Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.

Evan Cheng 2818fdd019 Fix some brittle code. Watch out for cases where register scavenger is pointing to deleted instructions.
