Previously, only the end of pass RSS was indicated. This could easily lead one to believe that the change in RSS from one pass to the next was attributable to the second pass, when in fact it occurred between the end of the first pass and the start of the second. Also, improve alignment of columns.
…jorn3 Sync rustc_codegen_cranelift The highlight of this sync are abi compatibility with cg_llvm allowing mixing of cg_clif and cg_llvm compiled crates and switching to the x64 cranelift backend based on the new backend framework. r? ``@ghost`` ``@rustbot`` label +A-codegen +A-cranelift +T-compiler
This commit adds a new ABI to be selected via `extern "C-cmse-nonsecure-call"` on function pointers in order for the compiler to apply the corresponding cmse_nonsecure_call callsite attribute. For Armv8-M targets supporting TrustZone-M, this will perform a non-secure function call by saving, clearing and calling a non-secure function pointer using the BLXNS instruction. See the page on the unstable book for details. Signed-off-by: Hugues de Valon <hugues.devalon@arm.com>
This reverts commit bfcf97b. It causes a "can't resolve symbol" crash on macOS
FreeBSD doesn't have /bin/bash
Test FreeBSD on CI
It causes a miscompilation of lewton Fixes rust-lang#1142
This improves compilation time and shrinks the linked backend from 13MB to 9.7MB on Linux.
Use dynamic dispatch for the inner Module
…=m-ou-se Stabilize str_split_once Closes rust-lang#74773
This prevents an expensive Cranelift pass from running to reconstruct the debuginfo

…jorn3 Sync rustc_codegen_cranelift The main highlight of this sync is removal of support for the old x86 Cranelift backend. This made it possible to use native atomic instructions rather than hackishly using a global mutex. 128bit integer support has also seen a few bugfixes and performance improvements. And finally I have formatted everything using the same rustfmt config as the rest of this repo. r? `@ghost` `@rustbot` label +A-codegen +A-cranelift +T-compiler
