1759 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1761 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

1765 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1766 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1767 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1768 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1769 always available in leading double underscore form. The C99 support is
1770 mostly missing, but it's a start.
1771 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1772 reserved identifier "__data".
1774 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1850 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1852 * device/lib/printf_large.c: removed inline assembly for portability and
1853 readability. Use printf_fast if speed or size are more important.
1854 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1855 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1857 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1859 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1860 prevent compiler warning
1862 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1864 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1865 moved to level 0 and declared as static. Also they are explicit
1866 placed in access bank. This was necessery because some times they
1867 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1868 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1869 optimizations. Currently only compare to unsigned char is implemented,
1870 * src/pic16/gen.c: added fReturnIdx array,
1871 * (struct resolvedIfx) is moved to gen.h and made public,
1872 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1873 * (aopForSym): added an optimization to directly store in stack of
1874 the operand of a SEND iCode,
1875 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1876 but as registers instead (AOP_REG) using the fReturnIdx array,
1877 * (pic16_freeAsmop): remove the freed register from the
1878 _G.sregsAlloc field,
1879 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1880 a compare of 'WREG',
1881 * (pic16_popGetTempRegCond): changed function prototype, now
1882 function takes also a bitVector argument v which holds the current
1883 set of registers that are allocated for stack access by aopForSym,
1884 registers allocated in aopForSym for accessing stack symbols are not
1885 any more part of the functions usedRegs field,
1886 * (genCall): some times aopOp is called for a stack variable to be
1887 send, aopForSym might perform the push, if this is true make sure
1888 that genCall doesn't push the variable twice by testing _G.resDirect,
1889 * (genFunction): changed testing for unspecified interrupt number
1890 from 256 to INTNO_UNSPEC,
1891 * modified selection scheme of frame pointer generation. Previously
1892 if function did use local registers a frame pointer was generated,
1893 now a frame pointer is generated only if function has arguments
1894 (that need PLUSW2 register access), or has stack arguments, or the
1895 compiler is not instructed to omit the frame pointer,
1896 * (genEndFunction): before restoring local registers that were saved
1897 in the function preamble, also restore the registers that *might*
1898 have been allocated for stack access,
1899 * (genRet): removed some old comments,
1900 * (genCmp, the active (RN's) version): added a call to the
1901 pic16_genCmp_special function to perform the compare with a more
1902 robust and optimized way,
1903 * (genInline): a feature has been added in inline code generation,
1904 which allows a wildcard variable substitution when writing inline
1905 assembly. Code is incomplete and experimental therefore undocumented,
1906 * (genCast): changed order of aopOp for result and right to allow
1907 aopForSym to directly load the result if possible,
1908 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1909 perform an optimized compare on some selected special occasions,
1910 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1911 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1912 generate an IVT any more,
1913 * src/pic16/main.c (pic16_optionsTable): added command line option
1915 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1916 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1918 * src/pic16/NOTES: Raphael Neider added in list of active developers
1919 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1920 jumptable_end to prevent bug #,
1921 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1922 inCond and outCond fields,
1923 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1924 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1925 turn off register spilling,
1926 * (packRegsForOneUse): synced with other ports' versions although it
1927 is not used currently,
1928 * (pic16_packRegisters): added an optimization while reading
1929 structure bitfields, some registers may be saved (malloc code is
1930 decreased by 80 bytes)
1932 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1934 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1935 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1936 this can be optimized more?
1938 2005-03-10 Raphael Neider <rneider AT web.de>
1940 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1941 genNearPointerGet): (hopefully) fixed access to bitfields via
1942 pointers (p->bitN = x; and x = p->bitN; failed)
1944 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2121 * src/pic16/main.c (_process_pragma): fixed another malloc bug
2122 (sizeof(sectNames) changed to sizeof(sectName))

