Looks like a bug fix? Could this go directly to master?

mostly this was caused because I accidentally was passing a copy of the array in the pointer, rather than the array itself (during work on this PR). it shouldn't strictly be necessary on master (since pcre should set this variable)

Really nice change. The amount of code deletion speaks for itself :) |

This is a great hack. It looks correct to me; hope I'm right about that :)

yeah, i'll definately have to do more testing on this. i probably will hold off on merging until I get a few more of the ccall-related PR's ready. the runtime code branch is identical to the compile-time code branch directly above it, however.

oops, it /was/ slightly broken.

indeed. i'm also working on deprecating |

it's possibly there to help inference correctly count usages correctly? i'm not really sure |

Does the travis failure make any sense to you? If neither of us can figure out why the extra root is there we should try removing it. |

yeah, that should be fixed in my followup fix (two bugs: i was looking for |

fix bug in worker-to-worker connection setup. closes #9951

Not exported. Fixes #9957.
Fix `show_method_candidates` so it do not fail for methods with zero args.
Inbuilt managers throw on unused arguments. Closes #9958

Correct rounding mode after calling fma
ccall(:a, B, (C,), d) is now lowered as:
d#1 = cconvert_gcroot(C, d)
Expr(:call, :ccall, :a, B, (C,), cconvert(C, d#1), d#1)
This allows implementation of the special-case ccall lowering logic in Julia
and still create a gcroot for it as needed
the Ref{T} type is the new supertype of Ptr{T}. the ccall emission
turns a Ref{T} into a Ptr{T}, as if the &addressOf operator had been
applied. the specific rules for this will be moved from the current
gist to the documentation at a later point.

It also means that the fall-back cconvert method is now a no-op, with the main
work being done by convert. But it also means we get a GC root for both
the result of cconvert and convert (as needed).
ps: this was the motivation for #9729
