1718 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1719 immedDom() returning wrong block; probably fixes bug #1160833)
1721 2005-03-20 Borut Razem <borut.razem AT siol.net>
1723 * support/scripts/inc2h.pl: WIN32 port
1725 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1727 * device/lib/makefile.in: added abs.c and labs.c
1729 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1731 * device/include/stdint.h: added
1732 * device/lib/abs.c: added
1733 * device/lib/labs.c: added
1734 * device/include/stdlib.h: added abs() and labs() prototypes
1735 * device/lib/libsdcc.lib: added abs and labs
1736 * device/include/float.h,
1737 * device/lib/_fsmul.c,
1738 * device/lib/printf_fast.c,
1739 * device/lib/printf_tiny.c: updated comments
1741 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1743 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1746 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1748 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1749 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1751 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1753 * device/lib/printf_large.c: removed inline assembly for portability and
1754 readability. Use printf_fast if speed or size are more important.
1755 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1756 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1758 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1760 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1761 prevent compiler warning
1763 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1765 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1766 moved to level 0 and declared as static. Also they are explicit
1767 placed in access bank. This was necessery because some times they
1768 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1769 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1770 optimizations. Currently only compare to unsigned char is implemented,
1771 * src/pic16/gen.c: added fReturnIdx array,
1772 * (struct resolvedIfx) is moved to gen.h and made public,
1773 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1774 * (aopForSym): added an optimization to directly store in stack of
1775 the operand of a SEND iCode,
1776 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1777 but as registers instead (AOP_REG) using the fReturnIdx array,
1778 * (pic16_freeAsmop): remove the freed register from the
1779 _G.sregsAlloc field,
1780 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1781 a compare of 'WREG',
1782 * (pic16_popGetTempRegCond): changed function prototype, now
1783 function takes also a bitVector argument v which holds the current
1784 set of registers that are allocated for stack access by aopForSym,
1785 registers allocated in aopForSym for accessing stack symbols are not
1786 any more part of the functions usedRegs field,
1787 * (genCall): some times aopOp is called for a stack variable to be
1788 send, aopForSym might perform the push, if this is true make sure
1789 that genCall doesn't push the variable twice by testing _G.resDirect,
1790 * (genFunction): changed testing for unspecified interrupt number
1791 from 256 to INTNO_UNSPEC,
1792 * modified selection scheme of frame pointer generation. Previously
1793 if function did use local registers a frame pointer was generated,
1794 now a frame pointer is generated only if function has arguments
1795 (that need PLUSW2 register access), or has stack arguments, or the
1796 compiler is not instructed to omit the frame pointer,
1797 * (genEndFunction): before restoring local registers that were saved
1798 in the function preamble, also restore the registers that *might*
1799 have been allocated for stack access,
1800 * (genRet): removed some old comments,
1801 * (genCmp, the active (RN's) version): added a call to the
1802 pic16_genCmp_special function to perform the compare with a more
1803 robust and optimized way,
1804 * (genInline): a feature has been added in inline code generation,
1805 which allows a wildcard variable substitution when writing inline
1806 assembly. Code is incomplete and experimental therefore undocumented,
1807 * (genCast): changed order of aopOp for result and right to allow
1808 aopForSym to directly load the result if possible,
1809 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1810 perform an optimized compare on some selected special occasions,
1811 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1812 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1813 generate an IVT any more,
1814 * src/pic16/main.c (pic16_optionsTable): added command line option
1816 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1817 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1819 * src/pic16/NOTES: Raphael Neider added in list of active developers
1820 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1821 jumptable_end to prevent bug #,
1822 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1823 inCond and outCond fields,
1824 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1825 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1826 turn off register spilling,
1827 * (packRegsForOneUse): synced with other ports' versions although it
1828 is not used currently,
1829 * (pic16_packRegisters): added an optimization while reading
1830 structure bitfields, some registers may be saved (malloc code is
1831 decreased by 80 bytes)
1833 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1835 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1836 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1837 this can be optimized more?
1839 2005-03-10 Raphael Neider <rneider AT web.de>
1841 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1842 genNearPointerGet): (hopefully) fixed access to bitfields via
1843 pointers (p->bitN = x; and x = p->bitN; failed)

