The basic problem is that some mainstream programs cannot deal with the way
clang optimizes tail calls, as in this example:
int foo(void);
int bar(void) {
return foo();
}
where the call is transformed to:
calll .L0$pb
.L0$pb:
popl %eax
.Ltmp0:
addl $_GLOBAL_OFFSET_TABLE_+(.Ltmp0-.L0$pb), %eax
movl foo@GOT(%eax), %eax
popl %ebp
jmpl *%eax # TAILCALL
However, the GOT references must all be resolved at dlopen() time, and so this
approach cannot be used with lazy dynamic linking (e.g. using RTLD_LAZY), which
usually populates the PLT with stubs that perform the actual resolving.
This patch changes X86TargetLowering::LowerCall() to skip tail call
optimization, if the called function is a global or external symbol.
This fixes problems with loading X.org driver modules, which could occur
when X.org was compiled on i386 with tailcall optimization on, for which
ports r312583 was committed as a workaround. After this change, the
workaround can be removed.

ISelDAG: spot chain cycles involving MachineNodes
Previously, the DAGISel function WalkChainUsers was spotting that it
had entered already-selected territory by whether a node was a
MachineNode (amongst other things). Since it's fairly common practice
to insert MachineNodes during ISelLowering, this was not the correct
check.
Looking around, it seems that other nodes get their NodeId set to -1
upon selection, so this makes sure the same thing happens to all
MachineNodes and uses that characteristic to determine whether we
should stop looking for a loop during selection.

in the future in a backward compatible (API and ABI) way.
The cap_rights_t represents capability rights. We used to use one bit to
represent one right, but we are running out of spare bits. Currently the new
structure provides place for 114 rights (so 50 more than the previous
cap_rights_t), but it is possible to grow the structure to hold at least 285
rights, although we can make it even larger if 285 rights won't be enough.
The structure definition looks like this:
struct cap_rights {
uint64_t cr_rights[CAP_RIGHTS_VERSION + 2];
};
The initial CAP_RIGHTS_VERSION is 0.
The top two bits in the first element of the cr_rights[] array contain total
number of elements in the array - 2. This means if those two bits are equal to
0, we have 2 array elements.
The top two bits in all remaining array elements should be 0.
The next five bits in all array elements contain array index. Only one bit is
used and bit position in this five-bits range defines array index. This means
there can be at most five array elements in the future.
To define new right the CAPRIGHT() macro must be used. The macro takes two
arguments - an array index and a bit to set, eg.
#define CAP_PDKILL CAPRIGHT(1, 0x0000000000000800ULL)
We still support aliases that combine few rights, but the rights have to belong
to the same array element, eg:
#define CAP_LOOKUP CAPRIGHT(0, 0x0000000000000400ULL)
#define CAP_FCHMOD CAPRIGHT(0, 0x0000000000002000ULL)
#define CAP_FCHMODAT (CAP_FCHMOD | CAP_LOOKUP)
There is new API to manage the new cap_rights_t structure:
cap_rights_t *cap_rights_init(cap_rights_t *rights, ...);
void cap_rights_set(cap_rights_t *rights, ...);
void cap_rights_clear(cap_rights_t *rights, ...);
bool cap_rights_is_set(const cap_rights_t *rights, ...);
bool cap_rights_is_valid(const cap_rights_t *rights);
void cap_rights_merge(cap_rights_t *dst, const cap_rights_t *src);
void cap_rights_remove(cap_rights_t *dst, const cap_rights_t *src);
bool cap_rights_contains(const cap_rights_t *big, const cap_rights_t *little);
Capability rights to the cap_rights_init(), cap_rights_set(),
cap_rights_clear() and cap_rights_is_set() functions are provided by
separating them with commas, eg:
cap_rights_t rights;
cap_rights_init(&rights, CAP_READ, CAP_WRITE, CAP_FSTAT);
There is no need to terminate the list of rights, as those functions are
actually macros that take care of the termination, eg:
#define cap_rights_set(rights, ...) \
__cap_rights_set((rights), __VA_ARGS__, 0ULL)
void __cap_rights_set(cap_rights_t *rights, ...);
Thanks to using one bit as an array index we can assert in those functions that
there are no two rights belonging to different array elements provided
together. For example this is illegal and will be detected, because CAP_LOOKUP
belongs to element 0 and CAP_PDKILL to element 1:
cap_rights_init(&rights, CAP_LOOKUP | CAP_PDKILL);
Providing several rights that belongs to the same array's element this way is
correct, but is not advised. It should only be used for aliases definition.
This commit also breaks compatibility with some existing Capsicum system calls,
but I see no other way to do that. This should be fine as Capsicum is still
experimental and this change is not going to 9.x.

