File: lib/Transforms/Scalar/SROA.cpp
On: http://10.1.1.2/svn/llvm-project
For: llvm

Changed By: chandlerc
Comments: Now that mem2reg understands how to cope with a slightly wider set of
uses of an alloca, we can pre-compute promotability while analyzing an
alloca for splitting in SROA. That lets us short-circuit the common case
of a bunch of trivially promotable allocas. This cuts 20% to 30% off the
run time of SROA for typical frontend-generated IR sequneces I'm seeing.
It gets the new SROA to within 20% of ScalarRepl for such code. My
current benchmark for these numbers is PR15412, but it fits the general
pattern of IR emitted by Clang so it should be widely applicable.Properties:
