Chris Lattner 4c493d9a58 Don't call getAnalysisUsage unless -debug-pass is enabled. This speeds 
up the passmgr by avoiding useless work.

Dan Gohman c731c97fac Use empty() member functions when that's what's being tested for instead 
of comparing begin() and end().

Anton Korobeynikov 5849a625ff - Use correct header for SCEV inside LoopPass.cpp 
- Move SCEVExpander::expand() out-of-line workarounding possible toolchain bug

Devang Patel cc2b233b62 Introduce Simple Analysis interface for loop passes. 
Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

 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.
