this clone is supposed to be used for *ALL* of the functions in the SCC.
This fixes the memory explosion problem the TD pass was having, reducing the

This obviously also speeds up the TD pass *a lot*.

Remove a bunch of cruft and dead code for handling the case when types were
...
defined in function constant pools. The assembler grammar has long
disallowed functions from having constant pools, so all of this stuff is
dead.
This makes it an immediate error for functions to refer to nonexisting
types, fixing Regression/Verifier/2005-03-21-UndefinedTypeReference.ll.
Before, references to non-existing types in functions would only be
detected when the subsequent function was parsed, due to the call to
"ResolveTypes". "ResolveTypes" has not resolved any types for a long time,
instead it emitted an error message if no resolved types are left. Since
the only caller of this method is in the module code, just inline it.

Change the way that the TD pass inlines graphs. Instead of inlining each
...
graph into all of the functions it calls when we visit a graph, change it so
that the graph visitor inlines all of the callers of a graph into the current
graph when it visits it.
While we're at it, inline global information from the GG instead of from each
of the callers. The GG contains a superset of the info that the callers do
anyway, and this way we only need to do it one time (not one for each caller).
This speeds up the TD pass substantially on several programs, and there is
still room for improvement. For example, the TD pass used to take 147s
on perlbmk, it now takes 36s. On povray, we went from about 5s to 1.97s.
134.perl is down from ~1s for Loc+BU+TD to .6s.
The TD pass needs a lot of improvement though, which will occur with later
patches.

Create an equivalence class of global variables that DSA will never be able
...
to tell apart anyway, and only track the leader for of these equivalence
classes in our graphs.
This dramatically reduces the number of GlobalValue*'s that appear in scalar
maps, which A) reduces memory usage, by eliminating many many scalarmap entries
and B) reduces time for operations that need to execute an operation for each
global in the scalar map.
As an example, this reduces the memory used to analyze 176.gcc from 1GB to
511MB, which (while it's still way too much) is better because it doesn't hit
swap anymore. On eon, this shrinks the local graphs from 14MB to 6.8MB,
shrinks the bu+td graphs of povray from 50M to 40M, shrinks the TD graphs of
130.li from 8.8M to 3.6M, etc.
This change also speeds up DSA on large programs where this makes a big
difference. For example, 130.li goes from 1.17s -> 0.56s, 134.perl goes
from 2.14 -> 0.93s, povray goes from 15.63s->7.99s (!!!).
This also apparently either fixes the problem that caused DSA to crash on
perlbmk and gcc, or it hides it, because DSA now works on these. These
both take entirely too much time in the TD pass (147s for perl, 538s for
gcc, vs 7.67/5.9s in the bu pass for either one), but this is a known
problem that I'll deal with later.

Allow the live interval analysis pass to be a bit more aggressive about
...
numbering values in live ranges for physical registers.
The alpha backend currently generates code that looks like this:
vreg = preg
...
preg = vreg
use preg
...
preg = vreg
use preg
etc. Because vreg contains the value of preg coming in, each of the
copies back into preg contain that initial value as well.
In the case of the Alpha, this allows this testcase:
void "foo"(int %blah) {
store int 5, int *%MyVar
store int 12, int* %MyVar2
ret void
}
to compile to:
foo:
ldgp $29, 0($27)
ldiq $0,5
stl $0,MyVar
ldiq $0,12
stl $0,MyVar2
ret $31,($26),1
instead of:
foo:
ldgp $29, 0($27)
bis $29,$29,$0
ldiq $1,5
bis $0,$0,$29
stl $1,MyVar
ldiq $1,12
bis $0,$0,$29
stl $1,MyVar2
ret $31,($26),1
This does not seem to have any noticable effect on X86 code.
This fixes PR535.

