2008-09-26If we have a function with an unreachable statement such that the ending debugBill Wendling
information is in an unreachable block, then it's possible that the high/low pc values won't be set for the dwarf information. E.g., this function: void abort(void) __attribute__((__noreturn__)); void dead_beef(void) __attribute__ ((noreturn)); int *b; void dead_beef(void) { *b=0xdeadbeef; abort(); } has a call to "@llvm.dbg.region.end" only in the unreachable block: define void @dead_beef() noreturn nounwind { entry: call void @llvm.dbg.func.start(...) call void @llvm.dbg.stoppoint(...) ... call void @abort( ) noreturn nounwind unreachable return: ; No predecessors! call void @llvm.dbg.stoppoint(...) call void @llvm.dbg.region.end(...) ret void } The dwarf information emitted is something like: 0x00000084: TAG_subprogram [5] AT_name( "dead_beef" ) AT_external( 0x01 ) AT_prototyped( 0x01 ) AT_decl_file( 0x01 ) AT_decl_line( 0x08 ) Note that this is *not* the best fix for this problem, but a band-aid for an gaping wound. This code needs to be changed when we revamp our debugging information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56628 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-24Next round of earlyclobber handling. Approach theDale Johannesen
RA problem by expanding the live interval of an earlyclobber def back one slot. Remove overlap-earlyclobber throughout. Remove earlyclobber bits and their handling from live internals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56539 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-17Add a bit to mark operands of asm's that conflictDale Johannesen
with an earlyclobber operand elsewhere. Propagate this bit and the earlyclobber bit through SDISel. Change linear-scan RA not to allocate regs in a way that conflicts with an earlyclobber. See also comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56290 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Move the uglier parts of deciding not to emit aDale Johannesen
UsedDirective for some symbols in llvm.used into Darwin-specific code. I've decided LessPrivateGlobal is potentially a useful abstraction and left it in the target-independent area, with improved comment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56024 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-09Fix logic for not emitting no-dead-strip for someDale Johannesen
objects in llvm.used (thanks Anton). Makes visible the magic 'l' prefix for symbols on Darwin which are to be passed through the assembler, then removed at linktime (previously all references to this had been hidden in the ObjC FE code, oh well). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55973 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-03Do not emit a UsedDirective for things in the llvm.usedDale Johannesen
list that have internal linkage; the linker doesn't need or want this. (These objects must still be preserved at compile time, so just removing them from the llvm.used list doesn't work.) Should affect only Darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55722 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-17Rename some GC classes so that their roll will hopefully be clearer.Gordon Henriksen
In particular, Collector was confusing to implementors. Several thought that this compile-time class was the place to implement their runtime GC heap. Of course, it doesn't even exist at runtime. Specifically, the renames are: Collector -> GCStrategy CollectorMetadata -> GCFunctionInfo CollectorModuleMetadata -> GCModuleInfo CollectorRegistry -> GCRegistry Function::getCollector -> getGC (setGC, hasGC, clearGC) Several accessors and nested types have also been renamed to be consistent. These changes should be obvious. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54899 91177308-0d34-0410-b5e6-96231b3b80d8
