[Mesa-dev] [PATCH v5] intel: aubinator: generate a standalone binary
Lionel Landwerlin

Fri Oct 7 09:27:14 UTC 2016
Embed the xml files into the binary, so aubinator can be used from any
location.
v2: Split generation packing into another patch (Jason)
Check for xxd (Jason)
v3: Fix out of tree builds (Jason)
Generate custom variable name rather than names generated by xxd
(Lionel)
v4: Move generated _xml.h files to genxml/ (Sirisha)
v5: Remove newline from makefile (Jason)
