2011-11-30Disable floating point exceptions on Mac OS X by defaultBjörn Gustavsson
Many test cases provoke printouts similar to: ERTS_FP_CHECK_INIT at 0x131fd218: detected unhandled FPE at 0x1 Until the problem has been identified and fixed, disable floating point exceptions by default on Mac OS X.

2011-11-29big_SUITE: Eliminate use of tuple funBjörn Gustavsson
It seems that a tuple fun was used only because erl_eval:expr/3 did not support passing in a real fun at the time that the test case was originally written.

2011-11-29erl_process.c: Remove the redundant variable 'processes_busy'Björn Gustavsson
There is a static variable called 'processes_busy' in erl_process.c, which will be incremented but never used. To confuse things, there is also a global variable with the same name, but it it is only defined and used if BM_COUNTERS is defined. In erl_process.c, the global version of 'processes_busy' will be seen and incremented if BM_COUNTERS is defined. Remove the static version of 'processes_busy' in erl_process.c, but keep the global version if BM_COUNTERS is defined. Noticed-by: Jovi Zhang

2011-11-26beam_load.c: Add init_iff_file() for verifying the IFF headerBjörn Gustavsson
Add init_iff_file() for verifying the IFF header. Also let it handle compressed BEAM files so that it will be done in one place. That means that code:get_chunk/2 and code:module_md5/1 will now support compressed BEAM files.
2011-11-26beam_code.c: Don't reinvent state initialization and deallocationBjörn Gustavsson
2011-11-26beam_load.c: Optimize code:get_chunk/2Björn Gustavsson
The undocumented code:get_chunk/2 BIF is supposed to be a fast way to extract a chunk from a BEAM file when loading native code. In practice, it might not have been faster because it happened to calculate an MD5 checksum for the chunk it extracted because it shared the scan_iff_file() function with the erlang:load_module/2 BIF. Split scan_iff_file() into scan_iff_file() and verify_chunks(), so that the unnecessary MD5 calculation can be avoided.
2011-11-26beam_load.c: Eliminate memory leak in code:make_stub_module/3Björn Gustavsson
code:make_stub_module/3 leaked memory if given either a corrupt BEAM file, or a compressed BEAM file and an error occurred, or a binary not aligned on byte boundaries.
2011-11-25erlc_SUITE:arg_overflow/1: Lower number of options for MacOS X LionBjörn Gustavsson
On my Mac, the highest successful value was 7673. The new value provides some safety margin.
2011-11-25Fix clang linking problemBjörn Gustavsson
Inlining was not done in a portable way. clang follows the C99 semantics for inlining ('inline' essentially implies 'static' in C99, but not in GCC), so bp_sched2ix() was not visible outside beam_bp.c. Since the function need to be used from more than one source file, put the function definition in the beam_bp.h header file. Also, give it an 'erts_' prefix since it is globally visible.
2011-11-25configure: Define NO_JUMP_TABLE if all we have is llvm-gccBjörn Gustavsson
Commit dd24ca1cb76d attempts to fix the problem that LLVM-based compilers (such as llvm-gcc-4.2 and clang) miscompiles beam_emu.c. The idea was to force the use of gcc-4.2 if the default compiler was LLVM-based. Since that fix, Apple released Xcode 4.2 that does not include any version of gcc, only llvm-gcc-4.2 and clang. We could require gcc in order to be the system, but it would be nice if Erlang/OTP could be built out-of-box on MacOS X, albeit with reduced performance. Therefore, make sure that we set NO_JUMP_TABLE (use a switch statement instead of computed gotos in beam_emu.c) if no compiler that correctly handles computed gotos can be found. We know that clang based on the upcoming LLVM 3.0 will work, but older LLVM-based compilers will not, so we can test the version of clang. llvm-gcc has been discontinued in LLVM 3.0, so if the compiler is LLVM-based but not clang, we can assume that it does not handles computed gotos correctly.

2011-11-25beam_emu.c: Use the correct void* type for computed gotosBjörn Gustavsson
gcc don't care about the type, but clang does and will issue a warning.
2011-11-25MacOS X: Completely remove obsolete -no-cpp-precomp optionBjörn Gustavsson
clang does not recognize the -no-cpp-precomp option and generates a warning. -no-cpp-precomp is an obsolete Apple-specific gcc option, which last had any effect in gcc 3.1 for Jaguar. Since we cannot build for Jaguar anyway, the configure test added in 8412a400e92d5cbcd is not needed.

2011-11-18Use unbound schedulers as defaultRickard Green
As of ERTS version 5.9 (OTP-R15B) the runtime system will by default not bind schedulers to logical processors. If the Erlang runtime system is the only operating system process that binds threads to logical processors, this improves the performance of the runtime system. However, if other operating system processes (as for example another Erlang runtime system) also bind threads to logical processors, there might be a performance penalty instead. In some cases this performance penalty might be severe. Due to this, we change the default so that the user must make an active decision in order to bind schedulers.
