1719 * src/SDCCcse.c (ifxOptimize, cseBBlock, cseAllBlocks),
1721 * src/SDCCdflow.c (computeDataFlow),
1723 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
1725 * src/SDCCcflow.c (*),
1727 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1728 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1729 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1730 immedDom() returning wrong block; probably fixes bug #1160833)
1732 2005-03-20 Borut Razem <borut.razem AT siol.net>
1734 * support/scripts/inc2h.pl: WIN32 port
1736 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1738 * device/lib/makefile.in: added abs.c and labs.c
1740 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1742 * device/include/stdint.h: added
1743 * device/lib/abs.c: added
1744 * device/lib/labs.c: added
1745 * device/include/stdlib.h: added abs() and labs() prototypes
1746 * device/lib/libsdcc.lib: added abs and labs
1747 * device/include/float.h,
1748 * device/lib/_fsmul.c,
1749 * device/lib/printf_fast.c,
1750 * device/lib/printf_tiny.c: updated comments
1752 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1754 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1757 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1759 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1760 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1762 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1764 * device/lib/printf_large.c: removed inline assembly for portability and
1765 readability. Use printf_fast if speed or size are more important.
1766 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1767 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1769 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1771 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1772 prevent compiler warning
1774 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1776 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1777 moved to level 0 and declared as static. Also they are explicit
1778 placed in access bank. This was necessery because some times they
1779 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1780 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1781 optimizations. Currently only compare to unsigned char is implemented,
1782 * src/pic16/gen.c: added fReturnIdx array,
1783 * (struct resolvedIfx) is moved to gen.h and made public,
1784 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1785 * (aopForSym): added an optimization to directly store in stack of
1786 the operand of a SEND iCode,
1787 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1788 but as registers instead (AOP_REG) using the fReturnIdx array,
1789 * (pic16_freeAsmop): remove the freed register from the
1790 _G.sregsAlloc field,
1791 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1792 a compare of 'WREG',
1793 * (pic16_popGetTempRegCond): changed function prototype, now
1794 function takes also a bitVector argument v which holds the current
1795 set of registers that are allocated for stack access by aopForSym,
1796 registers allocated in aopForSym for accessing stack symbols are not
1797 any more part of the functions usedRegs field,
1798 * (genCall): some times aopOp is called for a stack variable to be
1799 send, aopForSym might perform the push, if this is true make sure
1800 that genCall doesn't push the variable twice by testing _G.resDirect,
1801 * (genFunction): changed testing for unspecified interrupt number
1802 from 256 to INTNO_UNSPEC,
1803 * modified selection scheme of frame pointer generation. Previously
1804 if function did use local registers a frame pointer was generated,
1805 now a frame pointer is generated only if function has arguments
1806 (that need PLUSW2 register access), or has stack arguments, or the
1807 compiler is not instructed to omit the frame pointer,
1808 * (genEndFunction): before restoring local registers that were saved
1809 in the function preamble, also restore the registers that *might*
1810 have been allocated for stack access,
1811 * (genRet): removed some old comments,
1812 * (genCmp, the active (RN's) version): added a call to the
1813 pic16_genCmp_special function to perform the compare with a more
1814 robust and optimized way,
1815 * (genInline): a feature has been added in inline code generation,
1816 which allows a wildcard variable substitution when writing inline
1817 assembly. Code is incomplete and experimental therefore undocumented,
1818 * (genCast): changed order of aopOp for result and right to allow
1819 aopForSym to directly load the result if possible,
1820 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1821 perform an optimized compare on some selected special occasions,
1822 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1823 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1824 generate an IVT any more,
1825 * src/pic16/main.c (pic16_optionsTable): added command line option
1827 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1828 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1830 * src/pic16/NOTES: Raphael Neider added in list of active developers
1831 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1832 jumptable_end to prevent bug #,
1833 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1834 inCond and outCond fields,
1835 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1836 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1837 turn off register spilling,
1838 * (packRegsForOneUse): synced with other ports' versions although it
1839 is not used currently,
1840 * (pic16_packRegisters): added an optimization while reading
1841 structure bitfields, some registers may be saved (malloc code is
1842 decreased by 80 bytes)
1844 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1846 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1847 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1848 this can be optimized more?
1850 2005-03-10 Raphael Neider <rneider AT web.de>
1852 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1853 genNearPointerGet): (hopefully) fixed access to bitfields via
1854 pointers (p->bitN = x; and x = p->bitN; failed)

