Hi,
Please find attached the patch âasm-subreg.patchâ for aarch64 which
fixes ICE for /gcc.dg/torture/asm-subreg-1.c testcase.
The error was the result of reload problems in
âaarch64_load_symref_appropriatelyâ function.
The higher part of symbol_ref moved to temporary RTX âtmp_regâ 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 âdestâ, 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.
