* Add opposite_of and inverse_opt to support -fno- style options. ThisMike Stump2009-01-301-1/+21

* 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

* 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

* Overload AddInteger on int/long/long long instead of on int/int64_t,Dan Gohman2008-11-031-6/+16
| | | | | | | to avoid overload ambiguities. This fixes build errors introduced by r58623. llvm-svn: 58632

* Fix command-line option printing to print two spaces where needed,Dan Gohman2008-10-141-1/+1
| | | | | | | | | instead of requiring all "short description" strings to begin with two spaces. This makes these strings less mysterious, and it fixes some cases where short description strings mistakenly did not begin with two spaces. llvm-svn: 57521
* Change TAG_ names to DW_TAG for gcc (testsuite) compatibility.Dale Johannesen2008-10-121-59/+59

* Add a "loses information" return value to APFloat::convertDale Johannesen2008-10-091-14/+37

* Rename APFloat::convertToAPInt to bitcastToAPInt toDale Johannesen2008-10-091-4/+4
| | | | | | | make it clearer what the function does. No functional change. llvm-svn: 57325
* Mark negative-zero-to-int conversion as Inexact,Dale Johannesen2008-10-071-1/+2
| | | | | | | | | since -0.0 can't be represented as an int. This prevents llvm from reducing -0.0 to a load-and-convert of int 0. Fixes ieee.exp/mzero[2356].c in gcc testsuite. llvm-svn: 57224
* Be more precise about which conversions of NaNsDale Johannesen2008-10-061-3/+18
| | | | | | | | are Inexact. (These are not Inexact as defined by IEEE754, but that seems like a reasonable way to abstract what happens: information is lost.) llvm-svn: 57218
* Temporarily revert functionality change from my previous patch;Dale Johannesen2008-10-061-2/+1

| | | | | | | | | | | | | | | | | | | | | | | | use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. llvm-svn: 55263