2478 generated for switch statements. For now you need to set the
2479 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2480 Now 4 algorithms for mcs51 jumptable generation are used:
2481 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2513 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2515 * added libc directory. The current version of LibC contains string
2516 functions, ctype functions and macros and some functions of the
2517 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2518 be extensively tested in the future. Standard disclaimer here.
2519 Library is not automatically build yet. But one can build it by

2531 * (pic16_storeForReturn): optimized return of 0,
2532 * (genCmp): experimental code for new genCmp which uses PIC18's
2533 special compare&skip instructions. Initial tests fail some times
2534 with variables grater than 1 byte in size, so new code is disabled,
2535 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2537 * (genCast): began a fix to optimize the casting of a bit to another
2538 bit, now assigning a bitfield to another bitfield will fail, sorry,

2547 and 1 for banking instruction,
2548 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2549 caused stop processing pCodes after a inline assembly block,
2550 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2552 registers when it shouldn't,
2553 * src/pic16/ralloc.c (allocReg): add preliminary support for
2554 supporting a limited set of temporary registers,
2556 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2562 (genFunction): optimize RECEIVE iCodes in reentrant functions
2564 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2566 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2580 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2582 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5516 code / RAM are in the same page / bank. This means the linker can
5517 safely allocate code/RAM of separate ASM files to different pages/banks.
5518 * doc/sdccman.lyx: added Slade's tips

5561 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5563 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5564 loaded with the linker search paths (-L arguments) and the libraries
5565 to be linked with the current source (-l arguments). Changes
5566 currently will affect only the pic16 port.
5567 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5568 include path the port specific paths and port specific libraries,
5569 * gplink command now contains the $3 argument,
5570 * src/pic16/device.h,
5571 * src/pic16/device.c,: structure PIC_device is made public and
5572 renamed to PIC16_device, the same for variable Pics which is renamed

5587 Documenting changes from previous commits.
5588 * configure.in (version 1.56),
5589 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5590 when generating output files to configure the pic16 library,
5591 but now I've commented it out, since gputils aren't installed in the
5592 SF compile farm, so library won't compile
5594 * device/lib/Makefile.in (version 1.56): initially I've added in
5595 target 'all' the prerequestive 'model-pic16' so it compiled the
5596 pic16 library, but now I've commented it out for the same reasons
5598 * added targets 'model-pic16' and 'objects-pic16' to compile the
5600 * added target 'port-specific-objects-pic16' to handle the
5601 generated libraries and copy them into the build/ directory
5602 * added target 'clean-intermediate-pic16' to clean intermediate
5603 files into pic16 directory
5604 * in target 'installdirs' added line to create directory pic16 in
5605 the installation path
5607 * device/include/Makefile.in (version 1.11): in target 'install'
5608 added lines to copy all header files to installation path,
5609 * in target 'installdirs' added line create directory for pic16
5610 headers in the installation path

5625 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5626 option so that it actually works. Made it specific to the z80, since
5627 the gbz80 doesn't have these kinds of I/O ports.
5629 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5631 * device/include/z180.h,

5653 Mainly changes to support compilation of the device libraries
5654 * src/pic16/device.c: stack is allocated via symbol and not
5655 via literal number. The symbol is placed in the corresponding
5656 position of the data ram
5657 * (pic16_dump_section): relocatable and absolute uninitialized
5658 data are now emitted in sorted order to reduce section naming,
5659 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5660 weren't marked as being in the access bank,
5662 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5664 Added portion of GNU PIC Library under the directory
5665 device/include/pic16 and device/lib/pic16. These files
5666 contain the declarations of SFRs for the PIC18Fxx2 devices.
5667 The directory is initialized via configure from toplevel.
5669 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5671 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5696 * doc/sdccman.lyx: Moved and added some sections, small changes
5697 all over. Telling LaTeX to be less strict with word spacing
5698 to better keep the right margin. Changed some notes about
5699 maintainance of the ports in section 3.2.1 - is it OK like this?
5701 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5710 processor registers declared internally by the port are emitted in
5711 the translation as equates,
5712 * src/pic16/gen.c: inline code is passed unprocessed to the

