1721 * src/z80/ralloc.c (z80_assignRegisters),
1723 * src/SDCCopt.c (eBBlockFromiCode, replaceRegEqv, killDeadCode),
1724 * src/SDCCcse.c (ifxOptimize, cseBBlock, cseAllBlocks),
1726 * src/SDCCdflow.c (computeDataFlow),
1728 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),

1732 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1733 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1734 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1735 immedDom() returning wrong block; probably fixes bug #1160833)
1737 2005-03-20 Borut Razem <borut.razem AT siol.net>
1739 * support/scripts/inc2h.pl: WIN32 port
1741 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1743 * device/lib/makefile.in: added abs.c and labs.c
1745 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1747 * device/include/stdint.h: added
1748 * device/lib/abs.c: added
1749 * device/lib/labs.c: added
1750 * device/include/stdlib.h: added abs() and labs() prototypes
1751 * device/lib/libsdcc.lib: added abs and labs
1752 * device/include/float.h,
1753 * device/lib/_fsmul.c,
1754 * device/lib/printf_fast.c,
1755 * device/lib/printf_tiny.c: updated comments
1757 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1759 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1762 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1764 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1765 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1767 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1769 * device/lib/printf_large.c: removed inline assembly for portability and
1770 readability. Use printf_fast if speed or size are more important.
1771 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1772 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1774 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1776 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1777 prevent compiler warning
1779 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1781 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1782 moved to level 0 and declared as static. Also they are explicit
1783 placed in access bank. This was necessery because some times they
1784 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1785 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1786 optimizations. Currently only compare to unsigned char is implemented,
1787 * src/pic16/gen.c: added fReturnIdx array,
1788 * (struct resolvedIfx) is moved to gen.h and made public,
1789 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1790 * (aopForSym): added an optimization to directly store in stack of
1791 the operand of a SEND iCode,
1792 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1793 but as registers instead (AOP_REG) using the fReturnIdx array,
1794 * (pic16_freeAsmop): remove the freed register from the
1795 _G.sregsAlloc field,
1796 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1797 a compare of 'WREG',
1798 * (pic16_popGetTempRegCond): changed function prototype, now
1799 function takes also a bitVector argument v which holds the current
1800 set of registers that are allocated for stack access by aopForSym,
1801 registers allocated in aopForSym for accessing stack symbols are not
1802 any more part of the functions usedRegs field,
1803 * (genCall): some times aopOp is called for a stack variable to be
1804 send, aopForSym might perform the push, if this is true make sure
1805 that genCall doesn't push the variable twice by testing _G.resDirect,
1806 * (genFunction): changed testing for unspecified interrupt number
1807 from 256 to INTNO_UNSPEC,
1808 * modified selection scheme of frame pointer generation. Previously
1809 if function did use local registers a frame pointer was generated,
1810 now a frame pointer is generated only if function has arguments
1811 (that need PLUSW2 register access), or has stack arguments, or the
1812 compiler is not instructed to omit the frame pointer,
1813 * (genEndFunction): before restoring local registers that were saved
1814 in the function preamble, also restore the registers that *might*
1815 have been allocated for stack access,
1816 * (genRet): removed some old comments,
1817 * (genCmp, the active (RN's) version): added a call to the
1818 pic16_genCmp_special function to perform the compare with a more
1819 robust and optimized way,
1820 * (genInline): a feature has been added in inline code generation,
1821 which allows a wildcard variable substitution when writing inline
1822 assembly. Code is incomplete and experimental therefore undocumented,
1823 * (genCast): changed order of aopOp for result and right to allow
1824 aopForSym to directly load the result if possible,
1825 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1826 perform an optimized compare on some selected special occasions,
1827 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1828 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1829 generate an IVT any more,
1830 * src/pic16/main.c (pic16_optionsTable): added command line option
1832 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1833 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1835 * src/pic16/NOTES: Raphael Neider added in list of active developers
1836 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1837 jumptable_end to prevent bug #,
1838 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1839 inCond and outCond fields,
1840 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1841 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1842 turn off register spilling,
1843 * (packRegsForOneUse): synced with other ports' versions although it
1844 is not used currently,
1845 * (pic16_packRegisters): added an optimization while reading
1846 structure bitfields, some registers may be saved (malloc code is
1847 decreased by 80 bytes)
1849 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1851 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1852 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1853 this can be optimized more?
1855 2005-03-10 Raphael Neider <rneider AT web.de>
1857 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1858 genNearPointerGet): (hopefully) fixed access to bitfields via
1859 pointers (p->bitN = x; and x = p->bitN; failed)
1861 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2529 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2531 * added libc directory. The current version of LibC contains string
2532 functions, ctype functions and macros and some functions of the
2533 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2534 be extensively tested in the future. Standard disclaimer here.
2535 Library is not automatically build yet. But one can build it by

