Without this we would get library calls for fused-multiply-add even if it's available in hardware. - Add openmp-drop-rpath.patch: backport revert of adding RUNPATH to openmp executables.

Subject: [PATCH] Revert D118493 "Set rpath on openmp executables"
|
|
|
|
This reverts commit 9b9d08111b618d74574ba03e5cc3d752ecc56f55.
|
|
(Accepted by Jon https://reviews.llvm.org/D118493#4178250)
|
|
|
|
libc++, libc++abi, libunwind, and compiler-rt don't add the extra DT_RUNPATH,
|
|
it's strange for OpenMP to diverge.
|
|
Some build systems want to handle DT_RUNPATH themselves (e.g.
|
|
CMAKE_INSTALL_RPATH). Some distributions (e.g. Fedora) have policies against
|
|
DT_RUNPATH and the default DT_RUNPATH for OpenMP is causing trouble.
|
|
|
|
For users who don't want to specify rpath by themselves,
|
|
https://clang.llvm.org/docs/UsersManual.html#configuration-files
|
|
can be used to specify the default rpath, e.g.
|
|
specify -frtlib-add-rpath or -Wl,-rpath in bin/clang.cfg
