[PATCH 16/35] target/ppc: Tidy inexact handling in do_fri


From: Richard Henderson
Subject: [PATCH 16/35] target/ppc: Tidy inexact handling in do_fri
Date: Fri, 19 Nov 2021 17:04:43 +0100

In GEN_FLOAT_B, we called helper_reset_fpstatus immediately
before calling helper_fri*.  Therefore get_float_exception_flags
is known to be zero, and this code can be simplified.
