Subject: Adds a test for "disassemble -a" after an assert, which can fail with ELF
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cd20ee8369bbe04d2b8e677ca5fa6a3104b6f8bd;p=platform%2Fupstream%2Fllvm.git

Adds a test for "disassemble -a" after an assert, which can fail with ELF
because a synthetic symbol hasn't been provided for stripped function symbols.
