This patch adds support for the compiler-rt (CLANG runtime) library. It builds a set of static libraries and installs them into the CLANG/LLVM toolchain resource folder. Signed-off-by: Matthew Weber <matthew.weber@rockwellcollins.com> Cc: Romain Naour <romain.naour@smile.fr> Cc: Ricardo Martincoski <ricardo.martincoski@gmail.com> Cc: Valentin Korenblit <valentinkorenblit@gmail.com> --- Changes v1 -> v2 [Romain - Removed unnecessary host-cmake dependency v2 -> v3 [Romain - Update to use COMPILER_RT_INSTALL_PATH for library install [Ricardo - Fixed check-package extra line - Spelling in commit message v3 -> v4 [Valentin - Pointed out that non-glibc libraries won't build. Further investigation shows that the lib asan support in compiler-rt doesn't have the libc checks yet to support multiple libraries. (https://patchwork.ozlabs.org/patch/339938/ was the best example I could find and it doesn't look like anything has changed in the recent codebase) v4 -> v5 [Thomas P - Revisited staging install step and found a cleaner way to use the default and then a hook to setup the runtime library path --- DEVELOPERS | 1 + package/Config.in | 1 + package/compiler-rt/Config.in | 14 ++++++++++++++ package/compiler-rt/compiler-rt.hash | 3 +++ package/compiler-rt/compiler-rt.mk | 34 ++++++++++++++++++++++++++++++++++ 5 files changed, 53 insertions(+) create mode 100644 package/compiler-rt/Config.in create mode 100644 package/compiler-rt/compiler-rt.hash create mode 100644 package/compiler-rt/compiler-rt.mk
