1714 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1716 * src/port.h (struct PORT),

1742 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1743 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1744 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1745 immedDom() returning wrong block; probably fixes bug #1160833)
1747 2005-03-20 Borut Razem <borut.razem AT siol.net>
1749 * support/scripts/inc2h.pl: WIN32 port
1751 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1753 * device/lib/makefile.in: added abs.c and labs.c
1755 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1757 * device/include/stdint.h: added
1758 * device/lib/abs.c: added
1759 * device/lib/labs.c: added
1760 * device/include/stdlib.h: added abs() and labs() prototypes
1761 * device/lib/libsdcc.lib: added abs and labs
1762 * device/include/float.h,
1763 * device/lib/_fsmul.c,
1764 * device/lib/printf_fast.c,
1765 * device/lib/printf_tiny.c: updated comments
1767 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1769 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1772 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1774 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1775 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1777 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1779 * device/lib/printf_large.c: removed inline assembly for portability and
1780 readability. Use printf_fast if speed or size are more important.
1781 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1782 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1784 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1786 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1787 prevent compiler warning
1789 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1791 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1792 moved to level 0 and declared as static. Also they are explicit
1793 placed in access bank. This was necessery because some times they
1794 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1795 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1796 optimizations. Currently only compare to unsigned char is implemented,
1797 * src/pic16/gen.c: added fReturnIdx array,
1798 * (struct resolvedIfx) is moved to gen.h and made public,
1799 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1800 * (aopForSym): added an optimization to directly store in stack of
1801 the operand of a SEND iCode,
1802 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1803 but as registers instead (AOP_REG) using the fReturnIdx array,
1804 * (pic16_freeAsmop): remove the freed register from the
1805 _G.sregsAlloc field,
1806 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1807 a compare of 'WREG',
1808 * (pic16_popGetTempRegCond): changed function prototype, now
1809 function takes also a bitVector argument v which holds the current
1810 set of registers that are allocated for stack access by aopForSym,
1811 registers allocated in aopForSym for accessing stack symbols are not
1812 any more part of the functions usedRegs field,
1813 * (genCall): some times aopOp is called for a stack variable to be
1814 send, aopForSym might perform the push, if this is true make sure
1815 that genCall doesn't push the variable twice by testing _G.resDirect,
1816 * (genFunction): changed testing for unspecified interrupt number
1817 from 256 to INTNO_UNSPEC,
1818 * modified selection scheme of frame pointer generation. Previously
1819 if function did use local registers a frame pointer was generated,
1820 now a frame pointer is generated only if function has arguments
1821 (that need PLUSW2 register access), or has stack arguments, or the
1822 compiler is not instructed to omit the frame pointer,
1823 * (genEndFunction): before restoring local registers that were saved
1824 in the function preamble, also restore the registers that *might*
1825 have been allocated for stack access,
1826 * (genRet): removed some old comments,
1827 * (genCmp, the active (RN's) version): added a call to the
1828 pic16_genCmp_special function to perform the compare with a more
1829 robust and optimized way,
1830 * (genInline): a feature has been added in inline code generation,
1831 which allows a wildcard variable substitution when writing inline
1832 assembly. Code is incomplete and experimental therefore undocumented,
1833 * (genCast): changed order of aopOp for result and right to allow
1834 aopForSym to directly load the result if possible,
1835 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1836 perform an optimized compare on some selected special occasions,
1837 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1838 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1839 generate an IVT any more,
1840 * src/pic16/main.c (pic16_optionsTable): added command line option
1842 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1843 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1845 * src/pic16/NOTES: Raphael Neider added in list of active developers
1846 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1847 jumptable_end to prevent bug #,
1848 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1849 inCond and outCond fields,
1850 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1851 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1852 turn off register spilling,
1853 * (packRegsForOneUse): synced with other ports' versions although it
1854 is not used currently,
1855 * (pic16_packRegisters): added an optimization while reading
1856 structure bitfields, some registers may be saved (malloc code is
1857 decreased by 80 bytes)
1859 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1861 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1862 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1863 this can be optimized more?
1865 2005-03-10 Raphael Neider <rneider AT web.de>
1867 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1868 genNearPointerGet): (hopefully) fixed access to bitfields via
1869 pointers (p->bitN = x; and x = p->bitN; failed)
1871 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1873 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2059 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2060 this might fix SIGSEGVs on MinGW...

