-Subject: [PATCH] rtl-optimization/119689 - compare-debug failure with LRA
-
-The previous change to fix LRA rematerialization broke compare-debug
-for i586 bootstrap.  Fixed by using prev_nonnote_nondebug_insn
-instead of prev_nonnote_insn.
-
-Bootstrapped on i586-linux where the miscompare is gone with this
-patch.  Bootstrap and regtest running on x86_64-unknown-linux-gnu.
-
-OK if the latter succeeds?
-
-Thanks,
-Richard.
-
-	PR rtl-optimization/119689
-	PR rtl-optimization/115568
-	* lra-remat.cc (create_cands): Use prev_nonnote_nondebug_insn
-	to check whether insn2 is directly before insn.
-
-* g++.target/i386/pr119689.C: New testcase.
