Currently, calling pow may panic in case of overflow, and the function does not have non-panicking counterparts. Thus, it would be beneficial to add those in.
Previously, if the gdb command was available, but threw an error, compiletest would panic. This is obviously not good. Now, gdb is treated as missing if calling `gdb --version` does not output anything on stdout.
Make a minimal commitment for stabilization. More impls are likely in future, but are not necessary at this time.
This ensures that the entry function is never elided due to inlining, even with `inline(always)`. Fixes rust-lang#47783. There were a couple of possible ways of addressing this issue; I simply picked the one that seemed most direct. A warning could be appropriate, but considering using inlining hints in other places it doesn't apply also throws no warnings, and it seems like an edge case anyway, I haven't added one for now.
This is what [Intel calls it][bmi1] and will [remove a special case][stdsimd] when verifying intrinsics in stdsimd.

…on-ice, r=michaelwoerister Report non-standard compile flags on ICE Some ICEs (such as the recent rust-lang#48248) only happens when a non-standard compiler flag is provided to rustc, but users don't always report the used flags. This can slow down reproducing the issue, so this PR shows all the non-standard compiler flags in the ICE error message. For example, the output of rust-lang#48248 with this PR is: ``` error: internal compiler error: [...] thread 'rustc' panicked at [...] note: Run with `RUST_BACKTRACE=1` for a backtrace. note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: [...] note: rustc 1.25.0-dev running on x86_64-unknown-linux-gnu note: compiler flags: -C link-dead-code ``` ### Open questions * At the moment, only `-C` and `-Z` flags are shown by default, and all the ones provided by cargo in a standard build are ignored: I did this to only show the flags that probably caused the ICE, and to remove some noise from the message. This removed flags like `opt-level` and `debuginfo` though, could those be useful for reproducing ICEs?
Add non-panicking variants of pow for integer types Currently, calling pow may panic in case of overflow, and the function does not have non-panicking counterparts. Thus, it would be beneficial to add those in. Closes rust-lang#48291. Relevant tracking issue: rust-lang#48320

…ichton Add support for powerpc-unknown-linux-gnuspe This PR adds support for the embedded PowerPC variant "e500". On Linux, this architecture is usually called "powerpcspe", it is a 32-bit PowerPC architecture. The main difference between normal 32-bit PowerPC and PowerPCSPE is the lack of Altivec instructions and the additional SPE instruction set. This architecture is supported in Debian through an unofficial port.
…, r=michaelwoerister Handle gdb command failure gracefully in compiletest Previously, if the gdb command was available, but threw an error, compiletest would panic. This is obviously not good. Now, gdb is treated as missing if calling `gdb --version` does not output anything on stdout.
…n, r=nikomatsakis Restrict the Termination impls to simplify stabilization Make a minimal commitment in preparation for stabilization. More impls, or broader ones, are likely in future, but are not necessary at this time and are more controversial. cc rust-lang#48453 (comment) r? @nikomatsakis
