From 1fc65a65fe54635d0e564559ba5a7b8a8a42d4d6 Mon Sep 17 00:00:00 2001
From: dim <dim@FreeBSD.org>
Date: Mon, 11 Oct 2010 17:22:16 +0000
Subject: Remove more unneeded files and directories from contrib/llvm. This
still allows us to build tblgen and clang, and further reduces the footprint
in the tree.

- str lr, [sp, #+52]
- ldr lr, [r1, #+32]

-
-Note ADDri is not a two-address instruction. However, its result %reg1037 is an
-operand of the PHI node in bb76 and its operand %reg1039 is the result of the
-PHI node. We should treat it as a two-address code and make sure the ADDri is
-scheduled after any node that reads %reg1039.

- add r3, r3, #3

- add r2, r2, #2
- ldr r1, [sp, #+4] <==
- add r1, r1, #1

- add r0, r0, #2

-
-LLVM aggressively lift CSE out of loop. Sometimes this can be negative side-
-effects:
-
-R1 = X + 4
-R2 = X + 7
-R3 = X + 15
-
-loop:
-load [i + R1]
-...
-load [i + R2]
-...
-load [i + R3]
-
-Suppose there is high register pressure, R1, R2, R3, can be spilled. We need
-to implement proper re-materialization to handle this:
-
-R1 = X + 4
-R2 = X + 7
-R3 = X + 15
-
-loop:
-R1 = X + 4 @ re-materialized
-load [i + R1]
-...
-R2 = X + 7 @ re-materialized
-load [i + R2]
-...
-R3 = X + 15 @ re-materialized
-load [i + R3]
-
-Furthermore, with re-association, we can enable sharing:
-
-R1 = X + 4
-R2 = X + 7
-R3 = X + 15
-
-loop:
-T = i + X
-load [T + 4]
-...
-load [T + 7]
-...
-load [T + 15]
-//===---------------------------------------------------------------------===//
-
-It's not always a good idea to choose rematerialization over spilling. If all
-the load / store instructions would be folded then spilling is cheaper because
-it won't require new live intervals / registers. See 2003-05-31-LongShifts for
-an example.
-
-//===---------------------------------------------------------------------===//
-
-With a copying garbage collector, derived pointers must not be retained across
-collector safe points; the collector could move the objects and invalidate the
-derived pointer. This is bad enough in the first place, but safe points can
-crop up unpredictably. Consider:
-
- %array = load { i32, [0 x %obj] }** %array_addr
- %nth_el = getelementptr { i32, [0 x %obj] }* %array, i32 0, i32 %n
- %old = load %obj** %nth_el
- %z = div i64 %x, %y
- store %obj* %new, %obj** %nth_el
-
-If the i64 division is lowered to a libcall, then a safe point will (must)
-appear for the call site. If a collection occurs, %array and %nth_el no longer
-point into the correct object.
-
-The fix for this is to copy address calculations so that dependent pointers
-are never live across safe point boundaries. But the loads cannot be copied
-like this if there was an intervening store, so may be hard to get right.
-
-Only a concurrent mutator can trigger a collection at the libcall safe point.
-So single-threaded programs do not have this requirement, even with a copying
-collector. Still, LLVM optimizations would probably undo a front-end's careful
-work.
-
-//===---------------------------------------------------------------------===//
-
-The ocaml frametable structure supports liveness information. It would be good
-to support it.
-
-//===---------------------------------------------------------------------===//
-
-The FIXME in ComputeCommonTailLength in BranchFolding.cpp needs to be
-revisited. The check is there to work around a misuse of directives in inline
-assembly.
-
-//===---------------------------------------------------------------------===//
-
-It would be good to detect collector/target compatibility instead of silently
-doing the wrong thing.
-
-//===---------------------------------------------------------------------===//
-
-It would be really nice to be able to write patterns in .td files for copies,
-which would eliminate a bunch of explicit predicates on them (e.g. no side
-effects). Once this is in place, it would be even better to have tblgen
-synthesize the various copy insertion/inspection methods in TargetInstrInfo.
-
-//===---------------------------------------------------------------------===//
-
-Stack coloring improvments:
-
-1. Do proper LiveStackAnalysis on all stack objects including those which are
- not spill slots.
-2. Reorder objects to fill in gaps between objects.
- e.g. 4, 1, <gap>, 4, 1, 1, 1, <gap>, 4 => 4, 1, 1, 1, 1, 4, 4
-
-//===---------------------------------------------------------------------===//
-
-The scheduler should be able to sort nearby instructions by their address. For
-example, in an expanded memset sequence it's not uncommon to see code like this:
-
- movl $0, 4(%rdi)
- movl $0, 8(%rdi)
- movl $0, 12(%rdi)
- movl $0, 0(%rdi)
-
-Each of the stores is independent, and the scheduler is currently making an
-arbitrary decision about the order.
-
-//===---------------------------------------------------------------------===//
-
-Another opportunitiy in this code is that the $0 could be moved to a register:
-
- movl $0, 4(%rdi)
- movl $0, 8(%rdi)
- movl $0, 12(%rdi)
- movl $0, 0(%rdi)
-
-This would save substantial code size, especially for longer sequences like
-this. It would be easy to have a rule telling isel to avoid matching MOV32mi
-if the immediate has more than some fixed number of uses. It's more involved
-to teach the register allocator how to do late folding to recover from
-excessive register pressure.
