How do you build the android toolchain? Is it manual or do you have this scripted? In particular, do you use a pre-generated sysroot with Bionic or do you build the C library as part of the toolchain? Thanks.

Ah, except ada_demangle is also exported from libgnat*.so - wonder why the RTS
is built with IN_GCC.
In that case, guess the Ada folks need to decide which one of the two to keep,
and/or if one of them (either adadecode.[ch], or {include,libiberty}/* one
shouldn't be renamed to something else.
I haven't found any uses of either of those, except the libiberty demangler
that calls ada_demangle but it could very well call a static routine instead.

Slightly more reduced:
templatetypename T

T data[32];
};
auto
foo (Sint x)
{
return x;
}
The problem is that we create a RESULT_DECL with NULL DECL_SIZE, and gimplifier
ICEs on that. The RESULT_DECL is created in convert_for_initialization called
from check_return_expr I think.

Hm, that would be interesting. The applied patch changes the cost model to favor the unaligned store on VSX. Might be a place where it should be using the cost model but perhaps isn't? I'll look into it later this week.

fixes this for me. Without the REG_POINTER flags, aliasing is really confused
on what is a pointer and what is not, as the prologue of the misaligned memcpy
uses
adjusteddest = dest -align;
src = src - (adjusteddest - dest)
and from these only one has REG_POINTER flag after the propagation, so aliasing
makes a wrong decision from that.

Uh, just rediscovered this and recreated exactly the same reduced testcase!
Also, this variation which should not compile (because lookup should fail for
N::f):
namespace N
{
namespace detail
{
inline namespace ver
{
templatetypename T
void f();
}
}
templatetypename T
void
detail::f() { }
}
int main()
{
N::fint();
}
Somehow the fact N::detail::ver is an inline namespace causes N::detail::f to
also be declared in N.

[Bug libstdc++/65500] [5 Regression] FAIL: 17_intro/headers/c++2014/all_attributes.cc (test for excess errors)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65500 --- Comment #2 from Jonathan Wakely redi at gcc dot gnu.org --- (In reply to dave.anglin from comment #1) At one time, GCC was permissive about system header issues, particularly when they aren't really a problem. Is this still the case? It is, yes, but this specific diagnostic is an error not just a warning and it doesn't get disabled in system headers. It looks like an include hack would fix but there's probably more issues like this. I think this isn't a widespread problem. We only use these PTHREAD_XXX_INITIALIZER macros in a handful of places, and the other ones have been there for some time without problems. The choices seem to be: 1) Add an autoconf check to see if we can use the PTHREAD_RWLOCK_INITIALIZER macro in this way, so that it falls back to the constructor+destructor if the INITIALIZER macro can't be used. 2) Change the front-end to suppress narrowing errors in system headers. 3) Use fixincludes to change either the definition of __LWP_RWLOCK_VALID to (short)0x8c91 or change the definition of PTHREAD_RWLOCK_INITIALIZER to use (short)__LWP_RWLOCK_VALID I don't like (1) because it would be a bit fragile and could introduce silent ABI issues. If a later release of HPUX changes the INITIALIZER macro to avoid the narrowing conversion, or if a later release of G++ does (2), then the result of the autoconf check would change and would silently change whether a std::shared_timed_mutex uses a constructor/destructor or not. Different translation units built by different versions of GCC would disagree on how to construct the objects. Neither (1) nor (2) helps user code that wants to do: pthread_rwlock_t lock = PTHREAD_RWLOCK_INITIALIZER; which presumably fails with the same error when using g++ -std=c++11. So I think a fixincludes to cast the constant to (short) is the best option. If __LWP_RWLOCK_T is only used in the definition of PTHREAD_RWLOCK_INITIALIZER then changing its definition is probably the simplest: #define __LWP_RWLOCK_VALID (short)0x8c91 I don't have any HPUX machines to try that with, would you be able to?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65496 --- Comment #3 from Richard Henderson rth at gcc dot gnu.org --- (In reply to Jakub Jelinek from comment #2) Richard, any thoughts what to do about this? Avoid scheduling frame related instructions across conditional jumps? Something else? Yes, for the short term that will have to be a requirement in order to keep the unwind info happy. Something for the next stage1 is (1) Avoiding the use of bare /f, and thus also REG_FRAME_RELATED_EXPR, using instead always REG_CFA_*. I suspect that this insn 620 shouldn't actually be frame related at all, but is a part of a larger dwarf expression we're intending to construct. (2) Once we have an unambiguous note for everything, we can allow these insns to be scheduled across a conditional jump if we strip and collect those notes and place them after the conditional jump, probably on a fake insn like (insn/f (use (const_int 0)) (expr-list:REG_CFA_...

