… not call the managed JIT_GCPoll helper
Contributor
There was a problem hiding this comment.
Pull Request Overview
This PR fixes an infinite recursion issue in the CoreCLR interpreter's safepoint implementation. The problem occurs when using a pure interpreted environment where calling the managed JIT_GCPoll helper from INTOP_SAFEPOINT creates recursion since JIT_GCPoll itself is managed code.
Key changes:
- Replaces the managed
JIT_GCPoll()call with a direct GC transition usingGCX_PREEMP() - Adds explanatory comment about the purpose of the GC transition

The managed helper includes the GC poll within it, since JIT_GCPoll is itself managed, when we are in a pure interpreted environment, we will go into infinite recursion triggering the INTOP_SAFEPOINT code
