I am trying to use the getPreviousToken function from
clang-tools-extra<https://github.com/llvm/llvm-project/tree/master/clang-tools-extra>/clang-tidy<https://github.com/llvm/llvm-project/tree/master/clang-tools-extra/clang-tidy>/utils<https://github.com/llvm/llvm-project/tree/master/clang-tools-extra/clang-tidy/utils>/LexerUtils.cpp,
but am having issues when the SourceLocation comes from a macro. Let’s say I
have the following functions:
#include <Kokkos_Core.hpp>
#include <string>
// The macros are defined such that KOKKOS_FUNCTION is empty and
KOKKOS_INLINE_FUNCITON = “inline”
KOKKOS_FUNCTION
void useString(std::string const& s, int i){ }
KOKKOS_INLINE_FUNCTION
void useString2(std::string const& s, int i){ }
If I take the FunctionDecl for useString and use getBeginLoc, I will get a
location that corresponds to the token void right before useString, I then use
getPreviousToken to find the KOKKOS_FUNCTION macro and all is well.
But if I call getBeginLoc on useString2 my location starts off in the macro
(I’m not really sure exactly what that means, my guess is that it starts on the
inline keyword) and if I use that location for getPreviousToken, I don’t get
the ‘}' from the line with useString, instead I get some location from other
headers included in Kokkos_Core.hpp. I don’t think that this is the intended
behavior, but I don’t have a minimal working example at the moment. I did track
it down to where getPreviousToken calls getWithOffset(-1) on the source
location and it is that new location which is the unexpected location.
Any help would be appreciated.
