[Qemu-devel] [PATCH] tcg/i386: Use GDB JIT debugging interface only for


From: Stefan Weil
Subject: [Qemu-devel] [PATCH] tcg/i386: Use GDB JIT debugging interface only for hosts with ELF
Date: Fri, 6 Apr 2012 08:08:19 +0200

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.
