2011-07-14Check register class matching instead of width of type matchingEric Christopher
when determining validity of matching constraint. Allow i1 types access to the GR8 reg class for x86. Fixes PR10352 and rdar://9777108 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135180 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Reorganize ARM assembler aliases.Jim Grosbach
Consolidate the individual declarations together for ease of reference. This mirrors the organization in X86, as well, so is good for consistency. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135179 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14DebugLoc's don't hide any interesting types for TypeFinder to find.Chris Lattner

2011-07-14manually copy debugloc over to a new instruction in clone() insteadChris Lattner
of calling getAllMetadata(). This is semantically identical, but doing it this way avoids unpacking the DebugLoc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135173 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Stop the ValueMapper from calling getAllMetadata, which unpacks DebugLoc intoChris Lattner
an MDNode. This saves a bunch of time and memory in the IR linker, e.g. when doing LTO of files with debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135172 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14Update ARM Assembly of LDM/STM.Jim Grosbach
ldm/stm are the cannonical spellings for ldmia/stmia, so use them as such. Update the parsing/encoding tests accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135168 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14The key of a StringMap can contain nul's in it, so having first() returnChris Lattner
const char* doesn't make sense. Have it return StringRef instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135167 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14ARM ISB instruction assembly parsing.Jim Grosbach
The ISB instruction takes an optional operand, just like DMB/DSB. Typically only 'sy' is meaningful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135156 91177308-0d34-0410-b5e6-96231b3b80d8

reference the array passed to them instead of copying it to a std::vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135145 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14[VECTOR-SELECT]Nadav Rotem
During type legalization we often use the SIGN_EXTEND_INREG SDNode. When this SDNode is legalized during the LegalizeVector phase, it is scalarized because non-simple types are automatically marked to be expanded. In this patch we add support for lowering SIGN_EXTEND_INREG manually. This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements' flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135144 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-14Unfortunately several files in MC are badly violating layering rule by usingEvan Cheng
TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are other cases of violations, but this is probably the worst. This patch is but one small step towards fixing this. 500 more steps to go. :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135131 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Reapply r135121 with a fixed copy constructor.Jakob Stoklund Olesen
Original commit message: Count references to interference cache entries. Each InterferenceCache::Cursor instance references a cache entry. A non-zero reference count guarantees that the entry won't be reused for a new register. This makes it possible to have multiple live cursors examining interference for different physregs. The total number of live cursors into a cache must be kept below InterferenceCache::getMaxCursors(). Code generation should be unaffected by this change, and it doesn't seem to affect the cache replacement strategy either. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135130 91177308-0d34-0410-b5e6-96231b3b80d8
