2025-09-26	re-order normalizations in run-make linker-warning test	Fabian Grünbichler	-1/+1
	otherwise a buildroot containing `libpanic_abort` would be mangled before being replaced by the build root placeholder value.. e.g., running `./x.py test --verbose tests/run-make/linker-warning` with rustc checked out in ~/ext/rustc-libpanic_abort will result in (output slightly shortened): ``` running 1 tests test [run-make] tests/run-make/linker-warning ...

2025-09-25	Remove an erroneous normalization step in `tests/run-make/linker-warning`	León Orell Valerian Liehr	-1/+0

2025-08-17	Fix up library crate order in linker test	Josh Triplett	-1/+1

2025-07-25	canonicalize build root in `tests/run-make/linker-warning`	Waffle Lapkin	-1/+3

2025-07-06	Update run-make test	ia0	-4/+25

2025-06-24	Fix normalization in linker-warning	bjorn3	-1/+2
	Ensure rustc_codegen_cranelift doesn't get normalized to rustc. And handle -Cpanic=abort.
2025-06-19	Adjust some run-make tests on cross-compile	Jieyou Xu	-1/+2

2025-06-12	ignore `run-make` tests that need `std` on `no_std` targets	Folkert de Vries	-0/+1
	In particular, anything that includes `none` in the target tripple, and `nvptx64-nvidia-cuda`
2025-06-08	Use the in-tree `compiler-builtins`	Trevor Gross	-1/+1
	Many of `std`'s dependency have a dependency on the crates.io `compiler-builtins` when used with the feature `rustc-std-workspace-core`. Use a Cargo patch to select the in-tree version instead. `compiler-builtins` is also added as a dependency of `rustc-std-workspace-core` so these crates can remove their crates.io dependency in the future.
2025-03-17	replace config.toml to bootstrap.toml in src/ci, src/etc/* and tests/run-make	bit-aloo	-1/+1

2025-02-26	Support raw-dylib link kind on ELF	Noratrieb	-1/+3
	raw-dylib is a link kind that allows rustc to link against a library without having any library files present. This currently only exists on Windows. rustc will take all the symbols from raw-dylib link blocks and put them in an import library, where they can then be resolved by the linker. While import libraries don't exist on ELF, it would still be convenient to have this same functionality. Not having the libraries present at build-time can be convenient for several reasons, especially cross-compilation. With raw-dylib, code linking against a library can be cross-compiled without needing to have these libraries available on the build machine. If the libc crate makes use of this, it would allow cross-compilation without having any libc available on the build machine. This is not yet possible with this implementation, at least against libc's like glibc that use symbol versioning. The raw-dylib kind could be extended with support for symbol versioning in the future. This implementation is very experimental and I have not tested it very well. I have tested it for a toy example and the lz4-sys crate, where it was able to successfully link a binary despite not having a corresponding library at build-time.
2025-01-26	Downgrade `linker-warnings` to allow-by-default	jyn	-0/+1
	This needs more time to bake before we turn it on. Turning it on early risks people silencing the warning indefinitely, before we have the chance to make it less noisy.
2025-01-25	Shorten linker output even more when `--verbose` is not present	jyn	-11/+42
	- Don't show environment variables. Seeing PATH is almost never useful, and it can be extremely long. - For .rlibs in the sysroot, replace crate hashes with a `"-*"` string. This will expand to the full crate name when pasted into the shell. - Move `.rlib` to outside the glob. - Abbreviate the sysroot path to `<sysroot>` wherever it appears in the arguments. This also adds an example of the linker output as a run-make test. Currently it only runs on x86_64-unknown-linux-gnu, because each platform has its own linker arguments. So that it's stable across machines, pass BUILD_ROOT as an argument through compiletest through to run-make tests. - Only use linker-flavor=gnu-cc if we're actually going to compare the output. It doesn't exist on MacOS.
2025-01-20	Don't require `--verbose` to show linker stdout	jyn	-6/+1

2025-01-20	don't ICE when emitting linker errors during `-Z link-only`	jyn	-0/+29
	note that this still ICEs when passed `-Z link-only --error-format json` because i can't be bothered to fix it right now
2025-01-20	show linker warnings even if it returns 0	jyn	-0/+36

2024-12-14	don't show the full linker args unless `--verbose` is passed	jyn	-0/+42
	the linker arguments can be very long, especially for crates with many dependencies. some parts of them are not very useful. unless specifically requested: - omit object files specific to the current invocation - fold rlib files into a single braced argument (in shell expansion format) this shortens the output significantly without removing too much information.
