Author: Mans Rullgard <[email protected]> Committer: Mans Rullgard <[email protected]> Date: Sun Oct 2 23:38:32 2011 +0100 ARM: check for inline asm 'y' operand modifier support The inline asm added in bf5d46d uses the 'y' modifier which is only supported from gcc 4.5. This check allows building with older compilers.
