Subject: Add abort() as a builtin.  This has two effects: one, we warn for incorrect
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=772494c3b8f0c7c80484d0fef5b20cf4e445a8e2;p=clang

Add abort() as a builtin.  This has two effects: one, we warn for incorrect
declarations of abort(), and two, we mark it noreturn.  Missing the latter
shows up in one of the "embarassing" tests (from the thread on llvmdev
"detailed comparison of generated code size for LLVM and other compilers").
