Bug #: 52775
Summary: Change default for using FCFID instruction
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: meissner@gcc.gnu.org
ReportedBy: meissner@gcc.gnu.org
Host: powerpc64-linux power-linux
Target: powerpc64-linux
Build: powerpc64-linux
Back in August 2010, when I updated the floating point conversion support for
powerpc, I made the default for using the FCFID instruction to be any of: -m64,
-mpopcntb (power5), -mcmpb (power6), -mpopcntd (power7), -mvsx. Evidently any
powerpc that can support 64-bit (even if the current target is 32-bit) has the
FCFID instruction. So I would like to modify the trunk and active branches to
enable FCFID in 32-bit mode on power4.
