I am writing an application in C in GCC (for Linux/Ubuntu) that uses the following inline assembly.
float a[4] = { 10, 20, 30, 40 };
float b[4] = { 0.1, 0.1, 0.1, 0.1 };
asm volatile("movups (%0), %%xmm0\n\t"
"mulps (%1), %%xmm0\n\t"
"movups %%xmm0, (%1)"
:: "r" (a), "r" (b));
Excuse typos in the above (I'm writing from memory). What is the equivalent inline assembler in Visual C++ 6.0 ? I have discovered that I need to port my code.
__declspec(align(16)) float a[4] = { 10, 20, 30, 40 };
__declspec(align(16)) float b[4] = { 0.1f, 0.1f, 0.1f, 0.1f };
__asm {
movups xmm0, a; // could be movaps if array aligned
mulps xmm0, b;
movups b, xmm0; // could be movaps if array aligned
}
I'm not sure about Visual C++ 6, but it will work in Visual C++ 2008.
