From c170cb66490aa20bfc8d2c2421481dd9195dbb8b Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Fri, 6 Apr 2012 08:06:41 +0200 Subject: tcg/i386: Use GDB JIT debugging interface only for hosts with ELF Not all i386 / x86_64 hosts use ELF. Ask the compiler whether ELF is used. On w64, gdb crashes when ELF_HOST_MACHINE is defined.
