1738 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1739 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1740 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1741 immedDom() returning wrong block; probably fixes bug #1160833)
1743 2005-03-20 Borut Razem <borut.razem AT siol.net>
1745 * support/scripts/inc2h.pl: WIN32 port
1747 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1749 * device/lib/makefile.in: added abs.c and labs.c
1751 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1753 * device/include/stdint.h: added
1754 * device/lib/abs.c: added
1755 * device/lib/labs.c: added
1756 * device/include/stdlib.h: added abs() and labs() prototypes
1757 * device/lib/libsdcc.lib: added abs and labs
1758 * device/include/float.h,
1759 * device/lib/_fsmul.c,
1760 * device/lib/printf_fast.c,

1763 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1765 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1768 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1770 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1771 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1773 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1775 * device/lib/printf_large.c: removed inline assembly for portability and
1776 readability. Use printf_fast if speed or size are more important.
1777 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1778 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1780 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1782 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1783 prevent compiler warning
1785 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1787 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1788 moved to level 0 and declared as static. Also they are explicit
1789 placed in access bank. This was necessery because some times they
1790 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1791 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1792 optimizations. Currently only compare to unsigned char is implemented,
1793 * src/pic16/gen.c: added fReturnIdx array,
1794 * (struct resolvedIfx) is moved to gen.h and made public,
1795 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1796 * (aopForSym): added an optimization to directly store in stack of
1797 the operand of a SEND iCode,
1798 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1799 but as registers instead (AOP_REG) using the fReturnIdx array,
1800 * (pic16_freeAsmop): remove the freed register from the
1801 _G.sregsAlloc field,
1802 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1803 a compare of 'WREG',
1804 * (pic16_popGetTempRegCond): changed function prototype, now
1805 function takes also a bitVector argument v which holds the current
1806 set of registers that are allocated for stack access by aopForSym,
1807 registers allocated in aopForSym for accessing stack symbols are not
1808 any more part of the functions usedRegs field,
1809 * (genCall): some times aopOp is called for a stack variable to be
1810 send, aopForSym might perform the push, if this is true make sure
1811 that genCall doesn't push the variable twice by testing _G.resDirect,
1812 * (genFunction): changed testing for unspecified interrupt number
1813 from 256 to INTNO_UNSPEC,
1814 * modified selection scheme of frame pointer generation. Previously
1815 if function did use local registers a frame pointer was generated,
1816 now a frame pointer is generated only if function has arguments
1817 (that need PLUSW2 register access), or has stack arguments, or the
1818 compiler is not instructed to omit the frame pointer,
1819 * (genEndFunction): before restoring local registers that were saved
1820 in the function preamble, also restore the registers that *might*
1821 have been allocated for stack access,
1822 * (genRet): removed some old comments,
1823 * (genCmp, the active (RN's) version): added a call to the
1824 pic16_genCmp_special function to perform the compare with a more
1825 robust and optimized way,
1826 * (genInline): a feature has been added in inline code generation,
1827 which allows a wildcard variable substitution when writing inline
1828 assembly. Code is incomplete and experimental therefore undocumented,
1829 * (genCast): changed order of aopOp for result and right to allow
1830 aopForSym to directly load the result if possible,
1831 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1832 perform an optimized compare on some selected special occasions,
1833 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1834 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1835 generate an IVT any more,
1836 * src/pic16/main.c (pic16_optionsTable): added command line option
1838 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1839 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1841 * src/pic16/NOTES: Raphael Neider added in list of active developers
1842 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1843 jumptable_end to prevent bug #,
1844 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1845 inCond and outCond fields,
1846 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1847 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1848 turn off register spilling,
1849 * (packRegsForOneUse): synced with other ports' versions although it
1850 is not used currently,
1851 * (pic16_packRegisters): added an optimization while reading
1852 structure bitfields, some registers may be saved (malloc code is
1853 decreased by 80 bytes)
1855 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1857 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1858 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1859 this can be optimized more?
1861 2005-03-10 Raphael Neider <rneider AT web.de>
1863 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1864 genNearPointerGet): (hopefully) fixed access to bitfields via
1865 pointers (p->bitN = x; and x = p->bitN; failed)
1867 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2055 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2056 this might fix SIGSEGVs on MinGW...