2490 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2491 Now 4 algorithms for mcs51 jumptable generation are used:
2492 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2524 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2526 * added libc directory. The current version of LibC contains string
2527 functions, ctype functions and macros and some functions of the
2528 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2529 be extensively tested in the future. Standard disclaimer here.
2530 Library is not automatically build yet. But one can build it by

2542 * (pic16_storeForReturn): optimized return of 0,
2543 * (genCmp): experimental code for new genCmp which uses PIC18's
2544 special compare&skip instructions. Initial tests fail some times
2545 with variables grater than 1 byte in size, so new code is disabled,
2546 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2548 * (genCast): began a fix to optimize the casting of a bit to another
2549 bit, now assigning a bitfield to another bitfield will fail, sorry,

2558 and 1 for banking instruction,
2559 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2560 caused stop processing pCodes after a inline assembly block,

2563 registers when it shouldn't,
2564 * src/pic16/ralloc.c (allocReg): add preliminary support for
2565 supporting a limited set of temporary registers,
2567 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2573 (genFunction): optimize RECEIVE iCodes in reentrant functions
2575 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5572 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5574 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5575 loaded with the linker search paths (-L arguments) and the libraries
5576 to be linked with the current source (-l arguments). Changes
5577 currently will affect only the pic16 port.
5578 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5579 include path the port specific paths and port specific libraries,
5580 * gplink command now contains the $3 argument,
5581 * src/pic16/device.h,
5582 * src/pic16/device.c,: structure PIC_device is made public and
5583 renamed to PIC16_device, the same for variable Pics which is renamed

5598 Documenting changes from previous commits.
5599 * configure.in (version 1.56),
5600 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5601 when generating output files to configure the pic16 library,
5602 but now I've commented it out, since gputils aren't installed in the
5603 SF compile farm, so library won't compile
5605 * device/lib/Makefile.in (version 1.56): initially I've added in
5606 target 'all' the prerequestive 'model-pic16' so it compiled the
5607 pic16 library, but now I've commented it out for the same reasons
5609 * added targets 'model-pic16' and 'objects-pic16' to compile the
5611 * added target 'port-specific-objects-pic16' to handle the
5612 generated libraries and copy them into the build/ directory
5613 * added target 'clean-intermediate-pic16' to clean intermediate
5614 files into pic16 directory
5615 * in target 'installdirs' added line to create directory pic16 in
5616 the installation path
5618 * device/include/Makefile.in (version 1.11): in target 'install'
5619 added lines to copy all header files to installation path,
5620 * in target 'installdirs' added line create directory for pic16
5621 headers in the installation path

5637 option so that it actually works. Made it specific to the z80, since
5638 the gbz80 doesn't have these kinds of I/O ports.
5640 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5642 * device/include/z180.h,

5666 via literal number. The symbol is placed in the corresponding
5667 position of the data ram
5668 * (pic16_dump_section): relocatable and absolute uninitialized
5669 data are now emitted in sorted order to reduce section naming,
5670 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5671 weren't marked as being in the access bank,
5673 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5675 Added portion of GNU PIC Library under the directory
5676 device/include/pic16 and device/lib/pic16. These files
5677 contain the declarations of SFRs for the PIC18Fxx2 devices.
5678 The directory is initialized via configure from toplevel.
5680 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5689 2004-01-12 Borut Razem <borut.razem AT siol.net>
5691 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
5692 doc/sdccman.lyx: upper case pragmas are deprecated
5694 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

5707 * doc/sdccman.lyx: Moved and added some sections, small changes
5708 all over. Telling LaTeX to be less strict with word spacing
5709 to better keep the right margin. Changed some notes about
5710 maintainance of the ports in section 3.2.1 - is it OK like this?
5712 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5714 SDCC source changes:
5715 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5750 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5752 * src/pic16/peeph.def: all peepholes with movff are commented out,
5753 because there is a problem in the pcode peep optimizer,
5754 * src/pic16/ralloc.c: the register allocator can now reuse local

5847 include information about variables allocated to the overlay
5850 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5852 * as/mcs51/lkmain.c: Help about -Y option

5864 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5866 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5867 (default behaviour).
5869 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5871 A python script to validate compiler diagnostic messages. It can be
5872 used to verify that sdcc complains about bad c source code and
5873 gives a good location of the error.
5874 * support/valdiag/Makefile,
5875 * support/valdiag/valdiag.py,
5876 * support/valdiag/tests/*

