Author: cbieneman Date: Tue Aug 23 15:07:07 2016 New Revision: 279559 URL: http://llvm.org/viewvc/llvm-project?rev=279559&view=rev Log: driver: Support checking for rlimits via cmake (when bootstrapping)
Summary: Add a cmake check for sys/resource.h and replace the __has_include() check with its result, in order to make it possible to use rlimits when building with compilers not supporting __has_include() -- i.e. when bootstrapping. // Please also re-apply dfcd52eb1d8e5d322404b40414cb7331c7380a8c (llvm-config.h fix) Patch by: Michał Górny Reviewers: rsmith, beanz Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D23744 Modified: cfe/trunk/CMakeLists.txt cfe/trunk/include/clang/Config/config.h.cmake cfe/trunk/tools/driver/cc1_main.cpp Modified: cfe/trunk/CMakeLists.txt URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/CMakeLists.txt?rev=279559&r1=279558&r2=279559&view=diff ============================================================================== --- cfe/trunk/CMakeLists.txt (original) +++ cfe/trunk/CMakeLists.txt Tue Aug 23 15:07:07 2016 @@ -177,6 +177,9 @@ if (LIBXML2_FOUND) set(CLANG_HAVE_LIBXML 1) endif() +include(CheckIncludeFile) +check_include_file(sys/resource.h CLANG_HAVE_RLIMITS) + set(CLANG_RESOURCE_DIR "" CACHE STRING "Relative directory from the Clang binary to its resource files.")
