2010-11-14FileCheck: Eliminate DOSish \r from input file.NAKAMURA Takumi1-0/+5
It can pass two tests below on Win32. - Clang :: CodeGenCXX/dyncast.cpp - LLVM :: CodeGen/ARM/globals.ll llvm-svn: 119023
2010-10-15Teach FileCheck to handle trailing CHECK-NOT patterns.Jakob Stoklund Olesen1-9/+22
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. llvm-svn: 116592
2010-08-20Trailing whitespace.Mikhail Glushenkov1-80/+80

2010-04-05stringref-ize the MemoryBuffer::get apis. This requiresChris Lattner1-4/+2
a co-committed clang patch. llvm-svn: 100485

"scanning from here" one. llvm-svn: 98971
2010-01-30FileCheck: When looking for "possible matches", only compare against the prefixDaniel Dunbar1-1/+4
line. Turns out edit_distance can be slow if the string we are scanning for happens to be quite large. llvm-svn: 94860

2010-01-29Fix the position of the caret in the FileCheck error message.Dan Gohman1-1/+4
Before: test/CodeGen/X86/lsr-reuse.ll:52:34: error: expected string not found in input ; CHECK: movsd -2048(%rsi), %xmm0 ^ After: test/CodeGen/X86/lsr-reuse.ll:52:10: error: expected string not found in input ; CHECK: movsd -2048(%rsi), %xmm0 ^ llvm-svn: 94846
2010-01-29FileCheck: Switch "possible match" calculation to use StringRef::edit_distance.Daniel Dunbar1-6/+1
- Thanks Doug, who is obviously less lazy than me! llvm-svn: 94795
2009-11-29Fix FileCheck crash when fuzzy scanning starting at the end of the file.Daniel Dunbar1-1/+1
llvm-svn: 90065
2009-11-22FileCheck, PR5239: Try to find the intended match on failures, but looking for aDaniel Dunbar1-4/+60
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. llvm-svn: 89631
2009-11-22FileCheck: When a string using variable references fails to match, printDaniel Dunbar1-4/+50
additional information about the current definitions of the variables used in the string. llvm-svn: 89628
2009-11-22Allow '_' in FileCheck variable names, it is nice to have at least oneDaniel Dunbar1-2/+3
separate character. - Chris, OK? llvm-svn: 89626
2009-09-27implement and document support for filecheck variables. ThisChris Lattner1-43/+172
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. llvm-svn: 82891
2009-09-26remove support for "NoSub" from regex. It seems like a minor optimizationChris Lattner1-1/+1
and makes the API more annoying. Add a Regex::getNumMatches() method. llvm-svn: 82877
2009-09-25reject attempts to use ()'s in patterns, these are reserved for filecheck.Chris Lattner1-3/+15
llvm-svn: 82780
2009-09-25reimplement the regex matching strategy by building a singleChris Lattner1-88/+51
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". llvm-svn: 82779
2009-09-25special case Patterns that are a single fixed string. This is a microscopicChris Lattner1-0/+16
perf win and is needed for future changes. llvm-svn: 82777

llvm-svn: 82754
2009-09-24add and document regex support for FileCheck. You can now do stuff like:Chris Lattner1-11/+116
; CHECK: movl {{%e[a-z][xi]}}, %eax or whatever. llvm-svn: 82717
2009-09-24Use CanonicalizeInputFile to canonicalize the entire buffer containing theChris Lattner1-57/+40
CHECK strings, instead of canonicalizing the patterns directly. This allows Pattern to just contain a StringRef instead of std::string. llvm-svn: 82713
2009-09-24change 'not' matching to use Pattern, move pattern parsing logic intoChris Lattner1-32/+51
the Pattern class. llvm-svn: 82712

trying to wrap strstr which is just too inconvenient. Make it use a StringRef to avoid ".c_str()" calls. llvm-svn: 79120
2009-08-15Instead of using an std::pair, use a custom struct.Chris Lattner1-12/+21
