* rickard/ethread-rewrite/OTP-8544: Rewrite ethread library
2010-08-10Rewrite ethread libraryRickard Green
Large parts of the ethread library have been rewritten. The ethread library is an Erlang runtime system internal, portable thread library used by the runtime system itself. Most notable improvement is a reader optimized rwlock implementation which dramatically improve the performance of read-lock/read-unlock operations on multi processor systems by avoiding ping-ponging of the rwlock cache lines. The reader optimized rwlock implementation is used by miscellaneous rwlocks in the runtime system that are known to be read-locked frequently, and can be enabled on ETS tables by passing the `{read_concurrency, true}' option upon table creation. See the documentation of `ets:new/2' for more information. The ethread library can now also use the libatomic_ops library for atomic memory accesses. This makes it possible for the Erlang runtime system to utilize optimized atomic operations on more platforms than before. Use the `--with-libatomic_ops=PATH' configure command line argument when specifying where the libatomic_ops installation is located. The libatomic_ops library can be downloaded from: http://www.hpl.hp.com/research/linux/atomic_ops/ The changed API of the ethread library has also caused modifications in the Erlang runtime system. Preparations for the to come "delayed deallocation" feature has also been done since it depends on the ethread library. Note: When building for x86, the ethread library will now use instructions that first appeared on the pentium 4 processor. If you want the runtime system to be compatible with older processors (back to 486) you need to pass the `--enable-ethread-pre-pentium4-compatibility' configure command line argument when configuring the system.
2010-08-03Update primary bootstrapBjörn Gustavsson
2010-08-03Fix building of primary bootstrap when versions have changedBjörn Gustavsson
If the versions of kernel or stdlib have changed, attempting to update the primary bootstrap (using "./otp_build update_primary") will fail during the rebuild of the start scripts. The problem is that the app files in bootstrap/lib/*/ebin/*.app will not be refreshed if they exist, because of missing dependencies. Ultimately the dependencies should be fixed, but since there already is a bootstrap_clean target to work around missing dependencies, fix bootstrap_clean to also remove bootstrap/lib/*/ebin/*.app.

2010-07-29beam_asm: Simplify string table generation for beamsPaul Guyot
The code for generating the string table (which is now only used for bit syntax matching) in a BEAM file is quite complicated and potentially expensive when compiling modules with many thousands of clauses doing bit syntax matching. Simplify and optimize the code using bit syntax and binary:match/2 instead of the list operations in the original code.
2010-07-28Load native code for modules loaded before the code serverPaul Guyot
When configuring erlang with --enable-native-libs, some core modules are compiled with hipe, yet because they are loaded before the code server, their native code is not loaded. The fix consists in quietly trying to load the native code for all loaded modules just after the code server is started.

2010-07-07Fix ets:select hanging on ordered_set with empty list as key.Sverker Eriksson
erl_db_tree.c incorrectly used NIL (empty list) as "lastkey" to mark start of the iteration. A real NIL key could then cause a select or match iteration to be restarted over and over again if the last key before a trap happended to be NIL. Changed NIL to THE_NON_VALUE. Should be ok as the initial key value can never be put into any continuation tuple.
