1734 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1735 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1736 immedDom() returning wrong block; probably fixes bug #1160833)
1738 2005-03-20 Borut Razem <borut.razem AT siol.net>
1740 * support/scripts/inc2h.pl: WIN32 port
1742 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1744 * device/lib/makefile.in: added abs.c and labs.c
1746 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1748 * device/include/stdint.h: added
1749 * device/lib/abs.c: added
1750 * device/lib/labs.c: added
1751 * device/include/stdlib.h: added abs() and labs() prototypes
1752 * device/lib/libsdcc.lib: added abs and labs
1753 * device/include/float.h,
1754 * device/lib/_fsmul.c,
1755 * device/lib/printf_fast.c,
1756 * device/lib/printf_tiny.c: updated comments
1758 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1760 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1763 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1765 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1766 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1768 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1770 * device/lib/printf_large.c: removed inline assembly for portability and
1771 readability. Use printf_fast if speed or size are more important.
1772 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1773 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1775 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1777 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1778 prevent compiler warning
1780 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1782 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1783 moved to level 0 and declared as static. Also they are explicit
1784 placed in access bank. This was necessery because some times they
1785 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1786 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1787 optimizations. Currently only compare to unsigned char is implemented,
1788 * src/pic16/gen.c: added fReturnIdx array,
1789 * (struct resolvedIfx) is moved to gen.h and made public,
1790 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1791 * (aopForSym): added an optimization to directly store in stack of
1792 the operand of a SEND iCode,
1793 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1794 but as registers instead (AOP_REG) using the fReturnIdx array,
1795 * (pic16_freeAsmop): remove the freed register from the
1796 _G.sregsAlloc field,
1797 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1798 a compare of 'WREG',
1799 * (pic16_popGetTempRegCond): changed function prototype, now
1800 function takes also a bitVector argument v which holds the current
1801 set of registers that are allocated for stack access by aopForSym,
1802 registers allocated in aopForSym for accessing stack symbols are not
1803 any more part of the functions usedRegs field,
1804 * (genCall): some times aopOp is called for a stack variable to be
1805 send, aopForSym might perform the push, if this is true make sure
1806 that genCall doesn't push the variable twice by testing _G.resDirect,
1807 * (genFunction): changed testing for unspecified interrupt number
1808 from 256 to INTNO_UNSPEC,
1809 * modified selection scheme of frame pointer generation. Previously
1810 if function did use local registers a frame pointer was generated,
1811 now a frame pointer is generated only if function has arguments
1812 (that need PLUSW2 register access), or has stack arguments, or the
1813 compiler is not instructed to omit the frame pointer,
1814 * (genEndFunction): before restoring local registers that were saved
1815 in the function preamble, also restore the registers that *might*
1816 have been allocated for stack access,
1817 * (genRet): removed some old comments,
1818 * (genCmp, the active (RN's) version): added a call to the
1819 pic16_genCmp_special function to perform the compare with a more
1820 robust and optimized way,
1821 * (genInline): a feature has been added in inline code generation,
1822 which allows a wildcard variable substitution when writing inline
1823 assembly. Code is incomplete and experimental therefore undocumented,
1824 * (genCast): changed order of aopOp for result and right to allow
1825 aopForSym to directly load the result if possible,
1826 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1827 perform an optimized compare on some selected special occasions,
1828 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1829 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1830 generate an IVT any more,
1831 * src/pic16/main.c (pic16_optionsTable): added command line option
1833 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1834 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1836 * src/pic16/NOTES: Raphael Neider added in list of active developers
1837 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1838 jumptable_end to prevent bug #,
1839 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1840 inCond and outCond fields,
1841 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1842 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1843 turn off register spilling,
1844 * (packRegsForOneUse): synced with other ports' versions although it
1845 is not used currently,
1846 * (pic16_packRegisters): added an optimization while reading
1847 structure bitfields, some registers may be saved (malloc code is
1848 decreased by 80 bytes)
1850 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1852 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1853 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1854 this can be optimized more?
1856 2005-03-10 Raphael Neider <rneider AT web.de>
1858 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1859 genNearPointerGet): (hopefully) fixed access to bitfields via
1860 pointers (p->bitN = x; and x = p->bitN; failed)
1862 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2530 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2532 * added libc directory. The current version of LibC contains string
2533 functions, ctype functions and macros and some functions of the
2534 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2535 be extensively tested in the future. Standard disclaimer here.
2536 Library is not automatically build yet. But one can build it by

