Hi Josh,
So adding config DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT to v5.19-rc2 got it working again for me on arm64. However commit dcea997beed6 ("faddr2line: Fix overlapping text section failures, the sequel") seems to be broken for me, below - this first appeared in rc3. Any idea what the issue could be?
$./faddr.sh hisi_sas_sata_done+0x8/0x38 hisi_sas_sata_done+0x8/0x38: fs mm ??:0
Thanks, John
