I'm trying to write a store pattern that accepts both i32 and f32, however, when tablegen generates the code, it only generates the code for i32 only. def ADDR : ComplexPattern<i32, 2, "SelectADDR", [], []>; def MEM : Operand<i32> { let PrintMethod = "printMemOperand"; let MIOperandInfo = (ops GPR, GPR); } def global_st :

...erns me about __builtin_assume_aligned and this scheme is the control dependencies. In gcc, it is the return value of the intrinsic that carries the alignment guarantee, and I think that this makes a lot of sense. Consider something like this: void foo(double *x) { if (check_if_x_is_special(&global_state)) { y = __builtin_assume_aligned(x, 16); do_something(y); } else do_something_else(x); } with this scheme, there is never a danger that the alignment assumption can be lifted and incorrectly applied to x in an inlined do_something_else(x). If we simply have the intrinsic not return a...

v1 -> v2: The first patch is the same (the pure refactoring), but in the second patch I implement Eric Blake's suggested version. Rich.

The NULL initialization of the pointers assigned by kzalloc() or kunit_kzalloc() first is not necessary, because if the kzalloc() or kunit_kzalloc() failed, the pointers will be assigned NULL, otherwise it works as usual. so remove it.