This fixes PR531, a crash when running the CBE on a bytecode file.
...
The problem is that Function::renameLocalSymbols is iterating through
the symbol table planes, occasionally calling setName to rename a value
(which used to do a symbol table remove/insert pair).
The problem is that if there is only a single value in a particular type
plane that the remove will nuke the symbol table plane, and the insert
will create and insert a new one. This hoses Function::renameLocalSymbols
because it has an iterator to the old plane, under the (very reasonable)
assumption that simply renaming a value won't cause the type plane to
disappear.
This patch fixes the bug by making the rename operation a single atomic
operation, which has a side effect of making the whole thing faster too. :)

Fix a nasty order of evaluation bug that Gabor Greif ran into. Here's an
...
explanation from IRC:
|sabre| I think it's an order of evaluation thing
|sabre| for me, the RHS of the assignment is evaluated first
|sabre| getTypeDescription checks to see if ConcreteTypeDescription[Ty] contains anything
|sabre| since it doesn't, it computes and returns the value
|sabre| this gets put into the map.
|sabre| For you, the LHS is evaluated first.
|sabre| Map[Ty] (aka ConcreteTypeDescriptions[Ty]) inserts an empty string into the map, returning a reference
|sabre| getTypeDesc then sees the empty string in the map
|sabre| and returns it
|sabre| bork :)

Fixed the following LSR bugs:

* Loop invariant code does not dominate the loop header, but rather
the end of the loop preheader.
* The base for a reduced GEP isn't a constant unless all of its
operands (preceding the induction variable) are constant.
* Allow induction variable elimination for the simple case after all.
Also made changes recommended by Chris for properly deleting
instructions.

Fix a bug in the 'store fpimm, ptr' -> 'store intimm, ptr' handling code.
...
Changing 'op' here caused us to not enter the store into a map, causing
reemission of the code!! In practice, a simple loop like this:
no_exit: ; preds = %no_exit, %entry
%indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=3]
%tmp.4 = getelementptr "complex long double"* %P, uint %indvar, uint 0 ; <double*> [#uses=1]
store double 0.000000e+00, double* %tmp.4
%indvar.next = add uint %indvar, 1 ; <uint> [#uses=2]
%exitcond = seteq uint %indvar.next, %N ; <bool> [#uses=1]
br bool %exitcond, label %return, label %no_exit
was being code gen'd to:
.LBBtest_1: # no_exit
movl %edx, %esi
shll $4, %esi
movl $0, 4(%eax,%esi)
movl $0, (%eax,%esi)
incl %edx
movl $0, (%eax,%esi)
movl $0, 4(%eax,%esi)
cmpl %ecx, %edx
jne .LBBtest_1 # no_exit
Note that we are doing 4 32-bit stores instead of 2. Now we generate:
.LBBtest_1: # no_exit
movl %edx, %esi
incl %esi
shll $4, %edx
movl $0, (%eax,%edx)
movl $0, 4(%eax,%edx)
cmpl %ecx, %esi
movl %esi, %edx
jne .LBBtest_1 # no_exit
This is much happier, though it would be even better if the increment of ESI
was scheduled after the compare :-/

%A = volatile load int** %P
ret void
}
void %test2(int*** %Q) {
%P = load int*** %Q
volatile store int** %P, int*** %Q
ret void
}
instead of emitting:
void test(int **l1_P) {
int *l2_A;
l2_A = (int **((volatile int **)l1_P));
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((volatile int ***)l2_Q) = l1_P;
return;
}
... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):
void test(int **l1_P) {
int *l3_A;
l3_A = *((int * volatile*)l1_P);
return;
}
void test2(int ***l2_Q) {

If we have an indirect call site that calls N functions, inline the N functions
...
into a temporary graph, remember it for later, then inline the tmp graph into
the call site.
In the case where there are other call sites to the same set of functions, this
permits us to just inline the temporary graph instead of all of the callees.
This turns N*M inlining situations into an N+M inlining situation.

* Make some methods more const correct.
...
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
This makes many operations on these lists much more natural, and avoids
*exteremely* expensive copying of DSCallSites (e.g. moving nodes around
between lists, erasing a node from not the end of the vector, etc).
With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc. I expect that it would help TD even more, but I don't
have data for it.
This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

This file was schizophrenic when it came to representing sizes. In some

cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts. In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.
This patch unifies all of the sizes to use size_t instead.
