* bjorn/compiler/coverage:
sys_core_fold: Remove uncovered clauses matching #c_map{}
beam_z: Remove the uncovered to_typed_literal/1 function
Speed up running of compiler test suites in coverage mode
|
|
sys_core_fold:eval_element/3 attempts to evaluate calls to element/2
at compile time or to warn when the call will obviously fail. For
example:
element(1, [a])
will obviously fail and eval_element/3 will produce a warning.
eval_element/3 uses the helper functions is_not_integer/1 and
is_not_tuple/1 to test whether the arguments are known to be
incorrect. The clauses that attempt to match #c_map{} in those
helper function will never be executed, because #c_map{} will
never occur directly in an argument for a function call.
For example, code such as:
element(1, #{a=>Val})
will be translated to:
let <NewVar> = #{a=>Val}
in element(1, NewVar)
since maps are not considered safe (some map operations may
cause an exception at run time).

It was a workaround for a bug that has been fixed.

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.

Function name was somewhat confusing and when trying to find a better
name for it we realised it did not work as intended.

Always update prt->data with atomic xchg-op.
Check for NULL data to detect racing port terminator.
Use NULL, as THE_NON_VALUE can be a valid pointer on debug VM.

beam_utils:live_opt() is only invoked on code that has been
blockified by beam_block. Therefore the allocate/3 and
allocate_heap/4 instructions only occur in their transformed
form inside a block.
While we are it, correct a comment. 'asm' has been replaced
by 'from_asm'.
|
|
While we are it, also remove ?line macros in ref_opt_1/1 and correct
the indentation in do_ref_opt/2.
|
|
The compiler_bug/1 test case succeeded for the wrong reason. The
'asm' option is no longer supported (was ignored) and the compiler
looked for a .erl file.
Make sure that we don't fall for this trick again by making sure
that the error is reported from beam_validator.

io:put_chars(standard_error, [oops]) could previously crash the

Parsing invalid 'Set-Cookie' header would make httpc crash.
This commit filters invalid 'Set-Cookie' headers so that httpc wouldn't try to parse them.
|
|
core_lib:is_var_used/2 would not consider a variable used in the
value of a map pattern such as:
case Map of
#{key := <<42:N>>} -> ok
end
Here the variable 'N' would not be considered used.
It was assumed that there was no need to check map patterns at
all, since maps currently don't support variables in keys.