5853 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5855 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5856 (default behaviour).
5858 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5860 A python script to validate compiler diagnostic messages. It can be
5861 used to verify that sdcc complains about bad c source code and
5862 gives a good location of the error.
5863 * support/valdiag/Makefile,
5864 * support/valdiag/valdiag.py,
5865 * support/valdiag/tests/*

5880 * src/common.h: added ifndef/define/endif macros
5881 around the header file.
5882 Bug reported from Jesus Calvino-Fraga
5884 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5886 * sdcc.spec: updated
5887 * device/include/Makefile.in: don't install CVS directories
5888 * device/lib/Makefile.in: added removal of CVS directories after install
5889 * doc/Makefile: fixed install, added local_icons
5890 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5891 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5892 * src/ds390/gen.c (genRightShift): fixed bug #870788
5893 * src/SDCCast.c (decorateType): fixed bug #870781
5895 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5897 PIC16 port related changes:
5898 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5899 added variable stackPos,
5901 * gen.c: genCall, assignResultValue: added support for
5902 pushing/retrieving function parameters to/from stack,
5903 genFunction,genEndFunction: setup stack frame for the
5905 genAddrOf: will be changed according to bug 863624
5907 * added files genutils.c and genutils.h which contain gen*
5908 debugged and optimised functions extracted from gen.c
5910 * glue.c: added variable 'externs' which holds extern symbols,
5911 pic16emitRegularMap: is modified to properly handle relocatable
5912 symbols under the new scheme,
5913 pic16createInterruptVect: is modified
5914 pic16printPublics: is modified to emit 'global' assembler directives,
5915 added pic16_printExterns to print extern symbols,
5916 pic16glue: initializes stack/frame pointer in the beginning of
5917 the assembly output. Temporary hack, will be corrected later,
5918 because gplink yet does not support stack and SDCC does not
5919 yet support a type of crt0.o object to create the final binary.
5921 * Removed many lines that contain 8051 legacy code.
5922 * The code is finally placed under a 'code' directive.
5923 * Added port specific options.
5925 * _process_pragma: simplified since now we do not need *special*
5926 include file to define SFR registers. But a separate header
5927 will be needed. This will be developed later.
5928 * _pic16_parseOptions: added, parses port specific options:
5929 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5930 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5931 --preplace-udata-with=
5933 * _pic16_setDefaultOptions: modified to initialize section names,
5934 but hack is temporarly out of order since it needs improvement.
5935 * _pic16_genAssemblerPreamble: configuration words are emitted by
5936 their address instead of their name. This part is incomplete and
5937 supports only the 18Fxx2 devices. Other devices will emit an error
5938 during assembly since they do not contain the same set of config
5940 * _pic16_genIVT: is modified,
5942 * pcode.c: added definitions for some hardware registers that are needed
5944 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5945 All PCI entries are updated. Now LFSR is supported.
5946 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5947 * added pic16_newpCodeOpLit2 to support instructions with
5948 two literal arguments
5949 * pic16_pCode2str: corrected code that emits assembler instructions
5950 with two literal operands and those that have an access bit modifier
5951 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5952 this fixes a bug which caused some labels to be lost, when an
5953 assembler directive was added, i.e. banksel,
5954 * pic16_FixRegisterBanking: improved logic that causes the insertion
5956 * InlineFunction: functions that are called once, are not any more
5957 inlined. This can be a port option in the future,
5959 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5961 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5962 hold the corresponding uninitialized symbols,
5963 * pic16_allocProcessorRegister: registers have explicit marked the
5965 * pic16_allocInternalRegister: registers are explicit marked as
5967 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5968 processing list, so bit registers were lost,
5971 * ralloc.h: added field 'accessBank' and original symbol operand
5972 in register definition,
5973 * removed the field isMapped from register definition,
5975 ** Several functions have been removed from various sources:
5976 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5977 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5978 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5979 pic16_assignRelocatableRegisters
5981 ** others have been introduced:
5982 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5983 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5985 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5987 * support/scripts/inc2h.pl: changed definition of BIT_AT
5988 to emit 'sbit at' instead of 'bit at'. This was a request.
5990 PIC16 port related preliminary changes:
5991 * gen.c: prefixed function popRegFromString with
5992 pic16_ and all references to it corrected
5993 * pcode.c: all pic16_pc_* hardware registers prefixed
5994 with underscore (_),
5995 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5996 * ralloc.c: newReg(): when register is REG_SFR then
5997 set address to rIdx,
5998 pic16_allocProcessorRegister(): marks register wasUsed=0
5999 pic16_writeUsedRegs(): added a call to assign processor
6000 registers via pic16_assignFixedRegisters
6002 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6004 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6005 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6006 variables in unused register banks. Also the SSEG is placed
6007 wherever there is enough space for it, and IDATA can be anywhere
6008 in internal RAM. For now compile using -Wl-Y[stack_size].
6009 The mem file is different for this option as well, since it
6010 makes no sense of talking about DSEG lenght.
6012 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6014 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6015 in certain cases, e.g. when ROM assignment, patch provided
6016 from Albert den Haan.
6018 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6159 xdata and data memory on startup. Set the environment variable
6160 SDCC_NOGENRAMCLEAR to disable this.
6161 * src/mcs51/peephole.def,
6162 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6163 (allows non-interrupt and interrupt code to safely compete for a resource
6164 without the non-interrupt code having to disable interrupts)
6166 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6174 multiply defined with mismatching "at" address.
6176 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6178 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
6179 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

