2011-09-27distribution_SUITE: Use unique slave node namesBjörn Gustavsson
bad_dist_ext_connection_id/1 used the same names for the slave nodes as bad_dist_ext_receive/1, which would cause it to fail if bad_dist_ext_receive/1 failed.
2011-09-26busy_port_SUITE: Avoid crash in register/2Björn Gustavsson
Add an end_per_testcase/2 function to ensure that the process with the name 'busy_drv_server' has been killed before the next test case attempts to register a process with the same name.

* rickard/aux-work-bug/OTP-9567: Fix lost wakeup of scheduler when enqueuing auxiliary work
2011-09-22Fix lost wakeup of scheduler when enqueuing auxiliary workRickard Green
When auxiliary work was enqueued on a scheduler, the wakeup of the scheduler in order to handle this work could be lost. Wakeups in order to handle ordinary work were not effected by this bug. The bug only effected runtime systems with SMP support as follows: * Deallocation of some ETS data structures could be delayed. * On Linux systems not using the NPTL thread library (typically ancient systems with kernel versions prior to 2.6) and Windows systems, the {Port, {exit_status, Status}} message from a terminating port program could be delayed. That is, it only effected port programs which had been started by passing exit_status as an option to open_port/2.

* bjorn/erts/support-macosx-lion/OTP-9547: Fix build problems on MacOS 10.7 (Lion)
2011-09-20Fix build problems on MacOS 10.7 (Lion)Björn Gustavsson
On MacOS 10.7 (Lion) with Xcode 4.1 installed, the default C compiler is llvm-gcc-4.2. That compiler compiles beam_emu.c incorrectly, resulting in an emulator that will not start. The problem can be worked around by turning off all optimizations, but that will significantly degrade the performance of the run-time system. The problem can also be worked around manually like this: CC=gcc-4.2 ./configure To allow a working system to be built "out of the box", have the configure script set up the emulator Makefile so that gcc-4.2 will be used to compile beam_emu.c if the default compiler is llvm-based. All other C files will still be compiled with the default compiler.

2011-09-06BEAM: Unify allocation of X and float registersBjörn Gustavsson
In the half-word emulator, smp emulator, and non-smp emulator the X register and float register arrays were allocated in different ways. Always allocate the registers and store the pointers to the allocated register arrays in the scheduler data.
2011-09-02Fix enif_compare on 64bits machinesFilipe David Manana
In 64bits machines the Sint type has a size of 8 bytes, while on 32bits machines it has a 4 bytes size. enif_compare was ignoring this and therefore returning incorrect values when the result of the CMP function (which returns a Sint value) doesn't fit in 4 bytes. For example, passing the operands -1294536544000 and -1178704800000 to enif_compare would trigger the bug.

This BIF's second parameter is a list of options. Currently the only allowed option is {minor_version, Version} where version is either 0 (default) or 1.

2011-08-25Add erlang:check_old_code/1Björn Gustavsson
Add erlang:check_old_code/1 to quickly check whether a module has old code. If there is no old code, there is no need to call erlang:check_process_code/2 for all processes, which will save some time if there are many processes.
2011-08-25check_process_code/2: Quickly return 'false' if there is no old codeBjörn Gustavsson
There is no need to suspend the process if the module has no old code. Measurements show that this change will make erlang:check_process_code/2 in an SMP emulator about four times faster if the module has no old code.
