[Bug go/83308] Missing platform definitions for SH in libgo

2017-12-07 Thread ian at airs dot com
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83308 --- Comment #4 from Ian Lance Taylor --- gccgo does work on a number of targets that do not have split stack support. The downsides are that each goroutine has a much larger stack, and if you have too much recursion you can run out of stack spac

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83314 --- Comment #1 from Ian Lance Taylor --- errno 9 is EBADF, which doesn't make much sense since libgo only ever calls mmap with MAP_ANONYMOUS. And I'm not even sure where those messages are coming from. I don't see any place where the GCC 7 libg

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83314 --- Comment #2 from James Clarke --- My guess is libbacktrace/mmapio.c (perhaps mmap.c), which calls mmap with MAP_PRIVATE, and calls `error_callback (data, "mmap", errno)` on failure. That's a function pointer, which I would assume is error_call
