Subject: [PATCH][ARM][GCC][3/x]: MVE ACLE intrinsics framework patch.
Date: Thu, 14 Nov 2019 19:13:00 -0000 [thread overview]

Hello,
This patch is part of MVE ACLE intrinsics framework.
The patch supports the use of emulation for the double-precision arithmetic
operations for MVE. This changes are to support the MVE ACLE intrinsics which
operates on vector floating point arithmetic operations.
Please refer to Arm reference manual [1] for more details.
[1] https://static.docs.arm.com/ddi0553/bh/DDI0553B_h_armv8m_arm.pdf?_ga=2.102521798.659307368.1572453718-1501600630.1548848914
Regression tested on arm-none-eabi and found no regressions.
Ok for trunk?
Thanks,
Srinath.
