2011-12-08Drop the HasInlineAsm flag.Jakob Stoklund Olesen
It is not used any more. We are tracking inline assembly misalignments directly through the BBInfo.Unalign and KnownBits fields. A simple conservative size estimate is not good enough since it can cause alignment padding to be underestimated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146124 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146119 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-08Don't include alignment padding in BBInfo.Size.Jakob Stoklund Olesen
Compute alignment padding before and after basic blocks dynamically. Heed basic block alignment. This simplifies bookkeeping because we don't have to constantly add and remove padding from BBInfo.Size. It also makes it possible to track the extra known alignment bits we get after a tBR_JTr terminator and when entering an aligned basic block. This makes the ARMConstantIslandPass aware of aligned basic blocks. It is tricky to model block alignment correctly when dealing with inline assembly and tBR_JTr instructions that have variable size. If inline assembly turns out to be smaller than expected, that may cause following alignment padding to be larger than expected. This could cause constant pool entries to move out of range. To avoid that problem, we use the worst case alignment padding following inline assembly. This may cause slightly suboptimal constant island placement in aligned basic blocks following inline assembly. Normal functions should be unaffected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146118 91177308-0d34-0410-b5e6-96231b3b80d8

When the file isn't being built with subsections-via-symbols, symbol differences involving non-local symbols can be resolved more aggressively. Needed for gas compatibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146054 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-07Add bundle aware API for querying instruction properties and switch the codeEvan Cheng
generator to it. For non-bundle instructions, these behave exactly the same as the MC layer API. For properties like mayLoad / mayStore, look into the bundle and if any of the bundled instructions has the property it would return true. For properties like isPredicable, only return true if *all* of the bundled instructions have the property. For properties like canFoldAsLoad, isCompare, conservatively return false for bundles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146026 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-07Eliminate delta argument from AdjustBBOffsetsAfter.Jakob Stoklund Olesen
The block offset can be computed from the previous block. That is more robust than keeping track of a delta. Eliminate one redundant AdjustBBOffsetsAfter call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146018 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06Revert r145971: "Use conservative size estimate for tBR_JTr."Jakob Stoklund Olesen

Taught MachineBasicBlock methods about bundled MIs git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145975 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Use conservative size estimate for tBR_JTr.Jakob Stoklund Olesen
This pseudo-instruction contains a .align directive in its expansion, so the total size may vary by 2 bytes. It is too difficult to accurately keep track of this alignment directive, just use the worst-case size instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145971 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Remove alignment from deserted constant islands.Jakob Stoklund Olesen
ARMConstantIslandPass may sometimes leave empty constant islands behind (it really shouldn't). Remove the alignment from the empty islands so the size calculations are still correct. This should fix the many Thumb1 assembler errors in the nightly test suite. The reduced test case for this problem is way too big. That is to be expected for ARMConstantIslandPass bugs. <rdar://problem/10534709> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145970 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the alias to encode 'mul r5, r6' as if it were 'mul r5, r6, r5' so we match gas. rdar://10532439 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145922 91177308-0d34-0410-b5e6-96231b3b80d8

rdar://10528060 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145891 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Align ARM constant pool islands via their basic block.Jakob Stoklund Olesen
Previously, all ARM::CONSTPOOL_ENTRY instructions had a hardwired alignment of 4 bytes emitted by ARMAsmPrinter. Now the same alignment is set on the basic block. This is in preparation of supporting ARM constant pool islands with different alignments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145890 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06Move target-specific logic out of generic MCAssembler.Jim Grosbach
Whether a fixup needs relaxation for the associated instruction is a target-specific function, as the FIXME indicated. Create a hook for that and use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145881 91177308-0d34-0410-b5e6-96231b3b80d8
