This is just a preparation to allow detection of older nodes
that do not understand maps (R16 and older).

to be: 116,Arity, K1,V1,K2,V2,...,Kn,Vn
instead of: 116,Arity, K1,K2,...,Kn, V1,V2,....,Vn
We think this will be better for future internal map structures
like HAMT. Would be bad if we need to iterate twice over HAMT
in term_to_binary, one for keys and one for values.

b08ffc15e1d9ad105dd6385bbac41c97c09b48bc corrected a bug,
but violated the types by passing a c_apply() when a
c_let() was expected. That happened to work, but Dialyzer
was not amused.

Allow all init_per_[suite|group|testcase] to throw (or exit)
{skip, Reason} to explicitly ignore tests without failing.
It is easier to catch it in one place instead of writing a try
in each init_per_* to return {skip, Reason}.

A note has been added that clarifies that the encoding of
the I/O-server has to be set explicitly, irrespective of
any encoding comment.

file:set_cwd/1 accepts binaries as arguments, however the binaries
must be properly encoded as per file:native_name_encoding/0.
Also update the note under no_translation error to refer that passing
a ISO-latin-1 encoded binary under any unicode file name encoding.

Boolean case expressions with redundant clauses could make the compiler
crash:
case X == 0 of
false -> no;
false -> no;
true -> yes
end.

Wrong order of arguments in httpc_handler:update_session/4 error
handling code should not result in bad_argument error making
stack trace unusable.

The following code could crash the compiler:
f(X = true) when X or true or X -> ok.

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.

Extend the 'rtl_var' definition to host liveness information needed for
a simple liveness analysis performed by the LLVM backend.
Also, uncomment some function definitions (mostly simple accessors) that
are already there and are useful for the translation of RTL code to LLVM
assembly.
Finally, extend the RTL 'call' instruction with the 'normalcontinuation'
field which is required for translating calls that are in the scope of
an exception handler. This extra field is required in order to point to
a new basic block which will hold the 'unwind label' of LLVM's invoke
instruction. While the 'unwind label' is semantically equivalent with
the 'failcontinuation', in LLVM this block must have a 'landingpad'
instruction. The problem arises by the fact that an RTL 'continuation'
block can also be accessible by other paths in the RTL CFG, and so
cannot be marked as a landing pad. To overcome this issue we create a
new block (the 'normalcontinuation') which is used as the 'unwind label'
of LLVM's invoke instruction and which will eventually transfer control
to the 'continuation' block.

This is used by the LLVM backend in order to generate unique names for
temporary SSA values and functions.

All backends (e.g. arm, ppc, sparc, x86) share the same code for the following
functions:
* find_const/2,
* mk_data_relocs/2, and
* slim_sorted_exportmap/3
This commit moves those definitions (along with some helper functions) in
misc/hipe_pack_constants.erl and adds the appropriate specs. This is a
structural change; no change in semantics intented.

erl_lint has since R13B emitted warnings whenever any of the types
arity(), bitstring(), iodata(), or boolean() were re-defined. Now
errors are emitted instead.
|
|
Since Erlang/OTP R16B the linter has not emitted warnings when
built-in types were re-defined. This bug has been fixed.
Thanks to Roberto Aloi for reporting the bug.
