ygao added you to the CC list for the revision "Adding type info for f16c
floating-point type".
Hi,
The following patch adds support for half-precision floating point type
supported by the clang front-end.
Native operations on this type is supported by OpenCL and to a limited extent
by f16c (conversions are
supported); otherwise it is a storage-only type.
Could someone take a look whether this is good to go in?
- Gao.
