Chris Lattner f6d6823f09 Let the inliner update the callgraph to reflect the changes it makes, instead 
of doing it ourselves.  This fixes Transforms/Inline/2006-01-14-CallGraphUpdate.ll

 2006-01-14 20:09:18 +00:00
Chris Lattner 0841fb1d4c Teach the inliner to update the CallGraph itself, and have it add edges to 
llvm.stacksave/restore when it inserts calls to them.

 2006-01-14 20:07:50 +00:00
Chris Lattner 7eb2947546 New testcase for a regression last night: the -inline pass wasn't updating

 2006-01-13 20:19:44 +00:00
Chris Lattner c66b223b28 Simplify this a tiny bit by using the new IntrinsicInst functionality. 
llvm-svn: 25292
 2006-01-13 20:11:04 +00:00
Chris Lattner 0de6020d6a Simplify the implementations of classof using the new IntrinsicInst classof. 
llvm-svn: 25291
 2006-01-13 20:00:51 +00:00
Evan Cheng dba84bbc1e LHS = X86ISD::CMOVcc LHS, RHS means LHS = RHS if cc. So the operands must be 
flipped around.

llvm-svn: 25290
 2006-01-13 19:51:46 +00:00
Chris Lattner d5bb9df4d8 Add some functionality to the IntrinsicInst class and some comments 
llvm-svn: 25289
 2006-01-13 19:49:02 +00:00
Chris Lattner 45406c0c53 Permit inlining functions that contain dynamic allocations now that 
InlineFunction handles this case safely.  This implements
Transforms/Inline/dynamic_alloca_test.ll.

llvm-svn: 25288
 2006-01-13 19:35:43 +00:00
Chris Lattner accc5bfe92 New testcase that functions with dynamic allocas can be inlined, and are 
inlined correctly.

llvm-svn: 25287
 2006-01-13 19:35:05 +00:00
Chris Lattner 2be0607a8d If inlining a call to a function that contains dynamic allocas, wrap the 
resultant code with llvm.stacksave/llvm.stackrestore intrinsics.

llvm-svn: 25286
 2006-01-13 19:34:14 +00:00
Chris Lattner e24f79a032 Use ClonedCodeInfo to avoid another walk over the inlined code, this this 
time in common C cases.

llvm-svn: 25285
 2006-01-13 19:18:11 +00:00
Chris Lattner 19e6a08d78 Use the ClonedCodeInfo object to avoid scans of the inlined code when 
it doesn't contain any calls.  This is a fairly common case for C++ code,
so it will probably speed up the inliner marginally in these cases.

llvm-svn: 25284
 2006-01-13 19:15:15 +00:00
Chris Lattner 908d79556d Refactor a bunch of invoke handling stuff out into a new function 
"HandleInlinedInvoke".  No functionality change.
