[Bug libstdc++/50880] New: __complex_acosh() picks wrong complex branch
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50880 Bug #: 50880 Summary: __complex_acosh() picks wrong complex branch Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: krec...@ginac.de According to the C++ standard, acosh(complexT) should behave just like C99's cacosh(T complex) function. There, the branch cut is at values less than 1 along the real axis and the range of a half-strip of non-negative values along the real axis and in the interval [-i*pi,+i*pi] along the imaginary axis. The implementation in tr1/complex gets this wrong. The result returned by __complex_acosh() are all wrong in the lower complex plain. It can be easily fixed. I'm attaching a patch.

This is making it difficult to provide any better debug info. (I've tried setting DYLD_LIBRARY_PATH - at least as far as it's listed in the log - but no change).

Thus, to understand and clarify why this has not been noticed so far, you are
on a target which doesn't support in the underlying C library these complex
functions, right? Because normally (eg, on Linux) these days we just forward to
__builtin_cacosh*, the code you are touching is just a surrogate, a
fallback, which doesn't get right all the special cases, NaNs, infinity.
Anyway, a similar tweak would touch also the C++11 version in std::
Gaby, can you have a look to this, double check the patch? For your convenience
the surrounding code is:
templatetypename _Tp
std::complex_Tp
__complex_acosh(const std::complex_Tp __z)
{
std::complex_Tp __t((__z.real() - __z.imag())
* (__z.real() + __z.imag()) - _Tp(1.0),
_Tp(2.0) * __z.real() * __z.imag());
__t = std::sqrt(__t);
return std::log(__t + __z);
}

See comment 11 for the patch (follow the link) and comment 12 for things which have to be done before it can be committed. (The one of comment 5 is more a hack than a proper patch.) The best way is probably to implement it first for the common x86-64 and, when the design is OK (i.e. the patch is approved and committed), to do likewise for each of the other targets. If that's done, the front end can finally be changed.

--- Comment #3 from Richard Guenther rguenth at gcc dot gnu.org 2011-10-27
10:12:59 UTC ---
So it means that for constants we cannot really propagate address-taken
string-csts (or any other csts) but we have to use CONST_DECLs, give them
global scope and eventually register them with the varpool. Even without
LTO and for
const char *return_foo (void) { return foo; }
int main()
{
if (return_foo () != return_foo ())
abort ();
}
if we inline return_foo into main twice and fail to constant-propagate
and thus fold the equality on the tree level (we can do that, C does
say whether foo != foo should be true or false), with -fno-merge-constants
we would fail the testcase if we did not (by luck, I guess) share
the STRING_CST.
For LTO we cannot rely on that luck.
Honza, do we register CONST_DECLs with the varpool at all? Or how would
we be able to guarantee that we emit them only once?
Probably not really P1, as a non-stage1 fix is likely a bit invasive
(not sure if surgery at lto streaming time is possible).

So with the optimization it at least should not print

Cannot access memory at address 0x0
but instead
(gdb) print *p[1]
optimized out
not sure if that is a gdb bug though ('p' is optimized out - does the

11:00:49 UTC ---
I suppose it's just completely optimized away at -O1+ and thus broken
unconditionally. Shift lowering gives us
vuchar_1 = { 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4 };
vchar0_2 = { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 };
vchar1_3 = { -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1
};
D.2720_7 = BIT_FIELD_REF vchar1_3, 8, 0;
D.2721_8 = D.2720_7 1;
D.2722_9 = BIT_FIELD_REF vchar1_3, 8, 8;
D.2723_10 = 1;
D.2724_11 = BIT_FIELD_REF D.2723_10, 8, 8;
and that last two lines already look completely bogus...
We are lowering from
vuchar_1 = { 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4 };
vchar0_2 = { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 };
vchar1_3 = { -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1
};
i1.0_4 = vchar1_3 1;
i1 = i1.0_4;
D.2714_5 = BIT_FIELD_REF i1, 8, 8;
but the generic binary lowering and do_binop do not handle a scalar
RHS separately but do
static tree
do_binop (gimple_stmt_iterator *gsi, tree inner_type, tree a, tree b,
tree bitpos, tree bitsize, enum tree_code code)
{
a = tree_vec_extract (gsi, inner_type, a, bitsize, bitpos);
b = tree_vec_extract (gsi, inner_type, b, bitsize, bitpos);
return gimplify_build2 (gsi, code, inner_type, a, b);
that of course only works for element 0.
We came here via
gcc_assert (code != VEC_LSHIFT_EXPR code != VEC_RSHIFT_EXPR);
new_rhs = expand_vector_operation (gsi, type, compute_type, stmt, code);
(gdb) p code
$6 = LSHIFT_EXPR
Fixing it in do_binop like
static tree
do_binop (gimple_stmt_iterator *gsi, tree inner_type, tree a, tree b,
tree bitpos, tree bitsize, enum tree_code code)
{
if (TREE_CODE (TREE_TYPE (a)) == VECTOR_TYPE)
a = tree_vec_extract (gsi, inner_type, a, bitsize, bitpos);
if (TREE_CODE (TREE_TYPE (b)) == VECTOR_TYPE)
b = tree_vec_extract (gsi, inner_type, b, bitsize, bitpos);
return gimplify_build2 (gsi, code, inner_type, a, b);
is easiest.
