whitequark 49682d0159 Improve Python 3.7 compatibility. 
async is now a full (non-contextual) keyword.

There are two more instances:
   - artiq/frontend/artiq_client.py
   - artiq/devices/thorlabs_tcube/driver.py

It is not immediately clear how to fix those, so they are left for
later work.

David Nadlinger 2463e5667d compiler: Fix attribute writeback with skipped fields 
offset wasn't advanced for skipped fields previously,
leading to memory corruption/unaligned accesses at runtime.
 2018-08-14 13:34:32 +01:00
whitequark fab6e5cdff compiler: skip functional values in attribute writeback. 
Fixes #1088.

David Nadlinger 768b970deb Fixup 4359a437 (tuples of lists), add regression tests 2018-07-10 01:18:51 +01:00
David Nadlinger 4359a43732 compiler: Indirection status of TTuple depends on elements 
For instance, TTuple(TList(TInt32())) has indirections, while
TTuple(TInt32()) does not.

This fixes memory corruption with RPCs that return tuples of lists.

This fixes access violations on Windows that are present both with

whitequark ca254ec55e compiler: disallow op= on mutable lists only (fix #835). 
This only really applies to lists since those use fat pointers.
`x.y += z` is fine.
 2017-10-02 07:21:14 +00:00

whitequark ed2b10c5aa compiler: in codegen for delay(), round fp instead of truncating. 
Consider delay(8*us). It results in the following computation...
  >>> 8*1e-06/1e-09
  7999.999999999999
with the result promptly getting truncated to 7999.

Fixes #706.

whitequark 3a1fc729cf compiler: refactor type annotations recognizing in kernels. 
The new implementation is much more generic, more robust,

whitequark 7e886ddc89 transforms.inferencer: do not unnecessarily mutate typedtree. 
This caused the hash to change after every iteration of inference,

whitequark 4107938fd8 compiler.embedding: use attribute count in fixpoint condition. 
Before this commit, we had a hack where inferencing would run
one more time, in case we can still infer more attributes even
after all the type information is there. This doesn't work
if *that* round of inferencing brings even more code, e.g.
this is easy to trigger with context managers.

whitequark 3a1f14c16c compiler: fix overly strict constness analysis. 
Before this commit, the following code would fail to compile...
  obj.foo.bar = True
... if foo is marked kernel_invariant in obj, even if bar is not
marked as such in obj.foo.

 2016-12-05 05:04:26 +00:00
whitequark 4305903dde compiler: rein in overzealous cast monomorphization. 
This caused failures on e.g. "int32(var64a >> var64b)", where
the type of the argument is already fully known, but was unified
with the result of the cast anyway.

whitequark 35f4449ef2 inferencer: significantly improve the op-assignment diagnostic. 
Before this commit, it displayed incorrect output if an error

whitequark 5a79fcf9ba embedding: reimplement 373578bc properly. 
The core of the problem that 373578bc was attempting to solve is
that diagnostics sometimes should be chained; one way of chaining
is the loc.expanded_from feature, which handles macro-like expansion,
but another is providing context.

Before this commit, context was provided using an ad-hoc override
of a diagnostic engine, which did not work in cases where diagnostic
engine was not threaded through the call stack. This commit uses
the newly added pythonparser context feature to elegantly handle
the problem.

whitequark 8a908a7656 llvm_ir_generator: do not use 'coldcc' calling convention. 
First, this calling convention doesn't actually exist in OR1K
and trying to use it in Asserts build causes an UNREACHABLE.

Second, I tried to introduce it and it does not appear to produce
any measurable benefit: not only OR1K has a ton of CSRs but also
it is quite hard, if not realistically impossible, to produce
the kind of register pressure that would be relieved by sparing
a few more CSRs for our exception raising function calls, since
temporaries don't have to be preserved before a noreturn call
and spilling over ten registers across an exceptional edge
is not something that the code we care about would do.

Third, it produces measurable drawbacks: it inflates code size
of check:* functions by adding spills. Of course, this could be
alleviated by making __artiq_raise coldcc as well, but what's
the point anyway?

 2016-03-28 19:56:56 +00:00
whitequark 1d8b0d46bc compiler: mark FFI functions as ModRef=Ref using TBAA metadata. 
Fascinatingly, the fact that you can mark call instructions with
!tbaa metadata is completely undocumented. Regardless, it is true:
a !tbaa metadata for an "immutable" type will cause
AliasAnalysis::getModRefBehavior to return OnlyReadsMemory for that
call site.

Don't bother marking loads with TBAA yet since we already place
!load.invariant on them (which is as good as the TBAA "immutable"
flag) and after that we're limited by lack of !nonnull anyway.

Also, add TBAA analysis passes in our pipeline to actually engage it.
