2012-08-01Initial commit of new FileOutputBuffer support class. Nick Kledzik
Since the llvm::sys::fs::map_file_pages() support function it relies on is not yet implemented on Windows, the unit tests for FileOutputBuffer are currently conditionalized to run only on unix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161099 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-31Compute instruction depths through the current trace.Jakob Stoklund Olesen
Assuming infinite issue width, compute the earliest each instruction in the trace can issue, when considering the latency of data dependencies. The issue cycle is record as a 'depth' from the beginning of the trace. This is half the computation required to find the length of the critical path through the trace. Heights are next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161074 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-31MachineSink: Sort the successors before trying to find SuccToSinkTo.Manman Ren
One motivating example is to sink an instruction from a basic block which has two successors: one outside the loop, the other inside the loop. We should try to sink the instruction outside the loop. rdar://11980766 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161062 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-31Bring TinyPtrVector under test. Somehow we never picked up unit testsChandler Carruth
for this class. These tests exercise most of the basic properties, but the API for TinyPtrVector is very strange currently. My plan is to start fleshing out the API to match that of SmallVector, but I wanted a test for what is there first. Sadly, it doesn't look reasonable to just re-use the SmallVector tests, as this container can only ever store pointers, and much of the SmallVector testing is to get construction and destruction right. Just to get this basic test working, I had to add value_type to the interface. While here I found a subtle bug in the combination of 'erase', 'begin', and 'end'. Both 'begin' and 'end' wanted to use a null pointer to indicate the "end" iterator of an empty vector, regardless of whether there is actually a vector allocated or the pointer union is null. Everything else was fine with this except for erase. If you erase the last element of a vector after it has held more than one element, we return the end iterator of the underlying SmallVector which need not be a null pointer. Instead, simply use the pointer, and poniter + size() begin/end definitions in the tiny case, and delegate to the inner vector whenever it is present. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161024 91177308-0d34-0410-b5e6-96231b3b80d8

This lets traces include the final iteration of a nested loop above the center block, and the first iteration of a nested loop below the center block.

Empty macro arguments at the end of the list should be as-if not specified at all, but those in the middle of the list need to be kept so as not to screw up the positional numbering. E.g.: .macro foo foo_-bash___: nop .endm foo 1, 2, 3, 4 foo 1, , 3, 4 Should create two labels, "foo_1_2_3_4" and "foo_1__3_4". rdar://11948769 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161002 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-30Move the SmallVector unit tests to be type-parameterized so that we canChandler Carruth
test more than a single instantiation of SmallVector. Add testing for 0, 1, 2, and 4 element sized "small" buffers. These appear to be essentially untested in the unit tests until now. Fix several tests to be robust in the face of a '0' small buffer. As a consequence of this size buffer, the growth patterns are actually observable in the test -- yes this means that many tests never caused a grow to occur before. For some tests I've merely added a reserve call to normalize behavior. For others, the growth is actually interesting, and so I captured the fact that growth would occur and adjusted the assertions to not assume how rapidly growth occured. Also update the specialization for a '0' small buffer length to have all the same interface points as the normal small vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161001 91177308-0d34-0410-b5e6-96231b3b80d8
