Hi, everybody. I am a newbie in llvm development. I found some strange behaviour in llvm-mc. Files without empty string at the eof doesn't proceed properly. llvm-mc prints something like this: <stdin>:5:18: error: unexpected token in argument list It looks like a bug. At least we should print: <stdin>:5:18: error: no newline at the end of file! If yes, I create it in bugzilla and assign to myself. Thank you. P.S.: I attached file without newline at eof. Try to run "llvm-mc -triple=armv7-apple-darwin -show-encoding < test.s" -- Truly yours -------------- next part -------------- A non-text attachment was scrubbed...

A friendlier error message in that situation is definitely a good thing. -Jim On Sep 5, 2011, at 1:34 PM, Степан wrote:> Hi, everybody. > > I am a newbie in llvm development.

I created a bug (#10869: http://llvm.org/bugs/show_bug.cgi?id=10869) and I made the next patch for it: http://llvm.org/bugs/attachment.cgi?id=7235 By know it doesn't write any warnings, because AsmLexer cant send the warnings. llvm-mc just parses this type of files properly without any messages. Is it OK? What about lexer-side-warnings? If you need I can implement it. -- Truly yours, Stepan Dyatkovskiy 07.09.2011, 02:19, "Jim Grosbach" <grosbach at apple.com>:> A friendlier error message in that situation is definitely a good thing. > > -Jim > > On Sep 5, 2011, at 1:34 PM, Степан wrote: > >> Hi, everybody. >> >> I am a newbie in llvm development.
