From 7d2c27a0ec5ecec980b623ded45758918c00b164 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Sat, 7 Jun 2025 10:52:28 +0200 Subject: bug: Add report_bug_entry() Add a report_bug() variant where the bug_entry is already known. This is useful when the exception instruction is not instantiated per-site. But instead has a single instance. In such a case the bug_entry address might be passed along in a known register or something.
