From 14b83ac87608ab359f3913b86d31e6f02665f66d Mon Sep 17 00:00:00 2001

Subject: [PATCH] tools/bashreadline: fix probe for dynamically linked readline
Upstream-status: sent to https://github.com/bpftrace/bpftrace/pull/3564/
Fixes: bsc#1232536
When bash links against libreadline dynamically, the probe fails as the
readline symbol is undefined until runtime. Fix this issue by adding a
fallback probe that hooks directly into libreadline.

Subject: [PATCH 1/3] Drop support for LLVM 12 and below
LLVM 11 and below have been untested for a while.
Dropping LLVM 12 allows us to upgrade to C++ 20.
