Andrea Di Biagio [Mon, 30 Jun 2014 17:14:21 +0000 (17:14 +0000)]
[X86] Add support for builtin to read performance monitoring counters.

This patch adds support for a new builtin instruction called
__builtin_ia32_rdpmc.

Builtin '__builtin_ia32_rdpmc' is defined as a 'GCC builtin'; on X86, it can
be used to read performance monitoring counters. It takes as input the index
of the performance counter to read, and returns the value of the specified
performance counter as a 64-bit number.

Calls to this new builtin will map to instruction RDPMC.
The index in input to the builtin call is moved to register %ECX. The result
of the builtin call is the value of the specified performance counter (RDPMC
would return that quantity in registers RDX:RAX).

This patch:
 - Adds builtin int_x86_rdpmc as a GCCBuiltin;
 - Adds a new x86 DAG node called 'RDPMC_DAG';
 - Teaches how to lower this new builtin;
 - Adds an ISel pattern to select instruction RDPMC;
 - Fixes the definition of instruction RDPMC adding %RAX and %RDX as
   implicit definitions, and adding %ECX as implicit use;
 - Adds a LLVM test to verify that the new builtin is correctly selected.

7 years ago[RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.
Lang Hames [Fri, 27 Jun 2014 20:20:57 +0000 (20:20 +0000)]
[RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.

This patch adds a "-verify" mode to the llvm-rtdyld utility. In verify mode,
llvm-rtdyld will test supplied expressions against the linked program images
that it creates in memory. This scheme can be used to verify the correctness
of the relocation logic applied by RuntimeDyld.

The expressions to test will be read out of files passed via the -check option
(there may be more than one of these). Expressions to check are extracted from
lines of the form:
# rtdyld-check: <expression>

This system is designed to fit the llvm-lit regression test workflow. It is
format and target agnostic, and supports verification of images linked for
remote targets. The expression language is defined in
llvm/include/llvm/RuntimeDyldChecker.h . Examples can be found in
test/ExecutionEngine/RuntimeDyld.

Chandler Carruth [Fri, 27 Jun 2014 11:23:44 +0000 (11:23 +0000)]
[x86] Begin a significant overhaul of how vector lowering is done in the
x86 backend.

This sketches out a new code path for vector lowering, hidden behind an
off-by-default flag while it is under development. The fundamental idea
behind the new code path is to aggressively break down the problem space
in ways that ease selecting the odd set of instructions available on
x86, and carefully avoid scalarizing code even when forced to use older
ISAs. Notably, this starts off restricting itself to SSE2 and implements
the complete vector shuffle and blend space for 128-bit vectors in SSE2
without scalarizing. The plan is to layer on top of this ISA extensions
where we can bail out of the complex SSE2 lowering and opt for
a cheaper, specialized instruction (or set of instructions). It also
needs to be generalized to AVX and AVX512 vector widths.

Currently, this does a decent but not perfect job for SSE2. There are
some specific shortcomings that I plan to address:
- We need a peephole combine to fold together shuffles where possible.
  There are cases where a previous shuffle could be modified slightly to
  arrange for elements to be in the correct position and a later shuffle
  eliminated. Doing this eagerly added quite a bit of complexity, and
  so my plan is to combine away these redundancies afterward.
- There are a lot more clever ways to use unpck and pack that need to be
  added. This is essential for real world shuffles as it turns out...

Once SSE2 is polished a bit I should be able to get interesting numbers
on performance improvements on benchmarks conducive to vectorization.
All of this will be off by default until it is functionally equivalent
of course.

7 years ago[RuntimeDyld, PowerPC] Fix/improve handling of TOC relocations
Ulrich Weigand [Fri, 27 Jun 2014 10:32:14 +0000 (10:32 +0000)]
[RuntimeDyld, PowerPC] Fix/improve handling of TOC relocations

Current PPC64 RuntimeDyld code to handle TOC relocations has two
problems:

- With recent linkers, in addition to the relocations that implicitly
  refer to the TOC base (R_PPC64_TOC*), you can now also use the .TOC.
  magic symbol with any other relocation to refer to the TOC base
  explicitly.  This isn't currently used much in ELFv1 code (although
  it could be), but it is essential in ELFv2 code.

- In a complex JIT environment with multiple modules, each module may
  have its own .toc section, and TOC relocations in one module must
  refer to *its own* TOC section.  The current findPPC64TOC implementation
  does not correctly implement this; in fact, it will always return the
  address of the first TOC section it finds anywhere.  (Note that at the
  time findPPC64TOC is called, we don't even *know* which module the
  relocation originally resided in, so it is not even possible to fix
  this routine as-is.)

This commit fixes both problems by handling TOC relocations earlier, in
processRelocationRef.  To do this, I've removed the findPPC64TOC routine
and replaced it by a new routine findPPC64TOCSection, which works
analogously to findOPDEntrySection in scanning the sections of the
ObjImage provided by its caller, processRelocationRef.  This solves the
issue of finding the correct TOC section associated with the current
module.

This makes it straightforward to implement both R_PPC64_TOC relocations,
and relocations explicitly refering to the .TOC. symbol, directly in
processRelocationRef.  There is now a new problem in implementing the
R_PPC64_TOC16* relocations, because those can now in theory involve
*three* different sections: the relocation may be applied in section A,
refer explicitly to a symbol in section B, and refer implicitly to the
TOC section C.  The final processing of the relocation thus may only
happen after all three of these sections have been assigned final
addresses.  There is currently no obvious means to implement this in
its general form with the common-code RuntimeDyld infrastructure.

Fortunately, ppc64 code usually makes no use of this most general form;
in fact, TOC16 relocations are only ever generated by LLVM for symbols
residing themselves in the TOC, which means "section B" == "section C"
in the above terminology.  This special case can easily be handled with
the current infrastructure, and that is what this patch does.
[ Unhandled cases result in an explicit error, unlike the current code
which silently returns the wrong TOC base address ... ]

This patch makes the JIT work on both BE and LE (ELFv2 requires
additional patches, of course), and allowed me to successfully run
complex JIT scenarios (via mesa/llvmpipe).
