Subject[PATCH 0/7] x86: remove always-defined CONFIG_AS_* options
Date
arch/x86/Makefile tests instruction code by $(call as-instr, ...)

Some of them are very old.
For example, the check for CONFIG_AS_CFI dates back to 2006.

We raise GCC versions from time to time, and we clean old code away.
The same policy applied to binutils.

The current minimal supported version of binutils is 2.21

This is new enough to recognize the instruction in most of
as-instr calls.



Masahiro Yamada (7):
x86: remove unneeded defined(__ASSEMBLY__) check from asm/dwarf2.h
x86: remove always-defined CONFIG_AS_CFI
x86: remove always-defined CONFIG_AS_CFI_SIGNAL_FRAME
x86: remove always-defined CONFIG_AS_CFI_SECTIONS
x86: remove always-defined CONFIG_AS_SSSE3
x86: remove always-defined CONFIG_AS_AVX
x86: add comments about the binutils version to support code in
as-instr
