--- Comment #129 from Kazumoto Kojima <kkojima at gcc dot gnu.org> ---
A reduced 2-line testcase for -O2 -fpic -mlra:
extern void bar (void) __attribute__ ((__noreturn__));
void foo (void) { bar (); }
Looks LRA reveals again pcrel call insn_and_splits scratch register allocation
problem. Maybe the similar issue with sibcall_vallue_pcrel which is commented
by Oleg at the just before that insn_and_split.
