Subject: [PATCH 1/9] perf annotate: Fix annotation_calc_lines()
Date: Thu,  4 Apr 2024 10:57:08 -0700	[thread overview]
Message-ID: <20240404175716.1225482-2-namhyung@kernel.org> (raw)
In-Reply-To: <20240404175716.1225482-1-namhyung@kernel.org>

It should pass a proper address (i.e. suitable for objdump or addr2line)
to get_srcline() in order to work correctly.  It used to pass an address
with map__rip_2objdump() as the second argument but later it's changed
to use notes->start.  It's ok in normal cases but it can be changed when
annotate_opts.full_addr is set.  So let's convert the address directly
instead of using the notes->start.

Also the last argument is an IP to print symbol offset if requested.  So
it should pass symbol-relative address.

Fixes: 7d18a824b5e5 ("perf annotate: Toggle full address <-> offset display")
