OK, thanks. I shall try to finish within this month (although I am not quite sure whether I can finish on time). >> >> >>> I'm confident that if the xtensa's patterns were fixed to abide by the rules >>> for matching constraints the problem in reload would not occur. >> >> >> Chen, perhaps a warming can be implemented for this in genrecog? > That would certainly be a welcome addition! > OK, thanks. May I firstly finish it before fixing xtensa pattern? I guess it is more easier than fixing xtensa patten. (I guess 'warming' is 'warning'.) By the way, can this patch "initialize several arrays before use them in find_reloads()" will cause correctness issue? (I guess not, it will skip optimization, but not cause correctness issue, and continue compiling). Thanks. -- Chen Gang Open, share, and attitude like air, water, and life which God blessed
