Subject[PATCH V2 3/3] perf script: Improve srcline display for BTS
Date
Change the order of the output to put the srcline last.
e.g. old format:

4028fc main+0x2c (/bin/ls)
/build/buildd/coreutils-8.20/src/ls.c:1269 => 40d8a0 set_program_name+0x0 (/bin/ls)

new format:

4028fc main+0x2c (/bin/ls) => 40d8a0 set_program_name+0x0 (/bin/ls)
/build/buildd/coreutils-8.20/src/ls.c:1269
