<pre>AsmParser::parseMacroLikeBody() contains
if (Lexer.is(AsmToken::Identifier) &&
(getTok().getIdentifier() == ".rept")) {
++NestLevel;
}
to support nested .rept blocks. This was added in
<a href="http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120528/143967.html">http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120528/143967.html</a>
The function is also used for .irp and .irpc though – since there's no check
for .irp and .irpc in that line, these can't be nested, and the three
directives can't be nested with each other either. Only .rept can be nested
with itself.
