Re: ARM targetted gcc hangs

[Scott Bambrough <scottb at netwinder dot org>]

This problem has been reported before.  A description and analysis is available
at:

http://gcc.gnu.org/ml/gcc-bugs/1999-06/msg00853.html

It is still a problem in all ARM versions including gcc 2.95.2 and the current
arm-thumb branch in CVS.  I haven't tried the main line, but I can't imagine it
will be any different.  BTW, if anyone is interested I keep a record of known
ARM related compiler bugs at:
