It is allowed in Erlang/OTP 17 to redefine the map() types. However,
Dialyzer did not handle local map() types correctly.
|
|
hipe_rtl:phi_remove_pred/2 can produce a #move{} instruction with
floating-point temporaries as operands, even though such moves MUST
be #fmove{} instructions.
Added type checks to the #move{} and #fmove{} constructor and setter
functions to ensure that similar mishaps cannot happen again.
|
|
RTL can produce an #fconv{} instruction with an immediate operand, but
the backends unconditionally access the operand as a temporary. This
results in broken representation in the backends and eventually they
crash.

Also fixed some cases where Dialyzer could crash due to reaching
system limits.

This ticket is about records in Erlang code, and when to check the
fields against the (optional) types given when defining records.
Dialyzer operates on the Erlang Core format, where there are no trace
of records. The fix implemented is a Real Hack:
Given the new option 'dialyzer' erl_expand_records marks the line
number of records in a way that is undone by v3_core, which in turn
inserts annotations that can be recognized by Dialyzer.

dialyzer: Add Maps type mismatch test

When checking typed record fields Dialyzer failed to handle
types containing remote types.
Thanks to Erik Søe Sørensen for reporting this bug.

Add five new test files for maps in the HiPE test suite
Copy the tests for maps from the compiler application to a new HiPE test suite
Translate the put_map_assoc and put_map_exact BEAM instructions to ICode
Translate the has_map_fields and get_map_elements BEAM instructions to ICode

Change the maps_guard_fun test to accept the HiPE trace format.

Dialyzer sometimes output warnings like
Attempt to test for inequality between a term of type 'false' and a
term of opaque type 'false' | gb_set()
The reason was that erl_types:t_inf/3 when called from
erl_types:t_find_unknown_opaque() did not return 'false' but found the
mismatch. It should not return the mismatch unless the intersection is
empty ('none').
Thanks to Shayan Pooya [[email protected]] for pointing out the bug.

* yiannist/erllvm-fixes:
Fix frame size adjustment of stack descriptors
Fix counting of arguments of closures
Check for required LLVM version or issue error
|
|
* kostis/hipe-test-fix:
Add support for testing the LLVM backend too
Ensure generated modules are properly included in the Emakefile
|
|
In case of function calls with arguments that are passed to the stack,
the frame size of corresponding stack descriptors needs to be reduced by
the number of stack arguments. This commit fixes a bug in this
adjustment which was caused by an incorrect check.
|
|
Do not rely on MFA name for the arity of functions, since closures have
an extra argument. Instead, just use the length of the arguments list.
|
|
This checks that a required LLVM version (i.e. 3.4 or greater) appears in $PATH
when 'to_llvm' flag is used; in case of failure, abort compilation with an
error.
|
|
Namely, extend the HiPE tagging scheme info, properly handle the translation
of the (is_)map type test to Icode and RTL and support handling of the map()
type in the type system.
While at it, also performed some clean up of things that needed small fixes.

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.
|
|
Ensure all are "normal" versions according to the new version scheme
introduced in OTP 17.0
|
|
The (is_)constant/1 guard is removed from Erlang long ago and thus
there is no need to handle it in RTL.
While editing these files, also performed some minor cleanup.

* kostis/hipe-rc2-patch:
Cleanup and make sure warnings are treated as errors
Add specs for exported functions (to shut off a warning) and types in some record fields
Introduce and use a hipe_icode:icode() type
Substitude uses of lists:reverse(L1) ++ L2 with lists:reverse(L1, L2)

Add flags to enable and use the LLVM backend:
* to_llvm: use the LLVM pipeline for compilation (default optimization level
is O3),
* llvm_save_temps: save the intermediate files in current directory in order
to be able to debug or optimize the LLVM assembly,
* {to_llvm, O}: set the optimization level of LLVM opt and llc tools.
Add some debug support to the loader; no semantic change intented.
