[Mesa-dev] [PATCH 01/11] glsl: Refactor code to find NIR opcode for an intrinsic and add unit test

Ian Romanick idr at freedesktop.org
Wed Jul 6 00:46:09 UTC 2016


From: Ian Romanick <ian.d.romanick at intel.com>

The next patches are going to significantly change the implementation,
so I really want a unit test.

   text	   data	    bss	    dec	    hex	filename
7529123	 273096	  28584	7830803	 777d13	/tmp/i965_dri-64bit-before.so
7529283	 273096	  28584	7830963	 777db3	/tmp/i965_dri-64bit-after.so

I'm honestly not sure why it grew by 160 bytes.
