Chris Lattner e0536857aa Testcase for PR204 
llvm-svn: 10769
 2004-01-12 05:01:48 +00:00
Chris Lattner 950b713d22 Add support for %llvmgcc

Chris Lattner 49f74522ec * Implement minor performance optimization for the getelementptr case 
* Implement SCCP of load instructions, implementing Transforms/SCCP/loadtest.ll
  This allows us to fold expressions like "foo"[2], even if the pointer is only
  a conditional constant.

Chris Lattner 2ca9b10b6a Test to make sure we can SCCP load instructions

Chris Lattner 7e8af38637 Do not hack on volatile loads. I'm not sure what the point of a volatile load 
from constant memory is, but lets not take chances.

Chris Lattner 05fe6847a8 Implement SCCP/phitest.ll 
llvm-svn: 10763
 2004-01-12 03:57:30 +00:00
Chris Lattner 4d1bb94c3e New testcase, allow folding of binary operators that use PHI nodes, as long 
as the result of the binary operator is always constant.  This does not require
the PHI itself to be constant though.

Chris Lattner fafa2ff2d6 Implement Transforms/ScalarRepl/phinodepromote.ll, which is an important 
case that the C/C++ front-end generates.

Chris Lattner aacf2a5833 Implement: Assembler/2004-01-11-getelementptrfolding.llx 
llvm-svn: 10759
 2004-01-11 23:56:33 +00:00
Chris Lattner fcd7ccd425 This isn't really an assembler test. This tests to make sure the 
ConstantExpr::getGetElementPtr method folds two getelementptr instructions
when possible.

Alkis Evlogimenos 52a714b45b Make LiveVariables::HandlePhysRegUse and 
LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

Also update the TwoAddressInstructionPass to not use this interface.

Chris Lattner 65f901e23b Check in two changes: 
The first change (which is disabled) compactifies all of the function constant
pools into the global constant pool, in an attempt to reduce the amount of
duplication and overhead.  Unfortunately, as the comment indicates, this is
not yet a win, so it is disabled.

The second change sorts the typeid's so that those types that can be used
by instructions in the program appear earlier in the table than those that
cannot (such as structures and arrays).  This causes the instructions to
be able to use the dense encoding more often, saving about 5K on 254.gap.
This is only a .65% savings though, unfortunately. :(

Chris Lattner 3bcecb92f3 Update obsolete comments 
Fix iterator invalidation problems which was causing -mstrip to miss some
entries, and read free'd memory.  This shrinks the symbol table of 254.gap
from 333 to 284 bytes!  :)

llvm-svn: 10751
 2004-01-10 21:36:49 +00:00
Chris Lattner a2bfab849f Do not bother to emit a BytecodeBlock for an empty symbol table. This commonly 
occurs when the symbol table for a module has been stripped, making all of the
function local symbols go away.

This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously
has 841 functions), which isn't a ton, but helps and was easy.

Chris Lattner a4ee66f3ea Finegrainify namespacification. 
This should get hunked over to the Sparc backend, along with
MachineCodeForInstruction and a bunch of files in include/llvm/Codegen,
but those battles will have to wait for a later time.

Chris Lattner 3d874aebc2 Move InstrSelection into lib/Target/Sparc, as it's sparc specific. This 
makes the incestuous #include'ing of sparc internal headers much less
disturbing.  :)