2130 of (byte sized) temporaries (assign them to WREG for now)
2131 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2132 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2133 this might fix SIGSEGVs on MinGW...
2134 * src/SDCCopt.c (killDeadCode): restored original behaviour
2135 (volatile operands might get thrown away though)
2137 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
2139 * src/pic16/gen.c: fixed bug #1106975,

2600 * src/pic16/device.h,
2601 * src/pic16/genarith.c,
2604 * src/pic16/pcode.c: applied patches #1068154 and #1070213
2606 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
2608 Large cummulative patch for pic16 port.
2609 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
2610 to call when a stack overflow occurs,
2611 * (malloc.h): added CVS Id tag,
2612 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2614 * added libc directory. The current version of LibC contains string
2615 functions, ctype functions and macros and some functions of the
2616 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2617 be extensively tested in the future. Standard disclaimer here.
2618 Library is not automatically build yet. But one can build it by
2619 invoking 'make' inside the libc directory.
2620 * added ADC library under libio. Preliminary version yet.
2622 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
2623 * src/pic16/gen.c (aopForRemat): asmop size is filled by
2624 aopForRemat() now and not by pic16_aopOp(),
2625 * (pic16_popGetTempReg): removed warning messgae when allocating
2626 temporary registers, its a buggy feature and will be removed,
2627 * (pic16_popGet): set register instance field in AOP_CRY,
2628 * (pic16_outBitC): fixed for results in size greater than 1,
2629 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2630 * (pic16_storeForReturn): optimized return of 0,
2631 * (genCmp): experimental code for new genCmp which uses PIC18's
2632 special compare&skip instructions. Initial tests fail some times
2633 with variables grater than 1 byte in size, so new code is disabled,
2634 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2636 * (genCast): began a fix to optimize the casting of a bit to another
2637 bit, now assigning a bitfield to another bitfield will fail, sorry,
2638 * src/pic16/main.c: disabled the use of lr-support feature,
2639 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
2640 * added some function prototypes, added function _debugf prototype,
2641 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
2642 bits with offset (case PO_GPR_BIT),
2643 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2645 * (isBankInstruction): modified to return 0 for no banking instruction,
2646 and 1 for banking instruction,
2647 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2648 caused stop processing pCodes after a inline assembly block,
2649 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2650 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2651 registers when it shouldn't,
2652 * src/pic16/ralloc.c (allocReg): add preliminary support for
2653 supporting a limited set of temporary registers,
2655 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2657 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2658 genDataPointerSet): ensure assignments always copy in MSB to LSB
2660 (loadRegFromAop): recognize CLRH optimization,
2661 (genFunction): optimize RECEIVE iCodes in reentrant functions
2663 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2665 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
2666 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
2668 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

2674 * device/lib/_gptrget.c (_gptrget),
2675 * device/lib/_gptrgetc.c (_gptrgetc),
2676 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
2677 instead of sjmp to ret
2678 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
2679 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

5663 loaded with the linker search paths (-L arguments) and the libraries
5664 to be linked with the current source (-l arguments). Changes
5665 currently will affect only the pic16 port.
5666 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5667 include path the port specific paths and port specific libraries,

5688 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5689 when generating output files to configure the pic16 library,
5690 but now I've commented it out, since gputils aren't installed in the
5691 SF compile farm, so library won't compile
5693 * device/lib/Makefile.in (version 1.56): initially I've added in
5694 target 'all' the prerequestive 'model-pic16' so it compiled the
5695 pic16 library, but now I've commented it out for the same reasons
5697 * added targets 'model-pic16' and 'objects-pic16' to compile the
5699 * added target 'port-specific-objects-pic16' to handle the
5700 generated libraries and copy them into the build/ directory
5701 * added target 'clean-intermediate-pic16' to clean intermediate
5702 files into pic16 directory
5703 * in target 'installdirs' added line to create directory pic16 in
5704 the installation path
5706 * device/include/Makefile.in (version 1.11): in target 'install'
5707 added lines to copy all header files to installation path,
5708 * in target 'installdirs' added line create directory for pic16
5709 headers in the installation path

