This worked out by accident since codegen never actually looks at
the arguments for 'succeeded'; it just assumes that they reference
the preceding instruction.

Replace deprecated <tt> with <code>

So we can see in travis which applications or options that is disabled,
(and/or other config problems)

So we know that libwxgtk3.0 exists.

Now that impossible branches are skipped altogether, it's no
longer possible to encounter get_tuple_element with a 'none'

By keeping track of the tag types in the exception handler list,
we can reject direct jumps to try_case handlers such as those
provoked by OTP-15945.
|
|
By removing 'succeeded' tests on setelement/3 when we know it
succeeds, all sequences that are eligible for set_tuple_element
will be nicely bundled in the same block, so we won't need to
bother with special try/catch handling.
The new version is slightly worse in the case where the first
setelement/3 is used to infer the tuple size as that call will
remain in its own block, but in practice this only occurs when
the user manually spells them out and I couldn't find any
examples of this in OTP or Elixir. It's equivalent for record
updates.

Only adding them when in try/catch worked, but made the exceptions
implicit and forced all later optimization passes to keep them in
mind. Making them explicit lets us simplify later passes.
|
|
The test case alters the return value of a function that the
compiler expects will never return, resulting in undefined
behavior.
Note that the debugger (which may change variables/return values)
is unaffected since the affected module is purged and "replaced"
with an interpreted variant.

Ensure that the stack slots are initialized when matching maps
|
|
* bjorn/compiler/fix-stack-init/ERL-1017/OTP-15968:
Ensure that the stack slots are initialized when matching maps
|
|
When matching a map, the compiler could fail to generate code that
would initialize all stack slots (Y registers) properly. Here is a
general outline of code that *could* cause this problem:
foo(Key, Map) ->
Res = case Map of
#{Key := Val} ->
%% Do something with Val here.
.
.
.
#{} ->
[]
end,
%% The stack slot for Val might not have been initialized
%% here if the key was not present in the map.
.
.
.
%% Use Res.
.
.
.
The code generator would wrongly assume that the map matching would
always initialize the stack slot, and if nothing else happened to
force that stack slot to be initialized, it would remain
uninitialized, which would likely crash the runtime system at the next
garbage collection.
`beam_validator` is supposed to find these kind of problems, but a bug
in `beam_validator` prevented it from detecting this problem.
