[PATCH] D24826: [LTO] Add -flto-jobs=N to control backend parallelism

[Mehdi AMINI via cfe-commits]

mehdi_amini added a comment.

Also I don't think the same option should be used for the parallel LTO codegen: it actually does not generate the same binary, which should deserve a dedicated opt-in (What if I mix ThinLTO and LTO, and I don't want // codegen?)
