- Compatible with Emscripten 1.38.46-upstream or later upstream.
- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the old incorrect wasm32 C call ABI with the correct one,
preserving the old one as wasm32_bindgen_compat for wasm-bindgen
compatibility.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.
compiletest: Match suffixed environments
This fixes a case where an `ignore-musl` test was not ignored on
`armv7-unknown-linux-musleabihf` because the environment did not exactly
match. Only enforce that the environment starts with the argument to
`ignore-`.

Allow checking of run-pass execution output in compiletest
Closes#63751
Adds a `check-run-results` flag to compiletest headers, which if enabled checks the output of the execution of a run-pass test's binary against expected output.
The remote-test-client outputs a message of the form "uploaded
"<build_dir>/<executable_path>", waiting for result" onto stdout when
executing a test, which is then captured in the process result. This needs to be removed when
comparing the results of the run-pass test execution.
Ignores run-pass tests with the `check-run-results` flag enabled for the
wasm32-bare ("wasm32-unknown-unknown") target, as it does not support
printing to stdout/stderr.
use the code generation parameter -Clinker (same parameter as rustc)
to control what linker to use for building the rustdoc test executables.
closes: #63816
- Don't add path_buf_capacity feature.
- Convert `find_cdb` to early return style, reducing indentation
- Simplify `compute_stamp_hash` for CDB to just hash it's path, if any.
Several Microsoft debuggers (VS, VS Code, WinDbg, CDB, ...) consume the `*.natvis` files we embed into rust `*.pdb` files.
While this only tests CDB, that test coverage should help for all of them.
CHANGES
src\bootstrap
- test.rs: Run CDB debuginfo tests on MSVC targets
src\test\debuginfo
- issue-13213.rs: CDB has trouble with this, skip for now (newly discovered regression?)
- pretty-std.rs: Was ignored, re-enable for CDB only to start with, add CDB tests.
- should-fail.rs: Add CDB tests.
src\tools\compiletest:
- Added "-cdb" option
- Added Mode::DebugInfoCdb ("debuginfo-cdb")
- Added run_debuginfo_cdb_test[_no_opt]
- Renamed Mode::DebugInfoBoth -> DebugInfoGdbLldb ("debuginfo-gdb+lldb") since it's no longer clear what "Both" means.
- Find CDB at the default Win10 SDK install path "C:\Program Files (x86)\Windows Kits\10\Debugger\*\cdb.exe"
- Ignore CDB tests if CDB not found.
ISSUES
- `compute_stamp_hash`: not sure if there's any point in hashing `%ProgramFiles(x86)%`
- `OsString` lacks any `*.natvis` entries (would be nice to add in a followup changelist)
- DSTs (array/string slices) which work in VS & VS Code fail in CDB.
- I've avoided `Mode::DebugInfoAll` as 3 debuggers leads to pow(2,3)=8 possible combinations.
REFERENCE
CDB is not part of the base Visual Studio install, but can be added via the Windows 10 SDK:
https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk
Installing just "Debugging Tools for Windows" is sufficient.
CDB appears to already be installed on appveyor CI, where this changelist can find it, based on it's use here:
0ffc573110/appveyor.yml (L227)
