[llvm-commits] llvm-gcc: always create a call to eh.selector, even if there are no type infos

[Duncan Sands]

A function that only has cleanups (destructors) to run when an exception is raised
currently is not assigned a personality function because we don't bother creating
a call to eh.selector if there are no catches.  But the personality function is
still needed, since it is the personality function that analyses the exception table
and decides where to jump to (to the cleanups in this case).  This patch causes a
call to eh.selector to be generated in every landing pad, even if it has no type infos,
because that specifies the personality function.

Ciao,

Duncan.
