There is duplicated effort in that validate_integer() checks
whether the integer value is valid, and then normalize_integer()
does mostly the same work in order to convert the value to an
integer.
Eliminate the validate_integer() function and incorporate
its checks into normalize_integer(). Also produce proper
error messages.

Class names must start with an uppercase letter and only contain
uppercase letters, digits, or hyphens. The parser will not allow
class names that don't start with an uppercase letter, so we don't
have to check that.
|
|
We only tested that ValueTest.asn1 would compile, no that the
values were correct.
|
|
Don't build a record using the tuple syntax. It is bad in case
we would want to change the record definition later.

* bjorn/compiler/beam_dead/OTP-12393:
Update the comments that explain what beam_dead does
Improve optimization of bs_start_match2
Extend count_bits_matched/3 to handle the UTF instructions
misc_SUITE: Cover the exception handling code in beam_dead
Generalize optimizations using shortcut_rel_op/4
beam_dead: Optimize branches from relational conditionals
|
|
|
|
|
|
While we are, clean up the comments and rearrange the code for
clarity. Also add a test to cover the last uncovered line in
beam_dead.erl.
|
|
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.
|
|
Better optimizations with less code.

The BEAM compiler translates code such as:
is_hex_digit(D) when $0 =< D, D =< $9 -> true;
is_hex_digit(D) when $a =< D, D =< $z -> true;
is_hex_digit(D) when $A =< D, D =< $Z -> true;
is_hex_digit(_) -> false.
to something like this:
L0: test is_ge L1 {x,0} 48
test is_ge L1 57 {x,0}
move true {x,0}
return.
L1: test is_ge L2 {x,0} 97
test is_ge L2 122 {x,0}
move true {x,0}
return
L2: test is_ge L3 {x,0} 65
test is_ge L3 90 {x,0}
move true {x,0}
return
L3: move false {x,0}
return
We can see that tests will be repeated even if they cannot possibly
succeed. For instance, if we pass in {x,0} equal to 32, the first
test that {x,0} is greater than or equal to 48 at L0 will fail.
The control will transfer to L1, where it will be tested whether
{x,0} is greater than 97. That test will fail and control
will pass to L2, where again the test will fail.
The compiler can do better by short-circuiting repeating tests:
L0: test is_ge L3 {x,0} 48
test is_ge L1 57 {x,0}
move true {x,0}
return.
L1: test is_ge L2 {x,0} 97
test is_ge L3 122 {x,0}
move true {x,0}
return
L2: test is_ge L3 {x,0} 65
test is_ge L3 90 {x,0}
move true {x,0}
return
L3: move false {x,0}
return

This commit improves crash dumps in several ways:
* Suspends schedulers to get a current snapshot
* Dumps information about scheduler
* Dumps stack trace of current running process
(including Garbing processes)
|
|
Also removed old legacy fallback that is no longer used
|
|
These functions allow any thread to suspend any other thread
immediately and then resume all threads. This is useful when
doing a crash dump in order to get a more accurate picture
of what state the system is in.
