[llvm-commits] [llvm] r169747 - /llvm/trunk/lib/MC/MCAssembler.cpp

New Revision: 169747

URL: http://llvm.org/viewvc/llvm-project?rev=169747&view=rev
Log:
This patch adds statistics for other non-DWARF fragments emitted by
the assembler. This is useful in order to know how the numbers add up,
since in particular the Align fragments account for a non-trivial
portion of the emitted fragments (especially on -O0 which sets
relax-all).