2504 generated for switch statements. For now you need to set the
2505 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2506 Now 4 algorithms for mcs51 jumptable generation are used:
2507 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2541 * added libc directory. The current version of LibC contains string
2542 functions, ctype functions and macros and some functions of the
2543 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2544 be extensively tested in the future. Standard disclaimer here.
2545 Library is not automatically build yet. But one can build it by

2557 * (pic16_storeForReturn): optimized return of 0,
2558 * (genCmp): experimental code for new genCmp which uses PIC18's
2559 special compare&skip instructions. Initial tests fail some times
2560 with variables grater than 1 byte in size, so new code is disabled,
2561 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2563 * (genCast): began a fix to optimize the casting of a bit to another
2564 bit, now assigning a bitfield to another bitfield will fail, sorry,

2573 and 1 for banking instruction,
2574 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2575 caused stop processing pCodes after a inline assembly block,
2576 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2578 registers when it shouldn't,
2579 * src/pic16/ralloc.c (allocReg): add preliminary support for
2580 supporting a limited set of temporary registers,
2582 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2584 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5587 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5589 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5590 loaded with the linker search paths (-L arguments) and the libraries
5591 to be linked with the current source (-l arguments). Changes
5592 currently will affect only the pic16 port.
5593 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5594 include path the port specific paths and port specific libraries,
5595 * gplink command now contains the $3 argument,
5596 * src/pic16/device.h,
5597 * src/pic16/device.c,: structure PIC_device is made public and
5598 renamed to PIC16_device, the same for variable Pics which is renamed

5613 Documenting changes from previous commits.
5614 * configure.in (version 1.56),
5615 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5616 when generating output files to configure the pic16 library,
5617 but now I've commented it out, since gputils aren't installed in the
5618 SF compile farm, so library won't compile
5620 * device/lib/Makefile.in (version 1.56): initially I've added in
5621 target 'all' the prerequestive 'model-pic16' so it compiled the
5622 pic16 library, but now I've commented it out for the same reasons
5624 * added targets 'model-pic16' and 'objects-pic16' to compile the
5626 * added target 'port-specific-objects-pic16' to handle the
5627 generated libraries and copy them into the build/ directory
5628 * added target 'clean-intermediate-pic16' to clean intermediate
5629 files into pic16 directory
5630 * in target 'installdirs' added line to create directory pic16 in
5631 the installation path
5633 * device/include/Makefile.in (version 1.11): in target 'install'
5634 added lines to copy all header files to installation path,
5635 * in target 'installdirs' added line create directory for pic16
5636 headers in the installation path

5651 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5652 option so that it actually works. Made it specific to the z80, since
5653 the gbz80 doesn't have these kinds of I/O ports.
5655 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5657 * device/include/z180.h,

5681 via literal number. The symbol is placed in the corresponding
5682 position of the data ram
5683 * (pic16_dump_section): relocatable and absolute uninitialized
5684 data are now emitted in sorted order to reduce section naming,
5685 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5686 weren't marked as being in the access bank,
5688 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5690 Added portion of GNU PIC Library under the directory
5691 device/include/pic16 and device/lib/pic16. These files
5692 contain the declarations of SFRs for the PIC18Fxx2 devices.
5693 The directory is initialized via configure from toplevel.
5695 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5722 * doc/sdccman.lyx: Moved and added some sections, small changes
5723 all over. Telling LaTeX to be less strict with word spacing
5724 to better keep the right margin. Changed some notes about
5725 maintainance of the ports in section 3.2.1 - is it OK like this?
5727 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5862 include information about variables allocated to the overlay
5865 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5867 * as/mcs51/lkmain.c: Help about -Y option

5879 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5881 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5882 (default behaviour).
5884 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5886 A python script to validate compiler diagnostic messages. It can be
5887 used to verify that sdcc complains about bad c source code and
5888 gives a good location of the error.
5889 * support/valdiag/Makefile,
5890 * support/valdiag/valdiag.py,
5891 * support/valdiag/tests/*
5893 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5895 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

