Hi Eric,
using your nice patch, I expected both a speed increase and a size
decrease. The latter did not happen, because the exception is
tested twice.
#define StacklessUnwindAndRPyExceptionHandling(unwind_label,
resume_label, exception_label) \
if (RPyExceptionOccurred()) { \
if (slp_frame_stack_bottom) \
goto unwind_label; \
resume_label: \
if (RPyExceptionOccurred()) \
FAIL(exception_label); \
}
Just out of curiosity: does the code shrink if we do this? :
#define StacklessUnwindAndRPyExceptionHandling(unwind_label,
resume_label, exception_label) \
resume_label: \
if (RPyExceptionOccurred()) { \
if (slp_frame_stack_bottom) \
goto unwind_label; \
FAIL(exception_label); \
}
Maybe this is slightly less machine code and not slower in the
common case. Is it correct, btw? :-)
ciao - chris
