Subject: radeon/llvm: Don't use the global context when parsing LLVM IR
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7cc98ea88f5ec24369ba8123007637e47f093726;p=mesa.git

radeon/llvm: Don't use the global context when parsing LLVM IR

This leads to crashes when multiple threads try to compile compute
shaders in the same time.

Fixes a crash in bfgminer when using more than one thread.
