Roland,

c1_LIRAssembler_sparc.cpp: consider using not short branch instruction because the distance could be big (stop() generates a lot of code):

3135 __ ba_short(next);

Otherwise it seems good.

Thanks, Vladimir

The main difference with the x86 code is that on sparc, the current profile value is loaded, checked & updated and finally stored rather than checked & updated in place as is done on x86. As a consequence the code is somewhat simpler because concurrent updates to the profile are not possible. Roland.
