Summary: libffi fails building for cris-elf
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libffi
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: hp@gcc.gnu.org
Target: cris-axis-elf
When support for CRIS v32 was added to the CRIS port, a "v32" multilib was
added to cris-elf. Unfortunately, libffi wasn't updated, resulting in build
failure for the whole of gcc without special configure options:

`push'
A temporary fix is to disable libffi for cris-elf. (No other action should be
necessary: cris-linux doesn't have a v32 multilib and the crisv32-* tuples
aren't matched by libffi configure.)
The correct fix is not that hard; there's a common assembly-language subset
used in other assembly codes, for example newlib+libgloss.
E.g. push R -> subq 4,$sp / move.d R,[$sp]
(equivalent in function, size and cycles except when condition codes need to be
preserved.)
I'll fix this the temporary way, then suspend the PR.
