Re: [patch c++]: Fix type_info struct for llp64 targets
Ping
2012/12/21 Kai Tietz ktiet...@googlemail.com:
Hello,
this patch fixes the layout of the info_type-s for llp64 target. We
used here 'long' type instead
of pointer-scalar-witdth type. That's an issue for llp64 targets.
I introduced for that the LONGPTR_T helper-macro, which has either
scalar-size of 'long' type, or
of 'long long' type's size, if pointer is larger then scalar-size of
'long' type.
ChangeLog
2012-12-21 Kai Tietz
* rtti.c (LONGPTR_T): New helper-macro.
(get_pseudo_ti_init): Initialize offset_type by LONGPTR_T
type instead of 'long' type.
(create_tinfo_types): Use for offset/flags field LONGPTR_T
type instead of 'long' type.
Tested for x86_64-w64-mingw32, i686-w64-mingw32, and
x86_64-unknown-linux-gnu. Ok for apply?
Regards,
Kai

Technically yes, but all input operands are matched to outputs, so in

Re: [patch, fortran] PR48976 INQUIRE with STREAM= not supported
Dear Jerry, thanks for the patch.However, I wonder about the following: Will that be backward compatible with binaries compiled with GCC 4.8 or will that cause problems? I have the feeling that it is okay as the flag (cf2) indicating whether stream= is present has still the same type and iqstream comes last in st_parameter_inquire and is only set if (cf2 IOPARM_INQUIRE_HAS_STREAM). Can confirm that there is no backward-compatibility issue? If there isn't, the patch is okay.

Re: [patch, fortran] PR48976 INQUIRE with STREAM= not supported
On 12/27/2012 03:12 AM, Tobias Burnus wrote: Dear Jerry, thanks for the patch.However, I wonder about the following: Will that be backward compatible with binaries compiled with GCC 4.8 or will that cause problems? I have the feeling that it is okay as the flag (cf2) indicating whether stream= is present has still the same type and iqstream comes last in st_parameter_inquire and is only set if (cf2 IOPARM_INQUIRE_HAS_STREAM). Can confirm that there is no backward-compatibility issue? If there isn't, the patch is okay. Tobias The cf2 flag exists and we are using the next unused bit as defined in ioparm.def. No previous version of the frontend or the runtime library use or look at this bit so there will be no compatibility issues. I named the stream pointer iqstream to avoid it being color highlighted. My editor highlights stream has a C key word. I will change the constant parameter IOPARM_INQUIRE_HAS_STREAM to IOPARM_INQUIRE_HAS_IQSTREAM just for consistency so that in the future, maintainers will know it is related to the use of the iqstream pointer. I will commit the patch later today and thanks for the review. Regards, Jerry
[PATCH] AIX native TLS support [3/?]
This patch gets GCC support for native TLS on AIX working and passing
most tests.
The patch shifts the creation of the qualified symbol name from
output_toc() to rs6000_legitimize_tls_address_aix(). I was hoping that
the separate SYMBOL_REF would prevent RTL fwprop from becoming
confused about the symbols, but no such luck. The re-write still makes
things a little cleaner.
Also, private TLS data (static variables with non-zero initializers)
are not decorated with the TLS CSECT qualifier so that the AIX
assembler and linker resolve it correctly.
To prevent fwprop from breaking things, I need to prevent
rs6000_delegitimize_address from associating TLS TOC references with
the original symbol. The rs6000 port uses the constant pool to manage
the TOC. However, for TLS symbols, the value in the TOC is not
equivalent to the symbol itself. The RTL fwprop pass thinks that it
can associate the result of a TLS access, which materializes the
symbol in a register, with the value in the constant pool and avoid
re-loading the TOC value. This does not work and passes a garbage
value to subsequent TLS calls, which produce garbage results. The two
solutions are either hide the TLS constant pool values by not
delegitmizing them or completely re-writing the TOC support to use a
pool separate from the constant pool. I chose the former because TLS
is a scarce resource and its usage should be minimal anyway.
Bootstrapped on powerpc-ibm-aix7.1.0.0.
Thanks, David

