Subject: Alias code
Date: Mon, 29 Jun 1998 03:22:00 -0000 [thread overview]
Message-ID: <12751.899115510@hurl.cygnus.com> (raw)
We've got a little problem.
While the machine independent code is mostly free of gen_rtx (MEM)
calls, many of the target files, and some of the front-ends that we
want to interoperate (but possibly do not control) with are not free
of such calls.
I think we need to handle these cases in a clean manner. ie, we
have to initialize the alias set field when we allocate the MEM or
REG expression
Thoughts?

ps. i just spent 3hrs tracking down a case where the compiler would
mis-compile a testcase, but not if you turned on -g or certain debug
dumps -- it was tracked down to a call to gen_rtx (MEM) in a target
config file. I don't want to have to do this very often :(
