Subject: radeonsi: add always-inline pass to si_llvm_finalize_module
X-Git-Tag: upstream/17.1.0~5029
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=23dfb688ba3b7be0feb2a178e65e419fe2678379;p=platform%2Fupstream%2Fmesa.git

radeonsi: add always-inline pass to si_llvm_finalize_module

Change the pass manager as well, since this is a module-level pass. No
noticeable run-time difference on shader-db.
