Wrong result for
(X bsl WS) bxor Y.
where
X is any negative integer
Y is any integer that does not require more words than X
WS is erlang:system_info(wordsize) or larger
Fix: The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.

ERTS_PRINT_INVALID prevented file descriptor 0 to be used which
could cause an empty crash dump.

of a process with a matchstate on the stack.
|
|
If the process stack contained a match state
the print function would crash the vm as it was not
recognized by tag_val_def().
Add new MATCHSTATE_DEF returned by tag_val_def().
All other callers either ignore it or has a default
clause to handle invalid terms.

During code purging and check_process_code, the checking of the binary reference
embedded in the match binary state was omitted for the tracing tests. This would cause
the binary match state to reference deallocated memory.

Use '+hpds size' to set initial process dictionary size for spawned processes.

Comparison of exact terms could cause faulty term tests.
This was caused by a faulty (too small) internal type.
Symptom:
-1 = erts_internal:cmp_term(2147483648,0). %% wrong
Correct:
1 = erts_internal:cmp_term(2147483648,0).

The hipe_mfa_info_table lock is currently a mutex, causing
unnecessary contention and serialization of lookups for
apply-like constructs.
- change the lock from a mutex to an rwmutex
- split hipe_get_na_nofail_locked into a "try" path which
only needs a read lock, and a "slow" path which requires
a write lock
- reimplement hipe_get_na_nofail (used by apply ops etc) to
first call the "try" path with a read lock, and if that
fails the "slow" path with a write lock
- reimplement hipe_get_na_nofail_locked (used by maintenance
code) to call the "try" path and then optionally the "slow"
path, but without taking locks since its caller already has
the write lock
- adjust remaining lock ops to take/release full write lock
- use _rwlocked as suffix on functions requiring a write lock
- change hipe_mfa_get_trampoline to call get_locked not put_locked,
allowing it to take a read lock instead of a write lock
- change hipe_find_mfa_from_ra() to only take a read lock
