* Allow '+' to appear in APInt strings, and add more unit tests.Erick Tryzelaar2009-08-211-6/+11

* Switch to SmallString::str from SmallString::c_str, and removeDaniel Dunbar2009-08-191-3/+4
| | | | | | SmallString::c_str. llvm-svn: 79456
* Convert APint::{fromString,APInt,getBitsNeeded} to use StringRef.Daniel Dunbar2009-08-131-17/+22
| | | | | | - Patch by Erick Tryzelaar, with some edits (and a bug fix) from me. llvm-svn: 78885
* Add attempted idiotproofing comment per review.Dale Johannesen2009-08-121-1/+2
| | | | llvm-svn: 78825
* Fix a nondeterministic bug in APInt::roundToDouble;Dale Johannesen2009-08-121-2/+2
| | | | | | | | when !isSingleWord() but getActiveBits() is small, we were using the pointer value instead of the low word of the integer value. llvm-svn: 78821
* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-4/+4
| | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
* Switch to raw_ostream.Daniel Dunbar2009-07-131-35/+35
| | | | llvm-svn: 75451
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-4/+5
| | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
* Reapply 74494, this time removing the conflicting definition of operator<<Dan Gohman2009-06-301-0/+6
| | | | | | in APIntTest.cpp. llvm-svn: 74550
* Temporarily revert r74494. It was causing failures in the unit tests.Bill Wendling2009-06-301-6/+0
| | | | llvm-svn: 74515
* Define an operator<< for APInt to be used with std::ostream.Dan Gohman2009-06-301-0/+6
| | | | | | | This will allow it to be used in unittests that use gtest's EXPECT_EQ. llvm-svn: 74494
* 80 column violation.Evan Cheng2009-05-211-1/+1
| | | | llvm-svn: 72235
* Fix whitespacing (space after switch).Mike Stump2009-05-131-6/+5

* Move helper functions for optimizing division by constant into the APIntJay Foad2009-04-301-0/+92

* Fix PR4040: APInt's string constructor is too strictChris Lattner2009-04-251-7/+9
| | | | | | patch by Jeff Yasskin! llvm-svn: 70058
* 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
* Fix comment typo.Duncan Sands2009-03-191-1/+1
| | | | llvm-svn: 67302
* 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
* 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
* Remove uses of uint32_t in favor of 'unsigned' for better Chris Lattner2009-01-211-193/+193
| | | | | | compatibility with cygwin. Patch by Jay Foad! llvm-svn: 62695

* rearrange some code.Chris Lattner2008-10-111-6/+6

* Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner2008-08-231-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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
* Move the fast-path (<=i64) cases of various APInt methods inlineChris Lattner2008-08-201-150/+40
| | | | | | | and the slow-path cases out of line. This speeds up instcombine a bit in real world cases. Patch contributed by m-s. llvm-svn: 55063
* It's not necessary to check if a value is null before delete[].Dan Gohman2008-08-201-1/+1
| | | | llvm-svn: 55053
* Rework the routines that convert AP[S]Int into a string. Now, instead ofChris Lattner2008-08-171-95/+98
| | | | | | | | | | | | | | | | | returning an std::string by value, it fills in a SmallString/SmallVector passed in. This significantly reduces string thrashing in some cases. More specifically, this: - Adds an operator<< and a print method for APInt that allows you to directly send them to an ostream. - Reimplements APInt::toString to be much simpler and more efficient algorithmically in addition to not thrashing strings quite as much. This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the asmprinter. This also fixes a bug I introduced into the asmwriter in a previous patch w.r.t. alias printing. llvm-svn: 54873

* As comments said, for negative value, the arithmetic Zhou Sheng2008-06-051-1/+1
| | | | | | | | | over-shift-right should return -1. So here it should be signed-extended, when bitwidth larger than 64. test case: llvm/test/ExecutionEngine/2008-06-05-APInt-OverAShr.ll llvm-svn: 51999

* A quick nm audit turned up several fixed tables and objects that wereDan Gohman2008-03-251-1/+1

* Add support to APInt for shift and rotate operations with APIntDan Gohman2008-02-291-0/+27

* Fixed bug in APInt::Profile() where the BitWidth field was not included in theTed Kremenek2008-02-191-0/+2

* Add a new function tcExtract for extracting a bignum from anNeil Booth2007-10-081-34/+76
| | | | | | | | | | | | | arbitrary range of bits embedded in the middle of another bignum. This kind of operation is desirable in many cases of software floating point, e.g. converting bignum integers to floating point numbers of fixed precision (you want to extract the precision most significant bits). Elsewhere, add an assertion, and exit the shift functions early if the shift count is zero. llvm-svn: 42745
