Bug ID: 20431
Summary: `getTok().getIdentifier() == ".rept"` check in
AsmParser::parseMacroLikeBody() looks wrong
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: MC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
AsmParser::parseMacroLikeBody() contains
if (Lexer.is(AsmToken::Identifier) &&
(getTok().getIdentifier() == ".rept")) {
++NestLevel;
}
to support nested .rept blocks. This was added in
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120528/143967.html
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.
>From svn history, this looks like an oversight, not like a conscious decision.
