1721 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1722 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1723 immedDom() returning wrong block; probably fixes bug #1160833)
1725 2005-03-20 Borut Razem <borut.razem AT siol.net>
1727 * support/scripts/inc2h.pl: WIN32 port
1729 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1731 * device/lib/makefile.in: added abs.c and labs.c
1733 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1735 * device/include/stdint.h: added
1736 * device/lib/abs.c: added
1737 * device/lib/labs.c: added
1738 * device/include/stdlib.h: added abs() and labs() prototypes
1739 * device/lib/libsdcc.lib: added abs and labs
1740 * device/include/float.h,
1741 * device/lib/_fsmul.c,
1742 * device/lib/printf_fast.c,
1743 * device/lib/printf_tiny.c: updated comments
1745 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1747 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1750 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1752 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1753 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1755 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1757 * device/lib/printf_large.c: removed inline assembly for portability and
1758 readability. Use printf_fast if speed or size are more important.
1759 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1760 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1762 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1764 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1765 prevent compiler warning
1767 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1769 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1770 moved to level 0 and declared as static. Also they are explicit
1771 placed in access bank. This was necessery because some times they
1772 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1773 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1774 optimizations. Currently only compare to unsigned char is implemented,
1775 * src/pic16/gen.c: added fReturnIdx array,
1776 * (struct resolvedIfx) is moved to gen.h and made public,
1777 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1778 * (aopForSym): added an optimization to directly store in stack of
1779 the operand of a SEND iCode,
1780 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1781 but as registers instead (AOP_REG) using the fReturnIdx array,
1782 * (pic16_freeAsmop): remove the freed register from the
1783 _G.sregsAlloc field,
1784 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1785 a compare of 'WREG',
1786 * (pic16_popGetTempRegCond): changed function prototype, now
1787 function takes also a bitVector argument v which holds the current
1788 set of registers that are allocated for stack access by aopForSym,
1789 registers allocated in aopForSym for accessing stack symbols are not
1790 any more part of the functions usedRegs field,
1791 * (genCall): some times aopOp is called for a stack variable to be
1792 send, aopForSym might perform the push, if this is true make sure
1793 that genCall doesn't push the variable twice by testing _G.resDirect,
1794 * (genFunction): changed testing for unspecified interrupt number
1795 from 256 to INTNO_UNSPEC,
1796 * modified selection scheme of frame pointer generation. Previously
1797 if function did use local registers a frame pointer was generated,
1798 now a frame pointer is generated only if function has arguments
1799 (that need PLUSW2 register access), or has stack arguments, or the
1800 compiler is not instructed to omit the frame pointer,
1801 * (genEndFunction): before restoring local registers that were saved
1802 in the function preamble, also restore the registers that *might*
1803 have been allocated for stack access,
1804 * (genRet): removed some old comments,
1805 * (genCmp, the active (RN's) version): added a call to the
1806 pic16_genCmp_special function to perform the compare with a more
1807 robust and optimized way,
1808 * (genInline): a feature has been added in inline code generation,
1809 which allows a wildcard variable substitution when writing inline
1810 assembly. Code is incomplete and experimental therefore undocumented,
1811 * (genCast): changed order of aopOp for result and right to allow
1812 aopForSym to directly load the result if possible,
1813 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1814 perform an optimized compare on some selected special occasions,
1815 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1816 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1817 generate an IVT any more,
1818 * src/pic16/main.c (pic16_optionsTable): added command line option
1820 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1821 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1823 * src/pic16/NOTES: Raphael Neider added in list of active developers
1824 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1825 jumptable_end to prevent bug #,
1826 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1827 inCond and outCond fields,
1828 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1829 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1830 turn off register spilling,
1831 * (packRegsForOneUse): synced with other ports' versions although it
1832 is not used currently,
1833 * (pic16_packRegisters): added an optimization while reading
1834 structure bitfields, some registers may be saved (malloc code is
1835 decreased by 80 bytes)
1837 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1839 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1840 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1841 this can be optimized more?
1843 2005-03-10 Raphael Neider <rneider AT web.de>
1845 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1846 genNearPointerGet): (hopefully) fixed access to bitfields via
1847 pointers (p->bitN = x; and x = p->bitN; failed)
1849 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2482 generated for switch statements. For now you need to set the
2483 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2484 Now 4 algorithms for mcs51 jumptable generation are used:
2485 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2517 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2519 * added libc directory. The current version of LibC contains string
2520 functions, ctype functions and macros and some functions of the
2521 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2522 be extensively tested in the future. Standard disclaimer here.
2523 Library is not automatically build yet. But one can build it by
2524 invoking 'make' inside the libc directory.

