Bug ID: 193768
Summary: src.conf/make.conf: CFLAGS/COPTFLAGS inconsistency
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
man make.conf states, that COPTFLAGS is used for building/compiling the kernel
(exclusively). The question arises: are kernel modules NOT kernel or are they
kernel?
The problem I face is that with optimization level -O3 loader.efi gets
miscompiled and a
UEFI laptop stops/reject booting. To avoid other interference, I defined
COPTFLAGS
in /etc/src.conf accordingly, but leave CFLAGS?=-O3 in /etc/make.conf for
compilation of
regular ports and the rest of the OS.
I can observe that with CFLAGS set, either in make.conf, or src.conf or mutual
exclusive,
the CFLAGS is ALWAYS incorporated when kernel stuff like modules and even the
loader.efi
is built! I consider this inconsitent, since loader.efi is definitely kernel
related
stuff as well as modules.
