Nate Begeman 848622f87f Add support alignment of allocation instructions.
Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

Chris Lattner 3b793c6521 refactor a bit of code.
When moving constant entries in 'Map' if the entry is the representative
constant for the abstractypemap, make sure to update it as well.  This
fixes the bcreader failures from last night on several C++ apps.

Chris Lattner dff59118c6 Minor speedup to avoid array searches given a Use*. This speeds up bc reading
of the python test from 1:00 to 54s.

Chris Lattner 7a1450dbc6 Change the signature of replaceUsesOfWithOnConstant. The bool was always
true dynamically.  Finally, pass the Use* that replaceAllUsesWith has into
the method for future use.

Chris Lattner 935aa922e3 For large constants (e.g. arrays and structs with many elements) just
creating the keys and doing comparisons to index into 'Map' takes a lot
of time.  For these large constants, keep an inverse map so that 'remove'
and move operations are much faster.

This speeds up a release build of the bc reader on Eric's nasty python
bytecode file from 1:39 to 1:00s.

Chris Lattner 5bbf60a5b6 minor cleanup/fastpath for the bcreader. This speeds up the bcreader
from 1:41 -> 1:39 on the large python .bc file in a release build.

Chris Lattner 8760ec73d8 implement the struct version of the array speedup, speeding up the
testcase a bit more from 1:48 -> 1.40.

llvm-svn: 23619
2005-10-04 01:17:50 +00:00
Chris Lattner b64419ac40 Change ConstantArray::replaceUsesOfWithOnConstant to attempt to update
constant arrays in place instead of reallocating them and replaceAllUsesOf'ing
the result.  This speeds up a release build of the bcreader from:

136.987u 120.866s 4:24.38
to
49.790u 49.890s 1:40.14

... a 2.6x speedup parsing a large python bc file.

Chris Lattner e7e139e8e8 Split SimpleConstantVal up into its components, so each Constant subclass getsa different enum value. This allows 'classof' for these to be really simple,not needing to call getType() anymore.
This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.

2005-08-05 01:03:27 +00:00
Chris Lattner 6f58350daf Now that hasConstantValue is more careful w.r.t. returning values that only
dominate the PHI node, this code can go away.  This also makes passes more
aggressive, e.g. implementing Transforms/CondProp/phisimplify2.ll

2005-08-05 01:02:04 +00:00
Chris Lattner bcd8d2c6e5 Use the bool argument to hasConstantValue to decide whether the client is
prepared to deal with return values that do not dominate the PHI.  If we
cannot prove that the result dominates the PHI node, do not return it if
the client can't cope.

population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.
