whitequark 98454e9bda runtime: remove unnecessary dcache flush. 
Data cache is write-through, so sending data to DMA doesn't need
a flush.

whitequark 218046d96c artiq_devtool: fix an infinite loop on network error. 2017-03-04 09:40:22 +00:00
whitequark 924ae73000 firmware: fix DMA trace alignment and flush caches. 2017-03-04 09:40:22 +00:00
whitequark 30ac42de3f ksupport: fix an exception safety issue. 
Raising from inside a recv! will never send an acknowledgement.

Sebastien Bourdeauducq 1e6a33b586 rtio: handle input timeout in gateware 
The information passed by the runtime will be used by the DRTIO core
to poll the remote side appropriately.

whitequark 4f94709e9f firmware: move packet dumps to the DEBUG log level. 2017-03-03 06:11:35 +00:00
whitequark e8c093deb3 Allow changing runtime log level without recompilation. 
This shouldn't affect performance much, as the log crate guards
every log statement with a branch, adding just two instructions.

whitequark 86dea869b3 compiler.types: add missing TTuple.__hash__ implementation. 2017-03-03 03:27:49 +00:00
whitequark 7e886ddc89 transforms.inferencer: do not unnecessarily mutate typedtree. 
This caused the hash to change after every iteration of inference,
if the result of any coercion was an integer of indefinite width.

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 88bf7d2233 firmware: specialize protocol read/write functions. 
Before this commit, proto::io::{read,write}_* functions were taking
a &mut {Read,Write}. This means a lot of virtual dispatch.
After this commit, all these functions are specialized for
the specific IO trait.

This could be achieved with just changing the signature from
  fn read_x(reader: &mut Read)
to
  fn read_x<R: Read>(reader: &mut R)
but the functions were also grouped into ReadExt and WriteExt
traits as a refactoring.

Initially, it was expected that the generic traits from
the byteorder crate could be used, but they require endianness
to be specified on every call and thus aren't very ergonomic.
They also lack the equivalent to our read_string and read_bytes.

Thus, it seems fine to just define a slightly different extension
trait.

This also optimized the test_rpc_timing test: 1.7ms→1.2ms.

whitequark 3a1f14c16c compiler: fix overly strict constness analysis. 
Before this commit, the following code would fail to compile...
  obj.foo.bar = True

marked as such in obj.foo.
