This function just returns some global variable,

Hi all,
These tests use very large arrays as part of their loop interchange

Hi all,
I noticed that we use UNSPEC_CLS for the clrsb optab when we could be using the
RTL code for it. I don't see any reason not to use the RTL code and some
execution tests confirm that the cls instruction implements the expected clrsb
semantics. This patch removes the UNSPEC_CLS
Hi all,
Following up on patch [1/2] Remove UNSPEC_CLS and use clrsb RTL code in its'

The CLZ and CLRSB cases are handled identically (they are implemented by the

In looking at David's gcov patch I noticed that other changes have introduced
more global symbols into the user's namespace, without even using a gcov prefix.
That's bad. This patch gets rid of one of them (set_gcov_list).
