OTP-8706 egil/eprof
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).

* ks/dialyzer-R14-fixes:
Various changes to dialyzer-related files for R14.
OTP-8699 ks/dialyzer-R14-fixes
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.

* commit 'bg/nif_error':
crypto: Add type specs for all documented functions
crypto: Use erlang:nif_error/1 to squelch false Dialyzer warnings
Add erlang:nif_error/1,2
|
|
erlang:garbage_collect_message_area/0 is undocumented and unsupported.
|
|
|
|
(erlang:port_call/2 is undocumented.)
|
|
|
|
|
|
|
|
|
|
These are aliases for '++'/2 and '--'/2.
|
|
While at it, introduce a new type for adler32 and crc32
and use it consistently within the file.
|
|
|
|
It is useful for testing.
|
|

A stub function that is supposed to be replaced by a NIF usually
calls erlang:error/1 to cause an exception if the NIF library
is not loaded. For example:
foo() ->
erlang:error(nif_not_loaded).
The problem is that although erlang:error/1 will normally never be
called, Dialyzer will think that any call to the function will fail
and thus generate false warnings. Adding a spec for the function
will not help because Dialyzer will not believe the spec.
Add erlang:nif_error/1,2 that work exactly like erlang:error/1,2.
Define the return types for both BIFs to be t_any().
erlang:nif_error is used like this:
-spec foo() -> binary().
foo() ->
erlang:nif_error(nif_not_loaded).
(The -spec is optional but highly recommended, since Dialyzer
otherwise has no chance to figure out the types.)

put_literal/2 was an experimental instruction added in R11 to
support literals, but before the R12 release support for literals
was implemented for all instruction, making the put_literal/2
instruction redundant. Although the beam_disasm module supports
dissambley of instructions in older releases, there is
no reason to have it support experimental instructions.
|
|
bs_bits_to_bytes2/2 was an experimental instruction added in R11,
but was removed in R12. Although the beam_disasm and beam_validator
modules do support instructions in older releases, there is
no reason to have them support experimental instructions.
|
|
The bug was introduced in d60f055697cfe8e7f94be4d291d49bb00a66bc52.

* bg/opt-receive:
Test that gen_server:call/2,3 are fast even with a huge message queue
erts: Add tests for the receive optimization
Update primary bootstrap
erts: Implement recv_mark/1 and recv_set/1 for real
compiler tests: Cover the error handling code in beam_receive
compiler test: Test optimization of receive statements
Optimize selective receives in the presence of a large message queue
Introduce the new recv_mark/1 and recv_mark/1 instructions
Compile tests that communicate with R12 nodes with the r12 option
Move p_run/2 to test_lib
gen: Inline wait_resp_mon/2 to help the compiler optimize
OTP-8623 bg/opt-receive
reveive 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.)
|
|
|
|
Make the recv_mark/1 and recv_mark/1 instructions known to the
compiler and run-time system. For the moment, make the loader ignore
any occurrences of those instructions in BEAM files.
Also update hipe_beam_to_icode to ignore those instructions.
|
|
|
|
When defining macros the closing right parenthesis before the dot is now
mandatory.
|
|
* jb/pp_arm-imm-fix:

|
|
Improve readability by decoding imm8m constants before printing them.

* bg/erl_bif_types:
Add types for erts_debug:lock_counters/1
Add types for os:timestamp/0
Add types for erts_debug:dist_ext_to_term/2
erl_bif_types: add 'http_bin' as a valid packet option
OTP-8437: bg/erl_bif_types
|
|
erts_debug:lock_counters/1 is an undocumented BIF used by
the 'lcnt' module in the 'tools' application.
|
|
|
|
|
|
{packet,http_bin} is now a valid packet option for the
gen_tcp and inet modules.

environment after a number of bugs are fixed and some features
are added in the documentation build process.
- The arity calculation is updated.
- The module prefix used in the function names for bif's are
removed in the generated links so the links will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-
2".
- Enhanced the menu positioning in the html documentation when a
new page is loaded.
- A number of corrections in the generation of man pages (thanks
to Sergei Golovan)
- The legal notice is taken from the xml book file so OTP's build
process can be used for non OTP applications.

improvements.
Most notable:
Lots of cross compilation improvements. The old cross compilation
support was more or less non-existing as well as broken. Please,
note that the cross compilation support should still be
considered as experimental. Also note that old cross compilation
configurations cannot be used without modifications. For more
information on cross compiling Erlang/OTP see the
$ERL_TOP/xcomp/README file.
Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D
ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed.
For more information see the $ERL_TOP/README file.
Documentation of the release target of the top Makefile. For more
information see the $ERL_TOP/README file.
make install now by default creates relative symbolic links
instead of absolute ones. For more information see the
$ERL_TOP/README file.
$ERL_TOP/configure --help=recursive now works and prints help for
all applications with configure scripts.
Doing make install, or make release directly after make all no
longer triggers miscellaneous rebuilds.
Existing bootstrap system is now used when doing make install, or
make release without a preceding make all.
The crypto and ssl applications use the same runtime library path
when dynamically linking against libssl.so and libcrypto.so. The
runtime library search path has also been extended.
The configure scripts of erl_interface and odbc now search for
thread libraries and thread library quirks the same way as erts
do.
The configure script of the odbc application now also looks for
odbc libraries in lib64 and lib/64 directories when building on a
64-bit system.
The config.h.in file in the erl_interface application is now
automatically generated in instead of statically updated which
reduces the risk of configure tests without any effect.
