* [DebugInfo] Do not generate address info for removed debug labels.Hsiangkai Wang2018-09-252-4/+42
| | | | | | | | | | | | | In some senario, LLVM will remove llvm.dbg.labels in IR. For example, when the labels are in unreachable blocks, these labels will not be generated in LLVM IR. In the case, these debug labels will have address zero as their address. It is not legal address for debugger to set breakpoints or query sources. So, the patch inhibits the address info (DW_AT_low_pc) of removed labels. Differential Revision: https://reviews.llvm.org/D51908 llvm-svn: 342943
* [MachineCopyPropagation] Reimplement CopyTracker in terms of register unitsJustin Bogner2018-09-251-54/+58
| | | | | | | | | | | | Change the copy tracker to keep a single map of register units instead of 3 maps of registers. This gives a very significant compile time performance improvement to the pass. I measured a 30-40% decrease in time spent in MCP on x86 and AArch64 and much more significant improvements on out of tree targets with more registers.

* [MachineCopyPropagation] Rework how we manage RegMask clobbersJustin Bogner2018-09-251-35/+23
| | | | | | | | | | | | | | | | Instead of updating the CopyTracker's maps each time we come across a RegMask, defer checking for this kind of interference until we're actually trying to propagate a copy. This avoids the need to repeatedly iterate over maps in the cases where we don't end up doing any work. This is a slight compile time improvement for MachineCopyPropagation as is, but it also enables a much bigger improvement that I'll follow up with soon.

* [ORC] Switch to asynchronous resolution in JITSymbolResolver.Lang Hames2018-09-2510-92/+152
| | | | | | | | | | | | | | | | | | | Asynchronous resolution (where the caller receives a callback once the requested set of symbols are resolved) is a core part of the new concurrent ORC APIs. This change extends the asynchronous resolution model down to RuntimeDyld, which is necessary to prevent deadlocks when compiling/linking on a fixed number of threads: If RuntimeDyld's linking process were a blocking operation, then any complete K-graph in a program will require at least K threads to link in the worst case, as each thread would block waiting for all the others to complete. Using callbacks instead allows the work to be passed between dependent threads until it is complete. For backwards compatibility, all existing RuntimeDyld functions will continue to operate in blocking mode as before. This change will enable the introduction of a new async finalization process in a subsequent patch to enable asynchronous JIT linking. llvm-svn: 342939

* [compiler-rt] [builtins] Add logb/logbf/logbl methods to compiler-rt to ↵Jordan Rupprecht2018-09-249-10/+282
| | | | | | | | | | | | | | | | | | | | | | | avoid libm dependencies when possible. Summary: The complex division builtins (div?c3) use logb methods from libm to scale numbers during division and avoid rounding issues. However, these come from libm, meaning anyone that uses --rtlib=compiler-rt also has to include -lm. Implement logb* methods for standard ieee 754 floats so we can avoid -lm on those platforms, falling back to the old behavior (using either logb() or `__builtin_logb()`) when not supported. These new methods are defined internally as `__compiler_rt_logb` so as not to conflict with the libm definitions in any way. This fixes just the libm methods mentioned in PR32279 and PR28652. libc is still required, although that seems to not be an issue. Note: this is proposed as an alternative to just adding -lm: D49330.

| | | | | | | | | | | | | | | | | | | | | | | Summary: The target-select-so-path test might hang on some platforms. The reason of that behavior was in incorrect usage of Filecheck and lldb-mi processes. Instead of redirecting lldb-mi's output to Filecheck, we should run lldb-mi session, finish the session, collect its output and then pass it to Filecheck. Also, this patch adds a timer to the test to prevent it from hanging in the future.
