From 6433f7c84d68039000785d818b2f139354a26f8c Mon Sep 17 00:00:00 2001 From: Reid Kleckner Date: Tue, 1 Jul 2014 22:23:54 +0000 Subject: [PATCH] Win64: Disable uwtable until we fix .pdata emission in LLVM LLVM r211399 started emitting .pdata for win64 by default. Unfortunately, it produces invalid object files. I plan to fix that Soon. For now, don't request unwind tables. This fixes the clang-cl self-host on win64. llvm-svn: 212137 --- clang/lib/Driver/WindowsToolChain.cpp | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/clang/lib/Driver/WindowsToolChain.cpp b/clang/lib/Driver/WindowsToolChain.cpp index a1ba7a7..913425a 100644 --- a/clang/lib/Driver/WindowsToolChain.cpp +++ b/clang/lib/Driver/WindowsToolChain.cpp @@ -59,7 +59,11 @@ bool Windows::IsIntegratedAssemblerDefault() const { } bool Windows::IsUnwindTablesDefault() const { - return getArch() == llvm::Triple::x86_64; + // FIXME: LLVM's lowering of Win64 data is broken right now.
