New Revision: 133761
URL: http://llvm.org/viewvc/llvm-project?rev=133761&view=rev
Log:
Apparently at some point in the past I forgot how 'continue'
works in a 'while(false)' loop. Simplify this code; it was
complicated only in anticipation of C++0x lambdas, and it can
become complicated again when those happen. :)
