Somewhere along the line, make eats up $ in user written input. This is surprising and annoying.

Here is the example from Igor where a simple $ had to be replaced by $$$$, to get the actual result -XX:CompileCommand=print,compiler.codegen.BMI2$BMITests::*

make test-only TEST='jtreg:test/hotspot/jtreg/compiler/codegen/BMI2.java' JTREG='VM_OPTIONS=-XX:+UnlockDiagnosticVMOptions -XX:-TieredCompilation -Xbatch -XX:CompileCommand=print,compiler.codegen.BMI2$$$$BMITests::*'
