Subject: vc4: Make a new #define for making code conditional on the simulator.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=af3d7471943d54e692f2dd7448321a4f96e56ed2;p=mesa.git

vc4: Make a new #define for making code conditional on the simulator.

I'd like to compile as much of the device-specific code as possible
when building for simulator, and using if (using_simulator) instead of
ifdefs helps.
