[PULL 07/28] target/alpha: Tidy helper_fp_exc_raise_s


From: Alex Bennée
Subject: [PULL 07/28] target/alpha: Tidy helper_fp_exc_raise_s
Date: Thu, 26 Sep 2019 19:35:32 +0100

From: Richard Henderson <address@hidden>

Remove a redundant masking of ignore.  Once that's gone it is
obvious that the system-mode inner test is redundant with the
outer test.  Move the fpcr_exc_enable masking up and tidy.

No functional change.