5724 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5725 option so that it actually works. Made it specific to the z80, since
5726 the gbz80 doesn't have these kinds of I/O ports.
5728 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5730 * device/include/z180.h,

5736 * device/lib/_strcmp.c,
5737 * device/lib/_strtok.c: fixed pragmas to non-deprecated form
5738 * src/z80/main.c (_process_pragma): add support for pragmas bank and
5739 portmode; added deprecation warning for bank= and protmode= forms.
5740 Also, guard against buffer overflow.
5741 * src/z80/gen.c (aopGet): generate better code for sfr banked read
5743 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5745 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also

5752 Mainly changes to support compilation of the device libraries
5753 * src/pic16/device.c: stack is allocated via symbol and not
5754 via literal number. The symbol is placed in the corresponding
5755 position of the data ram
5756 * (pic16_dump_section): relocatable and absolute uninitialized
5757 data are now emitted in sorted order to reduce section naming,
5758 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5759 weren't marked as being in the access bank,
5761 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5763 Added portion of GNU PIC Library under the directory
5764 device/include/pic16 and device/lib/pic16. These files
5765 contain the declarations of SFRs for the PIC18Fxx2 devices.
5766 The directory is initialized via configure from toplevel.
5768 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5770 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
5771 the spilllocations to be compared correctly

5795 * doc/sdccman.lyx: Moved and added some sections, small changes
5796 all over. Telling LaTeX to be less strict with word spacing
5797 to better keep the right margin. Changed some notes about
5798 maintainance of the ports in section 3.2.1 - is it OK like this?
5800 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5837 UPPER for immediate operands,
5838 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5840 * src/pic16/peeph.def: all peepholes with movff are commented out,
5841 because there is a problem in the pcode peep optimizer,
5842 * src/pic16/ralloc.c: the register allocator can now reuse local
5843 function symbols for another function. This saves register usage.
5844 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5846 Added file src/pic16/NOTES with information about program writing on
5847 the current port version.

5900 needLinkerScript flag
5902 * src/pic16/gen.c (genAddrOf): fixed bug #863624
5903 * src/pic/glue.c: added variable udata_section_name to
5904 override default uninitialized data segment definition for

5935 include information about variables allocated to the overlay
5938 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5940 * as/mcs51/lkmain.c: Help about -Y option

