Bug ID: 28761
Summary: unused variable '__O' in avx512fintrin.h
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Headers
Assignee: unassignedclangb...@nondot.org
Reporter: lon...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
In https://llvm.org/svn/llvm-project/cfe/trunk/lib/Headers/avx512fintrin.h
static __inline__ __m256i __DEFAULT_FN_ATTRS
_mm512_cvtsepi64_epi32 (__m512i __A)
{
__v8si __O;
return (__m256i) __builtin_ia32_pmovsqd512_mask ((__v8di) __A,
(__v8si) _mm256_undefined_si256 (),
(__mmask8) -1);
}
__O is not used. This is annoying when compiling with -Werror:
clang/intrinsics/avx512fintrin.h:7505:10: error: unused variable '__O'
[-Werror,-Wunused-variable]
__v8si __O;
^
1 error generated.
This is present in 3.9.0 and trunk.
