- SymConst's are now ALWAYS placed in the start block

[r26236]

[r25823]

- BugFix: cache the newly created memop, not the old one
- BugFix: must search for the Phi-translated load in the predecessors avail set
- BugFix: size of bitset is now equal to the address size (was it before too :-)

[r25720]

- phi-translate the antic sets

[r25719]

- update addesses of nodes due to Lod replacements
- remove unused (and wrong) code
- BugFix: used right condition to stop search of partly redundand Loads
- use Phi-translated addresses for cleanup check
- BugFix: correctly link in newly created memops into the memop chain of the previous blocks
- BugFix: always update the value map

[r25714]

- remove block flags for now, use block marks for marking blocks
- BugFix: fix analysis for IGNORE Stores
- BugFix: fixed creation of partly reduntant Loads: must be done BEFORE gen/kill
- removed now unused code
- kill unreachable blocks before analysis helps greatly and is simple, as we have
  to collect these data anyway

[r25703]

[r25700]

[r25699]

  exist

[r25698]

- BugFix: correctly handle different modes when creating a Phi (CopyB lowerer always uses unsigned modes :-()
- Handle loads from constant entities

[r25675]

  use local out edges (like old implementation)
- BugFix: always build Phi nodes on merge points: the lazy techniques did not
  work that simple ...
- in rare cases Loads and Stores might have NO memory

[r25663]

- only calculate avail_out for the blocks in first step (like GVN-PRE)
- correctly update avail_out during load_insert
- do NOT WAW same stores

[r25660]

[r25585]

[r25529]

- find_definition() can fail if memory is accessed using different modes

[r25472]

- skip keep-alive edges
- fixed: do not insert of fully redundand loads (already handled earlier)
- partly fixed: End block is not reached using out-edges ...

[r25465]

  are in the same block
- find_definition() must check real dominance for values, not only for blocks

[r25464]

 - fixed rerouting if the last-mem is in a previous block
 - a Phi is it's own memory

[r25415]

 - use rbitset_cpy(): this fixes the wrong size of the former memcpy()
 - if no memops are found, skip the analysis (which would crash either)
 - do not reroute memory if the last memory op is from a previous block
