Public Attributes
mlir::Operation *	op = nullptr
	The allocation operation (fir.alloca or fir.allocmem).
bool	isCurrentlyOnStack = false
	True if the allocation currently lives on the stack (fir.alloca).

std::optional< std::int64_t >	byteSize
	The constant size of the allocation in bytes, if it can be determined.

Detailed Description

Facts about a single array allocation used to decide its placement.

Member Data Documentation

isDynamic

bool fir::AllocationInfo::isDynamic = false

True if the allocation has a runtime-determined size. Note this is not the same as !byteSize: a constant-size array may have no computable byteSize (e.g. when no data layout is available), in which case it is not dynamic but its size is still unknown.

isTemporary

bool fir::AllocationInfo::isTemporary = false

True if the allocation is a compiler temporary (as opposed to a user variable).
