[Bug middle-end/37846] New: Option -mno-fused-madd should be supported on IA-64

[vincent at vinc17 dot org]

Option -mno-fused-madd is currently not supported on IA-64. This means that the
expression x*y+z is always fused (IA-64's fma instruction) and this cannot be
disabled, unlike on PowerPC.

BTW, I wonder why this option exists for PowerPC (and other CPU types) but not
for IA-64. Isn't it similar, or is there some difficulty?
