Dear all: there's no sun studio mailling list in opensolaris.org, i raise my problem here :)
a simple piece of code, 2 nested while loops, and some if statements inside each while loop. i compiled this program in Solaris with sun cc (sun studio 12) and gcc. and i compiled it in Debian with gcc as well. Then I dumped (disassembled) these 3 programs. I found that there were alway serveral nop instructions followed with the jmp instruction in the program generated by suncc. and this problem didn't exist in the other 2 program generated by gcc. err... Why does sun cc generate code using this pattern (a jmp followed by serveral nops)? For what? TIA Regards, TJ
