-march=armv5't'e means that CPU can execute thumb ISA, we do not need to tie this to exclusively generating thumb ISA, this change means that when we have thumb in tune features then it can use 't' in -march options irrespective of ISA being thumb or arm. This fixes derivative of armv5 tunes and paves way for gcc9 where e.g. armv5e is dropped and minimum arch supported is armv5te (From OE-Core rev: 49bc3eab2897307a92b538a045e3d4dce245b0e0) Signed-off-by: Khem Raj <raj.khem@gmail.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.
