The jemalloc build is controlled by a feature of the std crate, and if that feature changes between targets, it invalidates the fingerprint of std's build script (this is a cargo bug); so we must ensure that the feature set used by std is the same across all targets, which means we have to build the alloc_jemalloc crate for targets like emscripten, even if we don't use it. --- src/bootstrap/sanity.rs | 17 ++- src/liballoc_jemalloc/build.rs | 18 +++ src/liballoc_jemalloc/lib.rs | 262 ++++++++++++++++++++++++----------------- 3 files changed, 180 insertions(+), 117 deletions(-) (limited to 'src/liballoc_jemalloc') diff --git a/src/bootstrap/sanity.rs b/src/bootstrap/sanity.rs index 962d0666f69..9429af56525 100644 --- a/src/bootstrap/sanity.rs +++ b/src/bootstrap/sanity.rs @@ -104,6 +104,14 @@ pub fn check(build: &mut Build) { need_cmd(build.cxx(host).as_ref()); } + // The msvc hosts don't use jemalloc, turn it off globally to + // avoid packaging the dummy liballoc_jemalloc on that platform. + for host in build.config.host.iter() { + if host.contains("msvc") { + build.config.use_jemalloc = false; + } + } + // Externally configured LLVM requires FileCheck to exist let filecheck = build.llvm_filecheck(&build.config.build); if !filecheck.starts_with(&build.out) && !filecheck.exists() && build.config.codegen_tests { @@ -111,15 +119,6 @@ pub fn check(build: &mut Build) { } for target in build.config.target.iter() { - // Either can't build or don't want to run jemalloc on these targets - if target.contains("rumprun") || - target.contains("bitrig") || - target.contains("openbsd") || - target.contains("msvc") || - target.contains("emscripten") { - build.config.use_jemalloc = false; - } - // Can't compile for iOS unless we're on OSX if target.contains("apple-ios") && !build.config.build.contains("apple-darwin") { diff --git a/src/liballoc_jemalloc/build.rs b/src/liballoc_jemalloc/build.rs index 8b31c5a5577..028d742cc83 100644 --- a/src/liballoc_jemalloc/build.rs +++ b/src/liballoc_jemalloc/build.rs @@ -27,6 +27,24 @@ fn main() { let build_dir = PathBuf::from(env::var_os("OUT_DIR").unwrap()); let src_dir = env::current_dir().unwrap(); + // FIXME: This is a hack to support building targets that don't + // support jemalloc alongside hosts that do.
