ia64-2.C   [plain text]

// PR target/30230
// This testcase failed on IA-64, where end of an EH region ended
// in the middle of a bundle (with br.call insn in first or second
// slot of .bbb/.mbb bundles and EH region end right after it).
// But br.call returns to the start of the next bundlem so during
// unwinding the call was considered to be outside of the EH region
// while it should have been inside.
// { dg-options "-O2" }
// { dg-do run }
