From 0c19df487136c4368757dc865b13dcc9c897dfe4 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Sat, 23 Aug 2008 22:23:09 +0000 Subject: Switch the asmprinter (.ll) and all the stuff it requires over to use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. llvm-svn: 55263 --- llvm/lib/Analysis/LoopVR.cpp | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) (limited to 'llvm/lib/Analysis/LoopVR.cpp') diff --git a/llvm/lib/Analysis/LoopVR.cpp b/llvm/lib/Analysis/LoopVR.cpp index eb7524a9c2f..7f5de259caf 100644 --- a/llvm/lib/Analysis/LoopVR.cpp +++ b/llvm/lib/Analysis/LoopVR.cpp @@ -6,6 +6,10 @@ // License.
