tablegen leaks like a sieve.  This includes some valgrindArgs refactoring.

Bob Wilson 614d1fdfc3 Fix a very bad typo. Since the register number was off by one, the ARM
load/store optimizer would incorrectly think that registers D26 and D28

The assembler was not convinced.

Dan Gohman 1a2abe5580 Clear the SCEVExpander's insertion point after making deletions,
so that the SCEVExpander doesn't retain a dangling pointer as its
insert position. The dangling pointer in this case wasn't ever used
to insert new instructions, but it was causing trouble with
SCEVExpander's code for automatically advancing its insert position
past debug intrinsics.

This fixes use-after-free errors that valgrind noticed in
test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
test/Transforms/IndVarSimplify/exit_value_tests.ll.

64-bit form for 'CRC32 r64, r/m8'.  Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.

Bob Wilson bc5af98f42 Stop trying to merge identical jump tables. This had been inadvertently
disabled for several months (since svn r88806) and no one noticed.  My fix
for pr6543 yesterday reenabled it, but broke the ARM port's code for using
TBB/TBH.  Rather than adding a target hook to disable merging for Thumb2 only,
I'm just taking this out.  It is not common to have identical jump tables,
the code we used to merge them was O(N^2), and it only helps code size, not
performance.

Daniel Dunbar 1a81ad3559 MC/Mach-O/x86_64: Add relocation support.
- This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
 - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
 - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)

Chris Lattner 83facb0812 Now that tblgen can handle matching implicit defs of instructions
to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking
two inputs (which have to be the same type) and *returning an i32*.
This is how the SDNodes get made in the graph, but we weren't able
to model it this way due to deficiencies in the pattern language.

Now we can change things like this:

 def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP,
-                  [(X86cmp RFP80:$lhs, RFP80:$rhs),
-                   (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i)
+                  [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>;

and fix terrible crimes like this:

-def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)),
+def : Pat<(X86cmp GR8:$src1, 0),
           (TEST8rr GR8:$src1, GR8:$src1)>;

This relies on matching the result of TEST8rr (which is EFLAGS, which is
an implicit def) to the result of X86cmp, an i32.

Bob Wilson 3c7cde466e Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() to
always create a new jump table.  The intention was to avoid merging jump
tables in SelectionDAGBuilder, and to wait for the branch folding pass to
merge tables.  Unfortunately, the same getJumpTableIndex() method is also
used to merge tables in branch folding, so as a result of this change
branch tables are never merged.  Worse, the branch folding code is expecting
getJumpTableIndex to always return the index of an existing table, but with
this change, it never does so.  In at least some cases, e.g., pr6543, this
creates references to non-existent tables.

I've fixed the problem by adding a new createJumpTableIndex function, which
will always create a new table, and I've changed getJumpTableIndex to only
look at existing tables.

Jeffrey Yasskin fa22878d9d Avoid a problem in libc_freeres() seen on a linux-i686 buildbot when running
under valgrind:

==19577== Invalid free() / delete / delete[]
==19577==    at 0x4C9C866: free (vg_replace_malloc.c:325)
==19577==    by 0x5121104: ??? (in /lib/libc-2.10.2.so)

==19577==  Address 0xffffffff is not stack'd, malloc'd or (recently) free'd

Apparently this happens under certain versions of glibc, so valgrind provides
the --run-libc-freeres=no option to avoid calling freeres().  This may increase
the number of "still reachable" blocks valgrind reports, but we don't care
about those, while this error breaks the buildbots.

There are upstream bugs about this at
http://sourceware.org/bugzilla/show_bug.cgi?id=10610 and
http://bugs.kde.org/show_bug.cgi?id=167483, but they don't look likely to be

Daniel Dunbar 6544baff6f MC/Darwin: Add a new target hook for whether the target uses "reliable" symbol differences, basically whether the assembler should attempt to understand atoms when using scattered symbols.
Also, avoid some virtual call overhead.

Jakob Stoklund Olesen 8575110ae1 Revert "Change coalescer complexity from N^2 to N logN by changing one letter."
This reverts commit 98776. It broke the llvm-gcc boot strap.

Evan Cheng 68333f5c6e X86 address mode matching code MatchAddressRecursively does some aggressive hack which require doing a RAUW. It may end up deleting some SDNode up stream. It should avoid referencing deleted nodes.

There is a better way coming up.

Jakob Stoklund Olesen 6589f7152e Change coalescer complexity from N^2 to N logN by changing one letter.
Remove ugly hack that aborted the coalescer before using N^2 time.

This affects functions with very complicated live intervals for physical
registers, i.e. functions with thousands of function calls.

Johnny Chen 0910b5afac Fixed a bug in the IT mask printing where T means the cond bit in the mask
matches that of Firstcond[0] and E means otherwise.  The Firstcond[0] is also
tagged in the Mask to facilitate Asm printing.  The disassembler also depends
on this arrangement.  This is similar to what's described in A2.5.2 ITSTATE.

Ran:

utils/lit/lit.py test/CodeGen/ARM test/CodeGen/Thumb test/CodeGen/Thumb2

successfully.

Johnny Chen 8609782366 Refines 98745 so that it only contains the patch related to the output of the
addressing modes to omit the '+' from the assembler syntax #+/-<imm> or +/-<Rm>.

This patch removes the impl of printT2AddrModeImm8s4OffsetOperand() from
ARMAsmPrinter.cpp.  It is used by disassembler as of now.
