Subject: various: Fix missing DumpModule with recent LLVM.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fca80b3db64dc1d004f78e22b9de86a07e9de96;p=mesa.git

various: Fix missing DumpModule with recent LLVM.

Since LLVM revision 293359 DumpModule gets only implemented when
either a debug build or LLVM_ENABLE_DUMP is set.

This patch adds a direct replacement for the function for radv and
radeonsi, However, as I don't know a good place to put common LLVM
code for all three I inlined the implementation for LLVMPipe.

v2: Use the new code for LLVM 3.4+ instead of LLVM 5+ & fixed indentation
