From: Andrew Pinski <apin...@marvell.com>
When I fixed PR 102622, I accidently left behind a TYPE_PRECISION
check which I had there for checking before hand. This check
is not needed as the code will handle it correctly anyways.
Committed as obvious after a bootstrap/test on x86_64-linux-gnu.
PR tree-optimization/10352
gcc/ChangeLog:
* match.pd: Remove check of TYPE_PRECISION for
the a?0:pow2 case.
gcc/testsuite/ChangeLog:
* gcc.c-torture/execute/pr10352-1.c: New test.
