From 12c9413228d2955126ff5c45194f8aacf1aa81f6 Mon Sep 17 00:00:00 2001 From: Martin Liska Date: Tue, 13 Oct 2020 16:44:47 +0200 Subject: [PATCH] IPA: fix profile handling in IRA gcc/ChangeLog: PR ipa/97295 * profile-count.c (profile_count::to_frequency): Move part of gcc_assert to STATIC_ASSERT. * regs.h (REG_FREQ_FROM_BB): Do not use count.to_frequency for a function that does not have count_max initialized.
