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.

Daniel Dunbar d81866827c Add temporary hack to teach LLVM to reconfigure itself to pick up the new PIC16 
AsmPrinter (in AsmPrinters.def).

 2009-08-13 16:20:04 +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.

 2009-08-13 15:44:52 +00:00
Dan Gohman 8061d9e23f Fix a 4x slowdown in llc -asm-verbose caused by the use of 
WriteAsOperand in more places.

Now that more things are using WriteAsOperand, its behavior of
constructing a TypePrinting object and populating it with strings for all
the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

Chris Lattner 68535f7603 reintroduce support for Mips "small" section handling. This is 
implemented somewhat differently than before, but it should have
the same functionality and the previous testcase passes again.

Mon P Wang a95379d165 When InstCombine simplifies a load -> extract element to gep -> load, place 
the new load by the old load instead of by the extract element because
a store could have occurred between the load and extract element.

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.

Dan Gohman b4583b1b36 Change the indentation for LLVM Assembly files from 1 tab to 2 spaces. 
This is vaguely consistent with LLVM's own source code, but more
importantly it lets more lines stay within 80 columns.
