| From | Wang Nan <> | Subject | [RFC PATCH v10 38/50] perf record: Add clang options for compiling BPF scripts | Date | Wed, 1 Jul 2015 02:14:26 +0000 |
| |
Although previous patch allows setting BPF compiler related options in perfconfig, on some ad-hoc situation it still requires passing options through cmdline. This patch introduces 2 options to 'perf record' for this propose: --clang-path and --clang-opt.
