Message-ID: <20261102165837.24591-10-kaloz@kernel.org>

Subject: [PATCH 09/10] add sparc64 port
This uses the clone, rt_sigaction, ipc, suseconds_t, MC_NPC, PLT write
and local symbol hooks. The thread pointer is %g7, fenv_t is the whole
%fsr, and long double is quad precision. Long double arithmetic is done
in software by the _Qp_* helpers.
