When run with '--no_spec', Typer will hide from Dialyzer any specs
present in the files under analysis.
|
|
|
|
Added ability to receive the set of exported types and report unknown ones.
While doing the above, cleaned up types, specs, and record field names.

The function xmerl_lib:expand_content/1 is mainly for expanding
Simple XML, but can also handle xmerl records. This patch fixes
an omission that caused expand_content/1 to not maintain the
'parents' list when expanding #xmlElement{} records.
No test cases written, since the xmerl test suites have not yet been
released.

* nick/orber/inet6_test_cases/OTP-9035:
OTP-9035 - More tests added so that Orber does not try to run IPv6 tests on a machine than cannot handle that. This only affect test code and not the application.

Changed year in copyright header.
Added updated modules to the appup file.
Improved error handling for ssh:connect/3/4.
Release note contained wrong ticker number.
OTP-8987 In some cases SSH returned {error, normal} when a channel was terminated unexpectedly. This has now been changed to {error, channel_closed}.

...

|
Use a binary instead of a string for the help text.
|
|
Since the error messages in the erl_posix_msg module are
presumably used very seldom, save memory by using binaries
instead of strings.
|
|
Frequency counts show that
move Const x(1)
move Const x(2)
are very common.
|
|
That will save one word and small amount of time for
each occurrence.
|
|
The is_eq_exact/3 and is_ne_exact/3 instructions are commonly used
with one immediate or literal operand.
Introduce three new specialized instructions:
i_is_eq_exact_literal/3
i_is_ne_exact_immed/3
i_is_ne_exact_literal/3
The i_is_ne_exact_literal/3 instruction is not very frequently
used, but its existence is justified because we removed in a
a previous commit the special instruction for matching bignums
and we now use i_is_ne_exact_literal/3 instead.
For consistency, rename the existing is_eq_immed/3 instruction to
is_eq_exact_immed/3.
While at it, remove the optimization of an is_eq/3 instruction
with an immediate operand because that optimization is already
done by the compiler.
|
|
Introduce a new i_increment/4 to optimize the addition of
a register and a small integer. This instruction saves two
instruction words compared to the standard instructions
(an i_fetch/2 instruction followed by a i_plus/3 instruction)
and will also be slightly faster.
|
|
The new instruction will save one word (because no size operand
is needed), and is slightly faster.
Handle select_tuple_arity in the same way.
|
|
|
|
Since the literal (constant) pool was introduced in R12, the
BEAM compiler will never generate a "put_list Const [] Dst"
instruction (it will instead generate a "move [Const] Dst"
instruction).
|
|
The move_sd specific instruction is no longer used since there
are specific move instructions covering all possible permutations
of operands. Also eliminate the move_cy instruction because it
is almost never generated by the compiler.
|
|
Create separate instructions for each register type. The "badmatch x(0)"
and "case_end x(0)" (which are very common) will only require a single
word each, compared to two words when GetArg1() is used.
|
|
Use separate instructions for each register type.
|
|
Use separate instructions for each register type.
|
|
|
|
Instead of having one i_select_val_sfI instruction that uses
the GetArg1() macro to fetch the controlling expression, use
three separate instructions for each of the register types.
That will save one word when selecting on the {x,0} register.
It should also be slightly faster since a conditional branch
is eliminated.
Although it seems that the BEAM compiler will never generate
a constant controlling expression (even with optimizations
turned off), we still make sure that they will work by
evaluating the select_val instruction at load time.
Handle the select_tuple_arity instruction in the same way.
|
|
The tmp_arg1 and tmp_arg2 variables are intended for transferring
values from the fetch/2 instructions to instructions such as
i_plus/3. In many places, however, tmp_arg1 and tmp_arg2 are used
as general temporary variables within a single instruction.
Improve the code generation by replacing sloppy use of tmp_arg1
and tmp_arg2 with block-local variables. In most cases, that will
allow the temporary values to be kept in registers.
