Subject: Enable DSPr2 SIMD extensions if CPU type is mipsel
X-Git-Tag: 2.0.1~12
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4f943644e5bf7544f126ce1d23e430e649a82c41;p=libjpeg-turbo

Enable DSPr2 SIMD extensions if CPU type is mipsel

The DSPr2 extensions have been verified to work with little endian MIPS.
Whether or not CMAKE_SYSTEM_PROCESSOR is set to "mips" or "mipsel" in a
little endian MIPS environment seems to be inconsistent, but our build
system needs to handle both cases.
