Chris Lattner 33fd702590 Update getelementptr instruction description 
llvm-svn: 12654
 2004-04-05 01:30:49 +00:00
Chris Lattner 69193f93b6 Support getelementptr instructions which use uint's to index into structure 
types and can have arbitrary 32- and 64-bit integer types indexing into
sequential types.

Chris Lattner fd9fbe187d Support getelementptr instructions which use uint's to index into structure 
types and can have arbitrary 32- and 64-bit integer types indexing into
sequential types.

Auto-upgrade .ll files that use ubytes to index into structures to use uint's.

 2004-04-05 01:30:04 +00:00
Chris Lattner 15701e84d1 Implement support for a new LLVM 1.3 bytecode format, which uses uint's 
to index into structure types and allows arbitrary 32- and 64-bit integer
types to index into sequential types.

Chris Lattner dfcf8e34cf In the perhaps not-to-distant future, we might support gep instructions that 
have non-long indices for sequential types.  In order to avoid trying to figure
out how the v9 backend works, we'll just hack it in the preselection pass.

 2004-04-04 17:30:06 +00:00
Chris Lattner bc8ba73cf1 Remove a bunch of cruft that was used to be backwards compatible with the last 
prerelease format for LLVM bytecode files.  Now we only are compatible with
LLVM 1.0+.

Eliminating call-frame pseudo instrs and frame indices are still stubs.

llvm-svn: 12622
 2004-04-02 20:26:04 +00:00
Chris Lattner 2c416ae11f Tweak testcase to work with new indvars pass 
llvm-svn: 12621
 2004-04-02 20:25:26 +00:00
Chris Lattner e61b67d7d5 Rewrite the indvars pass to use the ScalarEvolution analysis. 
This also implements some new features for the indvars pass, including
linear function test replacement, exit value substitution, and it works with
a much more general class of induction variables and loops.

Chris Lattner 9f0db32625 Implement Transforms/SimplifyCFG/return-merge.ll 
This actually causes us to turn code like:

  return C ? A : B;

into a select instruction.

Alkis Evlogimenos d64e904e27 Clean up code a bit. 
llvm-svn: 12615
 2004-04-02 18:11:32 +00:00
Brian Gaeke 2845936a34 Only strip symbols if emitting bytecode to the assembly file. 
Move lowerselect pass to come after preselection.  Move machine
code construction and stack slots pass to come right before instruction
selection. This is to help fix perlbmk.

Update comments.

Make the sequence of passes in addPassesToJITCompile look more like
the sequence of passes in addPassesToEmitAssembly, including support
for -print-machineinstrs.

llvm-svn: 12614

Chris Lattner bcf2623cab minor formatting change 
llvm-svn: 12606
 2004-04-02 06:32:45 +00:00
Chris Lattner a413b08580 Fix two pretty serious bugs: 
1. Each time the loop extractor extracted a loop, we would leak a module.
  2. When we extracted a loop, we didn't add the new function to the list of
     miscompiled functions.  Thus if the bug was in a loop nest and we
     extracted it, we could actually *LOSE THE BUG*, which is very bad.

With these patches, bugpoint has successfully found a bug for me in a function
with several nested loops, and cut it down to just one of them. :) :)

llvm-svn: 12605
 2004-04-02 06:32:17 +00:00
Chris Lattner af67dac7f4 Fix a fairly nasty bug that prevented bugpoint from working quite right when 
hacking on programs with two functions that have the same name.
