2011-02-01[AVX] Implement EnforceSmallerThan for mixed int/fp type lists. ThisDavid Greene
makes type checking for extract_subvector and insert_subvector more robust and will allow stricter typechecking of more patterns in the future. This change handles int and fp as disjoint sets so that it will enforce integer types to be smaller than the largest integer type and fp types to be smaller than the largest fp type. There is no attempt to check type sizes across the int/fp sets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124672 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-30Respect the -tail-dup-size command line option even when optimizing for size.Jakob Stoklund Olesen
This is similar to the -unroll-threshold option. There should be no change in behavior when -tail-dup-size is not explicit on the llc command line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124564 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-30Transform (X/Y)*Y into X if the division is exact. Instcombine already ↵Duncan Sands
knows how to do this and more, but would only do it if X/Y had only one use. Spotted as the most common missed simplification in SPEC by my auto-simplifier, now that it knows about nuw/nsw/exact flags. This removes a bunch of multiplications from 447.dealII and 483.xalancbmk. It also removes a lot from tramp3d-v4, which results in much more inlining. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124560 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-30Teach DAGCombine to fold fold (sra (trunc (sr x, c1)), c2) -> (trunc (sra x, ↵Benjamin Kramer
c1+c2) when c1 equals the amount of bits that are truncated off. This happens all the time when a smul is promoted to a larger type. On x86-64 we now compile "int test(int x) { return x/10; }" into movslq %edi, %rax imulq $1717986919, %rax, %rax movq %rax, %rcx shrq $63, %rcx sarq $34, %rax <- used to be "shrq $32, %rax; sarl $2, %eax" addl %ecx, %eax This fires 96 times in gcc.c on x86-64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124559 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-29Add the missing sub identity "A-(A-B) -> B" to DAGCombine.Benjamin Kramer
This happens e.g. for code like "X - X%10" where we lower the modulo operation to a series of multiplies and shifts that are then subtracted from X, leading to this missed optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124532 91177308-0d34-0410-b5e6-96231b3b80d8
