From 16953b5cfa040c886d0edfbf2f4da478c3e6014d Mon Sep 17 00:00:00 2001 From: David Carlier Date: Wed, 30 Oct 2019 17:04:43 +0000 Subject: LLVM mode passing the full path of the LLVM config bindir. On FreeBSD the system compiler does not have llvm-config however system packages provides several version of the LLVM toolchain thus forcing to pass AFL_CC/AFL_CXX to make it work fully. --- llvm_mode/afl-clang-fast.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'llvm_mode/afl-clang-fast.c') diff --git a/llvm_mode/afl-clang-fast.c b/llvm_mode/afl-clang-fast.c index 1acf8856..e92fb76f 100644 --- a/llvm_mode/afl-clang-fast.c +++ b/llvm_mode/afl-clang-fast.c @@ -32,11 +32,13 @@ #include #include #include +#include #include static u8* obj_path; /* Path to runtime libraries */ static u8** cc_params; /* Parameters passed to the real CC */ static u32 cc_par_cnt = 1; /* Param count, including argv0 */ +static u8 llvm_fullpath[PATH_MAX]; /* Try to find the runtime libraries.