2144 * (genUminus): rewritten to for efficiency
2145 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
2146 used uninitialized in some cases)

2537 * added libc directory. The current version of LibC contains string
2538 functions, ctype functions and macros and some functions of the
2539 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2540 be extensively tested in the future. Standard disclaimer here.
2541 Library is not automatically build yet. But one can build it by

2553 * (pic16_storeForReturn): optimized return of 0,
2554 * (genCmp): experimental code for new genCmp which uses PIC18's
2555 special compare&skip instructions. Initial tests fail some times
2556 with variables grater than 1 byte in size, so new code is disabled,
2557 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2559 * (genCast): began a fix to optimize the casting of a bit to another
2560 bit, now assigning a bitfield to another bitfield will fail, sorry,

2569 and 1 for banking instruction,
2570 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2571 caused stop processing pCodes after a inline assembly block,
2572 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2574 registers when it shouldn't,
2575 * src/pic16/ralloc.c (allocReg): add preliminary support for
2576 supporting a limited set of temporary registers,
2578 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2584 (genFunction): optimize RECEIVE iCodes in reentrant functions
2586 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5583 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5585 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5586 loaded with the linker search paths (-L arguments) and the libraries
5587 to be linked with the current source (-l arguments). Changes
5588 currently will affect only the pic16 port.
5589 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5590 include path the port specific paths and port specific libraries,
5591 * gplink command now contains the $3 argument,
5592 * src/pic16/device.h,
5593 * src/pic16/device.c,: structure PIC_device is made public and
5594 renamed to PIC16_device, the same for variable Pics which is renamed

5609 Documenting changes from previous commits.
5610 * configure.in (version 1.56),
5611 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5612 when generating output files to configure the pic16 library,
5613 but now I've commented it out, since gputils aren't installed in the
5614 SF compile farm, so library won't compile
5616 * device/lib/Makefile.in (version 1.56): initially I've added in
5617 target 'all' the prerequestive 'model-pic16' so it compiled the
5618 pic16 library, but now I've commented it out for the same reasons
5620 * added targets 'model-pic16' and 'objects-pic16' to compile the
5622 * added target 'port-specific-objects-pic16' to handle the
5623 generated libraries and copy them into the build/ directory
5624 * added target 'clean-intermediate-pic16' to clean intermediate
5625 files into pic16 directory
5626 * in target 'installdirs' added line to create directory pic16 in
5627 the installation path
5629 * device/include/Makefile.in (version 1.11): in target 'install'
5630 added lines to copy all header files to installation path,
5631 * in target 'installdirs' added line create directory for pic16
5632 headers in the installation path

5647 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5648 option so that it actually works. Made it specific to the z80, since
5649 the gbz80 doesn't have these kinds of I/O ports.
5651 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5653 * device/include/z180.h,

