With qemu-2.11:
$ ~/inst-qemu/2.11.0/bin/qemu-sh4 test-pread
ret=1 errno=2
The value of errno is actually irrelevant here. So, the bug is fixed.

Title:
pread does not work right under qemu-sh4
Status in QEMU:
Fix Released
Bug description:
The pread system call returns a wrong value in some case, in a program
running under qemu-sh4 (version 2.9.0).
How to reproduce:
- Compile the program:
sh4-linux-gnu-gcc-5 -O -Wall -static -o test-pread test-pread.c
- Set environment variable for using qemu-sh4 (actually not needed, since the
program is statically linked here).
- ~/inst-qemu/2.9.0/bin/qemu-sh4 test-pread
Expected output:
ret=1 errno=0
Actual output:
ret=0 errno=2
test-pread.c:44: assertion 'ret == 1' failed
qemu: uncaught target signal 6 (Aborted) - core dumped
