This bug is -mtune (Instruction Scheduling) does not include Intel processors. It was filed on 2006-04-28 at 00:35 PDT.
With the move to Intel processors, Xcode needs to support processor-specific optimization for them.
Steps to Reproduce:
- Get info on a target or project.
- Switch to the Build tab.
- Change the active Collection to one that includes GCC/Code Generation.
- Edit the "Instruction Scheduling" setting.
At least pentium-m is listed, being (presumably) the most similar to Yonah (the "Core Solo"/"Core Duo" processors). Ideally, scheduling optimizations for Yonah itself should be added to GCC, with a matching listing in Xcode's pop-up menu.
Only G3, G4, and G5 are listed (besides "None").
This wasn't a problem before the move to Intel.
