Bug ID: 15654
Summary: Fallback fenv.h functions fail inappropriately
Product: glibc
Version: 2.17
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
The fallback implementations of various <fenv.h> functions in math/f*.c fail in
various cases where the function is really a no-op for software floating point
without exceptions or rounding modes, and so should succeed. The approach
taken for Tile, where various functions act as no-ops and succeed, is more
appropriate.
Testing a patch.
