Thus far, GCC has been just fine other than violating some behavioral expectations that were never guaranteed (the linker sets patches). Newlib has some ILP32 issues that need to be addressed. I've gotten a patch into the upstream ARM optimized routines that will eventually make it into Newlib and fix those issues. There's possibly another issue with the "dc zva" instruction that may also be solved by enabling the MMU.

I hope this is not common and tools like gcc etc are more supportive of ILP32.
