Constructor & Destructor Documentation

◆ CodeGen_Posix()

Halide::Internal::CodeGen_Posix::CodeGen_Posix ( Target  t)

Create an posix code generator.

Processor features can be enabled using the appropriate arguments

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.

Reimplemented in Halide::Internal::CodeGen_Hexagon.

Referenced by Halide::Internal::CodeGen_Hexagon::allocation_padding().

◆ 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.

Reimplemented from Halide::Internal::CodeGen_LLVM.

◆ visit() [3/94]

void Halide::Internal::CodeGen_LLVM::visit
overrideprotected

Generate code for various IR nodes.

These can be overridden by architecture-specific code to perform peephole optimizations. The result of each is stored in value

Generate code for an allocate node.

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

These IR nodes should have been removed during lowering.

CodeGen_LLVM will error out if they are present
