* 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

* 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

* 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

* 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

* signficant cleanups to EmitGlobalConstant (including streamerization Chris Lattner2010-01-201-103/+67

* Do not extend extension results beyond the use of a PHI instruction at the ↵Evan Cheng2010-01-191-0/+12

* refactor code to be static functions instead of methods on AsmPrinter.Chris Lattner2010-01-191-47/+39
| | | | | | This fixes some bugs handling address spaces. llvm-svn: 93891
* mcstreamerize AsmPrinter::EmitZeros, at least when emitting to the Chris Lattner2010-01-191-8/+6
| | | | | | default address space. llvm-svn: 93890
* remove MAI::ZeroDirectiveSuffix, which is only used by MASM,Chris Lattner2010-01-191-10/+6

* For aligned load/store instructions, it's only required to know whether aJim Grosbach2010-01-191-70/+0
| | | | | | | | | | | function can support dynamic stack realignment. That's a much easier question to answer at instruction selection stage than whether the function actually will have dynamic alignment prologue. This allows the removal of the stack alignment heuristic pass, and improves code quality for cases where the heuristic would result in dynamic alignment code being generated when it was not strictly necessary. llvm-svn: 93885
* mcstreamer'ize the rest of EmitGlobalVariable that is used on Chris Lattner2010-01-191-6/+8
