r242200 - in /branches/ARM/sve-branch/gcc: tree...


Author: rsandifo

New Revision: 242200

Log:
Add a vect_worthwhile_without_simd_p helper routine

For some operations we'll consider lowering "vector" operations
into N scalar word operations.  This N needs to be fixed at
compile time, so the condition guarding it needs to change
when variable-lengh vectors are added.  This patch puts the
condition into a helper routine so that there's only one
place to update.