2547 * (pic16_storeForReturn): optimized return of 0,
2548 * (genCmp): experimental code for new genCmp which uses PIC18's
2549 special compare&skip instructions. Initial tests fail some times
2550 with variables grater than 1 byte in size, so new code is disabled,
2551 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2553 * (genCast): began a fix to optimize the casting of a bit to another
2554 bit, now assigning a bitfield to another bitfield will fail, sorry,

2563 and 1 for banking instruction,
2564 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2565 caused stop processing pCodes after a inline assembly block,
2566 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2568 registers when it shouldn't,
2569 * src/pic16/ralloc.c (allocReg): add preliminary support for
2570 supporting a limited set of temporary registers,
2572 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2578 (genFunction): optimize RECEIVE iCodes in reentrant functions
2580 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2582 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5577 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5579 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5580 loaded with the linker search paths (-L arguments) and the libraries
5581 to be linked with the current source (-l arguments). Changes
5582 currently will affect only the pic16 port.
5583 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5584 include path the port specific paths and port specific libraries,
5585 * gplink command now contains the $3 argument,
5586 * src/pic16/device.h,
5587 * src/pic16/device.c,: structure PIC_device is made public and
5588 renamed to PIC16_device, the same for variable Pics which is renamed

5603 Documenting changes from previous commits.
5604 * configure.in (version 1.56),
5605 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5606 when generating output files to configure the pic16 library,
5607 but now I've commented it out, since gputils aren't installed in the
5608 SF compile farm, so library won't compile
5610 * device/lib/Makefile.in (version 1.56): initially I've added in
5611 target 'all' the prerequestive 'model-pic16' so it compiled the
5612 pic16 library, but now I've commented it out for the same reasons
5614 * added targets 'model-pic16' and 'objects-pic16' to compile the
5616 * added target 'port-specific-objects-pic16' to handle the
5617 generated libraries and copy them into the build/ directory
5618 * added target 'clean-intermediate-pic16' to clean intermediate
5619 files into pic16 directory
5620 * in target 'installdirs' added line to create directory pic16 in
5621 the installation path
5623 * device/include/Makefile.in (version 1.11): in target 'install'
5624 added lines to copy all header files to installation path,
5625 * in target 'installdirs' added line create directory for pic16
5626 headers in the installation path

5642 option so that it actually works. Made it specific to the z80, since
5643 the gbz80 doesn't have these kinds of I/O ports.
5645 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5647 * device/include/z180.h,

5671 via literal number. The symbol is placed in the corresponding
5672 position of the data ram
5673 * (pic16_dump_section): relocatable and absolute uninitialized
5674 data are now emitted in sorted order to reduce section naming,
5675 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5676 weren't marked as being in the access bank,
5678 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5680 Added portion of GNU PIC Library under the directory
5681 device/include/pic16 and device/lib/pic16. These files
5682 contain the declarations of SFRs for the PIC18Fxx2 devices.
5683 The directory is initialized via configure from toplevel.
5685 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5694 2004-01-12 Borut Razem <borut.razem AT siol.net>
5696 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
5697 doc/sdccman.lyx: upper case pragmas are deprecated
5699 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

5712 * doc/sdccman.lyx: Moved and added some sections, small changes
5713 all over. Telling LaTeX to be less strict with word spacing
5714 to better keep the right margin. Changed some notes about
5715 maintainance of the ports in section 3.2.1 - is it OK like this?
5717 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5719 SDCC source changes:
5720 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5755 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5757 * src/pic16/peeph.def: all peepholes with movff are commented out,
5758 because there is a problem in the pcode peep optimizer,
5759 * src/pic16/ralloc.c: the register allocator can now reuse local

5852 include information about variables allocated to the overlay
5855 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5857 * as/mcs51/lkmain.c: Help about -Y option

5869 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5871 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5872 (default behaviour).
5874 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5876 A python script to validate compiler diagnostic messages. It can be
5877 used to verify that sdcc complains about bad c source code and
5878 gives a good location of the error.
5879 * support/valdiag/Makefile,
5880 * support/valdiag/valdiag.py,
5881 * support/valdiag/tests/*

