[LLVMdev] pb05 results for current llvm/dragonegg

[Jack Howarth]

  Attached are the Polyhedron 2005 benchmark results for current llvm/dragonegg svn
on x86_64-apple-darwin11 built against Xcode 4.3.2 and FSF gcc 4.6.3. The benchmarks
for -msse3 and -msse4 appear identical (at least for degg+optnz). This is fortunate
since there seems to be a bug in -msse4 on 2.33 GHz (T7600) Intel Core 2 Duo Merom
(http://llvm.org/bugs/show_bug.cgi?id=12434).
