Subject: [llvm-commits] [PATCH] fix a bug in TableGen

Hi, Folks

This is a bug-fix patch to TableGen on TD files previously working from 2.8 to 3.0 but failed in trunk. I figured out that #NAME# resolving has been changed to reuse record field value resolving by adding NAME as a standard field. With a two-level multiclasses and both with #NAME#, the trunk code runs into infinite recursion. This patch fixes this issue by skipping re-calculating NAME when we found NAME is changed and skip resolving the field if it's the same as the specified one to be against.

The patch also includes a test case for regression test.

This patch passed 'make check ' on trunk code (r152136).

Yours
- Michael
