This refactor was done using the unifdef tool like this:
for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done
where defile contained:
#define ERTS_SMP 1
#define USE_THREADS 1
#define DDLL_SMP 1
#define ERTS_HAVE_SMP_EMU 1
#define SMP 1
#define ERL_BITS_REENTRANT 1
#define ERTS_USE_ASYNC_READY_Q 1
#define FDBLOCK 1
#undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT
#define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0
#define ERTS_POLL_USE_WAKEUP_PIPE 1
#define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1
#undef ERTS_HAVE_PLAIN_EMU

These allow one to hash VM terms from NIF code.

erlang:hash/2 has been deprecated for a while, time to remove it.

* sverk/fix-list-length-int/OTP-13288:
erts: Fix error cases in enif_get_list_length
erts: Use Sint instead of int for list lengths
|
|
This removes the duplication in having both `cmp_eq`
and `CMP_EQ` and normalizes their name to uppercase.

Given the function definition below:
check(X) when X >= 0, X <= 20 -> true.
@nox has originally noticed that perfoming lt and ge
guard tests were performing slower than they should be.
Further investigation revealed that most of the cost
was in jumping to the erts_cmp function. This patch
brings the operations already inlined in erts_cmp
into the emulator, removing the jump cost.
After applying these changes, invoking the check/1
function defined above 30000 times with different
values from 0 to 20 has fallen from 367us to 213us
(measured as average of 3 runs). This is a
considerably improvement over Erlang 18 which takes
556us on average.
Floats have also dropped their time from 1126us
(on Erlang 18) to 613us.

This avoids potential integer arithmetic overflow for very large lists.

* Removed cmp_rel, cmp_rel_term and eq_rel

Bail out as soon as we find a diff between maps
if we are not interested in term order.
|
|
Strategy: Calculate an over estimation of heap size that will give
such a low probability for overflow, that "it will not happen".
Scary assumption 1: Uniformly distributed hash values.
Scary assumption 2: Tree size is normally distributed (right?)

This port has support for both non-smp and smp.
It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.

Commit d5c238473b9cec819d93faaef4ccc00ddb60465f added a third
argument to the cmp() function, but did not change the code generation
of native code that called cmp().
Name the new functions with an "erts_" prefix, and reinstate the
old cmp() function with two arguments.
We don't have to keep a cmp() function in the halfword emulator,
since HiPE does not support the halfword emulator.

Uses total order of types meaning int < float

for compile time argument checking

and change from Uint to UWord values
