* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-2/+2
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
* Do not use typeinfo to identify pass in pass manager.Devang Patel2007-05-011-0/+5

| | | | llvm-svn: 36452
* Use BitVector instead of vector<bool> which can be extremely slow.Evan Cheng2007-02-151-1/+1

* Detemplatize the Statistic class. The only type it is instantiated withChris Lattner2006-12-061-3/+3

* Fix Regression/CodeGen/Generic/2006-09-02-LocalAllocCrash.ll on X86.Chris Lattner2006-09-031-6/+11
| | | | | | | Just because an alias of a register is available, it doesn't mean that we can arbitrarily evict the register. llvm-svn: 30064

* Fix a recent regression in Applications/sgefa that Alkis pointed out to me.Chris Lattner2004-06-161-2/+2
| | | | | | | | The vector may actually be empty if the register that we are marking as recently used is not actually allocatable. This happens for physical registers that are not allocatable, like the ST(x) registers on X86. llvm-svn: 14195

* Refactor rewinding code for finding the first terminator of a basicAlkis Evlogimenos2004-02-231-5/+1
| | | | | | | | | | | | block into MachineBasicBlock::getFirstTerminator(). This also fixes a bug in the implementation of the above in both RegAllocLocal and InstrSched, where instructions where added after the terminator if the basic block's only instruction was a terminator (it shouldn't matter for RegAllocLocal since this case never occurs in practice). llvm-svn: 11748
