Dump ISA into .cfg
The optimizing compiler dumps ISA features into .cfg which can be used
by the checker. A new tool perf2cfg needs to know ISA a CFG corresponds
to. The tool uses this to check that input perf data has the same ISA.
This CL implements in the compiler dumping ISA in addition to ISA features:
begin_compilation
name "isa:some_isa isa_features:feature1,-feature2"
method "isa:some_isa isa_features:feature1,-feature2"
date 1580721972
end_compilation
Bug: 147876827
Test: ./art/tools/checker/run_unit_tests.py
Test: test.py --target --optimizing --jit --interpreter
Test: test.py --host --optimizing --jit --interpreter
