[PATCH] D56587: Fix sign/zero extension in Dwarf expressions.

[Markus Lavin via Phabricator via llvm-commits]

markus updated this revision to Diff 185542.
markus added a comment.

Dropping all the metadata stuff and specifying the bit size and type encoding directly in the expression vector. e.g.

  !DIExpression(DW_OP_convert, 8, 5, DW_OP_convert, 32, 5, DW_OP_stack_value)

This approach certainly has its advantages and require far less changes to existing code.
