-
-On musl libc the fopen64 and fopen are the same thing, but for
-compatibility they have a `#define fopen64 fopen`. Same applies for
-fseek64, fstat64, fstatvfs64, ftello64, lstat64, stat64 and tmpfile64.

-Subject: [PATCH] Fix ScalarEvolutionExpander step scaling bug
-
-The expandAddRecExprLiterally function incorrectly transforms
-`[Start + Step * X]` into `Step * [Start + X]` instead of the correct
-transform of `[Step * X] + Start`.
-
-This caused https://github.com/JuliaLang/julia/issues/14704#issuecomment-174126219
-due to what appeared to be sufficiently complicated loop interactions.
-
-Patch by Jameson Nash (jameson@juliacomputing.com).

-Subject: [PATCH] Optimize store of "bitcast" from vector to aggregate.
-
-This patch is what was the "instcombine" portion of D14185, with an additional
-test added (see julia_pseudovec in test/Transforms/InstCombine/insert-val-extract-elem.ll).
-The patch causes instcombine to replace sequences of extractelement-insertvalue-store
-that act essentially like a bitcast followed by a store.
-
-Differential review: http://reviews.llvm.org/D14260

-
-Alpine maintainer notes:
-  - Updated for llvm 3.8.1.
-  - This patch replaces llvm-D14260.patch from Julia.

-Subject: [PATCH] [Cloning] Clone every Function's Debug Info
-
-Summary:
-Export the CloneDebugInfoMetadata utility, which clones all debug info
-associated with a function into the first module. Also use this function
-in CloneModule on each function we clone (the CloneFunction entrypoint
-already does this).
-
-Without this, cloning a module will lead to DI quality regressions,
-especially since r252219 reversed the Function <-> DISubprogram edge
-(before we could get lucky and have this edge preserved if the
-DISubprogram itself was, e.g. due to location metadata).
-
-This was verified to fix missing debug information in julia and
-a unittest to verify the new behavior is included.
-
-Patch by Yichao Yu! Thanks!

-Subject: [PATCH] Cloning: Reduce complexity of debug info cloning and fix
- correctness issue.
-
-Commit r260791 contained an error in that it would introduce a cross-module
-reference in the old module. It also introduced O(N^2) complexity in the
-module cloner by requiring the entire module to be visited for each function.
-Fix both of these problems by avoiding use of the CloneDebugInfoMetadata
-function (which is only designed to do intra-module cloning) and cloning
-function-attached metadata in the same way that we clone all other metadata.
