Hi,
As commented at https://gcc.gnu.org/ml/gcc-patches/2014-09/msg00684.html,
this is a simple patch enabling neon memset inlining on
cortex-a53/cortex-a57 in AArch32 mode.
Test on
arm-none-linux-gnueabihf/--with-cpu=cortex-a57/--with-fpu=crypto-neon-fp-arm
v8/--with-float=hard. I will further collect benchmark data, see if there
is regression.
Is it ok if benchmark results are good?