5952 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5954 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5955 (default behaviour).
5957 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5959 A python script to validate compiler diagnostic messages. It can be
5960 used to verify that sdcc complains about bad c source code and
5961 gives a good location of the error.
5962 * support/valdiag/Makefile,
5963 * support/valdiag/valdiag.py,
5964 * support/valdiag/tests/*
5966 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5979 * src/common.h: added ifndef/define/endif macros
5980 around the header file.
5981 Bug reported from Jesus Calvino-Fraga
5983 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5985 * sdcc.spec: updated
5986 * device/include/Makefile.in: don't install CVS directories
5987 * device/lib/Makefile.in: added removal of CVS directories after install
5988 * doc/Makefile: fixed install, added local_icons
5989 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5990 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5991 * src/ds390/gen.c (genRightShift): fixed bug #870788
5992 * src/SDCCast.c (decorateType): fixed bug #870781
5994 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5996 PIC16 port related changes:
5997 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5998 added variable stackPos,
6000 * gen.c: genCall, assignResultValue: added support for
6001 pushing/retrieving function parameters to/from stack,
6002 genFunction,genEndFunction: setup stack frame for the
6004 genAddrOf: will be changed according to bug 863624
6006 * added files genutils.c and genutils.h which contain gen*
6007 debugged and optimised functions extracted from gen.c
6009 * glue.c: added variable 'externs' which holds extern symbols,
6010 pic16emitRegularMap: is modified to properly handle relocatable
6011 symbols under the new scheme,
6012 pic16createInterruptVect: is modified
6013 pic16printPublics: is modified to emit 'global' assembler directives,
6014 added pic16_printExterns to print extern symbols,
6015 pic16glue: initializes stack/frame pointer in the beginning of
6016 the assembly output. Temporary hack, will be corrected later,
6017 because gplink yet does not support stack and SDCC does not
6018 yet support a type of crt0.o object to create the final binary.
6020 * Removed many lines that contain 8051 legacy code.
6021 * The code is finally placed under a 'code' directive.
6022 * Added port specific options.
6024 * _process_pragma: simplified since now we do not need *special*
6025 include file to define SFR registers. But a separate header
6026 will be needed. This will be developed later.
6027 * _pic16_parseOptions: added, parses port specific options:
6028 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6029 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6030 --preplace-udata-with=
6032 * _pic16_setDefaultOptions: modified to initialize section names,
6033 but hack is temporarly out of order since it needs improvement.
6034 * _pic16_genAssemblerPreamble: configuration words are emitted by
6035 their address instead of their name. This part is incomplete and
6036 supports only the 18Fxx2 devices. Other devices will emit an error
6037 during assembly since they do not contain the same set of config
6039 * _pic16_genIVT: is modified,
6041 * pcode.c: added definitions for some hardware registers that are needed
6043 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6044 All PCI entries are updated. Now LFSR is supported.
6045 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6046 * added pic16_newpCodeOpLit2 to support instructions with
6047 two literal arguments
6048 * pic16_pCode2str: corrected code that emits assembler instructions
6049 with two literal operands and those that have an access bit modifier
6050 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6051 this fixes a bug which caused some labels to be lost, when an
6052 assembler directive was added, i.e. banksel,
6053 * pic16_FixRegisterBanking: improved logic that causes the insertion
6055 * InlineFunction: functions that are called once, are not any more
6056 inlined. This can be a port option in the future,
6058 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6060 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6061 hold the corresponding uninitialized symbols,
6062 * pic16_allocProcessorRegister: registers have explicit marked the
6064 * pic16_allocInternalRegister: registers are explicit marked as
6066 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6067 processing list, so bit registers were lost,
6070 * ralloc.h: added field 'accessBank' and original symbol operand
6071 in register definition,
6072 * removed the field isMapped from register definition,
6074 ** Several functions have been removed from various sources:
6075 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6076 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6077 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6078 pic16_assignRelocatableRegisters
6080 ** others have been introduced:
6081 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6082 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6084 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6086 * support/scripts/inc2h.pl: changed definition of BIT_AT
6087 to emit 'sbit at' instead of 'bit at'. This was a request.
6089 PIC16 port related preliminary changes:
6090 * gen.c: prefixed function popRegFromString with
6091 pic16_ and all references to it corrected
6092 * pcode.c: all pic16_pc_* hardware registers prefixed
6093 with underscore (_),
6094 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6095 * ralloc.c: newReg(): when register is REG_SFR then
6096 set address to rIdx,
6097 pic16_allocProcessorRegister(): marks register wasUsed=0
6098 pic16_writeUsedRegs(): added a call to assign processor
6099 registers via pic16_assignFixedRegisters
6101 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6103 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6104 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6105 variables in unused register banks. Also the SSEG is placed
6106 wherever there is enough space for it, and IDATA can be anywhere
6107 in internal RAM. For now compile using -Wl-Y[stack_size].
6108 The mem file is different for this option as well, since it
6109 makes no sense of talking about DSEG lenght.
6111 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6113 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6114 in certain cases, e.g. when ROM assignment, patch provided
6115 from Albert den Haan.
6117 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6670 not occur if the control variable is involved with a
6671 relational operator.

