I'm trying to see how the x86 backend deals with the relationship between AL, AH and AX, but I can't get it to generate any code that would expose an interesting scenario. For example, I wrote this piece: typedef struct { char x, y; } struct_t; struct_t z; struct_t foo(char *p) { struct_t s; s.x = *p++; s.y = *p; z = s; s.x++; return s; } But the output at -O2 is foo: # @foo .cfi_startproc # BB#0: # %entry movb (%rdi), %al...
