Ted Kremenek d94669675b Revert "Add -exact-match option to FileCheck to allow clients to do exact matches without using regular expressions."
Turns out I did not need it after all.  If we find a use for it in the future, we
can resurrect it.

Chris Lattner a3a0681083 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance
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.

Chris Lattner e53c95f180 fix PR9629 - We were lowering regexes like a{{b|c}}d into ab|cd, which
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.

Chris Lattner b692bed732 emit a specific error when the input file is empty. This fixes
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.

Jakob Stoklund Olesen eba55822d7 Teach FileCheck to handle trailing CHECK-NOT patterns.
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.

Daniel Dunbar fd29d88605 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.

Chris Lattner 8879e06d0a implement and document support for filecheck variables. This
allows matching and remembering a string and then matching and
verifying that the string occurs later in the file.

Change X86/xor.ll to use this in some cases where the test was
checking for an arbitrary register allocation decision.

2009-09-25 17:29:36 +00:00
Chris Lattner b16ab0c40a 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".
