    [PATCH] ia64: Save/Restore of IA32 fpstate in sigcontext · c52f1179
    Venkatesh Pallipadi authored
    The IA32 fpstate information is not getting saved/restored during IA32
    exception handling. The issue was first observed due to an IA32 binary
    (which runs fine on IA32 system), failing on Itanium based system. The
    binary was trying to access the fpstate information during an FPE and got a
    SEGV, as the fpstate was not getting saved and the sigcontext->fpstate
    pointer was NULL.
