the X86 asmparser to produce ranges in the one case that was annoying me, for example:
test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
^~~~~~~
It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use
ranges where appropriate if someone is interested.

is substantially different than a(b|c)d. Form the latter regex instead.
This found a few problems in the testsuite, which serves as its test.

an annoyance of mine when working on tests: if the input .ll file
is broken, opt outputs an error and generates an empty file. FileCheck
then emits its "ooh I couldn't find the first CHECK line, scanning
from ..." which obfuscates the actual problem.

A CHECK-NOT pattern without a following CHECK pattern simply checks that the
pattern doesn't match before the end of the input file.
You can even have only CHECK-NOT patterns to check that strings appear nowhere
in the input file.

good nearby fuzzy match. Frequently the input is nearly correct, and just
showing the user the a nearby sensible match is enough to diagnose the problem.
- The "fuzzyness" is pretty simple and arbitrary, but worked on my three test
cases. If you encounter problems, or places you think FileCheck should have
guessed but didn't, please add test cases to PR5239.
For example, previously FileCheck would report this:
--
t.cpp:21:55: error: expected string not found in input
// CHECK: define void @_Z2f25f2_s1([[i64_i64_ty]] %a0)
^
<stdin>:19:30: note: scanning from here
define void @_Z2f15f1_s1(%1) nounwind {
^
<stdin>:19:30: note: with variable "i64_i64_ty" equal to "%0"
--
and now it also reports this:
--
<stdin>:27:1: note: possible intended match here
define void @_Z2f25f2_s1(%0) nounwind {
^
--
which makes it clear that the CHECK just has an extra ' %a0' in it, without
having to check the input.
