Member Function Documentation

◆ visit() [1/94]

void Halide::Internal::CodeGen_Posix::visit ( const Allocate * )

overrideprotectedvirtual

Posix implementation of Allocate.

Small constant-sized allocations go on the stack. The rest go on the heap by calling "halide_malloc" and "halide_free" in the standard library.

Implements Halide::Internal::CodeGen_LLVM.

◆ visit() [2/94]

void Halide::Internal::CodeGen_Posix::visit ( const Free * )

overrideprotectedvirtual

Generate code for a free node.

It has no default implementation and must be handled in an architecture-specific way.

Implements Halide::Internal::CodeGen_LLVM.

◆ allocation_padding()

virtual int Halide::Internal::CodeGen_Posix::allocation_padding ( Type type ) const

protectedvirtual

It can be convenient for backends to assume there is extra padding beyond the end of a buffer to enable faster loads/stores.

This function gets the padding required by the implementing target.

◆ get_allocation_name()

std::string Halide::Internal::CodeGen_Posix::get_allocation_name ( const std::string & n )

overrideprotectedvirtual

Get a unique name for the actual block of memory that an allocate node uses.

Used so that alias analysis understands when multiple Allocate nodes shared the same memory.
