commit 6623c02d70c3732dbea59c6d79c69501baf9627b
Author: Zahira Ammarguellat <zahira.ammarguellat@intel.com>
Date: Wed Nov 17 11:53:36 2021 -0500
The _Float16 type is supported on x86 systems with SSE2 enabled.
Operations are emulated by software emulation and “float” instructions.
This patch is allowing the support of _Float16 type without the use of
-max512fp16 flag. The final goal being, perform _Float16 emulation for
all arithmetic expressions.