5906 * src/common.h: added ifndef/define/endif macros
5907 around the header file.
5908 Bug reported from Jesus Calvino-Fraga
5910 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5912 * sdcc.spec: updated
5913 * device/include/Makefile.in: don't install CVS directories
5914 * device/lib/Makefile.in: added removal of CVS directories after install
5915 * doc/Makefile: fixed install, added local_icons
5916 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5917 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5918 * src/ds390/gen.c (genRightShift): fixed bug #870788
5919 * src/SDCCast.c (decorateType): fixed bug #870781
5921 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5923 PIC16 port related changes:
5924 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5925 added variable stackPos,
5927 * gen.c: genCall, assignResultValue: added support for
5928 pushing/retrieving function parameters to/from stack,
5929 genFunction,genEndFunction: setup stack frame for the
5931 genAddrOf: will be changed according to bug 863624
5933 * added files genutils.c and genutils.h which contain gen*
5934 debugged and optimised functions extracted from gen.c
5936 * glue.c: added variable 'externs' which holds extern symbols,
5937 pic16emitRegularMap: is modified to properly handle relocatable
5938 symbols under the new scheme,
5939 pic16createInterruptVect: is modified
5940 pic16printPublics: is modified to emit 'global' assembler directives,
5941 added pic16_printExterns to print extern symbols,
5942 pic16glue: initializes stack/frame pointer in the beginning of
5943 the assembly output. Temporary hack, will be corrected later,
5944 because gplink yet does not support stack and SDCC does not
5945 yet support a type of crt0.o object to create the final binary.
5947 * Removed many lines that contain 8051 legacy code.
5948 * The code is finally placed under a 'code' directive.
5949 * Added port specific options.
5951 * _process_pragma: simplified since now we do not need *special*
5952 include file to define SFR registers. But a separate header
5953 will be needed. This will be developed later.
5954 * _pic16_parseOptions: added, parses port specific options:
5955 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5956 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5957 --preplace-udata-with=
5959 * _pic16_setDefaultOptions: modified to initialize section names,
5960 but hack is temporarly out of order since it needs improvement.
5961 * _pic16_genAssemblerPreamble: configuration words are emitted by
5962 their address instead of their name. This part is incomplete and
5963 supports only the 18Fxx2 devices. Other devices will emit an error
5964 during assembly since they do not contain the same set of config
5966 * _pic16_genIVT: is modified,
5968 * pcode.c: added definitions for some hardware registers that are needed
5970 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5971 All PCI entries are updated. Now LFSR is supported.
5972 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5973 * added pic16_newpCodeOpLit2 to support instructions with
5974 two literal arguments
5975 * pic16_pCode2str: corrected code that emits assembler instructions
5976 with two literal operands and those that have an access bit modifier
5977 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5978 this fixes a bug which caused some labels to be lost, when an
5979 assembler directive was added, i.e. banksel,
5980 * pic16_FixRegisterBanking: improved logic that causes the insertion
5982 * InlineFunction: functions that are called once, are not any more
5983 inlined. This can be a port option in the future,
5985 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5987 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5988 hold the corresponding uninitialized symbols,
5989 * pic16_allocProcessorRegister: registers have explicit marked the
5991 * pic16_allocInternalRegister: registers are explicit marked as
5993 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5994 processing list, so bit registers were lost,
5997 * ralloc.h: added field 'accessBank' and original symbol operand
5998 in register definition,
5999 * removed the field isMapped from register definition,
6001 ** Several functions have been removed from various sources:
6002 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6003 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6004 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6005 pic16_assignRelocatableRegisters
6007 ** others have been introduced:
6008 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6009 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6011 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6013 * support/scripts/inc2h.pl: changed definition of BIT_AT
6014 to emit 'sbit at' instead of 'bit at'. This was a request.
6016 PIC16 port related preliminary changes:
6017 * gen.c: prefixed function popRegFromString with
6018 pic16_ and all references to it corrected
6019 * pcode.c: all pic16_pc_* hardware registers prefixed
6020 with underscore (_),
6021 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6022 * ralloc.c: newReg(): when register is REG_SFR then
6023 set address to rIdx,
6024 pic16_allocProcessorRegister(): marks register wasUsed=0
6025 pic16_writeUsedRegs(): added a call to assign processor
6026 registers via pic16_assignFixedRegisters
6028 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6030 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6031 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6032 variables in unused register banks. Also the SSEG is placed
6033 wherever there is enough space for it, and IDATA can be anywhere
6034 in internal RAM. For now compile using -Wl-Y[stack_size].
6035 The mem file is different for this option as well, since it
6036 makes no sense of talking about DSEG lenght.
6038 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6040 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6041 in certain cases, e.g. when ROM assignment, patch provided
6042 from Albert den Haan.
6044 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7067 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7068 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7069 type for bits was changed. It resulted in bit variables becoming

