Bug ID: 71659
Summary: _xgetbv intrinsic missing
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: andi-gcc at firstfloor dot org
Target Milestone: ---
icc and microsoft have a _xgetbv intrinsic for the XGETBV instruction, which is
needed to check if AVX or MPX are supported by the kernel.
gcc is missing an intrinsic for that, so everyone has to write inline
assembler. Should add one.
