fix MCSectionELF to not leak memory, just like I did for MCSymbol.
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

fix a memory leak yjasskin pointed out: MCSymbol is bump pointer
allocated and thus not freed. This is cool except that it contains
and std::string so the string data didn't get freed. In any case
there is no reason to redundantly store the string data in the
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.

eliminate some #if 0 code I added in r96905, type inference
now enforces that input/output named values have hte same type.

Commit by lattner :: r98534 /llvm/trunk/utils/TableGen/ (7 files): (link)

Completely rewrite tblgen's type inference mechanism,
changing the primary datastructure from being a
"std::vector<unsigned char>" to being a new TypeSet class
that actually has (gasp) invariants!

This changes more things than I remember, but one major
innovation here is that it enforces that named input
values agree in type with their output values.

This also eliminates code that transparently assumes (in
some cases) that SDNodeXForm input/output types are the
same, because this is wrong in many case.

This also eliminates a bug which caused a lot of ambiguous
patterns to go undetected, where a register class would
sometimes pick the first possible type, causing an
ambiguous pattern to get arbitrary results.

With all the recent target changes, this causes no
functionality change!

MachineMove ctor doesn't need to to mutate input, add 'const'

do some serious surgery on CellSPU to get it back into a world
where it uses types consistently.

fix a few more ambiguous types.

add some missing types

various cleanups from daniel

Commit by lattner :: r98527 /llvm/trunk/lib/Target/ARM/ARMInstrNEON.td: (link)

fix an ambiguous pattern, contrary to expectations, scalar_to_vector
doesn't have a type constraint on the scalar because we don't have
an 'sAny' type.

Commit by lattner :: r98526 /llvm/trunk/ (2 files in 2 dirs): (link)

remove dead method.

Commit by lattner :: r98525 /llvm/trunk/lib/System/Unix/Program.inc: (link)

don't forget to close a FD on an error condition, found by
cppcheck, PR6617. Patch by Ettl Martin!

Commit by lattner :: r98524 /llvm/trunk/docs/LangRef.html: (link)

tidy up and expound more on how half-float works.

tidy indentation

no really, all 64-bit cpu's have cmov support. This should
fix the rest of the buildbot failures on non-x86 hosts.

Commit by lattner :: r98521 /llvm/trunk/test/CodeGen/X86/ (3 files): (link)

filecheckize a test and mark these wiht a cpu so it passes
on hosts without cmovs.

Commit by lattner :: r98520 /llvm/trunk/lib/Target/X86/X86.td: (link)

all 64-bit cpus have cmov, this should fix CodeGen/X86/cmov.ll
(at least) on non-x86 builders.

fix ShrinkDemandedOps to not leave dead nodes around,
fixing PR6607

Commit by lattner :: r98511 /llvm/trunk/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp: (link)

rewrite ShrinkDemandedOps to be faster and indent less,
no functionality change.

make -view-isel-dags print after the 'ShrinkDemandedOps' pass.
