[Qemu-devel] [PATCH 2/6] linux-user/alpha: Add define for NR_shmat to enable shmat syscall |
Date: |

For historical reasons, the define for the shmat() syscall on Alpha is
NR_osf_shmat; however it has the same semantics as this syscall does
on all other architectures, so define TARGET_NR_shmat as well so that
QEMU's code for the syscall is enabled.
This patch brings our behaviour on the LTP shmat tests into line
with that for ARM (still not a perfect pass rate but not "this syscall
is completely broken" as we had before).
(Problem detected via a clang warning that the do_shmat() function
was unused on Alpha.)

Possibly other _osf_ syscalls need similar defines; somebody who
cares about Alpha might like to audit?
