Add v0 symbol mangling for f16
and f128
#123816
Conversation
This should probably have a test, what does this need to look like? @rustbot label +F-f16_and_f128 |
In our demangler i have added these tests: https://github.com/rizinorg/rz-libdemangle/pull/65/files#diff-2714036a391c793a3dc93f3a3194c9d3998b9af31cc717a026e43058cd5b5e99R75-R78 |
That is awesome, thanks for being on the cutting edge of Rust demangling. It really is helpful to know that these changes work. |
Thanks for opening the PR! Yes, tests will be needed. There are UI tests in https://github.com/rust-lang/rust/blob/master/tests/ui/symbol-names. I'm a bit surprised that the test case for simple types does not test seem to test v0 mangling at all. It would be best to fix that. Let me know if you get stuck, then I can look into updating the existing tests in a separate PR. |

It seems that the test case parser cannot deal with rust/src/tools/compiletest/src/errors.rs Line 121 in 63f70b3

Missed that comment, thanks! Really had me confused. Opened #124137 to fix this |
@tgross35, if you want to make progress with this PR, independently of what the fix for compiletest turns out to be, I'd suggest to just rename the |
That's my plan if #124137 doesn't land before I circle back to this. Do the changes look fine, assuming I get the tests to actually pass? I probably also have to change |

@rustbot label +beta-nominated Nominating the first commit of this PR (809b84e) for beta backport as not having it in stage0 is blocking updates to compiler-builtins #125016. Only the first commit since the second adds tests that depend on a rustc-demangle update (part of #124213, which is much larger). Unsure what the policy is for this kind of less essential update so I asked on Zulip. Risk is qutie low so figure it doesn't hurt to ask. |