6904 support for standard C idiom of memory mapped variables; for
6905 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6906 to xdata int at 0x1234 tempvar = 1.
6907 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6908 provided by Akiya ISHIDA

6924 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6926 Fixed bug #621531 (const & volatile confusion in the type chain).
6927 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7007 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7008 iCode properly now. Use getSize instead of nRegs since a & b
7009 aren't part of the nRegs tally.
7011 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7013 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7019 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7020 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7021 fetching of the pointer
7022 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7023 copied from genNearPointerSet()
7024 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7025 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7026 If they pop r0/r1 they must be called in the opposite order than aopOp().
7027 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7028 (resp. --stack-auto), prepared for --xstack

7039 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7041 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7042 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7043 type for bits was changed. It resulted in bit variables becoming
7044 global, which is not permitted in PIC 14 assembly output.
7046 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7048 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7061 A few small changes that speed up the peephole optimizer.
7065 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7067 Try to make the peephole optimizer smarter by maintaining
7068 an association between the assembly source code and the
7069 iCodes that originated them. Put this information to use
7070 with a new peephole rule condition "notVolatile" so that
7071 the rules can be aggressive yet still safe.
7076 * src/mcs51/peeph.def
7078 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7082 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7083 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7084 if the left or right operand symbols have the accuse flag set.
7086 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7088 Changed the type of the result of the ! (NOT) operator to char;
7089 previously it returned the same type as the source. This allows
7090 us to eliminate all the genFloatNot functions (all of its target
7091 implementations were very buggy) since !float can use the same
7094 * src/SDCCicode.c (ast2iCode): ! returns char

7101 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7103 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7104 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7105 during interrupts. Ensure WSAVE is located at a shared bank address.
7106 2. Fixed page selection in some places
7107 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7108 the registers name strings.
7109 4. Fixed "signed / unsigned compare" compiler warnings.
7110 5. The PIC port manages its own allocation of the general purpose
7111 registers, but makes no attempt to reuse them. As a result when
7112 compiling it soon runs out of general purpose registers. Some
7113 additional code was added to the files pcode.c and device.c to walk
7114 through the function call tree and rename the registers so that they
7124 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7125 genPlus() & genMinus() when the result is the same as left or right
7127 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7131 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7133 Made bitfield a distinct type from bit so that bitfields
7134 convert as per ANSI C and bits retain their traditional
7135 boolean style behaviour. Implemented bitfield support in
7143 * src/ds390/gen.c: bit v bitfield split
7144 * src/z80/gen.c: New support for bitfields
7145 * support/regression/tests/bitfields.c: reenabled z80,
7148 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7150 Rules 246.x, 247.x relate to bitfields, the others speed up
7151 access to xdata mapped I/O devices.
7153 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7155 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7157 Cleaned up genPackBits and genUnpackBits and added two helper
7158 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7159 for literal assignments in genPackBits (thanks to Frieder for
7165 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7167 Fixed bug #748310 (pointer to function type mishandled when the
7168 function name is omitted). Also fixed a SIGSEGV when a function
7169 attribute (reentrant, etc) is used on a non-function or on a
7170 function but misplaced before the parameter list.
7172 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7174 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7175 * support/Util/SDCCerr.h,
7176 * support/Util/SDCCerr.c: Added func attr misuse error msg
7178 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7180 Fixed bug #787649 by anonymous
7181 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

