In order to be able to handle runtime library path in crypto
also DED parts was broken out into a macro.

When starting to implement DTLS, it was assumed that the APIs for TLS and
DTLS would differ more. This assumption turned out to be wrong.

- engine_load/3/4 can be called multiple times for same engine
if it allows it (eg doesn't contain global data)
- ensure_engine_loaded/2/3 is new functions that guarantees that the engine
is just loaded once by adding it to OpenSSL internal engine list and check that
before loading.
- ensure_engine_unloaded/1/2 is new functions that is used to unload engines loaded with
ensure_engine_loaded (remove it from OpenSSL internal engine list and then unload).
- new utility functions engine_by_id/1, engine_add/1, engine_remove/1,
engine_get_id/1 and engine_get_name/1

The doc says the default kernel logger_level is info, it should be notice.

Index records for bag tables with ram_copies was not deleted
after "real" objects where deleted and thus a memory leak.

If one of the destination registers for get_map_elements is
the same as the map source, extract that element last.

This optimization can be better done in the SSA format before
code generation.
|
|
The removal of redundant bs_restore2 instructions is done easier
on the SSA format. Keep the rest of the optimizations, because
they are easier to do on the BEAM instructions.
|
|
As a preparation for replacing v3_codegen with a new code generator,
remove unsafe optimization passes. Especially the older compiler
passes have implicit assumptions about how the code is generated.
Remove the optimizations in beam_block (keep the code that creates
blocks) because they are unsafe. beam_block also calls
beam_utils:live_opt/1, which is unsafe.
Remove beam_type because it calls beam_utils:live_opt/1, and also
because it recalculates the number of heaps words and number of live
registers in allocation instructions, thus potentially hiding bugs in
other passes.
Remove beam_receive because it is unsafe.
Remove beam_record because it is the only remaining user
of beam_utils:anno_defs/1.
Remove beam_reorder because it makes much more sense to run it
as an early SSA-based optimization pass.
Remove the now unused functions in beam_utils:
anno_def/1
delete_annos/1
is_killed_block/2
live_opt/1
usage/3
Note that the following test cases will fail because of the
removed optimizations:
compile_SUITE:optimized_guards/1
compile_SUITE:bc_options/1
receive_SUITE:ref_opt/1
|
|
|
|
This will enable more optimizations.

|
Don't match exact BEAM instructions when trying to recognize
function_clause exceptions that should be replaced with a jump to the
func_info instruction. Instead, do a symbolic evaluation of the list
building code and see if the result is a list of the argument
registers.
While at it, also teach fix_block_1/2 to completely remove a test_heap
instruction before an exception generation instruction.
|
|
Smarter code generation means that beam_validator must
be smarter too. In the following example, beam_validator
must be able to infer that y0 refers to a map:
move x0 y0
test is_map L1 x0
%% Here the type for y0 must be 'map'.
|
|
|
|
The func_info instruction does not expect a stack frame. There will
be an assertion failure in the debug-compiled runtime system.
|
|
|
|
If we transfer state appropriately to labels that can't be reached,
the state could taint other labels.
|
|
Since the compiler will start optimizing more aggressively, beam_validator
must keep up and improve the recognization of tuples and maps.
|
|
The new code generator will more aggressively reuse registers,
so we must be more careful about updating the state for try/catch.
In particular, an "empty" try/catch that can't throw an
exception must not update the try/catch state.

Nicer to read and less confusion.