2548 * (pic16_storeForReturn): optimized return of 0,
2549 * (genCmp): experimental code for new genCmp which uses PIC18's
2550 special compare&skip instructions. Initial tests fail some times
2551 with variables grater than 1 byte in size, so new code is disabled,
2552 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2554 * (genCast): began a fix to optimize the casting of a bit to another
2555 bit, now assigning a bitfield to another bitfield will fail, sorry,

2564 and 1 for banking instruction,
2565 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2566 caused stop processing pCodes after a inline assembly block,
2567 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2569 registers when it shouldn't,
2570 * src/pic16/ralloc.c (allocReg): add preliminary support for
2571 supporting a limited set of temporary registers,
2573 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2575 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2576 genDataPointerSet): ensure assignments always copy in MSB to LSB
2578 (loadRegFromAop): recognize CLRH optimization,
2579 (genFunction): optimize RECEIVE iCodes in reentrant functions
2581 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2583 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5578 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5580 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5581 loaded with the linker search paths (-L arguments) and the libraries
5582 to be linked with the current source (-l arguments). Changes
5583 currently will affect only the pic16 port.
5584 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5585 include path the port specific paths and port specific libraries,
5586 * gplink command now contains the $3 argument,
5587 * src/pic16/device.h,
5588 * src/pic16/device.c,: structure PIC_device is made public and
5589 renamed to PIC16_device, the same for variable Pics which is renamed

5604 Documenting changes from previous commits.
5605 * configure.in (version 1.56),
5606 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5607 when generating output files to configure the pic16 library,
5608 but now I've commented it out, since gputils aren't installed in the
5609 SF compile farm, so library won't compile
5611 * device/lib/Makefile.in (version 1.56): initially I've added in
5612 target 'all' the prerequestive 'model-pic16' so it compiled the
5613 pic16 library, but now I've commented it out for the same reasons
5615 * added targets 'model-pic16' and 'objects-pic16' to compile the
5617 * added target 'port-specific-objects-pic16' to handle the
5618 generated libraries and copy them into the build/ directory
5619 * added target 'clean-intermediate-pic16' to clean intermediate
5620 files into pic16 directory
5621 * in target 'installdirs' added line to create directory pic16 in
5622 the installation path
5624 * device/include/Makefile.in (version 1.11): in target 'install'
5625 added lines to copy all header files to installation path,
5626 * in target 'installdirs' added line create directory for pic16
5627 headers in the installation path

5642 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5643 option so that it actually works. Made it specific to the z80, since
5644 the gbz80 doesn't have these kinds of I/O ports.
5646 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5648 * device/include/z180.h,

5672 via literal number. The symbol is placed in the corresponding
5673 position of the data ram
5674 * (pic16_dump_section): relocatable and absolute uninitialized
5675 data are now emitted in sorted order to reduce section naming,
5676 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5677 weren't marked as being in the access bank,
5679 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5681 Added portion of GNU PIC Library under the directory
5682 device/include/pic16 and device/lib/pic16. These files
5683 contain the declarations of SFRs for the PIC18Fxx2 devices.
5684 The directory is initialized via configure from toplevel.
5686 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5711 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5713 * doc/sdccman.lyx: Moved and added some sections, small changes
5714 all over. Telling LaTeX to be less strict with word spacing
5715 to better keep the right margin. Changed some notes about
5716 maintainance of the ports in section 3.2.1 - is it OK like this?
5718 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5720 SDCC source changes:
5721 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5755 UPPER for immediate operands,
5756 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5758 * src/pic16/peeph.def: all peepholes with movff are commented out,
5759 because there is a problem in the pcode peep optimizer,
5760 * src/pic16/ralloc.c: the register allocator can now reuse local

5870 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5872 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5873 (default behaviour).
5875 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5877 A python script to validate compiler diagnostic messages. It can be
5878 used to verify that sdcc complains about bad c source code and
5879 gives a good location of the error.
5880 * support/valdiag/Makefile,
5881 * support/valdiag/valdiag.py,
5882 * support/valdiag/tests/*

