counters for profiling, as in clang's ``-fprofile-instr-generate``.

Doing the instrumentation this way opens some doors in terms of

simple to experiment with alternate lowering strategies, and allows us

  %shl = shl <8 x i16> %A, %shamt
  ret <8 x i16> %shl

IR: Add missing tests for function-local metadata

Add assembly and bitcode tests that I neglected to add in r223564 (IR:
Disallow complicated function-local metadata) and r223574 (IR: Disallow
function-local metadata attachments).

Found a couple of bugs:

  - The error message for function-local attachments gave the wrong line
    number -- it indicated the next token (typically on the next line)
    instead of the token that started the attachment.  Fixed.

  - Metadata arguments of the form `!{i32 0, i32 %v}` (or with the
    arguments reversed) fired an assertion in `ValueEnumerator` in LLVM
    v3.5, so I suppose this never really worked.  I suppose this was
    "fixed" by r223564.

Before we crack 32-byte build vectors into smaller chunks (and then subsequently
glue them back together), we should look for the easy case where we can just load
all elements in a single op.

An example of the codegen change is:

From:

vmovss  16(%rdi), %xmm1
vmovups (%rdi), %xmm0
vinsertps       $16, 20(%rdi), %xmm1, %xmm1
vinsertps       $32, 24(%rdi), %xmm1, %xmm1
vinsertps       $48, 28(%rdi), %xmm1, %xmm1
vinsertf128     $1, %xmm1, %ymm0, %ymm0
retq

To:

vmovups (%rdi), %ymm0
retq

9 years agoUse 32-bit ebp for NaCl64 in a limited case: llvm.frameaddress.
Jan Wen Voung [Fri, 5 Dec 2014 20:55:53 +0000 (20:55 +0000)]
Use 32-bit ebp for NaCl64 in a limited case: llvm.frameaddress.

Summary:
Follow up to [x32] "Use ebp/esp as frame and stack pointer":
http://reviews.llvm.org/D4617

In that earlier patch, NaCl64 was made to always use rbp.
That's needed for most cases because rbp should hold a full
64-bit address within the NaCl sandbox so that load/stores
off of rbp don't require sandbox adjustment (zeroing the top
32-bits, then filling those by adding r15).

However, llvm.frameaddress returns a pointer and pointers
are 32-bit for NaCl64. In this case, use ebp instead, which
will make the register copy type check. A similar mechanism
may be needed for llvm.eh.return, but is not added in this change.

[X86] Improved lowering of packed vector shifts to vpsllq/vpsrlq.

SSE2/AVX non-constant packed shift instructions only use the lower 64-bit of
the shift count.

This patch teaches function 'getTargetVShiftNode' how to deal with shifts
where the shift count node is of type MVT::i64.

Before this patch, function 'getTargetVShiftNode' only knew how to deal with
shift count nodes of type MVT::i32. This forced the backend to wrongly
truncate the shift count to MVT::i32, and then zero-extend it back to MVT::i64.
