more complete sparc64 ABI fix for aggregates with floating point members Previous fix didn't handle nested structures at all.

2022-02-21Take CodegenFnAttrs into account when validating asm! register operandsAmanieu d'Antras-120/+94
Checking of asm! register operands now properly takes function attributes such as #[target_feature] and #[instruction_set] into account.
2022-02-21On ARM, use relocation_model to detect whether r9 should be reservedAmanieu d'Antras-44/+58
The previous approach of checking for the reserve-r9 target feature didn't actually work because LLVM only sets this feature very late when initializing the per-function subtarget.

Adopt let else in more places Continuation of #89933, #91018, #91481, #93046, #93590, #94011. I have extended my clippy lint to also recognize tuple passing and match statements. The diff caused by fixing it is way above 1 thousand lines. Thus, I split it up into multiple pull requests to make reviewing easier. This is the biggest of these PRs and handles the changes outside of rustdoc, rustc_typeck, rustc_const_eval, rustc_trait_selection, which were handled in PRs #94139, #94142, #94143, #94144.

Add MemTagSanitizer Support Add support for the LLVM [MemTagSanitizer](https://llvm.org/docs/MemTagSanitizer.html). On hardware which supports it (see caveats below), the MemTagSanitizer can catch bugs similar to AddressSanitizer and HardwareAddressSanitizer, but with lower overhead. On a tag mismatch, a SIGSEGV is signaled with code SEGV_MTESERR / SEGV_MTEAERR. # Usage `-Zsanitizer=memtag -C target-feature="+mte"` # Comments/Caveats * MemTagSanitizer is only supported on AArch64 targets with hardware support * Requires `-C target-feature="+mte"` * LLVM MemTagSanitizer currently only performs stack tagging. # TODO * Tests * Example

Apply noundef attribute to &T, &mut T, Box<T>, bool This doesn't handle `char` because it's a bit awkward to distinguish it from `u32` at this point in codegen. Note that this _does not_ change whether or not it is UB for `&`, `&mut`, or `Box` to point to undef. It only applies to the pointer itself, not the pointed-to memory.

2022-02-08add kernel target for RustyHermitStefan Lankes-0/+17
Currently, we are thinking to use *-unknown-none targets instead to define for every platform our own one (see hermitcore/rusty-hermit#197). However, the current target aarch64-unknown-none-softfloat doesn't support dynamic relocation. Our kernel uses this feature and consequently we define a new target aarch64-unknown-hermitkernel to support it.

2022-02-06Rollup merge of #92383 - lancethepants:armv7-unknown-linux-uclibceabi, r=nagisaMatthias Krüger-0/+24
Add new target armv7-unknown-linux-uclibceabi (softfloat) This adds the new target `armv7-unknown-linux-uclibceabi (softfloat)`. It is of course similar to `armv7-unknown-linux-uclibceabihf (hardfloat)` which was just recently added to rust except that it is `softfloat`. My interest lies in the Broadcom BCM4707/4708/BCM4709 family, notably found in some Netgear and Asus consumer routers. The armv7 Cortex-A9 cpus found in these devices do not have an fpu or NEON support. With this patch I've been able to bootstrap rustc, std and host tools `(extended = true)` to run on the target device for native compilation, allowing the target to be used as a development platform. With the recent addition of `armv7-unknown-linux-uclibceabihf (hardfloat)` it looks like many of the edge cases of using the uclibc c-library are getting worked out nicely. I've been able to compile some complex projects. Some patching still needed in some crates, but getting there for sure. I think `armv7-unknown-linux-uclibceabi` is ready to be a tier 3 target. I use a cross-toolchain from my project to bootstrap rust. https://github.com/lancethepants/tomatoware The goal of this project is to create a native development environment with support for various languages.

2022-02-05Apply noundef attribute to &T, &mut T, Box<T>, boolErik Desjardins-1/+6
This doesn't handle `char` because it's a bit awkward to distinguish it from u32 at this point in codegen. Note that for some types (like `&Struct` and `&mut Struct`), we already apply `dereferenceable`, which implies `noundef`, so the IR does not change.

2022-02-01Rollup merge of #86374 - bossmc:enable-static-pie-for-gnu, r=nagisaMatthias Krüger-0/+1
Enable combining `+crt-static` and `relocation-model=pic` on `x86_64-unknown-linux-gnu` Modern `gcc` versions support `-static-pie`, and `rustc` will already fall-back to `-static` if the local `gcc` is too old (and hence this change is optimistic rather than absolute). This brings the `-musl` and `-gnu` targets to feature compatibility (albeit with different default settings). Of note a `-static` or `-static-pie` binary based on glibc that uses NSS-backed functions (`gethostbyname` or `getpwuid` etc.) need to have access to the `libnss_X.so.2` libraries and any of their dynamic dependencies. I wasn't sure about the `# only`/`# ignore` changes (I've not got a `gnux32` toolchain to test with hence not also enabling `-static-pie` there).

- Fix style errors. - L4-bender does not yet support dynamic linking. - Stack unwinding is not yet supported for x86_64-unknown-l4re-uclibc. For now, just abort on panics. - Use GNU-style linker options where possible. As suggested by review: - Use standard GNU-style ld syntax for relro flags. - Use standard GNU-style optimization flags and logic. - Use standard GNU-style ld syntax for --subsystem. - Don't read environment variables in L4Bender linker. Thanks to CARGO_ENCODED_RUSTFLAGS introduced in #9601, l4-bender's arguments can now be passed from the L4Re build system without resorting to custom parsing of environment variables.

2022-01-06sess/cg: re-introduce split dwarf kindDavid Wood-1/+1
In #79570, `-Z split-dwarf-kind={none,single,split}` was replaced by `-C split-debuginfo={off,packed,unpacked}`. `-C split-debuginfo`'s packed and unpacked aren't exact parallels to single and split, respectively. On Unix, `-C split-debuginfo=packed` will put debuginfo into object files and package debuginfo into a DWARF package file (`.dwp`) and `-C split-debuginfo=unpacked` will put debuginfo into dwarf object files and won't package it. In the initial implementation of Split DWARF, split mode wrote sections which did not require relocation into a DWARF object (`.dwo`) file which was ignored by the linker and then packaged those DWARF objects into DWARF packages (`.dwp`). In single mode, sections which did not require relocation were written into object files but ignored by the linker and were not packaged. However, both split and single modes could be packaged or not, the primary difference in behaviour was where the debuginfo sections that did not require link-time relocation were written (in a DWARF object or the object file). This commit re-introduces a `-Z split-dwarf-kind` flag, which can be used to pick between split and single modes when `-C split-debuginfo` is used to enable Split DWARF (either packed or unpacked).
