20141231:
|
||||||
|
Clang, llvm and lldb have been upgraded to 3.5.0 release.
|
||||||
|
|
||||||
|
As of this release, a prerequisite for building clang, llvm and lldb is
|
||||||
|
a C++11 capable compiler and C++11 standard library. This means that to
|
||||||
|
be able to successfully build the cross-tools stage of buildworld, with
|
||||||
|
clang as the bootstrap compiler, your system compiler or cross compiler
|
||||||
|
should either be clang 3.3 or later, or gcc 4.8 or later, and your
|
||||||
|
system C++ library should be libc++, or libdstdc++ from gcc 4.8 or
|
||||||
|
later.
|
||||||
|
|
||||||
|
On any standard FreeBSD 10.x or 11.x installation, where clang and
|
||||||
|
libc++ are on by default (that is, on x86 or arm), this should work out
|
||||||
|
of the box.
|
||||||
|
|
||||||
|
On 9.x installations where clang is enabled by default, e.g. on x86 and
|
||||||
|
powerpc, libc++ will not be enabled by default, so libc++ should be
|
||||||
|
built (with clang) and installed first. If both clang and libc++ are
|
||||||
|
missing, build clang first, then use it to build libc++.
|
||||||
|
|
||||||
|
On 8.x and earlier installations, upgrade to 9.x first, and then follow
|
||||||
|
the instructions for 9.x above.
|
||||||
|
|
||||||
|
Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by
|
||||||
|
default, and do not build clang.
|
||||||
|
|
||||||
|
Many embedded systems are resource constrained, and will not be able to
|
||||||
|
build clang in a reasonable time, or in some cases at all. In those
|
||||||
|
cases, cross building bootable systems on amd64 is a workaround.
|
||||||
|
|
||||||
|
This new version of clang introduces a number of new warnings, of which
|
||||||
|
the following are most likely to appear:
|
||||||
|
|
||||||
|
-Wabsolute-value
|
||||||
|
|
||||||
|
This warns in two cases, for both C and C++:
|
||||||
|
* When the code is trying to take the absolute value of an unsigned
|
||||||
|
quantity, which is effectively a no-op, and almost never what was
|
||||||
|
intended. The code should be fixed, if at all possible. If you are
|
||||||
|
sure that the unsigned quantity can be safely cast to signed, without
|
||||||
|
loss of information or undefined behavior, you can add an explicit
|
||||||
|
cast, or disable the warning.
|
||||||
|
|
||||||
|
* When the code is trying to take an absolute value, but the called
|
||||||
|
abs() variant is for the wrong type, which can lead to truncation.
|
||||||
|
If you want to disable the warning instead of fixing the code, please
|
||||||
|
make sure that truncation will not occur, or it might lead to unwanted
|
||||||
|
side-effects.
|
||||||
|
|
||||||
|
-Wtautological-undefined-compare and
|
||||||
|
-Wundefined-bool-conversion
|
||||||
|
|
||||||
|
These warn when C++ code is trying to compare 'this' against NULL, while
|
||||||
|
'this' should never be NULL in well-defined C++ code. However, there is
|
||||||
|
some legacy (pre C++11) code out there, which actively abuses this
|
||||||
|
feature, which was less strictly defined in previous C++ versions.
|
||||||
|
|
||||||
|
Squid and openjdk do this, for example. The warning can be turned off
|
||||||
|
for C++98 and earlier, but compiling the code in C++11 mode might result
|
||||||
|
in unexpected behavior; for example, the parts of the program that are
|
||||||
|
unreachable could be optimized away.
|
||||||
|
|
||||||
|
20141222:
|
||||||
|
The old NFS client and server (kernel options NFSCLIENT, NFSSERVER)
|
||||||
|
kernel sources have been removed. The .h files remain, since some
|
||||||
|
utilities include them. This will need to be fixed later.
|
||||||
|
If "mount -t oldnfs ..." is attempted, it will fail.
|
||||||
|
If the "-o" option on mountd(8), nfsd(8) or nfsstat(1) is used,
|
||||||
|
the utilities will report errors.

|
||||||
|
Function
|
||||||
|
.Fn dwarf_get_section_max_offsets_b
|
||||||
|
retrieves the sizes of the DWARF sections in a DWARF debug context.
|
||||||
|
Argument
|
||||||
|
.Ar dbg
|
||||||
|
should reference a DWARF debug context allocated using
|
||||||
|
.Xr dwarf_init 3 .
|
||||||
|
The function stores the size of each DWARF section to the location
|
||||||
|
pointed to by the argument corresponding to the section name.
|
||||||
|
If a DWARF section does not exist, the location pointed to by the
|
||||||
|
argument corresponding to that section will be set to zero.
|
||||||
|
.Pp
|
||||||
|
A value of NULL may be used for any of the arguments

Function

.Fn dwarf_get_section_max_offsets_b

section present.
|
||||||
|
On stepping past the last
|
||||||
|
.Dq \&.debug_types
|
||||||
|
section left in the debug context, function
|
||||||
|
.Fn dwarf_next_types_section
|
||||||
|
returns
|
||||||
|
.Dv DW_DLV_NO_ENTRY .
|
||||||
|
The next call to the function will restart from the first
|
||||||
|
.Dq \&.debug_types
|
||||||
|
section in the debug context.
|
||||||
|
.Pp
|
||||||
|
Application code should call function
|
||||||
|
.Xr dwarf_next_cu_header_c 3
|
||||||
|
to iterate though the type units associated with the current
|
||||||
|
.Dq \&.debug_types
|
||||||
|
section.
|
||||||
|
.Sh RETURN VALUES
|
||||||
|
On success, function
|
||||||
|
.Fn dwarf_next_types_section
|
||||||
|
returns
|
||||||
|
.Dv DW_DLV_OK .
|
||||||
|
.Pp
|
||||||
|
In case of an error, it returns
|
||||||
|
.Dv DW_DLV_ERROR
|
||||||
|
and sets argument
|
||||||
|
.Ar err .
|
||||||
|
When there are no more
|
||||||
|
.Dq \&.debug_types
|
||||||
|
sections left to traverse, it returns
|
||||||
|
.Dv DW_DLV_NO_ENTRY .
|
||||||
|
.Sh COMPATIBILITY
|
||||||
|
This function is an extension to the
|
||||||
|
.Xr DWARF 3
|
||||||
|
API.
|
||||||
|
.Sh ERRORS
|
||||||
|
The
|
||||||
|
.Fn dwarf_next_types_section
|
||||||
|
function may fail with the following errors:
|
||||||
|
.Bl -tag -width ".Bq Er DW_DLE_ARGUMENT"
