perf annotate: Add missing newline on error message
If perf.data couldn't find vmlinux image for the given build-id, it would print error message. However it lacked a newline at the end, so the output looked like below: $ perf annotate --stdio No vmlinux file with build id 63b554b2e90f14a4bced200008865e757d3e8b36 was found in the path. Please use: perf buildid-cache -av vmlinux or: --vmlinux vmlinux Percent | Source code & Disassembly of a.out ------------------------------------------------ : : : : Disassembly of section .text: : : 00000000004004f4 <foo>: 0.00 : 4004f4: push %rbp 0.00 : 4004f5: mov %rsp,%rbp 0.00 : 4004f8: movl $0x0,-0x4(%rbp) 0.00 : 4004ff: jmp 400517 <foo+0x23> 14.70 : 400501: mov 0x200b28(%rip),%rax # 601030 <count> 0.02 : 400508: add $0x1,%rax 0.01 : 40050c: mov %rax,0x200b1d(%rip) # 601030 <count> 0.01 : 400513: addl $0x1,-0x4(%rbp) 13.92 : 400517: cmpl $0x98967f,-0x4(%rbp) 71.33 : 40051e: jle 400501 <foo+0xd> 0.00 : 400520: leaveq 0.00 : 400521: retq Fix it by adding a newline at the end of the message. It doesn't affect the tui output AFAICS.
