Chris Lattner 3875195865 Remove AllowInverse: it leaks memory and is not the right
abstraction for CommandLine.

Daniel Dunbar 4abd56677d Add llvm::Triple class for abstracting access to target triples.
- The code is silly, I'm just amusing myself. Rewrite to be efficient
   if you like. :)

Also, if you wish to debate the proper names of the triple components
I'm all ears.

Dan Gohman cff6953c45 Use CHAR_BIT instead of hard-coding 8 in several places where it
is appropriate. This helps visually differentiate host-oriented
calculations from target-oriented calculations.

Dale Johannesen 93eefa0043 Fix internal representation of fp80 to be the
same as a normal i80 {low64, high16} rather
than its own {high64, low16}.  A depressing number
of places know about this; I think I got them all.
Bitcode readers and writers convert back to the old
form to avoid breaking compatibility.

Dan Gohman 4f2fea1a21 Now that errs() is properly non-buffered, there's no need to
explicitly flush it.

Daniel Dunbar 437b8a5ccc Add BUILTIN_EXPECT Support/Compiler macro.
- Use for exceptional buffer conditions in raw_ostream:write to shave
   off a cycle or two.

 - Please rename if you have a better one.

llvm-svn: 67103
2009-03-17 21:15:18 +00:00
Daniel Dunbar 64fa3860ed raw_ostream: Put all exceptional conditions in raw_ostream::write
under a single branch.

Also, add a FIXME for formatted output.

llvm-svn: 67069
2009-03-17 01:36:56 +00:00
Daniel Dunbar 2d603dae2c raw_ostream: Rework implementation of unbuffered streams so outputting
a single character requires only one branch to follow slow path.
 - Never use a buffer when writing on an unbuffered stream.

 - Move default buffer size to header.

llvm-svn: 67066
2009-03-17 01:13:35 +00:00
Daniel Dunbar db7a36cdac raw_ostream: Replace flush_impl with write_impl, which takes data to
write as arguments.
 - Add raw_ostream::GetNumBytesInBuffer.
 - Privatize buffer pointers.
 - Get rid of slow and unnecessary code for writing out large strings.

llvm-svn: 67060
2009-03-16 23:29:31 +00:00
Daniel Dunbar d24535fe3c raw_ostream: Lift out flush_nonempty.
- Flush a known non-empty buffers; enforces the interface to
   flush_impl and kills off HandleFlush (which I saw no reason to be
   an inline method, Chris?).

 - Clarify invariant that flush_impl is only called with OutBufCur >
   OutBufStart.

 - This also cleary collects all places where we have to deal with the
   buffer possibly not existing.

 - A few more comments and fixing the unbuffered behavior remain in
   this commit sequence.

it is easy.

2009-03-16 22:08:44 +00:00
Daniel Dunbar 7a9bb9eeec Add slow path for single character write, and use exclusively for
single characters writes outside of the fast path in raw_ostream.h

Stuart Hastings 7440952c01 Fix a hashing bug in APInt. A certain pathological testcase (too
large for the testsuite) took over six minutes to compile on my Mac.
The patched LLVM-GCC compiles that testcase in three seconds (GCC
takes less than one second).  This hash function is more complex
(about 35 instructions on x86) than what Chris wanted, but I expect it
will be well-behaved with arbitrary inputs.

Thank you to everyone who responded to my previous request for advice.

Chris Lattner 0bf186906b Eliminate a 9640 byte static mutable initialized data item by moving it
to the stack.  This shrinks all llvm tools by 9k, and improves reentrancy.

Chris Lattner 8d0fe8cd90 Daniel wanted the stack printed upside down. Perhaps he
feels a kinship to machine stacks that grow down.  Now we get
stuff like this:

Stack dump:

Devang Patel 4d20395a5f The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.
Add support for two additional DWARF attributes to encode Objective-C runtime version number.

Cedric Venet d1e179d992 Unbreak the build on win32.
Cleanup some warning.

Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync.

Only tested with VS2008. hope it does not break anything. feel free to revert.

Mike Stump b92f839f9c Improve -fno-opt style option processing to not require an extra
option to make the -fno- form on the option.  We also document the new
form in the CommandLine documentation.

Torok Edwin ec39eb8519 APInt's countLeadingOnes() was broken for negative i128 values,
causing assertion failures in getSExtValue().
Fix it by making highWordBits actually contain what its name says,
and add some more unit-tests for APInt.
This fixes PR3419.

Devang Patel ccfacfff9a Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, DW_AT_APPLE_flags.
DW_AT_APPLE_optimized flag is set when a compile_unit is optimized. The debugger takes advantage of this information some way.

DW_AT_APPLE_flags encodes command line options when certain env. variable is set. This is used by build engineers to track various gcc command lines used by by  a project, irrespective of whether the project used makefile, Xcode or something else.

llvm-gcc patch is next.

Dale Johannesen 1f86498f93 Do not use host floating point types when emitting
ASCII IR; loading and storing these can change the
bits of NaNs on some hosts.  Remove or add warnings
at a few other places using host floating point;
this is a bad thing to do in general.
