How can I identify if my CPU is using 32-bit or 64-bit instruction set? On a Linux systems this question can be easily answered by running a command: cat /proc/cpuinfo. what we are interest in here is a flags row which indicates a CPU’s capabilities / features.

Introduction Since Mac OSX is derived from BSD sources, I wrongly presumed the BSD codes would work without problem. 0x4d_ having a Mac was able to confirm they did not work and so we realized quickly the solution was simply setting bit 25 of EAX register using BTS instruction (Bit Test and Set). ; bts
This is even more important in conjunction with _Atomic. Note the code as posted cannot be optimized to use bts, since the BitOffset operand is signed.
Using critical section and mutex related articles have been done to death, here we try a unique approach to understand the test and set x86-32 bit instruction for implementing critical sections (Spin lock part only). Critical sections (CS) are used in all modern programming paradigms where

Bit and Byte Instructions. The bit instructions test and modify individual bits in operands. The byte instructions set the value of a byte operand to indicate the status of flags in the %eflags register.. Table 3-6 Bit and Byte Instructions
