Take l_tls_firstbyte_offset information into account. (CHECK_STATIS_TLS): _dl_allocate_static_tls can fail now. * sysdeps/generic/ldsodefs.h: Adjust _dl_allocate_static_tls prototype. * elf/Makefile: Add rules to build and run tst-tls14. * elf/tst-tls14.c: New file. * elf/tst-tlsmod14a.c: New file. * elf/tst-tlsmod14b.c: New file. --- elf/tst-tlsmod14a.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 elf/tst-tlsmod14a.c (limited to 'elf/tst-tlsmod14a.c') diff --git a/elf/tst-tlsmod14a.c b/elf/tst-tlsmod14a.c new file mode 100644 index 0000000000..4843e5937e --- /dev/null +++ b/elf/tst-tlsmod14a.c @@ -0,0 +1,36 @@ +#include +#include + + +#define AL 4096 +struct foo +{ + int i; +} __attribute ((aligned (AL))); + +static __thread struct foo f; +static struct foo g; + + +#ifndef FCT +# define FCT in_dso1 +#endif + + +int +FCT (void) +{ + puts (__func__); + + int result = 0; + + int fail = (((uintptr_t) &f) & (AL - 1)) != 0; + printf ("&f = %p %s\n", &f, fail ?
