Bug ID: 37343
Summary: The SSE _mm_invsqrt_ps intrinsic is missing.
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Headers
Assignee: [email protected]
Reporter: [email protected]

The intel intrinsic guide
https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_mm_invsqrt_ps&expand=4513,3028,3028
Shows the intrinsic as:
__m128 _mm_invsqrt_ps (__m128 a)
#include <immintrin.h>
CPUID Flags: SSE
Description
Compute the inverse square root of packed single-precision (32-bit)
floating-point elements in a, and store the results in dst.
Operation
FOR j := 0 to 3
i := j*32
dst[i+31:i] := InvSQRT(a[i+31:i])
ENDFOR
dst[MAX:128] := 0
But it is not implemented in the clang headers.
