FYI: On ia32, the compositor crashes on an exception because of an SSE instruction (movapd %xmm1,-0x298(%ebp)). If I am not mistaken, our FPU context switch routines are SSE compatible, but we simply don't set the specific bits in CR4 (OSFXSR, OSXMMEXCPT) to actually enable SSE. This should be easy to fix.
Well, it was even more banal than that. The plain old stack alignment. M.D. _______________________________________________ HelenOS-devel mailing list [email protected] http://lists.modry.cz/listinfo/helenos-devel
