| |
This adds a new 'dsoff' field to print dso offset for resolved symbols, and the offset is appended to dso name.
Default output: $ perf script ls 2695501 3011030.487017: 500000 cycles: 152cc73ef4b5 get_common_indices.constprop.0+0x155 (/usr/lib/x86_64-linux-gnu/ld-2.31.so) ls 2695501 3011030.487018: 500000 cycles: ffffffff99045b3e [unknown] ([unknown]) ls 2695501 3011030.487018: 500000 cycles: ffffffff9968e107 [unknown] ([unknown]) ls 2695501 3011030.487018: 500000 cycles: ffffffffc1f54afb [unknown] ([unknown]) ls 2695501 3011030.487018: 500000 cycles: ffffffff9968382f [unknown] ([unknown]) ls 2695501 3011030.487019: 500000 cycles: ffffffff99e00094 [unknown] ([unknown]) ls 2695501 3011030.487019: 500000 cycles: 152cc718a8d0 __errno_location@plt+0x0 (/usr/lib/x86_64-linux-gnu/libselinux.so.1)
