The GDB commands "info variables", "info functions", and "info types" show the appropriate list of definitions matching the given pattern. They also group them by source files. But no line numbers within these source files are shown. The line number information is particularly useful to the user when a simple "grep" doesn't readily point to a definition. This is often the case when the definition involves a macro, occurs within a namespace, or when the identifier appears very frequently in the source file. This patch enriches the printout of these commands by the line numbers and adjusts affected test cases to the changed output where necessary. The new output looks like this: (gdb) i variables All defined variables: File foo.c: 3: const char * const foo; 1: int x; The line number is followed by a colon and a tab character, which is then followed by the symbol definition. If no line number is available, the tab is printed out anyhow, so definitions line up. gdb/ChangeLog: * symtab.c (print_symbol_info): Precede the symbol definition by the line number when available. * NEWS: Advertise this enhancement. gdb/doc/ChangeLog: * gdb.texinfo (Symbols): Mention the fact that "info variables/functions/types" show source files and line numbers. gdb/testsuite/ChangeLog: * gdb.ada/info_types.exp: Adjust expected output to the line numbers now printed by "info var/func/type". * gdb.base/completion.exp: Likewise. * gdb.base/included.exp: Likewise. * gdb.cp/cp-relocate.exp: Likewise. * gdb.cp/cplusfuncs.exp: Likewise. * gdb.cp/namespace.exp: Likewise. * gdb.dwarf2/dw2-case-insensitive.exp: Likewise.
