Status: UNCONFIRMED
Severity: normal
Priority: P3

Target Milestone: ---
When some graphite (require the isl build for gcc) tests, there are sorts of
ICE that cannot recog the insn.

RISC-V: Fix ICE for legitimize move on subreg const_poly_int [PR114885]
When we build with isl, there will be a ICE for graphite in both
the c/c++ and fortran. The legitimize move cannot take care of
below rtl.
(set (subreg:DI (reg:TI 237) 8) (subreg:DI (const_poly_int:TI [4, 2]) 8))
Then we will have ice similar to below:
internal compiler error: in extract_insn, at recog.cc:2812.
This patch would like to take care of the above rtl. Given the value of
const_poly_int can hardly excceed the max of int64, we can simply
consider the highest 8 bytes of TImode is zero and then set the dest
to (const_int 0).
The below test cases are fixed by this PATCH.

The below test suites are passed for this patch:
* The rv64gcv fully regression test.
* The rv64gc fully regression test.
Try to write some RTL code for test but not works well according to
existing test cases. Thus, take above as test cases. Please note
graphite require the gcc build with isl.
