Hi,
I have a question about a libcall.
Let's say a libcall returns its result in (reg 0). Is it normal to
have multiple references to (reg 0) after the libcall? Or are we
supposed to copy (reg 0) to some pseudo reg and then use that pseudo
reg as many times as needed?
Any information to this helps me diagnose a testsuite failure.
Thanks,
Kazu Hirata
