            Bug ID: 61827
           Summary: gcc.target/i386/fuse-caller-save-xmm.c FAILs
           Product: gcc
           Version: 4.10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

              Host: i386-pc-solaris2.11, x86_64-unknown-linux-gnu
            Target: i386-pc-solaris2.11, x86_64-unknown-linux-gnu
             Build: i386-pc-solaris2.11, x86_64-unknown-linux-gnu

The new gcc.target/i386/fuse-caller-save-xmm.c testcase FAILs in various
different ways on different targets:

* On Solaris 11/x86 with Sun as, there can be no cfi directives since that
  assembler doesn't fully support them yet:

FAIL: gcc.target/i386/fuse-caller-save-xmm.c scan-assembler-times
.cfi_def_cfa_offset 16 1
FAIL: gcc.target/i386/fuse-caller-save-xmm.c scan-assembler-times
.cfi_def_cfa_offset 32 1

  for both 32 and 64-bit.

* On Solaris 11/x86 with gas, I see the same failures although cfi directives
  are used.

* On Linux/x86_64, I see
FAIL: gcc.target/i386/fuse-caller-save-xmm.c scan-assembler-times
.cfi_def_cfa_offset 32 1

  for 32-bit only.  In the 32-bit .s file, I find

        .cfi_def_cfa_offset 16
        .cfi_def_cfa_offset 4

  compared to 64-bit

        .cfi_def_cfa_offset 16
        .cfi_def_cfa_offset 8
        .cfi_def_cfa_offset 32
        .cfi_def_cfa_offset 8
