History

Jim Grosbach b56ce8171e Add entries for Expanding atomic intrinsics to libcalls. Just a placeholder

for the moment. The implementation of the libcall will follow.

Currently, the llvm-gcc knows when the intrinsics can be correctly handled by
the back end and only generates them in those cases, issuing libcalls directly
otherwise. That's too much coupling. The intrinsics should always be
generated and the back end decide how to handle them, be it with a libcall,
inline code, or whatever. This patch is a step in that direction.

Analysis

A few more places where SCEVExpander bits need to skip over debug intrinsics

AsmParser

Eliminate the restriction that the array size in an alloca must be i32.

Bitcode

Speedup bitcode writer. Do not walk all values for all functions to emit function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen.