7087 A few small changes that speed up the peephole optimizer.
7091 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7093 Try to make the peephole optimizer smarter by maintaining
7094 an association between the assembly source code and the
7095 iCodes that originated them. Put this information to use
7096 with a new peephole rule condition "notVolatile" so that
7097 the rules can be aggressive yet still safe.
7102 * src/mcs51/peeph.def
7104 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7108 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7109 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7110 if the left or right operand symbols have the accuse flag set.
7112 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7114 Changed the type of the result of the ! (NOT) operator to char;
7115 previously it returned the same type as the source. This allows
7116 us to eliminate all the genFloatNot functions (all of its target
7117 implementations were very buggy) since !float can use the same
7120 * src/SDCCicode.c (ast2iCode): ! returns char

7129 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7130 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7131 during interrupts. Ensure WSAVE is located at a shared bank address.
7132 2. Fixed page selection in some places
7133 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7134 the registers name strings.
7135 4. Fixed "signed / unsigned compare" compiler warnings.
7136 5. The PIC port manages its own allocation of the general purpose
7137 registers, but makes no attempt to reuse them. As a result when
7138 compiling it soon runs out of general purpose registers. Some
7139 additional code was added to the files pcode.c and device.c to walk
7140 through the function call tree and rename the registers so that they
7150 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7151 genPlus() & genMinus() when the result is the same as left or right

7157 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7159 Made bitfield a distinct type from bit so that bitfields
7160 convert as per ANSI C and bits retain their traditional
7161 boolean style behaviour. Implemented bitfield support in
7169 * src/ds390/gen.c: bit v bitfield split
7170 * src/z80/gen.c: New support for bitfields
7171 * support/regression/tests/bitfields.c: reenabled z80,
7174 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7176 Rules 246.x, 247.x relate to bitfields, the others speed up
7177 access to xdata mapped I/O devices.
7179 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7181 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7183 Cleaned up genPackBits and genUnpackBits and added two helper

7185 for literal assignments in genPackBits (thanks to Frieder for
7191 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7193 Fixed bug #748310 (pointer to function type mishandled when the
7194 function name is omitted). Also fixed a SIGSEGV when a function
7195 attribute (reentrant, etc) is used on a non-function or on a
7196 function but misplaced before the parameter list.

7214 * src/SDCC.y: More bitfield related error checking
7216 * src/SDCCsymt.c (compStructSize): fixed bitfield offset calc
7217 * support/Util/SDCCerr.h,
7218 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs

7223 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7225 Made the constant following the "interrupt" keyword optional. If
7226 omitted, the function will not automatically be given an entry
7227 in the interrupt vector table (similar to #pragma NOIV, but
7228 less syntacticly kludgy). The interrupt number is also now
7229 range checked. Also fixed a bug in the high order bit example
7236 * support/Util/SDCCerr.c
7237 * support/Util/SDCCerr.h
7240 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7247 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7248 be re-activated by defining REDUCE_LITERALS)
7249 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7250 unsigned, but are signed by default
7251 * src/SDCCval.c (constVal): rearranged
7252 * src/SDCCval.c (valMod): preliminary fix
7253 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7296 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7297 * src/SDCCval.c (valDiv, valMod): fixed signdness
7298 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7299 signedness of modulo, left and right shift
7300 * support/Util/SDCCerr.c: added warning "integer overflow in expression"

7761 support for the PIc16 port in the ports table, when executing
7762 the compiler with no port specified on command line, a default
7763 port is selected with the new macro DEFAULT_PORT which is
7764 defined in port.h, in setDefaultOptions() linkOptions is removed
7765 from initialization assignment, since now it is a set,
7766 parseCmdLine uses setParseWithComma for linkOptions, in
7767 linkEdit() linkOptions are accessed with new function indexSet()
7768 which returns the i'th item of a set variable. See SDCCset.c, in
7769 linkEdit() when calling buildCmdLine(), added linkOptions as
7770 last argument. Now users can pass arguments to gplink via the

