[PATCH] D40007: [NewPassManager] Pass the -fdebug-pass-manager flag setting into the Analysis managers to match what we do in opt

[Craig Topper via Phabricator via cfe-commits]

craig.topper created this revision.

Currently the -fdebug-pass-manager flag for clang doesn't enable the debug logging in the analysis managers. This is different than what the switch does when passed to opt.
