* mcize lcomm, simplify .comm, extend both to support 64-bit sizes.Chris Lattner2010-01-231-2/+2
| | | | llvm-svn: 94299
* resolve a fixme: the "nonexecutable stack directive" is actuallyChris Lattner2010-01-231-5/+2
| | | | | | | | | 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. llvm-svn: 94298
* remove a dead call.Chris Lattner2010-01-231-4/+0
| | | | llvm-svn: 94297
* mcize visibility directives.Chris Lattner2010-01-232-10/+17
| | | | llvm-svn: 94295
* move the various directive enums out of the MCStreamer classChris Lattner2010-01-232-16/+16
| | | | | | into a new MCDirectives.h file. llvm-svn: 94294
* Change constantexpr global variable initializers to convert the constantsChris Lattner2010-01-231-116/+71
| | | | | | | to MCExpr then emit them through MCStreamer with EmitValue. I think all global variable initializers are now going through mcstreamer. llvm-svn: 94293
* mcstreamerize .no_dead_strip and .reference for static ctors/dtors.Chris Lattner2010-01-233-21/+26
| | | | llvm-svn: 94290
* mcize jump table and constant pool entry labels, .local on elf,Chris Lattner2010-01-231-29/+45
| | | | | | and some .weak directives. llvm-svn: 94284
* emit .ascii and .asciz through MCStreamer.Chris Lattner2010-01-231-34/+12
| | | | llvm-svn: 94282
* remove one form of EmitString, just use EmitBytes instead. We mustChris Lattner2010-01-234-40/+27
| | | | | | | be careful to add a \0 at the end though, because EmitString didn't do this. llvm-svn: 94277
* teach MCAsmStreamer::EmitBytes to use .ascii and .ascizChris Lattner2010-01-231-1/+1
| | | | llvm-svn: 94259
* Enable pre-regalloc scheduling load clustering by default.Evan Cheng2010-01-221-7/+1
| | | | llvm-svn: 94255
* move "EOL" from asmprinter to dwarfprinter. It should eventuallyChris Lattner2010-01-225-117/+117
| | | | | | be completely eliminated, but today is not that day. llvm-svn: 94253
* remove uses of EOL.Chris Lattner2010-01-221-6/+2
| | | | llvm-svn: 94252
* add a new EmitCFAByte method and use it.Chris Lattner2010-01-222-14/+23
| | | | llvm-svn: 94251
* move uleb printing from asmprinter to dwarfprinter, mcize,Chris Lattner2010-01-227-124/+83
| | | | | | cleanup and eliminate a bunch more uses of "EOL". llvm-svn: 94250
* move sleb printing out of asmprinter into dwarf printer, make clientsChris Lattner2010-01-226-48/+45
| | | | | | handle the comment better, MCize the non-.sleb case. llvm-svn: 94244
* Remove MetadataBase class because it is not adding significant value.Devang Patel2010-01-221-2/+1
| | | | llvm-svn: 94243
* Ignore DEBUG_VALUE when building live intervals;Dale Johannesen2010-01-222-4/+11
| | | | | | | this makes the code work transparently the same whether they're there or not. llvm-svn: 94240
* add a new DwarfPrinter::EmitEncodingByte method which handlesChris Lattner2010-01-224-66/+59
| | | | | | | | | | | | | | 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 ... llvm-svn: 94239
* rename the dwarf class to DwarfPrinter. This matches the filenameChris Lattner2010-01-228-50/+52
| | | | | | and much more accurately describes what it is all about. llvm-svn: 94233
* fix indentationChris Lattner2010-01-221-128/+117
| | | | llvm-svn: 94232
* inline away the trivial AsmPrinter::EOL() method.Chris Lattner2010-01-227-47/+35
| | | | llvm-svn: 94230
* inline AsmPrinter::PrintHex into its two trivial callers.Chris Lattner2010-01-221-9/+4
| | | | llvm-svn: 94228
* change this to be a static function instead of a method on asmprinter.Chris Lattner2010-01-221-66/+68
| | | | llvm-svn: 94227
* make the loop comment printer print out a much better structuredChris Lattner2010-01-221-15/+23
| | | | | | | | | | | | | 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 llvm-svn: 94225
* For blocks that are not loop headers, just print their loop depth and header BB.Chris Lattner2010-01-221-13/+16
| | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 94221
* reenable the label loop comments and switch them to use the formattedChris Lattner2010-01-221-67/+40
| | | | | | | comment emission stuff. I'm going to rewrite this though because the current output doesn't make sense. llvm-svn: 94215
* Convert some more random-comment-printing stuff to use Chris Lattner2010-01-221-33/+30
| | | | | | | AddComment and GetCommentOS. Add a blank line between globals (even in non-verbose mode) to make the assembly more readable. llvm-svn: 94202
* add a new MCAsmStreamer::GetCommentOS method to simplify stuffChris Lattner2010-01-221-6/+2
| | | | | | that doesn't want to use twines. llvm-svn: 94199
* rename addComment -> AddComment for consistency.Chris Lattner2010-01-221-1/+1
| | | | llvm-svn: 94190
* Revert r94066, which was the patch which added a Verifier pass afterDan Gohman2010-01-221-4/+0
| | | | | | | LoopStrengthReduce, as it's causing too much trouble (even with the old LoopStrengthReduce code). llvm-svn: 94172
* Add the ability for MCStreamer to emit comments on the same line as directives.Chris Lattner2010-01-221-2/+5
| | | | | | | | | | | | 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. llvm-svn: 94166
* pass "-fasm-verbose" into createAsmStreamer.Chris Lattner2010-01-221-6/+12
| | | | llvm-svn: 94165
* Stop building RTTI information for *most* llvm libraries. NotableChris Lattner2010-01-223-3/+6
| | | | | | | | | | | missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. llvm-svn: 94164
* Teach pre-regalloc scheduler to schedule loads from nearby addresses. It may ↵Evan Cheng2010-01-222-0/+134
| | | | | | improve cache locality. This is controlled by -cluster-loads for now. llvm-svn: 94148
* Trim unneeded includes.Evan Cheng2010-01-213-3/+0
| | | | llvm-svn: 94105
* back this out for now. Growing Function is not good.Jim Grosbach2010-01-214-20/+2

