error_handler: add no_native compiler directive
As suggested by Mikael Pettersson: "I agree there _may_ be a recursion between the native-traps-to-beam mechanism and the error_handler module. However, the real problem is that the chosen mechanism (point to target MFA's BEAM code) isn't flexible enough to handle newer features like on_load or (apparently) a native-mode error_handler. My planned fix is to make remote calls link to the target's Export* instead, just like BEAM does, which should solve the problems. This will however require HiPE to use different kinds of trap-to-beam stubs for remote and local calls, since local calls must not and often cannot go via Export entries. A simpler workaround for the error_handler issue (which I couldn't reproduce) is to just never compile error_handler to native code. It's not like there's a lot to gain by doing that. Please try the patch below." Patch has been tested and confirmed to make --enable-native-libs useable. Signed-off-by: Mikael Pettersson <[email protected]> Acked-by: Tuncer Ayaz <[email protected]>
