Following up on my previous experiment, I tried the same input with the xgcc
which is failing to build libdecnumber. If also fails with the 1-line test

sldi and srdi are both standard PowerPC64 instructions.
How did you configure GCC?

One of target platforms is running RHEL 6.2 on a POWER7 series processor.
The binutils RPM is:
