Detailed Description

template<int SLMAmount>
class sycl::_V1::ext::intel::esimd::slm_allocator< SLMAmount >

RAII-style class used to implement "semi-dynamic" SLM allocation.

SLM is allocated in the constructor and released in the destructor, that's why it is "dynamic", as opposed to fully static allocation style of 'slm_init'. Actual offset of SLM chunk allocated by the call is calculated at compile time, that's why it is "semi-". To calculate SLM usage by a kernel, compiler finds a path in a callgraph with the largest amount of SLM "locked" by slm_allocator objects live along the paths. slm_init call also participates in calculating SLM budget. It can be modelled as slm_allocator object declared at the very beginning of a kernel and live till its the very end. Only compile-time constant SLM amount is supported for now, it is provided as a class' template argument.

Since a call graph is used, function pointers and recursion is not supported.
