strip-flags: CFLAGS: changed '-march=native -fgraphite-identity -floop-nest-optimize -fuse-linker-plugin -pipe -fomit-frame-pointer -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu' to '-march=native -pipe -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu'

It's probably the -Wl, flags. Since you are using lld, I have no idea what those flags will do.

owenthewizard commented 6 years ago

Hmm, same error even after stripping away the -Wl flags...

InBetweenNames commented 6 years ago

I doubt this is an LTO/-O3/Graphite/-fipa-pta issue then. Curiously, strip-flags does not acknowledge your -O setting.

InBetweenNames commented 6 years ago

Going to close this as it does not appear to be an lto-overlay related issue.
