From 64d6460a56119c2da726d7de426dc8ac33e7f8bc Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Thu, 1 May 2014 00:31:47 +0200 Subject: gallivm: fix 2 leaks in disassembly code don't leak the MCSubtargetInfo (not really big, was already fixed with llvm master) and TargetMachine (big). While this is only used for debugging the leak is large enough to get you into trouble in some cases. Tested with llvm 3.1 and master.
