[Bug target/17103] Opportunity to replace multiply with shift/add sequence

[dje at gcc dot gnu dot org]

------- Additional Comments From dje at gcc dot gnu dot org  2004-09-12 20:37 -------
On POWER4, the default processor, the latency of mulli relative to shifts and
adds makes mulli a better choice than synthesizing the multiply by constant. 
When tuning for other PowerPC processors, such as POWER3, the synthesized
sequence is generated.
