PowerPC: CTR shouldn't fire if a TLS call is in the loop
Determining the address of a TLS variable results in a function call in
certain TLS models. This means that a simple ICmpInst might actually
result in invalidating the CTR register.
In such cases, do not attempt to rely on the CTR register for loop
optimization purposes.
This fixes PR22034.
Differential Revision: http://reviews.llvm.org/D6786
This fixes a "Invalid PPC CTR loop" error when compiling parts of libc
for PowerPC-32.
[PowerPC] Replace foul hackery with real calls to __tls_get_addr
My original support for the general dynamic and local dynamic TLS
models contained some fairly obtuse hacks to generate calls to
__tls_get_addr when lowering a TargetGlobalAddress. Rather than
generating real calls, special GET_TLS_ADDR nodes were used to wrap
the calls and only reveal them at assembly time. I attempted to
provide correct parameter and return values by chaining CopyToReg and
CopyFromReg nodes onto the GET_TLS_ADDR nodes, but this was also not
fully correct. Problems were seen with two back-to-back stores to TLS
variables, where the call sequences ended up overlapping with unhappy
results. Additionally, since these weren't real calls, the proper
register side effects of a call were not recorded, so clobbered values
were kept live across the calls.
The proper thing to do is to lower these into calls in the first
place. This is relatively straightforward; see the changes to
PPCTargetLowering::LowerGlobalTLSAddress() in PPCISelLowering.cpp.
The changes here are standard call lowering, except that we need to
track the fact that these calls will require a relocation. This is
done by adding a machine operand flag of MO_TLSLD or MO_TLSGD to the
TargetGlobalAddress operand that appears earlier in the sequence.
The calls to LowerCallTo() eventually find their way to
LowerCall_64SVR4() or LowerCall_32SVR4(), which call FinishCall(),
which calls PrepareCall(). In PrepareCall(), we detect the calls to
__tls_get_addr and immediately snag the TargetGlobalTLSAddress with
the annotated relocation information. This becomes an extra operand
on the call following the callee, which is expected for nodes of type
tlscall. We change the call opcode to CALL_TLS for this case. Back
in FinishCall(), we change it again to CALL_NOP_TLS for 64-bit only,
since we require a TOC-restore nop following the call for the 64-bit
ABIs.
During selection, patterns in PPCInstrInfo.td and PPCInstr64Bit.td
convert the CALL_TLS nodes into BL_TLS nodes, and convert the
CALL_NOP_TLS nodes into BL8_NOP_TLS nodes. This replaces the code
removed from PPCAsmPrinter.cpp, as the BL_TLS or BL8_NOP_TLS
nodes can now be emitted normally using their patterns and the
associated printTLSCall print method.
Finally, as a result of these changes, all references to get-tls-addr
in its various guises are no longer used, so they have been removed.
There are existing TLS tests to verify the changes haven't messed
anything up). I've added one new test that verifies that the problem
with the original code has been fixed.
This fixes a fatal "Bad machine code" error when compiling parts of
libgomp for 32-bit PowerPC.

Totally forget deallocated SDNodes in SDDbgInfo.
What would happen before that commit is that the SDDbgValues associated with
a deallocated SDNode would be marked Invalidated, but SDDbgInfo would keep
a map entry keyed by the SDNode pointer pointing to this list of invalidated
SDDbgNodes. As the memory gets reused, the list might get wrongly associated
with another new SDNode. As the SDDbgValues are cloned when they are transfered,
this can lead to an exponential number of SDDbgValues being produced during
DAGCombine like in http://llvm.org/bugs/show_bug.cgi?id=20893
Note that the previous behavior wasn't really buggy as the invalidation made

- Omit the pipe2_nosigpipe testcase on FreeBSD (FreeBSD doesn't have
O_NOSIGPIPE).
- Convert "fcntl(n, F_CLOSEM)" to "closefrom(n)".
- Save and restore the resource limit on the number of files (RLIMIT_NOFILE).

the ELF file's byte order is not the native byte order. The
bug is that the variables holding the name and description size
are used (natively) after having been byte-swapped. The fix is
to calculate sz from them just prior to byte-swapping.

running ctfmerge on its objects, libelf asserts as it expects
.note sections to be 4-byte aligned. Change that expectation.

- Add missing #include sys/stat.h for mkdir(2)
- Omit the fchroot(2) tests because the support is not present on FreeBSD

- Mark the signo variable for the signal handle __unused
- Use limits.h instead of sys/syslimits.h (the latter does not
exist on FreeBSD)

- mcontext_t on FreeBSD doesn't have a __gregs field (it's split out on FreeBSD
into separate fields). In order to avoid muddying the test code with MD code,
the debugging trace info has not been implemented
- FreeBSD does not implement the si_stime and si_utime fields in siginfo_t, so
omit the debugging code that dumps the values
- sys/inttypes.h doesn't exist on FreeBSD

It is required for use with newer g++49
