glibc/elf/tst-tlsmod3.c
Roland McGrath e6f526809d * elf/tst-tlsmod4.c (in_dso): Insert a random library call before use
of the TLS macros, otherwise the compiler might not have initialized
	the PIC register yet when we use the PLT via asm.
	* elf/tst-tlsmod3.c (in_dso2): Likewise.
	* elf/tst-tlsmod2.c (in_dso): Likewise.
