,
2562 * (malloc.h): added CVS Id tag,
2563 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2565 * added libc directory. The current version of LibC contains string
2566 functions, ctype functions and macros and some functions of the
2567 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2568 be extensively tested in the future. Standard disclaimer here.
2569 Library is not automatically build yet. But one can build it by
2570 invoking 'make' inside the libc directory.
2571 * added ADC library under libio. Preliminary version yet.
2573 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

2580 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2581 * (pic16_storeForReturn): optimized return of 0,
2582 * (genCmp): experimental code for new genCmp which uses PIC18's
2583 special compare&skip instructions. Initial tests fail some times
2584 with variables grater than 1 byte in size, so new code is disabled,

5611 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5613 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5614 loaded with the linker search paths (-L arguments) and the libraries
5615 to be linked with the current source (-l arguments). Changes
5616 currently will affect only the pic16 port.
5617 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5618 include path the port specific paths and port specific libraries,
5619 * gplink command now contains the $3 argument,
5620 * src/pic16/device.h,
5621 * src/pic16/device.c,: structure PIC_device is made public and
5622 renamed to PIC16_device, the same for variable Pics which is renamed

5637 Documenting changes from previous commits.
5638 * configure.in (version 1.56),
5639 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5640 when generating output files to configure the pic16 library,
5641 but now I've commented it out, since gputils aren't installed in the
5642 SF compile farm, so library won't compile
5644 * device/lib/Makefile.in (version 1.56): initially I've added in
5645 target 'all' the prerequestive 'model-pic16' so it compiled the
5646 pic16 library, but now I've commented it out for the same reasons
5648 * added targets 'model-pic16' and 'objects-pic16' to compile the
5650 * added target 'port-specific-objects-pic16' to handle the
5651 generated libraries and copy them into the build/ directory
5652 * added target 'clean-intermediate-pic16' to clean intermediate
5653 files into pic16 directory
5654 * in target 'installdirs' added line to create directory pic16 in
5655 the installation path
5657 * device/include/Makefile.in (version 1.11): in target 'install'
5658 added lines to copy all header files to installation path,
5659 * in target 'installdirs' added line create directory for pic16
5660 headers in the installation path

5675 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5676 option so that it actually works. Made it specific to the z80, since
5677 the gbz80 doesn't have these kinds of I/O ports.
5679 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5681 * device/include/z180.h,

5705 via literal number. The symbol is placed in the corresponding
5706 position of the data ram
5707 * (pic16_dump_section): relocatable and absolute uninitialized
5708 data are now emitted in sorted order to reduce section naming,
5709 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5710 weren't marked as being in the access bank,
5712 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5714 Added portion of GNU PIC Library under the directory
5715 device/include/pic16 and device/lib/pic16. These files
5716 contain the declarations of SFRs for the PIC18Fxx2 devices.
5717 The directory is initialized via configure from toplevel.
5719 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5746 * doc/sdccman.lyx: Moved and added some sections, small changes
5747 all over. Telling LaTeX to be less strict with word spacing
5748 to better keep the right margin. Changed some notes about
5749 maintainance of the ports in section 3.2.1 - is it OK like this?
5751 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5789 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5791 * src/pic16/peeph.def: all peepholes with movff are commented out,
5792 because there is a problem in the pcode peep optimizer,
5793 * src/pic16/ralloc.c: the register allocator can now reuse local

5870 2004-01-07 Borut Razem <borut.razem AT siol.net>
5872 * support/scripts/sdcc.nsi: update PATH
5873 * support/scripts/sdcc.ico: craeted

5886 include information about variables allocated to the overlay
5889 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5891 * as/mcs51/lkmain.c: Help about -Y option