--- Comment #6 from Eric Botcazou ebotcazou at gcc dot gnu.org ---
The problematic statement is created by the gimple-match stuff:
Applying pattern match.pd:761, gimple-match.c:1727
Applying pattern match.pd:625, gimple-match.c:1525
gimple_simplified to _71 = I.3_30(ab) 4294967295;
_45 = _71;
and falls through the cracks of replace_stmt_with_simplification:
/* Play safe and do not allow abnormals to be mentioned in
newly created statements. See also maybe_push_res_to_seq. */
if ((TREE_CODE (ops[0]) == SSA_NAME
SSA_NAME_OCCURS_IN_ABNORMAL_PHI (ops[0]))
|| (ops[1]
TREE_CODE (ops[1]) == SSA_NAME
SSA_NAME_OCCURS_IN_ABNORMAL_PHI (ops[1]))
|| (ops[2]
TREE_CODE (ops[2]) == SSA_NAME
SSA_NAME_OCCURS_IN_ABNORMAL_PHI (ops[2])))
return false;
because ops[0] is already the new SSA_NAME (_71), which was created by:
tree
gimple_build (gimple_seq *seq, location_t loc,
enum tree_code code, tree type, tree op0, tree op1,
tree (*valueize)(tree))
{
tree res = gimple_simplify (code, type, op0, op1, seq, valueize);
if (!res)
{
if (gimple_in_ssa_p (cfun))
res = make_ssa_name (type);
else
res = create_tmp_reg (type);
gimple stmt = gimple_build_assign (res, code, op0, op1);
gimple_set_location (stmt, loc);
gimple_seq_add_stmt_without_update (seq, stmt);
}
return res;
}
I don't think that gimple_build can fail, so maybe the way out is to test
stmt_references_abnormal_ssa_name (SSA_NAME_DEF_STMT (ops[x]))
instead of just
SSA_NAME_OCCURS_IN_ABNORMAL_PHI (ops [x]))
in replace_stmt_with_simplification.

I'd like to do that ... maybe for GCC 6 though. It seems a bit late now to remove it without deprecation. Anyway, if you don't, bumping it to _8 and always using the new ABI sounds like a good plan to me. That proved quite difficult. My plan for now is to simply force --disable-libstdcxx-dual-abi when gnu-versioned-namespace is in use, so it bootstraps and can be used, just without the new GCC 5 hotness.

[Bug target/60408] ARM: inefficient code for vget_lane_f32 intrinsic
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60408 --- Comment #3 from Jim Wilson wilson at tuliptree dot org --- Even if we could fix the vec_extract constraints, we still end up with 3 instructions, as the optimizer can't do anything interesting with the vec_extract RTL. For a 32-bit SFmode value though, we can just use a subreg instead of a vector extract. The ARM port models the vector registers as 32-bit registers, so a subreg for a 32-bit mode will always be valid. Using a subreg instead of a vector extract here, I get 2 instructions. vmov.f32 s15, s0 vadd.f32 s0, s1, s15 That is because the register allocator thinks it needs a temp because inputs and ouputs partially overlap. That is a harder problem to fix. Subregs should also work for 64-bit modes. I have an experimental patch which is mostly untested. I don't know if this works for both big-endian and little-endian. I don't know if this works for all 32-bit modes and all vector types. Etc. All I know is that it seems to work for this testcase.

