oon3m0oo a399d00425 Further improvements to memory.c. (#1625) 
- Compiler TLS is now used only used when the compiler supports it
- If compiler TLS is unsupported, we use platform-specific TLS
- Only one variable (an index) is now in TLS
- We only access TLS once per alloc, and never when freeing
- Allocation / release info is now stored within the allocation itself, by
  over-allocating; this saves having external structures do the bookkeeping, and
  reduces some of the redundant data that was being stored (such as addresses)
- We never hit the alloc lock when not using SMP or when using OpenMP (that was
  my fault)
- Now that there are fewer tracking structures I think this is a bit easier to
  read than before

Arjan van de Ven 2ddc96c9e5 make WMB / MB safer on x86-64 
make it so that

if (foo)
	RMB;
else
	MB;

is always done correctly and without syntax surprises
 2018-06-17 18:06:24 +00:00
Arjan van de Ven 7e39ffe113 On x86-64, make MB/WMB compiler barriers 
Whie on x86(64) one does not normally need full memory barriers, it's
good practice to at least use compiler barriers for places where on other
architectures memory barriers are used; this prevents the compiler
from over-optimizing.
 2018-06-17 17:53:15 +00:00
Arjan van de Ven 73de17664d Add missing barriers in gemm scheduler 
a few places in the gemm scheduler code were missing barriers;
the code likely worked OK due to heavy use of volatile / _Atomic
but there's no reason to get this incorrect
