We can't direct development per se, but I personally feel that we've been too laissez faire over the past few cycles. I think we could do more to lead. Even the power to say no is a way to encourage development of other things. I've been hesitant to do that for fear of appearing overly strong, but if there's a mandate for that kind of leadership, then I think we could provide more of it. There is, however, a business model question as well. GCC does not have a single driving organization behind it; the silicon companies are interested in optimizing for their CPUs, Google is interested in general functionality and performance on its platforms of interest, and Red Hat and SuSE are focused on GNU/Linux features and performance. Questions like what's the plan for plugin infrastructure? implicitly ask who benefits enough from plugins -- whether in a monetary sense or just because they care enough -- to build plugin infrastructure? One of my current goals is to understand what things are possible in GCC and to drive funding for those features. I gave a talk at the Linux Foundation Collaboration Summit recently where I specifically highlighted plugin infrastructure and link-time/whole-program optimization as things I saw as potentially very valuable. -- Mark Mitchell CodeSourcery m...@codesourcery.com (650) 331-3385 x713

g++ generates code for constructors and destructors several times
Hello,
I have a question about code generated by g++.
When compiling a C++ class, even as simple as the one below,
the code for the constructor is instantiated twice and the code for the
destructor is instanciated twice or three times.
= myclass.cpp =
class MyClass
{
MyClass();
virtual ~MyClass();
};
MyClass::MyClass() {}
MyClass::~MyClass() {}
= /myclass.cpp =
I look at what this piece of code generates with:
g++ -S -o - myclass.cpp | less
And I can see the constructor twice.
The two functions _ZN7MyClassC2Ev and _ZN7MyClassC1Ev have exactly the same
code.
The destructor is present three times.
The functions _ZN7MyClassD2Ev, _ZN7MyClassD1Ev and _ZN7MyClassD0Ev have code
that is almost the same.
As the destructor is virtual, there is a virtual table which contains only
_ZN7MyClassD1Ev and _ZN7MyClassD0Ev. The third instance of the destructor code
(_ZN7MyClassD2Ev) doesn't appear in the virtual table.
If I remove the virtual keyword to make the class non-polymorphic, the
constructor is still compiled twice, as well as the destructor.
Would anyone have the patience to explain me why the constructors/destructors
are compiled several times ?
Thanks,
Lénaïc.

Re: [PATCH, RFC] plugin to warn about surplus includes
Bernhard == Bernhard Reutner-Fischer rep.dot@gmail.com writes: Bernhard - should handle structs. There are some other difficult cases. First, don't let this discourage you :-). I think this would be a useful feature. I think in general you cannot actually ever tell if a header is unused or not. Maybe it will only be used with some set of -D options, or when some configure option is passed in. So I think users of a plugin like this will always have to live with some false reporting. A header can #define things that are used by other headers. You would need to modify libcpp to detect this situation. Suppose a system header which is used includes a header which is not used. In this case, I think a warning about the inner header should be suppressed -- users generally can't do anything about this. (There are other worse cases like this. You might have a system header that seems directly unused, but it is the documented way to access some set of declarations. E.g., stdio.h might actually just be a bunch of #includes.) Tom

Which program is doing the dump? The generator programs (genattrtab,
etc.) produce different dumps from the compilers.
The 'i' after the 'B' represents an insn locator, a value of type
source_location aka location_t aka unsigned int. A generator program
will never print that value. A compiler will print it only if it has
a value--if the instruction has a known location. It will be printed
as filename:lineno when available.
The corresponding code in print-rtl.c is:
case 'i':
if (i == 4 INSN_P (in_rtx))
{
#ifndef GENERATOR_FILE
/* Pretty-print insn locators. Ignore scoping as it is mostly
redundant with line number information and do not print anything
when there is no location information available. */
if (INSN_LOCATOR (in_rtx) insn_file (in_rtx))

[Bug rtl-optimization/44194] struct returned by value generates useless stores
--- Comment #2 from jakub at gcc dot gnu dot org 2010-05-19 10:13 --- RTL DSE doesn't handle this because the call to bar, which isn't a const function, is considered a wild read and thus makes all stores necessary in the global as well as local algorithm. RTL DSE doesn't consider whether a frame based address could have possibly address taken or not and whether a call thus might read it or not. For tail calls before reload, perhaps we could handle tail calls similarly to const calls (be a read of all argument stores) with the addition that it would act as a read for all constant address stores (basically wild read for anything but frame based stores for the global algorithm, given that the stack is unwound before the tail call). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44194

