llvm-dwarfdump doesn't dump DW_FORM_exprloc/DW_AT_frame_base:
[hjl@gnu-6 bin]$ readelf -w debug.o | grep DW_AT_frame_base
<37> DW_AT_frame_base : 1 byte block: 56 (DW_OP_reg6 (rbp))
<5f> DW_AT_frame_base : 1 byte block: 56 (DW_OP_reg6 (rbp))
DW_AT_frame_base DW_FORM_exprloc
DW_AT_frame_base DW_FORM_exprloc
[hjl@gnu-6 bin]$ ./llvm-dwarfdump debug.o | grep DW_AT_frame_base
DW_AT_frame_base DW_FORM_exprloc
DW_AT_frame_base DW_FORM_exprloc
DW_AT_frame_base [DW_FORM_exprloc] (<0x1> 56 )
DW_AT_frame_base [DW_FORM_exprloc] (<0x1> 56 )
[hjl@gnu-6 bin]$
readelf can dump DW_AT_frame_base. llvm-dwarfdump only shows DW_FORM_exprloc.
