Subject: [PATCH 25/42] PowerPC: modf optimization
|
||||
|
||||
This patch implements modf/modff optimization for POWER by focus
|
||||
on FP operations instead of relying in integer ones.
|
||||
(backported from commit 3c0265394d9ffedff2b0de508602dc52e077ce5c)
|
||||
|
||||
This backport does not include the benchmark tests from the original
|
||||
commit.

Subject: [PATCH 26/42] PowerPC: modf optimization fix
|
||||
|
||||
This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits
|
||||
by correctly setting minimum architecture for modf PPC optimization
|
||||
to power5+ instead of power5 (since only on power5+ round/ceil will
|
||||
be inline to inline assembly).
|
||||
(cherry picked from commit aa630f590c9c7d070a7cdf3a2a88069ad6b63de9)