5899 Bug reported from Jesus Calvino-Fraga
5901 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5903 * sdcc.spec: updated
5904 * device/include/Makefile.in: don't install CVS directories
5905 * device/lib/Makefile.in: added removal of CVS directories after install
5906 * doc/Makefile: fixed install, added local_icons
5907 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5908 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5909 * src/ds390/gen.c (genRightShift): fixed bug #870788
5910 * src/SDCCast.c (decorateType): fixed bug #870781
5912 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5914 PIC16 port related changes:
5915 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5916 added variable stackPos,
5918 * gen.c: genCall, assignResultValue: added support for
5919 pushing/retrieving function parameters to/from stack,
5920 genFunction,genEndFunction: setup stack frame for the
5922 genAddrOf: will be changed according to bug 863624
5924 * added files genutils.c and genutils.h which contain gen*
5925 debugged and optimised functions extracted from gen.c
5927 * glue.c: added variable 'externs' which holds extern symbols,
5928 pic16emitRegularMap: is modified to properly handle relocatable
5929 symbols under the new scheme,
5930 pic16createInterruptVect: is modified
5931 pic16printPublics: is modified to emit 'global' assembler directives,
5932 added pic16_printExterns to print extern symbols,
5933 pic16glue: initializes stack/frame pointer in the beginning of
5934 the assembly output. Temporary hack, will be corrected later,
5935 because gplink yet does not support stack and SDCC does not
5936 yet support a type of crt0.o object to create the final binary.
5938 * Removed many lines that contain 8051 legacy code.
5939 * The code is finally placed under a 'code' directive.
5940 * Added port specific options.
5942 * _process_pragma: simplified since now we do not need *special*
5943 include file to define SFR registers. But a separate header
5944 will be needed. This will be developed later.
5945 * _pic16_parseOptions: added, parses port specific options:
5946 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5947 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5948 --preplace-udata-with=
5950 * _pic16_setDefaultOptions: modified to initialize section names,
5951 but hack is temporarly out of order since it needs improvement.
5952 * _pic16_genAssemblerPreamble: configuration words are emitted by
5953 their address instead of their name. This part is incomplete and
5954 supports only the 18Fxx2 devices. Other devices will emit an error
5955 during assembly since they do not contain the same set of config
5957 * _pic16_genIVT: is modified,
5959 * pcode.c: added definitions for some hardware registers that are needed
5961 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5962 All PCI entries are updated. Now LFSR is supported.
5963 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5964 * added pic16_newpCodeOpLit2 to support instructions with
5965 two literal arguments
5966 * pic16_pCode2str: corrected code that emits assembler instructions
5967 with two literal operands and those that have an access bit modifier
5968 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5969 this fixes a bug which caused some labels to be lost, when an
5970 assembler directive was added, i.e. banksel,
5971 * pic16_FixRegisterBanking: improved logic that causes the insertion
5973 * InlineFunction: functions that are called once, are not any more
5974 inlined. This can be a port option in the future,
5976 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5978 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5979 hold the corresponding uninitialized symbols,
5980 * pic16_allocProcessorRegister: registers have explicit marked the
5982 * pic16_allocInternalRegister: registers are explicit marked as
5984 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5985 processing list, so bit registers were lost,
5988 * ralloc.h: added field 'accessBank' and original symbol operand
5989 in register definition,
5990 * removed the field isMapped from register definition,
5992 ** Several functions have been removed from various sources:
5993 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5994 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5995 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5996 pic16_assignRelocatableRegisters
5998 ** others have been introduced:
5999 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6000 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6002 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6004 * support/scripts/inc2h.pl: changed definition of BIT_AT
6005 to emit 'sbit at' instead of 'bit at'. This was a request.
6007 PIC16 port related preliminary changes:
6008 * gen.c: prefixed function popRegFromString with
6009 pic16_ and all references to it corrected
6010 * pcode.c: all pic16_pc_* hardware registers prefixed
6011 with underscore (_),
6012 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6013 * ralloc.c: newReg(): when register is REG_SFR then
6014 set address to rIdx,
6015 pic16_allocProcessorRegister(): marks register wasUsed=0
6016 pic16_writeUsedRegs(): added a call to assign processor
6017 registers via pic16_assignFixedRegisters
6019 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6021 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6022 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6023 variables in unused register banks. Also the SSEG is placed
6024 wherever there is enough space for it, and IDATA can be anywhere
6025 in internal RAM. For now compile using -Wl-Y[stack_size].
6026 The mem file is different for this option as well, since it
6027 makes no sense of talking about DSEG lenght.
6029 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6031 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6032 in certain cases, e.g. when ROM assignment, patch provided
6033 from Albert den Haan.
6035 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6178 * src/mcs51/peephole.def,
6179 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7058 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7059 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7060 type for bits was changed. It resulted in bit variables becoming

