--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Kito Cheng <k...@gcc.gnu.org>: https://gcc.gnu.org/g:6547906bdbdb3feb0d3bd96e09ceffcbc489349f commit r14-11554-g6547906bdbdb3feb0d3bd96e09ceffcbc489349f Author: Jeff Law <j...@ventanamicro.com> Date: Mon Dec 30 13:51:55 2024 -0700 [RISC-V][PR target/106544] Avoid ICEs due to bogus asms This is a fix for a bug Andrew P filed a while back where essentially a poorly crafted asm statement could trigger a ICE during assembly output. Various cases will use INTVAL (op) without verifying the operand is a CONST_INT node first. The usual way to handle this is via output_operand_lossage, which this patch implements. I focused primarily on the CONST_INT cases, there could well be other problems in this space, if so they should get distinct bugs with testcases. Tested in my tester on rv32 and rv64. Waiting for pre-commit testing before moving forward. PR target/106544 gcc/ * config/riscv/riscv.cc (riscv_print_operand): Issue an error for invalid operands rather than invalidly accessing INTVAL of an object that is not a CONST_INT. Fix one error string for 'N'. gcc/testsuite * gcc.target/riscv/pr106544.c: New test.
