[PeepholeOptimizer] Advanced rewriting of copies to avoid cross register banks
copies.

This patch extends the peephole optimization introduced in r190713 to produce
register-coalescer friendly copies when possible.

This extension taught the existing cross-bank copy optimization how to deal
with the instructions that generate cross-bank copies, i.e., insert_subreg,
extract_subreg, reg_sequence, and subreg_to_reg.
E.g.
b = insert_subreg e, A, sub0 <-- cross-bank copy
...
C = copy b.sub0 <-- cross-bank copy

Would produce the following code:
b = insert_subreg e, A, sub0 <-- cross-bank copy
...
C = copy A <-- same-bank copy

This patch also introduces a new helper class for that: ValueTracker.
This class implements the logic to look through the copy related instructions
and get the related source.

For now, the advanced rewriting is disabled by default as we are lacking the
semantic on target specific instructions to catch the motivating examples.

This situation does bad things when inlined, so I've fixed Clang not to
produce inlinable call sites without locations when the caller has debug
info (in the one case where I could find that this occurred). This
updates the PR20038 test case to be what clang now produces, and readds
the assertion that had to be removed due to this bug.

I've also beefed up the debug info verifier to help diagnose these
issues in the future, and I hope to add checks to the inliner to just
assert-fail if it encounters this situation. If, in the future, we
decide we have to cope with this situation, the right thing to do is
probably to just remove all the DebugLocs from the inlined instructions.

9 years agoSuppress inlining when the block address is taken
Gerolf Hoflehner [Tue, 1 Jul 2014 00:19:34 +0000 (00:19 +0000)]
Suppress inlining when the block address is taken

Inlining functions with block addresses can cause many problem and requires a
rich infrastructure to support including escape analysis.  At this point the
safest approach to address these problems is by blocking inlining from
happening.

Background:
There have been reports on Ruby segmentation faults triggered by inlining
functions with block addresses like

//Ruby code snippet
vm_exec_core() {
    finish_insn_seq_0 = &&INSN_LABEL_finish;
    INSN_LABEL_finish:
      ;
}

This kind of scenario can also happen when LLVM picks a subset of blocks for
inlining, which is the case with the actual code in the Ruby environment.

LLVM suppresses inlining for such functions when there is an indirect branch.
The attached patch does so even when there is no indirect branch.  Note that
user code like above would not make much sense: using the global for jumping
across function boundaries would be illegal.

Why was there a segfault:

In the snipped above the block with the label is recognized as dead So it is
eliminated. Instead of a block address the cloner stores a constant (sic!) into
the global resulting in the segfault (when the global is used in a goto).

Why had it worked in the past then:

By luck. In older versions vm_exec_core was also inlined but the label address
used was the block label address in vm_exec_core.  So the global jump ended up
in the original function rather than in the caller which accidentally happened
to work.

Test case ./tools/clang/test/CodeGen/indirect-goto.c will fail as a result
of this commit.

9 years ago[X86] Add support for builtin to read performance monitoring counters.
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.

debug builds, so we shouldn't need to do anything ourselves.

Before this change, it was possible to a Debug build without assertions
(aka Debug-Asserts in the autoconf system) by configuring with
-DLLVM_ENABLE_ASSERTIONS=OFF, but this configuration isn't very useful.
