-Subject: [PATCH 2/3] perf clang: Fixes for more recent LLVM/clang
-
-The parameters to two functions and the location of a variable have
-changed in more recent LLVM/clang releases.
-
-Remove the unneecessary -fmessage-length and -ferror-limit flags, the
-former causes failures like:
-
-  58: builtin clang support                                           :
-  58.1: builtin clang compile C source to IR                          :
-  --- start ---
-  test child forked, pid 279307
-  error: unknown argument: '-fmessage-length'
-  1 error generated.
-  test child finished with -1
-
-Tested with LLVM 6, 8, 9, 10 and 11.
