rev 52509 : [mq]: graal

*** 1,10 ****
! Turn on the benchmark counters, and listen for specific patterns on System.out/System.err.
! The format of this option is:
  
    (err|out),start pattern,end pattern
    
  You can use "~" to match 1 or more digits.
  Examples:
  
    err, starting =====, PASSED in
    out,Iteration ~ (~s) begins:,Iteration ~ (~s) ends:

! Turn on the benchmark counters. The format of this option is:
  
    (err|out),start pattern,end pattern
    
+ Start counting when the start pattern matches on the given stream and stop when the end pattern occurs.
  You can use "~" to match 1 or more digits.
  Examples:
  
    err, starting =====, PASSED in
    out,Iteration ~ (~s) begins:,Iteration ~ (~s) ends:
*** 20,24 ****

  The JVMCICounterSize value depends on the granularity of the profiling -
  10000 should be sufficient. Omit JVMCICountersExcludeCompiler to exclude
  counting allocations on the compiler threads.
  The counters can be further configured by the ProfileAllocationsContext option.
+ 
+ We highly recommend the use of -Dgraal.AbortOnBenchmarkCounterOverflow=true to
+ detect counter overflows eagerly.
