Manuel Klimek 7a95ce4399 Make clang-format work in emacs buffers with unicode characters.
Emacs functions by default use character positions; convert characters
to offsets when handing parameters to clang-format and convert byte
offsets we get from clang-format back to character positions.
Reworked the code a bit so the 0-based to 1-based offset calculations
are done in the same place where we do the multi-byte to offset mapping.

Chandler Carruth 93756cff07 Suppress the newly added Clang warning for the inaccessible base in this
test. Do that after we suppress the warnings for unknown pragmas as this
warning flag is quite new in Clang and so old Clang's would warn all the
time on this file.

Chandler Carruth ad34d91343 [PM] Relax asserts and always try to reconstruct loop simplify form when
we can while splitting critical edges.

The only code which called this and didn't require simplified loops to
be preserved is polly, and the code behaves correctly there anyways.
Without this change, it becomes really hard to share this code with the
new pass manager where things like preserving loop simplify form don't
make any sense.

If anyone discovers this code behaving incorrectly, what it *should* be
testing for is whether the loops it needs to be in simplified form are
in fact in that form. It should always be trying to preserve that form
when it exists.

Erik Eckstein 76cb53a839 SLPVectorizer: limit the number of alias checks to reduce the runtime.
In case of blocks with many memory-accessing instructions, alias checking can take lot of time
(because calculating the memory dependencies has quadratic complexity).
I chose a limit which resulted in no changes when running the benchmarks.

David Majnemer 2dc8146643 Sema: Variable definitions cannot be __attribute__((alias))
Things that are OK:
  extern int var1 __attribute((alias("v1")));
  static int var2 __attribute((alias("v2")));

Things that are not OK:
  int var3 __attribute((alias("v3")));
  extern int var4 __attribute((alias("v4"))) = 4;

We choose to accpet:
  struct S { static int var5 __attribute((alias("v5"))); };

  This code causes assertion failues in GCC 4.8 and ICC 13.0.1, we have
  no reason to reject it.

This partially fixes PR22217.

Hal Finkel c3168129af [PowerPC] Minor correction to r226432
We don't need to exclude patchpoints from the implicit r2 dependence in
FastISel because it is added as an implicit operand and, thus, should not
confuse that StackMap code.

Hal Finkel af51993ee1 [PowerPC] Add r2 as an operand for all calls under both PPC64 ELF V1 and V2
Our PPC64 ELF V2 call lowering logic added r2 as an operand to all direct call
instructions in order to represent the dependency on the TOC base pointer
value. Restricting this to ELF V2, however, does not seem to make sense: calls
under ELF V1 have the same dependence, and indirect calls have an r2 dependence
just as direct ones. Make sure the dependence is noted for all calls under both
ELF V1 and ELF V2.

Chandler Carruth 78ae1c92ca [multilib] Teach Polly's CMake to use the libdir suffix variable. This
lets 'ninja check-polly' pass for me with a lib64 build of LLVM.

I've not updated the standalone side as I don't use it and don't have an
easy way to test any changes I've made there. I mostly wanted to be able
to actually run Polly's tests when I update its use of LLVM's APIs
during my refactorings on the (very unlikely) off chance that I make
a change which compiles but does the wrong thing.

Daniel Sanders 0cb9dc6e68 [mips] Make whitespace in disassembler tests more consistent. NFC.
The tests for the ISA's should now be approximately diffable. That is, the
output of 'diff valid-mips1.txt valid-mips2.txt' should be emit the lines
for instructions that were added/removed to/from MIPS-I by MIPS-II. This
doesn't work perfectly at the moment due to ordering differences but it
should be close.

Hal Finkel 58884f9fe6 [PowerPC] Don't hard-code R2 as register when processing TOC relocations
Instructions that have high-order TOC relocations always carry R2 as their base
register, so it does not matter whether we take the register from the
instruction or just hard-code it in PPCAsmPrinter. In the future, however, we
might want to apply these relocations to instructions using a different
register, so taking the register from the instruction is a better thing to do.
No change in functionality here, however.

Hal Finkel f81b6dd7a2 [PowerPC] Initial PPC64 calling-convention changes for fastcc
The default calling convention specified by the PPC64 ELF (V1 and V2) ABI is
designed to work with both prototyped and non-prototyped/varargs functions. As
a result, GPRs and stack space are allocated for every argument, even those
that are passed in floating-point or vector registers.

GlobalOpt::OptimizeFunctions will transform local non-varargs functions (that
do not have their address taken) to use the 'fast' calling convention.

When functions are using the 'fast' calling convention, don't allocate GPRs for
arguments passed in other types of registers, and don't allocate stack space for
arguments passed in registers. Other changes for the fast calling convention
may be added in the future.
