Torok Edwin fbcd2c76d5 Fix TimeValue::now() on Unix.
TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.

Rafael Espindola 2c5792a6bd Catch more cases of a pointer being marked garbage twice. This helps when
debugging some leaks (PR5770 in particular).

Duncan Sands 9ed7b16bf3 Introduce and use convenience methods for getting pointer types
where the element is of a basic builtin type.  For example, to get
an i8* use getInt8PtrTy.

Chris Lattner 37d8015dc1 remove support for "NoSub" from regex. It seems like a minor optimization
and makes the API more annoying.  Add a Regex::getNumMatches() method.

Jeffrey Yasskin 14a5cc54e5 Fix a compile failure introduced by r82675 on MinGW which doesn't have
setenv().  This patch just disables the test rather than getting putenv() to
work.  Thanks to Sandeep Patel for reporting the problem.

2009-09-25 21:07:20 +00:00
Chris Lattner f08d2db928 add and document regex support for FileCheck. You can now do stuff like:
; CHECK: movl {{%e[a-z][xi]}}, %eax

or whatever.

Jeffrey Yasskin a75d6bf3a8 Roll back r82348, which introduced an infinite loop in ParseCStringVector() that
a trivial unittest would have caught.  This revision also adds the trivial
unittest.

Daniel Dunbar 316b4a0206 Drop the raw_ostream required buffer size to 1.
- As best I can tell, we have eliminated all the code which used to require a
   larger buffer size.

Jeffrey Yasskin ccbeaf5f94 Make TypeBuilder's result depend on the LLVMContext it's passed.
TypeBuilder was using a local static variable to cache its result. This made it
ignore changes in its LLVMContext argument and always return a type constructed
from the argument to the first call.

Daniel Dunbar da30ecdcdd Simplify, now that gtest supports raw_ostream directly.

Nick Lewycky d592399beb Now that googletest can print ConstantRange, use EXPECT_EQ when testing for
equality. Prefer EXPECT_EQ(foo, Full) over EXPECT_TRUE(foo.isFullSet()) because
the former will print out the contents of the constant range that failed.

llvm-svn: 81094
2009-09-05 18:27:40 +00:00
Jeffrey Yasskin b797fdc365 Teach googletest to use raw_ostream instead of just std::ostream.
This can break when there are implicit conversions from types raw_ostream
understands but std::ostream doesn't, but it increases the number of cases that
Just Work.

Torok Edwin e14d4cdb5f Add regular expression matching support, based on OpenBSD regexec()/regcomp()
implementation.

Chris Lattner 0ffe0e096d split raw_os_ostream out to its own header and implementation file. This
means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

Daniel Dunbar 47a309c5ca Fix off-by-one in llvm::Format::print.
- This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)

Chris Lattner dbbdc79267 convert all the constant range EXPECT_EQ tests to use EXPECT_TRUE since
ConstantRange doesn't have an std::ostream inserter anymore.

Benjamin Kramer 9ace8b5763 Fix unit test on FreeBSD. We need to make sure there is enough space to save the pointer even if the memory returned from malloc was already aligned.

Jeffrey Yasskin 6bf87df579 To catch bugs like the one fixed in
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the
ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That
way, if unregistering a mapping fails to actually unregister it, we'll get an
assert. Running the jit nightly tests didn't uncover any actual instances of
the problem.

This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed
that too.

Owen Anderson 5a1acd9912 Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are
metadata related, which I'm waiting on to avoid conflicting with Devang.

Reid Kleckner 921673225c Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

Reid Kleckner 5bd6105d65 Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

Nick Lewycky 567daf3ce8 Fix ConstantRange::unionWith. Also make it work a little hard in some cases to
return the smallest union of two ranges instead of just any range that happens
to contain the union.

Nick Lewycky 0d13903563 Replace intersectWith with maximalIntersectWith. The latter guarantees that
all values belonging to the intersection will belong to the resulting range.
The former was inconsistent about that point (either way is fine, just pick
one.) This is part of PR4545.

Owen Anderson 53a52215b5 Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.
