<pre>Consider this:
typedef struct foo {
float a;
double b;
} foo;
int main() {
foo x;
__asm {lea eax, x
};
}
microsoft allows the following syntaxes for structures:
fstp foo[eax].b (evaluates it to be eax+b_offset)
fstp x[eax].b (evaluates it to be x+eax+b_offset)
fstp x.b[eax] (evaluates it to be eax+b_offset)
fstp foo.b[eax] (evaluates it to be eax+b_offset)
fstp [eax].b (as long as b isn't ambiguous)
while llvm only accepts (ms also accept these):
fstp [eax]x.b (evaluates it to be eax+b_offset)
fstp [eax]foo.b (evaluates it to be eax+b_offset)</pre>
