Reid Spencer 7e80b0b31e For PR950:
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

Reid Spencer e0fc4dfc22 For PR950:
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

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.

Reid Spencer 8f8124edaa Fix PR409:

don't get accepted by LLVM accidentally. Adjust the supporting test cases
as well.

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.

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.

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.

llvm-svn: 23623
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 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.
