2010-07-07Fix a bug in the type of lists:flatmap/2.Kostis Sagonas
The code handling this BIF did not take into account that the fun in the first argument that could return [] and therefore the return value of the BIF could also be [].

2010-06-11Merge branch 'egil/eprof' into devErlang/OTP
* egil/eprof: Fix eprof to handle error cases Dialyzer cleanup for eprof Fix fprof_SUITE to use new eprof API Switch pattern API for eprof profile with mfa Update eprof documentation Update eprof_SUITE with more basic tests Rename sorting choices for eprof Teach eprof to align text output Add dump functionality to eprof Add log functionality to eprof Update eprof tests to reflect new eprof Add start timestamp to eprof profiling Teach eprof to use the new breakpoints 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).

2010-06-09Merge branch 'ks/dialyzer-R14-fixes' into devErlang/OTP
* 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.

2010-05-31Add erlang:nif_error/1,2Björn Gustavsson
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.)
2010-05-20Remove stray support for the put_literal/2 instructionBjörn Gustavsson
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.
2010-05-20Remove stray support for the bs_bits_to_bytes2/2 instructionBjörn Gustavsson
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.
2010-05-12hipe_beam_to_icode: Correct names of new recv_* instructionsKostis Sagonas
The bug was introduced in d60f055697cfe8e7f94be4d291d49bb00a66bc52.
2010-05-12Merge branch 'bg/opt-receive' into devErlang/OTP
* 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.)
2010-05-11hipe_icode: Suppress a dialyzer warningKostis Sagonas
2010-05-11Introduce the new recv_mark/1 and recv_mark/1 instructionsBjörn Gustavsson
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.
