Basic c++ code to SSE ... issue

[jiiteepee]

I have few lines of code giving headache when trying to port to SIMD coding:

n -= (a < 0);
n += 1023;
u.s[3] = (unsigned short)((n << 4) & 0x7FF0);

where


ieee754 u;


and


__m128i n;

__m128d a;



I could leave those working as above but would like to port if possible.

Any help is appreciated.
