Chandler Carruth [Thu, 5 Jul 2012 11:06:22 +0000 (11:06 +0000)]
Finish fixing the MachineOperand hashing, providing a nice modern
hash_value overload for MachineOperands. This addresses a FIXME
sufficient for me to remove it, and cleans up the code nicely too.

The important changes to the hashing logic:
- TargetFlags are now included in all of the hashes. These were complete
  missed.
- Register operands have their subregisters and whether they are a def
  included in the hash.
- We now actually hash all of the operand types. Previously, many
  operand types were simply *dropped on the floor*. For example:
  - Floating point immediates
  - Large integer immediates (>64-bit)
  - External globals!
  - Register masks
  - Metadata operands
- It removes the offset from the block-address hash; I'm a bit
  suspicious of this, but isIdenticalTo doesn't consider the offset for
  black addresses.

Any patterns involving these entities could have triggered extreme
slowdowns in MachineCSE or PHIElimination. Let me know if there are PRs
you think might be closed now... I'm looking myself, but I may miss
them.

Chandler Carruth [Thu, 5 Jul 2012 10:03:57 +0000 (10:03 +0000)]
The hash function for MI expressions, used by MachineCSE, is really
broken. This patch fixes the superficial problems which lead to the
intractably slow compile times reported in PR13225.

The specific issue is that we were failing to include the *offset* of
a global variable in the hash code. Oops. This would in turn cause all
MIs which were only distinguishable due to operating on different
offsets of a global variable to produce identical hash functions. In
some of the test cases attached to the PR I saw hash table activity
where there were O(1000) probes-per-lookup *on average*. A very few
entries were responsible for most of these probes.

There is still quite a bit more to do here. The ad-hoc layering of data
in MachineOperands makes them *extremely* brittle to hash correctly.
We're missing quite a few other cases, the only ones I've fixed here are
the specific MO types which were allowed through the assert() in
getOffset().

Convert all tests using TCL-style quoting to use shell-style quoting.

This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.
