2019-01-16Move optimizations of bs_put* instruction to beam_ssa_optBjörn Gustavsson
Do the optimizations of bs_put* instructions in beam_ssa_opt and remove the beam_bs pass. This can lead to a slight improvement of compilation times.
2018-07-06Call test_lib:recompile/1 from init_per_suite/1Björn Gustavsson
Call test_lib:recompile/1 from init_per_suite/1 instead of from all/0. That makes it easy to find the log from the compilation in the log file for the init_per_suite/1 test case.

A literal negative size in binary construction would cause a crash.

2016-02-25Modernize use of timetrapsBjörn Gustavsson
Either rely on the default 30 minutes timetrap, or set the timeout using the supported methods in common_test.
2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.

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.
2013-06-14Fix binary construction on floating point middle-endian machinesJohannes Weißl
This complements 933e701 (OTP-10209). Without this patch the test cases "in_guard/1" and "coerce_to_float/1" in bs_construct_SUITE fail. The added lines in bs_construct_SUITE cover all branches that were not covered before (small and big numbers if BIT_OFFSET(erts_bin_offset) != 0).
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.
2012-10-09beam_utils: Extend live_opt/1 to recalculate live registers in allocsBjörn Gustavsson
The code generator uses conservative liveness information. Therefore the number of live registers in allocation instructions (such as test_heap/2) may be too high. Use the actual liveness information to lower the number of live register if it's too high. The main reason we want to do this is to enable more optimizations that depend on liveness analysis, such as the beam_bool and beam_dead passes.

2012-08-22compiler: Warn if the size of a binary segment is invalidBjörn Gustavsson
The compiler would silently accept and Dialyzer would crash on code like: <<X:(2.5)>> It is never acceptable for Dialyzer to crash. The compiler should at least generate a warning for such code. It is tempting to let the compiler generate an error, but that would mean that code like: Sz = 42.0, <<X:Sz>>. would be possible to compile with optimizations disabled, but not with optimizations enabled. Dialyzer crashes because it calls cerl:bitstr_bitsize/1, which crashes if the type of size for the segment is invalid. The easiest way to avoid that crash is to extend the sanity checks in v3_core to also include the size field of binary segments. That will cause the compiler to issue a warning and to replace the bad binary construction with a call to erlang:error/1. (It also means that Dialyzer will not issue a warning for bad size fields.)
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.