7183 if the left or right operand symbols have the accuse flag set.
7185 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7187 Changed the type of the result of the ! (NOT) operator to char;
7188 previously it returned the same type as the source. This allows
7189 us to eliminate all the genFloatNot functions (all of its target
7190 implementations were very buggy) since !float can use the same
7193 * src/SDCCicode.c (ast2iCode): ! returns char
7194 * src/mcs51/gen.c (genNot, genNotFloat),
7195 * src/ds390/gen.c (genNot, genNotFloat),

7202 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7203 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7204 during interrupts. Ensure WSAVE is located at a shared bank address.
7205 2. Fixed page selection in some places
7206 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7207 the registers name strings.
7208 4. Fixed "signed / unsigned compare" compiler warnings.
7209 5. The PIC port manages its own allocation of the general purpose
7210 registers, but makes no attempt to reuse them. As a result when
7211 compiling it soon runs out of general purpose registers. Some
7212 additional code was added to the files pcode.c and device.c to walk
7213 through the function call tree and rename the registers so that they
7223 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7224 genPlus() & genMinus() when the result is the same as left or right

7230 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7232 Made bitfield a distinct type from bit so that bitfields
7233 convert as per ANSI C and bits retain their traditional
7234 boolean style behaviour. Implemented bitfield support in
7242 * src/ds390/gen.c: bit v bitfield split
7243 * src/z80/gen.c: New support for bitfields
7244 * support/regression/tests/bitfields.c: reenabled z80,
7247 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7249 Rules 246.x, 247.x relate to bitfields, the others speed up
7250 access to xdata mapped I/O devices.
7252 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7254 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7256 Cleaned up genPackBits and genUnpackBits and added two helper
7257 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7258 for literal assignments in genPackBits (thanks to Frieder for
7264 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7266 Fixed bug #748310 (pointer to function type mishandled when the
7267 function name is omitted). Also fixed a SIGSEGV when a function
7268 attribute (reentrant, etc) is used on a non-function or on a
7269 function but misplaced before the parameter list.

7296 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7298 Made the constant following the "interrupt" keyword optional. If
7299 omitted, the function will not automatically be given an entry
7300 in the interrupt vector table (similar to #pragma NOIV, but
7301 less syntacticly kludgy). The interrupt number is also now
7302 range checked. Also fixed a bug in the high order bit example

7778 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7779 the regression tests I'm not brave enough to enable 245.b, 245.c
7780 * doc/sdccman.lyx: added latex preamble for hyperref package.
7781 Using pdflatex this will give you a hyperlinked pdf file with
7782 bookmarks. (prepend '%' before /usepackage if this breaks something)

7829 added --disable-pic16-port
7830 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7831 * src/SDCCmain.c: linkOptions is changed to set *,
7832 added if/endif conditional macros to remove options help
7833 messages from optionsTable when a port is not configured, added
7834 support for the PIc16 port in the ports table, when executing
7835 the compiler with no port specified on command line, a default
7836 port is selected with the new macro DEFAULT_PORT which is
7837 defined in port.h, in setDefaultOptions() linkOptions is removed
7838 from initialization assignment, since now it is a set,
7839 parseCmdLine uses setParseWithComma for linkOptions, in
7840 linkEdit() linkOptions are accessed with new function indexSet()
7841 which returns the i'th item of a set variable. See SDCCset.c, in
7842 linkEdit() when calling buildCmdLine(), added linkOptions as
7843 last argument. Now users can pass arguments to gplink via the
7844 -Wl option, main() uses pic16glue() to glue up pic16 programs

7856 * src/pic16/glue.c: commented out some error producing lines
7857 * src/pic16/main.c: __config directives are commented out to stop
7858 gpasm complaining and test the linkage with gplink, _linkCmd and
7859 _asmCmd changed to be more gplink and gpasm friendly
7860 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7861 produced an error when parsed, peep rule 12 is added to utilize
7862 movff, but it is commented out since the pCode does not support
7863 yet a command with 2 address arguments
7865 2003-05-18 <johan AT balder>
7867 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7892 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7894 2003-05-11 Borut Razem <borut.razem AT siol.net>
7896 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7897 the path of bin directory, so that PATH is the only env. variable, which has to be set
7898 in case of standard installation.

