btrace: compute line range when printing
The "record function-call-history" command prints the range of source lines
for a function segment when given the /l modifier. This information is
computed for the entire execution history when processing the recorded branch
trace.
To speed up the initial trace processing, we compute the information when
we print a function segment and only if requested. The computation is fast
enough (due to the limited scope) that it is not worth storing the data in
struct btrace_function, anymore.
gdb/
* btrace.h (btrace_function) <lbegin, lend>: Remove.
* btrace.c (ftrace_debug): Do not print the line range.
(ftrace_skip_file, ftrace_update_lines): Remove.
(ftrace_new_function): Remove lbegin and lend initialization.
(btrace_compute_ftrace_bts): Remove call to ftrace_update_lines.
* record-btrace.c (btrace_compute_src_line_range): New.
(btrace_call_history_src_line): Call btrace_compute_src_line_range.
