Craig Topper 1d578e8835 Fix a bunch of SSE/AVX patterns to use proper memop types. In particular, not using integer loads other than v2i64/v4i64 since the others are all promoted.

Evan Cheng 7f8e563a69 Add bundle aware API for querying instruction properties and switch the code 
generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

Jakob Stoklund Olesen 2f0400b780 Eliminate delta argument from AdjustBBOffsetsAfter. 
The block offset can be computed from the previous block. That is more
robust than keeping track of a delta.

Eliminate one redundant AdjustBBOffsetsAfter call.

Jakob Stoklund Olesen b0d91abec0 Add MachineOperand IsInternalRead flag. 
This flag is used when bundling machine instructions.  It indicates
whether the operand reads a value defined inside or outside its bundle.

for better diagnostics and disambiguation of instructions.

Jim Grosbach ba39592cee Extend AsmMatcher token literal matching to allow aliasing. 
For example, ARM allows:
    vmov.u32 s4,   -> vmov.i32, 
'u32' is a more specific designator for the 32-bit integer type specifier
and is legal for any instruction which accepts 'i32' as a datatype suffix.

We want to say,
    def : TokenAlias<".u32", ".i32">;

This works by marking the match class of 'From' as a subclass of the
match class of 'To'.

Jakob Stoklund Olesen 33fe130e12 Use conservative size estimate for tBR_JTr. 
This pseudo-instruction contains a .align directive in its expansion, so
the total size may vary by 2 bytes.

It is too difficult to accurately keep track of this alignment
directive, just use the worst-case size instead.

 2011-12-06 21:55:39 +00:00
Jakob Stoklund Olesen 2fa7448f31 Remove alignment from deserted constant islands. 
ARMConstantIslandPass may sometimes leave empty constant islands behind
(it really shouldn't). Remove the alignment from the empty islands so
the size calculations are still correct.

This should fix the many Thumb1 assembler errors in the nightly test
suite.

The reduced test case for this problem is way too big. That is to be
expected for ARMConstantIslandPass bugs.
