[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ run-pass`
Fix two const-eval issues related to i128 negation First issue here was the fact that we’d only allow negating integers in i64 range in case the integer was not infered yes. While this is not the direct cause of the issue, its still good to fix it. The real issue here is the code handling specifically the `min_value` literals. While I128_OVERFLOW has the expected value (0x8000_..._0000), match using this value as a pattern is handled incorrectly by the stage1 compiler (it seems to be handled correctly, by the stage2 compiler). So what we do here is extract this pattern into an explicit `==` until the next snapshot. Fixes #38987 2017-01-11 16:28:23 +02:00			`fn main() {`
