Correct ordering of loads/stores.

Summary:
Aiming to correct the ordering of loads/stores. This patch changes the
insert point for loads to the position of the first load.
It updates the ordering method for loads to insert before, rather than after.

Before this patch the following sequence:
"load a[1], store a[1], store a[0], load a[2]"
Would incorrectly vectorize to "store a[0,1], load a[1,2]".
The correctness check was assuming the insertion point for loads is at
the position of the first load, when in practice it was at the last
load. An alternative fix would have been to invert the correctness check.
The current fix changes insert position but also requires reordering of
instructions before the vectorized load.

Updated testcases to reflect the changes.

Dehao Chen [Mon, 11 Jul 2016 16:48:54 +0000 (16:48 +0000)]
Implement callsite-hotness based inline cost for Sample-based PGO

Summary:
For sample-based PGO, using BFI to calculate callsite count is sometime not accurate. This is because with sampling based approach, if a callsite resides in a hot loop deeply nested in a bunch of cold branches, the callsite's BFI frequency would be inaccurately calculated due to lack of samples in the cold branch.

E.g.

if (A1 && A2 && A3 && ..... && A10) {
  for (i=0; i < 100000000; i++) {
    callsite();
  }
}

Assume that A1 to A100 are all 100% taken, and callsite has 1000 samples and thus is considerred hot. Because the loop's trip count is huge, it's normal that all branches outside the loop has no sample at all. As a result, we can only use static branch probability to derive the the frequency of the loop header. Assuming that static heuristic thinks each branch is 50% taken, then the count calculated from BFI will be 1/(2^10) of the actual value.

In order to get more accurate callsite count, we directly annotate the weight on the call instruction, and directly use it when checking callsite hotness.

Note that this mechanism can also be shared by instrumentation based callsite hotness analysis. The side benefit is that it breaks the dependency from Inliner to BFI as call count is embedded in the IR.

the Instruction is a call-site.

This is now more in line with getModRefInfo generally: it returns Mod when

8 years ago[cmake] Change lli-child-target to use add_llvm_utility instead of add_llvm_executable.
Michael Gottesman [Sun, 10 Jul 2016 02:43:50 +0000 (02:43 +0000)]
[cmake] Change lli-child-target to use add_llvm_utility instead of add_llvm_executable.

We are currently using add_llvm_utility for executable targets that:

1. Are built by default.
2. Used for testing.
3. Are not installed by default.

Originally, lli-child-target used add_llvm_tool instead of add_llvm_executable
directly. This was changed so that lli-child-target would not be installed. This
was good since this is only used for testing and should never be installed for
users. This also had the unfortunate side effect that one can never turn off the
building of lli-child-target by default, a regression for projects that by
default do not want to compile any LLVM tools beyond tablegen/llvm-config.

This patch changes lli-child-target to use add_llvm_utility. This makes sense
since:

1. lli-child-target matches the semantics of executables created with
add_llvm_utility.
2. We fix the regression since now one can use the flag LLVM_BUILD_UTILS to
eliminate default compilation.
