 halide_abort_if_false() is a macro that calls halide_print if the supplied condition is false, then aborts.
 
#define _halide_expand_and_stringify(x)
 
#define halide_abort_if_false(user_context, cond)

 halide_debug_assert() is like halide_assert(), but only expands into a check when DEBUG_RUNTIME is defined.

◆ _halide_stringify

#define _halide_stringify ( x)
Value:

halide_abort_if_false() is a macro that calls halide_print if the supplied condition is false, then aborts.

Used for unrecoverable errors, or should-never-happen errors.

Note that this is NOT a debug-only macro; the condition will be checked in all build modes!

◆ halide_debug_assert

#define halide_debug_assert ( user_context,
cond )

halide_debug_assert() is like halide_assert(), but only expands into a check when DEBUG_RUNTIME is defined.

It is what you want to use in almost all cases.
