I have the IdentifierInfo for the macro to redefine, I have the tokens for the new definition of the macro.
How do I actually set the new tokens as the definition for the macro?
I’ve tried using MacroInfo::setTokens, and it’s not working.
I’ve also tried to use appendDefMacroDirective and it is also not working.
In a source file, you need to
#undef a macro before redefining it. Naively I’d suggest seeing what clang does with an
#undef followed by a new
(I really know very little about how the frontend works…)
No no no.
I’m making a new pragma called redefine_macro, it contains the name of the macro to redefine and the new definition.
How do I actually append the new definition to the macro history in Clang?
