Subject: [PATCH] lto/109263 - lto-wrapper and -g0 -ggdb
Date: Thu, 23 Mar 2023 17:00:29 +0100 (CET) [thread overview]
Message-ID: <20230323160030.02D4813596@imap2.suse-dmz.suse.de> (raw)
The following makes lto-wrapper deal with non-combined debug
disabling / enabling option combinations properly. Interestingly
-gno-dwarf also enables debug.
Bootstrap / regtest running on x86_64-unknown-linux-gnu.
OK? Or do we want to try harder to zap earlier -g0 when later
-g* appear?
PR lto/109263
* lto-wrapper.c (run_gcc): Parse alternate debug options
as well, they always enable debug.