Fixed the Intel-syntax X86 disassembler to respect the (existing)
option for hexadecimal immediates, to match AT&T syntax. This also
brings a new option for C-vs-MASM-style hex.

Notable new features:
* Elliptic Curve Digital Signature Algorithm keys and signatures in
DNSSEC are now supported per RFC 6605. [RT #21918]
* Introduces a new tool "dnssec-verify" that validates a signed zone,
checking for the correctness of signatures and NSEC/NSEC3 chains.
[RT #23673]
* BIND now recognizes the TLSA resource record type, created to
support IETF DANE (DNS-based Authentication of Named Entities)
[RT #28989]
* The new "inline-signing" option, in combination with the
"auto-dnssec" option that was introduced in BIND 9.7, allows
named to sign zones completely transparently.

This is the gsoc-2011 project to clean up and backport multibyte support
from other nvi forks in a form we can use.
USE_WIDECHAR is on unless building for the rescue crunchgen. This should
allow editing in the native locale encoding.
USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now. This
adds the ability to do things like edit a KOI8-R file while having $LANG
set to (say) en_US.UTF-8. iconv is used to transcode the characters for
display.
Other points:
* It uses gencat and catopen/etc instead of homegrown msg catalog stuff.
* A lot of stuff has been trimmed out, eg: the perl and tcl bindings which
we could never use in base anyway.
* It uses ncursesw when in widechar mode. This could be interesting.

After configuring the interface, wait for the link to become active.
Many ethernet drivers reset the chip when we set multicast filters
(causing significant delays due to link re-negotiation) and, by the time
we start sending packets, they are discared instead of going to the ether.

New Features
Adds a new configuration option, "check-spf"; valid values are
"warn" (default) and "ignore". When set to "warn", checks SPF
and TXT records in spf format, warning if either resource record
type occurs without a corresponding record of the other resource
record type. [RT #33355]
Adds support for Uniform Resource Identifier (URI) resource
records. [RT #23386]
Adds support for the EUI48 and EUI64 RR types. [RT #33082]
Adds support for the RFC 6742 ILNP record types (NID, LP, L32,
and L64). [RT #31836]
Feature Changes
Changes timing of when slave zones send NOTIFY messages after
loading a new copy of the zone. They now send the NOTIFY before
writing the zone data to disk. This will result in quicker
propagation of updates in multi-level server structures. [RT #27242]
"named -V" can now report a source ID string. (This is will be
of most interest to developers and troubleshooters). The source
ID for ISC's production versions of BIND is defined in the "srcid"
file in the build tree and is normally set to the most recent
git hash. [RT #31494]
Response Policy Zone performance enhancements. New "response-policy"
option "min-ns-dots". "nsip" and "nsdname" now enabled by default
with RPZ. [RT #32251]

This patch implements __get_cpuid_max() as an inline and __cpuid()
and __cpuid_count() as macros to be compatible with GCC's cpuid.h.
It also adds bit_<foo> constants for the various feature bits as
described in version 039 (May 2011) of Intel's SDM Volume 2 in the
description of the CPUID instruction. The list of bit_<foo>
constants is a bit exhaustive (GCC doesn't do near this many). More
bits could be added from a newer version of SDM if desired.

This is a post point-zero bug-fix / fix-sharp-edges release, including
some workarounds for UTF-8 for people who haven't yet turned on WITH_ICONV.
The standard (n3242, section 17.6.1.1, paragraph 4) says that, because these are
declared as macros in the C specification (even though they are
implemented as functions in the C++ library) they should be in the global
namespace.
A surprising number of configure checks rely on this. It was broken by recent

FastISel can only append to basic blocks.
Compute the insertion point from the end of the basic block instead of
skipping labels from the front.
This caused failures in landing pads when live-in copies where inserted

I missed this change in r252720; without it, certain compilation flags
can cause exception labels to not be generated, but still referenced,
leading to link errors.

