The HiPE compiler was leaking exceptions out of guards involving
binaries with `strange' arithmetic in them. Fixed by the set of
changes in this pull request.
|
|
Some more cases (taken from the BEAM bs_construct suite) that used to
show different behaviour than BEAM when compiled to native code were
included in the appropriate test file of the HiPE test suite.
|
|
This allows us to compile bs_match_int_SUITE with HiPE without a
system_limit crash.
|
|
Bugs were fixed in
hipe_rtl_binary_match:{first_part/3,make_size/3,set_high/1} in commit
5aea81c49, but it turns out these had been copy-pasted verbatim into
hipe_rtl_binary_construct, where they were causing further bugs. They
have now moved to hipe_rtl_binary, from where they are included by the
other two modules.
Furthermore, first_part/3 (reamed get_word_integer/3, since it loads
integers that fits into an unsigned word), and make_size/3 now accepts a
fourth argument to distinguish too large arguments (which should cause a
system_limit exception) from negative or non-integral arguments.
The use of first_part/3 (get_word_integer/3) from 5aea81c49 in
hipe_rtl_binary_construct now allows several binary construction
instructions to accept bignum sizes, as they were supposed to.
Additionally, calls to
hipe_rtl_binary_construct:check_and_untag_fixnum/3 were replaced with
get_word_integer/4 since all of them were also supposed to accept
sufficiently small bignums, but didn't, and check_and_untag_fixnum/3 was
essentially identical to first_part/3 anyway.
HiPE is now capable of passing bs_construct_SUITE completely unmodified.

Expressions like <<0:(fun(X)->X end(anka))>> would fail with 'badarith'
in HiPE, but 'badarg' in BEAM.
hipe_beam_to_icode was attempting to optimise the amount of code
generated by letting the arithmetic error propagate instead of
catching it. However, since it was emitting a block to throw 'badarg' in
that case anyway, we can just reuse it to achieve just as compact code
that behaves exactly like BEAM.

hipe_rtl_arith is only used by hipe_rtl_ssa_const_prop, which applies it
to any RTL, including RTL where the intent is to do unsigned math. Since
signed and unsigned operations produce the same 2's complement result,
this change is harmless.
On 32-bit architectures it caused HiPE crashes when compiling code like
<<0:((1 bsl 32)-1)>>, because the size of the field is too large to fit
in a signed integer.
|
|
The unit size field was previously completely discarded when lowering
this instruction from BEAM to Icode.
This feature was previously missing and expressions such as <<0,
<<1:1>>/binary>> would succeed construction when compiled with HiPE.

This feature was previously missing and expressions such as
<<<<1:1>>/binary>> would succeed construction when compiled with HiPE.
A primop is_divisible is introduced to handle the case when the unit
size is not a power of two.

Relying on double-precision floating-point arithmetic to compute the
log2 of an integer up to 64 bits long leads to rounding errors.

or fails
Also remove legacy debug macros and add help function httpd_util:error_log/2
to avoid code duplication.

Add a test to ensure that a single 'raw' option can be passed to
ssl:listen correctly.
Note: multiple raw options are (incorrectly) handled by
inet:listen_options. See

Add test that checks that the option inet_dist_listen_options is used
when starting a node with TLS distribution.
This test was adapted from inet_dist_options_options in
erl_distribution_SUITE.

Add test that checks that the options inet_dist_listen_min and
inet_dist_listen_max are used when starting a node with TLS
distribution.
|
|
The inet_dist_ options, such as min/max port numbers aren't used
with TLS distribution. This commits uses those settings in the
same way as they're used in inet_tcp_dist.erl

Some events are callbacks inside wxWidgets so idle processing doesn't
take place until operation is completed, for instance move/resize window
on Windows. This way we get some response while mouse button is pressed.

By default wxUSE_POSTSCRIPT is not enabled on Windows,
make it optional, postscript generation doesn't work that good
and is probably never used on windows anyway.
