Hello,
This patch adds the feature macro __ARM_FEATURE_QRDMX to indicate the
presence of the ARMv8.1 instructions vqrdmlah and vqrdmlsh. It is
defined when the instructions are available, as it is when
-march=armv8.1-a is enabled with suitable fpu options.
Tested the series for arm-none-eabi with cross-compiled check-gcc on an
ARMv8.1 emulator. Also tested arm-none-linux-gnueabihf with native
bootstrap and make check.
Ok for trunk?
