Comment 1 Peter Robinson 2021-03-24 14:41:45 UTC

Is this with LTO enabled?

Comment 2 Dan Horák 2021-03-24 14:53:46 UTC

I suspect it's the same issue we see in our CI on all other platforms as well. After an update to the swgl component by FF upstream it requires an excessive amount of memory (and time too) for the rust -> g++ -> gas process tree (on ppc64le cc1plus tops at 8GB, gas needs additional 5GB).

Comment 3 Martin Stransky 2021-03-24 14:57:44 UTC

> Is this with LTO enabled?

We build with PGO+LTO on Intel only.

Comment 4 Dan Horák 2021-04-02 07:52:52 UTC

I don't have a proof, but it looks to me that the excessive amount of memory isn't required for builds of trunk any more.
