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.

2011-11-23Avoid slow code loading of BEAM code in a hipe-enabled emulatorBjörn Gustavsson
On my Linux computer, building the entire Erlang/OTP system with hipe disabled took about 8 minutes. With hipe enabled, but without any native code, the build took about 23 minutes, i.e. more than 3 times slower. (The computer has 4 cores, and I used 'make -j6'.) On my eight-core Mac (running 'make -j10') there was only a slight slowdown when hipe was enabled. The culprit is hipe_unified_loader:post_beam_load/1, which will be called every time a module is loaded (even if the module contains no native code). If post_beam_load/1 is called in a hipe-enabled emulator, it will block multi-scheduling, even if no work needs to be done. Apparently the cost for blocking multi-scheduling can vary greatly, depending on the operating system and system load. As a quick and conservative fix, don't call post_beam_load/1 unless some native code has been previously loaded.
2011-11-23Fix release_handler:upgrade_app and downgrade_app when upgrading emulatorSiri Hansen
Changes to the mechanism for upgrading the emulator in OTP R15 was erronously not handled in release_handler:upgrade_app, downgrade_app, upgrade_script and downgrade_script. This has been corrected, including test and documentation.
