URL: https://github.com/llvm/llvm-project/commit/ba8ded6820fa610c7460fe86cd1f41f1df4bcc6c DIFF: https://github.com/llvm/llvm-project/commit/ba8ded6820fa610c7460fe86cd1f41f1df4bcc6c.diff LOG: [lldb] Don't check environment default char signedness when creating clang type for "char" With -f(un)signed-char, the die corresponding to "char" may be the opposite DW_ATE_(un)signed_char from the default platform signedness. Ultimately we should determine whether a type is the unspecified signedness char by looking if its name is "char" (as opposed to "signed char"/"unsigned char") and not care about DW_ATE_(un)signed_char matching the platform default.