[Bug libstdc++/65147] alignment of std::atomic object is not correct
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65147 --- Comment #3 from Alexey Lapshin alexey.lapshin at oracle dot com --- (In reply to Jason Merrill from comment #2) This does seem like a bug. What is a proper behavior for G++ in this case ? should it always align std::atomic object of size 8 at 8 bytes ? Or should G++ just never inline implementation for atomic routine ? (see bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65149 when implementation of atomic routine was inlined for incorrectly aligned atomic object, which leads to BusError)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65515 --- Comment #4 from Jakub Jelinek jakub at gcc dot gnu.org --- This is from: 644 else if (TREE_CODE (expr) == FUNCTION_TYPE 645 || TREE_CODE (expr) == METHOD_TYPE) 646DFS_follow_tree_edge (TYPE_ARG_TYPES (expr)); where TYPE_ARG_TYPES contains a huge TREE_LIST chain (11 TREE_LIST nodes). From quick look at DFS::DFS_write_tree and DFS::DFS_write_tree_body, we don't really have anything there like GTY chain_next, which is clearly highly desirable here. Dunno if order matters here, if not, then for TS_LIST counting number of elements and if it is longer than say 10 or 100, use the vector + DFS_write_node from the end to start, could work.

Bug ID: 65529
Summary: [5 Regression][SH] gcc.dg/pr29215.c failing

Status: UNCONFIRMED
Severity: normal

Target: sh*-*-*
The test case for PR 29215 started to fail on SH:
FAIL: gcc.dg/pr29215.c scan-tree-dump-not gimple memcpy
Looking at the assembly output of the test case, the memcpy is optimized away,
albeit at a later stage during compilation through builtin expansion.
One option would be to scan the final assembly output for 'memcpy' symbols:

However, PR 29215 was specifically about optimizing away memcpy at the tree
level, so I'm not sure whether this is an appropriate fix. Something else
must have changed to trigger the new failure ...
In the gimple dump, the foo is:
foo (int arg1, int arg2, int arg3, int arg4, int arg5)
{
unsigned int D.1477;
void * D.1478;
void * D.1479;
void * D.1480;

D.1477 = MEM[(char * {ref-all})arg1];
MEM[(char * {ref-all})buf] = D.1477;
D.1478 = buf + 4;
__builtin_memcpy (D.1478, arg2, 4);
D.1479 = buf + 8;
__builtin_memcpy (D.1479, arg3, 4);

__builtin_memcpy (D.1480, arg4, 4);
D.1481 = buf + 16;
__builtin_memcpy (D.1481, arg5, 4);
}

In fact, I think it's better to do all the trans-array.c code inside gfc_conv_resolve_dependencies without adding the gfc_ss_info flag. There is also the case of typebound procedures and procedure pointer components, for which we should generate a temporary in any case. I think this case is something that was overlooked by the standard commitee when they introduced the PURE attribute. Maybe they can provide some kind of REALLY_PURE attribute (or PURE ELEMENTAL, different from regular ELEMENTAL) that avoids generating temporaries everywhere? Or maybe the function Fred should bee IMPURE ELEMENTAL? Anyway, I think we should not rush to fix this before we are sure that the standard committee really expects temporaries (almost) everywhere array elemental functions are involved. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug preprocessor/8270] [4.8/4.9/5 Regression] back-slash white space newline with comments, no warning
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=8270 --- Comment #57 from Kai Tietz ktietz at gcc dot gnu.org --- (In reply to doug mcilroy from comment #56) (In reply to Kai Tietz from comment #55) Comment #55 overlooks the Standard's translation phase 1, which replaces an implementation-defined end-of-line indicator with a new-line character. GCC's convention of including in the end-of-line indicator any white space that is preceded by a backslash conforms, though it may be a surprise. Sure, sorry for omitting that. Common understanding of multibyte (this term is indeed misleading here) newline characters are in common the combination of '\r' and '\n'. So by interpreting any whitespace + new-line being seen as a single-character is valid, but has indeed semantic differences. The surprise is perversely out of sympathy with the raison d'etre of the standard--maximal portability. It is incompatible with the most direct (and historically prior) implementations, wherein the end-of-line indicator is simply a new-line character. Agreed, and we should at least consider to provide an option - beside the necessary warning - to not strip whitespaces from right-handside of lines containing a backslash at line's end. Should we use an existing option (like -ansi), or introduce new option for this? A suitable fix is to warn when white space occurs in an end-of-line indicator. This will break no code that GCC currently compiles, yet draw attention to the nonportable construct. Well, in general we are warning, but within comments. For C-style comments there is indeed not much reason to warn, as there is no semantic difference. But for C++-style comments we should, as here indeed a semantic difference can occure for gnu-style end-of-line treating
