; BB cluster section test for exception handling.

; Test1: Basic blocks #1 and #3 are landing pads and must be in the same section.
; Basic block 2 will be placed in a unique section, but #1 and #3 are placed in the special exception section.
; The rest will be placed in a section along with the entry basic block.
; RUN: echo '!main' > %t1

; Test2: Basic blocks #1, #2, and #3 go into a separate section.
; No separate exception section will be created as #1 and #3 are already in one section.
