perf annotate: Support jump instruction with target as second operand
Architectures like PowerPC have jump instructions that includes a target address as a second operand. For example, 'bne cr7,0xc0000000000f6154'. Add support for such instruction in perf annotate. objdump o/p: c0000000000f6140: ld r9,1032(r31) c0000000000f6144: cmpdi cr7,r9,0 c0000000000f6148: bne cr7,0xc0000000000f6154 c0000000000f614c: ld r9,2312(r30) c0000000000f6150: std r9,1032(r31) c0000000000f6154: ld r9,88(r31) Corresponding perf annotate o/p: Before patch: ld r9,1032(r31) cmpdi cr7,r9,0 v bne 3ffffffffff09f2c ld r9,2312(r30) std r9,1032(r31) 74: ld r9,88(r31) After patch: ld r9,1032(r31) cmpdi cr7,r9,0 v bne 74 ld r9,2312(r30) std r9,1032(r31) 74: ld r9,88(r31) 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: Kim Phillips <kim.phillips@arm.com> Cc: Markus Trippelsdorf <markus@trippelsdorf.de> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Naveen N.
