sysv.S: Load correct cr to compare if we have long double.
2007-11-17 Andreas Tobler <a.tobler@schweiz.org>
* src/powerpc/sysv.S: Load correct cr to compare if we have long double.
* src/powerpc/linux64.S: Likewise.
* src/powerpc/ffi.c: Add a comment to show which part goes into cr6.
* testsuite/libffi.call/return_ldl.c: New test.
