[Help-smalltalk] [PATCH 1/2] jit: Flush the code for the runtime directives

[Holger Hans Peter Freyther]

From: Holger Hans Peter Freyther <address@hidden>

On x86/amd64 this will call mprotect with PROT_EXEC on the
allocated memory. This is fixing an infinite recursion in the
segfault handler of the garbage collection.

        * xlat.c: Use jit_flush_code for the runtime code.
