Subject: [PATCH][3/n] Fixup hybrid SLP detection in patterns
Date: Fri, 02 Jun 2017 13:10:00 -0000 [thread overview]
Message-ID: <alpine.LSU.2.20.1706021509370.5291@zhemvz.fhfr.qr> (raw)
This matches up the two different implementations.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.
Richard.

* tree-vect-slp.c (vect_detect_hybrid_slp_2): Match up
what we consider a relevant use stmt with vect_detect_hybrid_slp_stmts.
