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