Subject: anv: don't pass xmlfile via stdin anv_entrypoints_gen.py
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1610b3dede1d0d3246bd803f80ec5f2843668cda;p=mesa.git

anv: don't pass xmlfile via stdin anv_entrypoints_gen.py

It's slow, and has the potential for encoding issues.

v2: - pass xml file location via argument
    - update Android.mk
