2015-04-29beam_asm: Speed up encoding of large numbersBjörn Gustavsson
The misc_SUITE:integer_encoding/1 test case is annoyingly slow. Rewrite the encoding of integers in beam_asm to use the binary:encode_unsigned/1 BIF. Also tweak the test case itself. Scale the down the maximum size of the numbers being generated, but also add test of numbers around boundaries of power of two (which are the numbers most likely to expose bugs in the encoding).
2015-02-18beam_validator: Exit immediately on crashesBjörn Gustavsson
The beam_validator catches all exceptions and collect them. It makes more sense to don't catch 'error' and 'exit' exceptions, but to just print out the name of the current function and pass on the exception just as all other compilation passes do. Those kind of exceptions are the symptoms of the kind of severe but easily catched bugs that occur during development.
2015-01-26Speed up running of compiler test suites in coverage modeBjörn 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.
2015-01-09misc_SUITE: Cover the exception handling code in beam_deadBjörn Gustavsson
Amend the test suite to call beam_dead as originally intended (and not beam_block), and modify the input data so that the exception will occur within the try ... catch block in function/2.
2012-10-23compiler: Run testcases in parallelBjörn Gustavsson
Run testcases in parallel will make the test suite run slightly faster. Another reason for this change is that we want more testing of parallel testcase support in common_test.
2012-10-09Introduce the mandatory beam_a and beam_z passesBjörn Gustavsson
Introduce the mandary beam_a pass that will be run directly after code generation, and the mandatory beam_z pass that will be run just before beam_asm. Since these passes surround the optimizations, beam_a can (for example) do instruction renaming to simplify the optimization passes and beam_z can undo those renamings.

2012-08-15beam_type: Print the offending function if this pass crashesBjörn Gustavsson
2012-01-04Add the beam_except pass to optimize exceptionsBjörn Gustavsson
In order to save space, rewrite suitable calls to erlang:error/{1,2} to special BEAM instructions. This code is probably longer than the code taken out of v3_life and v3_codegen in the previous commit, but it is much easier to understand and maintain since the BEAM assembler format is better understood than the v3_life format.

2011-04-12compiler tests: Reinstate ?MODULE macro in calls to test_lib:recompile/1Björn Gustavsson
In 3d0f4a3085f11389e5b22d10f96f0cbf08c9337f (an update to conform with common_test), in all test_lib:recompile(?MODULE) calls, ?MODULE was changed to the actual name of the module. That would cause test_lib:recompile/1 to compile the module with the incorrect compiler options in cloned modules such as record_no_opt_SUITE, causing worse coverage.

2010-05-12Remove opaque declarations from the attributesBjörn Gustavsson
-opaque declarations should not be retained in the attributes (because they will be loaded along with the code and are not useful). While at it, filter away those Dialyzer attributes as early as possible - in v3_kernel.

* bg/opt-receive: Test that gen_server:call/2,3 are fast even with a huge message queue erts: Add tests for the receive optimization Update primary bootstrap erts: Implement recv_mark/1 and recv_set/1 for real compiler tests: Cover the error handling code in beam_receive compiler test: Test optimization of receive statements Optimize selective receives in the presence of a large message queue Introduce the new recv_mark/1 and recv_mark/1 instructions Compile tests that communicate with R12 nodes with the r12 option Move p_run/2 to test_lib gen: Inline wait_resp_mon/2 to help the compiler optimize OTP-8623 bg/opt-receive reveive statements that can only read out a newly created reference are now specially optimized so that it will execute in constant time regardless of the number of messages in the receive queue for the process. That optimization will benefit calls to gen_server:call(). (See gen:do_call/4 for an example of a receive statement that will be optimized.)
