  • Fix Orabug 33451471 and backport CTF/BTF enhancements
    ctfc: Free CTF container elements in ctfc_delete_container ()

    Reviewed-by: Jose E. Marchesi
    [8.5.0-3.0.1]
  • Merge the following oracle patches to OL8.5 beta:
  • Fix an aarch64 compilation error triggered by the oracle patch
    gcc9-multiple-changes-align.patch on OL8U5 source base.
    gcc-fix-aarch64-tune-params.patch
  • Fix Orabug 33281392 Update CTF and BTF support in OL8 GCC
    This commit brings the support for CTF/BTF debug formats at par with
    upstream. GCC now generates the CTF/BTF debug information by using the
    internal DWARF representation.
    For backward compatibility reasons, OL8 GCC continues to support -gt
    command line option.
