The test will fail on any hppa target with the addition of "-fPIC".

I tend to think the use of the 'X' constraint is bogus, and that the
test should be xfailed on hppa64.  While it might be possible to add
support to handle this particular reload, it's not something that's
needed for the patterns in pa.md.  As Kenner noted, combine doesn't
check that anything it generates is valid.

I think the PR can be closed.

------- Comment #36 from ghazi at gcc dot gnu dot org  2010-03-11 17:00 -------
I'm seeing failures for gcc.dg/torture/asm-subreg-1.c on
armv5tel-unknown-linux-gnueabi on mainline and 4.4/4.3 branches when using
-fpic or -fPIC and optimizing.  See:

http://gcc.gnu.org/ml/gcc-testresults/2010-03/msg00638.html

The error message is:

 > asm-subreg-1.c: In function 'evas_common_convert_yuv_420p_601_rgba':
 > asm-subreg-1.c:13:3: error: 'asm' operand requires impossible reload
 > compiler exited with status 1


Is this a bug or skip it like hppa?

hppa64-hpux is indeed the only target I now see this failing on on gcc-testresults.
