llvm-mirror/test/Assembler/attribute-builtin.ll
Richard Smith 8f327c0a19 Remove verifier check that attribute 'builtin' is only applied to calls to
functions marked 'nobuiltin'. That approach doesn't play well with LTO, and
there's no harm in marking a call as 'builtin' if it was going to be a builtin
regardless.
