Brian Gaeke 92aefe564a Here are the notes from our Reoptimizer meetings. 
llvm-svn: 6923
 2003-06-26 20:37:42 +00:00
Chris Lattner 5a42f1b49e Modify script to support checkins on branches

Brian Gaeke 4ab222142f Number constants from constant pool as CPIf_i where f is the function index 
and i is the constant pool index.

Chris Lattner d104cdb0ba Add a testcase to ensure that ctor/dtor attributes work in C

llvm-svn: 6918
 2003-06-26 05:41:18 +00:00
Chris Lattner fd5d323ea9 When internalizing global ctor/dtor list, also mark it constant. This is gross, but 
until DSA is working all of the time and is totally reliable, we do this.

llvm-svn: 6917
 2003-06-26 05:30:40 +00:00
Chris Lattner c8a619313a Run the simplify CFG pass after instcombine which has the effect of deleting 
ALL of the global ctor/dtor stuff if it is not used!

llvm-svn: 6916

 2003-06-26 05:05:51 +00:00
Chris Lattner e4b7d467f8 Move the instcombine pass before globaldce, so that if globals are made dead by instcombine, that they can be deleted. 
llvm-svn: 6910

Chris Lattner 0fe5e45ee9 Don't register the destructors if the list is empty

 2003-06-25 22:00:39 +00:00
Brian Gaeke 25e766aca5 First draft of X86 LLC backend. This should be OK for small programs like 
Shootout, but it has some issues with bigger programs. Work in progress.

llvm-svn: 6907
 2003-06-25 18:01:07 +00:00

 2003-06-25 14:31:06 +00:00
Joel Stanley fbb9ab4913 - Fixed name mangling conditions to handle 'linkonce' linkage type. In 
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

Chris Lattner 0192b72fde Run dead arg elimination, and tell it that it's ok to hack up non-internal functions 
llvm-svn: 6896
 2003-06-25 04:13:36 +00:00

 2003-06-25 04:12:49 +00:00
Brian Gaeke 7610971759 It seems likely that floats would need a cast too, because they are 
ordinarily promoted to doubles.

Chris Lattner 834105502d Do not mark ALL terminators live if any instruciton in the block is live. We only 
want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.

Chris Lattner 55d4bda861 Implement new transforms:

Brian Gaeke 04bdfe624c Fix 2003-06-23-PromotedExprs.llx -- if we are adding two bytes we better 
explicitly cast the result to be a byte, or C will gleefully promote it
to int.

llvm-svn: 6869
