llvm-svn: 28746
 2006-06-10 04:16:23 +00:00
Reid Spencer 82ebabafde Provide a simpler interface for getting a ConstantArray from a character 
string. Instead of specifying the length, just specify whether the user
wants a terminating null or not. The default is "true" to retain the same
behavior as previously provided by this function.

llvm-svn: 28562
 2006-05-30 18:15:07 +00:00
Reid Spencer 6f61453ff8 Adjust the interface to ConstantArray::get. The previous 
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.

llvm-svn: 23655
 2005-10-07 05:23:36 +00:00
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.

llvm-svn: 23628
 2005-10-04 21:35:50 +00:00
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.

llvm-svn: 23627
 2005-10-04 18:47:09 +00:00
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.

 2005-10-04 18:13:04 +00:00
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.

llvm-svn: 23624
 2005-10-04 17:48:46 +00:00
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.

 2005-10-04 16:52:46 +00:00
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 0144fadc17 minor microoptimizations 
llvm-svn: 23612
 2005-10-03 21:56:24 +00:00
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.

Chris Lattner 9fba3da879 Add a new ConstantAggregateZero class, to fix PR239. This makes zero 
initializers for constant structs and arrays take constant space, instead of

benchmarks.

make the map search be faster anyway.

 2004-01-14 17:06:38 +00:00
Chris Lattner 5a945e3616 Rename ConstantHandling.* -> ConstantFolding.* 
Move a bunch of (now) private stuff from ConstantFolding.h into
ConstantFolding.cpp.

This _finally_ gets us to a place where we have a sane constant folder.  The
rules are:

1. LLVM clients now use ConstantExpr::get* methods to fold constants.  If they
   cannot be folded, a constantexpr is created, so these methods always return
   valid Constant*'s.
2. The implementation of ConstantExpr::get* uses the functions exposed by
   ConstantFolding.h to try to fold constants.  If they cannot be folded,
   they should return a null pointer.
3. The implementation of ConstantFolding can do whatever it wants, and only
   has one client (Constants.cpp)

This cuts down on the wierd dependencies, and eliminates the two interfaces.
The old constanthandling interface was especially bad for clients to use
because almost none of them took the failure condition into consideration,
thus leading to obscure problems.
