Keep track of which stage produced a live range, and bypass earlier stages when revisiting.

This effectively disables the 'turbo' functionality of the greedy register
allocator where all new live ranges created by splitting would be reconsidered
as if they were originals.

There are two reasons for doing this, 1. It guarantees that the algorithm
terminates. Early versions were prone to infinite looping in certain corner
cases. 2. It is a 2x speedup. We can skip a lot of unnecessary interference
checks that won't lead to good splitting anyway.

The problem is that region splitting only gets one shot, so it should probably
be changed to target multiple physical registers at once.

Local live range splitting is still 'turbo' enabled. It only accounts for a
small fraction of compile time, so it is probably not necessary to do anything
about that.

{aliasee}. From there, it's a simple matter to emit the {alias}, with the

situation.

handle AsmOperands at the moment. It also doesn't know what to do when two
{alias}es match the same {aliasee}. (Currently, it just ignores those two cases

13 years agoAdd some options for building LLVM in different environments:
David Greene [Fri, 25 Feb 2011 20:51:27 +0000 (20:51 +0000)]
Add some options for building LLVM in different environments:

--force-configure to force running configure before building.

--extra-llvm-config-flags
--extra-llvm-gcc-config-flags
--extra-gcc-config-flags

Pass additional argument to the various configure invocations.

This also eliminates a default build flavor because explicitly
specifying builds could result in build flavors being run repeatedly.

Finally, turn off fortran builds for the moment because install
appears to be broken.

Yes, there are other types than i8* and GEPs on them can produce an add+multiply.
We don't consider that cheap enough to be speculatively executed.
