of the buffer returned by fgetln isn't really safe, so switch to using
getline() instead.

GCC expands the pointer type in this conditional expression even for
template types _Up that are not arrays. This raises an error when
std::decay<> is used with reference types (as is done in LLVM's

The noted argument is wrong - if it's already been deleted then the id we

Because we don't track deletions to the ruleset, working it out is

Instead, if we have already added the rule treat it as a non-op.
This is a valid use case because we might receive a burst of messages
in the downstream application for the same address and process them

[clang] Fix some clang->llvm type cache invalidation issues
Take the following as an example
struct z {
z (*p)();
};
z f();
When we attempt to get the LLVM type of f, we recurse into z. z itself
has a function pointer with the same type as f. Given the recursion,
Clang simply treats z::p as a pointer to an empty struct `{}*`. The
LLVM type of f is as expected. So we have two different potential
LLVM types for a given Clang type. If we store one of those into the
cache, when we access the cache with a different context (e.g. we
are/aren't recursing on z) we may get an incorrect result. There is some
attempt to clear the cache in these cases, but it doesn't seem to handle
all cases.
This change makes it so we only use the cache when we are not in any
sort of function context, i.e. `noRecordsBeingLaidOut() &&
FunctionsBeingProcessed.empty()`, which are the cases where we may
decide to choose a different LLVM type for a given Clang type. LLVM
types for builtin types are never recursive so they're always ok.
This allows us to clear the type cache less often (as seen with the
removal of one of the calls to `TypeCache.clear()`). We
still need to clear it when we use a placeholder type then replace it
later with the final type and other dependent types need to be
recalculated.
I've added a check that the cached type matches what we compute. It
triggered in this test case without the fix. It's currently not
check-clang clean so it's not on by default for something like expensive
checks builds.
This change uncovered another issue where the LLVM types for an argument
and its local temporary don't match. For example in type-cache-3, when
expanding z::dc's argument into a temporary alloca, we ConvertType() the
type of z::p which is `void ({}*)*`, which doesn't match the alloca GEP
type of `{}*`.
No noticeable compile time changes:

In the msg and shm tests, if the child exited before the parent
entered sigsuspend(), the test would hang and time out. This was
also a problem in the sem test, but the misuse of atf_tc_pass()
masked it. Adding a short sleep before the sigsuspend() calls made
the hang 100% reliable. With the same sleep in the new version,
the test passes reliably.
Remove calls to atf_tc_pass(). The call in the sem test broke the test
by exiting prematurely, after only one child out of five had finished.
The other two were harmless but unhelpful.
Reduce a one-second sleep to a more reasonable duration so I can quickly
run many iterations of the test.
Where feasible, assert that wait() returns the child PID. While I'm here,
use the more succinct ATF_REQUIRE* instead of if/atf_tc_fail/else.
Flush stdout before forking to avoid double-flush.
Use errx() when errno is irrelevant.
Don't use ATF_REQUIRE* in children. Apparently, the output doesn't
get saved. The exit status works, so it fails correctly, but silently.

Insert padding in __cxa_exception struct for compatibility
Similar to https://github.com/llvm/llvm-project/commit/f2a436058fcb, the
addition of __attribute__((__aligned__)) to _Unwind_Exception (in commit
b9616964) causes implicit padding to be inserted before the unwindHeader
field in __cxa_exception.
Applications attempt to get at the earlier fields in __cxa_exception, so
preserve the same negative offsets in __cxa_exception, by moving the
padding to the beginning of the struct.
The assumption here is that if the ABI is not aware of the padding
before unwindHeader and put the referenceCount/primaryException in
there, no padding should exist before unwindHeader.
This should make libreoffice's custom exception handling mechanisms work
correctly, even if it was built against an older cxxabi.h/unwind.h pair.

MFC: immediately
hostapd calls pcap_next(3) to read the next packet off the wlan interface.
pcap_next() returns a pointer to the packet header but does not indicate
success or failure. Unfortunately this results in an infinite loop (100%
CPU) when the wlan device disappears, i.e. when a USB wlan device is
manually removed or a USB error results in the device removal. However
pcap_next_ex(3) does return success or failure. To resolve this we use
pcap_next_ex(), forcing hostapd to exit when the error is encountered.
An error message is printed to syslog or stderr when debugging (-d flag)
is enabled. Unfortunately wpa_printf() only works when debugging is enabled.

This fixes runtime of most notably pcre libraries (currently patched in ports),

In contrast to Linux it does not provide entries which can be readlinked

on top of procfs not being mounted by default to begin with.

This register set contains the values of the fsbase and gsbase
registers. Note that these registers can already be controlled
individually via ptrace(2) via MD operations, so the main reason for
adding this is to include these register values in core dumps. In
particular, this will enable looking up the value of TLS variables
from core dumps in gdb.
The value of NT_X86_SEGBASES was chosen to match the value of
NT_386_TLS on Linux. The notes serve similar purposes, but FreeBSD
will never dump a note equivalent to NT_386_TLS (which dumps a single
segment descriptor rather than a pair of addresses) and picking a
currently-unused value in the NT_X86_* range could result in a future
conflict.

Merge commit b9ca73e1a8fd from llvm git (by Stephen Tozer):
[DebugInfo] Correctly handle arrays with 0-width elements in GEP salvaging
Fixes an issue where GEP salvaging did not properly account for GEP
instructions which stepped over array elements of width 0 (effectively a
no-op). This unnecessarily produced long expressions by appending
`... + (x * 0)` and potentially extended the number of SSA values used
in the dbg.value. This also erroneously triggered an assert in the
salvage function that the element width would be strictly positive.
These issues are resolved by simply ignoring these useless operands.
