rs6000: cannot_force_const_mem for HIGH code rtx[PR106460]
As the issue in PR106460, a rtx 'high:DI (symbol_ref:DI ("var_48")' is
tried
to store into constant pool and ICE occur. But actually, this rtx
represents
partial incomplete address and can not be put into a .rodata section.
This patch updates rs6000_cannot_force_const_mem to return true for rtx(s)
with
HIGH code, because these rtx(s) indicate part of address and are not ok for
constant pool.
Below are some examples:
(high:DI (const:DI (plus:DI (symbol_ref:DI ("xx") (const_int 12 [0xc])
(high:DI (symbol_ref:DI ("var_1")..)))
PR target/106460
gcc/ChangeLog:
* config/rs6000/rs6000.cc (rs6000_cannot_force_const_mem): Return
true
for HIGH code rtx.
gcc/testsuite/ChangeLog:
* gcc.target/powerpc/pr106460.c: New test.
