Subject: [PATCH 02/12] mode-switching: Add note problem
Date: Sun, 05 Nov 2023 18:46:40 +0000 [thread overview]
Message-ID: <mptr0l482cv.fsf@arm.com> (raw)
In-Reply-To: <mpt34xk9gza.fsf@arm.com> (Richard Sandiford's message of "Sun, 05 Nov 2023 18:45:29 +0000")
optimize_mode_switching uses REG_DEAD notes to track register
liveness, but it failed to tell DF to calculate up-to-date notes.
Noticed by inspection. I don't have a testcase that fails
because of this.
gcc/
* mode-switching.cc (optimize_mode_switching): Call
df_note_add_problem.

I was tempted to apply this as obvious, but wasn't sure if I was
missing something.