5903 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5905 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5906 (default behaviour).
5908 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5910 A python script to validate compiler diagnostic messages. It can be
5911 used to verify that sdcc complains about bad c source code and
5912 gives a good location of the error.
5913 * support/valdiag/Makefile,
5914 * support/valdiag/valdiag.py,
5915 * support/valdiag/tests/*
5917 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5930 * src/common.h: added ifndef/define/endif macros
5931 around the header file.
5932 Bug reported from Jesus Calvino-Fraga
5934 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5936 * sdcc.spec: updated
5937 * device/include/Makefile.in: don't install CVS directories
5938 * device/lib/Makefile.in: added removal of CVS directories after install
5939 * doc/Makefile: fixed install, added local_icons
5940 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5941 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5942 * src/ds390/gen.c (genRightShift): fixed bug #870788
5943 * src/SDCCast.c (decorateType): fixed bug #870781
5945 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5947 PIC16 port related changes:
5948 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5949 added variable stackPos,
5951 * gen.c: genCall, assignResultValue: added support for
5952 pushing/retrieving function parameters to/from stack,
5953 genFunction,genEndFunction: setup stack frame for the
5955 genAddrOf: will be changed according to bug 863624
5957 * added files genutils.c and genutils.h which contain gen*
5958 debugged and optimised functions extracted from gen.c
5960 * glue.c: added variable 'externs' which holds extern symbols,
5961 pic16emitRegularMap: is modified to properly handle relocatable
5962 symbols under the new scheme,
5963 pic16createInterruptVect: is modified
5964 pic16printPublics: is modified to emit 'global' assembler directives,
5965 added pic16_printExterns to print extern symbols,
5966 pic16glue: initializes stack/frame pointer in the beginning of
5967 the assembly output. Temporary hack, will be corrected later,
5968 because gplink yet does not support stack and SDCC does not
5969 yet support a type of crt0.o object to create the final binary.
5971 * Removed many lines that contain 8051 legacy code.
5972 * The code is finally placed under a 'code' directive.
5973 * Added port specific options.
5975 * _process_pragma: simplified since now we do not need *special*
5976 include file to define SFR registers. But a separate header
5977 will be needed. This will be developed later.
5978 * _pic16_parseOptions: added, parses port specific options:
5979 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5980 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5981 --preplace-udata-with=
5983 * _pic16_setDefaultOptions: modified to initialize section names,
5984 but hack is temporarly out of order since it needs improvement.
5985 * _pic16_genAssemblerPreamble: configuration words are emitted by
5986 their address instead of their name. This part is incomplete and
5987 supports only the 18Fxx2 devices. Other devices will emit an error
5988 during assembly since they do not contain the same set of config
5990 * _pic16_genIVT: is modified,
5992 * pcode.c: added definitions for some hardware registers that are needed
5994 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5995 All PCI entries are updated. Now LFSR is supported.
5996 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5997 * added pic16_newpCodeOpLit2 to support instructions with
5998 two literal arguments
5999 * pic16_pCode2str: corrected code that emits assembler instructions
6000 with two literal operands and those that have an access bit modifier
6001 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6002 this fixes a bug which caused some labels to be lost, when an
6003 assembler directive was added, i.e. banksel,
6004 * pic16_FixRegisterBanking: improved logic that causes the insertion
6006 * InlineFunction: functions that are called once, are not any more
6007 inlined. This can be a port option in the future,
6009 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6011 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6012 hold the corresponding uninitialized symbols,
6013 * pic16_allocProcessorRegister: registers have explicit marked the
6015 * pic16_allocInternalRegister: registers are explicit marked as
6017 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6018 processing list, so bit registers were lost,
6021 * ralloc.h: added field 'accessBank' and original symbol operand
6022 in register definition,
6023 * removed the field isMapped from register definition,
6025 ** Several functions have been removed from various sources:
6026 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6027 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6028 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6029 pic16_assignRelocatableRegisters
6031 ** others have been introduced:
6032 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6033 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6035 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6037 * support/scripts/inc2h.pl: changed definition of BIT_AT
6038 to emit 'sbit at' instead of 'bit at'. This was a request.
6040 PIC16 port related preliminary changes:
6041 * gen.c: prefixed function popRegFromString with
6042 pic16_ and all references to it corrected
6043 * pcode.c: all pic16_pc_* hardware registers prefixed
6044 with underscore (_),
6045 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6046 * ralloc.c: newReg(): when register is REG_SFR then
6047 set address to rIdx,
6048 pic16_allocProcessorRegister(): marks register wasUsed=0
6049 pic16_writeUsedRegs(): added a call to assign processor
6050 registers via pic16_assignFixedRegisters
6052 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6054 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6055 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6056 variables in unused register banks. Also the SSEG is placed
6057 wherever there is enough space for it, and IDATA can be anywhere
6058 in internal RAM. For now compile using -Wl-Y[stack_size].
6059 The mem file is different for this option as well, since it
6060 makes no sense of talking about DSEG lenght.
6062 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6064 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6065 in certain cases, e.g. when ROM assignment, patch provided
6066 from Albert den Haan.
6068 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6211 * src/mcs51/peephole.def,
6212 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6213 (allows non-interrupt and interrupt code to safely compete for a resource
6214 without the non-interrupt code having to disable interrupts)
6216 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6218 * src/SDCCicode.c (geniCodeAdd),

6238 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6240 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
6242 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6311 it breaks with bitfields, extern declarations, and gcse analysis.
6312 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6313 could be assigned through a pointer, so don't complain.