* Run the verifier after LSR, to help catch use-before-def errors beforeDan Gohman2010-01-211-0/+4

* Make sure that landing pad entries in the EH call site table are in the properJim Grosbach2010-01-214-2/+20

* SjLj EH introduces can introduce an additional edge to a landing pad and padJim Grosbach2010-01-201-0/+13
| | | | | | normalization needs to take this into account. llvm-svn: 94046
* make findDebugLoc a class methodDale Johannesen2010-01-201-9/+11
| | | | llvm-svn: 94032
* When XDEBUG is enabled, check for SelectionDAG cycles at some keyDavid Greene2010-01-201-1/+35
| | | | | | | points. This will help us find future problems like the one described in PR6019. llvm-svn: 94019
* don't send null pointers through the constantexpr codepath unneededly.Chris Lattner2010-01-201-0/+6

* eliminate some uses of AsmPrinter::EmitIntXXXChris Lattner2010-01-203-20/+19
| | | | llvm-svn: 93996
* inline and radically simplify printDataDirective. It will eventuallyChris Lattner2010-01-201-45/+18

* emit basic block labels with mcstreamer.Chris Lattner2010-01-201-8/+4
| | | | llvm-svn: 93993
* emit integer and fp zeros as (e.g.) .byte 0 instead of .space 1,Chris Lattner2010-01-201-15/+12

* signficant cleanups to EmitGlobalConstant (including streamerization Chris Lattner2010-01-201-103/+67
| | | | | | | | of int initializers), change some methods to be static functions, use raw_ostream::write_hex instead of a smallstring dance with APValue::toStringUnsigned(S, 16). llvm-svn: 93991
* switch ConstantFP emission to use MCStreamer, significantly Chris Lattner2010-01-201-34/+18