5897 around the header file.
5898 Bug reported from Jesus Calvino-Fraga
5900 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5902 * sdcc.spec: updated
5903 * device/include/Makefile.in: don't install CVS directories
5904 * device/lib/Makefile.in: added removal of CVS directories after install
5905 * doc/Makefile: fixed install, added local_icons
5906 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5907 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5908 * src/ds390/gen.c (genRightShift): fixed bug #870788
5909 * src/SDCCast.c (decorateType): fixed bug #870781
5911 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5913 PIC16 port related changes:
5914 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5915 added variable stackPos,
5917 * gen.c: genCall, assignResultValue: added support for
5918 pushing/retrieving function parameters to/from stack,
5919 genFunction,genEndFunction: setup stack frame for the
5921 genAddrOf: will be changed according to bug 863624
5923 * added files genutils.c and genutils.h which contain gen*
5924 debugged and optimised functions extracted from gen.c
5926 * glue.c: added variable 'externs' which holds extern symbols,
5927 pic16emitRegularMap: is modified to properly handle relocatable
5928 symbols under the new scheme,
5929 pic16createInterruptVect: is modified
5930 pic16printPublics: is modified to emit 'global' assembler directives,
5931 added pic16_printExterns to print extern symbols,
5932 pic16glue: initializes stack/frame pointer in the beginning of
5933 the assembly output. Temporary hack, will be corrected later,
5934 because gplink yet does not support stack and SDCC does not
5935 yet support a type of crt0.o object to create the final binary.
5937 * Removed many lines that contain 8051 legacy code.
5938 * The code is finally placed under a 'code' directive.
5939 * Added port specific options.
5941 * _process_pragma: simplified since now we do not need *special*
5942 include file to define SFR registers. But a separate header
5943 will be needed. This will be developed later.
5944 * _pic16_parseOptions: added, parses port specific options:
5945 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5946 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5947 --preplace-udata-with=
5949 * _pic16_setDefaultOptions: modified to initialize section names,
5950 but hack is temporarly out of order since it needs improvement.
5951 * _pic16_genAssemblerPreamble: configuration words are emitted by
5952 their address instead of their name. This part is incomplete and
5953 supports only the 18Fxx2 devices. Other devices will emit an error
5954 during assembly since they do not contain the same set of config
5956 * _pic16_genIVT: is modified,
5958 * pcode.c: added definitions for some hardware registers that are needed
5960 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5961 All PCI entries are updated. Now LFSR is supported.
5962 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5963 * added pic16_newpCodeOpLit2 to support instructions with
5964 two literal arguments
5965 * pic16_pCode2str: corrected code that emits assembler instructions
5966 with two literal operands and those that have an access bit modifier
5967 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5968 this fixes a bug which caused some labels to be lost, when an
5969 assembler directive was added, i.e. banksel,
5970 * pic16_FixRegisterBanking: improved logic that causes the insertion
5972 * InlineFunction: functions that are called once, are not any more
5973 inlined. This can be a port option in the future,
5975 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5977 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5978 hold the corresponding uninitialized symbols,
5979 * pic16_allocProcessorRegister: registers have explicit marked the
5981 * pic16_allocInternalRegister: registers are explicit marked as
5983 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5984 processing list, so bit registers were lost,
5987 * ralloc.h: added field 'accessBank' and original symbol operand
5988 in register definition,
5989 * removed the field isMapped from register definition,
5991 ** Several functions have been removed from various sources:
5992 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5993 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5994 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5995 pic16_assignRelocatableRegisters
5997 ** others have been introduced:
5998 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5999 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6001 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6003 * support/scripts/inc2h.pl: changed definition of BIT_AT
6004 to emit 'sbit at' instead of 'bit at'. This was a request.
6006 PIC16 port related preliminary changes:
6007 * gen.c: prefixed function popRegFromString with
6008 pic16_ and all references to it corrected
6009 * pcode.c: all pic16_pc_* hardware registers prefixed
6010 with underscore (_),
6011 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6012 * ralloc.c: newReg(): when register is REG_SFR then
6013 set address to rIdx,
6014 pic16_allocProcessorRegister(): marks register wasUsed=0
6015 pic16_writeUsedRegs(): added a call to assign processor
6016 registers via pic16_assignFixedRegisters
6018 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6020 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6021 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6022 variables in unused register banks. Also the SSEG is placed
6023 wherever there is enough space for it, and IDATA can be anywhere
6024 in internal RAM. For now compile using -Wl-Y[stack_size].
6025 The mem file is different for this option as well, since it
6026 makes no sense of talking about DSEG lenght.
6028 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6030 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6031 in certain cases, e.g. when ROM assignment, patch provided
6032 from Albert den Haan.
6034 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6177 * src/mcs51/peephole.def,
6178 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6179 (allows non-interrupt and interrupt code to safely compete for a resource

