Subject: mesa: move _mesa_half_is_negative() to half_float.h
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c43b0d3f9184752e848ef0ab617cca48c60246ec;p=mesa.git

mesa: move _mesa_half_is_negative() to half_float.h

v2: use !! in the function to be explicit about type conversion.  Though,
gcc generates the same code with or without the logical !!.
