Raw Normal View History

A lot of changes were suggested by Chris. ExecveHandler.c: * Use "" instead of <> for LLVM include files * Use raw I/O, we don't need buffering * Set errno = 0 before using open() * strlen() doesn't count NULL terminator in its size * Use memcmp() instead of strcmp() * Return result of the real execve(), not 0 * Search for path to bytecode file if not absolute/relative path SysUtils.c: * Convert all comments to C-style * Stop using `bool', use `unsigned' instead SysUtils.h: * Stop using `bool', use `unsigned' instead * Updated comment to FindExecutable() README.txt: * Describe the goal of LLEE and an application git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7911 91177308-0d34-0410-b5e6-96231b3b80d8
