Unimplemented operand for __builtin_return_address and __builtin_frame_address(0) #41

Closed tkoenig1 closed 1 year ago

tkoenig1 commented 1 year ago

Reduced from the gcc testsuite.

The following functions hit an "unimplemented operand" message:

void test4() { volatile long a = (long)__builtin_return_address(0); }

and

void test4() { volatile long a = (long)__builtin_frame_address(0); }

I'm not sure that these even make sense on My 66000, it may be enough to just error out on an unimplemented builtin function.

Try commit ccd5046eb072.

No ICE, and the assembly looks reasonable.

Thanks!
