All other functions are "device" functions. --- src/bootstrap/native.rs | 2 +- src/etc/platform-intrinsics/nvptx/cuda.json | 13 +++ src/etc/platform-intrinsics/nvptx/info.json | 7 ++ src/etc/platform-intrinsics/nvptx/sreg.json | 90 ++++++++++++++++++++ src/librustc_llvm/build.rs | 2 +- src/librustc_llvm/ffi.rs | 1 + src/librustc_llvm/lib.rs | 5 ++ src/librustc_platform_intrinsics/lib.rs | 3 + src/librustc_platform_intrinsics/nvptx.rs | 92 +++++++++++++++++++++ src/librustc_trans/abi.rs | 5 ++ src/librustc_trans/cabi_nvptx.rs | 53 ++++++++++++ src/librustc_trans/cabi_nvptx64.rs | 53 ++++++++++++ src/librustc_trans/lib.rs | 2 + src/libsyntax/abi.rs | 2 + src/libsyntax/feature_gate.rs | 17 +++- 15 files changed, 344 insertions(+), 3 deletions(-) create mode 100644 src/etc/platform-intrinsics/nvptx/cuda.json create mode 100644 src/etc/platform-intrinsics/nvptx/info.json create mode 100644 src/etc/platform-intrinsics/nvptx/sreg.json create mode 100644 src/librustc_platform_intrinsics/nvptx.rs create mode 100644 src/librustc_trans/cabi_nvptx.rs create mode 100644 src/librustc_trans/cabi_nvptx64.rs diff --git a/src/bootstrap/native.rs b/src/bootstrap/native.rs index 09dbd9f8220b0..80f27a5ab673f 100644 --- a/src/bootstrap/native.rs +++ b/src/bootstrap/native.rs @@ -81,7 +81,7 @@ pub fn llvm(build: &Build, target: &str) { .profile(profile) .define("LLVM_ENABLE_ASSERTIONS", assertions) .define("LLVM_TARGETS_TO_BUILD", - "X86;ARM;AArch64;Mips;PowerPC;SystemZ;JSBackend;MSP430;Sparc") + "X86;ARM;AArch64;Mips;PowerPC;SystemZ;JSBackend;MSP430;Sparc;NVPTX") .define("LLVM_INCLUDE_EXAMPLES", "OFF") .define("LLVM_INCLUDE_TESTS", "OFF") .define("LLVM_INCLUDE_DOCS", "OFF") diff --git a/src/etc/platform-intrinsics/nvptx/cuda.json b/src/etc/platform-intrinsics/nvptx/cuda.json new file mode 100644 index 0000000000000..1beaaeb5d8718 --- /dev/null +++ b/src/etc/platform-intrinsics/nvptx/cuda.json @@ -0,0 +1,13 @@ +{ + "intrinsic_prefix": "_", + "llvm_prefix": "llvm.cuda.", + "intrinsics": [ + { + "intrinsic": "syncthreads", + "width": ["0"], + "llvm": "syncthreads", + "ret": "V", + "args": [] + } + ] +} diff --git a/src/etc/platform-intrinsics/nvptx/info.json b/src/etc/platform-intrinsics/nvptx/info.json new file mode 100644 index 0000000000000..80332c54e0414 --- /dev/null +++ b/src/etc/platform-intrinsics/nvptx/info.json @@ -0,0 +1,7 @@ +{ + "platform": "nvptx", + "number_info": { + "signed": {} + }, + "width_info": {} +} diff --git a/src/etc/platform-intrinsics/nvptx/sreg.json b/src/etc/platform-intrinsics/nvptx/sreg.json new file mode 100644 index 0000000000000..33d97f2694699 --- /dev/null +++ b/src/etc/platform-intrinsics/nvptx/sreg.json @@ -0,0 +1,90 @@ +{ + "intrinsic_prefix": "_", + "llvm_prefix": "llvm.nvvm.read.ptx.sreg.", + "intrinsics": [ + { + "intrinsic": "block_dim_x", + "width": ["0"], + "llvm": "ntid.x", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "block_dim_y", + "width": ["0"], + "llvm": "ntid.y", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "block_dim_z", + "width": ["0"], + "llvm": "ntid.z", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "block_idx_x", + "width": ["0"], + "llvm": "ctaid.x", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "block_idx_y", + "width": ["0"], + "llvm": "ctaid.y", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "block_idx_z", + "width": ["0"], + "llvm": "ctaid.z", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "grid_dim_x", + "width": ["0"], + "llvm": "nctaid.x", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "grid_dim_y", + "width": ["0"], + "llvm": "nctaid.y", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "grid_dim_z", + "width": ["0"], + "llvm": "nctaid.z", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "thread_idx_x", + "width": ["0"], + "llvm": "tid.x", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "thread_idx_y", + "width": ["0"], + "llvm": "tid.y", + "ret": "S32", + "args": [] + }, + { + "intrinsic": "thread_idx_z", + "width": ["0"], + "llvm": "tid.z", + "ret": "S32", + "args": [] + } + ] +} diff --git a/src/librustc_llvm/build.rs b/src/librustc_llvm/build.rs index e681a81cf0c3f..2ee4cc4943561 100644 --- a/src/librustc_llvm/build.rs +++ b/src/librustc_llvm/build.rs @@ -96,7 +96,7 @@ fn main() { let optional_components = ["x86", "arm", "aarch64", "mips", "powerpc", "pnacl", "systemz", "jsbackend", "msp430", - "sparc"]; + "sparc", "nvptx"]; // FIXME: surely we don't need all these components, right?

