whitespace.

Owen Anderson 8e2456c254 Ease contention on this lock by noticing that all writes to the VTs array will 
be of (dynamically) constant values, so races on it are immaterial.  We just need
to ensure that at least one write has completed before return the pointer into it.

With this change, parllc exhibits essentially no overhead on 403.gcc.

llvm-svn: 79698
 2009-08-21 23:30:30 +00:00
Daniel Dunbar 67dfb1de23 llvm-mc: Improve handling of implicit alignment for magic section directives 
(e.g., .objc_message_refs).
 - Just emit a .align when we see the directive; this isn't exactly what 'as'
   does but in practice it should be ok, at least for now. See FIXME.

llvm-svn: 79697

llvm-svn: 79684
 2009-08-21 23:07:38 +00:00
Daniel Dunbar 4abcccb965 llvm-mc: In a .fill directive, still honor .align even if invalid maximum bytes

llvm-svn: 79677
 2009-08-21 22:10:30 +00:00
Bob Wilson ceffeb6abd Rename ARM "lane_cst" operands to "nohash_imm" since they are used for 
several things other than Neon vector lane numbers.  For inline assembly
operands with a "c" print code, check that they really are immediates.

llvm-svn: 79676
 2009-08-21 21:58:55 +00:00
Reid Kleckner 48ca915be9 Fix a bug where the DWARF emitter in the JIT was not initializing alignment 
bytes.  libgcc doesn't seem to mind, but if you pass this DWARF to GDB, it
doesn't like it.  

Also make the JIT memory manager to initialize it's memory to garbage in debug
mode, so that it's easier to find bugs like these in the future.

Daniel Dunbar 3016db39dd llvm-mc: Start MCAssembler and MCMachOStreamer. 
- Together these form the (Mach-O) back end of the assembler.

 - MCAssembler is the actual assembler backend, which is designed to have a
   reasonable API. This will eventually grow to support multiple object file
   implementations, but for now its Mach-O/i386 only.

 - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API,
   e.g. converting the various directives into fragments, managing state like
   the current section, and so on.

 - llvm-mc will use the new backend via '-filetype=obj', which may eventually
   be, but is not yet, since I hear that people like assemblers which actually
   assemble.

 - The only thing that works at the moment is changing sections. For the time
   being I have a Python Mach-O dumping tool in test/scripts so this stuff can
   be easily tested, eventually I expect to replace this with a real LLVM tool.

 - More doxyments to come.

I assume that since this stuff doesn't touch any of the things which are part of
2.6 that it is ok to put this in not so long before the freeze, but if someone
objects let me know, I can pull it.

llvm-svn: 79612
 2009-08-21 09:11:24 +00:00
Daniel Dunbar 9df5f33818 llvm-mc: Various section parsing fixes. 
- Add missing flags for various Objective-C sections.

 - Fix names for [non_]lazy_symbol_pointer (these are misspelled in the manual).

 - .symbol_stub does not have the self modifying code flag set (this appears to
   be wrong in the manual?).

 - Add implicit alignment values; not yet used.

Also, call MCStreamer::Finish at the end of a successful parse.

llvm-svn: 79563
 2009-08-20 19:34:18 +00:00
Sanjiv Gupta 686e9f55dc Implement support for ISRs. 
Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

Dan Gohman c59ba42b0f Fix a bug in the over-index constant folding. When over-indexing an 
array member of a struct, it's possible to land in an arbitrary position
inside that struct, such that attempting to find further getelementptr
indices will fail. In such cases, folding cannot be done.

 2009-08-19 19:41:05 +00:00
Daniel Dunbar 339d0cbdd1 Remove SmallString::append_*int* methods; how many copies of int -> str 
conversion code do we really need?
 - S.append_uint(N) can be replaced with 'raw_svector_ostream(S) << N' which is
   somewhat slower due to the extra set up cost, but still plenty fast
   (especially if the svector set up cost can be amortized).

Daniel Dunbar e813cbaa21 Change raw_svector_ostream to reserve the input buffer if necessary, Ted was 
right.
 - This class turns out to be much more convenient to use if we do this; clients
   can make sure the buffer is always big enough if they care (since our current
   idiom tends to be to use a SmallString<256> for the input to this we should
   generally be avoiding an unnecessary malloc).

Also, add a convenience raw_svector_ostream::str method which flushes the buffer
and returns a StringRef for the vector contents.

Dan Gohman 81ce842ecf Canonicalize indices in a constantexpr GEP. If Indices exceed the 
static extents of the static array type, it causes GlobalOpt and
other passes to be more conservative. This canonicalization also
allows the constant folder to add "inbounds" to GEPs.

Daniel Dunbar b090bf4626 Switch raw_svector_ostream to use the vector as the ostream buffer.

   unnecessary copying from the ostream buffer into the output vector.
