Subject: Remove unused variable spotted by GCC.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7d4b159c0e47f4e78e25cb298430be4fdf415bb7;p=clang

Remove unused variable spotted by GCC.

Devang, can we remove this call entirely? If I try that, "make check" passes
but the call has a side-effect of ensuring that the block's context exists in
the debug info. getContextDescriptor() is used in a void context for that side-
effect elsewhere in this file. Please take a look!
