Subject: [PATCH 14/29] perf annotate: Support jump instruction with target as second operand
Date: Tue, 20 Dec 2016 14:03:43 -0300 [thread overview]
Message-ID: <20161220170358.4350-15-acme@kernel.org> (raw)
In-Reply-To: <20161220170358.4350-1-acme@kernel.org>
From: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com>
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)