7057 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7058 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7077 A few small changes that speed up the peephole optimizer.
7081 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7083 Try to make the peephole optimizer smarter by maintaining
7084 an association between the assembly source code and the
7085 iCodes that originated them. Put this information to use
7086 with a new peephole rule condition "notVolatile" so that
7087 the rules can be aggressive yet still safe.
7092 * src/mcs51/peeph.def
7094 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7098 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7099 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7100 if the left or right operand symbols have the accuse flag set.
7102 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7104 Changed the type of the result of the ! (NOT) operator to char;
7105 previously it returned the same type as the source. This allows
7106 us to eliminate all the genFloatNot functions (all of its target
7107 implementations were very buggy) since !float can use the same
7110 * src/SDCCicode.c (ast2iCode): ! returns char

7119 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7120 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7121 during interrupts. Ensure WSAVE is located at a shared bank address.
7122 2. Fixed page selection in some places
7123 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7124 the registers name strings.
7125 4. Fixed "signed / unsigned compare" compiler warnings.
7126 5. The PIC port manages its own allocation of the general purpose
7127 registers, but makes no attempt to reuse them. As a result when
7128 compiling it soon runs out of general purpose registers. Some
7129 additional code was added to the files pcode.c and device.c to walk
7130 through the function call tree and rename the registers so that they
7140 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7147 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7149 Made bitfield a distinct type from bit so that bitfields
7150 convert as per ANSI C and bits retain their traditional
7151 boolean style behaviour. Implemented bitfield support in
7159 * src/ds390/gen.c: bit v bitfield split
7160 * src/z80/gen.c: New support for bitfields
7161 * support/regression/tests/bitfields.c: reenabled z80,
7164 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7166 Rules 246.x, 247.x relate to bitfields, the others speed up
7167 access to xdata mapped I/O devices.
7169 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7171 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7173 Cleaned up genPackBits and genUnpackBits and added two helper

7183 Fixed bug #748310 (pointer to function type mishandled when the
7184 function name is omitted). Also fixed a SIGSEGV when a function
7185 attribute (reentrant, etc) is used on a non-function or on a
7186 function but misplaced before the parameter list.

7215 Made the constant following the "interrupt" keyword optional. If
7216 omitted, the function will not automatically be given an entry
7217 in the interrupt vector table (similar to #pragma NOIV, but
7218 less syntacticly kludgy). The interrupt number is also now
7219 range checked. Also fixed a bug in the high order bit example
7226 * support/Util/SDCCerr.c
7227 * support/Util/SDCCerr.h
7230 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7240 unsigned, but are signed by default
7241 * src/SDCCval.c (constVal): rearranged
7242 * src/SDCCval.c (valMod): preliminary fix
7243 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7286 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7287 * src/SDCCval.c (valDiv, valMod): fixed signdness
7288 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7289 signedness of modulo, left and right shift
7290 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

7752 the compiler with no port specified on command line, a default
7753 port is selected with the new macro DEFAULT_PORT which is
7754 defined in port.h, in setDefaultOptions() linkOptions is removed
7755 from initialization assignment, since now it is a set,
7756 parseCmdLine uses setParseWithComma for linkOptions, in

