From ae229d599b8ccf5475fbdf2459fc54f2cce3dec7 Mon Sep 17 00:00:00 2001 From: Chad Rosier Date: Tue, 29 Jan 2013 23:31:22 +0000 Subject: [ubsan] Implement the -fcatch-undefined-behavior flag using a trapping implementation; this is much more inline with the original implementation (i.e., pre-ubsan) and does not require run-time library support. The trapping implementation can be invoked using either '-fcatch-undefined-behavior' or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter being preferred. Eventually, the -fcatch-undefined-behavior' flag will be removed. llvm-svn: 173848 --- clang/lib/Frontend/CompilerInvocation.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'clang/lib/Frontend/CompilerInvocation.cpp') diff --git a/clang/lib/Frontend/CompilerInvocation.cpp b/clang/lib/Frontend/CompilerInvocation.cpp index b200637..245de34 100644 --- a/clang/lib/Frontend/CompilerInvocation.cpp +++ b/clang/lib/Frontend/CompilerInvocation.cpp @@ -392,6 +392,8 @@ static bool ParseCodeGenArgs(CodeGenOptions &Opts, ArgList &Args, InputKind IK, Args.hasArg(OPT_fsanitize_memory_track_origins); Opts.SanitizeAddressZeroBaseShadow = Args.hasArg(OPT_fsanitize_address_zero_base_shadow); + Opts.SanitizeUndefinedTrapOnError = + Args.hasArg(OPT_fsanitize_undefined_trap_on_error); Opts.SSPBufferSize = Args.getLastArgIntValue(OPT_stack_protector_buffer_size, 8, Diags); Opts.StackRealignment = Args.hasArg(OPT_mstackrealign); -- cgit v1.1
