Dan Gohman aa92dc1e61 LLVM currently represents floating-point negation as -0.0 - x. Fix 
FastISel to recognize this pattern and emit a floating-point
negation using xor.

Bob Wilson 33b408a10f Fix pr4843: When an instruction has multiple destination registers that are 
tied to different source registers, the TwoAddressInstructionPass needs to
be smarter.  Change it to check before replacing a source register whether
that source register is tied to a different destination register, and if so,
defer handling it until a subsequent iteration.

Jim Grosbach f09e8d5497 SJLJ is arm/darwin only for now. force the triple for the test 
llvm-svn: 80651
 2009-09-01 02:34:49 +00:00
Jim Grosbach 20eac92d88 Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

Anton Korobeynikov eab572a8ff EXTRACT_VECTOR_ELEMENT can have result type different from element type. 
Remove the assertion and generalize the code for ARM NEON stuff.

Dan Gohman ca73326f56 CMOV_GR8 clobbers EFLAGS when its expansion involves an xor to set 
a register to 0. This fixes PR4814.

Anton Korobeynikov 205cac837f scalar_to_vector is fully legal now (implemented as subreg accesses) 
llvm-svn: 80249
 2009-08-27 16:04:47 +00:00
Anton Korobeynikov d0b0262edf Ok, sometimes it's profitable to turn scalar_to_vector stuff into subreg access. 
Add a testcase.

Dan Gohman 7f0ca9a34c X86FastISel support for loading and storing values of type i1. 
llvm-svn: 80186
 2009-08-27 00:31:47 +00:00
Dan Gohman f1abb5511b Expand i8 selects into control flow instead of 16-bit conditional 
moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.

Dan Gohman 6c23fa2442 Don't use INSERT_SUBREG to model anyext operations on x86-64, as it 
leads to partial-register definitions. To help avoid redundant
zero-extensions, also teach the h-register matching patterns that
use movzbl to match anyext as well as zext.

Daniel Dunbar 9cc4970ed3 Switch abi-isel.ll to FileCheck; it's not much faster, but it now tests a lot 
more and is much nicer to the OS.
 - Dan, please check. If there are parts of the test you think I should strip
   out so it doesn't cause random failures let me know (there are still some PIC
   label numbers in it, for example).

Scott Michel ec89f0c41a - Remove SelectSEXTi128 from SPUISelDAGToDAG.cpp, evidently, this is redundant 
code, according to Anton (I'm not totally convinced, but we can always
  resurrect patches if we need to do so.)
- Start moving CellSPU's tests to prefer FileCheck.
