Hi,
This is a rebased patch on trunk for PR78736. The last time, it got
stuck, because of warning issues with libgfortran, for which I filed
PR91593. The patch relegates the warning to Wextra instead, which only
triggers (non-fatal) warnings in libgfortran/io/transfer.c, and
survives bootstrap+test

This patch adds a new dg_require_effective_target procedure to the

whether a target supports calls to non-constant call targets.

This patch adds a new testsuite to gcc.target, with eBPF specific
tests.

This patch adds an eBPF port to libgcc.
As of today, compiled eBPF programs do not support a single-entry

Also, the BPF loaders in the kernel do not execute .in

You're right, t
My patch reorganizing using decl handling caused a regression in the
size of debug information. The culprit was that we were passing an
overload set when previously we'd pass a single decl. And that broke an
elision test.
Fixed by moving that test into the iteration of the overload set.
