catastrophic error: unknown register name %1 in asm statement

I got an error :

../kernel/x86_64/cscal_microk_haswell-2.c(233): catastrophic error: unknown register name %1 in asm statement

compilation aborted for ../kernel/x86_64/cscal.c (code 4)

Which linux, which compiler? Compiler flags?

Could be that your version of binutils (assembler and related files) is too old

[akakcolin]

The linux system is Centos

Distributor ID: CentOS
Description: CentOS Linux release 7.1.1503 (Core)
Release: 7.1.1503
Codename: Core
Linux hsw-01 3.10.0-229.20.1.el7.x86_64

The Package binutils-2.23.52.0.1-55.el7.x86_64 is already installed and is the latest version

Using gcc/gfortran can build successully.
Using icc/ifort cannot build with the same error

using "make BINARY=64 CC=icc FC=ifort"

Hmm. #493 was solved by updating to binutils 2.25 ? (The error message there was different -
but the only reference to your "unknown register name %" I can find was relevant for an icc version from ten years ago that did not yet recognize the gcc-style register naming.).
If you are sharing the same source tree between different machines or different compilers, be sure to do a "make clean" before the "make"

@akakcolin ， could you try gcc? make CC=gcc FC=ifort