Rust is a bootstrapped language which means that a previous version of the compiler is used to build the next version of the compiler. Over time, however, we change many parts of compiler artifacts such as the metadata format, symbol names, etc. These changes make artifacts from one compiler incompatible from another compiler. Consequently if a compiler wants to be able to use some artifacts then it itself must have compiled the artifacts. Historically the rustc build system has achieved this by compiling the compiler three times: * An older compiler (stage0) is downloaded to kick off the chain. * This compiler now compiles a new compiler (stage1) * The stage1 compiler then compiles another compiler (stage2) * Finally, the stage2 compiler needs libraries to link against, so it compiles all the libraries again. This entire process amounts in compiling the compiler three times. Additionally, this process always guarantees that the Rust source tree can compile itself because the stage2 compiler (created by a freshly created compiler) would successfully compile itself again. This property, ensuring Rust can compile itself, is quite important! In general, though, this third compilation is not required for general purpose development on the compiler. The third compiler (stage2) can reuse the libraries that were created during the second compile. In other words, the second compilation can produce both a compiler and the libraries that compiler will use. These artifacts *must* be compatible due to the way plugins work today anyway, and they were created by the same source code so they *should* be compatible as well. So given all that, this commit switches the default build process to only compile the compiler three times, avoiding this third compilation by copying artifacts from the previous one. Along the way a new entry in the Travis matrix was also added to ensure that our full bootstrap can succeed. This entry does not run tests, though, as it should not be necessary. To restore the old behavior of a full bootstrap (three compiles) you can either pass: ./configure --enable-full-bootstrap or if you're using config.toml: [build] full-bootstrap = true Overall this will hopefully be an easy 33% win in build times of the compiler. If we do 33% less work we should be 33% faster! This in turn should affect cycle times and such on Travis and AppVeyor positively as well as making it easier to work on the compiler itself. --- .travis.yml | 1 + configure | 1 + src/bootstrap/check.rs | 18 +- src/bootstrap/compile.rs | 92 +++++---- src/bootstrap/config.rs | 4 + src/bootstrap/config.toml.example | 7 + src/bootstrap/doc.rs | 15 ++ src/bootstrap/lib.rs | 28 ++- src/bootstrap/step.rs | 181 ++++++++++++------ .../x86_64-gnu-full-bootstrap/Dockerfile | 28 +++ 10 files changed, 262 insertions(+), 113 deletions(-) create mode 100644 src/ci/docker/x86_64-gnu-full-bootstrap/Dockerfile diff --git a/.travis.yml b/.travis.yml index ea8c94af80b72..dd5fe7cd04324 100644 --- a/.travis.yml +++ b/.travis.yml @@ -17,6 +17,7 @@ matrix: - env: IMAGE=i686-gnu-nopt - env: IMAGE=x86_64-freebsd - env: IMAGE=x86_64-gnu + - env: IMAGE=x86_64-gnu-full-bootstrap - env: IMAGE=x86_64-gnu-cargotest - env: IMAGE=x86_64-gnu-debug - env: IMAGE=x86_64-gnu-nopt diff --git a/configure b/configure index 4f1e8f656ae22..5094e5a764bdf 100755 --- a/configure +++ b/configure @@ -693,6 +693,7 @@ opt_nosave manage-submodules 1 "let the build manage the git submodules" opt_nosave clang 0 "prefer clang to gcc for building the runtime" opt_nosave jemalloc 1 "build liballoc with jemalloc" opt elf-tls 1 "elf thread local storage on platforms where supported" +opt full-bootstrap 0 "build three compilers instead of two" valopt_nosave prefix "/usr/local" "set installation prefix" valopt_nosave local-rust-root "/usr/local" "set prefix for local rust binary" diff --git a/src/bootstrap/check.rs b/src/bootstrap/check.rs index e7b0afeb8ce63..ec0243908edab 100644 --- a/src/bootstrap/check.rs +++ b/src/bootstrap/check.rs @@ -341,12 +341,22 @@ pub fn krate(build: &Build, println!("{} {} stage{} ({} -> {})", test_kind, name, compiler.stage, compiler.host, target); + // If we're not doing a full bootstrap but we're testing a stage2 version of + // libstd, then what we're actually testing is the libstd produced in + // stage1.
