Bug ID: 94046
Summary: cast to __m256d in mask argument of avx2 float gather
intrinsics
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: niklas at nolte dot dev
Target Milestone: ---
I cannot call the _mm256_mask_i32gather_ps intrinsic with a mask argument that
is not implicitly convertible to __mm256d, only in -O0 mode.
Please correct me if i'm misunderstanding, but it seems like the cast to
__m256d for the mask argument is a mistake.
