Backport of #91216 to release/8.0

Customer Impact

Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by

  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL

Testing

Local testing:

  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:

Backport of #91216 to release/8.0
/cc @fanyang-mono
Customer Impact
Prior to this PR, the customer might hit an assertion or a SIGSEGV, when using UnsafeAccessor with full AOT. This PR fixes those issues by
  1. Skip type parameter check, when it is a wrapper of WRAPPER_SUBTYPE_UNSAFE_ACCESSOR
  2. Only encode when member_name is not NULL
Testing
Local testing:
  • Prior to this PR, full aot compilation for UnsafeAccessorsTests.dll encountered an assertion:
