2022-08-09Pass +atomics-32 feature for thumbv6m targetNikita Popov-1/+3
https://reviews.llvm.org/D120026 changed atomics on thumbv6m to use libatomic, to ensure that atomic load/store are compatible with atomic RMW/CAS. However, Rust wants to expose only load/store without libcalls. https://reviews.llvm.org/D130480 added support for this behind the +atomics-32 target feature, so enable that feature.
2022-07-24Revert "Mark atomics as unsupported on thumbv6m"Amanieu d'Antras-2/+1
This reverts commit 75146102197c7f35e6c38cb402b2bc1065858c54.
2022-07-22Mark atomics as unsupported on thumbv6mNikita Popov-1/+2
The thumbv6m target does not support atomics. Historically, LLVM had a bug where atomic load/stores for this target were emitted as plain load/stores rather than as libatomic calls. This was fixed in https://reviews.llvm.org/D120026, which will be part of LLVM 15. As we require that "atomic support" does not use libatomic, we need to indicate that this target does not have native atomics.

2021-07-07Update targets to use target_abiJosh Triplett-0/+1
All eabi targets have target_abi = "eabi". All eabihf targets have target_abi = "eabihf". armv6_unknown_freebsd and armv7_unknown_freebsd have target_abi = "eabihf". All abi64 targets have target_abi = "abi64". All ilp32 targets have target_abi = "ilp32". All softfloat targets have target_abi = "softfloat". All *-uwp-windows-* targets have target_abi = "uwp". All spe targets have target_abi = "spe". All macabi targets have target_abi = "macabi". aarch64-apple-ios-sim has target_abi = "sim". x86_64-fortanix-unknown-sgx has target_abi = "fortanix". x86_64-unknown-linux-gnux32 has target_abi = "x32". Add FIXME entries for targets for which existing values need to change once cfg_target_abi becomes stable. (All of them are tier 3 targets.) Add a test for target_abi in `--print cfg`.

2020-10-15Use integer literals for builtin target_pointer_width fieldsest31-1/+1
Also change target_pointer_width to pointer_width. Preparation for a subsequent type change of target_pointer_width to an integer together with a rename to pointer_width. On its own, this commit breaks the build. I don't like making build-breaking commits, but in this instance I believe that it makes review easier, as the "real" changes of this PR can be seen much more easily. Result of running: find compiler/rustc_target/src/spec/ -type f -exec sed -i -e 's/target_pointer_width: "\(.*\)"\..*,/pointer_width: \1,/g' {} \;
2020-10-05rustc_target: Refactor away `TargetResult`Vadim Petrochenkov-4/+4
Construction of a built-in target is always infallible now, so `TargetResult` is no longer necessary.
