This should help gcc detect and use target ISA on x86_64 machines when -march is not used on cmdline [YOCTO #139] (From OE-Core rev: f9e410521c92e2458ba7e2ca63d28434618b9f25) Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
