2016-05-30	Eliminate unsafe use of Y registers	Björn Gustavsson
	If the Core Erlang optimization were turned off (using no_copt), the optimization passes for Beam assembly could generate unsafe code that did not initialize all Y registers before (for example) a call instruction. To fix this, beam_dead should not attempt to remove stores to Y registers. That is not safe if there is an exception-generating instruction inside a try...catch block.

	By first adding a call to error/1 to each uncovered line, QuickCheck could find test cases that would cover the lines.
2016-04-27	Move test cases from compilation_SUITE to beam_utils_SUITE	Björn Gustavsson
	beam_utils_SUITE didn't exist when the two test cases were written.

2015-01-26	Speed up running of compiler test suites in coverage mode	Björn Gustavsson
	I have spent too much time lately waiting for 'cover' to finish, so now its time to optimize the running time of the tests suite in coverage mode. Basically, when 'cover' is running, the test suites would not run any tests in parallel. The reason is that using too many parallel processes when running 'cover' would be slower than running them sequentially. But those measurements were made several years ago, and many improvements have been made to improve the parallelism of the run-time system. Experimenting with the test_lib:p_run/2 function, I found that increasing the number of parallel processes would speed up the self_compile tests cases in compilation_SUITE. The difference between using 3 processes or 4 processes was slight, though, so it seems that we should not use more than 4 processes when running 'cover'. We don't want to change test_lib:parallel/0, because there is no way to limit the number of test cases that will be run in parallel by common_test. However, there as test suites (such as andor_SUITE) that don't invoke the compiler at run-time. We can run the cases in such test suites in parallel even if 'cover' is running.
