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