Measurements show that i_minus instructions (subtraction) are frequent enough to warrant creating specialized i_minus instructions. Thanks to José Valim for doing instruction counting on Elixir code.

2019-03-29Fix out of memory bug in the implementation of mapsKjell Winblad
This commit fixes a bug that could cause a crash or memory usage to grow until the machine ran out of memory when adding a key-value pair to a map. This could happen when inserting a new key-value pair with a key K1 containing a binary B1 into a map M having a key K2 with a binary B2 if the following conditions were met: * size(B1) >= 4294967296 * size(B2) >= 4294967296 * size(M) >= 32 * (size(B1) rem 4294967296) == (size(B2) rem 4294967296) * the first (size(B1) rem 4294967296) bytes are the same both in B1 and B2 * substituting B1 in K1 with B2 would result in a term with the same value as K2 The root cause of the bug is that the map implementation only hashed the first (X modulo 4294967296) bytes of binaries so that different binaries could get hashed to the same hash value independently of the hash seed.

2019-03-27erts: Remove unsafe bs_get_binary2 optimization from loaderJohn Högberg
A load-time optimization assumed that match contexts had no further uses when a bs_get_binary2 overwrote the match context's register, and figured it would be safe to reuse the match context's memory for the resulting binary. This is no longer safe as of OTP 22, as a match context may be reused after being passed to another function.
