Mark loads from globals generated by cton_wasm or by legalization as
`aligned` and `notrap`, since memory for these globals should be
allocated by the runtime environment for that purpose. This reduces
the number of potentially trapping instructions, which can reduce
the amount of metadata required by embedding environments.
* cton-util: fix some clippy unnecessary pass-by-value warnings
* clippy: ignore too many arguments / cyclomatic complexity in module
since these functions are taking args coming from the command line, i
dont think this is actually a valid lint, morally the arguments are all
from one structure
* cton-util: take care of remaining clippy warnings
* cton-reader: fix all non-suspicious clippy warnings
* cton-reader: disable clippy at site of suspicious lint
* cton-frontend: disable clippy at the site of an invalid lint
* cton-frontend: fix clippy warnings, or ignore benign ones
* clippy: ignore the camelcase word WebAssembly in docs
* cton-wasm: fix clippy complaints or ignore benign ones
* cton-wasm tests: fix clippy complaints
* cretonne: starting point turns off all clippy warnings
* cretonne: clippy fixes, or lower allow() to source of problem
* cretonne: more clippy fixes
* cretonne: fix or disable needless_lifetimes lint
this linter is buggy when the declared lifetime is used for another type
constraint.
* cretonne: fix clippy complaint about Pass::NoPass
* rustfmt
* fix prev minor api changes clippy suggested
* add clippy to test-all
* cton-filetests: clippy fixes
* simplify clippy reporting in test-all
* cretonne: document clippy allows better
* cretonne: fix some more clippy lints
* cretonne: fix clippy lints (mostly doc comments)
* cretonne: allow all needless_lifetimes clippy warnings
remove overrides at the false positives
* rustfmt
Merge the `use` parts of the `no_std` branch. This reduces the diffs
between master and the `no_std` branch, making it easier to maintain.
Most of these changes are derived from patches by @lachlansneff in
https://github.com/Cretonne/cretonne/tree/no_std.
This will allow wasm implementations that wish to insert code into
every loop, for example to insert an interrupt check or a safepoint.
do so without relying on asynchronous signals.
The reserved register heaps are not implemented in the Cretonne
legalizer, so IR generated by the dummy environment would trip
assertions when compiled.
Use a heap with a vmctx base address instead, and also demonstrate how
vmctx arguments are added to all signatures to achieve this.