7197 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7199 Made the constant following the "interrupt" keyword optional. If
7200 omitted, the function will not automatically be given an entry
7201 in the interrupt vector table (similar to #pragma NOIV, but
7202 less syntacticly kludgy). The interrupt number is also now
7203 range checked. Also fixed a bug in the high order bit example

7732 * src/SDCCmain.c: linkOptions is changed to set *,
7733 added if/endif conditional macros to remove options help
7734 messages from optionsTable when a port is not configured, added
7735 support for the PIc16 port in the ports table, when executing
7736 the compiler with no port specified on command line, a default
7737 port is selected with the new macro DEFAULT_PORT which is
7738 defined in port.h, in setDefaultOptions() linkOptions is removed
7739 from initialization assignment, since now it is a set,
7740 parseCmdLine uses setParseWithComma for linkOptions, in
7741 linkEdit() linkOptions are accessed with new function indexSet()
7742 which returns the i'th item of a set variable. See SDCCset.c, in
7743 linkEdit() when calling buildCmdLine(), added linkOptions as
7744 last argument. Now users can pass arguments to gplink via the
7745 -Wl option, main() uses pic16glue() to glue up pic16 programs

7757 * src/pic16/glue.c: commented out some error producing lines
7758 * src/pic16/main.c: __config directives are commented out to stop
7759 gpasm complaining and test the linkage with gplink, _linkCmd and
7760 _asmCmd changed to be more gplink and gpasm friendly
7761 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7762 produced an error when parsed, peep rule 12 is added to utilize
7763 movff, but it is commented out since the pCode does not support
7764 yet a command with 2 address arguments

