Bug ID: 110821
   Summary: gcc inline asm for the riscv architecture with the BNE
(and possibly other instructions)
   Product: gcc
   Version: 14.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: devnexen at gmail dot com
  Target Milestone: ---

Hi, sorry I'm new here I assume 14.0 means master ?
Anyway it seems there is a bug with risc-v architecture (tried with 32 bits)
with the bne instruction
(https://riscv.org/wp-content/uploads/2017/05/riscv-spec-v2.2.pdf) expects "bne
, , ".
Issue with gcc is passes without the comma as you can experience here

but fails rightfully with clang.

Thanks in advance.
