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.

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.

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.
|
|
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.

On my Mac, the highest successful value was 7673. The new value
provides some safety margin.

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.

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.

gcc don't care about the type, but clang does and will issue
a warning.
|
|
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.

This suppresses the 'missing_sasl' warning from systools.

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.

The spinlocks used implementing pix-locks have been replaced with
mutexes since they perform better during heavy contention.

It is better that gen_sctp:open/0-2 returns the informative Posix
return code {error,eprotonosupport} than previously {error,badarg}
when SCTP is not supported since it is so platform dependent.

No semantic change, just code clarification.
Use unique macro names instead of redefining the original ones.
|
|
On e.g FreeBSD the functions sctp_bindx() and sctp_peeloff() do not require
any extra linkage library flags and there is no dynamic lib to load
for them; use configure to find them.

Receive several fragments within the same receive loop if possible.