5677 via literal number. The symbol is placed in the corresponding
5678 position of the data ram
5679 * (pic16_dump_section): relocatable and absolute uninitialized
5680 data are now emitted in sorted order to reduce section naming,
5681 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5682 weren't marked as being in the access bank,
5684 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5686 Added portion of GNU PIC Library under the directory
5687 device/include/pic16 and device/lib/pic16. These files
5688 contain the declarations of SFRs for the PIC18Fxx2 devices.
5689 The directory is initialized via configure from toplevel.
5691 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5716 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5718 * doc/sdccman.lyx: Moved and added some sections, small changes
5719 all over. Telling LaTeX to be less strict with word spacing
5720 to better keep the right margin. Changed some notes about
5721 maintainance of the ports in section 3.2.1 - is it OK like this?
5723 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5725 SDCC source changes:
5726 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5875 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5877 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5878 (default behaviour).
5880 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5882 A python script to validate compiler diagnostic messages. It can be
5883 used to verify that sdcc complains about bad c source code and
5884 gives a good location of the error.
5885 * support/valdiag/Makefile,
5886 * support/valdiag/valdiag.py,
5887 * support/valdiag/tests/*
5889 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5902 * src/common.h: added ifndef/define/endif macros
5903 around the header file.
5904 Bug reported from Jesus Calvino-Fraga
5906 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5908 * sdcc.spec: updated
5909 * device/include/Makefile.in: don't install CVS directories
5910 * device/lib/Makefile.in: added removal of CVS directories after install
5911 * doc/Makefile: fixed install, added local_icons
5912 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5913 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5914 * src/ds390/gen.c (genRightShift): fixed bug #870788
5915 * src/SDCCast.c (decorateType): fixed bug #870781
5917 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5919 PIC16 port related changes:
5920 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5921 added variable stackPos,
5923 * gen.c: genCall, assignResultValue: added support for
5924 pushing/retrieving function parameters to/from stack,
5925 genFunction,genEndFunction: setup stack frame for the
5927 genAddrOf: will be changed according to bug 863624
5929 * added files genutils.c and genutils.h which contain gen*
5930 debugged and optimised functions extracted from gen.c
5932 * glue.c: added variable 'externs' which holds extern symbols,
5933 pic16emitRegularMap: is modified to properly handle relocatable
5934 symbols under the new scheme,
5935 pic16createInterruptVect: is modified
5936 pic16printPublics: is modified to emit 'global' assembler directives,
5937 added pic16_printExterns to print extern symbols,
5938 pic16glue: initializes stack/frame pointer in the beginning of
5939 the assembly output. Temporary hack, will be corrected later,
5940 because gplink yet does not support stack and SDCC does not
5941 yet support a type of crt0.o object to create the final binary.
5943 * Removed many lines that contain 8051 legacy code.
5944 * The code is finally placed under a 'code' directive.
5945 * Added port specific options.
5947 * _process_pragma: simplified since now we do not need *special*
5948 include file to define SFR registers. But a separate header
5949 will be needed. This will be developed later.
5950 * _pic16_parseOptions: added, parses port specific options:
5951 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5952 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5953 --preplace-udata-with=
5955 * _pic16_setDefaultOptions: modified to initialize section names,
5956 but hack is temporarly out of order since it needs improvement.
5957 * _pic16_genAssemblerPreamble: configuration words are emitted by
5958 their address instead of their name. This part is incomplete and
5959 supports only the 18Fxx2 devices. Other devices will emit an error
5960 during assembly since they do not contain the same set of config
5962 * _pic16_genIVT: is modified,
5964 * pcode.c: added definitions for some hardware registers that are needed
5966 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5967 All PCI entries are updated. Now LFSR is supported.
5968 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5969 * added pic16_newpCodeOpLit2 to support instructions with
5970 two literal arguments
5971 * pic16_pCode2str: corrected code that emits assembler instructions
5972 with two literal operands and those that have an access bit modifier
5973 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5974 this fixes a bug which caused some labels to be lost, when an
5975 assembler directive was added, i.e. banksel,
5976 * pic16_FixRegisterBanking: improved logic that causes the insertion
5978 * InlineFunction: functions that are called once, are not any more
5979 inlined. This can be a port option in the future,
5981 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5983 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5984 hold the corresponding uninitialized symbols,
5985 * pic16_allocProcessorRegister: registers have explicit marked the
5987 * pic16_allocInternalRegister: registers are explicit marked as
5989 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5990 processing list, so bit registers were lost,
5993 * ralloc.h: added field 'accessBank' and original symbol operand
5994 in register definition,
5995 * removed the field isMapped from register definition,
5997 ** Several functions have been removed from various sources:
5998 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5999 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6000 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6001 pic16_assignRelocatableRegisters
6003 ** others have been introduced:
6004 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6005 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6007 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6009 * support/scripts/inc2h.pl: changed definition of BIT_AT
6010 to emit 'sbit at' instead of 'bit at'. This was a request.
6012 PIC16 port related preliminary changes:
6013 * gen.c: prefixed function popRegFromString with
6014 pic16_ and all references to it corrected
6015 * pcode.c: all pic16_pc_* hardware registers prefixed
6016 with underscore (_),
6017 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6018 * ralloc.c: newReg(): when register is REG_SFR then
6019 set address to rIdx,
6020 pic16_allocProcessorRegister(): marks register wasUsed=0
6021 pic16_writeUsedRegs(): added a call to assign processor
6022 registers via pic16_assignFixedRegisters
6024 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6026 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6027 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6028 variables in unused register banks. Also the SSEG is placed
6029 wherever there is enough space for it, and IDATA can be anywhere
6030 in internal RAM. For now compile using -Wl-Y[stack_size].
6031 The mem file is different for this option as well, since it
6032 makes no sense of talking about DSEG lenght.
6034 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6036 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6037 in certain cases, e.g. when ROM assignment, patch provided
6038 from Albert den Haan.
6040 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6183 * src/mcs51/peephole.def,
6184 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6185 (allows non-interrupt and interrupt code to safely compete for a resource

