------- Comment #1 from danglin at gcc dot gnu dot org 2008-11-27 04:08 -------
emutls_alloc is called with the following struct __emutls_object *:
(gdb)
emutls_alloc (obj=0x400011d0) at ../../../gcc/libgcc/../gcc/emutls.c:95
95 {
(gdb) p/x $r26
$7 = 0x400011d0
(gdb) p *(struct __emutls_object *) $r26
$8 = {size = 0, align = 0, loc = {offset = 2, ptr = 0x2}, templ = 0x0}
As a result, this code is executed in emutls_alloc:
/* We could use here posix_memalign if available and adjust
emutls_destroy accordingly. */
if (obj->align <= sizeof (void *))
{
ptr = malloc (obj->size + sizeof (void *));
if (ptr == NULL)
abort ();
((void **) ptr)[0] = ptr;
ret = ptr + sizeof (void *);
}
This causes the unaligned pointer.
(gdb) bt
#0 emutls_alloc (obj=0x400011d0) at ../../../gcc/libgcc/../gcc/emutls.c:104
#1 0x7ad79a04 in __emutls_get_address (obj=0x400011d0)
at ../../../gcc/libgcc/../gcc/emutls.c:180
#2 0x00002ee0 in test1_ ()
at /test/gnu/gcc/gcc/libgomp/testsuite/libgomp.fortran/pr25162.f:14
#3 0x00002e48 in MAIN__ ()
at /test/gnu/gcc/gcc/libgomp/testsuite/libgomp.fortran/pr25162.f:5
#4 0x00003278 in main (argc=1, argv=0xf100000)
at ../../../gcc/libgfortran/fmain.c:21
As far as I can see, the obj passed to __emutls_get_address is never
initialized. The call assembler is:
addil LR'__emutls_v.testcom_-$global$,%r27
copy %r1,%r28
ldo RR'__emutls_v.testcom_-$global$(%r28),%r26
.CALL ARGW0=GR
bl __emutls_get_address,%r2
nop
__emutls_v.testcom_ is allocated in the $BSS$ subspace:
.SPACE $PRIVATE$
.SUBSPA $BSS$
__emutls_v.testcom_ .comm 16
This is a regression, at least a testcase regression, because the tls tests
were previously skipped on this target.

Size of __emutls_v.testcom_ block is wrong, as well as generated code.