5891 * src/common.h: added ifndef/define/endif macros
5892 around the header file.
5893 Bug reported from Jesus Calvino-Fraga
5895 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5897 * sdcc.spec: updated
5898 * device/include/Makefile.in: don't install CVS directories
5899 * device/lib/Makefile.in: added removal of CVS directories after install
5900 * doc/Makefile: fixed install, added local_icons
5901 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5902 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5903 * src/ds390/gen.c (genRightShift): fixed bug #870788
5904 * src/SDCCast.c (decorateType): fixed bug #870781
5906 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5908 PIC16 port related changes:
5909 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5910 added variable stackPos,
5912 * gen.c: genCall, assignResultValue: added support for
5913 pushing/retrieving function parameters to/from stack,
5914 genFunction,genEndFunction: setup stack frame for the
5916 genAddrOf: will be changed according to bug 863624
5918 * added files genutils.c and genutils.h which contain gen*
5919 debugged and optimised functions extracted from gen.c
5921 * glue.c: added variable 'externs' which holds extern symbols,
5922 pic16emitRegularMap: is modified to properly handle relocatable
5923 symbols under the new scheme,
5924 pic16createInterruptVect: is modified
5925 pic16printPublics: is modified to emit 'global' assembler directives,
5926 added pic16_printExterns to print extern symbols,
5927 pic16glue: initializes stack/frame pointer in the beginning of
5928 the assembly output. Temporary hack, will be corrected later,
5929 because gplink yet does not support stack and SDCC does not
5930 yet support a type of crt0.o object to create the final binary.
5932 * Removed many lines that contain 8051 legacy code.
5933 * The code is finally placed under a 'code' directive.
5934 * Added port specific options.
5936 * _process_pragma: simplified since now we do not need *special*
5937 include file to define SFR registers. But a separate header
5938 will be needed. This will be developed later.
5939 * _pic16_parseOptions: added, parses port specific options:
5940 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5941 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5942 --preplace-udata-with=
5944 * _pic16_setDefaultOptions: modified to initialize section names,
5945 but hack is temporarly out of order since it needs improvement.
5946 * _pic16_genAssemblerPreamble: configuration words are emitted by
5947 their address instead of their name. This part is incomplete and
5948 supports only the 18Fxx2 devices. Other devices will emit an error
5949 during assembly since they do not contain the same set of config
5951 * _pic16_genIVT: is modified,
5953 * pcode.c: added definitions for some hardware registers that are needed
5955 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5956 All PCI entries are updated. Now LFSR is supported.
5957 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5958 * added pic16_newpCodeOpLit2 to support instructions with
5959 two literal arguments
5960 * pic16_pCode2str: corrected code that emits assembler instructions
5961 with two literal operands and those that have an access bit modifier
5962 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5963 this fixes a bug which caused some labels to be lost, when an
5964 assembler directive was added, i.e. banksel,
5965 * pic16_FixRegisterBanking: improved logic that causes the insertion
5967 * InlineFunction: functions that are called once, are not any more
5968 inlined. This can be a port option in the future,
5970 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5972 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5973 hold the corresponding uninitialized symbols,
5974 * pic16_allocProcessorRegister: registers have explicit marked the
5976 * pic16_allocInternalRegister: registers are explicit marked as
5978 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5979 processing list, so bit registers were lost,
5982 * ralloc.h: added field 'accessBank' and original symbol operand
5983 in register definition,
5984 * removed the field isMapped from register definition,
5986 ** Several functions have been removed from various sources:
5987 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5988 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5989 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5990 pic16_assignRelocatableRegisters
5992 ** others have been introduced:
5993 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5994 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5996 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5998 * support/scripts/inc2h.pl: changed definition of BIT_AT
5999 to emit 'sbit at' instead of 'bit at'. This was a request.
6001 PIC16 port related preliminary changes:
6002 * gen.c: prefixed function popRegFromString with
6003 pic16_ and all references to it corrected
6004 * pcode.c: all pic16_pc_* hardware registers prefixed
6005 with underscore (_),
6006 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6007 * ralloc.c: newReg(): when register is REG_SFR then
6008 set address to rIdx,
6009 pic16_allocProcessorRegister(): marks register wasUsed=0
6010 pic16_writeUsedRegs(): added a call to assign processor
6011 registers via pic16_assignFixedRegisters
6013 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6015 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6016 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6017 variables in unused register banks. Also the SSEG is placed
6018 wherever there is enough space for it, and IDATA can be anywhere
6019 in internal RAM. For now compile using -Wl-Y[stack_size].
6020 The mem file is different for this option as well, since it
6021 makes no sense of talking about DSEG lenght.
6023 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6025 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6026 in certain cases, e.g. when ROM assignment, patch provided
6027 from Albert den Haan.
6029 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6172 * src/mcs51/peephole.def,
6173 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6174 (allows non-interrupt and interrupt code to safely compete for a resource

