Consequently, an rtx such as: (set (reg/i:DI 0 x0) (unspec:DI [(const_string ("s3_3_c13_c2_2"))]) can now be output correctly using the following output pattern when composing `define_insn's: "mrs\t%x0, %1" Testing: - Bootstrap/regtest on aarch64-linux-gnu done. gcc/ChangeLog * config/aarch64/aarch64.cc (aarch64_print_operand): Add support for CONST_STRING. --- gcc/config/aarch64/aarch64.cc | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/gcc/config/aarch64/aarch64.cc b/gcc/config/aarch64/aarch64.cc index 62b1ae0652f..c715f6369bc 100644 --- a/gcc/config/aarch64/aarch64.cc +++ b/gcc/config/aarch64/aarch64.cc @@ -12346,6 +12346,11 @@ aarch64_print_operand (FILE *f, rtx x, int code) switch (GET_CODE (x)) { + case CONST_STRING: + { + asm_fprintf (f, "%s", XSTR (x, 0)); + break; + } case REG: if (aarch64_sve_data_mode_p (GET_MODE (x))) {
