Bootstrapping with i386 and Microblaze target works fine. No

the gain of 9.3% is seen in rgbcmy_lite the EEMBC benchmarks.

What do you mean by there are "lesser failures"?  Are you saying there are cases where path splitting generates incorrect code, or cases where path >>splitting produces code that is less efficient, or something else?


I meant there are more Deja GNU testcases passes with the path splitting changes.

Ah, in that case, that's definitely good news!
