From a5969ce15f79622b5c5ea399e05c4606fda99074 Mon Sep 17 00:00:00 2001 From: Justin Bogner Date: Thu, 12 Oct 2017 01:57:49 +0000 Subject: llvm-isel-fuzzer: Handle a subset of backend flags in the executable name Here we add a secondary option parser to llvm-isel-fuzzer (and provide it for use with other fuzzers). With this, you can copy the fuzzer to a name like llvm-isel-fuzzer:aarch64-gisel for a fuzzer that fuzzer AArch64 with GlobalISel enabled, or fuzzer:x86_64 to fuzz x86, with no flags required. This should be useful for running these in OSS-Fuzz. Note that this handrolls a subset of cl::opts to recognize, rather than embedding a complete command parser for argv[0]. If we find we really need the flexibility of handling arbitrary options at some point we can rethink this. llvm-svn: 315545 --- llvm/tools/llvm-isel-fuzzer/llvm-isel-fuzzer.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'llvm/tools/llvm-isel-fuzzer/llvm-isel-fuzzer.cpp') diff --git a/llvm/tools/llvm-isel-fuzzer/llvm-isel-fuzzer.cpp b/llvm/tools/llvm-isel-fuzzer/llvm-isel-fuzzer.cpp index 314acdb5087..164c85f9516 100644 --- a/llvm/tools/llvm-isel-fuzzer/llvm-isel-fuzzer.cpp +++ b/llvm/tools/llvm-isel-fuzzer/llvm-isel-fuzzer.cpp @@ -150,6 +150,7 @@ extern "C" LLVM_ATTRIBUTE_USED int LLVMFuzzerInitialize(int *argc, InitializeAllAsmPrinters(); InitializeAllAsmParsers(); + handleExecNameEncodedBEOpts(*argv[0]); parseFuzzerCLOpts(*argc, *argv); if (TargetTriple.empty()) { -- cgit v1.2.3
