[lldb-dev] target modules lookup

[Michael Sartain]

Is this supposed to work?

(lldb) target modules lookup -Av -s argc

It does nothing. Looking up the address of argc and using it also does
nothing.

(lldb) p &argc
(int *) $3 = 0x00007fff506c9458
(lldb) target modules lookup -Av -a 0x00007fff506c9458

It does work with the function "main":

(lldb) target modules lookup -Av -F main
1 match found in /home/mikesart/data/src/blah/build/blah:
        Address: blah[0x0000000000409970] (blah..text + 368)

       Function: id = {0x000003c9}, name = "main", range =

       Variable: id = {0x000003e6}, name = "argc", type= "int", location =

       Variable: id = {0x000003f4}, name = "argv", type= "char **",
location = DW_OP_fbreg(-16), decl = blah.cpp:159

As does using the address for "main".

(lldb) p main
(int (*)(int, char **)) $4 = 0x0000000000409970 (blah`main at blah.cpp:160)
(lldb) target modules lookup -Av -a 0x0000000000409970
      Address: blah[0x0000000000409970] (blah..text + 368)
      Summary: blah`main at blah.cpp:160
       Module: file = "/home/mikesart/data/src/blah/build/blah", arch =

  CompileUnit: id = {0x00000000}, file =

     Function: id = {0x000003c9}, name = "main", range =
[0x0000000000409970-0x000000000040a275)
     FuncType: id = {0x000003c9}, decl = blah.cpp:159, clang_type = "int

     Variable: id = {0x000003f4}, name = "argv", type= "char **", location
