This is a simple way to workaround the debugging issues caused by the rustc
wrapper used in the bootstrap process. Namely, it uses some obscure environment
variables and you can’t just copy the failed command and run it in the shell or
debugger to examine the failure more closely.
With `--on-fail` its possible to run an arbitrary command within exactly the
same environment under which rustc failed. Theres’s multiple ways to use this
new flag:
$ python x.py build --stage=1 --on-fail=env
would print a list of environment variables and the failed command, so a
few copy-pastes and you now can run the same rust in your shell outside the
bootstrap system.
$ python x.py build --stage=1 --on-fail=bash
Is a more useful variation of the command above in that it launches a whole
shell with environment already in place! All that’s left to do is copy-paste
the command just above the shell prompt!
Fixes rust-lang#38686
Fixes rust-lang#38221
* Update bootstrap to recognize the cputype 'sparcv9' (used on Solaris) * Change to never use -fomit-frame-pointer on Solaris or for sparc * Adds rust target sparcv9-sun-solaris Fixes rust-lang#39901
The mx_handle_wait_* syscalls in Magenta were renamed to mx_object_wait. The syscall is used in the Magenta/Fuchsia implementation of std::process, to wait on child processes. In addition, this patch enables the use of the system provided libbacktrace library on Fuchsia targets. Symbolization is not yet working, but at least it allows printing hex addresses in a backtrace and makes building succeed when the backtrace feature is not disabled.
This generated an ugly error with fakeroot before.
Give LLVM much more information about vtable pointers. Without the extra information, LLVM has to be rather pessimistic about vtables, preventing a number of obvious optimisations. * Makes the vtable pointer argument noalias and readonly. * Marks loads of the vtable pointer as nonnull. * Marks load from the vtable with `!invariant.load` metadata. Fixes rust-lang#39992
The mitigations for rust-lang#34978 involve passing `-Wa,-mrelax-relocations=no` to all C code we compile, and we just forgot to pass it when compiling musl itself. Closes rust-lang#39979
This doesn't belong in rustbuild itself, and now that we have only rustbuild we can move this out of the build system.
Add the `?Sized` bound as we don't require the type to be sized. Closes rust-lang#40011
The readdir_r function is deprecated on newer Posix systems because of various problems, and not implemented at all for Fuchsia. There are already implementations using both, and this patch switches Fuchsia over to the readdir-based one. Fixes rust-lang#40021 for Fuchsia, but that issue also contains discussion of what should happen for other Posix systems.
For use by RLS.
In addition to defining and handling the new option, we also add a method on librustc::Session for determining the necessity of overflow checks. This method provides a single point to sort out the three (!) different ways for turning on overflow checks: -C debug-assertions, -C overflow-checks, and -Z force-overflow-checks. Fixes rust-lang#33134.
Update the implementation of name_bytes to use the owned string (which is thread safe). Also bump the src/liblibc submodule now that's merged.
…, r=nrc Stabilize static_recursion Fix rust-lang#29719.
Added test for inclusive_range_syntax in compile-fail test suite Fixes rust-lang#39059 r? @est31 Forgot to leave a comment on the issue, hopefully nobody else is working on this one!
Ignore ASM tests on powerpc Part of rust-lang#39015
…hton add `-C overflow-checks` option In addition to defining and handling the new option, we also add a method on librustc::Session for determining the necessity of overflow checks. This method provides a single point to sort out the three (!) different ways for turning on overflow checks: -C debug-assertions, -C overflow-checks, and -Z force-overflow-checks. I was seeing a [run-pass/issue-28950.rs](https://github.com/rust-lang/rust/blob/b1363a73ede57ae595f3a1be2bb75d308ba4f7f6/src/test/run-pass/issue-28950.rs) failure on my machine with these patches, but I was also seeing the failure without the changes to the core compiler. We'll see what travis says. Fixes rust-lang#33134. r? @alexcrichton
…woerister detect "bootstrap outputs" when serializing the dep-graph Fixes rust-lang#39828. r? @michaelwoerister
trans: don't ICE when trying to create ADT trans-items ADTs are translated in-place from rustc_trans::callee, so no trans-items are needed. This fix will be superseded by the shimmir branch, but I prefer not to backport that to beta. Fixes rust-lang#39823. Beta-nominating because regression. r? @michaelwoerister
Add Gankro's table to nomicon/src/phantom-data.md Original: rust-lang#30069 (comment) Testing confirms that: - `PhantomData<fn() -> T>` does not actually enable drop checking. - `PhantomData<fn(T) -> T>` is neither variant nor contravariant.
Move COMPILER_TESTS.md out of the root directory See rust-lang#39896. r? @brson
