Thanks, I'll forward the patches to quipper team.

That's correct. For trunk, gcov_version is 0x1. We defined this as a
flag so that you can actually change it via --gcov_version=0x1 instead
of changing the code.

did a batch sync with quipper head. Please let me know if this
solves the perf problem.

In that case, we should get quipper fixed upstream to accommodate new
format. (Maybe they already fixed it, I will do a batch sync to make
quipper up-to-date).

I'll get to it soon. When will stage1 close?
OTOH, the most important patch (insn-level discriminator support) is
not in yet. Cary has just retired. Do you know if anyone would be
interested in porting insn-level discriminator support to trunk?

We have open-sourced AutoFDO profile toolchain in:

For GCC developers, the most important tool is create_gcov, which
converts sampling based profile to GCC-readable profile. Please refer

Hi,
In tree-vect-loop.c, it limits the vectorization only to loops that have 2 BBs:
/* Inner-most loop. We currently require that the number of BBs is
exactly 2 (the header and latch). Vectorizable inner-most loops
look like this:
(pre-header)
Yes, this is a known problem: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54645
A patch was proposed: http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01563.html
Sorry to break the test.
