Bug #: 14908
Summary: ARM setjmp/longjmp wrongly save/restore floating-point
flags
Product: glibc
Version: 2.16
Status: NEW
Severity: normal
Priority: P2
Component: ports
AssignedTo: unassigned@sourceware.org
ReportedBy: jsm28@gcc.gnu.org
CC: carlos@systemhalted.org, roland@gnu.org
Classification: Unclassified
The ARM implementation of setjmp and longjmp wrongly saves and restores fpscr -
but saving and restoring floating-point exceptions and rounding modes is
contrary to the requirements of C99 and C11. fpscr should not be saved and
restored, and there should be an architecture-independent testcase to verify
that exceptions and rounding modes are the same on the second return from
setjmp as they were when longjmp was called, not the same as on the original
call to setjmp.
