1719 * src/SDCCdflow.c (computeDataFlow),
1721 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
1723 * src/SDCCcflow.c (*),
1725 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1726 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1727 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1728 immedDom() returning wrong block; probably fixes bug #1160833)
1730 2005-03-20 Borut Razem <borut.razem AT siol.net>
1732 * support/scripts/inc2h.pl: WIN32 port
1734 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1736 * device/lib/makefile.in: added abs.c and labs.c
1738 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1740 * device/include/stdint.h: added
1741 * device/lib/abs.c: added
1742 * device/lib/labs.c: added
1743 * device/include/stdlib.h: added abs() and labs() prototypes
1744 * device/lib/libsdcc.lib: added abs and labs
1745 * device/include/float.h,
1746 * device/lib/_fsmul.c,
1747 * device/lib/printf_fast.c,
1748 * device/lib/printf_tiny.c: updated comments
1750 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1752 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1755 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1757 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1758 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1760 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1762 * device/lib/printf_large.c: removed inline assembly for portability and
1763 readability. Use printf_fast if speed or size are more important.
1764 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1765 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1767 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1769 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1770 prevent compiler warning
1772 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1774 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1775 moved to level 0 and declared as static. Also they are explicit
1776 placed in access bank. This was necessery because some times they
1777 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1778 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1779 optimizations. Currently only compare to unsigned char is implemented,
1780 * src/pic16/gen.c: added fReturnIdx array,
1781 * (struct resolvedIfx) is moved to gen.h and made public,
1782 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1783 * (aopForSym): added an optimization to directly store in stack of
1784 the operand of a SEND iCode,
1785 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1786 but as registers instead (AOP_REG) using the fReturnIdx array,
1787 * (pic16_freeAsmop): remove the freed register from the
1788 _G.sregsAlloc field,
1789 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1790 a compare of 'WREG',
1791 * (pic16_popGetTempRegCond): changed function prototype, now
1792 function takes also a bitVector argument v which holds the current
1793 set of registers that are allocated for stack access by aopForSym,
1794 registers allocated in aopForSym for accessing stack symbols are not
1795 any more part of the functions usedRegs field,
1796 * (genCall): some times aopOp is called for a stack variable to be
1797 send, aopForSym might perform the push, if this is true make sure
1798 that genCall doesn't push the variable twice by testing _G.resDirect,
1799 * (genFunction): changed testing for unspecified interrupt number
1800 from 256 to INTNO_UNSPEC,
1801 * modified selection scheme of frame pointer generation. Previously
1802 if function did use local registers a frame pointer was generated,
1803 now a frame pointer is generated only if function has arguments
1804 (that need PLUSW2 register access), or has stack arguments, or the
1805 compiler is not instructed to omit the frame pointer,
1806 * (genEndFunction): before restoring local registers that were saved
1807 in the function preamble, also restore the registers that *might*
1808 have been allocated for stack access,
1809 * (genRet): removed some old comments,
1810 * (genCmp, the active (RN's) version): added a call to the
1811 pic16_genCmp_special function to perform the compare with a more
1812 robust and optimized way,
1813 * (genInline): a feature has been added in inline code generation,
1814 which allows a wildcard variable substitution when writing inline
1815 assembly. Code is incomplete and experimental therefore undocumented,
1816 * (genCast): changed order of aopOp for result and right to allow
1817 aopForSym to directly load the result if possible,
1818 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1819 perform an optimized compare on some selected special occasions,
1820 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1821 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1822 generate an IVT any more,
1823 * src/pic16/main.c (pic16_optionsTable): added command line option
1825 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1826 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1828 * src/pic16/NOTES: Raphael Neider added in list of active developers
1829 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1830 jumptable_end to prevent bug #,
1831 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1832 inCond and outCond fields,
1833 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1834 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1835 turn off register spilling,
1836 * (packRegsForOneUse): synced with other ports' versions although it
1837 is not used currently,
1838 * (pic16_packRegisters): added an optimization while reading
1839 structure bitfields, some registers may be saved (malloc code is
1840 decreased by 80 bytes)
1842 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1844 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1845 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1846 this can be optimized more?
1848 2005-03-10 Raphael Neider <rneider AT web.de>
1850 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1851 genNearPointerGet): (hopefully) fixed access to bitfields via
1852 pointers (p->bitN = x; and x = p->bitN; failed)
1854 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1897 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1898 to keep the correct label reference count when adding/removing references
1899 to labels. A peephole file using this is appended to patch #1144962.

