2013-03-31X86: Promote sitofp <8 x i16> to <8 x i32> when AVX is available.Benjamin Kramer
A vector sext + sitofp is a lot cheaper than 8 scalar conversions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178448 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-31Add the PPC lfiwax instructionHal Finkel
This instruction is available on modern PPC64 CPUs, and is now used to improve the SINT_TO_FP lowering (by eliminating the need for the separate sign extension instruction and decreasing the amount of needed stack space). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178446 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-31Cleanup PPC(64) i32 -> float/double conversionHal Finkel
The existing SINT_TO_FP code for i32 -> float/double conversion was disabled because it relied on broken EXTSW_32/STD_32 instruction definitions. The original intent had been to enable these 64-bit instructions to be used on CPUs that support them even in 32-bit mode. Unfortunately, this form of lying to the infrastructure was buggy (as explained in the FIXME comment) and had therefore been disabled. This re-enables this functionality, using regular DAG nodes, but only when compiling in 64-bit mode. The old STD_32/EXTSW_32 definitions (which were dead) are removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178438 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-30Add start of user documentation for NVPTXJustin Holewinski
Summary: This is the beginning of user documentation for the NVPTX back-end. I want to ensure I am integrating this properly into the rest of the LLVM documentation.

2013-03-30Change '@SECREL' suffix to GAS-compatible '@SECREL32'.Benjamin Kramer
'@SECREL' is what is used by the Microsoft assembler, but GNU as expects '@SECREL32'. With the patch, the MC-generated code works fine in combination with a recent GNU as (2.23.51.20120920 here).

2013-03-30[docs] Annotate mailing lists with their "name".Sean Silva
Nobody says "the developer's list" or "commits archive"; they always say "llvmdev" or "llvm-commits". It makes sense for our documentation to at least make that association explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178425 91177308-0d34-0410-b5e6-96231b3b80d8

specific code paths. This allows us to write code like: if (__nvvm_reflect("FOO")) // Do something else // Do something else and compile into a library, then give "FOO" a value at kernel compile-time so the check becomes a no-op. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178416 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-30Implement XOR reassociation. It is based on following rules:Shuxin Yang
rule 1: (x | c1) ^ c2 => (x & ~c1) ^ (c1^c2), only useful when c1=c2 rule 2: (x & c1) ^ (x & c2) = (x & (c1^c2)) rule 3: (x | c1) ^ (x | c2) = (x & c3) ^ c3 where c3 = c1 ^ c2 rule 4: (x | c1) ^ (x & c2) => (x & c3) ^ c1, where c3 = ~c1 ^ c2 It reduces an application's size (in terms of # of instructions) by 8.9%.

2013-03-29PNaCl: Fix ExpandTls to handle a couple of corner cases involving PHI nodesMark Seaborn
ExpandTls's use of replaceUsesOfWith() didn't work for PHI nodes containing the same Constant twice (which needs to work for same or differing incoming BasicBlocks). The same applies to ExpandTlsConstantExpr. I noticed this while implementing ExpandConstantExpr. Fix this and factor out some common code that all three passes can use.

2013-03-29[docs] The STL "binary search" has a non-obvious name.Sean Silva
std::lower_bound is the canonical "binary search" in the STL (std::binary_search generally is not what you want). The name actually makes a lot of sense (and also has a beautiful symmetry with the std::upper_bound algorithm). The name is nonetheless non-obvious. Also, remove mention of "radix search". It's not even clear how that would work in the context of a sorted vector. AFAIK "radix search" only makes sense when you have a trie-like data structure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178376 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-29Implement FRINT lowering on PPC using frinHal Finkel
Like nearbyint, rint can be implemented on PPC using the frin instruction. The complication comes from the fact that rint needs to set the FE_INEXACT flag when the result does not equal the input value (and frin does not do that). As a result, we use a custom inserter which, after the rounding, compares the rounded value with the original, and if they differ, explicitly sets the XX bit in the FPSCR register (which corresponds to FE_INEXACT). Once LLVM has better modeling of the floating-point environment we should be able to (often) eliminate this extra complexity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178362 91177308-0d34-0410-b5e6-96231b3b80d8
