-Subject: [Patch] pr65779 - [5/6 Regression] undefined local symbol on powerpc
-
-This patch removes bogus debug info left around by shrink-wrapping,
-which on some powerpc targets with just the right register allocation
-led to assembly errors.
-
-Bootstrapped and regression tested powerpc64-linux and x86_64-linux.

-	PR debug/65779
-	* shrink-wrap.c (insn_uses_reg): New function.
-	(move_insn_for_shrink_wrap): Remove debug insns using regs set
-	by the moved insn.
-gcc/testsuite/
-	* gcc.dg/pr65779.c: New.

-Upstream-Status: Pending (from mailing list, not merged yet)
