* [X86] Improve the selection of SSE3/AVX addsub instructions. Andrea Di Biagio2014-06-261-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | This patch teaches the backend how to canonicalize a shuffle vectors according to the rule: - (shuffle (FADD A, B), (FSUB A, B), Mask) -> (shuffle (FSUB A, -B), (FADD A, -B), Mask) Where 'Mask' is: <0,5,2,7> ;; for v4f32 and v4f64 shuffles. <0,3> ;; for v2f64 shuffles. <0,9,2,11,4,13,6,15> ;; for v8f32 shuffles. In general, ISel only knows how to pattern-match a canonical 'fadd + fsub + blendi' dag node sequence into an ADDSUB instruction. This new rule allows to convert a non-canonical dag sequence into a canonical one that will be matched by a single ADDSUB at ISel stage. The idea of converting a non-canonical ADDSUB into a canonical one by swapping the first two operands of the shuffle, and then negating the second operand of the FADD and FSUB, was originally proposed by Hal Finkel. llvm-svn: 211771

* Introduce a string_ostream string builder faciltyAlp Toker2014-06-2643-224/+155
| | | | | | | | | | | | | | | | | | | | string_ostream is a safe and efficient string builder that combines opaque stack storage with a built-in ostream interface. small_string_ostream<bytes> additionally permits an explicit stack storage size other than the default 128 bytes to be provided. Beyond that, storage is transferred to the heap. This convenient class can be used in most places an std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair would previously have been used, in order to guarantee consistent access without byte truncation. The patch also converts much of LLVM to use the new facility. These changes include several probable bug fixes for truncated output, a programming error that's no longer possible with the new interface. llvm-svn: 211749

This can happen when one of the operands to the cmp is a load and the load gets folded into the cmp. In this case FastISel will skip the load instruction and the vreg is never defined. llvm-svn: 211730

| | | | | | | | | | | | | | | | | | the call itself has no debug location. This situation does bad things when inlined, so I've fixed Clang not to produce inlinable call sites without locations when the caller has debug info (in the one case where I could find that this occurred). This updates the PR20038 test case to be what clang now produces, and readds the assertion that had to be removed due to this bug. I've also beefed up the debug info verifier to help diagnose these issues in the future, and I hope to add checks to the inliner to just assert-fail if it encounters this situation. If, in the future, we decide we have to cope with this situation, the right thing to do is probably to just remove all the DebugLocs from the inlined instructions. llvm-svn: 211723

* [X86] Always prefer to lower a VECTOR_SHUFFLE into a BLENDI instead of SHUFP ↵Andrea Di Biagio2014-06-252-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | (or VPERM2X128). This patch teaches method 'LowerVECTOR_SHUFFLE' to give higher precedence to the check for 'isBlendMask'; the idea is that, when possible, we should firstly check if a shuffle performs a blend, and in case, try to lower it into a BLENDI instead of selecting a SHUFP or (worse) a VPERM2X128. In general: - AVX VBLENDPS/D always have better latency and throughput than VPERM2F128; - BLENDPS/D instructions tend to always have better 'reciprocal throughput' than the equivalent SHUFPS/D; - Both BLENDPS/D and SHUFPS/D are often decoded into the same number of m-ops; however, a m-op obtained from a BLENDPS/D can be scheduled to more than one execution port. This patch: - Moves the check for 'isBlendMask' immediately before the check for 'isSHUFPMask' within method 'LowerVECTOR_SHUFFLE'; - Updates existing tests for sse/avx shuffle/blend instructions to verify that we select (v)blendps/d when possible (instead of (v)shufps/d or vperm2f128). llvm-svn: 211720

| | | | | | | | | | | | | | | | | | | [LLVM part] These patches rename the loop unrolling and loop vectorizer metadata such that they have a common 'llvm.loop.' prefix. Metadata name changes: llvm.vectorizer.* => llvm.loop.vectorizer.* llvm.loopunroll.* => llvm.loop.unroll.* This was a suggestion from an earlier review (http://reviews.llvm.org/D4090) which added the loop unrolling metadata.

* Random Number Generator (llvm)JF Bastien2014-06-253-1/+76
| | | | | | | | | | | | | | | | | | | | | | | | Provides an abstraction for a random number generator (RNG) that produces a stream of pseudo-random numbers. The current implementation uses C++11 facilities and is therefore not cryptographically secure. The RNG is salted with the text of the current command line invocation. In addition, a user may specify a seed (reproducible builds). In clang, the seed can be set via -frandom-seed=X In the back end, the seed can be set via -rng-seed=X This is the llvm part of the patch. clang part: D3391 URL: http://reviews.llvm.org/D3390 Author: yln I'm landing this for the second time, it broke Windows bots the first time around. llvm-svn: 211705

| | | | | | | | | | | | | | | | | | | | | | | ignore SEH pseudo ops in X86 JIT emitter. -- This patch enables LLVM to emit Win64-native unwind info rather than DWARF CFI. It handles all corner cases (I hope), including stack realignment. Because the unwind info is not flexible enough to describe stack frames with a gap of unknown size in the middle, such as the one caused by stack realignment, I modified register spilling code to place all spills into the fixed frame slots, so that they can be accessed relative to the frame pointer.
