* Allow allocatable ranges from global live range splitting to be split again.Jakob Stoklund Olesen2011-04-213-7/+45
| | | | | | | | | | | | | | | | | | | | | These intervals are allocatable immediately after splitting, but they may be evicted because of later splitting. This is rare, but when it happens they should be split again. The remainder intervals that cannot be allocated after splitting still move directly to spilling. SplitEditor::finish can optionally provide a mapping from new live intervals back to the original interval indexes returned by openIntv(). Each original interval index can map to multiple new intervals after connected components have been separated. Dead code elimination may also add existing intervals to the list. The reverse mapping allows the SplitEditor client to treat the new intervals differently depending on the split region they came from. llvm-svn: 129925

* ptx: fix parameter orderingChe-Liang Chiou2011-04-211-4/+1
| | | | | | | | | This patch depends on the prior fix r129908 that changes to use std::find, rather than std::binary_search, on unordered array. Patch by Dan Bailey llvm-svn: 129909

* In gcov profiling, give all functions an extra unified return block. This isNick Lewycky2011-04-211-5/+17

* Permit remat when a virtual register has multiple defs.Jakob Stoklund Olesen2011-04-201-5/+0
| | | | | | | | TII::isTriviallyReMaterializable() shouldn't depend on any properties of the register being defined by the instruction. Rematerialization is going to create a new virtual register anyway. llvm-svn: 129882
* Fix another case of <rdar://problem/9184212> that only occurs with codeCameron Zwarich2011-04-201-31/+44
| | | | | | | generated by llvm-gcc, since llvm-gcc uses 2 i64s for passing a 4 x float vector on ARM rather than an i64 array like Clang. llvm-svn: 129878

* Prefer cheap registers for busy live ranges.Jakob Stoklund Olesen2011-04-204-13/+61
| | | | | | | | | | | | | | On the x86-64 and thumb2 targets, some registers are more expensive to encode than others in the same register class. Add a CostPerUse field to the TableGen register description, and make it available from TRI->getCostPerUse. This represents the cost of a REX prefix or a 32-bit instruction encoding required by choosing a high register. Teach the greedy register allocator to prefer cheap registers for busy live ranges (as indicated by spill weight). llvm-svn: 129864

* This should always be signed chars, so use int8_t. This fixes a miscompile whenNick Lewycky2011-04-201-3/+3
| | | | | | | | llvm is built with unsigned chars where an immediate such as 0xff would be zero extended to 64-bits, turning "cmp $0xff,%eax" into "cmp $0xffffffffffffffff,%eax". llvm-svn: 129845

| | | | | | | | | - There is a minor semantic change here (evidenced by the test change) for Darwin triples that have no version component. I debated changing the default behavior of isOSVersionLT, but decided it made more sense for triples to be explicit. llvm-svn: 129802
