Some tests expect to be compiled for a specific CPU or require certain
target features to be present (or absent). These tests work fine with
default CPUs but fail in downstream builds for RHEL and Fedora, where
we use non-default CPUs such as z13 on s390x, pwr9 on ppc64le, or
x86-64-v2/x86-64-v3 on x86_64.

An inline asm terminator defines outputs along its target edges -- a
fallthrough target and labeled targets. Code generation implements this
by inserting code directly into the target blocks. This approach works
only if the target blocks don't have other predecessors.
Establish required invariant by extending existing code that breaks
critical edges before code generation.
Create a generic AVR target: avr-none2025-02-19T18:01:51+00:00Patryk Wychowaniecpwychowaniec@pm.me2024-10-13T12:58:44+00:00urn:sha1:78ddabf31d3147a19be77c3b38b49fe60915d75a
This commit removes the `avr-unknown-gnu-atmega328` target and replaces
it with a more generic `avr-none` variant that must be specialized with
the `-C target-cpu` flag (e.g. `-C target-cpu=atmega328p`).
Rollup merge of #136217 - taiki-e:csky-asm-flags, r=Amanieu2025-02-13T01:09:58+00:00Jacob Prattjacob@jhpratt.dev2025-02-13T01:09:58+00:00urn:sha1:0de2341fefd17bd48809f06a3bed2d5d2074cbd4
Mark condition/carry bit as clobbered in C-SKY inline assembly
C-SKY's compare and some arithmetic/logical instructions modify condition/carry bit (C) in PSR, but there is currently no way to mark it as clobbered in `asm!`.
This PR marks it as clobbered except when [`options(preserves_flags)`](https://doc.rust-lang.org/reference/inline-assembly.html#r-asm.options.supported-options.preserves_flags) is used.

> Under user mode, condition/carry bit (C) is located in the lowest bit of PSR, and it can be
accessed and changed by common user instructions. It is the only data bit that can be visited
under user mode in PSR.
> Condition or carry bit represents the result after one operation. Condition/carry bit can be
clearly set according to the results of compare instructions or unclearly set as some
high-precision arithmetic or logical instructions. In addition, special instructions such as
DEC[GT,LT,NE] and XTRB[0-3] will influence the value of condition/carry bit.