2042 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2043 this might fix SIGSEGVs on MinGW...

2487 generated for switch statements. For now you need to set the
2488 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2489 Now 4 algorithms for mcs51 jumptable generation are used:
2490 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2522 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2524 * added libc directory. The current version of LibC contains string
2525 functions, ctype functions and macros and some functions of the
2526 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2527 be extensively tested in the future. Standard disclaimer here.
2528 Library is not automatically build yet. But one can build it by

2540 * (pic16_storeForReturn): optimized return of 0,
2541 * (genCmp): experimental code for new genCmp which uses PIC18's
2542 special compare&skip instructions. Initial tests fail some times
2543 with variables grater than 1 byte in size, so new code is disabled,
2544 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2546 * (genCast): began a fix to optimize the casting of a bit to another
2547 bit, now assigning a bitfield to another bitfield will fail, sorry,

2556 and 1 for banking instruction,
2557 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2558 caused stop processing pCodes after a inline assembly block,
2559 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2561 registers when it shouldn't,
2562 * src/pic16/ralloc.c (allocReg): add preliminary support for
2563 supporting a limited set of temporary registers,
2565 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2567 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2568 genDataPointerSet): ensure assignments always copy in MSB to LSB
2570 (loadRegFromAop): recognize CLRH optimization,
2571 (genFunction): optimize RECEIVE iCodes in reentrant functions
2573 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2575 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2584 * device/lib/_gptrget.c (_gptrget),
2585 * device/lib/_gptrgetc.c (_gptrgetc),

5570 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5572 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5573 loaded with the linker search paths (-L arguments) and the libraries
5574 to be linked with the current source (-l arguments). Changes
5575 currently will affect only the pic16 port.
5576 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5577 include path the port specific paths and port specific libraries,
5578 * gplink command now contains the $3 argument,
5579 * src/pic16/device.h,

5596 Documenting changes from previous commits.
5597 * configure.in (version 1.56),
5598 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5599 when generating output files to configure the pic16 library,
5600 but now I've commented it out, since gputils aren't installed in the
5601 SF compile farm, so library won't compile
5603 * device/lib/Makefile.in (version 1.56): initially I've added in
5604 target 'all' the prerequestive 'model-pic16' so it compiled the
5605 pic16 library, but now I've commented it out for the same reasons
5607 * added targets 'model-pic16' and 'objects-pic16' to compile the
5609 * added target 'port-specific-objects-pic16' to handle the
5610 generated libraries and copy them into the build/ directory
5611 * added target 'clean-intermediate-pic16' to clean intermediate
5612 files into pic16 directory
5613 * in target 'installdirs' added line to create directory pic16 in
5614 the installation path

5617 added lines to copy all header files to installation path,
5618 * in target 'installdirs' added line create directory for pic16
5619 headers in the installation path

5635 option so that it actually works. Made it specific to the z80, since
5636 the gbz80 doesn't have these kinds of I/O ports.
5638 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5640 * device/include/z180.h,

5667 data are now emitted in sorted order to reduce section naming,
5668 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5669 weren't marked as being in the access bank,

5673 Added portion of GNU PIC Library under the directory
5674 device/include/pic16 and device/lib/pic16. These files
5675 contain the declarations of SFRs for the PIC18Fxx2 devices.
5676 The directory is initialized via configure from toplevel.

5705 * doc/sdccman.lyx: Moved and added some sections, small changes
5706 all over. Telling LaTeX to be less strict with word spacing
5707 to better keep the right margin. Changed some notes about
5708 maintainance of the ports in section 3.2.1 - is it OK like this?
5710 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5712 SDCC source changes:
5713 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5747 UPPER for immediate operands,
5748 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5750 * src/pic16/peeph.def: all peepholes with movff are commented out,
5751 because there is a problem in the pcode peep optimizer,
5752 * src/pic16/ralloc.c: the register allocator can now reuse local

5845 include information about variables allocated to the overlay
5848 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5850 * as/mcs51/lkmain.c: Help about -Y option

