Generally, remove use of fork/exec from bugpoint in favor of the portable
sys::Program::ExecuteAndWait method. This change requires two new options
to bugpoint to tell it that it is running in "child" mode. In this mode,
it reads its input and runs the passes. The result code signals to the
parent instance of bugpoint what happened (success, fail, crash).
This change should make bugpoint usable on Win32 systems.

This patch adds a -post-link-opts option to llvm-ld which allows an arbitrary
program to optimize bytecode after linking. The program is passed two file
names. The first is the input (linked bytecode) the second is where it must
place its output (presumably after optimizing). If the output file is bytecode,
it is used as a substitute for the input. This will allow things like poolalloc
to be written as a separate program instead of a loadable module or built into
LLVM.

This ugly patch works around a GCC bug where it is compiling SelectCode to
...
use too much stack space, overflowing the stack for large functions. Instead
of emitting new SDOperands in each match block, we emit some common ones at
the top of SelectCode then reuse them when possible.
This reduces the stack size of SelectCode from 28K to 21K. Note that GCC
compiles it to 512 bytes :-/
I've filed GCC PR 25505 to track this.

Reserve G1 for frame offset stuff and use it to handle large stack frames.

For example, instead of emitting this:
test:

add %i6, -40016, %o0 ;; imm too large
call caller
nop
restore %g0, %g0, %g0
retl
nop
emit this:
test:
sethi 4194264, %g1
or %g1, 848, %g1
save %o6, %g1, %o6
sethi 4194264, %g1
add %g1, %i6, %g1
add %i1, 944, %o0
call caller
nop
restore %g0, %g0, %g0
retl
nop
which doesn't cause the assembler to barf.

it keeps it from trying to add the same node to the node set

are a lot of patterns to be matched, and it matches an early one, this
will make the script run slightly faster. It's more there because it logically
should be, than anything else, I mean, Python is never going to be fast ;-)

last night, breaking crafty and twolf. Make sure that the newly found

iterations by depending on this behavior instead of having to misuse 'do
another iteration' to get the same effect.

Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows

us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register. This also requires some asm printer work
to satisfy the darwin assembler.
For
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = add <4 x float> %tmp1, %tmp1
store <4 x float> %tmp2, <4 x float> *%a
ret void
}
We now produce:
_foo:
lvx v0, 0, r3
vaddfp v0, v0, v0
stvx v0, 0, r3
blr
Instead of:
_foo:
li r2, 0

This is a script to extract nodes and edges associated with those nodes
...
from a dot file that is the output of DSA. Nodes to extract
are specified by giving the name of the node seen in the graphical
representation, i.e. in the .ps if the node is specified %xyz
asking for just x, xy, or xyz will retain it in the output file.
Because it operates on substrings underspecifying may result
in additional unexpected nodes. Be as specific as possible.
Obviously, however, if you ask for %xyz and there is a
getelementptr of %xyz you will get both nodes. Some manual
editing may still be necessary because of this, but this script
can pare down 10,000 line files to 20 line files, making like easier.

add andn/orn/xorn patterns. This allows us to compile this:
...
long %test(ubyte, short, long %X, long %Y) {
%A = xor long %X, -1
%B = and long %Y, %A
ret long %B
}
to this:
test:
save -96, %sp, %sp
andn %i4, %i2, %i0
andn %i5, %i3, %i1
restore %g0, %g0, %g0
retl
nop
instead of this:
test:
save -96, %sp, %sp
xor %i2, -1, %l0
xor %i3, -1, %l1
and %i4, %l0, %i0
and %i5, %l1, %i1
restore %g0, %g0, %g0
retl
nop
The simpleisel emits: :(
test:
save -96, %sp, %sp
or %g0, -1, %l0
or %g0, -1, %l0
or %g0, -1, %l0
or %g0, -1, %l1
xor %i2, %l0, %l0
xor %i3, %l1, %l1
and %i4, %l0, %i0
and %i5, %l1, %i1
restore %g0, %g0, %g0
retl
nop
