From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Prakash Surya Date: Fri, 15 Sep 2017 11:47:11 -0700 Subject: [PATCH] Make "-fno-inline" compile option more accessible MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When functions are inlined, it can make the system much more difficult to instrument using tools such as ftrace, BPF, crash, etc. Thus, to aid development and increase the system's observability, when the "--enable-debuginfo" flag is specified, the "-fno-inline" compilation option will be used for both userspace and kernel modules.
