...dency on the target environment's libc implementation. I think that expanding the responsibility of compiler-rt from supporting the code generation from the compiler to integrating into the target environment's libc can be problematic. > I think we should return zero on both idiv0 and ldiv0 and move the > "mov r0, #0" inside the #else for now. > Why 0 and not infinity?

...entionally so that third-party could provide custom handler for division by zero. IMHO It's not very consistent and looks odd as all other __aebi_* functions are provided by compiler-rt. Did I get it all right or maybe I'm missing something? libgcc provides both __aeabi_idiv0 and __aeabi_ldiv0 as weak symbols, any reasons not to do the same in compiler-rt? Or, to put it differently, why force external implementation of these functions? Thanks, Sergey

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See
