48/* The e500 ABI says that either long doubles are 128 bits, or if
49   implemented in any other size, the compiler/linker should error out.
50   We have no emulation libraries for 128 bit long doubles, and I hate
51   the dozens of failures on the regression suite.  So I'm breaking ABI
52   specifications, until I properly fix the emulation.
