[PowerPC] Temporarily disable VSX for PowerPC fast-isel tests Patch by Bill Seurer; some comment formatting changes by me. There are a few PowerPC test cases for FastISel support that currently fail with VSX support enabled. The temporary workaround under discussion in http://reviews.llvm.org/D5362 helps, but the tests still fail because they specify -fast-isel-abort, and the VSX workaround punts back to SelectionDAG. We have plans to fix FastISel permanently for VSX, but until that's in place these tests are preventing us from enabling VSX by default. Therefore we are adding -mattr=-vsx to these tests until the full support is ready. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220172 91177308-0d34-0410-b5e6-96231b3b80d8

; FIXME: FastISel currently returns false if it hits code that uses VSX
; registers and with -fast-isel-abort turned on the test case will then fail.
; When fastisel better supports VSX fix up this test case.

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction) PR20071 identifies a problem in PowerPC's fast-isel implementation for floating-point conversion to integer. The fctiduz instruction was added in Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being generated regardless of which 64-bit PowerPC target is selected. The intent is for fast-isel to punt to DAG selection when this instruction is not available. This patch implements that change. For testing purposes, the existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests for the expected code generation. Additionally, the existing test fast-isel-conversion-p5.ll was found to be incorrectly expecting the unavailable instruction to be generated. I've removed these test variants since we have adequate coverage in fast-isel-conversion.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211627 91177308-0d34-0410-b5e6-96231b3b80d8

Fix bug in GPR to FPR moves in PPC64LE. The current implementation of GPR->FPR register moves uses a stack slot. This mechanism writes a double word and reads a word. In big-endian the load address must be displaced by 4-bytes in order to get the right value. In little endian this is no longer required. This patch fixes the issue and adds LE regression tests to fast-isel-conversion which currently expose this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219441 91177308-0d34-0410-b5e6-96231b3b80d8

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction) PR20071 identifies a problem in PowerPC's fast-isel implementation for floating-point conversion to integer. The fctiduz instruction was added in Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being generated regardless of which 64-bit PowerPC target is selected. The intent is for fast-isel to punt to DAG selection when this instruction is not available. This patch implements that change. For testing purposes, the existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests for the expected code generation.

Fix bug in GPR to FPR moves in PPC64LE. The current implementation of GPR->FPR register moves uses a stack slot. This mechanism writes a double word and reads a word. In big-endian the load address must be displaced by 4-bytes in order to get the right value. In little endian this is no longer required. This patch fixes the issue and adds LE regression tests to fast-isel-conversion which currently expose this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219441 91177308-0d34-0410-b5e6-96231b3b80d8

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction) PR20071 identifies a problem in PowerPC's fast-isel implementation for floating-point conversion to integer. The fctiduz instruction was added in Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being generated regardless of which 64-bit PowerPC target is selected. The intent is for fast-isel to punt to DAG selection when this instruction is not available. This patch implements that change. For testing purposes, the existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests for the expected code generation. Additionally, the existing test fast-isel-conversion-p5.ll was found to be incorrectly expecting the unavailable instruction to be generated. I've removed these test variants since we have adequate coverage in fast-isel-conversion.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211627 91177308-0d34-0410-b5e6-96231b3b80d8

Fix bug in GPR to FPR moves in PPC64LE. The current implementation of GPR->FPR register moves uses a stack slot. This mechanism writes a double word and reads a word. In big-endian the load address must be displaced by 4-bytes in order to get the right value. In little endian this is no longer required. This patch fixes the issue and adds LE regression tests to fast-isel-conversion which currently expose this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219441 91177308-0d34-0410-b5e6-96231b3b80d8

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction) PR20071 identifies a problem in PowerPC's fast-isel implementation for floating-point conversion to integer. The fctiduz instruction was added in Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being generated regardless of which 64-bit PowerPC target is selected. The intent is for fast-isel to punt to DAG selection when this instruction is not available. This patch implements that change. For testing purposes, the existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests for the expected code generation. Additionally, the existing test fast-isel-conversion-p5.ll was found to be incorrectly expecting the unavailable instruction to be generated. I've removed these test variants since we have adequate coverage in fast-isel-conversion.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211627 91177308-0d34-0410-b5e6-96231b3b80d8

In big-endian the load address must be displaced by 4-bytes in order to get the right value. In little endian this is no longer required. This patch fixes the issue and adds LE regression tests to fast-isel-conversion which currently expose this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219441 91177308-0d34-0410-b5e6-96231b3b80d8

[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction) PR20071 identifies a problem in PowerPC's fast-isel implementation for floating-point conversion to integer. The fctiduz instruction was added in Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being generated regardless of which 64-bit PowerPC target is selected. The intent is for fast-isel to punt to DAG selection when this instruction is not available. This patch implements that change. For testing purposes, the existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests for the expected code generation. Additionally, the existing test fast-isel-conversion-p5.ll was found to be incorrectly expecting the unavailable instruction to be generated. I've removed these test variants since we have adequate coverage in fast-isel-conversion.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211627 91177308-0d34-0410-b5e6-96231b3b80d8

[PowerPC] Add handling for conversions to fast-isel. Yet another chunk of fast-isel code. This one handles various conversions involving floating-point. (It also includes some miscellaneous handling throughout the back end for LWA_32 and LWAX_32 that should have been part of the load-store patch.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189677 91177308-0d34-0410-b5e6-96231b3b80d8