8803 * src/SDCCicode.c: fixed array add
8805 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8806 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8807 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8809 2003-01-04 <johan AT balder>
8811 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8813 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8814 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8816 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8817 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8823 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8824 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8826 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8827 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8829 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8831 * in \sdcc\as\mcs51\ changed these files in order to create an
8832 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8833 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8834 following files to include the previous two files: aslink.dsp,
8835 Makefile.aslink, Makefile.bcc, and Makefile.in.
8837 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8838 .adb instead of .cdb
8840 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8842 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8843 value from option --iram-size.
8845 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8847 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8850 2002-09-18 <wiml AT hhhh.org>
8852 * SDCClrange.h: exposed setFromRange() and setToRange()
8853 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8854 packRegsForAccUse() (bug 542397)
8855 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8856 multiple times and emitting the fetch operations more than once
8857 added aopGetUsesAcc() function to allow binary operators to
8858 fetch their operands in the correct order; made genMinus() emit
8859 compact code for X = LITERAL - Y
8861 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8862 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8863 sprintf() in line 1267.
8865 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8866 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8869 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8870 Changes to aslink (All the changes are marked with 'JCF'):
8872 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8875 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8876 area BSEG. Also moves, if possible, the DATA area down into the internal
8877 ram so more space is available.
8879 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8882 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8883 not bytes. Function summary() which creates a memory usage summary
8884 file with extension .mem. Reports of overlaping stack and small stack
8885 size. If the space for the stack is less than 16 bytes aslink trows a
8888 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8889 the 8051. Option 'y' for memory summary output file.
8891 Changes to sdcc (All the changes are marked with 'JCF'):
8893 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8895 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8896 overlaying area for it (uses RegBankUsed[4]).
8898 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8899 bank zero as used by default. By default aslink locates the stack
8900 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8901 the creation of the .mem file. Delegates the allocation of data area
8902 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8903 the begining of the stack area to aslink.
8905 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8906 glue() in SDCCglue.c creates an area for it.
8908 2002-09-03 Borut Razem <borut.razem AT siol.net>
8909 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8910 sdcc/src/pic/glue.c:
8911 introduced atexit() handler for teporay files removal in case of
8912 errors, assertions, ...
8914 2002-08-29 Borut Razem <borut.razem AT siol.net>
8915 * sdcc/support/cpp2/auto-host_vc_in.h:
8916 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8917 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8918 Maybe there is a similar problem with BORLANDC? It should be checked!
8920 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8921 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8922 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8923 was not executed, and the compiler (cl) launched a warning:
8924 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8926 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8927 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8929 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8930 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8932 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8933 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8934 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8935 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8936 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8937 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8938 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8939 - added Release configuration in VS projects
8940 - review of compiler an linker options
8941 - VC .exe files are generated in bin_vc directory, not to interfere
8942 with binaries generated from other projects (cygwin, mingw, bcc ...)
8944 * sdcc/src/yacc.dsp: added
8946 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8947 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8948 and insert the version number definitions from .version
8950 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8952 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8953 added - genarate auto-host.h using auto-host_vc_in.h as template
8956 removed from CVS, generated automatically
8958 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8959 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8961 2002-08-11 Borut Razem <borut.razem AT siol.net>
8962 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8964 2002-08-10 Borut Razem <borut.razem AT siol.net>
8965 * src/SDCCmain.c (main):
8966 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8967 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8968 The consequence was that some temporary files were not removed.
8971 unification of code in functions tempfilename() and tempfile():
8972 function tempnam() is defined in Visual Studio 6.0 and .NET
8974 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8976 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8977 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8978 - removed compiler command line option /WX: Treats all warnings as errors
8979 - update a list of source files, included into the project
8981 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8982 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8983 changed project type to Generic Project so that can be correcly converted to VS.NET project
8985 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8987 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8989 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8991 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8992 added return 0 statements after assert() to make compiler happy
8994 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8995 added newline in the def file to keep MSC compiler satisfied
8997 * sdcc/src/z80/gen.c:
8998 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8999 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9000 - solved MSC error in function aopDump()
9002 * sdcc_vc.h: define PREFIX as "\\sdcc"
9004 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9005 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9007 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9008 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9009 - Rewrote the register banking algorithm.
9010 - Added pCode live-range analysis to registers (for now, only non-used and
9011 singly-used registers optimized away)
9013 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9015 * 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.
9017 2002-05-10 Scott Dattalo <scott AT dattalo.com>

9040 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9042 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9044 2002-03-28 Johan Knol <johan AT balder>
9046 * src/SDCCval.c: fixed bug #532436
9048 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9050 Added "char *Processor" field to the port structure.
9053 Added -p option. Allows port dependent processor to be specified.
9056 Initialized the new field char *Processor field to NULL in all ports
9059 Compiler generated registers for interrupt context saving
9060 were not getting allocated.
9062 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9065 Fixed left shift. Will promote the left side of a left shift
9066 if a) left shifting more than size of operand or b) when assigned
9067 to something size > size of left side
9069 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9071 tons of changes. Register allocation has been
9072 rewritten. Added customization for the various PICs. Flow
9073 analysis is restructured. ...
9079 Added. device.c is a PIC port hack to accomodate variations
9082 2002-03-13 Michael Hope <michaelh AT vroom>
9084 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9086 2002-03-04 johanknol <johanknol AT manik>
9088 * /src/SDCCval.c: fixed
9090 const unsigned char arr[][2] = { { 0, 1 } };
9091 t18.c:1: error: Initializer element is not constant
9093 2002-03-04 bela <bela AT manik>
9095 * /device/include/mcs51reg.h:
9096 ds89c420 register definition update
9098 2002-03-03 <johan AT FRIJA>
9100 * support/Util/SDCCerr.c: did something, but don't no why anymore
9102 * support/regression/tests/bug-524691.c: made it a little less shy
