2024-06-26	perf util: Make util its own library	Ian Rogers
	Make the util directory into its own library. This is done to avoid compiling code twice, once for the perf tool and once for the perf python module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.c are made part of this library.

2020-11-04	perf annotate mips: Add perf arch instructions annotate handlers	Dengcheng Zhu
	Support the MIPS architecture using the ins_ops association method. With this patch, perf-annotate can work well on MIPS.

2015-08-06	perf tools: Add empty Build files for architectures lacking them	Ben Hutchings
	perf currently fails to build on MIPS as there is no tools/perf/arch/mips/Build file. Adding an empty file fixes this as there are no MIPS-specific sources to build. It looks like the same is needed for Alpha and PA-RISC, though I haven't been able to test those.
