On the default configuration, it causes a build failure (unless "--disable-werror" is specified). The only extra_lines use in arrange_linetable function is removed on the commit 558802e4d1c5dcbd0df7d2c6ef62a6deac247a2f ("gdb: change subfile::line_vector to an std::vector"). So, this variable should be removed to prevent a build failure. gdb/ChangeLog: * xcoffread.c (arrange_linetable): Remove unused extra_lines. --- gdb/xcoffread.c | 8 -------- 1 file changed, 8 deletions(-) base-commit: 58d69206b8173b9d027a6c65f56cdaf045ae6e64 diff --git a/gdb/xcoffread.c b/gdb/xcoffread.c index b7d65771115..aa88cbc724d 100644 --- a/gdb/xcoffread.c +++ b/gdb/xcoffread.c @@ -419,8 +419,6 @@ add_stab_to_list (char *stabname, struct pending_stabs **stabvector) static void arrange_linetable (std::vector &old_linetable) { - int extra_lines = 0; - std::vector fentries; for (int ii = 0; ii < old_linetable.size (); ++ii) @@ -436,12 +434,6 @@ arrange_linetable (std::vector &old_linetable) e.line = ii; e.is_stmt = 1; e.pc = old_linetable[ii].pc; - - /* If the function was compiled with XLC, we may have to add an - extra line entry later.
