This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

Fix SCEV forgetMemoizedResults should search and destroy backedge exprs.2013-03-26T03:14:53ZAndrew Trickatrick@apple.com2013-03-26T03:14:53Zurn:sha1:e74c2e86cb405963ba9c4043a1d0ca00b8f85fbe
Fixes PR15570: SEGV: SCEV back-edge info invalid after dead code removal.
Indvars creates a SCEV expression for the loop's back edge taken
count, then determines that the comparison is always true and
removes it.
When loop-unroll asks for the expression, it contains a NULL
SCEVUnknkown (as a CallbackVH).
forgetMemoizedResults should invalidate the loop back edges expression.

Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID2012-12-30T02:33:22ZDmitri Gribenkogribozavr@gmail.com2012-12-30T02:33:22Zurn:sha1:a6542923b8ad94d791a12d3d5ae3e62a611f0383
This is done to avoid odd test failures, like the one fixed in r171243.

Add a check to the test Analysis/ScalarEvolution/2010-09-03-RequiredTransitive.ll2012-12-30T01:42:34ZDmitri Gribenkogribozavr@gmail.com2012-12-30T01:42:34Zurn:sha1:a51edf0986567bd81e261950f75a72b7462b2274
This test did not test anything at all (except for opt crashing, but that was
not the reason why it was added).

I really need to find a way to automate this, but I can't come up with a regex
that has no false positives while handling tricky cases like custom check
prefixes.

Stay rational; don't assert trying to take the square root of a negative value.2012-08-01T09:14:36ZNick Lewyckynicholas@mxc.ca2012-08-01T09:14:36Zurn:sha1:6ce2471806316ae9e1c7715f703c380d4f4311b6
If it's negative, the loop is already proven to be infinite. Fixes PR13489!

Fix the remaining TCL-style quotes found in the testsuite. This is2012-07-02T19:09:46ZChandler Carruthchandlerc@gmail.com2012-07-02T19:09:46Zurn:sha1:1de43ede8904e08de37f601c9bab0b70f71156e1
another mechanical change accomplished though the power of terrible Perl
scripts.
I have manually switched some "s to 's to make escaping simpler.
While I started this to fix tests that aren't run in all configurations,
the massive number of tests is due to a really frustrating fragility of
our testing infrastructure: things like 'grep -v', 'not grep', and
'expected failures' can mask broken tests all too easily.
Essentially, I'm deeply disturbed that I can change the testsuite so
radically without causing any change in results for most platforms. =/

Convert the uses of '|&' to use '2>&1 |' instead, which works on old2012-07-02T18:37:59ZChandler Carruthchandlerc@gmail.com2012-07-02T18:37:59Zurn:sha1:49589f0d0e35f643e697ab7ae8a51a530d38b0d8
versions of Bash. In addition, I can back out the change to the lit
built-in shell test runner to support this.
This should fix the majority of fallout on Darwin, but I suspect there
will be a few straggling issues.

Convert all tests using TCL-style quoting to use shell-style quoting.2012-07-02T12:47:22ZChandler Carruthchandlerc@gmail.com2012-07-02T12:47:22Zurn:sha1:4177e6fff50552908bab510f1e896fa974a6f155
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.
If anyone is maintaining large out-of-tree test trees, feel free to poke
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.
Finally, the test suite runs 33% faster on Linux now. ;]
