Summary: FAIL: gcc.c-torture/execute/builtins/abs-2.c
execution, -O2 -flto
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: amo...@gmail.com

compile with -w -O2 -m32 -flto abs-2.i abs-2-lib.i main.i -lm
Fails due to "bl main_test" branching to a bogus location. This is because the
only definition for main_test is one from the IR file, and ld doesn't check
that the symbol has been replaced with a real one. With the patch in
http://sourceware.org/ml/binutils/2011-02/msg00037.html we get a linker error.
Reversing the order of inputs..
