  "message": "[X86][APX] Fix issue of push2/pop2 instr with stack clash protection (#145303)\n\nWhen -stack-clash-protection option is specified and APX push2pop2 is\nenabled, there will be two calls to emitSPUpdate function which emits\ntwo STACKALLOC_W_PROBING pseudo instructions. The pseudo instruction for\npush2 padding is silently ignored which leads to the stack misaligned to\n16 bytes and GP exception in runtime. Fixed by directly emitting \"push\n%rax\" instruction for push2 padding, instead of calling emitSPUpdate.\nThere was a similar issue on https://reviews.llvm.org/D150033.",
