become a problem. My POWER7 development machine has 48 cores, and when running

into problems. lit, by default, will want to run 48 tests in parallel, and
48*48 < 1024, and so many tests fail like this:

terminate called after throwing an instance of 'std::system_error'

what():  Resource temporarily unavailable
or lit fails like this when launching a test:

OSError: [Errno 11] Resource temporarily unavailable

lit can easily detect this situation and attempt to repair it before launching
tests (by raising the soft process limit to something that will allow ncpus^2
threads to be created), and should do so to prevent spurious test failures.

Note that fp128 is not yet handled, because it is relatively rare, and is a
bit trickier, because of the fact that l.dfr would operate on the sign bit of

Arnaud A. de Grandmaison [Thu, 1 Oct 2015 14:54:31 +0000 (14:54 +0000)]
[InstCombine] Remove trivially empty lifetime start/end ranges.

Summary:
Some passes may open up opportunities for optimizations, leaving empty
lifetime start/end ranges. For example, with the following code:

    void foo(char *, char *);
    void bar(int Size, bool flag) {
      for (int i = 0; i < Size; ++i) {
        char text[1];
        char buff[1];
        if (flag)
          foo(text, buff); // BBFoo
      }
    }

the loop unswitch pass will create 2 versions of the loop, one with
flag==true, and the other one with flag==false, but always leaving
the BBFoo basic block, with lifetime ranges covering the scope of the for
loop. Simplify CFG will then remove BBFoo in the case where flag==false,
but will leave the lifetime markers.

This patch teaches InstCombine to remove trivially empty lifetime marker
ranges, that is ranges ending right after they were started (ignoring
debug info or other lifetime markers in the range).

This fixes PR24598: excessive compile time after r234581.

Fix performance problem in long-running SectionMemoryManagers

Summary:
Without this patch, the memory manager would call `mprotect` on every memory
region it ever allocated whenever it wanted to finalize memory (i.e. not just
the ones it just allocated). This caused terrible performance problems for
long running memory managers. In one particular compile heavy julia benchmark,
we were spending 50% of time in `mprotect` if running under MCJIT.

Fix this by splitting allocated memory blocks into those on which memory
permissions have been set and those on which they haven't and only running
`mprotect` on the latter.
