2010-01-25prep work to support a future where getJumpTableInfo will returnChris Lattner
a null pointer for functions with no jump tables. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94469 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-25rename MAI::PICJumpTableDirective to MAI::GPRel32Directive toChris Lattner
make it clear what it is, instead of how it is used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94448 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25pull the non-pic jump table case out of printPICJumpTableEntryChris Lattner
and MCize the non-pic case. Now printPICJumpTableEntry really is just about printing PIC entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94446 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-25sink an arm specific method out of asmprinter into the ARMAsmPrinter andChris Lattner
rename it to avoid shadowing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94440 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25mcstreamerize .file and .file. This also fixes an issue where theChris Lattner
normal form of .file would fail if the filename had a weird character in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94437 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-24fix some issues where we weren't emitting enough newlines.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94370 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-24when emitting DIEs, emit the comment on the same line as the directive.Chris Lattner
This fixes FrontendObjC/2009-11-30-Objc-ID.m git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94369 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-24It seems better to scalarize vectors of size 1 instead of widening them.Mon P Wang
Add support to widen SETCC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94342 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-24Improved widening loads by adding support for wider loads ifMon P Wang
the alignment allows. Fixed a bug where we didn't use a vector load/store for PR5626. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94338 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23Remove the '-disable-scheduling' flag and replace it with the 'source' option ofBill Wendling
the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also, keep track of the SDNode ordering by default. Eventually, we would like to make this ordering a way to break a "tie" in the scheduler. However, doing that now breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94308 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23mcize lcomm, simplify .comm, extend both to support 64-bit sizes.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94299 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23resolve a fixme: the "nonexecutable stack directive" is actuallyChris Lattner
a .section. Switch to it with SwitchSection. However, I think that this directive should be safe on any ELF target. If so, we should hoist it up out of the X86 and SystemZ targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94298 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-23move the various directive enums out of the MCStreamer classChris Lattner
into a new MCDirectives.h file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94294 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23Change constantexpr global variable initializers to convert the constantsChris Lattner
to MCExpr then emit them through MCStreamer with EmitValue. I think all global variable initializers are now going through mcstreamer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94293 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23mcstreamerize .no_dead_strip and .reference for static ctors/dtors.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94290 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23mcize jump table and constant pool entry labels, .local on elf,Chris Lattner
and some .weak directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94284 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23emit .ascii and .asciz through MCStreamer.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94282 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23remove one form of EmitString, just use EmitBytes instead. We mustChris Lattner
be careful to add a \0 at the end though, because EmitString didn't do this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94277 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22move "EOL" from asmprinter to dwarfprinter. It should eventuallyChris Lattner
be completely eliminated, but today is not that day. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94253 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94252 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22add a new EmitCFAByte method and use it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94251 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22move uleb printing from asmprinter to dwarfprinter, mcize,Chris Lattner
cleanup and eliminate a bunch more uses of "EOL". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94250 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22move sleb printing out of asmprinter into dwarf printer, make clientsChris Lattner
handle the comment better, MCize the non-.sleb case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94244 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94243 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22Ignore DEBUG_VALUE when building live intervals;Dale Johannesen
this makes the code work transparently the same whether they're there or not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94240 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22add a new DwarfPrinter::EmitEncodingByte method which handlesChris Lattner
pretty printing encoding comments and eliminates redundancy on the client side. We now get pretty dwarf like this again: .byte 255 ## @LPStart Encoding = omit .byte 0 ## @TType Encoding = absptr .byte 0x28 ## @TType base offset .byte 3 ## Call site Encoding = udata4 .byte 0x1a ## Call site table size ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94239 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22rename the dwarf class to DwarfPrinter. This matches the filenameChris Lattner
and much more accurately describes what it is all about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94233 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22fix indentationChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94232 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22inline away the trivial AsmPrinter::EOL() method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94230 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22inline AsmPrinter::PrintHex into its two trivial callers.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94228 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22change this to be a static function instead of a method on asmprinter.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94227 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22make the loop comment printer print out a much better structuredChris Lattner
output. An example: .align 4, 0x90 LBB1_5: ## %while.cond3 ## Parent Loop BB1_1 Depth=1 ## => This Loop Header: Depth=2 ## Child Loop BB1_8 Depth 3 ## Child Loop BB1_6 Depth 3 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94225 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22For blocks that are not loop headers, just print their loop depth and header BB.Chris Lattner
For loop headers, print Inner loop along with the other stuff so it doesn't take an extra line. We now get stuff like this: LBB1_4: ## %land.end ## in Loop: Header=BB1_1 Depth=1 notb %al testb $1, %al jne LBB1_8 and: LBB1_6: ## %while.cond7 ## Inner Loop Header: Depth=3 ## Inside Loop BB1_5 Depth 2 ## Inside Loop BB1_1 Depth 1 which still isn't great for loop headers, but is much less verbose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94221 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22reenable the label loop comments and switch them to use the formattedChris Lattner
comment emission stuff. I'm going to rewrite this though because the current output doesn't make sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94215 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22Convert some more random-comment-printing stuff to use Chris Lattner
AddComment and GetCommentOS. Add a blank line between globals (even in non-verbose mode) to make the assembly more readable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94202 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22add a new MCAsmStreamer::GetCommentOS method to simplify stuffChris Lattner
that doesn't want to use twines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94199 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22rename addComment -> AddComment for consistency.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94190 91177308-0d34-0410-b5e6-96231b3b80d8
