whitequark bb64992395 compiler: remove dead code. 2017-04-21 18:38:43 +00:00
whitequark c5d7445973 compiler: reject reachable implicit return if not returning TNone. 
Fixes #718.
 2017-04-21 18:11:14 +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.
 2017-04-21 17:36:44 +00:00
whitequark a820ae98cf ksupport: avoid allocations on I/O error paths. 
Fixes #715.

Fixes #716.
 2017-04-21 16:46:40 +00:00
whitequark 726ee7370a runtime: update smoltcp. 
This brings in correct TIME-WAIT handling. Fixes #722.
 2017-04-21 16:08:04 +00:00
whitequark 0e68eaa879 runtime: print a heap dump on out-of-memory condition. 2017-04-21 14:48:10 +00:00
whitequark fd994ceef3 DMA: various fixes to bring tests in line. 2017-04-20 20:05:03 +00:00
whitequark d383145752 conda: use GIT_FULL_HASH rather than GIT_DESCRIBE_HASH. 2017-04-20 16:58:38 +00:00
whitequark c9b20a1765 Commit missing parts of 0d0ddf2e. 2017-04-20 16:53:16 +00:00
whitequark 0d0ddf2e58 conda: limit git hashes in build numbers to 8 chars exactly. 
Before this commit, a nasty edge case was possible where repositories
on different builders have had different sets of objects fetched
into them, and so git-describe selected different lengths for
abbreviating hashes.

 2017-04-19 10:59:12 +08:00
whitequark 41c4de4556 DMA: add API for a much faster replay using handles. 2017-04-18 08:20:12 +00:00
whitequark c6e8d5c901 runtime: allow setting UART log level explicitly. 
This is way more convenient than commenting out parts
of session.rs when debugging.
 2017-04-15 08:27:18 +00:00
whitequark 0531dc45c3 DMA: erase trace before re-recording it. 
Or we could needlessly OOM replacing a large trace.
 2017-04-15 07:48:02 +00:00
whitequark 9dfe9c1248 DMA: improve recording performance. 
This commit moves DMA serialization code to the kernel CPU
(to cope with the existence of rtio_output_wide) and batches
the resulting sequences. This results in less data being transferred
between kernel and comms CPUs (24 octets with one pointer before,
18 octets with no pointers now, for the common case of rtio_output),
but most importantly reduces cache flushes, which now happen
once per 64k octets.

On average, it now takes about 15us to record a single RTIO event
in a DMA trace.

Fixes #712.

whitequark 0b9601f12d artiq_devtool: more robust defaults. 2017-04-13 08:26:48 +00:00
whitequark 3a1fc729cf compiler: refactor type annotations recognizing in kernels. 
The new implementation is much more generic, more robust,
and shares code with the same for syscalls as well as RPCs.

Fixes #713.