5862 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5864 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5865 (default behaviour).
5867 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5869 A python script to validate compiler diagnostic messages. It can be
5870 used to verify that sdcc complains about bad c source code and
5871 gives a good location of the error.
5872 * support/valdiag/Makefile,
5873 * support/valdiag/valdiag.py,
5874 * support/valdiag/tests/*
5876 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5889 * src/common.h: added ifndef/define/endif macros
5890 around the header file.
5891 Bug reported from Jesus Calvino-Fraga
5893 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5895 * sdcc.spec: updated
5896 * device/include/Makefile.in: don't install CVS directories
5897 * device/lib/Makefile.in: added removal of CVS directories after install
5898 * doc/Makefile: fixed install, added local_icons
5899 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5900 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5901 * src/ds390/gen.c (genRightShift): fixed bug #870788
5902 * src/SDCCast.c (decorateType): fixed bug #870781
5904 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5906 PIC16 port related changes:
5907 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5908 added variable stackPos,
5910 * gen.c: genCall, assignResultValue: added support for
5911 pushing/retrieving function parameters to/from stack,
5912 genFunction,genEndFunction: setup stack frame for the
5914 genAddrOf: will be changed according to bug 863624
5916 * added files genutils.c and genutils.h which contain gen*
5917 debugged and optimised functions extracted from gen.c
5919 * glue.c: added variable 'externs' which holds extern symbols,
5920 pic16emitRegularMap: is modified to properly handle relocatable
5921 symbols under the new scheme,
5922 pic16createInterruptVect: is modified
5923 pic16printPublics: is modified to emit 'global' assembler directives,
5924 added pic16_printExterns to print extern symbols,
5925 pic16glue: initializes stack/frame pointer in the beginning of
5926 the assembly output. Temporary hack, will be corrected later,
5927 because gplink yet does not support stack and SDCC does not
5928 yet support a type of crt0.o object to create the final binary.
5930 * Removed many lines that contain 8051 legacy code.
5931 * The code is finally placed under a 'code' directive.
5932 * Added port specific options.
5934 * _process_pragma: simplified since now we do not need *special*
5935 include file to define SFR registers. But a separate header
5936 will be needed. This will be developed later.
5937 * _pic16_parseOptions: added, parses port specific options:
5938 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5939 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5940 --preplace-udata-with=
5942 * _pic16_setDefaultOptions: modified to initialize section names,
5943 but hack is temporarly out of order since it needs improvement.
5944 * _pic16_genAssemblerPreamble: configuration words are emitted by
5945 their address instead of their name. This part is incomplete and
5946 supports only the 18Fxx2 devices. Other devices will emit an error
5947 during assembly since they do not contain the same set of config
5949 * _pic16_genIVT: is modified,
5951 * pcode.c: added definitions for some hardware registers that are needed
5953 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5954 All PCI entries are updated. Now LFSR is supported.
5955 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5956 * added pic16_newpCodeOpLit2 to support instructions with
5957 two literal arguments
5958 * pic16_pCode2str: corrected code that emits assembler instructions
5959 with two literal operands and those that have an access bit modifier
5960 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5961 this fixes a bug which caused some labels to be lost, when an
5962 assembler directive was added, i.e. banksel,
5963 * pic16_FixRegisterBanking: improved logic that causes the insertion
5965 * InlineFunction: functions that are called once, are not any more
5966 inlined. This can be a port option in the future,
5968 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5970 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5971 hold the corresponding uninitialized symbols,
5972 * pic16_allocProcessorRegister: registers have explicit marked the
5974 * pic16_allocInternalRegister: registers are explicit marked as
5976 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5977 processing list, so bit registers were lost,
5980 * ralloc.h: added field 'accessBank' and original symbol operand
5981 in register definition,
5982 * removed the field isMapped from register definition,
5984 ** Several functions have been removed from various sources:
5985 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5986 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5987 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5988 pic16_assignRelocatableRegisters
5990 ** others have been introduced:
5991 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5992 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5994 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5996 * support/scripts/inc2h.pl: changed definition of BIT_AT
5997 to emit 'sbit at' instead of 'bit at'. This was a request.
5999 PIC16 port related preliminary changes:
6000 * gen.c: prefixed function popRegFromString with
6001 pic16_ and all references to it corrected
6002 * pcode.c: all pic16_pc_* hardware registers prefixed
6003 with underscore (_),
6004 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6005 * ralloc.c: newReg(): when register is REG_SFR then
6006 set address to rIdx,
6007 pic16_allocProcessorRegister(): marks register wasUsed=0
6008 pic16_writeUsedRegs(): added a call to assign processor
6009 registers via pic16_assignFixedRegisters
6011 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6013 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6014 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6015 variables in unused register banks. Also the SSEG is placed
6016 wherever there is enough space for it, and IDATA can be anywhere
6017 in internal RAM. For now compile using -Wl-Y[stack_size].
6018 The mem file is different for this option as well, since it
6019 makes no sense of talking about DSEG lenght.
6021 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6023 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6024 in certain cases, e.g. when ROM assignment, patch provided
6025 from Albert den Haan.
6027 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6170 * src/mcs51/peephole.def,
6171 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6172 (allows non-interrupt and interrupt code to safely compete for a resource

