2020-03-30Tone down the legacy toolchain removal note.Dan Albert
Removing *all* of these hinges on us being able to remove binutils because a final part of the cleanup will be removing the target-specific bin directories within the LLVM toolchain, which can affect driver behavior. Since we don't know if we'll be able to get that done for next year's LTS, don't be so explicit about the timeline. We can be more specific when we know more.

2020-03-24Default to lld again.Dan Albert
Rather than trying to replace `ld` in each location, this instead relies on Clang defaulting to `ld.lld`, which it invokes from the Clang bin directory. Test: treehugger Bug: None Change-Id: I32b0655c0d89522848f044f1067b53f9214c5444
2020-03-18Revert "Switch to LLD as the default linker."Dan Albert
This reverts commit 393761d2e07461366ea456cea7f67fade95e3b4b. This broke Darwin. It seems that LLD assumes the target based on the name of the executable, so it can't be reliably used from the target-specific directory as I tried to do here. Trying to use this with Darwin results in the following: ``` ld: warning: ignoring unknown argument: -z ld: warning: ignoring unknown argument: --warn-shared-textrel ld: warning: ignoring unknown argument: -z ld: warning: ignoring unknown argument: -z ld: warning: ignoring unknown argument: --hash-style=both ld: warning: ignoring unknown argument: --enable-new-dtags ld: warning: ignoring unknown argument: --eh-frame-hdr ld: warning: ignoring unknown argument: -m ld: warning: ignoring unknown argument: -dynamic-linker ld: warning: ignoring unknown argument: -plugin ld: warning: ignoring unknown argument: -plugin-opt=mcpu=x86-64 ld: warning: ignoring unknown argument: --gc-sections ld: warning: ignoring unknown argument: -rpath-link=/Volumes/Android/danalbert/ndk/out/darwin/android-ndk-r22-canary/toolchains/llvm/prebuilt/darwin-x86_64/sysroot/usr/lib/x86_64-linux-android/21 ld: warning: ignoring unknown argument: -rpath-link=./obj/local/x86_64 ld: warning: ignoring unknown argument: --exclude-libs ld: warning: ignoring unknown argument: --exclude-libs ld: warning: ignoring unknown argument: --exclude-libs ld: warning: ignoring unknown argument: --build-id ld: warning: ignoring unknown argument: --no-undefined ld: warning: ignoring unknown argument: --fatal-warnings ld: error: -arch not specified and could not be inferred clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` It's trivially fixed with `-fuse-ld=lld`, which causes Clang to pick LLD from a different directory and passes the target explicitly. We could do that in ndk-build and in the CMake toolchain to change the default for those systems, but we really need to upstream a patch to change the default in the Clang driver to affect other build systems.

2019-11-08Only use explicit --build-id=tree for lld.Dan Albert
Using sha1 instead of tree turned out to have a larger build impact than the benchmarking suggested (10% regression in dolphin build time). For ndk-build, scan all the linker flags for -fuse-ld and check APP_LD to determine if lld is being used, and if it is then fallback to tree. Otherwise, use the linker default. For CMake we don't know the user's chosen ldflags, so the best we can do is work off of ANDROID_LD. If the user doesn't use ANDROID_LD and instead uses -fuse-ld=lld explicitly, they won't be able to debug. Test: inspected verbose build output for the following configurations: * No flags * APP_LD=lld * APP_LD=gold * APP_LD=lld APP_LDFLAGS=-fuse-ld=gold * APP_LD=gold APP_LDFLAGS=-fuse-ld=lld * For the first three variants, checked CMake with ANDROID_LD.

2019-10-04Merge "Fix unwinder visibility for most ABIs."Treehugger Robot
2019-10-04Fix unwinder visibility for most ABIs.Dan Albert
When we switched to using a linker script for libgcc in r19 we broke `-Wl,--exclude-libs,libgcc.a`, because `--exclude-libs` has no effect on the contents of linker scripts. As such, libgcc was not being hidden as expected. The good news is that on the one platform this causes the most trouble (Arm32, since it uses the LLVM unwinder for exception handling rather than libgcc) this didn't cause any issues. Since libunwind was linked first (and the `--exclude-libs` worked there, since the actual library was named), the libgcc unwind symbols did not end up in the output at all. So while this has not caused any issues, it is still a good idea for us to link libgcc hidden to guard against any future unwind ABI breaks. Test: Added a test that checks ndk-build output with readelf Bug: https://github.com/android/ndk/issues/1092 Change-Id: I5c8203afd29f0b7b272a51aadfc1a5ca6cbd33e4

2019-09-25Allow externally specified import paths.Dan Albert
Gradle needs to be able to specify a dependency import path for Prefab modules. Add NDK_GRADLE_INJECTED_IMPORT_PATH to support this. This could instead be a more generic NDK_ADDITIONAL_IMPORT_PATHS, but that's probably of limited use since Gradle will clobber the user's flags with its own.

2019-09-17Remove useless cxx-stl/system module.Dan Albert
This used to be used to export the system's basic C++ headers to projects, but that's now handled directly by the toolchain. Anyone that was explicitly linking this module will get the usual "you're linking something that doesn't exist, are you sure you meant to?" message. Anyone explicitly importing this directory will receive a less clear error message of "could not find cxx-stl/system". Both of these error cases are extremely unlikely since this has never been something user's have needed to do.
