Martin Stein b04a70177b base & arm: simplify and optimize cmpxchg ... The old inline assembly provided two output operands that were afterwards combined for a return value. However, the second output operand isn't necessary when using the "Acquiring a Lock" example-code of the ARM manual "Barrier Litmus Tests and Cookbook". This saves two logical operations per acquisition try. Additionally better documentation is now provided. Fixes #1292		2019-04-01 19:33:47 +02:00
