unigine-heaven full output (nothing special)

Problem is when i set high or above settings. It stops work, just after the loading process with message:
LLVM ERROR: Not supported instr: <MCInst 2210 <MCOperand Reg:3171> <MCOperand Imm:24> <MCOperand Reg:2044> <MCOperand Reg:74>>

llvm-r227384 - is good one.
llvm-r227463 - is bad one

If you need i can bisect this, but not now. 

Low or medium quality works good.

Run as MESA_GL_VERSION_OVERRIDE=4.0 MESA_GLSL_VERSION_OVERRIDE=400 ./heaven and and you will see that at high settings required shader5

Unigine Heaven GL_ARB_gpu_shader5
Comment 3 commiethebeastie 2015-01-30 22:12:21 UTC 
Oh sorry It`s was my mistake. UH4 does not require shaders 5.
Comment 4 Arek Ruśniak 2015-01-30 23:29:14 UTC 
Maybe it wasn't clearly enough, it looks like llvm regression.

Radeonsi doesn't even support shader5. 

Could you try if UH4 works for you with high/ultra(without override GL4)? And what revision of llvm do you use?
Comment 5 Arek Ruśniak 2015-02-01 08:29:25 UTC 
Ok, problem is fixed. Everything works good ok by now. 
Thx Tom
