Hello all: Sorry for disappearing several months, the reasons (excuses) are: - During these days, I am a little busy (although it is not a quite good excuse). - China Spring Festival (it maybe be a reason/excuse). - I blocked at cleanup-10.exe failure issue (build gcc/testsuite/gcc.dg /cleanup-10.c). I guess, this issue isn't quit complex to me, but it needs quite a few of my free time resources (e.g. several months) :-( At present, I let my tile qemu almost be a crashdump: dump full working flow (all insns and regs - 2G file, 34M lines), dump simple working flow (all insns - 82M file, 2M lines). check them with objdump and src code. I shall continue for it (for cleanup-10.exe issue firstly), and welcome any ideas, suggestions, and completions by any members. Thanks. -- Chen Gang (陈刚) Managing Natural Environments is the Duty of Human Beings.
