mesa: use fi_type in vertex attribute code
For 32-bit builds, floating point operations use x86 FPU registers, not SSE registers. If we're actually storing an integer in a float variable, the value might get modified when written to memory. This patch changes the VBO code to use the fi_type (float/int union) to store/copy vertex attributes. Also, this can improve performance on x86 because moving floats with integer registers instead of FP registers is faster. Neil Roberts review: - include changes on all places that are storing attribute values. - check with and without -O3 compiler flag. Brian Paul review: - use fi_type type instead gl_constant_value type - fix a bunch of nit-picks. - fix compiler warnings Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=82668 Signed-off-by: Marius Predut <[email protected]> Reviewed-by: Brian Paul <[email protected]>
