Subject: linux-user/nios2: Use force_sig_fault for EXCP_DEBUG
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3a0a43ec3c9c4c26f5a1a948e78311468e2930d6;p=qemu.git

linux-user/nios2: Use force_sig_fault for EXCP_DEBUG

Use the simpler signal interface, which forces us to supply
the missing PC value to si_addr.
