From 5e8ebd841a44b895e2bab5e874ff7d333ca31135 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Thu, 26 Mar 2020 17:00:58 +0900 Subject: x86: probe assembler capabilities via kconfig instead of makefile Doing this probing inside of the Makefiles means we have a maze of ifdefs inside the source code and child Makefiles that need to make proper decisions on this too. Instead, we do it at Kconfig time, like many other compiler and assembler options, which allows us to set up the dependencies normally for full compilation units. In the process, the ADX test changes to use %eax instead of %r10 so that it's valid in both 32-bit and 64-bit mode. Signed-off-by: Jason A.
