* [vectorizer] Tweak the way we do small loop runtime unrolling in theChandler Carruth2014-01-31
| | | | | | | | | | | | | | loop vectorizer to not do so when runtime pointer checks are needed and share code with the new (not yet enabled) load/store saturation runtime unrolling. Also ensure that we only consider the runtime checks when the loop hasn't already been vectorized. If it has, the runtime check cost has already been paid. I've fleshed out a test case to cover the scalar unrolling as well as the vector unrolling and comment clearly why we are or aren't following the pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200530 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in gcov instrumentation introduced by r195513. <rdar://15930350>Bob Wilson2014-01-31
| | | | | | | | | | The entry block of a function starts with all the static allocas. The change in r195513 splits the block before those allocas, which has the effect of turning them into dynamic allocas. That breaks all sorts of things. Change to split after the initial allocas, and also add a comment explaining why the block is split. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200515 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | when the input is a concat_vectors and the insert replaces one of the concat halves: Lower half: fold (insert_subvector (concat_vectors X, Y), Z) -> (concat_vectors Z, Y) Upper half: fold (insert_subvector (concat_vectors X, Y), Z) -> (concat_vectors X, Z) This can be seen with the following IR: define <8 x float> @lower_half(<4 x float> %v1, <4 x float> %v2, <4 x float> %v3) { %1 = shufflevector <4 x float> %v1, <4 x float> %v2, <8 x i32> <i32 0, i32 1, i32 2, i32 3, i32 4, i32 5, i32 6, i32 7> %2 = tail call <8 x float> @llvm.x86.avx.vinsertf128.ps.256(<8 x float> %1, <4 x float> %v3, i8 0) The vinsertf128 intrinsic is converted into an insert_subvector node in SelectionDAGBuilder.cpp. Using AVX, without the patch this generates two vinsertf128 instructions: vinsertf128 $1, %xmm1, %ymm0, %ymm0 vinsertf128 $0, %xmm2, %ymm0, %ymm0 With the patch this is optimized into: vinsertf128 $1, %xmm1, %ymm2, %ymm0 Patch by Robert Lougher. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200506 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | When converting from "or + br" to two branches, or converting from "and + br" to two branches, we correctly update the edge weights of the two branches. The previous attempt at r200431 was reverted at r200434 because of two testing case failures. I modified my patch a little, but forgot to re-run "make check-all". Testing case CodeGen/ARM/lsr-unfolded-offset.ll is updated because of the patch's impact on branch probability which causes changes in spill placement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200502 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM IAS: support .object_archSaleem Abdulrasool2014-01-30
| | | | | | | | | | The .object_arch directive indicates an alternative architecture to be specified in the object file. The directive does *not* effect the enabled feature bits for the object file generation. This is particularly useful when the code performs runtime detection and would like to indicate a lower architecture as the requirements than the actual instructions used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200451 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM IAS: support .movspSaleem Abdulrasool2014-01-30
| | | | | | | | .movsp is an ARM unwinding directive that indicates to the unwinder that a register contains an offset from the current stack pointer.

* ARM: suuport .tlsdescseq directiveSaleem Abdulrasool2014-01-30
| | | | | | | | | | | This enhances the ARMAsmParser to handle .tlsdescseq directives. This is a slightly special relocation. We must be able to generate them, but not consume them in assembly. The relocation is meant to assist the linker in generating a TLS descriptor sequence. The ELF target streamer is enhanced to append additional fixups into the current segment and that is used to emit the new R_ARM_TLS_DESCSEQ relocations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200448 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: support TLS descriptor relocationsSaleem Abdulrasool2014-01-30

* ARM: support tlscall relocationsSaleem Abdulrasool2014-01-30
| | | | | | | | | | | | | | This adds support for TLS CALL relocations. TLS CALL relocations are used to indicate to the linker to generate appropriate entries to resolve TLS references via an appropriate function invocation (e.g. __tls_get_addr(PLT)). In order to accomodate the linker relaxation of the TLS access model for the references (GD/LD -> IE, IE -> LE), the relocation addend must be incomplete. This requires that the partial inplace value is also incomplete (i.e. 0). We simply avoid the offset value calculation at the time of the fixup adjustment in the ARM assembler backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200446 91177308-0d34-0410-b5e6-96231b3b80d8
