2013-03-18Include '.test' suffix in target specific lit configs that need itDavid Blaikie
Apparently my final cleanup to use a relevant suffix for these tests before committing r176831 caused them to stop running since lit wasn't configured to run tests with that suffix in those directories (why don't we just have a global suffix list?). So, add the suffix to the relevant directories & fix the test that has bitrotted over the last week due to my debug info schema changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177315 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-20Fix thumbv5e frame lowering assertion failure.Logan Chien
It is possible that frame pointer is not found in the callee saved info, thus FramePtrSpillFI may be incorrect if we don't check the result of hasFP(MF). Besides, if we enable the stack coloring algorithm, there will be an assertion to ensure the slot is live. But in the test case, %var1 is not live in the prologue of the function, and we will get the assertion failure. Note: There is similar code in ARMFrameLowering.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175616 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Use the 'count' attribute to calculate the upper bound of an array.Bill Wendling
The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange. We can also better handle an unbound array by setting the count to -1 instead of the lower bound to 1 and upper bound to 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169312 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Add a 'count' field to the DWARF subrange.Bill Wendling
The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array. When it's -1, then the array is unbounded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169218 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Fix the remaining TCL-style quotes found in the testsuite. This isChandler Carruth
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. =/ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159547 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-02Convert the uses of '|&' to use '2>&1 |' instead, which works on oldChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159544 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-02Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth
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. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8

There are no dg.exp files left in the test suite so this code is no longer required. test/lit.cfg is now much shorter and clearer * Removed a lot of duplicate code in lit.local.cfg files that need access to the root configuration, by adding a "root" attribute to the TestingConfig object.

it fixes the dragonegg self-host (it looks like gcc is miscompiled). Original commit messages: Eliminate LegalizeOps' LegalizedNodes map and have it just call RAUW on every node as it legalizes them. This makes it easier to use hasOneUse() heuristics, since unneeded nodes can be removed from the DAG earlier. Make LegalizeOps visit the DAG in an operands-last order. It previously used operands-first, because LegalizeTypes has to go operands-first, and LegalizeTypes used to be part of LegalizeOps, but they're now split. The operands-last order is more natural for several legalization tasks. For example, it allows lowering code for nodes with floating-point or vector constants to see those constants directly instead of seeing the lowered form (often constant-pool loads). This makes some things somewhat more complicated today, though it ought to allow things to be simpler in the future. It also fixes some bugs exposed by Legalizing using RAUW aggressively. Remove the part of LegalizeOps that attempted to patch up invalid chain operands on libcalls generated by LegalizeTypes, since it doesn't work with the new LegalizeOps traversal order. Instead, define what LegalizeTypes is doing to be correct, and transfer the responsibility of keeping calls from having overlapping calling sequences into the scheduler. Teach the scheduler to model callseq_begin/end pairs as having a physical register definition/use to prevent calls from having overlapping calling sequences. This is also somewhat complicated, though there are ways it might be simplified in the future. This addresses rdar://9816668, rdar://10043614, rdar://8434668, and others.