7091 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7092 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7093 type for bits was changed. It resulted in bit variables becoming
7094 global, which is not permitted in PIC 14 assembly output.

7111 A few small changes that speed up the peephole optimizer.
7115 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7117 Try to make the peephole optimizer smarter by maintaining
7118 an association between the assembly source code and the
7119 iCodes that originated them. Put this information to use
7120 with a new peephole rule condition "notVolatile" so that
7121 the rules can be aggressive yet still safe.
7126 * src/mcs51/peeph.def
7128 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7132 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7133 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7134 if the left or right operand symbols have the accuse flag set.
7136 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7138 Changed the type of the result of the ! (NOT) operator to char;
7139 previously it returned the same type as the source. This allows
7140 us to eliminate all the genFloatNot functions (all of its target
7141 implementations were very buggy) since !float can use the same
7144 * src/SDCCicode.c (ast2iCode): ! returns char

7153 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7154 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7155 during interrupts. Ensure WSAVE is located at a shared bank address.
7156 2. Fixed page selection in some places
7157 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7158 the registers name strings.
7159 4. Fixed "signed / unsigned compare" compiler warnings.
7160 5. The PIC port manages its own allocation of the general purpose
7161 registers, but makes no attempt to reuse them. As a result when
7162 compiling it soon runs out of general purpose registers. Some
7163 additional code was added to the files pcode.c and device.c to walk
7164 through the function call tree and rename the registers so that they
7174 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7181 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7183 Made bitfield a distinct type from bit so that bitfields
7184 convert as per ANSI C and bits retain their traditional
7185 boolean style behaviour. Implemented bitfield support in
7193 * src/ds390/gen.c: bit v bitfield split
7194 * src/z80/gen.c: New support for bitfields
7195 * support/regression/tests/bitfields.c: reenabled z80,
7198 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7249 Made the constant following the "interrupt" keyword optional. If
7250 omitted, the function will not automatically be given an entry
7251 in the interrupt vector table (similar to #pragma NOIV, but
7252 less syntacticly kludgy). The interrupt number is also now
7253 range checked. Also fixed a bug in the high order bit example

7775 * src/SDCCmain.c: fixed compiling + linking with object files
7777 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7779 * configure.in: configure for pic16 port,
7780 added --disable-pic16-port
7781 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7782 * src/SDCCmain.c: linkOptions is changed to set *,
7783 added if/endif conditional macros to remove options help
7784 messages from optionsTable when a port is not configured, added
7785 support for the PIc16 port in the ports table, when executing
7786 the compiler with no port specified on command line, a default
7787 port is selected with the new macro DEFAULT_PORT which is
7788 defined in port.h, in setDefaultOptions() linkOptions is removed
7789 from initialization assignment, since now it is a set,
7790 parseCmdLine uses setParseWithComma for linkOptions, in
7791 linkEdit() linkOptions are accessed with new function indexSet()
7792 which returns the i'th item of a set variable. See SDCCset.c, in
7793 linkEdit() when calling buildCmdLine(), added linkOptions as
7794 last argument. Now users can pass arguments to gplink via the
7795 -Wl option, main() uses pic16glue() to glue up pic16 programs
7796 * src/SDCCpeeph.c: various changes to support pic16
7797 * src/SDCCset.c: added function void *indexSet(set *, int) to

7805 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
7807 * src/pic16/glue.c: commented out some error producing lines
7808 * src/pic16/main.c: __config directives are commented out to stop
7809 gpasm complaining and test the linkage with gplink, _linkCmd and
7810 _asmCmd changed to be more gplink and gpasm friendly
7811 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7812 produced an error when parsed, peep rule 12 is added to utilize
7813 movff, but it is commented out since the pCode does not support
7814 yet a command with 2 address arguments
7816 2003-05-18 <johan AT balder>

7845 2003-05-11 Borut Razem <borut.razem AT siol.net>
7847 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

