Bug #: 56406
Summary: attribute((target(xpto))) causes ICE in i386 and
rs6000
Classification: Unclassified
Product: gcc
Version: 4.7.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: paulo@matos-sorge.com
While doing some tests I came across this ICE:
int __attribute__((__target__(xpto)))
foo(int x)
{
if (x == 1)
return x;
else
return x * foo (x-1);
}
If any word instead of xpto works. The compiler fails with:
internal compiler error: in ix86_valid_target_attribute_inner_p, at
config/i386/i386.c:4214
This is because it's expecting either a STRING_CST ("xpto") or a TREE_CHAIN. If
an identifier node is seen instead we hit a gcc_unreachable. The other backend
that should be affected by this (but I didn't reproduce it) is rs6000.
