From 2c00542c70b9cbd6da510c97cd3d46adcf9e3efc Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Mon, 14 Jan 2019 13:12:35 +0100 Subject: [PATCH] include/fpu/softfloat: Fix compilation with Clang on s390x MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Clang v7.0.1 does not like the __int128 variable type for inline assembly on s390x: In file included from fpu/softfloat.c:97: include/fpu/softfloat-macros.h:647:9: error: inline asm error: This value type register class is not natively supported! asm("dlgr %0, %1" : "+r"(n) : "r"(d)); ^ Disable this code part there now when compiling with Clang, so that the generic code gets used instead.