2535 * (pic16_storeForReturn): optimized return of 0,
2536 * (genCmp): experimental code for new genCmp which uses PIC18's
2537 special compare&skip instructions. Initial tests fail some times
2538 with variables grater than 1 byte in size, so new code is disabled,
2539 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2541 * (genCast): began a fix to optimize the casting of a bit to another
2542 bit, now assigning a bitfield to another bitfield will fail, sorry,

2550 * (isBankInstruction): modified to return 0 for no banking instruction,
2551 and 1 for banking instruction,
2552 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2553 caused stop processing pCodes after a inline assembly block,
2554 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2556 registers when it shouldn't,
2557 * src/pic16/ralloc.c (allocReg): add preliminary support for
2558 supporting a limited set of temporary registers,
2560 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2562 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2563 genDataPointerSet): ensure assignments always copy in MSB to LSB
2565 (loadRegFromAop): recognize CLRH optimization,
2566 (genFunction): optimize RECEIVE iCodes in reentrant functions
2568 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2570 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2584 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2586 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5520 code / RAM are in the same page / bank. This means the linker can
5521 safely allocate code/RAM of separate ASM files to different pages/banks.
5522 * doc/sdccman.lyx: added Slade's tips

5565 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5567 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5568 loaded with the linker search paths (-L arguments) and the libraries
5569 to be linked with the current source (-l arguments). Changes
5570 currently will affect only the pic16 port.
5571 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5572 include path the port specific paths and port specific libraries,
5573 * gplink command now contains the $3 argument,
5574 * src/pic16/device.h,
5575 * src/pic16/device.c,: structure PIC_device is made public and
5576 renamed to PIC16_device, the same for variable Pics which is renamed

5591 Documenting changes from previous commits.
5592 * configure.in (version 1.56),
5593 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5594 when generating output files to configure the pic16 library,
5595 but now I've commented it out, since gputils aren't installed in the
5596 SF compile farm, so library won't compile
5598 * device/lib/Makefile.in (version 1.56): initially I've added in
5599 target 'all' the prerequestive 'model-pic16' so it compiled the
5600 pic16 library, but now I've commented it out for the same reasons
5602 * added targets 'model-pic16' and 'objects-pic16' to compile the
5604 * added target 'port-specific-objects-pic16' to handle the
5605 generated libraries and copy them into the build/ directory
5606 * added target 'clean-intermediate-pic16' to clean intermediate
5607 files into pic16 directory
5608 * in target 'installdirs' added line to create directory pic16 in
5609 the installation path
5611 * device/include/Makefile.in (version 1.11): in target 'install'
5612 added lines to copy all header files to installation path,
5613 * in target 'installdirs' added line create directory for pic16
5614 headers in the installation path

5629 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5630 option so that it actually works. Made it specific to the z80, since
5631 the gbz80 doesn't have these kinds of I/O ports.
5633 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5635 * device/include/z180.h,

5657 Mainly changes to support compilation of the device libraries
5658 * src/pic16/device.c: stack is allocated via symbol and not
5659 via literal number. The symbol is placed in the corresponding
5660 position of the data ram
5661 * (pic16_dump_section): relocatable and absolute uninitialized
5662 data are now emitted in sorted order to reduce section naming,
5663 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5664 weren't marked as being in the access bank,
5666 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5668 Added portion of GNU PIC Library under the directory
5669 device/include/pic16 and device/lib/pic16. These files
5670 contain the declarations of SFRs for the PIC18Fxx2 devices.
5671 The directory is initialized via configure from toplevel.
5673 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5675 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5700 * doc/sdccman.lyx: Moved and added some sections, small changes
5701 all over. Telling LaTeX to be less strict with word spacing
5702 to better keep the right margin. Changed some notes about
5703 maintainance of the ports in section 3.2.1 - is it OK like this?
5705 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
5707 SDCC source changes:
5708 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

