From: Jason Ekstrand Date: Mon, 18 Apr 2016 21:25:03 +0000 (-0700) Subject: anv: Add a new block-based batch emit macro X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=64ad2d3bcd9bcbb49ef3840446f560e0f11a1f70;p=mesa.git anv: Add a new block-based batch emit macro This new macro uses a for loop to create an actual code block in which to place the macro setup code. One advantage of this is that you syntatically use braces instead of parentheses. Another is that the code in the block doesn't even get executed if anv_batch_emit_dwords fails.
