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.

Erick Tryzelaar da666c801c Add support for including '+' in APFloat strings, more asserts,

 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 05046085b6 Fix an x86 code size regression: prefer RIP-relative addressing

Dan Gohman 2de532c132 Clarify a few things in the inbounds description. 
Describing inbounds in terms of infinitely precise arithmetic prohibits

llvm-svn: 79491

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 20:27:57 +00:00
Daniel Dunbar 8b0b11582d Switch to SmallString::str from SmallString::c_str, and remove 
SmallString::c_str.

llvm-svn: 79454
 2009-08-19 19:58:19 +00:00
Daniel Dunbar 03d4b9eac4 Add SmallString::str (which returns a StringRef); this is more efficient than 
c_str().

llvm-svn: 79453

Benjamin Kramer 902ccf22b4 Remove SmallString::append_*int* unit tests. 
llvm-svn: 79451
 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).

llvm-svn: 79450
 2009-08-19 19:28:18 +00:00
Daniel Dunbar 948f82b8e4 Change ValueSymbolTable to use raw_svector_ostream for string concatenation.

Bill Wendling 6c528bc7ae Make this test platform neutral. 
llvm-svn: 79447
 2009-08-19 18:51:45 +00:00
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.

llvm-svn: 79442
 2009-08-19 18:22:18 +00:00
Dan Gohman 5d5bc6d000 Use hasDefinitiveInitializer() instead of testing the same thing 
by hand, and fix a few places that were using hasInitializer() that
appear to depend on the initializer value.

llvm-svn: 79441
 2009-08-19 18:20:44 +00:00
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.

llvm-svn: 79440
 2009-08-19 18:18:36 +00:00
Dan Gohman ac33a9061d Add an x86 peep that narrows TEST instructions to forms that use

sqlite3, for example.

 2009-08-19 17:58:52 +00:00
Daniel Dunbar b090bf4626 Switch raw_svector_ostream to use the vector as the ostream buffer. 
- This avoids unnecessary malloc/free overhead in the common case, and
   unnecessary copying from the ostream buffer into the output vector.

llvm-svn: 79434
 2009-08-19 17:54:29 +00:00
Daniel Dunbar 825e955e40 Add SmallVector::{capacity,set_size}. 
- These allow clients to make use of the extra elements in the vector which
   have already been allocated, without requiring them to be value initialized.

Erick Tryzelaar 9eb4a5f418 Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType. 
gcc-4.4 was optimizing away comparisons against SimpleValueType when
it was compared to a value larger than the largest value in the enum.
This patch works around it by adding one extra item to the enum so
that these tests will now be valid.

Daniel Dunbar 17a6fd2299 raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation. 
- Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

Jakob Stoklund Olesen 36d747745e Simplify RegScavenger::FindUnusedReg. 
- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

Dan Gohman 23f90c1d3a Fix a bug in raw_ostream::write(char) introduced by the change to

declined buffering.
