- Required software to compile.
- Optional software to compile.
- Required software for certain *contributor* activities (like
  regenerating configure scripts).

Also we need to mention that there are multiple options for build
systems, and the differences.

7 years agoFix the aggressive anti-dep breaker's subregister definition handling
Hal Finkel [Wed, 26 Feb 2014 20:20:30 +0000 (20:20 +0000)]
Fix the aggressive anti-dep breaker's subregister definition handling

The aggressive anti-dependency breaker scans instructions, bottom-up, within the
scheduling region in order to find opportunities where register renaming can
be used to break anti-dependencies.

Unfortunately, the aggressive anti-dep breaker was treating a register definition
as defining all of that register's aliases (including super registers). This behavior
is incorrect when the super register is live and there are other definitions of
subregisters of the super register.

For example, given the following sequence:

%CR2EQ<def> = CROR %CR3UN, %CR3UN<kill>
%CR2GT<def> = IMPLICIT_DEF
%X4<def> = MFOCRF8 %CR2

the analysis of the first subregister definition would work as expected:
Anti:   %CR2GT<def> = IMPLICIT_DEF
        Def Groups: CR2GT=g194->g0(via CR2)
        Antidep reg: CR2GT (zero group)
        Use Groups:

but the analysis of the second one would not:
Anti:   %CR2EQ<def> = CROR %CR3UN, %CR3UN<kill>
        Def Groups: CR2EQ=g195
        Antidep reg: CR2EQ
        Rename Candidates for Group g195: ...

because, when processing the %CR2GT<def>, we'd mark all super registers of
%CR2GT (%CR2 in this case) as defined. As a result, when processing
%CR2EQ<def>, %CR2 no longer appears to be live, and %CR2EQ<def>'s group is not
%unioned with the %CR2 group.

I don't have an in-tree test case for this yet (and even if I did, I don't have
a small one).

[CMake] Use target_link_libraries(INTERFACE|PRIVATE) on CMake-2.8.12 to increase opportunity for parallel build.

target_link_libraries(INTERFACE) doesn't bring inter-target dependencies in add_library,

It makes most libraries can be built in parallel.

target_link_libraries(PRIVATE) is used to shaared library.
Each dependent library is linked to the target.so, and its user will not see its grandchildren.
For example,

  - libclang.so has sufficient libclang*.a(s).
  - c-index-test requires just only libclang.so.

There are two possible inputs to the required alignment of a memory
transfer intrinsic: the alignment constraints of the source and the

constraints of the other side. Use this to simplify the logic feeding
into alignment computation for unsplit transfers.

Also, hoist the clamp of the magical zero alignment for these intrinsics
to the more customary one alignment early. This lets several other
conditions melt away.

No functionality changed. There is a further improvement this exposes

The primary change is to just rely on uge for checking that the offset
is within the allocation size. This removes the explicit checks against
isNegative which were terribly error prone (including the reversed logic
that led to PR18615) and prevented us from supporting stack allocations
larger than half the address space.... Ok, so maybe the latter isn't
*common* but it's a silly restriction to have.

Also, we used to try to support a PHI node which loaded from before the
start of the allocation if any of the loaded bytes were within the
allocation. This doesn't make any sense, we have never really supported
loading or storing *before* the allocation starts. The simplified logic
just doesn't care.

We continue to allow loading past the end of the allocation in part to
support cases where there is a PHI and some loads are larger than others
and the larger ones reach past the end of the allocation. We could solve
this a different and more conservative way, but I'm still somewhat
paranoid about this.
