Fix typo in last commit on expansion of unaligned loads.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75903 91177308-0d34-0410-b5e6-96231b3b80d8

Expand unaligned 32 bit loads from an address which is a constant
offset from a 32 bit aligned base as follows:

  ldw low, base[offset >> 2]
  ldw high, base[(offset >> 2) + 1]
  shr low_shifted, low, (offset & 0x3) * 8
  shl high_shifted, high, 32 - (offset & 0x3) * 8
  or result, low_shifted, high_shifted

Expand 32 bit loads / stores with 16 bit alignment into two 16 bit
loads / stores.

Custom lower unaligned 32 bit stores and loads into libcalls. This is
a big code size win since before they were expanding to upto 16
instructions.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75901 91177308-0d34-0410-b5e6-96231b3b80d8

Let callers decide the sub-register index on the def operand of rematerialized instructions.
Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.

use SUBREG_TO_REG instead of INSERT_SUBREG, this way the code

Thanks to Dan for pointing this out.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75888 91177308-0d34-0410-b5e6-96231b3b80d8

Kill off <TARGET>MachineModule variables, and <TARGETASMPRINTER>ForceLink
variables.
 - Module initialization functions supplanted the need for these.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75886 91177308-0d34-0410-b5e6-96231b3b80d8

formatted_raw_ostream both is-a raw_ostream and has-a raw_ostream. This
means that two separate raw_ostreams are doing buffering before data is
sent to the underlying stream. Besides the inefficiency of redundant
buffering, the second level of buffering doesn't recieve flush()
requests.

Fix this by having formatted_raw_ostream set the underlying raw_ostream
to be unbuffered. This eliminates inefficiency due to redundant buffering,
and it makes the flush() disconnect harmless.

This fixes PR4559.

Skip special LLVM prefix '1' while emitting linknage name.
This prefix is used by LLVM to inform the asm printer to not emit usual global symbol prefix before the symbol name.

Now that we have contexts on types, convert some more internals to use contexts.

We don't need to use llvm_report_error, this interface can deal with errors

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75864 91177308-0d34-0410-b5e6-96231b3b80d8

Verify that there is no kill flag on tied operands on two-address instructions.
This extra check is not trigged when runnning "make check" on top-of-tree.

Change error message to better match llvm_unreachable() grammar.

Don't call llvm_unreachable() when writing error messages to a file, but keep going.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75860 91177308-0d34-0410-b5e6-96231b3b80d8

Lift addAssemblyEmitter into LLVMTargetMachine.
 - No functionality change.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75859 91177308-0d34-0410-b5e6-96231b3b80d8

Fix this comment to mention outs() rather than cout.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75858 91177308-0d34-0410-b5e6-96231b3b80d8

Change raw_ostream so that it doesn't call llvm_report_error
immediately on every output error. Instead, add a flag to
raw_ostream, and set the flag whenever an error is detected.

The flag can be queried and cleared from the public API. This
gives applications more flexibility to handling errors in
application-specific ways.

If the flag is not cleared when the raw_ostream is destructed,
llvm_report_error is called from the destructor. This ensures
that errors are not implicitly silenced, and provides
convenient default behavior for tools like llc and opt.
Clients wishing to avoid llvm_report_error calls from
raw_ostream should check for errors and clear the error flag.

Fix bug in RegScavenger::scavengeRegister().

Reserved registers are not candidates for scavenging, and they were removed
from the candidate list like this:

CreateRegClassMask(RC, Candidates);
Candidates ^= ReservedRegs;

However, when there are reserved registers outside RC, this causes invalid
bits to be set in Candidates.

To simplify the upcoming context-on-type change, switch all command line tools to using the default global context for now.

This will let us to hardwire stuff to the global context in the short term while the API is sorted out.

Fix a thinko in a comment that Duncan spotted.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75803 91177308-0d34-0410-b5e6-96231b3b80d8

Add a Force option to raw_fd_ostream to specify whether opening
an existing file is considered an error. Convert several tools
to use raw_fd_ostream instead of std::ostream, and to use this
new option instead of doing a manual check.

Revert 75762, 75763, 75766..75769, 75772..75775, 75778, 75780, 75782 to repair broken LLVM-GCC build.
Will revert 75770 in the llvm-gcc trunk.

The static function TypeToFloatSemantics is now
unused - remove it.

Fix pattern for LD16S_3r, add basic tests to check load / store instructions
are being properly selected.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75795 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75794 91177308-0d34-0410-b5e6-96231b3b80d8

Use 0664 instead of 0644 for the default open mode. This is
consistent with common std::ostream implmentations, and it gives
the user the option of using the umask group write bit.

Remove the v3i32 and v3f32 value types: they are not
native for any supported targets.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75785 91177308-0d34-0410-b5e6-96231b3b80d8

Replace large swaths of copy-n-paste code with obvious helper function...
 - Which was already present in the module!

 - I skipped this xform for Alpha, since it runs an extra pass during assembly
   emission, but not when emitting assembly via the DumpAsm flag.

 - No functionality change.

from.

   TargetMachine subclasses' constructor calls.

Migrate llc and the JIT to using the TargetRegistry for lookups.
 - They still use the TargetMachineRegistry to populate the contents of the
   -march option (via the listener interface). We can't just populate it in the
   option parser because we can't expect the TargetRegistry to be populated yet
   (we no longer rely on static constructors).

 - There are a couple ways to finish killing off TargetMachineRegistry, but I
   haven't figured out the cleanest one yet...

Allow multiple registrations of the same target.
 - This doesn't necessarily seem like a good idea, but the JIT unittest
   currently relies on it.

Reimplement TargetMachineRegistry in terms of TargetRegistry.
 - This is a temporary hack to aid in incremental refactoring, for now we
   allocate a new TargetMachineRegistryEntry on every getClosest... call.

 - No intended functionality change, other than the leaked memory.

Register Target's TargetMachine and AsmPrinter in the new registry.

   cleaned up in time.
