+ <p>
+ Fix HiPE ErLLVM code generation for pattern matching with
+ UTF binaries.</p>
+ <p>
+ Own Id: OTP-13269</p>
+ </item>
+ <item>
+ <p>
+ Fix various binary construction inconsistencies for hipe
+ compiled code. <list> <item>Passing bad field sizes to
+ binary constructions would throw <c>badarith</c> rather
+ than <c>badarg</c>. Worse, in guards, when the unit size
+ of the field was 1, the exception would leak rather than
+ failing the function clause match.</item> <item>Passing
+ bignums as field sizes to binary constructions would
+ always fail (and always with <c>badarg</c>).</item>
+ <item>A bug in bs_init_bits that cased binary
+ constructions to fail with system_limit if they were at
+ least 1/8th of the actual limit.</item> <item>Compiler
+ crashes when matches against an integer literal whose
+ size fits an unsigned word, but not a signed word or
+ matches against an integer literal that whose size is
+ larger than the largest allowed bignum.</item> <item>Very
+ large binary constructions that should fail with
+ system_limit could instead fail with <c>badarg</c> or
+ even succeed with a faulty result.</item> <item>Add
+ missing check for unit size match when inserting a
+ binary. For example, a faulty expression like
+ <c>&lt;&lt;&lt;&lt;1:7&gt;&gt;/binary&gt;&gt;</c> would
+ succeed.</item> </list></p>
