[powerpc] Rename fesetenv_mode to fesetenv_control
|
|
|
7c0489 |
|
|
|
7c0489 |
fesetenv_mode is used variously to write the FPSCR exception enable
|
|
|
7c0489 |
bits and rounding mode bits. These are referred to as the control
|
|
|
7c0489 |
bits in the POWER ISA. Change the name to be reflective of its
|
|
|
7c0489 |
current and expected use, and match up well with fegetenv_control.
