           Summary: __builtin_trap doesn't trap
           Product: tools
           Version: 2.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: llvm-gcc
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: djg at cray.com
                CC: llvmbugs at cs.uiuc.edu


This C testcase:

void foo(void) { __builtin_trap(); }

is compiled by llvm-gcc into

define void @foo() {
entry:
        ret void
}

In otherwords, __builtin_trap() is treated as a no-op.