7052 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7053 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7054 type for bits was changed. It resulted in bit variables becoming

7072 A few small changes that speed up the peephole optimizer.
7076 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7078 Try to make the peephole optimizer smarter by maintaining
7079 an association between the assembly source code and the
7080 iCodes that originated them. Put this information to use
7081 with a new peephole rule condition "notVolatile" so that
7082 the rules can be aggressive yet still safe.
7087 * src/mcs51/peeph.def
7089 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7093 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7094 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7095 if the left or right operand symbols have the accuse flag set.
7097 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7099 Changed the type of the result of the ! (NOT) operator to char;
7100 previously it returned the same type as the source. This allows
7101 us to eliminate all the genFloatNot functions (all of its target
7102 implementations were very buggy) since !float can use the same
7105 * src/SDCCicode.c (ast2iCode): ! returns char

7114 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7115 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7116 during interrupts. Ensure WSAVE is located at a shared bank address.
7117 2. Fixed page selection in some places
7118 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7119 the registers name strings.
7120 4. Fixed "signed / unsigned compare" compiler warnings.
7121 5. The PIC port manages its own allocation of the general purpose
7122 registers, but makes no attempt to reuse them. As a result when
7123 compiling it soon runs out of general purpose registers. Some
7124 additional code was added to the files pcode.c and device.c to walk
7125 through the function call tree and rename the registers so that they
7135 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7136 genPlus() & genMinus() when the result is the same as left or right

7142 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7144 Made bitfield a distinct type from bit so that bitfields
7145 convert as per ANSI C and bits retain their traditional
7146 boolean style behaviour. Implemented bitfield support in
7154 * src/ds390/gen.c: bit v bitfield split
7155 * src/z80/gen.c: New support for bitfields
7156 * support/regression/tests/bitfields.c: reenabled z80,
7159 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7161 Rules 246.x, 247.x relate to bitfields, the others speed up
7162 access to xdata mapped I/O devices.
7164 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7166 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7168 Cleaned up genPackBits and genUnpackBits and added two helper

7170 for literal assignments in genPackBits (thanks to Frieder for
7176 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7178 Fixed bug #748310 (pointer to function type mishandled when the
7179 function name is omitted). Also fixed a SIGSEGV when a function
7180 attribute (reentrant, etc) is used on a non-function or on a
7181 function but misplaced before the parameter list.

7210 Made the constant following the "interrupt" keyword optional. If
7211 omitted, the function will not automatically be given an entry
7212 in the interrupt vector table (similar to #pragma NOIV, but
7213 less syntacticly kludgy). The interrupt number is also now
7214 range checked. Also fixed a bug in the high order bit example
7221 * support/Util/SDCCerr.c
7222 * support/Util/SDCCerr.h
7225 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7235 unsigned, but are signed by default
7236 * src/SDCCval.c (constVal): rearranged
7237 * src/SDCCval.c (valMod): preliminary fix
7238 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7281 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7282 * src/SDCCval.c (valDiv, valMod): fixed signdness
7283 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7284 signedness of modulo, left and right shift
7285 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

7747 the compiler with no port specified on command line, a default
7748 port is selected with the new macro DEFAULT_PORT which is
7749 defined in port.h, in setDefaultOptions() linkOptions is removed
7750 from initialization assignment, since now it is a set,
7751 parseCmdLine uses setParseWithComma for linkOptions, in
7752 linkEdit() linkOptions are accessed with new function indexSet()
7753 which returns the i'th item of a set variable. See SDCCset.c, in

