Enumerations
enum class	pulp::signal::FftBackend {   pulp::signal::auto_ , pulp::signal::vdsp , pulp::signal::kissfft , pulp::signal::fftw3 ,   pulp::signal::mkl }

Functions
const char *	pulp::signal::fft_backend_name (FftBackend b) noexcept
	Stringify a backend tag for diagnostics / env-var parsing.
FftBackend	pulp::signal::parse_fft_backend (const char *s) noexcept
	Parse a backend tag from a string. Unknown / empty → auto_.
bool	pulp::signal::fft_backend_available (FftBackend b) noexcept
	True iff the backend can be instantiated on this machine right now.
FftBackend	pulp::signal::resolve_fft_backend (FftBackend hint=FftBackend::auto_) noexcept
	Resolve auto_ → best available backend on this machine, honoring the PULP_FFT_BACKEND env var if set to a concrete backend that is available.
