From f10bb0bfdcb2d549f00a0608b0a60160e41007a6 Mon Sep 17 00:00:00 2001 From: Louis Dionne Date: Thu, 7 Nov 2024 14:05:08 -0500 Subject: [PATCH] [libc++] Define all CMake configuration features in the same location This moves the configuration of the CMake features to turn off RTTI, exceptions and friends to the beginning of the CMake file, where we configure other optional parts of the library. This fixes an important bug where we would disable the benchmarks because these options were not defined yet, leading to the build thinking they were defined to OFF. --- libcxx/CMakeLists.txt | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/libcxx/CMakeLists.txt b/libcxx/CMakeLists.txt index d699135774ee0..abe12c2805a7c 100644 --- a/libcxx/CMakeLists.txt +++ b/libcxx/CMakeLists.txt @@ -47,6 +47,10 @@ include(HandleCompilerRT) # Basic options --------------------------------------------------------------- option(LIBCXX_ENABLE_SHARED "Build libc++ as a shared library."
