From 9bc898c7019383b6aa2ae6cb2928c4ca926449f0 Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Wed, 8 Jul 2015 10:04:02 +0000 Subject: perf tests: Add LLVM test for eBPF on-the-fly compiling Previous patches introduce llvm__compile_bpf() to compile source file to eBPF object. This patch adds testcase to test it. It also tests libbpf by opening generated object after applying next patch which introduces HAVE_LIBBPF_SUPPORT option. Since llvm__compile_bpf() prints long messages which users who don't explicitly test llvm doesn't care, this patch set verbose to -1 to suppress all debug, warning and error message, and hint user use 'perf test -v' to see the full output. For the same reason, if clang is not found in PATH and there's no [llvm] section in .perfconfig, skip this test.
