link against libz. Under certain circumstances this
caused the build of OTP to fail.

OTP-14879 Application(s): erts
Fix bug in erlang:binary_to_integer/2 where invalid
characters were not detected for bases larger then 10.

not badarg as it should.
OTP-14890 Application(s): erts
Fixed bug in float_to_list/2 and float_to_binary/2 with
option decimals that caused a faulty rounding up of the
last decimal digit for about 6% of floats with a
fraction part.
For example, float_to_list(0.145, [{decimals,1}])
returned "0.2" instead of "0.1".
OTP-14891 Application(s): erts
Fix bug causing slow hipe execution in modules loaded
early during boot or loaded by code:atomic_load or
code:finish_loading.

formatting function that could be hit if specifying a
long floating-point format specifier to erts_sprintf or
similar.
OTP-14921 Application(s): erts
erlang:iolist_to_iovec/1 and enif_inspect_iovec will no
longer fail when provided with binaries that have been
matched-out on a non-byte boundary.

now badarg if supplied with a bitstring (without a
list).

Related Id(s): PR-1664
*** POTENTIAL INCOMPATIBILITY ***
Fix HiPE bug for binary constructs like <<X/utf8>>

crash.
This fix affects both the hipe compiler and erts
runtime in an *incompatible* way. Old hipe compiled
files need to be recompiled to load and run properly as

OTP-14886 Application(s): hipe
The BEAM compiler chooses not to perform tailcall
optimisations for some calls in tail position, for
example to some built-in functions. However, when the
ErLLVM HiPE backend is used, LLVM may choose to perform
tailcall optimisation on these calls, breaking the
expected semantics.
To preserve the precise semantics exhibited by BEAM,
the 'notail' marker, present in LLVM since version 3.8,
is added to call instructions that BEAM has not turned
into tail calls, which inhibits LLVM from performing
tail-call optimisation in turn.