7050 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7051 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7070 A few small changes that speed up the peephole optimizer.
7074 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7076 Try to make the peephole optimizer smarter by maintaining
7077 an association between the assembly source code and the
7078 iCodes that originated them. Put this information to use
7079 with a new peephole rule condition "notVolatile" so that
7080 the rules can be aggressive yet still safe.
7085 * src/mcs51/peeph.def
7087 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7091 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7092 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7093 if the left or right operand symbols have the accuse flag set.
7095 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7097 Changed the type of the result of the ! (NOT) operator to char;
7098 previously it returned the same type as the source. This allows
7099 us to eliminate all the genFloatNot functions (all of its target
7100 implementations were very buggy) since !float can use the same
7103 * src/SDCCicode.c (ast2iCode): ! returns char

7112 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7113 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7114 during interrupts. Ensure WSAVE is located at a shared bank address.
7115 2. Fixed page selection in some places
7116 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7117 the registers name strings.
7118 4. Fixed "signed / unsigned compare" compiler warnings.
7119 5. The PIC port manages its own allocation of the general purpose
7120 registers, but makes no attempt to reuse them. As a result when
7121 compiling it soon runs out of general purpose registers. Some
7122 additional code was added to the files pcode.c and device.c to walk
7123 through the function call tree and rename the registers so that they
7133 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7134 genPlus() & genMinus() when the result is the same as left or right

7140 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7142 Made bitfield a distinct type from bit so that bitfields
7143 convert as per ANSI C and bits retain their traditional
7144 boolean style behaviour. Implemented bitfield support in
7152 * src/ds390/gen.c: bit v bitfield split
7153 * src/z80/gen.c: New support for bitfields
7154 * support/regression/tests/bitfields.c: reenabled z80,
7157 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7159 Rules 246.x, 247.x relate to bitfields, the others speed up
7160 access to xdata mapped I/O devices.
7162 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7164 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7166 Cleaned up genPackBits and genUnpackBits and added two helper

7176 Fixed bug #748310 (pointer to function type mishandled when the
7177 function name is omitted). Also fixed a SIGSEGV when a function
7178 attribute (reentrant, etc) is used on a non-function or on a
7179 function but misplaced before the parameter list.

7208 Made the constant following the "interrupt" keyword optional. If
7209 omitted, the function will not automatically be given an entry
7210 in the interrupt vector table (similar to #pragma NOIV, but
7211 less syntacticly kludgy). The interrupt number is also now
7212 range checked. Also fixed a bug in the high order bit example
7219 * support/Util/SDCCerr.c
7220 * support/Util/SDCCerr.h
7223 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7233 unsigned, but are signed by default
7234 * src/SDCCval.c (constVal): rearranged
7235 * src/SDCCval.c (valMod): preliminary fix
7236 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7279 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7280 * src/SDCCval.c (valDiv, valMod): fixed signdness
7281 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7282 signedness of modulo, left and right shift
7283 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

7745 the compiler with no port specified on command line, a default
7746 port is selected with the new macro DEFAULT_PORT which is
7747 defined in port.h, in setDefaultOptions() linkOptions is removed
7748 from initialization assignment, since now it is a set,
7749 parseCmdLine uses setParseWithComma for linkOptions, in

