When debugging, it is important that we can trust the Core Erlang
pretty printer and Core Erlang parser.
|
|
|
|
This will speed up test cases that print all annotations.
|
|
|
|
If we pretty print to a file and read it back in, we expect to
get the same cerl data structures back.
|
|
Annotations would not be accepted for all constructs.
|
|
Make sure that we don't convert a map pattern to a map expression.

Dialyzer would warn about uses of the ?assert(BoolExpr) macro in assert.hrl
if the argument was known to be boolean-only.

While we are it, also re-ident the files.
|
|
We want to re-ident the source files after having taken out
all ?line macros. When re-indenting using Emacs, it's important
that comments that should be at the beginning of a line (or
follow the indentation of statements around it) must start with
"%%".

Either rely on the default 30 minutes timetrap, or set the timeout
using the supported methods in common_test.

interpretable/1 tests (among other things) that we are not allowed
to interpret modules in certain applications (such as kernel and
stdlib).
int:interpretable/1 as currently implement enforces the restriction
only in an installed system (the applications must have versions,
such as kernel-1.2.3).
We could modify int:interpretable/1 to enforce the restriction,
but it could sometimes be useful to be able to debug (for example)
erl_lint or other library modules that can safely be reloaded
without crashing the run-time system.
Therefore, assume that anyone working in a non-installed system
knows what they are doing and fix the test case so that it stop
failing in a non-installed system.

c7e82c6b406b teached the debugger to use the 'source' key
in Mod:module_info/1 to help locate the source code
corresponding to a BEAM file. The new test that was added
at the same time will fail if the test suites were
cross-compiled on another computer (i.e., the 'source' key
would not point to the source file on the target computer).
Avoid the problem by letting int_SUITE:init_per_suite/1 compile
the BEAM files. That will ensure that 'source' keys points to
the actual source file.

This performs a number of cleanups in the FP exception code:
- inline the body of unmask_fpe_conditional() in its only caller,
then delete the duplicated and identical definitions of it
- start the big processor-specific block with a comment describing
the two functions that must be defined, then delete redundant
comments at all the mask_*() functions
- add a comment before fpe_sig_action() explaining exactly what
processor-specific action is required of it
- flatten #ifdef nesting in fpe_sig_action()
- move common code in the x86 unmask_fpe() and erts_restore_fpu()
function into a subroutine
- minor tweaks: drop a redundant L suffix on a 0, add a comment
after an #else, bump the size of a debug buffer,
There should be no change in behaviour from these changes.

Remove some things that define-derived-mode does for us.
Also, derive erlang-mode from prog-mode, so that a user that has added
customizations meant for all programming language major modes will
enjoy those in Erlang mode as well.

that uses its own super carrier (erts_exec_mmapper)
to guarantee low addressed and executable memory (PROT_EXEC).
Currently only used on x86_64 that needs low memory
for HiPE/AMD64's small code model.
By initializing erts_exec_mapper early we secure
its low memory area before erts_literal_mmapper might
steal it.

to prepare for hipe native code allocation.