7063 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7064 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7083 A few small changes that speed up the peephole optimizer.
7087 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7089 Try to make the peephole optimizer smarter by maintaining
7090 an association between the assembly source code and the
7091 iCodes that originated them. Put this information to use
7092 with a new peephole rule condition "notVolatile" so that
7093 the rules can be aggressive yet still safe.
7098 * src/mcs51/peeph.def
7100 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7104 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7105 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7106 if the left or right operand symbols have the accuse flag set.
7108 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7110 Changed the type of the result of the ! (NOT) operator to char;
7111 previously it returned the same type as the source. This allows
7112 us to eliminate all the genFloatNot functions (all of its target
7113 implementations were very buggy) since !float can use the same
7116 * src/SDCCicode.c (ast2iCode): ! returns char

7125 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7126 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7127 during interrupts. Ensure WSAVE is located at a shared bank address.
7128 2. Fixed page selection in some places
7129 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7130 the registers name strings.
7131 4. Fixed "signed / unsigned compare" compiler warnings.
7132 5. The PIC port manages its own allocation of the general purpose
7133 registers, but makes no attempt to reuse them. As a result when
7134 compiling it soon runs out of general purpose registers. Some
7135 additional code was added to the files pcode.c and device.c to walk
7136 through the function call tree and rename the registers so that they
7146 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7147 genPlus() & genMinus() when the result is the same as left or right

7153 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7155 Made bitfield a distinct type from bit so that bitfields
7156 convert as per ANSI C and bits retain their traditional
7157 boolean style behaviour. Implemented bitfield support in
7165 * src/ds390/gen.c: bit v bitfield split
7166 * src/z80/gen.c: New support for bitfields
7167 * support/regression/tests/bitfields.c: reenabled z80,
7170 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7172 Rules 246.x, 247.x relate to bitfields, the others speed up
7173 access to xdata mapped I/O devices.
7175 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7177 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7179 Cleaned up genPackBits and genUnpackBits and added two helper

7189 Fixed bug #748310 (pointer to function type mishandled when the
7190 function name is omitted). Also fixed a SIGSEGV when a function
7191 attribute (reentrant, etc) is used on a non-function or on a
7192 function but misplaced before the parameter list.

7219 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7221 Made the constant following the "interrupt" keyword optional. If
7222 omitted, the function will not automatically be given an entry
7223 in the interrupt vector table (similar to #pragma NOIV, but
7224 less syntacticly kludgy). The interrupt number is also now
7225 range checked. Also fixed a bug in the high order bit example
7232 * support/Util/SDCCerr.c
7233 * support/Util/SDCCerr.h

7757 support for the PIc16 port in the ports table, when executing
7758 the compiler with no port specified on command line, a default
7759 port is selected with the new macro DEFAULT_PORT which is
7760 defined in port.h, in setDefaultOptions() linkOptions is removed
7761 from initialization assignment, since now it is a set,
7762 parseCmdLine uses setParseWithComma for linkOptions, in
7763 linkEdit() linkOptions are accessed with new function indexSet()
7764 which returns the i'th item of a set variable. See SDCCset.c, in
7765 linkEdit() when calling buildCmdLine(), added linkOptions as
7766 last argument. Now users can pass arguments to gplink via the

