fb577b1049 Hide the whole JIT API behind #if USE_EMBEDDED_COMPILER 
Kind ugly, but at least the conditionals are used consistently now.

4641e2960f Move ExpressionActions::compileFunctions to ExpressionJIT.cpp. 
This means ExpressionJIT.h only has to expose one function.

6e05c5ace4 compilePrologue() isn't particularly useful after all. 
Basically the only thing it can do that compile() can't is create 'alloca'
instructions, which are only needed to get pointers to stack variables.
Given that dynamically-sized allocations aren't possible with this API,
such pointers are probably completely pointless (heh).

a1eb938ed2 Inline nullable number constants into compiled code. 
Also, protect against some segfaults during compilation by checking
correctness of the type returned by compile().

ccc895d162 Represent nullable types as pairs instead of pointers. 
Turns out LLVM has insertvalue & extractvalue for struct in registers. This is
faster than pointers because null checks are now subject to more optimizations.

979c4d959f Let jit-compilable functions deal with NULLs themselves. 
And provide a default implementation of compile() for nullable columns
that actually works and is consistent with execute().

c95f8a669f Throw in untyped versions of IFunction::{isCompilable,compile} 
IFunction inherits IFunctionBase for some reason despite not actually knowing
the types, so these two methods make no sense. The versions with DataTypes&
as an argument should be used instead.

3810173103 Remove IFunction::createResultColumn. 
Given that the list of supported types is hardcoded in
LLVMContext::Data::toNativeType, this method is redundant because
LLVMPreparedFunction can create a ColumnVector itself.

I honestly can't tell if they work. LLVM has surprisingly bad API documentation.

e96a5e8344 Implement JIT compilation, without a loop for now. 
It actually seems to work, so long as you only have one row that is. E.g.

    > select something(cast(number + 6 as Float64), cast(number + 2 as Float64)) from system.numbers limit 1';
    8

with this IR:

    define void @"something(CAST(plus(number, 6), 'Float64'), CAST(plus(number, 2), 'Float64'))"(void**, i8*, double*) {
    entry:
      %3 = load void*, void** %0
      %4 = bitcast void* %3 to double*
      %5 = load double, double* %4
      %6 = getelementptr void*, void** %0, i32 1
      %7 = load void*, void** %6
      %8 = bitcast void* %7 to double*
      %9 = load double, double* %8
      %10 = fadd double %5, %9
      store double %10, double* %2
      ret void
    }

b398ffbaba Map all number types to LLVM types. 
The example from the previous commit doesn't need a cast to Float64 anymore.
 2018-04-25 13:37:25 +03:00

851684de51 Add a JIT interface for row-wise default-nullable functions. 
Not actually implemented, though. It does print out some jit-compiled stuff,
but that's about it. For example, this query:

    select number from system.numbers where something(cast(number as Float64)) == 4

results in this on server's stderr:

    define double @"something(CAST(number, 'Float64'))"(void**, i8*, void*) {
    "something(CAST(number, 'Float64'))":
      ret double 1.234500e+04
    }

(and an exception, because that's what the non-jitted method does.)

As one may notice, this function neither reads the input (first argument;
tuple of arrays) nor writes the output (third argument; array), instead
returning some general nonsense.

In addition, `#if USE_EMBEDDED_COMPILER` doesn't work for some reason,
including LLVM headers requires -Wno-unused-parameter, this probably only
works on LLVM 5.0 due to rampant API instability, and I'm definitely
no expert on CMake. In short, there's still a long way to go.