5714 processor registers declared internally by the port are emitted in
5715 the translation as equates,
5716 * src/pic16/gen.c: inline code is passed unprocessed to the

5857 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5859 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5860 (default behaviour).
5862 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5864 A python script to validate compiler diagnostic messages. It can be
5865 used to verify that sdcc complains about bad c source code and
5866 gives a good location of the error.
5867 * support/valdiag/Makefile,
5868 * support/valdiag/valdiag.py,

5886 Bug reported from Jesus Calvino-Fraga
5888 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5890 * sdcc.spec: updated
5891 * device/include/Makefile.in: don't install CVS directories
5892 * device/lib/Makefile.in: added removal of CVS directories after install
5893 * doc/Makefile: fixed install, added local_icons
5894 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5895 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5896 * src/ds390/gen.c (genRightShift): fixed bug #870788
5897 * src/SDCCast.c (decorateType): fixed bug #870781
5899 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5901 PIC16 port related changes:
5902 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5903 added variable stackPos,
5905 * gen.c: genCall, assignResultValue: added support for
5906 pushing/retrieving function parameters to/from stack,
5907 genFunction,genEndFunction: setup stack frame for the
5909 genAddrOf: will be changed according to bug 863624
5911 * added files genutils.c and genutils.h which contain gen*
5912 debugged and optimised functions extracted from gen.c
5914 * glue.c: added variable 'externs' which holds extern symbols,
5915 pic16emitRegularMap: is modified to properly handle relocatable
5916 symbols under the new scheme,
5917 pic16createInterruptVect: is modified
5918 pic16printPublics: is modified to emit 'global' assembler directives,
5919 added pic16_printExterns to print extern symbols,
5920 pic16glue: initializes stack/frame pointer in the beginning of
5921 the assembly output. Temporary hack, will be corrected later,
5922 because gplink yet does not support stack and SDCC does not
5923 yet support a type of crt0.o object to create the final binary.
5925 * Removed many lines that contain 8051 legacy code.
5926 * The code is finally placed under a 'code' directive.
5927 * Added port specific options.
5929 * _process_pragma: simplified since now we do not need *special*
5930 include file to define SFR registers. But a separate header
5931 will be needed. This will be developed later.
5932 * _pic16_parseOptions: added, parses port specific options:
5933 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5934 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5935 --preplace-udata-with=
5937 * _pic16_setDefaultOptions: modified to initialize section names,
5938 but hack is temporarly out of order since it needs improvement.
5939 * _pic16_genAssemblerPreamble: configuration words are emitted by
5940 their address instead of their name. This part is incomplete and
5941 supports only the 18Fxx2 devices. Other devices will emit an error
5942 during assembly since they do not contain the same set of config
5944 * _pic16_genIVT: is modified,
5946 * pcode.c: added definitions for some hardware registers that are needed
5948 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5949 All PCI entries are updated. Now LFSR is supported.
5950 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5951 * added pic16_newpCodeOpLit2 to support instructions with
5952 two literal arguments
5953 * pic16_pCode2str: corrected code that emits assembler instructions
5954 with two literal operands and those that have an access bit modifier
5955 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5956 this fixes a bug which caused some labels to be lost, when an
5957 assembler directive was added, i.e. banksel,
5958 * pic16_FixRegisterBanking: improved logic that causes the insertion
5960 * InlineFunction: functions that are called once, are not any more
5961 inlined. This can be a port option in the future,
5963 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5965 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5966 hold the corresponding uninitialized symbols,
5967 * pic16_allocProcessorRegister: registers have explicit marked the
5969 * pic16_allocInternalRegister: registers are explicit marked as
5971 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5972 processing list, so bit registers were lost,
5975 * ralloc.h: added field 'accessBank' and original symbol operand
5976 in register definition,
5977 * removed the field isMapped from register definition,
5979 ** Several functions have been removed from various sources:
5980 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5981 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5982 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5983 pic16_assignRelocatableRegisters
5985 ** others have been introduced:
5986 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5987 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5989 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5991 * support/scripts/inc2h.pl: changed definition of BIT_AT
5992 to emit 'sbit at' instead of 'bit at'. This was a request.
5994 PIC16 port related preliminary changes:
5995 * gen.c: prefixed function popRegFromString with
5996 pic16_ and all references to it corrected
5997 * pcode.c: all pic16_pc_* hardware registers prefixed
5998 with underscore (_),
5999 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6000 * ralloc.c: newReg(): when register is REG_SFR then
6001 set address to rIdx,
6002 pic16_allocProcessorRegister(): marks register wasUsed=0
6003 pic16_writeUsedRegs(): added a call to assign processor
6004 registers via pic16_assignFixedRegisters
6006 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6008 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6009 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6010 variables in unused register banks. Also the SSEG is placed
6011 wherever there is enough space for it, and IDATA can be anywhere
6012 in internal RAM. For now compile using -Wl-Y[stack_size].
6013 The mem file is different for this option as well, since it
6014 makes no sense of talking about DSEG lenght.
6016 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6018 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6019 in certain cases, e.g. when ROM assignment, patch provided
6020 from Albert den Haan.
6022 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6163 xdata and data memory on startup. Set the environment variable
6164 SDCC_NOGENRAMCLEAR to disable this.
6165 * src/mcs51/peephole.def,
6166 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6167 (allows non-interrupt and interrupt code to safely compete for a resource
6168 without the non-interrupt code having to disable interrupts)
6170 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6178 multiply defined with mismatching "at" address.
6180 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6182 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
6183 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

