Zola Bridges [Fri, 18 Jan 2019 17:20:46 +0000 (17:20 +0000)]
[clang][slh] add Clang attr no_speculative_load_hardening

Summary:
This attribute will allow users to opt specific functions out of
speculative load hardening. This compliments the Clang attribute
named speculative_load_hardening. When this attribute or the attribute
speculative_load_hardening is used in combination with the flags
-mno-speculative-load-hardening or -mspeculative-load-hardening,
the function level attribute will override the default during LLVM IR
generation. For example, in the case, where the flag opposes the
function attribute, the function attribute will take precendence.
The sticky inlining behavior of the speculative_load_hardening attribute
may cause a function with the no_speculative_load_hardening attribute
to be tagged with the speculative_load_hardening tag in
subsequent compiler phases which is desired behavior since the
speculative_load_hardening LLVM attribute is designed to be maximally
conservative.

If both attributes are specified for a function, then an error will be
thrown.

not visible in llvm/test.

r289662 added the llvm_tool_lto_build lit parameter, there the intent was to
use it with an explicit -DLLVM_TOOL_LTO_BUILD=OFF, which is visible globally.
On the review for that (D27739), a mild preference was expressed for using a
lit parameter over checking the existence of libLTO.dylib. Since that works

gold plugin, switch to that approach.

[Reproducers] Refactor reproducer info

In the original reproducer design, I expected providers to be more
dynamic than they turned out. For example, we don't have any instances
where one provider has multiple files. Additionally, I expected there to
be less locality between capture and replay, with the provider being
defined in one place and the replay code to live in another. Both
contributed to the design of the provider info.

This patch refactors the reproducer info to be something static. This
means less magic strings and better type checking. The new design still
allows for the capture and replay code to live in different places as
long as they both have access to the new statically defined info class.

I didn't completely get rid of the index, because it is useful for (1)
sanity checking and (2) knowing what files are used by the reproducer.

[analyzer] Make sure base-region and its sub-regions are either all alive or all dead.

SymbolReaper now realizes that our liveness analysis isn't sharp enough
to discriminate between liveness of, say, variables and their fields.
Surprisingly, this didn't quite work before: having a variable live only
through Environment (eg., calling a C++ method on a local variable
as the last action ever performed on that variable) would not keep the
region value symbol of a field of that variable alive.

It would have been broken in the opposite direction as well, but both
Environment and RegionStore use the scanReachableSymbols mechanism for finding
live symbols regions within their values, and due to that they accidentally
end up marking the whole chain of super-regions as live when at least one
sub-region is known to be live.

It is now a direct responsibility of SymbolReaper to maintain this invariant,
and a unit test was added in order to make sure it stays that way.
