Turns out that Thumb2 ADR doesn't need special printing like LDR does.  Fix other test failures I caused.

Print out immediate offset versions of PC-relative load/store instructions as [pc, #123] rather than simply #123.

Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

This makes sure that the unwind destination of an invoke is a landing pad.

llvm-svn: 140280

This inserts a cleanup landingpad instruction and a resume to mimic the old
unwind instruction.

Otherwise we'll spend a ridiculous amount of time pretty printing debug output and then discarding it.

These do not need to be conditional on the presence of CommentStream, as they have a fallback path now.

MipsArchVersion needs to be initialized to Mips32.

Vector SetCC result types need to be type-legalized.
This code worked before because scalar result types are known to be legal.

Insert a sanity check on the combining of x86 truncing-store nodes. This comes to replace the problematic check that was removed in r139995.

llvm-svn: 140246

  assert(!"error message");

To:

  assert(0 && "error message");

which is more consistant across the code base.

Check if architecture & ABI combination is valid.

This is still a hack until we can teach tblgen to generate the
optional CPSR operand rather than an implicit CPSR def. But the
strangeness is now limited to the selection DAG. ADD/SUB MI's no
longer have implicit CPSR defs, nor do we allow flag setting variants
of these opcodes in machine code. There are several corner cases to
consider, and getting one wrong would previously lead to nasty
miscompilation. It's not the first time I've debugged one, so this
time I added enough verification to ensure it won't happen again.

In the disassembler C API, be careful not to confuse the comment streamer that the disassembler outputs annotations on with the streamer that the InstPrinter will print them on.

Make sure IPSCCP never marks a tracked call as overdefined in SCCPSolver::ResolvedUndefsIn.  If we do, we can end up in a situation where a function is resolved to return a constant, but the caller is marked overdefined, which confuses the code later.

subvector inserts and extracts. Initial patch by Rackover, Zvi with
some tweak done by me.

It happens (for example) when you want to have a dependency on the .so
with the specific version, like liblzma.so.1.0.0 or
libcrypto.so.0.9.8.

Some passes require breaking critical edges before they're called. Don't
segfault because of that.

Place the check for an exit landing pad where it will be run on both code paths through the if-then-else.

llvm-svn: 140195

The landing pad must accompany the invoke when it's extracted. However, if it
does, then the loop isn't properly extracted. I.e., the resulting extraction has
a loop in it. The extracted function is then extracted, etc. resulting in an
infinite loop.

This was only needed to locate llvm-gcc's installation directory when clang
falls back to run llvm-gcc for i386 kexts.  As of clang svn r140187, we're
now just searching paths with several different Darwin versions on either
side of the current version, so this is no longer needed.
