            Bug ID: 27475
           Summary: Incorrect IFUNC selector for wcschr and strchrnul
           Product: glibc
           Version: 2.34
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---
            Target: x86-64

There are

strchrnul-avx2.S:#include "strchr-avx2.S"
wcschr-avx2.S:#include "strchr-avx2.S"

strchr-avx2.S uses

sarxl %ecx, %eax, %eax

which is in BMI2.  But IFUNC selector for wcschr and strchrnul doesn't
check for BMI2.
