[kdy1]

STR

1. git clone -b typescript https://github.com/kdy1/swc && (cd swc && git checkout 4d64b3eb5040c5ef9d2d42e93a98e76b9999f24f)

2. Modify swc/.cargo/config to

[build]
rustflags = [
    "--cfg", "procmacro2_semver_exempt",
    "-Z", "time-passes"
]
 
rustdocflags = [
    "--cfg", "procmacro2_semver_exempt",
]

3. cd swc/typescript/checker && cargo check

[jonas-schievink]

Did you try other nightlies as well?

Did you try other nightlies as well?

I tried 2019-06-11. It was same.

BTW, I somehow reduced it to 180 seconds. I changed code not to depend on nll.

[kdy1]

@jonas-schievink I tested on nightly-04-29, and it works like a charm.

That's a9ec99f...372be4f.

It seems likely this is related to #60444 which is being fixed in #61754.

[nikomatsakis]

I can confirm that it is fixed by #61754 (I tested locally)

I'm not getting the same output as OP(maybe I did it wrong, eg. I had to rename /tmp/swc/rust-toolchain2 so it wouldn't use another rustc/nightly 10june2019), however, previously:

/tmp/swc/typescript/checker 
$ cargo clean;time cargo check
...
    Finished dev [unoptimized + debuginfo] target(s) in 7m 47s

real	7m47.415s
user	9m34.483s
sys	0m9.290s

and after that PR:

/tmp/swc/typescript/checker 
$ cargo clean;time cargo check
...
    Finished dev [unoptimized + debuginfo] target(s) in 56.49s

real	0m56.524s
user	3m22.288s
sys	0m10.631s

[mati865]

#61754 was merged, @kdy1 can you retest latest nightly?

[kdy1]

@mati865 I tested it and it is fast again. Closing.
