Clarify beam_load error message on file/module mismatch
|
|
erts: Add enif_term_type
|
|
This is particularly important in case insensitive filesystems,
where attempting to invoke a module with the wrong case leads
to confusing error messages:
1> erlpress_core:foo().
beam/beam_load.c(1428): Error loading module 'erlpress_core':
module name in object code is erlPress_core
Loading of erlPress_core.beam failed: :badfile
This commit replaces object code by BEAM file and improves
the readability of the message.

Many heap fragments do no longer make the GC slow.
Even worse, we are not guaranteed that a yield will provoke a GC
removing the fragments, which might lead to a one-yield-per-bucket
scenario if the heap fragment(s) still remains after each yield.

Use S operands instead of s operands for a slight speed increase
and reduction in code size of process_main(). Use micro instructions
for frequently executed instructions.
While at it, use safe multiplication in gen_get_integer() in
beam_load.c.
|
|
This helps avoid long sequences of enif_is_xxx in code that
serializes terms (such as JSON encoders) by letting the user
switch on the type.

Instead rely on gnu make's pre-defined RM variable which should

Let sys.h define HAVE_OVERFLOW_CHECK_BUILTINS if the compiler supports
__builtin_mul_overflow() and the other overflow checking builtins.
The test is intentionally made in a sys.h and not as a configure test.
On Windows, beam_emu.c is always compiled using gcc, but the other
files are usually compiled with Microsoft's C compiler. With the
test in the header file, HAVE_OVERFLOW_CHECK_BUILTINS will be defined
when compiling beam_emu.c.

Starting in OTP 19 (in commit 9504c0dd71d0), the compiler emits
a test_unit instruction instead of a skip instruction at the end
of binary. We can do the same replacement in the loader to get
rid of the i_bs_skip_bits_all2 instruction.
|
|
On a 64-bit architecture, the size of any binary that would fit in the
memory must fit in a small, so we can fail immediately if the size
term is not a small.
|
|
The new compiler required adding support for Y register for all
binary matching instructions. That was (intentionally) done in a
naive way that simplicated duplicated the entire body of each
instruction.
Now it's time to be less naive. Rewrite the binary matching
instructions using micro instructions. Because some of the binary
instructions are huge, that will significantly decrease the size of
process_main().
When compiling with clang, a huge process_main() would mess up
profile-guide optimization resulting in a significant performance
degradation. On my Mac, profile-guide optimzation would decrease
the estone benchmark by 100K estones (about 20 percent). This commit
gives me back the lost estones.
|
|
Mark the obsoleted instructions bs_start_match2, bs_save2, bs_restore2, and
bs_context_to_binary as cold.
Remove support of a Y operand for bs_save2 and bs_restore2.
|
|
get_tuple_element with an Y register has become more frequent with
the new compiler.
|
|
The compiler used to generate "move Literal y(Y)" instructions very
rarely. Therefore, there was a transformation to avoid having a "move
c y" instruction.
With the new compiler, "move Literal y(Y)" instructions are relatively frequent, so we will need a "move c y" instruction.

- Install of (mainly) documentation caused rebuild and
modification of the source tree even when the source
previously had been built. Also otp_patch_apply
modified the source tree when updating documentation.
This messed up the installation if installation was
performed by another user than the user that originally
built the system which not is an uncommon scenario.
- Some documentation was installed by copying files
instead of installing the files which caused faulty
access rights on files.
- The documentation was not properly updated when
applying a patch using otp_patch_apply.
