Release 11 - Kernel Compile error message after Spectre/Meltdown changes.

[Suporte - KONTROL]

Hello Gentlemen,

Greetings.

 

I Can't compile the stable 11 Kernel anymore after the changes related to
Spectre/Meltdown.

Before it, I could compile it normally. I am not sure what I am missing. If
some patch, if some Clang update/patch.

 

When compiling, I am getting errors like this one:

**********************************************

/tmp/FreeBSD-src/sys/amd64/amd64/support.S:829:2: error: unknown directive

.altmacro

^

<instantiation>:1:13: error: invalid register name

handle_ibrs_%(ll):

            ^~

**********************************************

 

Here is my OS and clang details:

 

root at freebsd:~ # uname -a

FreeBSD FreeBSD 11.1-RELEASE-p9 FreeBSD 11.1-RELEASE-p9 #0 r321309: Fri Jul

root at freebsd:~ # clang -v

FreeBSD clang version 4.0.0 (tags/RELEASE_400/final 297347) (based on LLVM
4.0.0)

Target: x86_64-unknown-freebsd11.1

Thread model: posix

InstalledDir: /usr/bin

 

** *** **** *************

Is there any update or patch I have to apply before compile it?

 

Any help will be greatly appreciated!

Thanks Much!

 

Fabricio.
