Evan Cheng b6d981bddd Same isPhysRegAvailable bug as local register allocator. 
llvm-svn: 47500
 2008-02-22 20:31:32 +00:00
Evan Cheng 52c15b3e6d Really really bad local register allocator bug. On X86, it was never using ESI, EDI, and EBP because of a bug in RALocal::isPhysRegAvailable(). For example, when 
it checks if ESI is available, it then looks at registers aliases to ESI. SIL is marked -2 (not allocatable) but isPhysRegAvailable() incorrectly assumes it is in use and returns false for ESI.

Ted Kremenek c77f34daad Modified clang driver option -dump-live-variables to (optionally) use the 
--analyze-function option to analyze specific functions.

Evan Cheng 94ba37f8e3 Allow re-materialization of pic load (controlled by -remat-pic-load for now). 
llvm-svn: 47476
 2008-02-22 09:25:47 +00:00
Evan Cheng c373911461 Enable re-materialization of instructions which have virtual register operands if 
the definition of the operand also reaches its uses.

Chris Lattner ab8bfc28c8 copy mmx values from/to memory with GPRs on x86-32 
instead of with mmx registers.  This horribleness is apparently
done by gcc to avoid having to insert emms in places that really 
should have it.  This is the second half of rdar://5741668.

 2008-02-22 02:49:49 +00:00
Chris Lattner 997b3a65ca Start using GPR's to copy around mmx value instead of mmx regs. 
GCC apparently does this, and code depends on not having to do
emms when this happens.  This is x86-64 only so far, second half
should handle x86-32.

Dan Gohman f3057a939d Fix a regression in 403.gcc and 186.crafty introduced in 47383. To test 
that a value is >= 32, check that all of the high bits are zero, not
just one or more.

Ted Kremenek cb507025d4 Added "assumption" logic for lval::FuncVal and lval::GotoLabel, and simplified 
assumption logic for lval::DeclVal.

Eli Friedman 5d8fa828f1 A few minor updates, removing implemented stuff and adding a couple of 
new things.

Chris Lattner 3422b673d1 Make the clobber analysis a bit more smart: we only are careful about 
early clobbers if the clobber list contains a *register* not some thing
like {memory}, {dirflag} etc.

llvm-svn: 47457
 2008-02-21 20:54:31 +00:00
Ted Kremenek 9f1ed12bc4 Added transfer function support for dispatching to functions we don't know 
about.  The default logic is to invalidate the values of all values
passed-by-reference.

llvm-svn: 47456

Nate Begeman b16d53ea31 add a test case 
llvm-svn: 47455
 2008-02-21 19:44:16 +00:00
Chris Lattner bdd4c8b04d Treat clobber operands like early clobbers: if we have 
any, we force sdisel to do all regalloc for an asm.  This
leads to gross but correct codegen.

This fixes the rest of PR2078.

an error to cast it to LVal.
