Yaxun (Sam) Liu dc6a0b0ec7 [HIP] Align device binary ... To facilitate faster loading of device binaries and share them among processes, HIP runtime favors their alignment being 4096 bytes. HIP runtime can load unaligned device binaries, however, aligning them at 4096 bytes results in faster loading and less shared memory usage. This patch adds an option -bundle-align to clang-offload-bundler which allows bundles to be aligned at specified alignment. By default it is 1, which is NFC compared to existing format. This patch then aligns embedded fat binary and device binary inside fat binary at 4096 bytes. It has been verified this change does not cause significant overall file size increase for typical HIP applications (less than 1%).
