[Bug c/32348] New: ICE on valid code

[edmar at freescale dot com]

Gcc version 4.2.0 configured for e500v2, i.e.:
--target=powerpc-unknown-linux-gnuspe --enable-e500_double

ICE occurs during build of eglic-2.5.

Here is the command with -v, attached is e_expl.i

glibc for Power requires IBM long double, and IBM long double for E500 is 
not supported by unmodified FSF GCC 4.2 (since my patch to add the support 
was large and depended on changes to target-independent RTL parts of the 
compiler that were potentially risky to other targets - and indeed did 
need followup patches to fix problems with other targets that showed up 
when those changes went on mainline).

If you are using a compiler with all the relevant changes backported, then 
GCC Bugzilla isn't the right place to report bugs in it.  Of course, if 
the bug still applies when building glibc (2.6 or later in order to work 
with newer GCC) with current unmodified GCC trunk, then report it here as 
a bug against trunk.

Edmar, can you confirm Joseph's suggestion?  Thanks.

Ben, this bug is almost 2 years old.
I don't remember what we did to resolve the issue.
I am surprised to find it is still open. I am going try to close it.

Edmar
