bind's glue function should tail-call its target #2

graydon · 2010-06-22T18:06:08Z

Currently the glue function for `bind' does a non-tail call to the target
function. It should do the same thing as a tail call.

Shifted to rustc issue

This has now basically been punted over to #217.

On Linux/Mac, I got a segmentation fault: (gdb) bt #0 0x00000000007519af in glue_take584 () rust-lang#1 0x00000000006d4bec in back::rpath::get_rpath_flags::_3899df2ca513c603 () rust-lang#2 0x00000000006c7655 in back::link::link_binary::_7afde00a9791031c () rust-lang#3 0x00000000007d3ff5 in driver::rustc::compile_input::thunk9212 () rust-lang#4 0x0000000000710f24 in driver::rustc::time::_3e691b2a4ba58aee () rust-lang#5 0x000000000071a79d in driver::rustc::compile_input::_7b4a41b87c18e034 () rust-lang#6 0x000000000072f0a9 in driver::rustc::main::_cd8b8c8185af3dee () rust-lang#7 0x000000000072f1ed in _rust_main () rust-lang#8 0x00007ffff7e6e146 in task_start_wrapper (a=<optimized out>) at ../src/rt/rust_task.cpp:176 The variable `output` or `out_filename` becomes (null) after the definition of `fn unlib`. Move the function defintion to the beginning seems prevent the crash on Linux.

Good morning, It's taken a long time, but I finally am almost done freeing libsyntax of `vecs_implicitly_copyable` in this pull request, but I'm running into some issues. I've confirmed that all but the last commit (which only disables `vecs_implicitly_copyable` pass the `check` tests. The last commit errors with this message, which makes no sense to me: ``` /Users/erickt/rust/rust/src/libcore/num/f32.rs:35:37: 35:43 error: expected `,` but found `=` /Users/erickt/rust/rust/src/libcore/num/f32.rs:35 pub pure fn $name($( $arg : $arg_ty ),*) -> $rv { ^~~~~~ ``` and this stack trace: ``` #1 0x00000001000b059b in sys::begin_unwind_::_a923ca4ae164c::_06 () #2 0x00000001000b0542 in sys::begin_unwind::anon::anon::expr_fn_13876 () #3 0x00000001000048a1 in sys::begin_unwind::_8ec273289fc0adc0::_06 () #4 0x00000001005df999 in diagnostic::__extensions__::meth_7941::span_fatal::_efdf2d14612d79ec::_06 () #5 0x0000000100682d48 in parse::parser::__extensions__::meth_16938::fatal::_8aa3239426747a3::_06 () #6 0x00000001006850b8 in parse::common::__extensions__::meth_17005::expect::_d3604ec6c7698d5f::_06 () #7 0x00000001006b59f1 in parse::common::__extensions__::parse_seq_to_before_end_17860::_48c79835f9eb1011::_06 () #8 0x00000001006a50f7 in parse::parser::__extensions__::meth_17606::parse_fn_decl::_14f3785fe78967d::_06 () #9 0x00000001006b6f59 in parse::parser::__extensions__::meth_17987::parse_item_fn::_8a6be529cf7b2ca5::_06 () #10 0x00000001006ac839 in parse::parser::__extensions__::meth_17761::parse_item_or_view_item::_bfead947d6dd7d25::_06 () #11 0x00000001006c8b8f in parse::parser::__extensions__::meth_18364::parse_item::_96b54e33f65abe76::_06 () #12 0x000000010076179f in ext::tt::macro_rules::add_new_extension::generic_extension::anon::anon::expr_fn_23365 () #13 0x000000010072e793 in ext::expand::expand_item_mac::_a4f486c4465cfb1b::_06 () #14 0x00000001007b5ad3 in __morestack () ``` There also a bunch of new warnings that I haven't cleaned up yet: https://gist.github.com/erickt/5048251. @nikomatsakis thought there might be some scary bug in the parser caused by moving a vector in the parser instead of copying it, which is why I'm filing this pull request before it's ready. Thanks for any help!

…wLii Change prefetch to avoid deadlock Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock. This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more. ```

Change prefetch to avoid deadlock Was abled to reproduce the deadlock in #118205 and created a coredump when it happen. When looking at the backtraces I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock. This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more. ```