8848 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8849 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8851 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8853 * in \sdcc\as\mcs51\ changed these files in order to create an
8854 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8855 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8856 following files to include the previous two files: aslink.dsp,
8857 Makefile.aslink, Makefile.bcc, and Makefile.in.
8859 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8860 .adb instead of .cdb
8862 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8864 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8865 value from option --iram-size.
8867 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8869 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8872 2002-09-18 <wiml AT hhhh.org>
8874 * SDCClrange.h: exposed setFromRange() and setToRange()
8875 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8876 packRegsForAccUse() (bug 542397)
8877 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8878 multiple times and emitting the fetch operations more than once
8879 added aopGetUsesAcc() function to allow binary operators to
8880 fetch their operands in the correct order; made genMinus() emit
8881 compact code for X = LITERAL - Y
8883 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8884 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8885 sprintf() in line 1267.
8887 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8888 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8891 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8892 Changes to aslink (All the changes are marked with 'JCF'):
8894 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8897 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8898 area BSEG. Also moves, if possible, the DATA area down into the internal
8899 ram so more space is available.
8901 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8904 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8905 not bytes. Function summary() which creates a memory usage summary
8906 file with extension .mem. Reports of overlaping stack and small stack
8907 size. If the space for the stack is less than 16 bytes aslink trows a
8910 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8911 the 8051. Option 'y' for memory summary output file.
8913 Changes to sdcc (All the changes are marked with 'JCF'):
8915 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8917 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8918 overlaying area for it (uses RegBankUsed[4]).
8920 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8921 bank zero as used by default. By default aslink locates the stack
8922 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8923 the creation of the .mem file. Delegates the allocation of data area
8924 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8925 the begining of the stack area to aslink.
8927 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8928 glue() in SDCCglue.c creates an area for it.
8930 2002-09-03 Borut Razem <borut.razem AT siol.net>
8931 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8932 sdcc/src/pic/glue.c:
8933 introduced atexit() handler for teporay files removal in case of
8934 errors, assertions, ...
8936 2002-08-29 Borut Razem <borut.razem AT siol.net>
8937 * sdcc/support/cpp2/auto-host_vc_in.h:
8938 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8939 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8940 Maybe there is a similar problem with BORLANDC? It should be checked!
8942 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8943 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8944 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8945 was not executed, and the compiler (cl) launched a warning:
8946 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8948 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8949 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8951 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8952 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8954 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8955 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8956 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8957 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8958 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8959 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8960 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8961 - added Release configuration in VS projects
8962 - review of compiler an linker options
8963 - VC .exe files are generated in bin_vc directory, not to interfere
8964 with binaries generated from other projects (cygwin, mingw, bcc ...)
8966 * sdcc/src/yacc.dsp: added
8968 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8969 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8970 and insert the version number definitions from .version
8972 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8974 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8975 added - genarate auto-host.h using auto-host_vc_in.h as template
8978 removed from CVS, generated automatically
8980 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8981 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8983 2002-08-11 Borut Razem <borut.razem AT siol.net>
8984 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8986 2002-08-10 Borut Razem <borut.razem AT siol.net>
8987 * src/SDCCmain.c (main):
8988 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8989 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8990 The consequence was that some temporary files were not removed.
8993 unification of code in functions tempfilename() and tempfile():
8994 function tempnam() is defined in Visual Studio 6.0 and .NET
8996 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8998 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8999 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9000 - removed compiler command line option /WX: Treats all warnings as errors
9001 - update a list of source files, included into the project
9003 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9004 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9005 changed project type to Generic Project so that can be correcly converted to VS.NET project
9007 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9009 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9011 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9013 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9014 added return 0 statements after assert() to make compiler happy
9016 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9017 added newline in the def file to keep MSC compiler satisfied
9019 * sdcc/src/z80/gen.c:
9020 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9021 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9022 - solved MSC error in function aopDump()
9024 * sdcc_vc.h: define PREFIX as "\\sdcc"
9026 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9027 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9029 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9030 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9031 - Rewrote the register banking algorithm.
9032 - Added pCode live-range analysis to registers (for now, only non-used and
9033 singly-used registers optimized away)
9035 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9037 * 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.
9039 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9040 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9042 2002-04-22 Michael Hope <michaelh AT vroom>

9058 * src/z80/peeph.def: Added transpose redundent load rule.
9060 * src/z80/main.c: Added force callee saves for jaune.
9062 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9064 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9066 2002-03-28 Johan Knol <johan AT balder>
9068 * src/SDCCval.c: fixed bug #532436
9070 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9072 Added "char *Processor" field to the port structure.
9075 Added -p option. Allows port dependent processor to be specified.
9078 Initialized the new field char *Processor field to NULL in all ports
9081 Compiler generated registers for interrupt context saving
9082 were not getting allocated.
9084 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9087 Fixed left shift. Will promote the left side of a left shift
9088 if a) left shifting more than size of operand or b) when assigned
9089 to something size > size of left side
9091 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9093 tons of changes. Register allocation has been
9094 rewritten. Added customization for the various PICs. Flow
9095 analysis is restructured. ...
9101 Added. device.c is a PIC port hack to accomodate variations
9104 2002-03-13 Michael Hope <michaelh AT vroom>
9106 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9108 2002-03-04 johanknol <johanknol AT manik>
9110 * /src/SDCCval.c: fixed
9112 const unsigned char arr[][2] = { { 0, 1 } };