8818 2003-01-04 <johan AT balder>
8820 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8822 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8835 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8836 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8838 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8840 * in \sdcc\as\mcs51\ changed these files in order to create an
8841 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8842 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8843 following files to include the previous two files: aslink.dsp,
8844 Makefile.aslink, Makefile.bcc, and Makefile.in.
8846 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8847 .adb instead of .cdb
8849 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8851 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8852 value from option --iram-size.
8854 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8856 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8859 2002-09-18 <wiml AT hhhh.org>
8861 * SDCClrange.h: exposed setFromRange() and setToRange()
8862 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8863 packRegsForAccUse() (bug 542397)
8864 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8865 multiple times and emitting the fetch operations more than once
8866 added aopGetUsesAcc() function to allow binary operators to
8867 fetch their operands in the correct order; made genMinus() emit
8868 compact code for X = LITERAL - Y
8870 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8871 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8872 sprintf() in line 1267.
8874 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8875 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8878 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8879 Changes to aslink (All the changes are marked with 'JCF'):
8881 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8884 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8885 area BSEG. Also moves, if possible, the DATA area down into the internal
8886 ram so more space is available.
8888 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8891 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8892 not bytes. Function summary() which creates a memory usage summary
8893 file with extension .mem. Reports of overlaping stack and small stack
8894 size. If the space for the stack is less than 16 bytes aslink trows a
8897 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8898 the 8051. Option 'y' for memory summary output file.
8900 Changes to sdcc (All the changes are marked with 'JCF'):
8902 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8904 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8905 overlaying area for it (uses RegBankUsed[4]).
8907 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8908 bank zero as used by default. By default aslink locates the stack
8909 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8910 the creation of the .mem file. Delegates the allocation of data area
8911 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8912 the begining of the stack area to aslink.
8914 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8915 glue() in SDCCglue.c creates an area for it.
8917 2002-09-03 Borut Razem <borut.razem AT siol.net>
8918 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8919 sdcc/src/pic/glue.c:
8920 introduced atexit() handler for teporay files removal in case of
8921 errors, assertions, ...
8923 2002-08-29 Borut Razem <borut.razem AT siol.net>
8924 * sdcc/support/cpp2/auto-host_vc_in.h:
8925 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8926 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8927 Maybe there is a similar problem with BORLANDC? It should be checked!
8929 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8930 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8931 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8932 was not executed, and the compiler (cl) launched a warning:
8933 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8935 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8936 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8938 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8939 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8941 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8942 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8943 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8944 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8945 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8946 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8947 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8948 - added Release configuration in VS projects
8949 - review of compiler an linker options
8950 - VC .exe files are generated in bin_vc directory, not to interfere
8951 with binaries generated from other projects (cygwin, mingw, bcc ...)
8953 * sdcc/src/yacc.dsp: added
8955 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8956 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8957 and insert the version number definitions from .version
8959 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8961 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8962 added - genarate auto-host.h using auto-host_vc_in.h as template
8965 removed from CVS, generated automatically
8967 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8968 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8970 2002-08-11 Borut Razem <borut.razem AT siol.net>
8971 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8973 2002-08-10 Borut Razem <borut.razem AT siol.net>
8974 * src/SDCCmain.c (main):
8975 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8976 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8977 The consequence was that some temporary files were not removed.
8980 unification of code in functions tempfilename() and tempfile():
8981 function tempnam() is defined in Visual Studio 6.0 and .NET
8983 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8985 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8986 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8987 - removed compiler command line option /WX: Treats all warnings as errors
8988 - update a list of source files, included into the project
8990 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8991 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8992 changed project type to Generic Project so that can be correcly converted to VS.NET project
8994 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8996 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8998 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9000 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9001 added return 0 statements after assert() to make compiler happy
9003 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9004 added newline in the def file to keep MSC compiler satisfied
9006 * sdcc/src/z80/gen.c:
9007 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9008 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9009 - solved MSC error in function aopDump()
9011 * sdcc_vc.h: define PREFIX as "\\sdcc"
9013 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9014 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9017 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9018 - Rewrote the register banking algorithm.
9019 - Added pCode live-range analysis to registers (for now, only non-used and
9020 singly-used registers optimized away)
9022 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9024 * 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.
9026 2002-05-10 Scott Dattalo <scott AT dattalo.com>

9049 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9051 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9053 2002-03-28 Johan Knol <johan AT balder>
9055 * src/SDCCval.c: fixed bug #532436
9057 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9059 Added "char *Processor" field to the port structure.
9062 Added -p option. Allows port dependent processor to be specified.
9065 Initialized the new field char *Processor field to NULL in all ports
9068 Compiler generated registers for interrupt context saving
9069 were not getting allocated.
9071 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9074 Fixed left shift. Will promote the left side of a left shift
9075 if a) left shifting more than size of operand or b) when assigned
9076 to something size > size of left side
9078 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9080 tons of changes. Register allocation has been
9081 rewritten. Added customization for the various PICs. Flow
9082 analysis is restructured. ...
9088 Added. device.c is a PIC port hack to accomodate variations
9091 2002-03-13 Michael Hope <michaelh AT vroom>
9093 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9095 2002-03-04 johanknol <johanknol AT manik>
9097 * /src/SDCCval.c: fixed
9099 const unsigned char arr[][2] = { { 0, 1 } };
