Chris Lattner 7eb2947546 New testcase for a regression last night: the -inline pass wasn't updating 
callgraph to include new edges do to inserted llvm.stacksave/llvm.stackrestore
calls.

Evan Cheng dba84bbc1e LHS = X86ISD::CMOVcc LHS, RHS means LHS = RHS if cc. So the operands must be 
flipped around.

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.

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.

Chris Lattner edad1288fd Allow the code cloning interfaces to capture some important info about the 
code being cloned if the client wants.

llvm-svn: 25281
 2006-01-13 18:39:17 +00:00
Chris Lattner 257492c0ab Fix a bug I noticed by inspection: if the first instruction in the inlined 
function was not an alloca, we wouldn't check the entry block for any allocas,
leading to increased stack space in some cases.  In practice, allocas are almost
always at the top of the block, so this was never noticed.

Chris Lattner ed9b3e1c0a If a target specified a stack pointer with setStackPointerRegisterToSaveRestore, 
lower STACKSAVE/STACKRESTORE into a copy from/to that register.

llvm-svn: 25276
 2006-01-13 17:48:44 +00:00
