[Qemu-devel] [PATCH v2] tcg/i386: Use GDB JIT debugging interface only for hosts with ELF |
Date: |
Sat, 7 Apr 2012 17:53:04 +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.
v2:
Compile tcg_register_jit only for ELF host machines.
This fixes builds for MinGW32 (thanks, Blue Swirl).
