184 they also output the source location information. 184 they also output the source location information. The @code{_loc} variants
185 take a @code{const dump_location_t &}. This class can be constructed from
186 a @code{gimple *} or from a @code{rtx_insn *}, and so callers can pass
187 a @code{gimple *} or a @code{rtx_insn *} as the @code{_loc} argument.
188 The @code{dump_location_t} constructor will extract the source location
189 from the statement or instruction, along with the profile count, and
190 the location in GCC's own source code (or the plugin) from which the dump
191 call was emitted. Only the source location is currently used.
192 There is also a @code{dump_user_location_t} class, capturing the
193 source location and profile count, but not the dump emission location,
194 so that locations in the user's code can be passed around. This
195 can also be constructed from a @code{gimple *} and from a @code{rtx_insn *},
196 and it too can be passed as the @code{_loc} argument.
