RISC-V: Fix vector cfi notes for stack-clash protection
The stack-clash code is generating wrong cfi directives in
riscv_v_adjust_scalable_frame because REG_CFA_DEF_CFA has a different
encoding than REG_FRAME_RELATED_EXPR, this patch fixes the offset sign
in prologue and starts using REG_CFA_DEF_CFA in the epilogue.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_v_adjust_scalable_frame): Add
epilogue code for stack-clash and fix prologue cfi note.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/stack-check-cfa-3.c: Fix the expected output.
