Bug ID: 32432
Summary: [inline asm] structure with imm prefixes generate
wrong asm
Product: new-bugs
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P

typedef struct foo {
float a;
double b;
} foo;
int main() {
foo x;
__asm {lea eax, x
fstp dword ptr 2[eax]foo.b
};
}
Instead of generating fstp [eax + 0x0a] -> 2(imm) + 8(offset) we get 0x0c.
generally : a[eax]foo.b gives 2*a + offset(foo.b).
