pwrite does not work right under qemu-sh4
The pwrite system call has no effect when writing to a non-zero file position, 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-pwrite test-pwrite.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-pwrite
Expected output:
buf = 01W3456789
Actual output:
buf = 0123456789
test-pwrite.c:56: assertion 'strcmp ("01W3456789",buf) == 0' failed
qemu: uncaught target signal 6 (Aborted) - core dumped