6909 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6910 to xdata int at 0x1234 tempvar = 1.
6911 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6912 provided by Akiya ISHIDA

6928 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6930 Fixed bug #621531 (const & volatile confusion in the type chain).
6931 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7011 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7012 iCode properly now. Use getSize instead of nRegs since a & b
7013 aren't part of the nRegs tally.
7015 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7017 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7023 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7024 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7025 fetching of the pointer
7026 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7027 copied from genNearPointerSet()
7028 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7029 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7030 If they pop r0/r1 they must be called in the opposite order than aopOp().
7031 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7032 (resp. --stack-auto), prepared for --xstack

7043 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7045 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7046 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7047 type for bits was changed. It resulted in bit variables becoming
7048 global, which is not permitted in PIC 14 assembly output.
7050 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7052 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7065 A few small changes that speed up the peephole optimizer.
7069 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7071 Try to make the peephole optimizer smarter by maintaining
7072 an association between the assembly source code and the
7073 iCodes that originated them. Put this information to use
7074 with a new peephole rule condition "notVolatile" so that
7075 the rules can be aggressive yet still safe.
7080 * src/mcs51/peeph.def
7082 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7086 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7087 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7088 if the left or right operand symbols have the accuse flag set.
7090 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7092 Changed the type of the result of the ! (NOT) operator to char;
7093 previously it returned the same type as the source. This allows
7094 us to eliminate all the genFloatNot functions (all of its target
7095 implementations were very buggy) since !float can use the same
7098 * src/SDCCicode.c (ast2iCode): ! returns char

7105 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7107 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7108 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7109 during interrupts. Ensure WSAVE is located at a shared bank address.
7110 2. Fixed page selection in some places
7111 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7112 the registers name strings.
7113 4. Fixed "signed / unsigned compare" compiler warnings.
7114 5. The PIC port manages its own allocation of the general purpose
7115 registers, but makes no attempt to reuse them. As a result when
7116 compiling it soon runs out of general purpose registers. Some
7117 additional code was added to the files pcode.c and device.c to walk
7118 through the function call tree and rename the registers so that they
7128 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7129 genPlus() & genMinus() when the result is the same as left or right
7131 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7135 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7137 Made bitfield a distinct type from bit so that bitfields
7138 convert as per ANSI C and bits retain their traditional
7139 boolean style behaviour. Implemented bitfield support in
7147 * src/ds390/gen.c: bit v bitfield split
7148 * src/z80/gen.c: New support for bitfields
7149 * support/regression/tests/bitfields.c: reenabled z80,
7152 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7154 Rules 246.x, 247.x relate to bitfields, the others speed up
7155 access to xdata mapped I/O devices.
7157 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7159 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7161 Cleaned up genPackBits and genUnpackBits and added two helper
7162 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7163 for literal assignments in genPackBits (thanks to Frieder for
7169 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7171 Fixed bug #748310 (pointer to function type mishandled when the
7172 function name is omitted). Also fixed a SIGSEGV when a function
7173 attribute (reentrant, etc) is used on a non-function or on a
7174 function but misplaced before the parameter list.
7176 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7178 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7179 * support/Util/SDCCerr.h,
7180 * support/Util/SDCCerr.c: Added func attr misuse error msg
7182 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7184 Fixed bug #787649 by anonymous
7185 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