8820 2003-01-04 <johan AT balder>
8822 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8824 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8825 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8827 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8828 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8837 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8838 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8840 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8842 * in \sdcc\as\mcs51\ changed these files in order to create an
8843 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8844 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8845 following files to include the previous two files: aslink.dsp,
8846 Makefile.aslink, Makefile.bcc, and Makefile.in.
8848 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8849 .adb instead of .cdb
8851 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8853 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8854 value from option --iram-size.
8856 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8858 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8861 2002-09-18 <wiml AT hhhh.org>
8863 * SDCClrange.h: exposed setFromRange() and setToRange()
8864 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8865 packRegsForAccUse() (bug 542397)
8866 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8867 multiple times and emitting the fetch operations more than once
8868 added aopGetUsesAcc() function to allow binary operators to
8869 fetch their operands in the correct order; made genMinus() emit
8870 compact code for X = LITERAL - Y
8872 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8873 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8874 sprintf() in line 1267.
8876 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8877 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8880 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8881 Changes to aslink (All the changes are marked with 'JCF'):
8883 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8886 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8887 area BSEG. Also moves, if possible, the DATA area down into the internal
8888 ram so more space is available.
8890 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8893 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8894 not bytes. Function summary() which creates a memory usage summary
8895 file with extension .mem. Reports of overlaping stack and small stack
8896 size. If the space for the stack is less than 16 bytes aslink trows a
8899 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8900 the 8051. Option 'y' for memory summary output file.
8902 Changes to sdcc (All the changes are marked with 'JCF'):
8904 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8906 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8907 overlaying area for it (uses RegBankUsed[4]).
8909 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8910 bank zero as used by default. By default aslink locates the stack
8911 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8912 the creation of the .mem file. Delegates the allocation of data area
8913 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8914 the begining of the stack area to aslink.
8916 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8917 glue() in SDCCglue.c creates an area for it.
8919 2002-09-03 Borut Razem <borut.razem AT siol.net>
8920 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8921 sdcc/src/pic/glue.c:
8922 introduced atexit() handler for teporay files removal in case of
8923 errors, assertions, ...
8925 2002-08-29 Borut Razem <borut.razem AT siol.net>
8926 * sdcc/support/cpp2/auto-host_vc_in.h:
8927 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8928 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8929 Maybe there is a similar problem with BORLANDC? It should be checked!
8931 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8932 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8933 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8934 was not executed, and the compiler (cl) launched a warning:
8935 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8937 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8938 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8940 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8941 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8943 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8944 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8945 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8946 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8947 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8948 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8949 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8950 - added Release configuration in VS projects
8951 - review of compiler an linker options
8952 - VC .exe files are generated in bin_vc directory, not to interfere
8953 with binaries generated from other projects (cygwin, mingw, bcc ...)
8955 * sdcc/src/yacc.dsp: added
8957 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8958 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8959 and insert the version number definitions from .version
8961 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8963 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8964 added - genarate auto-host.h using auto-host_vc_in.h as template
8967 removed from CVS, generated automatically
8969 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8970 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8972 2002-08-11 Borut Razem <borut.razem AT siol.net>
8973 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8975 2002-08-10 Borut Razem <borut.razem AT siol.net>
8976 * src/SDCCmain.c (main):
8977 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8978 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8979 The consequence was that some temporary files were not removed.
8982 unification of code in functions tempfilename() and tempfile():
8983 function tempnam() is defined in Visual Studio 6.0 and .NET
8985 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8987 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8988 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8989 - removed compiler command line option /WX: Treats all warnings as errors
8990 - update a list of source files, included into the project
8992 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8993 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8994 changed project type to Generic Project so that can be correcly converted to VS.NET project
8996 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8998 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9000 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9002 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9003 added return 0 statements after assert() to make compiler happy
9005 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9006 added newline in the def file to keep MSC compiler satisfied
9008 * sdcc/src/z80/gen.c:
9009 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9010 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9011 - solved MSC error in function aopDump()
9013 * sdcc_vc.h: define PREFIX as "\\sdcc"
9015 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9016 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9018 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9019 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9020 - Rewrote the register banking algorithm.
9021 - Added pCode live-range analysis to registers (for now, only non-used and
9022 singly-used registers optimized away)
9024 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9026 * 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.
9028 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9029 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

9047 * src/z80/peeph.def: Added transpose redundent load rule.
9049 * src/z80/main.c: Added force callee saves for jaune.
9051 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9053 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9055 2002-03-28 Johan Knol <johan AT balder>
9057 * src/SDCCval.c: fixed bug #532436
9059 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9061 Added "char *Processor" field to the port structure.
9064 Added -p option. Allows port dependent processor to be specified.
9067 Initialized the new field char *Processor field to NULL in all ports
9070 Compiler generated registers for interrupt context saving
9071 were not getting allocated.
9073 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9076 Fixed left shift. Will promote the left side of a left shift
9077 if a) left shifting more than size of operand or b) when assigned
9078 to something size > size of left side
9080 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9082 tons of changes. Register allocation has been
9083 rewritten. Added customization for the various PICs. Flow
9084 analysis is restructured. ...
9090 Added. device.c is a PIC port hack to accomodate variations
9093 2002-03-13 Michael Hope <michaelh AT vroom>
9095 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9097 2002-03-04 johanknol <johanknol AT manik>
9099 * /src/SDCCval.c: fixed
9101 const unsigned char arr[][2] = { { 0, 1 } };
9102 t18.c:1: error: Initializer element is not constant
9104 2002-03-04 bela <bela AT manik>
9106 * /device/include/mcs51reg.h:
