double halide_float16_bits_to_double(uint16_t)
Read bits representing a half precision floating point number and return the double that represents t...
int halide_msan_annotate_memory_is_initialized(void *user_context, const void *ptr, uint64_t len)
Annotate that a given range of memory has been initialized; only used when Target::MSAN is enabled.
void halide_print(void *user_context, const char *)
Print a message to stderr.
void halide_error(void *user_context, const char *)
Halide calls this function on runtime errors (for example bounds checking failures).

@ Internal
Not visible externally, similar to 'static' linkage in C.
std::ostream & operator<<(std::ostream &stream, const Expr &)
Emit an expression on an output stream (such as std::cout) in human-readable form.
Expr print(const std::vector< Expr > &values)
Create an Expr that prints out its value whenever it is evaluated.
