Subject: target/ppc: Check endianness at runtime in ppc_data_endian_env()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ef4fee1a6a832b4917cb9ae8e22866534e11342;p=thirdparty%2Fqemu.git

target/ppc: Check endianness at runtime in ppc_data_endian_env()

Rather a runtime endianness check via env MSR over
a build-time one.

Now CPU can change endianness at runtime.