At leas the stores to s have alias info:
(insn 12 10 14 2 t.c:7 (set (mem/s/c:DI (plus:DI (reg/f:DI 20 frame)
(const_int -16 [0xfff0])) [2 s+0 S8 A128])

(insn 14 12 17 2 t.c:7 (set (mem/s/c:DI (plus:DI (reg/f:DI 20 frame)
(const_int -8 [0xfff8])) [2 s+8 S8 A64])
(reg:DI 61)) 89 {*movdi_1_rex64} (nil))
so RTL DSE could check whether the stack slot is aliased at all.
The other memory temporary should be avoided at expansion time already.

[Bug target/44132] [4.6 Regression] emutls is broken under a range of circumstances.
--- Comment #21 from iains at gcc dot gnu dot org 2010-05-19 14:48 --- Created an attachment (id=20701) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20701action=view) latest.. this is mostly there ... might be worth trying on other platforms for feedback. without the catch-net of expr.c (which covered up several things.. ) When stuff works here it seems to work across the board now (including lto, whopr). three issues: 1/ Finalization of emutls control vars. 2/ Failure to emit constructor for uninitialized control vars. 3/ Small buglet in emutls. strategy for (1) a) finalization of the control vars is cascaded from finalization of the user-land vars in varpool.c b) a mop-up pass is carried out in emutls_final() - this is needed to pick up vars introduced by late passes (in particular by OMP). c) The initializer for init vars is applied and decl-finalized as soon as it is presented (we keep a mark to notice if the user tries to re-init). d) I've reorganized the code in varpool_finalize_decl () to ensure that varpool_enqueue_needed_node () is not done until after all the checks have been carried out for 'needed'. e) Removed some redundant calls to varpool_assemble_pending_decls () from varpool_finalize_decl (). 2. (a) some code re-organization in varasm.c to put all the emutls stuff together. (b) re-wrote the emutls structure to put the pointer at the start. (c) all tls control vars are static and they all need to be constructed - (FWIW DECL_COMMON() was never set anyway)/ 3. I put some comments into emutls.c since I had to figure it out ... and a minor bug that would hit after you reached 32 emutls vars. I'd welcome feedback on the approach(es) and whether it helps on other EMUTLS platforms. What is **NOT** fixed: A there is still some leakage in OMP (some interaction with threadprivate) I will carry on looking at that ... B PR43602 -- the tree-profile pass generates gimple directly without considering that it might need to be further gimplifed... C PR44140 -- although it shows up in a tls test is not realted to these issues. -- iains at gcc dot gnu dot org changed: What|Removed |Added Attachment #20688|0 |1 is obsolete|| Attachment #20693|0 |1 is obsolete|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44132

[Bug debug/44113] bad debugging information for unrolled loops
--- Comment #5 from jakub at gcc dot gnu dot org 2010-05-19 14:52 --- The problem is just that there are no instructions with locus on line 4 - with unrolling no traces of the for loop in the assembly remains and all instructions in the body have line 5 and immediately after it another unrolled iteration has the same line. Apparently gdb on next just puts a breakpoint on the first insn after it that has different file or line number. GCC could emit extra .loc 1 5 0 directives which would just add another row in the line table, or .loc 1 5 0 is_stmt 0 right after the first insn and .loc 1 5 0 is_stmt 1 back before first insn of the next iteration, but apparently this doesn't change anything in gdb. Not even lying and alternating .loc 1 5 0 and .loc 1 5 1 helps. And, putting extra .loc 1 4 0 covering no instructions doesn't change anything either. So I'm afraid there is nothing to do here on the gcc side, except lying that some insn comes from some other line (and for unrolling where the body is just one insn there is nothing to do at all). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44113

--- Comment #22 from iains at gcc dot gnu dot org 2010-05-19 14:54 --- I would imagine that this will ultimately affect all EMUTLS targets even tho it's against darwin. tree-profile.c is generating gimple directly for the inserted statements - AFAICT it's assuming that these don't need further expansion/gimplification... We need to substitute a reference and call for each emutls var ref. so that needs to be stuffed in and gimplified.. on my TODO if unless someone gets there first .. -- iains at gcc dot gnu dot org changed: What|Removed |Added CC|developer at sandoe-|iains at gcc dot gnu dot org |acoustics dot co dot uk | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43602
