165 So, the tls register is emulated by the kernel.
166 This emulated value is set by the __NR_ARM_set_tls syscall.
167 The emulated value must be read by the kernel helper function
168 located at 0xffff0fe0.
169
170 The emulated tlsptr is located at 0xffff0ff0
171 (so slightly after the kernel helper function).
172 Note that applications are not supposed to read this directly.
173
174 For compatibility : if there is a hw tls register, the kernel
175 will put at 0xffff0fe0 the instructions to read it, so
176 as to have old applications calling the kernel helper
177 working properly.
178
179 For having emulated guest TLS working correctly with
180 Valgrind, it is needed to execute the syscall to set
181 the emulated TLS value in addition to the assignment
182 of TPIDRURO.
183
184 Note: the below means that if we need thread local storage
185 for Valgrind host, then there will be a conflict between
186 the need of the guest tls and of the host tls.
187 If all the guest code would cleanly call 0xffff0fe0,
188 then we might maybe intercept this. However, at least
189 __libc_preinit reads directly 0xffff0ff0.
