Bruno Cardoso Lopes c773141e66 *try* to use a better name to describe how common symbols are marked on the elf object file.

Argyrios Kyrtzidis ac74c4c2a1 Revert r78424. 
In order for the changes in r78424 to work properly, cast_retty<X,Y> should return an object instead of a reference, and it's not clear that this approach has real advantages.

Erick Tryzelaar 330b1b4cd8 A couple IRBuilder functions were still using getGlobalContext().

Daniel Dunbar 80d484e7cc Update llvm-mc / MCAsmStreamer to print the instruction using the actual target 
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

 2009-08-14 03:48:55 +00:00
Daniel Dunbar 50327c561b Add virtual printMCInst method to AsmPrinter, as a quick way to expose the API 
to print one instruction.

Daniel Dunbar 9abdc6cc3c TargetRegistry: Change AsmPrinter constructor to be typed as returning an 
AsmPrinter instance (instead of just a FunctionPass)

llvm-svn: 78962
 2009-08-13 23:48:47 +00:00
Daniel Dunbar aba5fb8c9a llvm-mc: Add dummy MCStreamer implementation, (eventually) for use in profiling. 
- Currently unused.

 - A few other random comment fixes lumped in.

Bruno Cardoso Lopes 62e6a8bbe6 Remove HasCrazyBSS and add a flag in TAI to indicate that '.section' 
must be emitted for PowerPC-Linux '.bss' section

Owen Anderson a42ac6953b Actually privatize a IntegerTypes, and fix a few bugs exposed by this. 
llvm-svn: 78955
 2009-08-13 23:27:32 +00:00
Dan Gohman d57cbfc7d8 Make formatted_raw_ostream restore the buffer settings of the 
underlying stream when it is finished, so that clients don't
have to do this manually.

llvm-svn: 78952
 2009-08-13 23:16:59 +00:00
Owen Anderson 55f1c09e31 Push LLVMContexts through the IntegerType APIs.

Bruno Cardoso Lopes df743ae603 Add a method to return if the ELF section contains only common symbols! 
llvm-svn: 78937
 2009-08-13 21:08:56 +00:00
Dan Gohman e6e417149f Add unimplemented destructor declarations to hopefully address 
compiler warnings on windows (PR4714).

 2009-08-13 20:43:13 +00:00
Daniel Dunbar 95f58463e5 TargetRegistry: Reorganize AsmPrinter construction so that clients pass in the 
TargetAsmInfo. This eliminates a dependency on TargetMachine.h from
TargetRegistry.h, which technically was a layering violation.
 - Clients probably can only sensibly pass in the same TargetAsmInfo as the
   TargetMachine has, but there are only limited clients of this API.

llvm-svn: 78928
 2009-08-13 19:38:51 +00:00
Dan Gohman 854ea3c580 Set raw_os_ostream, raw_string_ostream, and raw_svector_ostream to be 
unbuffered. std::ostream does its own buffering, and std::string and
SmallVector both have allocation strategies intended to handle frequent
appending.

llvm-svn: 78924
 2009-08-13 17:41:40 +00:00
Dan Gohman 84487b98a5 Add support to raw_ostream for sizing the buffer according to the 
needs of the underlying output mechanism. raw_fd_ostream now uses
st_blksize from fstat to determine a buffer size.

llvm-svn: 78923
 2009-08-13 17:27:29 +00:00
Dan Gohman f0b93441a4 Make raw_ostream non-copyable.

Daniel Dunbar 86c065dd68 Revert 78892 and 78895, these break generating working executables on 
x86_64-apple-darwin10.

