[Patch][binutils][arm] .bfloat16 directive for Arm [6/X]
Hi,
This patch is part of a series that adds support for Armv8.6-A
(Matrix Multiply and BFloat16 extensions) to binutils.
This patch implements the '.bfloat16' directive for the Arm backend.
The syntax for the directive is:
.bfloat16 <0-n numbers>
e.g.
.bfloat16 12.0
.bfloat16 0.123, 1.0, NaN, 5
This is implemented by utilizing the ieee_atof_detail function (included
in the previous patch) in order to encode the slightly different
bfloat16 format.
Added testcases to verify the correct encoding for various bfloat16
values (NaN, Infinity (+ & -), normals, subnormals etc...).
Cross compiled and tested on arm-none-eabi and arm-none-linux-gnueabihf
with no issues.
Committed on behalf of Mihail Ionescu.

Is it ok for trunk?