7078 A few small changes that speed up the peephole optimizer.
7082 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7084 Try to make the peephole optimizer smarter by maintaining
7085 an association between the assembly source code and the
7086 iCodes that originated them. Put this information to use
7087 with a new peephole rule condition "notVolatile" so that
7088 the rules can be aggressive yet still safe.
7093 * src/mcs51/peeph.def
7095 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7099 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7100 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7101 if the left or right operand symbols have the accuse flag set.
7103 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7105 Changed the type of the result of the ! (NOT) operator to char;
7106 previously it returned the same type as the source. This allows
7107 us to eliminate all the genFloatNot functions (all of its target
7108 implementations were very buggy) since !float can use the same
7111 * src/SDCCicode.c (ast2iCode): ! returns char

7120 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7121 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7122 during interrupts. Ensure WSAVE is located at a shared bank address.
7123 2. Fixed page selection in some places
7124 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7125 the registers name strings.
7126 4. Fixed "signed / unsigned compare" compiler warnings.
7127 5. The PIC port manages its own allocation of the general purpose
7128 registers, but makes no attempt to reuse them. As a result when
7129 compiling it soon runs out of general purpose registers. Some
7130 additional code was added to the files pcode.c and device.c to walk
7131 through the function call tree and rename the registers so that they
7141 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7142 genPlus() & genMinus() when the result is the same as left or right

7148 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7150 Made bitfield a distinct type from bit so that bitfields
7151 convert as per ANSI C and bits retain their traditional
7152 boolean style behaviour. Implemented bitfield support in
7160 * src/ds390/gen.c: bit v bitfield split
7161 * src/z80/gen.c: New support for bitfields
7162 * support/regression/tests/bitfields.c: reenabled z80,
7165 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7167 Rules 246.x, 247.x relate to bitfields, the others speed up
7168 access to xdata mapped I/O devices.
7170 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7172 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7174 Cleaned up genPackBits and genUnpackBits and added two helper

7184 Fixed bug #748310 (pointer to function type mishandled when the
7185 function name is omitted). Also fixed a SIGSEGV when a function
7186 attribute (reentrant, etc) is used on a non-function or on a
7187 function but misplaced before the parameter list.

7214 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7216 Made the constant following the "interrupt" keyword optional. If
7217 omitted, the function will not automatically be given an entry
7218 in the interrupt vector table (similar to #pragma NOIV, but
7219 less syntacticly kludgy). The interrupt number is also now
7220 range checked. Also fixed a bug in the high order bit example
7227 * support/Util/SDCCerr.c
7228 * support/Util/SDCCerr.h

7752 support for the PIc16 port in the ports table, when executing
7753 the compiler with no port specified on command line, a default
7754 port is selected with the new macro DEFAULT_PORT which is
7755 defined in port.h, in setDefaultOptions() linkOptions is removed
7756 from initialization assignment, since now it is a set,
7757 parseCmdLine uses setParseWithComma for linkOptions, in
7758 linkEdit() linkOptions are accessed with new function indexSet()
7759 which returns the i'th item of a set variable. See SDCCset.c, in