Add the following two optional flags to `libtest` (rustc's built-in unit-test framework), in order to support postprocessing of the test results using a separate executable: * `--output_postprocess_executable [PATH]` * `--output_postprocess_args [ARGUMENT]` (can be repeated.) If you don't pass `--output_postprocess_executable [PATH]`, the behavior stays the same as before this commit. That is, the test results are sent to stdout. If you pass `--output_postprocess_executable [PATH]`, `libtest` will 1. Spawn a child process from the executable binary (aka *postprocessor*) at the given path. 2. Pass the arguments from the `--output_postprocess_args [ARGUMENT]` flags (if any) to the child process. If `--output_postprocess_args` was used multiple times, all listed arguments will be passed in the original order. 3. Propagate the environment variables to the child process. The *postprocessor* executable is expected to wait for the end of input (EOF) and then terminate. Usage example #1: Filter lines of the test results ```shell $ LD_LIBRARY_PATH=$(pwd) ./test-05daf44cb501aee6 --output_postprocess_executable=/usr/bin/grep --output_postprocess_args="test result" test result: ok. 59 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 0.31s ``` Usage example rust-lang#2: Save test results into a file ```shell $ LD_LIBRARY_PATH=$(pwd) ./test-05daf44cb501aee6 --output_postprocess_executable=/usr/bin/sh --output_postprocess_args=-c --output_postprocess_args="cat > /tmp/output.txt" ``` Usage example rust-lang#3: Save test results into a file while keeping the command line output ```shell $ LD_LIBRARY_PATH=$(pwd) ./test-05daf44cb501aee6 --output_postprocess_executable=/usr/bin/tee --output_postprocess_args="/tmp/output.txt" running 60 tests ... ``` Usage example rust-lang#4: Prepend every line of test results with the value of an environment variable (to demonstrate environment variable propagation) ```shell $ LOG_PREFIX=">>>" LD_LIBRARY_PATH=$(pwd) ./test-05daf44cb501aee6 --output_postprocess_executable=/usr/bin/sh --output_postprocess_args=-c --output_postprocess_args="sed s/^/\$LOG_PREFIX/" >>> >>>running 60 tests ... ``` Usage example rust-lang#5: Change format of JSON output (using https://jqlang.github.io/jq/) ```shell $ LD_LIBRARY_PATH=$(pwd) ./test-05daf44cb501aee6 -Zunstable-options --format=json --output_postprocess_executable=/usr/bin/jq ``` Usage example rust-lang#6: Print test execution time in machine-readable format ```shell $ LD_LIBRARY_PATH=$(pwd) ./test-05daf44cb501aee6 -Zunstable-options --format=json --output_postprocess_executable=/usr/bin/jq --output_postprocess_args=".exec_time | numbers" 0.234317996 ``` Rationale for adding this functionality: * Bazel (build system) doesn't provide a way to process output from a binary (in this case, Rust test binary's output) other using a wrapper binary. However, using a wrapper binary potentially breaks debugging, because Bazel would suggest to debug the wrapper binary rather than the Rust test itself. * See bazelbuild/rules_rust#1303. * Cargo is not used in Rust Bazel rules. * Although we could wait for rust-lang#96290 and then modify Rust Bazel rules to pass `--logfile` on the command line to provisionally unblock bazelbuild/rules_rust#1303, that solution still wouldn't allow advanced test results postprocessing such as changing JSON/XML schema and injecting extra JUnit properties. * Due to limitations of Rust libtest formatters, Rust developers often use a separate tool to postprocess the test results output (see comments to rust-lang#85563). * Examples of existing postprocessing tools: * https://crates.io/crates/cargo2junit * https://crates.io/crates/gitlab-report * https://crates.io/crates/cargo-suity * For these use cases, it might be helpful to use the new flags `--output_postprocess_executable`, `--output_postprocess_args` instead of piping the test results explicitly, e.g. to more reliably separate test results from other output. Rationale for implementation details: * Use platform-dependent scripts (.sh, .cmd) because it doesn't seem to be possible to enable unstable feature `bindeps` (https://rust-lang.github.io/rfcs/3028-cargo-binary-dependencies.html) in "x.py" by default. * Here's a preexisting test that also uses per-platform specialization: `library/std/src/process/tests.rs`.

…-codegen-tests, r=erikdesjardins,workingjubilee Repair several `riscv64gc-unknown-linux-gnu` codegen tests Together with joshua.zivkovic@codethink.co.uk, we've been starting to explore improving the state of the `riscv64gc-unknown-linux-gnu` target. Additionally, I'm looking to add support for this platform in [Ferrocene](https://github.com/ferrocene/ferrocene) ([Related PR](ferrocene/ferrocene#618)). While running the test suite, we noted several tests were failing. It appears that several of the riscv64gc-unknown-linux-gnu codegen tests have not been updated in some time and seem to have experienced a small amount of bitrot. After speaking with `@workingjubilee` (as I have little expertise in LLVM codegen) I believe these changes to be correct. ### `tests/codegen/riscv-abi/call-llvm-intrinsics.rs` I believe this change does not alter what the test is testing and is harmless. ### `tests/codegen/riscv-abi/riscv64-lp64d-abi.rs` The changes largely mirrors those from loongarch64: https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L15 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L153-L155 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L259-L261 https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L263-L267 ### `tests/codegen/riscv-abi/riscv64-lp64f-lp64d-abi.rs` The changes largely mirror that from loongarch64 or llvm: https://github.com/rust-lang/rust/blob/550d1b4fb6de23990f4108815c3b1a9d1659e5c4/tests/codegen/loongarch-abi/loongarch64-lp64d-abi.rs#L13-L26 https://github.com/rust-lang/llvm-project/blob/5399a24c66cb6164cf32280e7d300488c90d5765/clang/test/CodeGen/RISCV/riscv64-abi.c#L612-L617 ### `tests/ui/debuginfo/debuginfo-emit-llvm-ir-and-split-debuginfo.rs` The test is ignored since `-Csplit-debuginfo=unpacked` is not supported on this platform. Context can be found in rust-lang#120518. ## Reproducing the failures Using a `config.toml` with the following: ```toml # ... target = [ # ...
