Support location tracking for built-in macro tokens
When a built-in macro is expanded, the location of the token in the
epansion list is the location of the expansion point of the built-in
macro.
This patch creates a virtual location for that token instead,
effectively tracking locations of tokens resulting from built-in macro
tokens.
libcpp/
* include/line-map.h (line_maps::builtin_location): New data
member.
(line_map_init): Add a new parameter to initialize the new
line_maps::builtin_location data member.
* line-map.c (linemap_init): Initialize the
line_maps::builtin_location data member.
* macro.c (builtin_macro): Create a macro map and track the token
resulting from the expansion of a built-in macro.
gcc/
* input.h (is_location_from_builtin_token): New function
declaration.
* input.c (is_location_from_builtin_token): New function
definition.
* toplev.c (general_init): Tell libcpp what the pre-defined
spelling location for built-in tokens is.
