          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

The test file.

The cross-compiler gcc-4.7.4:

Configured with: /home/niva/src/gcc-4.7.4/configure --target=mips64-none-elf
--enable-threads=no --disable-shared --enable-long-long --enable-c99
--enable-languages=c --enable-multilib --enable-symvers=gnu
--disable-libmudflap --disable-libssp --disable-libgcc_eh --with-newlib
--with-dwarf2 --with-system-zlib --enable-generated-files-in-srcdir --verbose
--prefix=/home/niva/local --enable-cpp

    The command line is:

mips64-none-elf-gcc-4.7.4 prfl.c -O3 -G0 -mips64 -mpaired-single -mabi=o64 -S

    The error message:

prfl.c:42:1: error: unable to find a register to spill in class âGR_REGSâ
prfl.c:42:1: error: this is the insn:
(insn 79 65 117 2 (set (reg:CCV2 360)
        (unspec:CCV2 [
                (unlt (reg:V2SF 34 $f2 [orig:306 MEM[(float[4] *)&s1 + 8B] ]
[306])
                    (reg:V2SF 33 $f1 [orig:307 MEM[(float[4] *)&s2 + 8B] ]
[307]))
            ] UNSPEC_SCC)) prfl.c:15 701 {sunlt_ps}
     (nil))
prfl.c:42: confused by earlier errors, bailing out

The source file is attached. It was produced from 
gcc-4.7.4/gcc/testsuite/gcc.c-torture/execute/ieee/pr50310.c 
as a result of substitution of the "float" type instead of "double".
