Use %link not %llvmgxx (which includes -c) to do the link.
The test still fails because an expected symbol is not
present, and I don't see why it should be.

instead.

This fixes 7 testcases that were not properly running before.

Also, use > %t instead of -o %t for output in one test since that also works

This fixes 6 testcases.

Fix some llvm-gcc warnings in testcases, mostly by adding includes or adding
declarations. These are the fixes that I was pretty confident about, there are
still a lot of other llvm-gcc warnings of which I'm not sure if they can be
safely ignored or fixed, without breaking the test case.

This fixes 11 testcases.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52176 91177308-0d34-0410-b5e6-96231b3b80d8

For all RUN lines starting with "not", redirect stderr to /dev/null so tests
don't fail when (expected) error output is produced. This fixes 17 tests.

While I was there, I also made all RUN lines of the form "not llvm-as..." a bit
more consistent, they now all redirect stderr and stdout to /dev/null and use
input redirect to read their input.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52174 91177308-0d34-0410-b5e6-96231b3b80d8

Suppress the (stderr) output of -aa-eval, this fixes 5 tests.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52173 91177308-0d34-0410-b5e6-96231b3b80d8

Change llvm.exp so it no longer ignores some errors when executing dejagnu
tests. This breaks 80 tests in the tree.

The interesting part here is that this no longer ignores syntax errors
in RUN command lines. Some tests have not been working all the time because of
this.

The tricky part is that it now also views any stderr output as an error. This
can be suppressed in tcl 8.5, but let's not add this dependency. Instead, all
testcases should be changed to redirect stderr if they expect stderr output.
This holds in particular for lines like:
  ; RUN: not llvm-as < %s
where an error is expected (but I think I can solve this by modifying the not
script). Also, compilations resulting in warnings will now also fail (so
the warnings should be fixed, disabled or redirected...).

I'll continue with fixing the testcases that are broken now.

Remove comparison methods for MVT.  The main cause

Testcase for PR2418

Handle assembler identifiers specially in CBE. This fixes PR2418.

Tighten up the abstraction slightly.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52045 91177308-0d34-0410-b5e6-96231b3b80d8

Wrap MVT::ValueType in a struct to get type safety
and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).

As Chris suggested, handle the situation if ShAmt larger than BitWidth,
otherwise, opt might crash.

Turn stdout into binary mode during bitcode emission.
This is necessary on windows targets, since stdout is in text mode there.
