Chris Lattner 7d2b049404 change TLS_ADDR lowering to lower to a real mem operand, instead of matching as 
a global with that gets printed with the :mem modifier.  All operands to lea's 
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this.  There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).

This also makes the use of EBX explicit in the operand list in the 32-bit, 
instead of implicit in the instruction.

Chris Lattner 40f560d433 remove dead code, the main codepath never has to deal 
with MBB's.

llvm-svn: 73830
 2009-06-20 19:34:47 +00:00
Chris Lattner 9c2119616f eliminate the "call" operand modifier from the asm descriptions, modeling 
it as a pcrel immediate instead.  This gets pc-rel weirdness out of the
main printoperand codepath.

Duncan Sands 2ae473f739 Clarify that if the alignment is zero then an alignment 
compatible with the type will be used (at least the ABI
alignment).

Argyrios Kyrtzidis a3aeb5a8f1 Introduce Decl::getSourceRange() which, like Stmt::getSourceRange(), represents the range that the declaration covers. 
Add initial support for NamespaceDecl, VarDecl, and FunctionDecl:
-NamespaceDecl range is from name to '}'
-VarDecl is from name to possible init expression
-FunctionDecl is from name to last parameter name or to end of its function body.

Chris Lattner 4682015e61 Start implementing translation of MachineInstr to MCInst. Next 
step is to make tblgen generate something more appropriate for MCInst,
and generate calls to operand translation routines where needed.
This includes a bunch of #if 0 code which will slowly be refactored into
something sensible.

Dan Gohman dcdc4daa5d Tweak this test to be a little less unusual.

Dan Gohman 450f4e0fa9 Generalize isLoopGuardedByCond's checking to consider two 
SCEVUnknowns with identical Instructions to be equal. This allows
it to analze cases such as the attached testcase, where the front-end
has cloned the loop controlling expression. Along with r73805, this
lets IndVarSimplify eliminate all the sign-extend casts in the
loop in the attached testcase.
