This patch series is an updated and reworked version of some of the patch set posted about a year ago (the other features will be posted soon), this time supporting amdgcn, in addition to nvptx:
https://patchwork.sourceware.org/project/gcc/list/?series=10748&state=%2A&archive=both The series implements device-specific allocators and adds a low-latency allocator for both GPUs architectures. The previous review comments have been addressed, I hope, plus a lot of bugs have been found and fixed since the original post. With the addition of amdgcn I have broken out the heap implementation so both architectures can share the code.
