Hello all: I have send the related issues to "http://gcc.gnu.org/bugzilla";, please check if you like, thanks.
currently, I only send 3 bugs: Bug58256, Bug58400, Bug58401, the other bugs may duplicate with these bugs, so I do not send (if they are also valuable, I will send too). Next, I should analyse them (better with another related members), my analyzing way is: compare it with another correct compiler (e.g x86 compiler) by code and by debugging. Wish one of these bugs can be fixed by us within a week (although I am not quite sure for it: I have no experience for compiler development). Welcome any members' suggestions or completions :-). Thanks.
