Subject: [PATCH] gdb: do not add const sections to the section map
Date: Mon, 16 May 2022 21:42:09 +0200 [thread overview]
Message-ID: <20220516194209.2470009-1-iii@linux.ibm.com> (raw)
From: Ulrich Weigand <ulrich.weigand@de.ibm.com>
build_objfile_section_table () creates four synthetic sections, which
significantly slow down section map sorting. This is especially
noticeable when debugging JITs that report a lot of objfiles. Since
these sections are not useful for find_pc_section (), do not add them
to the section map.
