Reid Spencer ae4675226e Make sure these tests pass for the right reasons (verifier error, rather than 
failure to assemble).

Devang Patel 561b0c29a3 Update dominator info for the middle blocks created while spliting 
exit edge to preserve LCSSA.

Dan Gohman 54ec4bfa5f Change the x86 assembly output to use tab characters to separate the 
mnemonics from their operands instead of single spaces. This makes the
assembly output a little more consistent with various other compilers
(f.e. GCC), and slightly easier to read. Also, update the regression
tests accordingly.

Reid Spencer d45d07ac72 For PR1553: 
Make the AsmParser auto-upgrade the old zext and sext
keywords for parameter attributes and handle the 
end-of-line ambiguity.

Reid Spencer 7717ff5368 Be explicit about which level of optimization is being asked for. The -O option 
is equivalent to -O1.

Nick Lewycky 62989d6775 Make this explictly signed. Fixes PR1571. 
llvm-svn: 40569
 2007-07-28 16:43:10 +00:00
Dan Gohman 4788552deb Re-apply 40504, but with a fix for the segfault it caused in oggenc: 
Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.

llvm-svn: 40555
 2007-07-27 17:16:43 +00:00
Evan Cheng 931de40afa Reverting 40504 for now. It's breaking oggenc.
