whitequark 7b2da5294f compiler: add support for printing of bytes values (#714). 2017-06-09 07:10:48 +00:00
whitequark dba4e1a28b compiler: add support for bytes type and b"x" literals (#714). 2017-06-09 07:10:48 +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 31048f4b6a compiler: fix monomorphization of coerced integer literals.
Fixes #703.
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.
2017-03-02 16:15:37 +00:00
whitequark a79c3c2cff compiler.transforms: implement a typedtree printer. 2017-03-02 15:28:04 +00:00
whitequark 252cda6e7f compiler.llvm_ir_generator: fix string quoting. 2017-02-28 21:28:38 +00:00
whitequark d04e611232 firmware, compiler: rename rpc functions to be more consistent. 2017-02-25 14:12:58 +00:00
whitequark c39394b4d5 firmware: port the exception handling routines to Rust. 2017-02-04 08:21:07 +00:00
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.
2017-01-31 22:11:13 +00:00
whitequark ab71c9a0ba compiler: the len builtin is not polymorphic, coerce the result.
Fixes #659.

whitequark 57f54dbd12 llvm_ir_generator: recognize inline and forceinline flags. 2017-01-25 10:25:00 +00:00
whitequark f68e4ae519 compiler: rein in overzealous cast monomorphization. 2016-12-05 05:08:57 +00:00
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.

This helps LICM, among other things.

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.

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.

2016-04-05 00:48:41 +00:00
whitequark ad83b092fa llvm_ir_generator: change !{→unconditionally_}dereferenceable.
Since LLVM 3.8, !dereferenceable is weaker, so we introduce
!unconditionally_dereferenceable (http://reviews.llvm.org/D18738)
to regain its functionality.

whitequark 2c04979727 compiler: update for LLVM 3.7. 2016-03-31 11:23:47 +00:00
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?

whitequark 6f5332f892 compiler: allow flagging syscalls, providing information to optimizer.
This also fixes a crash in test_cache introduced in 1d8b0d46.
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.
2016-03-28 02:52:15 +00:00
whitequark 418f0a5234 compiler: mark loads of kernel constant attributes as load invariant.
Also, enable LICM, since it can take advantage of this.

2016-03-28 00:05:57 +00:00
whitequark e75ad3d1aa compiler: extract runtime checks into separate cold functions.
This reduces register pressure as well as function size, which
favorably affects the inliner.
2016-03-27 01:02:15 +00:00
whitequark 20ad7629ac llvm_ir_generator: generate code more amenable to LLVM's GlobalOpt.
This exposes almost all embedded methods to inlining, with massive

whitequark 81427af506 Remove selective attribute writeback; always synchronize all attributes.
The reasons are:
  1. Shadow memory manipulation added ~12 instructions to TTLOut.pulse
     (without inlining), and it's already barely fast enough.
  2. More importantly, code such as self.ts[1] did not trigger
     attribute writeback, and there seems to be no easy way to fix
     that.

whitequark 9ed6b54249 transforms.cfg_simplifier: remove.
Specifically, the following idiom broke our CFGSimplifier:

b1:

b2:

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.
