[Bug fortran/46540] libquadmath: Implement --disable-libquadmath
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46540 Tobias Burnus burnus at gcc dot gnu.org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||FIXED --- Comment #5 from Tobias Burnus burnus at gcc dot gnu.org 2010-12-10 12:41:14 UTC --- Close as FIXED. You now have: --disable-libquadmath to disable the configure and build of libquadmath/ --disable-libquadmath-support to disable the __float128-based REAL(16) support in gfortran and the dependence of libgfortran on libquadmath. The two options are can be used independently from each other; if you use only the first one (and build Fortran), you have to make a (the system's) libquadmath library available to configure.

Do you plan to backport it to 4.5 or should I close it as fixed? As things stand, I suspect that it's better to concentrate our efforts on making 4.6 fully functional on Darwin. However, if (a) all the changes are eligible (i.e. covered by 4.5-regression or pre-existing bugs) and (b) someone wants to do the back-port merge, I will be happy to review/test and commit it to 4.5 ...

Thus, if we can't really go through such issue in the constexpr code for 4.6.0 - because too risky, or whatelse - I would propose removing for now the constexpr specifiers from std::pair.

[Bug debug/46796] debug info missing builtin type names with lto
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46796 --- Comment #9 from Richard Guenther rguenth at gcc dot gnu.org 2010-12-10 14:32:48 UTC --- The volatile qualified case happens because dwarf2out.c wants to emit an unqualified variant first and gets at it via get_qualified_type which in turn uses check_qualified_type to pick one from the list of variant types. But as we never merge TYPE_DECLs we have different TYPE_NAMEs for the qualified and unqualified variants: (gdb) call debug_tree ($34) type_decl 0xb7758798 float type real_type 0xb7750900 float asm_written SF size integer_cst 0xb773f240 constant 32 unit size integer_cst 0xb773f078 constant 4 align 32 symtab 0 alias set -1 structural equality precision 32 pointer_to_this pointer_type 0xb7750a20 VOID file (null) line 0 col 0 align 1 (gdb) call debug_tree ($35) type_decl 0xb775857c float type real_type 0xb7750900 float asm_written SF size integer_cst 0xb773f240 constant 32 unit size integer_cst 0xb773f078 constant 4 align 32 symtab 0 alias set -1 structural equality precision 32 pointer_to_this pointer_type 0xb7750a20 VOID file (null) line 0 col 0 align 1 and thus get_qualified_type happily returns NULL which leads to name being set to NULL even though the original type does have a name in modified_type_die. Now. We probably should start to merge TYPE_DECLs at some point, even if it is only for memory use. But instead of /* This probably indicates a bug. */ else if (mod_type_die mod_type_die-die_tag == DW_TAG_base_type) add_name_attribute (mod_type_die, __unknown__); we could use TYPE_NAME of the original type here, it will have no qualifications anyway.

Hm, well. Then the debug machinery has to deal with type mismatches I guess.
But I wonder why we have debug-stmts for global variables anyway? I thought

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46829 --- Comment #10 from Vladimir Makarov vmakarov at redhat dot com 2010-12-10 15:45:33 UTC --- (In reply to comment #9) (In reply to comment #5) It should work for x86_64, not necessarily i?86. Do you mean -fsched-pressure should be able to solve the problem completely for x86-64? Vladimir: Do you have any idea which direction to go in order to solve this problem? Introducing of -fsched-pressure just decreased probability of the bug when 1st insn scheduling is used. The patch introducing -fsched-pressure contained some code in reload to decrease the probability even more. Unfortunately, it did not eliminated it fully. This bug can not be fixed in scheduler (or the solution, like not moving through insn referring for a hard register, will be too conservative especially for x86_64 and still will not fix it for x86) because the scheduler can not see all info handled by reload. IMHO, the right fix should be possibility to split live ranges for explicitly mentioned hard register. May be Jeff Law's current work will provide such feature. In any case, implementation of live range splitting in reload is too big and complicated job even for stage #1. There is no way to implement it at stage #3. It is also very unreasonable thing to do because any change in reload is usually very bug prone. I am sorry, but I don't see that it can be fixed for gcc4.6 fox x86/x86-64. Although it might be fixed for gcc4.7.

A little debugging shows the build dies in mksysinfo.go at
line 201, which is at
# The registers returned by PTRACE_GETREGS. This is probably
# GNU/Linux specific.
regs=`grep '^type _user_regs_struct struct' gen-sysinfo.go`
So, yes, building gccgo is linux specific.
Looking in gen-sysinfo.go, one finds the following
type _reg struct { r_r15 int64; r_r14 int64; r_r13 int64; r_r12 int64; r_r11
int64; r_r10 int64; r_r9 int64; r_r8 int64; r_rdi int64; r_rsi int64; r_rbp
int64; r_rbx int64; r_rdx int64; r_rcx int64; r_rax int64; r_trapno uint32;
r_fs uint16; r_gs uint16; r_err uint32; r_es uint16; r_ds uint16; r_rip int64;
r_cs int64; r_rflags int64; r_rsp int64; r_ss int64; }
which is probably the required list of registers.
Given that building gccgo appears to be restricted to linux,
why was configure successful? Should configure have errored
out stating that gccgo is not supported on FreeBSD?

