2008-10-02"The original bug was a complaint that _mm_srli_si128 mis-compiled when passedBill Wendling
a constant vector ("{0x123, 0x456}" syntax). The fix is to simplify the _mm_srli_si128 macro, and move the "* 8" from the macro into the compiler back-end. I can't change the existing __builtins because so many people are using them :-(."

2008-10-01Factorize code: remove variants of "strip offDuncan Sands
pointer bitcasts and GEP's", and centralize the logic in Value::getUnderlyingObject. The difference with stripPointerCasts is that stripPointerCasts only strips GEPs if all indices are zero, while getUnderlyingObject strips GEPs no matter what the indices are. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56922 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-01Implement the -fno-builtin option in the front-end, not in the back-end.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56900 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-30Add the new `-no-builtin' flag. This flag is meant to mimic the GCCBill Wendling
`-fno-builtin' flag. Currently, it's used to replace "memset" with "_bzero" instead of "__bzero" on Darwin10+. This arguably violates the meaning of this flag, but is currently sufficient. The meaning of this flag should become more specific over time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56885 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-30Optimize SelectionDAG's AssignTopologicalOrder even further.Dan Gohman
Completely eliminate the TopOrder std::vector. Instead, sort the AllNodes list in place. This also eliminates the need to call AllNodes.size(), a linear-time operation, before performing the sort. Also, eliminate the Sources temporary std::vector, since it essentially duplicates the sorted result as it is being built. This also changes the direction of the topological sort from bottom-up to top-down. The AllNodes list starts out in roughly top-down order, so this reduces the amount of reordering needed. Top-down is also more convenient for Legalize, and ISel needed only minor adjustments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56867 91177308-0d34-0410-b5e6-96231b3b80d8

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
