Bezüglich O. Hartmann's Nachricht vom 23.09.2014 14:16 (localtime):
Modules and kernel are built when running make buildkernel, but the other
contents
of /boot/ aren't. How can I manually - and separately - build the loader,
especially /boot/loader.efi?
Simply cd to src/sys/boot and do 'make clean make make
DESTDIR=/altroot', the latter only if you don't want to overwrite
curdev's /boot/ files.
For loader.efi only, it's enough to do 'make clean make' in the
following directories:
src/sys/boot/ficl
src/sys/boot/efi
src/sys/boot/amd64/efi
From amd64/efi you can 'make install' to just copy loader.efi (or copy
manually from obj/$src/sys/boot/amd64/efi/loader.efi)
I realized that building loader.efi with any kind of optimization beyond
debugging- or
close-to-debugging level ends up in an unloadable loader.efi on Haswell CPUs
(IvyBridge
and C2D seem to be unaffected). The system in question is the most recent
CURRENT,
compiled with system's CLANG 3.4.1.
This is confirmed for CPUTYPE=core-avx2, see my recent post. My test
machine was haswell as well, but I haven't tested on anything else!
