https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236313 --- Comment #4 from commit-hook@freebsd.org --- A commit references this bug: Author: dim Date: Mon Mar 11 19:15:57 UTC 2019 New revision: 345021 URL: https://svnweb.freebsd.org/changeset/base/345021 Log: Pull in r355854 from upstream llvm trunk (by Jonas Paulsson): [RegAlloc] Avoid compile time regression with multiple copy hints. As a fix for https://bugs.llvm.org/show_bug.cgi?id=3D40986 ("excessive compile time building opencollada"), this patch makes sure that no phys reg is hinted more than once from getRegAllocationHints(). This handles the case were many virtual registers are assigned to the same physreg. The previous compile time fix (r343686) in weightCalcHelper() only made sure that physical/virtual registers are passed no more than once to addRegAllocationHint(). Review: Dimitry Andric, Quentin Colombet https://reviews.llvm.org/D59201 This should fix a hang when compiling certain generated .cpp files in the graphics/opencollada port.
