* Fix build on Linux.Mikhail Glushenkov2009-04-021-0/+1
| | | | llvm-svn: 68269
* Add llvm::Triple class for abstracting access to target triples.Daniel Dunbar2009-04-011-0/+183
| | | | | | | | | | - 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. llvm-svn: 68252
* Use CHAR_BIT instead of hard-coding 8 in several places where itDan Gohman2009-04-011-3/+3
| | | | | | | is appropriate. This helps visually differentiate host-oriented calculations from target-oriented calculations. llvm-svn: 68227
* * Fixed spelling of `invertible'Misha Brukman2009-04-011-2/+2
| | | | | | * Simplified if statement llvm-svn: 68163

* Fix internal representation of fp80 to be theDale Johannesen2009-03-231-8/+6
| | | | | | | | | | 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. llvm-svn: 67562
* Now that errs() is properly non-buffered, there's no need toDan Gohman2009-03-231-1/+0
| | | | | | explicitly flush it. llvm-svn: 67526
* Fix comment typo.Duncan Sands2009-03-191-1/+1
| | | | llvm-svn: 67302
* Add BUILTIN_EXPECT Support/Compiler macro.Daniel Dunbar2009-03-171-1/+2
| | | | | | | | | - 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
* raw_ostream: Put all exceptional conditions in raw_ostream::writeDaniel Dunbar2009-03-171-18/+30
| | | | | | | | under a single branch. Also, add a FIXME for formatted output. llvm-svn: 67069
* raw_ostream: Rework implementation of unbuffered streams so outputtingDaniel Dunbar2009-03-171-4/+12
| | | | | | | | | 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
* raw_ostream: Replace flush_impl with write_impl, which takes data toDaniel Dunbar2009-03-161-32/+15
| | | | | | | | | 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
* raw_ostream: Lift out flush_nonempty.Daniel Dunbar2009-03-161-20/+21
| | | | | | | | | | | | | | | | | - 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. llvm-svn: 67057
* Make raw_ostream::operator<<(const void *) fast; it doesn't matter butDaniel Dunbar2009-03-161-2/+19
| | | | | | it is easy. llvm-svn: 67054
* Add slow path for single character write, and use exclusively forDaniel Dunbar2009-03-161-8/+8
| | | | | | single characters writes outside of the fast path in raw_ostream.h llvm-svn: 67053
* Fix a hashing bug in APInt. A certain pathological testcase (tooStuart Hastings2009-03-131-7/+85
| | | | | | | | | | | | 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. llvm-svn: 66962
* just initialize the first element, we don't need to set the rest to zeros.Chris Lattner2009-03-131-3/+3
| | | | llvm-svn: 66850
* Eliminate a 9640 byte static mutable initialized data item by moving itChris Lattner2009-03-131-2/+2
| | | | | | to the stack. This shrinks all llvm tools by 9k, and improves reentrancy. llvm-svn: 66847
* static functions don't need an anonymous namespace.Chris Lattner2009-03-121-373/+371
| | | | llvm-svn: 66845
* PR3478: raw_ostream should not buffer stderrDaniel Dunbar2009-03-101-1/+5
| | | | | | | - Add unbuffered flag to raw_ostream, forwarded by raw_fd_ostream and used by raw_stderr_ostream. llvm-svn: 66545
* Use c_str() to force the string to be nul-terminated.Dan Gohman2009-03-061-1/+1
| | | | llvm-svn: 66279
* on apple systems, integrate nicely with crash reporter.Chris Lattner2009-03-061-4/+34

* add some helper classes for building light-weight symbolic stack tracesChris Lattner2009-03-041-0/+69
| | | | | | that get printed when a program crashes. This is the first step of many. llvm-svn: 66076
* The debugger sometimes lookup dynamically in the runtime to find ivar info ↵Devang Patel2009-02-171-0/+2
| | | | | | | | 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. llvm-svn: 64834
* Unbreak the build on win32.Cedric Venet2009-02-141-1/+1
| | | | | | | | | | 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. llvm-svn: 64554
* Switch from new[] + delete[] to malloc + free since llvm does not catch C++ ↵Evan Cheng2009-02-131-3/+3

* If new[] fails, return 0 rather then trying to dereference a null pointer.Evan Cheng2009-02-131-3/+12

* Add opposite_of and inverse_opt to support -fno- style options. ThisMike Stump2009-01-301-1/+21
| | | | | | is necessary for eventual gcc commmand line compatibility. llvm-svn: 63384
* Clarify comment.Mikhail Glushenkov2009-01-281-1/+6

* APInt's countLeadingOnes() was broken for negative i128 values,Torok Edwin2009-01-271-1/+7
| | | | | | | | | 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. llvm-svn: 63107
* Add method raw_fd_ostream::seek() for random access within a file.Ted Kremenek2009-01-261-0/+6
| | | | llvm-svn: 63044
* Introduce two DWARF attribute extentions DW_AT_APPLE_optimized, ↵Devang Patel2009-01-231-0/+2
| | | | | | | | | | | | 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. llvm-svn: 62888
* Do not use host floating point types when emittingDale Johannesen2009-01-212-7/+2
| | | | | | | | | 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. llvm-svn: 62712

* Make special cases (0 inf nan) work for frem.Dale Johannesen2009-01-211-23/+63
| | | | | | | | Besides APFloat, this involved removing code from two places that thought they knew the result of frem(0., x) but were wrong. llvm-svn: 62645
* Add an IEEE remainder function, which is notDale Johannesen2009-01-201-1/+39
| | | | | | | | fully implemented yet and not used. This is mainly to clarify that APFloat::mod implements C fmod, not remainder. llvm-svn: 62593
