2013-01-15Implement ./otp_build configure --enable-silent-rulesAnthony Ramine
With silent rules, the output of make is less verbose and compilation warnings are easier to spot. Silent rules are disabled by default and can be disabled or enabled at will by make V=0 and make V=1.
2012-10-10erts: Fix '#ifdef' for unused static functionsBjörn-Egil Dahlberg
On architectures where cpu topology was unavailable, warnings erupted due to unused static functions. Those warnings are now silenced.

Add probes to the virtual machine, except (mostly) the efile_drv.c driver and other file I/O-related source files.
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.

2011-12-27Fix lwsync instruction feature testRickard Green
A feature test for the lwsync instruction performed on PowerPC hardware at runtime system startup got into an eternal loop if the instruction was not supported. This bug was introduced in erts-5.9/OTP-R15B.

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.
