<pre>test.S:
.4byte ~foo
#include "foo.h"
foo.h: is an empty file.
Then run:
$ clang -cc1as -filetype obj -main-file-name test.S -dwarf-version=4
-fdebug-compilation-dir /home/pmatos/Clients/embecosm/BUGS/b447/asm-lineno
-mrelocation-model static -dwarf-version=4 -o test.o test.s
test.S:-2:8: error: expected relocatable expression
.4byte ~foo
^
I very much doubt there's a line -2 in the file.
However, I know what the problem is. At this point the parsing of the asm has
finished. However the error handler calls DiagHandler which assumes the parsing
is ongoing and uses CppHashLoc variables. These variable are however of no more
use because they all now point to the last Hash line seen in the file, not the
one before the error.
I will submit a patch to fix this soon.</pre>
