Subject: [PATCH 02/12] ipa-cp: Do not consider useless aggregate constants
Date: Sat, 12 Nov 2022 02:45:28 +0100 [thread overview]
Message-ID: <ri6tu35kksn.fsf@suse.cz> (raw)
Hi,
When building vectors of known aggregate values, there is no point in
including those for parameters which are not used in any way
whatsoever.
Bootstrapped and tested on x86_64-linux. OK for master?
Thanks,
Martin
gcc/ChangeLog:
2022-11-11 Martin Jambor <mjambor@suse.cz>
* ipa-cp.cc (push_agg_values_from_edge): Do not consider constants
in unused aggregate parameters.
