Detailed Description

Unsigned integer type.

Represents any form of unsigned integer; the size of this integer is recorded in the width field.

Member Data Documentation

constant_qualified

bool unsignedbv_type2t::constant_qualified

Whether the source qualified this const, as #constant records it.

Unreflected: c_expr2string prints it and nothing else reads it, so two integers of the same width are the same type whether or not one was qualified (docs/roadmap/scope-clang-c-irep2.md §158).

cpp_type

irep_idt unsignedbv_type2t::cpp_type

The source language's own spelling of this type, as #cpp_type records it.

Unreflected: a spelling is no part of the type's identity, so two bitvectors of the same width are the same type however they were spelled. Carried because a consumer reads it back – python_converter:: get_python_type_category distinguishes a 1-char string element from an 8-bit int by it (docs/roadmap/scope-python-irep2.md §9).

excluded_field_bytes

std::size_t unsignedbv_type2t::excluded_field_bytes

staticconstexpr

Initial value:

=
    sizeof(irep_idt) + sizeof(bool)

field_names

std::string unsignedbv_type2t::field_names

static

Initial value:

=
  {"width", "", "", "", ""}

cpp_type pushes constant_qualified into a fresh slot, so this class now carries four bytes of trailing padding and fields_cover_class has no margin left: a further unreflected field would fit in the hole unnoticed.

Pin the size so the next one has to come here first.
