Hi,
I ran into a problem while porting OpenOffice 625 to ppc linux. To turn off
exceptions under linux they set the fpu_control word to _FPU_IEEE. This
works under x86 linux.
Under ppc linux, in fpu_control.h _FPU_IEEE sets the control word to
0x000000F0 which actually enables overflow, underflow, divide by zero,
and invalid fpu exceptions. _FPU_DEFAULT actually disables them.
Isn't fpu_control.h supplied by glibc?
If so, shouldn't _FPU_IEEE be actually disabling fpu exceptions under ppc
linux and not enabling them?
Is this an issue in current glibc CVS too?
Thanks,
Kevin
