[PATCH 03/21] etnaviv: compiler: extract compile shader from tgsi

[Philipp Zabel]

From: Michael Tretter <m.tretter at pengutronix.de>

Prepare for compilation from NIR. etna_compile_shader will call either
etna_compile_shader_tgsi or etna_compile_shader_nir, depending on
whether the input is TGSI or NIR.
