For Hexagon we want to be able to call functions during debugging, however currently lldb only supports this when there is JIT support.
Although emulation using IR interpretation is an alternative, it is currently limited in that it can't make function calls.

In this patch we have extended the IR interpreter so that it can execute a function call on the target using register manipulation.
To do this we need to handle the Call IR instruction, passing arguments to a new thread plan and collecting any return values to pass back into the IR interpreter.

The new thread plan is needed to call an alternative ABI interface of "ABI::PerpareTrivialCall()", allowing more detailed information about arguments and return values.

9 years ago[PPC64LE] More improvements to VSX swap optimization
Bill Schmidt [Mon, 13 Jul 2015 22:58:19 +0000 (22:58 +0000)]
[PPC64LE] More improvements to VSX swap optimization

This patch allows VSX swap optimization to succeed more frequently.
Specifically, it is concerned with common code sequences that occur
when copying a scalar floating-point value to a vector register.  This
patch currently handles cases where the floating-point value is
already in a register, but does not yet handle loads (such as via an
LXSDX scalar floating-point VSX load).  That will be dealt with later.

A typical case is when a scalar value comes in as a floating-point
parameter.  The value is copied into a virtual VSFRC register, and
then a sequence of SUBREG_TO_REG and/or COPY operations will convert
it to a full vector register of the class required by the context.  If
this vector register is then used as part of a lane-permuted
computation, the original scalar value will be in the wrong lane.  We
can fix this by adding a swap operation following any widening
SUBREG_TO_REG operation.  Additional COPY operations may be needed
around the swap operation in order to keep register assignment happy,
but these are pro forma operations that will be removed by coalescing.

If a scalar value is otherwise directly referenced in a computation
(such as by one of the many XS* vector-scalar operations), we
currently disable swap optimization.  These operations are
lane-sensitive by definition.  A MentionsPartialVR flag is added for
use in each swap table entry that mentions a scalar floating-point
register without having special handling defined.

A common idiom for PPC64LE is to convert a double-precision scalar to
a vector by performing a splat operation.  This ensures that the value
can be referenced as V[0], as it would be for big endian, whereas just
converting the scalar to a vector with a SUBREG_TO_REG operation
leaves this value only in V[1].  A doubleword splat operation is one
form of an XXPERMDI instruction, which takes one doubleword from a
first operand and another doubleword from a second operand, with a
two-bit selector operand indicating which doublewords are chosen.  In
the general case, an XXPERMDI can be permitted in a lane-swapped
region provided that it is properly transformed to select the
corresponding swapped values.  This transformation is to reverse the
order of the two input operands, and to reverse and complement the
bits of the selector operand (derivation left as an exercise to the
reader ;).

A new test case that exercises the scalar-to-vector and generalized
XXPERMDI transformations is added as CodeGen/PowerPC/swaps-le-5.ll.
The patch also requires a change to CodeGen/PowerPC/swaps-le-3.ll to
use CHECK-DAG instead of CHECK for two independent instructions that
now appear in reverse order.

There are two small unrelated changes that are added with this patch.
First, the XXSLDWI instruction was incorrectly omitted from the list
of lane-sensitive instructions; this is now fixed.  Second, I observed
that the same webs were being rejected over and over again for
different reasons.  Since it's sufficient to reject a web only once, I
added a check for this to speed up the compilation time slightly.

Remove unnecessary lines from the test in r242068.

This test case was breaking the hexagon elf bot.  The failing lines
were actually unnecessary as checking that the store still reads the
correct value demonstrates that everything is working fine now.

9 years agoReduce memory usage of ComputeEditDistance() by (almost) 50%
Nico Weber [Mon, 13 Jul 2015 21:33:21 +0000 (21:33 +0000)]
Reduce memory usage of ComputeEditDistance() by (almost) 50%

ComputeEditDistance() currently keeps two rows of the edit distance matrix in
memory.  That's unnecessary, one row plus one additional element are sufficient.
With this change, strings up to 64 chars can be processed without going to the
heap, compared to 32 chars previously.  (But the main motivation is that the
code gets a bit simpler.)

No intended behavior change.

9 years agoLoop idiom recognizer was replacing too many uses of popcount.
Pete Cooper [Mon, 13 Jul 2015 21:25:33 +0000 (21:25 +0000)]
Loop idiom recognizer was replacing too many uses of popcount.

When spotting that a loop can use ctpop, we were incorrectly replacing all uses of a value with a value derived from ctpop.

The bug here was exposed because we were replacing a use prior to the ctpop with the ctpop value and so we have a use before def, i.e., we changed

 %tobool.5 = icmp ne i32 %num, 0
 store i1 %tobool.5, i1* %ptr
 br i1 %tobool.5, label %for.body.lr.ph, label %for.end

to

 store i1 %1, i1* %ptr
 %0 = call i32 @llvm.ctpop.i32(i32 %num)
 %1 = icmp ne i32 %0, 0
 br i1 %1, label %for.body.lr.ph, label %for.end

Even if we inserted the ctpop so that it dominates the store here, that would still be incorrect.  The store doesn’t want the result of ctpop.

The fix is very simple, and involves replacing only the branch condition with the ctpop instead of all uses.

The outlined funclets call intrinsics which reference labels from the

cleanup at -O0, where Clang marks a definition as nounwind, and then
WinEHPrepare "discovers" that the landingpad is dead by accident and
