Description

This ticket sets PJ_HAS_FLOATING_POINT to 1 in config_site_sample.h. Both armv6 and armv7 support single and double precision floating point in hardware.

  • The armv6 is in original iPod, iPod touch second gen, original iPhone and iPhone 3G
  • The armv7 is in iPhone 3GS and up, original iPad and up

You need to disable Thumb code generation for armv6 for faster FP operations, according to ​this and ​this discussions.

Thanks Kees van der Bent for the note.