Configuring with g++-4.5 (4.5.1-7ubuntu2) or g++-4.4 (Ubuntu/Linaro

[Bug bootstrap/45888] tm.texi generation is not portable, rule is broken
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45888 --- Comment #31 from Anh Vo anhvofrcaus at gmail dot com 2010-12-11 00:54:08 UTC --- (In reply to comment #30) (In reply to comment #29) gcc/tm.texi and gcc/tmp3-tm.texi did not have same same line ending. In fact, gcc/tm.texi contains 'ASCII English text, with very long lines' while gcc/tmp3-tm.texi has 'ASCII English text' only when examined with 'file' command. In addition, gcc/tm.texi is slightly larger in size (507 KB) than gcc/tmp3-tm.texi (493 KB). I don't understand this at all. The \r removal works for gcc/tm.texi, but not for gcc/tmp3-tm.texi? And yet the latter is smaller? Or does the latter have no line endings at all because you somehow untarred the source file with MacOs 9 style line endings? What size is your $(srcdir)/doc/tm.texi ? How many lines do the varyous tm.texi files have? (wc should tell) Could you show the start of these files with od, like shown in comment 13?

However, other problem surfaces. With Cygwin build, it complained assembly code as shown in error message below. This is clearly a separate issue. Please open a new PR for it, unless that has already been done, and/or the problem has been fixed, in the meantime. For MinGW build, it complained about lto plugin as shown below.

What about the floating-point types? Or would we rather have an
enum type_kind? Although that might be confused with what we used to
have for varargs before gimple, i.e. a kind of type.
I'd guess a separate hook; they tend to vary somewhat independently from
integer types. bool would probably also be separate. So you might have
hooks for: general integer types; bool; binary floating-point; decimal
floating-point; fixed-point; hook definitions would all have a
gcc_unreachable (); default case to catch inappropriate enum values being
passed in. And another hook for ADA_LONG_TYPE_SIZE (defaulting to
calling targetm.integer_type_size (itk_long)), I guess.
We don't have any current decimal floating or fixed-point type size macros
to replace. As discussed elsewhere, the stdint type, wchar type, and ada long
type sizes are best dealt with by having a hook to define the types in terms
of enum integer_type_kind, and then looking up the size of the type size for
that integer type.
I.e. first, we want to describe the C integer / bool / binary floating
type sizes with three hooks:
DEFHOOK_UNDOC
(integer_type_size,
,
int, (enum integer_type_kind),
legacy_integer_type_size)
DEFHOOK
(bool_type_size,
The size, in bits, of the boolean type used by most front ends that have
such\
a type. (Java is an exception, because the language defines the type size.)
\
The default is @code{CHAR_TYPE_SIZE}.,
int, (void),
default_bool_type_size)
DEFHOOK_UNDOC
(float_type_size,
,
int, (enum th_float_type),
legacy_float_type_size)
We should probably make the type name information corresponding to enum
integer_type_kind / enum th_float_type_size available independent of
the type nodes having been initialized, so that the preprocessor can use the
names without trouble.
In another patch, we can define stdint / wchar / ada long types
in therms of integer_type_kind.
There'll be slight overlap with the previously mentioned patch in that
we also need to move enum integer_type_kind to coretypes.h .
We should probably make the type name information corresponding to enum
integer_type_kind / enum th_float_type_size available independent of
the type nodes having been initialized, so that the preprocessor can use the
names without trouble.
DEFHOOK
(stdint_type,
Return the @code{enum integer_type_kind} value corresponding to @var{type}.
If the type does not exist, return itk_none.,
enum integer_type_kind, (enum th_stdint type),
default_stdint_type)
DEFHOOK
(size_type,
Return the @code{enum integer_type_kind} value corresponding to @var{type}.,
enum integer_type_kind, (enum th_size_type type),
default_size_type)
DEFHOOK
(atomic_type,
Return the @code{enum integer_type_kind} value corresponding to
@code{sig_atomic_t}.,
enum integer_type_kind, (void),
default_atomic_type)
DEFHOOK
(wchar_type,
Return the @code{enum integer_type_kind} value corresponding to @var{type}.,
enum integer_type_kind (enum th_wchar_type type),
default_wchar_type)
DEFHOOK
(ada_long_type,
Return the @code{enum integer_type_kind} value corresponding to the ada
@code{long} type. The default is to use the same type as for C.,
enum integer_type_kind (void),
default_ada_long_type)
When these two patches are in, we can then make another patch to replace
the macros of the sizes of stdint / wchar / ada long types with using
the above hooks to fist lookup the enum integer_type_kind of the type, and
then its size .
Yes, you could as a temporary transitional measure, like for other hooks,
but certainly I think all definitions of hooks in terms of the old macros
should be considered temporary with the aim being to convert all targets
and poison the macro names.
Yes, once the above outlined patches to hookize the consumer side are in,
and thus we have defined the interface, we can proceed at will to finish
the process. Although some definitions seem somewhat tangled, so some or
all of that might have to wait for 4.7, lest we break stuff close to the
release.