For now, sandboxing is done only if -n option was specified and neither -z nor
-V options were given. Because it is very common to run tcpdump(8) with the -n
option for speed, I decided to commit sandboxing now. To also support
sandboxing when -n option wasn't specified, we need Casper daemon and its
services that are not available in FreeBSD yet.
- Limit file descriptors of a file specified by -r option or files specified
via -V option to CAP_READ only.
- If neither -r nor -V options were specified, we operate on /dev/bpf.
Limit its descriptor to CAP_READ and CAP_IOCTL plus limit allowed ioctls to
BIOCGSTATS only.
- Limit file descriptor of a file specified by -w option to CAP_SEEK and
CAP_WRITE.
- If either -C or -G options were specified, we open directory containing
destination file and we limit directory descriptor to CAP_CREATE, CAP_FCNTL,
CAP_FTRUNCATE, CAP_LOOKUP, CAP_SEEK and CAP_WRITE. Newly opened/created
files are limited to CAP_SEEK and CAP_WRITE only.
- Enter capability mode if -n option was specified and neither -z nor -V

Add MachineBasicBlock::addLiveIn().
This function adds a live-in physical register to an MBB and ensures
that it is copied to a virtual register immediately.
Pull in r185615 from llvm trunk:
Live-in copies go *after* EH_LABELs.
This will soon be tested by exception handling working at all.
Pull in r185617 from llvm trunk:
Simplify landing pad lowering.
Stop using the ISD::EXCEPTIONADDR and ISD::EHSELECTION when lowering
landing pad arguments. These nodes were previously legalized into
CopyFromReg nodes, but that never worked properly because the
CopyFromReg node weren't guaranteed to be scheduled at the top of the
basic block.
This meant the exception pointer and selector registers could be
clobbered before being copied to a virtual register.
This patch copies the two physical registers to virtual registers at
the beginning of the basic block, and lowers the landingpad instruction
directly to two CopyFromReg nodes reading the *virtual* registers. This
is safe because virtual registers don't get clobbered.
A future patch will remove the ISD::EXCEPTIONADDR and ISD::EHSELECTION
nodes.
Together, these changes fix llvm PR 16038 ('qt4 webcore file results in
"Bad machine code: Using an undefined physical register"'), and should
make it possible again to compile the www/qt4-webkit port again on the
i386 arch, without using a CPUTYPE=i686 or higher setting.
the stack in a leaf function that uses TLS.
The issue is, when using TLS, the function is no longer a leaf as it calls
__aeabi_read_tp. With statically linked programs this is not an issue as
it doesn't make use of the stack, however with dynamically linked
applications we enter rtld which does use the stack and makes assumptions
about it's alignment.
This is only a temporary fix until a better patch can be made and submitted
upstream.
- Reconnect with some minor modifications, in particular now selsocket()
internals are adapted to use sbintime units after recent'ish calloutng

-Add configure support for FreeBSD 10 and 11.
-Adapt a threading fix to gnu POSIX95 (which we don't use).
-Refer to a bug fix for the disabled vrptree support.
This is all useless in our current build but it is included
for convenience in case someone may want to re-package our
older gcc.

Make PrologEpilogInserter save/restore all callee saved registers in

__builtin_unwind_init() is an undocumented gcc intrinsic which has
this effect, and is used in libgcc_eh.
Goes part of the way toward fixing PR8541.
This obsoletes the ugly hack to libgcc's unwind code from r245272, and
should also work for other arches, so revert the hack too.
Parse_SetInput:
curFile->fname was using the buffer passed to it - which ReadMakefile frees.
This change makes the comment in ParseEOF about leaking curFile->fname true.
This is actually a fully functional build except:
* All internal shared libraries are static linked to make sure there
is no interference with ports (and to reduce build time).
* It does not have the python/perl/etc plugin or API support.
* By default, it installs as "svnlite" rather than "svn".
* If WITH_SVN added in make.conf, you get "svn".
* If WITHOUT_SVNLITE is in make.conf, this is completely disabled.
To be absolutely clear, this is not intended for any use other than
checking out freebsd source and committing, like we once did with cvs.
It should be usable for small scale local repositories that don't
need the python/perl plugin architecture.
