From 2102df96a6176bc77c5da9d78f85c5d673106b2d Mon Sep 17 00:00:00 2001 From: Hans Wennborg Date: Mon, 9 Sep 2013 19:04:49 +0000 Subject: [PATCH] clang-cl: parse (but don't support) the /o flag Apparently folks run into this (PR17097). The flag is not supported by MSVC either, but we should parse it so we don't get confused when it occurs. This changes the clang-cl output for "clang-cl /c /o foo.obj" from: clang-cl.exe: error: no such file or directory: '/o' clang-cl.exe: error: no such file or directory: 'foo.obj' to: clang-cl.exe: warning: argument unused during compilation: '/o bajs.obj' llvm-svn: 190323 --- clang/include/clang/Driver/CLCompatOptions.td | 1 + clang/test/Driver/cl-options.c | 1 + 2 files changed, 2 insertions(+) diff --git a/clang/include/clang/Driver/CLCompatOptions.td b/clang/include/clang/Driver/CLCompatOptions.td index a520046..574830c 100644 --- a/clang/include/clang/Driver/CLCompatOptions.td +++ b/clang/include/clang/Driver/CLCompatOptions.td @@ -143,6 +143,7 @@ def _SLASH_Gy : CLFlag<"Gy">; def _SLASH_Gy_ : CLFlag<"Gy-">; def _SLASH_GZ : CLFlag<"GZ">; def _SLASH_MP : CLJoined<"MP">; +def _SLASH_o : CLJoinedOrSeparate<"o">; def _SLASH_w : CLJoined<"w">; def _SLASH_Za : CLFlag<"Za">; def _SLASH_Zc : CLJoined<"Zc:">; diff --git a/clang/test/Driver/cl-options.c b/clang/test/Driver/cl-options.c index dc33db6..ab0320c 100644 --- a/clang/test/Driver/cl-options.c +++ b/clang/test/Driver/cl-options.c @@ -107,6 +107,7 @@ // (/Zs is for syntax-only) // RUN: %clang_cl /Zs /EHsc /Fdfoo /fp:precise /Gd /GL /GL- -- %s 2>&1 // RUN: %clang_cl /Zs /Gm /Gm- /GS /Gy /Gy- /GZ -- %s 2>&1 +// RUN: %clang_cl /Zs /ofoo.obj /o foo.obj -- %s 2>&1 // RUN: %clang_cl /Zs /wfoo /Zc:wchar_t- -- %s 2>&1 // RUN: %clang_cl /Zs /ZI /Zi /MP -- %s 2>&1 -- 2.7.4
