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
2009-08-18PowerPC inline asm was emitting two output operandsDale Johannesen
for a single "m" constraint; this is wrong because the opcode of a load or store would have to change in parallel. This patch makes it always compute addresses into a register, which is correct but not as efficient as possible. 7144566. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79292 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

support unaligned mem access only for certain types. (Should it be size instead?) ARM v7 supports unaligned access for i16 and i32, some v6 variants support it as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79127 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Refine EarlyClobber assert in register scavenger.Jakob Stoklund Olesen
It is legal for an inline asm operand to use an earlyclobber register if the use operand is tied to the earlyclobber operand. The issue is discussed here: http://gcc.gnu.org/ml/gcc/1999-04n/msg00431.html We should perhaps let only the machine code verifier worry about these finer details. EarlyClobber operands are not really interesting to the scavenger. This fixes PR4528 for the third time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79122 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Don't setCalleeSavedInfoValid() until spills are interted.Jakob Stoklund Olesen
In a naked function, the flag is never set and getPristineRegs() returns an empty list. That means naked functions are able to clobber callee saved registers, but that is the whole point of naked functions. This fixes PR4716. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79096 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Update LocalRewriter::DistanceMap when inserting stack loads.Jakob Stoklund Olesen
In the included test case, a stack load was not included in DistanceMap. That caused TransferDeadness to ignore the instruction, leading to a scavenger assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79090 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-14llvm-mc: Fix bugs where bytes were unintentionally being printed as signed.Daniel Dunbar
- We now print all of 403.gcc cleanly (llvm-mc -> 'as' as diffed to 'as'), minus two 'rep;movsl' instructions (which I missed before). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79031 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-14llvm-mc: When handling a .set, make sure to print subsequent references to theDaniel Dunbar
symbol as the symbol name itself, not the expression it was defined to. These have different semantics due to the quirky .set behavior (which absolutizes an expression that would otherwise be treated as a relocation). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79025 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-14Update llvm-mc / MCAsmStreamer to print the instruction using the actual targetDaniel Dunbar
specific printer (this only works on x86, for now). - This makes it possible to do some correctness checking of the parsing and matching, since we can compare the results of 'as' on the original input, to those of 'as' on the output from llvm-mc. - In theory, we could now have an easy ATT -> Intel syntax converter. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78986 91177308-0d34-0410-b5e6-96231b3b80d8
