- set print frame-arguements all - an Ada function named pck.call_me calls a C function named break_me - you put a breakpoint in break_me and the program reaches this breakpoint. Now display the backtrace: (gdb) bt #0 break_me () at [...] #1 0x000000000040243e in pck.call_me ( s={P_ARRAY = 0x7fffffffe21c, P_BOUNDS = 0x41e6e8}) at [...] whereas we should expect: (gdb) bt #0 break_me () at [...] #1 0x000000000040243e in pck.call_me (s="test") at [...] The problem is that GDB prints the S parameter in the pck.call_me Ada function using the current language, so the C one, because the program is stopped in a C function, whereas it should use the pck.call_me frame one. This behavior is ok when user manually changes the language but it's not the right one when language is auto. This patch fixes this problem so now when using auto language, all Ada frame arguments are printed using Ada like syntax when the frame is part of Ada code, even if the program is stopped in a frame using a different language. If the user explicitly sets a language (using "set language ...") then no change here, all the Ada frame arguments are printed using this language. gdb/ChangeLog: * ada-valprint.c (ada_val_print_gnat_array): Remove language parameter and use Ada language definition instead. (ada_val_print_ptr): Remove unused language parameter. (ada_val_print_num): Remove language parameter and use Ada language definition instead. (ada_val_print_enum, ada_val_print_flt): Remove unused language parameter. (ada_val_print_struct_union, ada_val_print_ref): Remove language parameter and use Ada language definition instead. (ada_val_print_1): Update all ada_val_print_xxx calls. Remove language parameter. (ada_val_print): Update ada_val_print_1 call. gdb/testsuite/ChangeLog: * gdb.ada/frame_arg_lang.exp: New testcase. * gdb.ada/frame_arg_lang/bla.adb: New file. * gdb.ada/frame_arg_lang/pck.ads: New file. * gdb.ada/frame_arg_lang/pck.adb: New file. * gdb.ada/frame_arg_lang/foo.c: New file. Tested on x86_64-linux, no regressions.
