Sebastien Bourdeauducq 6011444789 gui: log error and bail out on artiq_gui.pyon write failure (#360) 2016-03-30 01:45:00 +08:00
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 586022023b llvm_ir_generator: mark loads as non-null where applicable. 2016-03-29 13:34:37 +00:00
whitequark 330b232672 test: relax lit/embedding/syscall_flags. 
We currently have broken debug info. In either case, debug info
is irrelevant to this test.

Robert Jördens 049bd11bd6 scanwidget: handle min, max, suffix (closes #352) 2016-03-28 16:59:49 +02:00
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.

whitequark 418f0a5234 compiler: mark loads of kernel constant attributes as load invariant.
