Chris Lattner 89046ca244 Implement a new method
llvm-svn: 16927
2004-10-12 04:20:25 +00:00
Chris Lattner 13128ab8fb Allow creation of GEP constantexprs with a vector of value* operands as
well as a vector of constant*'s.  It turns out that this is more efficient
and all of the clients want to do that, so we should cater to them.

Chris Lattner b2b7f90caf If we are trying to create a ConstantExpr cast that is really a GEP to the
first element of an array, return a GEP instead of a cast.  This allows us
to transparently fold this:

int* getelementptr (int* cast ([100 x int]* %Gbody to int*), int 40)

into this:

int* getelementptr ([100 x int]* %Gbody, int 0, int 40)

Chris Lattner 251093ca5d Unfortunately the fix for the previous bug introduced the previous
exponential behavior (bork!).  This patch processes stuff with an
explicit SCC finder, allowing the algorithm to be more clear,
efficient, and also (as a bonus) correct!  This gets us back to taking
0.6s to disassemble my horrible .bc file that previously took something
> 30 mins.

Chris Lattner cef3c06027 Fix a bug in my previous change. Unfortunately this reverts most of the
speedup, but has the advantage of not breaking a bunch of programs!

Chris Lattner 43e03c9cdf Change Type::isAbstract to have better comments, a more correct name
(PromoteAbstractToConcrete), and to use a set to avoid recomputation.
In particular, this set eliminates the potentially exponential cases
from this little recursive algorithm.

On a particularly nasty testcase, llvm-dis on the .bc file went from 34
minutes (which is when I killed it, it still hadn't finished) to 0.57s.
Remember kids, exponential algorithms are bad.

Chris Lattner c9e79d005b Don't use DominatorSet::dominates for intra-block instruction dom checks.
This method is linear time in the size of the basic block, which is very
bad for large basic blocks.  On the Assembler/2004-09-29-VerifierIsReallySlow.llx
testcase, the verifier changes from taking 50s to 0.23s with this patch.

Chris Lattner 4f2cf030e8 'Pass' should now not be derived from by clients. Instead, they should derive
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

Chris Lattner 79e523de04 'Pass' should now not be derived from by clients. Instead, they should derive

Also, fix some undefined behavior, expecting | on booleans to evaluate
left-to-right.

Reid Spencer f27c4cde06 Okay, the list of link-time passes wasn't such a hot idea. Its prone to
error. We'll strategize on this when we have multiple front ends to deal
with. For now llvm-ld just runs a standard set of transforms.

Reid Spencer 1b34fde1cc Implement support for dependent libraries. The "source" module's dependent
libraries list is merged into the "destination" module's list. Also, if the
source module is one of the dependent libraries, it is removed from the

Chris Lattner 8439f382b6 Fix a nasty bug that Nate ran into. In particular, instead of emitting a 2+MB
error message, print out:

llvm-link: error linking in 'g.2.rbc': Global Variable Collision on
' %struct.D_Reduction* %d_reduction_10_gram' - External linkage globals have
different initializers

That's a bit more concise, huh?

Reid Spencer b0ac8c48a6 Fix PR422.
Ouch! Changes in the lazy initialization code caused each incorporated
function to reprocess the entire function on every lookup of a value's
slot number. This caused a horrible slowdown in all functions. This
fix made llvm-dis go from "longer than I care to wait" (minutes) on a large
test case to 0.53 seconds.
