kernels in anonymous name space needs to have unique name to avoid duplicate symbols. Fixes: llvm#54560 Reviewed by: Artem Belevich Differential Revision: https://reviews.llvm.org/D123353 (cherry picked from commit 4ea1d43)
This patch is a continuation of https://reviews.llvm.org/D123353. Not only kernels in anonymous namespace, but also template kernels with template arguments in anonymous namespace need to be externalized. To be more generic, this patch checks the linkage of a kernel assuming the kernel does not have __global__ attribute. If the linkage is internal then clang will externalize it. This patch also fixes the postfix for externalized symbol since nvptx does not allow '.' in symbol name.

@tstellar, I've updated the branch accordingly. GitHub says I need "a maintainer to approve running workflows" -- could you please do that? I expect all tests should pass this time. #187 is a duplicate of my pull request, opened by @yxsamliu. It still has the ABI incompatibility and can thus probably be closed. |
