Bug #: 53512
Summary: SH Target: Allow fsca and fsrra for non-SH4A
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: olegendo@gcc.gnu.org
CC: kkojima@gcc.gnu.org
Target: sh4*-*-*
Currently the fsca and fsrra insns are available only for SH4A. However, there
are some SH4 variants around (e.g. SH7091) that also support those insns.
My idea was to add the following options:
-mfsca, -mno-fsca
-mfsrra, -mno-fsrra
...to be able to manually enable/disable the respective insns. On SH4A -mfsca
and -mfsrra would be enabled by default when setting
-funsafe-math-optimizations, which would preserve the current behavior.
Any objections?
