7 years agoIR: Change MDFile to directly store the filename/directory
Duncan P. N. Exon Smith [Fri, 20 Feb 2015 20:35:17 +0000 (20:35 +0000)]
IR: Change MDFile to directly store the filename/directory

In the old (well, current) schema, there are two types of file
references: untagged and tagged (the latter references the former).

    !0 = !{!"filename", !"/directory"}
    !1 = !{!"0x29", !1} ; DW_TAG_file_type [filename] [/directory]

The interface to `DIBuilder` universally takes the tagged version,
described by `DIFile`.  However, most `file:` references actually use
the untagged version directly.

In the new hierarchy, I'm merging this into a single node: `MDFile`.

Originally I'd planned to keep the old schema unchanged until after I
moved the new hierarchy into place.

However, it turns out to be trivial to make `MDFile` match both nodes at
the same time.

  - Anyone referencing !1 does so through `DIFile`, whose implementation
    I need to gut anyway (as I do the rest of the `DIDescriptor`s).
  - Anyone referencing !0 just references an `MDNode`, and expects a
    node with two `MDString` operands.

This commit achieves that, and updates all the testcases for the parts
of the new hierarchy that used the two-node schema (I've replaced the
untagged nodes with `distinct !{}` to make the diff clear (otherwise the
metadata all gets renumbered); it might be worthwhile to come back and
delete those nodes and renumber the world, not sure).

7 years agoIntroduce bitset metadata format and bitset lowering pass.
Peter Collingbourne [Fri, 20 Feb 2015 20:30:47 +0000 (20:30 +0000)]
Introduce bitset metadata format and bitset lowering pass.

This patch introduces a new mechanism that allows IR modules to co-operatively
build pointer sets corresponding to addresses within a given set of
globals. One particular use case for this is to allow a C++ program to
efficiently verify (at each call site) that a vtable pointer is in the set
of valid vtable pointers for the class or its derived classes. One way of
doing this is for a toolchain component to build, for each class, a bit set
that maps to the memory region allocated for the vtables, such that each 1
bit in the bit set maps to a valid vtable for that class, and lay out the
vtables next to each other, to minimize the total size of the bit sets.

The patch introduces a metadata format for representing pointer sets, an
'@llvm.bitset.test' intrinsic and an LTO lowering pass that lays out the globals
and builds the bitsets, and documents the new feature.

[GC, RewriteStatepointsForGC] Style cleanup and bug fix

When doing style cleanup, I noticed a minor bug in this code.  If we have a pointer that we think is unused after a statepoint and thus doesn't need relocation, we store a null pointer into the alloca we're about to promote.  This helps turn a mistake in liveness analysis into an easily debuggable crash.  It turned out this code had never been updated to handle invoke statepoints.

There's no test for this.  Without a bug in liveness, it appears impossible to make this trigger in a way which is visible in the resulting IR.  We might store the null, but when promoting the alloca, there will be no uses and thus nothing to test against.  Suggestions on how to test are very welcome.
