Hi Tom,

This series contains a few clang-14 fixes to partly resolve the problems shown by [1].
The event_dump problem is that the symbol name is not printed by addr2line even though it seems to be present:
Without LTO:
$ addr2line -e u-boot.clang14.no-lto 4a37f addr2line: DWARF error: invalid or unhandled FORM value: 0x23 vbe_simple.c:?
$ nm u-boot.clang14.no-lto |grep 4a37f 000000000004a37f t bootmeth_vbe_simple_ft_fixup
With LTO is even worse:
$ addr2line -e u-boot.clang14.lto 2d2ee0 addr2line: DWARF error: invalid or unhandled FORM value: 0x23 ??:0
$ nm u-boot.clang14.lto |grep 4dad1 000000000004dad1 t bootmeth_vbe_simple_ft_fixup
Perhaps this is a bug in addr2line or the clang DWARF output?
I should have mentioned that I can respin the series to deal with this, perhaps by not requiring the function name to be present when clang is used (or just at all?)
Plus I have one more patch to add for the LTO stuff.
Let me know what you think and I can respin this this.