8835 2003-01-04 <johan AT balder>
8837 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8839 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8840 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8842 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8852 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8853 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8855 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8857 * in \sdcc\as\mcs51\ changed these files in order to create an
8858 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8859 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8860 following files to include the previous two files: aslink.dsp,
8861 Makefile.aslink, Makefile.bcc, and Makefile.in.
8863 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8864 .adb instead of .cdb
8866 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8868 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8869 value from option --iram-size.
8871 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8873 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8876 2002-09-18 <wiml AT hhhh.org>
8878 * SDCClrange.h: exposed setFromRange() and setToRange()
8879 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8880 packRegsForAccUse() (bug 542397)
8881 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8882 multiple times and emitting the fetch operations more than once
8883 added aopGetUsesAcc() function to allow binary operators to
8884 fetch their operands in the correct order; made genMinus() emit
8885 compact code for X = LITERAL - Y
8887 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8888 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8889 sprintf() in line 1267.
8891 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8892 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8895 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8896 Changes to aslink (All the changes are marked with 'JCF'):
8898 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8901 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8902 area BSEG. Also moves, if possible, the DATA area down into the internal
8903 ram so more space is available.
8905 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8908 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8909 not bytes. Function summary() which creates a memory usage summary
8910 file with extension .mem. Reports of overlaping stack and small stack
8911 size. If the space for the stack is less than 16 bytes aslink trows a
8914 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8915 the 8051. Option 'y' for memory summary output file.
8917 Changes to sdcc (All the changes are marked with 'JCF'):
8919 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8921 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8922 overlaying area for it (uses RegBankUsed[4]).
8924 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8925 bank zero as used by default. By default aslink locates the stack
8926 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8927 the creation of the .mem file. Delegates the allocation of data area
8928 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8929 the begining of the stack area to aslink.
8931 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8932 glue() in SDCCglue.c creates an area for it.
8934 2002-09-03 Borut Razem <borut.razem AT siol.net>
8935 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8936 sdcc/src/pic/glue.c:
8937 introduced atexit() handler for teporay files removal in case of
8938 errors, assertions, ...
8940 2002-08-29 Borut Razem <borut.razem AT siol.net>
8941 * sdcc/support/cpp2/auto-host_vc_in.h:
8942 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8943 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8944 Maybe there is a similar problem with BORLANDC? It should be checked!
8946 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8947 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8948 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8949 was not executed, and the compiler (cl) launched a warning:
8950 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8952 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8953 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8955 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8956 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8958 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8959 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8960 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8961 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8962 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8963 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8964 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8965 - added Release configuration in VS projects
8966 - review of compiler an linker options
8967 - VC .exe files are generated in bin_vc directory, not to interfere
8968 with binaries generated from other projects (cygwin, mingw, bcc ...)
8970 * sdcc/src/yacc.dsp: added
8972 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8973 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8974 and insert the version number definitions from .version
8976 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8978 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8979 added - genarate auto-host.h using auto-host_vc_in.h as template
8982 removed from CVS, generated automatically
8984 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8985 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8987 2002-08-11 Borut Razem <borut.razem AT siol.net>
8988 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8990 2002-08-10 Borut Razem <borut.razem AT siol.net>
8991 * src/SDCCmain.c (main):
8992 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8993 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8994 The consequence was that some temporary files were not removed.
8997 unification of code in functions tempfilename() and tempfile():
8998 function tempnam() is defined in Visual Studio 6.0 and .NET
9000 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9002 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9003 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9004 - removed compiler command line option /WX: Treats all warnings as errors
9005 - update a list of source files, included into the project
9007 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9008 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9009 changed project type to Generic Project so that can be correcly converted to VS.NET project
9011 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9013 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9015 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9017 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9018 added return 0 statements after assert() to make compiler happy
9020 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9021 added newline in the def file to keep MSC compiler satisfied
9023 * sdcc/src/z80/gen.c:
9024 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9025 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9026 - solved MSC error in function aopDump()
9028 * sdcc_vc.h: define PREFIX as "\\sdcc"
9030 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9031 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9033 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9034 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9035 - Rewrote the register banking algorithm.
9036 - Added pCode live-range analysis to registers (for now, only non-used and
9037 singly-used registers optimized away)
9039 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9041 * 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.
9043 2002-05-10 Scott Dattalo <scott AT dattalo.com>

9066 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9068 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9070 2002-03-28 Johan Knol <johan AT balder>
9072 * src/SDCCval.c: fixed bug #532436
9074 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9076 Added "char *Processor" field to the port structure.
9079 Added -p option. Allows port dependent processor to be specified.
9082 Initialized the new field char *Processor field to NULL in all ports
9085 Compiler generated registers for interrupt context saving
9086 were not getting allocated.
9088 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9091 Fixed left shift. Will promote the left side of a left shift
9092 if a) left shifting more than size of operand or b) when assigned
9093 to something size > size of left side
9095 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9097 tons of changes. Register allocation has been
9098 rewritten. Added customization for the various PICs. Flow
9099 analysis is restructured. ...
