whitequark 79d020dd3a transforms.artiq_ir_generator: handle terminated try body. 2015-12-31 22:36:25 +08:00
whitequark 8aa34ee952 compiler: don't require exceptions to inherit ARTIQException. 2015-12-31 21:54:54 +08:00
whitequark 0b69e488e6 transforms.llvm_ir_generator: compare exn typeinfo using strcmp.
This is necessary to correctly catch exceptions from RPCs.
2015-12-31 19:53:28 +08:00
whitequark 9ed6b54249 transforms.cfg_simplifier: remove.
Specifically, the following idiom broke our CFGSimplifier:

b1:
  branch_if %cond, %b2, %b3
b2:
  branch %b3
b3:
  %v = phi [ %b2 => 0, %b3 => 1 ]

This is very annoying to properly handle in general case, and also
this (specifically %b2) is exactly what broke LocalAccessValidator
in the first place. So, remove CFGSimplifier altogether.

Instead, teach LocalAccessValidator how to look through predecessors
in order to get a location.

whitequark 82b470891f transforms.interleaver: handle function calls (as atomic so far).
This commit solves issue #2 described in 50e7b44; a function call
is now a valid decomposition for a delay instruction, and this
metadata is propagated when the interleaver converts delays.

However, the interleaver does not yet detect that a called function
is compound, i.e. it is not correct.
2015-11-21 03:34:24 +08:00
whitequark 57dd163d37 transforms.artiq_ir_generator: fix decomposition of explicit delay_mu(). 2015-11-21 03:27:06 +08:00
whitequark cb3b811fd7 compiler: maintain both the IR and iodelay forms of delay expressions.
After this commit, the delay instruction (again) does not generate
any LLVM IR: all heavy lifting is relegated to the delay and delay_mu
intrinsics. When the interleave transform needs to adjust the global
timeline, it synthesizes a delay_mu intrinsnic. This way,
the interleave transformation becomes composable, as the input and
the output IR invariants are the same.

Also, code generation is adjusted so that a basic block is split off
not only after a delay call, but also before one; otherwise, e.g.,
code immediately at the beginning of a `with parallel:` branch
would have no choice but to execute after another branch has already
advanced the timeline.

This takes care of issue #1 described in 50e7b44 and is a step
to solving issue #2.
2015-11-21 03:22:47 +08:00
whitequark 50e7b44d04 compiler: actually implement interleaving correctly (calls are still broken).
The previous implementation was completely wrong: it always advanced
the global timeline by the same amount as the non-interleaved basic
block did.

The new implementation only advances the global timeline by
the difference between its current time and the virtual time of
the branch, which requires it to adjust the delay instructions.

Previously, the delay expression was present in the IR twice: once
as the iodelay.Expr transformation-visible form, and once as regular
IR instructions, with the latter form being passed to the delay_mu
builtin and advancing the runtime timeline.

As a result of this change, this strategy is no longer valid:
we can meaningfully mutate the iodelay.Expr form but not the IR
instruction form. Thus, IR instructions are no longer generated for
delay expressions, and the LLVM lowering pass now has to lower
the iodelay.Expr objects as well.

This works OK for flat `with parallel:` expressions, but breaks down
outside of `with parallel:` or when calls are present. The reasons
it breaks down are as follows:

  * Outside of `with parallel:`, delay() and delay_mu() must accept
    any expression, but iodelay.Expr's are not nearly expressive
    enough. So, the IR instruction form must actually be kept as well.

  * A delay instruction is currently inserted after a call to
    a user-defined function; this delay instruction introduces
    a point where basic block reordering is possible as well as
    provides delay information. However, the callee knows nothing
    about the context in which it is called, which means that
    the runtime timeline is advanced twice. So, a new terminator
    instruction must be added that combines the properties of delay
    and call instructions (and another for delay and invoke as well).
