Hi,
Please find attached the patch “asm-subreg.patch” for aarch64 which
fixes ICE for /gcc.dg/torture/asm-subreg-1.c testcase.
The error was the result of reload problems in
“aarch64_load_symref_appropriately” function.
The higher part of symbol_ref moved to temporary RTX “tmp_reg” does
not contain the exact value. The dumps showed that (CONST_INT 0) is
moved into the temporary RTX.
When the higher part of symbol_ref was added with the temporary rtx
and moved into the “dest”, it seg faults due to reload issues.
Hence, the transfer of symbol_ref is handled slightly in a modified
manner which fixes the ICE.
Please review the patch and let me know your comments on the same.
You forgot to attach the patch.
Thanks,
Andrew Pinski
Not to mention the ChangeLog entry.
