From 022829d84c2c4e992980bf99695bea4be5c31ef1 Mon Sep 17 00:00:00 2001 From: Hans Wennborg Date: Thu, 12 Oct 2017 03:32:09 +0000 Subject: Revert r315545 "llvm-isel-fuzzer: Handle a subset of backend flags in the executable name" It broke some tests on Windows: Failing Tests (4): LLVM :: tools/llvm-isel-fuzzer/execname-options.ll LLVM :: tools/llvm-isel-fuzzer/missing-triple.ll LLVM :: tools/llvm-isel-fuzzer/x86-empty-bc.ll LLVM :: tools/llvm-isel-fuzzer/x86-empty.ll > 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: 315554 --- llvm/docs/FuzzingLLVM.rst | 7 ------- 1 file changed, 7 deletions(-) (limited to 'llvm/docs/FuzzingLLVM.rst') diff --git a/llvm/docs/FuzzingLLVM.rst b/llvm/docs/FuzzingLLVM.rst index 5ba5fa10b67..ef7b2138326 100644 --- a/llvm/docs/FuzzingLLVM.rst +++ b/llvm/docs/FuzzingLLVM.rst @@ -81,13 +81,6 @@ the following command would fuzz AArch64 with :doc:`GlobalISel`: % bin/llvm-isel-fuzzer -ignore_remaining_args=1 -mtriple aarch64 -global-isel -O0 -Some flags can also be specified in the binary name itself in order to support -OSS Fuzz, which has trouble with required arguments.
