perf annotate: Do not ignore call instruction with indirect target
Do not ignore call instruction with indirect target when its already identified as a call. This is an extension of commit e8ea1561952b ("perf annotate: Use raw form for register indirect call instructions") to generalize annotation for all instructions with indirect calls. This is needed for certain powerpc call instructions that use address in a register (such as bctrl, btarl, ...). Apart from that, when kcore is used to disassemble function, all call instructions were ignored. This patch will fix it as a side effect by not ignoring them. For example, Before (with kcore): mov %r13,%rdi callq 0xffffffff811a7e70 ^ jmpq 64 mov %gs:0x7ef41a6e(%rip),%al After (with kcore): mov %r13,%rdi > callq 0xffffffff811a7e70 ^ jmpq 64 mov %gs:0x7ef41a6e(%rip),%al Suggested-by: Michael Ellerman <mpe@ellerman.id.au> [Suggested about 'bctrl' instruction] Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Chris Riyder <chris.ryder@arm.com> Cc: Hemant Kumar <hemant@linux.vnet.ibm.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Markus Trippelsdorf <markus@trippelsdorf.de> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Naveen N.
