From 866793109e471a5ed6cf2aa3ef519d830a184e11 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Tue, 25 Jun 2013 13:34:40 +0000 Subject: BlockFrequency: Bump up the entry frequency a bit. This is a band-aid to fix the most severe regressions we're seeing from basing spill decisions on block frequencies, until we have a better solution. llvm-svn: 184835 --- llvm/lib/Analysis/BlockFrequencyInfo.cpp | 5 ----- llvm/lib/CodeGen/MachineBlockFrequencyInfo.cpp | 5 ----- 2 files changed, 10 deletions(-) (limited to 'llvm/lib') diff --git a/llvm/lib/Analysis/BlockFrequencyInfo.cpp b/llvm/lib/Analysis/BlockFrequencyInfo.cpp index 100e5c8ae7d..8469556f64c 100644 --- a/llvm/lib/Analysis/BlockFrequencyInfo.cpp +++ b/llvm/lib/Analysis/BlockFrequencyInfo.cpp @@ -53,11 +53,6 @@ void BlockFrequencyInfo::print(raw_ostream &O, const Module *) const { if (BFI) BFI->print(O); } -/// getblockFreq - Return block frequency.
