From 7f2b87189bea763f1edb7f63e8cf8f2e1ed2d502 Mon Sep 17 00:00:00 2001 From: Will Schmidt Date: Wed, 19 May 2021 20:11:57 -0500 Subject: [PATCH] [PATCH]rs6000,testsuite Add a powerpc64-prologue testcase. Add a powerpc64-prologue testcase, this is based on the existing powerpc-prologue test, but updated for the powerpc64 (le) target.
