9e69654461 Infer mayload 
llvm-svn: 45819
 2008-01-10 04:44:48 +00:00

1ca2068227 realize that instructions who match intrinsics that read memory read memory. 
Also, instructions with any nodes that are SDNPMayLoad also read memory.

07fde9bde1 add a mayLoad property for machine instructions, a correlary to mayStore. 
This is currently not set by anything.

03ad885039 rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

e99a6caee4 Rename all the M_* flags to be namespace qualified enums, and switch 
all clients over to using predicates instead of these flags directly.
These are now private values which are only to be used to statically
initialize the tables.

that they are accurate, thx.

fd548c96cc Move M_* flags down in the file. Move SchedClass up in the 
TargetInstrDescriptor class and shrink to 16-bits, saving a 
word in TargetInstrDescriptor.  Add some comments.

just unconditionally use the def name of the instruction.

a348f55ec6 Change the 'isStore' inferrer to look for 'SDNPMayStore' 
instead of "ISD::STORE".  This allows us to mark target-specific dag
nodes as storing (such as ppc byteswap stores).  This allows us to remove
more explicit isStore flags from the .td files.

Finally, add a warning for when a .td file contains an explicit 
isStore and tblgen is able to infer it.

e457fd1e9b remove some old hacky code that tried to infer whether a store 
occured in a pattern, but failed miserably.  The new code works for
any instruction that has a store in its pattern, including all the 
x86 mem op mem instructions.

The only target-independent code that uses this is branch folding,
so this won't change anything in practice.

7980bba549 now that computing CodegenDAGPatterns doesn't implicitly print stuff 
out, DAGISelEmitter can compute it in its ctor, which simplifies some code.

Now we can use CodegenDAGPatterns in other parts of tblgen that want access
to dag pattern info, woo!

edf0788758 Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

38ef3a8ec7 Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

f4127dd48e Rewrite the tblgen parser in a recursive descent style, eliminating the bison parser. 
This makes the parser much easier to understand, eliminates a ton of global variables,
and gives tblgen nice caret diagnostics.  It is also faster, but tblgen probably doesn't
care about performance.

There are a couple of FIXMEs which I will take care of next.

07b57d2626 This change does a couple of things. First it gets the Visual Studio builds working. 
I added the lexing files to the VStudio projects and removed the .l files from the 
VStudio projects.  There was a problem with use of strtoll in TGLexer.cpp and Chris
suggested switching to strtol, so that's included here.

Additionally, this checkin adds minimal x64 builds to the VStudio builds.  Build issues
related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc
are worked around, but not ultimately solved.  Binaries used to be stored in

...\win32\{Debug|Release}

but are now kept in

...\win32\bin\{win32|x64}\{Debug|Release}

intermediate files will continue to be stored in the individual project directories under 
win32.  

Some names will likely change in the future to reflect that the vstudio projects
are no longer 32-bit only, but I wanted to get things up and running today so kept away
from bigger restructuring.
