* lukas/erts/non-blocking-shell: erts: Fix big-endian issue with printf_putc
2014-12-15erts: Fix big-endian issue with printf_putcLukas Larsson
On little-endian machines, doing &int will give the smallest byte which is what we want to give to write. But on big-endian it will give the highest byte, which will always be \000 here which results in write never doing any writes. So we have to cast c to an unsigned char before passing it to write.

2014-11-04erts: Make erts_printf work with non-blockingLukas Larsson
Now that stdout can be set as non-blocking by the ttsl driver we can no longer use putc and friends for the stdout/stderr streams. Therefore we fallback on write. OTP-12239
2014-10-19Fix bug in FreeBSD topology detection codePaul Guyot
Code incorrectly relied on undefined C behavior. Clang and gcc 4.9 do not behave as code expected. This affected cores and processors detection on FreeBSD.

2014-02-28Add ETHR_FORCE_INLINE define to hide compiler specific directivesJani Hakala
Some win32 specific code does not compile with gcc (mingw-w64) since '__forceinline' is not supported by gcc. This can be avoided by defining a new macro ETHR_FORCE_INLINE similar to ETHR_INLINE.

This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers.

On architectures where cpu topology was unavailable, warnings erupted due to unused static functions. Those warnings are now silenced.

2012-03-15erts: Fix memory corruption when reading topology infoSverker Eriksson
If the number of processors actually found while reading sysfs is lower than the configured value, we realloc() the cpuinfo array to the smaller size, but we then iterate it using the original configured size, thus corrupting memory beyond the allocated block.

2011-06-14Improve ethread atomicsRickard Green
The ethread atomics API now also provide double word size atomics. Double word size atomics are implemented using native atomic instructions on x86 (when the cmpxchg8b instruction is available) and on x86_64 (when the cmpxchg16b instruction is available). On other hardware where 32-bit atomics or word size atomics are available, an optimized fallback is used; otherwise, a spinlock, or a mutex based fallback is used. The ethread library now performs runtime tests for presence of hardware features, such as for example SSE2 instructions, instead of requiring this to be determined at compile time. There are now functions implementing each atomic operation with the following implied memory barrier semantics: none, read, write, acquire, release, and full. Some of the operation-barrier combinations aren't especially useful. But instead of filtering useful ones out, and potentially miss a useful one, we implement them all. A much smaller set of functionality for native atomics are required to be implemented than before. More or less only cmpxchg and a membar macro are required to be implemented for each atomic size. Other functions will automatically be constructed from these. It is, of course, often wise to implement more that this if possible from a performance perspective.
