2018-10-04[clang] Add the exclude_from_explicit_instantiation attributeLouis Dionne
Summary: This attribute allows excluding a member of a class template from being part of an explicit template instantiation of that class template. This also makes sure that code using such a member will not take for granted that an external instantiation exists in another translation unit. The attribute was discussed on cfe-dev at [1] and is primarily motivated by the removal of always_inline in libc++ to control what's part of the ABI (see links in [1]).

2018-10-04[llvm-mca] Move field 'AllowZeroMoveEliminationOnly' to class RegisterFile. NFC.Andrea Di Biagio
Flag 'AllowZeroMoveEliminationOnly' should have been a property of the PRF, and not set at register granularity. This change also restricts move elimination to writes that update a full physical register. We assume that there is a strong correlation between logical registers that allow move elimination, and how those same registers are allocated to physical registers by the register renamer. This is still a no functional change, because this experimental code path is disabled for now. This is done in preparation for another patch that will add the ability to describe how move elimination works in scheduling models.

2018-10-04[clangd] Dex: FALSE iterator, peephole optimizations, fix AND bugSam McCall
Summary: The FALSE iterator will be used in a followup patch to fix a logic bug in Dex (currently, tokens that don't have posting lists in the index are simply dropped from the query, changing semantics). It can usually be optimized away, so added the following opmitizations: - simplify booleans inside AND/OR - replace effectively-empty AND/OR with booleans - flatten nested AND/ORs While working on this, found a bug in the AND iterator: its constructor sync() assumes that ReachedEnd is set if applicable, but the constructor never sets it. This crashes if a non-first iterator is nonempty.

2018-10-04[RISCV] Bugfix for floats passed on the stack with the ILP32 ABI on RV32FAlex Bradbury
f32 values passed on the stack would previously cause an assertion in unpackFromMemLoc.. This would only trigger in the presence of the F extension making f32 a legal type. Otherwise the f32 would be legalized. This patch fixes that by keeping LocVT=f32 when a float is passed on the stack. It also adds test coverage for this case, and tests that also demonstrate lw/sw/flw/fsw will be selected when most profitable. i.e. there is no unnecessary i32<->f32 conversion in registers.

2018-10-03[ELF] Fix crash on invalid undefined local symbolsShoaib Meenai
r320770 made LLD handle invalid DSOs where local symbols were found in the global part of the symbol table. Unfortunately, it didn't handle the case where those local symbols were also undefined, and r326242 exposed an assertion failure in that case. Just warn on that case instead of crashing, by moving the local binding check before the undefined symbol addition. The input file for the test is crafted by hand, since I don't know of any tool that would produce such a broken DSO. I also don't understand what it even means for a symbol to be undefined but have STB_LOCAL binding - I don't think that combination makes any sense - but we have found broken DSOs of this nature that we were linking against. I've included detailed instructions on how to produce the DSO in the test. Differential Revision: https://reviews.llvm.org/D52815
