The annotate browser is divided into 2 frames. Left frame contains 3
columns (some platforms only have one column).
For example:
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
While it's hard for user to understand what the data is.
This patch adds the titles "Percent", "IPC" and "Cycle" on columns.
Percent IPC Cycle │
│25 __attribute__((noinline))
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
The titles are displayed at row 0 of annotate browser if row 0 doesn't
have values of percent, ipc and cycle.
