2008-02-20Unbreak build with gcc 4.3: provide missed includes and silence most ↵Anton Korobeynikov
annoying warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47367 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-20When performing return slot optimization, remember to inform memdep when ↵Owen Anderson
we're removing the memcpy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47364 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Expand ParameterAttributes to 32 bits (in preparationDale Johannesen
for adding alignment info, not there yet). Clean up interfaces to reference ParameterAttributes consistently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47342 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19remove the LowerSelect pass. The last client was the old Sparc backend, ↵Chris Lattner
which is long dead by now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47323 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19remove the lower packed pass. It can never work and even the parts that Chris Lattner
could work don't work fully. This fixes PR1705. Oh yeah, we don't have packed types anymore either ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47322 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Refactor this method a bit, and correct a test that was completely wrong but ↵Owen Anderson
happened to work out anyways. :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47321 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47319 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47318 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Major improvements to yesterday's return slot optimization. Remove some ↵Owen Anderson
unneccessary constraints, and add some others that should have been in from the first place. Document the whole thing better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47315 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19fdiv/frem of undef can produce undef, because the undef operand Chris Lattner
can be a SNaN. We could be more aggressive and turn this into unreachable, but that is less nice, and not really worth it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47313 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Factor the profitability check for return slot optimization out into a ↵Owen Anderson
static function. At some point in the future, this check will become smarter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47310 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19An sret parameter is required to be the first parameter, so there's no need ↵Owen Anderson
to loop over all the parameters of the callee looking for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47309 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Cleanup some of my patches from yesterday. Refactor the check for which xformOwen Anderson
to apply to a memcpy into processInstruction. Also, fix a bug in the check due to missing braces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47307 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Fix Transforms/GVN/memcpy.ll, which Chris broke in r47275 by reordering the ↵Owen Anderson
branches. memcpy's are a kind of CallInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47305 91177308-0d34-0410-b5e6-96231b3b80d8

to Dale for noticing this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47276 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-18Simplify caller updating using a CallSite, asDuncan Sands
requested by Chris. While there, do the same for an existing function committed by someone called "lattner" :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47273 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-18Add support to GVN for performing sret return slot optimization. This means ↵Owen Anderson
that, if an sret function tail calls another sret function, it should pass its own sret parameter to the tail callee, allowing it to fill in the correct return value. llvm-gcc does not emit this by default. Instead, it allocates space in the caller for the sret of the tail call and then uses memcpy to copy the result into the caller's sret parameter. This optimization detects and optimizes that case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47265 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-05Make RenamePass faster by making the 'is this a new phi node'Chris Lattner
check more intelligent. This speeds up mem2reg from 5.29s to 0.79s on a synthetic testcase with tons of predecessors and phi nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46767 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-05Fix a bug compiling PR1978 (perhaps not the only one though) whichChris Lattner
was incorrectly simplifying "x == (gep x, 1, i)" into false, even though i could be negative. As it turns out, all the code to handle this already existed, we just need to disable the incorrect optimization case and let the general case handle it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46739 91177308-0d34-0410-b5e6-96231b3b80d8
