Hafiz Abid Qadeer <abidh@codesourcery.com> gdb/ * tracepoint.h (validate_trace_state_variable_name): Declare. * tracepoint.c (validate_trace_state_variable_name): New. (trace_variable_command): Parse the trace state variable's name without using parse_expression. Do several validations. * mi/mi-main.c (mi_cmd_trace_define_variable): Don't parse the trace state variable's name with parse_expression. Validate it. gdb/testsuite/ * gdb.trace/tsv.exp: Adjust tests, and add a few more.
