Chris Lattner 13780ac7db big endian 32-bit systems (e.g. ppc32) want to return the high reg first, not 
the lo-reg first.  This is fallout from my ppc calling conv change yesterday,
it fixes test/ExecutionEngine/2003-05-06-LivenessClobber.llx

 2007-03-06 19:25:02 +00:00
Devang Patel 4a8725cf2f Use schedulePass() instead of assignPassManager() to add new LPPassManager.

is the right length.

llvm-svn: 34965
 2007-03-06 10:02:38 +00:00
Evan Cheng 372c2c69f8 Register scavenger is now capable of scavenging. It spills a register whose use of furthest away to make it available. 
llvm-svn: 34964
 2007-03-06 10:01:25 +00:00
Anton Korobeynikov e7ec3bc7bc Use new SDIselParamAttr enumeration. This removes "magick" constants 
from formal attributes' flags processing.

llvm-svn: 34963
 2007-03-06 08:12:33 +00:00
Chris Lattner 70c3c66e38 temporarily disable this until Reid has a chance to fix it.

Reid Spencer 4e42790c43 1. Make StoreValueToMemory a little more efficient by not requiring caller 
to make a copy of the GenericValue.
2. Fix a copy & paste bug in StoreValueToMemory where 64-bit values were
   truncated to 32

llvm-svn: 34958
 2007-03-06 05:03:16 +00:00
Reid Spencer d7c6174f85 Make StoreValueToMemory a little more efficient by not copying a 
GenericValue to a temporary.

llvm-svn: 34957
 2007-03-06 05:02:28 +00:00
Reid Spencer 1efc4aaf84 Fix some thinko's in the last patch. PtrSize has to be in bits and we 
might need to zext not just trunc the value.

llvm-svn: 34955
 2007-03-06 03:46:41 +00:00
Reid Spencer 10dbc1e896 Fix a bug in IntToPtr. Truncating to 64-bits only works if the integer 
is larger. Adjust so that it truncates to pointer width, only if necessary.

llvm-svn: 34954
 2007-03-06 03:41:50 +00:00
Reid Spencer fe5550b2cf Obtain the exit function before execution just in case the module 
disappears before we get to calling the exit function.

llvm-svn: 34953
 2007-03-06 03:12:55 +00:00
Reid Spencer c764c55745 Simplify code as a result of the change in GenericValue to have a single 
integer field of type APInt instead of different sized integer fields.

llvm-svn: 34952
 2007-03-06 03:11:31 +00:00
Reid Spencer 40015aad5a Radically simplify execution. This patch gets rid of all the special 
handling for integer of various sizes. GenericValue now has just a single
integer field of type APInt. We use its facilities directly in the
execution of all instructions.

llvm-svn: 34951
 2007-03-06 03:09:31 +00:00
Reid Spencer c45e10474a Adjust and simplify external function processing now that GenericValue has 
a single integer field of type APInt.

llvm-svn: 34950
 2007-03-06 03:08:12 +00:00
Reid Spencer 7f68713eb8 APInt's are no longer allocated on the heap because they are direct 
members of GenericValue. Consequently the code to clean them up isn't
needed.

llvm-svn: 34948
 2007-03-06 03:06:48 +00:00
Reid Spencer 2d89fa84bc Remove the insufficient code in Interpreter::create that computed the 
Target DataLayout incorrectly. For now, we'll trust that the module has
got the correct DataLayout. In the future, this needs to be changed to
tell the TargetData to be "current host".

llvm-svn: 34947
 2007-03-06 03:05:57 +00:00
Reid Spencer 87aa65f40e Simplify things significantly because GenericValue now has a single integer 
field, of type APInt, instead of multiple integer fields. Also, get rid of
the special endianness code in StoreValueToMemory and LoadValueToMemory.
ExecutionEngine is always used to execute on the host platform so this is
now unnecessary.

llvm-svn: 34946
 2007-03-06 03:04:04 +00:00
Reid Spencer b5caad1d5c Make GenericeValue into a struct with a union instead of just a union. This 
allows an APInt value to be constructed. Remove all the native integer types
from the union. These are replaced with the single IntVal of type APInt.
