2010-01-26Now that printPICJumpTableSetLabel is not overloaded,Chris Lattner
inline it into its only caller, allowing us to simplify it and hoist bits out of the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94528 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Move getJTISymbol from MachineJumpTableInfo to MachineFunction,Chris Lattner
which is more convenient, and change getPICJumpTableRelocBaseExpr to take a MachineFunction to match. Next, move the X86 code that create a PICBase symbol to X86TargetLowering::getPICBaseSymbol from X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific library. This eliminates a 'gross hack', and allows us to implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now calls it. This in turn allows us to eliminate the X86AsmPrinter::printPICJumpTableSetLabel method, which was the only overload of printPICJumpTableSetLabel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94526 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26add a new MachineJumpTableInfo::getJTISymbol method,Chris Lattner
use it to implement the default TargetLowering::getPICJumpTableRelocBaseExpr git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94523 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26simplify asmprinter: only emit .set directives when entries haveChris Lattner
EK_LabelDifference32 kind and the target has .set support. Simplify X86AsmPrinter::printPICJumpTableSetLabel to make use of recent helpers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94518 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26rename printPICJumpTableEntry -> EmitJumpTableEntry,Chris Lattner
make it private and non-virtual. It handles the non-pic case too, so just use it, simplifying EmitJumpTableInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94517 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26add a new MachineBasicBlock::getSymbol method, replacingChris Lattner
the AsmPrinter::GetMBBSymbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94515 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26make MachineFunction keep track of its ID and make Chris Lattner
MachineFunctionAnalysis dole them out, instead of having AsmPrinter do both. Have the AsmPrinter::SetupMachineFunction method set the 'AsmPrinter::MF' variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94509 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26Add support for target-specific 32-bit custom-lowered Chris Lattner
jump table entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94505 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-26switch jump table entry emission to be based on EntryKindChris Lattner
instead of magic variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94500 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25Rearrange handling of jump tables. Highlights:Chris Lattner
1. MachineJumpTableInfo is now created lazily for a function the first time it actually makes a jump table instead of for every function. 2. The encoding of jump table entries is now described by the MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the TLI::getJumpTableEncoding() hook, instead of by lots of code scattered throughout the compiler that "knows" that jump table entries are always 32-bits in pic mode (for example). 3. The size and alignment of jump table entries is now calculated based on their kind, instead of at machinefunction creation time. Future work includes using the EntryKind in more places in the compiler, eliminating other logic that "knows" the layout of jump tables in various situations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94470 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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94445 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

mcstreamer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94416 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

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

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
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
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
2010-01-22inline 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
2010-01-22Add the ability for MCStreamer to emit comments on the same line as directives.Chris Lattner
Switch over the asm-verbose comment for double values to use it. We now get: _x: .long 343597384 ## double 1.231200e+02 .long 1079953326 For example, note that the comment is on the same line as the .long. Woo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94166 91177308-0d34-0410-b5e6-96231b3b80d8
