; RUN: llc -march=x86-64 -print-machineinstrs=expand-isel-pseudos %s -o /dev/null 2>&1 | FileCheck %s

; Check if the edge weight to the catchpad is calculated correctly.

; CHECK: Successors according to CFG: BB#2(0x7ffff100 / 0x80000000 = 100.00%) BB#1(0x00000800 / 0x80000000 = 0.00%) BB#3(0x00000400 / 0x80000000 = 0.00%) BB#4(0x00000200 / 0x80000000 = 0.00%) BB#5(0x00000100 / 0x80000000 = 0.00%)
