I see the following in the Summary:
Type tag for CVR modifier type
C:
volatile int __attribute__((btf_type_tag("__b"))) b;
DWARF:
0x31: DW_TAG_variable
DW_AT_name ("b")
DW_AT_type (0x3c "volatile int")
0x3c: DW_TAG_volatile_type
DW_AT_type (0x45 "int")
0x41: DW_TAG_LLVM_annotation
DW_AT_name ("btf:type_tag")
DW_AT_const_value ("__b")
Basically, the btf_type_tag is put under 'volatile' type in dwarf. Is this what
gcc also agrees with?
