FileCheck, PR5239: Try to find the intended match on failures, but looking for a
...
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.

reimplement the regex matching strategy by building a single
...
regex and matching it instead of trying to match chunks at a time.
Matching chunks at a time broke with check lines like
CHECK: foo {{.*}}bar
because the .* would eat the entire rest of the line and bar would
never match.
Now we just escape the fixed strings for the user, so that something
like:
CHECK: a() {{.*}}???
is matched as:
CHECK: {{a\(\) .*\?\?\?}}
transparently "under the covers".
