Changed in v2: - rename from warning_with_metadata_at to warning_meta - fix test plugins While C++ can have overloads, xgettext can't deal with overloads that have different argument positions, leading to two failures in "make gcc.pot": emit_diagnostic_valist used incompatibly as both --keyword=emit_diagnostic_valist:4 --flag=emit_diagnostic_valist:4:gcc-internal-format and --keyword=emit_diagnostic_valist:5 --flag=emit_diagnostic_valist:5:gcc-internal-format warning_at used incompatibly as both --keyword=warning_at:3 --flag=warning_at:3:gcc-internal-format and --keyword=warning_at:4 --flag=warning_at:4:gcc-internal-format The emit_diagnostic_valist overload isn't used anywhere (I think it's a leftover from an earlier iteration of the analyzer patch kit). The warning_at overload is used throughout the analyzer but nowhere else. Ideally I'd like to consolidate this argument with something constructable in various ways: - from a metadata and an int or - from an int (or, better an "enum opt_code"), so that the overload happens when implicitly choosing the ctor, but that feels like stage 1 material. In the meantime, fix xgettext by deleting the unused overload and renaming the used one. gcc/analyzer/ChangeLog: * region-model.cc (poisoned_value_diagnostic::emit): Update for renaming of warning_at overload to warning_meta. * sm-file.cc (file_leak::emit): Likewise. * sm-malloc.cc (double_free::emit): Likewise.

(warning_meta): ...this. (emit_diagnostic_valist): Delete decl of overload taking diagnostic_metadata. * diagnostic.c (emit_diagnostic_valist): Likewise for defn. (warning_at): Rename overload taking diagnostic_metadata to...
