Chris Lattner 72b503bcad Compile X << 1 (where X is a long-long) to:
addl %ecx, %ecx
        adcl %eax, %eax

instead of:

        movl %ecx, %edx
        addl %edx, %edx
        shrl $31, %ecx
        addl %eax, %eax
        orl %ecx, %eax

and to:

        addc r5, r5, r5
        adde r4, r4, r4

instead of:

        slwi r2,r9,1
        srwi r0,r11,31
        slwi r3,r11,1
        or r2,r0,r2

on PPC.

Evan Cheng 45fe3bc72c Added support for machine specific constantpool values. These are useful for
representing expressions that can only be resolved at link time, etc.

Chris Lattner 1d7ec20a4d An sinkable instruction may exist with uses, if those uses are in dead blocks.

Evan Cheng 1ec61ba00a 1) With X86 lowering change, the following can no longer happen since
the branch's chain is also produced by cmp.
          [ch, r : ld]
             ^ ^
             | |
      [XX]--/   \- [flag : cmp]
       ^             ^
       |             |
       \---[br flag]-

Remove an isel check which prevents loads from being folded into cmp / test
instructions.

2) Whenever possible, delete a selected node to allow more load folding
opportunities. Note not all nodes can be deleted after it has been
selected. Some may have simply morphed; some have not changed at all (e.g.
EntryToken).

2006-09-11 02:24:43 +00:00
Evan Cheng 4259a0f654 X86ISD::CMP now produces a chain as well as a flag. Make that the chain
operand of a conditional branch to allow load folding into CMP / TEST
instructions.

Chris Lattner 2e0dfb0b16 This code was trying too hard. By eliminating redundant edges in the CFG
due to switch cases going to the same place, it make #pred != #phi entries,
breaking live interval analysis.

This fixes 458.sjeng on x86 with llc.

Nick Lewycky 9a22d7b60f Replace EquivalenceClasses with a custom-built data structure. Many common
operations (like findProperties) should be faster, at the expense of
unionSets being slower in cases that are rare in practise.

Don't erase a dead Instruction. This fixes a memory corruption issue.
