From 430797843a4e9b3bc69562c4ef18dd2ddda39990 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 11 May 2016 04:42:51 +0200 Subject: [PATCH] gallivm: improve dumping of bitcode Use GALLIVM_DEBUG=dumpbc for dumping of modules as bitcode. Instead of a fixed llvmpipe.bc name, use ir_.bc so multiple modules can be dumped (albeit it might still overwrite previous modules, particularly the modules from draw tend to always have the same name).
