This file defines the class FunctionDAG, which is our representation of a Halide pipeline, and contains methods to using Halide's bounds tools to query properties of it. | |

Functions | |
llvm::Type * | Halide::Internal::get_vector_element_type (llvm::Type *) |
Get the scalar type of an llvm vector type. | |
bool | Halide::Internal::function_takes_user_context (const std::string &name) |
Which built-in functions require a user-context first argument? | |
bool | Halide::Internal::can_allocation_fit_on_stack (int64_t size) |
Given a size (in bytes), return True if the allocation size can fit on the stack; otherwise, return False. | |
std::pair< Expr, Expr > | Halide::Internal::long_div_mod_round_to_zero (const Expr &a, const Expr &b, const uint64_t *max_abs=nullptr) |
Does a {div/mod}_round_to_zero using binary long division for int/uint. | |
Expr | Halide::Internal::lower_mux (const Call *mux) |
Reduce a mux intrinsic to a select tree. | |
Expr | Halide::Internal::lower_round_to_nearest_ties_to_even (const Expr &) |
An vectorizable implementation of Halide::round that doesn't depend on any standard library being present. | |
void | Halide::Internal::get_target_options (const llvm::Module &module, llvm::TargetOptions &options) |
Given an llvm::Module, set llvm:TargetOptions information. | |
void | Halide::Internal::clone_target_options (const llvm::Module &from, llvm::Module &to) |
Given two llvm::Modules, clone target options from one to the other. | |
std::unique_ptr< llvm::TargetMachine > | Halide::Internal::make_target_machine (const llvm::Module &module) |
Given an llvm::Module, get or create an llvm:TargetMachine. | |
void | Halide::Internal::set_function_attributes_from_halide_target_options (llvm::Function &) |
Set the appropriate llvm Function attributes given the Halide Target. | |
void | Halide::Internal::embed_bitcode (llvm::Module *M, const std::string &halide_command) |
Save a copy of the llvm IR currently represented by the module as data in the __LLVM,__bitcode section. | |
Expr | Halide::Internal::lower_int_uint_div (const Expr &a, const Expr &b, bool round_to_zero=false) |
Given a Halide Euclidean division/mod operation, do constant optimizations and possibly call lower_euclidean_div/lower_euclidean_mod if necessary. | |
Expr | Halide::Internal::lower_int_uint_mod (const Expr &a, const Expr &b) |
Given a Halide Euclidean division/mod operation, do constant optimizations and possibly call lower_euclidean_div/lower_euclidean_mod if necessary. | |
Expr | Halide::Internal::lower_euclidean_div (Expr a, Expr b) |
Given a Halide Euclidean division/mod operation, define it in terms of div_round_to_zero or mod_round_to_zero. | |
Expr | Halide::Internal::lower_euclidean_mod (Expr a, Expr b) |
Given a Halide Euclidean division/mod operation, define it in terms of div_round_to_zero or mod_round_to_zero. | |
Expr | Halide::Internal::lower_signed_shift_left (const Expr &a, const Expr &b) |
Given a Halide shift operation with a signed shift amount (may be negative), define an equivalent expression using only shifts by unsigned amounts. | |
Expr | Halide::Internal::lower_signed_shift_right (const Expr &a, const Expr &b) |
Given a Halide shift operation with a signed shift amount (may be negative), define an equivalent expression using only shifts by unsigned amounts. | |
Expr | Halide::Internal::lower_extract_bits (const Call *c) |
Reduce bit extraction and concatenation to bit ops. | |
Expr | Halide::Internal::lower_concat_bits (const Call *c) |
Reduce bit extraction and concatenation to bit ops. | |
Defines functionality that's useful to multiple target-specific CodeGen paths, but shouldn't live in CodeGen_LLVM.h (because that's the front-end-facing interface to CodeGen).
