Subject: [Bug target/64505] New: Powerpc compiler generates insn not found for -m32 -mpowerpc64
Date: Mon, 05 Jan 2015 21:04:00 -0000	[thread overview]
Message-ID: <bug-64505-4@http.gcc.gnu.org/bugzilla/> (raw)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64505

            Bug ID: 64505
           Summary: Powerpc compiler generates insn not found for -m32
                    -mpowerpc64
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: meissner at gcc dot gnu.org
          Reporter: meissner at gcc dot gnu.org
              Host: powerpc64-unknown-linux-gnu
            Target: powerpc64-unknown-linux-gnu
             Build: powerpc64-unknown-linux-gnu

Created attachment 34384
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34384&action=edit
File that shows the problem

Compiling the attached file will generate an insn not found error message if it
is compiled with the following options: -std=c99 -fno-strict-aliasing -Wall
-m32 -mpowerpc64 foo.c -S -O2.

The problem is inside of rs6000_secondary_reload, there is code for 64-bit and
32-bit. The reload insn that is returned is looking for a 64-bit scratch
register, but the combination of switches -m32 -mpowerpc64 it should be
generating a 32-bit scratch register.
