Subject: freedreno/a6xx: fix hangs with large shaders
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=04c2520d91920725d91a7be6e415d6ab56aeeaab;p=mesa.git

freedreno/a6xx: fix hangs with large shaders

We were overflowing instrlen (which is # of groups of 16 instructions)
in a couple dEQP tests, causing gpu hangs:

dEQP-GLES31.functional.ubo.random.all_per_block_buffers.13
dEQP-GLES31.functional.ubo.random.all_per_block_buffers.20
