David Nadlinger 611bcc4db4 compiler: Cache expensive target data layout queries 
On one typical experiment, this shaves about 3 seconds (~25%)
off the overall kernel compilation time.

GitHub: Closes #1370.
 2019-10-28 11:09:25 +00:00
David Nadlinger 5d7f22ffa4 compiler: Remove provision for unused four-parameter llptr_to_var() form [nfc] 
`var_type` was presumably intended to convert to a target type,
but wasn't actually acted on in the function body (nor was it
used anywhere in the codebase).
 2019-10-28 11:02:46 +00:00

David Nadlinger f9af058b96 compiler: Quote tuples as TTuple values 
Previously, they would end up being TInstances,
rendering them useless.

whitequark d6eb2b023a compiler: monomorphize casts first, but more carefully. 
This reverts 425cd7851, which broke the use of casts to define
integer width.

Instead of it, two steps are taken:
  * First, literals are monomorphized, leading to predictable result.
  * Second, casts are monomorphized, in a top-bottom way. I.e.
    consider the expression `int64(round(x))`. If round() was visited
    first, the intermediate precision would be 32-bit, which is
    clearly undesirable. Therefore, contextual rules should take
    priority over non-contextual ones.

Fixes #1252.
 2019-02-07 06:24:32 +00:00
whitequark 425cd7851e compiler: first monomorphize ints, then casts. 
Fixes #1242.
 2019-01-12 13:40:12 +00:00
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.

whitequark 21a0f26cd1 compiler: do not emit nonstandard !unconditionally* LLVM metadata. 
This metadata was added by an LLVM patch that was removed because
it was unsound.
 2018-05-19 16:58:03 +00:00

whitequark a0a2650fca compiler: do not use invoke for calls to nounwind ffi functions. 
Otherwise, declarations such as:

trip an LLVM assert because the invoke instruction and the !tbaa
metadata are no longer compatible since LLVM 4.0.

 2017-07-01 18:59:07 +00:00
whitequark ad2ee714c2 compiler: do not permit iterating str values. 
This currently breaks badly on UTF-8, and doesn't even return
a value of a correct type.

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.

 2017-04-12 04:11:47 +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 fd8b11532f compiler, firmware: use Pascal strings everywhere. 
This removes a large amount of very ugly code, and also simplifies
the compiler and runtime.
 2017-02-03 11:53:27 +00:00
whitequark ee1b2fa3ea compiler: swap the order of ptr/len fields in lists. 
This is to make them match the Rust slices.
Once the cslice crate becomes #![no_std] we'll also use its (tidier)
conversion functions.

whitequark 218720cfa7 Revert "compiler: rein in overzealous cast monomorphization." 
This reverts commit 4305903dde.

This broke the monomorphizer/round.py test.
 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.
 2016-12-05 04:38:25 +00:00
whitequark 68de724554 compiler: monomorphize int64(round(x)) to not lose precision. 
This applies to any expression with an indeterminate integer type
cast to int64(), not just round().
 2016-12-02 15:02:44 +00:00
whitequark 55ea68da7f compiler: unbreak casts to int32/int64. 2016-11-21 14:20:28 +00:00
whitequark 35f4449ef2 inferencer: significantly improve the op-assignment diagnostic. 
Before this commit, it displayed incorrect output if an error
appeared on 2nd run and beyond, and displayed messages for trying
to do "num32 -= num64" that made very little sense.

whitequark d3ee858d16 llvm_ir_generator: use !{→unconditionally.}invariant.load metadata. 
This helps LICM, among other things.
 2016-11-12 04:08:58 +00:00
David Nadlinger bfbdba9205 compiler: Emit all-kernel_invariant objects as LLVM constants 
This enables constant propagation optimisations, as verified by
the included test case. This is only a first stop-gap measure, though;
we should support optimisation based on kernel invariants on a more
fine-grained level.

This reverts commit fee75bd50f.

LLVM does not have lround as a libcall and this inhibits LICM.

David Nadlinger 6e77f65d50 compiler: Clarify recv_rpc value names and documentation [nfc] 
Previously, the phi emitted for the pointer parameter to recv_rpc was –
rather confusingly – called "size", and the pseudo-code in the comment
had bit-rotted.