[Patch, Fortran] PR55758 - Non-C_Bool handling with BIND(C)
Dear all,
See also the discussion in the thread starting at
http://gcc.gnu.org/ml/fortran/2012-12/msg00135.html
a) The Fortran standard only defines LOGICAL(kind=C_Bool) as being
interoperable with C - no other LOGICAL type. That matches GCC: With gcc
(the C compiler) only _Bool is a BOOLEAN_TYPE with TYPE_PRECISION == 1.
Hence, this patch rejects other logical kinds as dummy argument/result
variable in BIND(C) procedures if -std=f2003/f2008/f2008ts is specified
(using -pedantic, one gets a warning).
b) As GNU extension, other logical kinds are accepted in BIND(C)
procedures; however, as the main use of LOGICAL(kind=4) (for BIND(C)
procedures) is to handle logical expressions which use C's int, one has
to deal with all integer values and not only 0 and 1. Hence, a normal
integer type is used internally in that case. That has been done to
avoid surprises of users and hard to trace bugs.
Note: logical(c_bool) and all logicals which are not dummy or result
variables of a bind(C) procedure remain BOOLEAN_TYPEs with
TYPE_PRECISION == 1 bit. For those a .true. with internal value -1
will lead the surprising result .not.(-1) = (-2) = .true., i.e. .true.
== .not. .true. But that's simply an invaliduse of those logicals and
not a bug in the compiler. (- won't fix).
Build and regtested on x86-64-gnu-linux.
OK for the trunk?
Tobias

Hi,
Currently Android dynamic loader does not support indirect functions
(And I don't think that

The attached patch is indended to add the target hook for indicating
the support of ifunc on target.
The idea behind the patch looks OK, but implementation needs a bit of tweaking.
As Joseph mentioned, you need to convert this macro into a target hook. GCC is
making a gradual transition away from target macros to target hook functions,
and all new hooks should be added as functions, unless there is a compelling
argument to make it a macro. For an example of adding a target hook function
see rev 194608 (among many others).

I ended up fixing them by implementing Geoffrey's proposed resolution for LWG issue 2118, which isn't official yet but is better than what we had before so is a step in the right direction, even if it ends up needing further revision when 2118 is resolved. * include/std/functional (_Require): Move to ... * include/std/type_traits (_Require): ... here. * include/bits/shared_ptr_base.h (__shared_count::_S_create_from_up): Handle unique_ptr for arrays or with custom pointer types. (__shared_ptr::__shared_ptr(unique_ptr_Tp1, _Del): Likewise. * include/bits/unique_ptr.h (unique_ptr_Tp[], _Dp): Use _Dp::pointer if defined. Implement proposed resolution of LWG 2118. * testsuite/20_util/shared_ptr/cons/unique_ptr_array.cc: New. * testsuite/20_util/unique_ptr/assign/cv_qual.cc: New. * testsuite/20_util/unique_ptr/cons/array_convertible_neg.cc: New. * testsuite/20_util/unique_ptr/cons/convertible_neg.cc: New. * testsuite/20_util/unique_ptr/cons/cv_qual.cc: New. * testsuite/20_util/unique_ptr/modifiers/cv_qual.cc: New. * testsuite/20_util/unique_ptr/requirements/pointer_type_array.cc: New. * testsuite/20_util/shared_ptr/cons/unique_ptr.cc: Adjust comments. * testsuite/20_util/unique_ptr/cons/pointer_array_convertible_neg.cc: Likewise. * testsuite/20_util/unique_ptr/requirements/pointer_type.cc: Likewise. * testsuite/20_util/bind/ref_neg.cc: Adjust dg-error line number. * testsuite/20_util/declval/requirements/1_neg.cc: Likewise. * testsuite/20_util/default_delete/48631_neg.cc: Likewise. * testsuite/20_util/shared_ptr/cons/43820_neg.cc: Likewise. * testsuite/20_util/unique_ptr/assign/48635_neg.cc: Likewise. * testsuite/20_util/unique_ptr/modifiers/reset_neg.cc: Adjust dg-error text. * testsuite/20_util/unique_ptr/cons/ptr_deleter_neg.cc: Use different instantiations so static_assert fails for each. Thanks to Geoffrey and Lawrence for input and test cases. Tested x86_64-linux, committed to trunk. I'm not getting errors when converting from derived to base. E.g. the following compiles, when it should not. std::unique_ptrconst base [] acb_ad(new derived[3]); -- Lawrence Crowl
[patch, libgfortran] PR55818 Reading a REAL from a file which doesn't end in a new line fails
Hi, The attached patch fixes this problem by not calling hit_eof if EOF can be a valid separator. Regression tested on x86-64. OK for trunk with test case from PR?

Re: [PATCH] Function Multiversioning Bug, checking for function versions
