reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g.,
yann@935
     4
MPC8548, MPC8572).  It uses eglibc (for e500/SPE patches) and a recent
yann@2139
     5
gcc (4.5.1, for e500v2 DPFP support) and will generate appropriate

     6
dual-precision floating point instructions by default.

Note: If building a Linux kernel with this toolchain, you will want to

make sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE

    10
ABI/instructions from getting into the kernel (which is currently
yann@2139
    11
unsupported).  At this time, the kernel build system passes those
yann@2139
    12
teo options, but older kernels were only passing -mno-spe by default."
