2009-08-19Make SROA and PredicateSimplifier cope if TargetData is notDan Gohman
available. This is very conservative for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79442 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Use hasDefinitiveInitializer() instead of testing the same thingDan Gohman
by hand, and fix a few places that were using hasInitializer() that appear to depend on the initializer value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79441 91177308-0d34-0410-b5e6-96231b3b80d8

unruly indices for arrays that are members of structs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79337 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-18The attached patches attempt to fix cross builds. For example, if youAnton Korobeynikov
try to use i686-darwin to build for arm-eabi, you'll quickly run into several false assumptions that the target OS must be the same as the host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to help builds like "make check" and the test-suite able to cross compile. Along the way a target of *-unknown-eabi is defined as "Freestanding" so that TARGET_OS checks have something to work with. Patch by Sandeep Patel! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79296 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-17Fix debug output to include a newline after printing a Value, nowDan Gohman
that Value's operator<< doesn't include one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79240 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17Don't access the first element of a potentially emptyDuncan Sands
vector (&Formals[0]). With this change llvm-gcc builds with expensive checking enabled for C, C++ and Fortran. While there, change a std::vector into a SmallVector. This is partly gratuitous, but mostly because not all STL vector implementations define the data method (and it should be faster). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79237 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17Don't crash trying to promote VLAs.Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79226 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-16Fix for PR3016: detect the tricky case, where there are Eli Friedman
unfoldable references to a PHI node in the block being folded, and disable the transformation in that case. The correct transformation of such PHI nodes depends on whether BB dominates Succ, and dominance is expensive to compute here. (Alternatively, it's possible to check whether any uses are live, but that's also essentially a dominance calculation. Another alternative is to use reg2mem, but it probably isn't a good idea to use that in simplifycfg.) Also, remove some incorrect code from CanPropagatePredecessorsForPHIs which is made unnecessary with this patch: it didn't consider the case where a PHI node in BB has multiple uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79174 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-13When InstCombine simplifies a load -> extract element to gep -> load, placeMon P Wang
the new load by the old load instead of by the extract element because a store could have occurred between the load and extract element. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78891 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-12Add contexts to some of the MVT APIs. No functionality change yet, just the ↵Owen Anderson
infrastructure work needed to get the contexts to where they need to be first. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78759 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-08More ProfileInfo improvements.Daniel Dunbar

2009-08-05Privatize the StructType table, which unfortunately involves routing ↵Owen Anderson
contexts through a number of APIs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78258 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-04Check for !isa<Constant> instead of isa<Instruction>. ThisDan Gohman
matches what the comment says, and it avoids spurious BitCast instructions for Argument values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78121 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-03Add a new Constant::getIntegerValue helper function, and convert aDan Gohman
few places in InstCombine to use it, to fix problems handling pointer types. This fixes the recent llvm-gcc bootstrap error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78005 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-03Make SimplifyDemandedUseBits generate vector constants where Eli Friedman
appropriate. Patch per report on llvmdev. No testcase because the original report didn't come with a testcase, and I can't come up with a case that actually fails. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77986 91177308-0d34-0410-b5e6-96231b3b80d8
