# RUN: not llvm-mc -triple powerpc-unknown-unknown < %s 2>&1 | FileCheck %s
# This tests the mnemonic spell checker.
# First check what happens when an instruction is omitted:
%r1, %r2, %r3
# CHECK: error: unexpected token at start of statement
# CHECK-NEXT: %r1, %r2, %r3
# CHECK-NEXT: ^
# We don't want to see a suggestion here; the edit distance is too large to
# give sensible suggestions:
aaaaaaaaaaaaaaa %r1, %r2, %r3
# CHECK: error: invalid instruction
# CHECK-NEXT: aaaaaaaaaaaaaaa %r1, %r2, %r3
# CHECK-NEXT: ^
# Check that we get one suggestion: 'vmaxfpg' is 1 edit away, i.e. an deletion.
vmaxfpg %r1, %r2
# CHECK: error: invalid instruction, did you mean: vmaxfp?
# CHECK-NEXT: vmaxfpg %r1, %r2
# CHECK-NEXT: ^
# Check edit distance 1 and 2, just insertions:
xsnmsubad %r1, %r2
# CHECK: error: invalid instruction, did you mean: xsmsubadp, xsnmsubadp?
# CHECK-NEXT: xsnmsubad %r1, %r2
# CHECK-NEXT: ^
# Check an instruction that is 2 edits away, and also has a lot of candidates:
adXd %r1, %r2, %r3
# CHECK: error: invalid instruction, did you mean: add, addc, adde, addi, addo, fadd?
# CHECK-NEXT: adXd %r1, %r2, %r3
# CHECK-NEXT: ^
