Subject: Re: ERROR: INT DW_ATE_unsigned_1 Error emitting BTF type

Some post-mortem:

LLVM_DWARF_BIN="/opt/llvm-toolchain/bin/llvm-dwarfdump"

module="drivers/net/ethernet/mellanox/mlx5/core/mlx5_core.ko"

Module has DW_ATE_unsigned_160 and DW_ATE_unsigned_1:

$LLVM_DWARF_BIN $module | grep DW_AT_name | grep DW_ATE_ | sort -u
               DW_AT_name      ("DW_ATE_signed_32")
               DW_AT_name      ("DW_ATE_signed_64")
               DW_AT_name      ("DW_ATE_unsigned_1")
               DW_AT_name      ("DW_ATE_unsigned_128")
               DW_AT_name      ("DW_ATE_unsigned_16")
               DW_AT_name      ("DW_ATE_unsigned_160")
               DW_AT_name      ("DW_ATE_unsigned_32")
               DW_AT_name      ("DW_ATE_unsigned_64")

vmlinux has only DW_ATE_unsigned_1:

$ $LLVM_DWARF_BIN vmlinux | grep DW_AT_name | grep DW_ATE_ | sort -u
               DW_AT_name      ("DW_ATE_signed_1")
               DW_AT_name      ("DW_ATE_signed_16")
               DW_AT_name      ("DW_ATE_signed_32")
               DW_AT_name      ("DW_ATE_signed_64")
               DW_AT_name      ("DW_ATE_signed_8")
               DW_AT_name      ("DW_ATE_unsigned_1")
               DW_AT_name      ("DW_ATE_unsigned_128")
               DW_AT_name      ("DW_ATE_unsigned_16")
               DW_AT_name      ("DW_ATE_unsigned_24")
               DW_AT_name      ("DW_ATE_unsigned_32")
               DW_AT_name      ("DW_ATE_unsigned_40")
               DW_AT_name      ("DW_ATE_unsigned_64")
               DW_AT_name      ("DW_ATE_unsigned_8")