Dan Gohman 54401d4174 Move SetBufferSize and SetUnbuffered out of line. 
llvm-svn: 78909
 2009-08-13 15:58:55 +00:00
Dan Gohman 52022c2373 Fix the buffer handling logic so that write_impl is always called with 
a full buffer, rather than often being called with a
slightly-less-than-full buffer.

llvm-svn: 78907
 2009-08-13 15:44:52 +00:00
Jakob Stoklund Olesen 33733c0342 Fix the N>=64 case in the isInt<> and isUint<> templates. 
llvm-svn: 78899
 2009-08-13 06:24:02 +00:00
Chris Lattner eb68198145 fix a minor fixme. When building with SL and later tools, the ".eh" symbols 
don't need to be exported from the .o files.

llvm-svn: 78892
 2009-08-13 05:30:22 +00:00
Bruno Cardoso Lopes 607cd3b63a Change MCSectionELF to represent a section semantically instead of 
syntactically as a string, very similiar to what Chris did with MachO.
The parsing support and validation is not introduced yet.

llvm-svn: 78890
 2009-08-13 05:07:35 +00:00
Daniel Dunbar 3a1efd11bb Convert APint::{fromString,APInt,getBitsNeeded} to use StringRef. 
- Patch by Erick Tryzelaar, with some edits (and a bug fix) from me.

llvm-svn: 78885
 2009-08-13 02:33:34 +00:00
Daniel Dunbar d0cfa88785 Add StringRef::front (with some small tweaks while I was in the area). 
- Patch by Erick Tryzelaar

Chris Lattner 04b4700ebc sink uniquing of sections out of MCContext into the ELF and PECOFF TLOF implementations. 
MCContext no longer maintains a string -> section map.

llvm-svn: 78874
 2009-08-13 00:37:15 +00:00
Chris Lattner b691316838 add some comments: MCContext owns the MCSections, but it bump pointer allocates 
them, so it doesn't have to explicitly free them.

llvm-svn: 78870
 2009-08-13 00:21:53 +00:00
Chris Lattner c0741ebb3a reject invalid code like: 
int x __attribute__((section("_foo, _bar"))) = 4;
int y __attribute__((section("_foo, _bar, 4byte_literals"))) = 1;

llvm-svn: 78867
 2009-08-13 00:05:07 +00:00

Jim Grosbach b6cac314aa Mark the callsite intrinsic such that the opimizers know it's not dead. 
llvm-svn: 78856
 2009-08-12 23:03:43 +00:00
Bob Wilson f7e587fd53 Add a new "SDTCisVec" SDTypeConstraint. This complements the vAny type. 
There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained.  It is easy to add this now and should help
catch errors in the future.

Dan Gohman 1432ef864e This void is implicit in C++.

 2009-08-12 22:10:57 +00:00
Dan Gohman 9099b179f2 Add a GetBufferSize() member to raw_ostream and use it to 
simplify some formatted_raw_ostream code.

llvm-svn: 78836
 2009-08-12 20:52:45 +00:00
David Goodwin b369ee4c48 Enhance the InstrStage object to enable the specification of an Itinerary with overlapping stages. The default is to maintain the current behavior that the "next" stage immediately follows the previous one. 
llvm-svn: 78827
 2009-08-12 18:31:53 +00:00
Dan Gohman 5476cfdb15 Remove a bunch more now-unnecessary Context arguments.

Chris Lattner 9a6cf91261 Change TargetAsmInfo to be constructed via TargetRegistry from a Target+Triple 
pair instead of from a virtual method on TargetMachine.  This cuts the final
ties of TargetAsmInfo to TargetMachine, meaning that MC can now use 
TargetAsmInfo.

llvm-svn: 78802
 2009-08-12 07:22:17 +00:00
Chris Lattner e0971bc29f add support for mingw64 target triples. 
llvm-svn: 78797

Jakob Stoklund Olesen ee01029811 Move immediate constant predicate templates from the Blackfin target to MathExtras.h 
llvm-svn: 78793
 2009-08-12 06:22:07 +00:00
Chris Lattner 553c9f35a7 add a couple of helpers to the Triple class for decoding 
the darwin version string.  This should help consolidate
the variety of weird functions we have scattered around the
codebase that do stuff like this.
