MIPS: Setup errno for {f,l,}xstat
|
|
|
0b26f7 |
|
|
|
0b26f7 |
{f,l,}xstat stub for MIPS is using INTERNAL_SYSCALL
|
|
|
0b26f7 |
to do xstat syscall for glibc ver, However it leaves
|
|
|
0b26f7 |
errno untouched and thus giving bad errno output.
|
|
|
0b26f7 |
|
|
|
0b26f7 |
Setup errno properly when syscall returns non-zero.
