- Restricted Transactional Memory Overview
- _xtest
Queries whether the processor is executing in a transactional region identified by restricted transactional memory (RTM) or hardware lock elision (HLE). The corresponding Intel® AVX2 instruction is XTEST.
- _xbegin
Specifies the start of a restricted transactional memory (RTM) code region and returns a value indicating status. The corresponding Intel® AVX2 instruction is XBEGIN.
- _xend
Specifies the end of a restricted transactional memory (RTM) code region. The corresponding Intel® AVX2 instruction is XEND.
- _xabort
Forces a restricted transactional memory (RTM) region to abort. The corresponding Intel® AVX2 instruction is XABORT.
