            Bug ID: 16296
           Summary: fegetround is pure?
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: marc.glisse at normalesup dot org

I could be wrong, but it seems that the function fegetround could get
__attribute_pure__, since it only reads a global state, and in particular the
usual optimizations (remove it if the result is unused, reuse the result from
the first call when there are two calls in a row) should be fine.