8908 2003-01-04 <johan AT balder>
8910 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8912 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8928 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8930 * in \sdcc\as\mcs51\ changed these files in order to create an
8931 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8932 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8933 following files to include the previous two files: aslink.dsp,
8934 Makefile.aslink, Makefile.bcc, and Makefile.in.
8936 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8937 .adb instead of .cdb
8939 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8941 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8942 value from option --iram-size.
8944 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8946 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8949 2002-09-18 <wiml AT hhhh.org>
8951 * SDCClrange.h: exposed setFromRange() and setToRange()
8952 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8953 packRegsForAccUse() (bug 542397)
8954 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8955 multiple times and emitting the fetch operations more than once
8956 added aopGetUsesAcc() function to allow binary operators to
8957 fetch their operands in the correct order; made genMinus() emit
8958 compact code for X = LITERAL - Y
8960 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8961 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8962 sprintf() in line 1267.
8964 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8965 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8968 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8969 Changes to aslink (All the changes are marked with 'JCF'):
8971 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8974 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8975 area BSEG. Also moves, if possible, the DATA area down into the internal
8976 ram so more space is available.
8978 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8981 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8982 not bytes. Function summary() which creates a memory usage summary
8983 file with extension .mem. Reports of overlaping stack and small stack
8984 size. If the space for the stack is less than 16 bytes aslink trows a
8987 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8988 the 8051. Option 'y' for memory summary output file.
8990 Changes to sdcc (All the changes are marked with 'JCF'):
8992 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8994 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8995 overlaying area for it (uses RegBankUsed[4]).
8997 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8998 bank zero as used by default. By default aslink locates the stack
8999 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9000 the creation of the .mem file. Delegates the allocation of data area
9001 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9002 the begining of the stack area to aslink.
9004 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9005 glue() in SDCCglue.c creates an area for it.
9007 2002-09-03 Borut Razem <borut.razem AT siol.net>
9008 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9009 sdcc/src/pic/glue.c:
9010 introduced atexit() handler for teporay files removal in case of
9011 errors, assertions, ...
9013 2002-08-29 Borut Razem <borut.razem AT siol.net>
9014 * sdcc/support/cpp2/auto-host_vc_in.h:
9015 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9016 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9017 Maybe there is a similar problem with BORLANDC? It should be checked!
9019 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9020 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9021 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9022 was not executed, and the compiler (cl) launched a warning:
9023 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9025 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9026 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9028 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

9037 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9038 - added Release configuration in VS projects
9039 - review of compiler an linker options
9040 - VC .exe files are generated in bin_vc directory, not to interfere
9041 with binaries generated from other projects (cygwin, mingw, bcc ...)
9043 * sdcc/src/yacc.dsp: added
9045 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9046 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9047 and insert the version number definitions from .version
9049 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9051 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9052 added - genarate auto-host.h using auto-host_vc_in.h as template
9055 removed from CVS, generated automatically
9057 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9058 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9060 2002-08-11 Borut Razem <borut.razem AT siol.net>
9061 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9063 2002-08-10 Borut Razem <borut.razem AT siol.net>
9064 * src/SDCCmain.c (main):
9065 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9066 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9067 The consequence was that some temporary files were not removed.
9070 unification of code in functions tempfilename() and tempfile():
9071 function tempnam() is defined in Visual Studio 6.0 and .NET
9073 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9075 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9076 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9077 - removed compiler command line option /WX: Treats all warnings as errors
9078 - update a list of source files, included into the project
9080 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

9278 * sdcc/src/SDCCloop.c:
9279 Previous fix was not good. basic blocks that have "break" or "return" are
9280 not really partof a loop , but live ranges used in these blocks should
9281 be live thru the entire loop, so set partOfLoop but don't add them to
