From 9bdd5eb4c26e4a87b06c11363e193482d55aec5e Mon Sep 17 00:00:00 2001 From: Reid Kleckner Date: Tue, 9 Feb 2016 19:53:30 +0000 Subject: Pass /bigobj when building lib/ASTMatchers/Dynamic/Registry.cpp This is the third time it has crossed the 2^16 section limit. We've already spent time optimizing this file to reduce template instantiations, and it's not clear that there is anymore low hanging fruit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@260267 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ASTMatchers/Dynamic/CMakeLists.txt | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/lib/ASTMatchers/Dynamic/CMakeLists.txt b/lib/ASTMatchers/Dynamic/CMakeLists.txt index c0d80adaac..82c12a47fa 100644 --- a/lib/ASTMatchers/Dynamic/CMakeLists.txt +++ b/lib/ASTMatchers/Dynamic/CMakeLists.txt @@ -1,5 +1,14 @@ set(LLVM_LINK_COMPONENTS support) +# The registry source file ends up generating a lot of sections for each +# matcher.
