2011-04-12Add support for line profiling. Very work-in-progress.Nick Lewycky
Use debug info in the IR to find the directory/file:line:col. Each time that location changes, bump a counter. Unlike the existing profiling system, we don't try to look at argv[], and thusly don't require main() to be present in the IR. This matches GCC's technique where you specify the profiling flag when producing each .o file. The runtime library is minimal, currently just calling printf at program shutdown time. The API is designed to make it possible to emit GCOV data later on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129340 91177308-0d34-0410-b5e6-96231b3b80d8

reassociation opportunities are exposed. This fixes a bug where the nested reassociation expects to be the IR to be consistent, but it isn't, because the outer reassociation has disconnected some of the operands. rdar://9167457 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129324 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-11build: Add support for a SHOW_DIAGNOSTICS build variable.Daniel Dunbar
If enabled, this will attempt to use the CC_LOG_DIAGNOSTICS feature I dropped into Clang to print a log of all the diagnostics generated during an individual build (from the top-level). Not sure if this will actually be useful, but for now it is handy for testing the option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129312 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-11Just because a GlobalVariable's initializer is [N x { i32, void ()* }] doesn'tNick Lewycky
mean that it has to be ConstantArray of ConstantStruct. We might have ConstantAggregateZero, at either level, so don't crash on that. Also, semi-deprecate the sentinal value. The linker isn't aware of sentinals so we end up with the two lists appended, each with their "sentinals" on them. Different parts of LLVM treated sentinals differently, so make them all just ignore the single entry and continue on with the rest of the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129307 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-11The default of the dispatch switch statement was to branch to a BB that executedBill Wendling
the 'unwind' instruction. However, later on that instruction was converted into a jump to the basic block it was located in, causing an infinite loop when we get there. It turns out, we get there if the _Unwind_Resume_or_Rethrow call returns (which it's not supposed to do). It returns if it cannot find a place to unwind to. Thus we would get what appears to be a "hang" when in reality it's just that the EH couldn't be propagated further along. Instead of infinitely looping (or calling `unwind', which none of our back-ends support (it's lowered into nothing...)), call the @llvm.trap() intrinsic instead. This may not conform to specific rules of a particular language, but it's rather better than infinitely looping. <rdar://problem/9175843&9233582> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129302 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-11Adding support for printing operands symbolically to llvm's public 'C'Kevin Enderby
disassembler API. Hooked this up to the ARM target so such tools as Darwin's otool(1) can now print things like branch targets for example this: blx _puts instead of this: blx #-36 And even print the expression encoded in the Mach-O relocation entried for things like this: movt r0, :upper16:((_foo-_bar)+1234) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129284 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-11Don't add live ranges for sub-registers when clobbering a physical register.Jakob Stoklund Olesen
Both coalescing and register allocation already check aliases for interference, so these extra segments are only slowing us down. This speeds up both linear scan and the greedy register allocator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129283 91177308-0d34-0410-b5e6-96231b3b80d8
