Subject: radeon/llvm: Specify the DataLayout when running optimizations
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6f3465f340b5e2b1419330f2c1fcb61fbe087af7;p=mesa.git

radeon/llvm: Specify the DataLayout when running optimizations

Without DataLayout, a lot of optimization passes aren't run and the ones
that are don't work as well.
