Since ltp contains x86-64 assembler which uses the frame-pointer register, it will trigger below error when build ltp with -fno-omit-frame-pointer on x86-64. | cve-2015-3290.c: In function 'child_thread': | cve-2015-3290.c:416:1: error: bp cannot be used in asm here And there is also some comment as below in the source file ltp/20180515-r0/git/testcases/cve/cve-2015-3290.c * Build with -O2. Don't use -fno-omit-frame-pointer. So explicitly set -fomit-frame-pointer on x86-64 for compiler to fix the above build error.

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.
