# 0834a4b9	19-Sep-2013	Eli Friedman <eli.friedman@gmail.com>	Make Preprocessor::Lex non-recursive. Before this patch, Lex() would recurse whenever the current lexer changed (e.g. upon entry into a macro). This patch turns the recursion into a loop: the variou Make Preprocessor::Lex non-recursive. Before this patch, Lex() would recurse whenever the current lexer changed (e.g. upon entry into a macro). This patch turns the recursion into a loop: the various lex routines now don't return a token when the current lexer changes, and at the top level Preprocessor::Lex() now loops until it finds a token. Normally, the recursion wouldn't end up being very deep, but the recursion depth can explode in edge cases like a bunch of consecutive macros which expand to nothing (like in the testcase test/Preprocessor/macro_expand_empty.c in this patch). <rdar://problem/14569770> llvm-svn: 190980 show more ...