8825 2003-01-04 <johan AT balder>
8827 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8829 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8830 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8832 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8833 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8842 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8843 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8845 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8847 * in \sdcc\as\mcs51\ changed these files in order to create an
8848 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8849 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8850 following files to include the previous two files: aslink.dsp,
8851 Makefile.aslink, Makefile.bcc, and Makefile.in.
8853 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8854 .adb instead of .cdb
8856 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8858 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8859 value from option --iram-size.
8861 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8863 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8866 2002-09-18 <wiml AT hhhh.org>
8868 * SDCClrange.h: exposed setFromRange() and setToRange()
8869 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8870 packRegsForAccUse() (bug 542397)
8871 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8872 multiple times and emitting the fetch operations more than once
8873 added aopGetUsesAcc() function to allow binary operators to
8874 fetch their operands in the correct order; made genMinus() emit
8875 compact code for X = LITERAL - Y
8877 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8878 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8879 sprintf() in line 1267.
8881 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8882 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8885 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8886 Changes to aslink (All the changes are marked with 'JCF'):
8888 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8891 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8892 area BSEG. Also moves, if possible, the DATA area down into the internal
8893 ram so more space is available.
8895 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8898 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8899 not bytes. Function summary() which creates a memory usage summary
8900 file with extension .mem. Reports of overlaping stack and small stack
8901 size. If the space for the stack is less than 16 bytes aslink trows a
8904 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8905 the 8051. Option 'y' for memory summary output file.
8907 Changes to sdcc (All the changes are marked with 'JCF'):
8909 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8911 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8912 overlaying area for it (uses RegBankUsed[4]).
8914 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8915 bank zero as used by default. By default aslink locates the stack
8916 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8917 the creation of the .mem file. Delegates the allocation of data area
8918 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8919 the begining of the stack area to aslink.
8921 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8922 glue() in SDCCglue.c creates an area for it.
8924 2002-09-03 Borut Razem <borut.razem AT siol.net>
8925 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8926 sdcc/src/pic/glue.c:
8927 introduced atexit() handler for teporay files removal in case of
8928 errors, assertions, ...
8930 2002-08-29 Borut Razem <borut.razem AT siol.net>
8931 * sdcc/support/cpp2/auto-host_vc_in.h:
8932 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8933 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8934 Maybe there is a similar problem with BORLANDC? It should be checked!
8936 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8937 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8938 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8939 was not executed, and the compiler (cl) launched a warning:
8940 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8942 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8943 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8945 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8946 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8948 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8949 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8950 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8951 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8952 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8953 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8954 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8955 - added Release configuration in VS projects
8956 - review of compiler an linker options
8957 - VC .exe files are generated in bin_vc directory, not to interfere
8958 with binaries generated from other projects (cygwin, mingw, bcc ...)
8960 * sdcc/src/yacc.dsp: added
8962 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8963 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8964 and insert the version number definitions from .version
8966 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8968 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8969 added - genarate auto-host.h using auto-host_vc_in.h as template
8972 removed from CVS, generated automatically
8974 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8975 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8977 2002-08-11 Borut Razem <borut.razem AT siol.net>
8978 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8980 2002-08-10 Borut Razem <borut.razem AT siol.net>
8981 * src/SDCCmain.c (main):
8982 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8983 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8984 The consequence was that some temporary files were not removed.
8987 unification of code in functions tempfilename() and tempfile():
8988 function tempnam() is defined in Visual Studio 6.0 and .NET
8990 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8992 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8993 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8994 - removed compiler command line option /WX: Treats all warnings as errors
8995 - update a list of source files, included into the project
8997 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8998 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8999 changed project type to Generic Project so that can be correcly converted to VS.NET project
9001 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9003 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9005 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9007 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9008 added return 0 statements after assert() to make compiler happy
9010 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9011 added newline in the def file to keep MSC compiler satisfied
9013 * sdcc/src/z80/gen.c:
9014 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9015 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9016 - solved MSC error in function aopDump()
9018 * sdcc_vc.h: define PREFIX as "\\sdcc"
9020 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9021 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9023 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9024 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9025 - Rewrote the register banking algorithm.
9026 - Added pCode live-range analysis to registers (for now, only non-used and
9027 singly-used registers optimized away)
9029 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9031 * 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.
9033 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9034 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

9056 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9058 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9060 2002-03-28 Johan Knol <johan AT balder>
9062 * src/SDCCval.c: fixed bug #532436
9064 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9066 Added "char *Processor" field to the port structure.
9069 Added -p option. Allows port dependent processor to be specified.
9072 Initialized the new field char *Processor field to NULL in all ports
9075 Compiler generated registers for interrupt context saving
9076 were not getting allocated.
9078 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9081 Fixed left shift. Will promote the left side of a left shift
9082 if a) left shifting more than size of operand or b) when assigned
9083 to something size > size of left side
9085 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9087 tons of changes. Register allocation has been
9088 rewritten. Added customization for the various PICs. Flow
9089 analysis is restructured. ...
9095 Added. device.c is a PIC port hack to accomodate variations
9098 2002-03-13 Michael Hope <michaelh AT vroom>
9100 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9102 2002-03-04 johanknol <johanknol AT manik>
9104 * /src/SDCCval.c: fixed
9106 const unsigned char arr[][2] = { { 0, 1 } };
9107 t18.c:1: error: Initializer element is not constant
9109 2002-03-04 bela <bela AT manik>
9111 * /device/include/mcs51reg.h:
