2023-09-08Revert "add crate_root property to rust modules" Sam Delmerico
Revert submission 2605644-rulebuilder-ninja-vars Reason for revert: b/299568218 Reverted changes: /q/submissionid:2605644-rulebuilder-ninja-vars Change-Id: I17645fcff117909c09a016157235805f0974340b
2023-08-31add crate_root property to rust modules Sam Delmerico
The crate_root property will be used to specify the entry point for a rustc compilation. This will allow the srcs property to be used to collect all src inputs to rustc rather than just the entry point. Bug: 286077158 Test: m libnum_traits Change-Id: I1a167182305dcc11cc927d562ceed622153111d3
2023-08-16Merge "rust: Add support for host fuzzers." into main Ivan Lozano
2023-08-14Remove dylibs prop from rust module types Vinh Tran
For device build, rust defaults to dylib linkage for rustlibs deps. `dylibs` prop was provided for flexibility. By removing it, we're enforcing users to either use the default linkage (dylibs for device and rlibs for host) or rlibs prop explicitly. This means no dylibs for host modules. This makes sense because host modules always uses rlib linkage against libstd. The flexibility with dylibs prop opened room for linkage collisions because the dependencies don't link against libstd the same way. Test: go test Change-Id: I2fc221daa8a9bb42bdcf6d9823c723a4ddabe7b5

2023-02-14rust: Fix coverage in no-std crates Ivan Lozano
Coverage builds for no_std crates currently fail because profiler_builtins are part of libstd and therefore do not get included. When calculating the dependencies for coverage enabled targets, check if the stdlib is being included, and if it is not then pull the profiler_builtins sysroot. Bug: 249551848 Test: CLANG_COVERAGE=true NATIVE_COVERAGE_PATHS='*' make libtinyvec_nostd.rlib-std Change-Id: I73f89bddcb2d4d9c704cb3962ee39b73888c7f3f
2023-01-11Use the same rpaths for tests and binaries and cc and rust Colin Cross
Rust and cc binaries currently use $ORIGIN/lib64:$ORIGIN/../lib64 as the rpath, and cc tests add $ORIGIN/../../lib64:$ORIGIN/../../../$ORIGIN:$ORIGIN. This causes problems when a binary is included as test data in out/host/linux-x86/testcases/<test dir>/<CPU>/<test>, as the binaries can't find the libraries in out/host/linux-x86/lib64. Use the same rpath for test and binaries, and for cc and rust.

2021-11-09rust: Refactor stripped output file path Ivan Lozano
Rust installed files reside in "$MODULE_OUT/stripped/" when they are stripped, otherwise they reside in "$MODULE_OUT". However, other parts of Soong assume that installed files are always in $MODULE_OUT (cc_modules place *unstripped* files in $MODULE_OUT/unstripped). This notably causes problems when adding Rust modules as test data in AndroidMkDataPaths. When Rust modules are parsed by AndroidMkDataPaths, if they are stripped then they incorrectly get installed as test data with the path: <install_root>/<relative_install_path>/stripped/file. This CL refactors how we handle Rust stripped output such that the installed file always resides in $MODULE_OUT. Bug: 171710847 Test: Installed files now always reside in $MODULE_OUT Change-Id: I53a6ff57a0a5a55cd95ea78ae592ce22abfa20c9
2021-10-14Flag an error on empty rust module srcs Seth Moore
It's an error if a rust module's srcs is empty. Prior to this change the output was a panic that complains loudly about a slice error and nothing else. This change doesn't stop the panic, but at least adds a bit of context so devs who make a simple mistake can more easily fix it. Test: SOONG_GEN_RUST_PROJECT=1 m nothing Change-Id: Id7d8465d533413c3000699661222a53a7c8678f3
2021-09-23rust: Refactor cfg and feature flag calculation Ivan Lozano
Move the cfg and feature flag calculation out of compilerFlags so that it's a separate step. The previous arrangement resulted in overridden compilerFlags which must to set any additional cfgs/features before calling the base. This is a bit confusing and undocumented behavior, so instead break it out into a separate call that can itself be overriden. Bug: N/A Test: Soong tests pass Change-Id: I28e4f707b3b3ca6eb621b7613c3737817f877bb8
2021-08-20rust: Hook up InstallIn functions + Product Matthew Maurer
InstallIn functions must be hooked up not only to install to special images, but also to receive special handling by android/arch.go such that some images are implicitly multilib: first.

2021-08-12rust: Add support to emit certain Cargo env vars. Ivan Lozano
Some crates expect Cargo to provide certain environment variables. This CL adds a compatability flag that emulates the behavior of Cargo by setting these environment variables when building. Bug: 171011485 Test: New soong tests pass Test: quiche no longer requires patch removing CARGO_PKG_VERSION Change-Id: I4c95c284846f6075428c6f61fe8c260f2e35fbd9
2021-07-27rust: Prevent manually defined lib link flags. Ivan Lozano
Adds a filter to prevent modules from manually defining certain linkage flags. These flags should only be automatically generated based on listed dependencies. Bug: 161942165 Test: Soong tests pass Change-Id: Ibc014391ef1de10188c2d139d41d0241d6c68b5f

2021-05-12Refactor vendor snapshot to use LinkableInterface. Ivan Lozano
Refactors the vendor snapshot support to use the LinkableInterface so that support can be extended to Rust. This CL does not add vendor snapshot support for Rust; that is left for a follow-on CL. Bug: 184042776 Test: m nothing Change-Id: Id0c4970ca00053484a52677d182153cbc454c301

2021-04-08Merge "rust: Add cfgs property" Thiébaud Weksteen
2021-04-07Stripped rust bin/libs are included in APEX Jiyong Park
Previously, when a rust bin or library is selected for an APEX, OutputFile() was used to get the file to be used. However, OutputFile() always returns the unstripped output file even when the stripped output file is available. As a result, APEX having a rust module was very big due to the debugging information that exists in the unstripped file. When a rust module is directly installed to the built-in partitions, we use the stripped one whenever it's available. To make the same happen when the rust module is placed in an APEX, OutputFile() is modified to return the unstripped output if it's available. Bug: 181751814 Test: TARGET_BUILD_APPS=com.android.virt m The size is reduced from 180MB to 43MB Change-Id: I6f8479e6a4794aac8bf94a84afdf65d417c75db0
2021-04-07rust: Add cfgs property Thiébaud Weksteen
Rust configuration options ("--cfg") are currently defined using the "flags" property. Adds a specific property to be able to forward these to the rust-analyzer configuration (rust-project.json). Bug: 183727250 Test: m libstd Change-Id: Ida89097814bcd1a45c02a8a79ec5a8e9e59701bd
2021-03-25rust: Add whole_static_libs, revert static_lib Ivan Lozano
Revert the static_lib behavior to the previous behavior (pass static libs to the linker rather than via to rustc using `-lstatic=<lib>`). To bundle static libraries into libraries, provide the whole_static_libs property which retains the current static_libs behavior. Passing all static libraries via -lstatic was resulting in odd bloat where in some cases static symbols were duplicated in binaries and libraries. This split makes it possible to be explicit about when static libraries should be bundled. Bug: 183182230 Test: mma system/bt; mma system/security/keystore2; mma external/rust Change-Id: Ic2dde5d1542dca5ce145aa3a3fbd9ea54440d991
2021-03-23rust: Drop libgcc dependency Thiébaud Weksteen
Rustc unstable option "link-native-libraries" is used to prevent the linkage of other libraries via the #[link] directive. Add a dependency to libclang_rt.builtins, similarly to cc. Bug: 141331117 Test: lunch aosp_crosshatch-userdebug; m Change-Id: I5c232291a5dd08a99e6a12a1295e30bb8e4fcaf1
2021-03-15Export OUT_DIR variable to rust-project.json Thiébaud Weksteen
This variable is required by rust-analyzer to correctly process crates that uses the include!(concat!(env!("OUT_DIR"), ...)) pattern. Adds an initialize method to baseCompiler to save the computed path for this directory. It is not possible to use the BeginMutator as the BaseModuleContext does not contain enough information to use PathForModuleOut.

2021-02-12rust: Emit android vndk cfg flag. Ivan Lozano
Pass an "android_vndk" cfg flag that indicates this code targets the vndk. This can be useful in instances where code might need to behave differently. This also includes a fix to make sure our vendor Soong tests are correctly configured. Bug: 179907868 Test: Soong tests pass. Test: Example module emits new cfg flags.

2021-02-04rust: Pass cc static libs to rustc. Ivan Lozano
Pass static libraries to rustc via the "-lstatic" flag so that rustc can reason how to handle these libraries. This means that these static libraries get bundled into rlibs, reducing the need to redeclare these dependencies in dependent modules. Additionally, exported depFlags were never used anywhere, so remove this from flagExporter.

2020-12-09Move prefer_rlib from binary to base compiler. Ivan Lozano
Moves the prefer_rlib property out from being exclusively a binary property to one thats part of the base compiler properties. This provides a little more control over the libstd linkage in our libraries. Specifically, this enables a usecase where rust_ffi_shared needs to link against libstd statically rather than dynamically. Bug: 175121262 Test: New Soong tests pass.

2020-09-18rust: Add libstd linkage mutator for rlibs. Ivan Lozano
The current state of linkage is that device targets always link libstd dynamically except for rust_ffi_static which requires a static libstd linkage. However this prevents producing rust_ffi_static modules which depend on other Rust libraries as those dependencies will link libstd dynamically and cause a collision. We also want our rust_test modules to statically link in libstd as well. This adds a linkage mutator for rlibs that creates a variant for each libstd linkage. Dependent modules can then select the variant that matches their linkage of libstd. Also fixes an issue where installation paths were being generated for rlibs and static libs even though they weren't being installed. This broke when adding the linkage mutator as Make would complain about multiple targets producing the same output. Bug: 168729404 Test: rust_ffi_static module with other rustlib dependency can be built. Change-Id: I955b484bf5809e8fc5517750c7f8df82d3ca8895
