Ok, I was dreading to do this, but finally got enough courage. Here's where we stand on ARM testing. I am running them one at a time to see which tests run all the way without failure, so that we can focus attention on a smaller set. A few more tests still remain to be run, and I will update with the full list next week.

Looks like there was a type in datessysinfo, I'd be interested to know if there are any failures in dates.

Probably some of these are the same memory error causing #8314.

It looks slightly better now but still get a failure in numbers, strings, unicode, bitarray, random, math, parallel, and readdlm.

The readdlm failure might be due to an old LLVM bug: http://llvm.org/bugs/show_bug.cgi?id=7048

The equality test seems broken, which is making the numbers test fail. This should be false:

Hmm, the first operand seems to be getting trucated in the lowering:
(with x() = typemax(Uint64) == 2.0^64)

julia> @code_typed x()

 :($(Expr(:lambda, Any[], Any[Any[],Any[],Any[]], :(begin  # none, line 1:

    end::Bool))))

Maybe missing some flag to flisp? (works as expected on win32)

can you try a bit pattern e.g. 0x123456789ABCDEF0. would be good to see if it is getting the high or low bits

Never having been one to leave well-enough alone, I switched the crouton version of Ubuntu to utopic on my Chromebook. Partly I wanted to see if it would be possible to use more of the system libraries from Ubuntu 14.10, such as llvm-3.5, to make installation faster.

I started with a compilation in the recommended way (i.e. my Make.user only includes ARM.inc) and it did compile. However, but the program dies on a segfault immediately after the splash screen.

alright, cool: so someone is definitely truncating that number. any idea who? for example, if you look at the jl_uncompress_ast(linfo, linfo->ast)?

ihnorton commented Nov 6, 2014

False start - I think the half-output is just a jl_static_show issue. jl_uncompress_ast shows the truncation, but code_typed calls that too and does not show truncation (while using higher--end display code instead of static_show)

I grab the LLVM Values then we see they are lowered correctly.

Here is something a little bit odd: putting this test inside a function on Win64 gives the wrong answer; doing the same on ARM gives the correct answer.

Windows 64:

julia> typemax(UInt64) == 2.0^64
false
julia> f() = typemax(UInt64) == 2.0^64
f (generic function with 1 method)
julia> f()
true
julia> @code_llvm f()
define i1 @"julia_f;1120"() {
top:
  ret i1 true, !dbg !3415
}
julia> @code_typed f()
1-element Array{Any,1}:
 :($(Expr(:lambda, Any[], Any[Any[],Any[],Any[]], :(begin  # none, line 1:
        return (top(eqfui64))((GetfieldNode(Base.Math,:box,Any))(Float64,(Getfie
ldNode(Base.Math,:powi_llvm,Any))(2.0,(GetfieldNode(Base.Math,:box,Any))(Int32,(
top(checked_trunc_sint))(Int32,64))::Int32))::Float64,0xffffffffffffffff)::Bool
    end::Bool))))

Arm v7 (master):

julia> typemax(UInt64) == 2.0^64
true
julia> f() = typemax(UInt64) == 2.0^64
f (generic function with 1 method)
julia> f()
false
julia> @code_llvm f()

define i1 @julia_f40625() {
top:
  ret i1 false, !dbg !8
}
julia> @code_typed f()
1-element Array{Any,1}:
 :($(Expr(:lambda, Any[], Any[Any[],Any[],Any[]], :(begin  # none, line 1:
        return (top(eqfui64))((GetfieldNode(Base.Math,:box,Any))(Float64,(GetfieldNode(Base.Math,:powi_llvm,Any))(2.0,64))::Float64,0xffffffffffffffff)::Bool
    end::Bool))))

"Win64 gives the wrong answer", maybe not helping much, just confirming (after fixing UInt32->Uint32, is it a typo or do both work in never versions?) also incorrect on Linux in my 64-bit 0.3.2 (non-ARM):

julia> f() = typemax(Uint64) == 2.0^64
f (generic function with 1 methods)

julia> f()
true

UintXX were renamed recently to UIntXX on 0.4-dev. Slightly annoying change that has caused a few conflicts when trying to backport things, but it does look better and I think there are deprecations in place.

I am now using OpenBLAS here and weirdly enough I get this, which does not happen if I multiply 100x100 matrices.

julia> rand(1000,1000)*rand(1000,1000)
ERROR: InexactError()

Also stuff like arrayops and reduce that used to pass before is no longer passing. I don't know if this is because of the switch to using openblas or some other commit in the last month.

@ViralBShah This sounds awfully like #9107.

I am filing individual issues for each failure.
