[VS Code Extension] The LSP Fails and Crashes the ISPC Extension

[RoyiAvital]

On VS Code 1.99.1 with the latest version of ISPC (1.1.1) from March 2019.
Working on Windows 11 24H2.

When the extension loads I get the following:

WARN: server does not support a notification '$/setTraceNotification'
WARN: server does not support a notification '$/setTraceNotification'
WARN: server does not support a notification '$/setTraceNotification'
WARN: server does not support a notification '$/setTraceNotification'

The workaround for this issue is to open the extension settings and specify the fully qualified path to the compiler.

In the meantime 2 developers of Text Editors were kind to add support at my request:

• CudaText: [Feature Request] Language Support for ISPC (Intel Implicit SPMD Program Compiler) Alexey-T/CudaText#5944.
• ECoder: [Feature Request] Language Support for ISPC (Intel Implicit SPMD Program Compiler) SpartanJ/ecode#436 (At nightly).

I hope SublimeText will add support (sublimehq/Packages#4232) as well.

Thanks for doing that @RoyiAvital! That's awesome!

Did providing the fully qualified path in the extension settings not work?

I did not try it. I prefer waiting for the support of the binary in the path.
