Bug ID: 109725 Summary: [14 Regression] ICE: RTL check: expected code 'const_int', have 'reg' in riscv_print_operand, at config/riscv/riscv.cc:4430 Product: gcc Version: 14.0 Status: UNCONFIRMED Keywords: build, ice-on-valid-code Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: zsojka at seznam dot cz Target Milestone: --- Host: x86_64-pc-linux-gnu Target: riscv64-unknown-linux-gnu RTL checking might need to be enabled. This currently breaks build with RTL checking enabled.
