Package: llvm-3.9-dev Version: 1:3.9-4 Severity: important Tags: patch Dear Maintainer,
Please apply the patch here: https://reviews.llvm.org/rL279980 Otherwise issue-36023.rs in rustc 1.12.1 will compile but segfault when run: https://github.com/rust-lang/rust/issues/36023 https://llvm.org/bugs/show_bug.cgi?id=29163 To clarify my earlier comments on IRC, the other patch you already applied is correct and should be kept: https://reviews.llvm.org/rL281650 Otherwise issue-36474.rs in rustc 1.12.1 will infinite-loop when trying to compile it: https://github.com/rust-lang/rust/issues/36474 https://llvm.org/bugs/show_bug.cgi?id=30402 In summary, both patches are needed. X ---- In fact, here is the full list of differences between rustc's LLVM (stable branch) and ours: rust.git$ git show --decorate=full commit d4f39402a0c2c2b94ec0375cd7f7f6d7918113cd (HEAD, tag: refs/tags/1.12.1, refs/remotes/upstream/stable) Merge: 3191fba 2d49342 Author: Brian Anderson <ander...@gmail.com> Date: Wed Oct 19 11:22:49 2016 -0700 Merge pull request #37173 from brson/stable-next [stable] Backports for 1.12.1 rust.git$ cd src/llvm/ rust.git$ git show commit ac1c94226e9fa17005ce7e2dd52dd6d1875f3137 Merge: abbf675 9b74379 Author: Alex Crichton <a...@alexcrichton.com> Date: Sat Oct 8 11:02:12 2016 -0700 Merge pull request #54 from arielb1/cleanup-is-not-a-jump Backport "[SimplifyCFG] Correctly test for unconditional branches in GetCaseResults" rust.git$ git format-patch 4105790 # 4105790 and earlier are already applied to our LLVM 0001-Add-some-Rust-allocation-functions-to-TargetLibraryI.patch 0002-Add-support-for-i1-compare-operations-to-X86-FastISe.patch 0003-Disable-the-PassInfo-cache-assertions-to-make-the-ca.patch 0004-Fix-cross-compiling-to-FreeBSD.patch 0005-Don-t-compile-usage-of-std-thread.patch 0006-Add-accessors-for-MCSubtargetInfo-CPU-and-Feature-ta.patch 0007-InstCombine-Infer-inbounds-on-geps-of-allocas.patch 0008-InstSimplify-Try-hard-to-simplify-pointer-comparison.patch 0009-InstSimplify-Fold-gep-gep-V-C-sub-0-V-to-C.patch 0010-InstSimplify-Fold-gep-gep-V-C-xor-V-1-to-C-1.patch 0011-SimplifyCFG-Hoisting-invalidates-metadata.patch 0012-Run-GVN-again-after-InstCombine.patch 0013-Backport-rL281650.patch 0014-Import-of-fastcomp-commit-4105790f1549808c1f1daa5250.patch 0015-SimplifyCFG-Correctly-test-for-unconditional-branche.patch 0016-Propagate-DBG_VALUE-entries-when-there-are-unvisited.patch 0017-Teach-LiveDebugValues-about-lexical-scopes.patch In 1:3.9-4 you applied 0013, and this bug report is me asking you to apply 0011. However if these two don't make our rustc work, then the heavy-handed approach would be to apply all of the above patches. I've tested that these apply cleanly to our LLVM 1:3.9-4, but not yet built the thing. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'stable'), (300, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.7.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
