From 9a4c8a3f2c753f4cee4bcbe23d28e23bbdb99e40 Mon Sep 17 00:00:00 2001 From: Alexander Gordeev <lasaine@lvk.cs.msu.su> Date: Thu, 7 Oct 2010 18:54:24 +0400 Subject: mips: fix errno setting after syscall If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...
