From a701d28e2d997705ae4376753af6e35b20029cef Mon Sep 17 00:00:00 2001 From: Dengcheng Zhu Date: Mon, 19 Oct 2020 15:21:24 +0800 Subject: perf annotate mips: Add perf arch instructions annotate handlers Support the MIPS architecture using the ins_ops association method. With this patch, perf-annotate can work well on MIPS. Testing it with a perf.data file collected on a mips machine: $./perf annotate -i perf.data : Disassembly of section .text: : : 00000000000be6a0 : : get_next_seq(): 0.00 : be6a0: lw v0,0(a0) 0.00 : be6a4: daddiu sp,sp,-128 0.00 : be6a8: ld a7,72(a0) 0.00 : be6ac: gssq s5,s4,80(sp) 0.00 : be6b0: gssq s1,s0,48(sp) 0.00 : be6b4: gssq s8,gp,112(sp) 0.00 : be6b8: gssq s7,s6,96(sp) 0.00 : be6bc: gssq s3,s2,64(sp) 0.00 : be6c0: sd a3,0(sp) 0.00 : be6c4: move s0,a0 0.00 : be6c8: sd v0,32(sp) 0.00 : be6cc: sd a5,8(sp) 0.00 : be6d0: sd zero,8(a0) 0.00 : be6d4: sd a6,16(sp) 0.00 : be6d8: ld s2,48(a0) 8.53 : be6dc: ld s1,40(a0) 9.42 : be6e0: ld v1,32(a0) 0.00 : be6e4: nop 0.00 : be6e8: ld s4,24(a0) 0.00 : be6ec: ld s5,16(a0) 0.00 : be6f0: sd a7,40(sp) 10.11 : be6f4: ld s6,64(a0) ...
