What we really know is that the rm_Int instructions don't load the

7 years ago[PM/AA] Hoist the AliasResult enum out of the AliasAnalysis class.
Chandler Carruth [Mon, 22 Jun 2015 02:16:51 +0000 (02:16 +0000)]
[PM/AA] Hoist the AliasResult enum out of the AliasAnalysis class.

This will allow classes to implement the AA interface without deriving
from the class or referencing an internal enum of some other class as
their return types.

Also, to a pretty fundamental extent, concepts such as 'NoAlias',
'MayAlias', and 'MustAlias' are first class concepts in LLVM and we
aren't saving anything by scoping them heavily.

My mild preference would have been to use a scoped enum, but that
feature is essentially completely broken AFAICT. I'm extremely
disappointed. For example, we cannot through any reasonable[1] means
construct an enum class (or analog) which has scoped names but converts
to a boolean in order to test for the possibility of aliasing.

[1]: Richard Smith came up with a "solution", but it requires class
templates, and lots of boilerplate setting up the enumeration multiple
times. Something like Boost.PP could potentially bundle this up, but
even that would be quite painful and it doesn't seem realistically worth
it. The enum class solution would probably work without the need for
a bool conversion.

[PM/AA] Rework the names and comments in AliasSetTracker to more

While these two enums do track mod/ref information and aliasing
information, they don't represent the exact same things as either the
mod/ref enums or the alias result enum in AA. They're definitions are
dominated by the structure of their lattice and the bit's various
semantics. This patch just calls them what they are and tries to spell
out usefully distinct names for these things.

This will clear the path for using a raw unscoped enum to represent some
of these concepts across LLVM's analysis library.

AsmPrinter: Rewrite initialization of DbgVariable, NFC

There are three types of `DbgVariable`:
  - alloca variables, created based on the MMI table,
  - register variables, created based on DBG_VALUE instructions, and
  - optimized-out variables.

This commit reconfigures `DbgVariable` to make it easier to tell which
kind we have, and make initialization a little clearer.

For MMI/alloca variables, `FrameIndex.size()` must always equal
`Expr.size()`, and there shouldn't be an `MInsn`.  For register
variables (with a `MInsn`), `FrameIndex` must be empty, and `Expr`
should have 0 or 1 element depending on whether it has a complex
expression (registers with multiple locations use `DebugLocListIndex`).
Optimized-out variables shouldn't have any of these fields.

Moreover, this separates DBG_VALUE initialization until after the
variable is created, simplifying logic in a future commit that changes
`collectVariableInfo()` to stop creating empty .debug_loc entries/lists.

Switch lowering: add heuristic for filling leaf nodes in the weight-balanced binary search tree

Sparse switches with profile info are lowered as weight-balanced BSTs. For

end up in a tree by itself, bringing it closer to the top.

However, a leaf in this BST can contain up to 3 cases, and having a single

unnecessarily high.

LowerSwitch: Avoid some undefined behaviour

When a case of INT64_MIN was followed by a case that was greater than
zero, we were overflowing a signed integer here. Since we've sorted
the cases here anyway (and thus currentValue must be greater than
nextValue) it's simple enough to avoid this by using addition rather
than subtraction.

7 years agoImprove error handling of getRelocationAddend.
Rafael Espindola [Fri, 19 Jun 2015 20:58:43 +0000 (20:58 +0000)]
Improve error handling of getRelocationAddend.

This patch changes getRelocationAddend to use ErrorOr and considers it an error
to try to get the addend of a REL section.

If, for example, a x86_64 file has a REL section, that file is corrupted and
we should reject it.

Using ErrorOr is not ideal since we check the section type once per relocation
instead of once per section.

Checking once per section would involve getRelocationAddend just asserting and
callers checking the section before iterating over the relocations.

In any case, this is an improvement and includes a test.
