Version: 4.7.0
Status: UNCONFIRMED
Severity: normal

Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ro@gcc.gnu.org
CC: davem@davemloft.net, ebotcazou@gcc.gnu.org
Host: sparc-sun-solaris2*

Between 20120103 and 20120113, the 64-bit 64-bit
gcc.target/sparc/vec-init1-vis1.c
test started to FAIL:

Excess errors:

On line 24, there is

Using gas instead, I get

'e' doesn't imply even-numbered though, there is no specific constraint for that. I think it's the long-standing issue with word-mode paradoxical subregs of FP regs in 64-bit mode, for which both the PA and the SPARC ports have a kludge, in the form of the CANNOT_CHANGE_MODE_CLASS macro. I'm going to kludge again for this one by tweaking vector_init_fpmerge a bit. ^ permalink raw reply [flat|nested] 6+ messages in thread
