Besides being noisy, they were already defined by a global Unix-
specific header, causing the Windows build to fail if one forgot to
define them.

It's bad style. Pass the name of the variable as an
extra argument to the macro.
|
|
try_case_end is an excepting-generating instruction that is
infrequently executed.

De-duplicate bignums in the literal pool
|
|
We KNOW that recv_set instruction is immediately followed
by a loop_rec instruction.

|
We don't need to pass x(0), x(1), and x(2) because they
can already be found in the register array.

Keep frequently used variables in machine registers.
|
|
We expect that:
* An arithmetic instruction is more likely to succeed
than to fail.
* An arithmetic instruction is more likely to have small
operands than bignum operands.
|
|
In a correct Erlang programs, we can expect that:
* A GC test instruction (such as test_heap) is more likely
not to do the GC.
* A BIF is more likely to succeed than to fail.
* A BIF is more likely to fail in a guard than in a body.
* An apply or fun call is likely to succeed.
Annotate conditions accordingly.

Instructions that used to be implemented in beam_emu.c
were not marked as cold as it would make no difference.
|
|
The bit syntax instructions are mixed among other instructions
in beam_hot.h and beam_cold.h.
Introduce a new hotness level called '%warm' with is associated
file beam_warm.h. Mark all bit syntax instructions as '%warm'.

such as a sub-binary, of a correct utf8 string,
that ends in the middle of a character.

Remove backward compatibility support for float literals
OTP-14575
|
|
Duplicate literals in the literal pool is a waste of memory.
Also, having unique literals can simplify some loader optimizations,
because we can known that if two literal indices are distinct, the
values must be distcint too.

Starting from R16B, floating point constants are stored
in the literal pool.
The backward compatibility support for the old representation
of floats has been kept long enough. Also, we might want to
ensure that all literals are unique in the future, and we certainly
don't want to update this code to ensure uniqueness.
