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. Regards, Naveen
