Evan Cheng 4d17671997 No need recognize load from a fixed argument slot as re-materializable. LiveIntervalAnalysis already handles it as a special case.

Evan Cheng e70afb021b Recognize loads of arguments as re-materializable first. Therefore if isReallyTriviallyReMaterializable() returns true it doesn't confuse it as a "normal" re-materializable instruction.

Ted Kremenek f948d2a75f Change encoding of TokenKind in IdentifierTable to be of type "unsigned" 
instead of TokenKind because of signedness issues with MSVC and enums.

Ted Kremenek 652d18e37c Patch from Argiris Kirtzidis: 
The patch fixes some debug assertions that the msvcrt throws:

1)
-    if (isprint(value) && value < 256) {
+    if (value < 256 && isprint(value)) {

isprint() does an assertion check of its own for value < 256; check value before calling it to prevent it.


2)
-    Stmt->Names.push_back(std::string(&data[0], data.size()));
+    if (data.size() == 0)
+      Stmt->Names.push_back(std::string());
+    else
+      Stmt->Names.push_back(std::string(&data[0], data.size()));

If data.size() == 0 then data[0] throws "out of range" assertion.

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.

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.

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.
