iPhone libgcc?

I was looking at Gruber’s iPhone crash log… and came across:

0×31c38000 - 0×31c3ffff libgcc_s_v6.1.dylib UUID (C3CE0B41C9CA490EAEADA6D7EB997082) /usr/lib/libgcc_s_v6.1.dylib

Does that mean the iPhone’s OS X 1.0 is shipping with GCC?

Also interesting:

0×31db9000 - 0×31dbcfff liblockdown.dylib UUID (30A0EB0C05724FA487617B860E360B88) /usr/lib/liblockdown.dylib

Hmmmm…

Another:

0×3026d000 - 0×3032cfff Celestial UUID (15045615F83249D49720253EBDF9132A) /System/Library/Frameworks/Celestial.framework/Celestial

What is the Celestial framework?

This doesn’t mean GCC is packaged on all the iPhones, which would be extremely unlikely. All code compiled with gcc requires libgcc_s.

Daniel: I considered that but I wasn’t sure, I ran a locate for libgcc_s and completely missed the /usr/lib/ results. I thought they were only in /Developer/SDKs/.

Thanks for clearing that up!