8826 2003-01-04 <johan AT balder>
8828 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8830 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8843 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8844 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8846 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8848 * in \sdcc\as\mcs51\ changed these files in order to create an
8849 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8850 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8851 following files to include the previous two files: aslink.dsp,
8852 Makefile.aslink, Makefile.bcc, and Makefile.in.
8854 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8855 .adb instead of .cdb
8857 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8859 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8860 value from option --iram-size.
8862 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8864 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8867 2002-09-18 <wiml AT hhhh.org>
8869 * SDCClrange.h: exposed setFromRange() and setToRange()
8870 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8871 packRegsForAccUse() (bug 542397)
8872 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8873 multiple times and emitting the fetch operations more than once
8874 added aopGetUsesAcc() function to allow binary operators to
8875 fetch their operands in the correct order; made genMinus() emit
8876 compact code for X = LITERAL - Y
8878 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8879 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8880 sprintf() in line 1267.
8882 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8883 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8886 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8887 Changes to aslink (All the changes are marked with 'JCF'):
8889 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8892 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8893 area BSEG. Also moves, if possible, the DATA area down into the internal
8894 ram so more space is available.
8896 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8899 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8900 not bytes. Function summary() which creates a memory usage summary
8901 file with extension .mem. Reports of overlaping stack and small stack
8902 size. If the space for the stack is less than 16 bytes aslink trows a
8905 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8906 the 8051. Option 'y' for memory summary output file.
8908 Changes to sdcc (All the changes are marked with 'JCF'):
8910 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8912 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8913 overlaying area for it (uses RegBankUsed[4]).
8915 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8916 bank zero as used by default. By default aslink locates the stack
8917 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8918 the creation of the .mem file. Delegates the allocation of data area
8919 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8920 the begining of the stack area to aslink.
8922 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8923 glue() in SDCCglue.c creates an area for it.
8925 2002-09-03 Borut Razem <borut.razem AT siol.net>
8926 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8927 sdcc/src/pic/glue.c:
8928 introduced atexit() handler for teporay files removal in case of
8929 errors, assertions, ...
8931 2002-08-29 Borut Razem <borut.razem AT siol.net>
8932 * sdcc/support/cpp2/auto-host_vc_in.h:
8933 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8934 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8935 Maybe there is a similar problem with BORLANDC? It should be checked!
8937 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8938 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8939 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8940 was not executed, and the compiler (cl) launched a warning:
8941 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8943 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8944 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8946 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8947 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8949 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8950 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8951 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8952 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8953 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8954 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8955 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8956 - added Release configuration in VS projects
8957 - review of compiler an linker options
8958 - VC .exe files are generated in bin_vc directory, not to interfere
8959 with binaries generated from other projects (cygwin, mingw, bcc ...)
8961 * sdcc/src/yacc.dsp: added
8963 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8964 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8965 and insert the version number definitions from .version
8967 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8969 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8970 added - genarate auto-host.h using auto-host_vc_in.h as template
8973 removed from CVS, generated automatically
8975 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8976 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8978 2002-08-11 Borut Razem <borut.razem AT siol.net>
8979 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8981 2002-08-10 Borut Razem <borut.razem AT siol.net>
8982 * src/SDCCmain.c (main):
8983 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8984 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8985 The consequence was that some temporary files were not removed.
8988 unification of code in functions tempfilename() and tempfile():
8989 function tempnam() is defined in Visual Studio 6.0 and .NET
8991 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8993 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8994 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8995 - removed compiler command line option /WX: Treats all warnings as errors
8996 - update a list of source files, included into the project
8998 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8999 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9000 changed project type to Generic Project so that can be correcly converted to VS.NET project
9002 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9004 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9006 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9008 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9009 added return 0 statements after assert() to make compiler happy
9011 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9012 added newline in the def file to keep MSC compiler satisfied
9014 * sdcc/src/z80/gen.c:
9015 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9016 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9017 - solved MSC error in function aopDump()
9019 * sdcc_vc.h: define PREFIX as "\\sdcc"
9021 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9022 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9024 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9025 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9026 - Rewrote the register banking algorithm.
9027 - Added pCode live-range analysis to registers (for now, only non-used and
9028 singly-used registers optimized away)
9030 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9032 * 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.
9034 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9035 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9037 2002-04-22 Michael Hope <michaelh AT vroom>

9053 * src/z80/peeph.def: Added transpose redundent load rule.
9055 * src/z80/main.c: Added force callee saves for jaune.
9057 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9059 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9061 2002-03-28 Johan Knol <johan AT balder>
9063 * src/SDCCval.c: fixed bug #532436
9065 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9067 Added "char *Processor" field to the port structure.
9070 Added -p option. Allows port dependent processor to be specified.
9073 Initialized the new field char *Processor field to NULL in all ports
9076 Compiler generated registers for interrupt context saving
9077 were not getting allocated.
9079 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9082 Fixed left shift. Will promote the left side of a left shift
9083 if a) left shifting more than size of operand or b) when assigned
9084 to something size > size of left side
9086 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9088 tons of changes. Register allocation has been
9089 rewritten. Added customization for the various PICs. Flow
9090 analysis is restructured. ...
9096 Added. device.c is a PIC port hack to accomodate variations
9099 2002-03-13 Michael Hope <michaelh AT vroom>
9101 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9103 2002-03-04 johanknol <johanknol AT manik>
9105 * /src/SDCCval.c: fixed
9107 const unsigned char arr[][2] = { { 0, 1 } };
