Subject: [MS ABI] Cleanup get*ForUnnamedTagDecl
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=883b9addbbf6e898b0f34b78b9ca19ade04af6c9;p=clang

[MS ABI] Cleanup get*ForUnnamedTagDecl

Use "lookup" instead of operator[], it will not perform unnecessary
insertions.  No functionality change is intended.
