Extended Description

arm_neon_intrinsics.c test has two problems. The last change to this test was in r263048. This test is marked "REQUIRES: long_tests" which hides this test from most configs.

1) The RUN line is incorrect: // RUN: %clang_cc1 -triple thumbv7s-apple-darwin -target-abi apcs-gnu\ // RUN: -target-cpu swift -ffreestanding -emit-llvm -S -o - %s\ // RUN: opt -S -mem2reg | FileCheck %s Clang doesn't need the -S flag, and opt is an argument to Clang due to a missing pipe. This is fixed to: // RUN: %clang_cc1 -triple thumbv7s-apple-darwin -target-abi apcs-gnu\ // RUN: -target-cpu swift -ffreestanding -emit-llvm -o - %s\ // RUN: | opt -S -mem2reg | FileCheck %s

2) Even with the fixed RUN line, the FileCheck fails due to multiple errors. Here is the start of it:

Should be fixed and re-enabled by r263093. Let me know if you have any problems, and sorry about the breakage.

[TNorthover]

(And thanks for taking care of the temporary workaround).

[TNorthover]

Ouch, that's really rather scary. Working on a fix now.

[Weverything]

The RUN lines are fixed and the FileCheck portion is disabled in r263091.
