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