Subject: [bug#35388] [PATCH] gnu: julia: Update to 1.1.0

From: Nicolò Balzarotti <[email-masked]>
Date: Tue, 23 Apr 2019 10:32:04 +0000

Hi,
I'm sorry but the previous patch wasn't applying, and it was missing the
llvm-patches.
Hope this time it works.
Julia in this package compiles, runs, install packages & so on. It takes a
bit to compile, so I have yet to check it's reproducible.

Thanks,
Nicolò

> +    [JumpThreading] Don't restrict cast-traversal to i1
> +
> +    Summary:
> +    In D17663, JumpThreading learned to look trough simple cast
> instructions,
> +    but only if the source of those cast instructions was a phi/cmp i1
> +    (in an effort to limit compile time effects). I think this condition
> +    is too restrictive. For switches with limited value range, InstCombine
> +    will readily introduce an extra `trunc` instruction to a smaller
> +    integer type (e.g. from i8 to i2), leaving us in the somewhat perverse
> +    situation that jump-threading would work before running instcombine,
> +    but not after. Since instcombine produces this pattern, I think we
> +    need to consider it canonical and support it in JumpThreading.
> +    In general, for limiting recursion, I think the existing restriction
> +    to phi and cmp nodes should be sufficient to avoid looking through
> +    unprofitable chains of instructions.

> +    [SCEV] Don't expand Wrap predicate using inttoptr in ni addrspaces
> +
> +    Summary:
> +    In non-integral address spaces, we're not allowed to introduce
> inttoptr/ptrtoint
> +    intrinsics. Instead, we need to expand any pointer arithmetic as geps
> on the
> +    base pointer. Luckily this is a common task for SCEV, so all we have
> to do here
> +    is hook up the corresponding helper function and add test case.

> +    optimizer cannot deduce afterwards in a generic way (though we
> +    have frontend specific passes in our pipline that do propagate
> +    these). In any case, I'm sure nobody is using it this way at
> +    the moment, since it would have introduced inttoptrs, which

> +    RFC: [SCEV] Add explicit representations of umin/smin
> +
> +    Summary:
> +    Currently we express umin as `~umax(~x, ~y)`. However, this becomes
> +    a problem for operands in non-integral pointer spaces, because `~x`
> +    is not something we can compute for `x` non-integral. However, since
> +    comparisons are generally still allowed, we are actually able to
> +    express `umin(x, y)` directly as long as we don't try to express is
> +    as a umax. Support this by adding an explicit umin/smin representation
> +    to SCEV. We do this by factoring the existing getUMax/getSMax
> functions
> +    into a new function that does all four. The previous two functions
> +    were largely identical, except that the SMax variant used
> `isKnownPredicate`
> +    while the UMax variant used `isKnownViaNonRecursiveReasoning`.
> +
> +    Trying to make the UMax variant also use `isKnownPredicate` yields to
> +    an infinite recursion, while trying to make the `SMax` variant use
> +    `isKnownViaNonRecursiveReasoning` causes
> +    `Transforms/IndVarSimplify/backedge-on-min-max.ll` to fail.
> +
> +    I would appreciate any insight into which predicate is correct here.

> +    [LSR] Don't force bases of foldable formulae to the final type.
> +
> +    Summary:
> +    Before emitting code for scaled registers, we prevent
> +    SCEVExpander from hoisting any scaled addressing mode
> +    by emitting all the bases first. However, these bases
> +    are being forced to the final type, resulting in some
> +    odd code.
> +
> +    For example, if the type of the base is an integer and
> +    the final type is a pointer, we will emit an inttoptr
> +    for the base, a ptrtoint for the scale, and then a
> +    'reverse' GEP where the GEP pointer is actually the base
> +    integer and the index is the pointer. It's more intuitive
> +    to use the pointer as a pointer and the integer as index.
