2011-04-21Don't allow per-register spill size and alignment.Jakob Stoklund Olesen
These values were not used for anything. Spill size and alignment is a property of the register class, not the register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129906 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-21In gcov profiling, give all functions an extra unified return block. This isNick Lewycky
necessary since gcov counts transitions between blocks. It can't see if you've run every line in a straight-line function, so we add an edge for it to notice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129905 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-21Add independent controls for whether GCOV profiling should emit .gcno files orNick Lewycky

2011-04-20Permit remat when a virtual register has multiple defs.Jakob Stoklund Olesen
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129882 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-20Fix another case of <rdar://problem/9184212> that only occurs with codeCameron Zwarich
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129878 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-20Prefer cheap registers for busy live ranges.Jakob Stoklund Olesen
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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129864 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-20This should always be signed chars, so use int8_t. This fixes a miscompile whenNick Lewycky
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". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129845 91177308-0d34-0410-b5e6-96231b3b80d8