8853 * src/SDCCicode.c: fixed array add
8855 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8856 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8857 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8859 2003-01-04 <johan AT balder>
8861 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8863 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8864 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8866 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8876 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8877 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8879 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8881 * in \sdcc\as\mcs51\ changed these files in order to create an
8882 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8883 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8884 following files to include the previous two files: aslink.dsp,
8885 Makefile.aslink, Makefile.bcc, and Makefile.in.
8887 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8888 .adb instead of .cdb
8890 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8892 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8893 value from option --iram-size.
8895 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8897 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8900 2002-09-18 <wiml AT hhhh.org>
8902 * SDCClrange.h: exposed setFromRange() and setToRange()
8903 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8904 packRegsForAccUse() (bug 542397)
8905 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8906 multiple times and emitting the fetch operations more than once
8907 added aopGetUsesAcc() function to allow binary operators to
8908 fetch their operands in the correct order; made genMinus() emit
8909 compact code for X = LITERAL - Y
8911 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8912 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8913 sprintf() in line 1267.
8915 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8916 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8919 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8920 Changes to aslink (All the changes are marked with 'JCF'):
8922 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8925 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8926 area BSEG. Also moves, if possible, the DATA area down into the internal
8927 ram so more space is available.
8929 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8932 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8933 not bytes. Function summary() which creates a memory usage summary
8934 file with extension .mem. Reports of overlaping stack and small stack
8935 size. If the space for the stack is less than 16 bytes aslink trows a
8938 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8939 the 8051. Option 'y' for memory summary output file.
8941 Changes to sdcc (All the changes are marked with 'JCF'):
8943 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8945 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8946 overlaying area for it (uses RegBankUsed[4]).
8948 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8949 bank zero as used by default. By default aslink locates the stack
8950 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8951 the creation of the .mem file. Delegates the allocation of data area
8952 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8953 the begining of the stack area to aslink.
8955 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8956 glue() in SDCCglue.c creates an area for it.
8958 2002-09-03 Borut Razem <borut.razem AT siol.net>
8959 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8960 sdcc/src/pic/glue.c:
8961 introduced atexit() handler for teporay files removal in case of
8962 errors, assertions, ...
8964 2002-08-29 Borut Razem <borut.razem AT siol.net>
8965 * sdcc/support/cpp2/auto-host_vc_in.h:
8966 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8967 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8968 Maybe there is a similar problem with BORLANDC? It should be checked!
8970 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8971 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8972 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8973 was not executed, and the compiler (cl) launched a warning:
8974 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8976 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8977 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8979 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8980 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8982 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8983 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8984 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8985 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8986 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8987 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8988 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8989 - added Release configuration in VS projects
8990 - review of compiler an linker options
8991 - VC .exe files are generated in bin_vc directory, not to interfere
8992 with binaries generated from other projects (cygwin, mingw, bcc ...)
8994 * sdcc/src/yacc.dsp: added
8996 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8997 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8998 and insert the version number definitions from .version
9000 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9002 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9003 added - genarate auto-host.h using auto-host_vc_in.h as template
9006 removed from CVS, generated automatically
9008 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9009 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9011 2002-08-11 Borut Razem <borut.razem AT siol.net>
9012 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9014 2002-08-10 Borut Razem <borut.razem AT siol.net>
9015 * src/SDCCmain.c (main):
9016 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9017 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9018 The consequence was that some temporary files were not removed.
9021 unification of code in functions tempfilename() and tempfile():
9022 function tempnam() is defined in Visual Studio 6.0 and .NET
9024 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9026 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9027 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9028 - removed compiler command line option /WX: Treats all warnings as errors
9029 - update a list of source files, included into the project
9031 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9032 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9033 changed project type to Generic Project so that can be correcly converted to VS.NET project
9035 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9037 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9039 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9041 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9042 added return 0 statements after assert() to make compiler happy
9044 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9045 added newline in the def file to keep MSC compiler satisfied
9047 * sdcc/src/z80/gen.c:
9048 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9049 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9050 - solved MSC error in function aopDump()
9052 * sdcc_vc.h: define PREFIX as "\\sdcc"
9054 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9055 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9057 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9058 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9059 - Rewrote the register banking algorithm.
9060 - Added pCode live-range analysis to registers (for now, only non-used and
9061 singly-used registers optimized away)
9063 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9065 * 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.
9067 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9068 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9070 2002-04-22 Michael Hope <michaelh AT vroom>
9072 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
9074 * configure.in (DD_COPT): Added include support required for gbdk.
