This document describes the changes made to HiPE.

+
Hipe 3.7.6 + +
Improvements and New Features + + +

receive statements that can only read out a + newly created reference are now specially optimized so + that it will execute in constant time regardless of the + number of messages in the receive queue for the process. + That optimization will benefit calls to + gen_server:call(). (See gen:do_call/4 for + an example of a receive statement that will be + optimized.)

+ Various changes to dialyzer-related files for R14.

+

+ - Dialyzer properly supports the new attribute + -export_type and checks that remote types only refer to + exported types. A warning is produced if some + files/applications refer to types defined in modules + which are neither in the PLT nor in the analyzed + applications.

+

+ - Support for detecting data races involving whereis/1 + and unregister/1.

+

+ - More precise identification of the reason(s) why a + record construction violates the types declared for its + fields.

+

+ - Fixed bug in the handling of the 'or' guard.

+

+ - Better handling of the erlang:element/2 BIF.

+

+ - Complete handling of Erlang BIFs.

eprof has been reimplemented with support in + the Erlang virtual machine and is now both faster (i.e. + slows down the code being measured less) and scales much + better. In measurements we saw speed-ups compared to the + old eprof ranging from 6 times (for sequential code that + only uses one scheduler/core) up to 84 times (for + parallel code that uses 8 cores).

+

Note: The API for the eprof has been cleaned up + and extended. See the documentation.
