[PATCH] D144981: [Driver] Allow to collect `-save-stats` data to a file specified in the environment variable.

[Volodymyr Sapsai via Phabricator via cfe-commits]

vsapsai added a comment.

Adding folks involved with LTO. The problem is that stats emitted during the first round of compilation are likely to be overwritten by stats emitted during [Thin]LTO itself. Not touching it now to preserve the existing behavior. But wanted to inform you about this shortcoming in case it is important for you to fix.

Original change adding `-save-stats` for LTO is D45531 <https://reviews.llvm.org/D45531>.