7201 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7203 Made the constant following the "interrupt" keyword optional. If
7204 omitted, the function will not automatically be given an entry
7205 in the interrupt vector table (similar to #pragma NOIV, but
7206 less syntacticly kludgy). The interrupt number is also now
7207 range checked. Also fixed a bug in the high order bit example

7734 added --disable-pic16-port
7735 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7736 * src/SDCCmain.c: linkOptions is changed to set *,
7737 added if/endif conditional macros to remove options help
7738 messages from optionsTable when a port is not configured, added
7739 support for the PIc16 port in the ports table, when executing
7740 the compiler with no port specified on command line, a default
7741 port is selected with the new macro DEFAULT_PORT which is
7742 defined in port.h, in setDefaultOptions() linkOptions is removed
7743 from initialization assignment, since now it is a set,
7744 parseCmdLine uses setParseWithComma for linkOptions, in
7745 linkEdit() linkOptions are accessed with new function indexSet()
7746 which returns the i'th item of a set variable. See SDCCset.c, in
7747 linkEdit() when calling buildCmdLine(), added linkOptions as
7748 last argument. Now users can pass arguments to gplink via the
7749 -Wl option, main() uses pic16glue() to glue up pic16 programs

7761 * src/pic16/glue.c: commented out some error producing lines
7762 * src/pic16/main.c: __config directives are commented out to stop
7763 gpasm complaining and test the linkage with gplink, _linkCmd and
7764 _asmCmd changed to be more gplink and gpasm friendly
7765 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7766 produced an error when parsed, peep rule 12 is added to utilize
7767 movff, but it is commented out since the pCode does not support
7768 yet a command with 2 address arguments

