Reid Spencer 7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

llvm-svn: 16137
 2004-09-01 22:55:40 +00:00
Reid Spencer 74c3dc6927 Add the LLVMsystem.a library as it is now used for operating system 
independence of the tool.

llvm-svn: 16092
 2004-08-29 19:29:38 +00:00
Reid Spencer e3263ecaf0 The functions in Signal.h are now in the llvm::sys namespace - adjust

 2004-08-29 19:28:55 +00:00
Chris Lattner 7ba1be09b3 Remove redundant SCCP pass 
Add new DSE pass.  Add a temporary option to disable it in case we need it
This is going in after the July 22 nightly tester run, so we'll wait until the 23rd to see it
:)

 2004-05-27 05:41:36 +00:00
Chris Lattner bf9ba24155 Move loop optimization passes up, add loop unroller 
llvm-svn: 13030
 2004-04-18 05:21:01 +00:00
Chris Lattner 024385ba5f Turn on argument promotion in gccas. This can give us substantially better 
code in cases where the file has lots of static functions or anon namespaces.

llvm-svn: 12361
 2004-03-13 21:38:35 +00:00
Chris Lattner 0f39359dd2 Add a new pass 
llvm-svn: 11838
 2004-02-25 21:35:02 +00:00
Chris Lattner 69e896bdcf Make sure to print a stack trace whenever an error signal is delivered to 
the tool.

llvm-svn: 11633
 2004-02-19 20:32:39 +00:00
Chris Lattner eddfe437c7 Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas. 
This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

llvm-svn: 11053
 2004-02-01 07:24:53 +00:00
Chris Lattner 298d2f090f Make sure to verify the result before writing out the bytecode file. Not doing 
so can cause obscure errors downstream.

llvm-svn: 10840
 2004-01-14 03:39:46 +00:00
Chris Lattner cf1755a6f3 Add a -disable-opt flag to gccas, so that we can use -Wa,-disable-opt just 
like -Wl,-disable-opt

Chris Lattner db8a179838 Revert the previous patch since it causes lots of miscompilations. :( :( 
llvm-svn: 10172
 2003-11-22 19:07:47 +00:00
Chris Lattner 52b4fb3fde Reorder passes a bit. In particular, it makes sense to run globaldce IMMEDIATELY after funcresolve. Also, run the mem2reg pass _early_ so that IPCP and DAE actually do stuff. 
Run instcombine and simplify cfg after this to cleanup the intraprocedural messes we create.

llvm-svn: 10134
 2003-11-21 21:44:35 +00:00
Chris Lattner 093cc6dc92 As the comments indicate, this is a temporary, repulsive, hack

Chris Lattner 3334c884bc Give this file a proper header 
llvm-svn: 9141
 2003-10-15 21:49:57 +00:00
Chris Lattner 4973805acd The levelraise pass is a broken old piece of crufty code that should be 
left on the side of the road without a second thought.

It is preventing forward progress, so for now, we will disable it by default.

Chris Lattner 387d76a983 * Remove the -stopraise option, which is no longer needed now that we have 
the -debug-pass=Arguments option
* Run instcombining BEFORE mem2reg so that getelementptr X, long 0's are
  cleaned up.  This is also important because scalar replacement of aggr.
  will want instcombine to run before it goes as well.

 2002-09-22 18:50:22 +00:00
Vikram S. Adve 9c485d2165 gcc3.1.1 seems much more selective about what it loads from archives, and 
does not link in many passes that are loaded by gcc2.95.3.  So use object
files instead of archives in many more cases.

llvm-svn: 3803
 2002-09-18 02:20:58 +00:00
Chris Lattner c70222dc15 * No longer need to run die after instcombine

  on constant booleans, etc) after correlated exprs pass.

Chris Lattner c065ad850c Make sure that there is no case where a signal can occur leaving a partially
