arch/x86/include/asm/vdso.h:            if (!builtin_strcmp(symbol, vdso_x86_symbols[i]))
arch/x86/include/asm/vdso.h:    if (builtin_memcmp(ehdr->e_ident, vdso_ident, sizeof(vdso_ident))) {
arch/x86/include/asm/vdso.h: builtin_strcmp(&section_names[shdr->sh_name],
arch/x86/include/asm/vdso.h: builtin_strcmp(&section_names[shdr->sh_name],
arch/x86/include/asm/vdso.h: builtin_strcmp(&section_names[shdr->sh_name],
arch/x86/include/asm/vdso.h:                    builtin_memcpy(t->sym[k].name, vdso_x86_symbols[k],

they are used in inline functions
