This makes it easier to link against LLVM libs, especially if you are using

Disable code/data region symbols on ELF targets, where different mapping symbols are used for ARM/Thumb mode code. This should only be re-enabled once we have a solution to properly distinguish these.

Pass the correct jobs and threads information to the builder.
We were underutilizing the number of jobs and threads specified
by the user.

llvm-svn: 141977

Bit just a bit more verbose about what's going on.  Print options
to make to aid debugging.

llvm-svn: 141976

Add a --no-install option to skip installing components.  This
speeds up the develop/test cycle.

llvm-svn: 141975

And a --no-gcc option to skip dragonegg and gcc builds.
This greatly speeds up the develop/test cycle.

No testcase because this is a bug-fix broken out of a larger optimization patch.

Add X86 TZCNT instruction and patterns to select it. Also added core-avx2 processor which is gcc's name for Haswell.

TableGen infers unmodeled side effects on instructions without a
pattern.  Fix some instruction definitions where that was overlooked.

Also raise an error if a rematerializable instruction has unmodeled side
effects. That doen't make any sense.

llvm-svn: 141929

TableGen will mark any pattern-less instruction as having unmodeled side
effects. This is extra bad for V_SET0 which gets rematerialized a lot.

This was part of the cause for PR11125, but the real bug was fixed
in r141923.

llvm-svn: 141924

When spilling around an instruction with a dead def, remember to add a
value number for the def.

The missing value number wouldn't normally create problems since there
would be an incoming live range as well.  However, due to another bug
we could spill a dead V_SET0 instruction which doesn't read any values.

The missing value number caused an empty live range to be created which
is dangerous since it doesn't interfere with anything.

This fixes part of PR11125.

llvm-svn: 141923

Someone more familiar with LSR should double-check that the extra cast is actually doing the right thing in the overflow cases; I'm not completely confident that's that case.

Enhance the memdep interface so that users can tell the difference between a dependency which cannot be calculated and a path reaching the entry point of the function. This patch introduces isNonFuncLocal, which replaces isUnknown in some cases.
