If you manage to later update the MaverickCrunch patchset up to 4.5 (4.6!), we can then add it. > How would Crunch-hungry folks find out that they need so select > specific versions version of GCC to get working FPU support? First, we have to properly finish the hard/soft/softfp stuff, as it might have some implications on Crunch (but I don't really know...). Most notably, if hardware floating point is used, then ARM can offer an option for each of the available FPUs: vfp{,v2,v3}, neon, crunch... Second, in the help entry for each FPU, we can list the requirements; for example: - crunch requires: gcc in [4.2.4, 4.3.3, 4.3.4] - neon requires gcc >= 4.5 - and so on... Third, we can provide a sample with crunch enabled, so people can start off with that. Regards, Yann E.
