e92e4a4342 Token chain results are not always the first or last result. Consider copyfromreg nodes, where they are the middle result (the flag result is last)

f718ef50ad 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

llvm.stacksave/restore when it inserts calls to them.

67a0c03bb4 Permit inlining functions that contain dynamic allocations now that 
InlineFunction handles this case safely.  This implements
Transforms/Inline/dynamic_alloca_test.ll.

inlined correctly.

423aeb28d5 If inlining a call to a function that contains dynamic allocas, wrap the

672f2df6d0 Use ClonedCodeInfo to avoid another walk over the inlined code, this this 
time in common C cases.

 2006-01-13 19:18:11 +00:00
Chris Lattner
6f96396bae 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.

32ff638ae5 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.
