[mlir] replace LLVMIntegerType with built-in integer type

The LLVM dialect type system has been closed until now, i.e. did not support
types from other dialects inside containers. While this has had obvious
benefits of deriving from a common base class, it has led to some simple types
being almost identical with the built-in types, namely integer and floating
point types. This in turn has led to a lot of larger-scale complexity: simple
types must still be converted, numerous operations that correspond to LLVM IR
intrinsics are replicated to produce versions operating on either LLVM dialect
or built-in types leading to quasi-duplicate dialects, lowering to the LLVM
dialect is essentially required to be one-shot because of type conversion, etc.
In this light, it is reasonable to trade off some local complexity in the
internal implementation of LLVM dialect types for removing larger-scale system
complexity. Previous commits to the LLVM dialect type system have adapted the
API to support types from other dialects.

Replace LLVMIntegerType with the built-in IntegerType plus additional checks
that such types are signless (these are isolated in a utility function that
replaced `isa<LLVMType>` and in the parser). Temporarily keep the possibility
to parse `!llvm.i32` as a synonym for `i32`, but add a deprecation notice.

Andrzej Warzynski [Thu, 7 Jan 2021 09:08:54 +0000 (09:08 +0000)]
[flang][driver] Add support for `-c` and `-emit-obj`

This patch adds a frontend action for emitting object files. While Flang
does not support code-generation, this action remains a placeholder.
This patch simply provides glue-code to connect the compiler driver
with the appropriate frontend action.

The new action is triggered with the `-c` compiler driver flag, i.e.
`flang-new -c`. This is then translated to `flang-new -fc1 -emit-obj`,
so `-emit-obj` has to be marked as supported as well.

As code-generation is not available yet, `flang-new -c` results in a
driver error:
error: code-generation is not available yet
Hopefully this will help communicating the level of available
functionality within Flang.

The definition of `emit-obj` is updated so that it can be shared between
Clang and Flang. As the original definition was enclosed within a
Clang-specific TableGen `let` statement, it is extracted into a new `let`
statement. That felt like the cleanest option.

I also commented out `-triple` in Flang::ConstructJob and updated some
comments there. This is similar to https://reviews.llvm.org/D93027. I
wanted to make sure that it's clear that we can't support `-triple`
until we have code-generation. However, once code-generation is
available we _will need_ `-triple`.

As this patch adds `-emit-obj`, the emit-obj.f90 becomes irrelevant and
is deleted. Instead, phases.f90 is added to demonstrate that users can
control compilation phases (indeed, `-c` is a phase control flag).

Pedro Tammela [Wed, 16 Dec 2020 21:34:44 +0000 (21:34 +0000)]
[lldb/Lua] add support for multiline scripted breakpoints

1 - Partial Statements

The interpreter loop runs every line it receives, so partial
Lua statements are not being handled properly. This is a problem for
multiline breakpoint scripts since the interpreter loop, for this
particular case, is just an abstraction to a partially parsed function
body declaration.

This patch addresses this issue and as a side effect improves the
general Lua interpreter loop as well. It's now possible to write partial
statements in the 'script' command.

   (lldb) script
   >>>   do
   ..>   local a = 123
   ..>   print(a)
   ..>   end

The technique implemented is the same as the one employed by Lua's own REPL implementation.
Partial statements always errors out with the '<eof>' tag in the error

2 - CheckSyntax in Lua.h

In order to support (1), we need an API for just checking the syntax of string buffers.

3 - Multiline scripted breakpoints

Finally, with all the base features implemented this feature is
straightforward. The interpreter loop behaves exactly the same, the
difference is that it will aggregate all Lua statements into the body of
the breakpoint function. An explicit 'quit' statement is needed to exit the
interpreter loop.

   (lldb) breakpoint command add -s lua
   Enter your Lua command(s). Type 'quit' to end.
   The commands are compiled as the body of the following Lua function
   function (frame, bp_loc, ...) end

By emitting signposts we can examine this information in Instruments. I
recommend looking at Daniel's differential for why this is so powerful:

8 months ago[Support] Untie the llvm::Signpost interface from llvm::Timer
Jonas Devlieghere [Wed, 6 Jan 2021 22:35:07 +0000 (14:35 -0800)]
[Support] Untie the llvm::Signpost interface from llvm::Timer

Make llvm::Signpost more generic by untying from llvm::Timer. This
allows signposts to be used in a different context.

My motivation for doing this is being able to use signposts in LLDB.
