The following attributes describe the most common information for a
logical element. They help to identify the lexical scope level; the
element visibility across modules (global, local); the toolchain name
that produced the binary file.
and source language that produced the binary file.

May be explore the use of StringPool to store the Language string.
Basically, the setSourceLanguage function to use the logic from StringRef LVSourceLanguage::getName() to get the string and store it in the StringPool. And to get back the string in 'getSourceLanguage' query the StringPool.

That sounds promising, and a bit simpler, given the existing infrastructure.

However, in the current state of this PR, we could write a switch statement on the returned value of getSourceLanguage.getAs<...>(); this particular use case would become a bit harder to support if using strings as the underlying representation.

Initially, I thought this could be supported by exposing the LanguageIndex data member (suggested below), but this is not reliable, as it depends on the interning order.

We could still go for StringPool + LanguageIndex at the cost of having to do string comparisons somewhere else (I would prefer to avoid this).

I thought about this a bit and came to the conclusion that we could, either

  • (1) Leave as-is, using std::variant<Ts...>, perhaps with some additional improvement.
  • (2) Make LVSourceLanguage essentially an enum which contains enumerators for every language supported by any of the readers. We could use the most-significant bits to store the format that defines such language (e.g. DWARF, CodeView, etc.). This may be simple, as we can do something similar to
static constexpr unsigned LVTagDwarf = (0x01 << 16);
static constexpr unsigned LVTagCodeView = (0x02 << 16);

enum LVSourceLanguage : uint32_t {
  /* DWARF */
#define HANDLE_DW_LANG(ID, NAME, LOWER_BOUND, VERSION, VENDOR)                 \
  DW_LANG_##NAME = LVTagDwarf | ID,
#include "llvm/BinaryFormat/Dwarf.def"

  /* Codeview */
  ...
};

Then, the SourceLanguage becomes just a uint32_t. Essentially, this tries to represent the same as above, but without using std::variant<Ts...>, and possibly being more space-efficient.

  • (3) Relying on StringPool, as you suggested. Then, it may be a bit uncomfortable for debuginfologicalview library users to do something conditionally on the source language of a compile unit.

BTW, I tend to like (2) more, so if you also agree, I could switch to this option for the next revision.