8807 * src/SDCCicode.c: fixed array add
8809 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8810 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8811 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8813 2003-01-04 <johan AT balder>
8815 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8817 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8818 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8820 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8821 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8827 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8828 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8830 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8831 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8833 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8835 * in \sdcc\as\mcs51\ changed these files in order to create an
8836 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8837 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8838 following files to include the previous two files: aslink.dsp,
8839 Makefile.aslink, Makefile.bcc, and Makefile.in.
8841 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8842 .adb instead of .cdb
8844 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8846 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8847 value from option --iram-size.
8849 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8851 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8854 2002-09-18 <wiml AT hhhh.org>
8856 * SDCClrange.h: exposed setFromRange() and setToRange()
8857 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8858 packRegsForAccUse() (bug 542397)
8859 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8860 multiple times and emitting the fetch operations more than once
8861 added aopGetUsesAcc() function to allow binary operators to
8862 fetch their operands in the correct order; made genMinus() emit
8863 compact code for X = LITERAL - Y
8865 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8866 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8867 sprintf() in line 1267.
8869 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8870 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8873 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8874 Changes to aslink (All the changes are marked with 'JCF'):
8876 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8879 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8880 area BSEG. Also moves, if possible, the DATA area down into the internal
8881 ram so more space is available.
8883 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8886 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8887 not bytes. Function summary() which creates a memory usage summary
8888 file with extension .mem. Reports of overlaping stack and small stack
8889 size. If the space for the stack is less than 16 bytes aslink trows a
8892 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8893 the 8051. Option 'y' for memory summary output file.
8895 Changes to sdcc (All the changes are marked with 'JCF'):
8897 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8899 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8900 overlaying area for it (uses RegBankUsed[4]).
8902 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8903 bank zero as used by default. By default aslink locates the stack
8904 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8905 the creation of the .mem file. Delegates the allocation of data area
8906 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8907 the begining of the stack area to aslink.
8909 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8910 glue() in SDCCglue.c creates an area for it.
8912 2002-09-03 Borut Razem <borut.razem AT siol.net>
8913 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8914 sdcc/src/pic/glue.c:
8915 introduced atexit() handler for teporay files removal in case of
8916 errors, assertions, ...
8918 2002-08-29 Borut Razem <borut.razem AT siol.net>
8919 * sdcc/support/cpp2/auto-host_vc_in.h:
8920 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8921 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8922 Maybe there is a similar problem with BORLANDC? It should be checked!
8924 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8925 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8926 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8927 was not executed, and the compiler (cl) launched a warning:
8928 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8930 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8931 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8933 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8934 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8936 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8937 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8938 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8939 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8940 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8941 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8942 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8943 - added Release configuration in VS projects
8944 - review of compiler an linker options
8945 - VC .exe files are generated in bin_vc directory, not to interfere
8946 with binaries generated from other projects (cygwin, mingw, bcc ...)
8948 * sdcc/src/yacc.dsp: added
8950 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8951 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8952 and insert the version number definitions from .version
8954 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8956 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8957 added - genarate auto-host.h using auto-host_vc_in.h as template
8960 removed from CVS, generated automatically
8962 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8963 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8965 2002-08-11 Borut Razem <borut.razem AT siol.net>
8966 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8968 2002-08-10 Borut Razem <borut.razem AT siol.net>
8969 * src/SDCCmain.c (main):
8970 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8971 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8972 The consequence was that some temporary files were not removed.
8975 unification of code in functions tempfilename() and tempfile():
8976 function tempnam() is defined in Visual Studio 6.0 and .NET
8978 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8980 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8981 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8982 - removed compiler command line option /WX: Treats all warnings as errors
8983 - update a list of source files, included into the project
8985 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8986 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8987 changed project type to Generic Project so that can be correcly converted to VS.NET project
8989 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8991 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8993 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8995 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8996 added return 0 statements after assert() to make compiler happy
8998 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8999 added newline in the def file to keep MSC compiler satisfied
9001 * sdcc/src/z80/gen.c:
9002 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9003 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9004 - solved MSC error in function aopDump()
9006 * sdcc_vc.h: define PREFIX as "\\sdcc"
9008 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9009 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9011 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9012 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9013 - Rewrote the register banking algorithm.
9014 - Added pCode live-range analysis to registers (for now, only non-used and
9015 singly-used registers optimized away)
9017 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9019 * 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.
9021 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9022 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

9044 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9046 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9048 2002-03-28 Johan Knol <johan AT balder>
9050 * src/SDCCval.c: fixed bug #532436
9052 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9054 Added "char *Processor" field to the port structure.
9057 Added -p option. Allows port dependent processor to be specified.
9060 Initialized the new field char *Processor field to NULL in all ports
9063 Compiler generated registers for interrupt context saving
9064 were not getting allocated.
9066 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9069 Fixed left shift. Will promote the left side of a left shift
9070 if a) left shifting more than size of operand or b) when assigned
9071 to something size > size of left side
9073 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9075 tons of changes. Register allocation has been
9076 rewritten. Added customization for the various PICs. Flow
9077 analysis is restructured. ...
9083 Added. device.c is a PIC port hack to accomodate variations
9086 2002-03-13 Michael Hope <michaelh AT vroom>
9088 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9090 2002-03-04 johanknol <johanknol AT manik>
9092 * /src/SDCCval.c: fixed
9094 const unsigned char arr[][2] = { { 0, 1 } };
9095 t18.c:1: error: Initializer element is not constant
9097 2002-03-04 bela <bela AT manik>
9099 * /device/include/mcs51reg.h:
9100 ds89c420 register definition update
9102 2002-03-03 <johan AT FRIJA>
9104 * support/Util/SDCCerr.c: did something, but don't no why anymore
9106 * support/regression/tests/bug-524691.c: made it a little less shy
